Description

TECHNICAL FIELD

[0001] The utility model relates to a reinforcing equipment, especially a bridge hinge joint reinforcing equipment. BACKGROUND

[0002] Because of the special requirements of railway operating line, the requirement for preventing bridge broken stone concrete from falling is very strict, and many T beam hinge joints in the present situation of cross-railway bridge are prone to have different degrees of concrete falling problems due to concrete fatigue and other factors, which seriously affect the safety of railway operating line. The bridge that needs to repave the bridge deck leveling layer has incomplete hinge joint treatment, and the hinge joint concrete is more prone to fall during the bridge deck chiseling and the concrete pouring of the bridge deck leveling layer.

[0003] Nowadays, when the hinge joint is treated, 2-4 people on the track maintenance vehicle are used in combination with a ladder to chisel the loose part of the hinge joint, and then polyurethane foam is applied. However, this treatment method is not thorough, the polyurethane foam is prone to aging, has insufficient durability, and the polyurethane is prone to falling during the bridge deck chiseling and the concrete pouring.

[0004] In view of the above problems, we provide a bridge hinge joint reinforcing equipment. CONTENT OF THE UTILITY MODEL

[0025] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0026] This application provides a bridge hinge joint reinforcement device.

[0027] Example 1, such as Figures 1-4 As shown.

[0028] A bridge hinge joint reinforcement device includes several sets of side plates 1, with two side plates 1 in each set. The bottom surfaces of the two side plates 1 in the same set are provided with an arc-shaped base 2, forming a U-shaped structure. Preferably, the width of the two side plates 1 is 8mm, the thickness is 1mm, and the distance between the two side plates 1 in the same set is 6mm. The side plates 1 are made of 201 stainless steel plate. The U-shaped structure formed by the side plates 1 and the arc-shaped base 2 can generate a certain deformation during the expansion and contraction of the bridge, thus preventing damage to the hinge joint reinforcement device.

[0029] A top support plate 3 is detachably connected to the top surface of the side plate 1. The top support plate 3 is preferably 10mm wide and 1mm thick, and is made of 201 stainless steel plate. Several sets of the side plates 1 are placed adjacent to each other in the hinge joint of the bridge, with the top support plate 3 in contact with the beam surface. During installation, after removing the existing concrete leveling layer and hinge joint mortar, the U-shaped structure composed of the side plates 1 and the arc-shaped plate is placed into the hinge joint, while the top support plates 3 on both sides are in contact with the beam surface. The side plates 1 and the arc-shaped bottom 2 effectively isolate the hinge joint, preventing concrete from falling through it.

[0030] An intercepting plate 4 is placed at the gap between two adjacent sets of side plates 1 and arc-shaped bottom 2 to block the gap between adjacent side plates 1 and arc-shaped bottom 2, so as to prevent the inner cavities of several sets of side plates 1 and arc-shaped bottom 2 from becoming one and intercepting the falling concrete.

[0031] The shape of the interceptor plate 4 is adapted to the side plate 1 and the arc-shaped bottom 2. The side plate 1 and the arc-shaped bottom 2 form a U-shaped structure, so the interceptor plate 4 is also a U-shaped structure.

[0032] Limiting strips 5 are provided on both sides of the arc-shaped bottom 2, and the interceptor plate 4 is placed between two adjacent limiting strips 5. The height of the limiting strips 5 is greater than the thickness of the interceptor plate 4. By setting the limiting strips 5, the installation time of the interceptor plate 4 can be greatly shortened. During installation, simply pinch the upper ends of both sides of the interceptor plate 4 so that the bottom of the interceptor plate 4 is between the two limiting strips 5, and then release.

[0033] A filler layer 6 is provided between the two side panels 1. The filler layer 6 is made of polyurethane foam. The filler layer 6 is used to fill the gap between the two side panels 1.

[0034] The side plate 1 has a connecting bent plate 7 on its top surface, and the top support plate 3 has a mating bent plate 8 on its inner side. The connecting bent plate 7 and the mating bent plate 8 are adapted to detachably connect the side plate 1 and the top support plate 3 together. The connecting bent plate 7 has an L-shaped structure. In use, the mating bent plate 8 is inserted into the outside of the connecting bent plate 7 to connect the side plate 1 and the top support plate 3 together.

[0035] When using this utility model:

[0036] 1. Remove the existing concrete leveling layer and hinge mortar.

[0037] 2. According to the hinge joint length, connect several sets of the side plates 1 to the top support plate 3, and then place them into the hinge joint so that the top support plate 3 contacts the beam surface.

[0038] 3. Place the interceptor plate 4 between the two limiting strips 5.

[0039] 4. The filling layer 6 is filled into the gap between the two side plates 1, and the surface of the filling layer 6 is flush with the top support plate 3.
