Description

  The present invention relates to a panel joining structure.

  It is known that a panel, which is a building material, is joined to another panel at an end face to constitute a wall, ceiling, floor, or the like of a building such as a warehouse or a container. For example, as shown to Fig.19 (a), the panel 1P is mutually joined when the collar part 11P and groove part 12P which were formed in each end surface along a longitudinal direction mutually fit (refer patent document 1). . Or as shown in FIG.19 (b), the panel 1P is mutually joined, when the groove part 12P formed in each end surface fits with each one columnar connection member 13P (patent document 2). reference). The panels joined to each other as described above can prevent the displacement between the panels in the direction perpendicular to the main surface (thickness direction).

  A plurality of joint tools 2 having the same shape are fixed to the first joint surface 10A. As shown in FIGS. 2A to 2C, the connector 2 includes a pair of plate-like hooks 21 that are parallel to each other and a belt-like connecting portion 22 that connects the pair of hooks 21 at both side portions along the longitudinal direction. And have. The joint 2 is integrally formed by bending a single metal plate patterned into a predetermined shape at two locations, for example, and a pair of hooks 21 and a connecting portion 22 are formed by two lines at the bent locations. Separated from.

  The pair of hooks 21 are formed so as to face each other with mirror image symmetry, for example. Each of the pair of hooks 21 is generally formed in an inverted J shape. The hook 21 extends from the side part opposite to the side part connected to the connection part 22 among the belt-like root part 23 extending along the connection part 22 and one end side (upper end side) in the longitudinal direction of the root part 23. Each has a tip portion 24 that protrudes at a right angle toward the other end side (lower end side). In the tip portion 24, a region toward the root portion 23 is formed with a notch 25 that opens downward. Moreover, the front-end | tip part 24 has the inclination part 26 formed in the edge part by the side of the root part 23 so that the distance from the root part 23 might become large, so that it went to the lower part.

  According to the panel joining structure according to the second embodiment, the hook 21 is fixed to the hole 3, so that not only the displacement in the direction perpendicular to the main surface of the first panel 1C and the second panel 1D, Deviation in the direction along the main surface can also be reduced. Moreover, it can reduce that the sealing and coating performed between the 1st panel 1C and 2nd panel 1D peel due to shift | offset | difference.

  In addition, according to the panel joining structure according to the second embodiment, construction is possible from a direction perpendicular to the main surface of the panel even when there is little space for construction in the lateral direction along the main surface of the panel. Therefore, the work cost can be reduced.

-Modification-
As shown in FIG. 14, the first panel 1 </ b> C may be formed with a second joint surface 10 </ b> E similar to the second joint surface 10 </ b> D at the end opposite to the first joint surface 10 </ b> C. Thereby, the some 1st panel 1C can be continuously joined in each 1st joint surface 10C and the 2nd joint surface 10E.

  Moreover, you may employ | adopt other building materials, such as a pillar material which has the joint surface similar to 10 C of 1st joining surfaces or 10D of 2nd joining surfaces as a panel of joining object. For example, the first panel 1C may be bonded to the second panel 1F having two second bonding surfaces 10F orthogonal to each other, as shown in FIG.

(Third embodiment)
As shown in FIG. 16, the panel joining structure according to the third embodiment of the present invention includes a first panel 1 </ b> A having a plurality of joining tools 2 a fixed to the first joining surface 10 </ b> A, a plurality of pressing portions 101, and the like. It differs from 1st Embodiment by the point provided with. Configurations, operations, and effects that are not described in the third embodiment are substantially the same as those in the first and second embodiments, and are omitted because they overlap.

  The connector 2a includes a pair of hooks 21a and a connecting portion 22 that connects the pair of hooks 21a. The hook 21a includes a root portion 23 and a tip end portion 24a protruding so as to bend at a right angle from a side portion opposite to the side portion connected to the connecting portion 22 to the lower end side of the upper end side of the root portion 23. Have each. The tip portion 24a has an inclined portion 26a formed at the end portion on the side of the root portion 23 so that the distance from the root portion 23 increases toward the lower portion. The inclined portion 26 a extends linearly until reaching the root portion 23.

  The pressing part 101 is a protrusion formed on the surface of the first joint surface 10A. The height of the pressing portion 101 with respect to the first joint surface 10A is formed higher than the height of the root portion 23 with respect to the first joint surface 10A. The pressing part 101 is formed of, for example, an elastic material and is bonded to the first joint surface 10A.

  The first panel 1A is arranged so that each tip portion 24a faces the corresponding hook insertion portion 31, and is moved in the insertion direction P from the first joint surface 10A toward the second joint surface 10B by the installer. Thereby, each front-end | tip part 24a is inserted in the corresponding hook insertion part 31, respectively.

  As shown in FIG. 17, the first panel 1 </ b> A is moved in the press-fitting direction Q from the hook insertion portion 31 toward the hook fixing portion 32 by the builder with each distal end portion 24 a being inserted into the hook insertion portion 31. The As the hook 21a moves downward with respect to the hole 3, each tip portion 24a is press-fitted into the hook fixing portion 32, and the insertion direction P (in the depth direction of the hole 3) by the inclined portion 26a and the hole 3. ). The pressing portion 101 presses the second joint surface 10B while the hook 21a is guided in the insertion direction P by the inclined portion 26a.

  According to the joint structure of the panel according to the third embodiment, the hooks 21a are mutually connected in the direction along the insertion direction P by the pressing portion 101 and the inclined portion 26, in addition to the tip portions 24a being sandwiched between the hook fixing portions 32. When the force acts, each of the holes 3 is firmly fixed. For this reason, according to the panel joining structure according to the third embodiment, the hook 21a is more firmly fixed to the hole 3, thereby being perpendicular to the main surfaces of the first panel 1A and the second panel 1B. Not only the shift in the direction but also the shift in the direction along the main surface can be further reduced. Moreover, it can reduce that the sealing and coating performed between the 1st panel 1A and the 2nd panel 1B peel by a shift | offset | difference.

(Other embodiments)
As described above, the present invention has been described according to the first to third embodiments. However, it should not be understood that the description and drawings constituting a part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples and operational techniques will be apparent to those skilled in the art.

  For example, in the first to third embodiments already described, the pair of holes 3 is not limited to slits parallel to each other, and as shown in FIG. It may be a hole 3b. The pair of holes 3b includes a pair of hook insertion portions 31b that are parallel to each other and a pair of hook fixing portions 32b that are formed so as to be separated from each other toward the bottom. As in the first to third embodiments, the hole 3b can firmly fix the hook 21 by being press-fitted into the hook fixing portion 32 after the tip portion 24 is inserted into the hook insertion portion 31. . Or a pair of hook fixing | fixed part 32b may be formed so that it may mutually approach, so that it goes below.
