BACKGROUND OF THE INVENTION
The present invention relates to a concrete buried type facility in which concrete buried type equipment such as a drain main body and a lid receiving frame of a roof drain buried in a concrete surface can be easily separated from concrete at the time of dismantling of a building. The present invention relates to a method for fixing equipment and a fixing device for concrete buried equipment.
[0002]
[Prior art]
FIG. 18 shows a construction state of the driving type roof drain a as an example of a conventional concrete buried type equipment. The driving type roof drain a includes a plurality of anchors e bent in a substantially L shape on the back surface of a drain body b of a drain body b composed of a drain tray c and a drain pipe portion d. When constructing the driving type roof drain a, concrete is placed around the drain receiving tray c in a state where the drain receiving tray c is temporarily fixed on the concrete mold by a temporary fixing device (not shown). Thereby, the anchor e is embedded in the hardened concrete p, and the drain main body b is fixed to the concrete p through the fixing action of the anchor e.
[0003]
[Problems to be solved by the invention]
By the way, when the building is demolished at the time of removal, rebuilding, or renovation of a building in which a concrete buried type equipment such as a conventional driving roof drain a is installed, the drain main body b becomes as described above. Since it is firmly fixed to the concrete p by the substantially L-shaped anchor e, there is a problem in that the drain body b cannot be easily separated from the concrete p and waste cannot be separated. That is, there has been a problem that it cannot cope with the recycling of waste, which is raised as a problem in the building demolition waste recycling program under the Construction Recycling Law.
[0004]
The object of the present invention is to eliminate such problems.
[0005]
[Means for Solving the Problems]
The present invention relates to a concrete buried type equipment that is buried in the concrete surface and is fixed to the concrete by an anchor provided on the lower surface. The concrete surface is provided with a loading recess having substantially the same shape as the concrete buried type equipment. An anchor member having a female screw hole into which a fixing screw can be screwed is embedded in the inner bottom surface of the insertion recess, and the fixing screw inserted from the surface side into a concrete buried type equipment is the anchor member. The concrete buried type equipment is fixed in such a manner that the concrete buried type equipment inserted into the insertion recess is detachably fixed by being screwed into the female screw hole.
[0006]
Here, the above-mentioned insertion recess can be formed by using a punching die having substantially the same shape as the concrete embedding type equipment when concrete is placed, and an anchor member is screwed to the back surface of the punching die By placing the concrete in such a state, the anchor member can be embedded in the hardened concrete.
[0007]
In this configuration, the concrete embedded equipment is fixed in the concrete insertion recess by a fixing screw screwed into the female screw hole of the anchor member. By removing the, the concrete buried type equipment can be easily separated from the concrete.
[0008]
When the concrete buried equipment is a drain body of a vertical drainage roof drain provided with a drain tray and a drain pipe portion coupled downward from the drain tray, the drain of the drain body The drain main body can be detachably fixed by screwing the fixing screw inserted into the receiving tray from the surface side into the female screw hole of the anchor member.
[0009]
Furthermore, the concrete buried type equipment includes a drain pan formed in a substantially L-shaped cross section by a horizontal edge portion and a vertical edge portion, and a drain pipe portion coupled backward from the vertical edge portion of the drain tray. Even in the case of the drain body of the lateral drainage roof drain, the drain main body is screwed into the female screw hole of the anchor member by screwing the fixing screw inserted from the surface side into the drain receiving tray of the drain body. It can be fixed detachably.
[0010]
  In addition, the present inventionIsA concrete embedded type equipment device embedded in a concrete surface and fixed to concrete by an anchor provided on a lower surface, and the fixed screw inserted into the concrete buried type equipment device from the surface side can be screwed together. An anchor member that has a female screw hole and is to be embedded in the concrete, and the anchor screw is screwed into the female screw hole of the anchor member, thereby fixing the anchor member to the concrete buried type equipment. Fixing equipment for concrete buried type equipment, which is held on the back sideIs used.
[0011]
In this configuration, the concrete embedded type equipment holding the anchor member on the back surface is temporarily fixed on the concrete formwork, and the concrete is hardened by placing concrete around the concrete embedded type equipment. The concrete embedded equipment is removably fixed by the anchor member embedded in the inside. At the time of dismantling the building, the concrete embedded equipment can be easily detached from the concrete by removing the fixing screw screwed into the anchor member.
