Description

Technical Field

[0001] This utility model relates to the field of caisson template technology, specifically a caisson template splicing structure. Background Technology

[0002] The field of caisson formwork technology mainly involves the prefabrication process of concrete caissons in water conservancy projects, port construction, bridge foundations, and underwater structures. The core of this technology lies in the precise control of the concrete pouring process through a formwork system, forming caisson components with specific structural strength and watertightness requirements. The caisson formwork splicing structure refers to a specialized formwork system that uses modular units and high-precision connection mechanisms for rapid assembly. This structure optimizes the splicing node construction, achieving multi-directional adjustable connections while ensuring formwork rigidity.

[0003] Existing technologies rely on high-precision machining of modular units and rigid connection mechanisms, resulting in limited freedom of adjustment at splicing nodes and difficulty in adapting to minor deformations caused by uneven foundation settlement or concrete shrinkage. Multi-directional adjustable connection mechanisms typically use bolt fastening, requiring point-by-point adjustment and locking during installation, which is cumbersome and prone to misalignment due to human error. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a caisson template splicing structure, which solves the problem that the current reliance on high-precision processing and rigid connection mechanisms of modular units results in limited freedom of adjustment of splicing nodes, making it difficult to adapt to minor deformations caused by uneven foundation settlement or concrete shrinkage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a caisson template splicing structure, including a base plate, first side plates installed on both sides of the base plate, second side plates installed at both ends of the base plate, a plurality of first fixing plates fixedly connected to the upper surface of the base plate, second fixing plates fixedly connected to the outer walls of the first and second side plates, a connector slidably connected to the inner walls of the first and second fixing plates, the lower surface of the connector slidably connected to the inner wall of the first fixing plate, the side surface of the connector slidably connected to the inner wall of the second fixing plate, and the shape of the connector is triangular.

[0006] As a preferred technical solution of this utility model, the upper surface of the connector is provided with a first screw hole, the inner wall of the first screw hole is threaded with a first screw, and the first screw hole extends into the interior of the base plate.

[0007] As a preferred embodiment of this utility model, the side of the connector is provided with a second screw hole, which extends into the interior of the first side plate and the second side plate.

[0008] As a preferred technical solution of this utility model, a first fixing hole is provided on the upper surface of the first side plate and the second side plate, and a first fixing rod is threaded into the first fixing hole.

The second fixing hole passes through the base plate, the first side plate and the second side plate.

[0010] As a preferred technical solution of this utility model, the outer walls of the base plate, the first side plate, and the second side plate are coated with a waterproof coating.

[0011] Compared with the prior art, this utility model provides a caisson template splicing structure, which has the following characteristics:

[0012] Beneficial effects:

[0013] 1. This caisson template splicing structure employs a combination of fixed plates and sliding connectors between the bottom plate and side plates. Triangular connectors are embedded within multiple fixed plates, utilizing their geometric properties to enhance the load-bearing capacity against lateral forces. Simultaneously, a bidirectional sliding path between the connectors and fixed plates enables rapid positioning of the side plates and bottom plate. The sliding mechanism of the connectors within the fixed plates allows for multi-angle fine-tuning of the side plates along the bottom plate plane, ensuring a tight fit during splicing. When subjected to lateral concrete pressure, the inclined structure of the triangular connectors decomposes the horizontal load into vertical reaction forces with the bottom plate, reducing the risk of deformation at the connection nodes due to stress concentration. The combined design of the fixed plates and connectors creates redundant constraints, suppressing displacement at the splicing points under vibration conditions and improving the overall rigidity of the template. This structure, while ensuring detachability, significantly reduces manual calibration time through optimized mechanical transmission paths and multi-degree-of-freedom adjustment functions, avoiding grout leakage or dimensional deviations caused by template misalignment. It also reduces the reliance of the support structure on heavy lifting equipment, adapting to the high-precision prefabrication requirements of complex cross-section caissons.

