Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure installation frame which sufficiently withstands both vertical force and horizontal force, is low in parts count, and contributes to cost reduction. <P>SOLUTION: According to the structure of the structure installation frame, when a load is applied from a mounting bar 4 to a front bracket 2, a force based on the load is borne not only by bolts 14, 16 for rigidly connecting between a front end 4a of the mounting bar 4 and the front bracket 2, but also even by internal peripheral abutting portions 2k of side plates 2b, 2c of the front bracket 2, on which an upper edge 4d of the front end 4a of the mounting bar 4 is abutted, and therefore the force is borne by a plurality of points, i. e. the bolts 14, 16, and the internal peripheral abutting portions 2k of the respective side plates 2b, 2c. Therefore when compared with the case where a force applied to the front bracket 2 is borne only by bolts, the load-carrying capacity of a connection portion between the mounting bar 4 and the front bracket 2 is enhanced. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a structure installation stand suitable for installing a flat structure such as a solar cell module on the ground or a flat roof, and an assembling method thereof.

  In this type of conventional frame, in order to support the solar cell module toward the sun, the mounting beam is tilted and fixed with respect to the foundation surface such as the ground or a flat roof. The solar cell module is supported on the top. For example, as shown in FIG. 27, the two base blocks 101 and 102 are spaced apart and fixed, the tip 103a of the mounting beam 103 is connected and fixed to the front base block 101, and the upper end 104a of the vertical beam 104 is fixed. In addition to being connected near the center of the mounting beam 103, the lower end 104 b of the vertical beam 104 is connected to the rear foundation block 102, and the mounting beam 103 and the rear foundation block 102 are connected by the vertical beam 104. Thus, the mounting bar 103 is tilted and fixed. A plurality of such mounting bars 103 are arranged side by side, and a solar cell module is mounted on and supported by these mounting bars 103.

Alternatively, four legs are erected on the ground or a flat roof, a rectangular frame is fixedly supported on these legs, and a solar cell module is placed on the frame, The two legs are shorter than the two legs on the rear side, the frame is inclined, and the light receiving surface of the solar cell module is substantially directed in the incident direction of sunlight (see Patent Documents 1 and 2). reference).

  By the way, when supporting a flat structure such as a solar cell module, since the wind pressure received by the structure is large, not only the load of the structure itself but also the load generated from the wind pressure must be able to withstand sufficiently. Don't be.

  For example, in the structure in which four legs are erected as in Patent Documents 1 and 2 and the solar cell module is supported on these legs, when a load resulting from a structure load or wind pressure acts, Since vertical and horizontal forces act on the legs of the legs, the legs must be firmly supported so that the legs do not fall down, and bolts and reinforcing brackets for fixing and supporting the legs It was necessary to increase the number. However, this increased the number of parts and the number of assembling steps, making it difficult to assemble on-site and increasing the cost.

  On the other hand, as shown in FIG. 27, in the triangular structure in which the mounting beam 103, the vertical beam 104, and the base surface are combined in a triangle, the vertical and horizontal directions can be obtained without particularly increasing the number of parts. It can withstand enough force.

  In order to maintain the original strength of such a triangular structure sufficiently high, the strength of the connection of the mounting beam, the vertical beam, and the foundation surface as well as the strength of the mounting beam and the vertical beam are sufficient. Need to be high. In particular, since a large force acts on both the vertical direction and the horizontal direction at the front end of the mounting bar, it is necessary to increase the connection strength of the front end.

  However, if the number of bolts and reinforcing metal fittings is increased in order to increase the connection strength between the tip of the mounting bar and the bracket, the number of parts and assembly man-hours increase as in Patent Documents 1 and 2. As a result, the assembly work at the site becomes difficult and the cost increases.

  Therefore, the present invention has been made in view of the above-described conventional problems, and can sufficiently withstand any force in the vertical direction and the horizontal direction, has a small number of parts, and can keep costs low. It is an object of the present invention to provide a structure installation stand and an assembly method thereof.

