Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for supporting a roof of a building, and can be applied to a roof of a building having columns and beams, for example, a unit construction method or a conventional frame construction method.

[0002]

BACKGROUND ART In a unit type building constructed by combining a plurality of building units produced in a factory at a construction site, a roof is composed of a plurality of roof panels, and the roof panels are provided on the building unit. Also, a building is being constructed so that it is supported by a roof support member such as a roof panel support bracket. Conventionally, these roof support members have been arranged on a pillar which is a frame material of a building unit so that the roof load acting on the roof support member can be supported by this pillar.

[0003]

However, there are roofs in which a plurality of roof panels, which are roof constituent members, are complicatedly combined in order to improve designability, and in such a roof, all roof support members are used. Members cannot always be placed on the pillars that are spaced in the building unit based on the prescribed module size, and some roof support members are placed on the upper beams that are bridged between the pillars of the building unit. There are cases where you must do it. Since the roof support member thus arranged on the upper beam is not provided on the pillar, the roof load acting on this roof support member is supported by the upper beam, and therefore, There is a possibility that the beam will be bent and deformed downward and the roof load cannot be effectively supported.

Such a problem also occurs in a conventional frame structure building in which the frame of the entire building includes a plurality of columns and beams bridged between the columns.

It is an object of the present invention to provide a roof support structure which is capable of effectively supporting a roof load even if there is a roof support member arranged on the beam and not provided on the pillar. There is a place to do it.

[0006]

A roof support structure according to the present invention is arranged on a first roof support member arranged on a pillar of a building and on a beam spanned between the pillars. Therefore, it is configured to include a second roof support member that is not provided on the pillar, the building is configured with a plurality of building units,
The pillars are the pillars of this building unit, and the beams are
Of the object unit, the first and second roof support members support the roof constituent members, and the first roof support member and the second roof support member are on the first roof support member side. The first roof support is connected to the first roof support
The holding member is a bundle .

In the above, the first roof support member may be provided only on one side of the second roof support member, and the second roof support member may be provided.
The first roof support member may be provided on both sides of the roof support member of the above, and when the first roof support member is provided on both sides of the second roof support member as described above, both first roof support members are provided. The support member and the second roof support member are connected by the traction member.

[0008]

Further, the roof constituent member supported by the first and second roof supporting members may be a roof panel produced in a factory and transported to a building construction site, and a roof plate for forming a roof. The roof according to the present invention may be a panel construction method or a conventional construction method.

[0010]

According to the present invention, since the first roof support member and the second roof support member are connected to each other by the pulling member inclined upward on the first roof support member side, the second roof support member is connected. The roof load acting on the first roof support member is transmitted to the first roof support member by the traction member, and a traction force of an upslope along the traction member acts on the traction member, and the traction force disposes the second roof support member. The roof load acting on the fixed beam is reduced, and the roof load can be effectively supported.

There is a first roof support member on both sides of the second roof support member, and both the first roof support member and the second roof support member are provided.
When the roof supporting member of is connected by a traction member, the traction force acting on the two traction members can further reduce the roof load acting on the beam, and the horizontal component of the traction force of these traction members is Since they cancel each other, it is possible to prevent the building from being deformed by the horizontal component.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a main part of a building 1 to which a roof support structure according to the present embodiment is applied, and this building 1 is a unit-type building in which a plurality of building units 2 are combined in the front, back, left, right, and top and bottom. As shown in FIGS. 2 and 3, the framework of each building unit 2 includes four pillars 3 at four corners, and four upper beams 4 bridged between the upper ends of these pillars 3, It is configured to include four lower beams 5 bridged between the lower ends of the columns 3.

As shown in FIG. 1, the roof 7 provided above the lower building unit 2A and the entrance unit 6 of the building unit 2 includes a plurality of roof panels produced in a factory and transported to a building construction site. 8 are combined, and these roof panels 8 are roof constituent members. Each roof panel 8 is adapted to be supported by the bundles 9 to 12 and the roof panel receiving brackets 13 to 24 provided on the upper surfaces of the shed building unit 2A and the entrance cover unit 6, and the bundles 9 to 12 are The placing members 25 are provided via the arms or directly, and the placing members 25 and the roof panels 8 placed on the brackets 13 to 24 are fastened by fasteners such as bolts to bundles 9 to 12 and the brackets. 13-
It is designed to be attached to 24.

