Description

  The present invention relates to a wooden building foundation and a building structure, and more particularly to a wooden building that can be easily constructed and can be improved in strength.

  There are various types of foundations for wooden buildings, such as solid foundations and cloth foundations. In any foundation, anchor bolts for fixing the foundation and hole-down anchors for attracting pillars are indispensable. For example, the anchor bolts must be installed at positions close to the pillars at both ends of the bearing wall, at places where the foundation is cut, at the joints of the foundation and the upper end of the joint, and at other appropriate positions within 3 meters.

  Anchor bolts are installed by hanging them from a formwork when forming the foundation, placing concrete, and embedding a predetermined length in the concrete.

  If this anchor bolt is not installed properly, the foundation will be displaced from the foundation as it was in the past. In other words, the installation of anchor bolts is a very important task.

  However, the position and height of the anchor bolt must be accurately determined when fixing to a formwork or the like, and the fixing must also be secured. For this reason, the arrangement | work operation | work of an anchor bolt was a complicated operation | work which takes time.

  The foundation top is leveled accurately in millimeters using a leveler after placing concrete. This work is done by piling a leveler after adjusting the height of the head of the nail by, for example, “1 mm up and down” by hitting a nail on the top surface of the concrete after placement by a plurality of people. It is a troublesome work.

  None of the wooden constructions solved the above problems.

  On the other hand, in the foundation of steel construction, there are anchor bolt installation devices and the like embedded in the foundation concrete together with the anchor bolts (see, for example, Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4 below).

  The anchor bolts are disposed in a standing state and are fixed on concrete. The anchor bolt support metal fitting disclosed in Patent Document 1 has a rectangular mounting board and a length above the mounting board. It has a column main body having an anchor bolt mounting plate provided via an adjustable column. The anchor bolt is mounted at four corners of the anchor bolt mounting plate. In other words, the four anchor bolts are configured to be supported by one column body.

  In the support bracket having such a configuration, there is a problem that the anchor bolt does not stand in the vertical direction unless the discarded concrete is horizontal and the anchor bolt mounting plate is not horizontal.

  Also, since the anchor bolt mounting plate is embedded in the foundation, the leveling of the top of the foundation must be performed separately.

  In the installation device disclosed in Patent Document 2, an anchor bolt is set up on a holding tool composed of an upper shape plate, a lower shape plate, and a connecting member for connecting them, and the holding device itself is fixed on the discarded concrete. Fixed on the anchor frame. This anchor frame is composed of four support members projecting on the discarded concrete and two horizontal support members that are horizontally stretched over the upper ends of these support members. By foundation construction, everything except the upper part of the anchor bolt is buried in the foundation.

  Even in the installation apparatus of this Patent Document 2, the leveling of the top of the foundation has to be performed separately. However, since the anchor frame is configured as described above, the leveling of the upper surface of the horizontal support member and the anchor bolt There is an advantage that the position can be adjusted in the vertical direction.

  However, since the horizontal support member is composed of two pieces, it is cumbersome to obtain these horizontal positions, and in addition, the position of the anchor bolt is adjusted by holding the lower plate between the fixing plate and the nut at four locations. Therefore, accurate leveling and position adjustment is not easy.

  The anchor frame disclosed in Patent Document 3 is also fixed on the discarded concrete, and the anchor bolt is integrated. Since the foundation concrete is driven up to the height of the top plate constituting the upper end of the anchor frame, there is an advantage that the leveling operation of the foundation top edge can be simplified as compared with the techniques of Patent Document 1 and Patent Document 2. However, unlike the device disclosed in Patent Document 2, the four anchor bolts are each configured to be self-supporting and connected by the top plate at the upper end, so that the anchor frame is twisted by the pressure when placing concrete. There is a possibility that the installation position, height, direction, etc. of the anchor bolt may be shifted.

  Further, in each of Patent Document 2 and Patent Document 3, a gap is formed between the lower end portion of the apparatus and the discarded concrete, but this gap is a halfway size for compactly packing the concrete. . For this reason, a gap may be formed in the foundation unless the concrete is placed while paying sufficient attention and applying vibration.

  The anchor bolt structure disclosed in Patent Document 4 is a structure in which the four anchor bolts are set up straight so that the upper end height of each anchor bolt can be maintained at a predetermined height. Four anchor bolts that are coaxially screwed together, a rectangular frame-shaped fixing plate that is held between the upper shafts of these anchor bolts, and the length direction of the upper shaft that is disposed on both upper and lower sides of the fixing plate It is the structure which has four sets of nuts which can adjust the position in, and the receiving seat which receives the cone-shaped part formed in the lower end of each anchor bolt. The length of the anchor bolt is determined by the fact that the receiving seat is positioned accurately and the fixing plate is horizontal, so that the four anchor bolts stand vertically and the upper shaft and the lower shaft rotate relative to each other. Can be determined as desired.

