Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an ALC (Autoclave
d Lightweight Concrete) It relates to the laying structure of ALC floorboards using panels as building floorboards.

[0002]

2. Description of the Related Art An ALC floorboard of this type is a building flooring material in which lightweight cellular concrete having a myriad of cells inside is molded into a fixed panel shape by high-temperature and high-pressure steam curing, and reinforcing bars are buried inside the panel. Therefore, it is known that a first floor or a second floor excellent in sound insulation, heat insulation, creaking resistance and the like can be easily constructed. On the other hand, due to the large consumption of timber resources, there is a shortage of building materials such as bargains, joists and instrument panels. In addition, the demand for prefabricated houses is increasing, and the shortage of craftsmen is being tightened. Therefore, promotion of floor construction using ALC floor boards is expected.

FIG. 7 shows a conventional laying structure using such an ALC floor plate. Generally, the ALC floor panel 10 has a rectangular shape in a plan view, and upper corners of both side surfaces are cut out to form a step 22.
It has been. The ALC floor plate 10 is placed on the upper surfaces of the cross beams 5 and 8 after the upper building and is spread. At this time, a cutting operation is performed in which a corner portion of the ALC floor panel 10 that interferes with the through pillar 2 is cut out with a motor saw or the like to form a cutout portion 28.
Subsequently, the cotter holes 11 are formed in the ALC floorboard 10 after the spread.
Is drilled. Next, the mortar 25A is filled between the step portions 22 and 22 of the adjacent ALC floor plate 10 or in the gap between the notch 28 of the ALC floor plate 10 and the column 2. In addition, a joint reinforcing bar 23 inserted into the threaded markan 24 is embedded between the step portions 22. The threaded markan 24 is arranged in the cotter hole 11 or the like.

[0004] Alternatively, in another laying structure shown in FIG. 8, since the ALC floor plate 10 is placed on the upper surface of the cross beam 45 or the like laid laterally on the through pillar 42 after the upper building, the ALC floor plate which interferes with the tube column 31 is installed. A cutting operation is performed in which the corners 10 are cut out with an electric saw or the like to form the cutouts 28, or conversely, the studs 32 are cut out to form the cutouts 33.

[0005]

By the way, for example, when the ridge is raised, the studs 32 and the like have not been erected yet.
Notches 28 and 32 cannot be formed in LC floorboard 10 and stud 32. Therefore, the ALC floor panel 10 could not be spread on the cross beams 5, 8, and 45. Therefore, without stopping, temporarily place a control panel etc. between the cross beams to secure the scaffold, and with the carpenter riding on a stepladder placed on it,
We take the girder material that has been transported by wreckers and work on knocking it into pillars. Such an upper building work is a work on a very unstable scaffold, and moreover, a large number of man-hours must be performed in a short time, leading to frequent occurrence of accidents.

On the other hand, the ALC floorboard 10 to be performed after building
In the laying work, the cutting work of providing the cutout 28 on the ALC floor plate 10 side and the cutout 33 on the column side using a small electric saw while taking dimensions, or the drilling work of the cotter hole 11 must be performed one by one. And the work was complicated.

On the other hand, AL in each conventional structure
Since the C floor plate is simply placed on the cross beam, if there is a roll such as an earthquake, the ALC floor plate is easily displaced with respect to the column and the cross beam, and is inferior in earthquake resistance.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an ALC floorboard laying structure which is excellent in workability when laying a floorboard and is excellent in earthquake resistance.

[0009]

Means for Solving the Problems To achieve the above object, an ALC floor laying structure according to the present invention has a structure in which the ALC floor slab is stretched between horizontal beams arranged in parallel with each other. Inwardly projecting portions are respectively protruded from the opposing surface at a position lower than the upper surface of the cross beam, and A
It is configured to support both ends of the LC floor panel.

[0010] In addition, each of the protrusions in the above-described configuration is provided so as to protrude from an opposing surface of each cross beam at a vertical position where the upper surface of the ALC floor plate is substantially flush with the upper surface of the cross beam in a state of being bridged between the cross beams. It is a thing.

Further, in each of the above structures, AL
The space between the C floor plate and the cross beam is filled with a silicone resin-based sealing material.

In each of the above configurations, A
The fine holes on the upper surface of the LC floor plate are exposed, and the decorative floor plate is fixed to the upper surface via an adhesive. However, the decorative floor board includes not only a wood grain pattern printed or pasted on the surface but also a control panel board and the like.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of an ALC floorboard laying structure according to an embodiment of the present invention as viewed from the direction of arrow B in FIG. 2, FIG. 2 is a plan view showing the ALC floorboard laying structure,
FIG. 3 is a sectional view taken along line AA in FIG. However, FIG.
The same components as those of the conventional laying structure shown in FIG. 8 are denoted by the same reference numerals, and detailed description thereof may be omitted.

