Description

The present invention relates to an interior / exterior material fixture for fixing an interior / exterior material to a formwork panel for a concrete formwork, and a formwork panel .

 In recent years, in the formwork panel used for concrete placement, a steelwork formwork panel has become widespread instead of a wood plywood formwork panel. The formwork panel made of steel plate is usually buried in the ground without being dismantled and removed after placing and hardening concrete, as the formwork for building the foundation of the building. There is an advantage in that it is possible to reduce the labor cost, construction period and transportation cost by removing materials or transporting from the construction site.

 In this way, the steel plate formwork panel is buried as it is when building the foundation of the building, while it is removed from the wall surface when building the wall surface of the ground floor of the building. It is left exposed without any problems. Therefore, it is necessary to install an interior / exterior material that covers the exposed formwork panel, and the following techniques are provided.

  For example, there is provided a concrete wall structure that engages and fixes a form panel made of a square corrugated metal plate and a foamed synthetic resin molded panel, which are disposed in a buried state when a concrete wall is formed, using an engagement piece. (Patent Document 1, paragraphs “0023” and “FIG. 5”). The engaging piece includes a connecting portion having one end connected to the bottom surface of a concave groove formed on the surface of the mold panel, and a thick portion at the other end is in contact with the foamed synthetic resin molded panel, It can be fixed by driving a screw or the like through the synthetic resin molded panel.

  Further, the insertion tool is fitted into a separator hole formed in the mold panel, and is formed in a long cylindrical shape having a screw insertion hole that opens or penetrates in one side, and is perpendicular to the insertion direction of the screw insertion hole. An insertion tool is provided in which a pair of grooves cut out in a direction are formed in parallel so as to face each other on the outer peripheral surface of the long cylindrical shape (Patent Document 2), and a narrow width extending downward from a large opening of the formwork panel After inserting the insertion tool into the separator hole made up of the small opening, the groove formed in the insertion tool is fitted and fixed to the edge of the small opening so that the screw is inserted into the screw insertion hole of the insertion tool. The inner and outer materials can be attached by screwing.

 Hereinafter, the present invention will be specifically described with reference to the drawings. First, a first embodiment of the fixture according to the present invention will be described in detail with reference to FIGS. FIG. 1 is a perspective view showing the fixture 1, and the fixture 1 is a cylindrical main body portion 2 having a rectangular shape in cross section and a part of the peripheral surface of the main body portion 2. It is comprised from the latching piece 3 as a connection part which protruded from the side view and was formed in the L-shape key shape.

 The fixture 1 is attached to a rib portion 4a having a substantially U-shaped cross section formed by bending a plurality of formwork panels 4 which are metal thin plates for concrete formwork used when placing concrete. It is. Therefore, the main body 2 is a metal having a size that can be fitted into the rib portion 4a formed on the formwork panel 4 as shown in a perspective view showing a state in which the fixture 1 of FIG. The locking piece 3 is formed in an L-shaped key shape that can be locked in a separator hole 4b that penetrates the bottom surface of the rib portion 4a. Usually, when assembling a concrete formwork, the separator hole 4b is formed on the bottom surface of the rib portion 4a in order to insert a separator (not shown) that bridges and fixes a pair of opposing formwork panels 4. A plurality of them are formed at distance intervals, and the locking piece 3 is locked in any separator hole 4b, and the fixture 1 is mounted on the formwork panel 4. Note that the fixture 1 is not limited to metal, and may be composed of a main body 2 and a locking piece 3 made of synthetic resin or wood, and may be made of metal, synthetic resin or The main body 2 and the locking piece 3 formed of a combination of wood may be used.

 FIG. 3 is a side sectional view showing a state in which the fixture 1 is mounted on the formwork panel 4, and FIG. 4 is a sectional plan view thereof. As shown in FIG. 3, the fixture 1 has a separator hole in which an L-shaped locking piece 3 formed on the peripheral surface of the main body portion 2 is formed on the bottom surface of the rib portion 4 a of the mold panel 4. Locked to 4b and mounted on the formwork panel 4 along the rib portion 4a.

