Multi-curved template adjustable connecting seat

Abstract

This invention belongs to the field of building construction technology and discloses an adjustable connecting seat for multi-curved formwork, including an adjusting seat assembly and a formwork body, and further including: a connecting assembly, which is installed on the adjusting seat assembly for connecting the adjusting seat assembly and the formwork body; and a fine-tuning assembly, which is set on the top of the connecting assembly.

When the top of the spring telescopic rod becomes the bottom, the T-junction is misaligned with the arc-shaped pipe and the U-shaped pipe respectively, and the connecting column maintains its relative position through the elastic force of the spring telescopic rod. At this time, the included angle of the two formwork bodies is fixed, thus ensuring that operators can flexibly adjust and change the angle as needed.

Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically an adjustable connector for multi-curved templates. Background Technology

[0002] During the casting process of multi-curved structures, templates are required. However, the irregular shape of multi-curved structures is difficult to achieve through direct splicing and requires additional auxiliary components for support. Ideally, these supports should be adjustable to allow the template to better fit the multi-curved structure, resulting in a better casting effect. For indoor applications, such as the interior walls of pools, curved shapes are often used for aesthetic purposes. Typically, operators connect two adjacent wooden planks using hinges, and multiple sets of hinges and planks are used to initially construct the curved outline. After adjustment, the planks connected by hinges need to be fixed with nails to ensure stability. However, once the planks are fixed, adjustments require removing the nails to rotate the planks and adjust the angle between them, which is laborious and restricts flexibility in adjusting the angle. Therefore, to solve these problems, an adjustable connector for multi-curved templates is proposed. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides an adjustable connector for multi-curved templates, which solves the problem that the angle cannot be flexibly adjusted and changed as needed when two wooden boards are connected by hinges for angle adjustment.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an adjustable connecting seat for multi-curved templates, comprising an adjusting seat assembly and a template body, and further comprising: a connecting assembly mounted on the adjusting seat assembly for connecting the adjusting seat assembly and the template body;

[0005] The adjusting seat assembly includes a frame, a piston plate movably connected to the bottom of the frame, a screw rod connected to one side of the piston plate, the screw rod being threaded to the inner wall of the frame and extending one end to the outside of the frame, a U-shaped pipe and an arc-shaped pipe fixedly connected to the frame, an arc-shaped piston rod movably connected inside the arc-shaped pipe, one end of the arc-shaped piston rod extending to the outside of the arc-shaped pipe and connected to a connecting assembly, and a column located above the piston plate movably connected inside the frame, the bottom of the column being bearing connected to... The frame is connected to a connecting column, and an inclined spring telescopic rod is hinged inside the connecting column. The bottom end of the spring telescopic rod is hinged to the inner wall of the frame. A tee port and an L-shaped pipe located above the tee port are opened on one side of the column. The bottom end of the L-shaped pipe is connected to the bottom of the frame. The top end of the L-shaped pipe can be connected to two arc-shaped pipes through the tee port. The arc-shaped pipes, the tee port, the L-shaped pipes and the bottom of the frame are all filled with hydraulic oil. The center of the arc-shaped piston rod and the arc-shaped pipes is the docking point of the two sets of template bodies.

[0006] Initially, the column's downward movement allows the tee opening to be misaligned with the U-shaped pipe and the two sets of arc-shaped pipes, respectively.

[0007] Preferably, the connecting assembly includes a fixed plate fixedly connected to one end of the arc-shaped piston rod, a movable plate movably connected to the fixed plate, a spring combination limiting rod fixedly connected to the movable plate, the rod body of the spring combination limiting rod being movably sleeved inside the fixed plate, and the spring part of the spring combination limiting rod being used to support the tendency of the spring combination limiting rod to move towards another spring combination limiting rod.

[0008] The template body is mounted on the moving plate by screws.

[0009] Preferably, the moving plate is also provided with one-way slots at equal intervals, and an elastic piston rod is also elastically connected inside the arc-shaped piston rod. One end of the elastic piston rod is located inside the arc-shaped pipe and can contact the hydraulic oil inside the arc-shaped pipe. The other end of the elastic piston rod is a one-way inclined block and can be inserted into the one-way slot.

