Description

Technical Field

[0001] This utility model relates to the field of steel side formwork technology, specifically a steel side formwork structure for concrete pavement construction. Background Technology

[0002] Steel side formwork for concrete pavement construction is a high-strength steel boundary template used for road concrete pouring and forming. Its core function is to accurately define the concrete boundary, maintain the design thickness and alignment during pavement construction, and withstand the lateral pressure during pouring. To ensure that the steel side formwork for concrete pavement construction does not tip over, it is often equipped with a rotatable tripod.

[0003] However, existing steel side formwork is supported by a rotatable tripod. But because the tripod is housed inside the steel side formwork, there is a height difference between the bottom of the tripod and the bottom of the steel side formwork, which causes the steel side formwork to tilt during actual use. Therefore, it does not meet the current requirements. To address this, we propose a steel side formwork structure for concrete pavement construction. Utility Model Content

[0004] The purpose of this utility model is to provide a steel side formwork structure for concrete pavement construction, in order to solve the problem mentioned in the background art that the steel side formwork is supported by a rotatable tripod. However, the tripod of the existing steel side formwork is housed inside the steel side formwork, resulting in a height difference between the bottom of the tripod and the bottom of the steel side formwork, which causes the steel side formwork to tilt during actual use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel side formwork structure for concrete pavement construction, comprising a steel side formwork body, wherein the upper surface of the steel side formwork body is provided with a plurality of positioning holes arranged in a linear array, and the bottom of the steel side formwork body is provided with a plurality of receiving slots arranged in a linear array along the length direction of the steel side formwork body, wherein the positioning holes and the receiving slots are not on the same straight line, and a rotating support frame is rotatably installed on the inner side of the steel side formwork body, wherein the bottom end of the rotating support frame is kept flat with the bottom surface of the steel side formwork body.

[0006] Preferably, a rotating sleeve is fixed to the top of the rotating support frame, and an I-beam positioning sleeve is rotatably installed on the inner side of the rotating sleeve.

[0007] Preferably, a fastening screw is inserted inside the positioning hole, and a fastening bolt is installed above the positioning hole. The fastening screw passes through the I-shaped positioning sleeve and is connected to the fastening bolt by threads.

[0008] Preferably, the bottom end of the rotating support frame is bent downwards and remains vertically downwards, and a guide sleeve is fixed to the outer side of the bottom end of the rotating support frame.

[0009] Preferably, a reinforced tapered rod is slidably inserted inside the guide sleeve, and a separation handle is fixed to the top of the reinforced tapered rod.

[0010] Preferably, the separating handle has a rectangular structure and is hollow in the middle, and the separating handle and the reinforced plug-in tapered rod are integrally cast.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention involves placing the bottom of the steel side formwork body in contact with the ground and rotating the rotating support frame housed inside the steel side formwork body. The bottom end of the rotating support frame is then disengaged from the storage slot until the vertical rotating support frame and the steel side formwork body form a T-shaped structure. This allows the rotating support frame to support the steel side formwork body, thereby ensuring that the steel side formwork body remains perpendicular to the ground during use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figures 1 to 3As shown, a steel side formwork structure for concrete pavement construction includes a steel side formwork body 1. Multiple positioning holes 7 are linearly arrayed on the upper surface of the steel side formwork body 1. Multiple receiving slots 11 are linearly arrayed along the length of the steel side formwork body 1 at its bottom. The positioning holes 7 and the receiving slots 11 are not on the same straight line. A rotating support frame 3 is rotatably installed on the inner side of the steel side formwork body 1. The bottom end of the rotating support frame 3 is flush with the bottom surface of the steel side formwork body 1. The rotating support frame 3, with its bottom flush with the bottom surface of the steel side formwork body 1, supports the steel side formwork body 1, ensuring that the steel side formwork body 1 remains perpendicular to the ground during use. The presence of the receiving slots 11 allows the rotating support frame 3 to be smoothly stored inside the steel side formwork body 1.

[0019] The rotating support frame 3 is fixed with a rotating sleeve 2 at its top. An I-shaped positioning sleeve 8 is rotatably installed on the inner side of the rotating sleeve 2. A fastening screw 9 is inserted through the inner side of the positioning hole 7. A fastening bolt 10 is installed above the positioning hole 7. The fastening screw 9 passes through the I-shaped positioning sleeve 8 and is connected to the fastening bolt 10 by threads. The rotating sleeve 2 at the top of the rotating support frame 3 is fixed in position by the fastening screw 9, the fastening bolt 10 and the I-shaped positioning sleeve 8, and the rotating support frame 3 and the rotating sleeve 2 can rotate around the I-shaped positioning sleeve 8, so as to ensure that the rotating support frame 3 can be easily stored or taken out.

[0020] The bottom end of the rotating support frame 3 is bent downward and kept vertically downward. A guide sleeve 4 is fixed on the outer side of the bottom end of the rotating support frame 3. A reinforcing plug-in tapered rod 5 is slidably inserted inside the guide sleeve 4. A separation handle 6 is fixed on the top of the reinforcing plug-in tapered rod 5.

[0021] The separation handle 6 has a rectangular structure and is hollow in the middle. The separation handle 6 and the reinforcing plug-in tapered rod 5 are integrally cast. The reinforcing plug-in tapered rod 5 is inserted into the ground to fix the bottom end of the rotating support frame 3, thereby ensuring that the rotating support frame 3 will not easily move during use, thus ensuring the stability of the steel side template body 1 during use.

[0022] When constructing a concrete pavement, the steel side formwork body 1 is first installed at the edge of the concrete pavement. During installation, the bottom of the steel side formwork body 1 is brought into contact with the ground, and the rotating support frame 3 housed inside the steel side formwork body 1 is rotated. The bottom end of the rotating support frame 3 is disengaged from the inside of the receiving slot 11. At this time, the rotating support frame 3 drives the rotating sleeve 2 to rotate outside the I-beam positioning sleeve 8 until the vertical rotating support frame 3 and the steel side formwork body 1 form a T-shaped structure. Subsequently, the staff inserted the bottom end of the reinforcing tapered rod 5 into the inside of the guide sleeve 4, and pressed the separation handle 6 at the top of the reinforcing tapered rod 5 downwards, so that the bottom end of the reinforcing tapered rod 5 was inserted into the ground until the separation handle 6 contacted the guide sleeve 4. The operation was repeated until all the rotating support frames 3 were fixed to the ground. The rotating support frames 3, whose bottoms were flush with the bottom surface of the steel side template body 1, supported the steel side template body 1, thereby ensuring that the steel side template body 1 remained perpendicular to the ground during use.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
