Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a seal structure for a girder connecting portion in a roof connecting portion such as a connecting portion of a simple garage or a roof connecting portion of a passageway.

[Conventional technology]

The simple garage is a roof frame with a rafter laid horizontally between the left and right girders to form a roof, and columns on the left and right girders.

In order to connect a plurality of such simple garages, the girders constituting the roof frame may be butt-connected.

[Problems to be solved by the device]

If the girders of the roof frame are butt-joined as described above, rainwater will infiltrate from the joints and fall under the roof. Resulting in.

To prevent this, a sealing material may be provided at the butted portion of the girder, but since the girder is thin, it is very difficult to abut the sealing material through the sealing material, and rainwater cannot be reliably prevented from entering.

Therefore, an object of the present invention is to provide a seal structure for a girder connecting portion that can solve the above-mentioned problems.

[Means and Actions for Solving the Problems]

(1) A backup material is arranged across adjacent upper surfaces of the girder, and a seal receiver placed on the backup material is fixed to the upper surface of the girder with a screw, and a seal material is provided between the periphery of the seal receiver and the upper surface of the girder. Is attached so that rainwater can be prevented from entering the butt joints of adjacent girders.

(2) A seal receiver is placed on each adjacent upper surface of the girder via a backup material, and each seal receiver is fixed to the upper surface of the girder with a screw. A seal material is attached to each side edge of the girder and the top surface of the girder to prevent rainwater from entering the connecting part where adjacent girders are butted and connected at a predetermined angle. It was made to be more producible.

〔Example〕

As shown in FIGS. 4 (a), (b), and (c), a roof plate 4 is attached to a roof frame 3 in which rafters 2 are laid horizontally between left and right girders 1, 1 to form a roof 5, A column 6 is attached to the girder 1 to form a simple garage A, and adjacent girders 1 of the adjacent simple garage A are butt-connected to each other to connect the adjacent simple garage A.

As shown in FIG. 1, the girder 1 includes a lower plate 10 and a vertical plate 11 on one side.
A main body 14 having a hollow shape with the other side vertical plate 12 and the upper plate 13, an outer vertical plate 15 integrally provided on the one side vertical plate 11, and an outer vertical plate 15 and the one side vertical plate 11 integrally. With the connecting lateral plate 16 provided in the above, it becomes a shape having a trough portion 17 on the upper outer side, and a connecting back plate 18 is fixed by a screw 19 across the back surface of the connecting lateral plate 16 and the adjacent girders 1 are butted. It is connected.

A backup material 20 is arranged over the inner surface of the trough portion 17, and a seal receiver 21 is placed on the backup material 20 and fixed to the girder 1 with a screw 22.

The backup material 20 is formed of a sponge such as foamed chloroprene or foamed vinyl chloride into a rectangular frame shape having a predetermined width and along the inner surface of the trough portion 17, and has a seal receiving member.
Reference numeral 21 is a plate-like main body 23 having a cross-sectional shape along the inner surface of the trough portion 17, and a projection 24 is integrally provided on the back surface thereof. Both ends of the projection 24 are notched by the width of the backup member 20 to provide a seal receiving member. The backup force 20 is supported by the projection 24 to support the tightening force of the vinyl 22 of 21 to prevent the backup material 20 from being compressed and deformed too much, and a gap is formed between the plate-shaped main body 23 and the connecting horizontal plate 16.
The head of the screw 19 of the connecting back plate 18 does not interfere with the plate-shaped main body 23.

Then, the sealing material 25 is attached to both side edges and one edge of the seal receiver 21 and the inner surface of the trough portion 17 so that rainwater does not enter the abutting portions of the girders 1.

As shown in FIG. 2, a roof plate 4 is attached across the end rafters 2 of one roof frame 3 and the end rafters 2 of the other roof frame 3, and the edge of the roof plate 4 has a third edge. Seal as shown
It projects to the upper surface of the other end edge of 21 and is held by a girder attachment 26.

The roof plate 4 is held against the upper surface of the rafter 2 by a rafter cover.

As shown in FIG. 5, the backup material 20 is formed into a wide single piece, and the notch 27 into which the backup material 20 is fitted is formed in the protrusion 24 of the seal receiver 21, and the plate-shaped body 23 of the seal receiver 21 is used as the backup material. 20 may be pressed and held.

Further, when connecting the roofs 5 at a predetermined angle as shown in FIG. 6, the roofs 5 are connected via a plurality of triangular roofs 5, and the girders 1 of the triangular roofs 5 are connected via the connecting girders 30. The seal girder 30 and the girder 1 are connected to each other, and the seal receiver 21 is attached to the connecting portion of the connecting girder 30 and the girder 1 via the backup material 20 as described above, and the seal material 25 is mounted.

In this case, at the inner corners, as shown in FIG. 7, the girders 1 become short and are sequentially butt-connected at a predetermined angle. Therefore, the backup materials 20 are arranged on the adjacent girders 1, respectively. A seal receiver 21 is placed on each backup member 20 and fixed by a screw 22, and a seal member 25 is provided between one side edge and one end edge of each seal receiver 21 and between the opposite side edges of an adjacent seal receiver 21. May be attached.

[Effect of device]

(1) Since the sealing material 25 is mounted over the upper surfaces of the adjacent girders 1, it is possible to reliably prevent rainwater from entering the butt joints of the adjacent girders 1.

(2) Since the seal receivers 21 are fixed to the upper surfaces of the adjacent girders 1 via the backup members 20, respectively, even if the adjacent girders 1 are butt-connected at a predetermined angle, rainwater will infiltrate into the butt-coupling portion. It is not necessary to make the seal receiver 21 into a shape that matches the connecting angle of the girder 1, and it is sufficient to cut the same shape of the shape member according to the connecting angle. it can.
