Description

  The present invention relates to a reinforcing material that reinforces a hollow panel made of synthetic resin and a wall body using the same.

  In recent years, a hollow panel made of synthetic resin has been used as a daylighting outer wall material for taking light. Since the synthetic resin hollow panel is lighter than a daylighting outer wall material such as a glass block, a wide daylighting wall can be realized.

  FIG. 6 shows an example of a synthetic resin hollow panel used as a lighting outer wall material. The hollow panel 10 is a member that constructs a wall body by connecting a plurality of hollow panels, and is manufactured by extruding a lightly colored translucent resin. As shown in FIG. 6, the hollow panel 10 includes a plate-shaped panel main body 11, and a continuous convex portion 12 and a continuous concave portion 13 for connecting to the adjacent hollow panel 10 on both sides of the panel main body 11. It has. The panel body 11 of the hollow panel 10 has a front surface 14 and a back surface 15, and a large number of panel hollow portions 17 are formed by providing vertical, horizontal, and diagonal partition walls 16 between the front surface 14 and the back surface 15. .

  The continuous protrusion 12 has a hollow shape with a slightly expanded tip, and is formed over the entire length of the hollow panel 10 on one side of the hollow panel 10. The continuous recess 13 is provided on the side opposite to the side where the continuous protrusion 12 is located, and is formed in a shape corresponding to the continuous protrusion 12. The continuous recesses 13 can be fitted with the adjacent convex portions 12 of the hollow panels by press-fitting the continuous convex portions 12 of the adjacent hollow panels from the side (direction A in FIG. 6). It has become. Since the hollow panel 10 includes the continuous protrusions 12 and the continuous recesses 13, the hollow panels can be easily connected to each other, and thereby, walls having various dimensions can be constructed.

  However, when the wall body is constructed by connecting only the hollow panels 10 made of synthetic resin, the strength may be insufficient. Therefore, conventionally, as shown in Patent Document 1, for example, a reinforcing material is inserted into the panel hollow portion 17 from above or below the hollow panel 10 to improve the strength of the hollow panel 10 or the wall body constructed thereby. It was.

It is a perspective view which shows the structure of a hollow panel.

  Hereinafter, preferred embodiments of a reinforcing member and a wall according to the present invention will be described with reference to the drawings. However, it should be noted that the technical scope of the present invention is not limited to these embodiments, but extends to the invention described in the claims and equivalents thereof.

  FIG. 1 is a perspective view showing a first embodiment of a reinforcing member 20 according to the present invention. FIG. 2 is a cross-sectional view showing a state where the reinforcing member 20 and the hollow panel 10 shown in FIG. 1 are connected.

  The reinforcing material 20 of the present embodiment is a reinforcing material that reinforces the above-described synthetic resin hollow panel 10 and can be connected to the pair of hollow panels 10. Hereinafter, in order to distinguish a pair of hollow panels 10, it is set as the hollow panels 10a and 10b from the left of the drawing, and the constituent members of each hollow panel will be described with corresponding alphabets.

  The configuration of the reinforcing material 20 will be described. As shown in FIG. 1, the reinforcing member 20 is fitted into a long main body 30 formed to the same length as the length L of the hollow panels 10 a and 10 b and a continuous recess 13 a of the hollow panel 10 a. The fitting part 40 and the 2nd fitting part 50 fitted to the continuous convex part 12b of the hollow panel 10b are provided. The main body 30 includes a front surface 31, a back surface 32, and a pair of side portions 33 and 34, and the first fitting portion 40 is located on one side portion 33 of the main body 30. The second fitting portion 50 is located on the other side portion 34 of the main body 30.

  Further, the reinforcing member 20 includes a first extending portion 41 extending outward in the width direction from a corner portion where the back surface 32 and the side portion 33 intersect, and the first extending portion 41 and the first fitting portion are provided. A first groove 42 is formed between the first groove 42 and the first groove 42. As will be described in detail later, when the hollow panel 10a and the reinforcing member 20 are connected, the first extension part 41 and the first groove part 42 are connected to the structure part of the building by being combined with the side part of the hollow panel 10a. For the purpose of forming a dovetail.

  In addition, the reinforcing member 20 includes a second extending portion 51 that extends from the corner where the back surface 32 and the side portion 34 cross each other in the width direction and in the opposite direction of the first extending portion 41. A second groove portion 52 is formed between the second extension portion 51 and the second fitting portion 50. Similarly to the first extension part 41 and the first groove part 42, the second extension part 51 and the second groove part 52 are combined with the side part of the hollow panel 10b to form a dovetail groove.

  The thickness direction is a direction perpendicular to the longitudinal direction of the reinforcing member 20 and means a direction from the front surface 31 toward the back surface 32 (see arrow E in FIG. 1). Further, the width direction means a direction perpendicular to the longitudinal direction of the reinforcing material 20 and parallel to the front surface 31 of the reinforcing material 20 (see arrow F in FIG. 1).

