Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external covering for covering the periphery of a building construction site, such as a curing sheet and a temporary scaffold.

[0002]

2. Description of the Related Art In recent years, as a method for constructing a building without being affected by wind and rain, as shown in FIG. 7, a frame frame 2 constituting the uppermost floor of a building body 1 to be constructed is previously formed. The construction method is used in which each member is assembled at the construction site 3 below it while pushing it up instead of the roof, and the skeletons are stacked and constructed.

The outer peripheral frame 4 is provided on the lower surface of the perimeter of the frame 2 for the purpose of preventing intrusion of wind and rain into the construction site 3 from the side, scattering of fallen objects, and securing work scaffolding.
Is provided vertically, and a curing sheet 5 is stretched on the outer peripheral surface thereof.

The outer cover 7 constituted by the frame frame 2 and the outer peripheral frame 4 is supported on a temporary mast 8, which is erected on the frame 1.
Then, as the construction of the skeleton 1 progresses, the climbing mechanism 9 provided in the mast 8 climbs it, so that the outer covering body 7 is gradually replenished from the lower side to the upper side.

[0005]

However, the above-mentioned conventional external covering body has the following problems. That is, the outer cover 7 is, as described above,
It is supported by masts 8, 8 which are erected on the body 1. Therefore, when the outer cover 7 is refilled, the load of the entire outer cover 7 must be supported and jacked up by the climbing mechanisms 9 of the masts 8, 8, .... Naturally, the climbing mechanism 9 of the mast 8 must have a jack-up capability for jacking up the load, but naturally the jack-up capability is limited in terms of the size and cost of the mast 8. . On the other hand, if the floor space of the building to be built becomes large,
It goes without saying that the weight of the outer cover 7 and the weight of various equipments such as the hoist 2a provided on the frame 2 also increase accordingly. When the weight exceeds the jack-up ability of the climbing mechanism 9 of the mast 8, the outer cover 7 cannot be refilled.

Of course, this problem can be solved by increasing the number of masts 8 installed, but this directly leads to a significant increase in cost and also causes a problem in construction work. . The present invention has been made in view of the above points, and an object thereof is to provide an external covering that can be automatically refilled even when building a large-scale building. .

[0007]

An outer cover according to the present invention is a frame frame in which an outer cover covering the periphery of a building under construction is installed above a frame of the building through a supporting column. And an outer peripheral frame portion that is vertically attached to a peripheral edge portion of the frame frame portion and is detachably fixed to the frame through a support member. A first climbing mechanism for raising and lowering a frame frame portion is provided, a second climbing mechanism for raising and lowering the outer peripheral frame portion is provided on the support member, and the outer peripheral frame portion is the frame member frame portion. It is characterized in that it is supported by a guide member fixed to the peripheral edge of the so as to be slidable in the vertical direction.

[0008]

In the outer cover of the present invention, the outer cover is hung vertically above the frame and the peripheral frame edge which is installed above the frame through the support columns, and is detachably attached to the frame by the support member. A fixed outer peripheral frame portion is provided, and the support column is provided with a first climbing mechanism for moving up and down the frame frame portion, and the support member is provided with a second climbing mechanism for moving up and down the outer peripheral frame portion. did. The outer peripheral frame portion is supported by a guide member fixed to the frame member so as to be slidable in the vertical direction. Thus, when the frame frame portion is raised by the first climbing mechanism while the outer peripheral frame portion is fixed to the frame by the support member, only the frame frame portion and the guide member are integrally raised. On the other hand, when the outer peripheral frame portion is raised by the second climbing mechanism, the outer peripheral frame portion is raised while sliding along the guide member. In this way, by independently climbing the frame frame portion and the outer peripheral frame portion, the load of the frame frame portion and the outer peripheral frame portion at the time of jacking up can be applied between the first climbing mechanism and the second climbing mechanism. It can be divided and supported.

It is designed to bounce. A roof material 20 is provided on the upper surface of the upper chord member 18 so as to cover the upper part of the construction site 12. Further, on the lower surface of the frame frame 14, a horizontal transfer device 21 such as a hoist for transferring materials and the like at the construction site 12 is provided.

