Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a construction method for reserving a temporary opening on a shear wall. Background Art

[0002] In residential projects, a residential building is usually composed of multiple units, with structural seismic joints between the units, and shear walls on both sides of the seismic joints belonging to different structural units. When adjacent structural units are staggered, due to the separation of the structural shear walls, adjacent units cannot form a connecting passage for material transportation or personnel walking, resulting in the division of the construction work surface, which reduces construction efficiency and increases the cost of measures for the construction personnel and freight elevators equipped separately for each structural unit.

[0003] Therefore, the present invention provides a construction method for reserving a temporary opening on a shear wall. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a construction method for reserving temporary openings on a shear wall, so as to solve the problem that the existing shear wall will cause the construction working surface to be divided, thereby reducing the construction efficiency.

[0005] The invention provides a construction method for reserving a temporary opening on a shear wall, and the technical scheme is as follows: specifically comprising the following steps: S1: arranging wall reinforcement at a designed position of a wall body; S2: arranging reserved reinforcement around the designed position of a temporary opening, so that the reserved reinforcement is located within the designed position of the wall body, and the end of the reserved reinforcement extends to the designed position of the temporary opening; S3: constructing the wall body, so that the lower side surface of the formed temporary opening is consistent with the height of the corresponding lower floor slab; S4: arranging protective pads on the left, right and upper sides of the temporary opening, and the protective pads cover the reserved reinforcement; S5: arranging an anti-slope at the lower side of the temporary opening, so that the anti-slope covers the reserved reinforcement.

[0006] Furthermore, the construction steps of the reserved reinforcement are as follows: provide a plurality of horizontal reserved reinforcements, arrange the plurality of horizontal reserved reinforcements at intervals up and down on both sides of the temporary opening design position, and horizontally sleeve the horizontal reserved reinforcements on the wall steel bars; provide a plurality of upper vertical reserved reinforcements, arrange the plurality of upper vertical reserved reinforcements at intervals left and right on the upper side of the temporary opening design position; provide a plurality of lower vertical reserved reinforcements, arrange the plurality of lower vertical reserved reinforcements at intervals left and right on the lower side of the temporary opening design position.

[0007] Furthermore, after the construction of the wall is completed, the lower vertical reserved reinforcement is extended to one end of the temporary opening, bent and fitted with the wall.

[0008] Furthermore, after the bending of the lower vertical reserved reinforcement is completed, the anti-ridge is cast so that the lower vertical reserved reinforcement is buried in the anti-ridge.

[0009] Furthermore, the protective pad is foam, through holes are opened in the foam, and when the foam is installed, the through holes in the foam are made to correspond to the corresponding horizontal reserved ribs and the upper vertical reserved ribs.

[0010] Furthermore, after the temporary opening is used up, it is sealed, and the specific sealing method is as follows: remove the foam; chisel out the anti-ridge; extend the lower vertical reserved reinforcement to one end of the temporary opening to bend and straighten it; provide a plurality of connecting steel bars, arrange the plurality of connecting steel bars in the temporary opening at intervals in the horizontal and vertical directions, and fix the connecting steel bars to the corresponding reserved reinforcements; support formwork on the front and rear sides of the temporary opening, and make the formwork fit the wall; pour concrete into the formwork.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] When pouring the shear wall, temporary openings are reserved on the wall to enable horizontal transportation of materials and movement of personnel, thereby improving work efficiency on the construction site and reducing the cost of vertical transportation equipment.

[0013] Arranging reserved reinforcement around the temporary opening and burying the reserved reinforcement in the wall can increase the structural strength of the wall around the temporary opening and reduce construction risks. It can also facilitate the arrangement of fixed reinforcement in the temporary opening when the temporary opening is blocked.

[0014] Foam is laid on the left and right sides and the upper side of the temporary opening, and a counter-slope is poured on the lower side to cover the exposed reserved reinforcement and prevent people from getting injured when passing by. BRIEF DESCRIPTION OF THE DRAWINGS
