Description

Technical Field

[0001] The utility model relates to the technical field of bridge formwork, in particular to a bridge cap formwork. Background Art

[0002] As the name suggests, bridge formwork is a template used in bridge projects. Its application scope includes highway bridges, railway bridges, viaducts, overpasses, etc.; according to different application parts, bridge formwork can be divided into single-chamber box girders (large box girders, small box girders), special-shaped piers, round piers, piers, cap beams, hanging baskets, T-shaped precast beams, and pedestal formwork.

[0003] The existing bridge pedestal formwork is not sufficiently reinforced during the construction process and is very likely to shift due to soft foundations, strong winds, collisions with construction machinery, concrete pouring, vibration, and other conditions, leading to rework problems, which not only delays the construction period but also increases costs. Utility Model Content

[0004] In order to overcome the problem that the existing cap template is not sufficiently reinforced during construction, it is very likely to deviate under various circumstances such as soft foundation, strong wind, collision of construction machinery, concrete pouring, vibration, etc., thus leading to rework, the embodiment of the utility model provides a bridge cap template. The technical solution is as follows:

[0005] A bridge pedestal template comprises side templates arranged in parallel on both sides of the bridge pedestal to be cast, end templates are fixed to both ends of the side templates by bolts, and the side templates and the end templates form a rectangle; a support plate 1 is fixed to the outer side surface of the side template, a connecting rod is hinged on the support plate 1, and the other end of the connecting rod is hinged to a base through a fixing column, and the base is fixed to the ground by a positioning rod.

[0006] Furthermore, support plates 2 are fixed at both ends of the outer side of the side formwork, a T-shaped slot is provided on the upper end surface of the support plate 2, an insert block matching the T-shaped slot is provided in the T-shaped slot, the insert block is tightly fixed to the support plate 2 by positioning bolts, a support rod is hinged at the upper end of the insert block, and the other end of the support rod can be supported on the ground.

[0007] Furthermore, a plurality of triangular supporting feet are fixed to the bottom end of the outer side surface of the side formwork.

[0008] Furthermore, the end template is U-shaped with the open end facing outward, and a plurality of springs are fixed on an outer surface of the end template. The other ends of the springs are commonly connected to an anti-collision plate. Both ends of the anti-collision plate can move along the length direction of the side template. The plurality of springs fixed on the outer surface of the end template and the commonly connected anti-collision plate provide important protection. When encountering external collision or accidental impact, the springs can absorb and buffer the impact force to avoid direct damage to the end template, thereby effectively protecting the integrity of the template structure, extending the service life of the template, and also alleviating the impact to a certain extent, which has a positive effect on preventing the displacement of the base template.

[0009] Furthermore, grooves are provided at both ends of the inner side surface of the side template, and the inner side surface of the end template can be abutted against a side surface in the groove, so that the connection between the side template and the end template is more stable.

[0010] Furthermore, a protective net is fixedly provided on the top of the side formwork, and anti-rust paint is sprayed on the surface of the protective net. The protective net can prevent leaves or foreign objects from entering the concrete and contaminating the concrete during concrete pouring. The anti-rust paint can effectively slow down the corrosion rate of the protective net in the coastal environment with a high chloride ion concentration.

[0011] Furthermore, a gripping rod is fixed to the outer side of the side template to facilitate the movement and installation of the side template.

[0012] Furthermore, the side formwork can be made of carbon fiber, the end formwork can be made of stainless steel plate, and the support plate 1, connecting rod, and fixing column can be made of any corrosion-resistant material such as stainless steel and copper alloy, which can effectively slow down the corrosion rate of each component in a coastal environment with a high chloride ion concentration.

[0013] Furthermore, the anti-collision plate can be made of polystyrene foam (EPS) reinforced material, which is light in weight, high in strength, easy to use and cost-saving.

[0014] The beneficial effects of the technical solution provided by the embodiment of the utility model are: first, the end formwork is fixed with bolts at both ends of the side formwork to form a rectangular structure, which provides a stable and precise molding space for the casting of the bridge pedestal, ensuring the accuracy of the shape of the pedestal and the consistency of the size, and the support plate 1 on the outer side of the side formwork, the connecting rod and the base hinged by the fixed column are fixed to the ground with the positioning rod, which can effectively enhance the overall stability and anti-overturning ability of the formwork, ensure construction safety during the construction process, and reduce quality problems and safety hazards caused by unstable and offset formwork.

[0015] Secondly, the support plates at both ends of the outer side of the side formwork, the inserts in the T-slots and the hinged support rods further provide multi-point support, and the support position and angle can be flexibly adjusted according to actual needs, thereby enhancing the adaptability of the formwork under different working conditions and ensuring that the formwork maintains a good state and stability during the pouring process.

[0016] Finally, several triangular supporting feet at the bottom of the outer side of the side formwork increase the contact area with the ground and improve the bearing capacity of the formwork. They not only effectively disperse the pressure and prevent the formwork from sinking or deforming, but also provide support for the formwork to avoid deviation and overturning, thereby ensuring the construction quality of the bridge pier.
