Abstract
Description
Technical Field
[0001] This application relates to the field of building construction technology, and in particular to an integrated formwork structure and its construction method. Background Technology
[0002] When constructing a cast-in-place concrete structure, concrete formwork is required. Concrete is poured into the formwork, and the formwork is removed after the concrete has reached its strength. Support frame engineering refers to the temporary reinforcement and support provided to the formwork during pouring, primarily to bear the construction load, and is removed after the concrete has cured.
[0003] Currently, domestic formwork supports generally adopt steel pipe coupler type support frames, which are mainly scaffolding systems constructed by combining building couplers and steel pipes. Before the construction of cast-in-place concrete floor slabs, the formwork is usually manually fixed to the support frame with bolts.
[0004] However, in actual construction, the existing installation method requires construction workers to rely on their construction experience to fix multiple templates on the support frame using bolts and other connecting components, and guide the multiple templates to be arranged neatly, which is time-consuming and labor-intensive, reducing the installation efficiency of the templates. Summary of the Invention
[0005] The purpose of this application is to address the problem that existing installation methods require construction workers to rely on their experience to fix multiple templates onto a support frame using bolts and other connecting components, and to guide the templates to be arranged neatly, which is time-consuming, labor-intensive, and reduces the efficiency of template installation. This application provides an integrated formwork structure and its construction method.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] An integrated formwork structure includes a supporting steel pipe. One end of the supporting steel pipe is fixedly connected to a pair of connecting discs. One end of each connecting disc has a slot symmetrically formed. An L-shaped rod is inserted into the slot. One end of each L-shaped rod is fixedly connected to an abutment rod. A locking disc is rotatably connected inside the slot. One end of the locking disc has a locking slot and a fixing slot. A storage groove is formed on the inner side of the slot. A fixing block adapted to the fixing slot is installed inside the storage groove. One end of each L-shaped rod is fixedly connected to a template. Ejection components are symmetrically installed on one end of each connecting disc.
[0008] By adopting the above technical solution, and by setting up the locking disc and locking port, the abutment rod, the fixed bayonet, the fixed block, and the ejector assembly to work together, it is convenient to drive the ejector assembly to drive the fixed block to insert into the fixed bayonet when the L-shaped insert rod is inserted into the slot. At the same time, the abutment rod is fixedly engaged in the slot, which facilitates the quick engagement and fixation between the template and the connecting plate, effectively improving the installation efficiency of the template.
[0009] Furthermore, the ejection assembly includes an operating chamber located inside the connecting plate. A compression plate is slidably connected inside the operating chamber. A traction rod is fixedly connected to one end of the compression plate. An ejection spring is sleeved on one end of the traction rod. One end of the ejection spring is fixedly connected to the compression plate. One end of the traction rod is fixedly connected to a fixing block. The other end of the traction rod passes through the connecting plate and is fixedly connected to a traction handle.
[0010] By adopting the above technical solution, and through the coordinated use of the ejector spring, compression plate, traction rod, and fixing block, when the traction L-shaped insert rod drives the abutment rod into the slot, the abutment rod pushes the lock disc to align the fixing slot with the fixing block. Then, the springback characteristic of the ejector spring ejects the compression plate, causing the compression plate to push one end of the fixing block into the fixing slot, thereby completing the fixing connection between the lock disc and the connecting disc. This facilitates fixing the abutment rod inside the slot and allows for quick installation of the template. Similarly, when it is necessary to release the lock disc, the traction handle drives the compression plate to compress the ejector spring, causing it to contract and deform. At the same time, the traction rod drives one end of the fixing block to disengage from the fixing slot, thus releasing the locking connection of the lock disc and improving the practicality of the device.
[0011] Furthermore, a safety groove is provided at one end of the connecting plate, and the traction handle is installed inside the safety groove.
[0012] By adopting the above technical solution and using the safety groove in conjunction with the traction handle, the accidental activation of the traction handle by external force is effectively reduced, thus improving the safety of the device.
[0013] Furthermore, the connecting plate has symmetrically opened ejector grooves at one end near the template, and an ejector block is slidably connected inside the ejector groove. One end of the locking plate is fixedly connected to an abutment block, and the abutment block abuts against the ejector block.
[0014] By adopting the above technical solution, and by setting the ejector block and the abutment block to work together, it is convenient to drive the safety groove to drive the abutment block and the ejector block to abut against each other while the abutment rod is inserted into the slot, and push one end of the ejector block to abut against the outside of the template. This improves the alignment between two horizontally adjacent templates and further enhances the practicality of the device.
[0015] Furthermore, a positioning block is fixedly connected to the bottom of the template, and a positioning groove adapted to the positioning block is provided on the top of the template.