The masts 8, 8, ... Supporting the frame frame 14 are installed at, for example, four positions on the body 11 via bases (not shown), as shown in FIG. Then, each mast 8 (see FIG. 7) is provided with a climbing mechanism (first climbing mechanism) 9, and by operating this, the mast 8 is moved upward by taking a reaction force to the skeleton 11. Can be climbed.

Further, the outer peripheral curing 15 suspended from the lower surface of the frame frame 14 is provided over the entire circumference of the frame 11, as shown in FIG. As shown in FIG. 1 and FIG. 2, the outer peripheral curing member 15 is stretched around the outer peripheral frame (outer peripheral frame portion) 22 having a length of, for example, 20 m in the vertical direction and the outer peripheral surface of the outer peripheral frame 22. The main component is a curing sheet 23 made of, for example, a mesh sheet or a vinyl sheet.

As shown in FIGS. 3 and 4, the outer peripheral frame 22 is composed of a truss-shaped truss frame 24 extending in the vertical direction and a truss member assembled in the horizontal direction, for example, a steel frame or truss. Horizontal member 25,
25, ... are assembled in a side view grid pattern. The truss frames 24 are arranged at regular intervals in the circumferential direction of the skeleton 11 so as to be located in a plane orthogonal to the side surface of the skeleton 11.

As shown in FIGS. 1 and 3, each truss frame 24 has the following structure.
It is provided so that it can slide vertically. That is, on the lower surface of the lower chord member 19 of the frame frame 14, tubular sheaths (guide members) 26, 26 extending in the vertical direction are attached at positions corresponding to the truss frames 24. Inside the tubes 26, 26, there are inner tubes 27, 2
7 is stored so as to be vertically movable. A horizontal beam 28 extending in the horizontal direction is attached to the lower ends of the inner tubes 27, 27, and the truss frames 24, 24, ... Are attached to the horizontal beam 28. In this way, the truss frames 24, 2
, 4 are integrally movable with the inner pipes 27, 27, ..., Horizontal beams 28 in the vertical direction with respect to the sheath pipes 26, 26 ,. . That is, as a result, the outer peripheral frame 22 is supported by the frame frame 14 so as to be slidable in the vertical direction.

As shown in FIG. 1, the outer peripheral frame 22 has, on the side of the frame 11, a guide rail 3 having an I-shaped cross section and having a length of, for example, about three floors of the frame 11 in the vertical direction.
0 is attached.

A support bracket (support member) 31 is provided on the guide rail 30 so as to be slidably supported at two positions above and below a base 31a thereof. The support bracket 31 can be fixed to the guide rail 30 by inserting positioning pins (not shown) into positioning holes (not shown) formed at regular intervals in the guide rail 30.

Arms 31b, 31 extending in the horizontal direction are provided above and below the base 31a of the support bracket 31.
c are rotatably supported in the horizontal plane and foldable.

The base 31a of each support bracket 31
In the lower part of the frame, a frame climbing mechanism (second climbing mechanism) 36 including an electric chain block 35 provided with a hook 34 for refilling the outer periphery curing 15
Is provided.

The support bracket 3 having such a structure
1, the arms 31b and 31c are installed on the construction floor 11a,
It is fixed to the beam steel frame 13 through a bracket receiving member 37 by a fixing metal fitting (not shown) such as an anchor bolt in a state of being extended toward the base floor 11b which has already been constructed. As a result, the outer peripheral frame 22 is supported in a state of being separated from the body 11 by a certain dimension.

Next, a method of rearranging the outer cover A having the above-mentioned structure upward with the progress of the work for constructing the skeleton 11 will be described with reference to FIGS. 1 to 6. As shown in FIG. 1 and FIG. 3, in a normal state, each outer peripheral frame 22 of the outer peripheral curing 15 installed on the skeleton 11 has an inner pipe 27 inside the sheath pipe 26 of, for example, 5 m.
The length has been inserted. In this state, the roof member 20 provided on the upper surface of the frame frame 14
Then, the curing sheet 23 of the outer periphery curing 15 prevents intrusion of wind and rain into the construction site 12 and scattering of fallen objects during work.

