[0002] With the continuous development of the construction industry, more and more buildings pay attention to the beauty of the building appearance. However, when designing the building appearance, some pilasters and small cavity structures are mostly used. The structure has thin walls, small internal space, and is mostly concrete integrated.

[0003] The existing technology is to use ordinary formwork to support the construction of small space structures. First, the inner formwork is supported, and then the outer formwork is supported and concrete is poured. However, when removing the formwork in this way, the space is too small and personnel cannot enter, making it difficult to remove the formwork. In many cases, the formwork is left inside and is not removed. However, if it is not removed, there is a risk of it falling, which will have a certain impact on the original quality and surrounding safety. Summary of the invention

[0004] The utility model aims to solve the problems raised in the background technology and provides a small space structure quick-disassembly mold device.

The horizontal toothed square tube is slidably inserted in the horizontal buckle square tube; horizontal buckleless square tubes are vertically fixed at both ends of the lower left angle steel, and horizontal toothless square tubes are vertically fixed at both ends of the lower right angle steel, and the horizontal toothless square tube is slidably inserted in the horizontal buckleless square tube; the top surface of the horizontal toothed square tube is provided with clamping teeth arranged along its length direction, and a lever mouth is opened at the top surface of the horizontal buckle square tube near the tube mouth, and a connecting shaft is fixed in the lever mouth, and a movable tooth is rotatably connected to the connecting shaft, and torsion springs are mounted on both ends of the connecting shaft, one end of the torsion spring is fixedly connected to the horizontal buckle square tube, and the other end is fixedly connected to the movable tooth, and the movable tooth is clamped on the clamping tooth under the action of the elastic force of the torsion spring.

[0007] Furthermore, a circle of cavity templates is arranged around the outside of the four vertical supporting steel pipes.

[0008] Furthermore, a plurality of tension springs are evenly connected between the upper left angle steel and the upper right angle steel, and a plurality of tension springs are evenly connected between the lower left angle steel and the lower right angle steel.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model provides a small space structure quick-disassembly mold device, through its structural design, the cavity template is supported according to the size of the small cavity, and then the size of the overall structure is adjusted according to the size of the small cavity. When adjusting the size, the construction personnel pull the angle steel on both sides outwards, and the angle steel moves on both sides outwards to drive the steel pipe to move, and at the same time drives the horizontal buckle square tube and the horizontal toothed square tube as well as the horizontal buckleless square tube and the horizontal toothless square tube to move on both sides outwards respectively. At this time, the horizontal toothed square tube is pulled outwards from the horizontal buckle square tube. When pulling out, the tooth inclined surface of the horizontal toothed square tube pushes the movable tooth to rotate on the connecting shaft, and the rotation of the movable tooth allows the horizontal toothed square tube to be pulled out from the horizontal buckle square tube. When the overall structure is adjusted to a suitable size, the angle steel is stopped from being pulled, and the torsion spring drives the movable tooth to reset and be clamped in the clamping tooth, clamps the horizontal toothed square tube, and makes the horizontal toothed square tube unable to reset. At this time, the utility model is placed on the inner side of the cavity template, and the cavity template is supported. After the utility model is supported and set up in the small cavity, the outer formwork can be installed. After the outer formwork is installed, concrete can be poured. After the concrete reaches the demolding requirements, the utility model can be removed. When removing, pull the pull rope, and the pull rope will pull up the two movable teeth through the wrench at the same time, so that the movable teeth leave the clamping teeth. At this time, the horizontal toothed square tube can be re-inserted into the horizontal buckle square tube to complete the demolding. Finally, the utility model can be lifted off and wait for the next use. Compared with the prior art, the utility model is not only simple and convenient to support and remove the mold, but also solves the problem of difficult demolding in a small space, and improves the safety quality of the structure.

The utility model can be removed after the concrete reaches the demoulding requirements. When removing, pull the pull rope 18, and the pull rope 18 rotates and pulls up the movable teeth 12 on the two horizontal buckle square tubes 6 at the same time. At this time, the horizontal square tube with teeth 7 can be re-inserted into the horizontal square tube with buckle 6 and the horizontal square tube without teeth 9 can be re-inserted into the horizontal square tube without buckle 8 to complete the demoulding. The tension spring 15 on the angle steel can make the movable teeth 12 automatically inserted into the horizontal square tube with buckle 6 and the horizontal square tube without teeth 9 automatically inserted into the horizontal square tube without buckle 8 when the construction personnel drive the movable teeth 12 to rotate. Finally, the utility model can be lifted off and wait for the next use. The lifting holes 16 on the angle steel are convenient for moving using lifting equipment, thereby improving construction efficiency.