[0016] By adopting the above technical solution, and by setting the positioning block and positioning groove to work together, the positioning block can be inserted into the positioning groove, which can drive the vertical adjacent templates to align and improve the connection strength between the vertical adjacent templates.
[0017] Furthermore, a rubber pad is fixedly connected inside the positioning groove, and the positioning block is inserted into the rubber pad.
[0018] By adopting the above technical solution, and by setting the rubber pad in conjunction with the positioning groove and positioning block, it is convenient to guide the positioning block to be inserted into the positioning groove while squeezing the rubber pad to produce deformation, and use the rubber pad to fill the gap between the positioning block and the positioning groove, thereby improving the sealing between two vertically adjacent templates.
[0019] Furthermore, a hollow groove is provided on one side of the template, and a reinforcing rib is fixedly connected inside the hollow groove.
[0020] By adopting the above technical solution, and through the combined use of hollowed-out grooves and reinforcing ribs, the self-weight of the template is effectively reduced while maintaining the template support strength, making it easier to guide the template during installation and improving the practicality of the device.
[0021] A method for integrated formwork construction, comprising the following steps:
[0022] S1: First, the L-shaped insert rod and the abutment rod are inserted into the slot by the traction template, and the abutment rod pushes the lock plate to rotate around the joint axis. At the same time, the lock plate drives the lock mouth to lock the abutment rod into the slot.
[0023] S2: While completing the above S1 operation, the locking disc drives the fixed slot to align with the storage slot, and the ejection spring releases the compression plate to push it out, so that the compression plate drives one end of the fixed block to be inserted into the inside of the fixed slot, thereby completing the locking and fixing of the locking disc.
[0024] S3: While performing the above S2 operation, the locking disc causes the contact block to come into contact with one end of the ejector block, and the contact block pushes the ejector block to move outward along the length of the ejector groove, so that one end of the ejector block comes into contact with the outside of the template.
[0025] S4: After completing the above S3 operation, wait for the concrete to solidify, then manually pull the traction handle to cause the compression plate to squeeze the spring and generate a contraction deformation. At the same time, the traction rod will cause one end of the fixed block to disengage from the inside of the fixed slot. Then, manually pull the L-shaped insert rod to drive the abutment rod to push the lock plate so that the opening of the lock slot faces upward, and guide the abutment rod to disengage from the inside of the slot.
[0026] In summary, this application includes at least one of the following beneficial effects:
[0027] 1. By setting up the locking disc and locking port, the abutment rod, the fixed bayonet, the fixed block, and the ejector assembly, it is easy to drive the ejector assembly to drive the fixed block to insert into the fixed bayonet when the L-shaped insert rod is inserted into the slot. At the same time, the abutment rod is fixedly engaged in the slot, which facilitates the quick engagement and fixation between the template and the connecting plate, effectively improving the installation efficiency of the template.
[0028] 2. By setting up the ejector spring in conjunction with the compression plate, traction rod, and fixing block, when the traction L-shaped insert rod drives the abutment rod into the slot, the abutment rod pushes the locking disc to align the fixing slot with the fixing block. Then, the ejector spring pushes out the compression plate, causing the compression plate to drive one end of the fixing block into the fixing slot, thereby completing the fixing connection between the locking disc and the connecting disc, which facilitates fixing the abutment rod inside the slot.
[0029] 3. By setting the ejector block and the abutment block to work together, it is easy to drive the safety groove to drive the abutment block and the ejector block to abut against each other while the abutment rod is inserted into the slot. This pushes one end of the ejector block to abut against the outside of the template, thereby improving the alignment between two horizontally adjacent templates and further improving the practicality of the device.

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0037] This application discloses an integrated formwork structure and its construction method.
[0038] Reference Figures 1-3 An integrated formwork structure includes a supporting steel pipe 1. One end of the supporting steel pipe 1 is fixedly connected to a pair of connecting discs 2. The two ends of the side wall of the connecting discs 2 are symmetrically provided with slots 3. An L-shaped rod 4 is inserted into the slot 3. One end of the L-shaped rod 4 is fixedly connected to an abutment rod 5. A locking disc 6 is rotatably connected inside the slot 3. One end of the locking disc 6 is provided with a locking port 7. The other end of the locking disc 6 is provided with a fixing slot 8. A storage groove 9 is provided on the inner side of the slot 3. A fixing block 10 adapted to the fixing slot 8 is installed inside the storage groove 9. One end of the L-shaped rod 4 is fixedly connected to a template 19. An ejector assembly is symmetrically installed on one end of the connecting disc 2.
