Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor structure that is used to store a floor surface material and a pillar that are joined to a beam of a wooden building.
[0002]
[Prior art]
In a two-story wooden frame construction method, a beam is joined to a through pillar, and a second-tier pipe pillar is joined to the top end of the beam. These columns and beams are usually joined by appropriate joining hardware or joint processing. Then, the floor of the second floor provided in such a shaft frame structure secures the rigidity of the floor structure surface, as shown in FIG. It is often joined to. In this case, in the joint portion between the pillars 93 and 94 and the flooring material 91, the pillars 93 and 94 win as a result (the pillar wins) as a result.
[0003]
[Problems to be solved by the invention]
If the column wins over the floor material joined to the top of the beam as described above, the edge of the floor material needs to be cut out in accordance with the cross-sectional shape of the column at each column position. This notch processing is performed at a factory or on site, but in any case, the labor of the processing leads to a decrease in construction efficiency, and waste material due to the notch is also generated.
[0004]
Furthermore, when pre-cutting a large number of flooring materials at the factory, it takes time to manage various types of flooring materials with different notch positions according to the mounting site, and also at the construction site, for each mounting site. It takes time and effort to find the corresponding member.
[0005]
In addition, if there is no joist under the notch at the location where the floor material is cut out to match the pillar shape, it is necessary to attach a receiving base for supporting the floor material to the side of the column. Occurs.
[0006]
The present invention has been made to improve such inefficiency, and provides a novel floor structure capable of realizing a space that does not require the formation of a notch in accordance with the column position in the floor surface material. It is said.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the floor structure of the present invention is a column base in which a beam is arranged with its material core aligned with a designed module core, and a flat joint plate is coupled to one end of a tenon pipe. The metal fitting is inserted through a drift pin or a bolt that penetrates the beam in the width direction in a state where the tenon pipe is inserted into a fixing hole formed in the beam core and the joining plate is erected on the beam core. The floor material is affixed to the top of the beam with a certain overlap width in a state where the floor material has escaped from the beam core by half of the thickness of the joining plate. A pipe column that is also affixed to the joists installed between the beams and is formed with a slit that coincides with the core at the lower end, and the floor surface in the state where the column base metal joint plate is inserted into the slit Standing on the material and joined in the direction perpendicular to the slit And wherein the through drift pin or bolt through the Kanbashira and the tubular column and the column base hardware linked.
[0008]
In other words, in this floor structure, the floor surface material affixed to the top of the beam and the column erected on the beam, the column is a tube column, and the portion protruding on the beam is formed in a flat plate shape The beam and the pipe column are connected to each other through the column base hardware, and the floor material is laid between the beam and the pipe column. A portion (joining plate) protruding on the beam of the column base metal is erected along the material core of the beam, and a floor surface material is brought into contact with the joining plate and attached to the beam. As a result, the floor surface material wins over the column, and it is not necessary to provide a notch in the floor surface material even at the column position. The flooring material will be attached to the beam in a state where only half the thickness of the joining plate has escaped from the beam core, but the flooring material is attached to both sides of the joining plate. By placing the joining plate in the joint part of the tube, the standing state of the pipe column is also stabilized.
[0009]
For the column base metal, it is preferable that a joining plate is coupled to one end of the tenon pipe, and a connecting hole for inserting a bolt or a drift pin is formed in each of the tenon pipe and the joining plate. According to this, the processing required for the beam is only a fixing hole for inserting the tenon pipe and a pin hole penetrating in the beam width direction perpendicular to the fixing hole, and the processing is easy.
[0010]
Furthermore, in the present invention, the beam is arranged with the material core aligned with the designed module core, and the length and width of the floor surface material are retracted from the module core by a dimension capable of changing the plate thickness of the joining plate. By forming it in a size, it is possible to standardize the reserve dimensions for the module cores of all floor materials. Thereby, even when a large number of flooring materials are pre-cut at a factory, their sizes can be made common to improve member management. In addition, for the beams arranged in the outer periphery of the building, a strip with the same thickness as the flooring material is pasted on the top edge of the outer periphery of the beam, and a pipe column is placed on the flooring material and the strip. By standing, the accommodation of the outer peripheral portion can be made common.
[0011]
The floor structure of the present invention was developed mainly for implementation on floors of two or more floors where the rigidity of the floor structure is required in a building using a wooden frame construction method. It can also be applied to prefabricated construction methods and two-by-four construction methods.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0013]
The floor structure of the present invention is implemented using a column base hardware as shown in FIG. The illustrated column base 1 includes a cylindrical tenon pipe 11 and a flat joining plate 12 coupled 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 thickness center of the joining plate 12 coincide with each other. The tenon pipe 11 and the joining plate 12 are formed with a plurality of connecting holes 111 and 121 for inserting drift pins and bolts, respectively. The connection hole 111 of the mortise pipe 11 is formed in a direction orthogonal to the joining plate 12 in principle, but may be formed to be parallel to the joining plate 12 in a special part. In the illustrated embodiment, both the connecting holes 111 are formed in the mortise pipe 11.
[0014]
2 and 3 are exploded views of the 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.
[0015]
This floor structure is composed of a beam 2, a floor surface material 3 stuck on the beam 2, a pipe column 4 standing on the beam 2, and the column base 1 described above. Hereinafter, the accommodation of these members will be described along the construction procedure.
