JP 2009-167754 A

  The conventional installation fixture described above has a risk of rainwater entering from the large work hole 22 formed on the lateral outer side of the base support member 5 and the second insertion hole 24 formed on the upper surface of the installation support member. In addition, there is a risk of rainwater entering from the bolt insertion part 17 into the ground support member 5, and when rainwater enters the ground support member 5, the water enters the ground through the fixing part 12, and the interior of the building There was a risk of leaking water into the water, and we had to consider a waterproof structure that tightly seals.

  Accordingly, an object of the present invention is to provide an installation fixture that solves the above-described problems and easily prevents rainwater from entering the ground support member.

  The first characteristic configuration of the present invention includes a bottomed cylindrical base-side support member that forms an opening in the upper portion, a flange portion that extends laterally outside, and a fixing portion for mounting base on the bottom portion. A first vertical wall extending in the vertical direction by providing a lid-like installation support member that covers the opening and the flange portion from above, and a first peripheral wall portion that hangs downward on the outer edge of the flange portion. A second peripheral wall portion that surrounds the outside of the first peripheral wall portion is connected to the outer edge portion of the installation object support member with the flange portion covered from above by the installation object support member. A second vertical wall portion is formed in the second peripheral wall portion along the vertical direction, and the first vertical wall portion and the second vertical wall portion are provided with insertion holes for both support member connecting bolts, and are connected to each other. A flexible connecting part is formed, and the head of the connecting bolt for the installation object can be freely engaged. An insertion portion is provided on the installation support member, and a bowl-shaped rainwater guidance guide portion is integrally provided on the lower surface of the bolt insertion portion, and a drain side end of the rainwater guidance guide portion is formed on the second peripheral wall portion. The rainwater guiding guide portion receives the rainwater entering through the bolt insertion portion and discharges it to the laterally outward side of the installation object support member.

According to the first characteristic configuration of the present invention, after the work for fixing the fixing portion to the mounting base via the anchor bolt or the like is performed through the opening on the upper side, the opening and the flange are fixed. The opening is closed by covering it as a lid with the installation object support member.
When closing the opening by the installation object support member, the first peripheral wall part hanging downward is continuously provided on the outer edge of the flange part, and the flange part is covered with the installation object support member from above, A second peripheral wall portion that surrounds the outside of the first peripheral wall portion is connected to an outer edge portion of the installation object support member, and a connecting portion that is connectable to the first peripheral wall portion and the second peripheral wall portion is provided. Accordingly, the installation object support member and the base side support member can be connected to each other outside the opening and at a position lower than the outer edge of the flange portion. There is no intrusion.
Then, in order to fix the installation object such as equipment to the installation object support member, the installation bolt is locked to the installation object support member through the connection bolt by locking the connection bolt through the bolt insertion portion. Easy to fix.
In addition, a rainwater guiding guide portion is provided below the bolt insertion portion to receive rainwater entering through the bolt insertion portion and discharge the rainwater laterally outside the installation support member. Without intruding into the member, it is reliably discharged laterally outward from the installation support member.
Eventually, it became possible to eliminate the cause of water leakage into the building.

  Rainwater which tries to invade through the bolts connected at the connecting part by connecting the installation object supporting member and the base side supporting member by the connecting parts provided on the first vertical wall part and the second vertical wall part. Can reliably flow downward along the first and second vertical wall portions outside the opening of the base-side support member, and more reliably prevent water from entering the base-side support member. It became so.

  According to a second feature of the present invention, a bottomed cylindrical base support member that forms an opening at the top is provided, and a lid-like installation support member that covers the opening from above is provided. A flange portion extending in the circumferential direction is provided at a position lower than the opening in the first vertical wall portion on the lateral outer side of the support member, and a fixing portion to the mounting base is provided at the bottom of the base side support member, In a state where the opening and the first vertical wall are covered from above with the installation object support member, a connecting part that can be connected to the flange part is connected to the second vertical wall part in the outer peripheral part of the installation object support member. A bolt insertion portion that is provided on the second horizontal wall portion to be installed, and capable of engaging with a head portion of a connecting bolt to the installation object, is provided on the installation object support member; Provided integrally with the rainwater guide section The drainage side end is connected to a drainage port formed in the second vertical wall portion of the installation support member, and receives the rainwater entering through the bolt insertion portion by the rainwater guidance guide portion and supports the installation It exists in the place comprised so that it may discharge | emit to the lateral outward of a member.

  According to the second characteristic configuration of the present invention, by connecting the connecting portion of the installation object supporting member connected to the base side supporting member with the flange portion extending to a position lower than the opening portion, The rainwater that enters does not enter the opening, and the rainwater that enters through the bolt insertion portion is discharged laterally outward from the installation support member by the rainwater guiding guide portion. Accordingly, it is possible to prevent rainwater from entering the ground side support member and eliminate the cause of water leakage into the building.

  According to a third characteristic configuration of the present invention, the bolt insertion portion is formed in a shape in which the connecting bolt can be mounted and adjusted.

  According to the third characteristic configuration of the present invention, the bolt insertion portion is formed in a shape that allows the mounting position of the connecting bolt to be adjusted, so that the relative fixing position of the installation object with respect to the installation object support member can be determined. Can be adjusted.

  According to a fourth characteristic configuration of the present invention, the bolt insertion portion is formed from a long hole, and the longitudinal direction of the long hole is arranged along the position adjustment direction of the connecting bolt. On the lower side, a detent portion for the connecting bolt is provided.

  According to the fourth characteristic configuration of the present invention, the installation bolt is adjusted by adjusting the bolt fixing position along the longitudinal direction of the long hole by inserting the connecting bolt through the bolt insertion hole formed from the long hole. The relative fixing position of the installation object 3 with respect to the bolt can be adjusted, and in addition, the connecting bolt is prevented from being rotated by the rotation preventing part below the bolt insertion part, so that the nut is tightened from above the installation object supporting member. You can easily fix the installed object.