[0010] Preferably, a spring is also provided inside the arc-shaped pipe, and the two ends of the spring are fixedly connected to the arc-shaped pipe and the arc-shaped piston rod, respectively.

[0011] Preferably, an L-shaped pipe is provided at the top of the column, the L-shaped pipe stores hydraulic oil inside, and both ends of the L-shaped pipe are initially blocked by the inner wall of the frame.

[0012] After the L-shaped pipe descends, one end connects to one of the arc-shaped pipes, while the other end is blocked by the inner wall of the frame.

[0013] Preferably, when the spring telescopic rod pushes upward, the tee port is connected to two sets of arc-shaped pipes and one U-shaped pipe respectively; when the spring telescopic rod pushes downward, one end of the L-shaped pipe is connected to one of the arc-shaped pipes, and the other end is blocked by the inner wall of the frame.

[0014] Preferably, the top bearing of the frame is connected to a cap, and four L-shaped pipes are arranged in a circular array on the top of the frame. The cap is elastically connected to an elastic block that can be locked into a slot, and the top of the column is splinedly connected to the cap.

[0015] Preferably, the top of the frame is further provided with a fine-tuning component; the fine-tuning component includes a cavity opened at the top of the frame, a piston plate two is movably connected inside the cavity, a screw two is bearing connected to the top of the piston plate two, the screw two is threadedly connected to the frame and the top end of the screw two extends to the top of the frame;

[0016] The cavity contains hydraulic oil and its bottom is connected to an L-shaped pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The above solution involves leaving a gap at one end of the two sets of template bodies. Rotating the screw pushes the piston plate to move, and the piston plate injects the hydraulic U-shaped pipe and tee port at the bottom of the frame into the arc-shaped pipe. This pushes the arc-shaped piston rod to move, causing the connecting components and template bodies to rotate around the center of the arc-shaped pipe. This adjusts the two sets of connecting components and template bodies respectively. After the angle between the two sets of connecting components and template bodies is adjusted, the column is pressed down and the connecting column is pushed down. When the top of the spring telescopic rod becomes the bottom, the tee port is misaligned with the arc-shaped pipe and the U-shaped pipe respectively. The connecting column will also maintain its relative position unchanged due to the elasticity of the spring telescopic rod. At this time, the angle between the two template bodies is fixed, thus ensuring that the operator can flexibly adjust and change the angle as needed.

[0019] The above solution involves misaligning the tee port with the arc-shaped pipe and the U-shaped pipe respectively. One end of the L-shaped pipe will connect with one of the arc-shaped pipes, while the other end will be blocked by the frame. Then, rotating the cap will cause the column to rotate, allowing one end of the L-shaped pipe to connect with the arc-shaped pipe and the other end of the L-shaped pipe to connect with the U-shaped pipe. At this time, the operator can adjust the angle of one set of template bodies and connecting components by rotating the screw. After the adjustment is completed, the operator can fix the adjusted arc-shaped pipe, connecting components and template body by rotating the cap back to its original position, thereby realizing the individual adjustment of the angle of one set of template bodies.

[0020] The above solution involves bringing the two sets of template bodies into contact at one end. When this happens, the rotation of the connecting component causes the template bodies to rotate synchronously, and the ends of the template bodies that are close to each other are pressed together and then moved away from each other. At this time, the template bodies will drive the moving plate to move away from the other set of template bodies, thus avoiding the situation where the template bodies cannot rotate due to the lack of gap at one end. At the same time, the movement of the moving plate will also cause the one-way slot to compress one end of the elastic piston rod and retract it into the arc-shaped piston rod. After the angle of the template body is adjusted, the elastic piston rod will be reset by its own elastic force and lock into one of the one-way slots, thereby preventing the moving plate from being reset by the elastic force of the spring combination limit rod.

Detailed Implementation

[0031] 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.

