Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an openable and closable temporary roof which can be used as a rain shelter for a material storage area such as a construction site or a work place such as an opening, and more particularly to an automatic closing or shielding area by a roof. Is to be easily changed.

[0002]

2. Description of the Related Art In construction and civil engineering work sites, temporary roofs are provided in whole or in part of a work place to prevent strong sunlight in summer, to prevent cold in winter, or to prevent sudden rain. ing. By providing a temporary roof, the work can be performed in a stable environment with little influence of the weather and the like.

[0003] For example, during work such as painting and welding, and curing of concrete, a temporary roof is provided so as to prevent wind, rain, dust and the like from being blown and to improve construction quality.

[0004] In addition, in the reverse striking method in which a floor portion of the first floor is constructed first, and then excavation work and skeleton construction of an underground portion are performed, a slab opening installed for excavation work and loading and unloading of materials. In addition, a temporary roof is provided to prevent rain from entering the work area.

[0005] Further, a temporary roof is also provided above the material storage area or the material processing place in order to prevent the material from being wet due to unexpected rain or to interrupt the work.

[0006] A temporary roof is also provided at the material entrance so that unloading from a truck is not affected by rain.

[0007] As such temporary roofs provided at various places in a construction site, there are various movable roofs in addition to fixed roofs such as an air film mechanism and a beam mechanism. On a movable roof, for example,
Various configurations have been proposed, such as a method in which the roof can be opened and closed, a method in which the roof itself moves horizontally, and a method in which the entire roof moves vertically in accordance with the progress of construction.

[0008]

Most openable roofs among the above-mentioned conventional movable roofs have a structure in which a sheet member is stretched over a plurality of beam members and the beam members are moved along guide rails. Are opened and closed like a bellows. When opening and closing, an electric winch or an electric trolley is used, and since it has a device configuration that acts on opening and closing of the roof, the opening and closing mechanism becomes complicated, and the price increases accordingly.

[0009] In many cases, a sufficient power supply cannot be obtained in a site, and in a small-scale site, manual operation is often sufficient. There is also a need for an inexpensive openable temporary roof that can be manually opened and closed with a simple configuration.

On the other hand, when opening and closing is performed by a manual winch or the like, it is necessary to rotate the handle of the manual winch to wind up or down each time opening and closing.
In particular, for a large-scale temporary roof, such manual work requires a considerable amount of labor, which is difficult. Therefore, it is necessary to devise a device that can easily perform such opening and closing work.

If the above manual work can be avoided in any of the opening and closing work, the on-site work becomes easier. The inventor of the present invention focuses on the urgency of opening and closing the roof members when the roof is closed due to sudden rain or the like, and it is necessary to develop a means for automatically closing the roof. I thought.

Further, in the conventional temporary roof, the covering area of the roof can be adjusted by appropriately adjusting the expansion and contraction state of the sheet in the direction along the guide rail, but it is orthogonal to the guide rail direction. It was not easy to change the roof covering area in any direction. In order to be able to respond to various construction sites, we thought that technical development of such points was also necessary.

[0013] In addition, in the case of a conventional temporary roof with a sheet member, rainwater tends to accumulate in the slack on the tent sheet. For this reason, there is a configuration in which an inclination is provided in the front and rear direction along the opening and closing direction so that rainwater flows down.

However, the elasticity of the sheet member itself is inevitable. Even if the sheet member is stretched with a strong tension, some slack occurs, and it is inevitable that rainwater accumulates in the slack portion. It is conceivable that the sheet member is stretched with considerable tension so as not to cause any loosening, but the sheet member and beam member require unprecedented strength, and it is necessary to review the strength of the member itself, and it is available now. It is unlikely to be a practical solution based on the use of members.

Further, if rainwater accumulates in a state where the sheet member is compressed in a bellows shape, if the roof is temporarily installed by extending the sheet member without knowing that, the accumulated rainwater will flow at a stretch and the worker or material However, inconveniences such as the above may occur. Temporary roofs are used in outdoor construction sites, and so the elimination of this point is strongly demanded from the sites.

An object of the present invention is to make it possible to automatically close a roof with a retractable temporary roof.

Another object of the present invention is to provide a retractable temporary roof,
An object of the present invention is to make it possible to easily change a roof covering area in a direction orthogonal to a roof opening / closing direction.

Another object of the present invention is to provide an openable temporary roof,
The purpose of this is to make it easier for rainwater on the roof to flow.

The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

[0020]

SUMMARY OF THE INVENTION Among the inventions disclosed in the present application, the outline of a representative one will be briefly described.
It is as follows.

That is, according to the present invention, two guides which are respectively inclined above the work place and which are attached in parallel with each other have both ends along the guides at the upper end side and the lower end side of the guide. And a plurality of movable beams movably mounted between the movable beams.

The movable beam is fixed to the inclined upper end of the guide and is attached to each of the movable beams, and the respective movable beams are arranged at predetermined intervals along the guide by the weight of the movable beam. A sheet member for shielding the work place is provided in a state where the sheet member is located at the position.

[0023] Further, the tip of a pulling member such as a pulling rope provided with a pulling end portion on the inclined upper end side of the guide is fixed to the lowermost moving beam of the plurality of moving beams, and this pulling member is driven by driving means. To be able to tow. Each of the movable beams is pulled toward the inclined upper end of the guide against its own weight, and the temporary roof is fully opened by folding the sheet member.

When the traction member is released from the traction, the movable beam moves toward the inclined lower end of the guide by its own weight to bring the seat member into a fully closed state.

In particular, if the traction member is provided along the sheet surface of the sheet member, for example, compared to a case where traction members are provided at both ends of the moving beam and the moving means is used, the traction member is pulled.
The length of the traction member can be reduced.

