Description

Technical Field

[0001] This invention relates to the field of steel structure building technology, and in particular to a prefabricated modular steel structure building. Background Technology

[0002] Prefabricated steel structure modular buildings are a high-end, green, and energy-saving type of prefabricated building. They offer advantages such as high integration, rapid construction, factory production, and the ability to be dismantled and reused. Currently, they are widely used in the tourism industry, apartment dormitories, commercial and public buildings, medical aid, and military fields. The thermal insulation and decorative composite system is a key factor affecting the practicality, comfort, and environmental performance of prefabricated steel structure modular buildings. Only by achieving close coordination and harmonious unity between the thermal insulation and decorative composite system and other structural systems can the advantages of prefabricated steel structure modular buildings be guaranteed.

[0003] A prefabricated steel structure modular building composite insulation and decoration structure disclosed in Chinese patent CN202122563452.9 solves the problem of high loss rate in the disassembly and assembly of prefabricated steel structure modular building insulation and decoration system, and improves construction efficiency and reduces construction costs.

[0004] The disadvantages of existing prefabricated steel structure modular buildings: The stability of the connection structure between existing prefabricated steel structure modular buildings and the ground is poor, which affects the stability of the modular building. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular prefabricated steel structure building.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated steel structure modular building includes a base plate, a slot is provided on the outer side of the top of the base plate, a structural frame is fixedly connected to the base plate through the slot, a support block is fixedly connected to the bottom of the structural frame, and sliding grooves are provided on both sides of the top of the base plate, a protective plate is slidably connected to the base plate through the sliding grooves.

[0008] Optionally, the support block has a triangular structure, the orientation of the support block is adapted to the bottom orientation of the structural frame, and the bottom of the support block is attached to the top of the base plate.

[0009] The above technical solution involves reinforcing the structural frame by setting up triangular support blocks to improve the stability of the building and using the support blocks instead of slab reinforcement to increase the bending resistance of the structural frame.

[0010] Optionally, an anchor groove is provided on one side of the support block and on the base plate. The positions of the anchor groove on the support block and the base plate are adapted to each other. The anchor groove is inclined to the outside of the base plate, and an anchor is fixedly connected in the anchor groove.

[0011] The above technical solution involves setting anchor grooves on the base plate and support blocks, allowing anchors to pass through the grooves to connect and fix the base plate and structural frame together. The base plate is then nailed to the ground by the anchors, improving the overall stability of the building. Setting the anchor grooves at an angle allows the anchors to be inserted into the soil at an angle, enabling the anchors to penetrate deeper into the soil when the building is subjected to force, thus improving the compressive strength of the building structure.

[0012] Optionally, the diameter of the anchor rod is adapted to the inner diameter of the anchor groove, and the length of the anchor rod is greater than the depth of the anchor groove.

[0013] Optionally, a plurality of contraction grooves are provided on the outer side of the bottom of the anchor rod, and each contraction groove is fixedly connected with a spring piece.

[0014] Optionally, the shape of the spring piece is adapted to the shape of the contraction groove, the spring piece is made of alloy spring steel, and the spring piece opens outward from the contraction groove.

[0015] The above technical solution involves installing spring plates on the anchor rod. After the anchor rod is inserted into the soil, when the anchor rod is subjected to outward tension, the spring plates open outward to increase the interlocking area with the soil layer, thereby providing more reaction force. When the anchor rod is inserted into the anchor groove and the soil layer, the spring plates retract into the shrinkage groove to avoid affecting the installation of the anchor rod.

[0016] Optionally, the grooves are all located inside the support block, and the bottom of the protective plate is provided with a slider that matches the shape of the groove.

[0017] Optionally, the cross-sectional shape of the chute is T-shaped, and the height of the protective plate is equal to the height of the structural frame.

[0018] Optionally, the outer side of the protective plate is bent outward, and the degree of bending of the protective plate is equal to the distance from the protective plate to the inner wall of the structural frame.

[0019] The above technical solution is adopted: the side walls of the building are reinforced by setting up a combination of protective plates and structural frames, and the anchor grooves and support blocks are wrapped to improve the overall integrity of the building.

[0020] Optionally, a triangular slot is provided at the bottom of the inner side of the protective plate, and the triangular slot of the protective plate is adapted to the shape of the inner part of the support block.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. This prefabricated steel modular building reinforces the structural frame with triangular support blocks, improving its stability. The support blocks replace steel reinforcement, increasing the frame's bending resistance. Anchor grooves on the base plate and support blocks allow anchors to pass through, connecting and fixing the base plate and frame together. The base plate is then nailed to the ground, further enhancing overall stability. The inclined anchor grooves allow the anchors to penetrate deeper into the soil, increasing compressive strength when the building is subjected to stress.

[0023] 2. This prefabricated steel structure modular building uses spring plates on the anchor rods. After the anchor rod is inserted into the soil, when the anchor rod is subjected to outward tension, the spring plates open outward to increase the interlocking area with the soil layer, thereby providing more reaction force. When the anchor rod is inserted into the anchor rod groove and the soil layer, the spring plates retract into the shrinkage groove to avoid affecting the installation of the anchor rod.

