Description

Technical Field

[0001] This utility model relates to the field of prefabricated PC building structure technology, specifically a prefabricated PC building structure. Background Technology

[0002] Prefabricated PC building structure is a new type of building structure system. It uses precast concrete components (PC components) as the main load-bearing components and constructs houses by prefabrication in the factory, transportation to the construction site and assembly. This structural system has advantages such as fast construction speed, easy quality control, energy saving and environmental protection, and reduction of on-site wet work and labor demand. It can effectively improve the level of building industrialization, realize the transformation and upgrading of the construction industry, and is widely used in residential, commercial and industrial buildings.

[0003] Existing precast concrete (PC) panels are mainly fixed by connecting components, and then a post-cast concrete area is set at the connection point of the PC panels. By pouring concrete on site, adjacent PC panels are connected into a whole. This connection method can give the structure good integrity and seismic performance. However, in actual operation, it is not only necessary to connect adjacent PC panels in a straight line, but also at right angles. Existing connecting components are difficult to adjust according to requirements, which affects the overall quality and performance of the structure. It may cause uneven stress at the connection point, reduce the integrity and seismic performance of the structure, and may also lead to excessively large or small gaps between PC panels, resulting in quality problems such as leakage. At the same time, it will also prolong the construction period and increase construction costs. Therefore, we propose a prefabricated PC building structure. Utility Model Content

[0028] 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.

[0029] Please see Figure 1-2 This utility model provides a technical solution: a prefabricated PC building structure, including two PC panels 1, with a plurality of steel bars 2 fixedly connected to the surface of the PC panels 1, and a connecting structure 3 provided on the surface of the PC panels 1. The connecting structure 3 includes a plurality of rectangular boxes 301, which are fixedly connected to both sides of the PC panels 1 by bolts 302. A connecting plate A303 and a connecting plate B304 are respectively inserted into the side of the two rectangular boxes 301 that are close to each other, and the connecting plates A303 and B304 are rotatably connected. Pins are slidably inserted into the surface of the rectangular boxes 301. 305. Several round holes 306 are opened on the surface of connecting plate A303 and connecting plate B304. The size of the pin 305 is adapted to the size of the round hole 306. By setting the connecting structure 3, the PC board 1 can be connected and fixed in both straight lines and right angles. Since it can flexibly realize straight lines and right angles, the PC board 1 can better adapt to the diverse architectural design needs, reduce the problem of uneven stress caused by unreasonable connection, reduce the probability of quality hazards such as cracks and leakage at the connection parts, and ultimately improve the safety, reliability and service life of the entire building structure.

[0030] Reference Figures 3-6As shown in this embodiment: a spring 314 is fitted onto the arc surface of the pin 305. The two ends of the spring 314 are fixedly connected to the pin 305 and the rectangular box 301, respectively. The pin 305 is inserted into the circular hole 306 by the force of the spring 314's contraction. The spring 314 improves the stability of the pin 305 within the circular hole 306, preventing it from slipping out due to shaking. Two rectangular slots 307 are provided on both sides of the PC board 1. The dimensions of the rectangular slots 307 are matched to the dimensions of the rectangular box 301. During installation, the rectangular box 301 can be inserted into the rectangular slots 307, preventing it from protruding from the surface of the PC board 1. This ensures a smooth and flat surface after splicing the PC board 1, improving the building's aesthetic quality. Two positioning grooves 308 are formed on the inner wall of the rectangular groove 307. Two positioning blocks 309 are fixedly connected to the surface of the rectangular box 301. The size of the positioning groove 308 matches the size of the positioning block 309. The positioning block 309 cooperates with the positioning groove 308 on the inner wall of the rectangular groove 307 to achieve precise positioning of the rectangular box 301, thereby facilitating the use of bolts 302 to fix the rectangular box 301 to the surface of the PC board 1. Two guide grooves 310 are formed on the surfaces of the connecting plate A303 and the connecting plate B304. Two fixing rods 311 are fixedly connected to the surface of the rectangular box 301. The fixing rods 311 slide against the inner wall of the guide groove 310. The fixing rods 311 slide within the guide groove 310, thereby preventing the connecting plate A303 and the connecting plate B304 from coming out of the rectangular box 301. Several supports 312 are fixedly connected to the surface of the rectangular box 301. The rectangular box 301 drives the supports 312 to insert between the reinforcing bars 2. During concrete pouring, this improves the firmness between the concrete and the rectangular box 301, further enhancing the stability of the connection to the PC board 1. Round rods 313 slide through the surfaces of the supports 312, penetrating the reinforcing bars 2. When the round rods 313 are inserted into the supports 312, they further restrict the position of the rectangular box 301, thus fixing it to the surface of the reinforcing bars 2, further improving the overall structure's integrity and seismic performance.

[0031] Working Principle: During the installation of PC board 1, the rectangular box 301 with positioning blocks 309 is first fixed in the rectangular grooves 307 on both sides of PC board 1 using bolts 302. The positioning blocks 309 cooperate with the positioning grooves 308 on the inner wall of the rectangular grooves 307 to achieve precise positioning of the rectangular box 301, thus facilitating the use of bolts 302 to fix the rectangular box 301 to the surface of PC board 1. For PC boards 1 requiring a straight connection, the connecting plate A 303 is inserted into one side of the rectangular box 301, and the connecting plate B 304 is inserted into the other side of the rectangular box 301. The positions of the connecting plates A 303 and B 304 are adjusted so that they are on the same straight line. At this time, the pins 305, under the action of the spring 314, are inserted into the corresponding round holes 306 on the surfaces of the connecting plates A 303 and B 304, completing the straight connection. Since the connecting plates A 303 and B 304 are rotatably connected, when a right-angle connection of PC boards 1 is required, the connecting plates A 303 and B 304 are rotated. Simultaneously, connecting plates A303 and B304 slide within the rectangular box 301. At this time, the fixing rod 311 slides within the guide groove 310, thus preventing connecting plates A303 and B304 from detaching from the rectangular box 301. When the included angle becomes 90 degrees, the pin 305 is released, and the pin 305 is inserted into the round hole 306 by the force of the spring 314 contraction. The pin 305 reaches the position of fixing connecting plates A303 and B304, thereby connecting and fixing the two PC plates 1 at right angles. When the rectangular box 301 is fixed to the surface of the PC plate 1, the rectangular box 301 will drive the bracket 312 to be inserted between the reinforcing bars 2. Then, the round rod 313 is inserted into the bracket 312. At this time, the round rod 313 further restricts the position of the rectangular box 301, thereby fixing it to the surface of the reinforcing bars 2. At this time, concrete is poured in the area of ​​the PC plate 1 connection, so that the adjacent PC plates 1 are connected into an integral structure, improving the integrity and seismic performance of the structure.
