For example, a U-shaped cross-section mold member is fixed with its open faces facing each other, and Not only can the wheels 5 stored in the vehicle run, but also the upward movement of the wheels 5, that is, the lifting of the temporary roof unit 6 can be suppressed, and
The thrust load of 1 may be received by the side surface of the rail 4.

Next, the temporary roof unit 6 movable horizontally along the rail 4 will be described. FIG. 4 is a front view, a side view, and a sectional view showing a temporary roof unit 6 which is an embodiment of the invention described in claim 1. In this temporary roof unit 6, two arch members 16 made of steel are arranged substantially parallel to each other, and these arch members 16 are connected and fixed by a lateral member 17 at intervals to form a frame structure 18. A film material 19 is stretched between the arch members 16, and a flexible tension member 20 is stretched in the span direction of the arch member 16 so as to abut against the film material 19 from above at a substantially central portion between the arch members. Is pulled downward to introduce tension into the film material.

The frame structure 18 of the temporary roof unit 6 is
In this embodiment, a pair of arch members 16 each having a U-shaped cross section are arranged in parallel with a predetermined distance, for example, a distance of 6 meters, with the open surfaces facing inward.
As shown in FIG. 5, leg portions 21 that are bent downward are provided at both ends of 6. Both legs 21 of two arch members
6, the horizontal member 22 provided between the lower ends and the horizontal member 22 are joined at approximately the center, and the leg 2

In addition, since the curved piece 25 on the way has a constant curvature, it can be diverted. Therefore, the number of bending pieces 25 and the end members 26 are appropriately selected and the frame structure 1 is not required to make the arch member 16 according to the size or width of the construction yard Y at the construction site each time.
8 can be assembled, and the operation efficiency of each member can be improved.

In order to stretch the film member 19 on the frame structure 18 having such a structure, the edge of the film member 19 along the arch member is fixed to the pin 27 of the arch member 16 and the arch member of the arch member is fixed. The end of the span direction is the pin 27 of the lateral member 17.
Further, a tension tape as a flexible tension member 20 is stretched from about the upper surface to approximately the center of the film material 19 in a state in which a tension force is applied, and the tape ends are fastened to the lateral members 17 on both sides. Then, the tension in the width direction is introduced into the film material 19 by the tension of the tension tape. It should be noted that when the end members having different lengths are selected and connected, the range in which the film material 19 is stretched also changes. In this case, the film material 19 may be divided and stretched so as to partially overlap each other. . That is, as shown in FIG. 7, the central film material 19 a stretched between the curved pieces 25 and the end member 26.

Therefore, at the time of rainfall, rainwater does not flow on the V-shaped bottom and stay on the membrane material 19 or flow down from the arch member 16 side to the construction yard Y, and is guided to the lateral member 17 side for wastewater treatment. It Further, when the tension is applied to the film material 19 in this manner, the film material 1
9 is always maintained in a state of being pushed down by the pulling member 20, so that the film material 1 is not affected by strong wind.
It is possible to effectively prevent the 9 from being violently moved. Therefore, even if it receives a strong wind, it is not easily damaged.

The film material 19 is a waterproof and durable sheet, and it is desirable that light can pass through it appropriately, and a known material such as canvas or fiber reinforced vinyl sheet may be used. The tension member 20 that applies tension to the film material 19 is not limited to the tension tape, and may be a long material having flexibility, such as a wire or a sturdy string.

In the temporary roof unit of the above-described embodiment, the frame structure 18 is formed by connecting and fixing the ends of two arch members 16 to each other by the lateral member 17. Is not limited to those using
The width may be increased by increasing the number of arch members 16 arranged in parallel. In this case, the tension members 20 that apply tension to the film material 19 may be stretched at substantially the center between the adjacent arch members 16, and the plurality of tension members 20 may be stretched on one temporary roof unit 6. .

FIG. 8 is a front view, a side view, and a sectional view showing a temporary roof unit which is an embodiment of the invention described in claim 2. In this temporary roof unit 56, two arch members 66 made of steel are arranged substantially in parallel, and an auxiliary arch member 71 is arranged substantially parallel between these arch members. The auxiliary arch member 71 is arranged at a higher position than the arch member 66, and the arch member 66 and the auxiliary arch member 71 are connected and fixed to each other by a lateral member 67 with a space therebetween, thereby forming a frame structure. Is configured.
A film material 69 is stretched between the arch members,
A flexible tension member 70 is stretched in the arch span direction between the auxiliary arch member 71 and the auxiliary arch member 71, abuts against the film material 69 and pulls the film material 69 downward, and introduces tension in the inter-arch member direction into the film material 69. is doing.

