Description

The present invention relates to a fixture for fixing other objects, which has an installation support part with a first fixing part to a mounting base, and an installation support part with a second fixing part for fixing an upper object to be fixed so as to be freely displaceable up and down, and the installation support part has a vertically tubular main body part with the first fixing part at its lower end and a roof part closing the upper end of the main body part, and the installation support part has a eaves part that extends outward from the peripheral side surface of the main body part and the second fixing part is disposed at the position of the extended end of the eaves part.

In the past, the applicant proposed a structure in which the second fixing part is located at the extended end of the eaves part in the above-mentioned fixing device for other objects, so that the main body part has a roof part that closes its upper end, making it easy to maintain good waterproofing of the base even if it suddenly rains when attaching it to the base, while allowing the upper and lower fixing positions of the other object to be freely set regardless of the height position of the roof part (see, for example, Patent Document 1).

JP 2020-176698 A

However, when the fixing device for other objects is made smaller, the eaves portion also becomes smaller, which causes a problem that rainwater, etc. entering through the bolt insertion hole of the second fixing portion arranged at the extended end of the eaves portion may reach the upper end of the waterproof layer formed on the peripheral wall portion of the main body portion, compromising the waterproofing of the base.

The object of the present invention is therefore to solve the above problems and to create a fixture that can prevent rainwater from getting on the upper end of the fixture even if the fixture is made small and a waterproof layer is formed on the peripheral wall of the main body.

The first characteristic feature of the present invention is that an object fixing device has an installation support part with a first fixing part to the mounting base, and an object fixing part with a second fixing part for fixing an object to be fixed on the upper side so that it can be displaced up and down, the installation support part has a vertical cylindrical main body part with the first fixing part at its lower end and a roof part that closes the upper end of the main body part, the object fixing part has an eave part that extends outward from the peripheral side surface of the main body part, and the second fixing part is disposed at the position of the extended end of the eave part, and an auxiliary eave part separate from the eave part is attached to the main body part below the second fixing part.

According to the first characteristic configuration of the present invention, even if the eaves portion becomes smaller in order to reduce the overall size, an auxiliary eaves portion separate from the eaves portion is attached to the main body portion below the second fixed portion, so that even if rainwater infiltrates through the bolt insertion hole of the second fixed portion arranged at the extended end of the eaves portion and drips below the eaves portion, the auxiliary eaves portion can block the water and prevent the portion of the periphery of the main body portion below the auxiliary eaves portion from getting wet.
Therefore, even if waterproofing is performed on the base portion that forms a waterproof layer from the first fixing portion to the periphery of the main body portion, by forming the upper end of the waterproof layer below the auxiliary eaves portion, it is possible to prevent rainwater and the like from penetrating into the base through the upper end of the waterproof layer, thereby maintaining a high level of waterproofness of the base.

The second characteristic feature of the present invention is that the second fixing portion is provided on a vertical wall portion that hangs down from the extended end of the eave portion.

The second characteristic feature of the present invention not only achieves the above-mentioned effects of the first characteristic feature of the present invention, but also allows the vertical fixing height of the object by the second fixing part to be set more flexibly along the vertical wall part that hangs down from the extended end of the eaves part.

The third characteristic feature of the present invention is that the outer peripheral edge of the auxiliary eaves is formed into an inclined surface that becomes lower toward the outside.

According to the third characteristic configuration of the present invention, even if rainwater falls on the auxiliary eaves portion, the inclined surface on the outer peripheral edge of the auxiliary eaves portion causes the rainwater to flow in a direction away from the main body portion, making it less likely for the main body portion to get wet.
Furthermore, for example, when forming a waterproof layer around the periphery of the main body part below the auxiliary eaves part, liquid sealant is filled from below the auxiliary eaves part to the upper end of the waterproof layer, and the inclined surface formed on the outer peripheral edge of the auxiliary eaves part guides the tip nozzle of the cartridge that fills the liquid sealant to the periphery of the main body part, improving the reliability of construction and making it easier to ensure waterproofing at the interface between the upper end of the waterproof layer and the main body part.