 Further, as shown in FIG. 4, of the peripheral surface of the main body 2, the surface on which the locking piece 3 is formed, that is, the surface facing the rib portion 4 a when attached to the formwork panel 4 is a rib. It is formed to be slightly wider than the bottom surface of the portion 4a. When the fixture 1 is mounted on the formwork panel 4, the main body portion 2 and the bottom surface of the rib portion 4b are not in contact with each other, and a slight gap is formed. Furthermore, the inclination angle from the surface of the main body 2 where the locking piece 3 is provided to both side surfaces is slightly steeper than the inclination angle from the bottom surface of the rib portion 4a of the mold panel 4 to both side surfaces. Since the inclination angle of the rib portion 4a and the side surface of the main body portion 2 with respect to the bottom surface of the rib portion 4a is different, a slight gap is also formed between both side surfaces of the main body portion 2 and the side surface of the rib portion 4a. Further, since the main body 2 is formed of a rectangular tubular body that is larger than the depth direction of the rib 4a, the fixture 1 is formed from the rib 4a by a length of the protruding width α. 4 is attached. That is, both side surfaces of the rib portion 4a of the formwork panel 4 are formed with inclined surfaces that are gentler than the inclination angle of both side surfaces of the main body portion 2 of the rib portion 4a, and are shallower than the rectangular tube shape of the main body portion 2. It is formed in a groove shape. Further, the bottom surface of the rib portion 4a of the formwork panel 4 is formed to be narrower than the opposing surface of the bottom surface of the rib portion 4a of the fixture 1, so that when the fixture 1 is mounted on the rib portion 4a, the main body of the fixture 1 Since the portion 2 comes into contact with the inclined surfaces on both sides of the rib portion 4a and stops, a gap is formed between the bottom surface of the rib portion 4a and the fixture 1, thereby generating the protruding width α.

 Here, the fixture 1 has a length of 80 mm in the longitudinal direction of the main body 2, a width of the inclined surface of 13 mm, a width of the surface facing the rib portion 4 a when attached to the formwork panel 4, and an outer side. The width of the surface to which the inner / outer packaging material 5 is attached is formed with a dimension of 22 mm, and the locking piece 3 of the fixture 1 has an L-shaped key shape in side view and protrudes from the surface of the main body 2 with a width of 1 mm. From there, it is formed with a dimension of 15 mm downward. By forming the rib portion 4 a of the mold panel 4 so as to correspond to the dimensions of the fixture 1, the fixture 1 can be appropriately attached to the mold panel 4. The size of the fixture 1 is not limited to the size of the fixture 1 of the embodiment, and may be formed in the fixture 1 having a size according to the attachment of the inner and outer materials 5. What is necessary is just to form the rib part 4a of the formwork panel 4 so that it can mount | wear appropriately according to the dimension of 1.

 As described above, the peripheral surface of the fixture 1 on which the locking piece 3 is formed is opposed to the bottom surface side of the rib portion 4a, and the main body portion 2 of the fixture 1 is fitted into the rib portion 4a. The fixture 1 is mounted on the formwork panel 4 by locking the locking piece 3 in the separator hole 4b. The fixture 1 is to be mounted on the formwork panel 4 after assembling the formwork panel 4 to form a concrete formwork. Then, concrete is placed in the concrete formwork, and after the concrete is hardened, the inner and outer materials 5 are attached to the fixture 1.

 Next, how to attach the inner / outer packaging material 5 to the fixture 1 attached to the formwork panel 4 will be described below with reference to FIGS.

 FIG. 5 is a perspective view showing a state in which the interior / exterior material 5 is installed on the formwork panel 4. As described above, the inner and outer materials 5 are brought into contact with the exposed surface of the main body portion 2 of the fixture 1 attached to the separator hole 4b arbitrarily selected among the plurality of separator holes 4b on the bottom surface of the rib portion 4a, Screws 6 are passed through the main body 2 and the interior / exterior material 5 and screwed together, and the interior / exterior material 5 is fixed to the fixture 1 attached to the formwork panel 4. The attachment location and the number of attachments to the formwork panel 4 of the fixture 1 may be arbitrarily determined according to the size of the inner and outer materials 5. Thus, unlike the case where the screw 6 is driven into a screw hole or the like, the screw 6 can be driven anywhere within the exposed surface of the main body 2 of the fixture 1. Even from the outside of 5, the inner and outer materials 5 can be installed on the formwork panel 4 by easily screwing the screws 6. The screw 6 may use a drill screw or the like suitable for penetrating the peripheral surface of the fixture 1.

 FIG. 6 is a cross-sectional side view showing a state in which the interior / exterior material 5 is installed on the formwork panel 4, and FIG. 7 is a cross-sectional view in plan view. As described above with reference to FIG. 4, the main body 2 of the fixture 1 protrudes outward from the formwork panel 4 by the protrusion width α, so when the inner and outer materials 5 are installed on the formwork panel 4, A space is formed in the gap between the formwork panel 4 and the interior / exterior material 5. The space can be used as a ventilation layer between a heat insulating material (not shown) installed in the building partition and the interior / exterior material 5. Can also be realized easily. In addition, even if the cylindrical shape of the fixture 1 is formed to such an extent that the inner and outer packaging materials 5 are in contact with the formwork panel 4 without providing the protrusion width α, the effect of the present invention can be achieved. Needless to say.

