Description

[Technical Field]

[0001] The present invention relates to a carport. [Background Art]

[0002] A carport generally includes a support post installed on an installation surface, a frame connected to the support post, and a roofing material placed on the frame. The frame includes a vertical crosspiece connected to the support post, and a horizontal crosspiece arranged and fixed on the vertical crosspiece in a direction orthogonal to the vertical crosspiece. In a conventional carport, for example, as shown in FIG. 8, the end of a vertical crosspiece (vertical beam) 20 is connected to the upper side surface of a support post 12 (see Patent Document 1). [Prior Art Documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Patent No. 7429081 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] Stress from the vertical crosspiece (vertical beam) 20, which is loaded with the weight of a horizontal crosspiece (horizontal rail) 30, a roofing material (solar panel) 50, and the like, is constantly concentrated at the connecting portion between the upper side surface of the support post 12 and the end of the vertical crosspiece (vertical beam) 20, and unexpected enormous stress may concentrate in a short time due to strong wind or the like. For this reason, the connection between the upper side surface of the support post 12 and the end face of the vertical crosspiece (vertical beam) 20 has been firmly achieved with high-strength bolts and nuts. However, in this case, since the connection is made only on the upper side surface (one surface) of the support post 12 located in a direction substantially orthogonal to the installation surface, when unexpected enormous stress concentrates on the connecting portion in a short time, damage or the like occurs at the connecting portion, leading to a serious danger such as the roof falling, which has been a problem.

[0005] Therefore, the present invention aims to solve the aforementioned problems of the conventional approach and achieve the following objectives. Specifically, it aims to provide a safe carport with a simple structure that is easy to connect and maintain, even if an unexpectedly large amount of stress is concentrated at the connection point between the support column and the vertical rail in a short period of time, without causing damage to the connection point. [Means for solving the problem]

[0006] The means to solve the aforementioned problem are as follows: <1> It comprises a support column 100 installed at the installation site, a vertical crossbar body 205, a bracing member 210 integrated with the vertical crossbar body, a pair of vertical crossbars 200A, 200B connected to the support column facing each other, and a horizontal crossbar 300 fixed on the vertical crossbars. The end face of one end of the first vertical bar 200A in the pair of vertical bars is connected to (1) the end face 220 of one end of the second vertical bar 200B in the pair of vertical bars, (2) the top surface 130 of the support column 100, and (3) the side surface 140 near the top surface of the support column 100. The end face of one end of the second vertical bar 200B is connected to (1) the end face 220 of one end of the first vertical bar 200A, (2) the top surface 130 of the support column 100, and (3) the side surface 140 near the top surface of the support column 100. This carport has the following characteristics: The aforementioned <1> In the carport described above, one end of the first vertical rail 200A is connected to (1) one end of the second vertical rail 200B, (2) the top surface (upper surface) 130 of the support column 100, and (3) the side surface 140 near the top surface (upper surface) of the support column 100, and one end of the second vertical rail 200B is connected to (1) one end of the first vertical rail 200A, (2) the top surface (upper surface) 130 of the support column 100, and (3) the side surface 140 near the top surface (upper surface) of the support column 100. Therefore, not only is the structure simple and easy to maintain, but the end face of one end of the first vertical batten 200A or the second vertical batten 200B is connected not just to one surface, but to three surfaces located at different positions: (1) the end face of one end of the second vertical batten 200B or the first vertical batten 200A, (2) the top surface (upper surface) 130 of the support column 100, and (3) the side surface 140 near the top surface (upper surface) of the support column 100. As a result, even if an unexpectedly large amount of stress is concentrated in the connection between the first vertical batten 200A or the second vertical batten 200B and the support column 100 in a short period of time, damage will not occur at the connection, and serious dangers such as the roof falling will be effectively prevented.