  Next, the 1st fitting part 40 is demonstrated. As shown in FIG. 1, the first fitting portion 40 has a convex shape with a bulging tip, and is formed in a hollow shape. The shape of the first fitting portion 40 is the same shape as the continuous protrusion 12b of the hollow panel 10b. Since the first fitting part 40 is hollow, the first fitting part 40 can be elastically deformed. Therefore, the 1st fitting part 40 can be press-fitted and fitted in the continuous recessed part 13a of the hollow panel 10a from the side (A direction of FIG. 1) of the hollow panel 10a. Even if the first fitting portion 40 is not elastically deformed, the first fitting portion 40 is connected to the hollow panel 10a as long as the continuous recess 13a of the hollow panel 10a can be elastically deformed. It is also possible to press fit from the side of the hollow panel 10a into the installation recess 13a.

  Next, the 2nd fitting part 50 is demonstrated. As shown in FIG. 1, the second fitting portion 50 has a concave shape corresponding to the convex shape of the first fitting portion 40 and includes the continuous convex portion 12 b of the hollow panel 10 b. It is possible. The shape of the second fitting portion 50 is the same shape as the continuous concave portion 13a of the hollow panel 10a, and the continuous convex portion 12b of the hollow panel 10b can be press-fitted from the side to be fitted. Note that the width H1 of the base portion of the second fitting portion 50 is narrower than the width H2 of the central portion of the second fitting portion 50, and the continuous protrusion 12b once swells due to the swelling of the tip portion. It is difficult for the second fitting portion 50 to come off.

  Next, the main body 30 of the reinforcing member 20 of this embodiment will be described.

  FIG. 2 is a cross-sectional view showing a state in which the reinforcing member 20 and the hollow panels 10a and 10b are connected.

  As shown in FIG. 2, a hollow portion 36 is formed in the main body 30 of the reinforcing member 20 of the present embodiment. By making the main body 30 hollow, the reinforcing material 20 can be produced at a low cost and at a low cost. The hollow portion 36 is a space surrounded by the front surface 31, the back surface 32, the side portion 33, the second fitting portion 50, and the partition wall 35, and is reinforced by inserting and attaching an auxiliary member 37 to the hollow portion 36. The strength of the material 20 can be adjusted as necessary. FIG. 2 shows a case where a member having an L-shaped cross section is attached as an example of the auxiliary member 37. In addition, a plate-like member or a member having a U-shaped cross section can be inserted and attached as the auxiliary member 37. Further, depending on the shape of the hollow portion 36 of the main body 30, a B-shaped member may be inserted (see FIG. 4). In order to increase the strength of the reinforcing member 20, the main body 30 may be solid.

  The auxiliary member 37 is screwed by a screw 38 that inserts the distal end portion of the second fitting portion 50 and the partition wall 35. Since the screw 38 is screwed from the inside of the second fitting portion 50, the screw head is concealed by the second fitting portion 50, and in particular, after the reinforcing member 20 and the hollow panel 10b are connected, the screw is externally screwed. I can't see my head. Therefore, the strength of the reinforcing member 20 can be improved by the auxiliary member 37 without changing the appearance of the wall body. The material of the auxiliary member 37 is not particularly limited, but is preferably made of metal, particularly aluminum from the viewpoint of rigidity and processability. The auxiliary member 37 may be made of resin. In addition to the hollow portion 36 of the main body 30, the auxiliary member 37 can be provided outside the back surface 32 of the reinforcing material 20, for example. In this case, the design of the wall body as viewed from the front side is not lowered, and the trouble of inserting the auxiliary member 37 into the hollow portion 36 can be saved. This is particularly effective when the main body 30 is long.

  When the reinforcing member 20 of the present embodiment is connected to the hollow panels 10a and 10b, as shown in FIG. 2, the front surface 31 of the reinforcing member 20 and the front surfaces 14a and 14b of the hollow panels 10a and 10b form a surface having no step. To do. That is, the front surface 31 of the reinforcing member 20 is formed to be flush with the front surfaces 14a and 14b of the hollow panels 10a and 10b. Even if the reinforcing member 20 is inserted and connected between the pair of hollow panels 10a and 10b, a surface having no step is constructed, so that the design of the wall body is not lowered by the reinforcing member 20.

  The thickness of the reinforcing member 20 of the present embodiment, that is, the distance H3 between the front surface 31 and the back surface 32 of the main body 30 is the same as the thickness of the hollow panels 10a and 10b. However, in order to improve the strength of the reinforcing member 20, the thickness of the reinforcing member 20 may be made larger than the thickness of the hollow panels 10a and 10b. In this case, while the front surface 31 of the reinforcing material 20 and the front surfaces 14a and 14b of the hollow panels 10a and 10b are flush with each other, the back surface 32 of the reinforcing material 20 extends in the thickness direction (C direction in FIG. 2) and is hollow. You may make it protrude from the back surfaces 15a and 15b of panel 10a, 10b. Further, the reinforcing member 20 may be enlarged in the width direction.

