Description

Technical Field

[0001] This invention relates to the field of concrete formwork technology, specifically to a quick-release formwork and its construction method. Background Technology

[0002] Concrete formwork is widely used in engineering construction due to its advantages such as convenient construction, reusability, and fast casting speed. However, simple single-slab concrete formwork has its disadvantages after long-term use. For example, when large-area adhesion occurs, large equipment is required for pulling and ripping. Disassembly is not only troublesome, time-consuming and labor-intensive, but also easily damages the concrete formwork, making it unusable for reuse. Moreover, most of the disassembly methods for concrete formwork nowadays involve pulling and ripping or prying that damages the outside, which cannot ensure the integrity of the formwork or speed up the disassembly process. To address the above problems, a quick-disassembly formwork and construction method is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a quick-release template and construction method to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a quick-release template, comprising a multi-plate splicing template, wherein a plurality of traction brackets are mounted on the top of the multi-plate splicing template, and traction demolding components that cooperate with the multi-plate splicing template are mounted on the traction brackets, and extrusion components that are linked to the traction demolding components are mounted on both sides of the traction demolding components, and auxiliary reinforcement components are mounted on the multi-plate splicing template.

[0005] Preferably, the multi-plate splicing template includes an outer ring bracket and a splicing plate bracket. A support template is fixedly connected to the bottom of the outer ring bracket. The support template has multiple filling slots. A reinforcing beam is fixedly connected between two adjacent filling slots. The reinforcing beam is fixedly connected to the outer ring bracket. An annular leak-proof baffle is integrally formed at the lower end of the inner sidewall of the filling slot. Three splicing plates are sleeved inside the filling slot. Matching baffles are integrally formed at the positions of the three splicing plates and the annular leak-proof baffle. Two splicing plates at the ends are fixedly connected to the splicing plate bracket. Extension columns are fixedly connected at the four corners of the upper end of the splicing plate in the middle. Limit caps are integrally formed at the top of the extension columns. The extension columns penetrate the splicing plate bracket and are limited and sleeved on the splicing plate bracket by the limit caps. Four upwardly extending limit columns are integrally formed in a square on the splicing plate bracket.

[0006] Preferably, the traction bracket includes a U-shaped bracket, the lower ends of which are fixedly connected to the outer ring bracket on both sides. The outer edge of the U-shaped bracket is square and integrally formed with four limiting sleeves, which are respectively sleeved with four limiting posts.

[0007] Preferably, the pull-out assembly includes two lever pull arms, each with a shaft fixedly connected to its opposite end. The lever pull arms are rotatably mounted on a U-shaped bracket via the shafts. A U-shaped pull arm is rotatably mounted on each lever pull arm. Connecting shafts are bent at both ends of the lower side of each U-shaped pull arm. Connecting blocks are rotatably connected to each of the two connecting shafts. Four connecting blocks are fixedly connected to the splicing plate bracket. Transmission gears are fixedly connected to both sides of the two shafts located on the U-shaped bracket. The transmission gears on the two shafts mesh with each other.

[0008] Preferably, the extrusion assembly includes an extrusion arm, the lower side of which is rotatably connected to a connecting shaft. The upper end of the extrusion arm is integrally formed with a relief groove, and an extrusion column is sleeved in the relief groove. A top column is fixedly connected to the outer end of the extrusion column, and the top column is fixedly connected to the shaft.

[0009] Preferably, the auxiliary reinforcement component includes four mounting sleeves, which are respectively fixedly connected to the four corners of the outer ring bracket. The upper end of each mounting sleeve is screwed with a compression stud, and two opposing horizontal mounting sleeves are fitted with reinforcement beams that cooperate with the compression studs.

[0010] A quick-release formwork construction method, S1. During the disassembly operation, the worker loosens the clamping studs and pulls out the reinforcing beam; S2. The worker manually turns the lever pull arm, and the lever pull arm rotates along the rotating installation point with the U-shaped bracket, causing the U-shaped pull arm and connecting block to rise. S3. The connecting block pulls the splicing plate bracket to rise. During the rise of the splicing plate bracket, the splicing plates at both ends of the splicing plate bracket are first pulled up to demold. After the splicing plate bracket is squeezed together with the limit cap, the middle splicing plate is pulled up to demold through the extension column. S4. The worker inserts the reinforcing beam into the installation sleeve on one side, and uses the installation sleeve and the concrete surface as fulcrums to pry it up with a lever, pulling the outer ring bracket to lift the support template and demold it, thus completing the demolding operation.

[0011] Preferably, S2 specifically means that when the splicing plate is too large and the bonding area with the concrete is too large, and manual operation cannot lift the lever arm, a jack or large mechanical equipment can be used to pry it.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention divides the multi-panel splicing formwork into multiple independent individuals, reducing the area of ​​each individual and avoiding the problem of difficult disassembly due to the large area of ​​the whole being bonded to the concrete. Furthermore, it utilizes a pull-out demolding component to pull and demold the splicing panels, using the lever principle to save effort. At the same time, during disassembly, it avoids pulling and tugging on the edges and corners, protecting the formwork and preventing the disassembly force from being applied directly to the edges and corners, which could cause the formwork to deform and become unusable. In addition, disassembly is more labor-saving and efficient.

