[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prefabricated roof used as a roof for rain and awning at a bus stop, a taxi stand, a garage space, a passageway between buildings such as a corridor, and an approach between a gate and an entrance.

[0002]

[Prior art]

 Assembled roofs that have been conventionally used for roofs of bus stops and the like have structures shown in FIGS. 7 to 9. This conventional assembled roof mainly consists of a plurality of columns 1, girders 2, beams 3, purlins 4 and panel members 5. Joint metal fittings 6a and 6b were used to connect the support 1 and the girder 2, and screw fittings were fixed to both ends of the beam receiving metal fittings 7 and 7 fixed to the girder 2 to connect the girder 2 and the beam 3. The U-shaped connecting fittings 8 and 8 are used.

This conventional structure is generally assembled in the following procedure. That is, (1) Place the girder 2 on the upper end of the strut 1 via the strut cap 9, and sandwich the side surface of the girder 2 with joint fittings 6a and 6b, and pass the stud bolt 10 through the strut 1 and the joint fittings 6a and 6b. Tighten 11 and connect the strut 1 and the girder 2. (2) As shown by the arrow A in FIG. 7, in the portion to be installed in a tilted state, the fitting angle of the joint metal fitting 6a (also the joint metal fitting 6b (not shown)) should be adjusted according to the inclination. Tilt. (3) The beam 3 is bridged between the beam receiving metal fittings 7 and 7 fixedly mounted on the opposing girders 2 and screwed. Specifically, the connecting metal fittings 8, 8 at both ends of the beam 3 are clamped by a circular thin plate-shaped beam receiving metal fitting 7 and screwed from both sides. (4) The purlin 4 is screwed at the center between the beams 3 and 3. (5) A panel receiving member 12 having an inverted L-shaped cross section is screwed to the connecting fitting 8 so as to cover the space between the beam receiving fittings 7, 7. (6) The panel material 5 serving as a roof material is screwed to the opening portion X surrounded by the pair of beams 3, 3, the purlin 4, and the beam receiving metal fitting 7 one by one from the upper side. Reference numeral 13 in FIG. 7 is a cover material, which is mounted on the beam 3 and the purlin 4 to sandwich the edge of the panel material 5.

[Problems to be solved by the device]

 In the conventional roof as described above, the position of the beam receiving metal fittings 7 cannot be changed, so that the dimension between the beam receiving metal fittings 7, 7 and the length of the beam 3 including the connecting metal fittings 8, 8 are almost exactly the same. It is difficult to stretch the beam 3 unless the column 1 is erected so that the beam 2 is attached to the column 1. For the same reason, if the length of the beam 3 is slightly different, the beam 3 may not be attached. Further, the beam 3 may be cut down in order to adjust the frontage size at the site, but in this case, it is necessary to cut the both ends of the beam 3 accurately along the diameter passing through the center of curvature. That is, since the beam receiving metal fitting 7 is fixed to the girder 2, if the angle of the end surface of the beam 3 changes due to cutting, the connection between the beam receiving metal fitting 7 and the connecting metal fitting 8 becomes poor and the connection becomes impossible. This is because the condition also occurs. However, it is difficult to perform such a truncation that requires high precision on site, and it has become a very difficult task for site workers.

Further, in the installation on a sloped ground, the inclination angles of the facing girders 2 and 2 and the inclination angles of the joint fittings 6a and 6b with respect to the support column 1 must be properly matched. For this reason, the girder 2 is placed on the column cap 9 and the joint fittings 6a and 6b are loosely bolted to adjust the inclination angles of the girders 2 and 2 and the joint fittings 6a and 6b are also tilted to correspond to each other. It is necessary to adjust the tightening of the screws so that they are even. In other words, the skill of the worker is required to a considerable extent, and thus the troublesome work is required.

The present invention has been made in view of the above problems of the prior art, and can easily change the distance between the column and the girder, change the length of the beam, and change the state of engagement between the beam and the girder due to truncation of the beam. The purpose is to provide a prefabricated roof that can be installed and can be easily installed in a tilted state.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the assembled roof according to the present invention is to be attached to a girder stretched over columns or other structures, in which brackets for connecting pins are attached to both ends of the beam to attach the beam on the girder. Attach the bracket holder to the corresponding position so that the position can be adjusted in the beam straddling direction, and pivotally support the bracket on the bracket holder with a pin so that it can swing vertically along the length of the beam. It is configured to be pin-coupled.

