After the first support plate is fixed to the wall top, the building foundation, the wall and the wall top are formed into a geometric whole, which can prevent the building from being deformed or the wall from being tilted or the joint seam from being uneven during the subsequent construction process or the hoisting of the wall top. The device has the characteristics of simple operation and good reinforcement effect.

Description

Technical Field

[0002] Buildings assembled on site from prefabricated wall panels are called prefabricated buildings. According to the form of prefabricated components and the construction method, they are divided into five types: block buildings, plate buildings, box buildings, skeleton plate buildings and rising plate and rising floor buildings. Prefabricated buildings began to arouse people's interest in the early twentieth century and were finally realized in the 1960s. Due to the fast construction speed and low production cost of prefabricated buildings, they were quickly promoted around the world. When prefabricated buildings are constructed on site, assembly components for connecting prefabricated building wall panels are indispensable.

[0003] Patent No. CN114658254B ​​discloses a building wall reinforcement support device and its use method, including a lifting assembly, a length-adjustable reinforcement rod, and a connecting piece, wherein the connecting piece is used to connect the length-adjustable ends of two length-adjustable reinforcement rods, so that four length-adjustable reinforcement rods form a frame-like structure; the length-adjustable reinforcement rod includes a bearing plate, the inner cavity of the bearing plate is slidably provided with two sliding plates, and the side of the bearing plate away from its port is rotatably provided with a driving screw; the side of the bearing plate away from its port is provided with a fixed plate, and the surface of the fixed plate is rotatably provided with a driving shaft, and the upper end of the driving shaft is provided with a transmission assembly for driving the driving screw to rotate; the lifting end of the lifting assembly is provided with a plug-in assembly, and the plug-in assembly is plugged and matched with the fixed plate in the vertical direction. The beneficial effect is that it can realize the joint reinforcement support of four walls at the same time, so that the reinforcement support of the four walls constitutes a whole, which greatly improves the stability of the wall.

[0004] Although the above technical scheme can improve the stability of the wall, it is only applicable to old houses that have been built. During the assembly process of the prefabricated building wall, the above reinforcement support device still has the following defects: after the wall and the reinforcement support device are installed on the building foundation, on the one hand, the pressure of the wall top hoisted to the top of the wall cannot be used to automatically control the reinforcement support device to provide lateral support to the wall, and manual adjustment is required to complete the support function.

[0057] A method for reinforcing a prefabricated building wall, comprising:

[0058] S100, first fix the built-in steel structure reinforcement 1 to the building foundation and then fix the wall 2 to the building foundation, or first fix the wall 2 to the building foundation and then fix the built-in steel structure reinforcement 1 to the building foundation, when the steel structure main body 11 is a steel bar structure, grouting (filling concrete) is performed in the gap between the built-in steel structure reinforcement 1 and the wall 2;

[0059] S200, pre-install the first lateral support mechanism 5, the second lateral support mechanism 6 and the longitudinal support mechanism 7 with the external support reinforcement member 4. When installing the first lateral support mechanism 5, it is necessary to fix the fixing shell 51 and the first bolt 511 with the first threaded hole 45 at the highest point on the surface of the external support reinforcement member 4 to ensure that the second end threaded pin 523 is located at the bottom of the inclined guide rail 732. At this time, the height of the second support plate 71 is higher than the height of the wall 2. When installing the first lateral support mechanism 5, the fixing shell 51 and the first bolt 511 can be fixedly connected with the external support reinforcement member 4. The longitudinal support mechanism 7 is fixedly connected to any other first threaded hole 45 on the surface of the support reinforcement member 4. When installing the longitudinal support mechanism 7, first insert the longitudinal rod 72 into the third assembly hole 46, and then use the fourth bolt in the third threaded hole 712 to fix the longitudinal rod 72 to the second support plate 71, then insert the first end threaded pin 512 and the second end threaded pin 523 into the longitudinal guide rail 731 and the inclined guide rail 732 respectively, and finally, the first nut 513 and the second nut 524 are threadedly connected to the ends of the first end threaded pin 512 and the second end threaded pin 523 respectively;

[0060] S300, after the concrete solidifies, the assembled external support reinforcement member 4 is hoisted by hoisting equipment, and the longitudinal steel rod 12 in the internal steel structure reinforcement member 1 is inserted into the second assembly hole 43 on the surface of the steel plate 42 in the wall, and the external support reinforcement member 4 is lowered to the surface of the building foundation by hoisting equipment, and the base 44 is fixed to the building foundation by anchor bolts;

[0061] S400, after adjusting the height of the second lateral support mechanism 6 according to the height of the wall 2 or whether there are obstacles on the surface of the wall 2, insert the double-threaded rod 8 into the fourth assembly holes 526 on the surfaces of the upper and lower sets of wall cross arms 521, and use nuts 81 to threadably connect the two ends of the double-threaded rod 8;

[0062] S500, use the lifting equipment to lift the wall top 3 to the top of the wall 2, then adjust the angle and slowly lower it, so as to insert the longitudinal steel rod 12 into the first assembly hole 31 on the surface of the wall top 3. During this process, the pressure of the wall top 3 is transmitted to the lifting plate 73 through the second support plate 71 and the longitudinal rod 72, and the lifting plate 73 is driven to descend along the surface of the fixed shell 51. The descending lifting plate 73 transmits the lateral pressure to the wall head cross arm 521 through the sliding connection between the inclined guide rail 732 and the second end threaded pin 523, and drives the upper and lower sets of wall head cross arms 521 and the first support plate 522 to move laterally along the fixed shell 51 and support the walls 2 on both sides. The second support plate 71 is fixed to the wall top 3 by the third bolt, so as to achieve the purpose of supporting and reinforcing the wall 2.

[0063] S600. When all building walls 2 and wall tops 3 are installed, or when the reinforcement device needs to be removed, first remove the third bolt between the second support plate 71 and the wall top 3, and then remove the second bolt 47 between the inner wall steel plate 42 and the longitudinal steel frame 41. Since the inner wall steel plate 42 is completely hidden and pressed into the embedded groove 21, it will not affect the aesthetics of the building. Then remove the first bolt 511 on the fixing shell 51. At this time, the reinforcement device can be moved out from between the wall 2 and the wall top 3.

[0064] To sum up, on the one hand, the built-in steel structure reinforcement 1 can be used to fix the wall 2 and the wall top 3 from the joint. On the other hand, after the external support reinforcement 4 is fixed to the built-in steel structure reinforcement 1 and the building foundation, the downward pressure on the second support plate 71 when hoisting the wall top 3 can be used to drive the upper and lower groups of first support plates 522 to automatically support the walls 2 on both sides laterally. There is no need to manually adjust the position of the first support plate 522. It has the characteristics of simple operation and easy use. After the first support plate 522 is fixed to the wall top 3, the reinforcement device forms the building foundation, the wall 2 and the wall top 3 into a geometric whole, which can prevent the building from deformation or the wall 2 from tilting or uneven splicing during the subsequent construction process or the hoisting of the wall top 3, and has the characteristics of good reinforcement effect.
