Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the construction of the joint parts between the upper and lower ends of columns and horizontal members such as girder beams, which are used in the conventional framework construction method of wooden buildings and other structures. This invention aims to simplify the joint, promote the rationalization of the joint, shorten and simplify the construction period, and relates to a joint used in the joint and its joining method.

[Prior art and its problems] The frame construction method consists of connecting columns, which are structural members, with horizontal members such as foundations or girders. It is composed of a joint tenon 2 and a tenon hole 3, which are joined together.In other words, the dimensions of each structural material are determined by an engineer (carpenter). In addition, the foundation and girders are also processed and joined together.The above joining method has been passed down from ancient times and is a unique Japanese method.This method is based on advanced technology and rational combinations. However, due to increasing demand and a shortage of engineers due to the aging of engineers, it is desired to save labor in both structural material processing and on-site construction, so prefabricated panel construction methods, 2 × 4 construction methods, etc. are used as labor-saving methods. Each of these methods has its advantages and disadvantages, and each method requires greater labor savings and shorter construction time than any other method.However, with the exception of the frame construction method, it is difficult to freely design the floor plan and design of free openings, which is a disadvantage. Therefore, it is necessary to develop a framework construction method that allows for free design, which simplifies the construction even a little, does not require sophisticated joint work, and shortens the construction period, and which is also powerful.

[Problems to be Solved by the Invention] To explain the joint processing in the conventional frame construction method, first of all, marking the pillars requires work, and it is necessary to rotate the pillars four times just to mark one end of the pillars. The marking of the small tenon 2 requires a minimum of 5 turns, which means 10 turns at both ends, and the same goes for the marking of the opposite horizontal member. It is necessary to mark holes, etc.; horizontal members have a large volume and require a lot of effort to handle; each marked material must be processed accurately based on the markings. Nari marking requires more work. In order to save labor in this processing, mass production has been carried out in some parts by extensive mechanization and automation through computer control, but it is only a part of the overall process, and the method is still traditional Shiguchi, but The main purpose is to save labor, and only some contractors can use it, and general engineers are also using all kinds of gadgets to save labor, but it seems that labor-saving has reached its limit. For these reasons, it is necessary to fundamentally review the joining method and develop one that can be easily used by general engineers and can be processed reliably and accurately. In addition, the present invention aims to develop and provide a connecting tool and a connecting method thereof that have a stronger connection in terms of strength, save labor, shorten the construction period, and enable inexpensive processing and assembly.

[Means for solving the problem] As explained in the previous section, the main purpose is to make it easy for general engineers to use and save labor.Currently, general engineers are using the conventional shikkuchi method with the frame construction method. We are working to save as much labor as possible by using small processing machines, but the current situation is that labor saving has reached its limit.
In order to overcome the current situation as described above, it is necessary to fundamentally reconsider the method of joint processing.The edges of the pillars are only cut to a specified length, and no joint processing is performed at all.The only tool used is a drill for digging ropes. The purpose of this project is to develop a connecting method and a connecting tool that can be connected simply by inserting the holes by using a separately mass-produced connecting tool, with drilling holes made by et al. as a work only.

[Function] As explained in the previous section, the joining method is to simply cut the columns to length, and the machining involves digging holes suitable for inserting connectors into the upper and lower edges of the columns, and then building the horizontal structure. This completes the drilling and processing of each piece of wood in a similar and contrasting manner. The connector is rod-shaped,
It is a hollow rod-shaped connector that is cut to the length required for vertical installation, and both ends are shaved off and manufactured separately to facilitate initial insertion.This connector is easily available as a commercially available product. Make it. At the site, the pillars are first erected by driving connectors into the top and bottom of the pillars and inserting the pillars into the holes in the foundation.The pillars are temporarily secured to prevent them from falling, and then the horizontal structure is suspended from a wrecker. Fix the material to the connecting tool at the top of the column and complete the connection.
As described above, the assembly and connection are the same as before. The shapes of the connectors are various, such as round bars, square bars, polygonal bars, those with irregularities on the outer circumferential surface, and those with inverted protrusions engraved in the direction of the earth. A wide variety of shapes such as hollow ones can be created, and materials such as metal plastics and ceramics can also be used. When inserting a connector into a hole that has been dug, care must be taken to avoid cracking or other damage to the pillars, etc. by punching the connector into the hole, which is especially thicker than the hole in order to increase pull-out friction. This connector must be able to save labor in machining such as joints, be mass-produced, and always be available at a low price, and must be profitable at a lower unit price than the joint process.

