Problems solved by technology

Although this kind of crack will not endanger the safety of the engineering structure, it will affect the appearance, give the user a feeling of insecurity, and seriously cause the leakage of the board seam, which will affect the use function of the house.
Aiming at the problem of cracks, the method of punching an oblique hole passing through the joint with a percussion drill is usually used to drive the steel needle. Although it can play a certain role, this method is due to the lack of elastic tension, pressure and compensation. Yes, the effect is not ideal
There is also the method of nailing the screen at the joints and painting with sealant. This solution is complicated to construct, and only the screen is arranged on the surface, and there is no compensation for deformation energy storage. It is difficult to solve the essential problem of preventing material shrinkage and cracking.

Embodiment 1

[0043] Take two prefabricated wall panels with convex and concave tenons that can effectively prevent cracking, match the convex and concave tenon joints 11 of the left and right two wall panels and make the corresponding windows 2 face each other to complete the assembly of the wall panels; then use wire cutters or crowbars After the elastic deformation section 32 of the tension spring 3 of the prefabricated wall panel is changed from an acute angle to a right angle by means of external force, the locking piece 4 is pressed in so that the locking section 43 and the locking section 33 of the tension spring 3 are elastically fastened; The window 2 and / or the tenon and tenon joint 11 after the spring is locked are filled with glass wool, and then the window 2 and the tenon and tenon joint 11 are painted with common leveling agent, and finally the prefabricated wallboard joint is completed by scraping. construction.

Embodiment 2

[0045] Take two prefabricated wall panels whose flat ends can effectively prevent cracking, align the end faces of the left and right two wall panels and make the corresponding windows 2 face each other to complete the assembly of the wall panels; then use wire cutters or crowbars to make the prefabricated wall panels After the elastic deformation section 32 of the tension spring 3 changes from an acute angle to a right angle, tighten the locking section 33 corresponding to the left and right tension spring 3 with iron wire to achieve the purpose of locking the tension spring 3; after the spring is locked, the window 2 and / or Or fill the mixture of rock wool and styrofoam in the gaps of the butt joint ends, then use common leveling agent to paint the window 2 and the gaps of the butt joint ends, and finally scrape white to complete the construction of the prefabricated wallboard joints.

Embodiment 3

[0047] Take two prefabricated wall panels with convex and concave tenons that can effectively prevent cracking, match the convex and concave tenon joints 11 of the left and right two wall panels and make the corresponding windows 2 face each other to complete the assembly of the wall panels; then use wire cutters or crowbars After the elastic deformation section 32 of the tension spring 3 of the prefabricated wallboard is changed from an acute angle to a right angle by means of external force, the locking section 33 of the left and right corresponding tension spring 3 is fixedly connected by electric welding to achieve the purpose of locking the tension spring 3; Fill the locked window 2 and / or the tenon-and-tenon joint 11 with an appropriate amount of common anti-crack mortar, then use common leveling agent to paint the window 2 and the tenon-and-tenon joint 11, and finally scrape white to complete the prefabricated wallboard Construction of seams.

Abstract

The invention discloses a prefabricated panel capable of effectively preventing cracking and a cracking-preventing construction method thereof. The prefabricated panel comprises a panel body (1), wherein a window (2) with an opening in the end face is formed in at least one end of the panel body (1) and is internally provided with tension springs (3) with one end fixedly connected with the panel body (1). The cracking-preventing construction method comprises the steps of splicing the panel, locking the springs and filling and troweling. According to the prefabricated panel, the tension springs are fixedly arranged in the windows in the end faces of the prefabricated panel, and the influence on a joining seam of the prefabricated panel caused by an external force or a climatic factor can be reduced and resisted by using elastic tensile forces and energy storage after the tension springs of two adjacent and same prefabricated panels are locked, thus the prefabricated panel can bear high stress and deformation, and the cracking probability of the joining seam is reduced. The prefabricated panel disclosed by the invention is simple in structure and convenient to install, and brings the convenience to factorized volume production. According to the cracking-preventing construction method, the process is simple, the cracking-preventing effect is remarkable, and the local workload can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a prefabricated wallboard capable of effectively preventing cracking, which is simple in structure, convenient for installation and convenient for factory batch production, and a cracking prevention construction method thereof. Background technique [0002] At present, most of the materials used for building walls in my country are hollow clay bricks. On-site wet operation will bring a series of adverse effects such as excessive structural weight, slow construction speed, low work efficiency, and reduced effective building area. For this reason, various new energy-saving building materials and new residential structure systems have been developed in recent years. Prefabricated wall panels have the advantages of light weight, convenient construction, short construction period, energy saving and environmental protection, and prefabricated hollow panels are use...
