Description

The present invention relates to a stud, a bearing wall base material and a bearing wall.

In a building such as a detached house or an apartment house, a base structure in which a load-bearing element such as a brace is passed inside a base material of a wall (within the thickness of the base material) may be applied. In a load-bearing wall with this type of underlayer structure, in order to avoid interference between the load-bearing element and the base material, the backs of two grooved steel webs are brought into contact with each other to form a stud, and the stud's load-bearing element interferes. In some cases, a base material is used in which an insertion hole is opened in a portion to be inserted and a load bearing element is inserted. In some cases, a three-layer structure stud including two outer studs having a height corresponding to the floor height and a plurality of short inner studs arranged between the two outer studs may be applied. According to the stud having the three-layer structure, the load bearing element can be passed inside the base material by disposing the plurality of short inner studs in the center at positions avoiding the load bearing element.

An outline of the method for constructing the above-mentioned three-layer structure stud is as follows. That is, at the construction site, after structural structures such as columns and beams are assembled and load bearing elements such as braces are installed in the construction surface, studs that form load bearing walls are installed so as not to interfere with load bearing elements. Be seen. At the construction site, after attaching one outer stud to the construction surface, a plurality of inner studs are fixed with screws or the like at a position of the outer stud that does not interfere with the load bearing element. Next, a plurality of inner studs fixed to one outer stud is fixed to the other outer stud with a screw or the like, so that a stud having a three-layer structure in which a load bearing element is passed inside is constructed. At this time, the inner stud is manufactured by on-site processing in which a long stud carried into the site is measured to a predetermined length and cut. This on-site processing also includes drilling such as screw holes, and these cutting and drilling are relatively dangerous operations involving the generation of sparks and are laborious on-site processing. Even in the stud formed by bringing the back surfaces of the two grooved steel webs into contact with each other as described above, since the punching of the insertion hole through which the load-bearing element is inserted is performed on-site, Have similar challenges.

The angle of the brace, which is a load-bearing element, changes according to the height (floor height) and width of the building, and the height position at which the brace passes on the stud changes. For example, in a three-story house, the heights of the first floor to the third floor are often different, and since there are various beams, the height between the upper and lower beams is Therefore, the height of the bearing wall and the mounting position of the brace to the pillar also vary in a single building. Further, the width of the load bearing wall has various forms such as 0.5P (1P is 910 mm), 1P, 1.5P and 2P. In addition, depending on whether the load-bearing wall is installed near the wall or at a position where the opening in the middle of the wall is bypassed, the left and right columns of the load-bearing wall are in the form of one single pillar and two double pillars. The width of the bearing wall varies depending on these various factors. As described above, the height and width of the load-bearing wall are different based on various factors, so that the angle of the brace changes, and as described above, the height position through which the brace passes in the stud changes.

On the other hand, in order to form a three-layered stud having a constant strength, the space between the short inner studs needs to be set within a predetermined space. Therefore, the mounting position of the inner studs and the number of mounted studs will change for each bearing wall of each part of the building, and together with the production by cutting and drilling at the site, construction of the base material There was a problem that it takes a lot of time and effort.

Here, regarding a load bearing wall provided with braces, two or more first diagonal members arranged in parallel with each other and two or more first diagonal members inclined in a direction opposite to the first diagonal member. And two or more second diagonal members that are parallel to each other and are arranged so as to intersect with each other, all the first diagonal members are arranged on the same plane parallel to the wall surface of the load bearing wall, and all the second diagonal members are arranged. A load bearing wall in which a diagonal member is provided on the indoor side of the first diagonal member has been proposed (see, for example, Patent Document 1).

