Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a settlement prevention structure for light buildings in backfill areas. Background Technique

[0002] Light buildings in a project (such as landscape pools, gazebos, sentry boxes, etc.) usually choose to use shallow foundations due to their light self-weight. However, when a light building is located above a backfill area, the shallow foundation is prone to damage or inclination due to the uneven settlement of the backfill soil, which affects the use of the light building.

[0003] To reduce the influence of the uneven settlement of the backfill soil on the building, the existing technology generally sets multiple steel pipe piles under the building, binds the raft foundation steel bars on the tops of the multiple steel pipe piles, and finally pours the raft foundation on the tops of the multiple steel pipe piles to adapt to the situation of small foundation bearing capacity or large backfill soil depth.

[0004] According to relevant specifications, during the construction of steel pipe piles, multiple anchoring steel bars need to be set on their tops. The end plate welding steel bar connection is a relatively common connection method. This method requires welding multiple connecting plates on the top of the steel pipe pile after the steel pipe pile is hammered to the predetermined position, and then welding multiple anchoring steel bars to the corresponding connecting plates respectively. However, the operation time of welding multiple connecting plates on the end plate is long and the steps are relatively cumbersome, resulting in a slow construction progress. Content of the Utility Model

[0005] The utility model aims to provide a settlement prevention structure for light buildings in backfill areas to solve the problem of relatively cumbersome steps and slow construction progress in the above scheme.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] A settlement prevention structure for light buildings in backfill areas includes steel pipe piles and a raft foundation. A plurality of the steel pipe piles are arranged at intervals and are respectively inserted into the foundation. An installation seat is fixedly arranged at the top of each steel pipe pile. A plurality of connecting plates are fixedly arranged at intervals along the circumference of the top of the installation seat. A steel reinforcement cage is arranged in the raft foundation, and the bottom reinforcement of the steel reinforcement cage is welded and connected to the top of the installation seat. Among them, the steel pipe pile and the installation seat are of a split forming structure.

[0008] The principle and effect of this technical scheme:

[0009] During construction, insert multiple steel pipe piles into the foundation respectively, and make the upper edges of the multiple steel pipe piles at the same height. Clean the surface of the foundation to make the steel pipe piles protrude from the surface of the foundation by a certain length. Fix the mounting seat on the top of the steel pipe pile, and weld the anchor bars on the side walls of each connecting plate on each mounting seat. Then, tie the steel reinforcement cage above the mounting seat, weld the bottom steel bars of the steel reinforcement cage to the top of the mounting seat, and finally pour concrete.

[0010] Through the above settings, by fixedly installing a mounting seat with multiple connecting plates on the top of the steel pipe pile, the mounting seat with connecting plates can be prefabricated and then installed on the top of the steel pipe pile on site, so that it is not necessary to weld the connecting plates one by one on the top of each steel pipe pile on site, which simplifies the operation steps and speeds up the construction progress.

[0011] In the present utility model, an outer edge is fixedly arranged at the top of the outer periphery of the mounting seat. Through the above settings, the connection between the steel pipe pile and the raft foundation can be strengthened.

[0012] In the present utility model, the top of the steel pipe pile has an end plate, and a plurality of nut grooves are arranged at intervals along the circumference of the bottom of the end plate.

Through holes matching the nut grooves are arranged on the side wall of the sleeve. The bottoms of the plurality of connecting plates are respectively fixedly connected to the top of the annular plate. The outer edge is fixedly arranged at the top of the outer periphery of the annular plate.

[0013] The principle and effect of this technical solution:

[0014] Put the sleeve on the top of the steel pipe pile, and rotate the sleeve to align the through holes on the sleeve with the nut grooves on the end plate. Pass the bolts through the through holes and thread them into the nut grooves until the nuts abut against the outer wall of the sleeve to fixedly install the mounting seat on the top of the steel pipe pile.

[0015] Through the above settings, it is convenient for the staff to fixedly install the mounting seat on the top of the steel pipe pile, ensuring the connection quality and improving the installation efficiency at the same time.

[0016] In the present utility model, a plurality of stiffening ribs are arranged at intervals along the circumference of the outer wall of the sleeve, and the top of the stiffening ribs is fixedly connected to the outer edge. Through the above settings, it can prevent the outer edge from bending due to stress and improve the stability of the device.

[0017] In the present utility model, the top of the steel pipe pile has an end plate, and an annular groove is arranged along the circumference of the bottom of the end plate. The mounting seat includes two symmetrically arranged arc-shaped hoops. The top of the hoop is fixedly provided with a semi-circular mounting plate. The bottom of the inner wall of the hoop is provided with a semi-circular convex strip. Connecting ears are respectively fixedly arranged at the left and right ends of the hoop, and through connection holes are arranged on the connecting ears. The bottoms of the plurality of connecting plates are respectively fixedly connected to the top of the mounting plate. The outer edge is fixedly arranged at the top of the outer periphery of the mounting plate.

[0018] Principle and effect of this technical solution:

[0019] Place two hoop fasteners on both sides of the steel pipe pile facing each other, make them close to the steel pipe pile, and snap the convex strips into the grooves. Rotate the two hoop fasteners to align the connection holes on the two hoop fasteners. Pass bolts through the connection holes on the two hoop fasteners, and sleeve nuts at one end of the bolts until the hoop fasteners tightly press the steel pipe pile.

[0020] With the above settings, it is convenient for the staff to fixedly install the mounting seat on the top of the steel pipe pile, ensuring the connection quality while improving the installation efficiency.

[0021] In the present utility model, a plurality of stiffening ribs are arranged at intervals along the circumferential direction of the outer wall of the hoop fastener, and the top of the stiffening rib is fixedly connected to the outer edge. With the above settings, it is possible to prevent the outer edge from bending due to stress and improve the stability of the device.

[0022] In the present utility model, a card slot with an arc-shaped cross-section is arranged vertically on the side wall of the connecting plate, and the card slot is used for clamping the anchoring steel bars. With the above settings, the staff can make the anchoring steel bars fit on the surface of the connecting plate, thereby facilitating the staff to weld the anchoring steel bars and the connecting plate.

[0023] In the present utility model, a plurality of the steel pipe piles are arranged in an array under the raft foundation. With the above settings, the device can evenly transfer the load and improve the stability of the present utility model. Description of the Drawings

[0033] First embodiment:

[0034] As shown in the Figures 1-4 accompanying drawings, the present utility model discloses a settlement prevention structure for a light building in a backfill area, including steel pipe piles 10 and a raft foundation 40. A plurality of steel pipe piles 10 are arranged at intervals and are respectively inserted into the foundation. At the top of each steel pipe pile 10, a mounting seat 20 is fixedly provided.
