Description

  The present invention relates to a fixing bracket used for construction of a building base material and a building base material fixing structure using the fixing bracket.

  Conventionally, mortar finishing is generally performed as a method for finishing an outer wall of a building, but there is construction using an architectural base material as one that improves the workability of a series of operations. For example, a building base material is a surface of a base material such as a wood-based material with a mixture layer mainly composed of inorganic binder and asphalt. Directly or via an air-receiving material, the caulking material is filled in the joint joint between the building base materials, and a net-shaped joint covering material is stretched across the joint caulking material, such as nails and staples It is known that after the building base material and joint covering material are fixed to the base structure material with the above-mentioned fixing tool, mortar is directly applied thereon to perform exterior finishing.

Joint covering materials include inorganic or organic fibers such as glass fibers, carbon fibers, and polypropylene fibers, metal fibers such as iron, steel, copper, and aluminum, cold woven fibers, lath nets, metal laths, etc. The cotton-like net is used. In general, the joint covering material is separate from the architectural base material. However, in Patent Document 1 below, the joint covering material is provided so that the joint covering material protrudes from the piece of the architectural base material. ing
Japanese Utility Model Publication No. 63-101632

  In the prior art, in exterior wall finishing using a building base material, by applying a net-like joint covering material to the joint joint portion between the building base materials, the expansion and contraction accompanying the moisture absorption and drying of the building base material, Although the mortar coated on it is prevented from cracking, the building base material and the base structure material are only fixed with fixing tools such as nails and staples. The movement of the building base material due to movement, earthquakes, ground vibrations, etc. could not be suppressed with the fixture alone, and cracks could not be completely prevented.

  Since the above-mentioned Patent Document 1 uses a material in which the joint covering material is integrated with the building base material, it can bring about the advantage that the construction labor is simplified, but it is a solution to the prevention of cracking. is not.

  Therefore, the present invention solves the above-described problems in the prior art, and more effectively generates cracks in the mortar coated on the joint joint between the building base materials in the exterior wall finishing using the building base material. The purpose is to prevent.

  In order to achieve this object, the present invention according to claim 1 is a base material fixing bracket for a building used for a joint part to fix the building base materials in a butted state. A standing part that rises at a predetermined angle from the part, and can extend and bend at a predetermined angle from the upper end of the standing part toward at least one side, and a sharp locking claw from its tip toward the base part It is possible to fix the building base material inserted into the space surrounded by the base part, the standing part and the fixing part with the locking claw at the tip of the fixing part. It is characterized by.

  The architectural base material fixing bracket of the present invention is formed from a metal plate such as aluminum, stainless steel, or steel plate. The thickness is arbitrary and is generally about 0.3 to 2.5 mm, but 1.0 to 2.0 mm for an aluminum plate, 0.5 to 1.0 mm for a stainless steel plate, and a steel plate. When the thickness is about 0.35 to 1.0 mm, the fixture can be driven through by hand punching using a hammer or mechanical punching using an air tucker or the like. There is no need to form holes. In addition, by using a sufficiently long fixture such as a nail, the fixing bracket can be fixed to the base structure material (columns, studs, ventilation receptacles, etc.) over the base material for construction. The fixing of the building base material and the fixing bracket to the building base material may be performed simultaneously.

  The length of the fixture is arbitrarily determined within a range of 30 to 3500 mm, for example. It is possible to place long fixing brackets without any gaps and fix building base materials continuously, or short fixing brackets to be spaced only at necessary parts and intermittent building base materials. It may be fixed to.

  The fixing bracket includes a base portion, an upright portion, and a fixing portion with a locking claw, and is integrally formed. A pair of integrally formed products in which the fixing portions with pawls extend obliquely in an arbitrary direction may be integrated by joining them back to back by welding / bonding or other arbitrary means.

  A base part contacts these in the state clamped between the base material for construction and the base structure material in the attachment state. A fixing hole for inserting a fixing tool such as a nail can be formed through the base portion at an arbitrary interval and at an arbitrary interval. Although the width | variety of a base | substrate part is arbitrary, when forming a fixture hole, it is necessary to have sufficient width for it. The width of the base portion may be smaller than the width (extending length) of the fixed portion. The base part is generally formed on a flat plate as a whole, but is formed in an L shape having two substrate surfaces orthogonal to each other when it is used in a protruding corner part or an entering corner part.

