Scaffolding and the mount of diagonal and horizontal ties of the supporting frames of scaffolding

The utility model relates to construction and can be used in the construction, installation and finishing works during the construction and repair of buildings and structures both inside and outside the facility.

A known construction of scaffolding (see RU patent for invention No. 2158813, 7 MKI E04 G 1/06, 1/12, 10.11.2000) 1, including vertical racks on which support brackets, tubular longitudinal ties and tubular transverse ties are rigidly fixed . The fastening between the vertical posts, tubular longitudinal and transverse connections is carried out by means of a support bracket and a wedge, equipped with a stop and made in its lower part with a cutout in the form of a segment. The support bracket is made of a rectangular plate curved in the form of a bracket; a through hole is made on one of its sides, ending with a saddle on its shelf. The support brackets are rigidly mounted at their ends on vertical racks in pairs against each other and in perpendicular planes. Each end of the tubular longitudinal connection and the tubular transverse connection is made upset, the cross-section of which is a rectangle with rounded corners. A cut was made on its large sides, and holes for a wedge were made on its smaller sides. One of the smaller sides of the rectangle is designed to be mounted on a saddle.

For safe work on tiers, fences, railings, stairs and flooring made of shields are provided.

The described construction has insufficient stability in space, in particular when used without fastening to the wall and installing many tiers, which is due to the presence of only longitudinal and transverse ties and the absence of diagonal ties. The presence of four support brackets on each vertical rack in perpendicular planes does not provide for the fastening of diagonal ties.

There are forests for construction and installation works (see ed. CB.SU. No. 817174, 3 MKI E04 G 7/24, publ. 03/30/1981, B.I. No. 12) 2, in which a mounting unit for braces and braces is provided to accelerate the installation of scaffolding and the versatility of their application. To do this, scaffolding includes racks with ribs attached to them with holes, struts and braces, at the ends of which connecting devices are mounted, each of which contains an end element with a cantilever pin passed into the hole in the rib, an axis passing through the hole made in the end element, a swivel tab located on the axis and fixed by means of a clamping element located on the same axis. The disadvantage of the described design is the complexity of the device and manufacturing technology of the connecting node, which consists of seven parts.

Closest to the claimed technical solution, selected as a prototype (see U, RU,. No. 17554, 7 MKI E04G 1/00, publ. 10.04.2001) 3, are multi-storey scaffolding containing tubular prefabricated vertical frames with connecting

nodes interconnected by diagonal and horizontal connections on the brackets, horizontal decks, stairs, screw jacks and lifts. The tubular elements are made of square tubes and are interconnected by guides located inside the upper part of the vertical frame rack. The bracket is made in the form of rods that pass through the racks of the layers; it has frames and has a pivotally mounted movable part at the end opposite the rack, and the ladder located in its plane is an element of the frame stiffness. In addition, horizontal ties are made in the form of a tubular element with oblate end parts provided with mounting holes.

The diagonal connections are made in the form of two tubular elements pivotally connected in the center and having tapered end parts with fasteners and installed in a checkerboard pattern relative to the plane of the scaffolds.

However, the presence of diagonal ties of the bearing frames installed in a checkerboard pattern relative to the plane of the scaffolds is not enough to ensure rigidity and stability of the structure. The implementation of tubular elements from square tubes complicates the manufacturing technology of scaffolding. The design of the swivel of the mount of the diagonal and horizontal ties of the supporting frames is not convenient enough for quick assembly and dismantling of scaffolding.

The technical result of the claimed utility model is to increase the rigidity and stability of the scaffold design, increase the level of unification and reduce labor costs in the manufacture and installation of scaffolding.

The technical result is achieved in that the scaffolds comprise tubular prefabricated vertical load-bearing frames with docking assemblies interconnected by fasteners with diagonal and horizontal connections, relative to the scaffold plane, made in the form of pipes with tapered end sections in which fastening holes are made. Forests also contain stairs, horizontal flooring and screw jacks with thrust bearings.

According to a utility model, each vertical supporting frame is connected to the subsequent supporting frame by two diagonal connections and one horizontal connection in the scaffold planes external and internal to the building object, and horizontal ties form a railing along the entire length of the scaffolds, respectively, one rack of the supporting frame is equipped with two attachment points in the upper and lower parts, and the other rack is equipped with a mount in the middle part.

Another difference is that the horizontal pipes of the supporting scaffolds of the scaffolding are connected to the vertical posts by a welded joint and are provided with two rigid welded wedges in the end sections.

The technical result is also achieved by the fact that the attachment point for the diagonal and horizontal connections of the supporting frames of the scaffolding comprises a bracket made in the form of a rod rigidly connected to the rack of the carrier frame and having a pivotally mounted movable element at the end opposite the rack.

