[Industrial applications]

 The present invention relates to a temporary roof structure for all-weather construction that covers the upper part of the building when constructing an RC structure and enables construction without being affected by the weather.

[0002]

[Prior Art]

 Many construction works are affected by the weather such as rainfall, snowfall, heat, and cold. Especially, in the RC structure work, it is necessary to suspend the work during rain or snow, which is a major cause of delay in construction period. ..

For this reason, overtime work and holiday work increase, making it difficult to establish a two-day work week, which is one of the major causes for the youth to leave the construction industry.

Therefore, in order to improve the working environment of construction work in recent years, a proposal of a temporary roof has been proposed in which the upper part of the skeleton is covered with a roof so that construction can be performed even during rainfall and the severe working environment in summer and winter is alleviated. Has been done.

[Problems to be solved by the device]

 By the way, in the above-mentioned temporary roof, an electric climbing device is attached to the pillars erected around the skeleton, the roof covering the skeleton is fixed to the climbing device, and the roof is climbed with the climbing device as the skeleton work progresses. Since it is designed to raise the roof, the equipment cost is high, and it is difficult to raise the roof in synchronization with each climbing device, which makes it difficult to raise the roof smoothly. There is.

In view of this, the present invention focuses on the fact that almost all cranes are used in the construction of RC structures, and by using the crane to raise the roof, the roof can be raised smoothly and the structure can be improved. The challenge is to provide a temporary roof structure for all-weather construction that can be simplified and the cost of equipment can be reduced.

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a plurality of struts standing at an outer position surrounding a skeleton to be constructed at predetermined intervals, and a plurality of roofs covering the upper part of the skeleton are adjacent to each other. It has a structure in which at least one roof can be opened and closed by fixing it to the columns so that they can be detached from each other, with the height difference between the roofs being set independently.

[0008]

[Action]

 The roof that covers the upper part of the skeleton is detachably attached to the pillars that stand upright to surround the outside of the skeleton to be constructed, improve the environment of the skeleton construction part, and enable construction even in the case of rain to shorten the construction period. ..

[0009] Every time the construction of the frame progresses, the roof is hung by a crane, the part fixed to the pillar is removed, and then the roof is pulled up by the required stroke in order from the taller roof, and then the pillar is fixed again. Repeat.

In addition, when the material is loaded from the upper part of the skeleton part, the openable roof is opened and the material is loaded from this part.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a large number of struts 1 are erected on the outside of the RC skeleton A to be constructed and at both sides of the skeleton A. The columns 1 are incorporated in the same row as the external scaffolds 2 that are temporarily installed so as to surround the outside of the frame A, and are arranged at regular intervals in the length direction of the frame 1.

The roof covering the upper part of the skeleton A is independent for each span of each strut 1, and the four corners are detachably fixed to the strut 1 to cover the skeleton A and the upper roof 3 and the same four corners. 1 and a lower roof 4 which is fixed so as to be detachably fixed to cover the upper part of the structure A and which is provided at a position slightly lower than the upper roof 3, and these are alternately arranged in the longitudinal direction of the structure A. It covers the entire surface of A.

The upper roof 3 is a sheet having an upper surface of a frame 8 in which a pair of beam members 6, 6 whose both ends are fixed to the columns 1 on both sides via a mounting mechanism 5 are connected by a plurality of horizontal rails 7 and which has been subjected to a disaster prevention process. 9 is stretched and the structure has a downward slope on both sides from the central ridge.

Similarly, in the lower roof 4, a seat 13 is stretched on a frame 12 in which a pair of beam members 10 and 10 whose both ends are fixed to a support 1 via a mounting mechanism 5 are connected by a plurality of horizontal rails 11. However, it has a structure with a downward slope on both sides from the central ridge.

As shown in FIG. 5, the side edge of the upper roof 3 facing the lower roof 4 is supported by an arm 14 fixed to the beam member 6 to provide an extension 9a of the seat 9, and the extension 9a is a lower portion. It is designed to be wrapped on the roof 4.

In the case shown in the figure, the lower roof 4 holds the sheet 13 with a cross rail 11 so that it can be folded and stretched in a zigzag shape in the length direction of the skeleton A. The sheet 15 can be opened and closed manually or electrically with a wire 15 stretched over the upper part of the roof, and by opening the upper roof 3, the material can be taken in and out of the frame A from this part.

The above-mentioned attachment mechanisms 5 for fixing the upper and lower roofs 3 and 4 to the pillar 1 are the same, and as shown in FIG. 4 for the case of the lower roof 4, the angle member 1a that constitutes the pillar 1 is attached. A mounting hole 16 is provided, and the angle member 1a and a bracket 17 fixed to the end of the beam member 10 are detachably coupled with a plurality of bolts 18, and the brackets 17 are spaced at intervals of the mounting holes 16 by tightening and loosening the bolts 18. The fixed position of the can be changed upwards.

The mounting mechanism 5 is not limited to the one shown in the figure. For example, a pin-placing type mountable bracket 5 can be removably fixed to the column 1, and the vertical position of the bracket 17 can be adjusted. 17 may be tightly connected to the column 1 so that the end of the beam 10 can be detachably fixed.

The temporary roof structure of the present invention has the above-described structure, and the outer scaffold 2 and the pillars 1 are assembled around the portion where the RC structure A is constructed, and the upper part of each span is set on the ground. And the lower roofs 3 and 4 are assembled.

Next, using the crane B, first, the lower roof 4 is hoisted, and the lower roof 4 is erected at a desired height position between the corresponding columns 1, and both ends of the beam member 10 are fixed to the columns 1 by the attachment mechanism 5.

After that, the upper roof 3 is hoisted by the crane B and installed between the corresponding columns 1, and both ends of the beam member 6 are fixed to the columns 1 by the attachment mechanism 5.

As shown in FIG. 5, the extension 3a of the upper roof 3 faces the lower roof 4, and the upper and lower chamber roots 3 and 4 are sequentially installed to cover the entire upper surface of the skeleton A. Therefore, it is possible to carry out the construction of the frame A even when it is raining, and it is possible to improve the working environment in the summer and winter.

In FIG. 5, the gap H between the upper roof 3 and the lower roof 4 is set to be wide in the summer and narrow in the winter to relax the working environment.

Further, when the material is taken into the skeleton A, the sheet 13 on the lower roof 4 at a desired position may be folded and opened, and the material may be carried in by a crane from the opening portion.

When the skeleton A becomes higher due to the construction, after the outer scaffold 2 and the pillar 1 are added upward to assemble, first, as shown in FIG. 1, the upper roof 3 is hung by the crane B, and the mounting mechanism 5 The upper roof 3 is lifted up by a predetermined floor height, and the four corners are fixed to the pillar 1.

Thereafter, the lower roof 4 is also similarly lifted by the crane B and fixed to the pillar 1, and the construction of the frame A is performed. Every time the frame A is constructed by a predetermined floor height, the external scaffold 2 Repeating the addition of the pillar 1 and pulling up the upper and lower roofs 3 and 4, after the completion of the skeleton A, the upper and lower roofs 3 and 4 are removed. The dismantling of the outer scaffold 2 and the pillar 1 is performed after finishing the outer wall as usual.
