Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to connection reinforcing hardware such as columns and beams in a conventional frame construction method.

[0002]

[Prior art]

 Conventional connecting hardware such as columns and beams are as follows. About existing connection hardware for pillars and horizontal members When connecting pipe columns, horizontal members, and columns and horizontal members, complicated connections are made, and these are individually reinforced by joining, as seen in bladed bolts and banded materials. ing. 2. On the other hand, in recent years, several types of metal joints have been devised in accordance with the rationalization of the conventional construction method, but all of them have been devised to simplify joint processing of pillars and horizontal members and strengthen joints. It is characterized by a large load burden. 3. In addition, the cross-sectional area is cut (reduced) by a precut that engages with the connecting hardware at the end of the beam, and most of the pillars are connected to the pillars with bolts or the like, and the ends do not rest on the pillars. In other words, the load is transmitted from the beam to the column via the mounting bolt, pin connection hardware, and column mounting bolt.

[0003]

[Problems to be solved by the invention]

 The technology described in the prior art has the following problems. 1. When the horizontal member is directly supported by a through column, the column is damaged at the joint at the joint and the strength of the column is reduced due to the cross-sectional defect. In addition, if the horizontal members are not directly supported by columns but supported by beam receiving hardware, long-term safety at the joint is lacked due to the strength of the hardware. 2. Recently devised hardware relies solely on hardware, and there are no parts that receive beams.The absolute value of the supporting force is small, and it is not suitable for large loads. There are many things that are not suitable for building a large-scale space. 3. Since the load is directly applied to the hardware and bolts, the pillars and horizontal members are entangled, and depending on the members, they are likely to be deformed or the wooden part to be split. 4. Since the supporting points of the horizontal members and the pillars are interposed by metal, thinning due to drying of the wood causes loosening and poor safety under horizontal force (particularly during an earthquake). 5. Until about ten years ago, such hardware was almost nonexistent. In other words, there has been a conventional structure in which the purpose of connecting pillars, beams, and the connection of columns and beams is solely present. However, the existence of metal that connects all these members at one contact point at the same time has been increasing. Not even found in years. 6. This is why it did not exist. However, when the members (columns and beams) were connected simultaneously using the column as a supporting point, chipping (cross-sectional loss) into the column was enormous in the conventional joint processing technology. Because of this, the strength of the column (buckling strength) and the strength of the fulcrum (support point) of the beam are greatly reduced, and it is judged that it is dangerous. It is customary to carry out the joint (method of taking out the beam 150 m / m inside and outside from the column fulcrum and joining the beam). The present invention has been made in view of such problems of the prior art, and has as its object to provide what can be performed as follows. It is a reinforcing metal that can connect these members at the same point of contact at the same time at the joint of the columns, beams, and columns and beams.

【Example】

 Referring to FIG. 5, the upper front connecting plate 2, the upper rear connecting plate 3, the lower left connecting plate 4, and the lower right connecting plate 5 are as follows. Was preferred. In addition, since each of the above-mentioned connecting plates alone is also the same in dimensions, a description will be given of the upper and lower connecting plates 2 as an example. B. Width of plate body 2A to about 200 mm b. Height of plate body 2A to about 300 mm c. Width c of central portion 2B to about 80 mm d. E. Width d of left portion 2C to about 60 mm e.

Depth of depth 2A3 on the right 2A3 ~ about 150mm In order to perform the construction procedure smoothly, it is necessary that the parts to be attached to the upper part of the first floor and the lower part of the second floor are not separated and integrated. Become. If they are integrated, it is difficult to use, and there are many disadvantages and the cost increases.

[0016]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. 1. Since four pieces of the same shape and the same size are used as one set and used in combination, the production of connecting reinforcing hardware such as columns and beams can be mass-produced and the cost is low. In addition, the workability is improved because the work is performed by combining two of them attached according to the work procedure. That is, the upper front connecting plate 2, the upper rear connecting plate 3, the lower left connecting plate 4, and the lower right connecting plate 5 are not integrated, but are separated. The first reason is that the same shape can be used for all parts by combining them, and the production of connecting reinforcing hardware such as columns and beams can be mass-produced and cost can be reduced. In addition, the efficiency of the inventory space, the efficiency of the transportation, and the like can be improved. Furthermore, since the structure and combination of connecting reinforcements such as columns and beams are simple, the method of processing the cuts (connections) at the ends (joints) of each member can be unified, and special processing is required for simple processing. No machine is required, and the precut production rate can be improved. As a result, the number of processing man-hours and assembly man-hours can be significantly reduced. In addition, it is possible to cope with the correction (correction, adjustment) at the time of assembling by utilizing the fact that it moves slightly during assembling. 2. The upper front connecting plate 2, the upper rear connecting plate 3, the lower left connecting plate 4, and the lower right connecting plate 5 are engaged with each other in a cross shape, and the steel plate increases the contact surface area. Thus, it is possible to enhance the mutual coupling strength of the columns. In other words, the reason for meshing with the cross is the same as the principle of winding steel plate to reinforce the column base of an elevated road that has just collapsed due to the Great Hanshin Earthquake. This is because it is possible to enhance the mutual coupling strength of the above.

[0017] 3. The column is pre-cut so that the ends of the connecting reinforcements such as columns and beams are inserted into the columns, so that the ends of the beams are securely placed on the columns, and the load is transmitted directly from the beams to the columns. High safety. 4. The openings of the horizontal members 8, 9, 10, and 11 such as beams are in contact with the columns 6 and 7 and the hardware over the entire area thereof through the connecting reinforcing hardware such as the columns and beams of the present invention. Further, these horizontal members such as beams are connected to sleeve portions formed on connection reinforcing hardware such as columns and beams, ie, for example, the front portion 4C of the lower left connecting plate 4 and the lower right connecting portion. The plate 5 is sandwiched between the front portions 5C. In addition, the horizontal members such as beams and the bolt penetration holes formed in the above-mentioned sleeve portion, for example, the bolt penetration holes 4C1 formed in the front part 4C of the lower left connecting plate unit 4 and the lower right connecting plate, for example. By connecting the bolt and the nut using the bolt penetration hole 5C1 formed in the front part 5C of the unit 5, the frictional force is obtained by the torque (tightening force) by the bolt and the nut, and the end of the cross member is obtained. The parts will be joined and held in the largest area. In this case, no processing is required for the opening of the horizontal member. Also, by driving the pin using the pin penetrating hole 4B21 and the pin penetrating hole 5B21 formed in the above-mentioned sleeve portion, the pin sinks into the wood and produces the same frictional force and has the same effect. Become. 5. Another reason why the strength can be maintained is that the entire cross section of the end of the beam is in contact with the column, and in addition to maintaining the strength in the vertical and vertical directions, the horizontal strength is also improved by changing the point from point to surface. It also has an effect on retention. As described above, the present invention is useful because it eliminates the drawbacks of the conventional splicing, and at the same time increases safety by increasing the joint strength and rationalizes the wooden structure.
