Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically to a crack-resistant wall and its construction method. Background Technology

[0002] Wall cracking is a common quality problem in the construction industry. Its causes include material shrinkage and deformation, temperature stress changes, improper construction techniques, and unreasonable structural design. Wall cracking not only reduces the building's impermeability and overall stability, but may also cause local stress concentration leading to structural failure, and even affect the building's service life and safety. To address this problem, it is necessary to reduce the possibility of crack formation from the source by optimizing material performance, improving construction techniques, and strengthening structural design. At the same time, scientific testing and repair techniques should be adopted to extend the building's service life.

[0003] Existing non-load-bearing walls are generally constructed using traditional masonry or plastering techniques, resulting in low structural strength and insufficient crack resistance. They are prone to localized cracking or even through-cracks, especially under alternating temperature and humidity changes or external loads. Although some construction methods attempt to improve wall performance by adding steel mesh or adjusting mortar mix ratios, these methods are limited by material properties and construction precision, making it difficult to fundamentally solve the cracking problem. Therefore, there is an urgent need to develop a new type of wall structure and its construction method, which can effectively control and prevent wall cracks by optimizing material combinations, enhancing interfacial bonding, and introducing flexible crack-resistant components.

[0004] A Chinese invention patent with publication number CN111305410B discloses a crack-resistant wall and its construction method. The key technical points are: a main wall, several interior panels, a plaster layer, several vertical and horizontal keels, connecting components, and fixing components; the construction method includes: a. measuring and setting out; b. installing fixing plates; c. installing connecting plates; d. installing vertical keels; e. installing horizontal keels; f. installing interior panels; g. installing crossbeams; h. grouting. When the wall deforms, the connecting pieces used to connect the interior panels to the wall can displace on the wall surface. This displacement of the connecting pieces prevents the stress generated by the deformation from being transmitted to the wall panels, thus preventing deformation of the wall panels and the plaster layer on the wall panel surface, and thus minimizing impact on the aesthetics of the interior finish.

[0005] However, the above technologies often have the following drawbacks: the wall structure of existing technologies is too complex, making construction on non-load-bearing walls too difficult, increasing labor and material costs, and the complex structure can lead to excessive wall weight, making it difficult to demolish. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a crack-resistant wall and its construction method to solve the problems existing in the background art.

[0007] The present invention provides the following technical solution: a crack-resistant wall, a frame assembly, and further includes a connecting assembly fixedly connected to the frame assembly; a gap assembly fixedly connected to the frame assembly; and a compensation assembly fixedly connected to the frame assembly; The frame component, gap component, and compensation component together form a panel module. Multiple panel modules are fixedly connected by connecting components, and the number of connecting components is several. Preferably, the frame assembly includes an extension plate, a frame plate fixedly connected to the extension plate, an edge expansion hole on the extension plate, a corner expansion hole on the extension plate, a long slot on the frame plate, a compensation hole on the frame plate, and a grooved plate fixedly connected to the frame plate.

[0008] Preferably, the connection assembly includes a central block fixedly connected to the expansion plate, mounting holes formed on the central block, corner blocks fixedly connected to the four corners of the expansion plate, and calibration slots formed on the corner blocks.

[0009] Preferably, the central blocks are installed at positions other than the four corners around the circumference of the expansion board, and there are several of them; the corner blocks are installed at the four corners around the circumference of the expansion board, and there are several of them.

[0010] Preferably, after the two panel modules are assembled, cement mortar is injected into the cavity formed at the junction.

[0011] Preferably, the gap assembly includes a long bolt slidably connected in the long groove, a washer sleeved on the long bolt, a multi-strand steel wire rope fixedly connected to the long bolt, and bricks disposed on the inner side of the groove plate.

[0012] Preferably, there are several long bolts in the long groove, the bricks and multiple strands of steel wire rope are placed alternately, and the spaces between the bricks are filled with cement mortar.

[0013] Preferably, the compensation component includes a reinforcing beam fixedly connected to the frame plate, an internal threaded hole opened on the reinforcing beam, a through groove opened on the reinforcing beam, an elastic compensation member fixedly connected to the reinforcing beam, and a push plate fixedly connected to the elastic compensation member.

[0014] Preferably, a construction method for a crack-resistant wall includes the following steps: S1: After welding the frame components in the factory, install the compensation components with bolts, and then plan the installation position of the gap components according to the required brick size. Then lay a film or board at the bottom of the frame components to separate the ground and cement mortar. After all the components are installed, lay bricks in the area enclosed by the frame plate and the groove plate of the frame components. S2: After the bricks are laid, pour cement mortar into the gaps between the bricks and use a vibrator to remove air bubbles to ensure that the cement mortar in the gaps between the bricks is completely filled. S3: After the cement mortar has hardened, the formed panels are transported to the construction site and connected using connecting components as needed. Cement mortar is then poured between the installed frame components to form a whole and increase the overall strength.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention uses long bolts and multi-strand steel wire ropes installed in the long grooves of the frame assembly to compensate for stress through the elastic compensating components and push plates of the compensation assembly. This transfers the stress on the bricks in the horizontal or vertical direction, so that the stress does not act directly on the bricks and cement mortar, reducing wall cracking. At the same time, the groove plate constrains the bricks, and cement is filled between the bricks, the groove plate, and the frame plate to form a cement profile composite structure, increasing the strength of the wall.

