For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0022] The present application will be further elaborated in detail below with reference to the drawings and embodiments.
[0023] Referring to Figures 1 to 4 , an H-shaped steel fixed caliper is provided in an embodiment of the present application, including an H-shaped steel 1. Square timbers 3 are arranged on both the front and rear sides of the H-shaped steel 1. Two sleeper timbers 4 are arranged at the bottoms of the two square timbers 3. A caliper assembly 2 is arranged between the two square timbers 3. The caliper assembly 2 includes a main body steel pipe 21. A steel plate 26 is fixedly installed on the outer side of the front end of the main body steel pipe 21. A connecting steel pipe 22 is fixedly installed on the outer side of the rear end of the main body steel pipe 21. A threaded sleeve 23 is fixedly installed on the outer side of the connecting steel pipe 22. A screw rod 24 is screwed inside the threaded sleeve 23. A steel bar 25 is fixedly installed at the outer end of the screw rod 24. The steel plate 26 is located on the back of the rear square timber 3, and the inner end of the screw rod 24 is located in front of the front square timber 3.
[0024] The two sleeper timbers 4 are respectively located on the left and right sides of the H-shaped steel 1, and the sleeper timbers 4 are embedded in the ground. The main body steel pipe 21 and the steel plate 26 are fixedly connected by welding. The main body steel pipe 21 and the connecting steel pipe 22, the connecting steel pipe 22 and the threaded sleeve 23, and the screw rod 24 and the steel bar 25 are all fixedly connected by welding. The length of the main body steel pipe 21 is 25 cm, the diameter is 22 mm, and the wall thickness is 3 mm. The length of the connecting steel pipe 22 is 3 cm, and the wall thickness and diameter of the connecting steel pipe 22 are the same as those of the main body steel pipe 21. The length of the threaded sleeve 23 is 3 cm. The two ends of the threaded sleeve 23 are aligned with the two ends of the connecting steel pipe 22, and the outer end of the threaded sleeve 23 is aligned with the outer end of the main body steel pipe 21. The steel bar 25 is an equilateral triangle with a side length of 5 cm, and one corner of the steel bar 25 is welded to the outer side of the main body steel pipe 21.
[0025] In this embodiment, the first step: material cutting. The thin-walled steel pipe is cut into short sections with a length of 25 cm, the steel plate is cut into an equilateral triangle shape with a side length of 5 cm, the length of the screw rod is cut into 12 cm, and the threaded sleeve is 3 cm.
[0026] Step 2: Welding and forming. After the materials are cut, successively weld and shape the steel plate 26, the main steel pipe 21, the connecting steel pipe 22, and the threaded sleeve 23. Then weld a steel bar 25 to one end of the screw rod 24 as a rotating operating rod. After the reinforcement is completed, rotate the screw rod 24 into the threaded sleeve 23.
[0027] During the construction process, after the H-shaped steel is adjusted, the square timber 3 is reinforced by rotating the operating rod of the screw rod 24, indirectly achieving the effect of fixing the H-shaped steel.
[0028] The cheapest steel calipers purchased in the market cost 25 riyals each, are easily damaged, and it is difficult to clean the concrete after pouring, resulting in a low recycling rate. Self-made caliper device: The production cost is about 6 riyals each, is strong and durable, and has the same reinforcement effect as the purchased calipers.
[0029] After construction verification, using the self-made caliper device greatly saves costs and improves project efficiency. At the same time, the self-made caliper is simple to manufacture, convenient to operate, and the single cost is reduced by 19 riyals (equivalent to 37 yuan in RMB) compared with the purchased calipers, with significant economic benefits.
