2. Description of the Related Art Conventionally, as a panel construction method for a quasi-fireproof building, a bone frame composed of an upper frame 1, a roll stopper 2, a lower frame 3 and a vertical frame 4 made of a wooden shaft as shown in FIG. The 2x4 construction method in which the panel covering the face material 5 is joined as a wall material and a floor material to form structural strength, and the panel in which the face material is combined with the steel frame is joined as a wall material and a floor material to obtain the structural strength. There is a built-in steel frame type panel construction method, and a concrete panel construction method in which structural strength is formed by joining plate-shaped rebar-reinforced concrete panels as wall and floor materials.

Each panel used as a wall material or floor material in the above-mentioned structure has its own ability as a structural material, and the above-mentioned frame, steel frame, and reinforcing bar anchored in concrete have a predetermined structural strength. It is expressed.

[0004]

Since the above-mentioned panel has to be added with strength as a structural material, the process of giving strength is complicated and the cost is high unlike curtain wall. A refractory coating must be applied, which further increases the cost. The present invention has been made in view of the above problems of the conventional technique, and an object thereof is a lightweight, inexpensive extrusion-molded cement used as a non-structural material for an interior / exterior material base. It is intended to provide an inexpensive extruded cement board with a built-in frame for a panel construction method, which is excellent in fire resistance as a structural material by adding structural strength to the board.

[0005]

In order to achieve the above object, an extrusion-molded cement board with a built-in frame for a panel construction method according to the present invention is used as a wall or floor panel and is extruded with hollow holes at both ends in the extrusion-molded cement board. It is constructed by incorporating a structural steel frame surrounding frame such as a square pipe into a groove for cutting on both end faces orthogonal to the direction.

[0006] A structural steel frame such as a square pipe is incorporated in hollow holes at both ends of an extruded cement board. A structural steel frame such as a square pipe is incorporated into hollow holes at both ends of an extrusion-molded cement plate, and both ends of an intermediate hollow hole are filled with mortar.

[0007] Structural steel frames such as square pipes are incorporated in hollow holes at both ends of an extruded cement board, and flat bars for horizontal stress transmission are attached to both end faces orthogonal to the extruding direction. A structural steel frame such as a square pipe is incorporated in hollow holes at both ends of an extrusion-molded cement board, and horizontal stress transmitting angles are covered on both end faces orthogonal to the extrusion direction.

The extrusion-molded cement plate is made by inserting reinforcing bars into the hollow holes at both ends and filling the mortar with the iron plates. In this method, reinforcing bars are inserted into the hollow holes at both ends of the extruded cement plate, the mortar is filled with iron plates, and both ends of the hollow hole in the middle are filled with mortar.

[0009] Reinforcing bars are inserted into hollow holes at both ends of the extruded cement plate, the mortar is filled with iron plates, and flat bars for horizontal stress transmission are attached to both end faces orthogonal to the extruding direction. It is a thing. The extrusion-molded cement plate is formed by inserting reinforcing bars into the hollow holes at both ends and covering the mortar with iron plates, and covering both end surfaces orthogonal to the extrusion direction with angles for horizontal stress transmission.

In the above wall panel, the surface is vertically and horizontally 2
It is good to apply a direction joint pattern. As a floor panel to be attached to a suspended ceiling, a hollow rib is formed in the extrusion direction on the lower surface of an extrusion-molded cement board, and a hanging bolt mounting slit is formed on the lower side of the hollow rib.

The first described method of manufacturing an extrusion-molded cement board with a built-in frame for a panel construction method as a floor panel without a wall or a suspended ceiling installation according to the present invention is to perform curing after curing by hollow molding, and wait in the extrusion direction. Grooves are cut on both end faces of the orthogonal plate,
After that, the structural steel frame formed in a U-shape is attached to the hollow holes at both ends and one groove, and the structural steel frame corresponding to the frame side remaining in the other groove is attached. The two are welded together to complete the surrounding frame.

The first described method of manufacturing an extruded cement board with a built-in frame for a panel construction method as a floor panel to be mounted on a suspended ceiling according to the present invention is to attach a hollow rib having a slit on the lower side to the lower surface of the board. After the hollow molding extrusion of, wait for curing and cure, cut the groove on both end faces of the plate orthogonal to the extrusion direction,
After that, the structural steel frame formed in a U-shape is attached to the hollow holes at both ends and one groove, and the structural steel frame corresponding to the frame side remaining in the other groove is attached. The two are welded together to complete the surrounding frame.

[0013]

The extruded cement board having no structural strength is reinforced remarkably by incorporating at least the vertical axis set, and horizontal stress transmission is difficult due to the lack of a cross section due to the presence of the hollow hole, but it can be made into a structural material. In addition to this, in the case of treating the horizontal framing as well, the horizontal stress transmission can be perfect. That is, the extruded cement board which is a non-structural material has the strength as a panel in the panel construction method due to the synthetic effect integrated with the structural steel frame surrounding frame and the like. The axial force such as vertical load is borne by the steel frame, and the in-plane shear force such as buckling of the steel frame due to the axial force and interlayer displacement is borne by the extruded cement plate and the horizontal steel frame.

