Description

Technical Field

[0001] The utility model provides a fixed base for prefabricated buildings, belonging to the technical field of prefabricated buildings. Background Technique

[0002] A prefabricated building refers to a building in which a large number of on-site operation works in the traditional construction method are transferred to the factory. Building components and fittings are processed and manufactured in the factory and transported to the building construction site, and are assembled and installed on-site through reliable connection methods. The fixed base of a prefabricated building is also called a precast cement pier, which is used to support the building feet. The common fixed base is a convex cement platform, and several embedded screw rods are embedded inside it. The building feet are located above the convex cement platform, and the embedded screw rods pass through the building feet and are connected with nuts, so as to achieve the functions of fixing and supporting.

[0003] The existing fixed bases for prefabricated buildings can basically meet the use requirements. However, once the position of the fixed base is deviated, it is possible that the embedded screw rods cannot pass through the anchor feet of the columns of the prefabricated building, which may lead to the inability to install and fix the columns of the prefabricated building. And only by connecting the embedded screw rods through the building feet and then with nuts to achieve the functions of fixing and supporting. Once the nuts rust, corrode or even fall off, it is possible that the columns of the prefabricated building fall off and collapse from the base, and the safety performance needs to be improved. The utility model provides a fixed base for prefabricated buildings. Summary of the Utility Model

[0004] The technical problem solved by the utility model is that once the position of the fixed base is deviated and the position of the embedded screw rods is deviated, it may lead to the inability to install and fix the columns of the prefabricated building; only by connecting the embedded screw rods through the building feet and then with nuts, it is possible that the columns of the prefabricated building fall off and collapse from the base, and the safety performance needs to be improved.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a fixed base for prefabricated buildings, including a base, a groove is provided at the top of the base, a plurality of first embedded screw rods are symmetrically provided on the bottom wall of the groove, a steel plate fixedly arranged on the first embedded screw rods is provided in the groove, second embedded screw rods are symmetrically provided on the side walls around the groove and are arranged between the first embedded screw rods, a hollow support rod is inserted at the end of the second embedded screw rod, a locking plate is provided between the ends of the hollow support rods, and a locking nut for limiting and locking the position of the hollow support rod is threadedly connected to the second embedded screw rod.

[0006] Further, the base is made of concrete material, and the groove is filled with concrete.

[0007] Further, a through hole through which a first embedded screw rod passes is provided on the steel plate, and an upper nut placed above the steel plate and a lower nut placed below the steel plate are threadedly connected to the first embedded screw rod.

[0008] Further, gaskets are provided between the upper nut, the lower nut and the steel plate.

[0009] Further, a prefabricated building column is provided at the top of the steel plate between the locking plates, and a flange is provided at the bottom of the prefabricated building column between the top of the steel plate and the bottom of the locking plate.

[0010] Further, the flange is fixedly arranged on the top of the steel plate by using one of spot welding, intermittent welding and full welding.

[0011] Advantages of the utility model:

[0012] 1. The prefabricated building column is lifted and moved by a crane, so that the flange supports on the top of the steel plate. By using tools to twist and adjust the position of the locking nut on the second embedded screw rod until the locking plate abuts against the side wall of the prefabricated building column, the flange can be translated and corrected in position on the top of the steel plate, which can effectively prevent the situation that the prefabricated building column cannot be installed and fixed due to the deviation of the position of the embedded screw rod.

[0013] 2. Operate the locking plates in all directions in the same way, and then the prefabricated building column can be clamped and fixed between the locking plates. After that, the flange is fixed on the top of the steel plate by intermittent welding, and then the prefabricated building column can be further fixed. Then, the concrete is poured into the groove, which can make the prefabricated building column firmly and stably fixed in the groove, effectively avoiding the situation that the prefabricated building column loosens or even falls off and topples from the base, and greatly improving the safety performance.

[0019] The present utility model will be further described below with reference to the drawings.

[0020] According to the attached Figure 1 , 2 , as shown in FIGS. 4: The present utility model provides a fixed base for a prefabricated building: including a base 1, the base 1 is made of concrete, a groove 2 is provided at the top of the base 1, a plurality of first embedded screws 3 are symmetrically provided on the bottom wall of the groove 2, a steel plate 4 fixedly arranged on the first embedded screws 3 is provided in the groove 2, a through hole through which the first embedded screw 3 passes is provided on the steel plate 4, an upper nut 9 placed above the steel plate 4 and a lower nut 10 placed below the steel plate 4 are threadedly connected to the first embedded screw 3, gaskets 11 are provided between the upper nut 9, the lower nut 10 and the steel plate 4, which serves to fix the steel plate 4 between the upper nut 9 and the lower nut 10, a column 12 of a prefabricated building placed between the locking plates 7 is provided at the top of the steel plate 4, and a flange 13 placed between the top of the steel plate 4 and the bottom of the locking plate 7 is provided at the bottom of the column 12 of the prefabricated building. The column 12 of the prefabricated building is lifted by a crane and moved onto the groove 2, and then the crane lowers the lifted column 12 of the prefabricated building so that the flange 13 supports on the top of the steel plate 4.

[0021] According to the attached Figure 1 , 3 , as shown in FIGS.: Second embedded screws 5 are symmetrically provided on the peripheral side walls of the groove 2 between the first embedded screws 3, hollow support rods 6 are inserted at the ends of the second embedded screws 5, a locking plate 7 is provided between the ends of the hollow support rods 6, and a locking nut 8 for limiting and locking the position of the hollow support rod 6 is threadedly connected to the second embedded screw 5. By using a tool to rotate the locking nut 8 to adjust its position on the second embedded screw 5, the locking nut 8 is moved towards the column 12 of the prefabricated building, so that the hollow support rod 6 and the locking plate 7 are moved towards the column 12 of the prefabricated building until the locking plate 7 abuts against the side wall of the column 12 of the prefabricated building, enabling the flange 13 to translate and correct the position on the top of the steel plate 4.