 Further, surplus water or residual rainwater of the concrete is discharged through the separator hole 4b when the concrete is placed from the surface facing the bottom surface of the rib portion 4a of the main body portion 2 described in FIG. 4 and the gap between the rib portions 4a. The If the surplus water or the like remains in the concrete without being discharged, the strength after hardening of the concrete is lowered, so that it is necessary to discharge the surplus water and the like sufficiently. Further, since the gap is filled with concrete at the same time as the discharge of excess water or the like, it is possible to contribute to fixing the fixture 1 to the formwork panel 4.

 In addition, even if it makes it contact without providing a gap | interval between the surface which opposes the rib part 4a of the said main-body part 2, and the rib part 4a bottom face, the seismic isolation and the earthquake-proof effect based on this invention can be acquired. Also in this case, a notch or the like for discharging surplus water or the like of the placed concrete may be provided separately to discharge the surplus water or the like.

 Further, since the gap is formed between the both side surfaces of the main body 2 and the side surfaces of the rib portion 4a, the main body 2 which is a square cylindrical body when the vibration such as an earthquake occurs is shown in FIGS. As shown in FIG. 8B, the interior / exterior material is bent in the left-right direction within the gap to absorb shaking such as an earthquake, or as shown in FIGS. As the surface 5 moves back and forth, the surface of the main body 2 facing the interior / exterior material 5 bends in the front / rear direction due to the weight of the interior / exterior material 5 to absorb vibrations such as earthquakes. It can be obtained, and it is possible to prevent the tiles and decorations attached to the interior / exterior material from being peeled and dropped, and the internal / exterior material from being broken or cracked. At this time, the opposing surface on the bottom surface side of the rib portion 4a of the main body 2 is fixed with concrete as described above, and therefore does not move due to shaking such as an earthquake. In addition, by forming the main body portion 2 in a shape corresponding to the groove shape of the rib portion 2, the inner and outer material 5 of the main body portion 2 can be formed even if no gap is formed between the both side surfaces of the main body portion 2 and the rib portion 4 a. The deflection in the front-rear direction of the surface opposed to can be realized, and can sufficiently absorb shaking such as an earthquake.

 As described above, if the fixture 1 is used, the screw 6 can be driven through the exposed surface of the main body 2 instead of the screw hole, so long as the exposed surface is within the range. However, since the screw 6 can be driven in, the interior / exterior material 1 can be easily installed on the formwork panel 4, and the excess water or residual rainwater is sufficiently discharged. A fall can be prevented, and further, by providing a gap between the fixture 1 and the rib portion 4a of the formwork panel 4, it is possible to obtain the seismic isolation and seismic effect for the inner and outer materials 5.

 FIG. 9 is a perspective view showing the fixture 1 of the second embodiment. The fixture 1 is provided with a connecting piece 3 'as a connecting portion having screw holes 3'a at the upper and lower ends of the surface facing the bottom surface of the rib portion 4a of the main body portion 2 of the square cylindrical body. FIG. 10 is a perspective view showing a state in which the fixture 1 of the embodiment is mounted on the formwork panel 4. A screw hole provided in the connection piece 3 ′ is brought into contact with the bottom surface of the rib part 4 a of the formwork panel 4 with the surface provided with the connection piece 3 ′ on the upper and lower ends of the main body 2 of the fixture 1. The fixture 1 is attached to the formwork panel 4 by inserting the screw 7 into 3′a and screwing it onto the bottom surface of the rib portion 4a. Since the fixture 1 of this embodiment does not need to lock the locking piece 3 to the separator hole 4b when it is installed on the formwork panel 4 as in the above embodiment, the separator hole can be used as long as it is the bottom surface of the rib portion 4a. Even if 4b is not formed, the fixture 1 can be mounted at an arbitrary location. In addition, since a separator (not shown) is inserted into the existing separator hole 4b, it becomes difficult to discharge excess water or the like when the separator hole 4b is blocked. Water or the like may be discharged. In the present embodiment, the connecting piece 3 ′ is formed to protrude by 15 mm with the same width from the surface facing the rib portion 2a of the main body 2, and the screw hole 3 ′ is formed with a diameter of 3 mm. The dimensions are not limited and may be appropriately formed according to the dimensions of the fixture 1.

