Description

Technical Field

[0001] This utility model relates to the field of building support structure technology, and in particular to a cross-type central support earthquake-resistant building structure. Background Technology

[0002] Building structure refers to the spatial load-bearing system within a building, constructed from building materials to withstand various loads and actions, acting as a framework. Building structures can be categorized based on the building materials used, including concrete structures, masonry structures, steel structures, light steel structures, timber structures, and composite structures. Earthquake-resistant buildings are those that must be designed to withstand earthquakes in areas with a seismic fortification intensity of 6 degrees or higher.

[0003] Currently, the building structures used for construction typically involve inserting columns deep into the ground and adding concrete during foundation construction to enhance stability. However, because the columns are inserted into the ground, the contact support formed between them and the ground is not ideal, resulting in insufficient earthquake resistance. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cross-type centrally supported earthquake-resistant building structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cross-type centrally supported seismic-resistant building structure includes a support column, an installation hole is provided in the middle of the outer wall of the support column, and sliding grooves communicating with the installation hole are provided at equal intervals on the outer wall of the support column. An unfolding mechanism is installed in the sliding groove, and an adjusting component for unfolding the unfolding mechanism is installed in the installation hole.

[0007] The unfolding mechanism includes a pressure plate rotatably mounted at the bottom of the inner wall of the chute. A connecting plate is rotatably mounted on the inner wall of the pressure plate, and a pressure rod is fixed to the bottom of the connecting plate. A slot is opened on the pressure plate, and the pressure rod passes through the slot. The adjusting component includes a lead screw rotatably mounted in a mounting hole. A lead screw nut that matches the lead screw is installed on the lead screw. A connecting block is fixed to the outer wall of the lead screw nut at a position corresponding to the chute. The connecting block is rotatably connected to the connecting plate. When a tool that matches the regular hexagonal slot is removed, the lead screw rotates. The rotating lead screw causes the lead screw nut to move downward, thereby deflecting the connecting plate and pushing the pressure plate to unfold. The pressure plate and pressure rod form a cross-shaped structure for effective expansion. Then, cement is poured to ensure the stability of the support column. The unfolded pressure plate and pressure rod increase contact with the concrete, improving stability.

[0008] With the above structure: a first baffle is fixed to the bottom of the outer wall of the pressure rod, and a second baffle corresponding to the first baffle is fixed to the top of the outer wall of the pressure plate. The second baffle is provided with a fitting groove that matches the first baffle. The arrangement of the first baffle and the second baffle further increases the contact area, strengthens the stability, and when retracted, the first baffle can move closer to the fitting groove.

[0009] Preferably, the top of the lead screw has a regular hexagonal slot.

[0010] Preferably, the top and bottom of the support column are provided with a plurality of second screw holes, the bottom and top of the support column are respectively equipped with a lower mounting plate and an upper mounting plate, and the lower mounting plate and the upper mounting plate are provided with a first screw hole corresponding to the second screw hole. The first screw hole and the second screw hole are connected by bolts, and the upper mounting plate is provided with a through hole corresponding to the lead screw.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The system is equipped with a support column, a groove and mounting holes on the outer wall of the support column, and an unfolding mechanism and adjusting components. The unfolding mechanism includes a connecting plate, a pressure plate, and a pressure rod fixed to the bottom of the connecting plate. The pressure rod, connecting plate, and pressure plate form a cross structure. During construction, the support column is placed in a pre-dug hole. Then, a tool that fits the regular hexagonal groove is taken out, causing the lead screw to rotate. The rotating lead screw causes the lead screw nut to move down, thereby deflecting the connecting plate and pushing the pressure plate to unfold. The pressure plate and pressure rod form a cross-like structure, effectively expanding the support column. Cement is then poured to ensure the stability of the support column. The unfolded pressure plate and pressure rod increase contact with the concrete, improving stability. Before use, the pressure plate and pressure rod can be retracted.

