Description

Technical Field

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

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering, concrete and other materials are poured into a mold to form a predetermined shape. When pouring concrete, the free height of the concrete should not exceed 2m. If it exceeds 3m, corresponding measures should be taken. It should include three sections:

[0003] The circular formwork required for the bridge columns before pouring is customized according to the height of the columns, which lacks applicability. At the same time, during pouring, concrete drills into the gaps between the formworks, and an obvious line appears after the mold is opened, affecting the appearance. For this reason, we propose a pouring formwork for bridge construction. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a casting mold frame for bridge construction, which can adjust the height of the mold frame according to the height of the column to be cast, and has higher applicability. At the same time, the 45° mold closing can reduce the open lines caused by casting, so that the surface of the column after casting is smoother, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pouring formwork for bridge construction, comprising a right formwork;

[0006] Right formwork: The left formwork is buckled on its left side. Limit plates are provided on the upper ends of the right and left formworks. The upper ends of the limit plates are inclined surfaces. Limit grooves are provided on the lower ends of the inner walls of the right and left formworks. The upper ends of the limit grooves are inclined surfaces. The inclination angle of the vertical section on the front side of the right formwork is 45°, and the inclination angle of the vertical section on the rear side of the left formwork is 135°. The height of the formwork can be adjusted according to the height of the column to be cast, which has higher applicability. At the same time, the 45° and 135° mold closing can reduce the open lines caused by casting, making the surface of the column smoother after casting.

[0007] Furthermore, it also includes fixing ears, which are evenly arranged on the front and rear sides of the left template and the right template respectively. The fixing ears of the left template are connected to the fixing ears adjacent to the rear side of the right template by bolts to fix the left template and the right template that are interlocked with each other.

[0008] Furthermore, it also includes a fixing seat and a connecting seat, wherein the fixing seats are respectively arranged at the outer lower end of the left template and the outer lower end of the right template, and the connecting seats are respectively arranged at the outer upper end of the left template and the outer upper end of the right template, and the connecting seats are respectively connected to the fixing seats adjacent to the upper end by bolts to connect the upper and lower adjacent left templates and right templates.

[0009] Furthermore, it also includes a hopper, which is buckled on the upper end of the uppermost left template and the right template to form a whole, so as to reduce cement waste.

[0010] Furthermore, a mud-proof groove is provided at the lower end of the inner wall of the hopper, and the mud-proof groove is cooperated with the limiting plate to facilitate taking out the hopper.

[0011] Furthermore, it also includes a base, wherein a limiting ring is provided at the center of the upper end of the base, and the limiting ring is inserted into the interior of the whole formed by the two limiting grooves at the lower end to fix the position of the mold frame.

[0012] Furthermore, fixing holes are symmetrically arranged at the four corners of the upper surface of the base to facilitate fixing of the base.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the pouring formwork for bridge construction has the following advantages:

[0014] 1. Before welding the steel bars, fix the base to the ground where the columns need to be cast through the fixing holes. After welding, buckle the left and right templates, and then connect them through the fixing ear bolts. According to the height of the columns to be cast, set multiple left and right templates to achieve the casting of columns of different heights, which is more applicable.

[0015] 2. The connecting seats of the left and right templates at the lower end are connected to the connecting seats of the left and right templates adjacent to the upper end through bolts to fix the templates. Before pouring, the upper end of the right template at the upper end is buckled with the hopper. During pouring, the anti-mud groove is in close contact with the limiting groove at the lower end, reducing the gap between the concrete flowing into the hopper and the uppermost left template and the uppermost right template, reducing the waste of concrete and facilitating the removal of the hopper. After the concrete solidifies, remove the bolts and open the mold. The inclination angle of the vertical section on the front side of the right template is 45°, and the inclination angle of the vertical section on the rear side of the left template is 135°. It is difficult for concrete to enter the gap, making the surface of the column smoother after pouring. BRIEF DESCRIPTION OF THE DRAWINGS
