Description

[Detailed Description of the Invention] This invention relates to a support structure for supporting the outer wall of a building such as a building, and is particularly intended to provide an outer wall support structure that allows temporary scaffolding to be easily erected.

<Background of the invention> There is an external wall structure called a curtain wall as one of the external walls of a building. Curtain walls generally have a structure in which aggregate is attached to the base wall of a building in a lattice shape using anchor bolts, etc., and exterior panel boards are screwed to the aggregate attached in a lattice shape, and the entire wall surface is covered by the exterior panel board. It's summery.

When constructing a curtain wall, temporary scaffolding must be installed along the wall of the building. In order to temporarily install scaffolding, it must be connected to the wall of the building and constructed in such a way that the scaffolding will not fall outward.

<Conventional disadvantages> Conventionally, aggregates attached to the base wall of a building and scaffolding have been connected using connectors. This connector has clamps attached to both ends of the shaft, and these clamps grip the aggregate attached to the wall of the building and the pipe material constituting the scaffolding, and connect the two.

Since the connector has clamps at both ends, it is relatively expensive. However, since a large number of connectors are required, the construction cost of the scaffolding is relatively high. Furthermore, bolt tightening and bolt loosening work is required to attach and detach the clamp from the aggregate and the pipe materials that make up the scaffolding.
It also has the disadvantage of poor workability.

<Purpose of the invention> This invention makes the connecting device that connects the building and the scaffolding simple in structure, reduces the cost of the connecting device, and makes it easy to attach and detach the connecting device. The present invention aims to provide a building exterior wall support structure that can improve the workability of scaffolding construction.

<Summary of the invention> In this invention, a C-shaped groove is provided in the aggregate to be attached to the base wall of a building, and by inserting the head of the bolt that constitutes the connector into this C-shaped groove, the bolt can be tightened. It can be connected to a building. Therefore, a bolt can be used as the connector, and the connector can be made inexpensive. It is also expected to improve work efficiency since it will be easier to attach and detach the device to the building.

<Example of the invention> An example of the invention is shown in FIGS. 1 and 2. Figure 1 is a cross-sectional view of the outer wall structure of a building based on this invention, viewed from the side, and Figure 2 is a
It is a sectional view on the A line. 1 in the figure shows the base wall surface of the building. Fasteners 3 are attached to this base wall surface 1 with anchor bolts 2. The fasteners 3 are attached to the entire base wall surface 1 of the building in a lattice pattern with predetermined intervals maintained in the vertical and horizontal directions. The figure shows only one fasuna part. A screw hole is provided in the fastener 3, a bolt 4 is screwed into the screw hole, and the mullion 5 is attached along the wall surface 1 by the bolt 4. The mullions 5 are extended vertically, and rows of a plurality of mullions 5 are formed on the wall surface 1.

In this invention, a C-shaped groove 5a as shown in FIG. 2 is formed in an aggregate such as a mullion 5 attached to the base wall surface 1 of a building.

A scaffold (not specifically shown) can be fixed to a building by inserting the head of a scaffold wall connecting bolt 6 into the groove 5a. Therefore mullions 5
Scaffolding can be sequentially assembled and assembled upward when the scaffolding is sequentially extended upward and installed. At this time, by providing a gap larger than the diameter of the head of the scaffold connecting bolt 6 at the joint portion of the mullion 5, the head of the scaffold connecting bolt 6 can be inserted into the groove 5a through this gap.
Therefore, by sequentially inserting the heads of the scaffold connecting bolts 6 into the grooves 5a of the mullions 5 and supporting the scaffold by the scaffold connecting bolts 6, it is possible to prevent the scaffold from falling outward.

The mullion 5 has a notch 5b as shown in FIG. 1, and the blind member 7 is engaged with the notch 5b. Seamless wood 7
is passed between adjacent rows of mullions 5, and its ends are inserted into notches 5b formed in the mullions 5. The blind material 7 has ridges 7a on the top and bottom for retaining the beats,
7b, and the bead 8 is fitted into and held by the protrusions 7a and 7b. It has an auxiliary protrusion 7c on the back side facing the beat holding protrusion 7b, and this protrusion 7c
A groove 9 is formed by the and protrusion 7b, and the cut portion of the notch 5b formed in the mullion 5 is inserted into this groove 9.
A blind timber 7 is constructed between the mullion timbers 5. As a precaution, the mullions 5 are sewn together with the mullions 7 using screws 11 to prevent the mullions 7 from coming out of engagement with the mullions 5.

In a state where the open timber 7 is passed between the mullion timbers 5, the exterior panel board 12 is attached to the protrusion portion 7 of the mullion timber 7.
d (Fig. 1) and hang it. For this purpose, a folded part 12a (Fig. 1) is attached to the upper side of the exterior panel board 12.
is formed, and the folded portion 12a is hooked on the protrusion 7d to hang the exterior panel board 12. Exterior panel board 1
2 has a length such that its lower end is in contact with the upper bead 8 of the lower blind material 7 when it is suspended.

After hanging the exterior panel board 12, open cover material 1
3 (FIG. 1) is fitted into the blank material 7. Reference numeral 13a denotes an engagement protrusion formed on the blind cover material 13.
A bead 14 is attached to the seamless cover material 13,
The exterior panel board 12 is brought into pressure contact with the bead 8 attached to the blind material 7 via this bead 14.

When the blind cover material 13 is installed, the exterior panel board 1
2 is firmly supported by the blind member 7. When the construction progresses to this point, the scaffolding is removed from above and the crimp material 15 (Fig. 2) is attached to the mullion 5. That is, in order to attach this pressure bonding material 15, the scaffolding connecting bolt 6 is removed from the groove 5a of the mullion 5. This removal can be done by sliding the bolt 6 up or down and taking it out from the groove 5a at the joint of the mullion 5. After removing the scaffolding connecting bolts 6, attach the crimp material 15 to the screws 16.
Install by. The crimp material 15 is selected to be approximately equal to the arrangement interval of the blind members 7, and is attached each time the work of removing the scaffold connecting bolts 6 is completed. The pressure welding material 15 has a bead 17, and this bead 17
(Fig. 2) is the side edge of the exterior panel board 12
Press the bead 18 (Fig. 2) attached to the
A mullion cover material 19 is fitted onto the pressure bonding material 15. As shown in FIG. 1, a cutout 19 is formed in the mullion cover material 19 at a portion that is in contact with the open cover 13, and the engagement of the cutout 19 with the open cover material 13 causes the mullion cover 19 to move downward. I try not to let it fall off.

For the mullions 5, blind members 7, exterior panel plates 12, blind cover members 13, and mullion cover members 19 described above, for example, extruded aluminum materials can be used.

<Effects of the invention> As explained above, in this invention, a C-shaped groove 5a is formed in the aggregate attached to the base wall surface 1 of the building, or in the mullion 5 in the embodiment, and the groove 5a is used for connecting scaffolding. Since the scaffold connecting bolt 6 is connected to the building by inserting the head of the bolt 6, it is easy to attach and detach the scaffold connecting bolt 6 to the building. This provides the advantage of improving the workability of scaffolding construction work. Furthermore, since a simple bolt 6 can be used as a scaffold connector, the cost can be lowered compared to conventional connectors, and the construction cost of the scaffold can be reduced.

Although the example in which the C-shaped grooves 5a are formed in the mullion material 5 has been described above, they may be formed in the blind material 7.
