Description

Technical Field

[0001] This utility model relates to the field of caisson technology, and in particular to a caisson core mold structure. Background Technology

[0002] Conventional core mold structures are large, monolithic steel templates. Modifying them to use different sized core molds requires gas welding, cutting, assembling, and re-welding to create the new template. Conventional core molds have poor versatility, low modification efficiency, complex construction, and a high template cutting loss rate. Therefore, modifying conventional templates requires a large investment of steel and personnel, resulting in high secondary modification costs. Existing core membrane structures are designed so that each template can expand and contract independently, thereby improving the versatility of the core membrane template, such as the combined caisson core mold described in patent number CN209260741U. This involves setting the core membrane as a composite template spliced ​​together, with opposing templates connected by a spiral adjustment rod to adjust the spacing between them. However, this patent has a drawback: after adjusting the template spacing, gaps remain between adjacent templates. During later pouring, concrete cannot be prevented from flowing into the core membrane through these gaps, leading to low caisson pouring efficiency and affecting the integrity of the caisson's internal formation. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art where combined caisson formwork cannot solve the issue of concrete flowing into the core membrane through the gap between adjacent formworks after the formwork gap is adjusted, and to provide a caisson core mold structure.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A caisson core mold structure includes four main templates, with two adjacent main templates connected by a bracket, and each bracket being detachably connected to a main template.

[0006] It also includes a support frame, with the main template connected to each of the four sides of the support frame. The support frame and the main template in the corresponding direction are connected by telescopic components, which are used to control the main template to move toward or away from the support frame.

[0007] This utility model relates to a caisson core mold structure. A support frame is installed, with each side of the support frame connected to the corresponding main template via telescopic components. These components allow the main template to move towards or away from the support frame, thereby adjusting the size of the core mold obtained by splicing the main templates. A bracket is installed between adjacent main templates, and this bracket is detachably connected to the main template, allowing the main templates to be reconnected via the bracket after movement. This invention ensures that no gaps appear between adjacent main templates after movement, preventing concrete from flowing into the core mold during subsequent pouring and guaranteeing the quality of the caisson pouring.

[0008] As a preferred embodiment of this utility model, the main template includes an inner plate, one side of which is connected to the support frame and the other side is connected to a panel. Mounting seats are provided at both ends of the main template, and the mounting seats are used to connect the support frame.

[0009] By setting the main formwork to be a combination of inner plate and outer plate, the structural strength of the entire main formwork is improved, and the deformation of the main formwork is avoided when the concrete applies force to the main formwork during the later pouring process, thus ensuring the quality of the caisson forming in the later stage.

[0010] As a preferred embodiment of this utility model, a gap is provided between the panel and the inner panel, and a plurality of connectors are arranged at intervals in the gap. One end of each connector is connected to the panel and the other end is connected to the inner panel.

[0011] By creating a gap between the inner panel and the outer panel, and by installing several connectors within the gap to connect the inner panel and the outer panel, the overall rigidity and deformation resistance of the formwork are effectively improved, ensuring structural stability during concrete pouring. The connectors, spaced apart within the gap, help to evenly distribute the stress between the outer panel and the inner panel, reduce local stress concentration, and lower the risk of local bulging or warping of the panel due to uneven load.

[0012] As a preferred embodiment of this utility model, the mounting base includes an inclined plate, one end of which is connected to the panel, and the inclined plate is inclined in the direction of the support frame. A reinforcing member is provided on the side of the inclined plate facing the panel, one end of which is connected to the panel and the other end of which is connected to the inclined plate.

[0013] The inclined plate is connected to the panel at a certain angle to form a stable triangular structure, which has good shear and bending resistance, reducing deformation caused by uneven stress during installation. The inclined plate is oriented towards the support frame, making it easier to fix the adjacent main template when installing the clamping frame. Reinforcing parts are also provided to improve the overall strength of the mounting base and structure, preventing structural damage to the entire mounting base when installing the bracket later.

[0014] As a preferred embodiment of this utility model, the panel has a groove on the side facing the support frame.

[0015] By creating grooves on the panel, when the panel is subsequently clamped by the clamping part, the second clamping plate can fit against the panel through the side wall of the groove, increasing the contact area between the second clamping plate and the panel and improving the stability of clamping.

[0016] As a preferred embodiment of this utility model, the bracket includes a first clamping plate and a second clamping plate, and a locking component is provided between the first clamping plate and the second clamping plate. The first clamping plate abuts against the inclined plate, and the second clamping plate abuts against the side wall of the groove. The locking component is used to fix the relative distance between the first clamping plate and the second clamping plate to achieve clamping of the panel.

