Description

  The present invention relates to a technique for installing a solar energy utilization device such as a solar battery panel installed on the roof of a building such as a house, and more specifically, a fastening for fixing a member while preventing water leakage from the roof. Concerning ingredients.

  Conventionally, in a solar energy utilization device such as a solar battery panel installed on the roof of a building such as a house, a configuration in which the solar energy utilization device is installed with installation fixtures disposed at a plurality of locations on the roof is known. It has been. Moreover, the installation fixture is installed on roof materials, such as a slate tile, and the form fix | screw fixed with respect to the roof base plate is known, and the literature which discloses this form also exists ( For example, see Patent Document 1.)

  And, as disclosed in Patent Document 1, conventionally, in order to fix the installation fixture (fixing bracket), a roof hole (flat roof material) with a leading hole, and a caulking agent is injected into the leading hole, Then, the form which drives a screw into a field board through a front hole is known. In this embodiment, the leakage of rainwater by the caulking agent is intended for the tip hole or the hole formed in the base plate by driving a screw.

  As described above, in the construction of a conventional solar energy utilization device, measures against water leakage by a caulking agent have been taken with respect to fixing an installation fixture on a roof.

  On the other hand, Patent Document 2 discloses a sealing screw, and a sealing material made of a synthetic resin film is attached to a threaded portion (fitting portion) of a male screw.

JP 2008-274647 A JP 58-28007 A

  In the conventional construction method for injecting the caulking agent, the trouble of injecting the caulking agent is generated. In particular, when installing solar energy utilization devices so as to cover a wide area of the entire roof, the number of solar energy utilization devices to be installed is increased, and each unit is securely connected and fixed to the roof side. It is necessary to use a number of installation fixtures. In addition, each installation fixture also needs to be screw-fixed at a plurality of locations, so the number of injections of the caulking agent is assumed to be several hundreds or more. And from this, it is considered that a coherent work time has occurred due to the injection work of the caulking agent, and this work time affects the total construction time of the solar energy utilization device.

  However, in those skilled in the art of roof construction and repair, since the installation of solar energy utilization devices has become widespread, it has become customary to take measures against water leakage by using a caulking agent in relation to the roof. In particular, even in the installation of solar cell panels where demand and spread are rapidly expanding, it is considered that there was no particular question about the point that the operation of injecting the caulking agent was required.

  However, as described above, the time for the operation of injecting the caulking agent affects the total construction time of the solar energy utilization device. For this reason, the inventors of the present application pay attention to the time for injecting the caulking agent, and in order to shorten the total construction time, the caulking agent is inadvertently being worked on, but the caulking agent is dared. A new technology that can take measures against water leakage without injecting water was studied.

  Moreover, in the structure disclosed by patent document 1, it is set as the form by which a waterproof sheet (waterproof cover) is laid by the front surface side of a roof material, That is, between a roof material and a field board, ie, a roof material. In the configuration where the waterproof sheet is laid on the front side of the base plate on the back side, a hole is formed in the waterproof sheet by a screw breaking through the waterproof sheet. Need to be sealed.

  In particular, in the case of a form in which a waterproof sheet is laid on the front side of the field board on the roof of an existing house, there is no need to lay a waterproof sheet on the roof material as in Patent Document 1, and the existing waterproof There is an advantage that the sheet can be used as it is. For this reason, about the form by which a waterproof sheet is laid on the front surface side of such a field board, the technique which can perform a water leak countermeasure without performing the injection | pouring operation | work of a caulking agent is anticipated.

  In addition, in patent document 1, since it is a form which provides a waterproof sheet in the front surface side of a roofing material, even if such a subject is not conceivable even if patent document 1 is referred, inventors, Considering the actual form of the roof of the existing house, it has been studied repeatedly.

  On the other hand, it is also considered to use a sealing screw as disclosed in Patent Document 2 to ensure the sealing performance of the screwed portion with a synthetic resin film.

  However, from the viewpoint of ensuring high waterproofness, it is assumed that it is required to use a caulking agent having adhesiveness such as a butyl caulking agent. When the caulking agent having such adhesiveness is deposited on the screw, it is necessary to prevent the caulking agent from sticking. If the caulking agent becomes sticky, for example, when it is assumed that a plurality of screws are accommodated in a bag, box, pocket, etc., the caulking agent adheres to the inside of the bag or even to the work gloves of the worker. There is also a concern that the agent will be peeled off and the waterproofness originally required cannot be secured.

  In addition, as another problem, if the screws are attached to each other by the caulking agent, the screws must be separated and used each time, resulting in poor workability.

  Therefore, in view of the above problems, the present invention proposes a fastener with a sealing function having a novel structure that makes it possible to improve workability without requiring a caulking agent injection operation. Is.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

In the invention according to claim 2,
Compared to the case where only the surface of the sealing material is directly exposed to the outside, the covering material can suppress stickiness of the sealing material. For example, multiple fasteners with a sealing function can be accommodated in bags, boxes, pockets, etc. When this is assumed, it is possible to prevent the occurrence of a problem that the caulking agent is peeled off due to adhering to the inside of the bag or further to the work gloves of the worker, and the originally required waterproofness cannot be secured. In addition, it is possible to effectively prevent a problem that the fasteners with a sealing function stick to each other with the sealing material, and it is possible to prevent deterioration of workability.

In the invention according to claim 3,
For example, it is possible to suppress the amount of the covering material used by covering the sealing material with the covering material only at a necessary portion. For example, in the longitudinal direction of the sealing material, it is conceivable that the entire range excluding both ends is covered with a coating material, and the peeling of the sealing material is reliably suppressed at the coating part.