In the assembled roof according to the present invention, a connecting device for pin connection is arranged between the lower surface of the girder and the upper ends of the columns, and the connecting device is fixed to a column-corresponding position on the lower surface of the girder and protrudes downward. And a second projecting piece member that is fixed to the upper end surface of the column and projects upward.The first and second projecting piece members are combined, and the swinging direction is along the longitudinal direction of the girder. The pins can be connected so that they are vertically oriented.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded partial perspective view showing an enlarged assembly structure of an assembled roof according to an embodiment of the present invention, FIG. 2 is a partial perspective view of the same assembled state, and FIG. 3 is an assembly according to one embodiment of the present invention. FIG. 4 is a side view showing a state in which the roof is erected on a slope, and FIG. 4 is an enlarged sectional view taken along the line 4-4 in FIG. 5 is an exploded perspective view showing the bracket and the bracket receiver shown in FIG. 1 in an extracted manner, and FIG. 6 is an enlarged side view of a portion indicated by an arrow B in FIG.

The assembled roof shown in the figure is constructed by spanning a roof unit 20 on a girder 22 attached to the upper ends of columns 21.

First, the connection structure of the support column 21 and the girder 22 will be described. The cross-sectional shape of the girder 22 is such that a rectangular portion 24 for fixing a connecting fitting 23 for attaching the roof unit 20 to the upper flat surface 22a is formed on the inside and a groove portion 25 serving as a rain gutter is formed on the outside. It is attached to the upper end of the column 21 via 26. The connecting device 26 includes an upper substrate 27 that is screwed to the lower surface of the girder 22, an upper connecting plate 28 that projects from the lower surface of the upper substrate 27, a lower substrate 29 that is screwed to the upper end surface of the column 21, and a lower substrate 29. The base plate 29 is composed of a pair of lower connecting plates 30 and 30 protruding upward with a predetermined gap. The upper connecting plate 28 and the lower connecting plate 30 are provided with bolt holes 28a and 30a, respectively, and pin connection can be made by inserting the connecting bolt 31 with the upper substrate 28 sandwiched between the lower base plates 30 and 30. It is like this.

That is, since the beam 22 is attached to the two columns 21 by the connecting device 26, a so-called parallel link is formed. Therefore, if the upper connecting plate 28 and the lower connecting plate 30 are combined and the cap nut 32 is loosely fitted to the connecting bolt 31, the girder 22 is moved in the longitudinal direction thereof to form a line connecting the upper ends of the columns 21, 21. On the other hand, the position can be changed while always keeping parallel, and the position can be fixed by tightly tightening the cap nut 32.

Next, the roof unit 20 will be described. The roof body unit 20 mainly includes a beam 33, a purlin 34, a bracket 35, a panel receiving member 36, and a panel material 37. Each of these components is made of extruded aluminum or shaped steel.

The beam 33 has a generally rectangular cross-sectional shape (see FIG. 6), and has an arc shape with a relatively large radius of curvature to form a flat, semi-cylindrical roof-shaped arch (see FIG. 4). . The beam 33 has a protrusion 39 formed at the center thereof to be combined with the pressing member 38. Further, the purlin 34 has a substantially rectangular cross-sectional shape similar to the beam 33, and has a protrusion 41 which is combined with the pressing member 40 and has a slightly recessed central portion. These projections 39 and 41 allow a gap to be formed along the longitudinal direction of the side surface when the pressing members 38 and 40 are combined with the beam 33 and the purlin 34, so that the edge of the panel member 37 is relatively loosely sandwiched. It can be held.

The bracket 35 includes a base portion 42 having a hollow interior, an insertion end portion 43 protruding from the base portion 42 toward the purlin 34, and a drain attachment portion having an inverted L-shaped cross section formed at the rear end of the base portion 42. And 44. The base portion 42 is provided with a shaft hole 45 on its side surface for pin-connecting to the connecting fitting 23 on the girder 22, and a step portion 46a for screwing a receiving plate 46 for attaching the panel receiving member 36 to the insertion end portion 43 side. Is formed. The insertion end 43 has a rectangular parallelepiped shape with a slight taper at the tip, and can be inserted into the beam 33 and screwed. Further, a water drain 47 can be screwed to the water drain mounting portion 44.

The connecting fitting 23 is formed by arranging a pair of connecting plates 49, 49 on a substrate 48 with a space therebetween. The distance between the connecting plates 49, 49 is such that they can be inserted into the base portion 42 of the bracket 35, and a pin hole 50 is provided at a position corresponding to the shaft hole 45 of the base portion 42 of the bracket 35. Further, the board 48 is configured such that a screw 52 is screwed into the upper flat surface 22a of the rectangular portion 24 of the girder 22 from a pair of long holes 51 and fixed along the extending direction of the beam 33 within the range of the long hole 51. The fixed position is variable.

The panel receiving member 36 has a substantially inverted L-shaped cross section, and has a groove portion 53 at one edge portion and a panel insertion portion 54 at the other edge portion. The groove portion 53 is for connecting the panel receiving member 36 to the side surface side of the bracket 35 by receiving the tip of the receiving plate 46 and connecting it with a screw. Further, the panel insertion portion 54 forms a groove having a U-shaped cross section, and can receive and hold the lower end edge of the panel material 37. The bracket 35 side of the panel insertion portion 54 is cut out in an appropriate size so that rain or the like flowing down the surface of the panel material 37 flows into the groove portion 25 of the girder 22 from there.

