Description
Technical Field
[0001] This invention relates to the field of pile cap bottom formwork installation technology, specifically to an integrated electric clamp bottom formwork guiding and positioning mechanism. Background Technology
[0002] A pile cap is a reinforced concrete component that connects a pile foundation to a superstructure (such as a pile cap, column, or wall). Its main function is to effectively and safely transfer and distribute the load from the superstructure to one or more piles below. When using it, the bottom formwork needs to be supported by clamps, and then the pile cap is poured on the bottom formwork.
[0003] As in the prior art, Chinese patent application number CN201922489890.8 discloses a formwork system for a pile foundation with a clamp, including a rock-embedded pile foundation, a steel sleeve, brackets, a bottom formwork, and side formwork. A rock-embedded pile foundation is set within a rock slope. A steel sleeve is pre-embedded at the top of the rock-embedded pile foundation. Brackets are evenly distributed on the outer wall of the steel sleeve. The bottom formwork of the foundation is supported on the brackets. Concrete is poured into the space enclosed by the bottom formwork and the side formwork to form the foundation. The outer diameter of the steel sleeve pre-embedded at the top of the rock-embedded pile foundation is the same as the pile diameter. A connecting rib is provided on the inner wall of the steel sleeve. Pre-drilled holes are provided on the connecting rib. The main reinforcing bars of the steel cage inside the pile pass through the pre-drilled holes and are welded to the connecting rib. A bracket connector is provided on the outer wall of the steel sleeve, and the bracket is installed through the bracket connector.
[0004] For example, in the prior art, Chinese patent application number CN201420646527.7 discloses a bottom formwork support system for a super-large cast-in-place pier at a high-pile wharf, including: pile foundations, steel clamps, main beams, support beams, trusses, and cast-in-place piers; the pile foundations are arranged in two rows longitudinally, respectively arranged at the bottom of the left and right sides of the cast-in-place pier, and the pile foundations on the left and right sides are aligned one by one in the transverse direction; a steel clamp is fixed to the outside of each pile foundation; a set of main beams is provided on the left and right sides horizontally above the steel clamps; a support beam is provided horizontally above the main beams, and a support beam is provided on the front and rear sides of each pile foundation; the truss is horizontally erected on the support beams, and a set of trusses is provided on the two pile foundations horizontally aligned on the left and right sides, and the column bases of the truss are supported and welded to the upper surface of the support beams by a thick steel plate; the cast-in-place pier is horizontally erected on the truss.
[0005] For example, in the prior art, Chinese patent application number CN202510828562.3 discloses a reverse-hanging bottom formwork structure and its installation method for the construction of cast-in-place pile caps at wharves. It belongs to the technical field of wharf construction. The reverse-hanging bottom formwork structure consists of: steel pipe piles, column supports set on the steel pipe piles, transverse steel spreaders set on the columns, a hanging rod system, a limiting system, a supporting main beam structure, and a mold frame for the casting of pile caps. It utilizes the supporting performance of steel pipe piles and uses steel structure to build a reverse-hanging bottom formwork support structure for cast-in-place pile caps, avoiding the defects of the welding construction process of traditional corbel support systems.
[0006] Based on the above information, it can be seen that the traditional pile cap laying process involves first fixing the clamps, then installing the I-beams horizontal and vertical beams, and finally installing timber on the I-beams horizontal and vertical beams. The bottom formwork is then installed on the timber, and the same order is followed when removing the bottom formwork, from top to bottom, which is very cumbersome. Summary of the Invention
[0007] The purpose of this invention is to provide an integrated electric clamp bottom formwork guiding and positioning mechanism to solve the problem of cumbersome construction process mentioned in the background art.
[0008] To achieve the above objectives, the present invention provides the following technical solution:
[0009] An integrated electric clamp bottom formwork guiding and positioning mechanism includes an inclined cast pile. A supporting clamp is installed on the outer side of the upper end of the pile, and a rib plate is placed above the supporting clamp. A bottom formwork is installed above the rib plate. A clamp bearing rib for supporting the rib plate is fixedly welded to the outer side of the supporting clamp. A winding box is fixedly installed on the side of the rib plate. A drive motor outside the winding box drives the clamp guide chain connected to the winding box to wind up the clamp. The drive motor drives the winch inside the winding box to rotate, adjusting the position of the clamp. The supporting clamp is guided by the clamp guide chain. The chain and rib plate form an integrated quick-release structure. The rib plate and the supporting clamp are connected into an integral structure using a clamping guide chain. When installing the bottom formwork, the rib plate and the supporting clamp are hoisted simultaneously using equipment. A clamping wheel for holding the clamping guide chain is installed below the rib plate, and a tensioning mechanism is provided between the clamping wheel and the rib plate. A guide wheel for guiding the clamping guide chain is rotatably installed on the side of the rib plate, and an application sponge for applying lubricating oil to the clamping guide chain is fixedly installed inside the guide wheel. An oil supply mechanism is provided inside the guide wheel.