The frame structure of the temporary roof unit 56 is almost the same as the frame structure used in the temporary roof unit 6 shown in FIG. 4, and the frame structure used in the temporary roof unit of this embodiment. In the body, an auxiliary arch member 71 is added and supported by the lateral member 67. The film material 69 is stretched so as to cover the auxiliary arch member 71, and the edge along the arch member 66 is fixed to the pin 77 provided on the arch member 66. Two tension members are arranged on both sides of the auxiliary arch member 71, and each tension member is fixed to the lateral member 67 in a state where tension is introduced. In such a temporary roof unit 56, the membrane material 70 is stretched in an inverted V shape to prevent the flag from being vigorously flagged by wind, and rainwater is collected and flows down to the arch members on both sides.

Next, a temporary roof which is an embodiment of the invention described in claim 4 will be described. This temporary roof is shown in Figure 9.
And as shown in FIG.
a, the inner rail 4b is double-laid, and a plurality of concave temporary roof units 6 shown in FIG. 4 are placed on the inner rail, and the outer rail has a size capable of covering the concave temporary roof unit 6. 8 is provided with the convex temporary roof unit 56 shown in FIG. And FIG.
As shown in (a), a plurality of concave temporary roof units 6
And one convex temporary roof unit 56 are arranged so as to cover the entire construction yard Y. Further, the rail 4 is provided only for the entire length of the construction yard, that is, in the range L where it is necessary to cover the upper part with the temporary roof. In such a temporary roof, since the concave temporary roof unit 6 can be stacked below the convex temporary roof unit 56, the concave temporary roof unit 6 or the convex temporary roof unit 56 can be moved in the horizontal direction to construct the construction yard Y. The upper side can be opened at any position.

For example, as shown in FIG. 11 (b), when it is desired to open a part of the construction yard, the convex temporary roof unit 56 and the adjacent concave temporary roof unit 6b are moved to move the convex temporary roof unit. By stacking with 56, the upper part of the construction yard can be opened. In addition, FIG.
As shown in (a), the convex temporary roof unit 56 may be moved and opened. Further, the other concave temporary roof units 6a, 6c, 6d can be sequentially moved to open an arbitrary portion, or the temporary roof units can be arranged at a small interval as shown in FIG. 12 (b). It is also possible to open multiple parts.

Next, a method of constructing the temporary roof shown in FIG. 1 will be described. This construction method is a process of assembling the temporary support columns 2 on both sides of the construction yard Y, and a bracket 3 is fixedly attached to the temporary support columns 2 in a detachable state, and a rail 4 is laid while being supported by the brackets 3. A step of arranging two arch members 16 made of steel material substantially in parallel, and connecting and fixing these arch members 16 with a lateral member 17 to form a skeleton structure 18, and the arch member 1
A step of tensioning the membrane material 19 between the six and tensioning the membrane material 19 by stretching the flexible tension member 20 in the span direction of the arch member 16 and the wheel 5 provided on the frame structure 18 The step of placing on the rail 4 and the fastening of the bracket 3 to the temporary strut 2 are loosened, the temporary roof unit 6, the rail 4 and the bracket 3 are integrally lifted to adjust the height, and the bracket 3 is fixed to the temporary strut 2. It consists of the height changing process of fixing again.

That is, the temporary support columns 2 are assembled according to the width of the construction yard Y, and necessary reinforcement is applied. Next, the brackets 3 are fixedly attached to the temporary support columns 2 with the same height (the height corresponding to the initial height of the temporary roof unit 6), and the rails 4 are mounted on the brackets 3. Then, the winch 7 is installed below the temporary support column 2. The curved piece 25 and the end member 26 are selected according to the width of the construction yard Y, and these are bolted to form the arch member 16. Between such two arch members 16, a lateral member 17
Are fastened by bolts to assemble the frame structure 18, and the film material 19 and the tension tape are stretched on the frame structure 18. Then, the temporary roof unit 6 is lifted and the wheels 5 are placed on the rails 4. Frame structure 1
8, metal fittings, stopper means, etc. for tightly connecting with the rail 4 are used in order to prevent the temporary roof unit 6 from traveling carelessly and derailing due to wind. In addition,
In the above steps, the frame structure 18 may be assembled with the wheels 5 placed on the rails 4.

