specific Embodiment approach 1

[0014] Specific implementation mode one: combine figure 1 and figure 2 Illustrate this embodiment, a kind of prestressed anchor clip method for removing brick masonry wall piece in this embodiment is specifically carried out according to the following steps:

[0015] 1. Place the wooden square 6 on the front and rear sides of the demolished brick masonry wall piece 1 and fix it;

[0016] 2. Assemble the two sets of prestressed anchor clip frames on both sides of the demolished brick masonry wall piece 1;

[0017] 3. Install a prestressed lead screw 7 between the upper frame 2 and the lower frame 3 of the prestressed anchor clip frame, and adjust the screw nut to provide prestress for the prestressed anchor clip frame;

[0018] Four, pass steel wire rope through the cross bar that the left frame 4 of prestressed anchor clip frame and the top of right frame 5 are provided with, can carry out hoisting and transportation that demolition brick masonry wall piece 1 is carried out...

specific Embodiment approach 2

[0019] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the demolition of the brick masonry wall piece 1 in step 1 is dismantled by industrial demolition. Others are the same as the first embodiment.

specific Embodiment approach 3

[0020] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the frame of the prestressed anchor clip described in step two is composed of an upper frame 2, a lower frame 3, a left frame 4 and a right frame 5; The frame 2 and the lower frame 3 are arranged in parallel, bolt holes are provided at both ends of the upper frame 2 and the lower frame 3, and the upper frame 2 and the lower frame 3 are respectively connected to the demolished brick masonry wall piece 1 by bolts; The left frame 4 is vertically arranged at the left end of the upper frame 2 and the lower frame 3, and the right frame 5 is vertically arranged at the right end of the upper frame 2 and the lower frame 3; the flanges of the upper frame 2 and the lower frame 3 A pair of through holes are provided for connecting the prestressed screw 7. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to the technical field of civil engineering construction, in particular to a prestress anchor clamping method for dismantling a brick masonry wall piece. The invention aims to solve the problems that a wall piece is easy to incline in a transportation and hoisting process of dismantled brick masonry wall pieces, is damaged and cannot be safely and stably transported and hoisted to a construction part. The method comprises the steps that the front face and the rear face of the dismantled brick masonry wall piece are each provided with a prestress clamping frame, and the prestress clamping frames are connected with the wall piece through bolts. The prestress clamping frame is composed of an upper frame, a lower frame, a left frame and a right frame and lead screws. According to the invention, the overall performance of the demolition of the brick masonry wall piece is enhanced. Compared with the prior art, the anti-bending capacity outside the plane of the wall piece is improved, the wall piece can be simply transported and hoisted through an embedded part like a reinforced concrete component, overturning damage of the wall piece in the transporting and hoistingprocess is avoided, the construction process is simplified, and stable hoisting for dismantling the masonry wall piece is achieved.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to a prestressed anchor clip method for removing brick masonry wall pieces. Background technique [0002] As one of the main building types in our country, brick masonry structure buildings have the characteristics of large number and wide distribution. Due to social development and the update of design and construction standards, masonry structures often cannot meet the new use requirements and the seismic safety required by relevant standards in terms of space and function, resulting in the demolition of a large number of masonry structures. If the demolished masonry is treated as construction waste, it will cause waste of resources and environmental damage. If the scientific demolition and connection method of masonry wall pieces is adopted, the masonry wall pieces can be removed and reused in the first time, which has good economic and social benefits. ...
