Description

Technical Field

[0001] The utility model relates to a portable steel bar truss floor deck repair tool, and relates to the technical field of repair tools. Background Art

[0002] The steel truss floor decking is made of a galvanized base plate and a steel truss that are spot welded together using high-frequency resistance welding in the factory. The specification requires that the thickness of the galvanized base plate should not be less than 0.5 mm. Because the role of the galvanized base plate is not considered during the use stage, it only serves as a template during the construction stage. Therefore, general design institutes require the thickness of the galvanized plate to be around 0.5 to 0.8 mm. As a result, the galvanized steel plate is very likely to deform due to external impact, especially during the transportation and construction of the steel truss floor decking, which will inevitably cause bumps, easily leading to deformation of the surface of the steel truss floor decking, and easily affecting the normal use of the steel truss floor decking.

DETAILED DESCRIPTION

[0022] See also Figure 1-5 As shown, the technical solution adopted in this specific embodiment is: it comprises a handle 1, the front end of the handle 1 is a connecting groove 3, a repair splint 2 is arranged in the connecting groove 3, the end of the repair splint 2 away from the handle 1 is an open structure, the open end of the repair splint 2 can be used to clamp the galvanized steel plate, and the arc end can also lift the galvanized steel plate, and the repair splint 2 can be rotated in the connecting groove to achieve adjustment of different height positions, which is convenient for repairing galvanized steel plates with different degrees of deformation;

[0023] Specifically, a rotating shaft 4 is arranged in the connecting groove 3, a rotating sleeve 5 is arranged at the bottom of the repair splint 2, and the rotating sleeve 5 is connected to the rotating shaft 4. Through the cooperation between the rotating sleeve 5 and the rotating shaft 4, the repair splint 2 can be rotated relative to the handle 1.

[0024] The rotating sleeve 5 is provided with a plurality of limit grooves 9, and a positioning rod 8 is provided in the handle 1. The positioning rod 8 matches the limit grooves 9. In order to realize the positioning of the rotating sleeve 5, a movable positioning rod 8 is provided in the handle 1. The positioning rod 8 is moved in the handle 1 to realize the constraint and release with the limit grooves 9, so that the repair splint 2 can be positioned at different angles.

[0025] More specifically, a mounting groove 6 is provided on the handle 1 near the connecting groove 3. The mounting groove 6 is vertically downwardly arranged, and a through groove is horizontally connected to the connecting groove 3. The through groove on the mounting groove is mainly a passing groove for the positioning rod 8, and the positioning rod 8 moves therein.

[0026] To be more specific, a movable plate 7 is provided in the installation groove 6, and the movable plate 7 is connected to the positioning rod 8 on the side of the repair splint 2. A connecting rod 14 is provided on the top of the movable plate 7, and the connecting rod 14 passes through the sliding groove 12, and a pushing block 13 is provided on the top of the connecting rod 14. The pushing block 13 is constrained by the sliding groove 12, and the movement of the positioning rod 8 is achieved by moving the pushing block 13 to drive the movable plate 7 to move.

[0027] More specifically, a positioning groove 10 is provided on the rotating shaft 4, and the size of the positioning groove 10 matches the positioning rod 8. In order to ensure the fixing effect of the positioning rod 8 on the repair splint 2, a positioning groove 10 is provided on the rotating shaft 4. According to the actual usage scenario, the number of the positioning groove 10 is set to at least one, and the positioning rod 8 can continue to be inserted into the positioning groove 10 after being inserted into the limit groove 9 at least at one rotation angle, so that the force on the repair splint is maximized.

[0028] More specifically, a sliding sleeve 11 is disposed on the top surface of the installation groove 6 , and a sliding groove 12 is disposed inside the sliding sleeve 11 . The sliding groove 12 mainly cooperates with the pushing block 13 to constrain the travel of the pushing block 13 .

[0029] More specifically, the mounting groove 6 is provided with a mounting sleeve 15 on the side away from the repair splint 2 in the axial direction, and the movable plate 7 is provided with a fixing sleeve 16 on the side away from the repair splint 2. The mounting sleeve 15 is sleeved with a spring.

[0030] 17, the other end of the spring 17 is embedded in the fixed sleeve 16, the mounting sleeve 15 is provided with a positioning sleeve 19, the movable plate 7 is provided with a positioning slide bar 18 without the fixed sleeve 16, the positioning slide bar 18 is embedded with the positioning sleeve 19, the mounting sleeve 15 and the fixed sleeve 16 are used to constrain and position the spring 17 to ensure the restoring effect of the spring 17, the cooperation between the positioning sleeve and the positioning slide bar 18 ensures that the movable plate 7 will not get stuck when moving, and the spring 17 can be more ready to complete the reset of the positioning rod 8 and fix the repair splint 2.

[0031] When the workpiece 2 is in the working state, the movable plate 7 is moved to the position where the spring 17 is engaged, and the positioning rod 8 is pushed toward one side of the repairing splint 2. The positioning rod 8 passes through the through slot on the handle 1 and is inserted into the limiting slot 9 on the rotating sleeve 5 and the positioning slot 10 on the rotating shaft 4, so that the repairing splint 2 is in a fixed angle position. Usually, the repairing splint 2 and the handle 1 are kept in a horizontal state for easy carrying. When the repairing operation is needed, according to the degree of deformation, the pushing block 13 is first moved to drive the movable plate 7 to compress the spring 17, so that the positioning rod 8 withdraws from the limiting slot 9 and the positioning slot 10. At this time, the repairing splint 2 can be rotated by the cooperation of the rotating sleeve 5 and the rotating shaft 4. After adjusting to the appropriate position, the pushing block 13 is released, so that the movable plate 7 drives the positioning rod to be inserted into the limiting slot 9 and the positioning slot 10 again, completing the position adjustment of the repairing splint 2, and putting the galvanized steel plate into the hollow position inside the repairing splint 2. By raising the position of the repairing splint 2, it is convenient to correct the deformed position.
