Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated buildings, in particular to a prefabricated building steel structure. Background Technique

[0002] After retrieval, the application number 202320767584.X discloses a steel structure for prefabricated buildings that is easy to assemble, including a fixed frame. A cross plate is fixedly arranged at the top of the fixed frame. Two clamping plates are fixedly connected to the bottom of the cross plate. Two clamping grooves adapted to the clamping plates are opened at the top of the fixed frame. Threaded holes are opened on the outer surface walls of one sides of the two clamping plates. Fixed bolts are threadedly connected to the outer surface walls of both sides of the fixed frame, and one ends of the fixed bolts penetrate into the clamping grooves. A protection mechanism is fixedly arranged on the outer surface wall of one side of the fixed frame.

[0003] During the use of the steel structure for prefabricated buildings that is easy to assemble in this patent application, by rotating the movable plate on one side of the support column, the movable plate can drive the protective housing to move through the connecting plate during movement, and finally the protective housing can cover and protect the connection between the fixed bolt and the clamping plate and the clamping groove. However, during such use, the structure for moving and fixing the protective housing of this device is relatively cumbersome, making the use of this device inconvenient and also reducing the overall aesthetics of this device. Therefore, we propose a prefabricated building steel structure. Content of the Utility Model

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a prefabricated building steel structure.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme. A prefabricated building steel structure includes a fixed frame and a cross plate arranged on the top of the fixed frame. Connecting clamping grooves are opened at both ends of the top side of the fixed frame. Connecting clamping plates fixedly connected to the bottom wall surface of the cross plate are inserted into both connecting clamping grooves. The fixed frame is U-shaped. Movable sliding grooves are opened on the side wall surfaces at both ends of the top side of the fixed frame. Fixed threaded holes are penetrated and opened on the side wall surfaces of the two connecting clamping plates. Fixed bolts are threadedly connected to the mutually remote sides of the two movable sliding grooves. The end parts of the two fixed bolts extend into the two connecting clamping grooves and are threadedly connected to the internal threads of the two fixed threaded holes. Shrinkage grooves are opened on the bottom wall surfaces of the two movable sliding grooves. Protection mechanisms are arranged in both shrinkage grooves. The protection mechanism includes a protective sleeve body that is slidably connected to the inside of the shrinkage groove and can be adjusted in height.

[0006] Furthermore, two storage grooves corresponding to the positions of the two fixed bolts are opened on the side wall surfaces of the two movable sliding grooves, and the nut ends of the two fixed bolts are arranged inside the two storage grooves.

[0007] Furthermore, the upper part of the protective sleeve body is slidably connected to the side wall surface of the movable chute and corresponds to the position of the fixing bolt.

[0008] Furthermore, four support sliding holes are penetrated and opened at the four corner positions of the bottom wall surface of the protective sleeve body, and four support sliding rods in contact with the bottom inner wall surface of the contraction groove are slidably connected inside the four support sliding holes.

[0009] Furthermore, four support springs are fixedly installed between the bottom wall surfaces of the inner cavities of the four support sliding rods and the top inner wall surfaces of the four support sliding holes.

[0010] Furthermore, a pushing block is fixedly installed at the top of the side wall surface of the protective sleeve body.

[0011] Furthermore, a rubber pad is fixedly installed at the edge position of the top wall surface of the protective sleeve body.

[0012] Beneficial Effects

[0013] The utility model provides an assembled building steel structure. It has the following beneficial effects:

[0014] 1. For this assembled building steel structure, by setting the protection mechanism, during use, first, the two protective sleeve bodies are sleeved on the side wall surfaces of the two movable chutes to block the two storage grooves. The bottoms of the two protective sleeve bodies are slidably connected inside the two contraction grooves, and the bottom ends of the eight support sliding rods at the bottoms of the two protective sleeve bodies are in contact with the bottom inner wall surfaces of the two contraction grooves. The cross plate is inserted into the two connection card slots at the top of the fixed frame through the two connection card plates. Push the pushing block downward to drive the protective sleeve body to move downward, compress the support spring, force the support sliding rod to contract into the support sliding hole, and expose the storage groove. Thread the fixing bolts into the storage groove and the fixed threaded hole in sequence to complete the fixed installation between the fixed frame and the cross plate. At this time, the nut of the fixing bolt is received into the storage groove and will not block the upward movement of the protective sleeve body. Release the pushing block, and the protective sleeve body drives upward under the elastic force of the support spring to block the storage groove to form protection. The above operations are simple and practical, the structure is reasonable and compact, realizing the convenient protection operation of the fixing bolt of the device, and also improving the overall aesthetics of the device.

[0015] 2. For this assembled building steel structure, by setting the rubber pad, the tops of the two protective sleeve bodies are in fitting contact with the bottom wall surface of the cross plate through the two rubber pads. With the elastic force of the support spring, the rubber pad is placed more stably, thereby better protecting the fixing bolt and improving the structural stability of the device.
