The second wooden member 2 (2-2, 2-4, 2-6,...) Is mainly assembled using two types of wooden members. Since these wooden members become expensive when long wooden materials are used, they are inexpensive by using cheap wood such as thinned wood and processing into short wooden squares of about 2 m or less. The first wooden member 1 and the second wooden member 2 are manufactured.

  In addition, about the 1st wooden member 1, a code | symbol is attached | subjected to the end of the code | symbol 1 in order of odd number -1, -3, -5 ..., and about the 2nd wooden member 2, the code | symbol 2 is added to the end. The numbers are given in the order of even numbers −2, −4, −6..., And the order in which the wooden members 1 and 2 are assembled alternately is shown (details will be described later).

The lengths of the first wooden member 1 and the second wooden member 2 in the member axial direction are preferably the same length, and they are planarly directed in the assembly direction from one side to the other in the left-right direction or the front-rear direction. Thus, the members can be arranged and assembled so as to be dropped alternately from top to bottom.
The convex portions provided at both end portions in the member axial direction of the first wooden member 1 and the second wooden member 2 or the concave portions provided in the central portion (in the case of illustration, or in the intermediate portion) in the member axial direction are formed manually into the square wood. In the case of forming a concave portion or a convex portion, it is formed in a dovetail or a flat trapezoidal convex portion, but in the case of machining, the tip end side in the insertion direction of the convex portion is processed into an arc shape.

  Since there are many common parts of the floor frame structure in the first to fourth embodiments of the present invention, the first embodiment having common elements will be described first, and in the second and subsequent embodiments, the different parts are mainly used.

Processing is applied to the wooden square, and convex portions are formed at both ends in the axial direction, and concave grooves are formed at both side surfaces of the intermediate portion.
When the distance between the central axes of the members arranged parallel to each other at an interval is 2L, each member has a dimension (2L-2b) that is shorter than the dimension 2b at both ends by 2b, and the length in the member axis direction. And a convex portion projecting in the axial direction by the dimension a, and a notch groove 7 and a concave groove having a depth depth of the dimension a connected thereto on both side surfaces in the width direction. The length of each wooden member is 1820 mm, for example. In the first wooden member 1 or the second wooden member 2 in which the concave groove 3 or the convex portion 5 is formed by machining, the dimension a is a-α which is shorter by a slight dimension α. The dimension b is set to b + α which is longer by a slight dimension α.
Hereinafter, each member will be specifically described.

Also, when a horizontal force in the left-right direction is applied, it is supported in the same manner. Therefore, in the floor frame structure of the present invention, the resistance force when a horizontal force in the member axial direction acts on the member can exhibit a greater resistance force than the conventional structure shown in FIG.
In addition, when the floor panel 15 is incorporated in the floor frame structure of the present invention, a resistance structure is formed through the floor panel 15 or integrally with the floor panel 15.

In FIG. 26, the axial direction edge part of the 1st wooden member 1 or the 2nd wooden member 2 of this invention is cut by machining, and the member main body of the 1st wooden member 1 or the 2nd wooden member 2 is shown. One form in the case of forming the front-end | tip part or convex part 4 and 5 of a part is shown.
26 (a) to (c), in particular, as shown in FIGS. 26 (c) and (f), at the distal end portion of the member main body portion, the proximal side convex portion 20 whose upper side or lower side is a short semi-cylindrical shape, Convex portions 4 and 5 are formed at the tip end portion 21 with the upper side or the lower side being arcuate in a side view. In addition, in the 1st wooden member 1 or the 2nd wooden member 2 used as the front-end | tip part of the above forms, the said base end side convex part 20 is formed in the side surface of the center part (or intermediate part) of those member longitudinal directions. , 21 may be fitted, and the bottom part may be a semicircular groove, followed by the formation of the concave grooves 3, 8. In order to fit the base end side convex portion 20, the base end side convex portion 21 is fitted and the base end side convex portion 21 is fitted. In order to do this, the lower portion may be closed, and the cutout groove 7 may be opened on the side and upper side.

In the said embodiment, although the form which forms the groove | channels 3 and 8 in the center part side surface of the member longitudinal direction of the 1st wooden member 1 or the 2nd wooden member 2 was shown, the 1st wooden member 1 or the 2nd wooden member was shown. You may make it form a groove | channel in the intermediate part side surface of the member longitudinal direction of the member 2. As shown in FIG.
When the length dimension of the first wooden member 1 and the length dimension of the second wooden member 2 are the same length dimension, the first wooden member 1 and the second wooden member 2 are substantially in the longitudinal direction as shown in the figure. It is possible to obtain a floor-frame structure having a lattice-like structure with a plane square having a dimension L on one side with a staggered arrangement in which the phase is substantially half-pitch shifted in length in the direction.
