Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a wall reinforcement structure that resists dry-wet cycles and prevents cracking. Background Technology
[0002] Walls are important components in buildings that serve to bear loads, enclose, or divide space. They are classified into load-bearing walls and non-load-bearing walls according to their load-bearing capacity, and into brick walls, aerated concrete block walls, stone walls, etc., according to their materials. The thickness can be divided into 115mm half-brick walls and 240mm one-brick walls according to the standard clay brick specifications. Their design must meet the requirements of load-bearing capacity, stability, and performance such as thermal insulation, heat insulation, sound insulation, and fire resistance. The structural scheme covers the load-bearing system of transverse or longitudinal walls, and the detailed construction includes components such as lintels, window sills, and moisture-proof courses.
[0003] During the construction of the wall, the existing technology usually involves pouring a 30cm high waterproof concrete beam on the foundation to block ground moisture. Although the tie bar technology is used, the stability between the newly built wall and the concrete beam is still not strong enough. At the same time, the joint between the newly built wall and the concrete beam is prone to cracking with changes in temperature or humidity. Utility Model Content
[0004] In order to solve the above problems, the purpose of this utility model is to provide a wall reinforcement structure that resists dry and wet cycles and prevents cracking.
[0005] To solve the above technical problems, the present invention adopts the following technical solution: a wall anti-dry-wet cycle anti-cracking reinforcement structure, including a ground beam, the ground beam being made of concrete, reinforcement components being provided on the upper and lower surfaces of the ground beam, and anti-cracking components being provided on both sides of the ground beam;
[0006] The reinforcement components include steel bars, No. 1 bricks and No. 2 bricks. A number of steel bars are provided and are distributed at equal intervals on the upper and lower surfaces of the ground beam. A number of No. 1 bricks and No. 2 bricks are provided and are laid on the upper and lower surfaces of the ground beam. The No. 1 bricks and No. 2 bricks are laid in a cross pattern.
[0007] The anti-cracking component includes two grooves, which are symmetrically arranged on both sides of the ground beam. A wire mesh is installed inside the groove. A mortar layer is applied to the outer side of the wire mesh. A mesh cloth is pasted to the outer side of the mortar layer. A putty layer is applied to the outer side of the mesh cloth.
[0008] Both sides of the ground beam are coated with a waterproof layer, which is formed by applying a flexible waterproof coating.
[0009] The No. 1 and No. 2 bricks include either clay bricks or cement bricks.
[0010] The putty layer is formed by applying high-elasticity putty with an elongation rate of ≥200%.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1: As Figure 1-5 As shown, this utility model provides a wall anti-dry-wet cycle crack-prevention reinforcement structure, including a ground beam 1, which is made of concrete. Both sides of the ground beam 1 are coated with a waterproof layer, which is formed by flexible waterproof coating. Reinforcement components 2 are set on the upper and lower surfaces of the ground beam 1. By setting reinforcement components 2, after the ground beam 1 is poured on the upper surface of the foundation 10, the reinforcement components 2 can improve the stability between the ground beam 1 and the foundation 10. At the same time, the waterproof layer can improve the waterproof performance of the ground beam 1 and prevent rainwater from seeping in. When a partition wall 20 is built on the upper surface of the ground beam 1, the reinforcement components 2 can improve the stability between the partition wall 20 and the ground beam 1, thereby improving the stability of the partition wall 20. When building the partition wall 20, grooves 30 are reserved on both sides of the bottom of the partition wall 20, which correspond to grooves 31. Anti-cracking components 3 are set on both sides of the ground beam 1. By setting anti-cracking components 3, cracking at the joint between the partition wall 20 and the ground beam 1 can be prevented.
[0024] The reinforcement component 2 includes steel bars 21, first bricks 22, and second bricks 23. Several steel bars 21 are set and are evenly distributed on the upper and lower surfaces of the ground beam 1. Several first bricks 22 and second bricks 23 are set and are built on the upper and lower surfaces of the ground beam 1. The first bricks 22 and second bricks 23 are laid crosswise. The first bricks 22 and second bricks 23 are made of clay bricks. By setting steel bars 21, first bricks 22, and second bricks 23 on the upper and lower surfaces of the ground beam 1, the steel bars 21 can improve the stability between the ground beam 1 and the foundation 10, and at the same time improve the stability between the partition wall 20 and the ground beam 1. The first bricks 22 and second bricks 23 are made of clay bricks and are laid crosswise. Clay bricks are suitable for load-bearing walls and have high compressive strength.
[0025] The anti-cracking component 3 includes two grooves 31, which are symmetrically arranged on both sides of the ground beam 1. A wire mesh 32 is installed inside each groove 31. The wire mesh 32 is made of steel plate mesh, which has high strength and can be independently nailed for plastering. A mortar layer 33 is applied to the outer side of the wire mesh 32, and a mesh fabric 34 is adhered to the outer side of the mortar layer 33. A putty layer 35 is applied to the outer side of the mesh fabric 34. The putty layer 35 is formed using high-elasticity putty with an elongation rate ≥200%. The putty layer 35 can absorb the stress generated by temperature and humidity changes or external forces on the partition wall 20 and the ground beam 1, thereby reducing the risk of cracking. The wire mesh 32, mortar layer 33, mesh fabric 34, and putty layer 35 extend into the groove 30 to provide anti-cracking treatment at the joint between the partition wall 20 and the ground beam 1.
[0026] Example 2: Unlike Example 1, brick 22 and brick 23 are made of cement bricks. Cement bricks have a Mohs hardness of 6 to 7 and high compressive strength. The wire mesh 32 is made of galvanized wire mesh. Due to the zinc immersion treatment on the surface of the galvanized wire mesh, it has strong corrosion resistance and is suitable for use in humid and corrosive environments.
[0027] Example 3 differs from Examples 1 and 2 in that the wire mesh 32 is made of stainless steel wire mesh, and the stainless steel wire mesh is made of 316 stainless steel wire, which has the characteristics of high temperature resistance and corrosion resistance, thus avoiding rust in humid environments.
[0028] Working principle: Concrete is poured into the mold, and steel bars 21 are embedded in it. After the concrete solidifies and is demolded, a ground beam 1 is formed. At the same time, multiple intersecting No. 1 bricks 22 and No. 2 bricks 23 are laid on the lower surface of the ground beam 1 by masonry.
[0029] The ground beam 1 is fixed to the foundation 10 by mortar. A gap is reserved in the foundation 10 in advance for the steel bar 21, the first brick 22 and the second brick 23 to enter. After the mortar is poured and solidified, the ground beam 1 can be fixed to the foundation 10.
[0030] Subsequently, following the steps described above, brick 22 and brick 23 are laid on the upper surface of the ground beam 1. Then, a partition wall 20 is built on the upper surface of the ground beam 1, and grooves 30 are reserved on both sides of the bottom end of the partition wall 20.
[0031] After the partition wall 20 is stabilized, plaster is applied inside the groove 30, and the wire mesh 32 is fixed in the groove 31 and the groove 30 with nails. A mortar layer 33 is applied to the outside of the wire mesh 32. After the mortar layer 33 has solidified and dried, the mesh cloth 34 is fixed in the groove 31 and the groove 30 with glue. Then, a putty layer 35 is applied to the outside of the mesh cloth 34 to prevent cracking at the joint between the partition wall 20 and the ground beam 1.
[0032] After the entire structure has solidified and dried, apply waterproofing between ground beam 1 and foundation 10, and between partition wall 20 and ground beam 1 to form a waterproof layer.
[0033] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
