Description

Technical Field

[0001] This utility model belongs to the field of concrete frame structure construction technology, and in particular provides a support for removing waste nails on formwork. Background Technology

[0002] When constructing a concrete frame structure, the common method for removing discarded nails from the reused formwork is to use pliers and a small hammer. This method has two drawbacks: first, it takes a long time and requires a lot of manpower, resulting in high construction costs; second, removing discarded nails at close range can easily cause bumps and injuries, posing a significant safety hazard. Utility Model Content

[0003] The purpose of this utility model is to provide a support for removing discarded nails on templates, which solves the problem of removing nails with pliers and small hammers at close range, saves manpower, reduces personal injury caused by collisions, and lowers safety hazards.

[0004] This invention places the puller bracket on the template, then rotates the operating handle to slide and roll, so that the waste nail on the template is embedded in the notch on the puller and the head of the waste nail is stuck in the notch. Then, the handle is pressed down to make the puller lift upward with force, and the waste nail is pulled out of the template by the upward force. Due to the lever principle, it is easier to pull out the waste nail from a distance with the operating handle.

[0005] This utility model includes a base rod 1, a vertical rod 2, a lifting blade 3, a pry bar 4, a roller 5, a sliding roller 6, and a handle 7, which are used in combination. The sliding roller 6 and the roller 5 form a rolling system, and the sliding roller 6 can rotate around the roller 5. The lower ends of the two vertical rods 2 are respectively welded perpendicularly to one end of the two base rods 1. The upper ends of the two vertical rods 2 are respectively welded perpendicularly to both ends of the roller 5. The lifting blade 3 is welded to one end of the pry bar 4, and the angle between the lifting blade 3 and the pry bar 4 is 120°. The other end of the pry bar 4 is welded perpendicularly to one side of the sliding roller 6. The handle 7 is welded perpendicularly to the other side of the sliding roller 6, and the handle 7 and the pry bar 4 are on the same straight line. Figure 1 , Figure 2 ).

[0006] The base rod 1 is made of 40mm thick steel plate and has the following dimensions (length). Width) 300 60mm; Post 2 is machined from a 20mm diameter round tube and is 200mm long; Cutter 3 is machined from a 14mm thick steel plate and its dimensions are (length) Width) 50 30mm, start with a beveled edge at the bottom of the third cut and create a notch in the middle, notch dimensions (length) Width) 10 4mm; the pry bar 4 is made of 14mm thick steel plate, and its dimensions are (length) 150mm wide; 5 rollers are made of 20mm diameter round steel and are 150mm long; 6 is a purchased finished bearing with an outer diameter of 50mm and an inner diameter of 20mm; 7 handles are made of 20mm diameter round steel and are 1000mm long.

[0007] In use, place the puller bracket on the template 8, then operate the handle 7 to rotate the sliding roller 6, causing the scrap nail 9 on the template 8 to embed into the notch on the puller 3 and the scrap nail head to be stuck in the notch. Then press down the handle 7 to make the puller 3 tilt upwards with force. The scrap nail 9 is pulled out of the template 8 by the upward force. Due to the lever principle, it is easier to pull the scrap nail 9 from a distance by operating the handle 7. Figure 3 , Figure 4 ).

[0008] The advantages of this utility model are that it is easy to assemble, easy to operate, simple and practical, solves the problem of using pliers and small hammers to pull things out at close range, saves manpower, and also reduces personal injury caused by collisions and lowers safety hazards.

[0014] Figures 1-4 This is one specific embodiment of the present invention. The present invention will be further described below with reference to the accompanying drawings.

[0015] This utility model includes a base rod 1, a vertical rod 2, a lifting knife 3, a pry bar 4, a roller 5, a sliding roller 6, and a handle 7. When used together, the sliding roller 6 and the roller 5 form a rolling system, and the sliding roller 6 can rotate around the roller 5. The lower ends of the two vertical rods 2 are respectively welded perpendicularly to one end of the two base rods 1. The upper ends of the two vertical rods 2 are respectively welded perpendicularly to both ends of the roller 5. The lifting knife 3 is welded to one end of the pry bar 4, and the angle between the lifting knife 3 and the pry bar 4 is 120°. The other end of the pry bar 4 is welded perpendicularly to one side of the sliding roller 6. The handle 7 is welded perpendicularly to the other side of the sliding roller 6, and the handle 7 and the pry bar 4 are on the same straight line.

[0016] When in use, place the puller bracket on the template 8, then operate the handle 7 to rotate the sliding roller 6, so that the waste nail 9 on the template 8 is embedded in the notch on the puller 3 and the waste nail head is stuck in the notch. Then press down the handle 7 to make the puller 3 tilt upward with force. The waste nail 9 is pulled out from the template 8 by the upward force. Due to the lever principle, it is easier to pull the waste nail 9 from a distance by operating the handle 7.

[0017] During the construction of reinforced concrete frame structures, a pulling bracket was used to remove discarded nails from reused formwork, achieving good results. This pulling bracket is used in combination, with a sliding roller and a shaft forming a rolling system. The sliding roller can rotate around the shaft. The lower ends of two uprights are welded perpendicularly to one end of each of the two base rods; the upper ends of the two uprights are welded perpendicularly to both ends of the shaft; the lifting blade is welded to one end of a pry bar, with a 120° angle between them; the other end of the pry bar is welded perpendicularly to one side of the sliding roller; the handle is welded perpendicularly to the other side of the sliding roller, and the handle and pry bar are aligned. In use, the pulling bracket is placed on the formwork, then the handle is operated to rotate the sliding roller, causing the discarded nail on the formwork to embed into the notch on the lifting blade and lock the nail head in the notch. Then, the handle is pressed down, causing the lifting blade to tilt upwards with force. The discarded nail is pulled out of the formwork by the upward force. Due to the lever principle, it is easier to pull out discarded nails from a distance using the handle. This puller bracket is simple to assemble, easy to operate, and practical. It solves the problem of pulling with pliers and small hammers at close range, saves manpower, reduces personal injury caused by bumps and collisions, and lowers safety hazards.
