Description

Detailed Description of the Invention (Object of the Invention) The present invention relates to a novel structure of a brace member mainly used in wooden buildings, and relates to a brace member with an inexpensive structure that is advantageous in handling workability. This is what we are trying to provide.

(Prior Art) In buildings with frame structures, braces are structurally extremely important members, and the minimum amount of braces used is strictly regulated depending on the scale of the frame structure. However, unlike other frame members, it is used as a diagonal member, which makes processing and construction extremely complicated, so it would be better if it could be used as little as possible. However, there is a tendency to try to perform with the minimum amount of energy used, and it can be said that the situation is not necessarily favorable in terms of structural strength.

Furthermore, even if the amount of wood used is kept to a minimum, in the current wooden buildings, it is difficult to process the wood depending on the location where the braces are installed. Compared to that, it is much more complicated, and there are reports that many craftsmen have been injured during the processing process.

Therefore, in order to eliminate these conventional inconveniences, the applicant of the present application has already developed and proposed a brace member with a new structure using reinforcing bars, for example, as in the invention of Japanese Patent Application No. 61-69372. It has also been successfully put into practical use.

This differs from previous models that used reinforcing bars with turnbuckles, and there is little risk of the reinforcing bars protruding outward from the surface of the columns and studs, and it has a structure that is easy to work on site. However, when a pair of brace members are crossed and used in an X-shape, there is a concern that some inconvenience may occur due to ease of use.

This invention aims to address such anticipated difficulties.
As a result of intensive research and development, we have finally succeeded in developing and realizing a brace member with a completely new structure as detailed below.

(Structure of the Invention) As is clearly understood from the representative embodiment of the present invention shown in the drawings, the brace member of the present invention is made of a pair of reinforcing bars 1°1' having an appropriate thickness and length. Inside, one of the reinforcing bars 1 is cut into parts by cutting approximately the center part thereof, and approximately the reinforcing bars 1 are cut into sections.
At the same time, a predetermined width of one end of the metal plate is attached to one end side of each of the pair of reinforcing bars 1, 1'. A piece 21 is bent approximately at right angles to the back side according to a folding line inclined at a predetermined angle θ with respect to the longitudinal side edge of the plate, and the side bent to a predetermined width is latched.
The remaining part is used as the fixed piece 22, and at least the fixed piece 2
2, the back surface of the fixing piece 22 of the L-shaped metal bending fixing plate 2, which has nailing holes 23, 23, and port insertion holes 24 formed therein, is integrated at the required locations of 2, and each of the reinforcing bars 1° The other end of 1- is a simple flat metal plate, with nailing holes 33, 33...
. . . and the back surface of a flat metal fixing plate 3 formed with bolt insertion holes 34 are integrated as appropriate.

The pair of reinforcing bars 1.1 are adopted by cutting reinforcing bars having an optimal thickness according to the required structural strength and suitably cutting them to the required length at the location where the reinforcements are to be installed.

The thin iron plate piece 11 attached to the part of the reinforcing bar 1 on the side that is parted from approximately the center of the pair of reinforcing bars 1, 1- is approximately the same as the part of the reinforcing bar 1a, 1a. It is the thickness of the reinforcing bars 1. It is connected and integrated by separating the reinforcing bars 1a and 1a, and the reinforcing bars 1a and 1a are firmly integrated by welding or other means to provide sufficient tensile strength. It must be something that can be demonstrated. Moreover, the location must be exactly opposite to the location where the L-shaped metal fixing plate 2 or flat metal fixing plate 3, which will be described later, is fixed, that is, the exact back side when viewed from the reinforcing bars 1a, 1a.

The L-shaped metal fixing plate 2 is formed by bending a flat metal plate so as to form an inverted L-shape in the side profile, and the side that is bent over a predetermined width on one end is the latching piece 2.
1. The remaining part is the fixed piece 22.
The bending point of the latching piece 21 is a bending line inclined at a predetermined angle to the vertical side edge of the metal plate, that is, an angle θ equal to the angle formed by the brace and the girder or beam at the location where the brace is installed. The section must be in accordance with the above.