  The standing portion rises at a predetermined angle from the base portion, and in the mounted state, comes into contact with the butting surface (the end surface) of the building base material or substantially contacts the position close to the end surface. The length (height) of the standing portion corresponds to the thickness of the building base material to be fixed with the fixing bracket, and for example, three types of buildings having different thicknesses such as 7.5 mm, 9 mm, and 12 mm. If it is used for fixing to a base material for use, three types of fixing brackets having standing portions having a length corresponding to each thickness are prepared. The standing part is generally formed so as to rise substantially vertically from the center in the width direction of the base part or from one side edge to give a vertical surface. It is formed so as to stand up at an arbitrary angle in response. The standing portion is preferably formed continuously along the longitudinal direction of the base portion, but may be formed intermittently at intervals.

  A waterproof member such as a caulking material or a backup material can be provided at the center of the standing portion or at the corner portion between the standing portion and the base portion over the entire length in the longitudinal direction of the fixing bracket. By providing the waterproof member in this manner, the waterproof member is appropriately deformed when the architectural base material is inserted into the fixing bracket, so that the fixing bracket and the bottom and / or the back surface of the architectural base material are interposed. It will be filled without gaps, and even if water enters between the fixing bracket and the building base material, water can be prevented from entering the base structure material located on the back side of the building base material. , Do not rot the underlying structural material.

  It is preferable that the standing part is formed so as to rise from the substantially center of the base part, and thereby two building base materials can be fixed in a state of being attached to both sides of the standing part of one fixing bracket. It is also within the scope of the present invention to provide a standing portion so as to rise substantially vertically from one side edge of the base portion. The fixing bracket having such a shape can be used such that the standing portion is positioned at the end portion of the wall surface and the end face of the building base material is brought into contact with one side thereof.

  The fixed part extends at a predetermined angle from the upper end of the standing part toward at least one side and can be bent, and in a mounted state, the fixing part is bent substantially perpendicular to the standing part. Touch the surface of the building base material. The skew angle of the fixed part is about 100 degrees or more with respect to the standing part. When the skew angle of the fixed portion is less than 100 degrees, the end portion of the building base material is inserted into the space surrounded by the base portion, the standing portion, and the fixed portion. The locking claw comes into contact with the surface side of the sheet, making it impossible or difficult to insert.

  It is preferable that the locking claw bent from the front end of the fixing portion has a protruding length of about 3 to 8 mm. If the protruding length of the locking claw is less than 3 mm, the fixing action is insufficient even if it is driven into the surface of the building base material. Conversely, if the protruding length exceeds 8 mm, the fixing action on the building base material is Although it is fully demonstrated, it becomes difficult to drive the locking claw and the workability deteriorates.

  The fixing portion may be formed continuously along the longitudinal direction of the fixing bracket. However, in consideration of workability when the locking claw is driven into the surface of the building base material, a predetermined interval is provided in each oblique direction. It is preferable to be provided intermittently.

  In the case of a fixture that is used to abut the end of two building base materials and fix these two building base materials, the fixing portion is formed in the left and right direction from the tip of the standing portion. . In this case, the fixed portion that is skewed to one side and the fixed portion that is skewed to the other may be formed alternately, or a pair of fixed portions that are skewed in the left and right directions from the same position at the tip of the standing portion is formed. May be.

  Since fixtures such as nails are driven into the four peripheral edges of the building base material at a pitch of 100 to 150 mm, it is preferable to determine the installation pattern of the fixed portions so that there is no fixed portion at the driving position of the fixture. Of course, if the fixture can be easily penetrated through the fixed portion and the base portion by hand or mechanical punching by appropriately selecting the material and thickness of the fixture as described above, it depends on the driving position of the fixture. The fixing portion can be arbitrarily provided.

  The present invention according to claim 2 is capable of extending and bending at a predetermined angle from the base part, the standing part rising from the base part at a predetermined angle, and at least one side from the upper end of the vertical part. In a space surrounded by the base part, the standing part and the fixing part of the fixing metal part, using a fixing metal part having a fixing part in which a sharp locking claw is bent toward the base part from the tip. The construction base material is inserted into the surface, and a locking claw at the tip of the fixing portion is engaged with the surface of the construction base material to fix the construction base material, and the construction base material is fixed to the base structure material. It is a base material fixing structure for building.

