Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a device for improving the crack resistance of the outer wall of a basement. Background Art

[0002] With the application of a large number of extra-long and extra-large basements, "diseases" such as cracks and seepage in basement structures caused by improper design, uncontrolled management, and construction often occur. Cracks in the basement exterior wall will lead to water seepage in the basement, accompanied by corrosion of the steel bars inside the wall, which will affect the use function of the building and reduce the durability and stability of the building. After the basement exterior wall cracks, the builder will invest a lot of manpower and material resources to take remedial measures, which often requires more resources and costs, and is also prone to delays in construction.

[0003] Concrete is an artificial stone made of cementitious materials, water and coarse and fine aggregates in appropriate proportions, mixed into a mixture, and hardened after a certain period of time. Experiments and engineering practice have found that the law of concrete shrinkage deformation is fast at first and then slow. During the period from initial setting to final setting after concrete pouring, the cement hydration reaction is intense, and the water evaporates rapidly, causing water loss shrinkage, accompanied by uniform shrinkage deformation between aggregates and adhesives. Both deformations occur before the final setting of concrete, that is, the plastic stage, so they are called plastic shrinkage. Excessive water-cement ratio, large amount of cement, poor water retention of admixtures, small amount of coarse aggregate and large amount of water, poor vibration, high ambient temperature, large surface water loss, etc. are all causes of plastic shrinkage surface cracking. Plastic shrinkage develops along the surface of the steel bar, which will cause steel bar corrosion and affect the durability of the structure, causing cracks in the side wall of the basement.

[0004] Due to the structural position and stress characteristics of the basement wall, the concrete used for the basement exterior wall is generally high in strength and mostly uses commercial concrete with high fluidity and high slump, so the temperature deformation and shrinkage deformation during the construction process are relatively large. The wall panel is a vertical structure, which is more difficult to maintain. In addition, the plane size of the basement exterior wall is different from that of general large-volume concrete, which makes the wall panel subject to greater constraints from the foundation. Under the premise of not changing the concrete strength, gradation, pouring method and technical level of the construction personnel, strengthening the crack resistance, tensile and compressive resistance of the internal steel bars of the wall and designing a new type of anti-cracking device can effectively enhance the crack resistance of the basement exterior wall.

A hook 2 is provided at the upper and lower ends of each vertical steel pipe 1, which is used to hang the vertical steel pipe 1 on the steel cage of the basement exterior wall. The exterior wall anti-cracking device 3 comprises a cylinder 16, an elastic member is provided on the outside of the cylinder 16, a piston rod 10 is sleeved inside the cylinder 16, a first disc 9 is fixedly connected to the end of the cylinder 16, the first disc 9 is fixedly connected to the end of the piston rod 10, and a buffer is provided inside the cylinder 16.

The cooperation of the wedge block and the latch 14 facilitates the disassembly of the connection and the replacement of the external wall anti-cracking device 3.

[0033] Reference Figure 1 , Figure 3 A transverse steel pipe 6 is also arranged between the two vertical steel pipes 1, and both ends of the transverse steel pipe 6 are respectively fixedly connected to the two vertical steel pipes 1, and the transverse steel pipe 6 is fixedly connected to the tensile hanging device 5, and a hook 2 is arranged at one end of the tensile hanging device 5 away from the transverse steel pipe 6. When the construction location is narrow, the tensile hanging device 5 is provided with a hook 2, so that the device as a whole can be hung on the external wall steel cage.

[0034] Reference Figure 3 , Figure 4 The tensile hanging device 5 includes a cylinder 16, an elastic member is arranged on the outside of the cylinder 16, a piston rod 10 is sleeved inside the cylinder 16, a first disc 9 is fixedly connected to the end of the cylinder 16, the first disc 9 is fixedly connected to the end of the piston rod 10, and a buffer is arranged inside the cylinder 16.

[0035] Reference Figure 1 , Figure 4 , Figure 6 , Figure 7 The piston rod 10 is telescopically connected to the sleeve rod 12. The sleeve rod 12 is sleeved with a sleeve 15 at one end away from the piston rod 10. The end of the sleeve 15 is fixedly connected to a second disc. The end of the elastic member away from the first disc 9 is fixedly connected to the second disc 11.

[0036] Reference Figure 4 , Figure 7 The buffer is a rubber buffer tube, and the buffer is arranged in the inner layer of the sleeve 15.

[0037] Reference Figure 4 , Figure 7 , the elastic member is a spring 8.

[0038] Reference Figure 1 , multiple external wall anti-cracking devices 3 are set, and multiple tensile hanging devices 5 are set, which helps to better improve the cracking of the basement external wall.

[0039] When in use, the device is hung outside the wall reinforcement cage, and then the wall is poured. The device can increase the overall strength of the reinforcement cage, thereby reducing wall cracking. When the outer wall of the basement is subjected to external force, the spring 8 produces adaptive deformation, and the piston rod 10 and the sleeve rod 12 expand and contract adaptively. When the external force is large, the sleeve rod 12 and the sleeve 15 will slide relative to each other, and the rubber buffer tube in the sleeve 15 has a large friction resistance, which plays a buffering role on the movement of the sleeve rod 12. As a result, the force on the reinforcement cage to which the device is attached is buffered and shock-absorbing, thereby reducing the possibility of cracking of the wall due to deformation of the reinforcement cage.

The structure is simple and can meet the requirements of external wall anti-cracking. The overall structure of the device is light and compact, and the hook style can be adjusted to attach it to the steel mesh of the basement external wall, reducing the subsequent concrete pouring amount and reducing construction costs.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
