The ceiling panel 14 is fixed by fastening the ceiling panel 14 and the lightweight panel 1 arranged below the ceiling panel 14 with U-shaped fasteners.

The lightweight panel 1 uses polystyrene foam (EPS (expandable polystyrene beads)), which is easily molded by foaming beads, and has a thickness of 200 mm, a bulk specific gravity of 166 kg/m ³ , and an expansion ratio of 6 times. did. Since the lightweight panel 1 can be easily cut with a cutter knife or the like, the size of the lightweight panel 1 can be easily adjusted. Therefore, the size can be set according to the size of the opening 34 formed in the gate structure member 3 .

As the support member 21 used between the panels, an iron L-shaped angle with a side length of 50 mm was used. The support member 21 is placed on the installation surface G on which the lightweight panel 1 is installed so that the longitudinal direction (longitudinal direction) is perpendicular to the installation surface G, and as shown in FIGS. The angle is fixed so that an imaginary line connecting both ends of the cross section in the lateral direction (horizontal direction) of the angle is parallel to the connection direction of the lightweight panel 1 .

As the support member 21a used in the panel, an iron L-shaped angle with a side length of 50 mm was used. As shown in FIGS. 2 and 3, the support member 21a is mounted on the installation surface G on which the lightweight panel 1 is installed so that the sides of the L-shaped angle are parallel to the connection direction of the lightweight panel 1, and are mounted on the installation surface. Fix so that the longitudinal direction is perpendicular to G.

The bonding cement composition used was a cement-based non-shrink grout material blended with cement and aggregate. Cement-based non-shrinkage grout material has high slurry fluidity, and the slurry may leak from the gaps between the lightweight panels 1. Therefore, by blending cement and aggregates, the fluidity of the slurry was reduced. It is. In addition, the bonding cement composition maintains the non-shrinkage property of the cement-based non-shrink grout material, and hardly shrinks when the inter-panel through-holes 18 are filled with slurry of the bonding cement composition and hardened. Therefore, there is no gap due to shrinkage between the jointing cement molding formed from the slurry of the jointing cement composition and the inter-panel through-hole 18, and rainwater does not enter the wall material made of the lightweight panel 1. can be prevented. Any commercially available cement-based non-shrink grout material can be used as the cement-based non-shrink grout material.

Cement uses Portland cement (ordinary Portland cement) specified in JIS R 5210: 2019, and commercially available silica sand (silica sand No. 6 (average particle size (d50): about 0.37 mm)) is used as aggregate. Using.

The blending ratio of the cement-based non-shrinkage grout material is 100, ordinary Portland cement is 50, and silica sand is 150. The slurry of the cement composition has a 100 mm PVC flow test value (JASS 15 M-103) of 125. Adjust the amount of water added so that it becomes ~250 mm. More preferably, the amount of water added is adjusted so that the 100 mm PVC flow test value of the slurry of the joint cement composition is 150-200.

The test method for the 100 mm PVC flow test value (mm) (JASS 15 M-103 "Quality standard for self-leveling materials") is as follows. A vinyl chloride pipe (inner volume: 196 mL) with an inner diameter of 50 mm and a height of 100 mm is placed on a 5 mm thick polished plate glass. , the diameters in two perpendicular directions were measured, and the average was taken as the flow test value (mm).

The cement composition is a powdery material in which cement, aggregate and other additives are uniformly mixed. When the cement composition is kneaded with water, it becomes a slurry (paint) that has fluidity and can be coated or filled. By hardening the cement in the slurry through a hydration reaction, the slurry of the cement composition becomes a cement molding as a hardened body.

The ceiling portion behind the garage shutter gate 100 is covered with a roof member (not shown). A corrugated polycarbonate plate was used for the roof member. The roof member extends rearward from the lower side (inner side) of the shutter accommodating portion 41 .