  In order to solve the above-mentioned problems, a structure installation stand of the present invention includes a front bracket fixed to a foundation surface and a mounting bar on which the structure is mounted. The structure installation stand in which the tip side of the inclined mounting bar and the side of the front bracket are overlapped and the tip of the mounting bar and the front bracket are fastened by bolts penetrating these side surfaces. The front bracket has a contact portion that contacts the upper edge or the upper surface of the tip portion of the mounting beam, and the upper edge or upper surface of the tip portion of the mounting beam serves as a contact portion of the front bracket. By the contact, movement of the mounting bar around the bolt is prevented.

  In addition, at least the front end of the mounting bar has a U-shaped or hat-shaped cross-sectional shape, and the front bracket is a side plate of the U-shaped or hat-shaped front end of the mounting bar. Each of the side plates that come into contact with the upper edge of the U-shaped or hat-shaped tip or an abutting portion that comes into contact with the upper surface, and the bolt is a U-shaped or hat-shaped tip of the mounting beam. The U-shaped or hat-shaped tip and the front bracket are fastened by passing through each side plate of the front part and each side plate of the front bracket, and the contact part of the front bracket is the U-shaped or hat of the mounting beam. It is in contact with the upper edge or upper surface of the die tip from above.

  Further, the contact portion of the front bracket is a recess formed in each side plate of the front bracket, and the upper edge or upper surface of the U-shaped or hat-shaped tip of the mounting bar is the front bracket. It enters into the recess of each side plate and contacts.

  In addition, the recess of each side plate of the front bracket is an arcuate or straight cut groove formed in each side plate of the front bracket, and the upper side of the U-shaped or hat-shaped front end portion of the mounting rail The edge or upper surface enters and contacts the cut groove of each side plate of the front bracket.

  In addition, a rear bracket that is spaced from the front bracket and fixed to the base surface, and a vertical beam that connects and connects the mounting beam and the rear bracket are provided.

  On the other hand, the method of assembling the structure installation stand according to the present invention includes a step of separating the front bracket and the rear bracket and fixing them to the foundation surface, and the rear of the vertical beam in a state where the vertical beam is inclined with respect to the foundation surface. With the process of fixing to the bracket and the mounting beam placed on the vertical beam, the mounting beam is tilted with respect to the foundation surface, and the tip side of the mounting beam and the front bracket side are overlapped Fasten the tip of the mounting bar and the front bracket with bolts that penetrate these side surfaces, and bring the upper edge or upper surface of the tip of the mounting bar into contact with the contact part of the front bracket. And a step of preventing movement of the mounting bar.

  According to the structure installation stand of the present invention, the tip side surface of the inclined mounting bar and the side surface of the front bracket are overlapped, and the front end part of the mounting beam and the front bracket are connected by bolts penetrating these side surfaces. It is concluded. Further, the upper edge or upper surface of the tip of the mounting bar comes into contact with the contact portion of the front bracket, and the movement of the mounting bar around the bolt in the direction perpendicular to the water flow direction is prevented. Therefore, the load acting on the mounting bar is not only received by the bolt that fastens the front end of the mounting bar and the front bracket, but also the front bracket where the upper edge or upper surface of the front end of the mounting bar abuts. The contact portion is also received and distributed to a plurality of locations of the bolt and the contact portion. For this reason, the load resistance of the connection part between the mounting bar and the front bracket is improved as compared with a case where all the loads acting on the mounting bar are received at only one place of the bolt. Moreover, the number of parts and assembly man-hours do not increase.

  For example, the tip of the mounting bar has a U-shaped or hat-shaped cross-sectional shape. Such a cross-sectional shape improves the strength of the tip. In addition, the bolt passes through each side plate of the U-shaped or hat-shaped tip of the mounting bar and each side plate of the front bracket, and fastens the U-shaped or hat-shaped tip and the front bracket. Furthermore, the contact portion of the front bracket is in contact with the upper edge or upper surface of the U-shaped or hat-shaped tip of the mounting beam from above, and is perpendicular to the water flow direction of the mounting beam around the bolt. Prevent upward movement.