 FIG. 11 is a perspective view showing the fixture 1 of the third embodiment. The fixture 1 includes a main body 2 formed by connecting a triangular cylindrical body to one surface of a flat plate, and a locking piece 3 provided on the other surface of the flat plate. The fixture 3 is attached to the formwork panel 4 by engaging the locking piece 3 in the separator hole 4b with the flat plate facing the bottom surface of the rib 4a. Note that the connecting piece 3 ′ may be provided on the upper and lower ends of the flat plate instead of the locking piece 3, and the fixture 1 may be fixed to the bottom surface of the rib portion 4 a.

 Thus, the fixture 1 is not limited to the main body 2 and the locking piece 3 of the rectangular tubular body, and may be a cylindrical shape or a polygonal cylindrical shape, and in the second embodiment. As shown, it may be fixed to the bottom surface of the rib portion 4a by the connecting piece 3 '.

 Further, in the fixture 1 provided with the above-mentioned locking pieces 3, as shown in FIG. 12, two locking pieces 3 are provided vertically along the interval of the separator holes 4b formed in the mold panel 4. It's okay. By locking the upper and lower locking pieces 3 in the separator holes 4b, the fixture 1 can be attached to the form panel 4 more firmly than in the above embodiment. The interval width between the two locking pieces 3 provided above and below is about 5 mm, but the interval width between the two locking pieces 3 is set according to the relationship with the opening interval width of the separator hole 4b.

 Here, the two locking pieces 3 are provided above and below the main body 2, but a separator hole in which three or more locking pieces 3 are formed in the mold panel 4 according to the size of the main body 2. You may provide corresponding to 4b. Further, in the first embodiment, the locking piece 3 as the connecting portion is provided below the center in the longitudinal direction of the main body portion 2 (see FIG. 1). May be.

 As another embodiment, a fixture 1 in which the locking piece 3 is formed in a trifurcated manner in the vertical direction will be described with reference to FIGS. 13 (a) and 13 (b). FIG. 13A is an external perspective view showing the fixture 1, and FIG. 13B is a cross-sectional view thereof. As shown in FIG. 13A, the locking piece 3 of this embodiment is divided into three forks with a slit in the longitudinal direction of the locking piece 3, a central locking piece 3a at the center, and a left engagement at the left side. A stop piece 3b and a right locking piece 3c are formed. The center locking piece 3a, the left locking piece 3b and the right locking piece 3c can be bent, respectively. For example, as shown in FIG. 13 (b), the left locking piece 3b and the right locking piece 3c On the other hand, the center locking piece 3a is used by bending the center locking piece 3a vertically or in the direction opposite to the left locking piece 3b and the right locking piece 3c as indicated by a broken line in the figure.

 In this way, by bending the central locking piece 3a, the central locking piece 3a is deeply buried in the concrete cast over the left locking piece 3b and the right locking piece 3c. Thereby, it is possible to prevent the locking piece 3 from being easily pulled out from the hardened concrete, and as a result, the fixture 1 and the interior / exterior material 5 attached to the fixture 1 easily fall off. It is possible to improve safety for construction workers or users of buildings.

  Moreover, the fixture 1 of another Example is demonstrated using Fig.14 (a) and (b). FIG. 14A is an external perspective view showing the fixture 1, and FIG. 14B is a developed view thereof. The mounting tool 1 is formed so that the surface of the cylindrical main body 2 on which the locking piece 3 is provided is divided into two along with the locking piece 3 in the longitudinal direction so that the mounting tool 1 can be unfolded. When the fixture 1 is used, the split piece 3 is locked in the separator hole 2b so that the cylindrical shape of the fixture 1 is maintained. It will not be.

  By forming the fixture 1 in such a manner that the fixture 1 can be unfolded, it is not necessary to weld the metal plate into a cylindrical shape at the time of manufacturing the fixture 1, and to maintain the cylindrical shape. Since it is sufficient to fold it into a cylinder, manufacturing is easy, and manufacturing cost can be reduced.

  Moreover, the fixture 1 of another Example is demonstrated using Fig.15 (a) and (b). FIG. 15A is an external perspective view showing the fixture 1, and FIG. 15B is a developed view thereof. The fixture 1 is provided with a locking piece 3 on a cylindrical main body 2, and connection pieces 3 ′ on the upper and lower ends of the surface on which the locking piece 3 is provided. When the surface of the main body 2 on which the locking piece 3 of the portion 2 is provided is divided into two along with the locking piece 3 in the longitudinal direction, the connection piece 3 ′ is provided only on either the left or right side of the divided surface. It is extended. Further, a screw hole 3'a is formed in the connection piece 3 '. When using the fixture 1, in addition to locking the locking piece 3 to the separator hole 4b, the screw hole 3'a of the connection piece 3 'is screwed to the bottom surface of the rib portion 4a.