Further, since the sheet member can be opened by towing the traction member toward the upper end of the slope by the driving means, the traction member does not have to cross the opening at the time of opening, and when the material is carried in from above by a crane or the like. Does not hinder.
The degree of opening of the seat member can be adjusted by adjusting the degree of traction of the traction member.

Further, if the movable beam is formed as a pipe member which is slidably fitted, the length of the movable beam can be adjusted by adjusting the degree of fitting, and the seat member adapted to the movable beam can be adjusted. The roof width can be easily adjusted according to the temporary work place.

If the heights of the two guides provided at an angle are different from each other, the roof surface of the sheet member provided between the two guides in the manner described above is perpendicular to the plane of the roof surface. 2
Each becomes an inclined surface in the axial direction. Since the sheet member is also inclined in a direction orthogonal to the guide direction, rainwater from the sheet member surface easily flows.

If the sheet is inclined only in the guide direction, a slack portion is formed in the sheet member stretched between the movable beams, and the rainwater easily accumulates there. Can be prevented.

Alternatively, when forming the sheet member, if the sheet members are stretched by inclining the adjacent moving beams (in such a manner that the moving beams are not parallel to each other), the slack of the sheet member between the moving beams can be obtained. Since the portion is inclined in a direction intersecting the guide direction, it is possible to prevent rainwater from collecting.

That is, if the sheet member is stretched in a state where the adjacent moving beams are inclined with respect to each other, the tension length of the sheet member is different between both ends of the moving beam.
When the tension is longer, the slack portion of the sheet member is formed deeper than when the tension is shorter on the other side, and the slack portion is inclined.

[0032]

a, 10b, 10c, and 10d are provided, respectively.

A guide 20 is provided between the pillars 10a and 10b with a guide 11 inclined via a spar 11 in the same manner as in the first embodiment. A guide 20 is also provided between the columns 10c and 10d with a guide 11 interposed therebetween. The two guides 20 are attached to the columns 10a to 10d such that the heights thereof are different from each other, that is, the guides 20 are parallel to each other.

In the present embodiment, the fixed beam 40 is also moved from the support 10 a to the support 10 in accordance with the level difference between the two guides 20.
It is provided to be inclined toward d. The support 10

2 may be connected to the guide 20 and the clamp 13 via the spar 11 in the same manner as in the first embodiment.

The sheet member 30 is also configured in the same manner as in the first embodiment, and includes a plurality of moving beams 31 provided in parallel with each other.
Sheet material is stretched between them. The procedure for attaching the sheet member 30 to the guide 20 is the same as in the first embodiment.

The driving means 50 is also provided in the first embodiment.
It is configured similarly to. The temporary roof B thus constructed can be opened by opening the traction member 54 with the hoisting handle 53 of the driving means 50 and stopping it by the stopper in that state.

When the stopper of the hoisting handle 53 is released, the movable beam 31b of the sheet member 30 naturally moves toward the lower end of the inclination along the guide 20 by its own weight, and the sheet member 30 is naturally deployed. The roof is completely closed.

On the other hand, the temporary roof B of the present embodiment differs from the temporary roof A of the above embodiment in that the
Since it is also inclined in the direction perpendicular to the developing direction, there is no fear that rainwater or the like will accumulate in the slack portion of the sheet member 30 between the movable beams 31.

(Embodiment 3) In the present embodiment, in the temporary roof C having the same structure as that of the first embodiment, the adjacent moving beams 31 that stretch the sheet member 30 are inclined with respect to each other (ie, adjacent to each other). The configuration provided so that the movable beams 31 are not parallel to each other will be described below.

In the present embodiment, as shown in FIG. 9, similarly to the first embodiment, guides 20 are provided on the support 10 and the intermediate support 12 so as to be inclined in parallel with each other.

On the other hand, the sheet member 30 includes a plurality of movable beams 3

The plurality of moving beams 31 between 1b are provided to be inclined so as not to be parallel to each other.

The intermediate moving beam 31 is, as shown in FIG.
The tension length of the sheet members 30 at both ends of the moving beam 31 is configured to be repeated long and short. Further, on both ends of the moving beam 31, the length of the opposite side is set to be opposite.

On the other hand, the driving means 50 is provided in the first embodiment.
Is provided on the fixed beam 40 side, and the
By winding the 4 up with the hoisting handle 53, the movable beam 31b can be pulled up to the inclined upper end side to open the roof.

When the moving beam 31b is pulled up by the driving means 50, as shown in FIG.
Between 1, the sheet member 30 is loosened. The slack portion X is more deeply loosened when the sheet member 30 has a longer tension length than when the sheet member 30 has a shorter tension length. Therefore, the valley line W connecting the valley portions of the slack portion X is inclined, and the rainwater easily flows in the slack portion X.

With this configuration, unlike the second embodiment, the rainwater can be actively removed by slightly closing and adjusting the sheet member 30 without making the two special guides parallel to each other. Can be shed.

Even when the seat is not closed or adjusted, that is, even when the roof is in the fully closed state, some slack occurs between the movable beams 31 due to the rainwater falling on the sheet member 30, but such a slight slack occurs. But as above, valley line W
Is inclined, so that rainwater flows easily unlike the case where the movable beam 31 is provided in parallel.

Further, as described above, the tension of the sheet members 30 at both ends of the movable beam 31 is repeatedly set to be long and short, and is configured to be reversed on the opposite side, so that the slack portion that can be closed can be provided. The inclination of the valley line W of X is formed alternately on the left and right. The rainwater accumulated on the roof is also drained to the left and right sides of the temporary roof C in accordance with that, and there is no fear that the rainwater will only accumulate on one ground side of the temporary roof, for example.

As described above, the invention made by the present inventor has been specifically described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and can be variously modified without departing from the gist thereof. Needless to say, there is.
