Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to a structure for attaching a lightweight aerated concrete plate to a corral in a building.

b. Prior Art A conventional extension of a building, such as a balcony, has a structure as shown in FIG.

That is, the veranda is attached to the main frame of an architectural structure (not shown), and includes a horizontal protruding member 52 constituting the floor 51, and a vertical protruding member 52 disposed on the edge of the protruding member 52 in a direction substantially perpendicular thereto. wall 53
It is made up of. The vertical wall 53 is formed of a lightweight aerated concrete board (hereinafter abbreviated as ALC board) 54, and the ALC board 54 is attached to a steel beam 55 connected to the main frame via various attachment members.

Thus, the ALC plate 54 is attached to the mulloid angle 58 by passing through the tips of hook bolts 56 inserted at the upper and lower ends and on both left and right sides and hooking them to the angle 57. connects the steel beam 55 through the piece angle 59
is fixed to.

c Problems to be solved by the invention However, in the conventional ALC board mounting structure described above, hook bolts 56 and mullions are attached to the rising surface of the ALC board 54 on the balcony vertical wall 53 facing the building side (right side in the figure). Since the angle 58 and the like are exposed, an uneven surface (unevenness) will occur. Even if waterproofing was performed in this state, cracks would occur in the waterproof membrane between the metal fittings and the ALC board 54, and as a result, there was a risk that the appearance would deteriorate. Therefore, from the viewpoint of aesthetics and waterproofing, it was necessary to apply lath base mortar 60 not only to the parts of the metal fittings, but also to the entire board surface to avoid unevenness.

In addition, in the conventional mounting structure, the receiving angle 57 is exposed at the lower end of the ALC board 54, so even if the surface of the ALC board 54 is painted,
The waterproof membrane attached to the area between the tip of the angle 57 and the bottom surface of the ALC board 54 may crack due to the gap between the two due to vibrations, etc., and water may enter from there. has become a weak point in terms of waterproofing. For this reason, angle 5 is usually
It was necessary to provide a drain plate 61 at the bottom of the ALC plate 7 to cover it, and to seal between the drain plate 61 and the ALC plate 54 to ensure waterproofing and eliminate the above-mentioned weaknesses in waterproofing.

On the other hand, the ALC board 54 has water absorption properties, and its surface must be finished with painting, etc. Therefore, in the conventional mounting structure in which a drain plate 61 is provided, the drain plate 61 must be used during waterproof painting work. This has the disadvantage that it requires additional installation work, which increases the number of waterproofing operations.

In addition, there are many mounting members for mounting the ALC board 54, and each of these mounting members must be assembled on site, making the assembly work complicated.

As described above, the conventional ALC plate mounting structure has poor construction efficiency, increases construction costs, prolongs the construction period, and is extremely disadvantageous economically.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide an ALC plate mounting structure for a take-out portion that can eliminate the above-mentioned drawbacks.

d Means for solving the problem In order to solve the problem of the above-mentioned conventional technology,
In the present invention, a reinforcing member extending vertically is buried inside a lightweight aerated concrete plate that is vertically arranged to constitute a carry-out section.
A cut-out portion is formed in the lightweight aerated concrete plate to partially expose the reinforcing member, and the reinforcing member at the exposed portion and a steel beam supporting an adjacent slab are fixed to each other via a connecting member. There is.

e Examples The present invention will be described in detail below based on illustrated examples.

1 to 3 show a balcony to which an embodiment of the ALC board mounting structure according to the present invention is applied. In the figure, 1 is a horizontal slab, that is, a protruding member, attached to the main frame (not shown) of the building structure, and the floor 2 on the balcony is formed by applying protective mortar 3 on the upper surface of this protruding member 1. It is formed by surface finishing. A vertical wall 4 is disposed at the edge of the protruding member 1 in a direction substantially perpendicular thereto, and the vertical wall 4 and the floor 2 constitute a balcony.
An I-shaped steel beam 5 with a wide flange, which is connected to the main frame and supports the protrusion member 1, is fixed on the lower surface of the tip of the protrusion member 1 along the width direction of the balcony. An ALC board, which will be described later, can be attached to the beam 5.

On the other hand, the vertical wall 4 is formed by joining a plurality of ALC plates 6 to each other, as shown in FIG. A reinforcing buried body 7 is buried in each ALC board 6, and the buried body 7 has a lattice shape in which a plurality of reinforcing bars 8 are arranged vertically and horizontally. Also
Embedded steel materials 9 are embedded in both sides of the ALC board 6 for reinforcing the support and are formed in an L-shaped cross section extending in the vertical direction. The outer surface of one attachment piece 9a is arranged to face the steel beam 5.

In addition, a plurality of cut portions 10 are provided on the building side surface of the ALC board 6 at positions corresponding to the piece angles described later, and the embedded steel material 9 in the ALC board 6 is inserted through these cut portions 10 as shown in FIG. And as shown in FIG. 3, it is partially exposed. However, the embedded steel material 9 at these exposed locations
and the steel beam 5 are fixed to each other via an L-shaped piece angle 11 which is a connecting member, and the ALC plate 6
is attached to the main frame of the building via these attachment members.

