Description

[Detailed explanation of the idea] This invention relates to a girder material for terrace roofs.

Conventional terrace roofs are not built very sturdily, so when snow falls on terrace roofs in snowy regions, they are often unable to withstand the snow load and break.

It is known that girder members are hung horizontally between the pillars to withstand the snow load applied to the roof, but the conventional method has problems with the connection structure between the girder members and the roof, and it is easy to There was a drawback that quick connection was not possible.

This idea was devised with a focus on the above points, and was designed to create a sturdy terrace roof girder that can be easily connected to roof structural members and that allows the roof to sufficiently withstand snow loads. The purpose is to provide.

Embodiments of this invention will be described below based on the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a terrace roof, which is provided on a terrace T via supports 2, 2.

The terrace roof 1 has a roof plate 3 and a frame F that surrounds and supports the roof plate 3.

The frame F includes a rear frame 4 and left and right side frames 5 fixed to the building frame.
6 and a front frame 7.

In Fig. 2, 8 is a rafter which is a roof structural member;
It is fixed to the upper end of the support column 2 via a bracket 9.

In the same figure, the front frame 7 shown in cross section includes a front frame main body 7a, a channel-shaped rafter attachment part 7b provided at the lower rear end of the front frame main body 7a, and a front frame main body 7a. Part 7a
It has a roof plate abutting part 7C provided at the upper end and a locking part 7d bent downward from the rear end of the roof plate abutting part 7C.

The front end of the rafter 8 is fixed to the rafter attachment part 7b by Pole)B and Nara)N, and the roof plate 3 is fixed and fixed by the roof plate fixing hook 10 being fixed to the locking part 7d. has been done.

Reference numeral 11 denotes a reinforcing beam member according to this invention, which holds and reinforces the lower surface of the rafter 8 and is attached to the upper part of the front end surface of the columns 2, 2.

The reinforcing girder 11 has a substantially rectangular cylindrical shape, and has a slope-shaped support part 12 on the front part of its upper end surface that abuts and supports the lower surface of the rafter 8, and a connecting part for connecting the rafter 8 on the rear part of its upper end face. It has 14.

Since the rafters 8 are installed at an angle, the support section 12 that supports the rafters 8 has an inclined surface, but the bracket connecting section 14 has a horizontal surface.

As a result, the horizontal part of the upper loco-shaped bracket 13 can be stably placed on the connecting part 14, the bracket and the hole in the connecting part can be easily aligned, and the screws can be tightened to form the bracket reinforcing girder. can be fixed to.

Since the bracket 13 is open upward, the rafter 8 can be easily fitted into the bracket 13 from above, and the rafter can be easily fixed with bolts and nuts.

In addition, since the support portion 12 is constituted by an inclined surface, the support area of the rafter can be increased, and a large support strength can be exhibited against the snow load.

Furthermore, since the connecting portion 14 is configured as a horizontal surface, the brackets and screws do not get in the way of supporting the rafter with the supporting portion 12.

Reference numeral 15 denotes a mounting groove provided in the longitudinal direction of the rear surface of the reinforcing beam member 11 facing the columns 2, 2.

A screw receiving plate 16 is slidably attached to the mounting groove 15,
The screw receiving plate 16 can be freely moved according to the installation position of the support column 2.

A screw hole 17.17 is bored in the screw receiving plate 16, and by tightening the screw holes 19, 19 into the screw hole 17.17 through the insertion hole 18.18 provided at the upper end of the support column 2. A reinforcing beam 11 is fixed to the column 2.

Therefore, in order to attach the reinforcing beam member 11 to the column 2, it is sufficient to move the screw receiving plate 16 to the entire surface of the column 2, insert the bolt 19 into the insertion hole 18 and the screw hole 17, and tighten the screw.

Reference numeral 20 denotes a protrusion that serves as a handle for moving the screw receiving plate 16 along the mounting groove to the support post 2, and 21 represents a positioning protrusion that locks the screw receiving plate 16 to the support post 2.

22 is a reinforcing plate (Pol) 19.19 is a reinforcement plate
Fix it to the rear end surface of.

A bracket 23 is fixed to the upper part of the front end surface of the column 2 as a girder holder that holds the reinforcing beam 11. By placing and holding the reinforcing beam 11 on the brackets 1 to 23, the reinforcing beam 11 is attached to the column 2. This results in more secure retention and fixation.

The screw receiving plate 16 may be simply fitted into the mounting groove 15 at right angles and fixed, and may not be able to slide.

Further, the screw receiving plate may be attached to the side surface of the beam member 11 in advance with screws.

Note that 24 is a main end cap that closes the end 25 of the reinforcing beam 11 (FIG. 4).

As described above, according to this invention, firstly, the reinforcing girder material has a support part consisting of an inclined surface in the front part of the upper end surface, and the roof structure material is supported by contacting with this support part, so that the support area is reduced. big,
High support strength.

Second, the reinforcing member has a connecting portion formed of a horizontal surface at the rear of the upper end surface, and the upper interlocking bracket is placed on the connecting portion at the horizontal portion and is screwed into place. can be fixed easily and quickly, and rafters can be fitted to the brackets and connected easily with bolts and nuts.

Thirdly, since the shape of the reinforcing beam is simple, it can be produced at low cost.
