Description
Technical Field
[0001] This utility model relates to the field of pile foundation construction, and in particular to a pile foundation support mold installation assembly. Background Technology
[0002] Pile foundation support formwork is a temporary support structure, manufactured according to the design requirements of the pile foundation, so that the concrete structure and components are shaped in the specified position and geometric dimensions, maintain their correct position, and bear the self-weight of the building formwork and the external loads acting on it. The purpose of formwork engineering is to ensure the quality of concrete engineering and construction safety, speed up the construction progress, and reduce project costs.
[0003] Patent No. ZL202322814497.8 discloses a novel formwork for the casting and support of building pile foundations. It features an auxiliary reinforcing mechanism on the outside of the main support plate to strengthen the support and prevent the main support plate from being pushed apart after grouting within the enclosed area, thus avoiding the main support plate overturning and ensuring the support effect of the formwork is not affected. However, this auxiliary reinforcing mechanism is mainly installed between the ground and the main support plate, providing lateral support to the main support plate in conjunction with the ground. When the main support plate is high, this auxiliary reinforcing mechanism is difficult to install. Furthermore, as the height of the main support plate increases, its lateral support force decreases, failing to achieve the desired lateral support effect. Therefore, it is necessary to research a pile foundation support mold installation assembly to solve the above problems. Summary of the Invention
[0004] The purpose of this utility model is to address the above-mentioned problems by providing a pile foundation support mold installation assembly that is simple in structure and easy to use.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A pile foundation support mold installation assembly includes template components. Several template components are arranged together to form a longitudinally arranged circular pipe structure, which is then grouted to form a pile foundation. The template components are arranged in pairs facing each other, and a traction mechanism is provided between the two opposing template components for connection. Corresponding clearance holes are provided on the two opposing template components, and these clearance holes are connected to both ends of the traction mechanism. The traction mechanism includes a traction rod and a locking component. The traction rod is positioned between the two opposing template components, with its length direction aligned with the diameter direction of the circular pipe structure. Both ends of the traction rod pass through the clearance holes on the two template components and are connected to the locking component located on the outside of the template component.
[0007] Furthermore, both ends of the pull rod along its length are provided with external threads, and the external threads at both ends along its length rotate in opposite directions; there are two locking components, which are located on the outside of two oppositely arranged template components, and the two locking components are respectively threaded to the external threads at both ends along the length of the pull rod.
[0008] Furthermore, the locking component includes a first arc component and a second arc component. The first arc component and the second arc component are symmetrically provided with semi-circular grooves on their opposite surfaces. The top and bottom ends of the first arc component are provided with first connecting ears, and the top and bottom ends of the second arc component are provided with second connecting ears. The second connecting ears are bolted to the first connecting ears, and the semi-circular grooves on the first arc component and the second arc component are combined to form a nut through groove. The inner wall of the nut through groove is provided with internal threads, and the internal threads are threaded to the external threads of the end of the pull rod.
[0009] Furthermore, two limiting plates are fixedly connected to the outer wall of the template component, with the two limiting plates located above and below the clearance hole, respectively; the locking component is disposed between the two limiting plates, and the locking component is provided with a limiting structure. Through the cooperation of the limiting structure and the limiting plates, the locking component is limited to prevent it from rotating around the pull rod.
[0010] Furthermore, a wrench is fixedly connected to one end of the pull rod so that the pull rod can be rotated using the wrench.
[0011] Furthermore, the circular pipe structure has several layers, and each layer of the circular pipe structure is formed by combining four template components; two sets of traction mechanisms are provided on the four template components, and the traction rods in the two sets of traction mechanisms are staggered vertically and perpendicular to each other in the length direction.
[0012] Furthermore, the template component is arranged in the shape of an arc plate, with a mounting protrusion at one end in the width direction and a mounting groove at the other end in the width direction; when several template components are combined, the mounting protrusions and mounting grooves at both ends of the width of the template component respectively engage with the mounting grooves and mounting protrusions on the adjacent template components on both sides.
[0013] Furthermore, the outer periphery of the top and bottom of the template component is integrally formed with mounting flanges, which are bolted to the template component in the upper or lower layer of the circular pipe structure; the mounting flange is provided with positioning bolt holes that penetrate the mounting flange longitudinally and are used for connection and installation.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are:
[0015] During installation, this utility model simply requires assembling adjacent template components to form a circular pipe structure. Then, the tie rod is passed through two opposing template components, and locking components are threaded onto both ends of the tie rod. Finally, the tie rod is rotated, causing the two locking components to press the two template components closer together until the template components are locked together with the adjacent template components. After the pile foundation has solidified, the locking components and template components can be removed, and the exposed ends of the tie rod can be cut off.
[0016] Under the action of the traction mechanism, this utility model creates a stable structure with mutual traction between two oppositely arranged template components, preventing the pouring of concrete from prying open the enclosed circular pipe structure or causing the template components to overturn. At the same time, this traction structure can maintain the lateral traction effect throughout the entire process of pile foundation pouring. It does not increase the installation difficulty as the template components increase in height, nor does it affect the lateral support force as the template components increase in height, effectively improving the formwork effect of pile foundation construction.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of the present utility model.
[0027] like Figures 1 to 8 As shown, this embodiment discloses a pile foundation support mold installation assembly, including a template 1. Several templates 1 are provided, and several templates 1 are combined to form a longitudinally arranged circular pipe structure, so that grout is injected into the inside to form a pile foundation.