[0014] 2. This caisson formwork splicing structure achieves precise positioning and rigid fixation of the bottom and side plates in three dimensions by setting threaded holes through the bottom and side plates on the upper and side surfaces of the connectors, respectively. Combined with the bidirectional locking mechanism of the threaded connectors, the second threaded hole on the side of the connector penetrates the interior of the side plate, forming an additional constraint perpendicular to the splicing surface, effectively suppressing the relative displacement between the side plate and the bottom plate during concrete pouring. The first fixing hole on the upper surface of the side plate cooperates with the through-type fixing rod to form a continuous tensile force transmission path at the top of the formwork, reducing the risk of splice cracking due to localized stress concentration. The second fixing hole on the side of the bottom plate... The fixed holes penetrate the multi-layer structure, and the pre-tightening force is applied through long bolts to enhance the overall bending stiffness of the formwork. The waterproof coating on the outer wall reduces the corrosion of the metal formwork by concrete moisture penetration, extending the number of uses. The threaded connection replaces the traditional welding or pin structure, making the assembly and disassembly process reversible and without special tools, shortening the time for formwork assembly and disassembly. The multi-level through-hole design forms redundant fixing points, maintaining the joint sealing under tidal loads or vibration conditions, avoiding surface defects of the caisson caused by grout leakage. The bolt holes extend into the interior of the structure to ensure that the connectors and the formwork body form a mechanical interlock, improving the shear resistance of the nodes.

[0019] 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, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-3In this embodiment: a caisson template splicing structure includes a base plate 1, first side plates 2 are installed on both sides of the base plate 1, second side plates 3 are installed at both ends of the base plate 1, a plurality of first fixing plates 4 are fixedly connected to the upper surface of the base plate 1, second fixing plates 5 are fixedly connected to the outer walls of the first side plates 2 and the second side plates 3, and connectors 6 are slidably connected to the inner walls of the first fixing plates 4 and the second fixing plates 5. The lower surface of the connector 6 is slidably connected to the inner wall of the first fixing plate 4, and the side of the connector 6 is slidably connected to the inner wall of the second fixing plate 5. The connector 6 is triangular in shape.

[0022] In this embodiment, the installation method of using fixed plates and sliding connectors 6 between the base plate 1 and the side plate is adopted. Triangular connectors 6 are embedded inside multiple fixed plates. Their geometric characteristics enhance the bearing capacity against lateral forces. At the same time, the bidirectional sliding path between the connectors 6 and the fixed plates enables the rapid positioning of the side plates and the base plate 1. The sliding mechanism of the connectors 6 on the inner wall of the fixed plates allows the side plates to be finely adjusted at multiple angles along the plane of the base plate 1, ensuring a tight fit of the joints during the splicing process. When the triangular connectors 6 are subjected to the lateral pressure of concrete, their inclined structure decomposes the horizontal load into a reaction force perpendicular to the base plate 1, reducing the risk of deformation caused by stress concentration at the connection nodes. The combined design of the fixed plates and connectors 6 forms redundant constraints, suppressing the displacement of the splicing parts under vibration conditions and improving the overall rigidity of the template. This structure, while ensuring disassembly, significantly reduces the manual calibration time through mechanical transmission path optimization and multi-degree-of-freedom adjustment functions, avoiding grout leakage or dimensional deviation caused by template misalignment. At the same time, it reduces the dependence of the support structure on heavy lifting equipment and adapts to the high-precision prefabrication requirements of complex cross-section caissons.

[0023] Preferably, the upper surface of the connector 6 is provided with a first screw hole 7, the inner wall of the first screw hole 7 is threaded with a first screw 8, the first screw hole 7 is opened to the interior of the base plate 1, and the side of the connector 6 is provided with a second screw hole 9, the second screw hole 9 is opened to the interior of the first side plate 2 and the second side plate 3.

[0024] Among them, by setting screw hole structures that penetrate the bottom plate 1 and the side plate on the upper surface and side of the connector 6 respectively, combined with the bidirectional locking mechanism of the threaded connector 6, the bottom plate 1 and the side plate are accurately positioned and rigidly fixed in three dimensions. The second screw hole 9 on the side of the connector 6 penetrates the interior of the side plate, forming an additional constraint perpendicular to the splicing surface, which effectively suppresses the relative displacement between the side plate and the bottom plate 1 during the concrete pouring process.