[0017] The locking components between the first and second clamping plates can effectively fix the relative distance between them, forming a stable clamping force to ensure that the panel will not loosen or shift during construction, thus improving the reliability of the overall structure. By adjusting the locking components, the distance between the clamping plates can be quickly changed to adapt to panels of different thicknesses or specifications, greatly improving the versatility and construction efficiency of the template system.

[0018] As a preferred embodiment of this utility model, the height of the support is the same as the height of the main template.

[0019] As a preferred embodiment of this utility model, the second clamping plate is provided with a through hole for installing the locking component.

[0020] By setting a pass-through on the second clamping plate, it is convenient to install locking components to clamp the main template later.

[0021] As a preferred embodiment of this utility model, the locking component includes a sleeve and a guide rod, one end of the guide rod being fixedly connected to the side of the first clamping plate facing the support frame, and the other end being threadedly connected to the sleeve;

[0022] The sleeve is movably connected to the second clamping plate through the through hole, and a limiting nut is provided at the end of the sleeve away from the guide rod. The limiting nut abuts against the side of the second clamping plate facing the support frame.

[0023] The threaded connection design between the sleeve and the guide rod achieves a highly efficient locking effect. Utilizing the self-locking property of the thread, the connection remains stable under stress, preventing loosening due to vibration or external forces and improving the overall structural stability. The setting of the limit nut further enhances the locking effect, effectively preventing loosening even under high-frequency construction operations or heavy loads, ensuring the long-term reliable operation of the formwork system. The combination of the guide rod and the sleeve simplifies the cumbersome steps of traditional bolted connections between main formwork panels. Locking or loosening can be completed simply by rotating the sleeve, greatly improving construction efficiency and making it particularly suitable for formwork structures that require frequent disassembly and assembly.

[0024] As a preferred embodiment of this utility model, the body of the reinforcing component is an L-shaped steel structure.

[0025] As a preferred embodiment of this utility model, the caisson core mold structure further includes a base, a base panel is provided around the base, and the top of the base is fixedly connected to the support frame.

[0026] The fixed connection between the base and the support frame forms a solid foundation support system, which effectively disperses the vertical and horizontal loads generated by the core mold during construction and prevents the structure from tilting or shifting due to uneven stress.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0028] 1. This utility model is a caisson core mold structure. By setting a support frame, each side of the support frame is connected to the main template in the corresponding direction through a telescopic component. The telescopic component can drive the main template to move toward or away from the support frame, thereby adjusting the size of the core mold obtained by splicing the main templates. Furthermore, a bracket is set between two adjacent main templates, and the bracket is detachably connected to the main template, so that the main template can be reconnected through the bracket after being moved. This application can ensure that there will be no gap between adjacent main templates after the main template is moved, so that concrete will not flow into the core mold through the gap during subsequent pouring, thus ensuring the quality of caisson pouring.

[0045] Example 1

[0046] like Figure 1 , Figure 2 and Figure 3 The caisson core mold structure shown includes a frame formed by four main templates 1. A bracket 2 is provided between two adjacent main templates 1, and the bracket 2 is detachably connected to the main template 1. The bracket 2 connects two adjacent main templates 1. The caisson core mold structure includes a support frame 3. Each side of the support frame 3 is connected to the corresponding main template 1 through a telescopic member 4. Each main template 1 can move toward or away from the support frame 3 through the telescopic member 4.

[0047] When the caisson core mold structure needs to be adjusted in size, the construction workers loosen the support 2, so that the connection between the adjacent main mold 1 is released. Then, the corresponding connected main mold 1 is moved by the telescopic component 4. After the movement is completed, the construction workers connect the two adjacent main molds 1 through the support 2 and fill the gap between the adjacent main molds 1.

[0048] In one or more embodiments, the main template 1 is formed by an inner plate 12 and a front panel 13. One side of the inner plate 12 is connected to the support frame 3, and the side of the inner plate 12 away from the support frame 3 is connected to the front panel 13. By setting the main template 1 to be formed by combining the inner plate 12 and the front panel 13, the structural strength of the entire main template 1 is improved, and the deformation of the main template 1 is avoided after the concrete applies force to the main template 1 during the later pouring process, thus ensuring the quality of the caisson forming in the later stage.

