Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a hanging formwork which is convenient for disassembly and assembly. Background Art

[0002] During the construction of concrete structures, lowered slabs are often used in bathrooms, kitchens, and balconies to prevent water from overflowing. Generally, a height difference of about 5 cm is designed in bathrooms, kitchens, and balconies.

[0003] When dismantling existing hanging formwork, construction workers generally gradually insert a crowbar between the concrete and the formwork from the edge gap until the formwork is completely detached. Due to the large overall area of the formwork, the friction resistance between the formwork and the concrete is large. Inserting the crowbar from the edge can easily damage the formwork and make it difficult to peel off. At the same time, the initial contact area of the crowbar is limited, making dismantling time-consuming and labor-intensive, and also affecting the forming effect of the concrete.

The strip slider is slidably installed between the two limit plates. Under the action of the elastic component, the limit plate retracts into the mounting groove or slides out of the mounting groove and abuts against the strip slider.

[0006] Furthermore, the elastic component includes multiple telescopic rods and multiple compression springs, the telescopic rods and the compression springs correspond one to one, and the multiple telescopic rods are arranged at intervals along the length direction of the limit plate.

The rollers abut against the strip slider, and the rotation direction of the rollers is consistent with the sliding direction of the strip slider.

[0008] Furthermore, a plurality of accommodating grooves are provided at intervals along the length direction of the strip slider on one side close to the concrete, and a plurality of mounting holes connected to the accommodating grooves are provided on the other opposite side, the accommodating grooves and the mounting holes corresponding to each other one by one, and a plurality of second threaded holes connected to the mounting holes are provided on the other side of the fixing plate away from the concrete, the second threaded holes are staggered with the first threaded holes, a connecting plate is slidably installed in the accommodating groove, a connecting rod is slidably installed in the mounting hole, one end of the connecting rod is rotatably connected to the connecting plate, and the other end extends out of the second threaded hole, and an external thread is provided on the end of the connecting rod away from the connecting plate, and the external thread is threadedly connected to the second threaded hole.

[0010] Beneficial effects:

[0011] 1. The present invention, through the arrangement of a fixed plate, multiple chutes, strip sliders, and fastening bolts, can divide the formwork of a hanging formwork into multiple areas for separate assembly and disassembly. This reduces frictional resistance between the formwork and concrete during disassembly, facilitates insertion of a crowbar, and increases the contact area between the crowbar and the formwork, making formwork disassembly more time-efficient and labor-efficient, and preventing damage to the formwork. During installation, the fixed plate is first secured by a fixing mechanism, and then multiple strip sliders are slid from the top or bottom into the chutes, and finally, the fastening bolts are tightened. During disassembly, the fastening bolts are first removed, and then the strip sliders are struck from the top or bottom to separate them from the concrete. The strip sliders are then slid out of the chutes, and finally, the crowbar is inserted into the chutes to remove the fixed plate. Because the contact area between the strip sliders and the concrete is smaller than that of the entire formwork, the frictional resistance between the two is also smaller, making it less likely to drag the surrounding concrete during disassembly. Consequently, quality issues such as looseness, defects, and uneven edges on the concrete structure's formwork surface will not occur.

[0012] 2. In the present invention, the setting of the mounting groove, the elastic component and the limit plate can improve the fixing effect of the strip slider, and at the same time can facilitate the disassembly of the strip slider; combined with the setting of multiple telescopic rods and multiple compression springs, the elastic force of the compression springs can be used to achieve adaptive clamping of the strip slider, and at the same time can facilitate the separation of the limit plate from the strip slider; through the setting of multiple rollers, the friction resistance between the strip slider and the limit plate can be reduced, further facilitating the disassembly of the strip slider.

[0013] 3. In the present invention, by providing the accommodating groove, the mounting hole, the second threaded hole, the connecting plate and the connecting rod, the strip slider and the fixed plate can be easily disassembled by screwing together, thereby improving the disassembly efficiency and the molding quality of the concrete. Specifically, during installation, the connecting rod is rotated to make the connecting plate flush with the surface of the strip slider, ensuring that the concrete surface is flat during pouring. When pouring is completed and the formwork needs to be removed, the connecting rod is rotated to make the connecting plate slide out of the accommodating groove and squeeze against the concrete surface, thereby causing a certain amount of looseness between the strip slider and the concrete or even causing it to completely detach, which can also drive the fixed plates on both sides of the strip slider to loosen, further avoiding concrete quality problems.

[0014] 4. In the present invention, the setting of the stop block can limit the sliding displacement of one side of the connecting plate, quickly fix the position of the connecting plate, and avoid the height difference between the surface of the connecting plate and the surface of the strip slider.
