Description

Technical Field

[0002] When constructing a bridge anti-collision guardrail, in order to prevent the appearance of shrinkage cracks in the anti-collision guardrail, true joints with a width of 20 mm need to be left on the guardrail. In the prior art, a combined component of a 10-mm-thick bamboo plywood and a 10-mm-thick rigid foam board is mostly used as the joint filling material. The rigidity of the bamboo plywood is used to ensure no deformation during the pouring process, and the brittleness of the rigid foam board is convenient for later removal. Although using bamboo plywood in combination with rigid foam board overcomes the disadvantages of using bamboo plywood or rigid foam board alone and ensures the true joint width and straight alignment to a certain extent, it is easy to damage the structural surface during the later chiseling process, resulting in poor appearance quality, damaged true joint edges and corners, unaesthetic appearance, cumbersome processes and waste of materials;

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Refer to Figures 1-3, A construction tool for the true joint of a bridge anti-collision guardrail, which includes two anti-collision guardrail templates 1. There is a true joint between the two anti-collision guardrail templates 1, and a sandwich steel plate assembly 2 is inserted through the true joint. The sandwich steel plate assembly 2 is composed of a first steel plate 201, a second steel plate 202 and a third steel plate 203 that are close to and fit together. The third steel plate 203 is in the middle of the first steel plate 201 and the second steel plate 202. The top surfaces of the first steel plate 201, the second steel plate 202 and the third steel plate 203 are all higher than the top surface of the anti-collision guardrail template 1. A plurality of mounting holes 3 are correspondingly opened at the edges of the anti-collision guardrail template 1, the first steel plate 201, the second steel plate 202 and the third steel plate 203, and bolts 4 are installed through the mounting holes 3 for fixation. Hoisting holes 5 are opened at both sides of the top of the first steel plate 201, the second steel plate 202 and the third steel plate 203;

[0022] For the technical solution adopted above, by bringing the three steel plates close to and fitting together, placing them at the true joint of the guardrail, and connecting them to the anti-collision guardrail template 1 as a whole through bolts 4. When the formwork is removed after the guardrail is poured, by first removing the middle steel plate and then removing the other two steel plates, the purpose of reserving a broken joint is achieved. This construction method can make the true joint straight and standard, with a beautiful appearance, truly preventing the appearance of shrinkage cracks in the anti-collision guardrail concrete, ensuring the quality of the project entity, and the device has a simple structure, is convenient and practical, easy to disassemble and assemble, and has high use efficiency;

[0023] It should be noted that the aperture of the mounting hole 3 is slightly larger than the aperture of the bolt 4 to ensure convenient through-tightening and disassembly of the screw rod. The sandwich steel plate assembly 2 is installed at the true joint and is connected to the anti-collision guardrail template 1 as a whole through bolts 4 to prevent displacement and deformation.

[0024] The top surfaces of the first steel plate 201, the second steel plate 202 and the third steel plate 203 are respectively 10 cm, 20 cm and 30 cm higher than the top surface of the anti-collision guardrail template 1;

[0025] For the technical solution adopted above, by setting the heights of the three steel plates to different sizes and all higher than the top surface of the anti-collision guardrail template 1, it is convenient to hoist and extract the steel plates in sequence.

[0026] Lubricating oil is applied to both surfaces of the first steel plate 201, the second steel plate 202 and the third steel plate 203;

[0027] For the technical solution adopted above, by applying lubricating oil to both sides of the steel plate, the friction can be reduced, thus facilitating its subsequent disassembly and extraction.

[0028] Working principle:

[0029] At the true joint, a sandwich steel plate assembly 2 is formed by three steel plates approaching and fitting together. Before construction, the sandwich steel plate assembly 2 is placed at the position where the true joint needs to be set, and the sandwich steel plate assembly 2 is connected to the anti-collision guardrail formwork 1 as a whole through bolts 4. After construction, when the formwork is removed, a trolley is used to stretch and take out the third steel plate 203 with lubricant coated on both sides in the sandwich steel plate assembly 2. After that, the first steel plate 201 and the second steel plate 202 can be easily taken out from the true joint. The true joint of the guardrail constructed by this construction method does not need to be grooved, has a good forming effect, saves the working hours of true joint construction, and improves the efficiency of true joint construction.
