Description

Technical Field

[0001] This utility model patent relates to the technical field of steel pipe columns, and more specifically, to a limiting structure for the precise installation of steel pipe columns and pile foundations. Background Technology

[0002] When connecting steel pipe columns to pile foundations, a limiting structure is needed to restrict the position of the steel pipe columns. During the limiting process, the position of each anchor bolt is restricted by the limiting structure. After multiple anchor bolts are restricted, they are then connected to the steel pipe columns to achieve the connection and fixation between the steel pipe columns and the pile foundations.

[0003] The limiting structure includes a single-layer arrangement of limiting rings with multiple limiting holes. The limiting rings are arranged on the steel reinforcement frame of the pile foundation, and the anchor bolts pass through the limiting holes to limit the anchor bolts.

[0004] In the existing technology, since the limiting structure only has a single layer of limiting holes, it is difficult to guarantee the verticality of the anchor bolts after limiting them, resulting in poor limiting accuracy and making it difficult to limit large steel pipe columns. Utility Model Content

[0005] The purpose of this utility model is to provide a limiting structure for the precise installation of steel pipe columns and pile foundations, aiming to solve the problem of low limiting accuracy in the existing limiting structures used for the installation of steel pipe columns and pile foundations.

[0006] This utility model is implemented as follows: a limiting structure for precise installation of steel pipe columns and pile foundations includes a limiting seat arranged on the steel reinforcement frame of the pile foundation and limiting multiple anchor bolts. The lower part of the anchor bolts is inserted and fixed in the pile foundation to form a fixed section, and the upper part of the anchor bolts extends to the top of the pile foundation to form a connecting section connected to the steel pipe column.

[0007] The lower part of the limiting seat is provided with multiple lower holes for the connecting section to pass through, and the upper part of the limiting seat is provided with multiple upper holes for the connecting section to pass through. The multiple lower holes and multiple upper holes are arranged around the circumference of the limiting seat at intervals, and the multiple upper holes and multiple lower holes are arranged vertically aligned.

[0008] Furthermore, the limiting seat includes a lower ring arranged in a circumferential manner, and a plurality of lower holes are disposed in the lower ring and arranged at intervals along the circumference of the lower ring.

[0009] Furthermore, the limiting seat includes an upper ring arranged in a circumferential manner and located above the lower ring, with a longitudinal gap between the upper ring and the lower ring; a plurality of the upper holes are disposed in the upper ring and arranged circumferentially around the upper ring.

[0010] Furthermore, a support structure is provided in the longitudinal interval, the support structure being connected to the upper ring and the lower ring respectively, and the support structure fixing the upper ring and the lower ring relative to each other.

[0011] Furthermore, the support structure includes a plurality of longitudinal rods, which are arranged around the circumferential ring at longitudinal intervals; the top of the longitudinal rods is connected to the upper ring, and the bottom of the longitudinal rods is connected to the lower ring.

[0012] Furthermore, the upper ring surrounds and forms an upper empty area, and the lower ring surrounds and forms a lower empty area, with the upper and lower empty areas aligned and connected vertically.

[0013] Furthermore, a center positioning structure for locating the position of the steel pipe pile is provided at the center of the lower empty area.

[0014] Furthermore, the lower empty area is provided with two intersecting positioning rods, the ends of which are connected to the lower ring. The intersection of the two positioning rods forms the central positioning structure, which is connected to a plumb bob.

[0015] Furthermore, the diameters of the upper hole and the lower hole are both larger than the diameter of the anchor bolt.

[0016] Furthermore, the upper ring is provided with an adjusting arc plate that is curved in an arc shape. The inner side of the adjusting arc plate has an inwardly facing side that is arranged longitudinally and abuts against the outer periphery of the anchor bolt, and the outer side of the adjusting arc plate has an outwardly facing side that is arranged obliquely and abuts against the inner sidewall of the upper hole.

[0017] Compared with existing technologies ， The limiting structure provided by this utility model for the precise installation of steel pipe columns and pile foundations utilizes upper and lower holes to form upper and lower positioning layers, ensuring the verticality of the anchor bolts and providing high limiting accuracy. After limiting the anchor bolts, the pile foundation is formed, and the anchor bolts and pile foundation are integrated as one. When installing steel pipe columns, the anchor bolts are directly used to connect to the steel pipe columns, so that the steel pipe columns and pile foundations are integrated as one.

[0025] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0026] The limiting structure for precise installation of steel pipe columns and pile foundations includes a limiting seat arranged on the steel reinforcement frame of the pile foundation and limiting multiple anchor bolts. The lower part of the anchor bolt is inserted and fixed in the pile foundation to form a fixed section, and the upper part of the anchor bolt extends to the top of the pile foundation to form a connecting section connected to the steel pipe column.

[0027] In actual construction, after the formwork is set up, a steel reinforcement frame is placed within the area enclosed by the formwork, and then concrete is poured to finally form the pile foundation.

[0028] The lower part of the limiting seat is provided with multiple lower holes 301 for the connecting section to pass through, and the upper part of the limiting seat is provided with multiple upper holes 101 for the connecting section to pass through. The multiple lower holes 301 and multiple upper holes 101 are arranged around the circumference of the limiting seat at intervals, and the multiple upper holes 101 and multiple lower holes 301 are arranged vertically aligned.

