Description

  The present invention belongs to the technical field of load-bearing face materials used in the wooden frame construction method, and in particular, the load-bearing face materials are brought into contact with each other side by side (hereinafter referred to as “parallel contact”). The present invention relates to a method for forming a load bearing member, and an apparatus for manufacturing a load-bearing face material configured to execute this forming method.

  The load bearing surface material used in the wooden frame construction method has a form in which each of the opposing side surfaces of a predetermined rectangular (prism-shaped) wood shaft material is juxtaposed to form a flat plate shape, which has been used .

  For example, in patent document 1, while arranging the wooden shaft material of the same dimension sideways in the horizontal direction, the uneven surface formed on the side surface of the wooden shaft material is adapted to form a flat plate surface, and the horizontal direction parallel to the flat plate surface A load-bearing face material integrated by tightening with a metal wire penetrating the wire has been disclosed.

  Further, in Patent Document 2, a plurality of insertion holes are formed in a zigzag manner in a stacking direction of a laminated material in which a plurality of wood shaft members are laminated, and a reinforcing member is inserted into these insertion holes to be integrated. A proof bearing material has been disclosed.

  By the way, an ordinary apparatus for producing a load bearing surface material was originally a large-scale apparatus provided with mechanisms for performing a plurality of steps in order to manufacture a laminated material by press-bonding the laminated material as an integrated and wide plate material. For example, the laminated timber manufacturing apparatus shown in Patent Document 3 includes a log supply device, a log cutting device, a primary lamina raw plate manufacturing device, a primary lamina finishing processing device, a secondary lamina manufacturing device, a tertiary lamina manufacturing device, a veneering device, etc. It was the structure arranged so that it might cooperate suitably.

  On the other hand, the manufacture of the load bearing members having the configurations shown in Cited Document 1 and Cited Document 2 did not require such a large-scale apparatus. This is because the opening for the metal wire and the reinforcing material to be inserted into the wood shaft material can be formed with existing drilling equipment and small-scale equipment such as a hand drill, and does not require large equipment such as a press. It was.

JP 2007-146388 A Japanese Patent Laid-Open No. 10-338991 JP-A-10-146808

  In addition, the reason for supporting the production of the load bearing face materials shown in Patent Documents 1 and 2 with existing equipment is that they were not widely used due to the strength problems of the load bearing face materials in the side-by-side configuration of the wood shaft material. It was the cause. In other words, the load-bearing face materials shown in Patent Documents 1 and 2 are not required to be mass-produced. As a result, there are circumstances in which a dedicated manufacturing apparatus has not been developed due to cost factors and strength problems.

  However, the present applicant has succeeded in developing a load bearing member formed by juxtaposing rectangular wooden shafts that solves the strength problem. The structure of this load-bearing face material is a long fastening wire material (so-called all screw-like wood for wood) that penetrates at least two wood shaft materials from a plurality of locations on one side by juxtaposing a plurality of wood shaft materials. Screws are inserted and fixed, and a plurality of wood shaft members are configured in a flat shape and integrated. In addition, the number of the wood shaft materials which let each fastening wire penetrate is 2-3.

  The load bearing surface material having such a configuration may have different surface yield strength depending on the number of penetrations of each fastening wire, the penetration location, and the penetration direction, and if performed manually, there is a problem in uniformizing the strength of the face material strength. there were. Moreover, in manual work, since it took time to manufacture per face material, it was also a factor of cost increase. In addition, looking at the increase in demand for residential buildings by the wooden frame construction method using wood that was suitable for the future Japanese climate, cost reduction through efficient production using dedicated manufacturing equipment suitable for mass production is desired. It was.

  Therefore, the present invention was created based on the above background, and for the load bearing surface material of the wooden shaft material configuration used in the wooden frame construction method, a forming method that stabilizes the quality and is excellent in mass productivity, and A manufacturing apparatus configured to perform this forming method is provided.

  In order to solve the above-described problems, the load bearing surface material having a wooden shaft material structure used in the wooden frame construction method according to the present invention is formed by the following method.

