Problems solved by technology

However, when an earthquake occurs, the prefabricated panels will still experience horizontal displacement, resulting in falling off, wall collapse, etc., and the escape time is only a little longer than that of the original house, and the reinforcement effect is very limited.

Embodiment Construction

[0024] A construction scheme for reinforcing joints of prefabricated slabs in a load-bearing wall of a brick-concrete structure, characterized in that:

[0025] The first step: base treatment: setting out wire positioning, grinding and smoothing the plate and wall base where the angle steel is installed, cleaning it up and opening the bolt holes at the corresponding positions;

[0026] The second step: angle steel blanking processing: cut the corresponding length of angle steel according to the length of the load-bearing wall and open the bolt holes at the corresponding positions;

[0027] Step 3: Hole filling of the prefabricated panel: within 1000mm of the end of the prefabricated panel, the holes shall be filled with pouring glue, etc.;

[0028] Step 4: Angle steel installation: Install the finished angle steel on the upper, lower, left, and right corners at the junction of the board and wall, and tighten the bolts;

[0029] Step 5: Angle steel injection: fill the gap betw...

Abstract

The invention discloses a construction solution for reinforcing joints on a load bearing wall and and precast slabs of a brick-concrete structure. The reinforcing solution only relates to a brick-concrete structure house provided with the load bearing wall and the precast slabs. The joint construction method comprises the following steps that holes of the prefabricated slabs are filled with glue in the 1000 millimeters range of the end parts of the left and right prefabricated slabs placed at the upper part of the load bearing wall, reversely four pieces of full-length angle steel are installed at four internal corners at the upper and lower parts of the joint of wallboards, and oppositely pulling and anchoring are conducted on the four pieces of angle steel in pairs by using opposite-penetrating bolts. The construction solution has the advantages that the integrity of the brick-concrete structure house is enhanced, the anti-seismic capacity is higher, falling of the prefabricated slabs and falling of the load bearing wall caused by the transverse horizontal effect are more effectively restrained during an earthquake, and the escape time of people is prolonged.

Description

technical field [0001] The invention discloses a construction scheme for reinforcing joints of prefabricated slabs in a brick-concrete structure load-bearing wall, and belongs to the technical field of building construction. Background technique [0002] Seismic reinforcement of old brick-concrete structures is very common in our country. The situation encountered in this project is a reinforcement node in the load-bearing walls and upper and lower positions of prefabricated slabs in brick-concrete structures. According to the conventional method, only one full-length angle steel is installed on the wall below the prefabricated slab to increase the shelving length of the prefabricated slab. However, when an earthquake occurs, the prefabricated slab will still experience horizontal displacement, resulting in falling off, wall collapse, etc., and the escape time is only a little longer than that of the original house, and the reinforcement effect is very limited.
