Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a movable roof that opens and closes a roof opening of a building, and more specifically, when a roof member of a movable roof closes a roof opening, The present invention relates to a movable roof that can eliminate differences in level between members.

(Conventional technology) Recently, all-weather stadiums have been attracting attention, and by focusing on the problems of the air membrane structure, the roof can be partially opened and closed depending on the weather, allowing natural lighting and ventilation on sunny days. Also, in order to be able to participate in athletic events even in rainy weather, the present applicant is accommodated by sliding on a fixed roof, and is guided by a guide member through an opening in the inner periphery of the fixed roof. He first proposed a retractable dome roof with a movable roof and a movable roof (Japanese Patent Laid-Open No. 61-79099, Japanese Patent Application No. 61-7909).
1-163592@Refer to the official publication).

Figure 4 shows an example of a movable roof, which is a retractable dome roof 1.
A reinforcing beam 3 provided at the upper edge of a circular side wall 2 erected on the ground, and an annular beam 5 connecting the bases of several roof support beams 4 extending from the side wall 2 toward the center thereof. A donut-shaped fixed roof 7 having an opening 6 in the center of the roof part supported by
It is equipped with

The roof member 8 opens and closes this frontage 6.

The details of the roof member 8 are as follows: The roof member 8 is formed by dividing into two layers concentrically from the center of the opening 6 in the outer radial direction and stacking them. The inner circumferential side is configured as an upper movable door 10, and the opening 6 is opened and closed by slidingly moving it on the support beam 4.

That is, it has a multilayer structure in which a lower movable roof 9 is superimposed on a fixed roof 7, and an upper movable roof 10 is superimposed on it. When these are superimposed on the fixed roof 7, an opening 6 is formed in the center of the dome roof 1. configured.

The movable roofs 9 and 10 are extended from above the fixed roof 7 to close the opening 6, or the movable roofs 9 and 10 are returned to the fixed roof 7 to open the opening 6.

(Problems to be Solved by the Invention) In the conventional movable roof, the movable roof 9.10 is placed on the fixed roof 7.
The movable roof is multi-tiered to match the opening ratio and size of the roof, and each layer overlaps in turn to form a laminated structure.

Therefore, when the opening 6 is closed, as shown in FIG. 5, even if the movable roof member 8 has a single-stage structure, a step is formed in the adjacent portion between the movable roof member 8 and the fixed roof 7. This step creates air resistance for the moving roof, hindering its stability, and has the disadvantage of impairing the airtightness of buildings such as domes.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a movable roof whose roof surface is flat when the roof is closed.

(Means for Solving the Problems) In order to achieve the above object, the movable roof of the present invention supports a movable roof member so that it can move in the direction of movement by a support mechanism that expands and contracts up and down. .

(Function) The support mechanism is retracted when the roof member is in the closed position, and expanded when the roof member is opened.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. To explain an example of a roof having the same shape as the prior art illustrated above, FIG. 1 shows a side view of a dome roof 1, and the base side of the roof support beam 4 is slightly fixed so as to cover a part of the audience seats 11. Covered by 7. The movable roof member 8a has a planar triangular shape that is extended from the fixed roof 7 to the opening 6, and when a plurality of these are arranged horizontally adjacent to each other and the opening 6 is closed, a flat circular dome is obtained.

The moving means has follower carts 12 attached to both wings of the rear end of the roof member 8a, whose rails 13 are laid on the surface of the fixed roof 7, and tracks 14 are laid on the support beams 4. A self-propelled or towed trolley is attached to the center of the tip of the roof member 8a, the tip is supported by a track 14, and the rear end is supported by a rail 13 so that it can run.

The support structure 15, which expands and contracts vertically, is composed of a guide wheel 16 and a column 17 that can move vertically.The column 17 can be used to drive a pantograph with a hydraulic cylinder and a motor cylinder vertically or horizontally. There are things to do. The guide wheels 16 of this support mechanism 15 are constructed of a towable trolley and are attached to the center of the tip of the roof member 8a.

Further, a rain 8i18 is provided at the lower part of the leading edge of the fixed roof 7, and pillars 17 are fixed on both sides of the support beam 4 slightly toward the leading edge thereof, and the guide wheels 16 thereof are brought into contact with the back surface of the roof member 8a. An inverted support column mechanism 15a is provided.

When closing the opening 6, the roof member 8a superimposed on the fixed roof 7 is moved to the closing position by its support mechanism 15.degree. 15a and the follower truck 12 and stopped.

At that time, the follower truck 12 is removed from the fixed roof 7, but the rear part of the roof member 8a is supported by the support column 115a.

From this state, retract the strut 17 of the strut mechanism 15.15a,
To eliminate a difference in level between an adjacent part of a roof member 8a and a fixed roof 7.

The rain gutter 18 is located below the adjacent portion of the roof member 8a and the fixed roof 7, receives rainwater dripping onto the outer surface of the roof member 8a, and drains it to a predetermined location. However, as shown in FIGS. 1 and 2, this adjacent portion is constructed as an inclined end portion that contacts diagonally, and a water-stopping rubber is attached to it, allowing rainwater to directly flow into the rain gutter 8. Never.

When opening the opening 6, first extend the support mechanism 15 (extend the pillar 17), float the roof member 8a so that the follower cart 12 of the roof member 8a rides on the rail 13 of the fixed roof 7, and in this state Move down to Thus, when the moving roof closes the opening, a spherical dome roof is obtained.

(Effects) As described in detail above, according to the movable roof of the present invention,
A movable roof member is supported by a vertically expandable support mechanism, and the support mechanism can be moved according to the position of the roof member when operating nr11, so that a flat roof without steps can be realized. Therefore, it is possible to maintain the stability of the movable roof member by smoothing the flow of air, and to improve the airtightness of the room.