By covering the construction yard Y with the temporary roof unit 6 in this manner, the construction yard Y and the worker will not get wet with rainwater even in the rain. Therefore, it is possible to continue the construction even if it starts to rain on the way, and it is possible to perform the work such as the placing of slab concrete which could not be performed in the conventional rainy weather without any trouble.

Further, when the construction material is hung by the crane and carried into the construction yard Y, the temporary roof unit 6 becomes an obstacle. In such a case, the stopper means is removed and the temporary roof unit 6 is manually pushed to temporarily install it. The roof unit 6 is moved horizontally along the rail 4. Since the temporary roof unit 6 is lightweight, it can be easily moved manually. When the temporary roof unit 6 is moved manually, compared with the case where it is moved by driving a motor,
Little impact force when stopped.

In this way, when the work at the initial position is completed and the temporary roof unit 6 needs to be raised,
The temporary roof unit 6 is suspended and supported by a wire, the fastening metal fitting 13 of the bracket 3 is loosened, and the winch 7 is operated in this state. The wire for supporting the temporary roof unit 6 is wound around the pulley 8 at the upper end of the temporary support column 2, folded back downward and wound up on the winch. When the winch 7 is operated, the temporary roof unit 6 and the rail 4 are moved. And the bracket 3 are lifted together. Then, when it rises to the next predetermined height, the fixing metal fitting 13 of the bracket 3 is operated to fix it to the temporary support 2. Therefore, by repeating such an operation, the temporary roof unit 6 can be raised as the construction proceeds to the upper floors, and the height can be adjusted to a height suitable for the construction on the upper floors.

Although the embodiment described above is used as a temporary roof at a construction site, the present invention can also be applied to a temporary roof provided in a venue or the like where an event is held.

Since the temporary roof unit is configured, it is possible to reduce the weight of the temporary roof unit and simplify the structure. Therefore, the assembly and disassembly work can be easily performed on site. In addition, because it is lightweight, it can be moved manually when moving the temporary roof unit horizontally, and when adjusting the height, it can be lifted with a simple lifting mechanism such as a small winch, There is no need to use hydraulic equipment that is troublesome to maintain. Further, since the tension member is stretched in the span direction of the arch member to introduce the tension into the film material, it is possible to prevent the film material from violently flagging even when it is blown by a strong wind, and prevent the film material from being damaged. be able to. Further, when the tension member is stretched on the membrane material, the groove is formed in the membrane material, so that the drainage treatment of the rainwater is facilitated and the rainwater can be surely prevented from flowing down to the construction yard Y.

In the temporary roof unit according to claim 2,
Similar to the temporary roof unit according to the first aspect, it is possible to secure sufficient strength with a lightweight and simple structure, and the members can be diverted easily. Further, since tension is introduced into the film material in the direction between the arch members, the film material is prevented from being flagged by wind or the like. Further, this film material has a slope descending from the central portion between the arch members to both sides, and the rainwater is collected near the arch members, which facilitates the treatment of the rainwater.

In the temporary roof according to the third aspect of the invention, since the wheels can travel on the rails supported by the temporary columns via the removable brackets, the temporary roof unit can be easily moved in the horizontal direction. In addition, the bracket, the rail, and the temporary roof unit can be integrated and the height can be easily changed.

In the temporary roof according to the fourth aspect, two types of temporary roof units are used, and these run on different rails and move to a position where the concave temporary roof unit and the convex temporary roof unit overlap. Therefore, the roof can be easily opened at any position without laying a rail extending beyond the range where the temporary roof is provided.

In the method for constructing a temporary roof according to a fifth aspect of the invention, since the temporary roof having the arch member as a supporting frame is supported via the wheels on the rails supported by the temporary columns, the structure is lightweight and simple. A temporary roof can be obtained, handling such as movement is easy, and no trouble occurs even in strong winds.

In the method for constructing the temporary roof according to the sixth aspect, the bracket is loosely attached to the temporary pillar, and the height of the temporary roof unit, the rail and the bracket are integrally lifted to adjust the height. It is possible to easily change the height of the temporary roof many times when constructing a building one by one upwards. Moreover, one set of brackets, rails, etc. are sufficient, and rails are required at each stage. No need to lay.
