[Industrial applications]

 The present invention relates to a building screw fastening device for connecting building members such as columns and beams.

[0002]

[Prior art]

 Conventionally, a joining means such as a groove, a tenon and a mortise is used for joining building members such as columns and beams, and a joining tool called a hago board is used to make the joining more reliable. To be The hago plate is a threaded rod to which a locking plate is welded.For example, when beams and beams are to be joined with a dovetail groove, make a hole in the beam on the dovetail groove sideways and insert the screw rod into the hole. Then, the locking plate is attached to the side surface of the beam on the dovetail side and fixed with nails, etc., and the nuts are screwed into the threaded rod that penetrates the beam on the dovetail groove sideways to tighten the beams. When joining a beam to a column, make a hole in the column horizontally, insert a screw rod into the hole, attach a locking plate to the side of the beam and fix it with nails, etc. The nuts are screwed onto and the beams and columns are tightened together.

【Example】

Next, an embodiment of a building screw fastening device according to the present invention will be described with reference to the drawings. Example 1 In FIGS. 5 to 6, reference numerals 1 and 2 denote beams made of wood, which are building members of buildings. The dovetail 3 is formed at the end of one beam 1, the dovetail groove 4 is formed in the middle of the other beam 2, and the dovetail 3 is inserted into the groove 4 so that one beam 1 is formed. It is joined to the other beam 2 so as not to slip out.

A building screw tightening device 36 as shown in FIGS. 1 to 3 is attached to the joining portion. This building screw tightening device 36 includes a threaded rod 5 having threaded portions 5a and 5b at both ends, a guide tube 37 into which the threaded rod 5 is slidably inserted, and the guide tube 37 by welding or the like. It has a metal locking plate 8 to be fixed. The guide cylinder 37 is fixed to one end of the locking plate 8, and the screw rod 5 extends from above the locking plate 8 to a position farther than its tip. Reference numeral 38 indicates welded meat. A nut 39, which is a flange, is screwed onto the rear end of the screw portion 5b of the screw rod 5 located on the locking plate 8, and the coil-shaped spring washer 10 is interposed between the nut 39 and the guide cylinder 37. Has been done. As shown in FIG. 4, the coiled spring washer 10 is formed by winding a linear spring material having a quadrangular cross section a plurality of times, and both ends 10a and 10b of the coiled spring washer 10 are in a compressed state. It is thinly formed to have a cylindrical shape. Both ends 10a and 10b are in contact with adjacent winding portions so that they can be easily inserted between the guide tube 37 and the nut 39. The cross section of the linear spring material is not limited to a quadrangle, but may be another shape such as a circle. Another nut 6 is screwed into the threaded portion 5a of the threaded rod 5 projecting forward from above the locking plate 8. A washer 11 is applied to the nut 6 if necessary. The locking plate 8 extends further rearward than the rear end of the screw rod 5, and a hole 40 for inserting a nail and a hole 41 for inserting a bolt 9 are provided therein.

In order to increase the joining force between the beams 1 and 2, the building screw tightening device 36 is mounted as shown in FIGS. 5 to 7. That is, a hole 7 is formed in the beam 2 on the dovetail groove sideways, and the screw rod 5 is inserted into the hole 7. Further, the locking plate 8 is applied to the side surface of the beam 1 on the side where the locking plate 8 is present, and is locked with bolts 9 and nails. The threaded portion 5a at the other end of the threaded rod 5 extends laterally through the beam 2 on the groove side, and the nut 6 is screwed to the portion protruding from the beam 2 via the washer 11.

By tightening the nut 6, the screw rod 5 is pulled to the left in FIG. 2, the coil-shaped spring washer 10 is compressed between the guide tube 37 and the nut 39 at the rear part, and elastic as shown in FIG. Deform. Therefore, the engaging force between the dovetail 3 and the dovetail groove 4 is increased, and the beams 1 and 2 are fastened together. The amount of compressive deformation of the coil-shaped spring washer 10 is the same as or larger than the amount of contraction of the beams 1 and 2 made of building members due to aged deformation, and is, for example, about 3 mm to 5 mm. As a result, even if the beams 1 and 2 contract due to aged deformation, the coil spring washers 10 elastically return according to the contraction, so that the tightening force by the screw rod 5 and the nut 6 is maintained. Therefore, the gap between the dovetail 3 and the dovetail groove 4 is also eliminated, the fastening state of the beams 1 and 2 is maintained, and the strength of the building is maintained.

The locking plate 8 can be locked to the beam 1 by a nail, but as shown in FIGS. 5 to 7, a hole 13 is made in the beam 1 and a bolt 9 is passed through the hole 13. The nut 14 may be used for tightening. An elastic washer 15 having rubber-like elasticity and a metal washer 16 are interposed between the nut 14 and the recessed portion 34 of the beam 1, and the amount of shrinkage due to the drying or the like of the beam 1 is expected to be the same as the amount of shrinkage. If the elastic washer 15 is compressed to some extent or more, loosening and rattling of the locking plate 8 can be prevented.

It is also possible to mount the threaded rod 5 on the beam 1 by providing a hook piece on the threaded rod 5 instead of the locking plate 8 and driving it into the beam 1. Example 2 In FIGS. 8 and 9, reference numerals 17 and 18 denote beams and columns made of wood, which are building members of buildings, respectively. A tenon 19 is formed at the end of the beam 17, a tenon (not shown) is formed in the middle of the pillar 18, and the beam 17 is joined to the pillar 18 by inserting the tenon 19 into the tenon. Has been done.

In order to increase the joint force between the beam 17 and the pillar 18, a construction screw fastening device 36 similar to that in the first embodiment is attached to this joint portion. That is, a hole 22 is formed in the pillar 18 in the lateral direction, and the screw rod 5 is inserted into the hole 22. Then, the locking plate 8 is applied to the side surface of the beam 17, and is locked by the nail 24 or the like. The threaded portion 5a of the threaded rod 5 penetrates the column 18 in the lateral direction, the coiled spring washer 10 and the metal washer 11 are sequentially inserted into the penetrated portion, and the nut 6 is finally screwed.

A recess 27 for accommodating the coil-shaped spring washer 10 or the like is provided at a position of the pillar 18 to which the coil-shaped spring washer 10 or the like is applied. The concave portion 27 can be omitted.

When the nut 6 screwed into the screw portion 5a is turned in the tightening direction, the engaging force between the tenon 19 and the mortise hole is increased, and the beam 17 and the pillar 18 are tightened. At the time of tightening, the coil-shaped spring washer 10 is compressed and elastically deformed between the metal washer 11 and the bottom of the recess 27, but the amount of compression is about the same as in the first embodiment. As a result, even if the beam 17 or the pillar 18 contracts due to drying or the like, the coiled spring washer 10 elastically returns according to the contraction amount, so that the tightening force by the screw rod 5 and the nut 6 is maintained. Therefore, the gap between the tenon 19 and the mortise is also eliminated, the fastening state between the beam 17 and the column 18 is maintained, and the strength of the building is maintained.

The locking plate 8 can be fixed to the beam 17 using bolts, nuts, coil spring washers, and metal washers in the same manner as shown in FIGS. 1 and 2 in addition to the nail 24. .
