Problems solved by technology

[0003] The original method of fixing the cantilevered steel is usually to directly embed the "shaped" round steel hoop on the reinforced concrete beam slab. After the concrete pouring is completed and the strength is reached, the cantilevered steel is inserted into the pre-buried hoop. Then use a wooden wedge to smash into the gap between the hoop and the section steel; after the cantilevered scaffolding is used and dismantled, the pre-embedded round steel hoop in the shape of "a few characters" will be cut off, which will waste the round steel used to make the hoop
Later, casings were pre-embedded on the reinforced concrete beam slab. After the concrete pouring was completed and reached a certain strength, the small bottom mold of the beam slab was removed, and then the U-shaped bolts were installed upside down and inserted into the steel on the upper plane of the cantilevered steel. The pressure plate and steel backing plate are finally tightened and fixed with double nuts; after the cantilevered scaffolding is removed, the nuts are loosened, and the U-shaped bolts are pulled out in reverse. The U-shaped bolts, nuts, steel pressure plate, and steel backing plate can be recycled and reused; but Its disadvantage is that the fixed position of the reserved sleeve and steel frame is affected by the force of concrete pouring and vibration, which will cause deviation and affect the installation of U-shaped bolts; therefore, there is an urgent need for a convenient and practical underground structural wall panel at the construction site Construction method of casing plugging

Embodiment Construction

[0020] Such as Figure 1-3 As shown, a construction technique of a cantilever-shaped steel fixing bolt and a protective cover that can be used repeatedly includes the following steps:

[0021] Step 1: Complete the laying of the beam-slab bottom formwork 1 according to the construction method of the reinforced concrete beam-slab 8 structure, mark the position of the U-bolt 3 on the beam-slab bottom formwork 1 according to the scaffolding design plan, and place the customized U-shaped The bolt 3 is inserted into the prefabricated installation base 2, and the plane of the installation base 2 is closely connected with the upper surface of the beam plate bottom formwork 1, and the iron nail 4 is smashed into the hole on the ear plate of the prefabricated installation base 2 to fix the installation base 2;

[0022] Step 2: According to the construction method of the reinforced concrete beam slab 8 structure, the binding of the upper reinforcement mesh 6 and the lower reinforcement ...

Abstract

The invention discloses a reusable overhanging type steel fixing bolt and protecting sleeve and a construction process thereof. The reusable overhanging type steel fixing bolt and protecting sleeve and the construction process thereof aim to solve the problem that a U-shaped bolt for fixing overhanging type steel is difficult to fix, reduce the embedded mounting difficulty of the U-shaped bolt andreinforce the thread protection of the U-shaped bolt, thereby laying a foundation for repeated application of the U-shaped bolt, and the universality of green construction is fully reflected.

Description

technical field [0001] The invention relates to a construction process of a cantilever-shaped steel fixing bolt and a protective cover that can be used in turnaround, in particular to a special fixing frame for reserved sleeves (including outer baffles, pull rods and railings) Construction technology of waterproof layer. Background technique [0002] With the development of building construction technology, buildings grow taller and taller. In the construction process of high-rise buildings, cantilevered scaffolding has been widely used. During the erection of cantilevered scaffolding, the fixation of cantilevered steel is an unavoidable problem. [0003] The original method of fixing the cantilevered steel is usually to directly embed the "shaped" round steel hoop on the reinforced concrete beam slab. After the concrete pouring is completed and the strength is reached, the cantilevered steel is inserted into the pre-buried hoop. Then use a wooden wedge to smash into the ...