[0013] Example 2: When using the pull-out demolding assembly, the lever pull arm is turned, and the lever pull arm rotates along the rotating mounting point with the U-shaped bracket, causing the U-shaped pull arm and connecting block to rise. At the same time, the opposing lever pull arms are linked by the meshing transmission gears. The lever pull arm can be turned on one side to demold the splicing plate, or both lever pull arms can be turned on simultaneously to demold the splicing plate, thus achieving the function of convenient and labor-saving demolding.

[0014] Example 3: When this quick-release template is in use, the extrusion arm and the top column are on the same straight line. Using the connecting shaft and connecting block, the splicing plate support can be extruded, and the multi-plate splicing template assembled together can be initially extruded, which facilitates the secondary reinforcement of the subsequent auxiliary reinforcement components.

[0015] Example 4: This quick-release formwork construction method is used in conjunction with one of the quick-release formworks mentioned above, making disassembly more stable, convenient and quick, accelerating construction efficiency, and avoiding the problem of formwork damage and inability to be reused.

Detailed Implementation

[0022] 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. Example 1:

[0023] Please see Figure 1-5 The present invention provides a technical solution: a quick-release template, including a multi-plate splicing template 1, a plurality of traction brackets 2 are mounted on the top of the multi-plate splicing template 1, a traction demolding component 3 that cooperates with the multi-plate splicing template 1 is mounted on the traction brackets 2, and a pressing component 4 that is linked with the traction demolding component 3 is mounted on both sides of the traction demolding component 3, and an auxiliary reinforcement component 5 is mounted on the multi-plate splicing template 1.

[0024] The multi-panel splicing formwork 1 of this invention is composed of multiple spliced ​​panels, dividing a single panel into multiple independent individuals. This avoids the problem of difficulty in disassembly caused by an excessively large area of ​​the single panel adhering to the concrete. Furthermore, during disassembly, the pull-out demolding assembly 3, using the pull-out bracket 2 as a fulcrum, leverages the lever principle to pull apart the multi-panel splicing formwork 1 installed with it for demolding. Simultaneously, the reinforcing beam 53 on the auxiliary reinforcement assembly 5 cooperates with the mounting sleeve 51 to leverage and pry the outer ring bracket 101, supporting the formwork 103 for demolding. Therefore, compared to the current method where the single panel area is too large, this invention significantly improves demolding efficiency. When the formwork is bonded to the concrete, it requires large machinery to pull and yank it for disassembly. In contrast, this invention divides the multi-panel splicing template 1 into multiple independent units, reducing the area of ​​each individual unit. This avoids the problem of disassembly being troublesome due to the large area bonded to the concrete. Furthermore, the pull-and-release assembly 3 is used to pull and release the splicing panels 107, which is more labor-saving due to the lever principle. At the same time, during disassembly, the corners are not pulled and yanked, protecting the template and preventing the disassembly force from being applied directly to the corners, which could cause the template to deform and become unusable. This makes disassembly more labor-saving and efficient.

[0025] Specifically, the multi-plate splicing template 1 includes an outer ring support 101 and a splicing plate support 102. A support template 103 is fixedly connected to the bottom of the outer ring support 101. The support template 103 has multiple filling grooves 104. A reinforcing beam 105 is fixedly connected between two adjacent filling grooves 104. The reinforcing beam 105 is fixedly connected to the outer ring support 101. An annular leak-proof baffle 106 is integrally formed on the lower end of the inner sidewall of the filling groove 104. Three splicing plates 107 are sleeved inside the filling groove 104, and the three splicing plates 107 are connected to the annular leak-proof baffle. A matching baffle 108 is integrally formed at the opposite position of 106. The two splicing plates 107 at the ends are fixedly connected to the splicing plate bracket 102. An extension post 111 is fixedly connected to the upper four corners of the splicing plate 107 in the middle. The length of the extension post 111 is greater than the thickness of the splicing plate bracket 102. The top of the extension post 111 is integrally formed with a limit cap 109. The extension post 111 passes through the splicing plate bracket 102 and is limited and sleeved on the splicing plate bracket 102 by the limit cap 109. The splicing plate bracket 102 has four square, integrally formed, upwardly extending limit posts 110.

[0026] When the multi-plate splicing formwork 1 is in use, three splicing plates 107 are used. The two splicing plates 107 at the ends are fixedly connected to the splicing plate bracket 102. The splicing plate 107 in the middle is installed together with the splicing plate bracket 102 through the extension column 111 and the limiting cap 109. When the splicing plate bracket 102 is pulled up by the pulling demolding component 3, the splicing plates 107 at both ends of the splicing plate bracket 102 will be pulled up and demolded first. When the limiting cap 109 is squeezed together with the splicing plate bracket 102, the splicing plate 107 in the middle will be pulled up and demolded. This realizes the function of demolding the splicing plates 107 one by one, avoiding the problem of demolding difficulties when the overall area of ​​the multi-plate splicing formwork 1 is too large and a large area is adhered to the concrete.

