Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a formwork support device for a bathroom curb that is poured in one go along with the main structure. Background Technology

[0002] Currently, aluminum alloy formwork systems are widely used in the construction of high-rise residential buildings, offering high construction efficiency and more controllable construction quality. However, in traditional methods, bathroom curbs often require secondary formwork and concrete pouring after the main structure is completed. If the construction joint is not thoroughly roughened or cleaned, seepage channels can easily form, leading to frequent bathroom leaks. Furthermore, the secondary construction process is complex, including roughening, rebar installation, formwork erection, and concrete transport, which not only extends the construction period by approximately 10% to 15% but also increases labor, material, and machinery costs.

[0003] On the other hand, bathroom spaces typically include multiple usable areas, such as the squat toilet area, shower area, and washbasin area. Due to drainage and waterproofing requirements, bathroom floors are often set at several different elevations: the lowest elevation is usually the squat toilet installation location, to allow for the pre-installation of drainage pipes and ensure smooth wastewater discharge; the area above the squat toilet is generally the shower area, to ensure smooth drainage; and the external washbasin area is usually higher than the bathroom floor level, but slightly lower than the hallway or living room floor, to prevent water from accumulating in the washbasin area and overflowing into the hallway or living room. Therefore, bathrooms often have two or three areas at different elevations.

[0004] In this situation, achieving the overall molding of different elevation areas of the bathroom in one go during the monolithic concrete pouring process, while ensuring the stability of the formwork support at the curb position, is a challenge in existing construction techniques. If suspended formwork is used, fixing the formwork is difficult, and problems such as formwork displacement and bulging are prone to occur, resulting in poor molding quality and a low pass rate. Utility Model Content

[0005] In view of this, the present invention proposes a formwork support device for a bathroom curb that is cast in one go along with the main structure. The specific technical solution is as follows: A formwork support device for a bathroom curb that is cast in one go along with the main structure includes interconnected aluminum formwork wall panels and exterior wall K-panels, aluminum alloy suspended formwork connected to the aluminum formwork wall panels, and a curb suspended formwork connected to the aluminum alloy suspended formwork. The exterior wall K-panel, the aluminum alloy suspended formwork, and the curb suspended formwork are connected by angle steel support plates. An aluminum formwork top plate is provided below the aluminum alloy suspended formwork and the curb suspended formwork. A mortar injection space is formed between the aluminum formwork top plate and the aluminum alloy suspended formwork and the curb suspended formwork. A steel reinforcement structure is provided in the mortar injection space.

[0006] Preferably, the reinforcing steel structure includes wall reinforcement bars disposed within the aluminum formwork wall panel and the outer wall K panel, slab surface reinforcement bars disposed on the aluminum formwork top panel, and inverted retaining wall reinforcement bars disposed in the inverted retaining wall formwork.

[0007] Preferably, the aluminum formwork top plate is fixed by a top plate support head and an adjustable single upright.

[0008] Preferably, the aluminum alloy hanging formwork includes aluminum alloy formwork parallel to the angle steel support plate below, and a first angle steel below the aluminum alloy formwork, the first angle steel being used to connect the parallel aluminum alloy formwork together.

[0009] Preferably, the inverted retaining wall formwork includes parallel inverted retaining wall formwork connected to the angle steel support plate, and the parallel inverted retaining wall formwork is connected to each other by an angle steel frame, which is formed by connecting multiple second angle steels.

[0010] Preferably, the angle steel frame is provided with an extension rod, and the extension rod is provided with fasteners.

[0011] Preferably, the bottom of the aluminum alloy hanging template is provided with a stainless steel bottom corner support plate.

[0012] Preferably, the bottom of the anti-sill hanging formwork is provided with bottom corner angle steel support plates.

[0013] Preferably, the lower part of the anti-sill hanging template is provided with stainless steel bottom corner irregular support plates and bottom corner angle steel support plates fixed by pins and pin pieces.

[0014] Preferably, the fastener consists of a screw, a nut, and a sleeve. The screw has threads at both ends that mate with the threaded sleeve, nuts are welded to both ends, and the middle section is located inside the floor slab.

[0015] Beneficial effects:

[0016] 1. Achieve one-time molding of different elevation areas in the bathroom.

[0017] This utility model combines aluminum formwork wall panels, exterior wall K-panels, aluminum formwork top panels, suspended formwork, and steel reinforcement structures to allow the toilet, shower area, and washbasin area inside the bathroom to be integrally formed in a single concrete pouring process, avoiding the cumbersome procedures of secondary formwork and secondary pouring required in traditional processes.

[0018] 2. Improve leak-proof performance

[0019] By using the reinforced design of the inverted retaining wall formwork, stainless steel bottom corner irregular support plates, and bottom corner angle steel support plates, the problems of grout leakage, formwork running, and formwork bursting during concrete pouring are effectively avoided, making the inverted retaining wall and the main structure form an integral whole, thus eliminating the hidden danger of leakage at construction joints from the root.

[0020] 3. Stable and reliable structure

[0021] This device uses angle steel supports and a fixing assembly consisting of screws, nuts and sleeves at the counter-sill position to lock the suspended formwork in both directions, ensuring that it will not move upward or shift during concrete pouring, thereby ensuring the overall stability of the formwork system and construction safety.

[0022] 4. High construction efficiency, saving construction time and costs.

[0023] By erecting the formwork system in one go, the processes of roughening, rebar installation, secondary formwork erection, and concrete transportation in secondary construction are eliminated, which can significantly shorten the construction period, reduce labor and material input, and reduce the cost of using construction elevators and machinery, resulting in outstanding overall economic benefits.