JP, 2014-234646, A

Also in the load-bearing wall described in Patent Document 1, as described above, the studs forming the base material of the load-bearing wall are formed by abutting the back surfaces of two webs of channel steel to form a stud brace. A configuration is adopted in which an insertion hole is formed at a position where it interferes, and a brace (here, diagonal member) is inserted into the insertion hole. And although it is not specifically described in Patent Document 1, as described above, it is sufficiently assumed that the insertion hole is drilled at the position where it interferes with the brace of the stud at the construction site, and as described above. In addition, since it is necessary to perform on-site drilling at a unique position for each load bearing wall of various dimensions with different floor heights and widths, it involves the above-mentioned problem that it takes a great deal of time to construct the base material. obtain.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a stud that eliminates the need for machining in the field, a load bearing wall base material having the stud, and a load bearing wall having the load bearing wall base material. I am trying.

In order to achieve the above object, one aspect of the stud according to the present invention is:
A stud forming a bearing wall,
An inner stud modularized in advance in a relatively short length,
Has two relatively long outer studs,
A plurality of the inner studs are arranged at intervals between the two outer studs.

According to this aspect, in the stud formed by the two outer studs and the plurality of short inner studs arranged between them, the inner stud is manufactured in advance in a factory or the like and is modularized. By doing so, it is possible to eliminate the need for cutting the inner stud on site and greatly improve the stud construction time. Here, "preliminarily" means that the inner stud is preliminarily cut into a predetermined length in a factory or the like, and the through holes for fixing means such as screws are perforated. .. That is, there is no need for cutting or drilling the inner studs at the site. Since the outer studs corresponding to the floor height do not require cutting work or the like on site, the outer studs are similarly manufactured in advance in a factory or the like.

Further, “modularization” means that the lengths of the inner studs are uniformly set, and for example, the lengths of 100 mm and 150 mm are uniformly set. Even when load-bearing walls of various sizes and shapes with different heights and widths exist on each floor of the building, the short inner studs that make up the three-layer structure studs are modularized, so The complexity of mounting is largely eliminated.

For example, a 1.5P-width load-bearing wall has, for example, three studs, and a 2P-width load-bearing wall has, for example, four studs, but each stud has a different position where it interferes with a load-bearing element such as a brace. A plurality of inner studs are attached between the two outer studs so that the studs do not interfere with the brace and the clearance is within the range of 500 mm to 800, for example. For a stud forming a load bearing wall having a floor height of about 2500 mm, for example, about 5 to 8 inner studs modularized to a height of 100 mm can be applied.

Further, one aspect of the load bearing wall base material according to the present invention is
Upper and lower runners,
And the studs attached to the upper and lower runners.

According to this aspect, the three-layer structure studs having the inner studs, which are manufactured in advance in a factory or the like and are modularized, are attached to the upper and lower runners, so that the load bearing wall base material has excellent workability. .. The bearing wall has single or double columns on the left and right, and beams and bases where the heads and lower parts of the left and right columns are joined, but the upper and lower runners are, for example, left and right inside the left and right columns. It has a length that straddles the stud at the end, and the upper and lower runners are fixed to the upper and lower beams.

In addition, one mode of the bearing wall according to the present invention is
The load bearing wall base material,
Columns on the left and right of the load bearing wall base material,
Brace or cross rail which is inserted into the space between the upper and lower inner studs and is attached to the pillar.

According to this aspect, three-layer structure studs having inner studs that are modularized in advance in a factory or the like are attached to the upper and lower runners, and a load bearing element such as a brace is arranged within the thickness of the load bearing wall base material. Since the load bearing elements are attached to the left and right columns, the load bearing wall has excellent workability. Here, the load bearing element is formed by either one of the brace and the cross rail.

In another aspect of the load bearing wall according to the present invention, a dimensional information symbol defining the width dimension and height dimension of the load bearing wall, the number of the studs, the number of the inner studs in each stud, and the installation position are defined. It is characterized in that the stud information symbol or the stud information drawing is linked.

According to this aspect, since the dimensional information of the load bearing wall and the stud information forming the load bearing wall are linked as the information symbol or the information drawing, anyone at the construction site can open the load bearing wall based on the information symbol or the information drawing. It can be easily constructed. The length and inclination of the brace, which is the load bearing element, can be determined by the dimension information symbol that defines the width and height dimensions of the load bearing wall and the stud information symbol or the stud information drawing regarding the number and position of the studs arranged on the load bearing wall. The inner stud installation area where the stud does not interfere with the brace can be set.

