Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a doorway reinforcement formwork device. Background Technology

[0002] Many buildings now employ slipform construction technology, which improves construction efficiency. For buildings with doors and windows, slipform construction involves installing doorway formwork between the slipform side panels, pouring concrete, and then removing the doorway formwork once the concrete has hardened and the slipform has risen above it. Currently, common doorway formwork uses welded steel plates to form a rectangular frame structure. This method requires on-site welding, which is inconvenient, and the large size makes it difficult to transport after use. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a door opening reinforcement formwork device that is modularly assembled, easy to disassemble and disassemble, and easy to transport.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A doorway reinforcement formwork support device includes a formwork frame and a pressure-bearing bracket disposed within the formwork frame. The formwork frame has a cuboid structure and includes a lower formwork, an upper formwork, and two side formworks. The pressure-bearing bracket has a rectangular structure and includes a lower reinforcing beam fixed to the upper side of the lower formwork, an upper reinforcing beam fixed to the lower side of the upper formwork, and a side reinforcing beam fixed to the side of the side formwork. The lower end of the side reinforcing beam abuts against the upper side of the end of the lower reinforcing beam, and the upper end of the side reinforcing beam abuts against the lower side of the end of the upper reinforcing beam. A connecting component is provided between any two adjacent formworks within the formwork frame, and the two adjacent formworks are detachably connected through the connecting component.

[0006] By adopting the above technical solution: the template frame is used to form the doorway space, the pressure-bearing bracket inside the template frame is used to enhance the overall compressive strength, and the two ends of the side reinforcing beam inside the template frame are supported and pressure-bearing through abutment. Adjacent templates can be directly detached and connected. This makes the disassembly and installation of the upper template, lower template, and side template more convenient. They can be disassembled and transported during handling, and can be quickly assembled and used when moved to the construction site.

[0007] Preferably, the upper reinforcing beam, lower reinforcing beam, and side reinforcing beam are all made of square tubing. The upper reinforcing beam is welded to the upper template, the lower reinforcing beam is welded to the lower template, and the side reinforcing beams are welded to the side templates. Square tubing structures have high strength, are readily available, have low cost, and are easy to process.

[0008] Preferably, the pressure-bearing support is positioned at the center of the template frame. Both ends of the side reinforcing beam are fixed with limiting members protruding from the ends of the side reinforcing beams, forming a limiting groove between the two limiting members at the same end of the side reinforcing beam. The two ends of the upper reinforcing beam are engaged in the limiting grooves at the upper ends of the side reinforcing beams, and the two ends of the lower reinforcing beam are engaged in the limiting grooves at the lower ends of the side reinforcing beams. Positioning the pressure-bearing support in the middle position makes the template frame more balanced and stable under pressure. The limiting grooves, engaged with the lower and upper reinforcing beams, facilitate positioning during assembly and bear the lateral pressure, preventing misalignment between templates.

[0009] Preferably, the connecting assembly includes two vertically distributed connecting sleeves and a connecting rod. The two connecting sleeves are respectively fixed to two adjacent templates. The connecting rod is L-shaped, and its two ends are inserted into the two connecting sleeves to form a plug-in connection. The sides of the connecting sleeves are provided with fasteners for locking the connecting rods. After one end of the connecting rod is inserted into the connecting sleeve and fixed by the fasteners, the other set of connecting sleeves can be directly fitted into the other end of the connecting rod to achieve a vertical connection.

[0010] Preferably, the connection components between any two adjacent templates are configured as two sets. Setting two sets of connection components further improves connection stability.

[0011] Preferably, a reinforcing bracket is provided within the pressure-bearing support, located between the two side reinforcing beams, with both ends of the reinforcing bracket detachably connected to the side reinforcing beams. This reinforcing bracket further increases the compressive strength between the side formwork panels.