According to a utility model, the bracket rod has a cross section corresponding to the diameter of the holes in the tapered end sections of the pipes for diagonal and horizontal connections of the supporting frames. In the vertical plane of the rod

A longitudinal slot is made in which a movable element in the form of a metal plate is placed on the transverse axis of rotation passing through the holes in the lateral parts of the rod, and its axis of rotation passes through the plane of the movable element above its transverse axis of symmetry.

Another difference is that in the attachment point of the diagonal and horizontal connections of the supporting frames of the scaffolding, the bracket rod is connected to the support of the supporting frame by a welded joint.

The construction of scaffolding and the mount of diagonal and horizontal ties of the bearing frames is illustrated by drawings, where:

in FIG. 1 shows a supporting frame of scaffolding, view BB;

in FIG. 2 shows scaffolds assembled, where in perspective view, b-view BB;

in FIG. 3 shows a pipe end portion of a carrier frame with a tapered end portion and rigid lobes;

in FIG. 4 shows a pipe for diagonal and horizontal connections of the bearing frames, view BB;

in FIG. Figure 5 shows the attachment point of the diagonal and horizontal connections of the bearing frames, where a is a perspective view, b is a view of A-A, and c is a view of BB.

Scaffolds contain tubular vertical supporting frames 1 with docking assemblies 2, vertically connected by fasteners 3. The supporting frames 1 are an element for scaffolding modules and are made of pipes of the same circular cross section. The transverse pipes 4 of the supporting frames (Fig. 2) have tapered end sections and, when the frame is manufactured, are inserted into the slots corresponding to them in the vertical posts of the frame 1 and welded. The end sections of the transverse pipes 4 are also provided with two wedges 5 imparting structural rigidity (Fig. 3).

Each vertical supporting frame 1 is connected to the subsequent frame by two diagonal connections 6 in the vertical plane of the scaffolds and one horizontal connection 7 in the opposite plane of the scaffolding and forming a blocking railing along the entire length of the scaffolds.

The connections between the frames are made of pipes of the same circular cross section and have end flattened 5D1ast with mounting holes 8, One rack of the carrier frame is equipped with fasteners 9 in the upper and lower parts, and the other rack is equipped with one fastener 9 in the middle part (Fig. 1).

The mounting unit for the diagonal ties of the supporting frames of the scaffolds (Fig. 1.4) contains a bracket 9 made in the form of a rod 10, which is rigidly fixed in the rack of the frame 1 and has a pivotally mounted movable element I. at the opposite end from the rack. The rod 10 has a cross section smaller than the diameter of the mounting holes 8 of the end sections of the diagonal and horizontal ties of the supporting frames 1. This provides free dressing on the rod 10. of the end sections of the diagonal ties 6 and horizontal ties 7. In the vertical plane 10, a longitudinal slot 12 is made. Across the slot 12, the axis of rotation 13 of the movable element 14 is installed, passing through the lateral parts of the rod 10. The movable element 14 is made of a heavy metal plate and placed along the slot 12. The axis of rotation 13 passes through the wide plane of the movable element 14 above its transverse axis of symmetry. In this case, the center of gravity of the movable element 14 is located below its centers of gravity.

Scaffolding also has stairs 15, horizontal floorings 16, and screw jacks 17 with thrust bearings 18.

diagonal tubular connections 6 and 7 are manufactured in the factory. Two brackets 9 with movable elements 14 pivotally mounted on them in one upper vertical strut of the supporting frame 1 are rigidly fixed in the upper and lower parts, and one bracket with pivotally mounted movable element 14 is rigidly fixed on the other vertical strut in its middle.

This arrangement of fastening elements allows you to connect the vertical uprights of the carrier frames 1 to each other with diagonal 6 and horizontal 7 connections in the outer and inner scaffold plane relative to the construction object.

When assembling the first tier of the scaffolds at the place of use, spline; end sections with holes 8 of pipes 6 and 7 are put on the rod 10 of the attachment site (Fig. 4). For this, the movable element 4 of the attachment node is rotated from a vertical plane in which it constantly resides, since its center of gravity is below the horizontal axis of symmetry of the metal plate in a horizontal plane.

After connecting the required number of modules in one tier, they are interfered with from above, horizontal floorings 16 are placed (Fig. 2 a, b). Then, the vertical struts of the layers; their frames are extended upwards by means of connecting elements, for example, in the form of pieces of pipes of a larger diameter equipped with fixing holes and bolts (Fig. 1).

Screw jacks 17 with thrust bearings 18 can be equipped with wheels with the ability to move the scaffolding along the rails, placed on the ground.

The implementation of scaffolding, consisting of the same modules, each having diagonal and horizontal connections of the supporting frames, increases the rigidity of the scaffold design and their stability

when using, especially in the presence of many tiers. The use of standardized elements and simple attachment points allows you to increase the level of unification and reduce labor costs in the manufacture and installation.