More specifically, the specifications of load-bearing elements are set by the dimensional information symbols of the load-bearing walls including the specifications of the left and right columns that form the load-bearing wall (cross-sectional dimensions of columns, whether they are single columns or double columns, etc.). Whether the pillar is a single pillar or a double pillar can be changed depending on the installation location of the load bearing wall, that is, whether it is installed near the wall or at a position where the opening inside the wall is bypassed. For example, there is a drawing that summarizes floor plans and floor plans of each floor of the building, and a collection of legends that cover multiple types of load bearing walls that can be applied, and this drawing includes stud information drawings. obtain. Then, among the walls shown in the floor plan or the like, a set symbol (an example of a stud information symbol) that specifies the bearing wall to be applied is described at the position where the bearing wall is installed. The load bearing walls corresponding to multiple types of set symbols are described in the legend collection, and the legend of the load bearing walls corresponding to each set symbol shows the dimensions of the load bearing walls, and the outer studs that make up the load bearing walls. The specifications of the number and installation position of inner studs, runners, etc., and load bearing elements such as braces (all of these are examples of stud information symbols or stud information drawings). The outer stud and the inner stud may be printed with a set symbol of the bearing wall formed by each member. Further, at the time of factory shipment, the constituent members may be collected for each set symbol and shipped, or at the time of factory shipment, a delivery note for each set symbol may be attached to the constituent member of each set symbol.

As can be understood from the above description, according to the stud, load-bearing wall base material and load-bearing wall of the present invention, a stud that does not require machining in the field, a load-bearing wall base material having the stud, and the load-bearing wall base material are provided. A load bearing wall having wood can be provided.

In the present specification and the drawings, substantially the same components may be denoted by the same reference numerals to omit redundant description.

[Stud, bearing wall base material and bearing wall according to the embodiment]
With reference to Drawing 1 thru/or Drawing 6, an example of a stud, a bearing wall foundation material, and a bearing wall concerning an embodiment is explained. Here, FIG. 1 is an exploded perspective view of an example of a load bearing wall including a stud and a load bearing wall base material according to the embodiment. 2A is a perspective view showing a general portion of the stud, and FIG. 2B is a perspective view showing a runner mounting portion of the stud. Further, FIG. 3 is a view in the direction of arrow III in FIG. 2A, which is a plan view of the stud as seen from above and also shows the interior material. Further, FIG. 4 is a front view of an example of a load bearing wall including a stud and a load bearing wall base material according to the embodiment, and is a diagram illustrating a mounting range of an inner stud.

The load bearing wall 60 shown in FIG. 1 includes a load bearing wall base material 30 formed by four studs 10 and upper and lower runners 20, two sets of double columns 40 on the left and right of the load bearing wall base material 30, and a load bearing wall. Two braces 50 are diagonally attached to the left and right double columns 40 so as to pass through the inside of the thickness of the base material 30. The load-bearing wall 60 shown in the drawing is, for example, a two-story building or a three-story building, which is disposed on the outer or inner wall surface of a lightweight steel-framed detached house or an apartment house. For example, the left and right double columns 40 are bolted to the upper beam 70 formed of the H-section steel of the second floor and the lower beam 80 (see FIG. 4) that also forms the base and is also formed of the H-section steel. By doing so, the bearing wall 60 is attached to the construction surface. The pillar 40 may be a single pillar other than the double pillar, and the load bearing element forming the load bearing wall 60 may be a horizontal rail or the like forming a ladder type load bearing wall other than the brace 50.