[0032] like Figures 1 to 9 As shown, the present invention provides an adjustable connecting seat for a multi-curved template, including an adjusting seat assembly 1 and a template body 3, and further including: a connecting assembly 2, which is installed on the adjusting seat assembly 1 for connecting the adjusting seat assembly 1 and the template body 3;

[0033] Adjustment seat assembly 1 includes a frame 11. A piston plate 12 is movably connected to the bottom of the frame 11. A screw 121 is connected to one side of the piston plate 12 via a bearing. The screw 121 is threaded to the inner wall of the frame 11 and extends to the outside of the frame 11 at one end. A U-shaped pipe 13 and an arc-shaped pipe 16 are fixedly connected to the frame 11. An arc-shaped piston rod 17 is movably connected inside the arc-shaped pipe 16. One end of the arc-shaped piston rod 17 extends to the outside of the arc-shaped pipe 16 and is connected to the connecting assembly 2. A column 14 located above the piston plate 12 is movably connected inside the frame 11. A connecting column is connected to the bottom of the column 14 via a bearing. 142, a spring telescopic rod 1421 in an inclined state is hinged inside the connecting column 142. The bottom end of the spring telescopic rod 1421 is hinged to the inner wall of the frame 11. A three-way pipe 15 and an L-shaped pipe 141 located above the three-way pipe 15 are provided on the column 14. The bottom end of the U-shaped pipe 13 is connected to the bottom of the frame 11. The top end of the U-shaped pipe 13 can be connected to two arc-shaped pipes 16 through the three-way pipe 15. The arc-shaped pipe 16, the three-way pipe 15, the U-shaped pipe 13 and the bottom of the frame 11 are all filled with hydraulic oil. The center of the arc-shaped piston rod 17 and the arc-shaped pipe 16 is the docking point of the two sets of template bodies 3.

[0034] Initially, the downward movement of column 14 causes the tee port 15 to be misaligned with the U-shaped pipe 13 and the two sets of arc-shaped pipes 16 respectively;

[0035] Using the above scheme, by leaving a gap at one end of the two sets of template bodies 3, rotating screw 121 pushes piston plate 12 to move. Piston plate 12 will inject the hydraulic U-shaped pipe 13 and tee port 15 at the bottom of frame 11 into arc-shaped pipe 16, thereby pushing arc-shaped piston rod 17 to move and causing connecting component 2 and template body 3 to rotate around the center of arc-shaped pipe 16 to adjust the two sets of connecting component 2 and template body 3 respectively. After the included angle of the two sets of connecting component 2 and template body 3 is adjusted, press down column 14 and push connecting column 142 down. When the top end of spring telescopic rod 1421 becomes the bottom end, the tee port 15 is misaligned with arc-shaped pipe 16 and U-shaped pipe 13 respectively, and the connecting column 142 will also maintain its relative position unchanged by the elastic force of spring telescopic rod 1421. At this time, the included angle of the two template bodies 3 is fixed, thereby ensuring that the operator can flexibly adjust and change the angle as needed.

[0036] like Figures 1-5 and Figure 8 As shown, the connecting assembly 2 includes a fixed plate 21 fixedly connected to one end of the arc-shaped piston rod 17, a movable plate 22 movably connected to the fixed plate 21, and a spring combination limiting rod 24 fixedly connected to the movable plate 22. The rod body of the spring combination limiting rod 24 is movably sleeved inside the fixed plate 21, and the spring part of the spring combination limiting rod 24 is used to support the tendency of the spring combination limiting rod 24 to move towards another spring combination limiting rod 24.

[0037] The template body 3 is mounted on the moving plate 22 by screws;

[0038] One-way slots 23 are also provided at equal intervals on the moving plate 22. An elastic piston rod 171 is also elastically connected inside the arc-shaped piston rod 17. One end of the elastic piston rod 171 is located inside the arc-shaped pipe 16 and can contact the hydraulic oil inside the arc-shaped pipe 16. The other end of the elastic piston rod 171 is a one-way inclined block and can be inserted into the one-way slot 23.

[0039] The inside of the arc-shaped pipe 16 is also provided with a spring 161, and the two ends of the spring 161 are fixedly connected to the arc-shaped pipe 16 and the arc-shaped piston rod 17 respectively.