[0010] Preferably, a connecting ring is fixedly installed at the lower end of the clamp guide chain, and the connecting ring is nested and connected to the clamp hanging ear fixedly installed on the outer surface of the supporting clamp.
[0011] Preferably, the lower surface of the rib plate is fixedly welded with equally spaced limiting blocks, and an engagement groove is formed between adjacent limiting blocks. When the rib plate is connected to the support clamp, the clamp bearing rib is engaged in the engagement groove to form a limiting structure. The clamp bearing rib on the side of the support clamp is engaged in the corresponding engagement groove on the lower surface of the rib plate. The engagement groove restricts the sliding between the support clamp and the rib plate, so that the support clamp will not slide downward under the action of gravity.
[0012] Preferably, the tensioning mechanism includes a guide rod fixedly installed inside the rib plate, and a connecting spring is installed outside the guide rod. The clamping wheel includes a first roller and a second roller corresponding to each other, and the first roller and the second roller are connected by a connecting plate on the side. Under the compression action of the connecting spring, the connecting plate is pressed to move downward. At this time, the connecting plate slides relative to the guide rod through the through hole. Under the clamping action of the first roller and the second roller, the clamping guide chain is clamped, thereby pulling the clamping guide chain downward and reducing the possibility of the clamping guide chain falling off the guide wheel.
[0013] Preferably, the connecting plate has a through hole on its side that connects the upper and lower parts, and the connecting plate and the guide rod form a through sliding structure through the through hole. The oil supply mechanism includes a receiving groove inside the guide wheel, and the guide wheel has a connecting hole on its side wall. The receiving groove is connected to the applicator sponge through the connecting hole. A delivery pipe connected to the receiving groove is rotatably installed on the side of the guide wheel, and the upper end of the delivery pipe is connected to a storage box fixedly installed on the rib. The lubricating oil is delivered to the receiving groove inside the guide wheel through the delivery pipe under its own gravity, and then injected into the applicator sponge through the connecting hole. The applicator sponge absorbs the lubricating oil, and then the applicator sponge is used to apply the lubricating oil to the clamp guide chain to achieve the purpose of lubricating the clamp guide chain and reducing the wear of the clamp guide chain during use.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the integrated guide and positioning mechanism for the electric clamp bottom mold adopts a novel structural design, the specific details of which are as follows:
[0015] 1. The rib plate and the support rib are connected into an integral structure by using a clamp guide chain. When installing the bottom formwork, the rib plate and the support rib are hoisted at the same time by using the equipment, which simplifies the operation steps of the workers and saves time. At the same time, the drive motor drives the winch inside the winding box to rotate and adjust the position of the rib.
[0016] Furthermore, after the clamp position is determined, tighten the clamp guide chain to connect the rib plate and the support clamp. At this time, the clamp bearing rib on the side of the support clamp is inserted into the corresponding engagement groove on the lower surface of the rib plate. The engagement groove restricts the sliding between the support clamp and the rib plate, so that the support clamp will not slide downward under the action of gravity.
[0017] 2. When winding up the clamp guide chain, guide and clamping wheels are used to guide the clamp guide chain, and the connecting plate is squeezed downward under the compression of the connecting spring. At this time, the connecting plate slides relative to the guide rod through the through hole, and clamps the clamp guide chain under the clamping action of the first roller and the second roller, thereby pulling the clamp guide chain downward and reducing the possibility of the clamp guide chain falling off the guide wheel.
[0018] 3. The lubricating oil inside the storage box is transported to the receiving groove inside the guide wheel through the delivery pipe under its own gravity. Then, it is injected into the application sponge through the connection hole. The application sponge absorbs the lubricating oil and then applies the lubricating oil to the clamp guide chain to achieve the purpose of lubricating the clamp guide chain and reducing the wear of the clamp guide chain during use.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Example 1: Please refer to Figures 1-6 To achieve the purpose of electrically adjusting the position of the clamp, this embodiment provides the following technical solution, specifically disclosing: a pile column 1 cast at an incline, a supporting clamp 2 installed on the upper external part of the pile column 1, a rib plate 3 placed above the supporting clamp 2, a bottom template 4 installed above the rib plate 3, a clamp bearing rib 201 for supporting the rib plate 3 fixedly welded to the external side of the supporting clamp 2, and a winding box 5 fixedly installed on the side of the rib plate 3. A drive motor 6 outside the winding box 5 drives the clamp guide chain 7 connected to the winding box 5 to wind up. The supporting clamp 2 and the rib plate 3 form an integrated quick-release structure through the clamp guide chain 7. A connecting hanging ring 8 is fixedly installed at the lower end of the clamp guide chain 7, and the connecting hanging ring 8 is nested and connected with the clamp hanging ear 9 fixedly installed on the outer surface of the supporting clamp 2. A limiting block 13 with equal spacing is fixedly welded to the lower surface of the rib plate 3. A locking groove 14 is formed between adjacent limiting blocks 13. When the rib plate 3 and the supporting clamp 2 are connected, the clamp bearing rib 201 is locked into the locking groove 14 to form a limiting structure.
