Embodiment Construction
[0049] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0050] Traditional high-speed railway bridge deck shutters8 such as Figure 7 with Figure 8 As shown, in the process of making, the reinforcement cage 13 (such as Figure 5 with Image 6 Shown) placed in the mold, and then filled with concrete to achieve. The reinforcement cage 13 needs to have a part of the steel bars exposed outside, so the reinforcement cage 13 includes an embedded part and an exposed part, and the exposed part is a U-shaped steel bar. More specifically, the reinforcement cage 13 includes a vertical steel bar 13.1, a horizontal fixed steel bar 13.2, a 6-shaped steel bar 13.3 and a longitudinal steel bar 13.4, and the horizontal fixed steel bar 13.2 fixes the vertical steel bar 13.1, the 6-shaped steel bar 13.3 and th...

The invention discloses a high-speed railway bridge floor curtain board non-spacer prefabrication construction device which comprises a welding tool, supports and a mold. The welding tool comprises steel reinforcement cage props, a first beam, a second beam, a fourth beam and a fifth beam. The steel reinforcement cage props comprise the vertical props and the transverse props. The first beam, thesecond beam, the fourth beam and the fifth beam are arranged on the steel reinforcement cage props. The first beam and the second beam are arranged on one side of the steel reinforcement cage props, the fourth beam and the fifth beam are arranged on the other side of the steel reinforcement cage props, and the first beam is provided with limiting pieces. The mold comprises a bottom board, a back board, end boards, a cover board and a baffle, the back board, the left end board and the right end board are hinged to the bottom board; and the cover board is arranged on the end boards, the supportscomprise bottom locating boards and height locating pieces, and the height locating pieces and the bottom locating boards are fixed. By the adoption of the scheme, a large amount of labor force and time can be saved, the quality of curtain boards is good, cost is low, and good economic benefits can be brought.
Description
technical field [0001] The invention relates to a gasket-free prefabricated construction equipment for a high-speed railway bridge deck shield. Background technique [0002] With the rapid development of high-speed railways in my country, the requirements for high-speed railway construction standards are also increasing, especially for high-speed railway bridge deck related accessories, such as the manufacturing process of shutters. The traditional shutter mold uses bolts to connect the various parts, which takes a lot of effort. [0003] Existing molds require prefabricated shrouds with gaskets inside the mould, and the surface of the shrouds produced in this way has indentations of the gaskets, which affects the shape and increases the construction cost due to the use of the shims. [0004] In addition, the preparation of steel cages is also a very difficult task, and operators often spend a lot of time and energy on preparing steel cages. Contents of the invention [...
