Description

Technical Field

[0001] The utility model relates to the field of engineering technology and science, in particular to a linear and reinforcing bar control tool for prefabricated small columns in a track maintenance trench. Background Art

[0002] During the concrete pouring process of the maintenance trench of subway parking lots in my country, the control of the state of the linear and prefabricated small column dowels has become a prominent issue. At present, due to technical or management deficiencies, the state of these dowels often cannot meet the design requirements, resulting in the need for secondary corrections after the pouring is completed. This not only wastes precious time and resources, but also increases construction costs.

[0003] Specifically, the deviation of linear reinforcement may affect the overall stability of the concrete structure, while the inaccuracy of prefabricated small column reinforcement may affect the use function and safety of the maintenance trench. The concrete pouring operation under this state is inefficient and cannot meet the dual requirements of modern subway projects for construction period and quality.

[0004] In addition, the problem of insufficient precision cannot be ignored. In some key parts, such as stress nodes or connections, the precision of the inserted reinforcement is directly related to the overall performance of the structure. However, the current technical means and management measures seem to be unable to fully guarantee this, which undoubtedly brings potential risks to the safety and stability of subway projects.

[0005] Therefore, in order to solve this problem, it is necessary to study and improve the existing construction technology and management measures. In order to ensure the quality of concrete pouring in the subway parking lot maintenance trench, improve work efficiency, reduce construction costs, and meet the high requirements of modern subway projects on quality and construction period, a new technical solution is now needed. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a linear and reinforcing bar control tool for prefabricated small columns in a track maintenance trench, so as to improve the state control and construction accuracy of the linear and prefabricated small column reinforcing bars.

[0007] In order to achieve the above-mentioned purpose, a linear and dowel control tooling for prefabricated small columns in a track maintenance trench is designed. The tooling adopts a modular structure, and two adjacent toolings are connected by bolts so that the connected multiple toolings are on the same horizontal line. Each tooling comprises: two parallel angle steels as positioning rods; one or more positioning steel plates connected to the two angle steels, and a number of dowel positioning sleeves are provided on the positioning steel plates; and a movable clamp connected to the positioning steel plates.

[0008] Preferably, the positioning steel plate has a center hole, and the movable clamp includes a fixed side and a movable side. The fixed side of the movable clamp is connected to the positioning steel plate through the center hole of the positioning steel plate, and one end of the movable side of the movable clamp is sleeved in the fixed side of the movable clamp and connected to the fixed side of the movable clamp through a movable bolt.

[0009] Preferably, the movable fixture fixes the tooling on the outside of the template.

[0010] Preferably, the positioning sleeve is used to insert the prefabricated small column dowel.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. It can effectively control the linearity of the side wall of the maintenance trench to improve the appearance quality and linearity.

[0013] 2. Due to casting problems and other problems, the original prefabricated small column reinforcement will be offset, tilted, and damaged to varying degrees. The use of tooling can improve the state of the small column reinforcement and increase accuracy.

[0014] 3. Can be recycled, saving costs.

[0015] 4. The assembly is simple and is conducive to actual construction on site. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.

[0022] The utility model provides a linear and reinforcing bar control tool for prefabricated small columns in a track maintenance trench.

[0023] The tooling adopts a modular structure, and two adjacent toolings are connected by bolts 1-1 so that the connected multiple toolings are on the same horizontal line.

[0024] Each of the toolings comprises: two angle steels 1-5 arranged in parallel as positioning rods; one or more positioning steel plates 1-3 connected to the two angle steels 1-4, on which the positioning steel plates 1-3 are provided a number of dowel positioning sleeves 1-6; and a movable clamp 1-2 connected to the positioning steel plates 1-3.

[0025] The positioning steel plate 1-3 has a central hole, and the movable clamp 1-2 includes a fixed side and a movable side. The fixed side of the movable clamp 1-2 is connected to the positioning steel plate through the central hole of the positioning steel plate 1-3. One end of the movable side of the movable clamp 1-2 is sleeved in the fixed side of the movable clamp 1-2 and connected to the fixed side of the movable clamp 1-2 through a movable bolt 4-1. The movable clamp 1-2 fixes the tooling outside the template. The positioning sleeve 1-6 is used to insert the prefabricated small column dowel.

[0026] Specifically:

[0027] The utility model is composed of L50*50*5 angle steel 2-3, 3mm thick positioning steel plate 2-2, dowel positioning sleeve 2-1, movable clamp 1-2, and tooling assembly connection bolt 1-1. Figure 1 shown.

[0028] Use two L50*50*5 angle steels 2-3 as positioning rods, place positioning steel plates 2-2 at the left and right ends, the positioning steel plates 2-2 are 3mm thick steel plates, and insert positioning sleeves 2-1 are set above the positioning steel plates 2-2. Figure 2 shown.

[0029] Angle steel 3-3 is used for connection of tooling. Angle steel 3-3 is welded at both ends of positioning steel bar 3-2, and a hole is punched in the center. Bolt 3-1 is used for connection. Figure 3 shown.

[0030] Since the small column fixture cannot be directly fixed on the steel bar, a movable clamp is used to fix it on the outside of the template and tighten it by rotating the bolt 4-1 in the clamp 4-2. Figure 4 shown.

[0031] Finished tooling is prefabricated in the processing plant to facilitate on-site construction needs. The positioning steel plates 1-3, angle steels 1-5 rods, connecting angle steels 1-4, and clamps 1-2 are all the same. The processing length and size of the angle steels 1-5 rods can be determined according to the actual situation on site.

[0032] The prefabricated tooling and other components are transported to the site. Lay out the lines on site to confirm the reference point of the placement position, place the tooling above the maintenance trench, adjust the tooling linearity according to the reference point, adjust the tooling to the same horizontal line, and then use bolts 1-1 to connect the tooling in sequence. Use the movable clamp 1-2 to tighten the tooling. After fixing, put the prefabricated small column dowels into the positioning steel plate sleeve 2-1 and pour concrete.

[0033] After the concrete solidifies, the tooling will be removed and recycled.

[0034] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
