The prior art is an invention for using wooden materials for a large span frame, but it has the following problems.
(i) In the invention of Patent Document 1, there is no specific disclosure as to the method of embedding inside the wooden material other than the method of dividing and gluing. Although there is mention of joints, the specific relationship between the joints is not explicitly stated, and the parts used for joining are merely conceptually shown. Regarding the joining of the composite materials in the central part of the frame, which is intended in the present application, in Patent Document 1, the joint is exposed, so there is a problem that the aesthetic appearance of the wooden frame is significantly impaired.

(ii) The invention of Patent Document 2 takes into consideration the joining of members at the center of the frame, but it takes time and effort to process the uneven shapes for both wooden materials and reinforcing steel plates, and furthermore, due to the structure, the mating members There is a problem in that it can only be placed from the front of the end face.
Furthermore, although the invention of Patent Document 3 is similar, the divided wood and steel plate are integrated by adhesive, and the lower end surface of the steel material is exposed, so in the event of a fire, the internal steel material quickly becomes hot and the outer peripheral In addition, the adhesive and wood in contact with the steel material also progress to carbonization and lose their integrity, resulting in the loss of their original reinforcing effect.

(iii) In the invention of Patent Document 4, the wood and the internal steel are fixed using fastening bolts and integrated using a shear member, but all of the various methods of engaging the shear member into the wood are time-consuming. In many cases, the shear member arrangement is defined in terms of the arrangement interval in the material axis direction, but in the height direction, although some are illustrated, specific positions are not described. Regarding the longitudinal connection means, it is only described that a joint is formed by extending the steel material, and in a form where the joint is joined at the center of the frame, as with normal steel structures, unless a separate splice plate is used, Since the axis is misaligned and the joining member is exposed, it is aesthetically problematic. Further, as in Patent Documents 2 and 3, since the lower end surface of the steel material is exposed, there is a problem in terms of fire resistance, and there is no specific disclosure regarding the joining for constructing the chevron-shaped frame.

(iv) The invention of Patent Document 5 incorporates a shear member into wooden members arranged opposite each other, and frictionally joins the shear member and the steel material by the tightening force of the bolt. Mechanically, the large diameter drift pin is attached to the steel material. Although a means for arranging the structure without shifting from the structure is shown, the arrangement method is the same as in Patent Document 4, the steel plate is exposed, and there is no specific disclosure regarding the chevron-shaped frame.

(v) The invention of Patent Document 6 discloses a joining hardware for an angle-shaped frame, but if we focus on joining with a climbing beam that is a member to be joined, it is possible to Steel plates are joined together, and the appearance and fire resistance of the wood cannot be solved, which are the technical problems of the joints in the chevron-shaped frame that the present invention aims to solve.

[Embodiment 1]
As shown in FIG. 1, the chevron composite construction material 1 according to the present embodiment is constructed between columns or girder beams that constitute a chevron frame, and is constructed between a pair of ridgelines that constitute a ridgeline portion of the chevron frame. It is provided with a composite member 5 and an angle-shaped composite member 3 which is located in the middle part of the angle-shaped frame, constitutes an angle-shaped part, and serves as a joint between a pair of ridge line composite members 5. Hereinafter, details of the chevron-shaped composite construction material 1 of the present embodiment will be described, including specific dimensions, using as an example a case where it is used in a chevron-shaped frame having a span of 12 m and a ridge corner portion in the center. However, the dimensions shown below are examples of nominal dimensions, and the present invention is not limited thereto. In addition, the expression "same" is based on the nominal value, and it goes without saying that it allows for tolerances in size and shape and clearances necessary for manufacturing, but it also means that the dimensions are larger and the hardening filler is used. It also includes those that result in the same result, such as those that are used to eliminate gaps.

<Ridge line composite member>
As shown in FIG. 3, the ridgeline composite member 5 includes a ridgeline wooden material 15 and a ridgeline steel plate 17 fitted into the ridgeline wooden material 15.