[0028] The circular pipe structure is arranged in several layers from top to bottom, and each layer of the circular pipe structure is formed by assembling four template components 1; the four template components 1 are arranged in pairs facing each other, and a traction mechanism 2 is provided between the two opposing template components 1 and connected through the traction mechanism 2; the two opposing template components 1 are provided with corresponding clearance holes 101 and are connected to the two ends of the traction mechanism 2 through the clearance holes 101.
[0029] The pulling mechanism 2 includes a pulling rod 201 and a locking member 202. The pulling rod 201 is disposed between two opposing template parts 1, and the length direction of the pulling rod 201 is consistent with the diameter direction of the circular pipe structure. Both ends of the pulling rod 201 are provided with external threads 2011, and the external threads 2011 at both ends of the length direction are rotated in opposite directions. The two ends of the pulling rod 201 pass through the clearance holes 101 on the two template parts 1 respectively and are threadedly connected to the locking member 202 disposed on the outside of the template part 1. A wrench 2012 is fixedly connected to one end of the pulling rod 201 so that the pulling rod 201 can be rotated by the wrench 2012.
[0030] Two sets of traction mechanisms 2 are provided on the four template components 1. The traction rods 201 in the two sets of traction mechanisms 2 are staggered vertically and are perpendicular to each other in the length direction.
[0031] In the design, multiple sets of parallel traction mechanisms can be set between two opposing template components. When the traction rod in the traction mechanism rotates, the external threads at both ends rotate in opposite directions, causing the two locking components to move closer together and press the two template components closer together until the template components are tightly fitted with the adjacent template components. When grouting in the circular pipe structure, the traction rod is directly poured inside. After the pile foundation concrete has solidified, the locking components and template components are removed from the traction rod, and the end of the traction rod protruding outside the pile foundation is cut off. The metal traction rod poured into the pile foundation concrete can improve the strength of the pile foundation structure.
[0032] The locking component 202 is a split structure, which includes a first arc component 2021 and a second arc component 2022. The opposite surfaces of the first arc component 2021 and the second arc component 2022 are symmetrically provided with semi-circular grooves 2023. The top and bottom ends of the first arc component 2021 are provided with first connecting ears 2024, and the top and bottom ends of the second arc component 2022 are provided with second connecting ears 2025. The second connecting ears 2025 and the first connecting ears 2024 are bolted together, and the semi-circular grooves 2023 on the first arc component 2021 and the second arc component 2022 are combined to form a nut through groove. The inner wall of the nut through groove is provided with internal threads, which are threadedly connected to the external threads of the end of the pull rod 201 through the internal threads.
[0033] Two limiting plates 3 are fixedly connected to the outer wall of the template component 1. The two limiting plates 3 are located above and below the clearance hole 101, respectively. The locking component 202 is set between the two limiting plates 3. The outer diameter of the locking component 3 is set as a rectangular structure. The rectangular structure and the limiting plates 3 cooperate to limit the locking component 3 so that the locking component 3 will not rotate around the pull rod 201.
[0034] The split-type structure design of the locking component allows for quicker installation and removal of the locking component and the pull rod. Only the bolts between the first and second connecting ears need to be installed or removed, making the operation more convenient. Furthermore, by setting limit plates at the upper and lower ends of the locking component, the locking component is prevented from rotating together with the pull rod, achieving relative rotation between the locking component and the pull rod. At the same time, the position design of the limit plates does not hinder the split-type assembly and disassembly of the locking component, and the combination of the two has a better technical effect.
[0035] The template component 1 is arranged in the shape of an arc plate. One end of the template component 1 in the width direction is provided with an installation protrusion 103, and the other end of the template component 1 in the width direction is provided with an installation groove 104. When several template components 1 are combined, the installation protrusion 103 and installation groove 104 provided at both ends of the width of the template component 1 respectively engage with the installation groove 104 and installation protrusion 103 on the adjacent template components 1 on both sides.
[0036] The template component 1 has an integrally formed mounting flange 102 on the outer periphery of its top and bottom ends, and is bolted to the template component 1 in the upper or lower layer of the circular pipe structure through the mounting flange 102; the mounting flange 102 is provided with a positioning bolt hole 1021 that runs longitudinally through the mounting flange 102 and is used for connection and installation.
[0037] In the circumferential direction, adjacent template components are connected by mounting grooves and mounting protrusions to achieve a stable connection structure between each layer of template components; in the longitudinal direction, adjacent template components are bolted together by mounting flanges at the top and bottom of the template components; the overall connection structure of this pile foundation support mold is solid and stable, and has an excellent formwork support effect.
[0038] During installation, this utility model simply requires assembling adjacent template components to form a circular pipe structure. Then, the tie rod is passed through two opposing template components, and locking components are threaded onto both ends of the tie rod. Finally, the tie rod is rotated, causing the two locking components to press the two template components closer together until the template components are locked together with the adjacent template components. After the pile foundation has solidified, the locking components and template components can be removed, and the exposed ends of the tie rod can be cut off.
[0039] Under the action of the traction mechanism, this utility model creates a stable structure with mutual traction between two oppositely arranged template components, preventing the pouring of concrete from prying open the enclosed circular pipe structure or causing the template components to overturn. At the same time, this traction structure can maintain the lateral traction effect throughout the entire process of pile foundation pouring. It does not increase the installation difficulty as the template components increase in height, nor does it affect the lateral support force as the template components increase in height, effectively improving the formwork effect of pile foundation construction.
