Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a structure of a floor formed of floor panels and a construction method thereof.

[Conventional technology and problems to be solved by the invention] In the conventional method of floor construction, the joists are fixed to the beams at the construction site, and then
The floor base (floor structure) was formed by fixing a board (surface material) for pasting on top of it. However, this method requires a large amount of work at the site, takes time, and is dangerous during work.

Therefore, in order to simplify the work and obtain a floor structure with a finish that is comparable to that obtained using the conventional construction method, we manufactured a floor panel in which the floor part was made into a panel in advance. Traditionally, it has been used to construct subfloors.

Conventional floor panels are generally of a framework type with side joists arranged at both ends of the surface material, and such framework type floor panels have two types:
There are yatoi type and ■mounted type.

However, as mentioned above, all frame type floor panels have side joists at both ends of the surface material, so in the floor base that is formed, two side joists are located at the joint between adjacent floor panels. As a result, there is a problem in that the volume of timber increases compared to conventional construction methods.

Furthermore, in the case of the butting type (2) above, the side joists are in the form of a simple square prism and there is no retaining part, so there is a problem that a step occurs at the joint between adjacent seat panels.

In addition, the side joists of the above-mentioned Yatoiji type (■) have a square prism shape, but on the outer surface of each side joist (the surface that contacts the side joist of the floor panel that contacts liJ), there is a longitudinal direction at a predetermined position. A groove is formed that extends from one side to the other, and by inserting identical orotto nuts into the grooves of both side joists that touch each other during installation and locking both joists, the joint between adjacent two seat panels can be fixed. This prevents steps from forming in the area. However, this yato-seed type requires additional processing in advance and is difficult to install, which is another problem.

Furthermore, in the mounting type (■) above, when looking at the contact surfaces of the side joists that contact each other in cross section, one side has a 14-shaped shape and the other side has an inverted shape, so that they interlock with each other when they come into contact. The above-mentioned level difference is prevented from occurring by shaping and locking the joists on both sides. However, this pre-mounted type also has the problem of requiring extra processing in advance.

Therefore, an object of the present invention is to form a floor panel that does not increase the volume compared to the structure of the floor section using conventional construction methods, can prevent steps from forming at the joints, and is easy to construct. The purpose of the present invention is to provide a floor structure and a construction method thereof.

[Means for solving espionage problems]

The present invention provides a floor panel for start-up, comprising at least two joists arranged in parallel and a surface material arranged on the surfaces thereof;
Or, a floor structure consisting of two or more basic floor panels arranged side by side with the side edges of their facing materials in close contact with each other, and the above-mentioned starting floor panels are arranged at both ends of the facing materials. A side joist is installed at each side, and at one end, the side edge of the facing material and the outer edge of the side joist coincide, and at the other end, the side edge of the facing material is approximately at the widthwise center of the side joist. The basic floor panel has a side joist provided only at one end of the surface material, and the side end of the surface material is located approximately at the widthwise center of the side joist. The above object has been achieved by providing a floor structure characterized by the following.

Further, the present invention provides a method suitable for forming the structure of the floor section, in which a plurality of pillars in a first row standing vertically on one side surrounding a predetermined space in which the floor section is formed is adjacent to the inside of a plurality of columns.

Next, the basic floor panel according to claim (1) is placed so that the surface material of the other end where no joist is provided is placed on the side joist of the other end of the start-up floor panel, and as necessary. Furthermore, one or more basic floor panels are placed one after another with the surface material of the other end of each non-joisted side placed on top of the side joist of one end of the previous basic floor panel. The present invention provides a construction method for a floor structure characterized by:

[Effect]

In the structure of the floor section of the present invention, first, a starting floor panel is placed in a predetermined position, and then a joist-less base floor panel is installed on a side joist located at the other end of the starting floor panel. When placing the basic floor panel with the surface material of the other side end (hereinafter also referred to as the non-installation side end) and laying the basic floor panel next as necessary, the non-use side end Place the surfacing material on the side joists of the preceding basic floor panel, and if necessary, place other basic floor panels in sequence in the same way, and place the surfacing material on the end of each non-use side. The structure of the floor is formed by fixing these to the joists on which they are respectively placed.