In the ALC floorboard laying structure shown in FIGS. 1 to 3, reference numerals 17 and 19 denote concrete foundations erected from the ground, respectively, and reference numeral 15 denotes a laterally mounted foundation 17 fixed by anchor bolts 18. Base, 16 is foundation 1

6 is a horizontal beam on the second floor spanned between pillars 3 and 4;
Reference numeral 8 denotes a horizontal beam on the second floor bridged between the column 2 and the column 4, and reference numeral 9 denotes a vertical column on the cross beam 5. Subsequently, reference numeral 12 indicates the horizontal beams 5, 7, 8
Wing plate bolts for holding and fixing the cross beams 6, 8
Reference numeral 13 denotes an inward portion made of a square bar, 14 denotes an inward portion made of a square bar, and 20 denotes an ALC floorboard 10, 1 spread on the first floor.
Reference numeral 0 denotes a control panel attached on the upper panel, and reference numeral 21 denotes a decorative floor attached on the ALC floor panels 10, 10, ... spread on the second floor.

In this ALC floorboard laying structure, in particular, the inwardly protruding portion 1 is located at a position opposite to the upper surfaces 5a and 6a of the cross beams 5 and 6 which are arranged in parallel with each other.
3, 14 are protruded respectively. And horizontal beam 5,
A large number of ALC floor boards 10, 10,... Are laid over the inside of the inside 6 and on the upper surfaces of the inside-out portions 13 and 14, and are laid. That is, both ends of the ALC floor plate 10 are supported on the upper surfaces of the inner protrusions 13 and 14, respectively. In this case, the inwardly extending portions 13 and 14 are arranged vertically so that the upper surface 10a of the ALC floor plate 10 bridged between the cross beams 5 and 6 is substantially flush with the upper surfaces 5a and 6a of the cross beams 5 and 6. Is provided. Similarly, the ALC floorboard 10 on the first floor is also used as a base 15,1.
6 and flush with each other.

Also, as shown in FIG.
Relatively wide gaps are formed between the floorboards 10 with the step portions 22 facing each other. In this gap portion, first, holes of 9 mm diameter are respectively formed in the inner surfaces of the cross beams 5 and 6, and the holes 35 and 3 of 10 mm diameter are formed in these holes.
5 are each knocked. Then, each deposit 35,
At the tip of the joint 35, both ends of the joint reinforcing bar 23 are integrally tied together with binding wires, so that the joint reinforcing bar 23
A hollow arrangement is provided between 2 and 22. In this state, the gap is filled with mortar 25A as in the conventional case.

In this case, in particular, a silicone seal material 25 is provided in a small gap between the ALC floor plate 10 and the cross beams 5, 6, 7, and 8.
(See FIG. 5 below). Since the silicone seal material 25 is filled in the gap between the ALC floor plate and the cross beam as described above, further sound insulation and heat insulation can be obtained, and the silicone seal material 25 has elasticity, high durability, The ALC floorboard does not degrade with time because of its excellent adhesiveness to ALC. By the way, when the mortar 25A is filled in the above gap, the mortar 25A
A hardly adheres to wood, and when it dries, large cracks may occur, or it may fall off to create new gaps. Therefore, there is a problem that the sound insulation and the heat insulation gradually decrease over time.

According to the ALC floorboard laying structure having the above-described structure, as shown in FIG. 5, the inner protrusions 13 and 14 are provided with the screws 3 on the opposing surfaces lower than the upper surfaces of the cross beams 5 and 6, respectively.
0, and both ends of the ALC floor plate 10
Since the ALC floor plate 10 is supported by the upper surfaces of the ALC floor plates 3 and 14, respectively, the ALC floor plate 10 is dropped and fitted in the frame surrounded by the cross beams 5, 7, 6, and 8, and an integrated structure having high rigidity is obtained. Therefore, the earthquake resistance is increased. As a result, the cotter hole (reference numeral 11 in FIGS. 7 and 8) conventionally drilled at the site after paving to prevent the strength from increasing and the position is shifted is not required to be provided here. it can.

In addition, since the ALC floor plate 10 can be positioned and guided by the inner surfaces of the cross beams 5, 7, 6, and 8 above the inwardly extending portions 13 and 14, the spreading work becomes very easy. In addition, as long as the vertical positions of the inner protrusions 13 and 14 are strictly determined, the work of mounting the lateral protrusions 5 and 6 on the side surfaces can be performed relatively easily. For this reason, it is also possible to mount the inside-out portions 13 and 14 in another work place in advance. In addition, since it is not necessary to provide the notches 28, 33 for the pillars 1, 2, 3, 4, 9, or the ALC floor panel 10 as in the related art, the floor panel laying operation can be performed quickly and easily. And the occurrence of accidents can be reduced.