[0027] Specifically, the traction bracket 2 includes a U-shaped bracket 21, the lower ends of which are fixedly connected to the outer ring bracket 101 on both sides. The outer edge of the U-shaped bracket 21 is integrally formed into a square shape with four limiting sleeves 22, which are respectively sleeved with four limiting posts 110.

[0028] Specifically, the auxiliary reinforcement component 5 includes four mounting sleeves 51, which are fixedly connected to the four corners of the outer ring bracket 101. The upper end of each mounting sleeve 51 is screwed with a compression stud 52, and the lower end of the compression stud 52 extends into the mounting sleeve 51. Two horizontally opposite mounting sleeves 51 are fitted with a reinforcement beam 53 that is compressed against the compression stud 52. The reinforcement beam 53 is compressed together with the splicing plate bracket 102.

[0029] When this quick-release formwork is used for grouting, the reinforcing beam 53 limits and squeezes the splice plate support 102 to avoid excessive pressure during grouting, which could cause the splice plate 107 to be impacted and squeezed open. At the same time, when this quick-release formwork is disassembled, the reinforcing beam 53 cooperates with an installation sleeve 51 to pry the outer ring support 101 using the lever principle, so that it supports the formwork 103 to be demolded. Example 2:

[0030] A quick-release template, with other features the same as in Embodiment 1, except that: Figure 1-2 and Figure 6 As shown: Specifically, the pull-out assembly 3 includes two lever pull arms 31, each with a shaft 32 fixedly connected to its opposite end. The lever pull arms 31 are rotatably mounted on the U-shaped bracket 21 via the shafts 32. A U-shaped pull arm 33 is rotatably mounted on the lever pull arms 31. Both lower ends of the U-shaped pull arm 33 have bent connecting shafts 34. Connecting blocks 35 are rotatably connected to both connecting shafts 34. All four connecting blocks 35 are fixedly connected to the splicing plate bracket 102. Transmission gears 36 are fixedly connected to both sides of the two shafts 32 on the U-shaped bracket 21. The transmission gears 36 on the two shafts 32 mesh with each other.

[0031] When in use, the pull-out demolding assembly 3 is turned by lever pull arm 31, which rotates along the rotatable mounting point with U-shaped bracket 21, causing U-shaped pull arm 33 and connecting block 35 to rise. At the same time, the opposing lever pull arms 31 are linked by the meshing transmission gear 36. The lever pull arm 31 can be turned on one side to demold the splicing plate 107, or the lever pull arms 31 on both sides can be turned on simultaneously to demold the splicing plate 107, thus realizing the function of convenient and labor-saving demolding. Example 3:

[0032] A quick-release template, with other features the same as in Embodiment 2, except that: Figure 1-2 and Figure 7 As shown: Specifically, the extrusion assembly 4 includes an extrusion arm 41, the lower side of which is rotatably connected to a connecting shaft 34. The upper end of the extrusion arm 41 is integrally formed with a relief groove 42, and an extrusion column 43 is sleeved in the relief groove 42. The outer end of the extrusion column 43 is fixedly connected to a top column 44, which is fixedly connected to the shaft 32.

[0033] When this quick-release template is in use, the compression arm 41 and the top column 44 are on the same straight line. Using the connecting shaft 34 and the connecting block 35, the splicing plate bracket 102 can be compressed, and the multi-plate splicing template 1 assembled together can be initially compressed, which facilitates the secondary reinforcement of the auxiliary reinforcement component 5.

[0034] During the demolding process, the extrusion arm 41 and the top column 44 form an angle, and the extrusion column 43 can slide in the relief groove 42 so that it will not obstruct the rise of the splicing plate bracket 102. Example 4:

[0035] A quick-release formwork construction method, S1. During the disassembly operation, the worker loosens the clamping stud 52 and pulls out the reinforcing beam 53; S2. The worker manually turns the lever pull arm 31, and the lever pull arm 31 rotates along the rotational installation point with the U-shaped bracket 21, causing the U-shaped pull arm 33 and the connecting block 35 to rise. S3. During the upward movement of the connecting block 35, the splicing plate bracket 102 will be pulled up. During the upward movement of the splicing plate bracket 102, the splicing plates 107 at both ends of the splicing plate bracket 102 will be pulled up and demolded. After the splicing plate bracket 102 is squeezed together with the limit cap 109, the middle splicing plate 107 will be pulled up and demolded through the extension column 111. S4. The worker inserts the reinforcing beam 53 into the installation sleeve 51 on one side, and uses the reinforcing beam 53 and the concrete surface as fulcrums to pry it with a lever, pull the outer ring bracket 101, and pry up the support template 103 to demold, thus completing the demolding operation.

[0036] Specifically, S2 means that when the splicing plate 107 is too large and the bonding area with the concrete is too large, and manual operation cannot lift the lever arm 31, a jack or large mechanical equipment can be used to pry it.

[0037] This quick-release formwork construction method is used in conjunction with one of the aforementioned quick-release formworks to make disassembly more convenient and faster, thus accelerating construction efficiency and avoiding the problem of formwork damage and inability to be reused.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
