Description

In the present invention, for example, one of earthquake-resistant hardware used for a direct earthquake of a wooden building frame construction method, anchor bolts 5 and attracting hardware 2 embedded in concrete 6 are used for pillars 8, and base-bound metal 1 and The brace 3 with the turnbuckle 10 and the pulling flat metal fitting 4 equivalent to the Ministry of Construction Notification No. 1460 builds the bearing wall to make the house earthquake resistant class 3 (1.5 times the force of the earthquake that occurs once every several hundred years) In contrast, a housing structure having a wall insulation material thickness of 100 mm is possible.

Issuance of “How to use wooden fittings for wooden houses” Japan Housing and Wood Technology Center, date of issue June 2001 Joints or joints, which are the main structural strength of wooden buildings, are announced by the Ministry of Construction in 2000 The above-mentioned hardware standards that require mounting and use of wooden fittings that correspond to No. 1460 must be strictly inspected as Z-mark hardware approved by the Japan Housing and Wood Technology Center. Received and sold to the market. However, the brace material is only the joint hardware corresponding to the wood.

"Law on Promotion of Ensuring Quality of Essentials and Housing" Revised 2001 issued Better Living Foundation, issued on August 24, 2001 A law on promotion of ensuring quality of houses was promulgated on June 23, 1999, Notification Japan housing performance display standards and evaluation standards came into effect in April 2002. Based on this standard, display items include 1-1 earthquake-resistant grade (preventing collapse of structural enclosure) 1-2 earthquake-resistant grade (preventing damage to structural enclosure) 1-3 wind-resistant grade (preventing collapse and prevention of structural enclosure) ) 1-4 Snow resistance rating (Preventing collapse and prevention of structural frame) 5-1 Energy saving measures, etc. In order to improve the grade, a different joint structure is required.

[Patent Document 1] JP 2003-176541 A Provided is an anchor guide that can easily and accurately position and guide an anchor bolt embedded in a foundation without a scale when performing foundation work, and that can biodestruct after use, and a method for manufacturing the anchor guide.

Patent application 2003-294240 Date of submission: August 18, 2003 A method of manufacturing a slat plate joint and a manufacturing method for reducing cross-sectional defects from 16 millivolts of the squeeze hardware to the wooden house frame joint.

Article 42 of the Building Standards Law Enforcement Ordinance and Notification No. 1460 are forcing two types of installation work for 12 mm anchor bolts and 16 mm anchor bolts 5 on wooden house foundations.

Since 12mm anchor bolts are embedded in large numbers, they are often embedded (rice planting) immediately after the concrete 6 is placed.

According to Notification No. 1460, installation of 16mm anchor bolts was required from 10 to 20 on the foundation of a traditional wooden house, but since it takes more than one day for the installation of three craftsmen, There are still few sites to bury and it is a violation of the law.

  Furthermore, if the number of attracted hardware is small, it will be difficult to make the floor slope regulated by the Ministry of Construction Notification No. 1653 in 2000 to be less than 3/1000.

A wooden brace of 90 mm x 45 mm is placed on the outer wall, and a heat insulating material of 30 mm or more can be put in place, except for attaching a heat insulating material to the pillar 8.

It has been verified in subsequent experiments that wooden braces break at an acceleration of 800 gal or more during the Hanshin-Awaji earthquake due to their low viscosity.

The said subject which concerns on this invention is eliminated by the junction structure of the following housing member.

The anchor bolt (5) fixed to the concrete foundation (6) fixes the column attracting metal (2) and the base metal fitting (1) to the base (7). A structure for joining house members, which is shaped like an inverted shape, with the horizontal part fastened to the anchor bolt (5) and the brace (3) fastened to the rising part.

  If one side of the brace 3 with the turnbuckle 10 is joined to the base fastening hardware 1 and the other is at the joint, the pulling flat hardware 4 equivalent to the Ministry of Construction Notification No. 1460 is attached to the upper column Secure with screws 11 etc. A joint structure for housing members, in which a brace with turnbuckle (3) is attached in an X shape in the same way to form a strong earthquake-resistant wall.

In a wooden house, pull the flat metal fitting 4 equivalent to the Ministry of Construction Notification No. 1460 of the adjacent column base (2nd floor) from the anchor bolt 5 of the foundation part 6 with the brace 3 with the turnbuckle 10, and the upper floor ( 3rd floor) Pulling metal plate 4 equivalent to the Ministry of Construction Notification No. 1460 is pulled by the brace 3 with a turnbuckle, and is attached to the horizontal brace 9 on the top floor. Pulling 4 with the stiffener 3 with a turnbuckle means that the cross section of the pillar 8 and the side brace material 9 is less when compared to the penetration work with the 16 mm diameter bolt of the horizontal side material 9 in Ministry of Construction Notification No. 1460, 1.2.3. Building a seismic wall through the floor is easy.

Tightening with the screw screw 11 etc. between the pulling flat metal plate 4 equivalent to the Ministry of Construction Notification No. 1460 and the head of the capital, etc. Perform after applying tensile force to the brace 3 with turnbuckle.

In the above work, it is easy to set the slope of the wall or pillar to Level 1 (less than 3/1000) according to the technical standards that should be used as reference for the settlement of the Ministry of Construction No. 1653 Housing Dispute.

  Hereinafter, an embodiment of a wooden house member joining structure according to the present invention will be described with reference to FIGS.

FIG. 1 is an example of a frame diagram of a three-story wooden outer wall. The present embodiment is a joint structure for housing members that is strong and simple and has a high work efficiency for craftsmen and can provide a cheap and safe building to society.

FIG. 2 is an example of a detailed connection diagram of the first-floor column base part. The 16mm diameter anchor bolt is made up of a screw that pulls the pillar 8 by the pulling hardware 2 by making the exposed part of the ground the whole screw, and further, the base fastening hardware 1, the brace material 3 and the turnbuckle Junction structure.

FIG. 3 is an example of a detailed connection diagram of the second floor and the third floor (intermediate floor). Housing where the flat metal plate 4 equivalent to the Ministry of Construction Notification No. 1460 is joined to the upper column base with screw screws etc., and then the column head is joined to the lower floor brace 3 after applying the tensile force with the turnbuckle 11 Joining structure of members.

FIG. 4 is an example of a detailed bonding diagram of the rooftop floor. Housing member joining structure in which a pulling flat metal plate 4 equivalent to the Ministry of Construction Notification No. 1460 is joined to a horizontal member with a screw screw 11 etc. and then applied to the head of the column after applying a tensile force in the same manner as above.

As described above, the joint structure for housing members according to the present invention has the following effects.

By placing two anchor bolts 5 on the outer column each, the attracting hardware 2 and the brace 3 are joined at the same position. Therefore, the bracing material 3 and the pulling metal plate 4 equivalent to the Ministry of Construction Notification No. 1460 can be manufactured at the factory by making them metal products, and the work time on site can be greatly reduced.

Also, factory production of components can improve seismic resistance and eliminate variations in on-site construction accuracy.

In addition, the joint structure of the housing members is metallized, so it is possible to improve the holding strength and supply wooden 3-story houses at a low price in a short construction period.

And strengthening the pull-out resistance of the pillars will lead to no damage from the direct earthquake.

Fig. 1 is an example of a frame diagram of a three-story wooden outer wall. FIG. 2 is an example of a detailed connection diagram of the first floor column base portion. FIG. 3 is an example of a detailed connection diagram of the second floor and the third floor (intermediate floor). FIG. 4 is an example of a detailed bonding diagram of the rooftop floor.
