Description

The present invention relates to an anchor tool installed at an installation site having a base and a waterproof layer formed on the surface thereof, and an installation structure of the anchor tool.

When installing a structure such as a photovoltaic power generation facility on the roof of a building, a reliable fixing means that can withstand rain, wind, earthquake, etc. is required. For that purpose, it is common to mechanically fix the structure and the floor of the roof with anchor bolts. Here, a waterproof layer may be provided with a waterproof sheet, a waterproof paint, or the like on a base such as concrete constituting the floor of the roof. When an anchor bolt is placed in an installation portion having such a waterproof layer, a through hole is formed in the waterproof layer, and the waterproof function of the waterproof layer is impaired at this portion.

From the above background, a method of directly fixing a plate or a concrete block in which anchor bolts are integrally provided in advance with an adhesive may be adopted for the floor portion having a waterproof layer.

Alternatively, a method may be adopted in which anchor bolts are placed on the floor having a waterproof layer and then the penetrating portion of the waterproof layer is waterproofed with a caulking material.

Further, Patent Document 1 describes the following post-installed foundation anchors. The female screw hole of the tubular base part is screwed into the male screw part of the fixing anchor fixed to the base such as concrete, and the hat member is placed on the tip side of the tubular base part. Then, the installation object fixing bolt is screwed into the female screw hole of the tubular base component through the hole in the top plate portion of the hat member, and the hat member is placed between the tip surface of the tubular base component and the rotation operation portion of the installation object fixing bolt. By sandwiching and tightening, the grounding plate portion of the hat member is fixed in a state of being grounded to the surface of the base. After that, the cover member is externally inserted into the protruding bolt part of the bolt for fixing the installation object, and the cover member is sandwiched between the nut screwed to the protruding bolt part and the rotation operation part and tightened, so that the cover member is the tip of the hat part. It is fixed so as to cover the side. According to this post-installed foundation anchor, it is easy to assemble, and the size of the pilot hole drilled in the concrete base can be set to the minimum size that can fix the anchor for fixing, and the anchor for fixing can be fixed. Since the prepared hole for fixing the concrete is simply covered with a tubular base part, a hat member and a cover member, it is said that waterproofing treatment around the construction site can be performed easily and efficiently in a short time (claims, invention). See effect).

(A) is a perspective view showing the installation site where the waterproof layer is partially removed to expose the base and the anchor tool, and FIG. 2 (B) shows the situation where the anchor tool is installed at the installation site. 3A is a cross-sectional view showing the installation site and the anchor tool separately, and FIG. 3B is a cross-sectional view showing the situation where the anchor tool is installed at the installation site. be.

The anchor tool and its installation structure of the present embodiment are, for example, on the rooftop of a building, in an installation portion R where a waterproof layer 2 is formed on the surface of a concrete base 1 constituting the skeleton, a photovoltaic power generation device, and a wood deck. , It is used as a fixing means for installing various structures such as a water tank.

With reference to the drawings, the anchor tool 10 has a fixing member 11 having a threaded portion 12 having a male screw formed at least on the upper end side and an anchor portion 13 embedded in the base 1 on the lower end side, a threaded portion 12, and a threaded portion 12. The waterproof layer 2 is provided at the lower ends of the first sleeve portion 15 and the first sleeve portion 15 that watertightly covers the peripheral surface of the fixing member 11 with the anchor portion 13 exposed so as to spread around the fixing member 11. A first sealing member 14 having a sheet-like first flange portion 16 that can be watertightly adhered to the surface is provided.

In this example, as the fixing member 11, a full-threaded bolt (also referred to as a shredded bolt) having a male screw formed over the entire length is used. As the material of the first sealing member 14, a material having elasticity and waterproofness is adopted, and for example, rubber, a resin material, asphalt roofing, or the like is used. Vulcanization adhesion is used as a means for watertightly providing the first sleeve portion 15 on the fixing member 11. According to the vulcanization adhesion, since the thread groove of the fixing member 11 can be filled up to the valley bottom by the first sleeve portion 15, there is no gap between the first sleeve portion 15 and the fixing member 11, and the fixing member 11 is surely filled. It can demonstrate water stopping performance.

In order to construct the anchor tool 10, a part 3 of the waterproof layer 2 is removed to form a portion 3 in which the base 1 is exposed in a predetermined area of the installation portion R, and a pilot hole 4 is formed therein. At this time, the range in which the waterproof layer 2 is removed can be covered by the first flange portion 16, and the range in which the first flange portion 16 and the waterproof layer 2 adhere to each other can be sufficiently secured. .. Then, the anchor portion 13 is embedded in the drilled pilot hole 4, the fixing member 11 of the anchor tool 10 is fixed in an upright state, and the first flange portion 16 is watertightly adhered to the surface of the waterproof layer 2. .. As a means for fixing the anchor portion 13 in the prepared hole 4, for example, a chemical anchor (registered trademark) using a synthetic resin that cures in a short time or a metal anchor such as a driving type can be used depending on the situation. can. As the adhesive for adhering the first flange portion 16 to the waterproof layer 2, an adhesive having excellent adhesive performance is selected in consideration of the materials of both.