  That is, the side surfaces of at least two rectangular wood shaft members are brought into contact with each other side by side (hereinafter referred to as “parallel contact”), and a plurality of pieces are arranged in the adjacent tree shaft direction from one side surface of the juxtaposed wood shaft material. An initial fastening material is formed by penetrating the fastening wire, and then a new wooden shaft material is juxtaposed to one side surface of the initial fastening material, and a plurality of fastening wire materials are penetrated from one side surface. It is characterized in that a flat load bearing member having a desired width is formed by sequentially repeating the step of integrating with the preceding fastening material. Here, the fastening wire is a long screw for wood (a male screw for wood).

  In addition, the juxtaposition is characterized by conformity between a concave shape formed on the side surface of the wood shaft material and a convex shape.

  Next, the bearing device for producing a load-bearing face material according to the second aspect of the invention configured to execute the forming method according to the first aspect of the invention is configured as follows.

  That is, a carry-in / out means that is held by the frame and horizontally moves the load bearing surface material or the wood shaft material in the longitudinal direction, and a fixing means that holds a plurality of wood shaft materials juxtaposed at a predetermined position of the carry-in / out means, An opening means for drilling a pilot hole for allowing a fastening wire to penetrate from one side surface of the juxtaposed wood shaft material, a penetration means for screwing the fastening wire into the pilot hole, and a load bearing surface material in a short direction It is characterized by comprising moving means for moving to.

  Further, the moving means includes a lifter that raises the load bearing member and separates it from the carry-in / out means, and a plurality of rollers that rotate the shaft so that the lifter moves the load bearing member in the short direction. It is a feature.

  The opening means and the penetration means are arranged in a moving mechanism that enables parallel movement. By this moving mechanism, it contributes to the adjustment of the processing position of the held opening means and the penetration means, and assistance in maintaining the processing accuracy.

  Furthermore, the penetration means is characterized by comprising position adjustment means that can be aligned with the machining position of the opening means. As the position adjusting means, one having a switching function between the opening means and the penetration means for an arbitrary processing position is preferable.

  Note that the opening means and the penetration means do not need to be provided with separate drive sources, and in the drive operation of the opening means and the penetration means, it is performed by exchanging a bit attached to the output shaft of one drive source. May be. For example, the pilot hole drill may be attached to the output shaft of a drive source such as an electric screwdriver by a connecting member, while the screw bit driver bit is attached to the output shaft to perform the penetration work.

  The method for forming a load bearing surface material of the present application does not pass through all the wood shaft members that are juxtaposed, but at least a plurality of adjacent wood shaft materials are joined together by fastening wire rods, and the joints are joined to the bearing surface. The strength is improved because it is dispersed on the entire surface of the material. For example, when the load bearing face material of the present application is used as a load bearing wall, the wall magnification is remarkably improved.

  This is because even if a predetermined external force repeatedly acts on the load bearing surface material, each fastening wire penetrated into a plurality of locations is individually bound to the adjacent wood shaft materials, so that the yield strength is reduced. Because there is no. In addition to this, stress relaxation and creep caused by the action of long-term aging are limited to each fastening wire, so that the proof stress can be stably maintained.

  In addition, according to the above-described configuration, in the forming method in which the side surfaces facing each other of the same-sized wood shaft material are juxtaposed, the manufacturing device for the load-bearing surface material has the fastening wire material for joining the wood shaft materials at an appropriate position. Since it can be easily penetrated, the quality can be stabilized, and it is easy to carry in / out and change the width, so it is excellent for mass production and high-mix low-volume production.

  Further, the upper surface fixed cylinder 31 is arranged at a position deflected to the front side. This is for fixing a position closer to the machining position by the opening means 4 and the penetration means 5 described later. On the other hand, the rear surface fixing cylinder 32 is disposed substantially rearward of the center of each divided portion of the frame 21, and these three extend the rod 32 a in synchronism and push the load bearing surface material p forward.

