Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a Kasagi joint device, and more specifically, to a Kasagi joint device, in which a plurality of Kasagi joints are provided, in which a vertical plate portion and a horizontal plate portion are formed in a U-shape, a Z-shape, etc. along the building frame surface. The present invention relates to a Kasagi joint device in which members are arranged in series and a joint member is interposed on the back side of an adjacent Kasagi member at an abutting portion.

(Prior art and its problems) Generally, a cap board provided on a building frame needs to be processed at the corners. For example, as shown in Figure 10, when arranging the Kasagi B at the corner of the parapet body A, it is either an out corner (a in the figure) or an inside corner (b in the figure). Depending on the shape, the upper surface of the cap B must be bent into a mountain or valley shape. Even if it is a draining frame C as shown in figure c, or not only at the corner of the horizontal part,
The same applies to a corner portion that continues from the horizontal portion B1 to the inclined portion B2, as shown in FIG. Therefore, conventionally, the caps attached to the corners of the parapets or gutter frames of buildings are formed by welding the abutting ends of a pair of diagonally butted caps at a predetermined angle. This is because if the welding process is not performed, rainwater will leak between the caps.

In this way, the direction in which the caps are bent at corners is not constant, so the butt angle of the caps must be determined and welded each time depending on the site situation, which is very time-consuming. I used to be.

Further, in the straight portion of the parapet frame, the joint member is manufactured by bending a single member along the inside shape of the cap, or by welding a plurality of members. However, since there are many different widths of the caps depending on the width of the parapet frame, the width of the joint members must also be processed to correspond to this width, which requires time and effort to bend and weld. However, there was a problem that there was a risk of deformation during transportation.

(Technical Problem of the Invention) A technical problem of the present invention is to solve the above-mentioned problems and to propose a Kasagi joint device that can be easily installed in accordance with the Kasagi dimensions.

(Means for Solving the Problems) In order to solve the above problems, the Kasagi joint device according to the present invention has a vertical plate portion and a horizontal plate portion formed in a substantially U-shaped or Z-shaped cross section along the building frame surface. In a Kasagi joint device in which a plurality of Kasagi members are butted and arranged in a row, and a joint member is provided on the back surface of the adjacent Kasagi member at the abutting portion, the joint member is attached to the back surface of each vertical plate portion at the abutting portion of the adjacent Kasagi members. It is composed of a longitudinal member for indoor and outdoor use with a substantially L-shaped cross section along It is characterized by connecting a vertical member and a horizontal member.

Further, the vertical member and the horizontal member may be connected by inserting an engagement piece formed integrally with the horizontal member into an engagement groove formed along the longitudinal direction of the vertical member.

(Operations and Effects of the Invention) As described above, according to the present invention, the joint member provided on the back side of the adjacent Kasagi members at the abutting portion is composed of a horizontal member and a vertical member, and moreover, The vertical member can be connected to the vertical member by inserting a connecting member into the engaging groove formed along the longitudinal direction, or by inserting an engaging piece integrally formed on the horizontal member into the engaging groove formed along the longitudinal direction of the vertical member. Since the horizontal members are connected to the horizontal members, the horizontal members and the vertical members can be formed by cutting them into dimensions that roughly follow the horizontal and vertical plate portions that make up the Kasagi member. do not need. Moreover, the joint member can be formed by inserting and connecting these horizontal members to the vertical member directly or via a connecting member, and does not require complicated operations such as screwing or welding. In particular, the processing of joint members at the corners of building frames used to be extremely troublesome, but this is now simplified. Furthermore, even if the width and height of the capacitors vary widely, it can be easily accommodated by simply cutting the length of the horizontal or vertical members accordingly and combining them into each shape. be able to. Furthermore, the joint member does not need to be manufactured in advance and transported to the site as in the past. The plate-shaped horizontal and vertical members can be assembled on site. Therefore, there is no bulk or deformation during transportation.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In the figure, reference numeral A indicates the parapet frame of the building. A Kasagi B is arranged on the parapet frame A. This Kasagi B is made up of a plurality of Kasagi members 1, 1, . The ends of the adjacent Kasagi members 1, 1 at the inside corner are cut at approximately 45 degrees, and both ends are butted and connected to form a nearly right-angled corner. In order to prevent rainwater, wind, etc. from entering between the end surfaces of the two consecutively installed capping members 1, 1, a joint member 2 is interposed on the back surface between the ends of both capping members 1, 1. There is.