  According to a third aspect of the present invention, in the architectural base material fixing structure according to the second aspect, the base material and / or the fixing part of the fixing metal are penetrated from the surface of the architectural base material into the base structural material. By the fixing tool, the fixing bracket is fixed to the building base material, and at the same time, the building base material is fixed to the base structure material.

  The building base material fixing structure according to the present invention is obtained by fixing the building base material to the base structure material in a butted state using the building base material fixing bracket, as a building base material fixing bracket. As described above, the substantially flat plate-like base part, the standing part rising substantially vertically from the base part, and extending at a predetermined angle from the upper end of the standing part toward at least one side can be bent. In addition, there is used one having a fixing portion in which a sharp locking claw is bent downward from its tip. This shape and configuration are as described above.

  By using the building base material fixing bracket of the present invention, the building base material can be firmly fixed to the base structure material, and the movement between adjacent building base materials can be restricted, so that the nail The movement of the building base material can be sealed together with the fixing by the fixing tool such as the above, and it is possible to prevent the mortar surface from being cracked due to this.

  In addition, when fixing the building base material to the base structure material, the locking claw at the tip of the fixing portion of the fixing bracket can be temporarily fixed by driving into the surface of the building base material. The fixing work of the building base material becomes easy and the workability is improved.

  An example of the building base material fixing structure thus obtained is shown in FIG. 8, and the exterior wall surface structure obtained by performing caulking material filling and mortar coating on this building base material fixing structure is shown in FIG. It is shown. In addition, although the fixing bracket 10a of FIG. 2 is used in the building base material fixing structure of FIG. 8, even if the fixing bracket 10 of FIG. 1 or the fixing bracket 10b of FIG. A structure is obtained.

  In FIG. 8 and FIG. 9, reference numeral 1 is a building base material, and mortar M (generally referring to plastering coating materials such as plaster and spray coating) can be directly applied thereon. The specific configuration is not limited, but as an example, on the surface of a woody base material such as plywood or fiberboard, or an inorganic base material 2 such as asbestos slate or calcium oxalate, synthetic resin emulsion, asphalt, asphalt emulsion, After forming a waterproof layer 3 by applying rubber latex or the like, an inorganic binder such as cement or lime, and an aggregate such as sand, cinnabar, charcoal, hillstone, pearlite, synthetic resin particles, or synthetic resin foam particles Examples of the structure in which the uneven layer 4 is formed by applying a mixture of a synthetic resin emulsion, a rubber latex, and an asphalt emulsion. The waterproofing layer 3 and / or the uneven layer 4 may be formed on the entire surface area including the chamfered portion by chamfering the surface side of the butted end portion of the building base materials 1 and 1.

  The building base materials 1, 1 are fitted into a space surrounded by the base portion 11, the standing portion 12, and the fixing portion 13 of each of the fixed metal fittings 10, and the front end of the fixing portion 13 is engaged with the surface. In the state where the pawl 14 is engaged and fixed (temporarily fixed), it is placed in a butted state on the base structure material 5 and further driven through the fixing bracket 10 from the surface of the building base material 1, 1. The base structure material 5 is fixed by a fixing tool 6 such as a nail or a screw. Since the fixture 6 penetrates the building base materials 1 and 1 from the base portion 11 of the fixture 10 and is driven into the base structure material 5, the fixture 6 is fixed to the building base material and at the same time the building base material 1. , 1 are fixed to the base structure material 5. As shown in FIG. 9, an air receiving member 5 b may be interposed between the pillar 5 a (or the stud, body edge, etc.) and the building base materials 1, 1 in order to secure a ventilation layer. The base structure material 5 is composed of the pillar 5a and the vent receiving material 5b.

  The caulking material 7 is filled in the butted end portions (joint portions) of the building base materials 1 and 1 thus fixed. The caulking material 7 is filled in an area sufficient to completely hide the fixing portion 13 of the fixing bracket 10 and the head of the fixing tool 6, and the surface thereof is as flush and smooth as possible with the surfaces of the building base materials 1, 1. Consider to be.

