Description

Technical Field

[0001] This utility model relates to the field of guardrail casting mold technology, and in particular to a splicing casting mold for highway bridge safety crash guardrails. Background Technology

[0002] Bridge railings are guardrails installed on bridges to prevent out-of-control vehicles from going off the bridge. They serve to prevent vehicles from breaking through, passing under, or overturning the bridge, and also enhance the aesthetics of the bridge structure. The selection of bridge railing types should first be based on the highway grade, comprehensively considering factors such as safety, coordination, the characteristics of the protected object, and site geometry to determine the collision protection level. Then, the structural form should be selected based on factors such as the railing's structure, economy, construction, and maintenance. There are three installation methods: direct embedment of posts, flange connection, and casting the bridge railing and bridge deck into one piece using reinforcing steel bars. When conditions permit, replaceable railings can be used. Casting molds are used during the railing casting process.

[0003] However, in practical applications, the mold needs to be assembled before the guardrail is poured to facilitate subsequent installation. If it is inconvenient to install and position the mold, it will affect the ease of use of the splicing and pouring mold and reduce its efficiency. Utility Model Content

[0015] The pull rod allows for easy limiting of one side of the mold during use, maintaining the stability of the mold installation.

[0016] In a preferred embodiment, a threaded rod is inserted into the receiving plate. One end of the threaded rod passes through the inner template and extends to the outside of the inner template. Threaded blocks are fitted on both ends of the threaded rod, and threaded holes are provided on the threaded blocks for threaded connection of the threaded rod.

[0017] The threaded blocks facilitate threaded connection during use, which is convenient for subsequent use and also maintains the connection stability of the components.

[0018] In a preferred embodiment, both the receiving plate and the inner template are provided with circular holes for the threaded rod to pass through. The circular holes are adapted to the threaded rod, and the surface of the threaded rod is slidably connected to the inner wall of the circular holes.

[0019] The threaded rod facilitates positioning during use and maintains the connection stability of the component, making it convenient for subsequent use.

[0021] The buffer plate is reset by the buffer spring, which allows the limit rod to be inserted into the top of the receiving plate. This increases the connection stability between the outer template and the receiving plate, prevents loosening, and improves the stability of the two in use. It also facilitates subsequent operations and improves the ease of use of the mold.

[0022] As can be seen from the above, the splicing and casting mold for highway bridge safety crash barriers provided by this utility model has the following technical effects.

[0023] Firstly, by using the outer template, inner template, and screw, the positioning block and nut can limit the outer template and inner template during use, thereby preventing the inner template and outer template from separating. At the same time, tightening the screw ring allows the arc rod to compress and position the component during use, thereby preventing loosening during subsequent use and improving the stability of the component.

[0024] Secondly, the buffer spring resets the buffer plate, allowing the limiting rod to insert into the top of the receiving plate. This increases the connection stability between the outer template and the receiving plate, preventing loosening and improving the stability of their use. It also facilitates subsequent operations and enhances the ease of use of the mold. Attached Figure Description

[0033] The outer template 3, inner template 4, and screw 6, together with the positioning block 7 and nut 8, can limit the outer template 3 and inner template 4 during use, thereby preventing the inner template 4 and outer template 3 from separating. At the same time, tightening the screw ring 12 allows the arc rod 11 to perform a compression positioning operation on the component during use, thereby preventing loosening during subsequent use and improving the stability of the component.

[0034] A threaded rod 14 is inserted into the receiving plate 2. One end of the threaded rod 14 passes through the inner template 4 and extends to the outside of the inner template 4.
