Description

Technical Field

[0001] The utility model relates to the technical field of building template reinforcement, in particular to a gasket welded pull rod. Background Art

[0002] At present, domestic rubber spiral tie rods have been adopted by many large central enterprises. The technology is relatively mature, the intellectual property rights of the general direction have been applied for registration, and the key technical indicators are mature. However, if the side beam is large and the reinforcement is not dense, it will cause the concrete side beam to explode. The gasket welded tie rod can well avoid this phenomenon.

[0003] At present, the application of gasket-welded tie rods in the Guangdong Rongyi Intelligent Industrial Park project focuses on quality management and the comparison between concrete forming effects and leakage risks of traditional iron wire reinforcement, which has played a good promoting role.

[0004] In the construction of buildings, the side beam molds cannot be properly reinforced with ordinary tie screws, and the traditional method is to use iron nails and iron wires for reinforcement. When iron nails and iron wires are used to reinforce the side beam molds, it is easy to make the cross-sectional size of the side beam difficult to control, and after pouring, it is easy to have quality problems such as mold expansion and side beam deformation, and personnel need to be arranged to remove the iron wires after demolding.

[0005] During the concrete pouring process, the chiseling and repairing and leakage of concrete caused by the expansion of the mold will cause pollution to the facade of the building, and the failure to remove the iron wire in place will cause unnecessary leakage problems. In view of this phenomenon, the utility model proposes a gasket welded pull rod. Utility Model Content

[0006] The utility model aims to solve the defects in the prior art and proposes a gasket welded pull rod.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A gasket-welded pull rod comprises a pull rod, one end of which is provided with a gasket, the gasket is radially connected to the circumferential surface of the one end of the pull rod, and four positioning holes are symmetrically opened around the gasket.

[0009] Furthermore, the gasket is welded and fixed on the circumferential surface of one end of the pull rod.

[0010] Furthermore, the gasket is detachably connected to the circumferential surface of one end of the pull rod, and two support plates are symmetrically welded and fixed on the surface of the gasket. A sleeve is rotatably installed on the side where the two support plates are close to each other, and nuts are welded and fixed to the ends of the two sleeves close to each other. The ends of the two sleeves away from each other extend to the outside of the support plate and are welded with a retaining ring, and the end of the pull rod close to the gasket is threadedly connected to the nut.

[0011] Furthermore, the inner diameter of the sleeve is larger than the outer diameter of the pull rod, the retaining ring is welded and fixed to the outer circumference of the sleeve end, the support plate is provided with a mounting hole, and the inner diameter of the mounting hole is equal to the outer diameter of the sleeve.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model can well solve the quality problem caused by the inability to effectively reinforce the side formwork at the cast-in-place position on the top of the building's exterior wall, and also solves secondary operations such as chiseling and repairing due to expansion of the formwork and cleaning of the facade pollution caused by leakage, as well as the hidden danger of leakage caused by traditional iron wire reinforcement.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0021] Embodiment 1

[0022] Reference Figure 1A gasket-welded tie rod comprises a tie rod 1, a gasket 2 is mounted on one end of the tie rod 1, the gasket 2 is radially connected to the circumferential surface of one end of the tie rod 1, and four positioning holes 3 are symmetrically opened around the gasket 2. The diameter of the tie rod 1 is 12 mm, and the size of the gasket 2 is 5 cm*5 cm*3 mm.

[0023] In the first embodiment, the gasket 2 is welded and fixed on the circumferential surface of one end of the pull rod 1 .

[0024] Weld one end of the tie rod 1 to the gasket 2 to fix them. Next, after the main formwork and steel bars are installed, use nails to position and reinforce the gasket 2 through the positioning hole 3. Finally, use the tie rod 1 to reinforce the side formwork.
