  In the above-described prior art, when installing a support on a goby type folded plate roof, the support is installed on the goze part via a fixing bracket, so that it is not necessary to make a hole for installing the support on the folded plate roof. . However, existing folded plate roofs include not only the goby type but also the bolt type. Since the bolt type folded plate roof does not have a goby portion, it is difficult to attach a fixing bracket. Therefore, it is necessary to make a hole in the bolt-type folded plate roof and fix the lower end of the leg of the support column to the roof surface with bolts and nuts. As a result, water leakage may occur through the formed hole. Moreover, in order to perform work without making a hole in the bolt-type folded-plate roof, an external scaffold must be installed, and the work period becomes longer and the work cost increases.

  The present invention has been made in view of the background described above, and peaks and valleys are alternately arranged, and a tripod-like column is provided without making a hole in a metal roof provided with bolts protruding from the peaks. It is intended to provide a column base that can be installed.

In one embodiment of the present invention, peaks and valleys are alternately arranged, and used to attach a tripod-like column having three legs to a metal roof having bolts protruding from the peaks. A pedestal pedestal,
It is configured to be able to straddle at least one or more of the mountain parts, one or more insertion holes for inserting the bolts included in the mountain parts that are straddled, and one of the pillars provided A base portion comprising a first fastening member capable of fastening the lower end of the leg, and
It is comprised so that it can fix to the said base part along the working width direction of the said metal roof, and it equips both ends with a pair of 2nd fastening member which can respectively fasten the lower end part of each remaining leg with which the said support | pillar is provided. An arm,
The pedestal has a pedestal.

  Using the above-mentioned support pedestal, for example, a tripod-shaped support can be installed on a metal roof provided with a bolt protruding from a mountain as follows. First, an arm part is fixed to a base part along the working width direction of a metal roof. Next, the base portion is disposed so as to straddle at least one or more mountain portions, and the bolts included in the straddled mountain portions are inserted into the insertion holes and fixed with nuts. Next, the lower end of one leg included in the support is fixed to the base by the first fastening member, and the lower end of each remaining leg included in the support is fixed to the arm by the pair of second fastening members. To do.

  According to the support pedestal, it is possible to install a tripod-like support without using a hole by using a bolt of a metal roof provided with a bolt protruding from a mountain portion. According to the support pedestal, since it is not necessary to make a hole in the metal roof, water leakage hardly occurs. According to the above-mentioned support pedestal, it is possible to configure the safety equipment by installing the support without installing an external scaffold, and it is easy to remove the support, so that the work period is shortened and the work cost is suppressed. Can be planned. The above-mentioned support base can be made to correspond to various metal roofs such as a bolt-type folded plate roof and a roof tile roof to which a bolt protruding from a mountain portion with a metal fitting is attached by changing the base portion. Moreover, according to the said support | pillar base, when the impact load is loaded to the support | pillar, compared with the case where the leg body of a support | pillar is directly fixed to the metal roof, it is easy to disperse | distribute the force by an impact load. Therefore, according to the said support | pillar base, it is easy to suppress the damage of the metal roof by an impact load.

It is a top view of the support | pillar base of Example 1. FIG. It is the support | pillar base of Example 1 seen from the A arrow direction shown by FIG. It is the support | pillar base of Example 1 seen from the B arrow direction shown by FIG. It is the support | pillar base of Example 1 seen from the C arrow direction shown by FIG. 1, and one part was shown by the cross section. It is explanatory drawing which shows the state by which the support | pillar base of Example 1 was folded. It is explanatory drawing which shows the closed leg state of the support | pillar used for the support | pillar base of Example 1. FIG.

  The metal roof to which the support pedestal is applied includes a bolt protruding from the mountain portion. The bolt that protrudes from the mountain portion may be a bolt that is used when the metal roof is rolled, or may be a bolt that is attached to the mountain portion of the metal roof via a metal fitting. Examples of the metal roof include a bolt-type folded plate roof in which a tight frame bolt protrudes from the mountain portion as the above-mentioned bolt, and a roof tile roof in which a bolt protruding using a metal fitting is attached to the mountain portion.