Each stud 10 has two outer studs 1 having a height corresponding to the distance between the upper and lower beams, and a plurality of short inner studs 2 interposed between the two outer studs 1. FIG. 1 shows the outer stud 1 of each of the four studs 10 in an exploded manner. Both the outer stud 1 and the inner stud 2 are formed of light-weight steel square studs. The four studs 10 in the example shown in the figure are arranged side by side in sets of two, and two studs 10 of each set are arranged on the sides of the left and right columns 40, respectively.

In the factory, the outer stud 1 is pre-machined to a length corresponding to the distance between the upper and lower beams on each floor, and a screw hole into which a fixing means such as a drill screw, a pan-drill screw or a screw is inserted is pre-machined at a predetermined position. It is a member that does not require cutting or drilling on site.

On the other hand, the inner stud 2 is also a member that is modularized in advance to have a height of 100 mm or the like and is cut and processed into screw holes in the factory. Is an unnecessary member. The inner stud 2 in the illustrated example has a side surface in which two circular holes are formed, as clearly shown in the enlarged view of FIG.

As shown in FIGS. 1 to 3, the inner stud 2 is fixed to the one outer stud 1 by a drill screw 9, and the other outer stud 1 is fixed to the inner stud 2 by a pan drill screw 8. A plurality of short inner studs 2 are interposed between the two outer studs 1, so that a plurality of gaps 12 are formed between the inner studs 2 having a vertical positional relationship. By inserting the brace 50 into the space 12, the brace 50 is disposed within the thickness t1 (see FIG. 2A) of the load-bearing wall base material 30 without interfering with the constituent members of the load-bearing wall base material 30. can do.

As shown in FIGS. 1 and 2B, runner spacers 5 formed by bending flat steel into a substantially U-shape are formed on the side surfaces near the lower end (and near the upper end) of the stud 10 with screws or the like. And is fitted into the runner 20 having a total thickness t2 by the stud 10 and the runner spacer 5.

The brace 50 is configured by combining a flat steel 51 and a turnbuckle 52 having a round steel, and further, welding a flat steel 53 having a bolt hole (not shown) at both ends thereof. The brace 50 is joined to the double column 40 by bolting the flat steel 53 to the gusset plates 41 attached to the upper and lower inner side surfaces so as to project into the construction surface. Since the brace 50 has the turnbuckle 52, the length of the brace 50 can be adjusted by expanding and contracting the turnbuckle 52, and the same type of brace 50 is applied to a plurality of types of load bearing walls having different plane dimensions. be able to. The brace 40 may be in the form of a turnbuckle only, flat steel, square steel pipe, or the like other than the illustrated example. Further, a mode in which a vibration damper such as a laminated rubber, a steel material having a low yield point such as an SN material (rolled steel material for building structure), a LYP material (extremely low yield point steel material), or the like may be interposed. Further, in a so-called ladder-type load bearing wall, a plurality of cross rails formed of steel material having a low yield point is applied as a load bearing element.

As shown in FIG. 3, the pair of studs 10 are arranged so as to be offset from each other in the X direction, which is the thickness direction of the load bearing wall 60. For example, when the bearing wall 60 shown in the drawing is applied to the boundary wall that separates two dwelling units, one set of three layers is used so that vibrations due to the living sound in one dwelling unit are not propagated to the other dwelling unit. The interior material 90 (plaster board or the like) of one dwelling unit is fixed to one outer stud 1 of the stud 10 having a structure with screws 91 or the like, and the other outer stud 1 of the stud 10 having a three-layer structure is provided to the other. The interior material 90 (gypsum board or the like) of the dwelling unit is fixed with screws 91 or the like. In this way, by changing the studs 10 to which the interior material 90 is fixed, it is possible to eliminate the sound propagation between the dwelling units. In addition, in FIG. 3, the brace 40 shown in FIG. 1 is inserted into each of the studs 10 of the three-layer structure arranged side by side at intervals 12 between the inner studs 2 in the vertical relationship.

3 illustrates the case in which the load bearing wall 60 including the stud 10 is a boundary wall, the load bearing wall 60 illustrated in FIGS. 1 and 4 is not limited to the boundary wall, and may be an inner wall such as a partition wall. Besides, it may be applied to the outer wall.

