Abstract

PURPOSE:To improve work efficiency, by joining a plaster board to an aerated concrete ground through an elastic sheet, and by fixing the plaster board to the concrete ground with a set-nail. CONSTITUTION:Over the surface of a ground 1 made of ALC (aerated lightweight concrete), a spongy elastic sheet 2 and a plaster board 3 are joined and the plaster board 3 is driven and fixed to the ground 1 with a set-nail 4. The set-nail 4 is made in a way that a threaded part 43 of a flat countersunk head screw 42 is inserted through the upper end of a pipe 41, made of stainless steel or the like, and integrally connected to the pipe 41 with press working. Then, the sheet 2 is elastically pressed by the nail 4, allowing the tapered plane 45 of the screw head to thrust into the board 3 and making the screw head face flush with the board surface. With the above-mentioned processes, work efficiency can be improved and dew condensation and water infiltration can be prevented tool.

Description

[Detailed description of the invention] <Industrial application field> This invention relates to a gypsum boarding method.

<Conventional Technology> A conventional gypsum boarding method includes the GL method. In this construction method, as shown in FIG. 3, a gypsum board 7 is attached to a foamed concrete base 5 using an adhesive 6 containing resin and mortar called Dango paste.

<Problems to be Solved by the Invention> However, the above-mentioned adhesive 6 is literally a lump of linear material of a certain size, and is arranged at appropriate intervals between the base 5 and the gypsum board. By drying, the base and the boards are bonded together.

This construction method has the problem that it takes a long time to deform each adhesive 6 to have a uniform thickness, to align the surfaces of adjacent gypsum boards 7, and to align the joints. Moreover, in this construction method, a cavity 8 is created between the base 5 and the gypsum board 7 due to the adhesive 6.

This cavity 8 is not a fraud that makes it difficult for the adhesive 6 to dry;
When an external force is applied to the corresponding plasterboard 7, the board 7
It has the disadvantage of causing tears.

Furthermore, the gypsum board 7 has a number of problems, such as condensation due to internal and external temperatures, or water droplets that have entered from joints in the outer wall.

Therefore, this invention is a new gypsum board covering that solves the above problems at once by joining gypsum board to a foam concrete base via an elastic sheet and fixing this gypsum board to the base with pegs. The purpose is to provide construction methods.

Means for Solving the Problems〉 ′ To explain in detail the present invention to achieve the above object, the construction method of the present invention includes applying an elastic sheet to the surface of the foamed concrete base and plasterboard to the surface of the elastic sheet. The gypsum board is then fixed to the foamed concrete base using nails.

According to the construction method of this invention, the gypsum board is bonded to the foam concrete base via an elastic sheet, and the gypsum board is fixed to the foam concrete base using pegs. It has better workability than the conventional construction method using a mixed adhesive, and by utilizing the elasticity of the elastic sheet, the joints of adjacent gypsum boards can be aligned easily and with high precision.

In addition, with this construction method, the space between the base and the board is sealed with an elastic sheet, which improves the sound insulation effect and
It has the effect of achieving the purpose of the invention, such as preventing the gypsum board from tearing due to cavities, preventing dew condensation, and preventing water from entering through the joints of the exterior wall.

<Example> The drawing shows a cross-sectional view of gypsum boarding to which the construction method according to the present invention is applied.
A foamed concrete called L・C is used as a base, a sponge-like elastic sheet 2 is bonded to the surface of the base 1, a gypsum board 3 is bonded to the surface of the elastic sheet, and this gypsum board 3 is lowered using pegs 4. 11! ! 1 and fixed.

As the peg 4, any type of nail can be used as long as it can be driven into foamed concrete.

The peg 4 of the embodiment is assembled by inserting the bushing shaft part 43 of a countersunk screw 42 into the upper end of a stainless steel vibrator 41, applying press work to the vibrator 41, biting the inner surface into the thread groove, and integrally joining the vibrator 41. There is ζ.

At the tip of the vibrator 41, a groove 44 having a deep tip and shallow in the direction of the shaft body is formed by press working to strengthen the nail shaft vibrator.

However, in the construction of this invention, the elastic sheet 2 is directly joined to the foam concrete base 1, and after the gypsum board 3 is joined to the elastic sheet 2, this gypsum board 3 is fastened with pegs 4. Drive it into the base 1 and fix it.

At this time, the gypsum board 3 is pressing against the elastic sheet 2, and the tapered surface 45 of the screw head of the peg 4 bites into the gypsum board 3, so that the screw surface is aligned with the board surface.

After fixing the gypsum board 3 to the entire surface of the foamed concrete base l via the elastic sheet 2 as described above, the adjacent board 3
Perform joint alignment.

During joint alignment, the protruding board 3 is corrected by further driving the pin 4 to compress the sheet 2, and the over-driven part is corrected by flattening the countersunk screw 4 of the correct nail 4 close to it.
By loosening the elastic sheet 2 using a screwdriver,
It is pushed back by the restoring force, and joint alignment can be performed easily and with high precision.

<Effects of the Invention> The present invention is as described above (a gypsum board is joined to the surface of a foamed concrete base via an elastic sheet, and this gypsum board is fixed to the base with pegs, so
It has superior workability compared to the conventional GL construction method, and
Since the space between the base and the gypsum board is closed with an elastic sheet, it improves sound insulation and prevents the gypsum board from tearing, which is the case with conventional partial adhesive bonding, and condensation due to temperature differences between the inside and outside.
This has the effect of eliminating problems such as water intrusion from outside wall joints all at once.