The joint member 2 is a substantially L-shaped vertical member 2a, 2b for indoor and outdoor use that faces each other along the back surfaces of the inner and outer vertical plate portions 1a of both the capstone members 1 at the abutting portion.
and a horizontal member 2 along each horizontal plate portion 1b of the above-mentioned Kasagi member 1.
c, and is formed by integrally engaging the upper ends of the two vertical members 2a, 2b and both ends of the horizontal member 2c via a connecting member 3 formed in a substantially L-shape. There is. That is, in correspondence to the fact that the adjacent Kasagi members 1, 1 are butted and connected at approximately right angles, the two opposing vertical members 2a, 2b are bent at approximately right angles at the corners of the central portion of the substrate 4. An engagement groove 5 is formed along the longitudinal direction on the opposing surfaces of the parts. The horizontal member 2c has projecting edges 7, 7 formed upright on both ends of the substrate 6, and an engagement groove 8 formed along the longitudinal direction on the lower center surface, and is cut at both ends at a substantially right angle. And joint member 2
is integrally formed by engaging the coupling member 3 with the respective engagement grooves 5, 5, 8 of the vertical members 2a, 2b and the horizontal member 2c.

In addition, the connecting member 3, the vertical members 2a, 2b, and the horizontal member 2
By forming locking portions (not shown) that lock each other in the engaging portions of c with the respective engaging grooves 5, 5, and 8, the two will not become disengaged and will be securely integrated. be converted into

When connecting the adjacent Kasagi members 1, 1 by the joint member 2, the joint member 2 is arranged between the back surfaces of the connected ends at the corners of the adjacent Kasagi members 1, 1. . At that time, in each vertical member 2a, 2b and horizontal member 2c, the Kasagi member 1,
A sealing material 9 is attached to a portion facing the vertical plate portion 1a and the horizontal plate portion 1b of 1 by gluing or the like. As a result, the gap between the two Kasagi members 1, 1 is well sealed,
Rainwater that enters through this gap flows toward the inside of the building frame along the Kasagi slope and is discharged. Although the abutting ends of the Kasagi members 1, 1 are sloped low towards the inside, the horizontal member 2c can easily accommodate this.

Further, the above-mentioned connecting device can be applied to the projecting corner of the parapet frame A in the same manner as described above. In this case, the only difference is that the inclination of the abutting ends of the Kasagi members 1, 1 is opposite to that of the inside corner. Of course, it can be applied not only to corners but also to straight parts of building frames.

Similarly, even if building frame A is a draining frame,
As shown in FIG. 6, the joint member 2 is integrated by engaging the horizontal member 2c and the two vertical members 2a, 2b in a Z-shape via the connecting member 3 according to the shape of the back surface of the kasagi. Therefore, it is possible to deal with this.

Next, FIGS. 7 to 9 show another embodiment in which two capping members 1, 1 are connected at the projecting corner of the parapet frame A. In this embodiment, the joint member 2 consists of two vertical members 2a and 2b disposed on the inside and outside along the opposing vertical plate portions 1a of the Kasagi members 1 and 1, and a Kasagi member 1 engaged with the upper end portions of the two vertical members 2a and 2b. 1 and a horizontal member 2c along one horizontal plate portion 1b.

In this case, each vertical member 2a, 2b and horizontal member 2c
each consists of an inner member 10 and an outer member 11.
That is, the inner member 10 of the outer vertical member 2a is provided with an engaging groove 13 on the outer side of the end of the substrate 12 bent at a substantially right angle, and has a locking edge 1 parallel to the outer side of the central corner.
4 is formed protrudingly, and the outer member 11 is formed on the substrate 15.
is formed at a substantially right angle, and has an engaging groove 16 on the inside of its end and a locking groove 17 corresponding to the locking edge 14 on the inside of the corner. The inner member 10 of the inner vertical member 2b has an engagement groove 19 on the outside of the end of a substrate 18 bent at a substantially right angle, and a locking groove 20 on the outside of the central corner. is the board 21
is formed at a substantially right angle, and an engaging groove 22 is formed on the inside of the end, and a locking edge 23 corresponding to the locking groove 20 is formed protruding inside the corner.

