Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a corner coupling device for fixing the inclined end surfaces of two members cut at an angle in a butt state using a corner block.

[Technical background of the invention and its problems]

As is well known, when both ends of two members with the same cross-sectional shape are cut at an angle and their slanted end surfaces are butted against each other and connected and fixed, a corner block is inserted across both members, and the members and the block are screwed together. but,
Due to the fact that the inclined end surfaces of the members to be butted against each other are rough due to the cutting process, and that there is a gap between the member and the block that is inserted into it, it is necessary to butt the inclined end surfaces of the members without any gaps. is very difficult,
A gap often occurred at the butt portion. Window frames that are attached to the outside of the room cannot be used if there is a gap between the butt parts of the frame members, so caulking has been applied to the butt parts of the frame members.

[Purpose of invention]

Therefore, this idea was devised to create a corner connecting device that provides a groove filled with caulking material in the corner block that is inserted across the two members, and fills the caulking material up to the abutting part and the screwed part of the two members. The purpose is to improve the fixation of members and the airtightness of abutting portions.

[Summary of the idea]

The corner connecting device of the present invention is a corner connecting device in which a corner block is inserted between two members having the same cross-sectional shape, and the two members are fixed by abutting their inclined end surfaces. A groove is provided, and an injection port is formed in a part of the groove that penetrates to the back surface, and a branch groove that communicates with the groove extends from the groove to the screw receiving part of the arm part opposite to the left and right of the bent part. The two members are fixed in an abutting state by a block that is fitted and fixed across the two members, and a caulking material that is filled into the concave groove and the branch groove from the injection port of the block.

[Example of idea]

Hereinafter, the structure of the corner coupling device according to the present invention will be explained based on the drawings of the embodiment. Reference numeral 1 is a member cut from a long light metal extrusion section, and member 1 is a partition between an inner wall 12 and an outer wall 13. An inward cavity 2 that spans the wall 11 and opens toward the front surface from the partition wall 11, and an outward cavity 3 that opens toward the back surface from the partition wall 11 are provided, and the end surfaces 1a of the member 1 are butted to form an angle θ. It is cut into 1/2 to form an inclined end surface 1a. 5 is two members 1 and 1' cut out from an extruded section.
The block 5 has arm parts 7 and 17 on the left and right sides of the bent part 6 which are fitted into the outward cavity 3 of the member 1.
are symmetrically protruded at an angle, screw receivers 8 and 18 are provided on both arm portions 7 and 17 that protrude toward the back side, and bent portions 6
A groove 16 is formed at least on the front side of the member, and from the inner peripheral side where the groove 16 is inscribed in the inner wall 12 of the member,
It is desirable to form an inlet 26 that penetrates to the outer peripheral side inscribed in the outer side wall 13 of the member, and has branch grooves 9 and 19 that reach from the concave groove 16 to the left and right screw receivers 8 and 18. Reference numeral 4 denotes a caulking material to be filled into the abutting portion of the two members 1 and 1'.The caulking material 4 is inserted across the two members 1 and 1' through the injection port 26 of the block 5, which penetrates to the back surface. It is filled between the block grooves 16 and between the branch grooves 9 and 19 that reach the screw receivers 8 and 18 from the grooves 16 and the two members 1 and 1'.

Since the angle coupling device of the present invention has the above structure,
A member 1 whose end face 1a has the same inclination angle is cut out from a long extruded member in advance, and a corner block 5 corresponding to the cross-sectional shape of the member 1 is separately formed.

First, from the bent portion 6 of the block 5, of the arm portions 7 and 17 arranged on the left and right, the left arm portion 7 is inserted into the outward cavity 3 from the inclined end surface 1a side of the member 1, and then the right arm portion 1 is inserted.
7 is inserted into the outward cavity 3' from the inclined end surface 1a' side of the separate member 1', and then both members 1, 1' are inserted into the block 5.
Screw the screws S into the screw receivers 8, 18 of the block arms 7, 17 from both members 1, 1', and then Either fix the left arm part 7 of the block 5 in an abutting state with the block 5, or first insert the left arm part 7 of the block 5 into the outward facing cavity 3 of the member 1, and screw the screw S into the screw receiving part 8 of the arm part 7 from the member 1. After fixing this, next, insert the right arm part 17 of the block 5 into the outward facing cavity 3' of the separate member 1', and screw the screw S into the screw receiving part 18 of the arm part 17 from the member 1'. Then, the two members 1 and 1' are fixed in a butt state.

By the above means, the inclined end faces 1a of the two members 1, 1',
1a' are abutted against each other and fixed, the injection port 26 of the corner block 5 fitted across the corner, that is, the butt part of the two members 1 and 1', is filled with caulking material 4 from the outside, and the caulking is applied. Insert material 4 into inlet 2
6 to the concave groove 16, and from the concave groove 16 to the branch grooves 9 and 1.
9 and fills the concave groove 16 and branch grooves 9 and 19 without any space. If there is a gap between the abutting portions of the two members 1 and 1', a part of the caulking material 4 filled in the groove 16 will flow into that gap and solidify.
A portion of the caulking material 4 filled in the branch grooves 9, 19 also flows into the gaps between the screws S screwed into the members 1, 1' and into the screw receiving parts 8, 18, and solidifies.

Incidentally, the angle connecting device of the present invention is not limited to the above embodiment, and the left and right arm portions 7, 1 of the block 5
7 and the inlet 26 provided in the concave groove 16 of the block bending part 6 are provided in two or more places, or the inlet 26 that penetrates the concave groove 16 is provided in the branch groove 9, 19. Even if it is provided, the same purpose is achieved, and the shape and structure of the bent portion 6 of the block 5 that is inserted into the outwardly directed hollow portion 3 of the member 1 and the arm portions 7 and 17 that are provided on the left and right sides of the bent portion 6 are in accordance with the gist of the present invention. It can be changed as appropriate as long as it does not violate the rules.

[Effect of idea]

Therefore, the corner connecting device of the present invention uses a corner block that is inserted across the abutting portion of two members, and a screw that is screwed into the block from the member to fix the inclined end surfaces of both members in abutting state, and also to The fixation of the two members is further strengthened because the caulking material is also filled in the concave groove provided in the bent portion of the body and the branch groove that communicates from the concave groove with the screw receiving portions of the left and right arms. Moreover, if there is a gap in the butt part, the caulking material filled in the groove will penetrate into that gap and solidify, so there will be no gap between the butt parts of the two parts, and the caulking material filled up to the screw receiver will also solidify. Since the material enters the gap between the screw screws and hardens, no gaps are created in the screw screws. As a result, it is possible to prevent water from seeping through the abutting portions of the two members and the screw threaded portions, thereby preventing corrosion of the members. In addition, the means for attaching the block to the two members is easy, and it is not only easy to fill the caulking material from the block to the abutting part, but also the angle of inclination of the leg parts on the left and right sides of the bending part of the block and the end face of the member are The angle connecting device of the present invention has the above-mentioned features such as being able to butt the two members at any angle depending on the inclination angle, which allows the two members to be tightly connected in an airtight state, and has beneficial effects in practical terms. play.
