Description

  TECHNICAL FIELD The present invention relates to a connecting structure for tubular members, and more particularly to a connecting structure for tubular members suitable for connecting a fence and a joint of a building.

Conventionally, when constructing a fence at a construction site, it has been necessary to carry out the main construction using an adhesive after performing a temporary construction for determining the dimensions and position of the fence in advance.
For this reason, it was necessary to disassemble the heel and the joint in a state where temporary construction was performed and apply an adhesive between the heel and the joint, and then reassemble the heel and the joint as the main construction. As a result, the assembly became a double work, leading to an increase in man-hours.

  Moreover, in the case of the working method which does not implement temporary construction, since it constructs simultaneously while apply | coating an adhesive agent, it becomes a simultaneous operation | work of adjustment and assembly | attachment, and work was complicated.

  In order to solve this, a connection structure described in Japanese Utility Model Publication No. 7-26456 is known as a connection structure using a joint in a rainwater fence of a building. In this joint, an adhesive inlet is provided at the joint inlet, and a concave groove is provided along the circumferential direction from the adhesive inlet of the inlet to the surface on the end side. It is the structure connected by the connecting path.

According to the fitting method using the joint, first, when the adhesive is injected from the injection port with the joint opening slightly inserted into the end of the flange, the injected adhesive passes through the communication path. And fill the ditch. At this time, by further inserting the insertion opening into the ridge, the ridge and the joint can be fixed by the adhesive filled in the concave groove.
Japanese Utility Model Publication No. 7-26456

  However, even in the case where the heel is connected using the joint described in the above (Patent Document 1), after the adhesive injected from the injection port fills the concave groove via the communication path, the insertion port is further placed in the tub. It is necessary to insert. For this reason, it was necessary to detach the heel and the joint once in the temporarily constructed state, and then inject the adhesive, and then insert and assemble the heel and the joint again as the main construction.

  Therefore, there is still a problem that work is complicated and man-hours increase.

  In addition, although it is rare, even if construction is performed to reduce the amount of adhesive applied to the minimum required amount, adhesive accumulates more than necessary due to variations in construction at the site, and contacts the inner surface of the kite. The resin sometimes swelled. Therefore, the outer side surface of the heel may be deformed and the strength of the heel may be reduced.

  Therefore, the present invention provides a tubular member connection structure capable of connecting the joint and the heel by injecting adhesive in the temporarily constructed state without disassembling the tentatively constructed heel and joint again. The purpose is to provide.

  In addition, the adhesive can be applied to a uniform thickness and the coating amount can be confirmed, so that excess adhesive is not biased and does not touch the heel, eliminating swelling, An object of the present invention is to provide a connecting structure for cylindrical members in which the strength of the heel does not decrease without deformation of the heel outer surface.

<Configuration of connection structure of cylindrical members>
Hereinafter, a first embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 1 and FIG. 2, the connecting structure of the cylindrical member of the present embodiment is inserted into the inside from the flange 1 (first cylindrical member) and the opening end 2 of the flange 1. It is the connection structure of the cylindrical member which connects the gutter joint 6 (2nd cylindrical member) which has the insertion connection part 5 joined to the inner surface 3 of the gutter 1 via the adhesive agent.

And the said joint 6 is provided with the insertion part 5 inserted in the inside from the opening end 2 of the said collar 1 on both sides on both sides of this flange part 7 between these flange parts.
Furthermore, an adhesive reservoir 9 is formed between the inner surface 3 of the pair of flanges 1 and the outer peripheral surface 8 of the insertion connecting portion 5 to form a predetermined gap in which the adhesive is uniformly filled over the entire circumference. Provided on the outer peripheral surface 8 of the insertion connecting portion 5 on both sides of the flange joint 6.

  Then, two holes 10 for communicating the adhesive reservoir 9 on both sides and the outer surface 7 a of the flange portion 7 are provided in two opposite outer surfaces 7 a on the diameter of the flange portion 7.

