Description

[Detailed description of the invention] [Industrial application field] The invention relates to a simple building such as a warehouse, a garage, and a temporary accommodation in an emergency.

[Prior Art] Conventionally, as a simple building that can be constructed in a warehouse or an emergency temporary accommodation room and can be constructed in a short time, a frame is formed with a metal pipe or the like, and a waterproof fabric is formed thereon. An extended, so-called tent-type simple structure can be mentioned.

[Problem to be Solved by the Invention] However, when trying to make a large-scale structure using a conventional tent-type simple building, a large amount of aggregate is required for building the frame. The major reason is that the waterproof fabric spread thereon does not always have sufficient strength, and a large amount of aggregate must support the waterproof fabric. It is possible to increase the strength of the waterproof cloth by increasing the basis weight of the waterproof cloth, but if the basis weight is high enough to obtain sufficient strength, the weight of the waterproof cloth becomes extremely high, and the work at the time of spreading on the skeleton. Therefore, it is required to use a thick aggregate capable of withstanding a high weight as a framework for supporting the prevention cloth.

Further, the conventional tent structure has a drawback that the waterproof fabric flaps due to the wind, and the fluttering sound at that time is loud.

An object of the present invention is to provide a tent-type building that does not impair the workability of spreading the waterproof fabric even when the building is made large, does not require the use of a large number of frames, and further produces a rattling sound. It is an object of the present invention to provide a sheet which can be spread under the prevention cloth, which can reduce the amount of the sheet.

[Means for Solving the Problems] That is, in the present invention, in a simple building composed of a skeleton and a waterproof cloth spread thereon, a fiber cord is formed under the waterproof cloth and is covered with a resin. This is a simple building characterized by extending net-like objects.

The present invention uses rods or panels made of metal or wood such as iron or aluminum as a framework, and forms a basic framework such as columns and beams, and furthermore, constructs by stretching metal wires or wire ropes as necessary. In the skeleton, a spun yarn or a filament yarn is twisted, a strand obtained by twisting, and the like, and a fiber cord formed as a twisted or knitted yarn obtained by twisting a plurality of strands, if necessary, for example, with a warp and a weft, or The net is formed into a net-like material, and the net-like material is processed with a resin. When covered with a resin, a sound-absorbing effect against sound caused by "fluttering" due to wind or the like is further obtained.

The coating according to the present invention may include a part that is not partially coated.

The nets obtained are spread on the roof of the structure or on the basic framework of the perimeter and the roof. Then, a cloth such as a plain woven cloth or a canvas, or a waterproof cloth coated with a waterproofing agent or a resin is stretched on the net-like material to obtain a simple structure such as a warehouse.

The fibers constituting the net-like material of the present invention include natural fibers such as cotton and hemp, regenerated cellulose fibers, nylon fibers, polyester fibers, polyvinyl alcohol fibers, vinyl chloride polymer fibers, vinylidene chloride polymer fibers, and aromatic fibers. It is at least one kind of fiber selected from the group of fibers such as group-based polyamide fibers, polyethylene fibers, polypropylene fibers, and acrylic polymer fibers.

The thickness of the fiber cord, the structure of the net-like material and the size of the eyes of the net, and the like differ depending on the size of the desired structure, the site to be used, and the like.
000 denier, and the size of the net eyes (inter-gap) is in the range of 0.5-50 cm. The net weight of the net is preferably 50 to 500 g / m ^{2 on} average.

The resin used when the net-like material is resin-processed to cover the fiber cord with the resin and fix the knot is, for example, a vinyl chloride resin, polyurethane, butadiene / acrylonitrile copolymer, styrene / butadiene. It is a resin selected from the group of a copolymer, a synthetic rubber such as an acrylic resin, or a natural rubber, and is preferably an elastic resin. Preferably, it is a flame retardant-containing resin composition or a flame-retardant resin. The resin is used as a resin solution dissolved in a solvent, a resin dispersion liquid dispersed in a dispersant, or an emulsion liquid. Further, the resin liquid is used as a resin composition liquid to which additives selected from a foaming agent, a flame retardant, a coloring agent, a filler, a plasticizer, a stabilizer and the like are added as required. The resin processing of the net-like material is performed by immersing the net-like material in a resin liquid or a resin composition liquid and removing excess resin liquid,
By drying or immersing the resin in a coagulating liquid to solidify the resin, a net-like material composed of resin-coated fibers is obtained. The feature of resin processing of the fiber cord of the net-like material is that the net-like material stretched on the skeleton greatly reduces or eliminates the friction noise and flapping sound generated between the waterproof fabric stretched on the skeleton and the skeleton, Further, the wear resistance can be improved.

