Abstract
Description
Technical Field
[0001] The utility model belongs to the field of construction of steel-encased wood, and particularly relates to an assembly connection claw for steel-encased wood. Background Technique
[0002] In traditional construction, the construction method for cast-in-place concrete formwork generally uses steel or wooden beams to assemble into formwork brackets, and uses steel or wooden rods to build scaffolding to form bracket supports and combines with multi-layer boards for concrete construction. Traditional building formwork is actually a kind of plywood. The difference is that building formwork is specially produced for building, bridge, tunnel, water conservancy projects and other buildings to pour concrete. After the traditional building formwork is formed, it is necessary to support the back of the formwork to prevent the formwork from deforming during construction and affecting the forming effect. In the prior art, the back support structure of the formwork usually selects steel-encased wood for support, and then relatively fixes the positions of multiple steel-encased woods through aluminum formwork back ribs. During construction, the steel-encased wood and the steel back rib on the back of the formwork are usually connected by nailing, which requires workers to nail step by step. The operation is cumbersome, the labor intensity is high, and the nailing quality is uncontrollable. After nailing is completed, it will cause certain damage to the steel-encased wood, making the steel-encased wood unable to be recycled, resulting in waste of parts and increasing the construction cost. Summary of the Invention

[0026] Such as Figures 1 - 4As shown in the figure, the ladle wood assembly connecting claw includes a connector body 1, and the connector body 1 is used to position and connect the steel back rib 2 and the ladle wood 3. A positioning support rod 4 is arranged on one side of the connector body 1. A positioning groove 21 is provided on the steel back rib 2. The periphery of the positioning support rod 4 can abut against the inside of the positioning groove 21. A threaded hole 12 is provided on the positioning support rod 4, and a screw rod 5 is arranged in the threaded hole 12. One end of the screw rod 5 can abut against the periphery of the ladle wood 3. An installation hole is provided on the connector body 1, and a hook 7 is arranged in the installation hole. The hook 7 can be clamped to the steel back rib 2. The steel back rib 2 is connected to the connector body 1 through the hook 7, and then the ladle wood 3 is connected to the connector body 1 through the screw rod 5. The nailing link can be omitted at the operation site, thus improving the production and assembly efficiency. Since nailing is omitted, the damage to the ladle wood 3 body is also avoided, and the turnover rate is improved.
[0027] The cross-section of the positioning support rod 4 is an L-shaped structure. The inner side of the L-shaped structure and the outer side of the connector body 1 form a U-shaped groove 13. The periphery of the ladle wood 3 is located in the U-shaped groove 13. The relative position of the ladle wood 3 is positioned through the U-shaped groove 13, and then the relative position of the ladle wood 3 is fixed through the screw rod 5. A cushion plate 6 is arranged at one end of the screw rod 5. The screw rod 5 abuts against the periphery of the ladle wood 3 through the cushion plate 6. The cushion plate 6 can increase the contact area between the screw rod 5 and the ladle wood 3 and prevent the screw rod 5 from damaging the outer surface of the ladle wood 3.
[0028] As Figure 2 shown in the figure, the cross-section of the hook 7 is a T-shaped structure. The large end of the hook 7 is clamped to one end of the steel back rib 2. A through hole 11 is provided on the connector body 1. The small end of the hook 7 passes through the steel back rib 2 and the through hole 11 in sequence and is then threadedly connected to a nut 9. During implementation, a hook plate 8 is arranged on each side of the large end of the hook 7. An angle is provided between the hook plate 8 and the hook 7. The periphery of the steel back rib 2 is located between the two hook plates 8. The two hook plates 8 are used to position the periphery of the steel back rib 2 and prevent the hook 7 from rotating relative to the steel back rib 2. During assembly, it is convenient for the staff to tighten the connecting nut 9. In this embodiment, the hook plate 8 and the hook 7 are integrally welded structures.
[0029] Steel clad wood assembly connecting claw. The connecting piece body 1 is integrally bent from a profile. One side is provided with a through hole 11 for passing the clamping hook 7, and the other side is provided with a threaded hole 12 for fixing the screw rod 5. A backing plate 6 is welded on the screw rod 5. The backing plate 6 can increase the contact area when connecting with the steel clad wood 3 and reduce the damage to the steel clad wood 3. During the manufacturing process, the screw rod 5 is passed through the connecting piece body 1 in advance and then the backing plate 6 is welded to fix it. The clamping hook 7 is of a T-shaped double hook head structure, and the outside of the T-shaped bottom is provided with threads. When in use, the connecting piece body 1 and the screw rod 5 are combined together in advance as a whole. The U-shaped groove 13 on the connecting piece body 1 is placed with the steel clad wood 3, and the screw rod 5 is tightened to clamp and fix it. The combined body is pressed tightly against the steel back rib 2. The positioning support rod 4 on the connecting piece body 1 is inserted into the positioning groove 21 in the steel back rib 2 to position it up and down. After the clamping hook 7 is inserted, a nut 9 is tightened to fix it and then it can be used. This connecting claw connects the steel back rib 2 and the steel clad wood 3 to eliminate the nailing link at the operation site, thereby improving the production and assembly efficiency. Since there is no need for nailing, the damage to the steel clad wood 3 body is also eliminated, and the turnover rate is improved.
[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