  Here, when the flange joint 6 is inserted and connected to the flange 1, the flange portion 7 has a convex shape composed of an outer surface 7a and two side surfaces 7b, and the two side surfaces 7b are parallel surfaces. Therefore, since the side surface 7b of the flange portion 7 and the opening end 2 of the flange 1 are in surface contact, the positioning of the flange joint 6 and the flange 1 can be ensured.

  At this time, since the adhesive reservoir 9 has a shape of a concave groove provided on the outer peripheral surface 8 of the insertion connecting portion 5 excluding the flange portion vicinity 15 and at least the distal end portion vicinity 16 of the insertion connecting portion 5, The outer peripheral surface 8 between the flange portion vicinity 15 and the tip portion vicinity 16 is in surface contact with the inner surface 3 of the flange 1. For this reason, the adhesive reservoir 9 is a space surrounded by the concave groove and the inner surface 3 of the flange 1. The depth of the concave groove is approximately 0 to 5 mm as a depth at which the ridge 1 does not swell and deform.

  At this position, the side surface 7a and the outer surface 1a of the flange 1 are flush with each other, so that there is no difference in appearance.

  Then, a portion 15a of the flange portion vicinity 15 corresponding to the communicating hole 10 spreads approximately 45 degrees on both sides so that the flange portion vicinity 15 continues from the hole 10 toward the adhesive reservoir 9. It is shaved.

  As shown in FIG. 3, an adhesive injection portion 17 having a square cross section with a length S of the width of the flange portion 7 as one side is formed at a height H on the outer surface 7 a of the flange portion 7. An injection hole 18 having a diameter T is formed at the center of the adhesive injection portion 17 so as to reach the vicinity of the bottom surface 9a of the adhesive reservoir 9 (concave groove).

  Further, the injection hole 18 is formed in a rectangular cross section having a width Mx and a height N in a direction perpendicular to the injection hole 18 so as to communicate with the adhesive reservoir 9. At this time, the bottom surface 20 of the lateral hole 19 and the bottom surface 9a of the adhesive reservoir 9 (concave groove) are formed so as to be at substantially the same level.

  In addition, the hole 10 formed by communicating the injection hole 18 and the lateral hole 19 is provided at two locations on the opposite outer surface 7a on the diameter of the flange portion 7, both of which have exactly the same structure. The other hole 10 is used for adhesive injection (adhesive injection part 17) and the other hole 10 is used for adhesive confirmation.

  Here, the material of the heel 1 and the heel joint 6 is made of a synthetic resin such as a hard vinyl chloride resin in consideration of weight reduction and corrosion resistance.

<Operation of connection structure of cylindrical member>
As described above, when the flange joint 6 is inserted and connected to the flange 1, the flange portion 7 is a convex shape including the outer surface 7a and the two side surfaces 7b, and the two side surfaces 7b are parallel surfaces. Therefore, since the side surface 7b of the flange portion 7 and the opening end 2 of the flange 1 are in surface contact, the positioning of the flange joint 6 and the flange 1 can be ensured. At this position, the outer peripheral surface 8 of the insertion connecting portion 5 and the inner surface 3 of the flange 1 are in surface contact, and the adhesive reservoir 9 becomes a space surrounded by the concave groove and the inner surface 3 of the flange 1.

  As shown in FIG. 4, the adhesive is injected from one adhesive injection portion 17 in a state where the heel 1 is inserted and positioned in the heel joint 6 without applying the adhesive. At this time, since the adhesive container nozzle 21 is pressed against the injection hole 18 of the adhesive injection part 17 without a gap, the adhesive does not leak out from the injection hole 18 and passes through the horizontal hole 19 from the injection hole 18. It is poured smoothly into the reservoir 9. The flow of the adhesive is indicated by arrows.

  As shown in FIG. 5, in the portion 15a of the flange portion vicinity 15, the flange portion vicinity 15 is shaved at about 45 degrees, so that the injected adhesive flows smoothly into the adhesive reservoir 9 without resistance. Can do.

