[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cross-sectional shape of a viscous substance such as a sealing agent or an adhesive agent, which has been determined in advance, on a preset coating surface of a plate glass for construction, a panel, and other various adherends, Even if the cross-section is particularly complicated, it is possible to accurately and continuously without air entrainment, and in some cases, to secure a sufficient coating pressure necessary for wetting the coating surface and to achieve continuous coating. Alternatively, the present invention relates to a viscous material application nozzle that can be applied intermittently.

2. Description of the Related Art Conventionally, since a plate glass or panel for construction has been cut into a desired size, it is necessary to attach it to a structure or to attach various members such as a sealing material. Adhesive may be applied. In this case, the sealing agent or the adhesive is usually applied by one of the following two methods. First, the first method is to apply a masking tape or a fixed-sized synthetic resin foam with glue to the outside of the coating surface of the adherend such as a plate glass or panel on which a preset sealing agent or adhesive is applied. After that, for example, by operating a manual gun, a sealing agent or a cylindrical nozzle provided at the mouth of a cartridge filled with a sealing agent or an adhesive attached to its retainer, or a nozzle of various other shapes is used to seal the sealant on the coated surface. Extrude the adhesive in a large amount in a proportional amount, squeeze the fixed-form synthetic resin foam to a uniform thickness with a spatula, etc. and scrape off excess sealing agent or adhesive to finish,
Finally, the masking tape and fixed-form synthetic resin foam are peeled off and removed. In addition, the second method is a simple but devised one, in which the end of the spatula is cut out according to the cross-sectional shape of the sealing agent or adhesive to be applied to the coating surface, and the coating surface and its outside After a large amount of the sealing agent or the adhesive is applied, the spatula is moved along the application surface to scrape off the excess sealing agent or the adhesive to finish.

[0003]

With these methods, the work of applying a sealant or an adhesive to a preset application surface of an adherend such as a plate glass or panel for construction is simple. If you have auxiliary materials, you can easily do it without choosing a place. However, these methods still have a problem that the sealing agent or the adhesive can be applied to the applied surface only in a very simple sectional shape. Also, not only is the work speed slow,
Since it is necessary to finish the work before the sealing agent or the adhesive agent extruded from the cartridge is solidified, the work becomes intermittent and there is a problem in efficiency. Further, it is also pointed out that a large amount of material is wasted because the sealing agent or the adhesive is largely extruded from the cartridge to scrape off the excess. In addition, there is a problem that a sufficient coating pressure necessary for wetting the surface of the viscous material to be coated cannot be secured.

On the other hand, for plate glass and panels for construction, conventionally, a method of cutting a plate material into a required size and simply fitting it into a frame material and mounting it has been adopted.
The air-tight and water-tight sealing function between the panel and the frame material includes sash frame and curtain wall frame using aluminum extruded shape materials that can be processed into complicated cross-sectional shapes, including the function of adjusting the fit due to the low cutting accuracy of flat glass and panel. Depends exclusively on. Then, the sealing agent is filled in the joint groove on site, for example, by operating a manual gun and through the nozzle of the cartridge filled with the sealing agent mounted on the retainer thereof. After filling the joint groove with a sealing agent, it is smoothed with a spatula. Thus, the sheet glass and the panel are finally sealed between the frame members.

However, recently, due to economical and design requirements, precast concrete, granite, other inorganic materials, metal plates, simple metal bending members and roll forming, which can be simplified or simply formed or processed, are used for frame materials. It is necessary to combine members to ensure high performance, and further between plate glasses,
In addition to directly combining panels with each other without using frame materials, after attaching plate glass and panels to the structure,
Assuming the development of a constant pressure drainage method joint that enables a so-called dry seal method, which is a completely preceding factory seal installation method that eliminates the need for on-site sealing work, and is mainly used for sheet glass and panels, assuming the improvement of cutting and finishing accuracy of sheet glass and panels. A more complex cross-sectional shape for air-tightness and water-tightness and a high degree of elasticity at the end, a high-strength, pre-molded synthetic rubber molding member or metal reinforcing member directly bonded, usefulness of configuring the joint function, Convenience has been recognized. These enable functionalization and sophistication of the end portion of a plate member such as a plate glass and a panel, particularly a plate glass, which has hitherto only acquired a simple end shape. In order to do so, first of all, a sealing agent or an adhesive with various cross-sectional shapes can be simply and efficiently used.
In addition, it is necessary to develop a method for precisely and simply coating the end portion of the plate member before attachment to a structure or the like and adhering necessary members by simple preparation in a factory or on site. The cross-sectional shape and size of the cross-section for applying the sealing agent or adhesive that is actually required is from several types to at least about ten types in a large-scale building, and the total length of each unit is 1000 meters. become. For this reason, even if some preparation is required, anyone can easily apply the coating work with ordinary skill and ordinary construction machinery and equipment without a large amount of preparation cost and great effort. Is required.

