Description

Technical Field

[0001] The present invention relates to the field of building construction, and specifically to a method for masonry wall construction on both sides of the deformation joint position. Background Art

[0002] During the construction of building projects, there are various types of deformation joints, and masonry walls are used for filling and partitioning on both sides of the deformation joints. However, due to the small space of the deformation joint and the presence of structural beams on both sides of the deformation joint, it will cause problems that the walls and construction columns at the positions on both sides of the deformation joint cannot be constructed in the structural beam area. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above defects and propose a method for masonry wall construction on both sides of the deformation joint position, so as to solve the problem that the masonry walls on both sides of the deformation joint cannot be constructed, and achieve the purpose that the masonry walls play their due building functions.

[0004] To achieve the above purpose, the present invention is implemented as follows:

[0005] A method for masonry wall construction on both sides of the deformation joint position, characterized by including

[0006] Step 1: Drill holes and insert reinforcement bars at the bottom of the beam to make a cantilever slab, and the length of the cantilever slab is the same as the top;

[0007] Step 2: Chisel the interface between the new and old concretes, chisel and clean, and apply neat cement slurry;

[0008] Step 3: Make a formwork support system at the cantilever slab;

[0009] Step 4: Pour the concrete of the cantilever slab, and the strength grade is one strength grade higher than that of the beam concrete;

[0010] Step 5: Use a small concrete pump hose to pour the concrete from the deformation joint, use fine aggregate concrete for pumping, and vibrate manually;

[0011] Step 6: When the strength of the cantilever slab reaches the formwork removal requirement, remove the formwork support system;

[0012] Step 7: First, masonry one side of the masonry wall to the bottom of the ring beam, and pour the construction column and the ring beam below the ring beam;

[0013] Step 8: Then, masonry the other wall to the bottom of the ring beam, and pour the construction column and the ring beam below the ring beam;

[0014] Step 9: Masonry the first wall to the position of the cantilever slab, pour the construction column, and use small bricks for capping later;

[0015] Step 10: Then build another wall up to the cantilever slab position, support the formwork of the construction column, and pour the construction column. The formwork of the construction column is reinforced in a way that it will not be removed later;

[0016] Among them,

[0017] The length of the planted bars is not less than 300 mm, and Class A bonding adhesive for planted bars is used;

[0018] The interface between the new and old concretes is chiseled and cleaned, and an interface agent is applied.

[0019] By adopting the above construction method, compared with the traditional construction plan, the cantilever slab at the lower part of the beam is added, and concrete pouring is carried out at the same time. In this way, the strength of the deformation joint is ensured, enabling it to achieve the designed function and overcoming the problem that construction cannot be carried out due to the narrow space inside the deformation joint gap in the traditional construction method.

[0023] The present invention is further illustrated by the following specific embodiments.

[0024] As Figure 1 shown, a masonry wall construction method on both sides of the deformation joint position includes

[0025] Step 1: Conduct bar planting at the bottom of the beam to make a cantilever slab, and the length of the cantilever slab is the same as that at the top; (As Figure 2 )

[0026] Step 2: Conduct chiseling treatment on the interface between the new and old concretes, chisel and clean, and apply pure cement slurry;

[0027] Step 3: Make a formwork support system at the cantilever slab position (As Figure 3 )

[0028] Step 4: Pour the concrete of the cantilever slab, and the strength grade is increased by one grade compared with the beam concrete;

[0029] Step 5: When pouring the concrete, use a small ground pump hose to pour from the deformation joint, adopt fine aggregate concrete for pumping, and vibrate manually;

[0030] Step 6: When the strength of the cantilever slab reaches the form removal requirement, remove the formwork support system;

[0031] Step 7: First, build one side of the masonry wall up to the bottom of the ring beam, and pour the construction columns and the ring beam below the ring beam.

[0034] Step 10: Build the other wall up to the position of the cantilever slab, support the formwork of the construction column, and pour the construction column. The formwork of the construction column is reinforced in a way that it will not be removed later.

[0035] Among them,

[0036] The length of the implanted steel bars is not less than 300 mm, and Class A implanting adhesive is used.

In this way, the strength of the deformation joint is ensured, enabling it to achieve the designed function and overcoming the problem that it is impossible to construct due to the narrow space inside the deformation joint gap in the traditional construction method.