The bundles 9-12 and the brackets 13-24 comprise base plates 26, which
6 is attached to the upper surface of the shed building unit 2A and the entrance cover unit 6 with fasteners such as bolts.

As shown in FIG. 2, the bundles 9 and 12 are arranged on the pillars 3 of the shed building unit 2A, and the bundle 11 and the roof panel receiving bracket 20 are arranged on the upper beam 4 spanned between the pillars 3. Are placed on top of. That is, these bundles 11
The roof panel receiving bracket 20 is not arranged on the pillar 3, and in this embodiment, the bundles 9 and 12 are the first roof supporting members, and the bundle 11 and the roof panel receiving bracket 20 are the second roof supporting members. Has become a roof support member.

The bundle 9 and the bundle 11 are connected by a pulling member 27,
The pulling member 27 is inclined upward on the bundle 9 side.
Further, the bundle 12 and the bracket 20 are connected by a pulling member 28, and the pulling member 28 is inclined toward the bundle 12 at an upward slope. In this embodiment, these pulling members 27 and 28, which are braces, are turn buckles, and their lengths are adjustable.

FIG. 3 is a view showing the action of the roof load in the portions of the bundles 9 and 11 connected by the traction member 27. In each building unit 2, only the framework of the pillar 3, the upper beam 4 and the lower beam 5 is shown. ing. The roof load, in other words the load on the roof panel 8, is supported by the bundles 9 and 11, the roof panel support bracket 17,
Since the bundle 9 and the bracket 17 are arranged on the pillar 3, the load of the roof panel 8 acting on these pillars 9 and 17 is transmitted to and supported by the pillar 3. On the other hand, since the bundle 11 is arranged on the upper beam 4 spanned between the upper ends of the columns 3, and there is no column 3 below it, the load W of the roof panel 8 acting on the bundle 11 is equal to that of the upper beam 4. It becomes a bending load.

However, in this embodiment, since the bundle 11 is connected to the bundle 9 by the pulling member 27 that is inclined upward on the bundle 9 side, the pulling force (tensile force) F due to the load W is applied to the pulling member 27. Occurs and the vertical component F _{1 of} this traction force F acts to lift the bundle 11 and the upper beam 4, thus
The upper beam 4 can be prevented from being curved and deformed downward, and the load W can be effectively supported.

Further, in this embodiment, since the pulling member 27 is a turnbuckle whose length is freely adjustable, when the pulling member 27 is bridged between the bundles 9 and 11, an appropriate tension force can be given, As a result, when the load W is generated, the traction force F having the vertical component F ₁ with respect to the load W can be generated before the upper beam 4 is largely deformed downward.

The effective support of the roof load described above is also performed at the location of the bundle 12 and the bracket 20 which are connected by the pulling member 28 shown in FIGS.

FIG. 4 shows another embodiment of the present invention. This Figure 4
Then, the members having the same functions as those in the above-mentioned embodiment are designated by the same reference numerals. In the above embodiment, the bundle 9 which is the first roof support member arranged on the pillar 3 is the second roof support member arranged on the upper beam 4.
In this embodiment, the bundles 9 are located on both sides of the bundle 11, and both bundles 9 and 11 are inclined upward to the bundle 9 side. They are connected by a pulling member 27.

[0022] According to this, the bundle 11 and the load W of the roof panels 8 which acts on the upper beam 4 can be more effectively supported by 'vertical component F' ₁ tractive force F occurring two traction members 27 At the same time, the horizontal components F ′ ₂ of the pulling force F ′ of the pulling members 27 are opposite to each other, and these components F ′ ₂ are offset. Therefore, bundle 1
The load in the horizontal direction does not act on 1, and the bundle 11 and the building unit 2 can be prevented from being deformed by the load in the horizontal direction.
