Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pouring, and in particular relates to a dam pouring template. Background Art

[0002] In the construction of water conservancy and hydropower projects, the design of major hydraulic structures such as dams and cofferdams has increasingly adopted full roller-compacted concrete structures. In order to achieve the goal of rapid and uninterrupted continuous construction of roller-compacted concrete, the existing technology generally adopts flip formwork for pouring. However, the angle between adjacent flip formworks is usually unable to be adjusted and is not suitable for the curved section of the dam.

[0003] The Chinese patent with announcement number CN220927854U discloses a universal flip formwork device for the straight section and reverse arc section of the dam. The scheme includes an upper panel, a lower panel and a support frame. The upper panel and the lower panel are respectively connected to the upper and lower parts of the support frame by connecting parts. The upper and lower end faces of the upper panel and the lower panel are both at acute angles to their working surfaces. The lower end of the support frame is hinged with a connecting plate and an adjusting screw mechanism for connecting adjacent support frames during construction. The above scheme uses connecting parts to connect the upper panel and the lower panel to the assembled support frame, and adjusts them until the working surfaces of the upper panel and the lower panel are at the required design angle. Then, the first set of flip formwork devices is fixed, and the remaining flip formwork devices are installed in sequence from bottom to top to achieve the adjustment of the assembly angles of adjacent panels, so as to be suitable for the construction of the straight section and reverse arc section of the dam.

[0004] In the process of assembling the remaining flip template devices from bottom to top in the above scheme, the contact area between the upper panel located below and the adjacent lower panel located above is small, and the friction between the two is small. In the process of operating the adjusting screw mechanism, the two adjacent flip template devices are prone to relative movement, requiring repeated adjustments, resulting in low installation efficiency.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A dam casting formwork includes a support unit and a screw adjustment mechanism, wherein the support units are provided in plurality, and each group of support units includes a panel and a support frame, the front wall of the panel is provided with a plurality of anchor rods in an array, the left and right ends of the top of the panel are respectively fixed with connecting plates, and the bottom of the panel is provided with a connecting block with a semi-cylindrical bottom between the two connecting plates, the support frame is fixedly provided on the front side of the panel, and the upper and lower sides of the front end of the support frame are respectively fixed with connecting ears, and the plurality of support units are connected in sequence up and down and left and right, and the connecting blocks of each panel are respectively rotatably connected to the connecting plates of the adjacent panels below through round pins, and the screw adjustment mechanism is provided in plurality, and each screw adjustment mechanism is provided between two adjacent support units above and below, and is respectively rotatably connected to the two adjacent support frames.

The mounting plate is fixedly arranged on the rear side of the first support rod, and the two second support rods are respectively located on both sides of the first support rod and are respectively fixedly arranged on the front wall of the mounting plate. The two ends of the first support rod and the two second support rods away from the mounting plate are respectively fixedly connected to the adjacent back plates by bolts.

[0021] Through the above arrangement, the rigidity of a single group of support components can be enhanced, and at the same time, the support frames of the two adjacent support units on the left and right are fixedly connected, thereby further improving the integrity of the utility model.

[0022] In the present invention, the screw adjustment mechanism includes a threaded rod, a rod sleeve and a mounting seat.

[0023] The principle and effect of this technical solution:

[0024] After the two adjacent panels are rotated and connected, pull the mounting seat so that the top of the mounting seat is aligned with the adjacent upper connecting ear, then slide the insertion rod into the mounting seat and the corresponding connecting ear, and rotate the rod sleeve. Since the threaded rod cannot rotate with the rod sleeve, the threaded rod moves relative to the rod sleeve as the rod sleeve rotates, and the total length of the threaded rod and the rod sleeve changes, thereby driving the adjacent upper panel to rotate.

[0025] Through the above arrangement, the purpose of adjusting the angle of the working surfaces of the panels of the two groups of support units by operating the screw adjustment mechanism and fixing the panel of the next support unit is achieved, thereby improving the practicality of the utility model.