However, the anchor bolt structure, similarly to the above-mentioned Patent Document 3, there is no actively support constituting the four anchor member. Since the four anchor bolts are independent and connected by the fixing plate, if the fixing plate is twisted by the pressure when placing concrete, the anchor bolt tilts due to the influence and the displacement occurs. It will be.

  Therefore, the present invention can easily and accurately place the anchor bolts in the foundation work of the wooden building, and can prevent a deviation or a gap from occurring when the concrete is placed.・ The main task is to obtain highly durable wooden buildings.

The means for this is an anchor pack embedded in the foundation, which is a rod-shaped anchor material held in an upright state, a mounting member mounted on the anchor material, and a position surrounding the anchor material in the mounting member A plurality of leg members that support the attachment member, and the attachment member extends through an angle from the insertion hole through which the anchor material is inserted, and the portion having the insertion hole. The free end portion is formed in a plate shape having a plurality of branch portions to which the leg members are attached, and an adjustment means for adjusting the anchor material to a vertically upward posture is provided at the free end portion of the branch portion . Anchor pack for wooden construction. The adjusting means can be configured, for example, by a rotating structure that changes the angle of the leg member or a vertically moving structure that changes the length of the portion below the mounting member of the leg member.

  In other words, when the foundation is formed, the anchor material is placed in a predetermined position in accordance with the core ink drawn on the base concrete or discarded concrete, and then the anchor material is positioned vertically upward by the adjusting means. Adjust so that

The anchor bolt is attached the mounting member, the mounting member is supported by a plurality of leg members at a position surrounding the anchor member. Moreover, the attitude | position of an anchor material can be easily adjusted if an attachment member is inclined using an adjustment means, or a part of attachment member is moved up and down.

  Then, after the anchor pack is installed, the foundation is completed if the anchor pack is buried by placing concrete into a predetermined position.

  During the placement of the concrete, the mounting member supported by the plurality of leg members supports the anchor material, so that it can be supported firmly and can be prevented from tilting. For this reason, the foundation which has the anchor material of a desired position and attitude | position can be formed.

  Here, the following configuration modes can be adopted for the above-described components.

One of the aspects is that a support member that supports the lower end of the leg member is provided, and a fitting portion having a spherical surface is formed at the lower end portion of the leg member via a small diameter portion, and the support member The fitting portion that fits the fitting portion and supports the leg member so that the angle can be changed is formed . The support member may be common to each leg member, may be separate for each leg member, or may be integral with the leg member.

According to this configuration, the installation work can be facilitated by fixing the support member on the base concrete or the discarded concrete when installing the anchor pack. In addition, if the support member is an integral type common to the leg members, the integrity of the anchor pack can be increased and the displacement of the anchor material can be suppressed. Further, if the support member and the attachment member are provided in parallel, the anchor bolt can be erected straight only by being installed on the base concrete or the discarded concrete.

Another aspect is that the support member has a plurality of branch portions in the same manner as the attachment member .

In another aspect, the attachment member has three branch portions .

In another aspect, the two insertion holes of the attachment member are formed and the five branch portions are formed.

  Another means is a wooden building structure in which a frame is formed on a foundation in which the anchor pack for wooden building is embedded. In the present invention, the shaft assembly is composed of members such as through pillars, pipe pillars, studs, girders, beams, torches, foundations, foot firmers, through holes, balustrades, braces, drop boards, and structural plywood. Is.

  In other words, the anchor pack for wooden construction can be easily arranged as described above, the formation of the foundation can be performed easily and quickly, and the strength is also obtained, so that the shaft assembly formed on this foundation is displaced from the foundation. There is nothing and it is supported firmly.

  Still another means is that a shaft is formed on the foundation in which the wooden building anchor pack is embedded, and the lower end portion of the column of the shaft is connected to the anchor material of the wooden building anchor pack. It is a wooden construction structure.

  In other words, the anchor pack for wooden construction can be easily arranged as described above, the formation of the foundation can be performed easily and quickly, and the strength is also obtained, so that the shaft assembly formed on this foundation is displaced from the foundation. There is nothing and it is supported firmly. And since the lower end part of the column material of a frame is connected with the anchor material of the anchor pack for wooden buildings, the column material can be directly connected to the foundation. In addition, the anchor member directly connected to the column member is held by a mounting member or the like embedded in the foundation so that it is not displaced or pulled out, and the portion of the foundation has high strength both in compression and tension. For this reason, higher strength and higher durability can be achieved than in the case of supporting with anchor bolts whose lower end portions are bent as before. And, since the pillar material is directly connected to the high-strength anchor material as described above, it is possible to prevent the pillar material from causing mortise from the base, and to obtain a wooden building that is resistant to earthquakes. .