[0025] Preferably, a first fixing hole 11 is provided on the upper surface of the first side plate 2 and the second side plate 3, and a first fixing rod 12 is threaded into the first fixing hole 11. The first fixing hole 11 passes through the first side plate 2 and the second side plate 3.

[0026] The first fixing hole 11 on the upper surface of the side plate cooperates with the through fixing rod to form a continuous tensile force transmission path at the top of the template, reducing the risk of cracking of the splice joint due to local stress concentration.

[0027] Furthermore, a second fixing hole 13 is provided on one side of the base plate 1, and a second fixing rod 14 is threadedly connected to the inner wall of the second fixing hole 13. The second fixing hole 13 passes through the base plate 1, the first side plate 2 and the second side plate 3.

[0028] Among them, the second fixing hole 13 on the side of the base plate 1 penetrates the multi-layer structure. The pre-tightening force is applied by the long bolt to enhance the bending stiffness of the overall template. The threaded connection replaces the traditional welding or pin structure, making the disassembly and assembly process reversible and without special tools, shortening the time for template assembly and disassembly. The multi-level through fixing hole design forms redundant fixing points, maintaining the joint sealing under tidal load or vibration conditions, avoiding surface defects of the caisson caused by grout leakage. The bolt hole depth extends into the interior of the structure to ensure that the connector 6 and the template body form a mechanical interlock, improving the shear resistance of the node.

[0029] Furthermore, the outer walls of the base plate 1, the first side plate 2, and the second side plate 3 are coated with a waterproof coating 15.

[0030] Among them, the outer wall waterproof coating 15 reduces the corrosion of metal formwork by concrete moisture penetration and extends the number of times it can be reused.

[0031] The working principle and usage process of this utility model are as follows: The working principle utilizes the mechanical interlocking and multi-level constraint mechanism of modular units. Connector 6, base plate 1, and side plates form a three-dimensional threaded connection network through through-hole bolts. The axial preload of the bolts rigidly fixes each component, generating normal pressure at the joint surface of the side plate and base plate 1 to enhance frictional constraint. The first fixing rod 12 on the upper surface of the side plate penetrates the side plate and applies vertical tension, counteracting the buoyancy and lateral pressure during concrete pouring. The second fixing rod 14 on the side of the base plate 1 spans multiple layers, forming a continuous bending section through multi-point preload, improving the overall stability of the formwork. The waterproof coating 15 forms a dense isolation layer on the metal surface, blocking the penetration path of moisture and concrete slurry, reducing corrosion and adhesion to the formwork. The bolt holes extend into the interior of the formwork, creating a mechanical interlock between connector 6 and the base material, ensuring that the nodes maintain geometric accuracy under dynamic loads.

[0032] The procedure is as follows: Place the base plate 1 horizontally, and install the first side plate 2 and the second side plate 3 vertically on both sides and ends of the base plate 1 respectively. Initially align the splicing surfaces of each module, embed the connector 6 into the inner wall of the first fixing plate 4 of the base plate 1 and the second fixing plate 5 of the side plate, adjust by sliding to align the first screw hole 7 of the connector 6 with the internal hole of the base plate 1, and screw in the first screw 8 to achieve initial fixation of the base plate 1 and the connector 6. Then, align the second screw hole 9 on the side of the connector 6 with the hole inside the side plate, screw in the second screw 10 to complete the lateral locking, screw in the first fixing hole 11 on the upper surface of the side plate to make it pass through the two side plates and apply vertical tension; install the second fixing rod 14 in the second fixing hole 13 on the side of the bottom plate 1, spanning the bottom plate 1 and the two side plates to form a horizontal constraint, check the tightness of all screw holes and fixing rods, confirm that there are no visible gaps at the splicing surface, and apply a waterproof coating 15 to the joint if necessary, pour concrete in layers and vibrate simultaneously, monitor the deformation of the template in real time, and maintain the structural dimensional accuracy by adjusting the pre-tightening force of the fixing rods. After pouring, unscrew all screws and fixing rods in reverse, separate the side plate from the bottom plate 1, remove the concrete residue on the surface, check the integrity of the waterproof coating 15 and apply it to the damaged parts, and store the template units by category.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