When the construction on the construction floor 11a is completed,
When the outer cover A is to be refilled upward, it is carried out as follows. As shown in FIGS. 5 and 6, first, the climbing mechanisms 9 (see FIG. 7) of the respective masts 8 that support the frame frame 14 are simultaneously climbed to jack up the frame frame 14 for one floor. Refill upwards. At this time, each truss frame 24 of the outer peripheral frame 22 is attached to the frame 11 by the support bracket 31.
Keep it fixed to. Then each pod 2
6 rises integrally with the frame frame 14, and with this, the inner pipes 27, 27 accommodated in the sheath pipe 26 are pulled out and exposed.

After the frame frame 14 is refilled in this way, the outer periphery curing 15 is refilled. First, the hook 34 of the frame climbing mechanism 36 provided on each support bracket 31 of the outer peripheral frame 22 is attached to the hanging plate 24a formed on the lower end of the truss frame 24.
To be locked. Then, a positioning pin (not shown) is pulled out to release the fixing between each support bracket 31 and the guide rail 30. Then, each chain block 35 winds the chain at once. Then, each truss frame 24 obtains a reaction force from the support bracket 31 fixed to the skeleton 11 and ascends. Along with this, the exposed inner pipes 27, 27, ... Are stored in the sheath pipes 26, 26 ,. In this way, the outer peripheral frame 22, that is, the outer peripheral curing member 15, is guided vertically by the support brackets 31, 31 ,.

In this way, after the outer peripheral curing 15 is raised by one floor, a positioning pin (not shown) is inserted into each support bracket 31, and the support bracket 31 and the guide rail 30 are fixed again. This completes the work of refilling the outer peripheral curing 15.

Next, of the support brackets 31 provided at a plurality of locations on the outer periphery curing 15, first, one support bracket 31 is re-sorted as follows. First, one end of a wire rope (not shown) is fixed to the upper end portion of the truss frame 24, and the other end is arranged at the lower end portion of the truss frame 24 via a pulley (not shown).
5 to the hook 34. Then, the support bracket 3
Fixing metal fittings (not shown) for fixing 1 to the frame 11,
And a positioning pin (not shown) for fixing the support bracket 31 to the guide rail 30 is pulled out. After releasing the fixing of the support bracket 31 to the guide rail 30 and the skeleton body 11 in this manner, the arms 31b and 31c of the support bracket 31 are folded so as not to interfere with the skeleton body 11 when rising.

Then, the chain is wound up by the chain block 35, and the support bracket 31 is raised by one floor. Then, the arms 3 of the folded support bracket 31.
1b and 31c are extended and fixed to the skeleton 11 via the bracket receiving member 37 with a fixing metal fitting (not shown). Also,
By fixing the support bracket 31 and the guide rail 30 with a positioning pin (not shown), the work of rearranging the support bracket 31 to the upper floor is completed. In this way, while one support bracket 31 is being refilled,
The outer periphery curing 15 is supported by other support brackets 31, 31, ....

After this, the other support brackets 31, 31,
Similarly, as above, the refilling work of the outer cover A is completed at the time when all the support brackets 31 are refilled by sequentially refilling one by one.

In the above-mentioned outer cover A, the truss frame 24 of the outer peripheral frame 22 is supported by the sheath tubes 26, 26, ... Fixed to the frame frame 14 so as to be vertically slidable. As a result, the climbing mechanism 9 including the frame frame 14 on the mast 8 (see FIG.
(Refer to FIG. 4) to raise the outer peripheral curing 15 to the support bracket 31.
The frame frame 14 and the outer peripheral curing 15 can be independently climbed by elevating the frame climbing mechanism 36 provided in the above. As a result, the load of the frame frame 14 and the outer peripheral curing 15 at the time of jacking up can be divided and supported by the climbing mechanism 9 (see FIG. 7) and the frame climbing mechanism 36. Therefore, even if the floor area of the building 10 to be constructed is large and the outer covering A covering the building 10 becomes large in scale, the outer covering A can be automatically refilled, and the construction can be greatly performed. It is possible to improve efficiency. Of course, in this case, it is not necessary to increase the number of masts 8 to be installed in accordance with the scale of the outer covering A, and it is possible to suppress an increase in cost.

