Description

[Detailed Description of the Invention] This invention relates to an auxiliary post support for connecting the lower end of an auxiliary post erected on the upper surface of a beam to a beam in a prefabricated balcony.

A prefabricated balcony consists of multiple pillars erected from the building at predetermined intervals, a pair of left and right side beams installed between the pair of pillars located on both left and right sides and the wall of the building, and each pillar. The front beam installed between the
It consists of a large number of joists installed at predetermined intervals between the front beam and the wall of the building, decking material laid on top of these joists, and a cap and fence unit. It consists of a beam and a handrail fence erected along the front beam, and auxiliary columns are erected on the upper surfaces of the side beams and front beam as means for supporting the handrail fence.

However, the beams used in prefabricated balconies, such as side beams and side beams, are designed to exhibit high strength against loads mainly from above, and are usually designed with a cross-section in consideration of saving material costs. It is formed in a vertically long shape. For this reason, even if the auxiliary support struts installed on the top of the beam can be firmly fixed against loads acting from the vertical and horizontal directions, it is necessary to give up on saving material costs for the beam and use the auxiliary support support. Unless you use a beam with a sufficient front-to-back width for the front-to-back width, it is difficult to securely fix the beam against loads acting from the front and rear directions, and the beam itself may be twisted when loads are applied from the front and rear directions. occurs,
Accidents may occur in which the auxiliary column sways, which causes the handrail fence supported by the auxiliary column to sway, or the lower end of the auxiliary column comes off.

In view of this point of view, this invention is designed so that an auxiliary support for erecting an auxiliary support on the top surface of a beam can be connected not only to the beam itself but also to other members connected to the beam, such as joists and connecting members. , thereby providing an auxiliary post support for a prefabricated balcony that can solve the above-mentioned problems all at once.

The auxiliary column support 1 of this embodiment is erected on the upper surface of the front beam 5, as shown in FIGS. 3, 4, and 5, which show the cross section of section A in FIG. A flat plate part 11 with which the lower end of the auxiliary support column 9 having a rectangular cross-section and an open lower end abuts against each other;
The auxiliary support 9 is provided to protrude upward from the upper surface of the
A connecting piece 12 is inserted into the lower end of the flat plate part 11 and connected by a screw 16, and a connecting piece 12 is connected to the vertical wall 5a of the front beam 5 by a bolt and nut 17, which projects downward from the lower surface of the front end of the flat plate part 11. the first leg piece 13, and the joist 7, which protrudes downward from the lower surface of the rear end of the flat plate part 11 and whose end is connected to the front beam 5 via a horizontal part 15 formed at the lower end. A second leg piece 1 connected to the upper surface by a bolt nut 17
4, and this auxiliary post support 1 is attached to cover the upper part of the front beam 5.

The front beam 5 has flange portions 18a, 18b near the upper and lower ends of the vertical wall 5a, respectively, and a flange portion 18a, 18b protrudes from the lower end in the same direction as the protruding direction of each flange portion 18a, 18b to hide bolt heads and nuts. The lower flange portion 18b has a projecting edge 19 that
The end of the joist 7 is placed on the upper surface of the joist 7, and the bolts and nuts 17 are used to connect the two, and between the upper flange portion 18a and the upper surface of the joist 7, there is a side edge of the deck material 8 laid on the upper surface of the joist 7. The space is such that there is enough space for the part to be inserted.

In the area where the auxiliary post holder 1 is attached, the second leg piece 14 of the auxiliary post holder 1 obstructs the side edge of the decking material 8 between the upper flange 18a of the front beam 5 and the joist 7. Since the deck material 8 cannot be inserted between the two, a notch 20 is cut in the side edge of the deck material 8 at this part, and the gap created by this notch 20 is filled with a deck material attached to the lower end of the auxiliary support column 9 with a screw 16. It is designed to be covered and hidden by a material presser 21.

Next, FIGS. 6 and 7 are enlarged views of part B in FIG. 2 with the joists 7 and decking materials 8 omitted, and show the upper surface of the side beam 4 having the same cross-sectional shape as the front beam 5. An auxiliary column 9 is erected near the wall surface 2 of the column with the auxiliary column support 1 interposed therebetween. The end of the side beam 4 is attached to a wall 24 having an L-shaped cross section and attached to the wall surface 2 by a coach screw 23 via a wooden spacer 22, and a wall connected to the vertical wall 4a of the side beam 4. Coach screw 23 on the vertical wall of nail 24
The above-mentioned auxiliary support post support 1 A horizontal portion 15 of the second leg piece 14 is connected to the upper wall 25a of the connecting member 25 by a bolt nut 17. This auxiliary support support 1
The second leg piece 14 of this auxiliary support post holder 1 gets in the way and makes it impossible to insert the end of the decking material 8 into the lower surface side of the upper flange portion 18a of the side beam 4. The end of the decking material 8 is notched in that part, and the gap created by this notch is filled with a screw 16 to connect the auxiliary support 9.
It is designed to be covered and hidden by a deck material presser 21 attached to the lower end.

As described above, the auxiliary column support of this invention consists of a flat plate part against which the lower end of the cylindrical auxiliary column stands upright on the upper surface of a beam such as a side beam or a front beam, and this flat plate part. a connecting piece that protrudes upward from the upper surface and is inserted into and coupled to the lower end of the auxiliary support; and a connecting piece that protrudes downward from one side of the lower surface of the flat plate and connects to the vertical wall of the beam. The first leg piece is attached and connected, and the second leg piece is formed on the other side of the lower surface of the flat plate part and is connected to the joist or connecting member connected to the beam. , this auxiliary column holder is installed so as to cover the top of the beam and is connected to the lower end of the auxiliary column. The first and second leg pieces oppose each other, and in particular, since the second leg piece is connected to a member other than the beam connected to the beam, that is, a joist or a connecting member, the load in the longitudinal direction is distributed to the member other than the beam. This allows the auxiliary support to be firmly erected on the upper surface of the beam. Therefore, even if a load is applied in the above direction to the auxiliary column, the beam itself will not twist, and the auxiliary column will shake, causing the handrail fence supported by the auxiliary column to sway, causing anxiety for the user. This completely prevents accidents such as the lower end of the auxiliary support column coming off.

Moreover, according to the auxiliary column holder of this invention, the first leg piece is connected to the beam, and the second leg piece is connected to a member other than the beam connected to this beam. There is no need to increase the width,
By forming the cross section into a vertically elongated shape, the material cost of the beam can be saved.