  For example, the contact portion of the front bracket is a respective recess formed in each side plate of the front bracket, and the upper edge or upper surface of the U-shaped or hat-shaped tip of the mounting bar is each of the front bracket. It enters into the recess of the side plate and contacts. The recess of each side plate of the front bracket is a circular or straight cut groove or the like.

  In addition, since it includes a rear bracket spaced apart from the front bracket and fixed to the foundation surface, and a vertical beam for connecting and connecting the mounting beam and the rear bracket, the mounting beam, the vertical beam, and the foundation surface A triangular structure frame can be constructed. In such a triangular structure, even if a load acts on the mounting bar from any direction, the load can be distributed and received. For this reason, even if a flat structure such as a solar cell module is placed and fixed on the mounting bar and a load based on the structure itself or a wind pressure is applied, these loads are not affected. It can withstand it.

  On the other hand, according to the assembling method of the present invention, it is possible to assemble a frame having a triangular structure including a mounting bar, a vertical bar, and a base surface. In addition, the front end of the mounting bar and the front bracket are fastened by bolts, and the upper edge or upper surface of the front end of the mounting bar is brought into contact with the contact portion of the front bracket. The movement of the mounting bar in the direction perpendicular to the water flow direction can be prevented, and the load resistance of the connection portion between the mounting bar and the front bracket is improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing an embodiment of the structure installation stand of the present invention. The structure installation stand 1 of this embodiment is for installing flat structures, such as a solar cell module, on the ground or a flat roof. In this gantry 1, the front bracket 2 and the rear bracket 3 are installed and fixed at a certain distance from a horizontal base surface such as the ground or a flat roof, and the front end 4 a of the mounting bar 4 is connected and fixed to the front bracket 2. The first vertical beam 5 is interposed and fixed between the rear bracket 3 and the center of the mounting beam 4, and the second vertical beam 6 is fixed to the lower end 5 a of the first vertical beam 5 and the mounting beam 4. It is fixed between the ends.

  Only the front end 4a of the mounting bar 4 has a U-shaped cross-sectional shape, and a hat-shaped cross-sectional shape in the range from the vicinity of the front end 4a to the rear end. In addition, the first and second vertical bars 5 and 6 have a U-shaped cross-sectional shape only at the upper end portion thereof, and have a hat-shaped cross-sectional shape in the range from the vicinity of the upper end portion to the lower end.

  Each of the front bracket 2, the rear bracket 3, the mounting bar 4, and the first and second vertical bars 5 and 6 is obtained by cutting and bending a metal plate such as a plated steel plate.

  2 and 3 are a perspective view and a side view showing a connection structure of the front bracket 2 with respect to the tip end portion 4a of the mounting bar 4. FIG. FIG. 4 is a perspective view showing a connection structure when the front bracket 2 is viewed from the back side. FIG. 5 is a perspective view showing the front bracket 2.

  The front bracket 2 includes a bottom plate 2a, side plates 2b and 2c that are bent and raised at both sides of the bottom plate 2a, and reinforcing portions 2d and 2e that are bent and raised at the front and rear of the bottom plate 2a. A plurality of holes 2 f are formed in the bottom plate 2 a of the front bracket 2. Also, each side plate 2b, 2c is formed with a respective screw hole 2g, 2h and a respective arc groove 2i, 2j, and each arc groove 2i, 2j is located in front of each screw hole 2g, 2h. ing.

  At least one bolt 11 is passed through the washer 12, and further passed through the hole 2f of the bottom plate 2a of the front bracket 2 and screwed into the base surface, whereby the front bracket 2 is fixed to the base surface.

  The front end 4a of the mounting bar 4 has a U-shaped cross-sectional shape, and the inner width of each side plate 4b, 4c of the front end 4a is the same as the outer width of each side plate 2b, 2c of the front bracket 2. Or slightly wider than the outer width, the side plates 2b and 2c of the front bracket 2 are sandwiched inside the side plates 4b and 4c of the tip 4a, and the side plates 4b and 4c of the tip 4a are forward. It is overlaid on each side plate 2b, 2c of the bracket 2.