In the figure, 25 is a claw protruding from the edge of the latching piece 21, which prevents the latching piece 21 from slipping when it is latched, and may be adopted as necessary for work efficiency. good.

In addition, nail holes 26°26 are formed at important points on the latch piece 21.
However, the latching piece 21 itself is attached to the top of the beam or girder 4 in order to make it possible for workers to manually work on the brace member of the present invention at the stage of installing the brace member. This nailing hole 23 can be omitted in some cases since it mainly serves the function of temporary fixing by hooking it on the end face, but from the viewpoint of increasing the overall fixing strength of the member, this nailing hole 23 , 23... can be said to be preferably formed as much as possible.

This pair of reinforcing bars 1.1- can be used individually as ordinary braces, but as shown in the second drawing, first the reinforcing bars 1.1- are cut into parts and have thin iron plate pieces 11. 1 is fixed diagonally, and using the gap between the reinforcing bars 1a and Ia on the thin iron plate piece 11, the other reinforcing bar 1- that is not cut is
The first principle is to realize a so-called X-shaped brace, which is fixed in a cross-shaped manner.

Hereinafter, specific examples of preferred actual IM aspects of the brace member of the present invention will be explained with reference to the drawings.

(Preferred Practical tM Embodiment 1) As in the embodiment shown in the overall perspective view shown in FIG. Installed stud 7 (,7...)
Nailing holes 14 () are pre-drilled at important points in the thin iron plate piece 11 to enable nailing to the metal plate.

14...) are drilled.

In addition, in the above-described embodiment, the L-shaped metal fixing plate 2 and the flat metal fixing plate 3 for the pair of reinforcing bars 1-1 are examples of brace members that are integrated by welding or other known means. Therefore, the overall length dimension is limited to a certain configuration at the stage of manufacture.

(Preferred Practical Embodiment 2) On the other hand, the L-shaped metal fixing plate 2 and the flat metal fixing plate 3 in the brace member of the present invention are formed into strips as shown in FIG. As shown in the enlarged front view of the fifth solid part, each is formed into a large plate 2- (or 3-) spanning the pillars 6 and horizontal members 4 such as hooks and girders. By doing so, it is possible to realize a brace member that also has a reinforced joint portion.

(Preferred Aspect 3) In the case of the embodiment shown above, the brace member to be formed is of a fixed length, but in the embodiment shown below, the dimensions are adjusted as appropriate depending on the situation of the location where the brace is installed. An example of a brace member having a structure that enables this is shown.

That is, the back surface of the L-shaped metal fixing plate 2 is integrated with one end side of each of the pair of reinforcing bars 1, 1', as in the above configuration, while On the other end side, a reinforcing member is realized by integrating the reinforcing bars 1, 1- and the back surface of each flat metal fixing plate 3 so as to have a length adjustment structure.

To give a more specific example of this configuration, as shown in the enlarged front view of the third fixed part and the enlarged cross-sectional view of the fourth fixed part, the length adjustment structure of the brace member described above is The end of the reinforcing bar on which the thread 12 is formed is inserted into the sheath pipe 31 fixed to the back surface of the molded metal fixing plate 3, and the nut 13 is screwed onto the thread 12 of the end of the reinforcing bar. This is realized by supporting the oaks 1 to 13 on the ends of the sheath tube 31. In the figure,
Reference numeral 32 indicates a cut hole provided in the flat metal fixing plate 3 for rotating the nut 13.

In the illustrated embodiment, a pair of nuts 13 are arranged above and below the sheath tube 31, but the upper nut 13 may be omitted depending on the case.

In addition, in the illustrated example, the sheath tube 31 is formed to have a hollow portion with the same diameter from top to bottom, but if the arrangement angle of the entire brace member is to be made changeable, The hollow portion of the sheath tube 31 may also have a truncated conical hollow portion. However, when adopting this configuration, a fixing structure that can change the angle as appropriate is not required to be formed not only on the flat metal fixing plate 3 side having the length adjustment structure but also on the L-shaped metal fixing plate 2 side. Needless to say.

Next, by replacing the fixing plates integrated at each end of the pair of reinforcing bars 1 and 1' with fixing plates having the following configuration, a more advantageous brace member can be realized. be able to.

