Description

[Detailed Description of the Invention] The present invention relates to an eave that protrudes from the eaves and is attached to the upper part of a window, and particularly relates to a roof support device for a small-scale eave.

The conventional structure for supporting the roof of an eave is to support the roof board with a girder through the upper roof, hiroko mai, and rafters, and the girder is supported by a brace attached with nails to a plywood receiving plate provided at the rear end of the eave. It was hot. Therefore, although the structure is complex, the weight of the roof is supported by the bonding force between the plywood support plate and the armrests.
The weak strength of the plywood backing plate and the weak connection with the arms made it difficult to withstand the heavy pressure of falling snow.

In consideration of these drawbacks, the present proposal has a simple structure for small-scale eaves, but its purpose is to increase the supporting force of the roof. It features a structure in which the plate to which the eaves are attached acts as a pillar to strengthen the force-bearing capacity, and by ensuring a secure connection between the rafters and the rafter hangers, it supports the roof without using girders or arms.

To explain the embodiment of this project based on the drawings, 1 is the roof plate of the eaves, which forms a slope forward from the rear end which is the side where it is attached to the building, and also slopes towards both side ends on both side parts. By doing so, the pressure of the roof on both sides is reduced.

Reference numeral 2 denotes an upper hat provided at the front and lower side peripheral edges of the roof board 1, which is laminated on the upper surface of the Hirokomai 3 and is provided for the purpose of giving a sense of solidity.

The Hiroko Mai 3 partially protrudes inward from the upper hat 2 to form a step with the upper hat 2, increasing the sense of solidity, and
A decorative veneer 4 serving as a ceiling plate for the eaves is stretched over the stepped portion.

5 is an auxiliary rafter, roof board 1 and decorative veneer 4
A plurality of pieces are inserted in the front-rear direction at appropriate positions in the space with a triangular side cross section created in between, and the roof board 1, upper hat 2, Hirokomai 3, and decorative veneer 4 are connected together to strengthen the roof part. .

Reference numeral 6 denotes a main rafter, the base of which is suspended horizontally in front of support columns 7, 7 erected at the rear ends of the left and right sides of the eaves, and fitted into the drill holes 10 of the rafter hooks 9, which are fixed with nails 8, etc. fixed,
It supports the front panel of Hiroko Mai 4. Also, rafter hanging 9
The upper end is adapted to abut and support the auxiliary rafter 5.

Reference numeral 11 indicates a plurality of small main holes interposed laterally in the gap between the decorative veneer 4 and the main rafter 6;
In addition to preventing the central part of the decorative veneer 4 from loosening,
It supplements strength and increases durability.

Reference numeral 12 denotes an arm rod that is in contact with the lower surface of the rear base of the main rafter 6, and is fixed to the rafter hook 9 with nails 13 or the like.
The supporting force of the main rafter 6 is increased. 14 is the main pillar of the building to which the support columns 7, 7 are attached, and 15 is the gable board attached to the rafters on both sides.

As mentioned above, the main project is 1 roof board, 2 upper hats, and 3 Hiroko Mai.
and main rafters 6 that support the roof part of the decorative veneer 4, etc.
However, the base end is fitted and fixed into the drilled hole 10 of the rafter hook 9, and the rafter hook 9 is fixed to the strong supports 7, 7, so it is not suitable for supporting a small-scale eave roof. In addition to being sufficient, since the arm rod 12 is provided which is in contact with the lower surface of the rear base of the main rafter 6 and is fixed to the rafter hook 9, the supporting force of the main rafter 6 is increased and the base end surface of the arm rod 12 is Since it is in contact with the rafter hook 9, it can sufficiently withstand the heavy pressure of the front surface of the roof, and is a new device that has a simple structure but has a sufficient supporting effect as a supporting device for a small-scale eave roof.

[Brief explanation of the drawing]

Figure 1 is a side sectional view of the proposed small-scale eave roof, and Figure 2 is a front view. Code: 1 is roof board, 2 is upper hat, 3 is Hirokomai, 4
1 is a decorative veneer, 5 is an auxiliary rafter, 6 is a main rafter, 7 is a support column, 9 is a rafter hook, 10 is a drilling hole, and 12 is an arm rod.

Claims (1)

[Scope of utility model registration request] The support columns 7, 7 to be installed on the main pillars of the building are erected in contact with the back side of the eaves, and the bases of the main rafters 6 of the eaves are horizontally fixed to the front surfaces of the support columns 7, 7. This roof support device for a small-scale eaves is characterized in that the arm rod 12 that abuts and supports the lower surface of the base side of the main rafter 6 is projected and fixed to the rafter hook 9.
