Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a single-sided formwork construction diagonal bracing structure. Background Technology
[0002] Single-sided formwork (also known as single-sided support formwork or single-sided template) is a special formwork construction technique in civil engineering. Its core feature is that during concrete pouring, only one side of the structure is equipped with formwork and support system, while the other side relies on the existing structure (such as retaining wall or soil) or temporary measures to bear the load. This method is suitable for walls with narrow construction surfaces or walls that can be supported on one side, especially when the wall is close to the retaining piles of the foundation pit (such as underground diaphragm wall), in which case only the single-sided support formwork method can be used for construction.
[0003] A search revealed that patent CN221779018U discloses a single-sided support device for aluminum alloy templates. This device uses a rotating screw to move a moving block, which in turn moves a support rod. The support rod's movement causes an extension plate to move upwards, with the extended portion contacting the upper part of the aluminum alloy template. Together with the support rod and support base, it stably supports the aluminum alloy template. The height of the extension plate can be adjusted according to the size of the template to provide stable support. This allows the device to support aluminum alloy templates of different sizes, eliminating the need for workers to physically carry different sized templates, thus simplifying its use.
[0004] While the above solution can drive the support rod to move by rotating the screw to provide diagonal bracing for the support plate and thus support the template, in actual operation, it requires rotating the screw to move the moving block connected to the support rod a long distance to rotate the support plate to the required angle. This operation is time-consuming, and the structure of this solution is relatively complex, resulting in high production and processing costs. Therefore, we propose a single-sided formwork construction diagonal bracing structure. Utility Model Content
[0005] The purpose of this invention is to provide a single-sided formwork construction diagonal bracing structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

A channel steel is rotatably connected to one end of the top of the steel plate. The outer wall of the channel steel has multiple threaded holes for installing set screws. Multiple round rods are fixedly installed inside the channel steel. A telescopic rod is hinged to the other end of the top of the steel plate. The telescopic rod includes a sleeve with one end hinged to the steel plate. An inner tube is movably installed at the other end of the sleeve. A positioning mechanism for the inner tube is installed on the sleeve. A nut is fixedly connected to the end of the inner tube outside the sleeve. A screw rod fits through the nut. A U-shaped top head is fixedly connected to the end of the screw rod outside the nut via a set screw. The U-shaped top head is adapted to the round rod.
[0008] As a further embodiment of this utility model: the positioning mechanism includes two positioning bolts, and two screw holes are symmetrically opened on the outer wall of the sleeve near its opening end. The positioning bolts are fitted into the corresponding screw holes. Multiple annular positioning grooves are equidistantly opened on the outer peripheral wall of the inner tube. The end of the positioning bolt is a smooth rod, and the smooth rod is located in an annular positioning groove.
[0009] As a further embodiment of this utility model: a connecting seat is fixedly installed at one end of the top of the steel plate, the top end of the connecting seat is located inside the channel steel, and a pin is rotatably installed on the connecting seat, and the pin is fixedly connected to the channel steel.
[0010] As a further embodiment of this utility model: the closed end of the sleeve is hinged to the top of the steel plate via a hinge seat.
[0011] As a further improvement of this utility model, it also includes a plurality of pile nails, which are adapted to the through holes.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In use, this invention involves fixing the steel plate to the ground with pile nails, then rotating the channel steel and telescopic rod on the steel plate. Next, the U-shaped mandrel is fitted onto the required matching round rod, and then the nut is rotated. The nut and screw work together to drive the screw to move outward from the inner tube, thus lifting the channel steel to the desired angle. Wooden blocks are then placed between the template and each set screw, and the set screws are tightened to secure the template. The operation is simple and convenient. After pouring and removing the template, the telescopic rod and channel steel can be rotated onto the steel plate to fit snugly, facilitating storage and transportation of the device and enabling rapid turnover.