  The joint covering material 8 is arranged so as to completely cover the joint portion of the building base material 1 and 1 including the surface of the caulking material 7, and fixed on the building base material 1 and 1 with fixing tools 9 such as nails and staples. Is done.

  As the joint covering material 8, for example, a net-like base material sheet can be used. The mortar is highly alkaline, and when the sheet-like base material is affected by alkali and becomes brittle, the portion where the joint covering material 8 was present becomes voids, the adhesiveness with the mortar is reduced, and peeling or cracking occurs in the mortar. Therefore, in order to prevent such a problem, the net-like base material sheet is preferably formed of a material having alkali resistance. Moreover, it is preferable to have the strength and flexibility necessary to prevent the occurrence of cracks following the behavior of the mortar accompanying the expansion and contraction of the building base material. Suitable materials for the net-like base sheet satisfying these required performances are polyamide fibers, acrylic fibers, polyethylene fibers, polypropylene fibers, polyvinyl alcohol fibers, cotton fibers, alkali-resistant glass fibers, and carbon fibers. Or, it is an inorganic fiber, and a net obtained by weaving single or plural kinds of fibers arbitrarily selected from these can be used as a net-like base material sheet, particularly an acrylic fiber net / alkali-resistant glass fiber net A cotton fiber net or a polyvinyl alcohol fiber net is preferably used.

  By using a net-like base material sheet as the joint covering material 8, the anchoring effect on the opening (mesh) improves the adhesiveness of the mortar, and is excellent in the effect of suppressing peeling and cracking. The adhesiveness of the mortar varies depending on the particle size of the fine aggregate (sand) or light aggregate contained in the mortar, but the opening width dimension of each mesh of the net is 1.0 to 7.0 mm, particularly 3.0 to 5 By setting the thickness to 0.0 mm, it is possible to give good mortar adhesion in accordance with the particle size range of the aggregate generally used.

  Thus, the building foundation fixing structure using the fixing bracket 10 (10a, 10b) is completed, and the mortar M is directly applied thereon to finish the exterior.

  The work procedure for constructing a building base material using the fixing brackets 10, 10a, 10b will be described in more detail. First, one end of one building base material is constructed so as to be along one end of the wall surface. Then, construction is sequentially performed so that one end of another building base material is abutted against the other end. When fixing the building base materials in a butted state, the fixing brackets 10, 10a, 10b for connection as described above are used, but one building base material is fixed to one side at the end of the wall surface. Therefore, the wall end fixing bracket 10c as shown in FIG. 10 is used. The fixture 10c includes a substantially flat base portion 11c, a standing portion 12c that rises substantially vertically from one side edge in the width direction of the base portion 11c and continues over the entire length in the longitudinal direction, and an upper end of the standing portion 12c. And a fixing portion 13c extending in a slanting manner at a predetermined angle in the direction in which the base portion 11c exists, and a sharp locking claw 14c is bent downward at the tip of each fixing portion 13c. ing. A plurality of fixture holes 15c are formed at predetermined intervals along the other side edge in the width direction of the base portion 11c. In this embodiment, the fixing portion 13c is provided intermittently at a predetermined interval. As described above with reference to FIG. 4, the fixing bracket 10 c corresponds to one member when the connecting fixing brackets 10, 10 a, 10 b are formed by joining two identical members back to back. .

  For example, when constructing the building base material in order from the left side to the right side of the wall surface, such a fixing member 10c for the wall end portion is placed along the standing portion 12c at the left end portion of the wall surface to be stretched. At this position, a fixture such as a nail or staple is struck from the fixture hole 15c and fixed to the base structure material 5 in advance.

  Accordingly, the space surrounded by the base portion 11c, the standing portion 12c, and the fixing portion 13c of the fixing bracket 10c faces the direction (right side) in which the building base material should be applied. After inserting and positioning one end of the building base material, the fixing portion 13c is bent so that the surface of the fixing portion 13c is flush with the surface of the building base material, and the locking claw 14c at the tip of the fixing portion 13c is bent. Is hammered into the surface of the building base material with a hammer or the like.

