Technical Field

[0001] The present application relates to the technical field of airport concrete pavement construction, and in particular to a temporary plugging device for reserved holes of steel formwork tie rods. Background Art

[0002] There are several longitudinal joints in the airport cement concrete pavement along the longitudinal direction of the runway. There are two types of longitudinal joints: tongue-and-groove joints and tongue-and-groove joints with tie rods. The concrete pavement formwork is generally constructed with a steel formwork body, and holes are evenly distributed along the length of the steel formwork body for setting tie rods. When tie rods are not required for the longitudinal joints, the reserved holes on the steel formwork body need to be sealed to ensure the quality of the concrete construction. Considering that the formwork needs to be used in a turnover manner, the sealing of the holes can only be temporary.

[0003] At present, for the temporary plugging of the reserved holes in the tie rods of the steel formwork body, the oil felt is usually rolled into a cone and then inserted into the hole for plugging, or the oil felt is turned up to the hole for plugging when plugging the gap between the formwork and the base layer.

[0004] In the related art, when sealing the reserved holes of the pull rods, there are problems of low work efficiency and heavy labor burden on workers. Utility Model Content

[0014] By adopting the above technical solution, the first bracket, the second bracket and the limiting bracket are welded and fixed to the side wall of the mortise and tenon body, which limits the blocking plate so that it can only slide along the length direction of the mortise and tenon body.

[0015] Optionally, the first bracket, the second bracket and the limiting bracket are each provided with at least two legs for clamping the mortise and tenon body, and an anti-skid pad is fixed to one side of the legs close to the side wall of the mortise and tenon body, and the anti-skid pad abuts against the mortise and tenon body.

[0016] By adopting the above technical solution, the first bracket, the second bracket and the limiting bracket are clamped on the two side walls of the mortise and tenon body by the supporting feet, which is convenient for disassembly, and the anti-slip pad further enhances the friction and reduces the possibility of detachment.

[0017] Optionally, a groove is formed on one side of the anti-slip pad close to the side wall of the mortise and tenon body, a magnet is fixed in the groove, and the magnet is attracted to the wall surface of the mortise and tenon body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The blocking plate is limited on the mortise body by the limiting assembly and can slide along the length direction of the mortise body. When the blocking plate slides to the side close to the hole, the hole is temporarily blocked. When the tie rod needs to be installed, the blocking plate is slid to the side away from the hole to expose the hole, which is convenient for the installation of the tie rod and improves the efficiency of temporary blocking of the reserved hole of the tie rod of the steel formwork body;

[0025] 2. The handle is provided to further facilitate the movement of the blocking plate and to limit the sliding of the blocking plate in the horizontal direction;

[0026] 3. The first bracket, the second bracket and the limit bracket are all fixed to the two side walls of the tenon body by means of support feet, so as to facilitate their disassembly.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] An embodiment of the present application discloses a temporary plugging device for reserved holes of a steel formwork tie rod.

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 A temporary plugging device for reserved holes of a steel formwork tie rod comprises a transversely arranged steel formwork body 1, a tenon body 11 is provided in the middle of the steel formwork body 1, the tenon body 11 is arranged along the length direction of the steel formwork body 1, and a plurality of holes 111 are spaced apart in the length direction of the tenon body 11, and a plugging mechanism 2 is installed at each hole 111, and the plugging mechanism 2 can quickly realize temporary plugging of the hole 111. When a tie rod needs to be installed at the hole 111, the hole 111 can be quickly exposed for installation, thereby improving the installation efficiency.

[0035] The blocking mechanism 2 includes a blocking plate 21 and a limiting assembly 22. The limiting assembly 22 includes a first bracket 221, a second bracket 222 and a limiting bracket 223 vertically arranged on the mortise body 11. The first bracket 221, the second bracket 222 and the limiting bracket 223 are fixed at intervals along the length direction of the mortise body 11, and the projection of the hole 111 in the horizontal direction is located between the first bracket 221 and the second bracket 222. The first bracket 221, the second bracket 222 and the limiting bracket 223 are all U-shaped. The first bracket 221, the second bracket 222 and the limiting bracket 223 are each provided with two supporting legs 224. The two supporting legs 224 are respectively clamped on the two side walls of the mortise body 11, and the supporting legs 224 are welded and fixed to the side walls of the mortise body 11.

[0036] The blocking plate 21 is slidably installed in the gap between the first bracket 221, the second bracket 222 and the limiting bracket 223 and the mortise body 11, so that the blocking plate 21 can slide horizontally along the length direction of the mortise body 11, and a handle 211 is vertically fixed on the side of the blocking plate 21 away from the mortise body 11, and the handle 211 is located between the second bracket 222 and the limiting bracket 223. The handle 211 further facilitates the sliding of the blocking plate 21. When the handle 211 slides to the side close to the second bracket 222, the blocking plate 21 blocks the hole 111. When the handle 211 slides to the side close to the limiting bracket 223, the blocking plate 21 is away from the hole 111, so that the hole 111 is exposed to facilitate the subsequent installation of the pull rod.

[0037] The implementation principle of Example 1 is as follows: the first bracket 221, the second bracket 222 and the limit bracket 223 are fixed to the mortise body 11 at intervals, the blocking plate 21 is placed between the gaps between the first bracket 221, the second bracket 222 and the limit bracket 223 and the mortise body 11 of the template, and the handle 211 is fixed vertically to the outer side of the blocking plate 21 and is located between the second bracket 222 and the limit bracket 223, which can effectively prevent the blocking plate 21 from falling off. Push the handle 211 to the side close to the limit bracket 223 to expose the hole 111, and then install the pull rod; push the handle 211 to the side close to the second bracket 222 to temporarily block the reserved hole 111.

[0038] Example 2

[0039] Reference Figure 3 The difference between this embodiment and embodiment 1 is that a non-slip pad 225 is fixed on the side of the support foot 224 close to the side wall of the mortise body 11, and the side of the non-slip pad 225 away from the support foot 224 is in contact with the side wall of the mortise body 11. A groove 2251 is provided on the non-slip pad 225, and a magnet 226 is fixed in the groove 2251. The magnet 226 can be automatically attracted and fixed to the wall surface of the mortise body 11, so as to achieve the effect of fixing the first bracket 221, the second bracket 222 and the limiting bracket 223 on the mortise body 11, and at the same time facilitate the disassembly of the first bracket 221, the second bracket 222 and the limiting bracket 223

[0040] A horizontally arranged connecting rod 227 is fixed between the first bracket 221, the second bracket 222 and the limiting bracket 223. A sliding groove 2271 is provided on the upper surface of the connecting rod 227. The sliding groove 2271 is provided along the length direction of the connecting rod 227. The lower side edge of the blocking plate 21 is slidably installed in the sliding groove 2271, thereby further improving the sliding stability of the blocking plate 21.

[0041] The implementation principle of Example 2 is: the first bracket 221, the second bracket 222 and the limiting bracket 223 are attracted and fixed to the tenon body 11 by the magnet 226, which further facilitates the disassembly and replacement of the first bracket 221, the second bracket 222 and the limiting bracket 223. When the blocking plate 21 slides horizontally along the length direction of the connecting rod 227, the slide groove 2271 plays a limiting role, thereby improving the stability during sliding and reducing the falling off of the blocking plate 21.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