The construction method of the garage of the embodiment includes a setting step of placing the installation surface G while installing the gate member 3 and the support members 21 and 21a, and a joining step of joining the shutter housing portion 41 to the gate member 3. , an installation step of installing the lightweight panels 1 along the installed support members 21 and 21a, a seam stretching step of performing seam stretching reinforcement between the installed lightweight panels 1, and an inter-panel through hole 18 between the lightweight panels 1. A filling step of filling the slurry of the bonding cement composition into the space, a step of installing the ceiling panel 14, and a step of installing the roof member were carried out in this order.

In the casting process, a concrete base portion F that serves as the foundation of the structure is provided at the opening 34, the gate structure member 3 is erected in the hole provided in the base portion F, and the lightweight panel 1 is installed. The support members 21 and 21a were erected in holes provided in the base portion F in accordance with the positions where the support members 21 and 21a were formed. In the gate structure member 3, a support frame 31, a beam frame 32, and an auxiliary frame 33 are joined in advance by welding. The supporting member 21 arranged between the lightweight panels 1 uses an L-shaped angle with a side length of 50 mm, and is arranged so that the virtual line of the L-shaped angle is parallel to the connecting direction of the installed lightweight panels 1. . The support member 21a arranged in the lightweight panel 1 uses an L-shaped angle with a side length of 50 mm, and is arranged so that the side of the L-shaped angle is parallel or perpendicular to the surface of the lightweight panel 1 to be installed. The support members 21 and 21a are arranged so that their longitudinal directions are perpendicular to the place where the garage is installed. After that, a concrete slurry was placed in the range to be the installation surface G of the garage. The installation surface G is formed by hardening the concrete slurry.

In the joining step, after the concrete slurry has hardened, first, the shutter accommodating portion 41 is joined to the rear surfaces of the upper and lower beam frames 32 of the gate structure member 3 with screws.

As a first step of the installation process of the lightweight panel 1, as shown in FIG. Install. The role object panel 10 is arranged from above so that the support member 21a is inserted into the vertical through hole 10b of the role object panel 10.例文帳に追加When the accessory panel 10 is arranged, the support frame 31 contacts the notch 10 a of the accessory panel 10 . The inner panel 11 is arranged from the front side so that the front side surface matches the surface of the accessory panel 10 and is aligned with the support member 21.例文帳に追加The rear panel 12 is arranged from the rear side of the support frame 31 so as to close the support frame 31 in the circumferential direction and in accordance with the support member 21 .

The second step of the installation process is to place the gate panel 13 . As shown in FIG. 7, the gate panel 13 is arranged in front of the upper and lower beam frames 32 so as to be sandwiched between the left and right accessory panels 10 (FIG. 2). At this time, the horizontal through-holes 10c of the left and right accessory panels 10 and the horizontal through-holes 13c of the gate panel 13 are arranged so as to communicate with each other in the left-right direction. Next, the hanging member 22 is inserted through the communicating horizontal through-hole 10c and the horizontal through-hole 13c. It is screwed to the support member 21 that is in place. The gate panel 13 is fixed by screwing.

In the third step of the installation process, as shown in FIGS. 2, 3 and 7, the side wall panels 15, which will be the side walls of the garage, are aligned with the support members 21. As shown in FIG. Since the arranged lightweight panel 1 is provided with cutout recesses 17 along the vertical direction of the mating surface 16, when the lightweight panel 1 is installed, from each of the cutout recesses 17 of the mating surface 16 of the lightweight panel 1 An inter-panel through hole 18 is formed. Since the two lightweight panels 1 are installed with the support member 21 interposed therebetween, the support member 21 is inserted through the inter-panel through hole 18 formed from the notch recess 17 .

In the jointing process, the gaps in the inter-panel through holes 18 are filled. The abutment surface 16 between the lightweight panels 1 (including the abutment surface between the accessory panel 10 and the inner panel 11 and the abutment surface between the accessory panel 10 and the rear panel 12), which is the joint of the inter-panel through hole 18, includes: As shown in FIG. 6, a silicone-based caulking material 51 was applied to bond the lightweight panels 1 together. Moreover, the caulking material 51 was also applied between the lightweight panel 1 and the installation surface G, and the lightweight panel 1 and the installation surface G were adhered. As a result, the gap between the lightweight panels 1 is filled with the caulking material 51, and the inter-panel through-hole 18 is filled vertically. As shown in FIG. 6, in order to prevent the slurry of the joint cement composition to be filled in the next filling step from flowing out from the weakly adhered portions of the caulking material 51, a reinforcement such as cloth adhesive tape is placed between the lightweight panels 1. A tape 52 was applied. Next, a plate-like support material 53 for preventing the upper end side of the inter-panel through-hole 18 from opening is brought into contact with both widths of the upper end portion straddling between the lightweight panels 1, and clamped (not shown). Fixed.

