Description

Technical field

The invention relates to the field of construction of buildings and structures and is intended for connecting long building elements, including beams and racks.

State of the art

A device is known - a closed cubic connector (patent US 4271654, Fig. 1A, 1B, 1C, 3A, 3B and 4, publication date 09.06.1981). The closed cubic connector is made in the form of a metal cube. To facilitate the design, the closed cubic connector has central holes on the side of each of its walls. At the same time, four threaded holes are made on the side of each of the walls. The closed cubic connector is intended for interconnection of long building elements in the form of beams and racks of rectangular or I-beam cross section. At the same time, a connecting plate with four holes for bolts is installed at the end of each long building element. Said holes in the connecting plate are each coaxial with the threaded holes in the closed cubic connector.

The disadvantage of the known technical solution is low reliability.

A device for connecting building structures is known (RF patent No. 159719, publication date 20.02.2016). The device for connecting building structures is made in the form of a hollow cube. At the same time, an inlet is formed to provide access to the cavity on at least one of the walls of the hollow cube. In the remaining walls of the hollow cube, holes are made for the passage of fasteners. The holes are rectangular in shape with rounded edges. The implementation of the connection by means of a single fastener provides low reliability during operation.

The disadvantage of the known technical solution is low reliability.

The closest technical solution (prototype) is an open cubic connector (patent US 4271654, Fig. 8, publication date 06/09/1981). An open cubic connector is made in the form of a hollow cube with at least two bevelled edges. One of the walls of the open cube connector is made with an inlet providing access to the internal cavity of the cube. At the same time, four holes for fasteners are made in each of the remaining walls of the open cubic connector. An open cubic connector is designed to connect long building elements in the form of beams and racks of a rectangular or I-beam cross section. At the same time, a connecting plate with four holes for fasteners is installed at the end of each long building element. These holes in the connecting plate are each coaxial with the holes in the open cubic connector. In this case, the holes for fasteners are located inside the perimeter of the cross section of a rectangular beam or rack. Thus, the distance between adjacent fasteners is limited. Each fastener is passed through a corresponding hole in the wall of the open cube connector and a corresponding hole in the connection plate. The fasteners are made in the form of pins screwed into the wall material of the cubic connector and the connecting plate. Thus, the entire load during operation falls on the material of the cubic connector and the connecting plate at the place where the thread is made.

The disadvantage of the prototype is the low reliability.

The technical result of the invention is to increase reliability.

The set technical result is achieved due to the fact that in the junction of building elements containing a connecting element, two posts and three beams, the connecting element contains two first walls, three second walls and a third wall connected to each other to form a rectangular parallelepiped with an internal cavity , as well as fasteners, moreover, the first walls are located on opposite sides of the rectangular parallelepiped with respect to each other, and the second walls are located between the first walls, the fastener is made in the form of an elongated rod with a threaded part, a head and a nut, each post is made with a closed transverse section and is provided with the first plate attached to this rack from one of its ends, perpendicular to the rack, and the first plate is made with the formation of a protruding part with respect to the rack, each beam is made with an I-beam cross section and is equipped with a second plate attached to this beam from the side of one of its ends, perpendicular to the beam, in each first wall and in each second wall, four mounting holes are made, four mounting holes are made in the protruding part of the first plate, four mounting holes are made in the second plate, an inlet is made in the third wall hole, each first plate is attached to its corresponding first wall by means of fasteners, while the head of each fastener is located in the inner cavity, the threaded part is located on the opposite side of the first wall and the first plate with respect to the head of this fastener, it is screwed onto the threaded part nut, each beam is connected to the second connecting wall corresponding to this beam by means of fasteners, while the head of each fastener is located in the inner cavity, the threaded part of the threaded part is located on the opposite side of the second wall and the second plate relative to a nut is screwed onto the threaded part, in a particular case, at least in each first connecting wall and in each first connecting plate, an additional hole is made, in another particular case, each fastener is attached to the corresponding wall.

Disclosure of invention

The main elements of the building element connection unit (hereinafter referred to as the device) are a connecting element, two racks 5, three beams 8 and fasteners 9.

The connecting element is made in the form of a hollow rectangular parallelepiped, in the particular case of a hollow cube. The connecting element consists of two first walls 12, three second walls 10 and a third wall 2. The first walls 12, the third wall 2 and the second walls 10 can be made as separate plate elements connected to each other, for example by means of a welded joint, or can be at least partially made in one piece, for example in the form of curved sheet metal. In this case, the welded connection can be made only along some ribs.

The first walls 12 during the operation of the device are located generally horizontally and are intended for connecting racks 5. The device has two first walls 12. The first walls 12 are located on opposite sides of the cuboid. Each of the first walls 12 has an additional hole 11. The additional hole 11 contributes to the distribution of stress in the material of the first wall 12 during temperature changes. In a particular case, the additional hole 11 is made to allow various communication lines to pass through it, including water supply, gas supply, power supply, and others). Each first wall 12 has at least two fastening holes for fasteners 9. In a particular case, four fastening holes are made in each first wall 12. Mounting holes are located near the corners of the first wall 12.

The second walls 10 are perpendicular to the first walls 12. There are three second walls 10 in the device. Each second wall 10 has at least two mounting holes. In a particular case, there are four mounting holes in each second wall 10. Mounting holes are located near the corners of the second wall 10.

The third wall 2 is located perpendicular to the first walls 12. The third wall 2 is made with access to the inner cavity 13, for example, by making an inlet 14 in it. .

