Description

  The present invention relates to a fitting that is attached as a reinforcement for connection of upper and lower floor pipe columns and mutual connection of trunk differences.

  A plurality of through-holes for inserting screws (screw nails) are provided symmetrically with each other on both sides of the longitudinal direction of the metallic main plate made of short metal, for example, passing between upper and lower pipe columns. There is a structure in which the connection between the tube columns is reinforced by screws (Non-Patent Document 1).

  The conventional example adopts a structure in which the surface of the shaft assembly is overlapped and fastened with screws (some bolts and nuts are tightened, but here is another theory), so that the screw head protrudes from the surface of the fitting metal, It may interfere with the next work such as attaching wall panels.

  For this reason, in order to assemble the head so as not to protrude from the main plate, embossing is performed to form a recessed portion having a diameter commensurate with the diameter of the head, and screw screw legs are provided on the bottom wall portion of the recessed portion. A through-hole to be inserted is provided so that the head is accommodated in the recessed portion, and the main plate surface and the head surface of the screw head are at least the same surface (Patent Document 1). .

The position in the short direction of the fitting for a wooden building is shifted from the position in the short direction of the fitting for the wooden building of the through hole portion of the outermost row and the through hole portion of the middle row. First feature.
Further, the fitting for a wooden building according to the present invention comprises a plurality of through holes for inserting screws on both sides in the longitudinal direction of the short metal main plate, and each through hole is extruded. A recessed portion that is molded to engage the head portion of the screw and an insertion hole through which the screw leg of the screw provided at the center of the recessed portion is inserted, and the insertion hole is a cylinder protruding from the recessed portion. It is a fitting for a wooden building, and each of the through holes is provided in three rows at predetermined intervals on the left and right sides of the central portion in the longitudinal direction of the wooden building. The distance in the longitudinal direction of the fittings for wooden buildings between the through holes in the middle row and the through holes in the middle row is for the wooden building between the through holes in the outermost row and the through holes in the middle row. It is smaller than the interval in the longitudinal direction of the joint metal fitting, and the innermost through hole portion has the wooden building joint. Position in the transverse direction of the hand hardware, the outermost column through hole section and the intermediate rows hole portion the wooden building fittings hardware position and deviation that the second and the lateral direction of the Features.

  According to the present invention, the screw insertion hole is constituted by a protruding cylinder protruding from the recessed portion (accommodating the screw head), so that the protruding cylinder pressed by the screw head during construction is made of wood. Without being deformed in the material, it is securely inserted, it can absorb the thinness due to the change of the wood material when sandwiched and prevent the screws from loosening, and as a reinforcing material, maintain the connection state between the wood, It is possible to obtain the connection state of the wood material corresponding to the temporal change of the wood material.

  The drawings show an embodiment of a fitting for a wooden building according to the present invention, and the fitting A for a wooden building A is formed on both sides in the longitudinal direction of the metal main plate 1 having a short shape, and between the two sides. Provided with a through-hole portion 2,... Symmetrically (can be used regardless of directionality by providing it symmetrically), and in the central portion between the both sides, is formed into a long and narrow triangular tongue. On the surface of one woody material (for example, one beam) which is formed by providing a temporary fixing claw 10a formed by bending a piece at an intermediate portion and connecting the through-hole portions 2,... , The other through-hole portions 2,... Are superimposed on the surface of the other woody material (for example, the other beam), and screws (screws) are inserted using the insertion holes 202 provided in the through-hole portion 2. Nail) n is inserted into a wood material and assembled to connect both wood materials.

  The through-hole portion 2 is provided by opening the center of the recessed wall 201a formed by extrusion molding (embossing) and the bottom wall 201a of the recessed wall 201, and the insertion hole 202 communicating with the recessed portion 201 is provided. The insertion hole 202 of the through-hole portion 2 is configured by surrounding the center portion of the bottom wall 201a with a protruding cylinder 202a that is continuously formed by burring and protruding into a cylindrical shape.

Then, as shown in FIG. 9, for example, when connecting a pair of beam members b and b along the longitudinal direction, the joint metal A is brought into contact with the end surfaces of the beam members b and b at the center in the longitudinal direction. The temporary claw 10a is driven into the beam material b so as to be overlapped with the portion, and is temporarily fixed, and the screw holes nc of the screws n are sequentially inserted into the through-hole portions 2 of the joint metal A, which are temporarily fixed, by screwing with a tool. When screwed into the beam member b, the head na of the screw n is inserted into the recessed portion 201 of the through hole 2, and the round root nb is inserted into the insertion hole 202. The head na touches and presses the bottom wall 201a of the recessed portion 201, and the pressed bottom wall 201a is inserted into the beam material b and sinks, and at the same time, protrudes from the outer surface of the bottom wall 201a. The protruding cylinder 202a is inserted into the beam material b as the screw n advances. When the main plate 1 is in close contact with the beam material b, the forward movement of the screw n is restricted, and the screwing operation of the screw n is finished. Thus, the joint metal A is assembled by combining the screw n with each through-hole portion 2. By connecting and fixing to the beam members b and b, the connection work of the beam members b and b using the hardware A is completed.

  Note that when the protruding cylinder 202a is embedded in the beam material, that is, the wood material with screwing of the screw n, the protruding cylinder 202a moves (guided) along the leg rod nc of the screw n, so that its deformation is prevented.

  The projecting cylinder 202a that is pressed by the screw head na during the tightening operation and is embedded in the beam material is fixed to the beam material b. Therefore, even if the beam materials b and b through the joint metal A are thinned, Following the beam material b, it is possible to relatively prevent the occurrence of a gap (separation between the two) between the hardware A and the beam material b.

  Further, the insertion hole 202 of the embodiment is formed by reducing the area to be punched and expanding to the hole diameter through which the screw n passes by burring, and by reducing the area to be punched, the sectional area of the hardware itself is increased. It is difficult to break the hardware itself in the insertion hole 202 when a tensile force is applied to A, and further, by providing the protruding cylinder 202a, the area into the beam material b, that is, the wood is increased, The gap between the beam material b and the hardware A can be reduced.