  As shown in FIG. 6, the adhesive injected into the entire area of the adhesive reservoir 9 passes through the injection hole 18 from the lateral hole 19 of the adhesive outlet 17a, which is the other adhesive injection part, and is excessively bonded from the adhesive outlet 17a. The agent 22 flows out. At this time, the injection of the adhesive from the adhesive container nozzle 21 is stopped.

  As described above, the inner surface 3 of the flange 1, the outer peripheral surface 8 of the flange joint 6, the flange 1, the side surface 7 b of the flange portion 7, and the open end 2 of the flange 1 are in surface contact with each other. The space connecting the one adhesive injection portion 17, the adhesive reservoir 9, and the adhesive outlet 17a is a communication space with almost no resistance for the adhesive, so that the adhesive smoothly passes through this defined space. Flow and fill.

  Here, as described above, the depth of the concave groove of the adhesive reservoir 9 is approximately 0 to 5 mm, and is set to a depth at which swelling does not occur. Even if a slight gap exists between the inner surface 3 of the flange 1, the outer peripheral surface 8 of the flange joint 6, and the flange 1, the side surface 7 b of the flange portion 7, and the open end 2 of the flange 1, Compared with the gap, the resistance in the communication space is so small that the leakage of the adhesive from the slight gap hardly occurs.

For this reason, the adhesive can be uniformly applied to the adhesive reservoir 9 with respect to the inner surface 3 of the bag 1 and the excess adhesive 22 flows out from the adhesive outlet 17a by visual observation. The application amount can also be confirmed, and the excess adhesive is not squeezed out to the inner surface 3 of the ridge 1 so that the ridge resin does not swell. The strength of the scissors does not decrease. The joint and the scissors can be connected by injecting an adhesive in the temporarily constructed state without disassembling the temporarily constructed scissors and the joint.

  Furthermore, with this method, since the application is completed by one operation of pressurizing the adhesive container nozzle 21, the application time itself can be greatly shortened.

  Note that the length of the insertion connecting portion 5 in the insertion direction is formed in consideration of the length that the connection strength can be kept to the minimum. The surface area of the adhesive reservoir 9 is also formed in consideration of the area where the connection strength can be kept to a minimum.

  As mentioned above, although embodiment of this invention was described based on drawing, all said Example showed an example of this invention, and it cannot be overemphasized that this invention should not be limited to these. Absent.

  For example, a portion 15a of the flange portion vicinity 15 corresponding to the communicating hole 10 extends approximately 45 degrees on both sides so that the flange portion vicinity 15 continues from the hole 10 toward the adhesive reservoir 9. Although it is shaved, this angle may be set as appropriate. In addition, if the lateral hole 19 is formed in the flange portion vicinity 15 without cutting the flange portion vicinity 15, the reliability with respect to the leakage of the adhesive in the region along the side surface 7 b of the flange portion 7 can be further improved.

  The injection hole 18 may have a tapered hole shape, for example, corresponding to the shape of the adhesive container nozzle 21 to be used so that the adhesive container nozzle 21 can be pressed without a gap.

  The adhesive injection part 17 (height H) is formed so as to protrude from the flange part 7 of the flange joint 6, but the adhesive container nozzle 21 is high enough to fit the injection hole 18 of the adhesive injection part 17. You may make the agent injection | pouring part 17 and the flange part 7 into the same height.

  The cylindrical member connected to the insertion connecting portion 5 can be used for various things, and may be used for other connections between the eaves and the eaves (the side eaves). The present invention can be applied to a semi-cylindrical member in which the cylindrical member is not closed 360 degrees.

  Furthermore, the present invention can also be used for joining other tubular members, and can be used, for example, for connecting ordinary household water, air conditioning, and other piping paths. And it is applicable also to materials other than synthetic resins, such as hard vinyl chloride resin.

  Applicable adhesives can be either low viscosity adhesives or spray adhesives.
