[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] In the utility model, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0023] Please refer to Figure 1 , which is a schematic diagram of the structure of a one-way screw used for supporting the formwork in one embodiment of the utility model. Figure 1 As shown, the one-way screw rod for supporting the formwork comprises: a rod body 1, a control component 3 and a construction component 2 respectively arranged at the first end 101 and the second end 102 of the rod body 1; wherein the construction component 2 comprises: two folding rods 21 and two springs 22 arranged on the rod body 1, one end of each spring 22 is arranged on the rod body 1, and the other end is connected to a folding rod 21; the control component 3 comprises: a buckle 31 and two steel wires 32; one end of each steel wire 32 is connected to the buckle 31 arranged on the rod body 1, and the other end passes through a spring 22 and is connected to a folding rod 21; the buckle 31 is adjusted based on the length of the two steel wires 32 to realize the switching of the two folding rods 21 between the folded state and the extended state.

[0024] The one-way screw designed based on the utility model is used for formwork construction. When there is no external frame to fix the side formwork at the high-altitude edge, the construction workers can control the one-way screw to extend and remove it from one side by standing in the safe area on the floor, without having to step into the high-altitude edge area, thereby effectively preventing the occurrence of high-fall hazards and achieving safe construction.

[0025] Further, such as Figure 1 As shown, the one-way screw further includes: a locking assembly 4, which is arranged on the body of the first end 101 of the rod body 1; specifically, the locking assembly 4 includes: a butterfly clip 41 and a nut 42, both of which are sleeved on the outside of the rod body 1. The butterfly clip 41 is a tool for locking and anchoring the template tie rod, which anchors the tie rod by using the resistance generated when the clamp wedge-shaped pin clamps the tie rod. Since the butterfly clip 41 is an existing construction equipment, its structure is not described in detail.

[0026] Preferably, in order to improve the structure of the one-way screw, a slot 11 is provided on the main body of the one-way screw near the second end 102 of the rod body 1, and the construction component 2 is arranged in the slot 11. Specifically, the folding rod 21 and the spring 22 can be received in the slot 11 to protect them while facilitating the recycling of the entire one-way screw.

[0027] The construction assembly of the one-way screw of the utility model is divided into three states, please refer to Figures 2 to 4 , as follows:

[0028] 1) Folding state / closed state: the two folding rods 21 are in a folding state, the two springs 22 are in a compressed state, and are folded and stored in the card slot 11 .

[0029] Specifically, the dynamic process of adjusting this state is as follows: the steel wire 32 is pulled back at the buckle 31, and the spring 22 contracts and moves forward to retract the folding rod 21 into the slot 11. It can be extended from the telescopic end and pulled out backward when removed.

[0030] 2) Semi-extended state / semi-closed state: The two folding rods 21 are in a semi-extended state, with a "V" shape, and the two springs 22 are in a semi-compressed state. The angle between the two folding rods 21 and the rod body 1 is an acute angle and extends out of the slot 11. (This state is a transitional state between the folded state and the extended state)

[0031] 3) Extended state: the two folding rods 21 are in an extended state, the two springs 22 are in a natural state, and the two folding rods 21 are vertical and extend out of the slot 11. That is, after the front buckle is released, the spring automatically returns to a natural unstressed state from a compressed state, and this process pushes the folding rod back to an extended state.

[0032] Specifically, the dynamic adjustment process of this state is as follows: after the one-way screw is extended to the other side, the buckle 31 is released, and the spring 22 is used to extend back to the natural state, and the folding rod 21 is pushed back to unfold.

[0033] It can be understood that the above examples are merely examples listed for a better understanding of the technical solutions of the embodiments of the present application, and are not intended to be the sole limitation to the embodiments.

[0034] The principle of the one-way screw used for supporting formwork in the utility model is as follows:

[0035] refer to Figures 2 to 4 The one-way screw uses the spring expansion principle to expand and fold the folding rod of the one-way screw. During construction, workers on the safe side of the floor can control the second end 102 of the one-way screw to extend and pull out the construction. Workers do not need to go to the outside of the edge for construction, ensuring safe construction.

[0036] In order to better understand the application principle of the one-way screw of the utility model, the following is an explanation in combination with its use process, as follows:

[0037] ① Retract the folding rod 21 into the card slot 11;

[0038] ② Fasten the buckle 31 and extend the screw from the side mold safety area to the outside of the edge;

[0039] ③ Release the buckle 31, and use the elastic force of the spring 22 to automatically return to the natural state to push the folding rod 21 to unfold;

[0040] ④ Tighten the butterfly clip 41 at the inner end of the side mold floor, and the installation is completed;

[0041] ⑤ When removing, pull the steel wire 32 back from the buckle 31, and the spring 22 contracts to pull the folding rod 21 back into the slot 11;

[0042] ⑥Pull out the one-way screw from the safe side inside the floor.

[0043] In summary, in the one-way screw for supporting formwork provided by the utility model, the one-way screw comprises: a rod body, a control assembly and a construction assembly respectively arranged at the first end and the second end of the rod body; wherein the construction assembly comprises: two folding rods and two springs arranged on the rod body, one end of each spring is arranged on the rod body, and the other end is connected to a folding rod; the control assembly comprises: a buckle and two steel wires; one end of each steel wire is connected to the buckle arranged on the rod body, and the other end is connected to a folding rod after passing through a spring; the buckle is adjusted based on the length of the two steel wires to realize the switching of the two folding rods between the folded state and the extended state. Through the structural design of the two ends of the one-way screw, different functions are given to the two ends of the same single screw, and the installation and removal of the unilateral control screw are supported. Workers do not need to go to the outside of the edge for construction. It is suitable for formwork construction without external frames at high altitude edges, effectively reducing construction safety hazards and ensuring safe construction.