Also, since the upper surface 10a of the ALC floor plate 10 is flush with the upper surfaces 5a, 6a (or 15a, 16a) of the cross beams 5, 6 (or the bases 15, 16), the floor is widely used as the same plane. It can be used and the degree of freedom of work increases. For example, the decorative floorboard 21 can be spread not only on the ALC floorboard 10 but also over a wide range extending across the cross beams 5 and 6. Further, by fixing the ends of the decorative floorboard 21 with screws 29 or the like, a stronger integrated structure including the columns, the cross beams 5, 6, the ALC floorboard 10, and the decorative floorboard 21 can be obtained. The upper surface of the ALC floor plate does not necessarily have to be flush with the upper surface of the cross beam.
Cross beams 5, 6 like ALC floor panel 10 shown by two-dot chain lines in the middle
Position higher or lower than the upper surface (not shown)
However, it goes without saying that workability and earthquake resistance are excellent.

The upper surface of the ALC floor plate 10 on the second floor is shown in FIG.
As shown in (1), for example, compressed air from an air compressor is blown to remove fine concrete powder on the surface in advance, so that countless fine holes 27 are exposed. In this state, the decorative floorboard 21 for flooring is fixed to the upper surface of the ALC floorboard 10 via an adhesive 26 (for example, a slightly softer woodworking bond). When fixed in this manner, even if a considerable force is applied to peel as indicated by arrow R, the effect of the adhesive 26 that has entered the fine holes 27 exhibits an anchor effect, and the decorative floorboard 21 is not easily peeled. . Therefore, when a stronger force is applied, the portion indicated by the two-dot chain line L is firmly adhered to such an extent that it can be peeled off. By devising in this way,
It could be stuck directly on the ALC floorboard 10.

Similarly, when the fine holes 27, 27,... Are also exposed on the upper surface of the ALC floor plate 10 on the first floor, it goes without saying that the control panel plate 20 can be firmly adhered with an adhesive. Although the fine holes 27 were not exposed even when the surface of the ALC floor plate 10 was swept with a broom or the like, they could be reliably exposed by using compressed air. Incidentally, when the decorative floorboard 21 was fixed with the adhesive 26 without blowing off the fine concrete powder, the adhesive strength was low due to the interposition of the concrete powder, and it was easy to peel off. Therefore, direct pasting to the ALC floorboard 10 has not been performed.

In the above-described embodiment, the inward projections 13 and 14, which are separate components, are fixed to the opposing surfaces of the cross beams. However, the present invention is not limited to this embodiment. It may be used as a cross beam, and the upper corner portion of each opposing surface may be cut out to form the inward projection and the cross beam integrally.

[0024]

As described above, the ALC according to the present invention
According to the floor plate laying structure, since both ends of the ALC floor plate are supported on the upper surfaces of the inwardly projecting portions respectively protruding from the opposing surfaces of the cross beams, the ALC floor plate is fitted into the opposing surfaces of the cross beams. In this state, it has a high-strength integrated structure and has high earthquake resistance. Further, since it is not necessary to provide a notch or a cotter hole for each pillar or ALC floor plate as in the related art, it is possible to quickly and easily perform the laying work. Conventionally, for example, it was impossible to spread ALC floorboards at the time of building, but in the structure of the present invention, ALC floorboards can be spread even before building as long as there are only parallel beams. Therefore, the upper building work can be performed using the spread ALC floorboards as a stable base. Therefore, the work at the time of building up is greatly facilitated, and the risk of an accident is reduced as much as possible. By these, AL
This promotes floor construction using C floorboards.

Further, since the upper surface of the bridged ALC floor plate is substantially flush with the upper surface of the cross beam, the upper surfaces of the ALC floor plate and the cross beam can be widely used as the same plane. Also,
For example, a decorative floor plate placed on the upper surface of the ALC floor plate can also extend on the upper surface of the cross beam.

Furthermore, since the gap between the ALC floorboard and the cross beam is filled with a silicone resin-based sealing material, the sound insulation and heat insulation properties of the ALC floorboard can be further improved over a long period of time.

Since the decorative floor plate is fixed to the upper surface of the ALC floor plate through which the fine holes are exposed via an adhesive, the decorative floor plate can be stuck to the upper surface of the ALC floor plate with good adhesiveness.
