Description

  The present invention relates to a width-variable telescopic all-weather type membrane roof, and in particular, a plurality of frames composed of two pillar members and two beam members connected to a mountain shape are connected in the spar direction by connecting members. It is related with the width-variable expansion-contraction all-weather type film body roof which comprised the tent film | membrane on the roof surface and the wall surface.

  It consists of two girder-type frames consisting of two pillars and two beams connected to a mountain shape, and is connected by connecting members in the direction of the spar. An all-weather type membrane roof called a so-called tent membrane structure is sometimes used as a temporary roof at a construction site. For example, it is installed in the upper part of the trench during trench construction and used as a rain shield or wind shield. Also, it may be used to temporarily protect equipment such as pumps and power panels installed at construction sites from wind and rain.

  An all-weather type membrane roof called a conventional tent membrane structure employs a simple structure for supporting the tent membrane. For example, a construction method is generally used in which a framework is formed by a steel pipe structure or a lattice structure in which a joint portion is a bolt joint, members are joined and assembled by bolting at a site, and a tent film is stretched on the framework.

  Patent Document 1 discloses a framework structure of a folding tent. Here, the gable part of the roof is composed of two jointed beams and a transverse beam, the roof top transverse beam is joined to the top joint part where the two jointed beams are joined, and the joint part where the jointed beam and the transverse beam are joined.

  For example, when installing an all-weather film roof in the upper part of a trench for trench construction, the conventional all-weather film roof is pre-matched to the dimensions of the span between the pillars at the installation location. The framework must be designed and manufactured. That is, it is necessary to measure the size of the frontage (span) between the column members in advance and calculate the length of the beam member and the mounting angle accordingly. For this reason, the all-weather film body roof has a problem that it must be designed each time it is used even though it has a simple structure.

  In addition, the dimension of the span between the column members at the construction site is extremely inaccurate, and when installing an all-weather membrane roof, it takes time to correct the dimensional error. there were.

  Furthermore, in the conventional all-weather membrane roof, there is a site work in which each member of the frame manufactured at the factory is brought into the construction site, and the frame is assembled by bolting etc. at the site, and the frame is further folded. There was a problem that it could not be stored or transported.

  The purpose of this application is to solve this problem and to set the connection angle between the beam material and the column material and the beam material according to the gap between the column materials at the installation location, and to change the width that can be stored and transported by folding the frame. It is to provide a type stretchable all-weather membrane roof.

In order to achieve the above-mentioned object, the width-variable stretchable and all-weather membrane roof according to the present invention is a girder connecting a plurality of frames composed of two pillar members and two beam members connected to a mountain shape. In an all-weather type membrane roof constructed by connecting in a direction and having a tent film stretched on the roof surface and wall surface, the two joints between the column and the beam and the joint between the beams are connected. Column material or beam material constitutes a hinge part that can rotate freely, and the column material at each hinge part in a state where the connection angle between the beam material and the pillar material and the beam material is set according to the frontage between the pillar materials at the installation location. One of the pillars or the beam member connected to the joint portion has a disk-like first connection plate at the end and is connected to the joint portion. The other column member or beam member has a second connection plate that is substantially the same shape as the first connection plate, and the first connection plate and the second connection plate have a substantially outer shape. The first connection plate and the second connection plate are overlapped so as to coincide with each other, and each of the first connection plate and the second connection plate has a connection through hole provided at the center of the disk and a fixing through hole at a position eccentric from the center of the disk.

By utilizing this hinge mechanism, the beam material and the connection angle between the column material and the beam material can be freely set according to the gap between the column materials at the installation location, and it is necessary to design each time it is used. Disappear. In addition, since the connection angle between the beam material and the column material and the beam material can be freely set, the framework of the all-weather type membrane body roof can be folded and stored or transported with the tent membrane attached. .

In addition, both the column members or the beam members connected to the joint portion have substantially the same disk-shaped connection plate at the end on the side to be connected, and both the connection plates have substantially the same outer shape. A simple hinge is configured by overlapping and screwing a fastener into a connection through hole provided at the center of the connection plate. And it becomes possible to freely set the connection angle between the beam member and the column member and the beam member around the hinge portion. In addition, the connection angle between the beam member and the column member and the beam member can be fixed by screwing a fastener into the fixing through hole which is a long arcuate hole provided concentrically from the center of the disk. It becomes possible.

  In addition, the width-variable telescopic all-weather membrane roof has a first fixing through hole, which is an arcuate long hole provided concentrically with the fixing through hole being further away from the center of the disk, It is preferable that the second fixing through hole is an arcuate long hole provided concentrically nearer to the center. Thereby, it is possible to more firmly fix the overlapping connection plates with a plurality of fasteners.

  Also, the width-variable stretchable all-weather type film roof has a position where the fixing through-hole is connected to the joint and one column member or beam member and the other column member or beam member are substantially straight. It is preferable to be provided so as to freely rotate from the relationship to the positional relationship of being mutually folded. Thereby, it becomes possible to fold or stretch the framework of the membrane body roof according to the present invention.

That is, the 1st column beam junction part 1 and the beam junction part 2 are shown, and description of the 2nd column beam junction part 3 is abbreviate | omitted.

  In this embodiment, the general parts of the column member 4 and the beam member 5 have a lattice structure in which two pipe members 10 made of a circular steel pipe are connected by a diagonal member 15 made of a plate material or a steel pipe. The column member 4 and the beam member 5 are connected to the first column beam joint 1 and the beam joint 2 at their ends, but in the vicinity of the first column beam joint 1 and the beam joint 2, a circular shape is formed. Two pipe members 10 made of steel pipes have a cross section connected by a web plate 11. The column member 4 and the beam member 5 are not limited to this lattice structure, and may be a section steel such as a general H-section steel having a web.