[0007] <2> In the first vertical bar 200A and the second vertical bar 200B, an L-shaped notch is formed near the approximate center of the end face 220 on one end that connects to the first vertical bar 220A or the second vertical bar 200B, when the first vertical bar or the second vertical bar is viewed from the side. An exposed surface 230 that is located substantially perpendicular to the end face 220 and is continuous with the end face, The exposed surface 230 has an inner end surface 240 which is located substantially perpendicular to the exposed surface and is continuous with the exposed surface and located inside the end surface, <1> This is the carport described in [the document]. The aforementioned <2> In the carport described above, the L-shaped notches are formed on one end of the first vertical rail 200A and the second vertical rail 200B, and the end face 220 on one end, the exposed surface 230, and the inner end face 240 are formed in a continuous manner. As a result, the end face 220 on one end of the first vertical rail 200A and the end face 220 on one end of the second vertical rail 200B can be connected, the exposed surface 230 of the first vertical rail 200A or the second vertical rail 200B can be connected to the top surface 130 of the support column 100, and the inner end face 240 of the first vertical rail 200A or the second vertical rail 200B can be connected to the side surface 140 near the top surface of the support column 100. In other words, the first vertical batten 200A, the second vertical batten 200B, and the support column 100 can be connected by three connecting surfaces (three faces) located at different positions. As a result, even if an unexpectedly large amount of stress is concentrated in the connection between the first vertical batten 200A or the second vertical batten 200B and the support column 100 in a short period of time, damage will not occur at the connection point, and serious dangers such as the roof collapsing will be effectively prevented.

[0008] <3> The end face 220 of the first vertical bar 200A and the end face 220 of the second vertical bar 200B are connected. The exposed surface 230 of the first vertical bar 200A and the exposed surface 230 of the second vertical bar 200B are connected to the top surface 130 of the support column 100. The inner end face 240 of the first vertical bar 200A and the inner end face 240 of the second vertical bar 200B are connected to the side surface 140 near the top surface of the support column 100, <1> This is the carport described in [the document]. The aforementioned <3> In the carport described above, the end face 220 at one end of the first vertical rail 200A is connected to the end face 220 at one end of the second vertical rail 200B, the exposed surface 230 of the first vertical rail 200A or the second vertical rail 200B is connected to the top surface (upper surface) 130 of the support column 100, and the inner end face 240 of the first vertical rail 200A or the second vertical rail 200B is connected to the side surface 140 near the top surface (upper surface) of the support column 100. In other words, the first vertical batten 200A, the second vertical batten 200B, and the support column 100 are connected by three connecting surfaces (three faces) located at different positions from each other. As a result, even if an unexpectedly large amount of stress is concentrated in the connection between the first vertical batten 200A or the second vertical batten 200B and the support column 100 in a short period of time, damage will not occur at the connection point, and serious dangers such as the roof collapsing will be effectively prevented.

[0009] <4> The roofing material 400 is placed on the horizontal rail 300, <1> This is the carport described in [the document]. The aforementioned <4> In the carport described above, the roofing material 400 is stably placed on the horizontal rails 300, which are fixed to the first vertical rails 200A and the second vertical rails 200B that are connected to the support columns on three different sides. Therefore, even if the carport is subjected to sudden and enormous stresses such as strong winds or gusts, serious dangers such as the roofing material falling are effectively prevented. [Effects of the Invention]

[0010] According to the present invention, the aforementioned problems of the conventional method can be solved, and even if an unexpectedly large amount of stress is concentrated at the connection point between the support column and the vertical rail in a short period of time, no damage will occur at the connection point, and a safe carport can be provided with a simple structure that is easy to connect and maintain.

[0012] A carport according to an embodiment of the present invention will be described with reference to Figures 1 to 7. Figure 1 is a schematic perspective view showing one embodiment of the carport of the present invention. Figure 2 is a schematic explanatory diagram for explaining the connection between a support post and a vertical beam in one embodiment of the carport of the present invention. Figure 3 is a partially enlarged end view for explaining the connection between a support post and a vertical beam in the carport shown in Figure 2. Figures 4 to 7 are each partially enlarged perspective views for explaining the connection between a support post and a vertical beam in the carport shown in Figure 2. It should be noted that the present invention is not limited to the following one embodiment, and appropriate modifications and the like can be made according to the purpose, and the carport may further include other members such as a rainwater receiver, a decorative cover, and a reinforcing member that are appropriately selected as needed.

[0013] A carport 1 according to an embodiment of the present invention includes a support post 100 installed at an installation site, a pair of vertical beams 200A and 200B connected to the support post 100 facing each other relative to the support post 100, a horizontal beam 300 fixed onto the vertical beams 200A and 200B, and a roofing material (solar panel) 400 placed on the horizontal beam 300. In FIG. 1, the roofing material (solar panel) 400 is illustrated only on one side of the carport 1, and the illustration of the roofing material on the other side is omitted; in FIG. 2, the illustration of the roofing material (solar panel) 400 is omitted.

