Description

A formwork-free self-insulating brick wall construction method

technical field

The invention relates to the technical field of building construction, in particular to a formwork-free self-insulating brick wall construction method.

Background technique

With the vigorous development of my country's infrastructure and the comprehensive promotion of green design, building energy conservation plays an important role in green design. Compared with traditional masonry bricks, self-insulating sintered bricks can effectively reduce the internal heat transfer of the wall and improve the thermal insulation performance of the wall.

In the process of traditional thermal insulation brick masonry, the construction sequence: laying out → planting reinforcement → row of bricks with vertical bars → waist beam construction → wall masonry above the waist beam → structural column construction → horizontal plug top → insulation board pasting → plastering overlay. The construction of traditional waist beams and structural columns requires the pouring of concrete after setting up the formwork. The construction process is complicated, the progress of the construction period is slow, and the forming effect is poor. The small wooden squares and small formworks produced by sawing do not meet the requirements of green construction. At the same time, after the insulation board is pasted on the cold bridge, the insulation board protrudes from the facade of the wall, resulting in an excessively thick wall plaster layer, difficult to control the construction quality, and easy to cause hollowing, cracking and other phenomena.

Contents of the invention

The purpose of the present invention is to provide a self-insulation brick wall construction method free of formwork, to solve the traditional insulation brick masonry construction method mentioned in the above-mentioned background technology, it is necessary to formwork on cold bridge positions such as waist beams and structural columns After the concrete is poured, the insulation board is pasted. The insulation board protrudes from the wall elevation, resulting in an excessively thick wall plaster layer, difficult to control the construction quality, and easy to cause problems such as hollowing and cracking.

In order to achieve the above object, the present invention provides the following technical solutions: a formwork-free self-insulating brick wall construction method, comprising the following steps:

(1) Play the main axis of the building and the masonry control sideline of the masonry according to the drawings, and plant reinforcement at the position where the structural column is set according to the requirements of the specification;

(2) On the outer wall or where there is a waterproof requirement, pour a plain concrete flanging with a height of 150mm-250mm. The width of the plain concrete flanging is the thickness of the wall minus the thickness of the insulation board, and the plain concrete flanging The inner wall of the wall is flush with the inner wall surface of the wall;

(3) Arrange bricks on the wall with a number rod, and plant reinforcement at the position of the waist beam;

(4) Masonry starts from the insulation wall below the waist beam;

(5) The waist beam is built with U-shaped bricks and the steel bars are arranged, and the width of the U-shaped bricks is the thickness of the wall minus the thickness of the insulation board, and the inner wall of the U-shaped bricks is flush with the inner wall of the wall;

(6) Pouring waist beam concrete;

(7) After the concrete strength of the waist beam meets the requirements, start to build the self-insulation wall above the waist beam, and use U-shaped bricks to build the outer frame of the structural column;

(8) After the wall masonry is completed, pour the structural column concrete. The width of the structural column concrete is the thickness of the wall minus the thickness of the insulation board, and the inner wall of the structural column concrete is flush with the inner wall surface of the wall;

(9) After 14 days, carry out horizontal plugging on the top of the wall;

(10) After the insulation board is pasted, the outer wall of the pasted insulation board is flush with the outer wall of the wall;

(11) Carry out plastering and overlay construction.

Further, the plain concrete flanging is constructed by pouring concrete of the same grade as the floor concrete.

Further, the insulation board is fixedly connected to the wall through anchors.

Further, the wall is built with gangue bricks.

Compared with prior art, the beneficial effect of the present invention is:

(1) During the masonry process of insulation bricks, reserve the installation space for the insulation board at the part where the insulation board needs to be pasted, so that after the insulation board is installed on the cold bridge, it can be kept flush with the outer wall of the wall, which is convenient for later installation. The wall is painted to reduce the problems of hollowing and cracking;

(2) The present invention greatly improves the molding quality, improves work efficiency, and shortens the construction period; at the same time, it also reduces the consumption of plates and wood, fully realizes green construction, and brings great economic benefits.