In the filling step, the inter-panel through-hole 18 and the vertical through-hole 10b of the accessory panel were filled with slurry of the bonding cement composition. The amount of water added to the slurry of the joint cement composition was adjusted so that the 100 mm PVC flow test value was 125 to 250 mm. A slurry of a cement composition having a 100 mm PVC flow test value of 125 to 250 mm has moderate fluidity, so that it can be easily filled into the inter-panel through-hole 18 . Therefore, the garage of the embodiment can be excellent in workability during construction. The slurry of cementitious composition hardens to form a cementitious molding 23 to form the wall material of the lightweight panels 1 of the garage. In the embodiment, the slurry of the cement composition used has the following composition.

Grout material 100 parts by mass Ordinary Portland cement (JIS R 5210:2019) 50 parts by mass Silica sand No. 6 (average particle size (d50): about 0.37 mm) 150 parts by mass Mixing water 39.1 parts by mass Eurox Super (cement-based non-shrink grout material manufactured by Taiheiyo Material Co., Ltd.) was used. The 100 mm PVC flow test value (JASS 15 M-103) of the slurry of the joint cement composition was 172 mm.

After the filling process, it is confirmed that the slurry of the cement composition has hardened and the cement molding 23 has been molded, and the auxiliary materials such as the reinforcing tape 52 and the support material 53 are removed.

In the step of installing the ceiling panel 14, as shown in FIGS. 1 and 7, the gate structure member 3, the shutter housing portion 41 (FIG. 6), and the accessory panel 10, the gate panel 13, and the rear panel covering them from the horizontal direction. A ceiling panel 14 is arranged so as to cover 12 from above. The ceiling panel 14 is fixed by fastening the ceiling panel 14, the accessory panel 10, the gate panel 13 and the rear panel 12 with U-shaped fasteners.

The application of the paint or decorative sheet is performed according to the standard application specifications for the paint or decorative sheet to be used.

It should be noted that the shutter gate 100 of the embodiment can be put into practice even if its configuration is changed to the following form.

The shutter gate 100 of the embodiment was used as the shutter gate 100 of the garage for storing the vehicle, but it can also be used as the shutter gate 100 connected to the self-supporting wall surrounding the building.

In the shutter gate 100 of the embodiment, a square steel pipe with a side of 100 mm was used for the metal frames (support frame 31, beam frame 32) forming the gate member 3. can be used as long as the gate structure member 3 has the strength to support the shutter housing portion 41. For example, metal frames, wooden pillars, and synthetic resin pillars of different materials, shapes, and sizes can be used. can also be used.

In the shutter gate 100 of the embodiment, the support frame 31 erected from the installation surface G and the two beam frames 32 are joined and integrated with the gate member 3. is used, but the left and right ends of the shutter housing portion 41 are directly joined to the support frames 31 erected from the installation surface G, and the beam frame 32 is omitted. Even the gate member 3 can be used.

In the shutter gate 100 of the embodiment, the lightweight panel 1 uses polystyrene foam (EPS), which is easily molded by foaming beads, but any lightweight panel can be used. Polymer foams and inorganic foams can be used as materials for the lightweight panel. As polymer foams, polystyrene foams, polyurethane foams, polyphenol foams, polyolefin foams (polyethylene foams, polypropylene foams), etc. can be used. As inorganic foams, aluminum hydroxide-based foams (Talbocell), cement-based foams (ALC (autoclaved lightweight aerated concrete)), and the like can also be used.