In view of such conventional problems and in response to the long-awaited future, the viscous material coating nozzle according to the present invention has been devised. Even if a viscous material such as a sealing agent or an adhesive agent has a predetermined cross-sectional shape, particularly a complicated cross-sectional shape, on the preset coated surface of the adherend, it does not involve air accurately and It is an object of the present invention to make it possible to carry out coating continuously or intermittently with a uniform thickness, or in some cases, by securing a sufficient coating pressure necessary for wetting the coated surface.

[0007]

In order to achieve such an object, according to claim 1 of the present invention, an adhering surface of an adherend for adhering a preset viscous substance and an outer side in the adhering direction of the viscous substance. Inside the nozzle body having a joining surface capable of surface joining, along the coating direction of the viscous material, a discharge port opening to the side end side corresponding to the coating surface and the joining surface side is provided at the starting end side, and the terminating end. The viscous material flow space is provided with a connecting portion for connecting to the cartridge filled with the viscous material on the side, and the viscous material flow cross section is formed in at least a part of the flow space from the cross-sectional shape of the connection portion A viscous material coating nozzle having a deformation path for deforming the cross-sectional shape similar to the cross-sectional shape was constructed. or,
According to another aspect of the present invention, the viscous substance is separately provided inside the nozzle body, which has the adhering face of the adherend for adhering the preset viscous substance and the joint surface capable of surface-adhering to the outside in the viscous substance applying direction. Along the coating direction, the discharge port is opened on the side of the side corresponding to the coating surface and the side of the bonding surface on the starting end side, and the connecting portion for connecting with the cartridge filled with the viscous substance on the terminal side. A viscous material flow space is formed, and at least a part of the flow space is formed with a deformation path for deforming the flow cross section of the viscous material from the cross-sectional shape of the connection portion to a cross-sectional shape similar to that of the discharge port. Constituted a viscous material coating nozzle in which a pressure-bonding edge for securing a coating pressure necessary for wetting the viscous material coating surface was formed on the side edge of the discharge port. Further, in claim 3, the cross-sectional area of the flow space of the viscous material is defined by the connection portion, the deformation path,
It is illustrated that the discharge ports are increased in order.

[0008]

Thus, such a viscous material application nozzle is used to apply a sealant or an adhesive to an adherend such as a building glass plate or panel. in this case,
The main body of the viscous material application nozzle is connected to the mouth of the cartridge filled with the sealing agent or adhesive by using the connection part, and the preset application of the adherend such as plate glass or panel is performed. Along the coating direction of the surface, the discharge port is placed at the starting end position with the connecting portion side facing the terminal end side, and the sealing agent or adhesive is extruded from the cartridge, and the sealing agent or adhesive that becomes the viscous substance of the nozzle body While press-fitting the sealing agent or the adhesive into the flow space, by moving the coating surface from the starting end side to the terminating side, the sealing agent or the adhesive is applied to the coating surface by the edge on the side end side of the discharge port. It is applied while being extrusion-molded into a predetermined cross-sectional shape. At this time, if a sealing agent or an adhesive agent is provided on the coated surface at the side edge of the discharge port with a crimping edge, the opening cross-sectional area becomes small, and the subsequent one is forced from behind. Due to the synergistic effect of being pressed against, the coating is performed while ensuring a sufficient coating pressure necessary for wetting the coating surface.
