[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0023] Please see Figures 1 to 4 A protective device for embedded rubber waterstop 10 in longitudinal construction joints includes several protective components 30 extending along the laying direction of the waterstop 10. Each protective component 30 includes a central shaft 32, a torsion spring 33, and protective panels 31. The torsion spring 33 is movably sleeved on the central shaft 32. Two protective panels 31 are respectively disposed on both sides of the central shaft 32 and are respectively connected to the two torsion arms of the torsion spring 33. The central shaft 32 is positioned above the waterstop 10, and the protective panels 31 are inclinedly positioned above the waterstop 10. Under the action of the torsion spring 33, the upper ends of the two protective panels 31 approach each other and clamp the upper end of the waterstop 10, protecting the waterstop 10 while keeping the upper end of the waterstop 10 upright, preventing the waterstop 10 from twisting, and ensuring that the waterstop 10 remains straight during subsequent pouring, thus guaranteeing a good water-stopping effect.

[0024] A torsion spring 33 is sleeved on a central shaft 32, which provides support and guidance for the torsion spring 33 to prevent it from bending. The torsion arms at both ends of the torsion spring 33 are connected to two protective panels 31. To facilitate the connection between the torsion spring 33 and the protective panels 31, a mounting plate 34 is also provided on the central shaft 32. One side of the mounting plate 34 is rotatably sleeved on the central shaft 32, and the other end is detachably connected to the protective panel 31 for easy replacement of the protective panels. Along the direction of the central shaft 32, two mounting plates 34 are located at both ends of the torsion spring 33. The torsion arms at both ends of the torsion spring 33 are welded and fixed to the two mounting plates 34. The torsion spring 33 acts on the mounting plates 34, and through the mounting plates 34, drives the mounting plates 34 and the connected protective panels 31 to rotate, clamping the upper end of the waterstop 10.

[0025] The upper end of the protective panel 31 is connected to the mounting plate 34, and its lower end is supported on the cast-in-place structural surface 20. In a static state, the included angle between the two protective panels 31 is an acute angle. The protective component 30 is triangularly positioned above the waterstop 10 to prevent the waterstop 10 from being contaminated.

[0026] The included angle between the two protective panels 31 and the height of the protective panels 31 should meet the following requirements: when the protective component 30 is placed over the waterstop 10, the top of the waterstop 10 is located between the two protective panels 31, and the top of the waterstop 10 is held by the two protective panels 31. Specifically, the width of the top of the waterstop 10 is greater than the distance between the two protective panels 31 at the same height of the top of the waterstop 10, so that when the protective component 30 is placed over the waterstop 10, the top of the waterstop 10 is located between the two protective panels 31 and forms resistance between them. The two protective panels 31 hold the top of the waterstop 10 under the action of the torsion spring 33. Meanwhile, since the lower end of the protective panel 31 is supported on the cast-in-place structure, the two protective panels 31 provide support for the upper end of the waterstop 10 while clamping it, which can prevent the upper end of the waterstop 10 from tilting and bending and twisting, so that the waterstop 10 remains upright and straight, so that the waterstop 10 can play an effective role in stopping water and preventing leakage during subsequent pouring.

[0027] Preferably, the central axis 32 is set parallel to the laying direction of the waterstop 10.

[0028] In this embodiment, the central shaft 32 is a T-shaped pin, with one end set as a platform and the other end set with a limiting ring. The platform at the end of the central shaft 32 and the two mounting plates 34 form limiting points to prevent the mounting plates 34 from moving axially along the central shaft 32 and detaching from the central shaft 32.

[0029] Preferably, considering the gap between the torsion spring 33 and the central shaft 32, and the gap between the mounting plate 34 and the central shaft 32, in order to effectively prevent the waterstop 10 from being contaminated, a waterproof membrane 35 is provided below the protective component 30. The width of the waterproof membrane 35 can completely cover the protective panels 31 on both sides of the protective component 30, and the length of the waterproof membrane 35 can completely protect the panels 31. The waterproof membrane 35 covers the waterstop 10, and the two protective panels 31 simultaneously clamp the waterproof membrane 35 and the waterstop 10, fixing the waterproof membrane 35 to the waterstop 10. In this embodiment, the waterproof membrane 35 is fixedly disposed on the lower end face of the protective panel 31. When the protective panel 31 clamps the waterstop 10, the waterproof membrane 35 is located inside the protective panel 31, and the waterproof membrane 35 and the protective panel 31 form a double layer of protection above the waterstop 10.

[0030] Several protective components 30 extend along the laying direction of the waterstop 10 to fully cover the waterstop 10, with adjacent protective components 30 overlapping each other. Along the laying direction of the waterstop 10, on the same protective panel 31, a downwardly protruding positioning platform 312 is provided at the bottom rear end of the protective panel 31, and a downwardly recessed positioning groove 311 is provided at the bottom front end of the protective panel 31, such as... Figure 3 and Figure 4 As shown. When two protective components 30 are connected, the positioning platform 312 on the front protective panel 31 can be placed in the positioning groove 311 on the rear protective panel 31 to quickly position and connect the protective panels 31 on the two protective components 30. Both protective panels 31 in the same protective component 30 are provided with positioning grooves 311 and positioning platforms 312, so that when the two protective components 30 are connected, the protective panels 31 on both sides of the central axis 32 overlap one-to-one, thereby avoiding skewing between the protective panels 31.

[0031] Preferably, a plurality of positioning slots 311 are provided at intervals at the front end of the protective panel 31, and correspondingly, a plurality of positioning platforms 312 are provided at intervals at the rear end of the protective panel 31. The number of positioning slots 311 is the same as the number of positioning platforms 312, so as to increase the overlap stability between the protective panels 31.

[0032] Furthermore, both the positioning groove 311 and the positioning platform 312 are provided with fixing holes (not shown in the figure). The fixing holes penetrate the protective panel 31, and fixing members (not shown in the figure) are provided in the fixing holes to fix the protective panel 31 and prevent the protective panel 31 from being displaced by impact during the pouring process. In this embodiment, the fixing member is a steel wire, which passes through the fixing holes on the positioning groove 311 and the positioning platform 312 to fix the two overlapping protective panels 31; as another embodiment, the fixing member can be a bolt.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