〔Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view showing an example of a floor panel used for forming the subfloor (floor structure) of the present invention.
b) are the initial floor panel and the basic floor panel, respectively. FIG. 2 is a perspective view for explaining the method of laying the floor panel, and FIG. 3 is a schematic plan view showing an example of the structure of the floor section.

The floor panels shown in FIG. 1 are all of the vertical and horizontal type with surface materials arranged on the surfaces of a plurality of joists.

In the initial installation floor panel A shown in FIG. 1(a), side joists 2 and 21 are provided at both ends of the back surface of the facing material 1, and at one end (left in the figure), the side joists 2 and 21 The side edge 1a and the outer edge of the side joist 21 coincide, and at the other side edge (fabric in the figure), the side edge 1a of the surface material l is located approximately at the center of the side joist 2 in the width direction,
The remaining surface of the side slats 2 that remains exposed is used as a mounting portion 2a for an adjacent floor panel.

On the other hand, in the basic floor panel B shown in FIG. 1(b), one side joist 2 and two inner joists 3 are arranged on the back side of the surface material 1. In the side joist 2 disposed at one end of the basic floor panel B, the side end 1a of the surface material 1 is the width of the side joist 2, similarly to the initial installation floor panel A. The remaining surface of the side joist 2, which is located approximately in the center of the direction and left exposed, is used as a mounting portion 2a for an adjacent floor panel. The other end of the basic floor panel B is a non-use end 1b where no joist is provided.

The method for laying the floor panel will be explained according to FIG. 2 (as necessary, it is also shown in phantom lines in FIG. 1).

First, the initial installation floor panel A is pasted at a predetermined position.

Next, the surface material of the non-use side end portion Ib of the basic floor panel B is placed on the mounting portion 2a of the side joist 2 of the previously installed initial floor panel A, and the panel B is arranged.

If necessary, when attaching another basic floor panel (not shown), place the surface material of the non-functional side end on the mounting part of the above-mentioned basic floor panel B installed above, and then attach the basic floor panel. Place B.

If further necessary, the basic floor puffers B2, B,... (not shown) are arranged in the same manner one after another, and the predetermined position of the surface material on the non-use side end of each panel is moved to the side. Fix it to the joists. In this way, after each side edge of the surface material of each floor panel is placed in close contact with each other, the surface material placed on the joist is fixed, thereby forming a floor portion of a desired width. Incidentally, it is sufficient to lay only the first basic floor panel B.

The floor panel applied to the present invention will be explained in further detail with reference to the drawings.

As the surface material 1 constituting the initial installation floor panel A, for example, plywood, O3B, LVL, or other surface material boards can be suitably used.

It goes without saying that the width, length, and thickness of the surface material 1 can be changed arbitrarily as necessary, but the length of the surface material 1 is 1820 to 3640 mm, and the thickness is 9 to 15 mm. This can be listed as a preferable range. In addition, floor panel A for initial installation
The width a (the length between the outer edges of both side joists) is 800 to 870
謹 can be mentioned as a preferable range. However, normally, the above a and L are standardized and used. - For example, a=800m, L=1820.2730 or 364
It is 0. In addition, when L is long, two surface materials may be adhered in the length direction.

As the joists 2.3, various square timbers such as joists, for example, can be used, and the number of joists can be changed arbitrarily. and,
It is preferable that the width of the joist is 30 to 50 m and the height is 45 to 60 m.

In addition, in the case of the basic floor panel B, it can be formed of the same material as the initial installation floor panel A, except that the convergence of the surface material 1 itself constituting it is preferably 910 to 980III11.