FIG. 1 shows an example of a framework for extending a net-like object, in which 1 is a basic framework. FIG. 3 is a schematic view of a net-like object, and (1) is a net-like object made of a fiber cord;
(2) is a schematic view of a net-like object made of a resin-processed fiber cord, 3 is a fiber cord, and 4 is a resin coating film.

By spreading the net-like object of the present invention on a frame and spreading a waterproof cloth on it, a small amount of aggregate for the frame of the structure can be used, and a large facility that does not require complicated and exaggerated construction is constructed. Construction or dismantling work time is short, and waterproof fabric and net-like material are
Lightweight and foldable or wrappable for easy storage. Further, since it is not necessary to particularly increase the basis weight of the waterproof cloth in order to increase the strength of the waterproof cloth, workability is also excellent from this point. Further, since the net-like object can be cut freely, the design and design are free, and a unique structure can be easily obtained.

Next, the embodiments of the present invention will be described with specific examples.

Comparative Example 1 Two twisted yarns obtained by twisting two polyethylene terephthalate filament yarns having a yarn fineness of 1500 dr.-100 fil. Were further twisted into three strands, and three more strands were twisted into a fiber cord. Using this fiber cord, a net I having a width of 3 m and an average distance between joints of 5 cm (average basis weight 125
g / m ² ), and the mesh was spread on the roof of a simple warehouse having a width of 4 m, a depth of 10 m, and a height of 3 m as shown in the schematic diagram of FIG. In other words, on top of a concrete block laid as a base, steel square pipes are erected at 2 m intervals, outer wall panels are assembled and covered, and 25 mm iron panels are arcuately mounted on the roof beams at 1 m intervals. Then, the top portion was fixed with an iron pipe extending sideways to form a skeleton, and then the net I was placed thereon and partially fixed to the pipe. Next, a waterproof fabric made of polyvinyl alcohol fiber is stretched,
A simple warehouse was completed with the surrounding edges fixed. The 3% elongation stress of the mesh I was higher than that of the waterproof fabric on average.

The construction of this warehouse was easy to fix the foundation, and it took less than a day for two people to complete the foundation. Although the waterproof fabric and the net were not broken by long-term use, a rattling sound was generated by the wind.

On the other hand, when the waterproof fabric was stretched directly on the skeleton without using the mesh, the rattling sound was large and tearing occurred due to long-term use.

Example 1 The reticulated material I obtained in Comparative Example 1 was treated with a vinyl chloride resin emulsion composition containing a phosphate ester plasticizer, a colorant, a stabilizer, a surfactant and a foaming agent, and then heated to 125 ° C. Then, drying and heat treatment were performed in a heating furnace while increasing the temperature to 150 ° C. to obtain a net II made of a vinyl chloride resin-coated fiber cord (average basis weight 250 g / m ² ). This net I
I was used for the roof of temporary housing. In other words, a roof frame is formed by installing a frame with a piano wire stretched over a wooden frame on the roof,
After placing the net II thereon, it was partially fixed, and then covered with a cloth having a silver paint film on one side of a nylon fiber canvas, and the periphery was partially fixed to complete a temporary house. Also in this case, the relationship between the mesh II and the waterproof fabric was the same as in Comparative Example 1.

For comparison, a temporary housing was similarly made using the mesh material I.

I lived in this temporary housing and compared the noise caused by the weather. As a result, the house of this example had a particularly great sound-deadening effect even when it was blown by the wind.
