Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a pipe trench shaping and fixing device. Background Art

[0002] At present, during the construction of industrial plants, roads and railways in my country, many rectangular pipe trenches are designed to meet process or drainage requirements. The trench walls are thin, the width is small, the length is long, and the project volume is large.

[0003] During the construction of rectangular trenches, the traditional construction process is for construction workers to first tie the steel bars, then install the trench wall formwork on both sides, and finally fix the formwork with steel pipes. The use of steel pipe reinforcement has low construction efficiency, because the trench width is small, reinforcement is difficult, and the support is unstable. Due to the vibration of pouring concrete, the quality of concrete trench molding is poor, and there are quality problems such as trench distortion and mold expansion.

[0004] The patent document with patent publication number CN219795272U proposes a rapid formwork system for a pipe trench, which supports the formwork and pads through a formwork reinforcement assembly composed of vertical plates, connecting plates, support rods and reinforcing ribs, thereby achieving efficient and stable pipe trench casting. However, in the actual working process, due to the long pipe trench, the above technical solution still needs to be cast in sections during construction, and the formwork and reinforcement system need to be repeatedly reinforced and dismantled during the construction process, and the construction efficiency needs to be further improved.

Two of the four connecting members are evenly spaced at the upper end of the above-mentioned beam, and the remaining two connecting members are respectively connected to the middle parts of the two above-mentioned inclined rods.

[0021] according to Figure 1 As shown, an embodiment of the present application proposes a trench shaping and fixing device, including a fixing bracket 100, wherein the fixing bracket 100 is provided with two groups of casting gaps opening downward, the casting gaps are used to fix a pair of formworks 8, the fixing bracket 100 is a plurality of groups arranged in parallel at intervals, and connecting columns 10 are provided along the extension direction of the plurality of groups of the fixing brackets 100, the fixing bracket 100 is provided with connecting pieces, and the connecting pieces and the connecting columns 10 are snap-fitted together, and the connecting columns 10 connect the plurality of groups of fixing brackets 100 in series into an integral structure by passing through the connecting pieces of the plurality of groups of fixing brackets 10, which can improve the problem of frequent installation and disassembly of the shaping and fixing system of the brackets during segmented casting, reduce labor intensity, and improve work efficiency, and the overall connection structure can further improve the connection stability of the shaping and fixing device, thereby improving the quality of trench casting.

[0022] It should be noted that the multiple fixed brackets 100 are evenly spaced apart along the extension direction of the trench construction, and a casting template 8 is extended on the inner wall of the casting gap on the same side of the multiple fixed brackets 100.
