Description

[Detailed description of the invention] <Industrial application field> This invention relates to a water-stop structure for movable roofs, and is particularly suitable for ensuring water-stop properties between movable roofs of retractable roofs that can be opened and closed according to the weather. .

<Conventional Technology> In recent years, large buildings such as baseball stadiums and track and field stadiums have been equipped with roofs on top of the buildings for the purpose of regulating lighting and temperature, as well as protecting the inside of the buildings during rainy weather. It has been proposed that part of the system be openable and closed.

Figures 3a and b show the retractable dome roof (Japanese Patent Application No. 60-9137 (Japanese Unexamined Patent Publication No. 61-1989) that was developed earlier by the present inventor.
(Refer to Publication No. 169541)). This roof basically consists of a fixed roof 1 in which a circular opening 2 is formed, an annular beam 4 provided around the entire circumference of the opening 2 of the fixed roof 1, and a fan-shaped opening 2. A movable roof 3 is formed with an external contour divided into a plurality of parts, and is provided so as to be movable from above the fixed roof 1 toward the center of the opening 2 in order to cover the opening 2 in an openable and closable manner. It is comprised of a plurality of guide beams 6, which are arranged to extend in the radial direction from the annular beam 4 to the center position of the opening 2, and guide the movement of the movable roof 3 while supporting it.

That is, the roof structure is a ring-shaped fixed roof 1 with a circular opening 2 formed in the center and an outer peripheral edge supported by an outer wall (not shown).
and a plurality of movable roofs 3 disposed on a fixed roof 1 so as to be movable toward an opening 2 at the center thereof. The movable roof 3 is formed into eight substantially identical sector shapes divided into eight pieces at equal angular intervals from the center of the circular opening 2 in the central portion of the fixed roof 1. An annular beam 4 is provided around the entire periphery of the opening 2, and a beam holder 5 is arranged at the center of the opening 2, and between the annular beam 6 and the beam holder 5, the opening 2 A plurality of guide beams 6 are extended in the radial direction within the movable roof 3, and these guide beams 6 are configured to guide the movement of each movable roof 3 while supporting it along the center line from its apex to its bottom. has been done. Also,
A pair of guide rails 7 are provided on the fixed roof 1 to support and guide both left and right ends of each movable roof 3.
are provided in parallel at the same width intervals as the outer width of the movable roof 3.

FIG. 3a shows the state in which the movable roof 3 is retracted and stored on the fixed roof 1. To close the opening 2 with the movable roof 3 from this state, each movable roof 3
is moved toward the center of the opening 2 along the guide beams 6 and guide rails 7, and the apex of each moving roof 3 is aligned with the center of the opening 2 as shown in FIG. 3b.

On the other hand, FIG.
(Refer to Japanese Unexamined Patent Publication No. 169540/1983)), in which the plurality of guide beams 6 are supported by the fixed roof 1 so as to be expandable and contractible from the fixed roof 1 side toward the inside of the opening 2. The movable roof 3 is provided so as to be able to extend and extend into the opening 2, and the movable roof 3 is provided integrally with each guide beam 6, and moves together with the guide beam 6 from above the fixed roof 1 to the opening 2 to open the opening. It is configured so that the section 2 can be opened and closed.

In the above configuration, water-stopping properties at the joint edges 3a of the side edges of the movable roof 3 that come into contact with each other when the opening 2 is closed poses a problem.

That is, since the joining edges 3a of the movable roofs 3 are repeatedly joined and separated according to the opening/closing operation of the opening 2, it is difficult to ensure the sealing performance between these joining edges 3a. In addition, this joining edge 3a
It is conceivable to overlap the panels using a drainage board, etc., and ensure water-stopping properties with this overlapping structure, but it is not possible to sufficiently stop water from rain accompanied by wind blowing from the side. There are some difficult problems.

In order to solve the above problem, conventionally, as shown in FIG.
A sealing material 9 having a hollow flexible part 8 was attached to the part a, and this hollow flexible part 8 was pressed against the other, thereby maintaining water-stopping properties.

<<Problems to be solved by the invention>> However, in the above-mentioned conventional water stop device, the contact portion of the hollow flexible portion 8 is fixed at one point, or the flexible hollow portion 8 is fixed at one point as shown in the figure. Since only two locations, upper and lower, can be secured according to the deformation, if the contact force at the contact portion is low, sufficient watertightness between the two cannot be ensured, leading to the risk of water leakage. In addition, if there is a large amount of rainwater, the rainwater will accumulate in the upper part of the upper contact area of both hollow flexible parts 8, and the weight of the rainwater will be
If the contact force exceeds the contact force of , a gap is created between these sealing materials 9, and there is a risk that rainwater may flow in through the gap and cause water leakage.

