Description

Technical Field

[0001] The utility model relates to the technical field of suspended formwork, and provides a suspended formwork tool for high and low floor slabs Background Art

[0002] In the construction of building houses, there are often high and low floor slabs, especially the suspended formwork in the toilet and balcony runs through the whole construction stage of the main structure. In the quality improvement of multi-storey and high-rise civil buildings, with the improvement of the one-time formwork support and pouring technology of carpenters, the quality of the main structure of the whole project has improved significantly, laying a good foundation for the quality improvement of the project structure. However, it is difficult to control the forming quality of the suspended formwork in the toilet, which has become a weak link in the quality improvement

[0003] At present, the commonly used suspended formwork method for toilets is to use wooden square timbers for suspended formwork. Its characteristic is to use spot welding of steel bars as a support to play a role in fixing the elevation, and use iron wires to fix the square timbers to form a framework. This method has the following disadvantages

[0004] 1. Since its bottom support is spot-welded steel bars, it is necessary to cut the steel bars in advance according to different heights, and it is impossible to eliminate the errors caused by the flatness of the formwork. At the same time, on-site hot work is required, which is time-consuming and laborious and there is a hidden danger of water seepage

[0005] 2. The square timbers fixed by iron wires are not reliable. During the concrete pouring process, the impact of the concrete, the collision of the vibrating rod, and the stepping and kicking of the pouring workers will all cause the square timbers to run out of position, formwork swelling, and deformation. The dimensional deviation is large, which directly affects the visual quality of the concrete forming

[0006] 3. During the construction process, the wooden square timbers are easy to bond with the concrete. During the formwork removal process, the wooden square timbers are easy to be damaged or even broken, resulting in material waste. Due to the concrete bonding, after the formwork is removed, it must be chiseled, and even local concrete forming has quality defects, and it needs to be chiseled and then poured twice, which affects the construction progress Content of the Utility Model

[0007] In order to solve the problems existing in the prior art, the utility model provides a suspended formwork tool for high and low floor slabs, which includes a framework and height-adjusting mechanisms arranged at the four corners of the framework. The height-adjusting mechanism includes a base, a bolt fixedly installed on the base, and a nut threadedly connected to the bolt. Installation holes are arranged at the four corners of the framework. The bolt passes through the installation hole, and the nut supports below the framework, and the error is eliminated by adjusting the height of the nut

[0008] Specifically, the base is made of PVC material, and through holes are arranged at the diagonals of the base

[0009] Specifically, the bolt and the nut are made of nylon material

[0010] Specifically, the aperture of the installation hole is larger than the aperture of the bolt

[0011] Specifically, at the four corners of the frame, the reinforcement members are welded above two adjacent side frames of the frame.

[0012] Specifically, the frame and the reinforcement members are made of square pipes by welding. The ends of the square pipes are sealed, and the cross-sectional area of the square pipes of the reinforcement members is smaller than that of the square pipes of the frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The high-low span slab formwork tool of the utility model is made by welding steel square pipes, eliminating the assembly gap and being integrally beautiful. It not only ensures the net size of the slab surface but also ensures the stiffness of the formwork system.

[0015] 2. The utility model overcomes the phenomena of formwork running and formwork bulging during the construction of traditional wooden square formwork, and the visual quality of the concrete forming is good.

[0016] 3. The mold of the utility model is convenient to install and remove, will not cause quality defects due to concrete adhesion, reduces the manual repair process, reduces the labor intensity, saves labor, speeds up the construction progress and improves work efficiency. The mold is simple to process and manufacture, can be used repeatedly, has no material waste phenomenon, and saves the construction cost.

[0017] 4. The utility model is fixed to the base by bolts. Compared with the traditional electric welding steel bar support, it does not require on-site hot work, and the construction is convenient and safe.

[0018] 5. The utility model uses disposable nylon bolts to support the square steel frame. For slab spans with different height differences, it can be adjusted by bolts, and at the same time, the error caused by the formwork flatness can be eliminated. The nylon bolts can prevent water seepage. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. The following describes the specific implementation of the present invention in detail with specific embodiments.

[0023] As Figure 1 - Figure 2 shown, a high-low span slab formwork hanging mold tool includes a frame 1 and height adjustment mechanisms provided at the four corners of the frame 1. The frame 1 is made of square tubes welded together, and the ends of the square tubes are sealed to prevent concrete from pouring into the square tubes. Reinforcing members 2 are provided at the four corners of the frame 1. The reinforcing members 2 are welded above two adjacent side frames of the frame 1. The reinforcing members 2 are also made of square tubes with sealed ends. The cross-sectional area of the square tubes of the reinforcing members 2 is smaller than that of the square tubes of the frame 1. The reinforcing members 2 are used to reinforce the frame 1. At the same time, after the concrete is formed, the reinforcing members 2 are used as handles to remove the frame 1 from the concrete.

[0024] The height adjustment mechanism includes a base 6, a bolt 4 fixedly installed on the base 6, and a nut 5 threadedly connected to the bolt 4. Installation holes 3 are provided at the four corners of the frame 1. The diameter of the installation holes 3 is slightly larger than the diameter of the bolt 4. For example, the diameter of the installation holes 3 is 35 mm, and the diameter of the bolt 4 is 32 mm. The bolt 4 passes through the installation holes 3, and the nut 5 supports below the frame 1. The base 6 is made of PVC. Perforations 7 are provided at the diagonal corners of the base 6. Woodworking nails pass through the perforations 7 to fixedly install the base 6 on the formwork, fixing the position of the frame 1, overcoming the problems of formwork displacement and formwork bulging during traditional wooden square formwork hanging mold construction, and the appearance quality of the formed concrete is good. The height of the frame 1 can be adjusted by rotating the nut 5 according to the thickness of the concrete. This height adjustment mechanism can eliminate the errors caused by the unevenness of the lower formwork. When hanging a formwork on a slab span with a height difference, the frame 1 can be leveled by rotating the nut 5 to eliminate the errors caused by the slab span, so as to ensure the flatness of the concrete slab surface.

[0025] The bolt 4 and the nut 5 are made of nylon to prevent water seepage. After the concrete is poured, the part of the bolt 4 above the concrete surface can be cut flat with a handheld grinder.

[0026] During pouring, determine the position of the hanging mold, use woodworking nails to fix the hanging mold tool on the formwork, and rotate the nut 5 according to the installation position and the concrete pouring height to adjust the height of the frame 1 and level the frame 1.

[0027] During disassembly, the bolt 4 and the nut 5 are buried in the concrete. Taking the reinforcement member 2 as a handle, the frame 1 is pulled upward to disassemble the frame 1 from the concrete. The bolt 4 and the nut 5 made of nylon can prevent water from seeping through the bolt 4 to the lower layer. The part of the bolt 4 above the concrete surface is cut flat using a hand-held grinding machine. The disassembly is simple, reducing the manual repair process. The frame 1 can be reused without wasting materials.

[0028] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
