Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention is suitable for building buildings using conventional framework construction methods or using other construction methods such as frame construction methods. The present invention relates to a joint device for building members.

0002

BACKGROUND OF THE INVENTION As conventional building construction methods, the frame construction method and the frame construction method are well known. The former is also called the skeleton skin construction method or the post and beam construction method, and is a construction method that mainly consists of columns and beams.

The latter is also called the two-by-four construction method or the platform frame construction method, and is a floor formed by nailing structural plywood or a facing material with performance equal to or higher than that of structural plywood to a floor framework made of joists. 2. The wall formed by nailing structural plywood or similar material to the framework of the wall constructed of frame materials is removed with nails and hardware.
It is the purpose of constructing a building.

[0004] To compare and describe the main differences between these construction methods, first, the space structure is ``axis (line)'' in the former, and ``pane (plane)'' in the latter. The structure that provides rigidity for floors, walls, etc.
The former is ``flint and bracing,'' and the latter is ``structural plywood.'' The wood used is ``mainly square wood with large cross sections and long pieces (through-posts),'' and the latter ``mainly consists of small cross-sections and short pieces of wood.'' The construction process for the former is "1st floor/2nd floor axis, continuous construction of the shed, floor", for the latter is "1st floor floor → 1st floor wall → 2nd floor floor → 2nd floor wall → hut (step work)"
It is.

[Problem to be Solved by the Invention] Conventionally, in the construction of buildings such as wooden houses, after constructing the foundation,
Architectural components such as wood are skillfully cut and notched, and these are skillfully assembled and connected in accordance with structural mechanics, and important connecting parts of architectural components are especially fixed with bolts and the like. However, such traditional methods require a high degree of skill and skill to connect building components, are inferior in work efficiency, economical efficiency of building components, strength of joints, etc., take a long time, and end up being expensive.

On the other hand, although recent prefabricated buildings have solved some of the above economical problems through mass production, they are inferior in durability and strength (particularly in joints), lack diversity, and have a short period of use after construction. Over time, they become shabby, and when used for a long time, they no longer give off the sense of calmness and weight of architecture. Therefore, as a result of many years of intensive research into the connection of structural members such as those described above, the applicant of the present application has found that it is easier than the conventional simplest connection method, for example, the method of combining various types of steel plates and bolts and nuts, and that We have developed a joint for architectural components that is superior in strength to the traditional wooden carving method.

[0007] This is clarified by Japanese Patent Laid-Open No. 107626/1983. That is, in this joint, a plate-like member extending outward from the surface of the basic joint body in a plane substantially orthogonal to the surface is welded and fixed to a basic joint body having a cubic or rectangular parallelepiped shape. The shaped member is provided with a hole through which a fastener such as a bolt can be inserted. Many types of joint members can be obtained by combining the basic joint member main body and the plate-like member with different shapes, numbers, and directions.

However, such conventional joints have the following problems. That is, as a result of applying a basic joint body having a cubic or rectangular parallelepiped shape as described above, the weight of the joint is considerably increased and a large amount of material is required, which is disadvantageous in terms of cost. In addition, as a result of the heavy weight, it is difficult to handle and it is difficult to join construction components together. Further, in manufacturing the joint, there are many welding points, which requires a lot of man-hours, and the manufacturing efficiency is poor.

Furthermore, with conventional joints, it is necessary to use different types of joints for coupling columns, beams, columns, beams, etc., so it takes time and effort to manufacture the joints. It takes a lot of time and its management becomes complicated. In view of the above conventional problems, the present invention makes it possible to use standardized pre-cut members as building members, and provides a standardized joint member suitable for joining these members to form a framework of a building. To provide a joint device for building components that can be effectively constructed in either a building using a conventional frame construction method or a building using a frame construction method. It is an object of the present invention to provide a joint device for building members that can reduce costs by reducing material costs, standardize joints into a single type, and improve the manufacturability of joints. .

[0014] Here, the outer corner portions of each of the plate portions 3, 6, and 7 are cut into a triangular shape. Further, the plate parts 3 and 7 and the plate part 6 are fixed by welding. In this case, the corner of the second connecting plate part 6 located at the corner formed by the joint part of the first connecting plate part 3 and the receiving plate part 7 is cut into a triangular shape, and the welding member is This prevents it from accumulating in the corners.

The bolt insertion holes 2 of the first connecting plate part 3 are opened at respective positions on both sides of the first connecting plate part 3 with the second connecting plate part 6 between them. The bolt insertion holes 2 at each position are set to be aligned on the same line in the lateral direction. The bolt insertion holes 5 of the second connecting plate part 6 are opened at two positions spaced apart in the vertical direction. Incidentally, the upper bolt insertion hole 5 is formed as a long hole in the vertical direction.

[0016] The shear connector is arranged to resist the shearing force generated at the joint when two members are joined and integrated, and in this embodiment, one end is closed. The shear ring 4 is made of a short cylindrical shape and has a sharp tip at the open end. A bolt insertion hole 4a is provided in the center of one closed end wall of the shear ring 4.