  The opening means 4 is disposed at a position that forms a horizontal plane of the cutout portion of the frame 21. The hole opening means 4 starts drilling from the front side surface (wood scene) of the load bearing surface p, and drills a pilot hole h of a predetermined diameter that spans at least two wood shaft members 9. This is a so-called hand drill with 41 attached to the tip side. And like the upper surface fixed cylinder 31 and the rear surface fixed cylinder 32, it arrange | positions via the parallel displacement mechanism 6 in each division part according to the 3 division | segmentation aspect of the flame | frame 21.

At this time, since the load bearing surface p is supported by the small roller conveyor 83, the load bearing surface p can be easily moved in the front-rear direction.
[Operation of the present method and apparatus]

  Next, a method for forming the load bearing face p according to the present method will be described based on the operation of the apparatus 1.

  First, at least two wood shaft members 9 and 9 are carried in from the right side of the frame 21. Here, the wood shaft material 9 to be carried in forms a concave strip 91 having a concave strip shape by being dented over the entire length of one side of one opposing side surface on the long side, and on the other side. A ridge 92 having a ridge shape conforming to the ridge 91 is formed over the entire length. The ridge 92 is formed by chamfering two ridge lines on the long side. On the other hand, the distal end side that protrudes outside the concave strip 91 is subjected to curved surface processing as shown in FIG. 6A in consideration of damage and the like in addition to the improvement of the compatibility with the convex strip 92.

  The wood shaft material 9 is smoothly loaded by the roller conveyor 22 of the loading / unloading means 2 while keeping the longitudinal side thereof in the left-right direction of the frame 21. Further, the wood shaft members 9, 9 are held in the frame, and the concave stripes 91 and the convex stripes 92 are fitted in parallel with each other. In addition, the wood shaft material 9 which has been in the juxtaposed state after the carry-in is aligned so that the ridge 92 is on the front side.

  Next, the two wood shaft members 9, 9 that are carried in are fixed at predetermined positions of the frame 21. As a fixing mode, the rod 32a of each rear surface fixing cylinder 32 advances to the front side, and the two wooden shaft members 9, 9 are brought into contact with the push plate 32b, and the concave strip 91 and the convex strip 92 are brought forward in an adapted state. After the extrusion, the front wooden shaft 9 is brought into contact with and held by the predetermined column 21a of the frame 21, the rod 31a of the upper surface fixing cylinder 31 is pushed down, and the upper surface of the wooden shaft 9 is lowered by the pressing plate 31b. This is done by pressing against the roller conveyor 22.

  After fixing the two wooden shaft members 9, 9, the drill 41 is made with respect to the front side surface of the wooden shaft member 9 (the wood scene of the load bearing surface material p) with the respective opening means 4 arranged at three positions of the frame 21. After adjusting the position of the tip of each, an opening is started in the direction of the adjacent wooden shaft, and a pilot hole h having a depth straddling the two wooden shaft members 9 is opened. In this work, the opening 7 can be smoothly opened by holding the opening means 4 by the folder 7, adjusting the position in the left-right direction by the parallel movement mechanism 6, and assisting the forward / backward movement.

  After the pilot hole is opened, the opening means 4 is temporarily retracted to the front side by the parallel movement mechanism 6 and the leading end side of the fastening wire b is inserted into the pilot hole position. Next, the folder 7 is rotated to place the penetrating means 5 at the position where the opening means 4 was present, and then the screwdriver 51 of the penetrating means 5 is rotated to penetrate (screw) the fastening wire rod b.

  When the penetration of the fastening wire b is completed, the two wood shaft members 9, 9 are integrated, and this becomes the initial fastening material p0. After completion of the initial fastening material p0, first, the penetrating means 5 is retracted to the front side, and the fixing by the fixing means 3 is released. When the unlocking is confirmed, the rods 82 of the lifters 81 of the two moving means 8 arranged on the left and right of the frame 21 are raised. The plurality of small roller conveyors 83 that are parallel to the two rows ascend as the rod 82 rises, pushes up the initial fastening material p0 and separates it from the roller conveyor 22 of the loading / unloading means 2 and enables movement in the front-rear direction.