As the panel material 37, for example, a synthetic resin flat plate having a light-transmitting property is used. Of course, the panel material 37 is a roof material used for an assembled roof of this kind. Any material can be adopted as long as it can be sandwiched between the materials 38 and 40 and the lower edge can be inserted into the panel insertion portion 54 of the panel receiving member 36.

Next, a procedure for assembling the assembled roof according to this embodiment will be described. (1) A girder 22 is attached to the upper ends of a plurality of columns 21 standing upright at a predetermined position on a sloping ground via a coupling device 26, and the girder 22 is attached to the line connecting the upper ends of the columns 21, 21 as described above. Are moved in parallel, and the height positions of the left and right girders 22, 22 are aligned. It is to be noted that the connection fitting 23 is temporarily fixed to the girder 22 in advance at the connection position of the beam 33 with the screw 52. (2) On the other hand, the roof unit 20 is assembled as follows as a work separate from the stand upright and the girder 22 installation. Unlike the work of the conventional example, the work of assembling the roof unit 20 is performed on the ground or a workbench. (A) Insert the insertion ends 43 of the brackets 35 into both ends of all the beams 33, and screw them from the upper surface side of the beams 33. (B) A purlin 34 is connected to the central portion of the beam 33 to form a frame structure as the roof unit 20. Although the connection structure of the beam 33 and the purlin 34 is not shown, various conventionally known connection methods may be adopted. (C) The panel receiving member 36 is positioned with respect to the bracket 35 so that the end of the receiving plate 46 screwed to the stepped portion 46a of the bracket 35 enters the groove 53, and the receiving plate 46 and the panel receiving member 36 are positioned. The member 36 is screwed and fixed. Although illustration is omitted, in this state, an opening portion similar to the opening portion X in the conventional example is formed by the pair of beams 33, 33, the purlin 34, and the panel receiving member 36. The portion indicated by the arrow X1 in FIG. 3 corresponds to the opening portion, but in FIG. 3, the panel member 37 is of course already attached. (D) The lower edge of the panel material 37 is inserted into the panel insertion portion 54 of the panel receiving member 36, and the side edge is placed on the beam 33. The upper edge of the panel material 37 is placed on the purlin 34. As a result, the opening portion X1 is closed, and the pressing members 38 and 40 are placed on the side edge and the upper edge of the panel material 37 and fixed to the beam 33 and the purlin 34 to complete the unitization. The side edge and the upper edge of the panel member 37 are sandwiched between the beam 33, the purlin 34 and the pressing members 38, 40 so as not to get over the projections 39, 41 of the beam 33, the purlin 34, as described above. Of course, (3) The roof body unit 20 assembled as described above is lifted by a plurality of workers or by using a unic car or the like and placed on the girder 22, and the fitting fitting on the girder 22 is placed in the base 42 of the bracket 35. The connecting plate 49 of 23 is fitted, and the bolt 54 is inserted from the shaft hole 45 of the bracket 35 to be pin-connected. (4) The installation interval of the columns 21 and the installation interval of the girders 22 are deviated from the design position, the length of the beam 33 does not conform to the design dimension, and further, the beam 33 is truncated so that the bracket 35 and the connecting bracket 23 If there is any deviation in the connection, the connection hole 23 is moved in the straddling direction of the beam 33 using the long hole 51 to finely adjust the connection position. At this time, the angle of the bracket 35 is different from the expected angle, but as described above, since the bracket 35 and the connecting fitting 23 are pin connections that can swing in the vertical direction, the bracket 35 is attached to the connecting fitting 23. Once installed, the change in angle is not a problem during installation.

The drainer 47 may be attached to the drainer mounting portion 44 of the bracket 35 in the above (2) (c) or (d), or after the above (4). Further, since the roof body unit 20 may be assembled on-site, or may be pre-assembled in a factory or the like and then transported to the site, the steps (1) and (2) above are not required. It doesn't mean that either has to be done first.

[0021]

[Effect of device]

 As described above, in the assembled roof according to claim 1, bracket brackets on the girder to be combined with the brackets attached to both ends of the beam are attached so that the position of the bracket can be adjusted in the straddling direction of the beam. Since the pins are connected, the spacing between the columns and girders and the length of the beams are not as designed, or even if the beams are cut down, the girders and beams can be connected easily and accurately. This has the effect of reducing the burden of on-site work.

In the assembled roof according to the second aspect, since the girder is connected to the upper end of the pillar through the connecting device for pin connection, in addition to the common effects described above, the girder is more likely to be installed when installed in an inclined state. This has the effect that the angle of the upper roof component can be easily changed according to the inclination.