  Then, the bolt 14 is passed through the washer 15, and is screwed into the screw hole 2g of the one side plate 2b of the front bracket 2 through the hole (not shown) of the one side plate 4b of the front end portion 4a. Is passed through the washer 17 and screwed into the screw hole 2h of the other side plate 2c of the front bracket 2 through the hole (not shown) of the other side plate 4c of the front end portion 4a. Thereby, the front end 4 a of the mounting bar 4 is connected and fixed to the front bracket 2.

  In a state where the mounting bar 4 is inclined with respect to the base surface, the upper edge 4d of the tip 4a of the mounting bar 4 enters the circular grooves 2i and 2j of the side plates 2b and 2c of the front bracket 2. The upper edge 4d of the tip portion 4a contacts the inner peripheral contact portion 2k of each circular groove 2i, 2j.

  In this state, the inner peripheral contact portion 2k of each side plate 2b, 2c of the front bracket 2 is in contact with the upper edge 4d of the front end portion 4a of the mounting bar 4 from above, and the front end part 4a of the mounting bar 4 Is about to move vertically around the water flow direction of the mounting rail 4 around the bolts 14 and 16, the upper edge 4d of the tip 4a of the mounting rail 4 is moved to the side plates 2b of the front bracket 2. The tip end 4a of the mounting bar 4 is prevented from moving in the direction perpendicular to the water flow direction by being pressed against the inner peripheral contact portion 2k of 2c.

  Therefore, when a load is applied from the mounting bar 4 to the front bracket 2, a force based on this load is applied by the bolts 14 and 16 that connect and fix the tip 4 a of the mounting bar 4 and the front bracket 2. In addition to being received, the bolts 14 and 16 and the side plates are also received at the inner peripheral contact portions 2k of the side plates 2b and 2c of the front bracket 2 with which the upper edge 4d of the tip 4a of the mounting bar 4 contacts. 2b and 2c are received in a plurality of locations as inner peripheral contact portions 2k. For this reason, compared with the case where the force which acts on the front bracket 2 is received only by the bolt, the load resistance of the connection portion between the mounting bar 4 and the front bracket 2 is improved. In particular, load resistance in the direction in which the upper edge 4d of the front end 4a of the mounting bar 4 is in contact with the inner peripheral contact portion 2k of each side plate 2b, 2c of the front bracket 2 (upward direction perpendicular to the water flow direction). Will improve. Moreover, the number of parts and assembly man-hours do not increase.

  Instead of forming the circular grooves 2i and 2j on the side plates 2b and 2c of the front bracket 2, the linear grooves 2m as shown in FIG. 6 may be formed. When the upper edge 4d of the tip portion 4a of the mounting bar 4 is inserted into these linear grooves 2m, the upper edge 4d of the tip portion 4a comes into contact with the inner peripheral contact portion 2k of each linear groove 2m, and is mounted. Not only is the movement of the mounting beam 4 upward in the direction perpendicular to the water flow direction, but also the rotation of the mounting beam 4 is prevented. For this reason, the mounting beam 4 can be supported in an inclined state with respect to the base surface by simply connecting and fixing the front end 4 a of the mounting beam 4 to the front bracket 2. When the first vertical beam 5 is connected and connected between the base surfaces to constitute the mounting frame 1, the first vertical beam 5, and the triangular structure installation stand 1 composed of the basic surface, the assembly work is performed. It becomes easy.

  Further, not only circular grooves and linear grooves but also other shapes of recesses are formed in the side plates 2b and 2c of the front bracket 2, and the contact portions of the recesses of the side plates 2b and 2c are located above the tip portion 4a. You may make it contact | abut to the edge 4d from the upper direction. Furthermore, a configuration in which a contact portion such as a circular groove, a straight groove, and a recess is in contact with the upper surface of the tip portion 4a instead of the upper edge 4d of the tip portion 4a may be employed.

  7 and 8 are a perspective view and a side view showing a connection structure of the rear bracket 3 to the lower end portion 5a of the first vertical rail 5. FIG. 9 is a perspective view showing the rear bracket 3 and the like.