As shown in FIGS. 1 and 4, the upper and lower runners 20 have a length that extends over the studs 10 at the left and right ends of the four runners 20. By being attached, the load bearing wall base material 30 made of lightweight steel is formed. Here, the runner 20 is formed of a channel steel of lightweight steel frame. The upper and lower runners are cut at an intermediate position of the length across the stud 10 at the left and right ends of the four runners, so that interference with an interference member (not shown) at this intermediate position can be avoided. May be.

In addition, as shown in FIG. 4, the floor height is L1, the bearing wall height that is the difference between the floor height L1 and the beam formation L2 is L3, the center-to-center width of the outer corner studs of the left and right double columns 40 is B1, and the core is The center-to-center width of each pair of studs 10 on the left and right, which is the difference between the width B1 and the width 3/4 of the double column 40 and the width of the gusset plate 41 and the like, is B2. The angle of the two braces 50 and the position (height level) at which each brace 50 passes through each stud 10 are set based on the dimension information defining the width dimension and the height dimension of the load bearing wall 60. For example, B1 can be set to a 1P width (1P is 910 mm, for example), B2 can be set to a 0.5P width, and L1 can be set within a range of 2500 mm to 2600 mm.

As shown in FIG. 4, the plane dimension of the bearing wall 60 is set and the position (height level) at which each brace 50 passes each stud 10 is set, so that each stud 10 does not interfere with the brace 50. The installation range of the inner stud 2 is specified as the range of t3, t4, and t5 in order from the top.

In the specified inner stud installation area, a plurality of inner studs 2 are arranged and fixed to the outer stud 1. Here, the stud 10 having a required rigidity is formed by setting the vacant space 12 between the inner studs 2 in the vertical relationship so as to fall within a range of, for example, about 500 mm to 800. In the illustrated example, the inner studs 2 are arranged at the upper and lower ends of the stud 10 and at two central positions, that is, a total of four positions.

As described above, the inner stud 2 is a member that is modularized in advance to have a height of 100 mm or the like in a factory and is cut, and a screw hole is preliminarily processed. Therefore, it is possible to eliminate the need for on-site processing such as measuring and cutting long square studs at the site, and the stud installation time is significantly greater than the installation method in which the inner stud is field processed and then fixed to the outer stud. Can be improved. In addition, in each floor of the building, when there are load bearing walls 60 having various sizes and shapes having different heights and widths, the short inner studs 2 forming the three-layer structure stud 10 are uniformly modularized to a height of 100 mm or the like. By doing so, the complexity at the time of attaching the inner stud 2 in the field is largely eliminated.

Next, with further reference to FIG. 5 and FIG. 6, a stud information symbol or a stud information drawing in which the dimensional information symbol of the bearing wall 60, the number of studs 10 and the number and installation position of the inner studs 2 in the stud 10 are defined. Will be described as being tied to the bearing wall 60, the stud 10, and the like. Here, FIG. 5 is a diagram showing an example of the floor plan of the second floor of the house to which the bearing symbol of the bearing wall is attached, and FIG. 6 is a diagram showing a part of an example of a legend of the bearing wall.

FIG. 5 shows, for example, a floor plan of the second floor of the construction drawings. This construction drawing includes floor plans for each floor, including floor plans and roof plans, as well as floor plans for each floor, and a list of bearing walls applied to the target building is summarized. A legend collection of load bearing walls, some of which are shown in FIG. 6, is included.