  Next, the 1st extension part 41 and the 1st groove part 42 of the reinforcing material 20 are demonstrated.

  As shown in FIG. 2, the hollow panels 10 a and 10 b to which the reinforcing member 20 of the present embodiment is connected are extended to the outside in the width direction from the corners where the side portions of the hollow panels and the back surfaces 15 a and 15 b intersect. Parts 18a and 18b, and panel side groove parts 19a and 19b formed between the panel side extending parts 18a and 18b and the continuous convex part 12b or the continuous concave part 13a. Originally, a pair of hollow panels 10a and 10b are continuously provided, so that dovetail portions having a T-shaped cross section are formed by the panel side extending portions 18a and 18b and the panel side groove portions 19a and 19b. The coupling member 70 shown in FIG. 2 is an example of a member that couples the wall body and the building structural portion. By inserting a mounting bracket 72 having a T-shaped cross section at the tip of the coupling member 70 into the dovetail portion. The coupling member 70 and the wall body were coupled, and the wall body could be attached to the building structure.

  The reinforcing member 20 is joined to the hollow panels 10a and 10b so that the wall member can be attached to the structural part of the building even when the wall member is configured using the reinforcing member 20 of the present embodiment. As a result, dovetail grooves 60a and 60b are formed. As described above, the reinforcing member 20 of the present embodiment includes the first extending portion 41 extending outward in the width direction from the corner portion where the back surface 32 and the side portion 33 intersect, and the first extending portion. A first groove portion 42 is formed between 41 and the first fitting portion 40. That is, the reinforcing member 20 includes a first extending portion 41 facing the panel side extending portion 18 a and a first groove portion 42 corresponding to the panel side groove portion 19 a over the entire longitudinal direction of the side portion 33. ing. When the hollow panel 10a and the reinforcing member 20 are coupled, the panel side extending portion 18a and the first extending portion 41 face each other and are spaced apart from each other, and the panel side groove portion 19a and the panel side extending portion are arranged. A dovetail groove portion 60 a is formed by the protruding portion 18 a, the first extending portion 41, and the first groove portion 42.

  In addition, the reinforcing member 20 includes a second extending portion 51 that extends from the corner where the back surface 32 and the side portion 34 cross each other in the width direction and in the opposite direction of the first extending portion 41. A second groove portion 52 is formed between the second extension portion 51 and the second fitting portion 50. That is, the reinforcing member 20 includes a second extending portion 51 facing the panel side extending portion 18 b and a second groove portion 52 over the entire longitudinal direction of the side portion 34. When the hollow panel 10b and the reinforcing member 20 are coupled, the panel side extension 18b and the second extension 51 are opposed to each other and are spaced apart from each other, and the panel side groove 19b, the panel side extension A dovetail groove portion 60 b is formed by the protruding portion 18 b, the second extending portion 51, and the second groove portion 52.

  As described above, when the reinforcing member 20 is connected to the hollow panels 10a and 10b, two T-shaped dovetail portions 60a and 60b are formed. As in the conventional case, the wall body and the structural portion of the building may be joined by inserting a T-shaped mounting bracket 72 into either one of the dovetail groove portions 60a and 60b. The wall member may be coupled to the structure portion by inserting the mounting bracket 72 into both the dovetail portions 60a and 60b.

  The material of the reinforcing member 20 and the main body 30 is not particularly limited, but it is preferable that the reinforcing member 20 and the main body 30 are made of a material having higher strength than the material of the hollow panel 10. From the viewpoint of rigidity and ease of processing, the reinforcing member 20 is preferably made of metal, particularly aluminum. In this embodiment, the reinforcing material 20 is formed by extrusion molding of an aluminum material.

  In addition, although the hollow panel 10 connected with the reinforcing material 20 of this embodiment is a product made from a synthetic resin, as a specific synthetic resin, it is polycarbonate resin, an acrylic resin, a polyester resin, a polyvinyl chloride resin, and these resin is glass. Examples thereof include light-transmitting synthetic resins such as reinforced resins containing fibers. The hollow panel 10 may be formed of a material other than a synthetic resin, an inorganic material such as cement, calcium carbonate, calcium silicate, ceramics, or the like, and a material in which reinforcing bars, glass fibers, or aramid fibers are contained in these inorganic materials. .

  Next, the wall body 100 constructed using the plurality of hollow panels 10 and the reinforcing material 20 will be described.