[0014] The support post 100 only needs to be installable at the installation site of the carport 1 such as the ground of a parking lot, and there are no particular restrictions on the size, number (quantity), etc., and can be appropriately selected according to the purpose. There are no particular restrictions on the material of the support post 100, and it can be appropriately selected according to the purpose. Examples thereof include metal, wood, ceramics, and the like. Among these, metal is preferable from the viewpoint of durability and strength. Examples of the metal include iron, steel, aluminum, aluminum alloy, stainless steel, and the like. There are no particular restrictions on the shape or structure of the support post 100, and it can be appropriately selected according to the purpose. Examples thereof include solid or hollow square prismatic columns, cylindrical columns, square tubular columns, prismatic columns, and the like. From the viewpoint of reducing the weight of the support post 100, for example, a void may be provided in a square prismatic column to reduce its volume; in this case, it is preferable to form a plurality of ribs or the like in order to maintain or improve mechanical strength. In the case of the support post 100 having an uneven surface, a cover material may be disposed on the surface. In FIG. 1, a cover material covering the surface is illustrated below the connection portion of the support post 100 with the vertical beams 200A and 200B.

[0015] The cover material has a corrosion prevention function of protecting the surface of the support post 100 from corrosion such as rust, a buffering function of preventing damage to a vehicle when the vehicle parked in the carport 1 comes into contact with the support post, and a decorative function of making the surface appear flat when a void or the like is formed in the support post 100 for the purpose of reducing the weight of the support post 100, the volume is reduced, and the surface is not flat, among other functions.

[0016] Vertical rails 200A and 200B can be connected to the support columns 100 and, as long as they can support the roof, there are no particular restrictions, and they can be appropriately selected according to the purpose. There are no particular restrictions on the material of the vertical supports 200A and 200B, and they can be appropriately selected according to the purpose, for example, metal, wood, ceramics, etc. Among these, metal is preferred in terms of durability and strength. Examples of the metal include iron, steel, aluminum, aluminum alloy, stainless steel, etc. There are no particular restrictions on the shape or structure of the vertical bars 200A and 200B, and they can be appropriately selected according to the purpose. Examples include solid or hollow rectangular prisms, cylindrical shapes, rectangular tubes, and rectangular prisms. Furthermore, from the viewpoint of reducing the weight of the vertical bars 200A and 200B, for example, a rectangular prism shape may be made with voids to reduce its volume. In this case, it is preferable to form multiple ribs to maintain or improve mechanical strength. If the surface of the vertical bars 200A and 200B is not flat, a cover material may be placed on the surface.

[0017] Each vertical support 200A and 200B comprises a vertical support body 205 and a bracing member 210 integrated with the vertical support body 205. The bracing member 210 has the following functions. Specifically, if the load of the horizontal rails 300, roofing material (solar panels) 400, etc., fixed and placed on the vertical rail body 205 is supported only by the vertical rail body 205, stress will concentrate at the connection point between the vertical rail body 205 and the support column 100, making it prone to damage. By providing a bracing member 210 whose intersection angle with the support column 100 is greater than the intersection angle between the support column 100 and the vertical rail body 205, the stress concentration at the connection point between the vertical rail body 205 and the support column 100 can be mitigated. The bracing member 210 not only has the function of mitigating stress concentration at the connection point between the vertical rail body 205 and the support column 100, but by being integrated with the vertical rail body 205, the number of parts can be reduced, and the connection point between the bracing member 210 and the support column 100 can be formed directly below the connection point between the vertical rail body 205 and the support column 100. By using vertical rails 200A and 200B, in which the vertical rail body 205 and the bracing member 210 are integrated, it is possible to effectively prevent damage to the connection between the vertical rails 200A and 200B and the support column 100, even though the structure of the carport 1 is simple, and to effectively prevent serious dangers such as the roof falling.

[0018] Furthermore, when vertical battens 200A and 200B, each having an integrated vertical batten body 205 and bracing member 210, are positioned on opposite sides via a support column 100, the bracing member 210 in vertical batten 200A and the bracing member 210 in vertical batten 200B form a so-called brace structure, connecting and transmitting the loads of the roofs on both sides. This cancels out the moments of the loads on the roofs on both sides, thereby reducing stress.

[0019] Each vertical bar 200A and 200B has an L-shaped notch formed near the center of the end face 220 on one end side, when viewed from the side, and has an exposed surface 230 that is continuous with the end face 220 and is located approximately perpendicular to the end face 200, and an inner end face 240 that is located approximately perpendicular to the exposed surface 230, is continuous with the exposed surface 230, and is located inside the end face 220.

