Description

[Detailed description of the invention] Industrial field of application The invention relates to a device for attaching horizontal members such as joists in sunrooms, balconies, and greenhouses between two attachment members such as joist hooks and girders. .

Prior art As a mounting device for joists on a balcony,
Place the joist across the joist hook and girder, insert the bolts provided on the joist hook and girder into the through holes in the joist,
It is known that a nut is screwed onto this bolt to tighten and fix the joist.

However, with this mounting device, the balcony
If wind pressure, earthquakes, the weight of a person (when a person rides on the vehicle), etc. cause the joists and the girder to twist, causing relative displacement in the longitudinal direction, or changing the distance between opposite sides, the relationship between the joist, the joist, and the girder may change. Unreasonable force may be applied to the connecting portion, resulting in damage.

In addition, if the distance between the joists and the girder differs from the specified value due to installation error, the bolts and the through holes may not match, and a new through hole must be drilled. Otherwise, the installation work becomes troublesome.

Purpose of the invention Even if the two mounting members facing each other are displaced relative to each other in the longitudinal direction or the distance between them changes, unreasonable force will not be applied to the connecting part of the cross member, and the distance between the two mounting members facing each other will not be applied. To provide a cross member mounting device capable of easily attaching cross members even if the cross members are different.

Structure of the device First and second elongated holes are formed at both longitudinal ends of the cross member, through which bolts for tightening and fixing are inserted, the first elongate hole is an elongated hole in the longitudinal direction of the cross member, and the second elongate hole is formed as a long hole in the longitudinal direction of the cross member. is a long hole in a direction perpendicular to the first long hole.

Embodiment FIG. 1 is a perspective view of a balcony, in which a side cap 3 and a lower side rim 4 are constructed across the left and right pillars 1, 1 and the left and right vertical frames 2, 2. A side lattice 5 is attached between the side lower furrow 4, and a front cap 7 and a front lower furrow 8 are constructed across the left and right pillars 1, 1 and the intermediate pillar 6. Kasagi 7
A front grille 9 is attached between the front lower body rim 8 and the lower front rim 8.

A joist hook 10 is installed across the lower portions of the left and right vertical frames 2, 2, and a girder 11 is installed across the left and right columns 1, 1 and the intermediate column 6.
A joist 12 is attached across the joists and the joist hooks 10.

In Fig. 1, 13 is the gable, 14 is the auxiliary post, 15 is the foot support, 16 is the lower body leg, and 17 is the cane.

Figure 2 is a perspective view of the joists, with upper, lower, left and right walls 1
2a, 12b, 12c, and 12d form a hollow elongated body with a rectangular cross section, and an extending piece 20 is integrally formed on the right wall 12d side continuously with the lower wall 12b. The portion is bent upward to form a protrusion 21, and first and second elongated holes 22, 23 are formed near both longitudinal ends of the extension piece 20, and the first elongated hole 22 is The second long hole 23 is a long hole in the longitudinal direction, and the second long hole 23 is in the width direction (direction perpendicular to the longitudinal direction).
It is a long hole.

FIG. 3 is a perspective view of the joist attachment part, and the joist hook 10 has a vertical piece 30 and a horizontal piece 31 to form a long body with an L-shaped cross section, and the horizontal piece 31 has a pair of hook pieces 32, 32.
are integrally formed facing each other to form an upward lip groove 33, and the upper surfaces 32a, 3 of the pair of hook pieces 32, 32
2a serves as a mounting surface for the joist 12.

The girder 11 includes a hollow elongated main body 35 with a rectangular cross section and a horizontal piece 36, and the horizontal piece 36 has a pair of hook pieces 3.
7, 37 are integrally formed facing each other to form an upward lip groove 38, and the upper surface 3 of the pair of hook pieces 37, 37 is
7a and 37a serve as mounting surfaces for the joists 12.

A head 40a of a bolt 40 is slidably fitted into each of the lip grooves 33, 38, and a threaded portion 40b thereof projects upward.

Then, the joist 12 is placed across the placement surface of the joist hook 10 and the placement surface of the girder 11, and the threaded portions 40b of each bolt 40 are inserted into the first and second elongated holes 22, 23. , by inserting the hole 42 of the rectangular backing plate 41 into the threaded portion 40b of each bolt 40, and attaching the extension piece 20.
and are connected and fixed by screwing together nuts 43, respectively.

The contact plate 41 contacts the right wall 12d of the joist 12 and the protrusion 21, and the first and second elongated holes 22, 23
is blocked.

Since it is like this, the first elongated hole 22 and the bolt 40
The threaded portion 40b of the bolt 40 can be relatively displaced in the longitudinal direction, and the second elongated hole 23 and the threaded portion 40b of the bolt 40 can be relatively displaced in the longitudinal direction.
Since the joist 12 and the girder 11 can be relatively displaced in the width direction at the joint between the joist 12 and the girder 11, the joist 12 and the girder 11 can be relatively displaced in the longitudinal direction of the joist 12, and at the joint between the joist 12 and the joist hook 10, the joist 12 and the girder 11 can be relatively displaced in the width direction. 12
and the joist hook 10 can be relatively displaced in the width direction of the joist 12.

Therefore, the balcony becomes twisted due to wind pressure, earthquakes, the weight of people, etc., and the joists 10 and girders 1
Even if the joists 1 and 1 are displaced relative to each other in the longitudinal direction or the distance between the opposing sides changes, no unreasonable force is applied to the connecting portion of the joists 12.

Also, due to installation errors etc., joist hanging 10 and girder 1
If the facing distance with 1 is different from the predetermined value,
Since the nut 43 can be adjusted in a loosened state, the joist 12 can be easily installed.

In addition, in the above embodiment, the case where the joist 12 is installed between the joist hook 10 and the girder 11 has been described, but it is also possible to install a horizontal member corresponding to the joist between two mounting materials corresponding to the joist hook and the girder. It can also be used when mounted on a stand.

Effects of the invention Even if the two mounting members facing each other are displaced relative to each other in the longitudinal direction or the distance between them changes, no unreasonable force will be applied to the connecting part of the cross member, and the distance between the two mounting members will be different. You can easily attach the cross members.