As shown in FIG. 5, for example, in the floor plan, a set symbol is assigned to each type of load bearing walls arranged on the inner wall and the outer wall. In FIG. 5, only some of the set symbols on the inner wall are shown. The example set symbols shown in FIG. 5 are [KSS045-2F-2400-910-WW] and [KSS045-2F-2400-910-SW]. Here, [KSS045] means that a light iron stud with a plate thickness of 0.45 mm is used, and [2F] means that it is used on the second floor. [2400] means the ceiling height (bearing wall height) (mm), and [910] means the bearing wall width (mm). Furthermore, [WW] means that the left and right columns are both double columns, and [SW] means that one of the left and right columns is a single column and the other is a double column. .. Whether the pillar is a single pillar or a double pillar can be changed depending on the installation location of the load bearing wall, that is, whether it is installed near the wall or at a position where the opening inside the wall is bypassed. For example, as for the load bearing wall installed near the wall, double columns are applied to one or both of the left and right columns.

As described above, in the construction drawings, the load bearing walls applied to the respective parts on the respective floors are assigned and written with unique set symbols.

Then, in the legend of the load bearing wall shown in FIG. 6, the dimension information (dimension information symbol) of the load bearing wall corresponding to each set symbol is described together with the drawing, and the height position information of the inner stud is also provided. Have been described. In the drawing shown in FIG. 6, a front view of the load bearing wall is shown below, and a plan view of the load bearing wall is shown above. Although illustration is omitted, a set symbol [KSS045-2F-2400-910-WW] or the like is provided at a plurality of positions of each of the outer stud 1 and the inner stud 2, the runner 20, the pillar 40, and the like shown in FIG. 1 and the like. Is preferably printed. Further, at the time of factory shipment, the constituent members may be collected for each set symbol and shipped, or at the time of factory shipment, a delivery note for each set symbol may be attached to the constituent member of each set symbol.

In the legend collection shown in FIG. 6, below the drawing which is the dimensional information symbol of the load bearing wall, the details of the base material and the brace which are the constituent members of the load bearing wall are further described. In the breakdown of the base material shown in FIG. 6, [[1] KKS045-2540-2476] has one outer stud made of a light iron stud with a plate thickness of 0.45 mm and has a cross-sectional dimension of 25 mm×40 mm, 2476 mm, and the right column further describes that the number of sets is 4. Here, the stud has various cross-sectional dimensions such as 45 mm×65 mm (4565) and 40 mm×45 mm (4045). Further, the stud height is different even if the ceiling height is the same due to the difference in beam formation on the upper floor, and even when the ceiling height is 2400 mm, the stud height is 2476 mm (the height of the H-section steel is 250 mm. ), there are various forms such as 2526 mm (the height of H-section steel is 200 mm), 2740 mm (the height from the bottom of the ALC plate on the upper floor and there is no beam).

In FIG. 6, [2] is stud information regarding the other outer stud, and it is described that the number of sets is 4 as well. Further, [3] is stud information on the inner studs, and [100] indicates that the height of the inner studs is modularized to 100 mm, and the number of sets is 16. Also, [4] is information about the runner, [KWR] indicates that it is a lightweight stud runner, [080] indicates that the plate thickness is 0.8 mm, and [40110] indicates channel steel. A C-110×40 is used, and [540] indicates that the length of the runner is 540 mm.

Regarding the brace information, [H3MB2] indicates that the brace is applied to the second floor, and [08V] indicates the specification of the brace.

In this way, since the load bearing walls applied to each part on each floor in the construction drawing are shown as set symbols in the construction drawing, anyone at the construction site can easily and definitely construct each part on each floor. It is possible to specify the form of the load bearing wall to be performed. Then, for example, a component symbol of the load bearing wall that is delivered to the site is printed with a corresponding set symbol of the load bearing wall, and the set symbol is also attached to the delivery note, so that the appropriate component member for each load bearing wall Can be used to construct the bearing wall. At that time, set symbols for each bearing wall are described in the floor plan and floor plan on the construction drawing, and the legend collection includes drawing information of bearing walls corresponding to each set symbol, specifications of the component members and the number of used parts, etc. Since the information of (1) is written and tied, it becomes possible for anyone to construct each bearing wall without fail using the appropriate member that has been brought into the site.

It should be noted that other embodiments in which other constituent elements are combined with the above-described configurations and the like may be combined, and the present invention is not limited to the configurations shown here. This point can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form.
