Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a top wall bolt mounting frame for construction engineering. Background Art

[0002] Expansion bolts are a special type of threaded connector that utilizes the shear slope to promote expansion and generate frictional gripping force, thereby achieving a fixing effect. Currently, in the construction of building decoration ceilings and electromechanical installation, there are a large number of operations that require the use of expansion bolts to fix hangers and hangers on the roof slab. According to traditional operation methods, mobile scaffolding is required for the installation of roof expansion bolts. The installation of ceiling expansion bolts requires workers to tighten them on the construction frame with a wrench. During the construction process, workers need to repeatedly climb and move scaffolding, which not only poses a safety hazard to high-altitude operations, but also is difficult to operate, with a large workload and high cost, and also reduces construction efficiency. Utility Model Content

[0006] The beneficial effects of the utility model are:

[0007] During the installation process of the mounting piece, the fitting sleeve is in close contact with the mounting surface, thereby increasing the friction force of the fitting sleeve on the mounting surface, thereby improving the stability of the mounting piece during the installation process.

[0008] The lower end of the mounting piece can be adjusted up and down. The fast adjustment between the fixed tube and the sliding rod can be achieved by inserting the rod, and the slow adjustment between the positioning sleeve and the sliding rod can be achieved by adjusting the nut. This allows the fitting effect between the fitting sleeve and the mounting surface to be maintained while maintaining the adjustment speed. This is suitable for top wall installation work at different heights. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] This program has the following working process:

[0022] During the preparation work, the lower end surface of the support base 10 is brought into contact with the ground, and the mounting member 14 to be installed is placed in the support sleeve 21. Then, the top plate 25 is inserted from top to bottom at the clamping plate 22 on the sliding rod 12, so that the lower end of the top plate 25 is clamped with the clamping plate 22. The top plate 25 is provided with a fitting sleeve 13 that can slide up and down.

[0023] During installation, the user pulls the plug rod 17 to make the plug rod 17 overcome the thrust of the spring at the connection with the sliding sleeve 19 and slide to the left, so that the plug rod 17 is disengaged from the slot 20 at the positioning sleeve 23, and then the plug rod 17 slides upward along the direction of the slide groove 18 under the abutment between the plug rod 17 and the sliding rod 12, so that the sliding rod 12 is pushed upward by the plug rod 17, so that the mounting piece 14 and the fitting sleeve 13 at the upper end of the sliding rod 12 can be inserted into the mounting hole and abut the mounting surface. After preliminary adjustment, the user releases the plug rod 17, and the plug rod 17 is reinserted into the slot 20 under the action of the spring force and abuts against it. Then, the user controls the rotation of the adjusting nut 16 to adjust the adjusting nut 16. The positioning sleeve 23 connected by the inner thread moves up and down, thereby adjusting the upper and lower positions of the positioning sleeve 23 and the sliding rod 12, and then supporting the top plate 25 and the fitting sleeve 13, so that the top plate 25 and the fitting sleeve 13 are partially adjusted up and down, so that the fitting sleeve 13 abuts against the mounting surface, and the fitting sleeve 13 overcomes the spring force of the top plate 25 and slides downward, so that the fitting sleeve 13 is close to the mounting surface. After keeping stable, the user starts the pushing mechanism 24 in the sliding rod 12, so that the power motor at the pushing mechanism 24 works, drives the upper end of the threaded sleeve to rotate, so that the threaded push rod slides upward, pushes the mounting member 14 upward, and inserts the mounting member 14 into the mounting hole, and expands the mounting member 14 through the upper end of the push rod;

[0024] Similarly, the fixed tube 11 and the sliding rod 12 can be arranged in multiple layers. By increasing the number of the insertion rods 17, the range of the rising height of the sliding rod 12 can be increased while the user can still hold the insertion rod 17. For example, the user holds the insertion rod 17 at the uppermost end, so that the insertion rod 17 drives the sliding rod 12 to move upward, and then the user holds the insertion rod 17 at the next end, so that the insertion rod 17 drives the sliding rod 12 on the outer side to move upward, and the adjustment is made step by step.