[0029] The aforementioned limiting structure for precise installation of steel pipe columns and pile foundations utilizes the upper hole 101 and the lower hole 301 to form upper and lower positioning layers, ensuring the verticality of the anchor bolts and providing high limiting accuracy. After limiting the anchor bolts, the pile foundation is formed, and the anchor bolts and pile foundation are integrated as one unit. When installing the steel pipe columns, the anchor bolts are directly used to connect to the steel pipe columns, so that the steel pipe columns and pile foundations are integrated as one unit.

[0030] In this embodiment, the steel pipe column includes a column body 400. A connecting ring 401 extends outward from the outer periphery of the bottom of the column body 400. The connecting ring 401 is arranged around the circumference of the column body 400. The connecting ring 401 is provided with a plurality of column holes 402, which are arranged at intervals along the circumference of the connecting ring 401.

[0031] Once the anchor bolts pass through the upper hole 101 and are positioned, they are fixed to the pile foundation after the pile foundation is formed. When the steel pipe column is assembled with the pile foundation, multiple anchor bolts are passed through multiple column holes 402 to realize the installation of the steel pipe column and the pile foundation.

[0032] In this embodiment, the limiting seat includes a lower ring 300 arranged in a circumferential manner, and a plurality of lower holes 301 are disposed in the lower ring 300 and arranged at intervals along the circumference of the lower ring 300. By arranging the lower ring 300, the arrangement of the plurality of lower holes 301 is facilitated.

[0033] In this embodiment, the limiting seat includes an upper ring 100 arranged in a circumferential manner and located above the lower ring 300, with a longitudinal gap 200 between the upper ring 100 and the lower ring 300; a plurality of upper holes 101 are disposed in the upper ring 100 and arranged circumferentially around the upper ring 100.

[0034] By arranging the upper ring 100, it is convenient to arrange multiple upper holes 101, and the upper ring 100 and the lower ring 300 are arranged vertically at intervals, which saves materials and facilitates the manufacturing of the limit seat.

[0035] In this embodiment, a support structure is provided in the longitudinal interval 200. The support structure is connected to the upper ring 100 and the lower ring 300 respectively, and the support structure fixes the upper ring 100 and the lower ring 300 relative to each other.

[0036] In this embodiment, the support structure includes a plurality of longitudinal rods 201, which are arranged around the longitudinal spacing 200 in a circumferential manner; the top of the longitudinal rods 201 is connected to the upper ring 100, and the bottom of the longitudinal rods 201 is connected to the lower ring 300.

[0037] Multiple longitudinal rods 201 provide vertical support between the upper ring 100 and the lower ring 300, ensuring the overall structural stability of the limit seat.

[0038] In this embodiment, the upper ring 100 surrounds and forms the upper empty area, and the lower ring 300 surrounds and forms the lower empty area. The upper and lower empty areas are aligned and connected vertically. This greatly saves materials, reduces the weight of the limiting seat, and facilitates the transfer and movement of the limiting seat.

[0039] In this embodiment, a central positioning structure for locating the position of the steel pipe pile is provided at the center of the lower empty area. During construction, after the limiting seat is placed on the steel reinforcement frame, the limiting seat is moved until the central positioning structure is aligned with the center of the steel pipe column, thus determining the position of the limiting seat. Then, the limiting operation of multiple anchor bolts is performed.

[0040] In this embodiment, two intersecting positioning rods are provided in the lower empty area. The ends of the positioning rods are connected to the lower ring 300. The intersection of the two positioning rods forms the central positioning structure, and the central positioning structure is connected to a plumb bob.

[0041] By arranging a plumb bob, it is easy to align the center positioning structure with the center of the steel pipe column. Secondly, the lower cavity is circular in shape, and two positioning rods extend along the diameter of the lower cavity. The intersection of the two positioning rods is the center of the lower cavity, which is the center positioning structure.

[0042] In this embodiment, the width of the lower ring 300 is greater than the width of the upper ring 100, which makes it easier for the lower ring 300 to be placed stably on the steel reinforcement frame, and the bottom of the lower ring 300 is flat.

[0043] In this embodiment, the diameter of the upper hole 101 and the diameter of the lower hole 301 are larger than the diameter of the anchor bolt. After the anchor bolt passes through the lower hole 301 and the upper hole 101, the anchor bolt can be finely adjusted within a set range to improve the positioning accuracy of the anchor bolt and facilitate the connection between the anchor bolt and the steel pipe column.

[0044] In this embodiment, the upper ring 100 is provided with an adjusting arc plate 500. The adjusting ring plate is arranged in an arc shape. The inner side of the adjusting arc plate 500 has a longitudinally arranged inner side surface 501, and the outer side of the adjusting arc plate 500 has an inclined arranged outer side surface 502.

[0045] After the anchor bolt passes through the upper hole 101, when it is necessary to make a fine adjustment to the position of the anchor bolt, the adjusting arc plate 500 is sleeved on the outer circumference of the anchor bolt and inserted into the upper hole 101. The inner side 501 abuts against and wraps around the outer circumference of the anchor bolt, and the outer side 502 abuts against the inner side wall of the upper hole 101. By moving the adjusting arc plate 500 up and down, the anchor bolt can be adjusted by swinging.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
