Description

Technical Field

[0001] This invention relates to the technical field of building construction, and in particular to a method for constructing explosion-proof formwork. Background Technology

[0002] Conventional exterior wall construction typically involves separate steps for formwork, insulation, and plastering. However, integrated insulation formwork combines these three steps in the factory, thus allowing for the direct integration of insulation and plastering compared to conventional methods.

[0003] However, during construction, the use of concrete blocks in conjunction with tie rods in conventional tie rod construction is prone to displacement during pouring. The formwork is also prone to bulging when poured inside the formwork. The integrated insulation board used in this project, with a thickness of ten centimeters, is even more susceptible to bulging. Furthermore, the sleeve is prone to deformation and corrosion during pouring, leading to leakage and formwork bursting. This makes it difficult to repair the bursting of the integrated insulation board during pouring, severely impacting construction quality. Repairing bursting of the integrated external wall insulation board is difficult, involves multiple steps, and the repair stability is not as strong as that of the poured and bonded material. In addition, traditional tie bolts are not easily recyclable, increasing construction costs.

[0004] Therefore, how to avoid the occurrence of membrane bursting during construction, especially during concrete pouring, reduce the need for later repairs of integrated insulation boards and interior walls, and enable the secondary recycling and reuse of the device are areas that urgently need improvement in current construction methods. Summary of the Invention

[0005] In view of this, the present invention provides a method for constructing explosion-proof formwork rods, which can form a double F-clamp force-bearing structure within the formwork to achieve the effect of explosion-proof formwork.

[0006] The explosion-proof formwork construction method provided by this invention adopts the following technical solution:

[0007] A method for constructing explosion-proof formwork includes the following steps:

[0008] S1: The screw of the explosion-proof mold rod device is passed through the opening of the mold plate and crosses the two mold plates, with both sides of the screw extending out from the outer ends of the two mold plates respectively, and the sleeve on the screw is located inside the two mold plates.

[0009] S2: Move the hooked tie rod of the explosion-proof mold rod towards the inside of the mold, so that it passes through the opening of the mold, and then the hook of the hooked tie rod abuts against the inside of the mold.

[0010] S3: Move the plug of the explosion-proof mold rod along the axial direction of the screw rod and use the fixing component of the explosion-proof mold rod to press the plug tightly against the outside of the template to seal the opening;

[0011] S4: Concrete pouring;

[0012] S5: After the pouring is completed, separate the fixing component from the screw, then remove the plug, pull the screw out from one side of the template, and then cut off the part of the hook that extends out of the template to keep the outer wall of the template flat.

[0013] Optionally, the fixing components include a sliding clip and a nut. In S3, the sliding clip is first slidably fitted onto the screw and pressed against the plug. Then, the nut is threaded onto the screw. Next, the nut is rotated to make the sliding clip push the plug to move and press the sliding clip and the plug against the outside of the template.

[0014] Optionally, the sliding clip has a receiving portion for placing the rod. In S3, the rod is placed in the receiving portion and pressed against the outside of the template. In S5, the rod is removed before removing the fixing assembly.

[0015] Optionally, a mounting part is fixedly provided on the screw, and a driving member is provided on the mounting part. In S2, the driving member slides the hooked pull rod along the axial direction of the screw in the mounting part. In S5, when removing the screw, the driving member is first separated from the hooked pull rod.

[0016] Optionally, a fixing member is provided on the mounting part. The fixing member is used to fix the hook tie rod on the mounting part. In S2, after the hook tie rod is slid to press against the inside of the template, the fixing member fixes the hook tie rod.

[0017] Optionally, the hooked pull rod is provided with multiple broken sections spaced apart along the axial direction of the screw. The broken sections can be broken under force. In S5, the part of the hook that extends out of the template is cut off.

[0018] Optionally, the casing is radially expandable; in S2, after being inserted into the opening, the casing extends radially.

[0019] Optionally, the cannula includes a cannula body and an air bladder. The cannula body is located outside the air bladder, and the air bladder can be expanded by the inflation of air, causing the cannula body to expand radially along the screw.

[0020] Optionally, the plug is provided with a protrusion that is adapted to the diameter of the opening. The plug and the protrusion have an inflation channel. In S3, when the plug is pressed against the outside of the template, the protrusion extends into the opening and the inflation channel connects with the airbag.

[0021] In summary, the present invention includes at least one of the following beneficial technical effects: This construction method enables the explosion-proof membrane rods to form a double F-clamp force within the template, preventing the integrated external wall insulation board from bursting. After the integrated external wall insulation board bursts, it is not easy to repair. This device controls this beforehand, avoiding such quality problems. Furthermore, the rods can be removed and reused, which is environmentally friendly and energy-saving. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0027] This invention discloses a method for constructing explosion-proof formwork.

