Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a method for temporarily setting up a tent for rainy weather at a construction site where a building is constructed using construction scaffolding.

[Prior Art] (Background) If it rains during the construction of a building, the construction must be stopped unless the roofing work has been completed. The completion date will be delayed. This is especially true for types of work that cannot be restarted until areas that have been wet by rainwater have completely dried out, such as plastering.
In cases where rain occurs while painting or waterproofing work is being carried out, the rain can cause a significant delay in construction work, which not only increases the construction cost due to the extension of the construction period.
In some cases, this may result in undesirable consequences such as delays in the delivery date and payment of severe penalties.

(Latest prior art) Therefore, in conventional construction work, for areas that are unavoidable to get wet during rainy weather, those areas are covered with construction sheets, or disposable vinyl is hung over them and adhesive tape is used to cover them. They had done some fixing and other things.

[Problem to be solved by the invention] However, when covering with a construction sheet, conventionally the lobes are passed through a ring-shaped metal fitting called an eyelet (end stop) provided along the edge of the sheet side. The construction sheet was fixed by lashing it to a suitable fixed object, so in the event of strong winds, the sheet would catch the wind and the strong wind force would concentrate directly on the eyelet area, causing the sheet to be damaged along with the eyelet. This can cause accidents such as tearing the side edges. The occurrence of this accident makes it impossible to reuse relatively expensive construction sheets, so the method of covering with construction sheets has the drawback of increasing the burden on the construction company.

On the other hand, with the method of fixing disposable vinyl with adhesive tape, the price of the vinyl itself becomes cheaper, but it is undeniable that it is uneconomical because it is disposable, and there are also problems with durability compared to covering it with construction sheets. Therefore, the degree of damage caused by strong winds is likely to be greater than the damage caused by the case covered with the construction sheet described above, and the waterproofing effect will be worried accordingly.

Another method is to enclose the top of the steel frame with a tent to make it waterproof, but this method is not only extremely disadvantageous in terms of cost, but also due to the site conditions of the construction site. Its use is extremely rare due to its limitations.

The present invention was made in view of this situation, and has excellent waterproof effect, strength, and durability as a roof substitute, and can withstand reuse until the strength and function of construction sheets are lost.
A further object of the present invention is to provide a method for temporarily setting up a tent for rainy weather that is advantageous in terms of cost.

[Means for Solving the Problems] The configuration of the present invention for achieving this object is a method for temporarily erecting a tent for rainy weather at a construction site where a building is constructed using construction scaffolding. ) Metal three-dimensional truss structures with polygonal end faces of triangular or larger end shapes are installed facing each other on the top of the construction scaffolding located on both sides, and the two three-dimensional truss structures are installed almost parallel to each other between the two three-dimensional truss structures. At the same time, a plurality of rib lobes are stretched in a direction intersecting the stretching direction of the girder direction ropes, and a plurality of rib lobes are stretched almost parallel to each other in a direction intersecting the stretching direction of the girder direction ropes. The purpose is to hold the construction sheet in a planar manner by a mesh rope formed by two types of rope groups, and to temporarily fix each side edge of the construction sheet to at least the construction scaffolding. In this case, the scaffolding for construction needs to be strong and solid as a whole, so it is preferable that it is made of metal pipes that surround the building. This is because the side located in the longitudinal direction of the structure (
For example, it is effective to select the gable side of the building.

In addition, it is desirable that the three-dimensional truss structure be as light as possible while maintaining the necessary strength, and have a structure that allows for rotational disassembly and assembly on a scaffold. Assemble the aggregate.

It is preferable to have a structure that can be completed together. Furthermore, it is preferable that the end face shape is such that the girder direction rope extending at the top becomes a watershed line, particularly triangular.

The girder direction rope is preferably a metal stranded wire rope with excellent strength, and the rib lobes are preferably non-metallic lobes that can be folded and used together with construction sheets.

Further, it is preferable that the mesh lobes are formed in a mesh shape such that the girder direction ropes and the rib lobes are orthogonal to each other.

Therefore, the construction sheet is preferably made of canvas, which has excellent strength, but it may also be made of synthetic resin with reinforcing material, and has eyelets on each side edge and has predetermined intervals on the entire surface. It is preferable to have a plurality of lobe passage pieces through which rib lobes aligned with each other can be passed.