Further, since each truss frame 24 of the outer peripheral frame 22 has a form in which not only the support bracket 31 but also the upper end thereof is supported by the sheath tube 26, the stress distribution in the lower portion of the truss frame 24 is It is closer to the distribution of simple beams than cantilevers. Therefore, as compared with the case where the truss frame 24 is supported only by the support bracket 31, the cross-sectional dimensions of the members forming the truss frame 24 can be made smaller, and the upper portion of the truss frame 24 is also deformed. Can be made smaller.

Furthermore, when the support brackets 31 are refilled, the support brackets 31 are sequentially refilled one by one, so that even when the support brackets 31 are being refilled, the outer peripheral curing 15 is left over. It can be always supported by the support bracket 31. Thereby, it is not necessary to prepare a special support member or the like only for supporting the outer periphery curing 15 when the support bracket 31 is refilled.

In the above embodiment, the outer frame 2 is constituted by the sheath pipe 26 and the inner pipe 27 accommodated therein.
2 is supported by the frame frame 14 so as to be slidable up and down, but other than this, for example, a rail is provided on the frame frame 14 side and slidably supported on this rail on the outer peripheral frame 22 side. Other configurations such as a configuration in which a slide member is provided may be used.

Further, the outer peripheral frame 22 does not necessarily have to be integrated over the entire circumference, and may be divided into a plurality of pieces in the circumferential direction. In this case, each division may be divided and sequentially refilled. Good. Further, only a part of the outer peripheral frame 22 in the circumferential direction is climbed as in the above embodiment,
The other portions may be resized integrally with the frame frame 14. Further, although the support bracket 31 is configured to be foldable, if it is possible to prevent the support bracket 31 from interfering with the body 1 when the support bracket 31 is refilled, the support brackets shown in FIG. Other structures such as 31 'may be folded in two steps in a horizontal plane. In addition, the frame climbing mechanism 36 is configured to use the chain block 35, but the structure is not limited,
As long as the outer periphery curing 15 can be refilled, another structure may be used, such as a configuration including a hydraulic cylinder that expands and contracts in the vertical direction, similar to the climbing mechanism 9 of the mast 8.

Of course, it goes without saying that the outer coating A may be refilled for every two floors or at a pitch higher than that.

Further, in the above-mentioned embodiment, the curing sheet 23 is stretched on the outer peripheral surface of the outer peripheral frame 22 for the purpose of preventing wind and rain. In addition to this, a scaffolding plate is attached to the outer peripheral frame 22. May be used as a temporary scaffold, or other things such as the frame 11 and the formwork for forming the wall surface may be installed and refilled. Even in such a case, the same effect can be obtained by applying the same configuration as described above.
Further, the frame frame 14 may be a temporary structure, or may be configured by a main body structure on the uppermost floor of the building 10 that is preassembled. In addition, the outer coating A is
It is needless to say that the present invention is not limited to being applied only to the outer peripheral portion of the skeleton 1, and can also be applied to the inner peripheral portion such as the shaft portion or blow-through portion of a building.

[0035]

As described above, according to the outer cover of the present invention, the outer cover is hung on the frame portion of the frame installed above the skeleton via the supporting column and the peripheral edge portion thereof. The outer peripheral frame part is installed and is removably fixed to the body by a supporting member, and the outer peripheral frame part is supported by a guide member fixed to the frame part so as to be slidable in the vertical direction. Accordingly, if the frame frame portion is raised by the first climbing mechanism and the outer peripheral frame portion is raised by the second climbing mechanism, the frame frame portion and the outer peripheral frame portion can be independently climbed, and the jack The load of the frame frame part and the outer peripheral frame part at the time of up can be divided and supported by the first climbing mechanism and the second climbing mechanism. Therefore, even if the floor area of the building to be constructed is large and the outer covering that covers it is large, it is possible to automatically refill this outer covering, which greatly improves the construction efficiency. Can be achieved. Of course, at this time, it is not necessary to increase the number of support columns that support the frame member in accordance with the scale of the outer cover, and it is possible to suppress an increase in cost. Further, since the outer peripheral frame portion is supported by the guide member and the supporting member, the stress distribution in the lower portion of the frame body is closer to the stress distribution of the simple beam than the cantilever beam. Therefore, it is possible to reduce the cross-sectional size of the member that constitutes the frame body and to reduce the deformation thereof.
