Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a water-stopping steel plate device with a cover. Background Art

[0002] The horizontal and vertical components of the building's basement cannot be cast in one go due to the temporary water pipes and cables that need to be laid out during construction. Generally, sleeves are used or small holes are reserved directly. The temporary cables and water pipes are removed later and then cast and sealed. However, the sealing effect is not ideal. Leakage is prone to occur at the junction of the new and old concrete pours, and the additional cost of repairing the leakage at that location later is high. Utility Model Content

[0004] In order to achieve the above technical effects, the solution provided by the utility model is to provide a water-stop steel plate device with a cover, which includes:

[0005] A water stop plate, wherein an opening is provided on the water stop plate, and a first flange ring plate is formed by extending upward around the opening, and an outer circumference of the first flange ring plate is provided with an external thread;

[0006] The cover is an internally threaded tube with one end closed, and the internally threaded tube is screwed onto the first flange ring plate.

[0007] Preferably, the first flange ring plate includes a connecting portion connected to the opening of the water stop plate, and a threaded portion connected to the top of the connecting portion and provided with the external thread. The bottom diameter of the connecting portion is larger than the top diameter of the connecting portion, and the internal threaded tube is screwed onto the threaded portion.

[0008] Preferably, the outer edge of the water stop plate extends upward to form a continuous second flange ring plate, and the bottom diameter of the second flange ring plate is smaller than the top diameter of the second flange ring plate.

[0009] Preferably, the water stop plate is annular.

[0010] The beneficial effect of the utility model is that the utility model has a covered water-stop steel plate device, in which the side of the water-stop plate provided with the first flange ring plate is pre-buried toward the water-facing surface, and the temporary water and electricity pipeline can pass through the opening, and after the temporary water and electricity pipeline is removed, the cover can be tightened to carry out secondary pouring. The utility model adds a water-stop steel plate at the joint of the new and old concrete, which plays a role in cutting off the water infiltration path, improves the anti-seepage performance, and reduces the risk of leakage. In addition, the subsequent plugging can be directly cast by tightening the cover, without the need for reinforcing bars and other processes, and the construction is convenient and the plugging effect is good.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 3 As shown, the embodiment of the utility model provides a water-stop steel plate device with a cover, comprising a water-stop plate 1 and a cover 5. Among them:

[0023] like Figure 1 and Figure 2 As shown, the water stop plate 1 is provided with an opening 2, and a first flange ring plate 3 is extended upward around the opening 2, and an external thread is provided on the outer periphery of the first flange ring plate 3. The opening 2 is used to pass water pipes, cables, etc.

[0024] like Figure 3 As shown, the cover 5 is an internally threaded tube with one end closed, and the internally threaded tube is screwed onto the first flange ring plate 3 .

[0025] As a preferred implementation, Figure 2 As shown, the first flange ring plate 3 includes a connecting portion 31 connected to the opening 2 of the water stop plate 1, and a threaded portion 32 connected to the top of the connecting portion 31 and provided with an external thread. The bottom diameter of the connecting portion 31 is larger than the top diameter of the connecting portion 31, and the internal threaded tube is screwed onto the threaded portion 32.

[0026] As a preferred embodiment, the outer circumference of the water stop plate 1 extends upward to form a continuous second flange ring plate 4 , and the bottom diameter of the second flange ring plate 4 is smaller than the top diameter of the second flange ring plate 4 .

[0027] As a preferred embodiment, the water stop plate 1 is annular, and the opening 2 is arranged at the center of the water stop plate 1 .

[0028] The construction sequence of the utility model's covered water-stop steel plate device is as follows (see Figures 4 to 7 shown):

[0029] (1) Prepare the water stop plate 1 and determine the specific location of the temporary water and electricity threading pipe required before the structural construction;

[0030] (2) During the process of tying steel bars and supporting formwork, place the water stop plate 1 and weld it firmly to ensure that the water stop plate 1 is on the center line of the wall and the plate. The support welding of the water stop plate 1 can be done by spot welding small steel bars on the main bars. The side of the water stop plate 1 with the first flange ring plate 3 facing the water surface, and then pour concrete, and bury half of the water stop plate 1 in each of the two concretes. After the installation is completed, remove the cover 5 to connect the water and electricity pipelines. Figure 4 That is, the water stop plate 1 is welded to the main reinforcement through small reinforcement. Figure 5 Structural drawings for the first concrete pour;

[0031] (3) After the temporary water and electricity pipelines are removed, the cover 5 is tightened and the second concrete pouring can be carried out. Figure 6 That is the structural diagram after the cover 5 is tightened. Figure 7 This is the structural diagram of the second concrete pouring.

[0032] The utility model is mainly used for temporary penetration of walls and boards, and for structural parts that need to be sealed later. The joint between the new and old concrete becomes a weak position for waterproofing construction. After adding the waterstop plate 1, when water penetrates along the gap between the new and old concrete joints, it cannot continue to penetrate after encountering the waterstop plate 1. The waterstop plate 1 plays a role in cutting off the water penetration path. The structure is safe and reliable, the construction is relatively simple, the anti-seepage performance is improved, and the risk of leakage is reduced. In the subsequent sealing, the cover 5 can be directly tightened to carry out pouring, without the need for processes such as inserting reinforcement, the construction difficulty is relatively convenient, labor is saved, and the safety and reliability of the structure are improved. The waterstop plate and the cover are used in combination, so that water pipes and cables can be temporarily passed through walls and boards, while preventing leakage at the junction of the new and old poured concrete, and improving the subsequent sealing effect.
