Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a curtain wall type external wall structure as an external wall of a building, and provides an external wall structure that has few constituent members, is easy to construct, and is low cost. It is particularly suitable for use as a retrofit panel for existing walls.

(Prior art) For the exterior wall structure of a building, for example, a plurality of fasteners are attached to the tip of a slab of a newly constructed building frame or to the base of an exterior wall of an existing building using anchor bolts, etc., and solid wood and mullions are attached to these in a lattice pattern. The exterior wall structure was often constructed by attaching exterior panels and the like to the quadrilateral space formed by these blind timbers and mullion timbers. In this case, various methods of attaching blind timbers and mullion timbers to fasteners have been devised in the past, but none have a simple structure and are easy to construct, and there are none that are thick enough to be attached to the wall of an existing building. There was no thin outer wall structure.

(Problems that the invention aims to solve) The structure of conventional fasteners is complicated, has many parts, and is expensive. It was difficult to construct, and no consideration was given to the installation of temporary wall connecting bolts for scaffolding, which are necessary for panel type construction for renovating existing walls.

(Means for Solving the Problem) The present invention was made to solve the above-mentioned problem, and involves making the fastener into a flat plate and planting a plurality of stud bolts thereon for attaching the blank material. ,
It has a simple structure with a hole in the center for the wall connecting bolt for temporary scaffolding, and the blank material attached to the fastener is separated at the fastener part where it is needed for wall connecting for temporary scaffolding, and the wall connecting bolts are removed. Afterwards, cover with a blind cover, attach mullions to the notches formed in the designated positions of the blind timber, and hang the exterior panel board by engaging with the upward protrusions provided in the blind timber. It is intended to be installed.

(Function) By using the above-mentioned means, the cost of the fastener becomes low, and the installation work of the blind material becomes easy.
It also makes it easier to attach and detach the wall connecting bolts for temporary scaffolding.
Since the structure of each member is also simple, construction costs can be reduced. Furthermore, it is easy to ensure the flatness of the wall surface, and it can also cope with thermal expansion and contraction and interlayer displacement.

(Example) An example of the present invention will be described with reference to FIGS. 1 to 5.

In the external view of the external wall structure of the building shown in Fig. 1, a large number of fasteners 2,
A large number of blind members 4, 4... are attached to 2..., and a large number of mullion members 5, 5... are attached in a grid pattern perpendicularly to these open members 4, 4... ing. An exterior panel board 6 or a glass plate 6a is attached to a quadrilateral space formed by these lattice-like blind members 4, 4, . . . and mullions 5, 5, . . . to form an outer wall.

Details of the fastener 2 will be explained with reference to FIGS. 2 and 3. The fastener 2 is a substantially flat plate made of steel plate, and has a long hole 2 into which the anchor bolt 3 is inserted.
a, 2a are provided so that the position of the fastener 2 can be adjusted up and down when it is attached to the outer wall base 1 with the anchor bolt 3. 2b are four stud bolts planted in the fastener 2 in the direction opposite to the outer wall, and 2c in the center is a wall connecting bolt hole for temporary scaffolding, and if this is to be a screw hole, the plate thickness If the screw is thin and the screw length is insufficient, it is necessary to supplement the screw length by burring, etc., as shown in the figure. In addition, if the strength of the fastener 2 is insufficient for the wall connection, a blank hole is provided for a bolt to pass through.

The fastener 2 is attached to the outer wall base 1 as shown in Figure 1.
Anchor bolts 3, 3 provided at predetermined positions of
Insert the long holes 2a, 2a into the two nuts 2d,
2d, but its vertical position can be freely adjusted using the elongated holes 2a, 2.

The blank material 4 is attached to the mounting flange 4 as shown in FIG.
Insert the long holes in the longitudinal direction provided in a into the stud bolts 2b, 2b set in the fastener 2.
It is clamped and tightened by the two nuts 2d, 2d, but the left and right positions can be freely adjusted due to the elongated hole, and at the same time, the two nuts 2d, 2d
By adjusting the tightening method, each open material 4, 4...
It can be adjusted so that the outer surface formed by ... is flat. And the blank material 4 is fastener 2
Either it is fixed to and extended continuously in the left and right direction, or it is divided at a fastener part and extended in the left and right direction.

Both ends of the mullion timber 5 are processed to match the mutual spacing between the vertically adjacent blind timbers 4, 4.
The mounting flanges 5a are fitted into the notches formed at predetermined positions of each of the blind members 4, 4, and the mounting flanges 5a are attached to the blind members 4
is fixed to the mounting flange 4a with screws 5b.

The upper end of the exterior panel board 6 is L as shown in FIG.
It is bent into a letter shape and is suspended by engaging with an upwardly directed protrusion 4b provided on the blind member 4. At this time, the lower end and both left and right ends of the exterior panel board 6 are fitted into the upper part of the bottom blank member 4 and the side parts of the left and right mullion members 5, respectively, by means of beads with appropriate cross-sectional shapes as shown in the figure. Supported blind material 4,
It is designed to accommodate thermal expansion/contraction and interlayer displacement of the entire outer wall structure formed by mullions 5 and exterior panel boards 6. The glass plate 6a shown above the blind member 4 in FIG. 4 and on the right side of the mullion member 5 in FIG. Need to change.

The blind cover 4c has a bead 7 as shown in FIG.
is inserted and crimped to the blind material 4 to fix the panel board 6 and to have a waterproof structure.

Regarding the installation of wall joints 8 for temporary scaffolding,
As shown in FIG.
Since the wall connecting bolt holes 2c of the fastener 2 are opened outwards before the blind cover 4c is installed, the wall connecting bolt holes 2c of the wall connecting bolts 8 are installed separately at the wall connecting bolt holes 2c.
If it is a screw hole, it can be screwed directly into it, or if it is a blank hole, it can be screwed into a female screw anchor (female screw embedded in the concrete) installed in the external wall base from the outside through the hole, so it can be screwed into the wall at the required location. The scaffolding can be fixed using connecting bolts 8. Removal of the wall connecting bolts 8 begins from the upper level after the installation of the blind members 4, mullions 5, and exterior panel boards 6 is completed and before the blind cover 4c is crimped.
After the blind cover 4c is crimped, the work can be carried out without any problem if the work is continued gradually toward the lower layer.

(Effects of the invention) The building exterior wall structure according to the invention described above has the following advantages.

(1) Fasteners have an extremely simple structure, so they are low cost, and there is little protrusion from the wall base, making it possible to reduce the overall thickness of the exterior wall structure.

(2) Since the front and back, top and bottom, and left and right positions of the blind timbers and mullion timbers can be freely adjusted, the horizontal, vertical, and flatness of each member can be maintained accurately, resulting in an extremely excellent finished appearance.

(3) Since the panels are suspended from above, the flatness of the panels can be improved, and it is also possible to fully accommodate thermal expansion and contraction of the entire exterior wall structure and displacement between layers.

(4) Since all parts can be processed in advance, on-site work is extremely simplified and installation process management is easy.

(5) Waterproofing is done by beads, so there is no need for on-site sealing work.

(6) Since there is no on-site welding work, it is advantageous in terms of work and disaster prevention.

(7) There are fewer types of parts and components, making management easier.

(8) Since the wall connecting bolts for temporary scaffolding can be easily attached and detached, temporary scaffolding can be easily installed and dangers can be accurately prevented.

In summary, the present invention makes it possible to provide a low-cost exterior wall structure with good quality and performance.