[0012] Preferably, the reinforcing bracket has an I-shaped structure, which is formed by welding square tubes to form an I-beam. Limiting blocks are fixed on both sides of the end of the reinforcing bracket, and a slot is formed between the two limiting blocks. The slot is engaged with the side reinforcing beam. The limiting block is provided with a first connecting through hole, and the side reinforcing beam is provided with a second connecting through hole that matches the first connecting through hole. The first connecting through hole and the second connecting through hole are fastened together by bolts and nuts.

[0013] Preferably, the system also includes embedded components for positioning the formwork frame. These components include an embedded base and a threaded sleeve fixed to the embedded base, with a threaded rod inside the threaded sleeve. The lower formwork has several connecting holes, through which the threaded rod passes and is secured by nuts. During slipform construction, the embedded parts are embedded in the concrete. When installing the formwork frame, the threaded rod is inserted through the connecting holes, with its lower end connected to the threaded sleeve. Finally, the formwork frame is connected and positioned to the threaded rod using nuts. If the formwork frame needs to be removed, the nuts are loosened, the threaded rod is removed, and the entire formwork support device can be pulled out using equipment.

[0014] Therefore, this utility model has the advantages of modular assembly, convenient disassembly and assembly, and convenient transportation. Attached Figure Description

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.

[0024] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.

[0025] like Figures 1-7The illustrated doorway reinforcement formwork device includes a formwork frame 10 and a pressure-bearing support 20 disposed within the formwork frame 10. The formwork frame 10 has a cuboid structure and includes a lower formwork 11, an upper formwork 12, and two side formworks 13. The pressure-bearing support 20 has a rectangular structure and includes a lower reinforcing beam 21 fixed to the upper side of the lower formwork 11, an upper reinforcing beam 22 fixed to the lower side of the upper formwork 12, and a side reinforcing beam 23 fixed to the side of the side formwork 13. The lower end of the side reinforcing beam 23 abuts against the upper side of the end of the lower reinforcing beam 21, and the upper end of the side reinforcing beam 23 abuts against the lower side of the end of the upper reinforcing beam 22. A connecting component 30 is provided between any two adjacent formworks within the formwork frame 10, and the two adjacent formworks are detachably connected by the connecting component 30.

[0026] The upper reinforcing beam 22, lower reinforcing beam 21, and side reinforcing beam 23 are all made of square tubing. The upper reinforcing beam 22 is welded to the upper formwork 12, the lower reinforcing beam 21 is welded to the lower formwork 11, and the side reinforcing beam 23 is welded to the side formwork 13. The lower formwork 11, upper formwork 12, and two side formworks 13 can be made of aluminum alloy plates, steel plates, iron plates, or other metal sheets, depending on the actual pressure conditions during use.

[0027] The pressure-bearing support 20 is located at the center of the template frame 10. Both ends of the side reinforcing beam 23 are fixed with limiting members 230 protruding from the ends of the side reinforcing beam 23. A limiting groove 231 is formed between the two limiting members 230 at the same end of the side reinforcing beam 23. The two ends of the upper reinforcing beam 22 are inserted into the limiting groove 231 at the upper end of the side reinforcing beam 23, and the two ends of the lower reinforcing beam 21 are inserted into the limiting groove 231 at the lower end of the side reinforcing beam 23. In some embodiments, the limiting member 230 is also made of square tubing, i.e., the square tubing is cut to a preset length and directly welded to the two ends of the side reinforcing beam 23. To further increase the connection stability between the limiting member and the side reinforcing beam, the limiting member and the side reinforcing beam are welded together and then secured with bolts (or screws) and nuts.

[0028] like Figure 4 and Figure 5 As shown, the connecting assembly 30 includes two vertically distributed connecting sleeves 31 and a connecting rod 32. The two connecting sleeves 31 are respectively fixed on two adjacent templates. The connecting rod 32 is L-shaped, and both ends of the connecting rod 32 are inserted into the two connecting sleeves 31 to form a plug-in connection. The side of the connecting sleeve 31 is provided with fasteners 33 for locking the connecting rod 32. In some embodiments, the connecting assembly 30 between any two adjacent templates is configured as two sets. The connecting sleeves are also made of square tubes, that is, square tubes are cut to the required length and then welded onto the template. In order to further improve the ease of assembly, the cross-section of the connecting rod adopts a rectangular structure corresponding to the inner hole of the connecting sleeve, so that after one end of the connecting rod is inserted into the connecting sleeve, the direction of the other end of the connecting rod remains stable.

