Description

Technical Field

[0001] This application relates to the field of construction, and in particular to a rotating steel rod structure. Background Technology

[0002] In building construction, steel rods can be used to connect steel mesh and fix it in the concrete structure, thereby improving the strength and stability of the building.

[0003] When connecting steel rods to the reinforcing bars in the steel mesh, they are usually tied with wire. However, since the steel rods need to be removed for reuse after the concrete structure is poured, the method of tying with wire makes it very inconvenient to remove the steel rods from the concrete structure. Utility Model Content

[0004] To address the problem that the method of binding with wire makes it very inconvenient to extract the steel rod from the concrete structure, this application provides a rotary steel rod structure.

[0005] The rotary steel rod structure provided in this application adopts the following technical solution:

[0006] A rotary steel rod structure includes a steel rod and a clip. The clip is connected to and detached from the steel rod through a rotary connection structure. The clip is connected to the reinforcing bars in the steel mesh through a snap-fit ​​structure. The surface of the steel rod is covered with a hot-melt layer, which can prevent the concrete structure from contacting the steel rod.

[0007] By adopting the above technical solution, when connecting the steel bars in the steel wire mesh, the clips are first connected to the steel wire through a rotating connection structure, and then the clips are clamped to the steel bars in the steel wire mesh. After the concrete structure is poured, the steel wire is heated to melt the hot melt layer, and then the steel wire is rotated to disassemble from the clips. Then the steel wire is pulled out of the concrete structure. Compared with the method of binding with wire, the solution of this application improves the convenience of separating the steel wire from the steel wire mesh and pulling it out of the concrete structure.

[0008] In one specific implementation, the steel rod includes a tip and a rod body, the tip and the rod body are connected by a neck, and a connecting groove is formed between the tip and the rod body;

[0009] The rotary connection structure includes a connecting part disposed on the buckle, the buckle having a placement groove for the tip to be inserted, and the connecting part being rotatably inserted into the connecting groove to form a snap-fit ​​between the connecting part and the connecting groove.

[0010] By adopting the above technical solution, when installing the buckle onto the steel rod, the tip is first inserted into the placement groove, and then the buckle is rotated so that the connecting part is rotated into the connecting groove, forming a snap-fit ​​between the buckle and the steel rod, thereby improving the convenience of connecting the buckle and the steel rod.

[0011] In one specific implementation, the buckle is provided with a connecting hole for the tip to pass through and be inserted into the placement slot, and the connecting part is located on both sides of the connecting hole.

[0012] By adopting the above technical solution, the tip passes through the connecting hole and is inserted into the placement groove. Then, the connection between the connecting parts on both sides of the connecting hole and the connecting groove is used to improve the stability of the buckle and the steel rod connection.

[0013] In one specific implementation, the tip protrudes radially outward to form two opposing protrusions, the connecting portion corresponds one-to-one with the protrusions, and the connecting portion can be rotatably inserted between the protrusions and the drill body.

[0014] In one specific implementation, the protrusion is tightly fitted with the wall of the placement groove.

[0015] By adopting the above technical solution, the stability of the connection between the buckle and the steel rod is improved by utilizing the tight fit between the protrusion and the placement groove.

[0016] In one specific implementation, an observation port communicating with the placement slot is provided on the outer side wall of the buckle.

[0017] By adopting the above technical solution, the position of the protrusion can be determined by using the observation port, which facilitates the observation of the engagement status between the buckle and the steel rod.

[0018] In one specific implementation, the snap-fit ​​structure includes an elastic card fixedly disposed on the buckle, and the elastic card and the drill bit can form a slotting space for inserting the reinforcing bars in the reinforcing mesh, and the elastic card can clamp and fix the reinforcing bars in the reinforcing mesh in the slotting space.

[0019] By adopting the above technical solution, when connecting the buckle to the steel bars in the steel mesh, the deformation of the elastic card is used to insert the steel bars into the locking space, and then the elastic card is reset to lock and fix the steel bars, thereby improving the convenience of connecting the buckle to the steel mesh.

[0020] In one specific implementation, the buckle is provided with a high-temperature resistant insulating sleeve, which is sleeved on the drill bit so that the reinforcing bars in the reinforcing mesh can be pressed against the insulating sleeve.

[0021] By adopting the above technical solution, when heating the steel rod with electricity, the insulating sleeve is used to block the connection between the reinforcing bar and the steel rod, thereby reducing the power consumption when heating the steel rod with electricity.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When connecting the steel bars in the steel wire mesh, the clips are first connected to the steel wire through a rotating connection structure. Then, the clips are clamped to the steel bars in the steel wire mesh. After the concrete structure is poured, the steel wire is heated to melt the hot melt layer. Then, the steel wire is rotated to disassemble the clips. Finally, the steel wire is pulled out of the concrete structure. Compared with the method of binding with wire, the present application solution improves the convenience of separating the steel wire from the steel wire mesh and pulling it out of the concrete structure.

[0024] 2. By heating and melting the hot melt layer, the ease of rotating the steel rod is improved;

[0025] 3. When heating the steel rod by electricity, use an insulating sleeve to prevent the reinforcing bar from being connected to the steel rod, thereby reducing the power consumption when heating the steel rod by electricity. Attached Figure Description

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] This application discloses a rotary steel rod structure.