Rack 5 is made in the form of a lengthy element, the length of which is greater than the dimensions of its cross section, and at least one first plate 3 attached to its end. The rack is made hollow with a closed cross section, for example round, square or any other. In a particular case, the rack is made with a quadrangular cross section.

The first plate 3 is a metal plate. The first plate 3 in the particular case is made quadrangular. The dimensions of the first plate 3 are made larger than the dimensions of the cross-section of the rack with the formation of a protruding part. In a particular case, the protruding part can be made along the entire perimeter of the rack element or protrude only from two opposite sides from it. In the first plate 3, in the particular case in its protruding part, fastening holes are made. In a particular case, there are four mounting holes in the first plate 3.

Beam 8 is a long building element, the length of which is greater than the dimensions of its cross section. Beam 8 in the particular case is made with a cross section in the form of an I-beam. Beam 8 is provided with a second plate 1.

The second plate 1 is a metal plate fixed on the end of the beam 8. The second plate 1 in the particular case is made quadrangular. Mounting holes are made in the second plate 1. In a particular case, there are four mounting holes in the second plate 1.

Fastening elements 9 are made with the possibility of fixing the relative position of the structural elements. The fastening element consists of a head 4, a threaded part 7 and a nut 6. The fastening elements 9 are installed in the fastening holes of the first walls 12 and the second walls 10. In this case, the fastening elements 9 can be fixed in these fastening holes, for example, by means of a welded joint.

Each column 5 is connected by a first plate 3 to the first wall 12 of the connecting element corresponding to this column 5. Moreover, each fastener 9 is passed through the fastening hole corresponding to this fastener 9 in the first wall 12 and in the first plate 3. A nut 6 is screwed onto the threaded part 7, from the side of the first plate 3 opposite to the connection with the first wall 12.

Each beam 8 is connected by a second plate 1 to the second wall 10 of the connecting element corresponding to this beam 8. In this case, each fastener 9 is passed through the fastening hole corresponding to this fastener 9 in the second wall 10 and in the second plate 1. A nut 6 is screwed onto the threaded part 7, from the side of the second plate 1, opposite to its connection with the second wall 10.

Implementation of the invention

In the case of using the above elements and means, the invention is implemented as follows.

A connecting element is made from sheet metal by forming kinks and welded joints in the required places until a rectangular parallelepiped is formed. Additional holes 11 are made in the opposite walls (future first walls 12). It is also possible to make additional holes in the second walls 10. Due to this, stress distribution in the material of the connecting element is ensured during temperature changes during operation. In the third wall 2, an inlet 14 is made. In each of the first walls 12 and the second walls 10, four fixing holes are made.

In the prototype, the connecting element is made with beveled ribs, which reduce the wall area and, as a result, the contact area. Due to the execution of the connecting element in the form of a rectangular parallelepiped provide an increase in the contact area of the first plates 3 and the second plates 1 with the connecting element compared to the prototype.

Fasteners 9 are made. Fasteners 9 are placed in the fastening holes of the first walls 12 and the second walls 10. If necessary, the heads 4 are attached to the first walls 12 or the second walls 10 by means of a weld.

Beams 8 are made. At the same time, a second plate 1 is attached to at least one end of each beam 8. Four mounting holes are previously made in each second plate 1. At least one end of each rack 5 is attached to the first plate 3 with the formation of the protruding part. Previously, in each protruding part of the first plate 3, four mounting holes are made.

Thus, due to the implementation of the first plates 3 with protruding parts, provide an increase in the distance between the fasteners 9, thereby increasing the clamping force over the entire area, and thus increasing the reliability of fastening. Due to the removal of fasteners 9 for the perimeter of the cross-section of the rack 5, provide the ability to use as fasteners 9 bolts with nuts 6, and not studs as in the prototype. In this case, it is possible to reduce the thickness of the first plate 3, which reduces the material consumption of the product.

At the construction site, an embedded part is poured into the foundation, made according to the type of the first plate 3 and the second plate 1. Next, a connecting element of one of the first walls 12 is fixed to the embedded part. The connection can be made by bolting or by welding. Next, a rack 5 is attached to the first wall 12, opposite to the one connected to the embedded part. In this case, the first plate 3 of the rack 5 is aligned with the first wall 12 and each fastener 9 is passed through its corresponding mounting hole in the first plate 3. Into the internal cavity 13 of the connecting element, a tool is inserted to hold the head 4, if there is no fastening of the head 4 to the first wall 12. On the opposite side of the fastener 9, in relation to the head 4, a nut 6 is screwed onto the threaded part 8 and tightened.

At the opposite (upper) end of the rack 5, another connecting element of one of its first walls 12 is fixed. In this case, the third wall 2 is located on the side of the street wall of the building. Beams 8 are attached to the second walls 10. In this case, the second plate 1 of each beam 8 is aligned with the second wall 10 of the connecting element corresponding to this beam 8. Each fastener 9 installed in the second wall 10 is passed into the corresponding fastening hole of the second plate 1 and fixed by means of a nut 6. Thus, beams 8 are attached along all three second walls 10.

Due to the fastening by means of fasteners 9 containing a nut 6, the load is distributed on the first plate 3 from the lateral distortions of the rack 5, in contrast to the prototype, where the load is entirely perceived by the threaded surfaces of the first plate 3 and the first wall 12.

Thus, due to the implementation of the connection node of building elements with a set of features described in the formula, it provides an increase in its reliability.