That is, a pair of reinforcing bars 1.1' having appropriate thickness and length.
Inside, one of the reinforcing bars 1 is sectioned by cutting its approximately central part, and then connected into a single piece with thin iron plate pieces 11 at intervals approximately equal to the thickness of the reinforcing bars, and a pair of reinforcing bars 1 are 1,1'
A brace member is constructed by integrating the back surfaces of flat metal fixing plates 3, 3, . . . on both ends of each.

(Preferred Embodiment 4) In the brace member of the above structure, as shown in the example shown in Drawing 6, the thin iron plate piece 11 formed on one of the reinforcing bars 1 can be nailed to the stud 7. Nailing hole 14 (,14...
) is formed, it is possible to realize a brace structure with enhanced integrity with the frame member.

(Preferred Embodiment 5) On the other hand, the flat metal fixing plate 3 in the brace member of the present invention is formed into a rectangular shape as shown in FIG. By forming it on the large flat metal fixing plate 3' as shown in FIG. can.

As can be understood from the embodiment shown in FIG. 7, the large flat metal fixing plate 3''', which is referred to as a large plate, straddles the horizontal members 4 such as beams and girders and the columns 6! ) [It is of a structure having a sufficient size to be passed over, and its shape is not particularly limited.

(Preferred Embodiment 6) In the cases shown in Embodiments 4 and 5 above, the brace members formed are of a fixed length, but this embodiment also has the same structure as that adopted in Embodiment 3 above. , it is possible to form a structure having a configuration that allows the dimensions to be adjusted as appropriate depending on the situation of the location where the brace is installed.

That is, it is a brace member in which at least one side of each of the pair of reinforcing bars 1.1- is integrated with the back surface of the flat metal fixing plate 3 so as to have a length adjustment structure. And, for the length extension (j4 structure), a structure similar to that specifically shown in the third embodiment is adopted.

(How to use) All of the brace members of the present invention represented by the above embodiments are produced in a factory and delivered to the site, and at the location where the braces are installed, a worker places the L-shaped metal fixing plate 2 side up. Hold the hanging piece 21 of the metal fixing plate 2 to the horizontal member 4 such as a beam or girder (for the first floor of a two-story building, the same applies below).
Hook it on the upper end surface of the

In places where a single brace member is sufficient for forming braces, there is no particular problem in adopting either of the pair of reinforcing bars 1.1', but cross-shaped braces must be formed. At this point, among the pair of reinforcing bars 1.1', the reinforcing bars 1 having the thin iron plate pieces 11 are constructed according to the work described above.

Then, the flat metal fixing plate 3 of the suspended reinforcing bar 1 is attached to the base 5 (for the second floor of a building, it is a trunk mount. The same applies hereafter. In addition, if the fixing plate 3 is made of a large plate 3' , this sill or base 5 and the pillar 6) are nailed and bolted. Below, after proceeding with the work in the same way for the places where braces are required,
At the location where cross-shaped braces are to be formed, the reinforcing bars 1-, on which the thin iron plate pieces 11 are not formed, of the pair of reinforcing bars 1. The work is carried out in the same manner as above, so as to intersect with Material 1.

In this process, the approximate center of the reinforcing bars 1' fits into the gaps between the reinforcing bars 1a and 'la formed on the thin iron plate piece 11, so that the reinforcing bars 1.1-- do not overlap each other.

When the fixation of the flat metal fixing plate 3 side is completed in this way, go up to the horizontal frame member 4 and hang the L-shaped metal fixing plate 2 on the horizontal frame member 4 (the fixing plate 2 is made of a large plate). Thing 2
- In the case of -, it is correctly fixed to the pillar 6) together with this cross member 4 and rotates.

If necessary, the reinforcing bars 1 are attached to the studs 7 (, 7, . It is also possible to further increase the structural strength by attaching it to ...).

The brace member in this work process can be easily and efficiently installed by one worker without requiring any auxiliary worker.

However, as in the example shown in FIG. 6 or 7, in places where the latching piece 21 cannot be latched to the horizontal member 4 because it is obstructed by a pillar, both ends of the latching piece 21 are attached to the flat metal fixing plates 3, 3. Form the brace with the brace members.