[Function] Based on this configuration, the action of the present invention is based on the girder direction rope group stretched between the three-dimensional truss structures provided oppositely, and the rib ropes stretched so as to cross these. A mesh rope is formed and the work 4V sheet is held by the mesh rope.

In this case, the method of combining the girder direction rope group and the rib rope group with the construction sheet is as follows: ■ Each of the rib rope groups is individually stretched across the girder direction rope group, and both of the ropes stretched in a mesh are stretched. The top of the rope group is covered with a construction sheet, and then the sheet is secured to both or one of the rope groups using a thin lashing rope or the like.

■ After extending the girder direction rope group, cover with a construction sheet, extend the rib rope group from above the sheet, and secure the sheet to both or one rope group using thin lashing lobes, etc. .

■ A large number of rope loop pieces are installed in advance on the side of the construction sheet, and before the sheet is covered, the rib lobes are passed through the rope loop pieces and assembled integrally with the construction sheet. Both ropes are covered over the expanded girder direction rope group so as to form a mesh, and then the construction sheet is secured to the girder direction rope group.

In addition, the fixing of the girder direction rope group to the three-dimensional truss structure and the fixing of the rib lobe group to the construction scaffolding shall be done by any appropriate method. It is preferable to fix each side edge of the structure not only to the construction scaffolding but also to the three-dimensional truss structure.
As for the method of fixing them, for example, it is desirable to provide eyelets on each side edge of the sheet, and to tie a thin cod rope or the like through the eyelets to a scaffold or the like.

[Example] Hereinafter, the present invention will be described in detail based on illustrated embodiments.

FIG. 1 is an overall perspective configuration diagram showing the overall schematic configuration when a rain tent is temporarily installed on top of a construction scaffold by the temporary construction method of the present invention. The building itself is omitted.

In the figure, the rainy weather tent temporarily constructed by the method of the present invention is
A construction scaffold 10 constructed to surround a building (not shown), and a construction scaffold 10 that is attached to the top of a scaffolding portion located opposite in the longitudinal direction (for example, on the gable side) of the construction scaffold IO. Three-dimensional truss structures 20 and 20 degrees whose end faces are triangular in shape, and a girder direction rope group 30 consisting of, for example, five wooden ropes stretched almost in parallel and under tension between the three-dimensional truss structures 20 and 20 degrees. , a rib rope group 40 consisting of, for example, five ropes stretched substantially parallel to each other in a direction intersecting (preferably perpendicular to) the stretching direction of the girder direction rope 30, and these two groups of ropes 30.・
It is composed of five basic members: a construction sheet 50 that is placed over a mesh rope N formed by 40 intersections.

Among them, the construction scaffold 10 is constructed as an assembled scaffold of a known steel pipe structure with a predetermined scaffold width, and is constructed to surround a building (not shown).

The three-dimensional truss structures 20 and 20'' are made of, for example, light alloy square pipe aggregate with 60 layers on each side, 60 m layers, and 2.4 layers in thickness, and when completed, they will have the same shape as shown in Figure 2 (A). (B)
It is constructed as a structure that can be disassembled and reassembled on the scaffold IO so that it has the shape shown in FIG. This configuration allows the construction sheet 50 to be used during strong winds.
A large wind pressure is applied to the structures 20 and 20, resulting in a total wind force.
This is to ensure that the aggregates 21 and connecting members 22 to 2 constituting the three-dimensional truss structure 20 (only one is shown) have the strength to withstand even if the
For the method and structure of disassembly and combination with 6, etc., an appropriate method and structure known per se shall be used.

The girder direction rope group 30 is made of metal stranded wire rope with excellent strength, and the girder direction rope 31 located at the center is connected to the three-dimensional truss structure 20, 20° so as to serve as a watershed line. The other girder-direction lobes are stretched substantially parallel to and at approximately the same intervals as the girder-direction ropes 31 of this watershed line. In this case, the space truss structure 20
The attachment and tensioning method of each opening 30 to each of
The structure shall be used.

The rib rope group 40 is a construction sheet 50 which will be described later.
It is made as a foldable non-metallic rope, for example, a hemp fiber rope, and its length is set so that it protrudes a predetermined amount from the side edge 51 of the construction sheet 50.

The construction sheet 50, as shown in FIG. 3(A),
In the free state, it is configured as a rectangular (planar) sheet made of canvas, for example, and on the entire side edge thereof, as shown in FIG. be arranged in a row. The entire surface of the sheet 50 is provided with a plurality of rows of rope passing pieces 52 in the longitudinal and lateral directions, respectively.