[0031] Reference Figure 1 , Figure 2A rotary steel rod structure includes a steel rod 1 and a clip 2. The clip 2 is located at the end of the steel rod 1 and is detachably connected to the steel rod 1 via a rotary connection structure 3. In this embodiment, the clip 2 is made of plastic. The steel rod 1 includes a tip 11 and a rod body 12. The rod body 12 is cylindrical and is fixedly connected to the tip 11 via a cylindrical neck 13. The clip 2 is connected to the reinforcing bars in the steel mesh via a snap-fit ​​structure 4. The outer surface of the rod body 12 is covered with a hot-melt layer 5. In this embodiment, the hot-melt layer 5 can be one of paraffin wax or polyethylene. The hot-melt layer 5 is melted by heating the rod body 12. In this embodiment, the rod body 12 is heated by energizing it; in other embodiments, it can also be heated by burning.

[0032] When connecting the reinforcing bars in the steel mesh of the steel rod 1, the clip 2 is first connected to the steel rod 1 via the rotating connection structure 3. Then, the clip 2 is clamped to the reinforcing bars in the steel mesh. After the concrete structure is poured, the steel rod 1 is heated by electricity to melt the heat-melting layer 5, improving the ease of rotation of the steel rod 1. Then, the steel rod 1 is rotated to disassemble from the clip 2, and then the steel rod 1 is pulled out of the concrete structure. Compared with the method of binding with wire, the present application scheme improves the convenience of separating the steel rod 1 from the steel mesh and pulling it out of the concrete structure.

[0033] Reference Figure 1 , Figure 2 The tip 11 has a flat design, which causes the tip 11 to bulge outward along the radial direction to form two opposing protrusions 111. A connecting groove 112 is formed between the two protrusions 111 and the end face of the drill body 12. The rotary connection structure 3 in this embodiment includes a connecting part 31. The buckle 2 is cylindrical. The rear end of the buckle 2 forms a placement groove 34 for the tip 11 to be inserted. The front end of the buckle 2 has a strip-shaped connecting hole 32. The connecting part 31 is located on both sides of the connecting hole 32. The length between the two protrusions 111 is greater than the width of the connecting hole 32, ensuring that the connecting part 31 can be rotatably inserted into the connecting groove 112.

[0034] When installing the clip 2 and the steel rod 1, the protrusion 111 and the tip 11 are inserted through the connecting hole 32 into the placement groove 34. Then, the clip 2 is rotated so that the two connecting parts 31 are inserted into the corresponding connecting grooves 112, thus completing the engagement of the clip 2 and the steel rod 1. When disassembling the clip 2 and the steel rod 1, the steel rod 1 is rotated to align the two protrusions 111 with the connecting hole 32. Then, the steel rod 1 is pulled out so that the tip 11 is pulled out of the clip 2, thus completing the disassembly of the clip 2 and the steel rod 1, thereby improving the convenience of detachable connection between the steel rod 1 and the steel mesh.

[0035] Reference Figure 1 , Figure 2To improve the stability of the connection between the buckle 2 and the steel rod 1, when the tip 11 is inserted into the placement groove 34, the protrusion 111 fits tightly with the groove wall of the placement groove 34. An observation port 33 communicating with the placement groove 34 is provided on the outer side wall of the buckle 2. The position of the protrusion 111 can be determined by the observation port 33, which facilitates the observation of the engagement status between the buckle 2 and the steel rod 1.

[0036] Reference Figure 1 , Figure 2 In this embodiment, the snap-fit ​​structure 4 includes an elastic card 41 fixedly mounted on the snap-fit ​​2. The elastic card 41 is integrally formed with the snap-fit ​​2, and an arc-shaped groove is formed on the elastic card 41 to cooperate with the reinforcing bar. A high-temperature resistant insulating sleeve 42 is fixedly mounted on the snap-fit ​​2. The insulating sleeve 42 can be made of polyimide, ceramic fiber material, or silicone rubber. The insulating sleeve 42 is sleeved on the end of the drill bit 12, and a locking space is formed between the elastic card 41 and the sleeve wall of the insulating sleeve 42. The reinforcing bar of the reinforcing mesh is inserted into the locking space through the elastic deformation of the elastic card 41, and then the elastic card 41 presses the reinforcing bar tightly onto the insulating sleeve 42, thereby clamping and fixing the insulating sleeve 42 and improving the convenience of connecting the snap-fit ​​2 and the reinforcing mesh. When the drill bit 1 is heated by electricity, the insulating sleeve 42 is used to prevent the reinforcing bar from conducting with the drill bit 1, reducing the power consumption when the drill bit 1 is heated by electricity.

[0037] The implementation principle of the rotary steel rod structure in this application embodiment is as follows: When connecting the steel bars in the steel mesh of the steel rod 1, the protrusion 111 and the tip 11 are inserted into the placement groove 34 through the connection hole 32. Then, the buckle 2 is rotated so that the two connecting parts 31 are respectively inserted into the corresponding connection grooves 112, thus completing the buckle 2 and the steel rod 1. The steel bars of the steel mesh are inserted into the locking space through the elastic deformation of the elastic card 41. Then, the elastic card 41 presses the steel bars onto the insulating sleeve 42, thus clamping and fixing the insulating sleeve 42. After the concrete structure is poured, the steel rod 1 is heated to melt the hot melt layer 5. The steel rod 1 is rotated to align the two protrusions 111 with the connection hole 32. Then, the steel rod 1 is pulled out so that the tip 11 is pulled out of the buckle 2, thus completing the disassembly of the buckle 2 and the steel rod 1. Then, the steel rod 1 is pulled out of the concrete structure. Compared with the method of binding with wire, the solution of this application improves the convenience of separating the steel rod 1 from the steel mesh and pulling it out of the concrete structure.