  As described above, according to the present invention, an anchor pack for wooden building in which an accurate arrangement of anchor materials is easy can be obtained. In addition, since the anchor material is supported by the mounting member and the leg member, the base material is not misaligned by placing concrete, and a foundation with high accuracy and strength is obtained. In addition, the construction can be simplified and the construction period can be shortened.

  Since such a high-strength foundation can be obtained, a wooden structure that can stably support the frame and is strong against earthquakes can be obtained.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a sectional view showing the structure of a wooden building foundation and a column base portion. As shown in FIG. 1, an anchor pack 21 is embedded in the foundation 11 and anchor bolts held by the anchor pack 21 are shown. The column member 52 of the shaft set 51 is directly connected to the shaft 22.

  The directly connected column member 52 is preferably a through column 52a (see FIG. 2). Further, the column member 52b may be an important column member for supporting the load by connecting the end portion of the horizontal member 53 to the upper end portion thereof like the through column instead of the through column 52a.

  That is, the anchor pack 21 is provided at a position where the column member 52 directly connected as described above is built in the shaft set 51 illustrated in FIG.

  As shown in FIG. 3, the anchor pack 21 is grounded on the base concrete 12 of the foundation 11 and embedded in the rising foundation 13. In the illustrated example, a solid foundation is shown, but another form of foundation may be used.

  FIG. 4 is an exploded perspective view showing the structure of the anchor pack 21, which has a frame body 23 and one anchor bolt 22.

  The frame body 23 is parallel to the lower plate 24 with respect to the lower plate 24 that contacts the upper surface of the base concrete 12, four columns 25 erected from the lower plate 24, and the upper ends of these columns 25. And an upper plate 26 whose upper surface is positioned at the same height as the top end of the rising base 13 to be formed later.

  The lower plate 24 has a rectangular plate shape and has two window portions 27 penetrating in the thickness direction on the inner side excluding the central portion. At the four corners, cylindrical screwed portions 29 having screw portions to which the bolts 28 can be screwed are provided so that the horizontal on the base concrete 12 can be brought out by screwing the bolts 28.

  Further, a notch 30 as a mark is provided at a position in the middle of each side of the lower plate 24 so that the center position of the lower plate 24 can be easily grounded to a predetermined position on the base concrete 12.

  As shown in FIG. 5, a holding recess 31 that receives and holds the lower end of the anchor bolt 22 is formed at the center position on the upper surface of the lower plate 24. The holding recess 31 is formed in a cylindrical shape, and an internal thread 31 a is formed on the inner peripheral surface thereof to engage with the external thread 22 a formed at the lower end of the anchor bolt 22.

  Further, through holes 32 are provided at appropriate portions in the lower plate 24, and fixing members 33 such as nails for fixing to the base concrete 12 can be attached.

  Further, an attachment portion 34 for attaching the support column 25 is erected on the upper surface, and the lower end portion of the support column 25 can be detachably fixed. In the figure, reference numeral 35 denotes a fixing screw. Since the support column 25 can be attached / detached, that is, the anchor pack 21 can be disassembled, if it is assembled at the site, it is possible to reduce the cost for carrying in the site and to prevent breakage during transportation. Moreover, simplification of a structural member can also be achieved.

  The support column 25 is made of an angle material and is formed to have a predetermined length corresponding to the height of the formed rising base 13, and a female screw 36 for screwing the fixing screw 35 into both upper and lower ends. Is formed. In addition to the angle member, a solid or hollow rod-like body such as a circular cross section or a square shape can also be used.

  The upper plate 26 is formed in substantially the same form as the lower plate 24. However, an insertion hole 37 for holding an anchor bolt is formed at a position facing the holding recess 31 without having the threaded portion 29, the through hole 32, and the holding recess 31.

  The anchor bolt 22 has a first male screw 22a that contributes to retaining at the lower end portion thereof, and a second male screw 22b that contributes to retaining and fixing the column material upward from a portion corresponding to the insertion hole 37. Have The second male screw 22b holds two nuts 38, 39, and when the anchor bolt 22 is fixed to the frame body 23, the nut 38, 39 sandwiches the periphery of the insertion hole 37 of the upper plate 26 vertically. So, it will be firmly integrated.

  The frame body 23 is preferably made of metal. In this case, the frame body 23 may be plated, or may be made of a synthetic resin.