  In the support pedestal, the arm portion may be configured to be fixable to the base portion along the longitudinal direction of the base portion.

  According to this structure, an arm part can be fixed to a base part along the longitudinal direction of a base part other than the working width direction (short direction of a base part) of a metal roof. Therefore, in the state where no support is installed, by fixing the arm part to the base part along the longitudinal direction of the base part, the support pedestal can be transported without projecting both ends of the arm part from the base part. Is possible. Therefore, a column base that can be transported in a compact state is obtained. On the other hand, when installing the support column, it is possible to install the tripod-shaped support column by fixing the arm unit to the base unit along the working width direction of the metal roof. Therefore, according to said structure, the support | pillar base excellent in the conveyance property and the installation property of a support | pillar is obtained.

  In the column base, the base portion specifically includes a flat plate portion including an insertion hole and a first fastening member, and a first side surface that extends from both side edges of the flat plate portion and covers the first side surface of the peak portion. It can be set as the structure which has a 2nd side part which covers the 2nd side surface of a part and a peak part.

  According to this configuration, the first side surface portion covers the first side surface of the mountain portion on one end side in the working width direction of the metal roof among the one or more mountain portions straddled by the base portion. Is placed. Moreover, a 2nd side part is arrange | positioned so that the 2nd side surface of the peak part in the other end side of the working width direction of a metal roof among one or more peak parts straddled by the base part may be covered. . For this reason, the first side surface portion and the second side surface portion can easily suppress the positional deviation in the working width direction of the metal roof, and a column base that can easily insert the bolt protruding from the mountain portion into the insertion hole is obtained. Further, after the support is installed, a support pedestal that can easily suppress the backlash of the support pedestal is obtained. In addition, the stability of the column base can be improved.

  The said support | pillar base can be set as the structure by which the raising member for adjusting the height of a base part is provided in the surface at the side of the metal roof in a base part.

  According to this configuration, it is possible to adjust the height of the nut screwed into the bolt. Therefore, it is possible to obtain a column base in which the base portion can be easily arranged in parallel to the roof surface of the metal roof.

  When the arm part is fixed to the base part along the working width direction of the metal roof, each of the support bases has a configuration in which insertion holes are present in the base part parts on both sides sandwiching the arm part, respectively. can do.

  According to this configuration, for example, when installing a column near the eaves, the eaves are inserted into the insertion hole in the base part on the eaves side as viewed from the arm part fixed along the working width direction of the metal roof. The base part can be fixed by inserting the bolt on the side. In addition, for example, when setting a column near the keraba, the keraba side is inserted into the insertion hole in the base portion opposite to the eaves side when viewed from the arm portion fixed along the working width direction of the metal roof. The base part can be fixed by inserting the bolt. Therefore, according to this configuration, it is possible to select a bolt insertion point when installing a column near the eaves and when installing a column near the keraba, and it is possible to freely attach the column base to the metal roof. The degree is improved. In addition, according to this configuration, in particular, when a column is installed in the vicinity of the keraba, it is easy to select a bolt insertion place where the column base is more stable, which can contribute to an improvement in the mounting stability of the column base.

  In the support pedestal, the arm portion may include a fixed plate portion fixed to the base portion and a reinforcing rib provided on at least one side edge of the fixed plate portion.

  According to this configuration, the rigidity of the arm portion is improved by the reinforcing rib. Therefore, even when a load is transmitted from the leg body of the support column to the arm portion, the leg body can be reliably supported.

  In the above-mentioned column base, the column specifically has three legs of the same shape and the same dimensions, and a connecting member that connects the upper ends of each leg, and loosens the connecting member. Thus, each leg can be relatively rotated about the connecting member as an axis, and each leg can be made non-rotatable by tightening the connecting member.