  The rear bracket 3 includes a bottom plate 3a, side plates 3b that are bent and raised at both sides of the bottom plate 3a, and reinforcing portions 3d and 3e that are bent and raised at the front and rear of the bottom plate 3a. A plurality of holes 3 f are formed in the bottom plate 3 a of the rear bracket 3. Each side plate 3b has a screw hole 3g. Further, the front reinforcing portion 3d is bent obliquely in the middle thereof, and the inclined front end side is a receiving portion 3i.

  At least one bolt 21 is passed through the washer 22, and further passed through the hole 3f of the bottom plate 3a of the rear bracket 3 and screwed into the base surface, whereby the rear bracket 3 is fixed to the base surface.

  As shown in FIG. 1, only the upper end 5d of the first vertical cross 5 has a U-shaped cross-sectional shape, and has a hat-shaped cross-sectional shape in the range from the vicinity of the upper end 5d to the lower end. As shown in FIGS. 7 and 8, the inner width of each side plate 5 b of the first vertical rail 5 is set to be the same as or slightly wider than the outer width of each side plate 3 b of the rear bracket 3. At the lower end portion 5 a of the first vertical bar 5, the side plates 3 b of the rear bracket 3 are sandwiched inside the side plates 5 b, and the side plates 5 b are overlapped with the side plates 3 b of the rear bracket 3. Further, the lower side of each side plate 5 b is in contact with the receiving portion 3 i of the reinforcing portion 3 d of the rear bracket 3.

  In this state, the bolt 24 is passed through the washer 25 and screwed into the screw hole 3g of the one side plate 3b of the rear bracket 3 through the hole (not shown) of one side plate 5b of the lower end portion 5a of the first vertical bar 5. The other bolt (not shown) is also passed through a washer (not shown), and the other side plate 3b of the rear bracket 3 is passed through a hole (not shown) in the other side plate 5b of the lower end 5a. The screw hole 3g is screwed and fastened. As a result, the lower end 5 a of the first vertical beam 5 is connected and fixed to the rear bracket 3.

  At this time, at the lower end portion 5a of the first vertical beam 5, the lower side of each side plate 5b is received in contact with the receiving portion 3i of the reinforcing portion 3d of the rear bracket 3, so that the first vertical beam 5 is in contact with the base surface. It is supported in an inclined state.

  As shown in FIG. 1, the upper end 5 d of the first vertical beam 5 is inserted inside the center of the hat-shaped mounting beam 4, and two bolts 26 are formed in the holes on the side walls of the mounting beam 4. The upper end 5d of the first vertical bar 5 is connected and fixed near the center of the mounting bar 4 by being screwed into the screw holes on the respective side walls of the first vertical bar 5 and fastened.

  The second vertical beam 6 also has a U-shaped cross-section only at the upper end 6d, and has a hat-shaped cross-sectional shape in the range from the vicinity of the upper end 6d to the lower end. 6, the inner width of each side plate 6b is set to be the same as or slightly wider than the outer width of each side plate 5b of the first vertical rail 5. At the lower end 6 a of the second vertical beam 6, the side plates 5 b of the first vertical beam 5 are sandwiched between the side plates 6 b, and the side plates 6 b are overlapped with the side plates 5 b of the first vertical beam 5.

  Then, the bolt 31 is passed through the washer 32, and the screw hole (not shown) of one side plate 5b of the first vertical beam 5 is passed through the hole (not shown) of one side plate 6b of the lower end portion 6a of the second vertical beam 6. And the other bolt (not shown) is passed through a washer (not shown), and a hole (not shown) in the other side plate 6b of the lower end 6a of the second vertical beam 6 is inserted. ) And screwed into a screw hole (not shown) of the other side plate 5b of the first vertical beam 5 to be fastened. As a result, the lower end 6 a of the second vertical beam 6 is connected and fixed to the lower end 5 a of the first vertical beam 5.

  As shown in FIG. 1, the upper end 6 d of the second vertical beam 6 is inserted inside the vicinity of the rear end of the hat-shaped mounting beam 4, and two bolts 33 are provided on each side wall of the mounting beam 4. Through the hole, it is screwed into a screw hole on each side wall of the second vertical beam 6 and fastened, whereby the upper end portion 6 d of the second vertical beam 6 is connected and fixed near the rear end of the mounting beam 4.