In addition, during the construction process, the length of the brace installation location may change due to correction of the verticality of the pillar 6, etc., and it may become necessary to adjust the length of the brace members or change the location or floor plan. In case the length of the brace at the brace installation location changes due to changes, etc., if a brace member with a length adjustment structure is adopted in advance, the length adjustment structure can be operated at appropriate stages while on-site. Able to work according to the situation.

(Operation and Effect) The brace member of the present invention having the above-described configuration includes a pair of reinforcing bars 1.1', one in which a thin iron plate piece 11 is combined with the partial reinforcing bars 1a and 1a, and the other in which the reinforcing bars 1.1' are not combined. Each can be used independently, and when both are combined and crossed in an X-shape, the other reinforcing bar 1' fits into the gap between the partial reinforcing bars 1a and 1a, and the reinforcing bar 1 It has the great feature that the layers 1' do not overlap, and there is no risk of any hindrance to the subsequent work of forming the base.

Of course, even if any one of the pair of reinforcing bars 1.1' is used as a single brace member, each of the fixing members 2 and 3 is attached to the surface side of both ends of the reinforcing bars 1 and 1. Since it uses a fixed structure, only the thickness of each fixed plate 2 and 3 needs to protrude from the column surface to fit neatly, and the installation of the base material, etc. that must be installed at that time is easy. Needless to say, this has the advantage of not causing any structural disadvantage.

The pair of reinforcing bars 1.1' may have an L-shaped metal fixing plate 2 and a flat metal fixing plate 3 integrated at both ends, or may have flat metal fixing plates 3.3 at both ends. Either an integrated version or one in which each of the fixing plates 2.3 consists of a large plate is provided as a ready-made member, and it is easy to handle it on site as well as to install it at the brace installation location. This method is far more advantageous than conventional braces in terms of ease of construction work.

In particular, in the case where the L-shaped metal fixing plate 2 is adopted as the fixing plate, the effect that the latching piece 21 enables the worker to form the braces by himself is effective in improving the efficiency of construction. It can be said that it is very useful, and if the fixing plates 2 and 3 are made of large plates, the installation of braces can directly lead to strengthening of the joint, which is a feature in terms of structural strength.

Furthermore, since these brace members can be used without being processed at the cutting site, there is no need to worry about injuries caused by tools during on-site processing, unlike with conventional wood braces, making them safe and efficient. This will ensure that the work will be done in a timely manner.

In addition, even if the dimensions of the brace at the location where the braces are installed change due to site conditions, this can be easily accommodated by adopting brace members that have a length adjustment structure in advance. Even when adjusting the length, there is no need for on-site processing, and the work can be carried out safely and efficiently.

In particular, the length adjustment structure has a nut 13 screwed into the thread 12 formed at the end of the reinforcing bar 1, and supported by the sheath pipe 31 on the back surface of the flat metal fixing plate 3. In addition to being easy to manufacture, the adjustment operation is simple and the workability is extremely high.

The characteristics of the brace strength are that the thickness cross-section of the reinforcing bar 1 can be freely determined in advance according to the design value at the manufacturing stage, resulting in a brace member with less variation, and if necessary, It can also be formed into a structure in which the reinforcement is crossed in a letter shape, and the membrane distortion of the design strength is extremely flexible, making it possible to realize efficient braces that take economic efficiency into account. are doing.

In addition, nailing holes 14 (, 1
4...) are formed in advance, and the nailing holes 14 (,1...) are formed in advance.
4...) to fix the brace members to the studs 7, the brace strength can be further increased.

As mentioned above, the brace member of the present invention is composed of a combination of a pair of reinforcing bars with different structures, and has the advantage of being able to be used as a single brace member as well as being able to be used in combination in an X-shape. In addition, the structure is [1], and it can be easily manufactured as a ready-made member, so it is versatile, has stable quality and strength, and can be used as an inexpensive member. Moreover, it is highly workable on site, allowing the formation of braces in buildings, especially wooden buildings, to be carried out safely and efficiently, and of course streamlining construction work. It is expected that this will greatly contribute to increasing the strength of buildings. ′