This group of rope passing pieces 52 is made to have a shape (60 mm x 20 mm) and structure as shown in FIG. Each rope 40 and the construction sheet 50 are integrated by passing it through the semicircular bulge 52a of the rope 52.

Therefore, the hem portions 52b on both sides are firmly perforated to the seat portion so as to be able to sufficiently withstand strong wind pressure. Note that, as the construction sheet 50, a synthetic resin sheet containing reinforcing material may be used instead of the canvas sheet.

Next, each of the basic members IO to 50 configured in this way
Explain how to temporarily set up a tent for rainy weather using.

[Construction of scaffolding for construction work 1 Steel pipe structure is assembled using scaffolding materials to surround the building under construction, but as the scaffolding materials and construction methods are publicly known, explanations will be omitted. .

[Assembling the three-dimensional truss structure J: Each component member 21 to 26 in a disassembled state is mounted on the upper part of the scaffold part located opposite in the longitudinal direction of the construction scaffold 10 as shown in Figs. 2(A) and (B). Assemble the triangular space truss structures 20 and 20' shown in FIG.

[Stretching of girder direction rope group 1 As a typical stretching method, the central girder direction rope 31 is stretched on the tops of the opposing three-dimensional truss structures 20 and 20', and with this as a reference, other girder direction ropes are stretched on both sides. rope group 30
are extended almost in parallel. Then, apply tension using an appropriate method. At this time, in order to prevent the three-dimensional truss structures 20, 20' from tilting inward due to this tension, the three-dimensional truss structures 20, 20' must be firmly fixed to the construction scaffolding 1O, and the necessary In some cases, reinforcing column members (
(not shown) shall be attached.

[Formation of mesh lobes] When the connection relationship with the construction sheet 50 is considered, there are three methods for forming the mesh lobes N as follows. That is, (1) The rib rope groups 40 are individually stretched across the girder direction rope groups 30, and the construction sheet 50 is placed over both rope groups stretched in a mesh pattern, and then the lashing ropes are Secure the sheet to both or one group of ropes using thin ropes.

■ After expanding the girder direction lobe group 30, the construction sheet 5
0, extend the rib group 40 from above the sheet, and secure the sheet to both or one of the rope groups using a thin lashing rope or the like.

■ A large number of rope loop pieces 5 are placed in advance on the side of the construction sheet 50.
2, and before covering with the sheet, pass the rib rope group 40 through the rope passing piece 52 and combine it integrally with the construction sheet. Cover both ropes so that they form a mesh pattern.
Thereafter, the construction sheet 50 is secured to the girder direction rope group 30.

This is the method.

[Stretching of the construction sheet] In the case of the illustrated embodiment, the mesh rope N is formed by the method in item 0 above, so the work of forming the mesh rope N and the stretching of the construction sheet 50 are performed at the same time. It will proceed.

One typical method will be explained below. First, the construction sheet 50 is folded in half, and the folded part is carried by a manual winch 60 attached to the construction scaffold 10, for example.
Lift onto the aforementioned reticulated lobe N. Then, the folded portion is placed on the center girder direction lobe 31, and then the sheet 50 is spread out to the left and right, and the entire sheet surface is spread out on the mesh rope N. When the deployment is completed, a thin rope for lashing (not shown) or the like is passed through the eyelet fitting 51 of the sheet 50 and lashed to appropriate locations on the scaffold 10 and the three-dimensional truss structure 20 and 20°.

As explained above, in the method for temporarily erecting a tent for rainy weather according to the present invention, the three-dimensional truss structure images 20.・Make a substitute roof skeleton (mesh rope N) with the girder direction rope group 30 stretched between 20 degrees and the rib rope 40 stretched across it, and cover it with the construction sheet 50. Since it was used as a substitute roof, it became impossible to temporarily erect a lightweight and strong tent for rainy weather with relatively simple work.

Although one embodiment has been described above, the present invention is not limited thereto, and it should be noted that various modifications can be made without changing the gist of the invention.

[Effects of the invention] As stated above, when A-Ming is used, it has excellent waterproof effects, strength, and durability as a substitute for B binding, and can withstand reuse until the strength and function of construction sheets are lost. Furthermore, it is possible to realize a method for temporarily setting up a tent for rainy weather that is advantageous in terms of cost.
