Abstract

The invention relates to construction and can be used in the reconstruction of an industrial building with a simultaneous increase in its height. The aim of the invention is to simplify the production of works for the reconstruction of a building from modules with three longitudinal and transverse rows of columns and a reduction in the energy intensity of the lifts used. The method of reconstruction of an industrial building by diluting the columns is characterized by the fact that the rise of the coating is carried out by alternately hanging the ends of the slabs of the coating along the middle transverse row of columns 1 of the module when the elevator is moved along it, and the dismantling of the columns 1 is performed along with the dismantling of transverse beams 2. 7 or .

Description

The invention relates to the construction and can be used in the reconstruction of an industrial building.

There is a known method of reconstruction of an industrial building, in which, under existing building structures, a new span structure is introduced in the form of a polygonal three-hinged arch and the load from the truss structures is passed to it, followed by dismantling the removed column.

The disadvantages of this method are its complexity, the need for additional structures in the form of a three-hinged arch, which increases the consumption of materials for the method.

Also known is the method that is closest to the proposed one and adopted as a prototype, namely, that the slab of the coating resting on the transverse beams is lifted together with the beams using a lifting device in the zone where the beams meet each other on the column to be dismantled. fix the coating in the new design position and dismantle the column 2.

The disadvantage of this method is the need for sufficiently numerous additional elements for installing the coating in a new position and fixing it. In addition, the method is time consuming to implement.

The aim of the invention is to simplify the production of works in the reconstruction and reduce the energy intensity of the used lifting devices. In this case, it is meant that the reconstructed building consists of modules with three longitudinal and transverse rows of columns.

The goal is achieved by the fact that the method of reconstruction of an industrial building by diluting the columns involves lifting, by lifting the cover plates, supported on the transverse beams, fixing the cover in a new design position and dismantling the columns. The rise of the coating is carried out by alternately posting the ends of the coating plates along the middle transverse row of columns of the module when the lifter is moved along it, and the dismantling of the columns is carried out together with the dismantling of the transverse beams.

As a result of the implementation of the method, the columns are thinned, and the space of the building increases due to the elevation of the plates. In addition, the plates are self-reinforcing due to the fact that when the position of the plates changes from a horizontal position to an inclined plate, they begin to work not only for bending, but also for compression.

FIG. 1 shows a module of an industrial building, top view; in fig. 2 - the same, longitudinal section; in fig. 3 shows the node I in FIG. 2; in fig. 4 shows section A-A in FIG. 3; in fig. 5 — node AND in FIG. 2; in fig. 6 is a section BB in FIG. five; FIG. 7 is a section B-B of FIG. five..

FIG. 1-7, the following symbols are introduced; columns of T.balki 2, slab 3 of coating, a strut device 4, consisting of a base 5 and composite struts 6 pivotally connected with it, ti 7, a coupling 8, supporting bases 9, limiting plates 10, a pin 11, fixings 12 cover plates; embedded parts 13 beams; wedge-shaped gaskets 14, spreader angles 15, reinforcement cages 16, reinforcing meshes 17, concrete 18 monolithing.

Example. First, the plates of the 3 coatings to be lifted are unloaded. To do this, remove the roll carpet and roof insulation, dismantle the process equipment and communications, the light and erection ion lights. Then, the seams of fastening of embedded parts of 12 slabs with embedded parts of 13 beams are released. Then the pins 11 are welded to the mortgage parts of the 12 raised slabs of the floor and the restrictor plates 10 of the movement of the lifted plates 3 of the floor to the mortgage parts of the 13th beams. In the limiting plate x 10 there is an inclined groove along which when lifting the plates 3 of the coating the pin 11 moves. slabs 3 cover

above beam 2 and column 1 to be dismantled to a height of 1 m

The lifting of the cover plates 1 can be carried out in pairs using the strut

devices 4. consisting of base 5 and hinged composite struts b. The composite legs 6 in the middle part have a hinge interface, with the opposite legs 6 in places of the hinge

the couplings are interconnected by means of strands 7, having a sleeve 8 for tension. In the upper part of the pillar 6, they are pivotally connected to the supporting bases 9 supplied under the longitudinal ribs of the raised cover plates. The lifting of the plates 3 of the coating is carried out with the help of the tension coupling 8.

After lifting the plates 3 covers to a predetermined height to the embedded parts of the m 12 plates 3 covers, in the ridge part, the spacer 15 is welded. Then, under the supports of the raised plates 3 covers, wedge-shaped gaskets 14 are installed, which

12 plates of 3 coatings are welded to the mortgage parts and 13 beams to the mortgage parts. Next, the embedded parts of the 12 plates of the 3 coatings are welded to the limiting plates 10. After that,

lift the device and move it to lift the next pair of plates 3 cover. After lifting the slabs of the module of the industrial building, you can begin to embed joints between

the ends of the raised plates of the coating. For this, formwork is installed at the bottom of the joint, reinforcement cages 16 and reinforcement meshes 17 are installed, concrete 18 is placed in monolithing, After monolithing

joints of raised slabs restore roofing. To reduce the load on the reconstructed part of the coating, it is recommended that the roof above the raised slabs of the third coating be lightweight.

The snow load on the pitched portions of the raised slabs of coating is also somewhat reduced. With this method of reconstruction of an industrial building, an additional load from the coating is transferred to the neighboring from the frame to be dismantled. Dismantling of the unloaded columns and beams 2 of the module can be carried out by known methods.

Compared with the known method of building renovation, the proposed method, in which the parts of the building to be reconstructed and the elements associated with them are completely disassembled and installed in a new design position, materials are significantly saved because they are excluded.

many fastener details. Increasing the manufacturability of the method, as compared with the baseline, causes an increase in labor productivity.

Formula of the method of reconstruction of an industrial building by diluting the columns, including lifting by means of a lifting device of the covering plates supported by the transverse beams, fixing the coating in a new design position and dismantling the columns, differing in that. what. with

in order to simplify the work on the reconstruction of a building of modules with three longitudinal and transverse rows of columns and reduce the energy consumption of the lifts used, the rise of the coating is carried out by alternately hanging the ends of the coating plates along the middle transverse row of the lifting