[0028] Reference Figure 1 , Figure 2 , Figure 3 A method for constructing explosion-proof formwork includes the following construction steps:

[0029] S1: The screw 10 of the explosion-proof mold rod device passes through the opening 2 of the template and crosses the two templates, so that both sides of the screw 10 extend from the outer ends of the two templates respectively, and the sleeve 11 on the screw 10 is located inside the two templates.

[0030] S2: Move the hooked tie rod 1 of the explosion-proof mold rod towards the inside of the mold, so that it passes through the opening 2 of the mold, and then the hook of the hooked tie rod 1 abuts against the inside of the mold.

[0031] S3: Move the plug 9 of the explosion-proof mold rod along the axial direction of the screw 10 and use the fixing component of the explosion-proof mold rod to press the plug 9 against the outside of the template to seal the opening 2;

[0032] S4: Concrete pouring;

[0033] S5: After the pouring is completed, separate the fixing component from the screw 10, then remove the plug 9, pull the screw 10 out from one side of the template, and then cut off the part of the hook that extends out of the template to keep the outer wall of the template flat.

[0034] This construction method creates a double-F snap-fit ​​structure within the formwork for the explosion-proof membrane members, preventing the integrated exterior wall insulation board from bursting. Since bursting of the integrated exterior wall insulation board is difficult to repair, this device allows for pre-control, avoiding such quality problems. Furthermore, the members can be removed for reuse, making it environmentally friendly and energy-saving.

[0035] In this embodiment, the explosion-proof template rod device includes a screw rod 10, a hooked pull rod 1, a sleeve 11, and a fixing assembly. The screw rod 10 passes through the opening 2 of the template and traverses both sides of the template. The hooked pull rod 1 is disposed on the screw rod 10 and has a hook portion for pressing against the inner side of the template. The sleeve 11 is coaxially sleeved on the outer side of the screw rod 10 and is located on the inner side of the two templates. The screw rod 10 can slide axially relative to the sleeve 11. The fixing assembly is disposed on the screw rod 10 and is used to press against the outer side of the template.

[0036] In this embodiment, the explosion-proof formwork construction method is used for supporting and fixing integrated thermal insulation formwork. The material involves three processes: formwork, insulation, and plastering; using this material reduces these three processes to a single step. The integrated thermal insulation formwork serves as the exterior wall formwork, and is cast together with concrete using plastic studs, forming an integrated construction process encompassing formwork, insulation, and plastering.

[0037] In this embodiment, the fixing component includes a sliding clip 3 and a nut 6. The sliding clip 3 is slidably fitted onto the screw rod 10, and the nut 6 is threaded onto the screw rod 10. The nut 6 is used to restrict the sliding clip 3 from moving outward. In S3, the sliding clip 3 is first slidably fitted onto the screw rod 10 and pressed against the plug 9. Then, the nut 6 is threaded onto the screw rod 10. Next, the nut 6 is rotated to make the sliding clip 3 push the plug 9 to move and press the sliding clip 3 and the plug 9 against the outside of the template. In S5, the nut 6 is first removed, and then the sliding clip 3 is removed to complete the removal of the fixing component.

[0038] In this embodiment, a plug 9 is provided on the screw 10. There is a gap between the screw 10 and the opening 2. The plug 9 is used to seal the gap. The sliding clip 3 applies an inward preload to the plug 9 in cooperation with the nut 6.

[0039] In this embodiment, the sliding clip 3 has a receiving portion 8 for placing a rod. When the rod is located in the receiving portion 8, it can be pressed against the outside of the template. In this embodiment, the rod is a steel pipe. The steel pipe is placed in the receiving portion 8 so that it is pressed against the outside of the template, thereby improving the support effect of the template. In S3, the rod is placed in the receiving portion 8 so that it is pressed against the outside of the template; in S5, the rod is removed before removing the fixing component.

[0040] In this embodiment, a mounting portion is provided on the screw 10, and a driving member 4 is provided on the mounting portion. The hook pull rod 1 is slidably mounted on the mounting portion via the driving member 4. In this embodiment, the driving member 4 is a bolt. A sliding hole is provided on the mounting portion along the axial direction of the screw 10, and the bolt restricts the hook pull rod 1 within the sliding hole. Sliding blocks are provided on both sides of the hook pull rod 1 laterally, and a sliding groove is provided on the mounting portion along the axial direction of the screw 10. The sliding blocks are slidably fitted within the sliding groove, and the operator slides the hook pull rod 1 via the driving member 4. In S2, the driving member 4 slidably mounts the hook pull rod 1 on the mounting portion along the axial direction of the screw 10. In S5, when removing the screw 10, the driving member 4 is first separated from the hook pull rod 1.