[0049] Furthermore, the inner plate 12 and the outer plate 13 are connected by several spaced connectors 15, and the body of the connector 15 is a channel steel structure. The connectors 15 create a gap 14 between the inner plate 12 and the outer plate 13, which buffers the stress on the outer plate 13 during subsequent pouring, effectively improving the overall rigidity and deformation resistance of the main formwork 1, and ensuring structural stability during concrete pouring. Figure 4 As shown.

[0050] In one or more embodiments, the main template 1 is provided with mounting seats 11 at both ends. Each mounting seat 11 includes an inclined plate 111. One end of the inclined plate 111 is connected to one end of the panel 13, and the inclined plate 111 is inclined towards the support frame 3. A reinforcing member 112 is provided between the side of the inclined plate 111 facing the panel 13 and the panel 13. One end of the reinforcing member 112 is connected to one end of the panel 13, and the other end is connected to the inclined plate 111. The inclined plate 111 and the panel 13 are connected at a certain angle, forming a stable triangular structure with good shear and bending resistance, reducing deformation caused by uneven stress during installation. Furthermore, the inclined direction of the inclined plate 111 is set towards the support frame 3, making it easier to fix adjacent main templates 1 when the subsequent clamping frame is installed. The reinforcing member 112 also improves the overall strength of the mounting seat 11 and prevents structural damage to the entire mounting seat 11 when the bracket 2 is subsequently installed. Figure 5 As shown.

[0051] In one or more embodiments, the panel 13 has a groove 131 on the side facing the support frame 3. By opening the groove 131 on the panel 13, when the panel 13 is clamped by the clamping part, the second clamping plate 22 can fit against the panel 13 through the side wall of the groove 131, thereby increasing the contact area between the second clamping plate 22 and the panel 13 and improving the stability of clamping.

[0052] In one or more embodiments, the bracket 2 includes a first clamping plate 21 and a second clamping plate 22, with a locking component 23 between the first clamping plate 21 and the second clamping plate 22. The first clamping plate 21 abuts against the inclined plate 111, and the second clamping plate 22 abuts against the side wall of the groove 131. The locking component 23 is used to fix the relative distance between the first clamping plate 21 and the second clamping plate 22 to clamp the panel 13. The locking component 23 between the first clamping plate 21 and the second clamping plate 22 can effectively fix the relative distance between them, forming a stable clamping force, ensuring that the panel 13 will not loosen or shift during construction, improving the reliability of the overall structure. By adjusting the locking component 23, the distance between the first clamping plate 21 and the second clamping plate 22 can be quickly changed to adapt to panels 13 of different thicknesses or specifications, greatly improving the versatility and construction efficiency of the template system.

[0053] Furthermore, the second clamping plate 22 is provided with a through hole 221 for installing the locking component 23. The through hole 221 facilitates the subsequent installation of the locking component 23 to clamp the main template 1. The locking component 23 includes a sleeve 231 and a guide rod 232. One end of the guide rod 232 is fixedly connected to the side of the first clamping plate 21 facing the support frame 3, and the other end is threadedly connected to the sleeve 231. The sleeve 231 is movably connected to the second clamping plate 22 through the through hole 221, and a limiting nut 233 is provided at the end of the sleeve 231 away from the guide rod 232. The limiting nut 233 is connected to the side of the second clamping plate 22 facing the support frame 3. The threaded connection between sleeve 231 and guide rod 232 achieves a highly efficient locking effect. Utilizing the self-locking property of the threads, the connection remains stable under stress, preventing loosening due to vibration or external forces and improving the overall structural stability. The limiting nut 233 further enhances the locking effect, effectively preventing loosening even under high-frequency construction operations or heavy loads, ensuring the long-term reliable operation of the formwork system. The combination of guide rod 232 and sleeve 231 simplifies the assembly and disassembly of the support; simply rotating sleeve 231 completes locking or loosening, significantly improving construction efficiency. This is particularly suitable for formwork structures requiring frequent assembly and disassembly, such as... Figure 6 , Figure 7 and Figure 8 As shown.

[0054] In one or more embodiments, the body of the reinforcement 112 is an L-shaped steel structure.

[0055] In one or more embodiments, the caisson core mold structure further includes a base 5, with a base panel 51 covering the periphery of the base 5. The top of the base 5 is fixedly connected to the support frame 3. The fixed connection between the base 5 and the support frame 3 forms a robust foundation support system, effectively distributing the vertical and horizontal loads generated by the core mold during construction and preventing the structure from tilting or displacing due to uneven stress. Figure 9As shown.

[0056] 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.