[0020] In carport 1, the end face 220 of one end of vertical rail 200A is connected to the end face 220 of one end of vertical rail 200B, the exposed surface 230 of vertical rail 200A is connected to the top surface 130 of the support column 100, the exposed surface 230 of vertical rail 200B is connected to the top surface 130 of the support column 100, the inner end face 240 of vertical rail 200A is connected to the side surface 140 of the support column 100 near the top surface 130 of the support column 100, and the inner end face 240 of vertical rail 200B is connected to the side surface 140 of the support column 100 near the top surface 130 of the support column 100, thereby connecting vertical rails 200A and 200B to the support column 100. The connection is made by inserting bolt B through bolt hole A and fastening bolt B with a nut from the opposite side.

[0021] In carport 1, the vertical rail 200A is firmly connected to the support column 100 and the vertical rail 200B at three different surfaces: the end face 220 on one end, the exposed surface 230, and the inner end face 240. That is, the direction in which it is fixed with bolts and nuts, i.e., the connection direction, is not one direction as in conventional designs, but two directions: parallel to the exposed surface 230 and parallel to the end face 220 and the inner end face 240. Furthermore, the connection in the direction parallel to the exposed surface 230 is made not at one position, but at two positions: approximately the central axis position of the support column 100 and a lateral position of the support column 100.

[0022] As a result, even if an unexpectedly large amount of stress is concentrated in a short time at the connection between the vertical rail 200A or vertical rail 200B and the support column 100, the synergistic or complementary effects of the above-mentioned 1) three surfaces located at different positions, 2) two directions parallel to the exposed surface 230 and parallel to the end surface 220 and inner end surface 240, and 3) two positions in the direction parallel to the exposed surface 230, namely the approximate central axis position of the support column 100 and the lateral position of the support column 100, can effectively prevent damage to the connection and effectively prevent serious dangers such as the roof falling.

[0023] The horizontal battens 300 can be fixed onto the vertical battens 200A and 200B, and as long as they can support the roofing material (solar panels) 400, there are no particular restrictions, and they can be appropriately selected according to the purpose. There are no particular restrictions on the material of the horizontal bar 300, and it can be appropriately selected according to the purpose, for example, metal, wood, ceramics, etc. Among these, metal is preferred in terms of durability and strength. Examples of the metal include iron, steel, aluminum, aluminum alloy, stainless steel, etc. There are no particular restrictions on the shape or structure of the crossbar 300, and it can be appropriately selected according to the purpose. Examples include solid or hollow rectangular prisms, cylindrical shapes, rectangular tubes, and rectangular prisms. Furthermore, from the viewpoint of reducing the weight of the crossbar 300, for example, a rectangular prism shape may be made with voids to reduce its volume. In this case, it is preferable to form multiple ribs or the like in order to maintain or improve mechanical strength. If the surface of the crossbar 300 is not flat, a cover material may be placed on the surface.

[0024] The roofing material 400 is placed on the horizontal battens 300 and functions as a roof. There are no particular restrictions on its shape, structure, size, or material, and it can be appropriately selected according to the purpose. However, it is preferable to have solar panels. In this case, the carport 1 can be made into a solar carport capable of generating solar power. Examples of materials for the roofing material 400 include metal materials such as iron, aluminum, stainless steel, and titanium, or hard resins other than metal materials. Examples of the hard resin materials include polyvinyl chloride resin (PVC), polystyrene resin (PS), acrylonitrile-butadiene-styrene copolymer (ABS) resin, and polymethyl methacrylate (PMMA) resin.

[0025] In carport 1, (A) vertical rails 200A and 200B each have a vertical rail body 205 and a bracing member 210 integrated with the vertical rail body 205, (B) one end face 220 of vertical rail 200A and one end face 220 of vertical rail 200B are connected, the exposed surface 230 of vertical rail 200A and the top surface (upper surface) 130 of the support column 100 are connected, and the exposed surface 230 of vertical rail 200B and the support column 100 are connected. Except for the fact that the column top surface (upper surface) 130 is connected to the column, the inner end surface 240 of the vertical rail 200A is connected to the column side surface 140 of the column 100 near the column top surface (upper surface) 130, and the inner end surface 240 of the vertical rail 200B is connected to the column side surface 140 of the column 100 near the column top surface (upper surface) 130, thereby connecting the vertical rails 200A and 200B to the column 100, the structure can be the same as a known carport.

[0026] Carport 1 can be installed in parking lots of, for example, houses, factories, hospitals, city halls, universities, convenience stores, shopping malls, supermarkets, pachinko parlors, etc. [Explanation of symbols]
