JPH08302313A - Adhesive and floor substrate structure using the same - Google Patents

Abstract

PURPOSE: To obtain an adhesive which permits whether or not the adhesive has been applied to be quite obviously judged. CONSTITUTION: A phosphor is incorporated into a raw material for an adhesive, such as a naturally occurring product, a synthetic resin, or a synthetic rubber. Separately, a female screw portion 5 is provided in a through hole 4 provided in a floor substrate 3. A male screw portion 6 provided on the top of a supporting leg 2 is screwed into the female screw portion 5 to adjust the height of the floor substrate 3. In this case, the above adhesive is applied by coating or casting onto the female and male screw portions 5, 6 to fix both the portions to each other.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive and a floor base structure using the adhesive.

[0002]

BACKGROUND OF THE INVENTION Conventional adhesives are roughly classified into gelatin,
Natural products such as gum arabic, synthetic resins such as phenolic and epoxy resins, and synthetic rubbers. Further, a floor base provided at a predetermined height position from a concrete slab or the like is supported by support legs whose height can be adjusted, and after the height adjustment, the floor base side and the support leg side are fixed with an adhesive.

[0003]

The conventional adhesives and the adhesives used for the floor base structure flow into the male and female threaded portions, and thus the traces of application have been unclear. Further, when the application place is dark, it is extremely difficult to confirm the presence or absence of application even with a paste-like adhesive, and there is a disadvantage that application is forgotten when applying to a large number of sites.

Therefore, an object of the present invention is to provide an adhesive that makes it clear whether or not it has been applied, and a floor base structure using this adhesive.

[0005]

In order to achieve the above object, the present invention is one in which a fluorescent substance is mixed with an adhesive raw material such as a natural product, a synthetic resin or a synthetic rubber. In addition, it has a floor base structure in which a height adjustable support leg supports a floor base on a floor base such as a concrete slab, and a female screw portion is provided in a through hole formed in the floor base, and this female screw portion has a support leg. In the structure in which the height of the floor base can be adjusted by screwing the male screw portion formed on the upper portion, the above-mentioned adhesive is applied to or poured into the female and male screw portions to fix both portions.

[0006]

FUNCTION The location where the adhesive is applied is such that the phosphor absorbs ultraviolet rays and emits fluorescence after solidification, so that it is easy to find the location where application is forgotten.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

As an example of the adhesive according to the present invention, an adhesive containing a viscous liquid cyanoacrylate monomer as a main component and various auxiliary agents and fluorescent substances selected from rare earth metals and transition metal salts are selected. Inorganic substances were mixed and kneaded.
The fluorescent substance is a substance which emits light by adding a small amount of an activator to an organic substance in addition to hydrochlorides and sulfates of rare earth metals such as samarium, terbium, eurobium, gadolinium, and dysprosium, as well as calcium molybdate and calcium tungstate. It may be. Examples of organic substances include aromatic hydrocarbons such as benzene, naphthalene and anthracene, and phthalein dyes such as eosin and fluorescein. As the activator, copper, silver, gold, thallium, lead,
Heavy metals such as antimony and bismuth, transition metals such as chromium and manganese, rare earth metals, and organic substances having conjugated double bonds are used. As the luminescent matrix of the activated fluorescent substance, alkali halides, sulfides of Group II metals, oxyacid salts and the like can be preferably used.

As the main raw material of the adhesive, not only synthetic resins such as epoxy resin, phenol resin, cyanoacrylate monomer, urethane resin, silicone resin and acrylic resin but also natural products and synthetic rubbers can be used.

Next, a floor base structure using the above-mentioned adhesive according to the present invention will be described. As the floor base structure, as shown in FIG. 1, a floor base 1 such as a concrete slab is used to support a floor base 3 by supporting legs 2 whose height can be adjusted, and a through hole 4 formed in the floor base 3 Female thread 5
Is provided, and the male screw portion 6 formed on the upper portion of the support leg 2 is screwed into the female screw portion 5 so that the height of the floor base 3 can be adjusted. As the floor base 3, a panel having a predetermined size for the floor base is used, and a plurality of such panels are used for the floor base 1.
Configure them side by side. Through holes 4 are usually formed at four corners of such a panel, that is, the floor base 3. A male screw 8 is formed on the outer periphery of the cylindrical portion 7 provided with the female screw portion 5, and the male screw 8 is screwed into the through hole 4 of the floor base 3. A male screw 8 is formed not only on the upper portion of the support leg 2 but also on the lower portion thereof so that the support leg 2 can be screwed into the metal fitting 10. The metal fitting 10 is provided with a cushion rubber 11, and the cushion rubber 11 directly contacts the floor base 1.

A large number of floor base panels thus constructed, that is, floor bases 3 having support legs 2 at four corners are arranged on a floor base 1, and the support legs 2 are rotated in one direction from above the through holes 4. Adjust the height of the floor base 3. When the height adjustment is completed, the above-mentioned adhesive is poured from the through hole 4 as shown in FIG. Further, in this case, the height can be adjusted after the adhesive is applied to the male screw portion of the support leg 2 in advance. When 10 such floor bases 3 are laid out side by side, there are 40 through-holes 4 and the adhesive is poured into the respective places. If the adhesive is used, since the adhesive-applied portion emits light, it is possible to discriminate from a position above the through hole 4 where the adhesive is applied and where the adhesive is not applied. When it is confirmed that the adhesive has been applied to all the through holes 4, the finishing material 12 is attached to the floor base 3.

[0012]

As described above, in the adhesive of the present invention, the fluorescent material is mixed in the adhesive raw material such as natural product, synthetic resin, synthetic rubber, etc., so that the application point emits light after the application of the adhesive, Clarify the presence of adhesive. In addition, when such an adhesive is poured into the through holes of the floor base in the floor base structure, even if the number of the through holes is large, it is easy to find the part where the adhesive is forgotten.
