Description

TECHNICAL FIELD The present invention relates to a retractable space truss roof for an atrium.

Conventional technology The atrium roof, which is installed inside a large building and has a glass roof in a large stairwell reaching the top of the building, is fixed to the conventional building, and the ventilation of the huge atrium space is properly performed. In order to do so, a very large-scale ventilation facility is required, and there is a difference in that the glazed glass is different from so-called natural lighting, and a sufficient open feeling cannot be obtained.

For the purpose of solving these problems, the present inventors separately proposed an atrium roof having an atrium roof as an open / close roof.

In general, as a supporting traveling means for supporting and traveling a moving object, one moving object is usually supported by two wheels on each side, that is, a total of four wheels. However, the large moving roof of the atrium reaches about 30m x 30m, and
Even if it is divided into pieces and moved to both sides from the dividing line to open it, it reaches about 15 m × 30 m and it is extremely heavy, and if this weight is supported by 4 wheels and allowed to run, it is an allowable ground contact. Due to the pressure, the diameter of one wheel and the width in the axial direction are extremely large, and the rail for mounting this wheel also has a large cross-sectional dimension in order to obtain the required strength. If the height from the roof of the laid building to the top of the atrium roof is large and the building height is limited, the height of the building itself is low.

Therefore, it is possible to reduce the load per wheel by increasing the number of wheels on each side, but in order to support the load with three or more wheels on each side, steel truss, wheels, rails, etc. Unless the manufacturing precision of the above is increased and the manufacturing is performed with strict precision, one of the wheels floats up, and no load is applied to the floating wheel, resulting in an imbalanced load on each wheel. In addition, when many wheels are attached, a bogie trolley is generally used because many wheels have to be passed straight. If a bogie is adopted, it has the advantage of smooth movement, but on the other hand, the structure becomes complicated, and the height from the rail surface to the lower chord core of the truss also becomes high.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention solves the above-mentioned problems that occur when an atrium roof is used as an opening / closing roof, and the height from the rooftop to the top of the atrium roof is not high, and the height from the ground is high. An object is to provide an atrium open / close type three-dimensional truss roof that can reduce the found area.

Means for Solving the Problems In order to solve the above problems, the present invention relates to an atrium that can be opened and closed by traveling on rails laid on the roof by wheel rows provided on both sides in the moving direction for opening and closing. In a retractable space truss roof, the above-mentioned wheels are installed on both sides of the space truss at approximately the intersections of the lower chord member and the lattice member, and are connected to the vertical truss on the wheel train and the upper contact point of the vertical truss. It is characterized in that the end portion is omitted and the roof material is obliquely attached to both side surfaces of the space truss, and the rigidity of the truss to which the wheel train is attached is reduced in the wheel train direction.

Work Since the wheels that support and run the open-close type space truss roof of the atrium are installed at the intersections of the lower chord members and the lattice materials on both sides of the space truss as described above, two wheels are installed on each side of the space truss. The number of wheels on both sides of the truss is increased compared to. Even in that case, since the vertical truss on the wheel train and the end of the upper chord member connected to the upper contact of the vertical truss are omitted, the rigidity of the truss having the wheel train mounted in the wheel train direction becomes small, and the rail Unevenness in the vertical direction of
Even if there are wheel mounting and dimensional errors, the truss flexes easily and easily follows, and in each row, all wheels do not float above the rails, and the load of the atrium roof can be shared evenly. Therefore, the load per wheel is reduced, the cross-sectional dimension of the rail and the diameter of the wheel can be reduced, and as a result, the height from the rooftop to the top of the atrium roof can be reduced.

Further, since the vertical truss on the wheel train and the end of the upper chord member connected to the upper contact point of the vertical truss are omitted, the roof material can be installed diagonally on both sides of the space truss, and the area found from the ground Can be reduced.

Embodiment An embodiment of the present invention will be described below in detail with reference to the drawings.

1 and 2 are a rooftop plan view and a side sectional view of a building provided with an atrium having a retractable space truss roof according to the present invention, and FIG. 3 is an enlarged sectional view near an end portion of the atrium roof. .

An atrium 4 having a substantially square cross section is provided in the center of the building 1 in a range from the ground 2 to the roof. The roof 5 of the atrium 4 is a steel truss 6 and a glass roofing material 7
And is divided into two parts at the center line, each of which moves in a direction perpendicular to the parting line and has an open position overlaid on the roof of the building 1 and a closed position where the opening of the atrium 4 is closed. It is possible to move between.

As a traveling device for moving the atrium roof 5, rails 8 are laid on both sides of the atrium opening and on its extension line, and a suitable number of wheels 9 are correspondingly provided at the end of the steel truss 6 of the atrium roof. Installed. As shown in FIG. 3, a hook 10a is provided at the lower end of the bracket 10 for mounting the wheel 9 on the steel frame truss 6 to hold the upper flange of the rail 8 from both sides and prevent it from rising.

Guide rails 11 are attached to both sides of the openable-closable atrium roof 5 along the entire length thereof, and correspondingly, on the roof 3 of the building 1, an appropriate space is provided over the entire moving range of the atrium roof 5. The guide roller 12 is attached to a guide roller receiving column 13 which is erected on the roof. The atrium roof 5 is fixed to the rail 8 by escape prevention pins 18 at both open and closed positions.

Now, in this embodiment, as shown in FIG. 1 and FIG.
Each wheel train on each side of each of the two atrium roofs is provided with four wheels. As shown in FIG. 4, each wheel is generally arranged at each intersection of the lower chord member and the lattice member of the truss. Of course, the number of wheels varies depending on the size of the atrium. In the case of an atrium with a side of about 30 m, there are 7 sides on each side for the atrium roof divided into two parts.
It is also possible to provide individual wheels.

As shown in FIGS. 2 and 3, the vertical transformer on the wheel train and the end of the upper chord member connected to the upper contact of the vertical truss are omitted, and the roof member 15 on the end face of the truss is attached obliquely. ing.

As described above, by omitting the vertical truss on the wheel train and the end of the upper chord member connected to the upper contact of the vertical truss, the rigidity of the truss in the wheel train direction becomes small, and the rail 8 has irregularities. Also, even if there are variations in the size and mounting position of each wheel 9, the truss flexes and easily follows,
An even load is applied to each wheel, and the cross-sectional dimensions of the rail 8 and the diameter of the wheel 9 can be reduced.

Further, since the roofing material 15 is attached obliquely, it is possible to reduce the found area.

In the case of the present embodiment, the lateral guide during traveling for opening and closing the atrium roof is not performed by the rail 8 but by the guide rail 11 and the plurality of guide rollers 12, so that each wheel 9 is slightly disjointed. It is preferable to apply a slip agent to the treads of the wheels 9 and the rails 8 so that the vehicle can travel smoothly with less running resistance even when the vehicle is leaning obliquely.

Effects As described above, according to the present invention, the number of wheels that support the atrium roof for traveling is increased, and the end portions of the upper chord members connected to the vertical transformers and the upper contacts of the vertical trusses on the wheel trains are increased. By omitting, the load can be evenly distributed by weakening the rigidity of the roof truss where the wheel train is attached, the height to the top of the atrium roof can be reduced, and both sides of the space truss can be reduced. The installation area can be reduced in combination with the installation of the roof material on the surface at an angle. Also, the dimensions of rails and wheels are reduced,
Since the roof structure is small, the weight of the structure can be reduced, and the cost can be reduced.
