Technical Field

[0001] This utility model relates to the technical field of bottom leveling block molds for crash barriers, specifically a bottom leveling block mold for prefabricated crash barriers for bridge slabs. Background Technology

[0002] During the construction of crash barriers on both sides of the viaduct, a layer of concrete base layer needs to be poured at the installation location of the crash barriers, and the base layer should be set at the same elevation. This ensures that the crash barriers installed on the base layer also have the same elevation, thus making the crash barriers sturdy and aesthetically pleasing. In order to ensure that the base layer is at the same elevation, during the construction of the base layer, since the outer side of the bridge deck is slightly higher in the lateral direction and not level in the longitudinal direction, it is necessary to set up a mold with height adjustment function. Utility Model Content

[0003] The purpose of this utility model is to provide a bottom leveling block mold for prefabricated anti-collision railings for bridge decks, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bottom leveling block mold for a prefabricated bridge crash barrier. The main body of the leveling block mold is a frame, which is formed by a front crossbeam, a rear crossbeam, a left longitudinal beam, and a right longitudinal beam. The front and rear crossbeams are vertical, while the left and right longitudinal beams are horizontal. The inner sides of the left and right longitudinal beams are respectively provided with a left slot and a right slot along the length direction. A left insert is provided in the left slot, and a right insert is provided in the right slot. Both the left and right inserts are provided with an adjustment structure to adjust the height of the insert extending out of the longitudinal beam.

[0005] Preferably, the adjustment structure includes an adjustment lug located on the insert block, the adjustment lug having an adjustment screw hole, and an adjustment bolt being screwed into the adjustment screw hole.

[0006] Preferably, there are two adjustment ears, located at both ends of the insertion block.

Detailed Implementation

[0016] The technical solution of one embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0017] Please see Figure 1-3 :

[0018] A bottom leveling block mold for a prefabricated bridge crash barrier is disclosed. The main body of the leveling block mold is a frame, which is formed by a front crossbeam 111, a rear crossbeam 112, a left longitudinal beam 122, and a right longitudinal beam 121. The front crossbeam 111 and the rear crossbeam 112 are vertical, while the left longitudinal beam 122 and the right longitudinal beam 121 are horizontal. Slots 1211 are provided along the length of the inner upper side of the left longitudinal beam 122 and the right longitudinal beam 121, respectively. Inserts 132 are provided within the slots 1211, and the inserts 132 have an adjustment structure for adjusting the height of the inserts 132 extending beyond the longitudinal beam. This design allows for adjustment of the height of the inserts 132 extending beyond the longitudinal beam of the left and right longitudinal beams 122 and 121, respectively, while also ensuring that the tops of both are on the same horizontal plane.

[0019] In this embodiment, preferably, the adjustment structure includes an adjustment lug (1221; 1321) located on the insert 132. The adjustment lug (1221; 1321) is provided with an adjustment screw hole 1212, and an adjustment bolt (1222; 1322) is screwed into the adjustment screw hole. In use, the height of the insert 132 extending out of the longitudinal beam plate can be adjusted by rotating the adjustment bolt (1222; 1322), which is very convenient to use.

[0020] In this embodiment, as a preferred embodiment, in order to ensure that the front and rear ends of the insertion block 132 are at the same height, there are two adjusting ears 1321, which are located at the two ends of the insertion block 132 respectively.

[0021] In this embodiment, preferably, since the crash barrier is located on the side of the bridge deck, in order to facilitate the positioning of the leveling block mold, the rear crossbeam plate 112 is connected to a downward-facing rear limiting plate 1121. The rear limiting plate 1122 and the rear crossbeam plate 112 are an integral structure. In use, the inner sidewall of the rear limiting plate 1122 is pressed against the outer sidewall of the bridge deck. Since the rear limiting plate is lower than the bridge deck, the positioning of the leveling block mold in the front-rear direction is achieved.

[0022] In this embodiment, preferably, a fixing post 1223 is provided at the front end of the left longitudinal beam plate 122, and the fixing post 1223 is connected to a hook 1224. After the leveling block mold is positioned, in order to fix the bottom leveling block mold of the prefabricated anti-collision barrier of the bridge slab, the front end of the left longitudinal beam plate 122 is provided with a fixing post 1223, and the fixing post 1223 is connected to a hook 1224. In use, the other end of the hook 1224 is connected to a support member near the leveling block mold.

[0023] In this embodiment, preferably, since the two inserts 132 of the bottom leveling block mold of the precast bridge deck crash barrier are separate structures, during use, the two inserts 132 need to be adjusted to the same height. After one insert 132 is positioned, to facilitate the height adjustment of the other insert 132, the bottom leveling block mold of the precast bridge deck crash barrier also includes a balance detection structure. The balance detection structure is located above the front crossbeam plate 111. The balance detection structure includes two inserts on the left insert 132. The mold includes a left balance detection block 1225 at one end and a right balance detection block 1323 at the front end of the right insert block 132. The right balance detection block 1323 and the left balance detection block 1225 are of equal height, and their lengths are both greater than half the distance between them. The left balance detection block 1225 is L-shaped, with its front section being the left detection section 1226. The right balance detection block 1323 is an inverted L-shape, with its front section being the right detection section 1324. The left detection section 1226 and the right detection section 1324 are of equal length, and their vertical sides are of equal length. In use, by adjusting the adjusting bolts, the left detection section 1226 and the right detection section 1324 are aligned, thereby adjusting the top front ends of the two insert blocks to be at the same height. This describes the front-end balance detection structure. The mold also has a rear-end balance detection structure, which is the same as the front-end balance detection structure and will not be described further here.

[0024] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