  Next, after the initial fastening material p0 is moved to the rear side, the lifter 81 of the moving means 8 is lowered. After descending, one wood shaft material 9 is carried into the front side of the initial fastening material p0, and the concave strip 91 of the wood shaft material 9 and the convex strip 92 on the front side of the initial fastening material p0 are fitted and juxtaposed.

  When the parallel arrangement is completed, the rear surface fixing cylinder 32 and the upper surface fixing cylinder 31 are similarly activated to fix the additional wood shaft material 9 and the initial fastening material p0 to the frame 21. After the fixing is completed, the opening means 4 is positioned at a position different from the position where the fastening wire b has been previously inserted, and a pilot hole h straddling at least two wood shaft members 9 is opened. The fastening wire b is penetrated by the penetration means 5. In addition, the pilot hole h and the fastening wire material b are good also as length (depth) which straddles three wooden shaft materials.

  After the penetration of the fastening wire b, the penetration means 5 is retracted and the moving means 8 is activated to move the load bearing surface material p composed of the initial fastening material p0 and the added wood shaft material 9 to the rear side, so that a new The wood shaft material 9 is carried into the front side of the load bearing surface material p and brought into a juxtaposed state.

  Thereafter, fixing, pilot hole opening, fastening wire penetration, fixation release, rearward movement, and wood shaft material loading are repeated to form a load bearing surface p made of a predetermined number of wood shaft materials 9. After the formation of the load bearing face p, the backward movement is omitted, and the load 21 is unloaded from the left side of the frame 21 after being fixed.

  The load bearing surface material p completed by the above forming method can be appropriately used as a load bearing surface structure of a wooden frame construction method. In addition, when using the load bearing surface material p as a wall surface, for example, in order to obtain a joint surface with a base or a girder, it is desirable to cut the end surface as necessary to obtain a smooth surface. This is because, depending on how the wooden shaft member 9 is fixed, some unevenness is generated on the end face of the load bearing member p.

That is, two or three rectangular wooden shaft members having the same cross-sectional shape are brought into contact with each other in parallel with each other, and screws for wood are screwed into a plurality of locations along the axial direction of the wooden shaft from one side surface. Forming an initial fastening material that is penetrated and fastened, and then abutting a new wooden shaft material in parallel with one side surface in the width direction of the initial fastening material, and from the new wooden shaft material The process of screwing and inserting wood screws into a plurality of locations along the axis direction of the wood axis toward the initial fastening material is repeated a predetermined number of times by bringing a new wood axis material into contact with the side surfaces in the width direction sequentially. According to the process, a flat load-bearing face material having a desired width with the one wood shaft material as a thickness is formed.

Further, the abutment in which the rectangular wooden shaft members are axially parallel to each other is characterized by conformity between the concave shape formed on the side surface of the wooden shaft material and the convex shape.

Further, the moving means comprises a lifter that raises the load bearing member and separates it from the carry-in / out means, and a plurality of rollers that rotate the shaft so that the lifter moves the load bearing member in the width direction. It is said.

The method of forming a load bearing surface material of the present application does not penetrate all the wood shaft members that are in contact with each other, but at least a plurality of adjacent wood shaft materials are joined together with screws for wood , and the joints are made to withstand strength. The strength is improved because it is dispersed throughout the face material. For example, when the load bearing face material of the present application is used as a load bearing wall, the wall magnification is remarkably improved.

This is because even if a predetermined external force repeatedly acts on the load bearing surface material, each wood screw penetrated into multiple locations is individually bound to the adjacent wood shaft materials, resulting in a decrease in strength. Because there is no. In addition to this, stress relaxation and creep caused by long-term aging are limited to each wood screw , so that the yield strength can be stably maintained.

Further, the apparatus for manufacturing load bearing surface material, the above structure, in the formation method comprising the sides each other facing wooden shaft material having the same dimensions and contact, as appropriate wood screws to bind the wood shaft member to each other The quality can be stabilized because it can be easily penetrated into the position, and it is easy to carry in and out and change the width.