  Here, when a load acts from the mounting beam 4 to the first vertical beam 5 or when a load acts from the mounting beam 4 to the first vertical beam 5 via the second vertical beam 6, The rear bracket in which the force based on the load is not only received by the two bolts 24 that fasten the lower end portion 5a of the first vertical beam 5 and the rear bracket 3, but the lower side of each side wall 5b of the first vertical beam 5 abuts. 3 receiving portions 3i are received in a distributed manner at a plurality of locations including two bolts 24 and the receiving portion 3i of the rear bracket 3. For this reason, compared with the case where the force which acts on the back bracket 3 is received only with the volt | bolt, the load resistance of the connection part between the 1st vertical cross 5 and the back bracket 3 improves. Moreover, the number of parts and assembly man-hours do not increase.

  Further, since the receiving portion 3i of the rear bracket 3 receives the lower side of each side plate 5b of the first vertical beam 5 from below, the downward movement of the first vertical beam 5 around each bolt 24 is prevented. . For this reason, the first vertical beam 5 can be supported in an inclined state simply by connecting and fixing the front end portion 5a of the first vertical beam 5 to the rear bracket 3, and the mounting beam 4 and the first vertical beam 5 can be supported. When the triangular structure installation stand 1 composed of the foundation surface is constructed, the assembling work is facilitated.

  In the structure installation stand 1 having such a configuration, when viewed as a whole, the mounting beam 4, the first vertical beam 5, and the base surface are combined in a triangular shape. The mounting beam 4, the second vertical beam 6, and the base surface are also combined in a triangular shape, and the mounting beam 4, the first vertical beam 5, and the second vertical beam 6 are also combined in a triangular shape. In this gantry 1 constructed in a triangular shape, the force acting on the mounting beam 4 is distributed and received on the mounting beam 4, the first and second vertical beams 5, 6 and the base surface. Therefore, the strength of the gantry 1 is increased. For example, the load of the solar cell module mounted on the mounting beam 4 and the wind pressure applied to the solar cell module are distributed to the mounting beam 4, the first and second vertical beams 5, 6 and the base surface. Can be received.

  In addition, the cross-sectional shape of the mounting beam 4, the first and second vertical beams 5, 6 is a hat shape, and the components of the mounting beam 4, the first and second vertical beams 5, 6 are respectively The strength is increased.

  In addition, in the present embodiment, as described above, the load applied from the mounting rail 4 to the front bracket 2 is not limited to the two bolts 14 and 16 but the tip 4 a of the mounting rail 4. Since it can also be received at the inner peripheral contact portion 2k of each side plate 2b, 2c of the front bracket 2 with which the upper edge 4d contacts, the load resistance of the connection portion between the mounting bar 4 and the front bracket 2 is increased. In addition, a load applied from the mounting beam 4 to the first vertical beam 5 or a load applied from the mounting beam 4 to the lower end portion 5a of the first vertical beam 5 via the second vertical beam 6 is also obtained. Since it is received not only by two bolts but also by the receiving portion 3i of the rear bracket 3 with which the lower side of the lower end portion 5a of the first vertical beam 5 abuts, the connection portion between the first vertical beam 5 and the rear bracket 3 The load resistance is also high.

  That is, not only the strength of the gantry 1 itself is increased due to the triangular structure of the structure installation gantry 1, but also the connection portion between the mounting beam 4 and the front bracket 2 and the first vertical beam 5 and the rear bracket. Since the strength of the connection portion between the three is high, even if the load acting on the gantry 1 is concentrated on the connection portion, it can withstand this load.

The two bolts 14 and 16 are screwed into the screw holes 2g and 2h of the side plates 2b and 2c of the front bracket 2 through the holes of the side plates 4b and 4c of the front end portion 4a, and fastened. The front end 4 a of the crosspiece 4 is connected and fixed to the front bracket 2.

  Further, as shown in FIG. 1, the upper end 5d of the first vertical beam 5 is inserted into the inside of the vicinity of the center of the hat-shaped mounting beam 4, and two bolts 26 are attached to each side wall of the mounting beam 4.
