Description

Technical Field

[0001] This utility model relates to an installation tool for installing expansion bolts on the suspended rods of a building structure roof, especially for the installation and fixing of suspended rods for ceiling projects in decoration and renovation projects, as well as for air conditioners, air ducts, water pipes, cable trays, etc. on the suspended rods of the structural roof. Background Technology

[0002] In building construction, the installation of ceiling systems and the installation of air conditioning, ductwork, water pipes, cable trays, etc., between the structural roof slab and the ceiling often involves the subsequent installation of suspension rods on the structural roof slab. This subsequent installation of suspension rods often presents challenges such as high working surfaces, the need to protect finished products on the construction site, the intersection of different specifications of suspension rods from different sub-projects, and high requirements for the plumbness of the suspension rods.

[0003] In the construction of existing structural roof slab hanging rods, it is common to set up mobile scaffolding on the ground and have workers use wrenches to tighten the expansion bolts.

[0004] Because the working surface of the top slab structure is high and it is impossible to pre-embed a large number of components, it is often inconvenient for personnel to hang high and use low and to use safety belts properly when moving scaffolding, thus posing a risk of falling from height. Repeated movement of scaffolding can also easily damage the finished floor of the completed ground works, affecting the quality of the project. The installation of different specifications of hangers in different sub-projects often leads to cross-operations and affects work efficiency. The large upward angle of workers leads to a high rate of poor hanger plumbness. Utility Model Content

[0005] To overcome the problems of scaffolding erection, safety belt use, rod tilting and offset, and low efficiency caused by cross-operation of different specifications of rods in the process of manually installing expansion bolts for structural roof slab suspension members, this utility model provides an installation tool. Personnel place the expansion bolt on the top of the tool on the ground and adjust, correct, install and fix the expansion bolt part of the structural roof slab suspension member by manually or electrically turning the installation tool.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a tool for installing expansion bolts on the hanging rods of a structural top plate, including a main working rod and an extension rod. The main working rod has a top nut sleeve, a bolt straightening disc, a movable threaded end of the straightening disc, a main working rod flange, and a flange fixing bolt pair. The extension rod has an extension rod flange, a manual tightening disc, and a bottom bolt head.

[0007] The aforementioned structural top plate hanging rod inverted expansion bolt tool has the same diameter and material for the main working rod and the extension rod. The nut sleeve at the top of the main working rod is welded firmly to the main working rod. The outer diameter of the nut sleeve is threaded to serve as the movable thread of the straightening disc. The inner thread of the bolt straightening disc is threaded to connect with the threaded thread at the top of the main working rod. The flange of the main working rod is welded firmly to the main working rod. The flange of the main working rod and the flange of the extension rod are connected with a suitable bolt pair. The flange of the main working rod and the flange of the extension rod have the same diameter and material to ensure stable and consistent torque transmission during coaxial rotation.

[0008] The above-mentioned structural top plate hanging rods are equipped with inverted expansion bolt tools. The top of the extension rod is welded to the extension rod flange, the extension rod flange is connected to the main working rod flange with a suitable bolt pair, the bottom of the extension rod is welded to the manual screw-on disc, and the extension rod is welded to the bottom bolt head.

[0009] The aforementioned structural top plate hanging rod inverted expansion bolt tool has a through opening at the bottom of the main working rod and the top of the extension rod with the same diameter. The flange of the main working rod and the flange of the extension rod have the same opening diameter and are connected by bolt pairs.

[0010] The beneficial effects of this utility model are that it allows workers to complete the installation of the hanging rods on the ground as much as possible, avoiding working at heights, effectively avoiding the use of scaffolding and safety belts, effectively correcting the plumbness of the hanging rods, avoiding the problems of low construction efficiency and high difficulty caused by cross-operation between hanging rods of different specifications, and directly protecting the finished floor.

[0018] The tool for installing expansion bolts on structural roof slab suspension rods includes selecting a suitable main working rod 1 and extension rod 7 before installing the suspension rods. A suitable flange fixing bolt pair 6 is used to connect and fix the main working rod flange 5 and extension rod flange 8. This design and method facilitates disassembly, assembly, and transport of the expansion bolt tool, while also enhancing the stability and consistency of torque transmission during rotation. After the expansion bolt tool is assembled, the bolt straightening disc 3 is tightened along the movable thread 4 of the straightening disc at the top of the main working rod 1. The suspension rod to be installed, equipped with an expansion bolt, is inserted into the main working rod 1. The expansion bolt nut is engaged with the top nut sleeve 2, and the expansion bolt nut washer is secured to the top of the main working rod 1. Adjust the bolt straightening disc 3 until it is in contact with the expansion bolt nut washer. The bolt straightening disc 3 can overcome the insufficient correction of the expansion bolt nut washer for the expansion bolt caused by the large diameter of the hole in the top plate for embedding the expansion bolt, and it can also overcome the defect of the expansion bolt nut washer for the small leveling range of the rough top plate, which also leads to the deviation. The bolt straightening disc 3 is a necessary supplement to the deviation correction of the expansion bolt with its own nut washer on the longer hanging rod. At the same time, the bolt straightening disc 3 can also make up for the deviation correction defect of the expansion bolt without nut washer. The extension rod 7 is equipped with a manual tightening disc 9, which allows the operator to manually tighten the expansion bolt of the hanging rod to fasten and install the hanging rod. The bottom bolt head 10 is provided at the bottom of the extension rod for the operator to use a power wrench and socket for power tool operation.
