Problems solved by technology

After the shear wall is closed, the root seal is not in place. During the concrete pouring process, a large amount of mortar will be lost, which will easily cause the root rot of the wall.
The traditional wall root mortar sealing often fails due to poor cleaning of the base, insufficient caulking, insufficient mortar strength, etc., and wall root rot is common, making it difficult to meet the control requirements of large real estate companies on the quality of concrete molding

Embodiment 1

[0029] Such as Figure 1 to Figure 3 As shown, a shear wall anti-rotting root angle steel plugging device, the device includes a positioning angle steel 1, a fixed support 2, an anti-seepage installation block 3 and an anti-seepage moving block 4, and the positioning angle steel 1 is fixedly connected to the bottom of the formwork by screws. The top of the fixed support 2 is fixed with a fixed angle steel 5, and the fixed angle steel 5 is arranged at the bottom of the positioning angle steel 1. The fixed angle steel 5 and the positioning angle steel 1 are detachably connected by bolts, and the fixed support 2 is fixed on the ground through anchor bolts. The fixed support 2 An anti-seepage installation block 3 is installed at the bottom of one side opposite to the shear wall. 4 is rotatably connected with an adjustment rod 6, and the end of the adjustment rod 6 away from the anti-seepage moving block 4 freely passes through the fixed support 2 and extends to the side of the fix...

Embodiment 2

[0035] A construction method of a shear wall anti-rot root angle steel plugging device, comprising the following steps:

[0036] A. The spring line at the root of the shear wall, chiseling, cleaning, and welding limit steel bars. The spring line at the root of the shear wall includes the wall position line and the control line 200mm away from the wall on both sides;

[0037] B. Binding and acceptance of the steel bars in the shear wall. The installation position of the steel bars is correct and the binding is firm. At this time, concrete supports should be installed;

[0038] C. The shear wall formwork is closed. The formwork must be firm, sealed, flat, and have sufficient strength, rigidity and stability. Steel nails are used to fix the positioning angle steel 1 and the formwork at the joints of the formwork;

[0039]D. Place the corner sealing device at the root of the shear wall, first install the anti-seepage installation block 3 on the side of the fixed support 2 facing t...

Abstract

The invention discloses a root rotting prevention angle steel plugging device for a shear wall and a construction method, and belongs to the technical field of wall root plugging devices. According tothe root rotting prevention angle steel plugging device, positioning angle steel, a fixed support, fixed angle steel, an anti-seepage mounting block, an anti-seepage moving block, an adjusting rod and an adjusting piece are arranged, the fixed angle steel and the positioning angle steel are connected and fixed through connecting bolts, on one hand, the connecting strength between the positioningangle steel and the fixed angle steel is controlled, and the rollover phenomenon is prevented when the anti-seepage moving block is adjusted to extrude the positioning angle steel; and one the other hand, a formwork is supported in an auxiliary mode to prevent running and form-expanding at the root, and the anti-seepage mounting block and the anti-seepage moving block are adjusted to compress a connecting seam of the anti-seepage mounting block and the anti-seepage moving block, a connecting seam of the positioning angle steel and the anti-seepage moving block and a connecting seam of the anti-seepage mounting block and the ground under the action of the adjusting piece on the adjusting rod, so that the sealing effect of the root is achieved, the quality of the root is guaranteed, the process construction is safe and reliable, the efficiency is high, and the rotten root of the shear wall root can be effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of wall root sealing devices, in particular to a shear wall root rot prevention angle steel sealing device and a construction method. Background technique [0002] At present, most high-rise residential projects are cast-in-place reinforced concrete shear wall structures. After the shear wall is molded, if the root seal is not in place, a large amount of mortar will be lost during the concrete pouring process, which will easily cause the root rot of the wall. The traditional wall root mortar sealing often fails due to reasons such as poor cleaning of the base, insufficient caulking, insufficient mortar strength, etc., and wall root rot is common, making it difficult to meet the control requirements of large real estate companies on the quality of concrete molding. [0003] Therefore, how to provide a root sealing method that is safe in construction, good in construction quality, high in efficiency and can e...