[0040] Using the above scheme, by bringing the two sets of template bodies 3 into contact at one end, the rotation of the connecting component 2 will cause the template bodies 3 to rotate synchronously, and the ends of the template bodies 3 that are close to each other will be pressed against each other and moved away from each other. At this time, the template bodies 3 will drive the moving plate 22 to move away from the other set of template bodies 3, so as to avoid the situation where the template bodies 3 cannot rotate because there is no gap at one end. At the same time, the movement of the moving plate 22 will also cause the one-way slot 23 to press one end of the elastic piston rod 171 and retract it into the arc-shaped piston rod 17. After the angle adjustment of the template body 3 is completed, the elastic piston rod 171 will be reset by its own elastic force and locked into one of the one-way slots 23, thereby avoiding the situation where the moving plate 22 will be reset by the spring force of the spring combination limit rod 24.

[0041] It is worth noting that when the arc-shaped piston rod 17 needs to move in the opposite direction, the piston plate 12 moves by rotating the screw 121 in the opposite direction and draws out the hydraulic oil in the arc-shaped pipe 16, the tee port 15 and the U-shaped pipe 13. At this time, the arc-shaped piston rod 17 is supported by the elastic force of the spring 161. The drawing out of the hydraulic oil inside the arc-shaped pipe 16 will first drive the elastic piston rod 171 to disengage from the U-shaped pipe 13, and then the arc-shaped piston rod 17 will retract, thereby adjusting the angle between the connecting assembly 2 and the template body 3 in the opposite direction. At this time, since the elastic piston rod 171 disengages from the one-way slot 23, the moving plate 22 and the template body 3 will move towards the other set of template bodies 3 under the elastic force of the spring part of the spring combination limiting rod 24, thereby ensuring that the opposite ends of the two sets of template bodies 3 can still maintain contact when they rotate in the opposite direction.

[0042] like Figures 3-9 As shown, an L-shaped pipe 141 is provided at the top of column 14. The L-shaped pipe 141 contains hydraulic oil. Both ends of the L-shaped pipe 141 are initially blocked by the inner wall of the frame 11.

[0043] After the L-shaped pipe 141 descends, one end of it connects with one of the arc-shaped pipes 16, and the other end is blocked by the inner wall of the frame 11.

[0044] When the spring telescopic rod 1421 pushes upward, the tee port 15 is connected to two sets of arc-shaped pipes 16 and a U-shaped pipe 13 respectively; when the spring telescopic rod 1421 pushes downward, one end of the L-shaped pipe 141 is connected to one of the arc-shaped pipes 16, and the other end is blocked by the inner wall of the frame 11.

[0045] The top bearing of the frame 11 is connected to a cap 111. Four L-shaped pipes 141 are arranged in a circular array on the top of the frame 11. An elastic block 1111 that can be snapped into the slot 112 is elastically connected to the cap 111. The top of the column 14 is splinedly connected to the cap 111.

[0046] The top of the frame 11 is also provided with a fine adjustment component 4; the fine adjustment component 4 includes a cavity 41 opened on the top of the frame 11, a piston plate 42 is movably connected inside the cavity 41, a screw 43 is connected to the top of the piston plate 42 by a bearing, the screw 43 is threadedly connected to the frame 11 and the top of the screw 43 extends to the top of the frame 11.

[0047] The cavity 41 contains hydraulic oil and its bottom end is connected to the L-shaped pipe 141;

[0048] Using the above scheme, after the tee port 15 is misaligned with the arc-shaped pipe 16 and the U-shaped pipe 13 respectively, one end of the L-shaped pipe 141 will be connected to one of the arc-shaped pipes 16 while the other end is blocked by the frame 11. Then, rotating the cap 111 will drive the column 14 to rotate, so that one end of the L-shaped pipe 141 can be connected to the arc-shaped pipe 16, and the other end of the L-shaped pipe 141 can be connected to the U-shaped pipe 13. At this time, the operator can adjust the angle of one set of template bodies 3 and connecting components 2 by rotating the screw 121. After the adjustment is completed, the operator can fix the adjusted arc-shaped pipe 16, connecting components 2 and template bodies 3 by rotating the cap 111 back to the original position, thereby realizing the individual adjustment of the angle of one set of template bodies 3.

