Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to architectural hardware often used in wooden framed house and wooden framed wall house.

[0002]

[Prior art]

 A structure in which one long member (for example, a base) and the end of the other long member (for example, a pillar) are abutted and assembled is often used in a wooden framed construction method or a wooden framed wall construction method. In these wooden houses, in addition to the connection between the foundation and the base, the connection between the members is important, such as the connection between the base and the column, the connection between the column and the beam or the bracing, and many building hardware. Things are used. For example, a pull-in hardware 5 as shown in FIGS. 15 and 16 has been used for the connection between the base and the column or the connection between the upper and lower tube columns sandwiching the column. Reference numeral 1 is a cloth foundation, reference numerals 2a and 2b are bases, reference numeral 3 is an anchor bolt, and reference numeral 4 is a through column or a tube column.

Each of the pulling hardwares 5 includes a back plate 6 and a penetrating engagement portion 7. The back plate 6 is provided with bolts 8 (FIG. 11), nails (including screw nails) or It is fixed with a hold-down screw (long screw with a head) 9, and a pulling bolt 10 is engaged with the penetration engaging portion 7 with a nut 11. The pulling bolt 10 has a lower part embedded in the fabric base 1 and fixed in advance. Then, by tightening the nut 11, the column 4 is drawn to the bases 2a and 2b to be tightly connected. The maximum pull-out strength due to binding is 30 to 60 KN.

[0004] Bolts, nails, or screws for fixing the attracting hardware 5 to the pillar 4 are properly used depending on the use conditions such as the condition of the pillar 4 (such as a core holding material) and work procedures, and the number of the bolts also increases or decreases depending on the strength. are doing. For example, when fixing with bolts, basically two bolts are used to achieve a pull-out strength of 10 KN, and based on this, the bolts are increased by one each time the pull-out strength needs to be increased by 5 KN. Adjust the number of nails and screws in the same way.

On the other hand, the metal fittings 5 themselves are made of a general-purpose steel plate (6.0 mm or 4.5 mm in thickness) for building hardware, and according to the means of arc welding usually used for joining parts, Since the pull-out resistance exceeds 30 KN in both structural and structural terms, in order to use this drawn metal for general purposes, a plurality of bolts, nails or screws corresponding to 30 KN must be inserted through the back plate 6. Holes (fixing holes) are formed from the beginning. For this reason, when using such a drawn metal piece at a place where a pull-out strength lower than 25 KN is sufficient, such as 15 KN, for example, it is necessary to select and use a plurality or a large number of fixing holes. Become.

[0006] The selection is made by the operator on site, but there is no means for appropriately selecting such fixing holes in the conventional pulling hardware 5, and all the fixing holes are blindly blinded. Used or conversely, the required number of fixing holes are not used. In particular, when using a large number of screws, etc., it is necessary to secure the back plate 6 so that it will not be removed, so that it can be fixed efficiently. There is. Such a situation is the same in the case of bracing plates or beam receiving members fixed by using a large number of nails or screws, which is common to building hardware in general. In some cases, increasing the length of the fixtures used, such as nails, may reduce the number of strikes required for fixation.

[0007]

[Problems to be solved by the invention]

 The idea is that a large number of fixing holes provided for general purpose and common use in building hardware should be appropriately selected and used according to the required fixing force (pulling strength for pulling hardware). As an issue.

[0008]

[Means for Solving the Problems] A plurality of fixing holes formed in architectural hardware are provided with identification marks to facilitate selection of the fixing holes according to use conditions. This eliminates confusion in on-site work and prevents unnecessary work and lack of fixing force. In the case of a pulling hardware having a back plate portion and a through-engagement portion of a pulling bolt, a plurality of fixing holes for fixing with a nail or a screw are formed in the back plate portion. The number shall be determined in consideration of the strength of one nail or screw, the strength of the material of the drawn metal and the structural strength, and shall correspond to the maximum pull-out strength that this metal can exhibit. Then, an identification mark indicating each case is attached to a fixing hole to be selected when the fixing hole is used with the pull-out strength or less. That is, as the maximum pull-out strength of 25 KN, for example, when the pull-out strength is 15 KN, the fixing hole specified for this pull-out strength is selected, and when the pull-out strength is 10 KN, the fixing hole specified for this strength is selected and used. Mark for identification.