[0016]
A fixed hole 21 for inserting the tenon pipe 11 of the column base 1 and a plurality of pin holes 22 penetrating the beam 2 in the width direction perpendicular to the fixed hole 21 are formed in the beam 2 in advance. . The fixing hole 21 is formed at a position that coincides with the module core N of the column, but this module core N also coincides with the material core of the beam 2 in principle. The tenon pipe 11 of the column base 1 is inserted into the fixing hole 21, and the column base 1 is fixed to the beam 2 via a drift pin 51 or a bolt inserted into the pin hole 22 from the side of the beam 2. . Thereby, the joining plate 12 of the column base 1 protrudes on the beam 2 and stands upright. When the connection hole 111 of the mortise pipe 11 is orthogonal to the joining plate 12, the direction of the joining plate 12 coincides with the material core of the beam 2.
[0017]
Further, when the joist 6 is joined to the side surface of the beam 2, for example, groove-shaped joist supports 7 as illustrated are attached to the side surface of the beam 2 at an appropriate interval.
[0018]
As the floor surface material 3, a structural plywood or a similar plate material is used. The floor covering 3 may be preliminarily laid on the upper surface of the joist 6 between the beams, but as shown in FIG. 1, with the joist 6 attached to the lower surface of the floor covering 3 in advance, It may be constructed between the beams together with the joists 6.
[0019]
The floor material 3 is mounted on the beam 2 with an edge portion of which overlaps approximately half the beam width, and is fixed to the beam 2 with a nail or a screw. Strictly speaking, as shown in FIG. 4, the edge of the floor surface material 3 is mounted on the beam 2 in a state where it escapes from the material core (module core N) of the beam 2 by half the thickness of the joining plate 12. Since the joining plate 12 has a thin plate shape, the floor surface material 3 can be mounted to a position very close to the material core of the beam 2 without providing a notch at the edge thereof. Moreover, the edge part of the flooring material 3 can be mounted with the fixed overlap width with respect to the beam 2 irrespective of a column position.
[0020]
Usually, the floor material 3 is stuck on both sides of the beam 2. Therefore, a joint corresponding to the thickness of the joining plate 12 is formed between the floor materials 3 adjacent to each other via the beam 2, and the joining plate 12 is accommodated in this joint.
[0021]
As for the beam 2 arranged on the outer peripheral part of the building, the floor material 3 is stuck only on one end of the beam 2, so that the same thickness as the floor material 3 is provided on the outer peripheral side of the beam 2 as shown in FIG. The band plate 8 having the above is pasted so that both sides of the joining plate 12 are aligned at the same height. The width of the strip 8 is a dimension obtained by subtracting half of the thickness of the joining plate 12 from half of the width of the beam 2.
[0022]
After the floor material 3 is attached to the top end of the beam 2 in this way, as shown in FIG. 3, the pipe column 4 is connected to the joining plate 12 protruding from the joint of the floor material 3. The tube column 4 is previously formed with a slit 41 at the lower end thereof, and a plurality of pin holes 42 that are orthogonal to the slit 41 and penetrate the tube column 4 in the width direction. In principle, the slit 41 is formed so as to coincide with the material 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 material 3. And the pipe column 4 and the column base 1 are connected through the drift pin 52 or the bolt inserted into the pin hole 42 from the side surface of the tube column 4.
[0023]
Here, specific dimensions of each member according to the illustrated form are exemplified. The width of the beam 2 and the pipe column 4 is 105 mm, the thickness of the joining plate 12 is 3.2 mm, and the structural plywood is the flooring material 3. The plate thickness is 24 mm, and the joint width of the floor covering 3 is 4 to 4.5 mm.
[0024]
Thus, according to the present invention, the floor surface material 3 wins over the tube column 4, and the joining plate 12 for connecting the tube column 4 becomes a thin plate shape along the material core of the beam 2, It is not necessary to provide a notch at the edge of the floor covering 3.
[0025]
Further, when the material core of the beam 2 is made to coincide with the designed module core N, the length and width of the floor surface material 3 are retracted from the module core N by a dimension capable of changing the plate thickness of the joining plate 12. By standardizing the size, the member management of the floor surface material 3 can be made efficient.
[0026]
【The invention's effect】
As described above, according to the floor structure of the present invention, since it is not necessary to cut out the floor material at the joint between the beam and the column, the work efficiency in the factory or the field is increased, and the notch processing is performed. Waste material generated in the process is also reduced.
[0027]
Also, since the edge of the flooring material can be affixed to the top of the beam with a certain overlap width, the rigidity of the floor construction surface is strengthened and an auxiliary support for supporting the flooring material is provided. The groundwork can be greatly omitted.
[0028]
Furthermore, according to the present invention, the floor material is processed by standardizing the width and length of all the floor materials to a size that is retracted from the designed module core by a dimension that can avoid the plate thickness of the joining plate. It is possible to make the member management more efficient by sharing dimensions.
[0029]
As a result, consistent improvement in construction efficiency from the member processing stage to the construction stage can be obtained, and construction quality can be improved and costs can be reduced. Such an effect becomes more prominent when the wall and floor members are combined (panelized).