[0013] 2. It is equipped with a first baffle and a second baffle to further increase the contact area and enhance stability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A cross-type centrally supported earthquake-resistant building structure includes a support column 1, an installation hole 10 is provided in the middle of the outer wall of the support column 1, and sliding grooves 9 are provided at equal intervals on the outer wall of the support column 1, communicating with the installation hole 10. An unfolding mechanism 8 is installed in the sliding groove 9, and an adjusting component for unfolding the unfolding mechanism 8 is installed in the installation hole 10.

[0021] The unfolding mechanism 8 includes a pressure plate 16 rotatably mounted at the bottom of the inner wall of the slide 9. A connecting plate 15 is rotatably mounted on the inner wall of the pressure plate 16. A pressure rod 18 is fixed at the bottom of the connecting plate 15. A slot 17 is opened on the pressure plate 16, and the pressure rod 18 passes through the slot 17. The adjusting component includes a lead screw 11 rotatably mounted in the mounting hole 10. A lead screw nut 13 is installed on the lead screw 11 and is adapted to it. A connecting block 14 is fixed on the outer wall of the lead screw nut 13 at the position corresponding to the slide 9. The connecting block 14 is rotatably connected to the connecting plate 15. When a tool adapted to the regular hexagonal slot 12 is taken out, the lead screw 11 is rotated. The rotating lead screw 11 causes the lead screw nut 13 to move down, thereby deflecting the connecting plate 15 and pushing the pressure plate 16 to unfold. The pressure plate 16 and the pressure rod 18 form a cross-shaped structure for effective expansion. Then, cement is poured to ensure the stability of the support column 1. The unfolded pressure plate 16 and the pressure rod 18 increase the contact with the concrete and improve stability.

[0022] With the above structure: a first baffle 19 is fixed to the bottom of the outer wall of the pressure rod 18, and a second baffle 20 corresponding to the first baffle 19 is fixed to the top of the outer wall of the pressure plate 16. The second baffle 20 is provided with a fitting groove 21 that is adapted to the first baffle 19. The arrangement of the first baffle 19 and the second baffle 20 further increases the contact area, strengthens the stability, and when retracted, the first baffle 19 can move closer to the fitting groove 21.

[0023] With the above structure, a regular hexagonal slot 12 is provided at the top of the lead screw 11.

[0024] With the above structure: the top and bottom of the support column 1 are provided with a number of second screw holes 5, the bottom and top of the support column 1 are respectively equipped with a lower mounting plate 2 and an upper mounting plate 3, and the lower mounting plate 2 and the upper mounting plate 3 are provided with a first screw hole 4 corresponding to the second screw hole 5. The first screw hole 4 and the second screw hole 5 are connected by bolts 6, and the upper mounting plate 3 is provided with a through hole 7 corresponding to the lead screw 11.

[0025] Working principle: The system consists of a support column 1 with a groove 9 and mounting holes 10 on its outer wall, and an unfolding mechanism 8 and adjusting components. The unfolding mechanism 8 includes a connecting plate 15, a pressure plate 16, and a pressure rod 18 fixed to the bottom of the connecting plate 15. The pressure rod 18, connecting plate 15, and pressure plate 16 form a cross structure. During construction, the support column 1 is placed in a pre-dug hole. A tool that fits the regular hexagonal slot 12 is then used to rotate the lead screw 11. The rotating lead screw 11 causes the lead screw nut 13 to move downward, which in turn causes the connecting rod 15 to deflect, pushing the pressure plate 16 to unfold. The pressure plate 16 and pressure rod 18 form a cross structure, effectively expanding the support column. Cement is then poured to ensure the stability of the support column 1. The unfolded pressure plate 16 and pressure rod 18 increase contact with the concrete, improving stability. Before use, the pressure plate 16 and pressure rod 18 can be retracted. A first baffle 19 and a second baffle 20 are provided to further increase the contact area and strengthen the stability.
