Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for engaging and fixing two sections together.

BACKGROUND OF THE INVENTION Recently, shapes with complex cross sections made of aluminum alloys and the like are often used as building materials. Although these shapes are sometimes connected by screws or welding, they are often fixed by engagement in order to improve the exchangeability and workability of parts.

Before explaining the gist of the present invention, the relationship of related members will be explained with reference to FIG. The external rim 3 is fixed on the outside side of the room, the glass plate 2 is applied to the indoor side edge of the external ram 3 via the tight material 4, and the rim 5 is further fixed on the indoor side of the mullion 1, so that the glass plate A sealing material 6 is filled between 2 and the ridge 5. Above mullion 1, external rim 3
The rims 5 and 5 are each made of a shaped material such as an aluminum alloy.

The reason for providing the external ribbed edge 3 is that it is manufactured separately from the main body of the mullion 1 and fixed afterwards because there are many holes and other processed parts in the external ribbed edge portion (shaded area).

Conventionally, in order to engage and fix the above-mentioned outer ledge 3 to the upright 1, as shown in FIG. 2, the outer ledge 3 is provided with an engagement groove 11' and an engagement groove 12', and the upright 1 is provided with an engagement groove 13' and an engagement groove 14' corresponding to the above-mentioned engagement portion.
The outer ridge or mullion is bent in the cross-sectional direction, and the elasticity of the engagement is utilized to engage the engagement groove 11' with the engagement groove 13', and the engagement groove 12' with the engagement groove 14'. However, since the dimensional accuracy of the cross-sectional shape of the mold material is relatively low, if the engagement length, i.e., the engagement allowance l, l', is small, the engagement is likely to come off during the glass fitting work, and if the engagement allowance l, l' is increased in anticipation of poor dimensional accuracy, the engagement becomes difficult. Furthermore, since the elasticity of the cross-sectional shape of the mold material is utilized, there is a drawback in that the cross-sectional shape is limited.

The present invention has been developed in consideration of the above-mentioned drawbacks, and the gist thereof is to provide an engagement fixing structure for two shapes that have corresponding engagement grooves and engagement strips and are engaged with each other. Engagement grooves that respectively engage with the engagement strips of the other profile are formed in one of the profiles, and both engagement grooves are opened in opposite directions in the same direction, and the engagement grooves are opened in opposite directions in the same direction. is fitted with an elastic material that resiliently abuts the edge and side surface of the engagement strip of the other shape member engaged in the engagement groove 11, and the repulsive force of the elastic material causes the engagement of the other shape member to This is an engagement and fixation structure of two shapes, characterized by tight engagement between the groove and the engagement strip.

The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 3 shows an improved engagement between the external ridge 3 and the mullion 1 in the curtain wall of the building shown in FIGS. 1 and 2. The external ridge 3 has openings in opposite directions in the same direction. Engagement groove 11,1
2, and the mullion 1 is provided with engagement strips 13 and 14 corresponding to the engagement grooves 11 and 12, respectively. Either one of the engagement grooves 11 and 12 of the external rim 3, for example the engagement groove 11, is formed into a large fitting groove S, and a rubber sponge or soft vinyl having a cylindrical cross section is inserted into the groove. The elastic material 15 is elastically fitted into the groove S. In addition, the engagement distances L and L' between the corresponding engagement groove 11 and engagement strip 13, and the engagement groove 12 and engagement strip 14 of the external rib 3 and mullion 1, respectively, are the engagement margins L and L' of the conventional structure described above. Each is made slightly larger than l′. When the external rim 3 and the mullions 1 are connected between the corresponding engagement grooves 11 and 13 and between the engagement grooves 12 and 14, the elastic material 15 is inserted into the mullions 1 within the grooves S. is pressed by the engagement strips 13, and the resulting repulsive force of the elastic material 15 causes the respective engagement portions to be closely engaged and fixed.

As described above, if the dimensional accuracy of the cross section of the shape material is not good, the elastic material 15 is replaced and adjusted. To this end, the length of the elastic material (that is, the length covering the entire width of the engaging portion or the use of a plurality of short pieces), the elasticity of the elastic material itself, the cross-sectional shape, etc. are changed.

In the above description, a fitting groove is formed in the engagement groove 11, but it may be formed in another engagement groove 12. It is also possible to form fitting grooves in the engaging portions of the ridge 5, but in the case of a ridge, this is usually unnecessary since the repulsive force of the tight material is applied to each of the engaging portions, resulting in loss of clearance.

Since this study is structured in this way, it has the following advantages.

(1) Even if the cross-sectional dimensional accuracy of the shape material is a little poor, it can be reliably installed due to the repulsive force of the elastic material.

(2) Since the elasticity of the two molded members is not utilized for engaging with each other, a large engagement margin can be provided, and the engagement will not come loose due to wind pressure vibrations. In some cases, molded members with high rigidity can be used.

(3) Free design is possible without restrictions on the shape of the shape material.