  FIG. 3 is a front view showing a wall body 100 constructed using a plurality of hollow panels 10 and a reinforcing material 20.

It arrange | positions over the whole longitudinal direction of a part. Subsequently, the reinforcing member 20 and the hollow panel 10b are joined by press-fitting and fitting the continuous protrusion 12b of the hollow panel 10b into the second fitting portion 50 of the reinforcing member 20. As described above, the wall body 100 is constructed by alternately connecting the plurality of hollow panels 10 and the reinforcing members 20. When the hollow panel 10 is reinforced by the reinforcing material 20, the strength of the wall body 100 is also improved. As shown in FIG. 3, the wall body 100 is completed by providing frame members 81 to 84 on the top, bottom, left, and right of the wall body 100. Since the upper and lower ends of the reinforcing member 20 are in direct contact with the frame members 81 and 83, the reinforcing member 20 is sandwiched between the frame members 81 and 83. By fixing the reinforcing member 20 from the outside of the frame members 81 and 83 with screws or the like, the reinforcing member 20 and the frame members 81 and 83 are integrated, whereby the hollow panel 10 and the wall body 100 have higher strength. Can be obtained. In the present embodiment, the wall body 100 is constructed by alternately connecting the hollow panels 10 and the reinforcing members 20, but it is not always necessary to alternately connect the hollow panels 10 and the reinforcing material 20, and according to the strength required for the wall body 100. Thus, the reinforcing material 20 may be appropriately provided between the hollow panels 10. For example, every other reinforcing material 20 may be provided.

  Next, modifications 1 and 2 of the first embodiment described above will be described below with reference to the drawings. Regarding the points that are not particularly described with respect to the modified examples, the description in detail regarding the above-described first embodiment is applied as appropriate. Moreover, the same code | symbol is attached | subjected to the same component.

  The reinforcing member 21 which is the first modification of the first embodiment includes a main body 31, a first fitting portion 40, and a second fitting portion 50, similarly to the reinforcing member 20. However, the second fitting portion 50 of the reinforcing member 21 is different in that it has the same shape as the convex shape, that is, the continuous convex portion, in accordance with the shape of the continuous concave portion 13c of the hollow panel 10c to be connected. ing. Thus, both the 1st fitting part 40 and the 2nd fitting part 50 of the reinforcement material by this invention may have the same convex shape as a continuous convex part. The reinforcing material 21 is adapted to the shape of the continuous recessed portion 13c of the hollow panel 10 to which the second fitting portion 50 is coupled, and the other effects are the same as those of the reinforcing material 20 described above.

  FIG. 5 is a cross-sectional view showing the reinforcing member 22 of Modification 2 of the first embodiment.

  The reinforcing member 22 which is the second modification of the first embodiment includes a main body 30, a first fitting portion 40, and a second fitting portion 50, similarly to the reinforcing member 20. However, the first fitting portion 40 of the reinforcing member 22 is different in that it has the same concave shape as the continuous concave portion of the hollow panel 10 in accordance with the continuous convex portion 12d of the hollow panel 10d to be connected. Yes. Thus, both the 1st fitting part 40 and the 2nd fitting part 50 of the reinforcing material by this invention may have the same concave shape as a continuous recessed part. A dovetail groove 61 having a cross-sectional shape similar to the dovetail grooves 60a and 60b is formed in the center of the back surface 32 along the longitudinal direction.

  In Modification 2, since both the first fitting portion 40 and the second fitting portion 50 have a concave shape, the width of the main body 30 of the reinforcing member 22 is wider than that of the reinforcing member 20. Yes. Therefore, the strength is higher than that of the reinforcing member 20 with respect to the stress applied in the width direction (for example, the D direction in FIG. 5). Moreover, since there are three hollow portions 36, more auxiliary members 37 that reinforce the reinforcing material 22 can be attached, and the strength can be further improved. Moreover, by providing the dovetail part 61 in the center, it becomes possible to couple | bond with the structural part of a building via a coupling member only with the reinforcing material 22. FIG.

  The present embodiment has been described above with reference to the drawings. If the reinforcing material of this embodiment is used, it is possible to attach a reinforcing material from the side of a hollow panel. Therefore, as compared with the conventional reinforcing method in which a reinforcing material is inserted from above or below, it is possible to easily reinforce the hollow panel and the wall body, and the workability for constructing the wall body is improved. Play. Further, since the reinforcing material is attached to the outside of the hollow panel, a reinforcing material having high strength can be provided in the hollow portion of the hollow panel without limiting the size of the reinforcing material as in the prior art.

  In addition, although the reinforcement material of this embodiment was provided with the two fitting parts (a 1st fitting part and a 2nd fitting part) which face the mutually opposite side, it reinforces the hollow panel located in the end of a wall body If it does, the fitting part of a reinforcing material may be one (namely, only 1st fitting part).
