Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixing structure for a horizontal member and a vertical member in an assembled structure.

[0002]

[Prior Art]

 Conventionally, as a fixing structure for a horizontal member and a vertical member in an assembly-type structure, two tap holes for tapping screws are provided at upper and lower ends of the horizontal member at predetermined intervals, and both ends of the horizontal member and the horizontal member are provided. It is known that the vertical members arranged at both ends of each are joined by two tapping screws.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional fixing structure of the horizontal member and the vertical member in the prefabricated structure, one end of the horizontal member and the vertical member are connected by two screws only when there is only one screw. This is because the lateral member easily rotates around the center.

The object of the present invention is to prevent the horizontal member from rotating about the screw even though one end of the horizontal member and the vertical member are connected by only one screw, and therefore the screw An object of the present invention is to provide a fixing structure for a horizontal member and a vertical member in an assembled structure that can reduce the number of screws and the screw mounting work by half.

[0005]

[Means for Solving the Problems]

 The fixing structure of the horizontal member and the vertical member in the assembled structure according to the present invention is provided with tapping screw pilot holes or screw holes extending in the length direction at both ends of the horizontal member, respectively. The vertical members arranged at both ends are provided with protrusions protruding over the entire length so that the outer walls of the end portions of the horizontal members are brought into contact with each other, and the horizontal member rotation preventing projections with which the inner walls of the horizontal members are brought into contact are provided. Thus, both ends of the horizontal member and both vertical members are connected with one screw.

[0006]

[Action]

 The fixing structure of the horizontal member and the vertical member in the assembled structure according to the present invention is provided with tapping screw pilot holes or screw holes extending in the length direction at both ends of the horizontal member, respectively. The vertical members arranged at both ends are provided with protrusions protruding over the entire length so that the outer walls of the end portions of the horizontal members are brought into contact with each other, and the horizontal member rotation preventing projections with which the inner walls of the horizontal members are brought into contact are provided. Since both ends of the horizontal member and both vertical members are connected with one screw, respectively, even though one end of the horizontal member and the vertical member are connected with one screw. A fixing structure for the horizontal member and the vertical member is obtained in which the horizontal member does not rotate around the screw.

In addition, in view of appearance, since the protrusion for preventing rotation of the horizontal member and the end portion of the horizontal member are hidden and only the protrusion formed over the entire length of the vertical member is visible, the assembled structure can be seen. It can be a good one.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In this specification, the front and rear and the left and right are based on FIG. 1, the direction facing left obliquely downward in FIG. 1 is referred to as the front, the opposite side is referred to as the rear, and the left and right toward the rear is referred to as the left and right. And

FIG. 1 shows an assembled greenhouse which is an example of a building to which the present invention is applied. The assembled greenhouse shown in FIG. 1 has a rectangular parallelepiped shape and has vertical members ( 1), the horizontal members (2), (3) and (4) and the front and rear lateral members (5), (6) and (7) passed between the vertical members (1). Each of the vertical member (1) and the horizontal members (2), (3), (4), (5), (6), (7) is made of an aluminum extrusion mold material.

A fixing structure of the vertical member (1) arranged on the left side of the rear surface of the greenhouse and the horizontal member (3) arranged in the middle of the left side of the greenhouse will be described with reference to FIGS. 2 and 3.

The lateral member (3) is a hollow member having a substantially rectangular cross section, and has an outer wall (8) and an inner wall (9). At the upper edge of the inner wall (9), a substantially L-shaped cross section having a right downward horizontal edge which is a tapping screw pilot hole (10) is formed so as to project leftward.

The vertical member (1) has a substantially L-shaped cross section with the opening facing outward, and has a first vertical wall (11) perpendicular to the left side of the greenhouse and a rear side of the greenhouse. And a vertical second vertical wall (12). A vertical member cover (17) having a circular cross section of about a quarter is fitted on the vertical member (1) from the outside. The left edge of the first vertical wall (11) is provided with a forward protrusion (13) over the entire length, and a rightward protrusion (14) is provided near the tip of this protrusion (13). Thus, an L-shaped lateral member contact portion is formed. The first vertical wall (1 1) of the vertical member (1) is further provided with a lateral member rotation preventing projection (15) that abuts the lower edge of the inner wall (9) of the lateral member (3) from the right side. ing. The protrusion (15) is formed by cutting the first vertical wall (11) of the vertical member (1) at a right angle and projecting the right angle portion toward the horizontal member (3). Then, by screwing one tapping screw (16) into the tapping screw pilot hole (10) of the horizontal member (3) from the hole (18) formed in the first vertical wall (11) of the vertical member (1). The one end of the horizontal member (3) and the vertical member (1) are joined together.

Since the lateral member (3) is sandwiched by the protrusion (13) and the lateral member rotation preventing protrusion (15), the lateral member (3) rotates about the tapping screw (16). I can't. Moreover, in appearance, only the protrusions (13) formed over the entire length of the vertical member (1) can be seen because the projections (15) for preventing rotation of the horizontal member and the ends of the horizontal member (3) are hidden. The built-in greenhouse can be made to have a good appearance because it is installed.

In the above embodiment, the horizontal member (3) arranged in the middle of the left side of the greenhouse was a hollow member having a substantially rectangular horizontal cross section, but the opening was formed in a channel shape having an inward protruding edge. It may be directed to the right, and in this case, the lateral member rotation preventing projection (15) is brought into contact with the inward protruding edge from the right side. Further, the vertical member (1) and the horizontal member (3) may be made of metal other than aluminum or synthetic resin. Furthermore, a screw hole other than the tapping screw can be used by forming a screw hole in the end portion of the lateral member (3).

【effect】

 According to the fixing structure of the horizontal member and the vertical member in the assembled structure according to the present invention, the horizontal member is screwed even though one end of the horizontal member and the vertical member are connected by only one screw. Since a fixed structure of the horizontal member and the vertical member that does not rotate around the center can be obtained, the number of screws is different from the conventional structure that connects one end of the horizontal member and the vertical member with two screws. And the screw mounting work can be halved.

Moreover, in view of appearance, the protrusion for preventing rotation of the horizontal member and the end portion of the horizontal member are hidden, and only the protrusion formed over the entire length of the vertical member is visible. It can be a good one.