This invention was devised in view of the above-mentioned problems, and its purpose is to more reliably ensure water-tightness with a simple structure when closing an opening with a movable roof. The objective is to provide a water-stop structure for movable roofs with retractable roofs.

<<Means for Solving the Problems>> In order to achieve the above object, in this invention, a fixed roof 1 having an opening 2 formed therein is moved toward the opening 2, and the joining edges 3a thereof are joined together.

The engaging portions 22b are configured to engage with each other within the engaging recesses 50a and 50b.

Next, the operation of the above embodiment will be explained. As shown in FIG. 3, from the state where the movable roof 3 is retracted and stored on the fixed roof 1, each movable roof 3 is moved along the guide beam 6 and the guide rail 7 to close the opening 2. In the process of moving the movable roof 3 toward the center of the
When the movable roofs 3 gradually approach each other from the state before they are joined as shown in FIG. Contact. Furthermore, when the two are brought close together and joined to each other and the opening 2 is closed, as shown in FIG. flexible cylindrical portion 16a,
Due to the air filled in 16b, the upper and lower parts come into contact with each other in a press-contact state accompanied by elastic deformation.
Meanwhile, at the same time, the first and second elastic sealing materials 12
The first engaging portions 22a, 22b of the fitting protrusions 18a, 18b of each of
moves forward while moving upward or downward along the external contour of the flexible cylinder portions 16b, 16a, and passes over the second engaging portions 24b, 24a of the flexible cylindrical portions 16b, 16a to engage the engaging recess 50.
b, 50a to be removably fitted and engaged. In this engaged state, the fitting protrusions 18a, 18b are slightly expanded outward by the bulged second engaging portions 24b, 24a, so the elastic restoring force resists this expansion. The engagement force between the two is becoming stronger. In particular, at this time, as shown in FIG. 1b, the first and second elastic sealing materials 12a and 12b are pressed against each other at four locations, which are not arranged on the same plane. Furthermore, first and second elastic sealing materials 12
The upper part of the press-contact parts a and 12b is covered by the flange 16d of the second elastic sealing material 12b.

As a result, most of the rainwater is transferred to the first engaging portion 22a of the fitting protrusion 18a of the first elastic sealing material 12a, which performs a draining function, and the collar portion of the second elastic sealing material 12b, which functions as a cover. 16d, the first and second elastic sealing materials 12a, 12b

The inflowing rainwater is also absorbed by the close contact between the first engaging portion 22a of the first elastic sealing material 12a and the second engaging portion 24b of the second elastic sealing material 12b. , it is prevented from flowing inwardly, and is discharged along the gutter formed by the engagement recess 50b above the flexible cylindrical portion 16b of the second elastic sealing material 12b. Furthermore, even if a large amount of rainwater flows in and accumulates in the space above the fitting protrusion 18b of the second elastic sealing material 12b, the weight of the rainwater is absorbed by the first elastic sealing material 12a. Second
This acts to strengthen the degree of adhesion between the engaging part 24a of the second elastic sealing material 12b and the first engaging part 22b of the second elastic sealing material 12b, so that it is possible to reliably prevent the material from flowing into the interior. Further, even if rainwater flows further downward beyond these contact areas, it can be discharged to the outside by the gutter formed by the engagement recess 50a of the first elastic sealing material 12a.

FIG. 2 is a sectional view showing a second embodiment of the present invention. In this embodiment, unlike the above-described first embodiment, a concave groove 26 is formed in the vertical center of the joint edge 3a of the movable roof 3, and on the other hand, the base portion 14a of the elastic sealing materials 12a, 12b is , 14b
Anchor portions 28a and 28b are integrally protruded from the center of one side. Then, the anchor portions 28a and 28b are fitted into the concave groove 26,

This improves water-stopping performance against water leakage between the joint edge 12b and the joint edge 3a.

The other configurations and operations are the same as those of the first embodiment, so their explanation will be omitted.

Furthermore, in the scope of the utility model registration claim, it is stated that "the joining edges 3a are in contact with each other", but this does not necessarily mean that both movable roofs 3 need to be moved at the same time, and that one of them has already been moved. This also includes cases where the location has been fixed after completing the process.

<<Effect of the invention>> As described above, in this invention, a set of elastic sealing materials is provided along the longitudinal direction of each of the pair of joining edges 3a of the movable roofs 3 that are adjacent to each other and are brought into contact with each other. 12a and 12b are provided, and the pair of elastic sealing materials 12a and 12b are pressed against each other and elastically deformed.