《Ridge wooden material》
The ridgeline wooden material 15 is a structural laminated wood of strength class E120, and has a width of 120 mm, a height of 390 mm, and a length of 5.5 m.
As shown in FIG. 4, the ridgeline wooden material 15 is provided with a first groove 19 over its entire length on its upper surface side. As for the specific dimensions of the first groove 19, the width t _w1 is 12 mm, and the depth H _w1 is 250 mm, which are the same as the thickness t and width H ₂ of the ridgeline steel plate 17 disposed here.
Moreover, at both ends, the first groove 19 is formed axisymmetrically with respect to the reference line BL, that is, at least one side surface of the first groove 19 is aligned with the side surface thereof, and the grooves are integrated adjacent to each other. A second groove 21 is formed toward the center in the axial direction of the material. The specific dimensions of the second groove 21 are that the width _tw2 is 12 mm, the depth _Hw2 is 250 mm, and the length is 300 mm, which is the same width, thickness, and length as the protrusion 9a of the angle steel plate 9. .
Note that the second groove 21 is essential on the side to be joined to the angle-shaped composite member 3, but the second groove 21 formed at the other end is provided for joining to the pillar side. , when not used for joining with the pillar side, there is no need to provide the second groove 21 at the end.

Here, an example of how to decide the arrangement of the first grooves 19 will be explained based on FIG. 4. A reference line BL is set at the center of the ridgeline wooden material 15 in the width direction, and in this example, the first groove 19 is set on the right side of the reference line BL in the illustration.
That is, the left side surface of the first groove 19 is on the same line as the reference line BL, and if the groove width of the first groove 19 is _tw1 , then the center of the first groove 19 in the width direction is It is arranged shifted to the right by t _w1 /2.
Note that the reference line BL is not for the ridge line composite member 5 alone, but for the angle-shaped composite construction material 1 with a span of 12 m formed by joining with the angle-shaped composite member 3.

The arrangement of the first groove 19 with respect to the reference line BL is not limited to the above-mentioned arrangement, and in the case of lot production, it is sufficient to unify the arrangement for each lot, and it may be arranged on the left side of the reference line BL. , the center of the first groove 19 may be aligned with the reference line BL as in the fourth embodiment described later.
In addition, since the reference line BL is set at equal distances from both sides of the ridgeline wooden material 15 toward the center of the width, if there is only one reference line BL, it should be set at the center in the width direction as in the above example. be done. However, the number of reference lines BL is not limited to one; for example, if there are two, one each is placed at an equal distance from the left and right side surfaces, and the first groove is formed according to the above-mentioned rules according to this reference line BL. Place 19. Note that the number of reference lines BL is not limited to one or two, and therefore the number of first grooves 19 is not particularly limited either. Note that the case where there are two reference lines BL will be specifically described in Embodiment 2, which will be described later.

The ridgeline wooden material 15 has a joining through-hole in the ridgeline wooden material at the same position as the joining through-hole 13 of the angle-shaped steel plate provided in the protrusion 9a of the angle-shaped steel plate 9, which will be described later, in the joined state with the angle-shaped composite member 3. 23 (see FIG. 1(b)).

In addition, a hole 27 for a stress transmitting member 27 for a ridgeline wooden material is provided in the ridgeline wooden material 15 as a hole for installing a stress transmitting member 25 such as a drift pin that transmits the stress of the ridgeline steel plate 17 (see FIG. 5). ). The ridgeline wood stress transmission member hole 27 is provided at a position corresponding to a ridgeline steel plate stress transmission member through hole 29 provided in the ridgeline steel plate 17, which will be described later, with the ridgeline steel plate 17 fitted therein.
The ridgeline wooden material stress transmission member hole 27 is bored from one side of the ridgeline wooden material 15 to a depth at least as far as the steel plate.
The stress transmission member 25 to be installed is used to transmit stress between the ridgeline wooden material 15 and the ridgeline steel plate 17, and in the case of a drift pin, the ridgeline wooden material stress transmission member hole 27 may be made non-penetrating. They may be arranged in a staggered manner on the left and right sides, or a plurality of them may be provided above and below. Further, as shown in FIG. 5, in the case of a through hole, a bolt can be used in addition to a drift pin.
Since a drift pin with a diameter of 16 mm is used for the stress transmitting member 25, the diameter of the hole 27 for the ridgeline wooden stress transmitting member is set to be smaller than the diameter of the drift pin, for example, 15 mm to prevent rattling. If a bolt is used, the bolt diameter may be greater than or equal to the bolt diameter; for example, for M16, the diameter is 17 mm.
The stress transmitting member 25 such as a drift pin may be designed so that the ratio of the bending moment to be borne is calculated from the stiffness ratio of the ridgeline steel plate 17 and the ridgeline wooden material 15, and the difference can be transmitted.

《Ridge steel plate》
The ridgeline steel plate 17 has the same length as the ridgeline wooden material 15, and is fitted into the first groove 19 without both ends protruding from the ridgeline wooden material 15, as shown in FIG.