Thus, there is provided a panel which is hollow, inexpensive, lightweight, highly resistant to fire, and excellent in sound insulation, and which is transformed into one having structural strength while retaining the characteristics of the extruded cement board. Moreover, the manufacturing process of the extrusion-molded cement board is simply an extremely simple post-processing, and the manufacturing cost is low.

[0015]

EXAMPLE An example will be described with reference to the drawings. In FIGS. 1 to 6, hollow extruded cement boards 6 which are conventionally hollow and have no structural strength are used as curtain walls. A rectangular structural steel frame surrounding frame 9 such as a square pipe is integrally incorporated into the holes 7 and 7 and grooves 8 and 8 which are cut on both end faces orthogonal to the extrusion direction by means of screws 10 ,.

However, the plate 6 having no structural strength up to that point has a strength as a panel in the panel structure due to the synthetic effect. Thus, the reinforced plate 6 can be used for a wall or floor as a panel in a panel construction method as shown in FIG. 1 to form a panel structure. At this time, when it is used as the outer wall panel 6a, it is preferable to apply a vertical and horizontal two-way joint pattern 11 to the surface as a makeup to form a main stone or a tile pattern. In the case of this outer wall panel 6a, as shown in FIG. 2, it is preferable to form the uneven shape 19 on both end faces for the purpose of interlocking between adjacent panels.

When used as a floor panel 6b for mounting a suspended ceiling, as shown in FIG. 3, a hollow rib 12 having a slit 14 for mounting a hanging bolt 13 is attached to the lower side of the plate 6 in the extrusion direction. It shall be. The large-diameter portion of the anti-vibration rubber 15, the washer 16, and the nut 17 attached to the upper end of the hanging bolt 13 is inserted from the opening of the plate end surface, or partially cut into the slit 14 as shown in FIG. It may be provided by inserting it from here and suspending it. However, it is simpler than the conventional means for suspending the suspension bolt by embedding the cap nut, and it is rational to effectively utilize the rib that contributes to the stiffening.

A field edge receiver 21 is supported on the lower end of the suspension bolt 13 via a hanging metal object 20, and a ceiling finishing material 23 is supported via a field edge 22. Figure 4 shows the manufacturing method for floor panels and wall panels that do not require suspended ceiling installation.
As shown in FIG. 5, grooves 8 are cut on both end faces of the plate 6 that has been cured by curing in a direction perpendicular to the extrusion direction, and thereafter, a part of the surrounding frame 9 formed into a pre-shaped U shape is formed. Structural steel frame 9a
Is attached to the hollow holes 7 and 7 on both ends and one groove 8 and the structural steel frame 9b forming the remaining part of the frame 9 is attached to the other groove 8 and welded and joined to complete the enclosure. In the case of a floor panel that needs to be attached to a suspended ceiling, the manufacturing method is to form a hollow rib 12 having a slit 14 at the lower side on the lower surface of the plate by a mold during extrusion molding, and after curing and curing,
The cutting of the grooves 8 and 8 and the mounting and welding of the structural steel frames 9a and 9b are performed.

FIG. 5 shows a panel structure including the upper wall, the floor panel 6a and the floor panel 6b. That is, basic 2
4, 25 support the wall panel 6a and the plate 6 as the first-floor panel, and further, through the beam 32, the upper and lower-floor wall panels 6a, 6a and the suspended-ceiling-mounted second-floor floor panel 6b. Argued. In the figure, 27 is a border panel that covers the beam 32, and 28 is an interposed heat insulating material.

On the inside of the wall panel 6a, it is preferable to apply an internal makeup 29, as shown in detail in FIG. The non-structural extruded cement board 6 does not have to be structured by the same material as the above structural steel frame surrounding frame 9. That is,
It was confirmed that the horizontal axis set was omitted or the minor allowance was sufficient compared to the vertical axis set.

Each example will be introduced below. FIG. 7 shows the holes 7,
7 is a structural steel frame 30, 30 such as a square pipe.
1, 31 is an example of assembly by injection, and a bolt 33 for mounting the counter beam 32 is installed at the open end of the steel frame 30 in an upright manner.
4 is covered. The horizontal force transmission depends on the cement board 6.

FIG. 8 shows a case where the horizontal force transmission is unsatisfactory in FIG. 7, and the mortar 3 is provided at both ends of the hollow holes 7 ',.
5, are filled to eliminate cross-section defects and reinforce. FIG. 9 shows that the same purpose of reinforcement is achieved by covering the horizontal stress transmitting flat bars 36, 36 with tapping screws 37, ... On both end surfaces orthogonal to the extrusion direction.

Further, FIG. 10 shows that the angles 38, 38 are covered with tapping screws 37, .... FIG. 11 shows that, instead of the structural steel frame 30 of FIG. 7, the reinforcing bars 39, 39 are inserted into the holes 7, 7 and then the mortars 40, 4 are inserted.
The zero filling is performed under the lid of the iron plates 41, 41.

Hereinafter, FIG. 12 corresponds to a modification of the steel frame 30 of FIG. 8, FIG. 13 is a modification of FIG. 9, and FIG. 14 is a modification of FIG.
Each change corresponds to a change of 0. However, in FIGS. 13 and 14, the flat bar 36 and the angle 38 substitute for the role of the iron plate 41.

[0025]
