Description

[Detailed description of the invention] The present invention can be applied, for example, to school classrooms, hallways, and gymnasiums.

Alternatively, the floors of various playgrounds, assembly halls, and even reception rooms require high levels of strength, elasticity, smoothness, durability, etc. due to the relatively intense physical activity. This is a construction method that is often applied, and specifically relates to a flooring block tensioning method in which flooring blocks are laid and fixed on a mortar base formed to an appropriate thickness on a concrete slab.

In this type of conventional flooring block installation method, angle-shaped foot fittings are protruded and fixed to the underside of wooden flooring blocks made of beech, nara, itaya maple, morning sunflower, and other hardwood species designated as broad-leaved trees (Japanese Agricultural Standards). Then, place this foot fitting on the raw mortar base, that is,
Previously, the block was installed using the so-called wet method, in which the block was mixed and kneaded by the technician himself on site, and then embedded directly into the uncured mortar base. In this case, not only does it require a lot of time and hard labor for the block-laying technician, but it also requires the technician to have advanced construction techniques.
Due to the shortage of highly skilled technicians, construction ability and
There is naturally a limit to the construction speed, and as a result, this has had a considerable negative impact on the construction of not only the floor structure but also the building as a whole.

Especially when carried out in public buildings such as schools,
Because the construction periods are concentrated, the aforementioned shortage of skilled workers will lead to various problems, which is a cause for concern for this type of construction method, which has seen an increasing demand in recent years.

In view of the current situation, the present invention has been developed through intensive research into the development of an innovative construction method that departs from conventional construction methods in order to meet the increasing demand. The purpose of this invention is to provide a flooring block installation method that can fix flooring blocks to a mortar base.

In the flooring block installation method according to the present invention, after a mortar base layer formed on a concrete slab has hardened or almost hardened, an adhesive is applied to the surface of the mortar base and flooring blocks are laid in order. The method is characterized in that the flooring block is adhesively fixed, a nail is driven into the mortar base through the flooring block and its adhesive, and the flooring block is crimped and fixed to the mortar base.

In other words, the construction method of the present invention entrusts the construction work of the mortar base to the concrete slab construction contractor, thereby saving the labor and skills required for block-laying technicians.In other words, during block-laying construction, The work that depends on the skilled worker can be reduced to only the original work of applying the adhesive, laying the flooring blocks, and nailing the blocks, and such work can be done using the dry method. By doing this, we can not only increase the construction capacity and significantly shorten the construction period for the entire building compared to conventional construction methods, but also lower the level of construction technology, which eliminates many problems that arise with conventional construction methods. The shortage of skilled workers, which was a contributing factor, can be resolved, and the tendency for construction periods to be concentrated can be adequately addressed.

Furthermore, by using adhesive and nails in combination, the blocks can be firmly crimped and fixed to prevent looseness, and there is less influence from moisture from the mortar base, so there is less chance of blistering, warping, or other irregularities in the floor. As a result, we can now expect a highly accurate finish.

Examples of the construction method of the present invention will be described in detail below based on the drawings.
First, a mortar base 2 with a thickness of about 30% is formed on a concrete slab 1 with a horizontal accuracy such that the absolute value of the difference in surface height is within 2% within 2 m in length. , the laitance of the underlying surface is electric polyurethane.
or a grinder, etc., and wipe off oil stains with a solvent, and then thoroughly clean the surface.

When the mortar base 2 is dried to a water content of 15% or less and hardened, it has a high adhesive strength like an epoxy solvent-based adhesive, and is water resistant, oil resistant, heat resistant, and aging resistant.・Excellent chemical resistance.

Apply water-resistant adhesive 3 for wood/cement mortar to the surface of the mortar base 2 at a rate of approximately 0.7 kg/m3, and spread it evenly on the surface of the mortar base 2. % thickness and two deep grooves 6 with a width of 5% on the lower surface are joined together with corrugated nails and shaped into one side or square, and the center Float 4 with nail holes 7 formed at five locations is inserted in a checkered pattern as shown in Fig. 2, and a pneumatic mortar nail is driven through the nail hole 7 to the length of hardened zinc. A special steel needle 5 having a hardness of about 29% is driven in to press and fix the flooring block 4 made of the adhesive 3 and the top nail to the mortar.

Then, the surface side of the pressure nail hole 7 is as shown in FIG. Drive in and embed, after construction, approximately 24:1 The construction work will be completed after some time. In addition, as mentioned above, Florin Dub By forming a groove 6 on the bottom surface.

It has the advantage that the deformation due to warping of the nail 4 itself can be sufficiently reduced by 1, and the bonding area can be expected to be even more secure.