A bent engagement piece 25 is formed at each outer end.
The outer member 11 is formed into a substantially flat plate shape, and like the inner member 10, both ends thereof are formed at right angles, and a bent engagement piece 26 is formed at each outer end.

The joint member 2 first locks the internal members 10 and external members 11 of the vertical members 2a and 2b with the locking edges 14 and 23 in the locking grooves 17 and 20, and then locks the internal members 10 and the external members 11 of the horizontal members 2c at both ends. Insert the engaging pieces 25, 25 into the engaging grooves 13, 19 of the inner member 10 of the vertical members 2a, 2b, and then insert the engaging pieces 26, 26 at both ends of the outer member 11 of the horizontal member 2c into the engaging grooves 13, 19 of the inner member 10 of the vertical members 2a, 2b. By inserting into the engagement grooves 16 and 22 of the external member 11, the inner and outer horizontal members 2c are engaged with the upper ends of the inner and outer vertical members 2a and 2b. The adjacent Kasagi members 1, 1 at the corners are the inner and outer members 10 of the vertical members 2a, 2b and the horizontal member 2c that constitute the joint member 2, respectively.
By inserting and sandwiching them between the caps 11 and 11, they are connected, and the gap between the caps 1 and 1 is well closed. In addition, in the connection structure of the above-mentioned Kasagi members 1, 1, in order to prevent the joint between the ends of each Kasagi member 1, 1 from opening, screws are installed in the internal material 10 of the joint member 2.
Preferably, it is fixed by means of fixing means 27 such as rivets. The external members 11 of the vertical members 2a, 2b hide the joints of the capboard members 1, 1, and not only prevent rainwater from entering, but also hide the fixing means, so that a good appearance can be maintained.

Note that when the corner is an inside corner, the outer member 11 of the horizontal member 2c is formed in an inverted V shape, and the inner member 10 is formed in an inverted V shape.
It may be formed into a letter shape or a flat plate shape. Furthermore, it is even better if a sealing material 9 is provided between the vertical members 2a, 2b, the horizontal members 2c, and the Kasagi members 1, 1. The case where the corner portion is as shown in FIG. 10d can be considered in the same manner as in the above example.

As mentioned above, the joint member 2 interposed between the adjacent Kasagi members 1, 1 is composed of the horizontal member 2c and the vertical members 2a, 2b, and the horizontal member 2c
The connecting member 3 is inserted into the engaging groove 5 formed along the longitudinal direction of the vertical members 2a, 2b, or the connecting member 3 is inserted into the engaging groove 1 formed along the longitudinal direction of the vertical members 2a, 2b.
The vertical member 2a and the horizontal members 2b, 2c are connected by inserting engaging pieces 25, 26 formed integrally with the horizontal member 2c into the horizontal members 3, 16, 19, 22. The horizontal members 2c and the vertical members 2a, 2b may be formed in a shape that roughly follows the horizontal plate portion 1b and vertical plate portion 1a that constitute the Kasagi members 1, 1.
Easy to process notches etc. Further, the joint member 2 connects these horizontal members 2c to the vertical members 2a, 2b directly by means of engagement pieces 25, 26 or by connecting them to the connecting member 3.
It can be formed by inserting and connecting through the connector, and does not require complicated work such as screwing or welding. In particular, processing the joint members 2 at the corners of the building frame was extremely troublesome;
This becomes easy. Moreover, even if the width and height of the capacitor vary widely, this can be easily accommodated by appropriately cutting the length of the horizontal member 2c or the vertical members 2a, 2b accordingly. . Furthermore, the joint member 2 does not need to be manufactured in advance and transported to the site, unlike the conventional method.
The plate-shaped horizontal member 2c and the vertical members 2a, 2b may be assembled on site. For this reason, the bulk during transportation,
There is no deformation etc.