The fourth characteristic feature of the present invention is that the lower end of the vertical wall portion is formed lower than the outer peripheral edge of the auxiliary eaves portion.

The fourth characteristic feature of the present invention prevents the auxiliary visor from being visible from the outside, improving the appearance of the object fixing device.

The fifth characteristic feature of the present invention is that a waterproof layer can be attached to the peripheral side wall of the main body below the auxiliary eaves.

According to the fifth characteristic configuration of the present invention, by attaching a waterproof layer to the underside of the auxiliary eaves, the upper end of the waterproof layer is protected by the auxiliary eaves, improving the waterproofing of the mounting base.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in Figures 1 to 5, the object fixing device 1 of the present invention is for fixing an object 30 such as equipment, wiring, piping, etc. as a fixing target member to a balcony or rooftop of a building, etc., and comprises an installation support part 4 having a first fixing part 3 for mounting to a building (one example of a mounting base 2) such as a concrete floor on a roof or a balcony, and an object fixing part 6 having a second fixing part 5 for fixing the object 30, which is the upper fixing target, so that it can be freely displaced up and down, integral with the installation support part 4. The installation support part 4 is provided with a vertically tubular main body part 7 having the first fixing part 3 at its lower end, and a roof part 8 closing the upper end of the main body part 7. The object fixing part 6 is provided with a eaves part 9 extending outward from the peripheral side surface of the main body part 7, and the second fixing part 5 is disposed at the position of the extended end of the eaves part 9.

The eaves portion 9 is formed by extending horizontally integrally from the roof portion 8, and to form the second fixing portion 5, a vertical wall portion 10 is provided hanging downward from the extended end of the eaves portion 9, and a first bolt insertion portion 11 is provided in the vertical wall portion 10.
An intermediate support member 15 is provided which has a second bolt insertion portion 14 through which a connecting bolt 12 is inserted together with the first bolt insertion portion 11 and which connects the connecting bolt 12 with a nut 13 .
Furthermore, the second bolt insertion portion 14 is formed as a long hole extending vertically, and a third fixing portion 16 for attaching an object 30 is provided at the upper end of the intermediate support member 15, so that the object 30 can be fixed and supported so as to be freely displaced vertically relative to the object fixing device 1.
The first bolt insertion portion 11 is formed in a square hole, and the connecting bolt 12 is configured as a square root bolt that is fitted into the square hole so as to be non-rotatable.

As shown in Figures 1 to 3, the intermediate support member 15 is formed in a generally box-like shape with vertical walls 17 formed on each of the four peripheral surfaces, and a second bolt insertion portion 14 is formed in each of the vertical walls 17.

As shown in Figures 3 and 5, an auxiliary eave portion 20, separate from the eave portion 9, is attached to the main body portion 7 below the second fixing portion 5, and a waterproof layer 21 (Figure 5) can be attached to the peripheral side wall of the main body portion 7 below the auxiliary eave portion 20.
Incidentally, the above-mentioned waterproof layer 21 may be a coating waterproofing in which a waterproof coating film is formed, or, in addition to coating waterproofing, there may be sheet waterproofing in which a waterproof sheet is attached to the peripheral surface of the main body. In the case of sheet waterproofing, although not shown, generally a stainless steel band is wrapped around the top of the attached sheet to prevent the waterproof sheet from slipping off, and a liquid sealant is filled between the top of the waterproof sheet and the underside of the auxiliary eave portion 20.

The outer periphery of the auxiliary eaves 20 is formed into a sloping surface that becomes lower toward the outside, and due to this sloping surface, even if rainwater falls on the auxiliary eaves 20, the rainwater is directed in a direction away from the main body 7, making the main body 7 less likely to get wet. In addition, for example, when forming a waterproof layer around the periphery of the main body 7 below the auxiliary eaves 20, when filling the waterproof layer from below the auxiliary eaves 20 to the upper end of the waterproof layer with liquid sealant, the sloping surface formed on the outer periphery of the auxiliary eaves 20 guides the tip nozzle of the cartridge that fills the liquid sealant to the periphery of the main body 7, improving the reliability of the construction and making it easier to ensure waterproofing at the interface between the upper end of the waterproof layer and the main body 7.
