Description

  The present invention relates to a metal fitting suitable for use in, for example, a wooden frame building such as a general house, a unit house, a bungalow, a shrine / temple building, a simple store, a store, a storeroom, a warehouse, and a garage.

  There are various types of joint hardware used for the wooden frame construction method, such as beam receiving hardware and column base hardware, but these are in a state in which they are in direct contact with each other when joining the wires constituting the frame. It joins with. That is, the wires are in a state where they overlap each other in the longitudinal direction or the lateral direction at the joint portion. Since the wire is joined in such a state, a strong fixed state can be obtained, but when the wire is corroded, the wire cannot be entirely replaced from the joined portion.

  For this reason, there exists a difficulty in setting it as the building which can be used for a long period of time.

  In this respect, a wooden frame system unit house as disclosed in Patent Document 1 below has been proposed.

This unit house is configured such that a stud that is attached to an opening of a unit main body is fixed with a drift pin to be detachable.
Japanese Patent No. 2856629

  However, joint portions such as columns and beams other than the inter-columns are fixed using a general joint hardware. For this reason, it will be possible to replace the studs, but not the other parts.

  In addition, the fixing by the drift pin uses a hozo pipe having a part inserted into the beam, and the space between the stud and the beam is supported by the contact between the hozo pipe and the members. For this reason, indentation or the like is likely to occur particularly when a horizontal force is applied, and it is necessary to rely only on the hozopipe, which is difficult in terms of strength.

  Therefore, the main object of the present invention is to make it possible to replace a wire rod such as a column member and to obtain a sufficient strength in terms of structure.

  The means for that purpose is a metal fitting for construction that joins the wires constituting the wooden frame, and is sandwiched between the end faces in the length direction of the wires so that these wires are joined between the end faces. A coupling tool for joining the wire rod to the joint plate having a polyhedral three-dimensional hollow box-shaped outer shell portion, and the outer shell portion including a plurality of joint plates capable of joining the end faces. It is the joint metal fitting for construction in which the holding part which hold | maintains was formed.

  The outer portion is located between the end faces of the wire rods, and maintains the positional relationship between the end surfaces of the plurality of wire rods so that the end surfaces of one wire rod and the side surfaces of the other wire rods do not overlap. Depending on the place of use, the entire circumference may be surrounded, or a part may be exposed. The outer portion is formed in a cubic shape so that the end face of the wire can be fixed to the six faces. For example, the outer face can be formed in a cube shape and the end face of the wire can be fixed to the second, third, fourth, and fifth faces. In addition, it is possible to construct a building having a peculiar form such as a hexagonal hall, and further, it is possible to join a purlin and a bundle of huts.

  And the end surface of a wire is fixed to the joining board with which the outer shell part was equipped. Fixing is performed by a coupling tool and a holding unit that holds the coupling tool. The holding portion is formed of a through hole, a screw hole, a hook-like engagement structure, or the like according to the type of the coupler.

  The joining plate makes it possible to fix the end surface of the wire, and it does not have to be fixed to the joining plate. If part of the joining plate is exposed as described above, it can be left as it is or blindfolded. An appropriate member such as an adjuster or an adjuster can be fixed.

  Further, it is preferable that an inner connection part for connecting and fixing the joining plates to each other in the outer part is formed in the outer part. In this case, the joining plates are connected to each other by the inner connection part, and the form of the outer part is formed. In addition to being held, depending on the form of the internal connecting portion, it is possible to fix the coupler in a more stable and stable state.

  As described above, according to the present invention, since the outer portion is interposed between the end faces of the wire rod, the wire rod such as a column can be replaced, and the replacement work is easy.

An embodiment for carrying out the present invention will be described below with reference to the drawings.

Since the column base metal joint 11 is an installation type used by being placed on the grounding surface X, it is provided with an adjuster 61 for floating the joint metal 11 from the grounding surface X and leveling it. That is, screw holes 36 and 45 for screwing the male screw portions 61a of the adjusters 61 at equal intervals are formed at portions of the lower end bonding plate 32b and the lower partition wall portion 42 that are close to the four side surface bonding plates 32c. .

  Further, the upper end joining plate 32a and the upper partition wall 42 hold a bolt 51 as a coupling tool from below. Similarly, the bolts 51 as the couplers are also held in the through holes 33 of the side surface joining plates 32c. The four bases 23 as the wire 21 are fixed to the bolts 51 held by the side surface joining plates 32c by the columnar core member 52 and the drift pin 53. The core material 5 is made of metal having an internal thread 52a on one side in the length direction and an insertion hole 52b through which the drift pin 53 is inserted on the other side.

