SU1196473A1 - Reinforcement post for structures - Google Patents

Description

The invention relates to building structures and can be used in the reconstruction of buildings and structures to strengthen the columns, which are adjacent bolts.

The purpose of the invention is to reduce the complexity of the gain and increase the safety of work.

FIG. 1 shows the rack, a general view}. In FIG. 2 — node I (upper node) in FIG. 1} in FIG. 3 - node nd (lower node at the moment of creation of the thrust force) nafig. 1} in FIG. 4 shows the node W (lower stand assembly after installation) in FIG. 1 ·, in FIG. 5 is a section A-A in FIG. 3; in fig. 6 is a section BB in FIG. four.

Telescopic column 1 column reinforcement is placed next to the reinforced column 2 and consists of two parts, the upper part of the rack can move freely in the inner lower part of the rack.

The lower part of the telescopic stand 1 is carried out in the factory and contains a tubular section 3 with a camera for a jack, having a window for installing a jack inside the stand, a support plate 4 with strips 5 welded to it at a distance K + 2 mm from the center of the stand,

Where K is the radius of the lower part of the jack, which makes it possible to automatically fix the jack in the center of the rack and prevents arbitrary movement of the jack on the base plate 4 when creating the spacer reinforcement in the rack, and stiffening ribs 6.

The upper part of the rack is made of a tubular part 7, a lower support plate 8 with stiffening ribs 9 welded to it, an abutment ring 10 and an upper supporting plate 11 with stiffening ribs 12 welded to it.

I

Strengthening (unloading) of the column 2 of the proposed rack is as follows.

After selecting and preparing the site 5 mounting rack gain is performed

installation rack 1 in the design position.

A jack 13 is inserted into the chamber of section 3 of the rack through the “window”, which creates an expansion force, which is transmitted from the jack to the base plate 8, the tubular section 7, the supporting plate 11 and then to the structure (beam) ι

15 Upon reaching the design effort in the rack, the gap between the stop ring 10 and the upper tubular part 3 is set (wedged) in the semi-ring 14 and connected to the joining points with their assembly welding seams. Semirings 14 fix the movable (upper) part of the rack and do not allow the reduction of the spacer force in rack 1 after dismantling the jack

25 13. Then the jack is removed from the measure. The insert 15, which is made to the size of the "window", from a pipe with a diameter equal to the diameter of part 3, is closely inserted into the "window" of part 3 of the rack

30 racks. Preliminary to the insert 15 is welded edge 16 stiffness. The insert 15 and the stiffener rib 16 are attached by mounting welds to part 3 of the rack.

₃₅ The application of the invention allows to significantly reduce the metal of the elements of the rack and the amount of assembly {welding required to effect the reinforcement of the column by installing a stand of ₄₀ ki, strained by a jacking method.

In addition, it simplifies the implementation of the mounting joint of the telescopic elements of the rack with sufficient use of only one welder. ka for welding.
