Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure for accommodating a floor surface material and a column which are joined to a beam of a wooden building.

[0002]

2. Description of the Related Art In a wooden frame construction method of two or more stories, a beam is joined to a through column, and a pipe column on the second floor is joined to the top end of the beam. The joining of these pillars and beams is usually performed by an appropriate joining metal or joint processing. In order to secure the rigidity of the floor structure, the floor on the second floor provided in such a frame structure is provided with a floor material 91 made of structural plywood or the like as shown in FIG. Often joined to. In this case, in the part where the columns 93, 94 and the floor surface member 91 are joined,
As a result, the columns 93 and 94 win the floor material 91 (column win).

[0003]

As described above, in the case where the pillar wins over the floor surface material joined to the top end of the beam, the edge portion of the floor surface material is formed into a cross-sectional shape of the column at each pillar position. It becomes necessary to cut out together. This notch processing is performed in a factory or on-site, but in any case, the labor of processing causes a reduction in construction efficiency, and waste materials due to the notch are also generated.

Furthermore, in the case of pre-cutting a large number of floor coverings in a factory, in addition to the time and effort required for managing various kinds of floor coverings having different cutout positions for each mounting site, the mounting at the construction site is also difficult. It takes time and effort to find a corresponding member for each part.

In addition, if there is no joist below the notch at the place where the floor covering is cut out in accordance with the shape of the pillar, a support base or the like for supporting the floor covering is attached to the side surface of the pillar. It will be necessary to install it.

The present invention has been made in order to improve such inefficiency, and provides a new floor structure capable of realizing a housing which does not require the formation of notches corresponding to the positions of columns in the floor surface material. Is the problem to be solved.

[0007]

In order to solve the above-mentioned problems, in the floor structure of the present invention, a column pedestal having a flat plate-like joint plate at one end stands the joint plate upright on the beam core. The pipe is fixed to the beam in such a manner that the floor surface material is affixed to the top end of the beam in a state where the floor surface material escapes from the core of the beam by half the plate thickness of the joining plate, and a slit is formed at the lower end. It is characterized in that a pillar is erected on the floor surface material in a state where the joining plate is inserted into the slit and is connected to the pillar pedestal.

That is, in this floor structure, in the accommodation of the floor surface material attached to the top end of the beam and the column standing upright on the beam, the column is a tube column and the portion protruding above the beam is a flat plate. The beam and the tube column are connected to each other through a columnar metal fitting formed in a shape, and a floor material is laid between the beam and the tube column. The portion (joint plate) of the pillar pedestal projecting above the beam is made to stand upright along the beam core, and the floor plate is brought into contact with this joint plate and attached to the beam. As a result, the floor covering wins over the pillar, and it is not necessary to provide a notch in the floor covering at the pillar position. The floor surface material will be attached to the beam in a state where it has escaped from the core of the beam by half the thickness of the joining plate, but by attaching the floor material on both sides of the joining plate, By installing the joint plate in the joint part, the standing condition of the pipe pillar is also stable.

It is preferable that the pedestal metal member has a joining plate joined to one end of the mortise pipe and a connecting hole for inserting a bolt or a drift pin into the mortise pipe and the joining plate, respectively. According to this, the beam requires only the fixing hole for inserting the mortise pipe and the pin hole which is orthogonal to the fixing hole and penetrates in the beam width direction, and the processing is easy.

Further, in the present invention, the beams are arranged so that the cores of the beams coincide with the designed core of the module, and the length and width of the floor surface material are such that the thickness of the joint plate can be evaded from the core of the module. By forming the recessed size only, it is possible to standardize the spare dimensions for the module core of all floor materials. As a result, even when a large number of floor coverings are pre-cut in a factory, it is possible to make their sizes common and to efficiently manage members.

The floor structure of the present invention was developed with the aim of being applied to floors of the second floor or higher where the rigidity of the floor structure is required in a building by the wooden frame construction method.
It can also be applied to the prefab construction method and the two-by-four construction method in which the members of the walls and floors are panelized.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

The floor structure of the present invention is implemented by using a column pedestal as shown in FIG. The exemplified column base metal fitting 1 includes a cylindrical tenon pipe 11 and a flat plate-shaped joining plate 12 joined to one end thereof. The tenon pipe 11 and the joining plate 12 are integrated by welding or the like so that the axis of the tenon pipe 11 and the center of the plate thickness of the joining plate 12 coincide with each other. The mortise pipe 11 and the joint plate 12 are each formed with a plurality of connecting holes 111 and 121 through which drift pins and bolts are inserted. The connecting hole 111 of the tenon pipe 11 is formed in a direction orthogonal to the joining plate 12 in principle, but may be formed so as to be parallel to the joining plate 12 in a special portion. In the illustrated form, the mortise pipe 11 is formed with the connecting holes 111 of the both.

2 and 3 are exploded views showing a floor structure according to the most basic embodiment of the present invention, and FIG. 4 is a sectional view showing a completed state of the floor structure.

This floor structure is composed of a beam 2, a floor surface material 3 attached on the beam 2, a pipe column 4 standing on the beam 2, and the above-mentioned column base metal 1. Hereinafter, the accommodation of each of these members will be described according to the construction procedure.