[0031] When assembling the bottom formwork 4, the rib plate 3 is first hoisted onto the pile 1 using a hoisting device. During the hoisting process, the clamp guide chain 7 is used to hoist the supporting clamp 2 simultaneously (the lower end of the clamp guide chain 7 is equipped with a connecting ring 8, which is nested with the clamp lug 9 on the side of the supporting clamp 2, so that the supporting clamp 2 and the rib plate 3 form a whole and are hoisted simultaneously). The front and rear pieces of the supporting clamp 2 are initially fixed with bolts to form a ring, but it can slide outside the pile 1. Then, the supporting clamp 2 is aligned with the pile 1 and the pile 1 is placed on the outside of the pile 1. At this time, the supporting clamp 2 slides downward outside the pile 1. Then, the workers remotely start the drive motor 6 on the side of the rib plate 3 according to the construction needs. The drive motor 6 drives the winch inside the winding box 5 to rotate. The clamp guide chain 7 is wound up, causing it to pull the support clamp 2 and adjust its position. When the support clamp 2 reaches the designated position, the hoisting device lowers the rib plate 3 while simultaneously winding up the clamp guide chain 7 to keep the support clamp 2 in the same position. After the rib plate 3 is completely placed above the support clamp 2, the clamp bearing rib 201 on the side of the support clamp 2 engages with the engaging groove 14 on the lower surface of the rib plate 3. The engaging groove 14 restricts the lateral sliding of the support clamp 2. Combined with the inclined structure of the pile column 1, the support clamp 2 will not slide downward under gravity, achieving relative fixation. Afterward, the hoisting device is removed, and the workers completely fix the support clamp 2. Finally, the bottom template 4 is installed on the rib plate 3. During this process, the rib plate 3 and the support clamp 2 are installed simultaneously to simplify the steps.
[0032] Example 2: Please refer to Figure 7 In order to reduce detachment, this embodiment provides the following technical solution, specifically: a clamping wheel 11 for clamping the clamping guide chain 7 is installed below the rib plate 3, and a tensioning mechanism is provided between the clamping wheel 11 and the rib plate 3. The tensioning mechanism includes a guide rod 15 fixedly installed inside the rib plate 3, and a connecting spring 16 is installed outside the guide rod 15. The clamping wheel 11 includes a first roller 1101 and a second roller 1102 corresponding to each other. The first roller 1101 and the second roller 1102 are connected by a connecting plate 1103 on the side. The connecting plate 1103 has a through hole 1104 that is connected vertically on the side, and the connecting plate 1103 and the guide rod 15 form a through sliding structure through the through hole 1104.
[0033] During the winding process of the clamp guide chain 7, the guide wheel 10 guides the clamp guide chain 7 to change direction, while the clamping wheel 11 clamps it (the clamping wheel 11 is divided into two parts: the first roller 1101 and the second roller 1102, which are distributed vertically to clamp the clamp guide chain 7). At the same time, the connecting spring 16 outside the guide rod 15 pushes the connecting plate 1103 downward using its own elastic force. At this time, the connecting plate 1103 slides with the guide rod 15 through the through hole 1104 on its inner side, thereby driving the first roller 1101 and the second roller 1102 to move downward, so that the first roller 1101 and the second roller 1102 move the clamp guide chain 7 downward, thereby achieving the purpose of tensioning the clamp guide chain 7 and reducing the possibility of the clamp guide chain 7 falling off the guide wheel 10.
[0034] Example 3: Please refer to Figures 8-9 In order to achieve lubrication and reduce wear, this embodiment provides the following technical solution, which specifically discloses: A guide wheel 10 for guiding the clamp guide chain 7 is rotatably installed on the side of the rib plate 3, and an application sponge 17 for applying lubricating oil to the clamp guide chain 7 is fixedly installed on the inner side of the guide wheel 10. An oil supply mechanism is provided inside the guide wheel 10. The oil supply mechanism includes a receiving groove 18 opened inside the guide wheel 10, and a connecting hole 19 is opened on the side wall of the guide wheel 10. The receiving groove 18 is connected to the application sponge 17 through the connecting hole 19. A delivery pipe 20 connected to the receiving groove 18 is rotatably installed on the side of the guide wheel 10, and the upper end of the delivery pipe 20 is connected to the storage box 12 fixedly installed on the rib plate 3.
[0035] During the hoisting process, the lubricating oil inside the storage box 12 is transported to the receiving groove 18 inside the guide wheel 10 through the delivery pipe 20 under its own gravity. Then, it is injected into the position of the coating sponge 17 through the connection hole 19 opened on the side of the receiving groove 18. The coating sponge 17 absorbs the lubricating oil. When the clamp guide chain 7 is being wound up, the coating sponge 17 is used to apply the lubricating oil to the outside of the clamp guide chain 7, so as to achieve the purpose of lubricating the clamp guide chain 7 and reducing the wear of the clamp guide chain 7.
