Technical Field

[0001] The utility model belongs to the technical field of road and bridge construction, in particular to an anti-collision wall formwork supporting device. Background Art

[0002] Most highway bridge guardrails are made of NJ reinforced concrete wall, which we call crash barriers. When pouring crash barriers, the maximum displacement of the template after being stressed is 37mm, and the verticality is 7Film, which makes the crash barriers not straight and has a poor appearance, seriously affecting the quality of the project. Therefore, the correct installation of the template is an important part of ensuring the appearance quality of the crash barriers. After searching, the patent with application number 202321705894.5 discloses a crash wall formwork support device, including a cross frame located above the crash wall and perpendicular to the length direction of the crash wall, an inner bracket arranged on the side of the inner mold facing the bridge side plate, and an outer bracket arranged on the outer side of the outer mold, the lower end of the outer bracket is provided with a bottom support part, the upper part of the outer bracket and the part of the cross frame extending outside the crash wall are slidably fixedly connected along a direction perpendicular to the length direction of the crash wall, the outer bracket is pressed against the outer mold and its bottom support part supports the lower edge of the outer mold, the upper end of the inner bracket is detachably fixedly connected to the part of the cross frame located inside the crash wall, the inner bracket is pressed against the inner mold, and the lower edge of the cross frame is detachably fixedly connected to the upper edge of the inner mold.

[0003] However, in actual use, the applicant found that the support and fixation of the inner and outer molds of the anti-collision wall are achieved by setting up multiple structures such as cross frames, upper cross bars, lower cross bars, connecting plates, clamps, screw rods, inner brackets, outer brackets and fasteners, which make the structure of the anti-collision wall template more complicated and not convenient to operate. In view of this, we propose a support device for the anti-collision wall template. Utility Model Content

A fixing seat 13 is bent outwardly at the bottom of the inner formwork 1, and the fixing seat 13 is fixed to the bridge side beam by a locking bolt 14. A second upper column head 41 is symmetrically arranged on the inner wall of the upper part of the outer formwork 4, and a second lower column head 42 is symmetrically arranged on the inner wall of the lower part of the outer formwork 4. One end of the upper hard circular tube 2 is sleeved on the first upper column head 11, and the other end of the upper hard circular tube 2 is sleeved on the second upper column head 41. One end of the lower hard circular tube 3 is sleeved on the first The upper and lower hard circular tubes 2 and 3 are used to support the distance between the inner formwork 1 and the outer formwork 4, and can also facilitate personnel to smoothly and easily remove the upper and lower through-rods 5 and 6 after the anti-collision wall is cast. At the same time, the upper and lower hard circular tubes 2 and 3 are retained in the anti-collision wall, which can also improve the structural strength of the anti-collision wall. One end of the upper and lower through-rods 5 and 6 is provided with a butt joint 9, and the other end of the upper and lower through-rods 5 passes through the inner formwork 1, the upper hard circular tube 2 and the outer formwork 4 in sequence, and the other end of the lower through-rod 6 passes through the inner formwork 1, the lower hard circular tube 3 and the outer formwork 4 in sequence. The other ends of the upper and lower through-rods 5 and 6 are provided with a slot 8, and the outer formwork The outer wall of the seat body 7 is fixedly connected to the seat body 7, and the interior of the seat body 7 is symmetrically and movably provided with a U-shaped movable frame 71, which slides along the guide slide groove provided inside the seat body 7, and the two ends of the U-shaped movable frame 71 extend to the outside of the seat body 7 and are respectively inserted into the clamping grooves 8 provided on the upper through rod 5 and the lower through rod 6. The inner template 1 and the outer template 4 can be locked and fixed by the upper through rod 5 and the lower through rod 6, which is convenient to operate. The two seat bodies 7 are elastically connected by springs 72, and four springs 72 are provided between the two U-shaped movable frames 71. The two ends of the spring 72 are respectively fixedly connected to the two U-shaped movable frames 71, and a toggle handle 711 is fixedly provided in the middle of the U-shaped movable frame 71. The toggle handle 711 extends to the outside of the seat body 7, and the toggle handle 711 can be used to lock the inner template 1 and the outer template 4.