Note that in this embodiment, the "extended portion" does not refer to the entire veranda, but the part of the vertical wall 4 above the piece angle 11 arranged above and the part of the vertical wall 4 below the piece angle 11 arranged below. (See Figure 1) In other words, when constructing a vertical wall, the ALC board is generally erected in the longitudinal direction and its upper and lower ends are fixed to the steel beams, but when only the middle part of the ALC board is fixed, as in the case of a vertical wall on a balcony. , the part above or below the fixed part becomes the "holding out part".
In addition, in the parapet section (rooftop section), ALC
Since only the lower end of the plate is fixed, the part above the lower end becomes the "hold-out part".

Furthermore, as shown in FIG. 1, a bending-shaped strut 12 is fixed to the upper end surface of the ALC plate 6, and by attaching a cap 13 to this strut 12, the upper end of the vertical wall 4 is covered. ing. Further, a sealing material 15 is sealed between the inner and outer surfaces of the vertical wall 4 and the inner wall surface of the cap 13 with backing material 14, and the filled sealing material 15 closes the gap. It's broken. A ceiling (not shown) is disposed below the steel beam 5 so as to face the protruding member 1, and the steel beam 5 and the like are covered by the ceiling.

Next, the procedure for attaching the ALC board 6 having the above configuration will be described. First, the protruding member 1 and the steel beam 5 are attached to the main frame of the building structure. Next, one attachment piece 11a of the piece angle 11 is joined to the upper and lower flange portions 5a, 5b of the steel beam 5 by welding, respectively.

On the other hand, by carving a predetermined location on each ALC board 6,
A cut portion 10 is formed to partially expose the embedded steel material 9. Then, the ALC plate 6 is arranged to be substantially orthogonal to the edge of the protrusion member 1, and the corresponding cut portion 10 and piece angle 11
The exposed embedded steel material 9 is brought into contact with the piece angle 11. In this state, the embedded steel material 9 and the other mounting piece 11b of the piece angle 11
and are joined to each other by welding, and the ALC plate 6 is attached to the steel beam 5 (see Fig. 2). However, one
The ALC plate 6 is fixed to the steel beam 5 at four locations via piece angles 11.

By repeating these steps and joining a required number of ALC boards 6 along the width direction of the veranda as shown in FIG. 3, the vertical wall 4 is formed. After that, a cap 13 is attached to the upper end of the vertical wall 4 to cover it, and a protective mortar 3 is applied to the upper surface of the protruding member 1 to finish the surface, thereby forming a floor 2 and constructing a veranda. (See Figure 1).

In addition, specifically showing the dimensions of each member used in the above example, the ALC board 6 has a height of 1600 mm x width of 600 mm x
Thickness: 100 mm, embedded steel material 9 has cross-sectional dimensions of 60 x 60 x
It is 4mm. In addition, the height of the ALC board 6 that constitutes the vertical wall 4 of the veranda is the height up to the top of the Kasagi 13.
Considering 1100mm, it is extended about 1050mm from the two floors.

Although one embodiment of the present invention has been described above, the present invention is not limited to the embodiment described above, and various modifications and changes can be made based on the technical idea of the present invention.

For example, in the above-mentioned embodiments, the embedded steel material 9 for reinforcing the protrusion part was formed with an L-shaped cross section, but depending on the thickness and strength of the ALC board 6 used, the steel material 9 may have a T-shaped cross section. , a U-shaped cross section or other shapes may be used. Further, in the above-described embodiments, the ALC board mounting structure of the present invention is applied to the vertical wall 4 of a balcony, but it may also be applied to a projecting part of a building such as a parapet.

f. Effects of the invention As described above, the ALC plate mounting structure of the carry-out part according to the present invention embeds a reinforcing member extending vertically inside the ALC plate that constitutes the carry-out part by vertically arranging it. , the reinforcing member is partially exposed through the cut-out part formed in the ALC board, and is fixed to the connecting member and the steel beam, and is not attached to the steel beam at any point other than the location where it is attached to the steel beam (a location that is not visible from the outside). Since there are no uneven surfaces, there is no need to apply lath base mortar and waterproofing can be done directly, which makes waterproofing easier. In addition, the invention
With the ALC board mounting structure, metal fittings such as receiving angles are not exposed as in the past, and there is no weak point in terms of waterproofing between these metal fittings and the ALC board. There is no need to install a board, and only waterproof coating is required. Therefore, if the ALC board mounting structure of the present invention is applied to a balcony or other extended area, workability can be improved and construction costs can be reduced.

Furthermore, the ALC board mounting structure of the present invention requires fewer mounting parts to be assembled on site, and some of the complicated assembly work can be omitted, making it possible to significantly shorten the construction period and being extremely economically advantageous. .
