Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a road end formwork with a unilateral steel bar support. Background Technique
[0002] During the service period of the concrete surface layer of municipal roads, thermal expansion and contraction phenomena will occur under the influence of temperature changes. In order to prevent the concrete surface layer from cracking and warping due to the expansion and contraction effects, vertical and horizontal joints that intersect perpendicularly should be set on the concrete surface layer, so that the temperature stress is released at the joint position without damaging the concrete surface layer.
[0003] The expansion joint is an important form among the vertical and horizontal joints. Tie bars or dowel bars (steel bars) need to be set at the expansion joint position to transfer the load and thus improve the mechanical integrity between adjacent two panels. In the case of discontinuous pouring, the expansion joint is usually constructed by the fixed method of the head wood formwork. This method has more formwork components and low assembly efficiency, and cannot provide effective support and limit for the main road steel bars. During the concrete pouring and vibrating process, the main steel bars are prone to shift, affecting the construction quality of the concrete road. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a road end formwork with a unilateral steel bar support, which is convenient for installation, provides a support effect for the main road steel bars, ensures the stability of the main steel bars, and avoids the influence of the disturbance of the concrete on the main steel bars during the concrete pouring and vibrating.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is a road end formwork with a unilateral steel bar support, including:
[0006] An end formwork body for abutting against the end of the road steel cage, and a plurality of first through holes for the corresponding penetration of a plurality of main steel bars of the road steel cage are arranged at intervals along the length direction on the end formwork body;
[0007] A support plate for assisting in supporting the plurality of main steel bars, the support plate is arranged on the side of the end formwork body facing away from the road steel cage, the support plate is arranged parallel and spaced apart from the end formwork body, and a plurality of second through holes for the corresponding penetration of the plurality of main steel bars are arranged at intervals along the length direction on the support plate;
[0008] A plurality of connecting bars, and the plurality of connecting bars are connected at intervals between the support plate and the end formwork body.
[0009] A further improvement of the road end formwork with unilateral steel bar support of the present utility model lies in that clamping plates are further connected to both ends of the formwork body, and both of the clamping plates extend towards the direction of the road steel reinforcement cage. In the installation state of the formwork body, the two clamping plates respectively block the relative outer sides of the side formworks on both sides of the road steel reinforcement cage.
[0010] A further improvement of the road end formwork with unilateral steel bar support of the present utility model lies in that diagonal braces are connected to the relative outer sides of the formwork body and the relative outer sides of the two clamping plates.
[0011] A further improvement of the road end formwork with unilateral steel bar support of the present utility model lies in that the formwork body is a steel plate.
[0012] Compared with the prior art, the advantages of the present utility model are as follows:
[0013] By providing a support plate and opening a plurality of second through holes in the support plate, each main reinforcement passes through the first through hole and the second through hole in sequence. Two points form a line, providing a stable support effect for each main reinforcement and avoiding the influence of the disturbance of the concrete during concrete pouring and vibration on the main reinforcement.