[0039] In use, the template 19 is first manually pulled to insert the L-shaped rod 4 and the abutment rod 5 into the slot 3, so that the abutment rod 5 is embedded in the locking opening 7 at one end of the locking disc 6. At the same time, the abutment rod 5 abuts against the inner wall of the locking opening 7, and the locking disc 6 rotates around the connecting shaft. The locking disc 6 drives the locking opening 7 to lock the abutment rod 5 into the slot 3. Then, while the locking disc 6 is rotating, it drives the fixing slot 8 to move to the position aligned with the fixing block 10. Then, the spring-loaded characteristic of the ejector component pushes out the fixing block 10, so that one end of the fixing block 10 pushes out of the storage groove 9 and forms a snap-fit with the fixing slot 8. At the same time, the locking disc 6, together with the locking opening 7, fixes the abutment rod 5 in the slot 3. This facilitates the quick snap-fit fixing between the template 19 and the connecting disc 2, effectively improving the installation efficiency of the template 19 and the practicality of the device.
[0040] Reference Figure 2 and Figure 3The ejection assembly includes an operating chamber 11 located inside the connecting plate 2. A compression plate 12 is slidably connected inside the operating chamber 11. A traction rod 13 is fixedly connected to one end of the compression plate 12. An ejection spring 14 is sleeved on one end of the traction rod 13. One end of the ejection spring 14 is fixedly connected to the compression plate 12. One end of the traction rod 13 is fixedly connected to the fixing block 10. The other end of the traction rod 13 passes through the connecting plate 2 and is fixedly connected to a traction handle 15.
[0041] In use, when the guide L-shaped insert rod 4 drives the abutment rod 5 into the slot 3, the abutment rod 5 is inserted into the lock opening 7 and pushes the lock disc 6 to rotate. Then, the lock disc 6 drives the fixed latch 8 to align with the fixed latch block 10. Next, the ejector spring 14 is released from the compression force and produces a rebound deformation. Then, the compression plate 12 is ejected along the length of the traction rod 13. At the same time, the compression plate 12 drives the traction rod 13 to eject the fixed latch block 10, and one end of the fixed latch block 10 is ejected from the inside of the storage groove 9 and forms a snap-fit with the fixed latch 8. This facilitates the fixing of the lock disc 6 and allows the lock disc 6 to cooperate with the slot 3 to fix the abutment rod 5.
[0042] Similarly, when the L-shaped insert rod 4 drives the abutment rod 5 out of the slot 3, firstly, by manually pulling the traction handle 15, the traction handle 15 moves the compression plate 12 along the length of the traction rod 13, causing the compression plate 12 to compress the ejector spring 14 and generate a contraction deformation. At the same time, the traction rod 13 drives one end of the fixing block 10 out of the fixing slot 8 and retracts into the storage groove 9, thereby releasing the locking plate 6. Then, the L-shaped insert rod 4 is manually pulled to drive the abutment rod 5 to push the locking plate 6 to rotate, causing the opening of the lock slot 7 to face upward, so as to guide the abutment rod 5 out of the slot 3.
[0043] Reference Figure 2 and Figure 3 A safety groove 16 is provided at one end of the connecting plate 2, and the traction handle 15 is installed inside the safety groove 16.
[0044] When in use, as the ejector component ejects the fixing block 10 and engages with the fixing slot 8, the traction rod 13 causes the traction handle 15 to retract into the safety groove 16, and the safety groove 16 provides protection for the traction handle 15. This effectively reduces the chance of the traction handle 15 being accidentally touched, causing the abutment rod 5 to disengage from the slot 3, thereby effectively improving the safety of the device.
[0045] Reference Figures 1-3 The connecting plate 2 has a symmetrical ejection groove at one end near the template 19. An ejection block 17 is slidably connected inside the ejection groove. An abutment block 18 is fixedly connected to one end of the locking plate 6. The abutment block 18 abuts against the ejection block 17.
[0046] In use, when the guide L-shaped insert rod 4 drives the abutment rod 5 into the slot 3 and pushes the locking disc 6 to rotate, the locking disc 6 drives the abutment block 18 to rotate, and the abutment block 18 abuts against one end of the ejector block 17. This causes the abutment block 18 to push the ejector block 17 outward along the length of the ejection groove, and one end of the ejector block 17 abuts against the outer side of the template 19. This aligns the two horizontally adjacent templates 19, thereby improving the neatness between the two horizontally adjacent templates 19 and further improving the practicality of the device.
[0047] Reference Figure 1 and Figure 4 The bottom of the template 19 is fixedly connected to a positioning block 20, and the top of the template 19 is provided with a positioning groove 21 that matches the positioning block 20.
[0048] A rubber pad 22 is fixedly connected inside the positioning groove 21, and the positioning block 20 is inserted into the rubber pad 22.
[0049] In use, two vertically adjacent templates 19 are manually pulled together, causing the bottom positioning block 20 of one template 19 to be inserted into the positioning groove 21 at the top of the other template 19. At the same time, the positioning block 20 compresses the rubber pad 22, causing it to stretch and deform, and the rubber pad 22 fills the gap between the positioning block 20 and the positioning groove 21. This effectively improves the connection strength and sealing between two vertically adjacent templates 19.
