Description

The invention relates to the construction, namely to the construction of attic floors above the upper floors of buildings.

There is a method of building superstructure during reconstruction, which consists in the installation of volumetric block rooms, and the subsequent filling of the space with heat-, hydro-, sound-proof materials and roof coating on the outside. (Patent No. 2156341 of the Russian Federation, E04G 23/02, publ. 09/20/2000).

The disadvantage of this method is the significant complexity associated with the device of an additional strapping belt and rail, the need for a large number of additional materials for the device of the finished roof.

There is a method of building add-on in attic-type rooms, which consists in installing structures on the bearing walls of buildings, the add-on is carried out on one or more floors on a flat roof of the technical floor with sheathing with enclosing materials, on the roof there are rails on which the frames are installed. (Patent No. 2122092 of the Russian Federation, E04G 23/02, publ. 20.11.1998).

The disadvantage of this method is the significant complexity, the need for guides and the installation of a large number of additional materials for the device of the finished roof.

The closest technical solution to the claimed invention is a method of building reconstruction, which consists in the fact that after the preparation of the ceiling along the outer walls, brackets are installed on top, and curvilinear elements corresponding to the half-profile of the attic are assembled with brackets on the supporting part, after which the brackets of the external walls are combined with the brackets of the supporting parts of the curved elements, which are then rotated to the design position and fix the second ends of the curved electric coping with each other, in addition, after preparing the outer side of the ceiling above the inner walls, load-bearing columns are erected on which curvilinear elements are supported when installing them in the design position, and before installing curvilinear elements in the design position along the building, they are joined together by load-bearing bonds in pairs and then the space between the curvilinear elements is filled with heat-hydro-sound-insulating materials and the outside is covered with roofing material, also before installing brackets along the bunk of the upper walls on top of the parapet, volumetric roof units with a roofing are installed. (RF patent No. 2078885, E04G 23/00, published 05.10.1997).

The disadvantages of this method are the large metal consumption, the complexity of installation at a construction site, the significant complexity of installing a roofing, heat and sound and waterproofing on a mounted frame.

The task to which the invention is directed is to reduce the complexity and simplify the assembly of the structure, reduce the time of installation of the attic.

This is achieved by the fact that after the installation of a concrete belt around the perimeter of the building, in order to simplify and speed up the installation, the first row of panels is first mounted, consisting of corner panels, attached to the concrete belt with anchors, the subsequent panels are assembled using the mounting truss on the installation horizon or are installed in panels, to simplify installation on four sides of the panel, guide pins are installed that allow you to fix the position of the panels more quickly and without alignment, and a telescopic lift with a wide-shelf, traverse or mounting truss, which is transformed by tilting the panel, moving along the rails, sets the panel or enlarged unit to the design position, the mounting truss does not allow the panels to fold before fixing them on all sides, when installing panel-by-panel, each installed panel is propped up to prevent deflection, after installation of two complete attic carcass blocks fixing bolts are tightened by tightening the rubber gaskets for waterproofing the structure, subsequent roof attic roof blocks pa are assembled, also fastened to the previous ones, with the help of guide pins and bolted connections, the number of straight-line panels is determined by the required height and span of the building, and the panels can be stacked without mounting truss and telescopic lift - manually, from working scaffolds, the panel joints on the outside are closed elongated and cross-shaped filaments for more reliable waterproofing, the ends of the attic roof are monolithic in the bearing end walls, and I also monolize all technological holes Xia, such as air ducts.

The invention is illustrated by the following drawings, where in Fig. 1 the installation of the first row of corner panels, in Fig. 2 - the location of the guide pins and anchors, in Fig. 3 the installation of the panels according to the first embodiment, in Fig. 4 - the order of installation in the first embodiment, in Fig. .5 - installation of panels according to the second embodiment, in Fig.6 - sequence of installation according to the second embodiment, in Fig.7 - installation of panels according to the third embodiment, in Fig.8 - sequence of installation according to the third embodiment.

The proposed method for the attic floor superstructure is implemented as follows.

According to the first option, on the installation horizon and arranged concrete belt 1 around the perimeter of the building, first, using anchors 2, corner panels 3 are installed on both sides of the building, after which an assembly of the unit 4 of the roof top of the attic type is performed on the mounting frame 5, used to prevent folding and deflection of the loose frame using the guide pins 6. After assembling the top of the frame on the mounting truss using a telescopic elevator 7 moving along the rails, the mounting truss is raised, installed Bringing the enlargement unit into the design position with fastening to the lower corner panels, with the help of guide pins and bolts, the subsequent rows of panel blocks are fastened to the previous one using bolts and guide pins around the perimeter of the panel. After the construction of the frame, the ends of the roof are monolithic in stone bearing end walls or, with the help of a light steel profile, any shape can be given to the ends. On the outside of the frame, the joints between the panels are additionally covered by the filigree 8, and the joint of the four panels by a crosswise scapular 9 with the establishment of elongated filigree under it and the fixation of the filigree to the panels.

According to the second option, after installing the bottom row with the help of anchors, we carry out the subsequent installation of the frame element-by-element, i.e. installation in the design position of each panel separately using a telescopic boom with traverse 10 and temporary fixation by supporting struts 11. Installation is carried out from the lower to the upper panels, symmetrically. It is also possible to install panels without a telescopic lift, manually from the working platform.

According to the third option, the attic frame is mounted over the existing roof 12 by way of dismantling only the abutment points of the corner panels, the concrete belt device at the base of the attic frame and manually installing the panels in the design position, also using supporting struts.

The advantages of this method are simplicity, tight assembly time, manufacturability, no need to install additional devices for installation, no work on the facade of the building. With this method of erecting attic floors, it is possible to carry out construction and installation works without resettling residents and without analyzing the existing roof.
