Description

[Detailed description of the invention] The present invention relates to an upper water stop structure in a four-way water stop gate.

In a water stop gate installed at an estuary or a river confluence, as shown in Fig. 1, an upper water stop rubber 2 is attached to the top of the water gate 1 outside the lower part and both sides, and the water stop rubber 2 contacts the curtain wall 3. When fully closed, water is shut off on all sides to maintain watertightness.

Conventionally, this upper water stop rubber 2 has rubber shaped rubbers 2a and 2b as shown in Fig. 2 or 3 fixed to the upper part of the water gate, but in the former case, the allowable displacement amount of the upper shaped rubber 2a is Since it is small and the connection with the side rubber 4 is complicated, its durability is poor, and in the latter case, the upper rubber 2b cannot follow large deflections, so it has poor sealing performance for large and wide water gates. Furthermore, there are disadvantages in that a curling phenomenon occurs due to the movement of the water gate 1 (which tends to occur when the water gate is opened), and that the upper rubber 2b is severely damaged.

The present invention was devised in view of the above points, and the purpose is to obtain an upper water stop structure for a four-way water stop gate that can sufficiently follow large displacements, is highly watertight, and has good durability. The feature is that the upper part of the waterproof rubber has a cross-sectional shape, and both the upper and lower parts are fixed to the water gate, and the convex part of the central part of the waterproof rubber is in close contact with the curtain wall.

An embodiment of the present invention will be described below based on the drawings.

Figure 4 shows a so-called front four-way water stop gate in which water pressure is applied to the water gate 11 side on the side where the upper water stop rubber 10 is located in the direction indicated by the arrow, and the water gate 11 is lowered and the gate is closed. The structure of the upper water stop section is shown.

The upper water stop rubber 10 provided on the upper part of the water gate door 11 is formed in a cross-sectional shape.
0 has a convex portion 1 in the center for close contact with the curtain wall 12.
0a, the upper part is clamped and fixed to the mounting seat 11a provided on the upper part of the water gate 11 by a presser plate 13, and the lower part is a 〓-shaped mounting seat 11b provided on the water gate 11.
It is clamped and fixed to by a presser plate 14. The mounting seat 11b is provided with a water guide hole 15 for applying water pressure to the back surface of the upper water stop rubber 10.

On the other hand, the side rubber (not shown) has a cross-sectional shape and is connected to the above-mentioned upper water stop rubber 10.

Since the present invention is constructed as described above, even if the dimensional accuracy of the gap between the water gate 11 and the curtain wall 12 is somewhat poor, the upper water stop rubber 10 sufficiently follows the curtain wall 12 and comes into close contact with the curtain wall 12. Since the upper and lower parts of the water rubber 10 are fixed to the water gate 11, when the upper water stop rubber 10 slides on the curtain wall 12, there is no curling up, and therefore damage is less likely to occur and durability is improved. good. Furthermore, connection with the side rubber is easy. In addition, the water guide hole 1 of the mounting seat 11b of the upper water stop rubber 10
Since water is allowed to flow in from 5 and water pressure is applied from the back side of the upper water stop rubber 10, there is an effect that reliable watertightness can be achieved.

In the above embodiment, the upper water stop structure in the front four-way water stop system was explained, but in the case of the rear four-way water stop system, the water stop rubber 10 may be attached upside down.
