Abstract

PURPOSE:To raise the efficiency of operations, shorten the period of construction, and reduce labor by eliminating the needs for marking and skilled workers by using a joint-reinforcing hardware made of a square thin steel plate both ends of which are thrust with two semicircular round bars and the central part is welded with steel plates. CONSTITUTION:Semicircular round bars 2 and 2' with projections 3, having a length of about 20cm and a diameter of about 12mm, are thrust through two holes 6 of a diameter of about 13mm which are formed in a square 4 - 6mm thick thin steel plate 1 with one side length of about 10cm, and the base plate 1 is welded to the central part of the bars 2 and 2'. To make up a joint- reinforcing metal. The bars 2 and 2' are then inserted into the holes 7 of a column 9, nails 8 are driven into the holes 5 to attach metals to the small holes of the column 9. The round metal bars 2 and 2' attached to the holes of the column 9 are inserted into the holes 7 of the base 10 and the beam 11 to fix the column 9 to the base 10 and the beam 11.

Description

[Detailed Description of the Invention] A. [Objective of the Invention] (Industrial Application Field) This invention provides a joint reinforcement for wooden buildings that can easily, accurately and firmly attach columns of wooden buildings. Regarding hardware.

(Prior art) In a wooden building, a pillar (9), a base (10), a pillar (9)
) and beams (11), and other pillars (9) are installed, and in a typical shikiguchi, Figure 4 (a) long hazo (b) short hazo etc.
Commonly used since ancient times, these shiguchi require very precise machining and require a high degree of skill to manufacture. Depending on the work, finishing must be done with saws, chisels, planes, hammers, etc., and precision is also required, resulting in poor workability (inefficient because strength depends on processing precision).

(Question 8 to be solved by the invention) Pillars (9) and foundations (9) are the main parts of wooden buildings.
10), the joints are the most important when installing the pillar (9) such as the pillar (9) and the beam (11). If the conventional method is used to form the strength of the house, the pillar (9) and the pillar (9) will be attached using a tenon or mortise in the base (lO) and beam (11) of the member. Marking is required during machining, and even if the marking is done with good accuracy, it will not be possible to finish the work accurately if the person who completes the processing does not have the skills. On the other hand, even if the person performing the processing is skilled, if the inking accuracy is poor, the result will be the same. In short, inking and machining require both advanced skills, but by using the metal fittings of this invention, complex inking and machining can be done. can be omitted; use a power saw to cut the lower edge of the column (9) vertically using an I2 round bar (2) (2)
The difference between the holes (7) and the hole (7) need only be drilled using an electric drill.
1) and the base (10), mark the insertion holes (7) for the round rods (2) (2'), and complete the drilling process using an electric drill. Therefore, with the simplification of work, it is expected that the unnecessary machining time and labor of experts will be reduced, and efficiency will be increased.
To provide joint reinforcing metal fittings for wooden buildings, which have no notches in the holes in the members such as ), thereby reducing the decrease in the strength of the members and making it possible to firmly and stably join these members. It is an object of the present invention to do so.

[Structure of the invention] (One step to solve the problem) In order to achieve this object, the hardware of this invention has the following structure. That is, 4 knees to 6 m as shown in Figure 1.
The base plate (1) is a square thin steel plate with a diameter of about 1.5 m, and the through holes (6) of the round bars (2) (2') are placed on the center line of the base plate (1).
A semi-spherical shape (4) is inserted into the through hole (6) at both ends.
A round bar (2) (2') with a protrusion (3)
) is passed through, and the center of the round bar (2) (2') is welded and integrated with the base plate (1), and then the base plate (1)
) to complete the joint reinforcing hardware for wooden buildings of the present invention.

(Function) First, insert holes (7) for the round rods (2) (2) into the upper and lower edges of the pillar (9), and then insert the insertion holes (7) at the upper and lower edges.
), insert the round rods (2) (2') and drive the nails (8) into the upper and lower edges of the pillar (9) through the nail holes (5) in the base board (1), and then secure the pillar (9). The installation of hardware to the upper and lower small [1 is completed. The lower part of the pillar (9) is attached using a round rod (2) that is pre-drilled and placed on the base (10).
Insert the round metal rod (2) (2) attached to the lower edge of the pillar (9) into the insertion hole (7) of (2'), attach the pillar (9), and then insert the beam (11). The insertion hole (7) for the round rod (2) (2') that has been pre-drilled at the bottom of the
A round metal bar (2) attached to the upper edge of the pillar (9).
This is a joint reinforcing hardware for wooden buildings that can be completed by dropping the beam (11) in line with (2').

(Example) An example of the present invention will be described with reference to FIG. −
The base plate (1) is a raw steel plate with a square shape of about 10 cm on a side and a width of about 4 mm to 6 mm. On the center line of the base plate (1), about 13 mm thick through holes ( 6)
are drilled in two places, both ends of which are machined into a semicircular shape (4), and the protrusions (3) are passed through the machined round bars (2) (2') of about 12mm. and the round bar (2) (2'
) is welded to the base plate (1) to secure it to the base plate (1), and nail holes (5) are drilled around the outer corners of the base plate (1) to form the base plate (1) for use in wooden buildings of the present invention. Joint reinforcing hardware is obtained.

Also, as shown in FIGS. 2 and 3 as an example of the use of the present invention,
For example, the column (9) is a joint reinforcing hardware for wooden buildings that can be easily and firmly attached to the foundation (10) and fR (11) via the joint reinforcing hardware of the present invention.

C [Effect of the invention] The pillar (9) and the base (
10) and the beam (11) are joints as shown in Figure 4, but the slots can only be machined with a power saw; If you cut too much at the base of the tenon, the tenon will become weak, and if you don't cut it vertically and horizontally, the pillar will not stand up vertically, and the tenon is constant because it is machined only with an electric angle, but the tenon on the pillar is too large. It must not be too small or too small, or the electric saw must be operated at least 9 times to process it, and the electric saw also requires a large electric saw, and it is also heavy and dangerous, making the work difficult. However, using the joint reinforcing metal fittings of this invention, it is difficult to use the joint reinforcing metal fittings of this invention.
The base (10), beam (1) and other members are installed as shown in Figure 4.
1. Cut the upper and lower small r"I of the rod (9) vertically with an electric saw without needing to cut the holes (7) into the round rods (2) (2').
Ink ①; 1 point, the insertion hole for the electric drill (7)
For drilling +-+, use the electric drill to attach 1 to the base (10) and beam (+1), and use the electric drill to insert the round rod (2) (2') into the hole (7). Since the ft is completed by drilling the insertion hole (7), the quality of the joint is uniform and there is no unevenness depending on the operator's joint strength, so it is possible to reduce the need for skilled labor and reduce the amount of time required. The effective length of the rod (9) is somewhat unknown due to the groove machining, but by using the hardware of this invention, ff (!': ', )
Since it is possible to use almost the same length as it is, it is a joint reinforcing hardware for wooden buildings that is extremely efficient and can increase efficiency in terms of materials and workability.