A fixing hole selected and used in accordance with a required pull-out strength (set pull-out strength) may be provided with a numeral indicating the pull-out strength as an identification mark. For example, a numeral “15” is assigned to a fixing hole to be selected at 15 KN. The number of fixing holes selected is not necessarily proportional to the magnitude of the pull-out strength. This is because the safety of the relationship between the strength of the pull-out resistance and the fixed state of the drawn hardware and the arrangement of the fixing holes in order to maintain the fixed state stably are taken into consideration. For example, at 10 KN, 6 fixing holes are used, but at 15 KN, 8 fixing holes are used.

The type of the identification mark does not matter. However, the fixing holes that must be selected according to the set fixing force (required fixing strength, pull-out strength, etc.) must be easily and reliably identified by the operator. Further, the selection of the fixing hole is not limited to a number, but may be of a type such as using nails of different lengths. If there are six fixing holes for nails or screws in the attracting hardware, three should be distributed to both ends of the back plate in consideration of the balance of the force for fixing the attracting hardware to the pillar. Sometimes.

[0011]

[Embodiment of the invention]

 The drawing hardware 5 of FIG. 1 is a first embodiment, and includes a back plate portion 6 and a penetration engaging portion 7. The back plate 6 is basically a rectangular flat steel plate having a thickness of 6.0 mm, a width of 45 mm, and a height of 240 mm, and is folded up so that both sides of the lower half thereof are turned up from the back side to the front side. Of the through-engaging portion 7 is fixed by welding. The penetrating engaging portion 7 is a rectangular flat steel plate having a thickness of 4.5 mm and is bent into a U-shape with slightly longer hem portions on both sides. The penetrating engaging portion 7 has a height of 60 mm, an outer width of 26 mm, and a front and rear outer dimension of 45 mm. .

The upper half 12 of the back plate 6 has twelve fixing holes 13 formed therein. Six fixing holes 13 are arranged at each end of the upper half part 12, three at each end, and are arranged so that the distance between adjacent fixing holes as a whole is as equal as possible. . The lower portion 14 of the back plate 6, that is, the portion below the portion forming the through-engagement portion 7, becomes wider again, and serves as a penetration resistance portion.

As shown in FIG. 1, each of the large number of fixing holes 13 is provided with a number corresponding to the set pull-out strength and used as an identification mark for selective use. The six fixing holes 13 divided into three at both ends are provided with identification marks "10", and when the pull-in hardware 5 is used at a place where the pull-out strength is 10KN, the six fixing holes 13 are used. This indicates that the hole 13 should be selected.

Similarly, when the pulling hardware 5 is used at a place where the pullout strength 15 KN is set, eight pieces are selected by adding the identification mark “15” to the preceding six pieces. Hereinafter, the identification mark “20” and the identification mark “25” are used by increasing them by two. When all the fixing holes 13 are used, the pull-out metal member 5 can be used up to a portion where the pull-out strength is set to 25 KN. As described above, the fixing holes 13 are used progressively, but the explanation to the operator is simple, and the confirmation of the identification mark is simple and clear.

FIG. 2 shows a state in which a hexagonal head hole down screw 15 is used as a fixing tool for fixing the attracting hardware 5, and one hexagonal head hole down screw 15 is connected to the fixing hole 13. It is illustrated by being inserted into one. FIG. 3 shows an example of use, in which a wooden frame construction method is used, in which a pulling hardware 5 is fixed to a front surface of a pillar 4 with a hexagonal head hole down screw 15 and an upper end of a pulling bolt 10 is attached thereto. Are engaged with the nut 11, and the nut 11 is tightened to tighten the column 4 to the bases 2a and 2b. The base of the pulling bolt 10 is embedded and fixed in the cloth foundation 1.

FIG. 4 shows a case of the framed wall construction method. Similarly, a drawing hardware 5 is fixed to the front of the column 4 with a hexagonal head hole down screw 15, and an upper end of the drawing bolt 10 is fixed to the nut 11 with a nut 11. The column 4 is engaged with the bases 2a and 2b by tightening the nut 11. The pulling bolt 10 is short and is connected to the base side via a nut 16 with a washer whose lower end is screwed to the upper end of the anchor 3. The nut with washer 16 has a structure in which a washer is fixed to one end of a high nut in principle, and a female screw is formed through the nut. The nut with washer is screwed to the upper end of the anchor 3 to fix the base 2a to the cloth foundation 1. At this time, a blade is provided on the lower surface of the washer, and when it is rotated by a tool at the time of mounting, it sinks down while digging and the upper surface can be made the same as the upper surface of the base 2a.