  Next, when one of the connecting fixtures 10, 10a, 10b is used and the fixtures 10, 10a are used, the base portions 11, 11a, the standing portions 12, 12a, and the fixing portions 13, 13a When the fixing bracket 10b is used in one of the enclosed spaces, the other end of the fixed building base material is fitted so as to abut against the standing portion 12b on the side where the base portion 11b does not exist. After inserting and positioning, the fixing portion c is bent so that the surfaces of the fixing portions 13, 13a, 13b are flush with the surface of the building base material, and the locking claws 14, 14a, 14b at the tips thereof Is temporarily fixed to the surface of the building base material with a hammer or the like.

  At this time, since the other side of the base portions 11 and 11a of the fixing brackets 10 and 10a or the base portion 11b of the fixing bracket 10b is exposed, the fixture holes 15 and 15a provided on the exposed surface are provided. , 15b, and a fixing tool such as a nail or a screw is driven into the base structure material 5.

  Then, the building base material to be constructed next is the base parts 11, 11a, 11b, the standing parts 12, 12a, 12b and the fixing parts 13, 13a, 13b from the other side of the fixed metal fitting. After being inserted into the enclosed space and positioned, the fixed portion is bent so that the surfaces of the fixed portions 13, 13a, 13b are flush with the surface of the building base material, and the locking claw 14 at the tip of the fixed portion is bent. , 14a, 14b are driven into the surface of the building base material with a hammer or the like.

  Thereafter, the above operation is repeated, and after fixing the building base material on the entire wall surface, the fixing device 6 such as a nail and a screw is driven into the four peripheral edges and other predetermined positions of each building base material to perform the main fixing. Do. In this way, the building base material fixing structure described above (FIG. 8) is formed.

  Thereafter, as described above, the caulking material 7 is applied and filled in the portion (joint portion) where the building base materials are abutted to prevent rainwater from entering, and further, the coating filling portion of the caulking material 7 is straddled. Then, after the joint covering material 8 is constructed, the mortar M is applied to the entire surface, and the exterior wall surface structure shown in FIG. 9 is obtained. After the application of the mortar M, finish coating may be performed as necessary.

  According to such a construction procedure, the construction base material is constructed in a state in which the locking claws 14, 14a, 14b, and 14c of the fixing bracket are driven and temporarily fixed to the surface of one end of the construction base material. Therefore, it is not necessary to drive a nail or the like while holding the building base material so that it does not fall down, and the workability is improved.

  The construction procedure described above is not limited and can be variously changed. For example, instead of using the end fixing bracket 10c as shown in FIG. 10 at the end of the wall surface where the building base material starts to be tensioned, the base for building is typically performed by nailing or the like. The tension start end of the material may be fixed to the base structure material 5.

  In the above description, the final fixing of the building base material is performed at the final stage, but after temporarily fixing one end of the building base material with the locking claws 14, 14a, 14b, four times each time. The fixing of the base material for construction may be performed by driving a fixing tool 6 such as a nail or a screw into the peripheral edge or other predetermined location. In particular, when the fixing bracket 10b shown in FIG. 3 is used, even if the fixing tool 6 is driven into the other end of the building base material on which one end is temporarily fixed, the base portion 11b is fixed. Since there is no need to insert it into the back side of the building base material, it is possible to drive the locking claw 14b by placing the fixing bracket 10b so that the butt end is abutted against the standing portion 12b. There will be no hindrance to construction. Moreover, even if it is a case where the fixing metal fittings 10 and 10a which have the base parts 11 and 11a on both sides are used, the fixing tool 6 is driven into the other wooden mouth part of the building | foundation base material in which one wooden edge part is already temporarily fixed. At this time, if the main fixing is performed so as to leave room for the base portion 11b to enter the back side, the same construction as described above is possible.

  The main fixing of the building base material is performed by driving the fixing tool 6 into the four peripheral edges or other predetermined locations. However, even if the fixing tool is driven through the base and / or the fixing part, the fixing metal is not fixed. You may drive in a position that does not exist. In the former case, it is necessary to select the material and thickness of the fixing bracket so that the base portion and / or the fixing portion of the fixing bracket can be penetrated by a normal force for driving the fixing tool.

  In the above, although the construction point using the fixing bracket in the vertical direction has been described, it goes without saying that the fixing bracket may be used in the horizontal direction or in both the vertical and horizontal directions.

  Further, FIG. 9 shows an example of construction by a ventilation method in which an air receiving material 5b is attached on the pillar 5a and an architectural base material is pasted, but the air receiving material 5b is attached on the pillar 5a.