Since the first connection plate 12a and the second connection plate 12b are substantially the same shape, the first connection plate 12a and the second connection plate 12b are overlapped in FIG. 3 which is a side view, but are overlapped as shown in the AA cross section of FIG. The first connection plate 12 a and the second connection plate 12 b are integrated with the web plate 11 of the column material 4 or the beam material 5 connected to the first column beam connection portion 1 and the beam connection portion 2. That is, the first connection plate 12 a and the second connection plate 12 b are made of a plate material that is continuous with the web plate 11 of the column material 4 or the beam material 5. Moreover, the processing agent 16 which prevents the board slip | sliding is given to the board surface which the 1st connection board 12a and the 2nd connection board 12b which are piled up mutually oppose. In this embodiment, the treatment agent 16 for preventing the slip is shot blasting and hot dip galvanizing, but is not limited to this treatment.

  The two column beam joints 1 and 3 formed by the column material 4 and the beam material 5 and the beam joint portion 2 between the beam materials 5 include three hinge portions to which the column material 4 or the beam material 5 to be connected is rotatable. Since it comprises, the connection angle of pillar material 4 and beam material 5 and beam material 5 can be set up according to the frontage (span) of the foundation of an installation place.

  In other words, the first connection plate 12a and the second connection plate 12b are overlapped so that the outer shapes thereof substantially coincide. And the 1st connection board 12a and the 2nd connection board 12b have the through-hole 7 for connection provided in the center of a disk, and the through-holes 8 and 9 for fixation in the position eccentric from the center of a disk. The first connection plate 12a and the second connection plate are formed by screwing the connection fastening bolts 13 serving as fasteners into the opposing connection through holes 7 of the first connection plate 12a and the second connection plate 12b that are overlapped. 12b is rotatably connected. Further, the fixing fastening bolts 14a and 14b, which are fasteners, are screwed into the opposing fixing through holes 8 and 9 of the first connecting plate 12a and the second connecting plate 12b that are overlapped, thereby connecting the column members. The rotation of 4 or beam 5 is fixed. That is, the center point of the connecting through hole 7 becomes the center of rotation of the hinge, and the fixing fastening bolts 14a and 14b are screwed into the fixing through holes 8 and 9 that are eccentric from the center of the disk, thereby rotating the hinge. Is prevented and the first connection plate 12a and the second connection plate 12b are fixed to each other.

  In the present embodiment, the fixing through-holes 8 and 9 are concentric with the first fixing through-hole 8 which is an arcuate long hole provided concentrically away from the center of the disk and closer to the center of the disk. And a second fixing through-hole 9 which is an arcuate long hole provided in. Then, the connecting fastening bolt 13 is screwed into the connecting through hole 7, the fixing fastening bolt 14 a is screwed into the first fixing through hole 8, and the fixing fastening bolt 14 a is fastened to the second fixing through hole 9. The bolt 14b is screwed. Thereby, the overlapped first connection plate 12a and second connection plate 12b are firmly fixed by the plurality of fixing fastening bolts 14a and 14b.

  In FIG. 4, the 1st connection board 12a of the column material 4 and the 2nd connection board 12b of the beam material 5 which are mutually piled up in the 1st column beam junction part 1 are shown side by side. The configuration of the connecting plate 12 is the same in the beam joint 2 and the second column beam joint 3.

  Four quadrants divided at an angle α (approximately 90 degrees) by an axis passing through the center and an axis orthogonal to the axis are set in the first connection plate 12a and the second connection plate 12b. The first fixing through-hole 8 provided in the first connection plate 12a and the first fixing through-hole 8 provided in the second connection plate 12b are provided in quadrants shifted from each other by approximately 90 degrees. Further, eight quadrants divided by an angle β (approximately 45 degrees) are set in the first connection plate 12a and the second connection plate 12b. Then, the second fixing through hole 9 provided in the first connection plate 12a and the second fixing through hole 9 provided in the second connection plate 12b are provided in quadrants shifted from each other by approximately 90 degrees. The positions of the first fixing through holes 8 and the second fixing through holes 9 of the first connecting plate 12a and the second connecting plate 12b in FIG. 4 are opposite to each other in the first connecting plate 12a and the second connecting plate 12b.

The column member 4 and the beam member 5 or the beam members 5 that are overlapped with each other by the first fixing through hole 8 and the second fixing through hole 9 provided in such a configuration are shown in FIG. As shown in FIG. 4, a positional relationship that is substantially linear can be obtained. In addition, as shown in FIG. 5B, the positional relationship of being mutually folded can be taken. That is, it can be rotated freely continuously from the positional relationship of FIG. 5A to the positional relationship of FIG.

  That is, the column member 4 and the beam member 5 or the beam member 5 connected to each other can be relatively rotated by approximately 180 degrees. This is because when the fixing fastening bolt 14a is fixed to one end of the first fixing through-hole 8 of the first connecting plate 12a, the fixing fastening bolt 14a becomes the first fixing through-hole of the second connecting plate 12b. When the fixing fastening bolt 14a is fixed to the other end of the first fixing through hole 8 of the second connection plate 12b, the fixing fastening bolt 14a is This is explained by the fact that the first connecting plate 12a can be positioned by rotating approximately 90 degrees with respect to the first fixing through-hole 8. That is, the first connection plate 12a and the second connection plate 12b have a mechanism that can rotate 90 degrees with respect to each other and can rotate over a range of 180 degrees. This mechanism is the same for the fixing fastening bolt 14b.

  By this mechanism, the width-variable telescopic all-weather membrane roof 20 can be extended and folded in the vertical direction as shown in FIG. 5 (c), and in the lateral direction as shown in FIG. 5 (d). It can also be crushed and folded. As a result, the framework can be folded and stored or transported.