The width of the surface material l of the basic floor panel B is usually larger than the width a of the basic floor panel B itself.

Next, one implementation of the method of the present invention! This will be specifically explained using an example of forming a floor structure (subfloor) shown in FIG. 3.

In FIG. 3, numerals 10 to 13 are pillars erected to surround a predetermined space in which a floor portion is formed, and each pillar consists of a pair of upper and lower pillars in the figure. Furthermore, beams 14 are provided between the columns 10 to 13 arranged at the upper and lower sides of the figure, respectively.

The center-to-center spacing between columns in the horizontal and vertical directions in the figure is 910 m and 1820 mm, respectively. The initial floor panel A to be used has a width of 800+a, which is shown in Fig. 1 and is approximately equal to the in-plane spacing between the columns in the horizontal direction, and the basic floor panel B has a width of 800+a, which is also shown by b, which is approximately equal to the in-plane spacing between the columns in the horizontal direction. 910 degrees, which is equal to the center-to-center spacing above, and 1820 degrees, where the length shown by L in Figure 2 is equal to the center-to-center distance between columns (same as between beams) in the vertical direction.
mg+.

First, a first row of pillars erected in an example of the space,
The starting floor panel A is placed inside the pair (plurality) of pillars 10 at the starting end position as described above. In this case, in the length direction (vertical direction in the figure), the panel A is arranged between the cores of the beams 14 and 14 (the same applies to the other panels).

Next, as described above, the first basic floor panel B is placed on the mounting portion 2a of the side joist 2 of the above-mentioned initial installation floor panel A with the surface material of its non-use side end ib placed on the mounting portion 2a of the side joist 2 of the preceding floor panel A for initial installation. Arrange in the same way. At that time, the corner portion corresponding to the pillar 11 is cut out in advance and a notch is made.

Thereafter, the second basic floor panel B is attached to its non-working side end ib
The surface material is placed on the mounting portion 2a of the side joist 2 of the first basic floor panel B and arranged in the same manner. At that time, as in the case of the front installation, a notch is made in the part that corresponds to the pillar 12.

After arranging one starting floor panel A and two basic floor panels B as described above, apply the surface material on the non-use side end of each basic floor panel placed on the joists. It is fixed to the joists, for example, with adhesive and nails.

According to this embodiment described in detail above, there is no need to fix the joists individually to the beams at the construction site, and by simply arranging each floor panel as described above and fixing it at a predetermined position, it is possible to It is possible to easily construct a subfloor with the same volume and finish as when using the construction method.

Since the above-mentioned starting floor panel A is arranged between the inner sides of adjacent columns, no processing such as notches is required.

In addition, since no notches are made in the side edges of any floor panels where the side joists 2 are installed, the side edges are always connected to the beams 1.
4 and does not require special reinforcement.

Furthermore, the second basic floor panel B can also be laid to match the inside of the pillar 13 by simply making a notch in the part that corresponds to the pillar at the non-use side end.

When three people constructed a subfloor of about 55 parts based on the embodiment described above, the required time was 1 hour and 20 minutes.

On the other hand, when four people constructed a subfloor of about 50 sections of the same configuration using conventional construction methods, the time required was 2 hours and 53 minutes.

In addition, in the case of conventional floor panels, approximately 50M of subfloor is
The time required for manual construction was more than 2 hours for both the pierce type and the mounting type, and it took even longer for the Yatoi-jitsu type.

As described above, it is clear that according to the present invention, it is possible to efficiently construct a subfloor in a short time and with the same small volume and excellent finish as in the case of construction using conventional construction methods.

Further, by using the initial floor panel and the basic floor panel, the floor structure of the present invention can be easily and safely constructed at the construction site at the time of construction.

In addition, cutouts for protruding parts such as columns, studs, braces, etc. can be performed on-site at the time of construction.

Furthermore, the floor panel of the present invention is particularly suitable for construction of a second floor subfloor having few protrusions as described above.
