[0002] At present, with the increasing competitive pressure in the construction market, high-efficiency and high-quality construction have become essential skills for military strategists. When constructing the reserved grooves for civil air defense door and movable thresholds, due to the problems of civil air defense acceptance and construction sequence process, the reserved grooves for civil air defense door and movable thresholds need to be reserved in advance when pouring the bottom plate concrete. At this time, the double-layer bidirectional steel bars of the raft slab have been tied, resulting in difficulty in reinforcing the reserved groove templates at this location. Conventional all-wood template support and reinforcement have many disadvantages. First, in terms of materials, workers will cut the entire template into a notch shape for passing steel bars. Due to the limitation of the steel bar spacing, the entire template is cut into short strips smaller than the steel bar spacing, and the entire wooden square is cut into small sections, so that it cannot be reused, which greatly reduces the turnover times of the wooden squares and templates, resulting in waste; secondly, the reinforcement of short strip templates and wooden square joints is limited by the space width of the reserved groove, and cannot be nailed and reinforced smoothly and quickly; thirdly, after the concrete is poured, the short strip template is subject to the side pressure of the concrete and the fixing effect of the nails, making it difficult to carry out the rapid and protective removal of the template. In summary, some construction companies fail to reserve grooves when constructing raft concrete, and later chisel and cut grooves in the raft, damaging and disturbing the steel bars on the raft, causing quality problems.

[0032] To facilitate understanding of the present invention, the following description is given with reference to the accompanying drawings and embodiments.

[0033] See also Figures 1 to 3 The present invention provides a template system for forming a reserved groove. A steel cage is arranged on the ground at a position corresponding to the reserved groove to be formed. The template system includes a plurality of sequentially connected and U-shaped unit modules and two end templates 63 fixed to the ends of the unit modules at the ends. The plurality of unit modules and the two end templates 63 enclose a closed space. The unit modules include:

[0034] A template 6 having a U-shaped vertical section;

[0035] The U-shaped member 1 is connected to the side of the template 6 in an adjustable position and is detachably connected to the steel cage. A number of unit modules are placed in the steel cage through the gap of the steel cage, and then the U-shaped member 1 is connected to the steel cage, and then the overlapping length of the U-shaped member 1 and the template 6 is adjusted to connect adjacent unit modules.

[0036] A preferred embodiment of the template system for forming the reserved groove of the present invention is as follows: Figure 2 and Figure 3 As shown, the U-shaped part 1 includes two L-shaped plates arranged opposite to each other, a connecting plate 13 fixed vertically to the side of the L-shaped plate close to the other L-shaped plate, and a plurality of pin holes spaced apart on the connecting plate 13. The two connecting plates 13 are fitted together and then pins are inserted into the pin holes of the two connecting plates so that the two L-shaped plates are assembled into a U shape.

[0037] Preferably, if Figure 1 and Figure 4 As shown, the L-shaped plate includes a vertical first folding plate 11 and a second folding plate 12 vertically connected to the bottom of the first folding edge 11 , and a connecting plate 13 is vertically fixed to the second folding plate 12 .

[0038] Specifically, such as Figure 1 and Figure 3 As shown, it also includes a wooden square clamped between two connecting plates 13, and a pin is inserted into the wooden square. By changing the width of the wooden square, the width of the U-shaped member 1 can be changed to match the width of the reserved groove to be formed.

[0039] Furthermore, the template includes two side templates 62 arranged opposite to each other and a bottom template 61 connected to the bottom of the two side templates 62. The side templates 62 are adjustably connected to the sides of the L-shaped plate, and the bottom template 61 is connected to the bottom of the two L-shaped plates.