FIGS. 5 to 7 show another example of the identification mark. In FIG. 5, the fixing holes 13 to be further selected are surrounded by a frame with the set pull-out strength increased by one step. Is provided with one number (corresponding to the pull-out strength). The number of numbers is reduced, and the operator is not bothered when selecting the fixing holes 13 and the number of errors is reduced. The reason why the six pieces corresponding to 10KN are not enclosed in a frame is that this is a basic thing as an initial proof stress and is always used.

FIG. 6 is similar, but the increase is connected by a line instead of the frame. Also, in FIG. 7, although the frame is surrounded by a frame, the identification display is familiar, such as “second” or “third”. In this case, for example, it is necessary to explain, for example, "When using it in a place with a pull-out strength of 15 KN, use the second one." However, once used, it can be used without further explanation. In this way, various user-friendly identification marks can be adopted.

FIGS. 8 and 10 illustrate a pulling hardware 17 having only a selected fixing hole, so to speak, dedicated to a set pull-out strength. FIG. 8 shows an example of 10 KN, in which a large identification mark “10” is placed at the center of the upper half 12 of the back plate 6. Since there is no other fixing hole 13, the pulling hardware 5 is exclusively for 10 KN. FIG. 9 shows an arrangement of a hole-down screw 16 with a hexagonal head, which is the fixing tool. FIG. 10 is also the same, and illustrates an example in which 15 KN is dedicated to a pull-out strength part.

The bracing plate 18 shown in FIG. 11 is a second embodiment in which a large number (25) of fixing holes 13 are formed. These fixing holes 13 are for inserting nails or screws for fixing the bracing plate 18 across the column 4, the base 2a and the bracing 19 (FIGS. 12 and 13). These twenty-five holes are provided with a column group 20 (six) for fixing to the column 4 and a horizontal member group 21 (six) for fixing to the horizontal member such as the base 2a. The gradient (large) group 22 (8 pieces) when fixed and the gradient (small) group 23 (8 pieces) for fixing to a stair with a small slope can be classified. Small) group 23 shares the central three.

As shown in FIG. 11, the gradient (large) group 22 and the gradient (small) group 23 surround these frames, and “Gradient (Large)” and “Gradient (Small)” are provided in the respective frames. The identification mark is attached to the letter. Such an identification mark is clear and can be reliably distinguished according to the use condition. Therefore, at the site, the worker nails to an extra location, or the nail is bent at the end of the brace 19 in the width direction. Inconveniences such as damage to the bracing material due to being located in the part can be eliminated.

The beam receiving hardware 24 shown in FIG. 14 is a third embodiment, and supports an end of the other horizontal member 26 that abuts against the side surface of one horizontal member 25. The beam receiving hardware 24 is formed integrally with a fixing surface portion 27 for fixing to one side surface of the horizontal member 25 and a U-shaped receiving portion 28 for receiving an end of the other horizontal member 26. A fixing hole 13 for inserting a nail or a screw into the surface portion 27 and the receiving portion 28 is provided.

In this embodiment, 14 fixing holes 13 are formed in each of the fixing surface portions 27. When fixing with the thick nail ZN65 (Z mark display hardware), all 14 are used, and the thick nail ZN90 is used. It is designed so that the required fixing force can be exerted by selecting nine of them when using. An identification mark corresponding to the type of nail used is attached. That is, the fixing holes 13 to be selected when using the thick nail ZN90 are framed as a group, and the number “90” is put therein to distinguish them from the others so as not to cause confusion in the field work. I have.

Although the embodiment has been described above, the present invention is not limited to the pulling hardware, the bracing plate, or the beam receiving hardware. The form and structure of the pull metal member 5 having the back plate portion 6 and the through engagement portion 7 are not limited to those illustrated. The arrangement of the fixing holes 13 is also an example. Furthermore, screw nails can be used for the fixing device, and are not limited to hexagon head hole down screws and thick nails.

[0025]

[Effect of the invention]

 At the site of a wooden house building, it is unlikely that work such as nailing and screwing of hardware will be confused. Precise work with proper nailing and screwing can be expected. Accidents that damage the lumber, such as nailing the edges of the lumber, can be prevented. The same pulling hardware can be used in places where the required pull-out strength (design pull-out strength) is different by selecting the fixing holes. At that time, the fixing holes required for the set pull-out strength can be easily identified and used. Fixing of the attracting hardware to the pillar is stable, and safety is high.