  The base 23 is joined by rotating the bolt 51 by bringing the base 23 with the core material 52 inserted and held close to the joint hardware 11, and screwing the core material 52 to the bolt 51 of the joint hardware 11. It can also join by inserting 23 in the core material 52, and fixing with the drift pin 53. FIG. Instead of the drift pin 53, a bolt and nut can be used.

  Then, as shown in FIG. 6, after the bases 23 are joined to the four sides of the joint hardware 11, the core material 52 is screwed onto the bolt 51 that protrudes upward from the upper end joining plate 32 a, so that the wire 21 is formed. The column member 24 is fixed.

  When the metal joint 11 is configured as described above and used for joining the column bases, the end surfaces 22 of the four bases 23 to be joined and the end surface 22 of the single pillar member 24 are the outline of the joint metal 11. It fixes in the state which contact | abutted to the joining board 32 which comprises the part 31. FIG. At this time, the side surface of the base 23 and the columnar member 24 and the end surface 22 are in surface contact with each other, and are not joined so as to be engaged with each other, but are joined so that the edges of the end surface 22 come into contact with each other. The joint hardware 11 is buried inside. For this reason, the wire 21 can be easily replaced, and an excellent building that can be used over a long period of time can be obtained.

  Moreover, the joining of the joining hardware 11, the base 23, and the pillar member 24 can be performed with a simple structure using the bolt 51, the core member 52, and the drift pin 53, and the work is simple.

Further, when fixing the plate member 71 and the reinforcing hardware 72, if necessary, as shown in FIG. 7A, the side joint plate 32c is processed with attachment holes 37 and 37 suitable for fixing. As shown in FIG. 7A, when the side surface joining plate 32c is moved backward to the inside corresponding to the thickness of the plate material 71 from the surface position of the base 23, the surface of the plate material 71 and the base 23 and It ’s good because it can be made flush.

  8, 9, and 10 are longitudinal cross-sectional views of the usage state of the columnar joint hardware 11 according to another example. Hereinafter, although these are demonstrated, the same code | symbol is attached | subjected about the site | part same or equivalent to the previous structure, and the detailed description is abbreviate | omitted.

  The metal joint 11 shown in FIG. 8 has the same configuration as described above, but has a structure in which a bolt 51 for joining the column member 24 is inserted and held from below the lower end joining plate 32b. The through holes 33 and 34 of the lower end joining plate 32b, the partition walls 42 and 42, and the upper end joining plate 32a may or may not have internal threads that allow the bolts 51 to be screwed, and even if they have internal threads. Further, it can be formed only in some of the through holes 33 and 44.

  In the figure, reference numeral 54 shown by an imaginary line is a nut, which keeps the bolt 51 firmly fixed.

  The metal joint 11 shown in FIG. 9 shows an example in which the structure of the internal connection portion 41 is different. That is, the internal connection portion 41 includes two partition wall portions 42 and 42 and a pipe-like columnar portion 43 that extends vertically through the partition walls 42 and 42 and directly couples the upper end joining plate 32a and the lower end joining plate 32b. A through hole 33 having a smaller diameter than the inner diameter of the columnar portion 43 is formed in the upper end joining plate 32a and the lower end joining plate 32b. The through-hole 33 may be either having a female screw or not. Although not shown in the drawing, the through hole 33 portion of the upper end joining plate 32a can be depressed to form a recess for receiving the nut.

  10 shows an example in which the metal joint 11 shown in FIG. 10 is fixed to an anchor bolt 55 provided on the foundation Y. In order to fix to the anchor bolt Z, it is preferable not to form female threads in the through holes 33 formed in the upper end joining plate 32a, the lower end joining plate 32b, and the partition walls 42 and 42. Further, in order to absorb the deviation / error of the position of the anchor bolt Z, the through hole 33 formed in the upper end joining position 32a and the lower end joining plate 32b is preferably a fool hole that allows the anchor bolt Z to be loosely fitted.

  In use, the foundation packing Z is disposed on the foundation Y, and then the through holes 33 and 44 of the metal fitting 11 are inserted and fixed to the anchor bolts 55 to join the base 23 and the column member 24. Repeat in order. When fixing the metal fitting 11, as indicated by phantom lines in FIG. 10, if the nuts 54 and 54 are fixed so as to contact the upper surface of the lower partition wall portion 42 and the lower surface of the upper partition wall portion 42, A firm fixed state is obtained.

(Joint hardware for beams)
FIG. 11 is a perspective view of the joining hardware 11 portion of the beam portion, and FIG. 12 is a longitudinal sectional view thereof. As shown in these drawings, the end face 22 of the wire 21 is joined to all six joining plates 32. Has been. The joint 11 for the beam is formed in the same manner as the joint shown in FIGS. 1, 2, and 3, and a bolt 51 as a coupler is held in the through hole 33 of each joining plate 32. ing.

