[0018] The following further clarifies the present utility model in conjunction with the drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. Embodiment

[0019] As Figure 1As shown in Figures 3(a) and 3(a), a waterstop steel plate fixing device described in this embodiment is such that the floor slab needs to be cast together with the wall. It includes a portal frame 5 and a pair of bolts 6. The portal frame 5 is composed of three steel pipes, including long steel pipes 7 on both sides and short steel pipes 8. The two steel pipes on both sides are welded into a whole through the top horizontal steel pipe 9. The bottom of the long steel pipe 7 is connected to an adjustable base 3, and an adjustable vertical rod 2 is provided at the bottom of the short steel pipe 8. The bottom end of the adjustable vertical rod 2 is supported by a plane strut 1. The long steel pipe 7 and the short steel pipe 8 are provided with holes on the side surfaces. The pair of bolts 6 respectively pass through the long steel pipe and the short steel pipe, and the pair of bolts 6 are symmetrically arranged. The plane strut adopts the C16 model, with a length greater than 100 mm of the raft slab height. The adjustable base 3 and the adjustable vertical rod 2 adopt the specification of Φ38×6.5×500 mm. The portal frame adopts Φ48*3.2 steel pipe. The width of the portal frame is 400 mm. The bolts adopt the M16 specification and have a length of 250 mm. This device takes the same-layer plane of the construction wall as the bearing point, and the fixing devices are evenly arranged at intervals of 500 mm in the structure where the waterstop steel plate needs to be set (as shown in Figure 2 ), effectively avoiding the use of welding to fix the waterstop steel plate and not affecting the original design structure of the wall. By adjusting the nut 4 to adjust the height of the bolt 6, the position of the bolt 6 is the fixing point of the waterstop steel plate 11. The fixing point is 50 mm above the midpoint of the waterstop steel plate. Place the waterstop steel plate 11 and tighten the bolts to fix the waterstop steel plate. Tie the original design stirrups 13 of the wall at the bottom of the waterstop steel plate. When pouring, use the midpoint height of the waterstop steel plate as the pouring positioning horizontal line. The device can be removed 24 hours after pouring and transferred to the next structure where the waterstop steel plate needs to be set. At the same time, cut the part of the plane strut that exceeds the height of the cast floor slab 16. Embodiment

[0020] The difference between this embodiment and Embodiment 1 is that as shown in Figure 1 Figures 3(b) and 3(b), the floor slab does not need to be cast together with the wall. Place a 200*200 wooden square 10 under the plane strut. The device can be removed 24 hours after pouring and transferred to the next structure where the waterstop steel plate needs to be set (without cutting the plane strut).

[0021] The waterstop steel plate fixing device of the present utility model bears the weight of the waterstop steel plate through the adjustable base, adjustable vertical rod, plane strut, frame body, and bolts, and adjusts the original design wall stirrups to the bottom of the waterstop steel plate as an additional load-bearing measure. At the same time, the bolts play a fixing role to ensure the stability of the waterstop steel plate without overturning. This device is convenient for construction, saves materials, does not require welding, and is environmentally friendly.

[0022] It should be noted that the above content only illustrates the technical idea of the present utility model and cannot be used to limit the protection scope of the present utility model. For those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements all fall within the protection scope of the claims of the present utility model.
