Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a Nanban plaster package used for roofing of buildings, particularly for roofing.

(Prior Art) Conventionally, in roofing construction, as shown in FIG. 3, a field board 12 is stretched on a rafter 11, and a waterproof paper 13 is laid directly or on the field board 12. Nanban stucco, which is the earthen roof
14 is placed and a roof tile 15 is laid on the plaster 14, and the Nanban plaster 14 serves as an adhesive for the roof tile 15.

This Nanban plaster 14 is used by being mixed and kneaded in proper amounts of lime, river sand, bamboo grass, paste (for example, ginnan paste) and water at the work site.

(Problems to be solved by the invention) By the way, the above-mentioned Nanban plaster is mixed and kneaded at the roofing construction site, so lime is scattered and forms a fumes, causing workers to have difficulty breathing and scattering to nearby areas. In addition to deteriorating environmental hygiene and annoying neighbors, there is a problem that the above-mentioned mixing and kneading work requires considerable skill and labor and is extremely inefficient.

In addition, Nanban plaster has air-hardness, and therefore it cannot be kneaded and held in a large amount at a time. Was needed. Further, the kneaded Nanban plaster had to be carried to the roof, and the work of carrying it up was difficult.

The present invention has been made in view of the above-mentioned circumstances,
The purpose is to eliminate the need for compounding and kneading work and skill at the tile construction site, prevent deterioration of environmental hygiene due to lime scattering at the site, and long-term storage is possible.
It is to provide a Nanban plaster package that can simplify the tile construction and reduce the number of workers.

(Means for Solving the Problems) In order to achieve the above object, the present invention takes the following means.

That is, according to the present invention, at least an airtight and strong bag body 2 is filled with at least nanban stucco 3 which is made into a substantially paste by mixing lime, river sand, grass, paste, and water in a predetermined ratio and kneading the mixture. A sealed Nanban plaster package, the bag body 2
A polymer absorber that absorbs moisture is additionally provided on the inner surface of the.

(Operation) According to the present invention, a certain amount of homogeneous and identical Nanban stucco, which is metered and mixed in a certain ratio in a factory, is filled and sealed in a predetermined amount in an airtight bag, so that the air is completely removed. It can be stored for a long time because it is blocked by carbon dioxide and hardened by carbon dioxide. On the other hand, the Nanban stucco in the airtight bag is kneaded and compounded with a water-insoluble substance such as ease of river sand, so when it is stored for a long period of time, moisture can be gradually separated, but on the inner surface of the bag used in the present invention. Since a polymer absorber that absorbs moisture is installed, this polymer absorber absorbs separated moisture, so a moisture layer is not formed even after long-term storage, and it is a paste of Nanban plaster. Can hold.

Therefore, if the Nanban plaster package is carried on the roof substrate and then opened, the paste-like Nanban plaster can be taken out regardless of the number of days of storage. After the paste-like Nanban plaster taken out is flattened on the roof substrate and tiles are arranged on it, Nanban plaster cures due to its air-hardness and the tiles can be fixed by adhesion. Therefore, if the Nanban plaster of the present invention is used,
The adhesive strength of Nanban stucco can be effectively used for strong adhesive fixing.

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

In FIGS. 1 and 2, reference numeral 1 denotes a Nanban plaster package, in which a raw material is metered and blended in a predetermined ratio in a transparent or translucent, airtight, tough, flat tubular bag 2 made of synthetic resin. It is filled with the kneaded, substantially paste-shaped Nanban plaster 3, and the opening 4 is hermetically sealed 5 by a heating and pressure bonding means.

The bag body 2 is formed by printing on a continuous cylinder formed by an inflation method or the like, forming a bottom portion 6 by heating and pressurizing means, and then cutting it to form an opening portion 4. Material and strength (allowable compressive stress,
Adhesive strength etc.), weight (eg 25 kg), capacity etc. are printed.

An appropriate amount of a polymer absorber (not shown) that absorbs moisture is attached to the inner surface of the bag body 2. This polymer absorber appropriately absorbs water that may be separated from the Nanban stucco 3 in the bag body 2 and prevents the Nanban stucco 3 kneaded and mixed in a paste form from separating into a liquid layer and a solid layer. .

The Nanban plaster 3 is made by kneading lime, river sand, grass, paste (Ginnan Nori), and water at a predetermined mixing ratio for a certain period of time to form a paste, and these raw materials are weighed by a weighing machine, After being put into a mixer and kneading for a certain period of time, the bag body 2 is packed. Weighing these ingredients,
Kneading, etc. are carried out in the factory, especially for lime, after opening it, put it in a mixer so that dust will not scatter,
Mechanically and automatically in the hood.

The strength of Nanban plaster 3 can be changed by arbitrarily changing the mixing ratio of the raw materials.

Then, after the kneading by the mixer is completed, the bag 2 is sequentially filled, and air is discharged from the opening 4 to prevent air from remaining inside the reservoir, and then the opening 4 is sealed by the heating and pressing means. It These operations can also be performed mechanically and automatically.

When the Nanban plaster 3 is filled in the bag body 2, it is desirable to print the manufacturing date and / or the warranty expiration date.

As described above, the Nanban plaster 3 that is filled and sealed in the bag body 2 is air-hardening, but since contact with air is completely blocked, curing by carbon dioxide does not proceed, It can be stored for a long period of time as long as the bag 2 is not broken or the hole is not formed.

The filling amount, that is, the weight of the Nanban plaster 3 is preferably less than the weight that can be carried by a person, such as 25 kg, 20 kg, 15 kg, 10 kg.

The nanban stucco 3 packaged as described above is purchased in a necessary amount at the time of use, carried on a roof substrate, the bag body 2 of the nanban stucco package 1 is opened at the time of laying, and the banban stucco 3 is taken out, After placing this on the roof substrate and flattening it flat, the roof tiles may be arranged on the Nanban plaster 3 and adhesively fixed. The time from opening the bag body 2 to arranging the tiles and adhering them is extremely short, and therefore the adhesive force of the Nanban plaster 3 is not reduced.

(Effect of the Invention) In the nanban stucco package according to the present invention, since the air-hardened nanban stucco is sealed in the airtight bag body as described above, the hardening of the nanban stucco can be prevented. Furthermore, since the water that can be generated due to the separation is absorbed by the polymer absorber attached to the inner surface of the bag, the Nanban plaster package of the present invention allows the Nanban plaster to be held in a substantially paste form for a long period of time. Can be saved.
In addition, when using it, since it can be opened and immediately laid on the roof substrate, there is no need for a raw material mixing and kneading work at the roofing construction site, and no worker is needed for that, so there is no kneading worker. Can use Nanban stucco as thatch and reduce the number of workers, and since there is no kneading work on site, there is no risk of lime being scattered in the neighborhood and harming environmental hygiene, so it is possible to work with peace of mind. In addition, it is easy to transport to the roof substrate and extremely easy to handle, and it is possible to simplify the roofing work and improve work efficiency.