  The frame body 23 may be provided with an adjuster structure that adjusts or changes the height of the frame body 23.

  FIG. 6 shows an adjuster structure for fine adjustment that can be provided between the lower plate 24 and the support column 25 or between the support column 25 and the upper plate 26. A long hole 40 is formed in the attachment portion 34 of the plates 24 and 26. Is provided.

  FIG. 7 shows an adjuster structure for changing the height provided in the support column 25. The support column 25 is vertically divided into two, and a long hole 41 is formed in one of the support carriers 25a. The length can be changed by fixing the overlapping length of the column supports 25a and 25b with the screw member 42 held by the other column support 25b.

The anchor pack 21 configured as described above is used as follows after the anchor bolts 22 are inserted and fixed to the frame body 23 from above.
In other words, after the base concrete 12 is formed, the base concrete 12 is installed at a predetermined portion of the portions forming the rising foundation 13. The installation is grounded in accordance with the core ink formed on the base concrete 12, and the bolts 28 to the threaded portions 29 of the lower plate 24 so that the lower plate 24 and the upper plate 26 are horizontal at a predetermined height. After that, the fixing member 33 is driven into the base concrete 12 from the through hole 32 and is fixed. A hole-in anchor or the like may be fixed to the base concrete 12 and a bolt 28 may be screwed and fixed to the hole-in anchor.

  Subsequently, appropriate placement is performed, a formwork is assembled, concrete is placed, and the rising foundation 13 is formed. The top end 13a of the rising base 13 is precisely performed by pouring a leveler. At this time, since the upper surface of the upper plate 26 of the anchor pack 21 indicates the level of the top end 13a, the leveler is poured into the upper surface of the upper plate 26. Just do it. That is, the leveling for forming the top end 13a can be automatically performed when the anchor pack 21 is installed, and it is not necessary to separately perform the leveling work, so that the construction is simple. For this reason, it is possible to simplify the foundation work and shorten the latter period.

  After the rising foundation 13 is formed in this way, the nut 39 located on the upper side of the upper plate 26 is removed from the nuts screwed to the anchor bolts 22 to form the shaft set 51.

  Next, the column base metal 61 suitable for erection of the column material 52 with respect to the anchor bolt 22 held by the anchor pack 21 when the shaft set 51 is formed will be described.

  As shown in FIG. 8, the column base 61 is for connecting the column member 52 of the shaft set 51 to the anchor bolt 22 of the anchor pack 21 on the same axis, and is composed of one member.

  That is, as shown in FIG. 9, a cylindrical insertion portion 62 that is inserted and fixed to the column member 52 from the lower end thereof, and is formed on the outer periphery of the lower end of the insertion portion 62, and the lower end surface of the column member 52 is It has a bowl-shaped receiving portion 63 for receiving, and an annular plate portion 64 formed on the inner periphery of the insertion portion 62 and formed with a fool hole 64 a for receiving insertion of the anchor bolt 22.

  The insertion portion 62 has a through hole 62a into which a bolt or drift pin is inserted after being fixed to the column member 52 from below, and an upper end 62b is opened.

  The receiving portion 63 and the annular plate portion 64 are integral and form a circular shape in plan view. In other words, a circular plate member having the above-described hole 64 a having a diameter smaller than the inner diameter of the insertion portion 62 is fixed to the lower end of the cylindrical insertion portion 62.

  Four mark notches 63a are formed at equal intervals on the outer peripheral edge of the receiving portion 63, and the two notches 63a facing each other are set in the same direction as the through hole 62a.

  The column base 61 is provided with a position adjusting nut 65, a fixing nut 66, and washers 67, 68 overlapping therewith. The position adjusting nut 65 is for screwing into the anchor bolt 22 to determine the position of the column base 61 in the vertical (vertical) direction on the anchor bolt 22, and is provided with the washer 67 on the upper surface side thereof. ing. The washer 67 is a plate having a through-hole having a size through which the anchor bolt 22 passes, and the washer 67 receives the lower surface of the annular plate portion 64 of the column base metal 61 as shown in FIG.

  The fixing nut 66 is for tightening the annular plate portion 64 of the column base 61 supported by the position adjusting nut 65 and the washer 67. A washer 68 stacked under the fixing nut 66 is formed under the large diameter portion 68a and a large diameter portion 68a having a size that fits in the insertion portion 62 so as to be fitted to the annular plate portion 64 from above. Then, a long hole 68c for position correction is formed in a plate shape composed of a small-diameter portion 68b having a size that can fit in the fool hole 64a. The thickness of the small diameter portion 68 b is set to be thinner than the thickness of the annular plate portion 64.