The shear ring 4 is fixed in advance by welding to the outer surface of the first connecting plate 3 opposite to the fixing surface of the second connecting plate 6 at the position where the bolt insertion hole 2 is formed. At this time, the bolt insertion hole 2 and the bolt insertion hole 4 of the shearing 4
Make sure that the a position matches. Here, the direction connecting the opposite side surfaces of the pillar 8 shown in FIG. In this case, the connectors 1 located on the X axis and the Y axis are the first
The opening position of the bolt insertion hole 2 provided in the connecting plate part 3 is shifted in the vertical direction. This is to prevent the bolts passing through the pillar 8 from passing through shifted positions and overlapping each other.

Further, the number of bolts for fixing the first connecting plate portion 3 to the pillar 8 is not limited to one each on the left and right sides, but a plurality of bolts may be provided. In this case, the number of bolts should be used depending on the dimensions of the beam. For example, if the dimension of the beam is 8 inches or more, as shown in FIG. Bolt insertion holes 2 may be provided at two positions, and the first connecting plate portion 3 may be fixed to the pillar 8 using two bolts on each side.

Furthermore, the dimensions A and B of each part of the connector 1 shown in FIG. 1(B) are set according to the dimensions of the beams to be connected. Next, the manner in which the connector 1 having such a configuration is fixed to the pillar will be explained. In FIG. 6, a single connector 1 is fixedly attached to one side of a column 8. In this case, as shown in FIG. 11, the bolt 9 inserted from the first connecting plate 3 of the connector 1 is passed through the insertion hole 8a of the column 8, and the nut 10 is fitted to the protruding end of the bolt 9 from the column 8. match. The protruding end of the bolt 9 and the nut 10 are inserted into a counterbore 11 provided in the column 8 in advance. Here, the shear ring 4 is inserted into a small ring-shaped positioning groove 12 formed in advance on the pillar 8, as shown in FIG. Then, by tightening and fixing the first connecting plate part 3 to the pillar 8 with the bolts 9, the first connecting plate part 3 is deeply fitted into the pillar 8.

FIG. 7 shows a structure in which the connectors 1 are fixedly attached to two adjacent sides of the pillar 8, respectively. In this case, the two connectors 1 used are the aforementioned X-axis connector and Y-axis connector 1. In FIG. 8, connectors 1 are fixedly attached to both opposing sides of a column 8, respectively. In this case, the aforementioned X-axis connector 1 is used as the two connectors 1.

FIG. 9 shows a structure in which the connectors 1 are fixedly attached to both opposite side surfaces of a column 8 and one side surface adjacent to the both sides. In this case, as the three connectors 1, one connector 1 for the X axis and two connectors 1 for the Y axis are used. In FIG. 10, the connector 1 is fixedly attached to each of the four sides of the pillar 8. In this case, two connectors for the X-axis and two connectors for the Y-axis are used as the four connectors.

Connector 1 fixed to pillar 8 as described above
In order to fix the beam 13 to the beam 13, as shown in FIG. Set the beam 13 on the receiving plate part 7 so that the bolt 1
4 and tighten using nuts. In addition, the above-mentioned pillar 8 may be a 3.5 inch square one in the case of a one-story building, a 3.5 inch square one in the case of a two-story building, or a 606 through pillar (wooden board with the fiber direction in the length direction). In the case of a three-story building, 606 through columns (the above-mentioned laminated wood) are used, respectively.

[0023] The beam 13 should be 3.5 inches wide for a one-story building, 3.5 inches wide or 90 mm wide for a two-story building, and 90 mm wide for a three-story building. Each of the above is used. 13 and 14 are column 8
Figure 13 shows an example in which the connector 1 described above is used at the joint between the column 8, the girder 15, and the beam 13 in the conventional frame construction method. 8 [3.5 dimensions x 3.5 dimensions (105 x 105)], by using the connector 1 as shown in Fig.
．． 5 size x 3.5 size (105 x 105)] and beam 13 [3.
5 size x 3.5 size (105 x 105)].

FIG. 14 shows a building construction method previously proposed by the present applicant (see Japanese Patent Laid-Open No. 63-233137).
This is an example in which the above-mentioned connector 1 is adopted for the connection part between the column 8, the girder 15, and the beam 13, and the through column 8 [60
6 (140 x 140)], the girder 15 [3.5 dimensions x
8 sun (105 x 242)] and beam 13 [3.5 sun x 8 sun (
105×242)] are combined.

In the above embodiment, the shear ring 4 fixed to the plate portion 3 by welding is used as the shear connector, but the shear ring 4 may be constructed as shown in the embodiments shown in FIGS. 15 and 16. In this embodiment, triangular cut grooves 16 are provided at a plurality of locations on the plate portion 3, and the wall of the plate portion 3 is raised up according to the cut grooves 16, so that the triangular claw portions 17 are formed on the plate portion 3. The triangular claw portion 17 is formed to protrude from the outer surface and is configured as a shear connector. In this case, when forming the plate portion 3, press working may be performed to raise the plurality of claw portions 17 all at once.