[0016] 2. The present invention comprises a panel module consisting of a frame component, a gap component, and a compensation component. The panel module can be assembled and produced in the factory as needed, and then brought to the construction site for assembly and installation via connecting components, saving manpower and resources and shortening the construction period.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The anti-cracking wall and its construction method involved in the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1-4 The present invention provides a crack-resistant wall, including a frame assembly 1, a connecting assembly 2 fixedly connected to the frame assembly 1, a gap assembly 3 fixedly connected to the frame assembly 1, and a compensation assembly 4 fixedly connected to the frame assembly 1; The frame component 1, the gap component 3, and the compensation component 4 form a panel module. Multiple panel modules are fixedly connected by a connecting component 2, and the number of connecting components 2 is several.

[0021] The frame assembly 1 includes an expansion plate 11, a frame plate 12 fixedly connected to the expansion plate 11, an edge expansion hole 13 opened on the expansion plate 11, a corner expansion hole 14 opened on the expansion plate 11, a long groove 15 opened on the frame plate 12, a compensation hole 16 opened on the frame plate 12, and a slotted plate 17 fixedly connected to the frame plate 12.

[0022] The connecting component 2 includes a central block 21 fixedly connected to the expansion plate 11, mounting holes 22 formed on the central block 21, corner blocks 23 fixedly connected to the four corners of the expansion plate 11, and calibration slots 24 formed on the corner blocks 23.

[0023] The central block 21 is installed around the perimeter of the expansion plate 11, except for the four corners, and there is a certain number of such blocks. The corner blocks 23 are installed around the four corners of the expansion plate 11 and there is a certain number of such blocks.

[0024] After the two panel modules are assembled, cement mortar is injected into the cavity formed at the junction.

[0025] Specifically, the frame component 1 is the core component of the entire panel module. The frame component 1 is made of steel plate. The expansion plate 11 has many edge expansion holes 13 and corner expansion holes 14 to facilitate the installation and docking between modules. The frame plate 12 has bricks 34, gap components 3 and compensation components 4 installed inside. The frame plate 12 has compensation holes 16 to facilitate the installation of compensation components 4.

[0026] The middle block 21 of the connecting component 2 is specifically used to install the middle position of the expansion plate 11. The mounting holes 22 on the middle block 21 and the edge expansion holes 13 are installed with bolts. The corner block 23 is used for the fixed installation of the corner position of the expansion plate 11. Since there are multiple installation combinations in the corner position of the expansion plate 11, the number of mounting holes 22 opened on the corner block 23 is significantly more than that on the middle block 21. The calibration groove 24 is used for the calibration and limiting function of the corner block 23 on the expansion plate 11.

[0027] Through the connecting component 2, a strong connection can be formed between the expansion plates 11. At the same time, the connection process is quick and can be prefabricated in the factory and transported to the construction site for assembly, saving manpower and material resources. After the expansion plates 11 are extended and installed, the gaps can be filled with cement mortar, which forms a cement profile composite structure while filling the gaps, thereby enhancing the structural strength.

[0028] Reference Figure 5-10 The gap assembly 3 includes a long bolt 31 that is slidably connected in the long groove 15, a washer 32 that is sleeved on the long bolt 31, a multi-strand steel wire rope 33 that is fixedly connected to the long bolt 31, and a brick 34 that is set inside the groove plate 17.

[0029] A number of long bolts 31 are placed in the long groove 15, and bricks 34 and multiple strands of steel wire rope 33 are placed alternately, with cement mortar filling the gaps between the bricks 34.

[0030] The compensation component 4 includes a reinforcing beam 41 fixedly connected to the frame plate 12, an internal threaded hole 42 opened on the reinforcing beam 41, a through groove 43 opened on the reinforcing beam 41, an elastic compensation member 44 fixedly connected to the reinforcing beam 41, and a push plate 45 fixedly connected to the elastic compensation member 44.

[0031] Specifically, the long bolts 31 are installed in the long grooves 15, and their number and spacing can be adjusted according to the size of the bricks 34. Multiple strands of steel wire ropes 33 are fixedly connected to the long bolts 31. The multiple strands of steel wire ropes 33 are embedded between the bricks 34, and the gaps between the bricks 34 are filled with cement mortar. After the cement mortar hardens, the multiple strands of steel wire ropes 33 maintain the spacing between the bricks 34 and can form a reinforced concrete structure with the cement mortar. When the bricks 34 are subjected to stress, the stress will be distributed by the multiple strands of steel wire ropes 33, reducing the direct stress on the bricks 34 and the cement mortar, which may cause cracking.

[0032] While the multi-strand steel wire rope 33 shares the stress, the reinforcing beam 41 is fixedly connected to the frame plate 12 through the internal threaded hole 42. The multi-strand steel wire rope 33 passes through the through groove 43. When the brick 34 is subjected to stress parallel to the direction of the multi-strand steel wire rope 33, the stress is offset by the elastic compensation member 44. The push plate 45 expands the effective area and reduces the stress on the individual brick 34.

[0033] With the combined action of the compensation component 4 and the gap component 3, the stresses on the brick 34 in different directions will be borne or shared by the gap component 3 or the compensation component 4, reducing the possibility of wall opening.

[0034] Example 3, referring to Figure 1-10 A construction method for crack-resistant walls is provided: S1: After welding the frame assembly 1 in the factory, install the compensation assembly 4 with bolts, and then plan the installation position of the gap assembly 3 according to the size of the bricks 34 to be laid. Then lay a film or board at the bottom of the frame assembly 1 to separate the ground and cement mortar. After all are installed, lay bricks 34 in the area enclosed by the frame plate 12 and the groove plate 17 of the frame assembly 1. S2: After the bricks 34 are laid, pour cement mortar into the gaps between the bricks 34 and use a vibrator to remove air bubbles to ensure that the gaps between the bricks 34 are completely filled with cement mortar. S3: After the cement mortar has hardened, the formed panels are transported to the construction site and connected using the connecting components 2 as needed. Cement mortar is then poured between the installed frame components 1 to form a whole and increase the overall strength.