[0024] 3. This prefabricated steel structure modular building reinforces the building's side walls by combining protective panels with the structural frame, and encloses the anchor grooves and support blocks, thereby improving the building's overall integrity. Attached Figure Description

[0035] Example 1: The support block 4 is a triangular structure. The direction of the support block 4 is adapted to the bottom direction of the structural frame 3. The bottom of the support block 4 is in contact with the top of the base plate 1. By setting the triangular support block 4, the structural frame 3 is reinforced, thereby improving the stability of the structure. The support block 4 is used to replace the slab reinforcement to increase the bending resistance of the structural frame 3.

[0036] Example 2: Anchor grooves 7 are provided on one side of the support block 4 and on the base plate 1. The positions of the anchor grooves 7 on the support block 4 and the base plate 1 are matched. The anchor grooves 7 are inclined to the outside of the base plate 1. An anchor rods 8 are fixedly connected in the anchor grooves 7. By setting anchor grooves 7 on the base plate 1 and the support block 4, the anchor rods 8 can pass through the anchor grooves 7 to connect and fix the base plate 1 and the structural frame 3 together. The base plate 1 is nailed to the ground by the anchor rods 8, which improves the overall stability of the building. Setting the anchor grooves 7 to be inclined allows the anchor rods 8 to be inserted into the soil layer at an incline. When the building is subjected to force, the anchor rods 8 can be inserted into the soil layer more deeply, which improves the compressive strength of the building structure.

[0037] Example 3: The diameter of the anchor rod 8 is matched with the inner diameter of the anchor rod groove 7, and the length of the anchor rod 8 is greater than the depth of the anchor rod groove 7. Several contraction grooves 9 are opened on the outer side of the bottom of the anchor rod 8. Each contraction groove 9 is fixedly connected with a spring piece 10. The shape of the spring piece 10 is matched with the shape of the contraction groove 9. The material of the spring piece 10 is alloy spring steel. The spring piece 10 opens outward from the contraction groove 9. By setting the spring piece 10 on the anchor rod 8, after the anchor rod 8 is inserted into the soil layer, when the anchor rod 8 is subjected to an outward pulling force, the spring piece 10 opens outward to increase the interlocking area with the soil layer, thereby enabling it to provide more reaction force. When the anchor rod 8 is inserted into the anchor rod groove 7 and the soil layer, the spring piece 10 retracts into the contraction groove 9 to avoid affecting the installation of the anchor rod 8.

[0038] Example 4: The slide grooves 5 are all located inside the support blocks 4. The bottom of the protective plate 6 is provided with a slider that matches the shape of the slide groove 5. The cross-sectional shape of the slide groove 5 is T-shaped. The height of the protective plate 6 is equal to the height of the structural frame 3. The outer side of the protective plate 6 is bent outward. The degree of bending of the protective plate 6 is equal to the distance from the protective plate 6 to the inner wall of the structural frame 3. By setting the protective plate 6 and the structural frame 3 together, the side wall of the building is reinforced, and the anchor groove 7 and the support block 4 are wrapped up, thereby improving the overall integrity of the building.

[0039] Example 5: A triangular slot is provided at the bottom of the inner side of the protective plate 6, and the triangular slot of the protective plate 6 is adapted to the shape of the inner part of the support block 4.

[0040] The working principle of this invention is as follows:

[0041] S1. First, fix the base plate 1, then snap the structural frame 3 into the slot 2, and insert the anchor rod 8 into the anchor rod slot 7 and the soil layer to complete the fixation.

[0042] S2. Then slide the protective plate 6 into the groove 5 to wrap the inside of the support block 4.

[0043] Compared with the prior art, the present invention has the following advantages:

[0044] 1. This prefabricated steel modular building reinforces the structural frame 3 by setting triangular support blocks 4 to enhance its stability. The support blocks 4 replace the slab reinforcement to increase the bending resistance of the structural frame 3. Anchor grooves 7 are set on the base plate 1 and the support blocks 4, allowing anchors 8 to pass through the anchor grooves 7 to connect and fix the base plate 1 and the structural frame 3 together. The base plate 1 is nailed to the ground by the anchors 8, which improves the overall stability of the building. The anchor grooves 7 are set at an inclination so that the anchors 8 can be inserted into the soil at an inclination. When the building is subjected to force, the anchors 8 can be inserted into the soil layer more deeply, which improves the compressive strength of the building structure.

[0045] 2. In this prefabricated steel structure modular building, by setting spring plates 10 on the anchor rod 8, after the anchor rod 8 is inserted into the soil layer, when the anchor rod 8 is subjected to outward tension, the spring plates 10 open outward to increase the interlocking area with the soil layer, thereby enabling it to provide more reaction force. When the anchor rod 8 is inserted into the anchor groove 7 and the soil layer, the spring plates 10 retract into the shrinkage groove 9 to avoid affecting the installation of the anchor rod 8.

[0046] 3. This prefabricated steel structure modular building reinforces the building's side walls by combining protective plates 6 with the structural frame 3, and encloses the anchor grooves 7 and support blocks 4, thereby improving the building's overall integrity.