  That is, prior to the work of installing the column member 52 on the anchor bolt 22, the position adjusting nut 65 is screwed onto the anchor bolt 22 and the washer 67 is set. The position adjusting nut 65 is rotated and adjusted so that the upper surface of the receiving portion 63 is positioned at a predetermined height (see the one-dot chain line in FIG. 10). Subsequently, the fixing nut 66 is screwed into the anchor bolt 22 through the washer 68 from above. Then, as shown in FIG. 11, the horizontal position of the column base 61 is adjusted using the notch 63 a and tightened with the fixing nut 66.

  That is, in the same way as leveling is performed prior to the formation of the rising foundation 13, leveling of the lower end surface of the column material 52, horizontal position adjustment, and orientation adjustment can be performed prior to the column material 52 being built. . In other words, the leveling can be easily performed at least twice through the building method from the foundation work, and in particular, since the column base metal 61 is used, the position adjustment of the column material 52 prior to the installation of the column material 52 is accurate. Moreover, it can be done easily.

  When the column base 61 is fixed, the state as shown in FIG. 12 is obtained, so that the column member 52 is built after attaching an appropriate foundation packing 69 or the like as shown in FIG. Subsequently, necessary work such as fixing the base 54 is performed. In the figure, reference numeral 70 denotes an anchor bolt that has been mounted as usual.

  In place of the basic packing 69, an anchor bolt or the like can be concealed by filling an appropriate filler after the base 54 is fixed.

  The anchor pack 21 is configured as described above, and the anchor bolt 22 can be disposed at a predetermined position simply by arranging the anchor pack 21 by aligning the notch with the core corner marked on the base concrete 12. In addition, since the upper plate 26 is parallel to the lower plate 24 and the upper surface of the upper plate 26 rises and is positioned at the same height as the top end 13a of the foundation 13, the upper plate 26 is grounded and fixed so that the lower plate 24 becomes horizontal. Then, the level of the top end 13a of the rising base 13 can be automatically set.

  Further, during the placement of the concrete, the lower plate 24, the support column 25, and the upper plate 26 form a single frame and hold the anchor bolts 22, so that the anchor pack 21 is not twisted and deformed. The anchor bolt 22 can be installed in the state at the time of arrangement. In addition, since the lower plate 24 is basically grounded on the base concrete 12, it is difficult to form a halfway gap where the concrete cannot be packed, and a solid rising foundation 13 can be formed.

  In addition, the anchor bolt 22 is held at two locations, the lower end portion and the upper portion, and is fixed by screws. Therefore, the anchor bolt 22 is not displaced in the horizontal direction, and strength against pulling is obtained. Further, the lower end of the anchor bolt 22 is received by the lower plate 24 and can strongly support the load from above.

  That is, the anchor pack 21 cooperates with the concrete in the rising foundation 13 to form a rising foundation that is strong against tension as well as being compressed.

  The foundation 11 constructed by burying such anchor packs 21 has high strength, and the wooden construction in which the shaft group 51 is constructed using the anchor bolts 22 is a structure (floor group) on the foundation 11. And the shaft assembly) are not displaced from the foundation 11 and are firmly supported.

  In addition, since the column member 52 is connected on the same axis as the anchor bolt 22 using the column base hardware 61 as described above, the column member 52 can be directly connected to the foundation 11, and the hole down hardware can be attached. Even if it is not provided separately, it will be a high-strength, high-endurance wooden structure that is resistant to earthquakes, which can prevent mortars from escaping from the base.

  Furthermore, if the column base metal 61 as described above is used to build the column material 52, it is possible to easily perform accurate leveling and positioning even in the building method, in addition to performing high-accuracy leveling in the foundation work. In addition, the height and position of the column member 52 can be made accurate. For this reason, it is possible to obtain a highly accurate wooden structure without distortion, which greatly contributes to improvement in strength and durability.

  The anchor pack 21 can be used in a simple operation of inserting and fixing the anchor bolt 22 to the frame body 23. The structure is simple and has a small number of parts, and is a compact and easy-to-handle anchor pack 21 that is optimal for a foundation for a wooden building having a width and height smaller than those for a steel building foundation.

  Other forms will be described with reference to FIGS. In the description, the same or equivalent parts as those in the above configuration are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 13 is a perspective view of the anchor pack 21 holding the two anchor bolts 22 and 22. The lower plate 24 and the upper plate 26 are formed in a rectangular plate shape having a length necessary for holding the two anchor bolts 22, and have a window portion 27 at the center. And the anchor bolts 22 and 22 are hold | maintained to the both ends of a length direction similarly to the case of the said structure.