  Unlike the column base 11, there is no need for the adjuster 61, so it is not necessary to form a screw hole 45 (see FIG. 4) for fixing the adjuster 61. Therefore, the metal joint 11 for the column base can be used.

  Since the basic configurations of the outer shell 31 and the inner connecting portion 41 are the same, the same or equivalent parts as those described above are denoted by the same reference numerals and detailed description thereof is omitted.

  First, as shown in FIG. 13, such a joint 11 for a beam portion uses a bolt 51 and a core material 52, and a lower end joining plate 32 b on an end surface 22 of an upper end of a column member 24 as a wire 21. Are joined so that they are in surface contact. Then, a horizontal member such as a beam member 25 is joined to the four side joining plates 32c, and finally, another pillar member 24 is joined onto the upper end joining plate 32a.

  When the joint 11 for the beam is used for a one-story building or when used for the upper end portion of a multi-story building, the upper end joining plate 32a does not hold the bolt 51. If the suspension bolt 62 as shown in FIG. 14 is attached, it is convenient for suspension performed in the case of a unit house. In addition, even if the bolt 51 is held on the upper end joining plate 32a, a member that performs the same function as the suspension bolt 62 can be attached.

  Further, instead of the two bolts 51 respectively held on the lower end joining plate 32b and the upper end joining plate 32a, a single bolt 51 penetrating vertically as shown in FIG. 15 may be used. In this case, since it is not necessary to tighten the bolt 51 inside the outer portion 31, the columnar portion 43 as the internal connecting portion 41 can be provided from the upper end joining plate 32a to the lower end joining plate 32b. The partition walls 42 are connected to the four side surface bonding plates 32 c from the outer peripheral surface of the columnar portion 43.

The metal plate 11 is fixed in a state of abutting against the joining plates 32 constituting the outer portion 31 of the metal object 11. At this time, the side surfaces of the column members 24, 24 and the beam members 25 and the end surface 22 are in surface contact with each other, and are not in a joined state in which the end surfaces 22 come into contact with each other. The joint hardware 11 is buried in the space surrounded by. For this reason, the wire 21 can be easily replaced, and an excellent building that can be used over a long period of time can be obtained.

  Moreover, the joining of the joining hardware 11, the column members 24, 24, and the beam members 25 can be performed with a simple structure of the bolt 51, the core member 52, and the drift pin 53, and the operation is simple. In addition, less processing is required for the column members 24 and 24 and the beam members 25. For this reason, the firm fixed state which surfaces contact | connected closely is obtained.

  Moreover, since the internal connection part 41 is formed in the inner side of the outer part 31, it can be set as the firm structure which can endure the load of length and breadth, and a sturdy building can be obtained.

  And the presence of this internal connection part 41 will hold | maintain the volt | bolt 51 which fixes the column material 24 in the through-holes 33 and 44 of two members, and the fixed state of the volt | bolt 51 is highly stable. It will be solid.

  FIG. 16 shows another example of the fixing structure of the beam member 25 to one side joining plate 32c of the four side joining plates 32c... In this case, an internal thread 33a is formed in the through hole 33 of the side surface joining plate 32c in order to fix the beam receiving member 56. In this way, the last beam member 25 of the beam members 25 connected in four directions can be easily joined and removed, as compared with the case where the bolt 51 and the core member 52 are used.

  In addition to this, as shown in FIG. 17, for example, a through hole 33 as a holding portion of one side joining plate 32 c is formed in a reverse snowball shape having an outer diameter on the upper side, You may make it hook the head of the engaging member 57 protruded from the end surface by the thickness of the side surface joining plate 32c.

  FIG. 18 shows an example in which the joint 11 for a beam part is used not only for joining one beam member but also for joining a special beam panel 26 having two beam members vertically in parallel. ing. In the figure, 26a is an upper beam material as the wire material 21, 26b is a lower beam material as the wire material 21, 26c is a bundle member, and 26d is a load-bearing panel. The metal joint 11 is the same as that shown in FIG.

  That is, after joining the first joining hardware 11 to the upper end of the pillar material 24, the auxiliary pillar material 27 as the wire 21 is joined on the first joining hardware 11. After joining the second joining hardware 11 on the auxiliary pillar material 27, the upper beam material 26 a of the beam panel 26 is connected to the side surface joining plate 32 c of each joining hardware 11 using the bolt 51 and the core material 52. The end face 22 of the lower beam member 26c is joined.