According to the connector 1 described above, since it has a simple structure consisting of the three plate parts 3, 6, and 7, it is possible to reduce the weight and material of the joint device, thereby reducing costs and reducing the weight. As a result, it is easy to handle and it is easy to connect building components. Further, in manufacturing the connector 1, the number of man-hours is small, such as the number of welding points is small, and the manufacturing process is excellent.

[0027] Here, noteworthy features of the above connector 1 will be explained. As a construction method using a conventional construction component joint device, multiple columns are connected with a connector without using through columns, and another connector is connected to this connecting part.
There are some connectors that use a method of connecting beams, etc., but these connectors come in many different types, making it difficult to manufacture and
There are problems with assembly, etc.

[0028] Therefore, the present inventor proposed using one type of connector, and therefore proposed the use of a through-post. That is, we proposed a method of connecting a connector to a through column and connecting a beam, etc. to this connector. In this case, simply joining the connector to the through post cannot resist the shearing force generated at the joint between the through post and the connector, and strong bonding strength cannot be obtained.

Therefore, the inventor further fixed to the connector 1 a shear ring 4, which has a short cylindrical shape with one end closed and has a sharp tip at the open end, as shown in the embodiment. However, by deeply inserting the shear ring 4 into the pillar 8, the inventors devised a method to resist the shearing force generated at the joint between the pillar 8 and the connector 1, thereby obtaining a strong bonding strength.

[0030] By devising the connector 1 as described above, it is possible to use a single type of connector 1, it does not take much time to manufacture the connector 1, it is easy to manage, and it is possible to significantly save labor and reduce costs. This made it possible to reduce the amount of processing required for building components, eliminate the need for skilled engineers, and shorten the construction period. By using such a connector 1, the connection of building members can be completed by simply using a fastening means such as bolt tightening. In addition, since the connector 1 and the building components connected by it can be standardized, the connector 1
All of this can be prepared at the factory, and only the building materials that will be used can be pre-cut and prepared at the factory. Furthermore, the connection of building members using the connector 1 is extremely strong, and the strength is overwhelmingly greater than conventionally known methods using mere steel plates or bolts and nuts.

Furthermore, the strength and precision of the structure depends on the skill and skill level of the carpenter who is doing the construction, but by using the above-mentioned connector 1, any person can do the work regardless of the skill or level of skill. Constant, uniform strength and precision can be expected. In particular, in the conventional framework construction method that uses the connector 1 with the above-described unique configuration, when connecting building components, the joints and joints that were conventionally provided on the building components are replaced with the connector 1 described above. In addition, since the pillar 8 only needs to be processed to provide an insertion hole for the bolt 9, it does not require a high degree of skill and skill to connect the building parts, and it improves work efficiency and building parts. It has excellent economic efficiency and strength of the joint parts, and can reduce costs by shortening the construction period.

[0032]Also, in the building construction method previously proposed by the applicant, a plurality of pillars are connected to each other by connectors as described above, but the use of the connector 1 is as follows: As the condition is that the use of As mentioned above, although the present invention has been described with reference to specific examples, the present invention is not limited thereto. It should be noted that various changes and modifications are possible without departing from the scope.

[0033]

[Effects of the Invention] As explained above, according to the joint device for building members of the present invention, a single type of joint members can be used uniformly, the manufacturing of the joint members does not take much time, and management is easy. This enables significant labor savings and cost reductions, reduces the number of parts processed into building components, eliminates the need for skilled engineers, and shortens the construction period.

[0034] Furthermore, as a joint device, weight and material can be reduced, costs can be reduced, and the work of joining building members can be simplified and work efficiency can be further improved. or,
It has excellent manufacturability, and it is difficult for errors to occur in dimensions between building components. Furthermore, since a single type of joint device for building components can be used, it does not take much time to manufacture the joint device for building components.
It is also easy to manage, allowing for significant labor savings and cost reductions.

In particular, the construction method using the joint device of the present invention does not require complicated joints or joints, there is no variation in structural strength, and the connection of construction members is extremely strong. In addition, construction work is extremely easy to perform, the construction period can be significantly shortened, and it is extremely economical. Various types of buildings can be constructed one after another according to the demands of users using a small number of standardized products. It can also be applied to the conventional framework construction method and other construction methods. In particular, in the conventional framework construction method, when connecting building components, the present invention can replace joints and joint members that were conventionally provided on construction components. It can be replaced with a joint device for building components, and in the case of columns, since the only processing required is to provide holes for bolts, there is no need for a high degree of skill and skill to connect construction components, and the work is easy. It has excellent efficiency, economical use of building materials, strength of joints, etc., and can reduce costs by shortening the construction period.