[0029] like Figure 6 and Figure 7 As shown, a reinforcing bracket 40 is provided inside the pressure-bearing bracket 20 between the two side reinforcing beams 23. Both ends of the reinforcing bracket 40 are detachably connected to the side reinforcing beams 23. The reinforcing bracket 40 has an I-shaped structure and is formed by welding square tubes to form an I-beam frame. Limiting blocks 41 are fixed on both sides of the end of the reinforcing bracket 40, and a slot 410 is formed between the two limiting blocks 41. The slot 410 is engaged with the side reinforcing beams 23. The limiting blocks 41 are provided with a first connecting through hole 411, and the side reinforcing beams 23 are provided with a second connecting through hole 232 that matches the first connecting through hole 411. The first connecting through hole 411 and the second connecting through hole 232 are fastened together by bolts 42 and nuts 43. In some embodiments, the limiting block is also made of square tube, that is, the square tube is cut into a preset length and then welded (or fixed with bolts and nuts) to the end of the reinforcing bracket 40, and finally connected to the side reinforcing beam by bolts 42 and nuts 43. Each side reinforcing beam is provided with at least two first connecting through holes 411, one of which is a round hole and the other is a vertical slot hole, which reduces the connection accuracy requirement and improves the convenience of installation of the reinforcing bracket.

[0030] like Figure 1 and Figure 4 As shown, it also includes a pre-embedded component 50 for positioning the template frame 10. The pre-embedded component 50 includes a pre-embedded base 51 and a threaded sleeve 52 fixed on the pre-embedded base 51. A threaded rod 53 is provided inside the threaded sleeve 52. The lower template 11 is provided with several connecting holes 110. The threaded rod 53 passes through the connecting holes and is fastened by a nut. The pre-embedded component facilitates the positioning of the formwork support device. When the formwork support device needs to be removed after use, the nuts and threaded rods are first removed, and then the whole device is pulled out from the doorway to one side by a traction device.

[0031] like Figure 8 As shown, the long sides of the upper template 12 and the lower template 11 are both arc-shaped, making them suitable for slip-form construction of cylindrical structures.

[0032] Referring to the accompanying drawings, the principle of this utility model is as follows: Figure 1As shown, the lower template is connected and positioned with the embedded parts; the template frame is used to construct the doorway space, and the pressure-bearing brackets inside the template frame are used to enhance the overall compressive strength. Both ends of the side reinforcing beams inside the template frame are supported and pressure-bearing through abutment. The side reinforcing beams are further reinforced and supported by reinforcing brackets, resulting in stable overall support. Based on this structure, the formwork for any rectangular doorway can be supported simply by adjusting the size; adjacent templates can be directly detached and connected. After disassembly, a formwork device consists of four templates (with connecting sleeves and reinforcing beams), reinforcing brackets, and several connecting rods. With fewer parts and a high degree of standardization, installation, disassembly, and transportation are more convenient; a large number of components are made of square tubing, such as the upper reinforcing beam, lower reinforcing beam, side reinforcing beam, connecting sleeve, limiting parts, and limiting blocks, all of which can be made by cutting square tubing, making the materials simple and the cost low.

[0033] This makes the disassembly and installation of the upper formwork, lower formwork, and side formwork more convenient. They can be disassembled and transported during transport, and can be quickly assembled and used when moved to the construction site.

[0034] In the description of this utility model, it should be understood that the directions or positional relationships indicated by up, down, left, right, inner end, outer end, one end, and the other end are based on the orientation or positional relationships shown in the accompanying drawings. They are only for the purpose of more clearly describing the technical solution of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as a limitation of this utility model.

[0035] Although specific embodiments of the present invention are described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of the present invention. Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present invention.
