Description

  The present invention relates to a joining structure of cross members that intersect with each other, and more specifically, for example, in joining and assembling a metal lattice in a window frame with a lattice, Concerning structure.

  Conventionally, for example, in joining and assembling of metal bars in a window frame with a lattice, it is common to assemble the cross-joining portions of the crosspiece members with a fixing tool such as a screw.

  However, in the case of using this fixing tool, there are problems such as loosening due to poor tightening, rusting and the like, and further, the appearance of the fixing tool is poor because the fixing tool protrudes to the outside.

  The problem to be solved by the present invention is that, for example, the joining and assembling of the metal bars in the window frame with a lattice is performed by a fixing tool protruding outside such as a screw stopper.

  Therefore, the object of the present invention is to provide a grid-like joint assembly using metal bars in a window frame with a grid, for example, without using any fixing tool protruding outside such as a screw, and the cross-joint portion has an integral appearance, In addition, it is an object of the present invention to provide a joining structure for cross members that are joined together while preventing the cross members from being lifted.

  For this purpose, in the joining structure of intersecting beam members according to claim 1 of the present invention, symmetrical joining notch portions 3 and 4 are formed at the intersecting portions of the two beam members 1 and 2 intersecting each other. In addition, in the longitudinal direction of the one crosspiece member 1, an insertion hole 6 of the lifting prevention rod 5 is formed through the joint cutout portion 3, and the one crosspiece member 1 in the other crosspiece member 2 is formed. Insertion holes 7 that match the insertion holes 6 are formed on both side surfaces of the junction intersection with the joint, and the junction notches 3 and 4 of the two crosspiece members 1 and 2 are engaged with each other in a crossing manner. It is joined, and the lifting prevention rod 5 is inserted through the insertion hole 7 from the insertion hole 6 of the one of the crosspiece members 1, so that the rise of the joining crosspiece member is prevented. It is.

  According to the joining structure of crossing crosspiece members according to the present invention, the joining fixture is not visible from the outside, the joining portion is integral, the appearance is good, and the crosspiece member does not lift up, and has a high commercial value. For example, a window frame with a lattice can be provided.

  The best mode for carrying out the invention according to the present application will be described below together with its operation with reference to the drawings.

  FIG. 1 is a partially omitted exploded perspective view showing an example of a joining structure of crossing crosspiece members according to the present invention, and FIG. 2 is an exploded perspective view with partial omission in a state where crosspiece members are joined in a lattice shape. FIG. 3 is an enlarged cross-sectional view showing the cross-joint portion of the crosspiece member, FIG. 4 is a cross-sectional view showing another example of the crosspiece member, and FIG. 5 is a partially omitted exploded view showing a joining structure in another example of the crosspiece member FIG. 6 is a partially omitted exploded perspective view showing a lattice-like joining state in another example of the crosspiece member, FIG. 7 is a front view of a window frame with a lattice embodying the present invention, and FIG. 7 is a partially omitted enlarged sectional view along line 8-8 in FIG. 7, and FIG. 9 is an enlarged sectional view partially omitted along line 9-9 in FIG.

  In FIG. 1, the two crosspieces 1 and 2 are preferably made of metal such as aluminum, and U-shaped joint cutout portions 3 and 4 are formed symmetrically by cutout processing at the intersecting portions, and are shown by solid lines. As indicated by the arrows, the joint cutout portions 3 and 4 are joined to form a cross shape.

  In this way, the crosspieces 1 and 2 are joined in a cross shape or in a lattice shape as shown in FIG. 2, but the crosspieces 1 and 2 are made of metal so that they cross each other. Lifting occurs at the joint.

  Therefore, as a means for preventing the lifting, an insertion hole 6 through which the lifting prevention rod 5 is inserted through the joint notch 3 in the longitudinal direction of one of the crosspieces 1 penetrates and the other crosspiece is formed. Insertion holes 7 matching the insertion holes 6 are formed on both side surfaces of the joining intersection of the member 2 with one of the crosspiece members 1, and the joint notches 3 and 4 of the two crosspiece members 1 and 2 are mutually connected. In the joined state engaged in a cross shape, as shown by solid lines in FIGS. 1 and 2, a lifting prevention rod 5 preferably made of an aluminum round bar is inserted from the insertion hole 6 of one crosspiece member 1. Inserted through hole 7.

  Then, as shown in FIG. 3, the cross joint portion by the joint cutout portions 3 and 4 of the two crosspiece members 1 and 2 is integrally coupled by the lifting prevention rod 5, so that the crosspiece member 1 Lifting is prevented and a completely flat state is maintained in plan view.

  As shown in FIG. 4, the two crosspiece members 1 and 2 may be hollow bodies as long as the insertion holes 6 are provided in the longitudinal direction.

  4 and 5, the two crosspieces 1 and 2 are the same crosspiece having the joint notches 3 and 4, the insertion holes 6 penetrating vertically in the longitudinal direction, and the insertion holes 7 that match the insertion holes 6. It is formed as a member.

  This is because, in the case of manufacturing the window frame with lattice 10 shown in FIGS. 6, 7 and 8, the lattice body 13 is made of a combination of aluminum molds and is screwed to the window frame 12 to which the glass 11 is attached. Since many crosspiece members are used, the two crosspiece members 1 and 2 are formed as the same crosspiece member. Can also be used, and the lifting prevention rod 5 is also inserted from one crosspiece member 1 (from the lower insertion hole 6) or from the other crosspiece member 2 (from the upper insertion hole 6). Because it can.

  In the illustrated embodiment, the crosspiece members 1 and 2 are square pillars, but are not limited to this, and may be cylindrical bodies. Further, the intersection is a cross shape, but may be an oblique shape.

It is a partially omitted exploded perspective view showing an example of a joining structure of intersecting beam members according to the present invention. It is an exploded perspective view of a part omitted in the state where a crosspiece was joined in a lattice shape. It is an expanded sectional view which shows the cross junction part of a crosspiece member. It is sectional drawing which shows the other example of a crosspiece. It is a partially omitted exploded perspective view showing a joining structure in another example of a crosspiece member. It is a partially omitted disassembled perspective view showing a lattice-like joining state in another example of the crosspiece member. It is a front view of the window frame with a lattice which implemented the present invention. FIG. 8 is an enlarged cross-sectional view partially omitted along line 8-8 in FIG. FIG. 9 is a partially omitted enlarged cross-sectional view taken along line 9-9 in FIG.
