Description

Bridge anticollision barrier preparation mould Technical Field The utility model belongs to the technical field of building equipment, and particularly relates to a manufacturing die for a bridge anti-collision guardrail. Background In carrying out the utility model, the inventors have found that the prior art has at least the following problems: At present, the bridge engineering crash barriers in the building industry are all designed to be SA-level/SAm-level F-type wall barriers, the structural form is narrow in the upper part and wide in the lower part, and the contours on two sides are provided with rounding angles. The mature construction methods of the crash barrier at present are divided into two types of off-site prefabrication and on-site cast-in-place, wherein the construction process comprises on-site reinforcement bar binding, inner and outer side template assembly and concrete pouring. The conventional construction of the bridge anti-collision guardrail has the following defects: (1) The structure forms with narrow upper part and wide lower part show that the vibrating bars cannot be smoothly inserted into two sides of the bottom in the concrete pouring process, so that concrete vibration at two sides of the bottom cannot be effectively completed, the appearance quality of a structure is low after the mold is removed, and quality common problems such as bubbles, holes and the like often occur; (2) Due to the limitations of the head space, in the vibrating process of the vibrating rod it is impossible to avoid the collision with the reinforcing bars, the steel bar is extruded and deformed, and the qualification rate of the protective layer of the structural finished product is seriously affected; (3) The unified back field processing preparation of bridge anticollision barrier reinforcing bar, on-the-spot ligature shaping, the ligature in-process receives precast beam top surface elevation influence, and template in-process bottom chamfer can have the position deviation, can't accurate corresponding the assembling with template chamfer position, and construction is meticulous to require highly, and the construction work management and control degree of difficulty is big. (4) In the cast-in-situ process of the bridge anti-collision guardrail, the expansion and contraction of the structure are considered, and the intermittent fracture is arranged, wherein the intermittent fracture comprises true joint and false seams. True joint is generally divided by adopting a 3-5 mm thick wood plate, but the template is thinner, deformation is easy to occur due to extrusion in the concrete pouring process, so that the vertical linear deviation of the side surface is larger, the false joint is generally mechanically cut after the template is removed, and the construction refinement requirements of quality control items such as the gap depth, the linear shape and the like are high. And no matter true joint or false seams, the quality problems such as structural cracking, breakage and the like are very easy to occur at two sides of the broken seam in the construction process. CN 214832000U-a bridge engineering spandrel post cement mortar fills mould, discloses a bridge engineering spandrel post cement mortar fills mould, including first mould, second mould, splicing mechanism includes the fixture block of articulated on first mould lateral wall, sets up the draw-in groove on the second mould lateral wall, sets up the spacing groove at first mould top, fixes the sealing washer on spacing groove inner wall, also can't solve above-mentioned technical problem. Disclosure of utility model The utility model aims to solve the technical problem of providing a bridge anti-collision guardrail manufacturing die, which eliminates the structural limitation of narrow upper part and wide lower part of guardrails in the old construction process, is convenient for concrete vibration and effectively controls the quality of the anti-collision guardrail. In order to solve the technical problems, the utility model adopts the technical scheme that the manufacturing die for the bridge anti-collision guardrail comprises the following components: a bottom die transverse rib; Side panels arranged on two sides of the bottom die transverse rib; The bottom die transverse rib, the side panels and the end panels are enclosed to form a box body, and concrete can be poured in the box body; The upper transverse rib is arranged at the upper end of the side panel, and a hanging hole positioning die is arranged on the upper transverse rib; and the turnover mechanism is arranged on the side panel.