[Example 1] The method of digging a trench with a connecting device can be fully understood by using a gymnastic drill, an electric drill, etc., which are currently used by general engineers. The pillars are cut to a predetermined size, and hole positions are marked in 2 to 3 places as needed depending on the direction of the base and the horizontal member, and the holes are drilled at a predetermined depth. With this, the machining is completed and assembly begins on site, but it is necessary to insert connectors above and below the pillars in advance.
If you set up the horizontal members first, the connectors will protrude from the sides, which will impede and unreasonable handling, so it is better to do it at the columns first. Also when handling columns, connect them. Since the tool protrudes from the edge, it can be handled by holding the connecting tool, which is convenient, and can also be used to prevent damage to the edge. The pillars with the connectors installed are erected on site, and after being temporarily fixed, they are suspended from 7 etc. to fix the horizontal members and complete the connection.In the vertical direction, the columns and horizontal members are It is possible to complete a strong joint by reinforcing it with plates.

[Example 2] We have explained various things about assembly, etc., but in this section, we will explain the connector itself.The connector should be replaced with the conventional tenons at the top and bottom of the column, and it can be used for accurate positioning and fixing the direction of the column. The main purpose is to do this, and that purpose can be achieved if the column itself has the strength to support the load of the horizontal members.The position of the column is determined by the position of the hole to be dug, but it is important to fix the direction. If there is one pillar in the center, the pillar will rotate, so it is necessary to take measures to prevent it from rotating.To prevent it, it is necessary to hammer in nails or take other measures. be. If the hole is larger than the connector inserted into the hole and there is a gap, the fixation of the position will become unstable and it cannot be used for that purpose, so a suitable sized moat cable is required.Another method is to use a square type 8, polygonal type 9, etc. may be used. As shown in Figures 5 and 6, the corners of the connector are forcibly driven into the round hole 7, which increases the frictional force that resists pulling out and ensures stable fixation. Ru. Next, two types of connectors will be explained as an example.
As shown in the figure, this method uses commercially available deformed reinforcing bars, which are cut to the specified dimensions and the top and bottom ends are shaved off to facilitate initial insertion. Deformed reinforcing bars have unevenness on the outer periphery, so there is no frictional force. The length of the connector is large, the unit price is low, and it is worth using.Next, as shown in Figure 8, the length of the connector is divided into upper and lower parts, and inverted protrusions are engraved on the outer circumferential surface of each in the opposite direction, so that there is less resistance to insertion. This is a connector that has been processed to have a high resistance against pulling out. Although it is somewhat burdensome to process, it has a large force against pulling out, so it has a large binding force and is effective.

[Effects of the invention] There is a shortage of engineers due to the increasing demand for labor saving through mechanization of factory production of prefabricated panel construction methods, 2 x 4 construction methods, and joint joint processing of conventional frame construction methods, and the shortage of engineers that will occur in the future. In order to solve the current shortage of engineers due to the aging of general engineers, it is necessary to further promote labor-saving measures. However, with construction methods other than the frame construction method, it is impossible to freely design floor plans and openings, etc. However, as explained above, there is a limit to the labor saving of joint processing, and the current limit has been reached.In order to overcome this current situation, we will fundamentally reform the joint structure. It is necessary to overcome the current situation by developing a connecting tool and a joining method that can make a stronger connection without reducing strength.The only processing tool that can be used is an electric drill, and the connecting tool is cheaper than tenon processing. In addition, it is essential that it is always available as a commercial product, that all engineers can use it, and that the construction work can be completed accurately and easily.As explained above, it must be simple. This invention is provided in order to promote labor saving by inventing and developing an inexpensive connecting device and connecting method.This connecting method and connecting device can also be used to connect other similar bundle columns, etc. It goes without saying that they can be used as such.
