Description

Technical Field

[0001] This utility model belongs to the technical field of formwork construction for window opening lintels and coping in building construction, specifically an integrated formwork device for upper and lower lintels of ultra-wide window openings. Background Technology

[0002] In general, when the width of door and window openings in a building is less than 1m, the lintels and capping beams can be precast concrete. This involves casting the concrete off-site using formwork, and then manually transporting it to the construction site for installation once the concrete has reached a certain strength. However, these beams cannot be too large; their dimensions must be controlled within 1m in length, 0.2m in width, and 0.1m in height, otherwise they cannot be moved manually. Therefore, when the dimensions are too large, the beams must be cast in place. This method requires first casting the capping beam below the window opening, and then, after the capping beam has hardened, constructing the remaining wall. After the wall is completed, formwork is re-established, and the lintel above the window opening is cast. Only after the lintel has hardened can the masonry work above it be completed. This conventional method requires significant labor and time costs, has low work efficiency, and can easily affect the progress of the entire project.

[0003] Therefore, how to effectively solve the problem of the high labor and time costs, low work efficiency, and potential impact on the progress of the entire project when the door and window openings are too large, requiring sequential construction of lintels and capping beams, is an urgent technical issue that needs to be addressed. Utility Model Content

[0004] To address the shortcomings in the aforementioned background technology, this utility model proposes an integrated formwork support device for ultra-wide window opening upper and lower lintels. This solves the problem that when the size of the door and window openings is too large, the construction of the lintels and capping beams in sequence requires a lot of manpower and time, resulting in low work efficiency and easily affecting the progress of the entire project.

[0005] The technical solution of this application is as follows:

[0006] An integrated formwork support device for upper and lower lintels of an ultra-wide window opening includes a template component one disposed at the upper lintel and a template component two disposed at the lower lintel. The template component one is detachably connected to a clamping component one, and the template component two is detachably connected to both clamping components one and two. A support component is disposed between the template component one and the template component two. The length of the support component is adjustable, and the connection position between the support component and the template component two is adjustable. By directly supporting the upper and lower lintels with formwork components one and two respectively, the upper and lower lintels can be poured simultaneously in one go. This eliminates the hardening and curing time for the lower lintel and the masonry construction time between the upper and lower lintels, improving construction efficiency. Each component can be disassembled and connected, facilitating quick installation and disassembly by construction workers, reducing construction difficulty and time. Formwork component one, supported at the upper lintel, is shaped by clamping components, and formwork component two, supported at the lower lintel, is shaped by clamping components one and two, resulting in a firm reinforcement effect, convenient installation and disassembly, no need for wall penetration reinforcement, saving construction steps and improving construction efficiency.

[0007] Furthermore, the template assembly 1 includes a U-shaped side plate 1, a bottom plate, and a side plate 2. The clamping assembly 1 is clamped to the top and side of the template assembly 1. The two ends of the bottom plate are respectively attached to the walls on both sides. The lengths of the side plate 1 and the side plate 2 are greater than the length of the bottom plate. At least two clamping assemblies 1 are provided on the template assembly 1 to enhance stability.

[0008] Furthermore, the clamping assembly includes an L-shaped clamp and a wedge plate that are inserted into each other. The vertical plate of the L-shaped clamp is attached to the outer wall of the side plate, and the horizontal plate is pressed on the top of the side plate and the side plate. The horizontal plate is provided with a strip hole for the wedge plate to be inserted.

[0009] Furthermore, the template component two includes a side plate three and a side plate four arranged in parallel, and both the side plate three and the side plate four are provided with grooves for engaging the clamping component two.

[0010] Furthermore, the clamping assembly two includes a U-shaped clamp and a wedge plate two that are inserted into each other. The vertical plate two of the U-shaped clamp is attached to the outer wall of the side plate four. The horizontal plate two and the horizontal plate three of the U-shaped clamp are both inserted into the groove. The horizontal plate two and the horizontal plate three are each provided with a strip hole two for the wedge plate two to be inserted.

[0011] Furthermore, the width of the open ends of the second and third horizontal plates is smaller than the width of the connecting ends of the second and third horizontal plates, which facilitates easy disassembly of the U-shaped clamp, resulting in a simple structure and convenient operation.

[0012] Furthermore, the support assembly includes an adjustable connecting rod and a sleeve. The top end of the rod is provided with a pressure plate that fits against the lower surface of the base plate, and the bottom end of the sleeve is detachably connected to the clamping assembly via a connector.

[0013] Furthermore, the connector includes a sleeve three with a perforated lug plate, a bolt passing through the perforated lug plate and the strip hole one in sequence and being positioned by a nut, the nut pressing on the lower surface of the horizontal plate one, the bottom of the sleeve one being inserted into the sleeve three, and the connection position between the sleeve three and the strip hole one being adjustable.

[0014] Furthermore, the connecting end of the rod is provided with an external thread, and the connecting end of the sleeve is provided with an internal thread, and the rod and the sleeve are threadedly engaged.

[0015] Furthermore, a horizontal support unit is provided perpendicularly to the support assembly. The horizontal support unit includes a sleeve two, both ends of which are threadedly connected to rod two and rod three. The outer ends of rod two and rod three are connected to pressure plates two for pressing against the side of the wall. A reinforcing member is provided between the horizontal support unit and the support assembly.

[0016] The specific beneficial effects of this utility model include:

[0017] 1. This utility model uses template component one and template component two to directly support the formwork at the upper and lower lintels respectively, which allows the upper and lower lintels to be poured directly and simultaneously in one go. This saves the hardening and curing time of the lower lintel and the masonry construction time between the upper and lower lintels, thus improving construction efficiency. All components can be disassembled and connected, which is convenient for construction personnel to quickly install and disassemble, reducing construction difficulty and time.

[0018] 2. The formwork component one at the upper lintel is shaped by the clamping components, and the formwork component two at the lower lintel is shaped by the clamping components one and two. The reinforcement effect is firm, and it is easy to install and dismantle. It does not require reinforcement through the wall, which saves construction steps and improves construction efficiency.

[0019] 3. The support position and length of the support components are adjustable, which can be flexibly adjusted according to actual construction needs, ensuring the stability of the formwork during concrete pouring, reducing the risk of deformation and displacement, and adapting to window openings of different sizes and shapes. It has strong versatility and adaptability, reduces the need for customized formwork, ensures accurate positioning of the formwork, reduces construction errors, improves the quality of concrete pouring, and ensures that the size and shape of the lintel meet the design requirements.

[0020] 4. The part of the capping beam anchored into the masonry uses U-shaped clamps. The second and third horizontal plates of the U-shaped clamps are designed with different sizes for easy disassembly after the concrete is poured. Grooves are reserved on the upper and lower sides of the third and fourth side plates of the part anchored into the masonry. After the U-shaped clamp is inserted into the groove, the second wedge plate is inserted into the end of the U-shaped clamp for fastening. The U-shaped clamps serve to reinforce the third and fourth side plates and also provide support for the anchored masonry, effectively ensuring the construction quality of the masonry above. After the concrete is poured and formed, the U-shaped clamps can be easily disassembled by simply tapping the smaller ends of the second and third horizontal plates. The structure is simple and the operation is convenient. Attached Figure Description