[0050] Reference Figure 1 and Figure 4 A hollow groove 23 is provided on one side of the template 19, and a reinforcing rib 24 is fixedly connected inside the hollow groove 23.
[0051] In use, the hollowed-out groove 23 effectively reduces the weight of the template 19, making it easier for construction workers to move the template 19. At the same time, the reinforcing ribs 24 strengthen the support and load-bearing capacity of the template 19, thereby effectively improving the practicality of the device.
[0052] A method for integrated formwork construction, comprising the following steps:
[0053] S1: First, the L-shaped insert rod 4 and the abutment rod 5 are inserted into the slot 3 by the traction template 19, and the abutment rod 5 pushes the locking disc 6 to rotate around the joint axis. At the same time, the locking disc 6 drives the locking mouth 7 to lock the abutment rod 5 into the slot 3.
[0054] S2: While completing the above S1 operation, the locking disc 6 drives the fixing slot 8 to align with the storage slot 9, and the ejection spring 14 releases the compression and rebounds to eject the compression plate 12, so that the compression plate 12 drives one end of the fixing block 10 to be inserted into the inside of the fixing slot 8, so as to complete the locking and fixing of the locking disc 6.
[0055] S3: While completing the above S2 operation, the locking disc 6 causes the contact block 18 to come into contact with one end of the ejector block 17, and the contact block 18 pushes the ejector block 17 to move outward along the length of the ejector groove, so that one end of the ejector block 17 comes into contact with the outer side of the template 19.
[0056] S4: After completing the above S3 operation, wait for the concrete to solidify, then manually pull the traction handle 15 to drive the compression plate 12 to squeeze the ejector spring 14 to produce a contraction deformation. At the same time, the traction rod 13 drives one end of the fixed block 10 to disengage from the inside of the fixed slot 8. Then, manually pull the L-shaped insert rod 4 to drive the abutment rod 5 to push the lock plate 6 to make the opening of the lock 7 face upward, and guide the abutment rod 5 to disengage from the inside of the slot 3.
[0057] The implementation principle of the integrated formwork structure and its construction method in this embodiment is as follows: First, the L-shaped insert rod 4 and the abutment rod 5 are inserted into the slot 3 by manually pulling the template 19, so that the abutment rod 5 is embedded in the locking opening 7 at one end of the locking plate 6, and the abutment rod 5 is in contact with the inner wall of the locking opening 7, and the locking plate 6 is rotated around the intersection axis, and the locking plate 6 drives the locking opening 7 to fasten the abutment rod 5 into the slot 3.
[0058] At the same time, the locking disc 6 drives the fixed latch 8 to align with the fixed latch 10. Then, the ejector spring 14 releases the compression force and generates a rebound deformation. Then, the compression plate 12 is ejected along the length of the traction rod 13. At the same time, the compression plate 12 drives the traction rod 13 to eject the fixed latch 10. One end of the fixed latch 10 is ejected from the inside of the storage groove 9 and forms a snap-fit with the fixed latch 8. At the same time, the locking disc 6 cooperates with the locking port 7 to fix the abutment rod 5 in the inside of the slot 3, which facilitates the quick snap-fit fixing between the template 19 and the connecting disc 2.
[0059] Then, when the guide L-shaped insert rod 4 drives the abutment rod 5 into the slot 3 and pushes the locking disc 6 to rotate, the locking disc 6 drives the abutment block 18 to rotate, and the abutment block 18 abuts against one end of the ejector block 17, so that the abutment block 18 pushes the ejector block 17 to move outward along the length of the ejection groove, and one end of the ejector block 17 abuts against the outer side of the template 19, thereby aligning the two horizontally adjacent templates 19.
[0060] Then, when installing two vertically adjacent templates 19, one template 19 is manually pulled to drive the bottom positioning block 20 into the positioning groove 21 at the top of the other template 19. At the same time, the positioning block 20 squeezes the rubber pad 22 to produce an extension deformation, and the rubber pad 22 fills the gap between the positioning block 20 and the positioning groove 21.
[0061] Next, when the L-shaped insert rod 4 drives the abutment rod 5 out of the slot 3, firstly, by manually pulling the traction handle 15, the traction handle 15 moves the compression plate 12 along the length of the traction rod 13, causing the compression plate 12 to compress the ejector spring 14 and generate a contraction deformation. At the same time, the traction rod 13 drives one end of the fixing block 10 out of the fixing slot 8 and retracts into the storage groove 9, thereby releasing the locking plate 6. Then, the L-shaped insert rod 4 is manually pulled to drive the abutment rod 5 to push the locking plate 6 to rotate, and the opening of the lock slot 7 faces upward, so as to guide the abutment rod 5 out of the slot 3.
