Description

[Detailed description of the invention] This invention relates to a cantilever beam mounting structure for buildings, and its purpose is to
The purpose is to stably and firmly support a cantilever beam with a simple structure.

Conventionally, the cantilever beams of buildings were supported using mounting brackets, reinforcing devices, etc. on the columns, but in order to withstand the pressure of snow and wind, the structure was stronger than the support of inner beams.

The present invention relates to these improvements, and consists of a column, a beam holder having a cantilever holder on one side and an inner beam holder on the other side, and installed above the column; A cantilever beam provided with a mounting part to be attached to the cantilever receiving part of the beam holder, and an extension piece extending from the mounting part and attached to the inner beam holder of the beam holder, and the beam holder. This is a cantilever beam mounting structure for a building in which an inner beam having an attachment portion for overlapping attachment with the extending piece of the cantilever beam is assembled to an inner beam receiving portion of a metal fitting using a simple fastener.

Next, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a schematic front view of the building, in which three pillars 1 support cantilever beams 2, 2 and inner beams 3, 3 at both ends, and roof plate attachments 4 are attached to the beams 2, 3. The roof plate 5 is attached through the roof plate.

Figure 2 is an exploded perspective view of the mounting parts of the pillars, cantilevers, inner beams, etc. shown in Figure 1.
, holes 6 for attaching the beams 2 and 3 are provided.

The beam support fitting 7 attached to the column 1 consists of a horizontal piece γ1 and a vertical piece 7□.In the longitudinal direction of the beam, the first side is a cantilever support part 8, and the vertical piece 72 has a hole 8 for attaching the cantilever. ’ is set,
The other side is an inner beam receiving part 9, and a hole 9' for attaching the inner beam is provided in the vertical piece 72.

Further, a hole 10 is provided between the holes 8' and 9', which matches the hole 6 in the column when assembled.

The cantilever beam 2 has a channel-shaped cross section, and has a mounting part 11 on the first side that is attached to the cantilever support part 8 of the beam support fitting 7, and a vertical piece 2 □ that is inserted into the hole 8' of the beam support fitting when assembled. Matching hole 11'
are provided, and the beam support fitting 7 and the cantilever beam 2 are fixed with bolts 12 and nuts 12'.

The cantilever beam is provided with an extension piece 13 extending from the attachment portion 11 and attached to the inner beam receiving portion 9 of the beam receiving fitting.

The extension piece 13 consists of a lower horizontal piece 13□ and a vertical piece 132, and the vertical piece 13□ is provided with a shape 13' that matches the shape 9' of the beam holder 7 during assembly.

Also, the vertical piece 2 at the boundary between the mounting part 11 of the cantilever beam 2 and the extension piece 13
．． 13° is provided with a hole 14 that matches the hole 10 of the beam holder 7 during assembly, and the upper horizontal piece 22 has a notch 15 through which the bolt 4' fixed to the roof plate fixture 4 passes. It is provided.

The inner beam 3 has a channel-shaped cross section, and its end portion is a mounting portion 16 that is attached to the inner beam receiving portion 9 of the beam receiving fitting 7 by overlapping with the extending piece 13 of the cantilever beam 2, and the vertical piece 161 During assembly,
Hole 9' of beam support fitting 7 and hole 13' of cantilever beam extension piece 13
A hole 16' is provided to match the bolt 17 and nut 1.
At 7', the beam support fitting 7, the cantilever beam 2, and the inner beam 3 are fixed.

Further, a notch 18 is provided on the end face of the vertical piece 161, and a bolt 19 is inserted into the notch 18 of the inner beam 3, the hole 14 provided in the cantilever beam 2, the hole 10 of the beam holder 7, and the column 1. The column 1, the beam bracket 7, and the nut 20 inserted into the column 1 are connected to the hole 6 of the column 1.
The cantilever beam 2 and inner beam 3 are tightened and fixed.

In addition, a notch 21 is provided on the end face of the upper horizontal piece 162 of the inner beam 3, through which the bolt 4' fixed to the roof plate fixture 4 passes, and is pressed into contact with the notch 15 of the cantilever beam 2 during assembly. Then, a matching hole is formed, and the roof plate fixture 4 is fixed to the beams 2 and 3 using the bolt 4' and nut 22.

FIG. 3 is a perspective view of essential parts showing how the column 1, cantilever beam 2, and inner beam 3 are attached.

4th. FIG. 5 is a longitudinal cross-sectional view of main parts showing how the beams 2, 3, columns 1, roof plates, etc. are attached.

As described above, the present invention has a simple structure and is easy to assemble, and has the following effects.

Since the extending part of the cantilever beam and the mounting part of the inner beam are fixed together, the inner beam acts as a reinforcement against loads such as snow accumulation and wind pressure applied to the cantilever beam.

Therefore, the mounting portion of the cantilever can be reinforced without using extra complicated reinforcing metal fittings as in the past, and the cantilever can be more firmly supported.

In addition, regarding ease of assembly, first lay the pillar horizontally and attach the pillar, beam holder, and cantilever beam on the ground, then set the pillar upright.
It can be assembled by one person by temporarily placing the inner beam on the beam holder and tightening it.

Note that by increasing or decreasing the number of inner beams and columns, the length of the building can be made flexible.

As described above, the present invention can be effectively applied to easily assembled buildings made of steel plates, such as bicycle parking lots, garages, and storerooms.