[0041] The hook is rotatably mounted on the hooked pull rod 1 via a rotating part. A torsion spring is provided at the rotating part and the hooked pull rod 1. The torsion spring is used to apply elastic force to the hook, so that the hook and the hooked pull rod 1 form an angle, so that it presses against the inner side of the template.

[0042] In this embodiment, a fixing member 5 is provided on the mounting part, which is used to fix the hook tie rod 1 to the mounting part. In this embodiment, the fixing member 5 is a bolt, and the mounting part is used to fix the hook tie rod 1 in the sliding hole, restricting its axial sliding. In S2, after the hook tie rod 1 is slid to abut against the inner side of the template, the fixing member 5 fixes the hook tie rod 1. The fixing member 5 and the driving member 4 fix the hook tie rod 1 to a plane at two points, thereby completing the fixing of the hook tie rod 1 and making the support of the hook tie rod 1 for the template more stable.

[0043] In S5, when separating the hook rod 1 from the screw 10, the fixing part 5 and the driving part 4 are removed first, thereby completing the separation of the two.

[0044] The hooked pull rod 1 can be detached from the mounting part and fixed by the driving component 4 and the fixing component 5, which not only facilitates later replacement, but also provides fixed support for the hooked pull rod 1.

[0045] In this embodiment, the hook-type tie rod 1 has multiple broken sections spaced apart along the axial direction of the screw 10. These broken sections can be broken under force. In this embodiment, the broken sections are grooves formed on the hook-type tie rod 1, and their thickness is thinner than the unformed sections. In step S5, after removing the screw 10 and the sliding clip 3, nut 6, and plug 9 provided on the screw 10, the hook-type tie rod 1 extending outside the template is broken through the broken sections, completing the overall disassembly. When supporting the template again, only the hook-type tie rod 1 needs to be replaced.

[0046] In this embodiment, the sleeve 11 is radially expandable. Specifically, the sleeve 11 includes a sleeve body 111 and an air bladder 112. The sleeve body 111 is disposed outside the air bladder 112. The air bladder 112 can be expanded by inflation, causing the sleeve body 111 to expand radially along the screw 10.

[0047] In this embodiment, the sleeve body 111 includes a fixed part and a sliding part, which are circumferentially closed to form a ring. The sliding part is slidably fitted onto the fixed part. In S2, after being inserted into the opening 2, the air bladder 112 is inflated, and the sliding part slides out from the fixed part, thereby increasing the overall size of the sleeve body 111.

[0048] In this embodiment, the diameter of the opening 2 of the template is larger than the diameter of the screw 10.

[0049] In this embodiment, the plug 9 is provided with a protrusion 7, which is adapted to the diameter of the opening 2. The plug 9 and the protrusion 7 have an inflation channel. When the plug 9 is pressed against the outside of the template, the protrusion 7 extends into the opening 2, and the inflation channel communicates with the airbag part 112. The inflation channel located in the plug 9 has a sealing element, which is used to seal the inflation channel and effectively prevent gas from escaping from the inflation channel at the plug 9. The airbag part 112 has an inflation port, which is made of elastic material. The inflation channel located in the protrusion 7 has an inflation needle. In S3, the inflation needle is inserted into the inflation port for inflation. After the two are separated, the inflation port automatically closes.

[0050] In this embodiment, the protrusion 7 seals the opening, effectively preventing concrete from blocking the opening when the formwork is removed, which would otherwise require a second removal of the formwork at the opening. This achieves both inflation of the airbag 112 and ensures the flatness of the concrete pouring.

[0051] During inflation, the outer surface of the sleeve body 111 abuts against the hooked rod 1, indicating that the inflation is complete. When inflation is released, the sleeve body 111 provides auxiliary support to the bottom of the hooked rod 1, improving the overall support effect.

[0052] This invention employs a double-locking mechanism between the integrated insulation and the inner and outer sides of the formwork, ensuring that the integrated insulation is stressed on both sides and cannot be moved to either side. Compared to traditional integrated insulation construction methods, this results in better stability, lower post-construction repair costs, and wider applicability. It significantly reduces the need for subsequent interior and exterior wall repairs, saving construction time. The construction is simple, energy-efficient, and environmentally friendly, while also shortening the post-construction repair period and reducing subsequent exterior wall work.

[0053] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