  According to this configuration, by tightening the connecting member, it is possible to connect the plurality of legs in a non-rotatable manner with the lower ends of the legs spaced apart. Therefore, the support can be in an open leg state in which each leg is opened in a tripod shape. Further, by loosening the connecting member, the legs having the same shape and the same dimensions can be rotated relative to each other so that the legs can overlap each other. Therefore, the support column can be folded into a closed leg state in which each leg is closed. Therefore, according to this configuration, it is possible to assemble the support so as to change from the closed leg state to the open leg state in a relatively short time, and to install the support post on the metal roof via the support base. Moreover, according to this structure, it becomes possible to fold the support | pillar so that it may become a closed leg state from an open state in a comparatively short time, and to remove from a metal roof with a support | pillar base.

  In addition, each structure mentioned above can be arbitrarily combined as needed, in order to acquire each effect etc. which were mentioned above.

  Hereinafter, the column base of the embodiment will be described with reference to the drawings. In addition, about the same member, it demonstrates using the same code | symbol.

  The arm portion 3 is configured to be fixed to the base portion 2 along the working width direction of the metal roof 9. Specifically, in this example, when the arm portion 3 is arranged along the working width direction of the metal roof 9, a plurality of arm portion side attachments are provided in the region of the arm portion 3 that overlaps the flat plate portion 22 of the base portion 2. A hole 33 is formed. A plurality of base portion side mounting holes 23 are formed in the flat plate portion 22 of the base portion 2 corresponding to the arm portion side mounting holes 33. In this example, two arm part side mounting holes 33 and two base part side mounting holes 23 are formed. Therefore, in this example, the arm part 3 is arranged along the working width direction of the metal roof 9, and the arm part side mounting hole 33 and the base part side mounting hole 23 are made to coincide with each other. The arm portion 3 can be fixed to the base portion 2 along the working width direction of the metal roof 9 by inserting bolts into the holes and fixing them with nuts.

  In this example, when the arm part 3 is fixed to the base part 2 along the working width direction of the metal roof 9 (short direction of the base part 2), the parts of the base part 2 on both sides sandwiching the arm part 3 The insertion holes 20 are respectively present. Here, one or more (two in this example) insertion holes 20 exist in the base part 2 on the eaves side as viewed from the arm part 3 fixed along the working width direction of the metal roof 9. Yes. Specifically, two insertion holes 20 are arranged along the width direction in the portion of the base portion 2 on the eaves side as viewed from the arm portion 3. These insertion holes 20 are mainly used when a support is installed in the vicinity of the eaves. On the other hand, one or more insertion holes 20 (two in this example) are present in the portion of the base 2 opposite to the eaves side as viewed from the arm 3 fixed along the working width direction of the metal roof 9. doing. Specifically, two insertion holes 20 are provided in the portion of the base portion 2 on the side opposite to the eaves side as viewed from the arm portion 3, along the substantially central portion in the longitudinal direction of the base portion 2 and along the working width direction. Are arranged. These insertion holes 20 are mainly used when a support column is installed at a position near the keraba. Each insertion hole 20 is a long hole that is long in the working width direction so that a positional shift of a bolt 93 such as an existing tight frame bolt can be allowed to some extent.

  In this example, the arm portion 3 is further configured to be fixed to the base portion 2 along the longitudinal direction of the base portion 2. Specifically, the arm part 3 is arranged along the longitudinal direction of the base part 2, the arm part side mounting hole 33 and the base part side mounting hole 23 are aligned, and a bolt is attached to the formed mounting hole. By inserting and fixing with a nut, the arm part 3 can be fixed to the base part 2 along the longitudinal direction of the base part 2. Therefore, if the nut is loosened, the arm portion 3 can be rotated around the bolt inserted into the mounting hole. In the state where the arm portion 3 is fixed to the base portion 2 along the longitudinal direction of the base portion 2, bolts are previously provided in the remaining base portion side mounting holes 23 that are not used for fixing the arm portion 3.