In the shutter gate 100 of the embodiment, the lightweight panel 1 used has an EPS foaming ratio of 50 times. can. If the EPS has an expansion ratio of less than 30 times, a large amount of resin (beads) is required, which may be uneconomical. On the other hand, when the EPS has an expansion ratio of more than 60 times, the strength is low, and there is a risk of plastic deformation when receiving an impact. More preferably, the expansion ratio of EPS is 40 to 55 times.

The notch recess 17 provided in the lightweight panel 1 of the embodiment has a width W in the thickness direction of 50 mm and a depth D in the plane direction of 60 mm, but the width W and the depth D are each 30 to 100 mm. can be done. This is because if the width W and the depth D are 30 to 100 mm, the inter-panel through-holes 18 formed by the cutout recesses 17 can be easily filled with the slurry of the bonding cement composition forming the bonding cement molding 23. be. If each of the width W and the depth D is less than 30 mm, the inter-panel through-hole 18 is narrow, and there is a possibility that the slurry filling property of the cement composition will be poor. On the other hand, when the width W and the depth D each exceed 100 mm, although the filling property of the slurry of the cementing composition is excellent, the amount of the cementing composition used increases, which may be uneconomical. More preferably, the width W and the depth D are each 40-90 mm, more preferably 50-80 mm.

Although an L-shaped angle with a side length of 50 mm is used for the support member 21 of the embodiment, an L-shaped angle with a side length of 40 to 50 mm can be used. Further, the support member 21 is not limited to this, and may be a flat bar, a reinforcing bar, a deformed reinforcing bar, a steel frame, etc., as long as they reinforce the cement molding 23. .

In the lightweight panel 1 of the shutter gate 100 of the embodiment, the lightweight panels 1 to be joined are joined to each other, and the caulking material 51 is used to close the space between the lightweight panels 1. However, if there is a gap between the lightweight panels 1 to be joined, , a panel made of the same material as that of the lightweight panel 1 is processed into a size to fill the gap, and the space between the lightweight panels 1 can be closed.

In the shutter gate 100 of the embodiment, the installation surface G is driven while the gate structure member 3 and the support member 21 are installed. It can also be installed. In this case, an embedding hole for embedding the support member 21 is provided using a vibrating drill or the like at a location on the installation surface G where the lightweight panel 1 is to be installed, and the support member 21 is erected in the embedding hole. A slurry of the cement composition can be used to fix the support member 21 . Further, it is also possible to line up hollow concrete blocks at the place where the lightweight panel 1 is installed on the installation surface G, and erect the support member 21 in the hollow.

Steel plates can be attached to the upper side and the rear side of the upper portion of the gate member 3 of the shutter gate 100 of the embodiment, that is, the upper side (ceiling side) and the rear side of the shutter accommodating portion 41 . According to this, the water resistance of the garage can be enhanced.

Other technical ideas understood from the shutter gate 100 of the embodiment will be described below.

In the shutter gate 100 of the embodiment, the 100 mm PVC flow test value (JASS 15 M-103) of the slurry of the cement composition forming the cement molding can be 125 to 250 mm.

According to this, since the 100-mm PVC flow test value of the slurry of the jointing cement composition filled in the through-holes is 125 to 250 mm, the slurry of the jointing cement composition has appropriate fluidity and flows into the through-holes. filling can be facilitated. For this reason, workability at the time of construction can be excellent.

Further, in the shutter gate 100 of the embodiment, the bonding cement composition may be a composition containing 100 parts by mass of cement-based non-shrinkage mortar, 20 to 100 parts by mass of cement, and 100 to 200 parts by mass of aggregate. can.

According to this, since the slurry of the bonding cement composition has appropriate fluidity, it can be easily filled into the through-holes. For this reason, workability at the time of construction can be excellent.

In the construction method of the shutter gate 100 of the embodiment, an embedding step of embedding a caulking material, or a filling panel and a caulking material, between the light weight panels is included as a process prior to the filling process. can be done.

According to this, the gap between the lightweight panels, that is, the gap in the through-hole can be filled, so that the slurry of the jointing cement composition can be prevented from leaking when the through-hole is filled with the slurry of the jointing cement composition. be able to.
