Description

Technical Field

[0001] The utility model relates to the technical field of building pile foundation engineering, in particular to a pile foundation module structure. Background Art

[0002] Pile foundation consists of piles and pile caps (referred to as caps) connected to the top of the piles. It is divided into multi-pile deep foundations or single pile foundations. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations. Pile foundations are widely used in high-rise buildings.

[0003] The existing connection method between piles and caps includes bolt and nut connection, and for multi-pile deep foundations or single pile foundations, it is necessary to pre-embed bolts that are compatible with the multi-pile or single pile connection structure in the cap, and the pre-embedding operation needs to be performed when the cap is cast, which results in the existing cap being only compatible with multi-pile or single pile, and two types of caps need to be produced according to demand, which results in poor versatility and adaptability of the existing structure and high cost.

[0010] By adopting the above technical solution, a single connection column is installed during the casting of the pedestal to achieve the fixation of the single connection column and the pedestal, and then the single connection nut is used to achieve the fastening connection between the pedestal and the single pile column.

[0011] It is further configured as follows: the multi-connection structure includes a plurality of multi-connection bolts and a plurality of multi-connection nuts threadedly connected to the multi-connection bolts, and each of the multi-connection bolts passes through the connecting plate body and the multi-jointing pieces and is threadedly connected to the multi-connection nut.

[0012] By adopting the above technical solution, the connecting column passes through the connecting plate body and cooperates with the single connecting nut to realize the fixation of the base and the connecting plate body, and then cooperates with the set multiple connecting bolts and multiple connecting nuts to realize the fastening connection between the base and the multi-pile column.

[0013] It is further configured as follows: the connecting plate body is against the bottom of the support platform, and when the multiple connecting bolts pass through the connecting plate body, the bottom of the support platform is provided with a placement groove for placing the multiple connecting bolt heads at a position corresponding to the head of each multiple connecting bolt.

[0014] By adopting the above technical solution, this arrangement can achieve close contact between the base and the connecting plate, increase the contact surface to make it have higher strength, and thus improve the bearing load of the structure.

[0015] It is further configured that: the shape of the placement groove is adapted to the shape of the head of the multiple connection bolts and limits the circumferential rotation of the multiple connection bolts.

[0016] By adopting the above technical solution, the multiple connection bolts are set to be prohibited from rotating during the connection process through this setting structure, so as to achieve a convenient connection between the multiple connection bolts and the multiple connection nuts.

[0017] It is further configured as follows: a side support ring is sleeved on the side of the support platform, an outer expansion support ring is sleeved on the outer ring of the side support ring, and multiple groups of support components are connected between the outer expansion support ring and the side support ring.

[0018] By adopting the above technical solution, the foundation pit is dug, an outward support ring is set around the foundation pit and a side support ring is installed on the pedestal, and then the lateral support of both the foundation pit and the pedestal is achieved through the set support components, and the lateral support surface is increased to enhance the lateral assistance of the pile foundation, so that it has stronger lateral supporting force.

[0019] It is further configured as follows: the support assembly includes a first screw rod hinged to an external expansion support ring, a second screw rod hinged to a side support ring, and a double screw sleeve connecting the first screw rod and the second screw rod, and a reinforcement layer is provided on the outer periphery of the external expansion support ring.

[0020] By adopting the above technical solution, the double screw sleeve is rotated to drive the first screw and the second screw to move toward or away from each other, so as to achieve the tight contact between the outer support ring and the side support ring to achieve the support purpose; and the hinged structure is set to avoid the later settlement and affect the lateral support of the pile foundation; and the foundation pit and the side support ring are reinforced by the reinforcement layer to have better supporting force.

[0021] In summary, the utility model has the following beneficial effects: the utility model can make the cap adapt to multi-pile deep foundation or single pile foundation, thereby improving the versatility and poor adaptability of the pile foundation and reducing costs.