[0049] Meanwhile, since the elastic block 1111 can be inserted into the slot 112, it is also convenient for the operator to judge the accuracy of the rotation position.

[0050] Working principle and usage process of this invention:

[0051] With a gap between the two sets of template bodies 3 at one end, the operator first fixes the frame 11 and connects the template body 3 to the adjusting seat assembly 1 through the connecting assembly 2. The operator rotates the screw 121 to push the piston plate 12 to move. The piston plate 12 will inject the hydraulic U-shaped pipe 13 and the tee port 15 at the bottom of the frame 11 into the arc-shaped pipe 16, thereby pushing the arc-shaped piston rod 17 to move and causing the connecting assembly 2 and the template body 3 to rotate around the center of the arc-shaped pipe 16 to adjust the two sets of connecting assemblies 2 and template bodies 3 respectively. After the angle between the two sets of connecting assemblies 2 and template bodies 3 is adjusted, the column 14 is pressed down and the connecting column 142 is pushed down. When the top end of the spring telescopic rod 1421 becomes the bottom end, the tee port 15 is misaligned with the arc-shaped pipe 16 and the U-shaped pipe 13 respectively, and the connecting column 142 will also maintain its relative position unchanged through the elastic force of the spring telescopic rod 1421. At this time, the angle between the two template bodies 3 is fixed.

[0052] When the tee port 15 is misaligned with the arc-shaped pipe 16 and the U-shaped pipe 13 respectively, one end of the L-shaped pipe 141 will be connected to one of the arc-shaped pipes 16 while the other end is blocked by the frame 11. When it is necessary to adjust the angle of one set of template bodies 3, rotating the cap 111 will drive the column 14 to rotate, which will allow one end of the L-shaped pipe 141 to be connected to the arc-shaped pipe 16, and the other end of the L-shaped pipe 141 to be connected to the U-shaped pipe 13. At this time, the operator can adjust the angle of one set of template bodies 3 and the connecting component 2 by rotating the screw 121. After the adjustment is completed, the operator can fix the adjusted arc-shaped pipe 16, connecting component 2 and template body 3 by rotating the cap 111 back to its original position.

[0053] When there is no gap between the two sets of template bodies 3 at one end, the rotation of the connecting component 2 will cause the template bodies 3 to rotate synchronously, and the ends of the template bodies 3 that are close to each other will be pressed against each other and moved away from each other. At this time, the template bodies 3 will drive the moving plate 22 to move away from the other set of template bodies 3, so as to avoid the situation where the template bodies 3 cannot rotate because there is no gap between the two ends. At the same time, the movement of the moving plate 22 will also cause the one-way slot 23 to press one end of the elastic piston rod 171 and retract it into the arc-shaped piston rod 17. After the angle adjustment of the template body 3 is completed, the elastic piston rod 171 will be reset by its own elastic force and locked into one of the one-way slots 23, thereby preventing the moving plate 22 from being reset by the spring force of the spring combination limit rod 24.

[0054] When the arc-shaped piston rod 17 needs to move in the opposite direction, the piston plate 12 moves by rotating the screw 121 in the opposite direction and draws out the hydraulic oil in the arc-shaped pipe 16, the tee port 15 and the U-shaped pipe 13. At this time, the arc-shaped piston rod 17 is supported by the elastic force of the spring 161. The drawing out of the hydraulic oil in the arc-shaped pipe 16 will first drive the elastic piston rod 171 to disengage from the U-shaped pipe 13, and then the arc-shaped piston rod 17 will retract, thereby adjusting the angle between the connecting assembly 2 and the template body 3 in the opposite direction. At this time, since the elastic piston rod 171 disengages from the one-way slot 23, the moving plate 22 and the template body 3 will move towards the other set of template bodies 3 under the elastic force of the spring part of the spring combination limiting rod 24, thereby ensuring that the opposite ends of the two sets of template bodies 3 can still maintain contact when they rotate in the opposite direction.