The anchor tool 10 installed in this way can fix a desired structure to the installation portion R by using the screw portion 12 on the upper end side. Further, the peripheral surface of the fixing member 11 and the first sleeve portion 15 are watertightly closed, and the first flange portion 16 and the waterproof layer 2 are also watertightly closed. Water does not reach the portion 3 where the waterproof function of the waterproof layer 2 is lost by exposing the base 1 in the portion R from the outside. Since a wide adhesive area can be obtained between the peripheral surface of the fixing member 11 and the first sleeve portion 15 and between the first flange portion 16 and the waterproof layer 2, high watertightness can be obtained, so that the base 1 can be used. The risk of water intrusion can be eliminated.

Further, the anchor tool 10 and the waterproof layer 2 have a mechanically independent structure. At the same time, the periphery of the anchor portion 13 is a region where the waterproof layer 2 is removed and the first flange portion 16 is not adhered to the waterproof layer 2, and this region can function as a displacement absorbing member. Therefore, the load from the structure does not directly act on the waterproof layer 2, and even if the anchor tool 10 is displaced by the load acting from the structure, the peeling force and the shearing force act on the waterproof layer 2. Since it is difficult to do so, stable water stopping performance can be obtained. Further, even if the anchor tool 10 is damaged by an excessive external force, the influence on the waterproof layer 2 can be limited.

The anchor tool of this example can provide a product with high reliability in waterproof performance by vulcanizing and adhering the sheet member to the bolt member in advance at the factory. Further, by selecting the material of the sheet member in consideration of the material of the waterproof layer, it is possible to obtain high adhesive strength without adversely affecting the waterproof layer.

Therefore, water does not reach the portion 3 from which the waterproof layer 2 has been removed in the installation portion R from the outside. Therefore, it is possible to reliably prevent water from entering the base 1. Further, the anchor tool 40 and the waterproof layer 2 have a structure that is mechanically independent, and the region of the fourth flange portion 46 that is not adhered to the waterproof layer 2 exists around the main body portion 41a, so that the anchor tool 40 is formed. Even if a load acts on the waterproof layer 2 to cause displacement, it becomes difficult for a peeling force or a shearing force to act on the waterproof layer 2. Therefore, it is possible to obtain stable waterproof performance.

[7th Embodiment]
9A and 9B relate to a seventh embodiment of the present invention, FIG. 9A is a cross-sectional view showing the installation site and the anchor tool separately, and FIG. 9B shows the anchor tool installed at the installation site. It is sectional drawing which shows the situation.

In this example, in the first embodiment, the central portion of the first flange portion 16 of the first sealing member 14 is curved to form a resin pocket 14a formed of a recess in the central portion of the lower surface thereof, and the fixing member is formed. When the anchor portion 13 of 11 is embedded in the prepared hole 4 by a chemical method, the synthetic resin Q overflowing on the surface of the base 1 is configured to be stored in the resin pocket 14a.

In the chemical anchor, the synthetic resin Q overflows to the surface of the base 1, whereby it is confirmed that the gap between the prepared hole 4 and the anchor portion 13 is surely filled with the synthetic resin. However, usually, it is necessary to wipe off the synthetic resin overflowing on the surface. However, if it is configured as in this example, when the anchor portion 13 of the fixing member 11 is inserted into the prepared hole 4, the synthetic resin Q that overflows on the surface of the base 1 is put into the resin pocket of the first sheet member 14. Since it can be stored in 14a, there is an advantage that it is not necessary to remove the overflowing synthetic resin Q.

[Other embodiments]
The installation site where the anchor tool of the present invention is installed is the outside of the roof of a building, a roof, a balcony, a waterproof floor such as a kitchen, a waterproof wall, a road, or the like having a waterproof layer on the surface of the base. The waterproof layer is generally formed of a coating film or a waterproof sheet, but is not limited thereto.

In each of the above embodiments, the fixing member and the nut member are generally made of a metal having a surface treatment such as plating, but may be a synthetic resin or a composite material.

In each of the above embodiments, the material of the first to fifth sealing members is not particularly limited as long as it is impermeable and has good adhesiveness to the waterproof layer. If the waterproof layer at the installation site is made of a waterproof sheet, it may be made of the same material.

In each of the above embodiments, the planar shape of the first to fifth flange portions is rectangular, but other planar shapes such as a circle and an ellipse may be used.

In each of the above embodiments, the anchor portion of the bolt member and the lower bolt member embedded in the prepared hole of the base are male threads, but a surface shape having appropriate irregularities other than the threads may be used.

As a means for providing the first to fifth sleeve portions in a watertight manner, an adhesive capable of ensuring watertightness may be used in addition to the vulcanization adhesive. Alternatively, the surface of the first to fifth sleeve portions may be tightly bound with a hose band, a binding band, or the like to impart watertightness. By doing so, it is possible to retrofit the first to fifth sleeve portions to the bolt member and the nut member at the construction site.

In the first to fifth flange portions, the portion that is not adhered to the waterproof layer may be positively provided with slack to widen the movable range when the anchor tool is displaced.

The range in which the waterproof layer is removed at the installation site may be as small as possible, and the area where the first to fifth flange portions are not adhered to the waterproof layer may be reduced. This makes it possible to further improve the waterproofness of the flange portion.

The fixing member of the fourth embodiment may be used as the fixing member of the fifth embodiment by inverting the top and bottom. On the contrary, the fixing member of the fifth embodiment may be turned upside down and used as the fixing member of the fourth embodiment.

Even if the resin pocket of the seventh embodiment is formed on the nut member in the third embodiment, the main body portion in the fourth and fifth embodiments, and the fifth seal member in the sixth embodiment. good.

In addition to being used for post-construction, the anchor tool of the present invention can be applied even when it is newly constructed.