The beam 2 is provided with a fixing hole 21 for inserting the mortise pipe 11 of the column base 1 and a plurality of pin holes 22 which are orthogonal to the fixing hole 21 and penetrate the beam 2 in the width direction in advance. It is formed. The fixing hole 21 is formed at a position corresponding to the module core N of the pillar, and this module core N also basically coincides with the material core of the beam 2. Then, the mortise pipe 11 of the column pedestal 1 is inserted into the fixing hole 21, and the column pedestal 1 is fixed to the beam 2 via the drift pin 51 or the bolt inserted into the pin hole 22 from the side surface of the beam 2. . This allows
The joining plate 12 of the pillar pedestal 1 projects above the beam 2 and stands upright. The joint hole 111 of the mortise pipe 11 has the joining plate 1
When orthogonal to 2, the orientation of the joining plate 12 coincides with the core of the beam 2.

When the joists 6 are joined to the side surfaces of the beam 2, for example, groove-shaped joist metal receiving members 7 as shown in the drawing are attached to the side surfaces of the beam 2 at appropriate intervals.

As the floor material 3, structural plywood or a similar material is used. The floor covering 3 may be preliminarily laid between the beams and attached to the upper surface thereof. However, as shown in FIG. 1, with the joists 6 attached in advance to the lower surface of the floor covering 3, It may be installed between the beams together with the joists 6.

The floor surface material 3 is mounted on the beam 2 with its edge portion having an overlapping width which is approximately half the width of the beam, and the beam 2 is fixed by nails or screws.
Fixed to. Strictly speaking, as shown in FIG. 4, the edge portion of the flooring material 3 is mounted on the beam 2 in a state where it is away from the core of the beam 2 (module core N) by half the thickness of the joint plate 12.
Since the joining plate 12 has a thin plate shape, the floor surface material 3 is
It is possible to mount the beam 2 to a position very close to the core of the beam 2 without providing a notch at its edge. Further, the edge portion of the floor surface material 3 can be mounted on the beam 2 with a constant overlapping width regardless of the position of the pillar.

Normally, the floor material 3 is sandwiched between the beams 2 on both sides thereof.
Is affixed. Therefore, joints corresponding to the plate thickness of the joint plate 12 are formed between the floor surface members 3 adjacent to each other via the beam 2, and the joint plate 12 is accommodated in this joint.

As for the beam 2 arranged on the outer peripheral portion of the building, the floor material 3 is attached only to one end of the beam 2, and therefore, as shown in FIG. The strip plates 8 having the same plate thickness are attached to align both sides of the joint plate 12 at the same height. The width of the strip plate 8 has a size obtained by subtracting half the plate thickness of the joining plate 12 from the half width of the beam 2.

After the floor covering 3 is attached to the top end of the beam 2 in this manner, the pipe column 4 is connected to the joint plate 12 protruding from the joint of the floor covering 3, as shown in FIG. The tube column 4 has a slit 41 formed in its lower end portion in advance, and a plurality of pin holes 42 orthogonal to the slit 41 and penetrating the tube column 4 in the width direction. In principle, the slit 41 is formed so as to coincide with the core of the tube column 4. The joining plate 12 is inserted into the slit 41, and the tube column 4 is erected on the floor surface member 3. Then, the pipe column 4 and the column base 1 are connected to each other via the drift pin 52 or the bolt inserted from the side surface of the pipe column 4 into the pin hole 42.

Here, exemplifying the concrete dimensions of each member according to the illustrated embodiment, the width of the beam 2 and the tube column 4 is 105 m.
m, the plate thickness of the joining plate 12 is 3.2 mm, the plate thickness of the structural plywood that becomes the floor surface material 3 is 24 mm, and the joint width of the floor surface material 3 is 4 to 4.5 mm.

As described above, according to the present invention, the floor surface material 3 wins over the pipe pillar 4, and the joining plate 12 for connecting the pipe pillar 4 is formed in a thin plate shape along the core of the beam 2. Therefore, it is not necessary to provide a cutout at the edge of the floor covering 3.

Further, when the core of the beam 2 is made to coincide with the designed core N, the length and width of the floor surface material 3 are
The flooring material 3 is standardized to a size in which the thickness of the joining plate 12 is set back from the module core N by a size that allows the joining plate 12 to dodge.
The member management can be made more efficient.

[0026]

As described above, according to the floor structure of the present invention, it is not necessary to make a notch in the floor surface material at the joint between the beam and the column, so that the work efficiency in the factory or the site is increased. However, the waste material generated by the notch processing will also be reduced.

Further, since the edge portion of the floor surface material can be attached to the top end of the beam with a certain overlapping width, the rigidity of the floor construction surface is strengthened, and an assist for supporting the floor surface material is provided. It is also possible to greatly omit the basic groundwork.

Further, according to the present invention, by standardizing the widths and lengths of all the floor materials to a size retracted from the designed module core by a dimension capable of passing the plate thickness of the joining plate, It is possible to make the processing size of the material common and to efficiently manage the material.

As a result, it is possible to consistently improve the working efficiency from the member processing stage to the working stage, and to improve the working quality and reduce the cost. Such an effect becomes more remarkable when the members of the wall and the floor are combined (formed into a panel).
