[Industrial applications]

 The present invention relates to an adhesive application device that can evenly apply an adhesive to a building board.

[0002]

[Prior art]

 Conventionally, when a building board, particularly a ceiling board, is attached to the ceiling surface, an adhesive is applied to the back surface of the ceiling board. For this purpose, a roller or brush application method is used. However, in such a coating method, since the coating position is not stable, the coating state is not uniform, and the adhesive strength varies within the plate, and the adhesive does not always work effectively. Since the unevenness is uneven, if the amount is too small, the adhesion will be insufficient, and if the amount is too large, the thickness of the adhesive will cause unevenness, which will cause misalignment and spoil the appearance. However, it is very difficult to apply evenly because there is a problem that it will be soiled, and that excessive use is uneconomical, and that careful application in consideration of the above will increase the work time. He relied on the skill of skilled craftsmen.

Recently, in order to simplify the construction, a sticking construction using only an adhesive without using nails or staples has been carried out. In this case, the application state of the adhesive is particularly large in this case. The above problems become more apparent.

【Example】

 Hereinafter, the present invention will be described in detail according to illustrated embodiments, but the present invention is not limited thereto. Example 1 FIG. 1 is a schematic front view of an example of the building adhesive coating device of the present invention. In the figure, the building adhesive application device (1) includes a tubular body (2) made of a thick stainless pipe and an adhesive introduction pipe (3) connected to the tubular body (2). It consists of

In this example, the tubular body (2) has a total length (l) set to about 300 mm, and a pair of guides (21) and (21) are provided at both ends of the tubular body (2) to close the ends. The outer surface (22) of the tubular body (2) is provided with four recessed grooves (23). The length of the tubular body (2) may be appropriately changed according to the width of the flat surface to be coated.

Each groove (23) has a depth (a) of 0.5 mm and a width (b) of 10 mm and is formed over the entire circumference of the tubular body. Further, one discharge hole (24) is formed in each of the concave grooves (23). As shown in FIG. 2, each discharge hole (24) is provided at a position θ ₁ = 35 ° forward from the vertical line (H). This position corresponds to the front side in the coating direction and near the coating plane. Also, each discharge hole (24) is provided at a position l ₁ = 15 mm from both ends of the tubular body (2) and at a position l ₂ = 90 mm between these discharge holes, and the hole diameter is set to about 1 mm. ing.

In the tubular body (2) having the above-mentioned structure, for example, after sealing both ends of a thick stainless steel pipe, four discharge holes (24) are formed at predetermined positions on the tubular body surface (22) at predetermined positions. It can be formed by cutting the discharge hole (24) to a depth of 0.5 and a width of 10 mm.

In this example, the adhesive introduction pipe (3) is a pipe body which is divided into two branches such that there are one inflow passage (31) and two outflow passages (32). The pipe (32) is connected so as to communicate with the tubular body (2). In this connection, as shown in FIG. 2, the introduction pipe (3) is connected so that the tubular body (2) is inclined forward by θ ₂ = 45 ° with respect to the vertical line (H). Has been done.

A pressing means (not shown) is connected to the inflow path (31) of the adhesive introduction pipe (3) via a hose (4). Adhesive supply means is used as the pressing means, and although its structure is not shown, it has a pump structure having an inflow pipe and an outflow pipe and two cams inside, and these two cams. By the continuous rotation of the adhesive, the adhesive introduced from the inflow pipe is pushed out from the outflow pipe.

Note that the coating device (1) described above is merely an example, and the shapes of the tubular body, the adhesive introduction tube, the guide, etc. may be appropriately modified within the scope of the technical idea of the present invention. As a specific configuration example, for example, a tubular body without a guide (see FIG. 3) may be used, and a groove formed on the surface of the tubular body does not extend over the entire circumference but is partially recessed (see FIG. 4). ), A large number of narrow concave grooves may be provided, or the introduction tube may be multi-branched accordingly (see FIG. 5).

The operation of the coating device (1) having the configuration shown in FIG. 1 will be described. For example, as shown in FIG. 6, the back surface of the building board (5) having a predetermined width is the application target plane (51), and both widthwise ends of this building board (5) are a pair of guides at both ends of the tubular body (2). (21) The applicator (1) is arranged such that it is sandwiched by (21) and the outer surface (22) of the tubular body is in contact with the flat surface (51) to be applied. At this time, each concave groove (23) of the tubular body (2) causes a uniform width (a) and length (b) between the application target plane (51) and the tubular body (2). (t) is formed according to the number of grooves (23).

When the pressing means is operated in this state, the adhesive is introduced into the introduction pipe (3) through the inflow passage (31), but the adhesive is branched at the branching portion and outflow passages (32). It is dispersed and introduced into the tubular body (2). By this dispersion, the adhesive is supplied into the tubular body (2) substantially uniformly and simultaneously in the axial direction.

The adhesive introduced all at once as described above is pressed by the adhesive continuously supplied from the pressing means, and each of the concave grooves (23) formed in the tubular body (2) is pressed. The same amount is extruded from the discharge hole (24) almost at the same time. In this case, since the discharge hole (24) is formed on the front side as described above, it is extruded into the space defined by the rising surface (25) of the concave groove (23) and the flat surface (51) to be coated, It is stored there (see FIGS. 7 and 8).

When a certain amount of the adhesive is extruded and stored, the tubular body (2) is moved forward by the introduction pipe (3). At this time, the tubular body (2) moves with its both end guides (21, 21) sandwiching both ends of the building board. Then, the adhesive stored in front of the movement is pressed and spread on the rising surface (25) of the concave groove (23), and the gap (t) formed by the concave groove (23) and the flat surface (51) to be coated. Will be able to dive through. Therefore, the adhesive layer (6) having a cross section approximately equal to the size of the gap (t) is formed straight after the tubular body (2) has moved (see FIG. 9).

[0026]

[Effect of device]

 According to the present invention, the adhesive layer can be applied and formed in a constant state on a constant plane to be coated without requiring skill. The time required for the adhesive application work can be greatly shortened to improve work efficiency, and the application amount can be set to an optimum amount, which is economical. Since the optimum amount of adhesive can be applied according to the size of the building board, it is possible to prevent the occurrence of unevenness and misalignment, and to prevent the adhesive from protruding from the joints of the building board after attachment. , Does not stain the surface of the building board. Further, by providing the guide, the coating work can be carried out more easily. Further, the coating device of the present invention is small and easy to carry, and if there is an adhesive supply means having a simple pump mechanism, it can be easily used at a construction site.
