Abstract

The invention provides a short-leg masonry shear wall structure with reinforced blocks. It is composed of reserved anchor bars set on the foundation or floor, walls made of concrete hollow blocks and poured with core concrete, and concrete connecting beams. The thickness ratio of the wall limbs is controlled at 5-8. Assembling an integral load-bearing wall structure, horizontal steel bars are set in the horizontal grooves of the concrete blocks and in the horizontal mortar joints, vertical steel bars are set in the holes of the concrete blocks, and the horizontal bars and vertical bars form a vertical and horizontal steel mesh , and pouring core concrete in vertical holes and horizontal grooves. The invention has the advantages of fast construction speed, saving steel bars, no formwork, and saving engineering costs, while avoiding the occurrence of material shrinkage cracks and temperature cracks on the structure, and greatly improving the safety performance and earthquake resistance of the structure.

Description

Reinforced block short leg masonry shear wall structure

1. Technical field

The invention relates to a bearing wall structure of a building.

2. Background technology

With the implementation of the national strategy of reducing energy consumption and sustainable development, the use of clay solid bricks for load-bearing in buildings has been banned on a large scale. As an alternative building material, concrete hollow blocks have become the focus of future development, but ordinary concrete blocks The crack problem and cost problem of the body became the obvious disadvantage of replacing the clay solid brick wall, and was once resisted by the builder. Under such circumstances, the development of a new type of load-bearing system to fundamentally solve the problems of cracks and construction costs has become a key structural technology that needs to be solved urgently.

3. Contents of the invention

The object of the present invention is to provide a short-leg masonry shear wall structure with reinforced blocks, which has fast construction speed, saves steel bars, does not need templates, saves engineering costs, and can avoid material shrinkage cracks and temperature cracks in the structure.

The object of the present invention is achieved like this: it is made up of the reserved anchor bar that is arranged on the foundation or the slab, the wall that is built with concrete hollow blocks and pours the core concrete and the concrete connecting beam, the limb of the wall Assembled integral load-bearing wall structure with a thickness ratio of 5 to 8, horizontal steel bars are arranged in the horizontal grooves of the concrete blocks and the horizontal mortar joints, and vertical steel bars, transverse bars and The vertical reinforcement forms a vertical and horizontal reinforcement mesh, and pours core concrete in the vertical holes and horizontal grooves.

The present invention can also include such structural features:

1. Pouring core concrete in the hole.

2. The concrete connecting beams are equipped with steel bars connected with the wall reinforcement mesh.

3. The concrete hollow block is a double-hole block with a porosity not lower than 40%.

4. The wall is a wall with a thickness ratio of 5-8.

5. The cross-sectional shape of the wall can be "one", "T", "L" or "ten".

The present invention combines the masonry construction characteristics of block masonry with the construction characteristics of cast-in-place concrete to form a load-bearing member of a short-leg masonry shear wall with reinforced blocks, which is combined with a reinforced concrete floor to form a new load-bearing structure system. It has created a brand-new new structural system for the construction of multi-storey and small high-rise buildings. The remarkable feature of this system is that the walls are built with double-hole blocks with a porosity of not less than 40%, and the reinforcement and Pour concrete to form an assembled monolithic wall with a limb thickness ratio between 5 and 8, and its cross-sectional shape can be "one", "T", "L", "ten", etc. shape. The invention has the advantages of fast construction speed, saving steel bars, no formwork, and saving engineering costs, while avoiding the occurrence of material shrinkage cracks and temperature cracks on the structure, and greatly improving the safety performance and earthquake resistance of the structure.

4. Description of drawings

Accompanying drawing is wall reinforcement and structural representation of the present invention.

5. Specific implementation

The present invention is described in more detail below in conjunction with accompanying drawing example:

The short-leg masonry shear wall structure with reinforced blocks consists of anchor bars 1 reserved on the foundation or floor, walls 2 made of masonry concrete hollow blocks, and concrete connecting beams 3. Horizontal steel bars 4 are arranged in the horizontal grooves and horizontal mortar joints, vertical steel bars 5 are arranged in the concrete block holes, and the horizontal bars and vertical bars are connected to each other to form a vertical and horizontal steel mesh. A special core-filling concrete is poured in the hole. Reinforcement bars connected with the wall reinforcement mesh are arranged in the concrete connecting beams. The concrete hollow block is a double-hole block with a porosity not lower than 40%. The wall body is a wall body with limb thickness ratio between 5-8. The cross-sectional shape of the wall can be "one", "T", "L" or "ten".

The construction sequence of the present invention is: 1. Reserve anchor bars on the foundation or floor; 2. Build concrete hollow block walls, and set horizontal steel bars in horizontal grooves and horizontal mortar joints at the same time; 3. Place vertical 4. Pour special core concrete in the hole; 5. Install the coupling beam and ring beam formwork, bind the steel bars, and pour concrete; 6. Remove the formwork to form the reinforced block short-leg masonry shears The force system of the force wall structure.