For example, when it is assumed that a plurality of fasteners 1 with a sealing function are accommodated in a bag, a box, a pocket, etc. It is possible to prevent the occurrence of a problem that the caulking agent is peeled off by adhering to the inside or even the work gloves of the worker, and the waterproof property originally required cannot be secured.

The figure shown about one Example of a fastener with a sealing function. The figure shown about the construction example of a solar cell panel. The figure shown about fixation of the bracket member using a fastener with a sealing function. The figure shown about the state sealed by the fastener with a sealing function. The figure shown about embodiment of this invention in the other accommodation specification of a roof material.

  FIG. 1 is an overall view of a fastener 1 with a sealing function according to an embodiment of the present invention. The fastener 1 with a sealing function of the present embodiment is configured in the form of a fastener having a screw structure, and a screw portion 3 in which a spiral thread is formed, and a head provided at one end of the screw portion 3. The unit 5 is configured.

  The screw portion 3 is covered with the sealing material 7 in a range F in a predetermined range in the longitudinal direction of the screw portion 3. As will be described later, the seal material 7 functions as a seal material (caulking agent) for sealing a gap between the hole into which the screw portion 3 is inserted and the screw portion 3. For example, the butyl coking is used. The use of commercially available agents is conceivable.

  The form in which the screw part 3 is covered with the sealing material 7 is not particularly limited. For example, as shown in FIG. 1, a plate-shaped seal having a thickness of several mm (for example, 1.0 mm to 3.0 mm) It is conceivable to cover the screw portion 3 by winding the material 7 around the screw portion 3. In this case, when the butyl caulking agent is used, the sealing material 7 can be integrated with the screw portion 3 by adhesion due to the adhesive force of the butyl caulking agent itself.

  In addition to this, the screw part is covered with a sealing material by spraying, the screw part is immersed in the sealing material and then solidified, or the screw part is inserted into a semi-solid sealing material in a predetermined form, etc. And the form etc. with which a thread part is coat | covered with a sealing material can be considered.

  When a member exhibiting adhesiveness such as a butyl caulking agent is used for the sealing material 7, the surface of the sealing material 7 is sticky and sticks, so that a problem caused by this sticking does not occur. Therefore, the surface of the sealing material 7 is covered with the covering material 9.

  As will be described later, the covering material 9 functions as a sealing material (caulking agent) for sealing a gap between the hole into which the screw portion 3 is inserted and the screw portion 3. When one sealing material is used, the covering material 9 functions as the second sealing material. For example, it is possible to use a commercially available sealing tape made of polytetrafluoroethylene (Teflon (registered trademark)).

  This seal tape is also known as “unsintered tetrafluoroethylene resin tape (raw tape) for sealing” (JIS K 6885), and it is a connecting part of pipes for conducting liquids and gases such as water pipes and air pipes. It is used to fill gaps that occur in

  In addition, by using the covering material 9 as a belt-like tape member as in this sealing tape, the sealing material 7 can be easily covered by winding the covering material 9. In addition, the sealing material is coated with a coating material by spraying, or the screw portion coated with the sealing material is dipped into the coating material and then solidified, or the semi-solid coating material in a predetermined form is sealed. For example, the sealing material may be covered with a covering material by inserting a screw portion covered with

  In addition, the outer surface 9a of the covering material 9 in a state where the sealing material 7 is covered constitutes a non-adhesive layer that does not exhibit adhesiveness. Note that “not sticky” means that the fasteners 1 with the sealing function that are covered with the covering material 9 do not stick to each other, and the outer surface 9a is touched with fingers. It means that it is possible to form a situation in which there is no sticking, and even when the outer surface 9a is touched with the work gloves on, the fibers of the work hand are hardly attached to the outer surface 9a.

  In addition, about the coating | covering material 9, the outer surface 9a after coat | covering the sealing material 7 should just be what does not exhibit adhesiveness, and about the inner surface of the coating | covering material 9, it may exhibit adhesiveness. .

  In addition, in the embodiment shown in FIG. 1, the screw portion 3 is covered with the sealing material 7 and the sealing material 7 is covered with the covering material 9 automatically by a mechanical device or manually. It may be.

  As described above, in the embodiment of the present invention, the outer surface of the covering material 9 in a state where the screw portion 3 is covered with the sealing material 7, the sealing material 7 is covered with the covering material 9, and the sealing material 7 is covered. The fastener 1 with a sealing function which does not exhibit adhesiveness is comprised.

  According to this structure, since the sealing material 7 is covered with the covering material 9, the sealing material 7 is not sticky, and the fastener 1 with the sealing function can be easily handled. In addition, since the paper is not used, various problems that occur when using the paper, that is, the necessity to remove the paper, the scattering of the paper, and the dust can remain on the roof. Various problems such as the necessity of cleaning, the necessity of subsequent cleaning work, and the necessity of disposal. Furthermore, since the sealing material 7 is covered with the covering material 9 and the sealing material 7 is protected by the covering material 9, it is possible to prevent the occurrence of problems such as deterioration, damage, and omission of the sealing material 7.

  Next, the example which constructs the solar cell panel 27 using the fastener 1 with a sealing function as shown in FIG. 2 is demonstrated. Roof materials 24 a, 24 b... Are installed on the base plate 22 via the waterproof sheet 23, and the roof materials 24 a, 24 b. The solar cell panel 27 is placed and fixed.

  As shown in FIG. 3, a waterproof sheet 23 is laid on the upper surface side (front side) of the base plate 22, and roofing materials 24 a and 24 b are laid on the waterproof sheet 23. The roofing materials 24a and 24b are provided so as to partially overlap so that the water side is on the upper side, and through holes 41a and 41b penetrating in the vertical direction are formed in the overlapping portions. The through holes 41a and 41b are provided to allow the fastener 1 with a sealing function to pass through.

  The installation fixture 50 is installed on the front side of the roofing material 24a / 24b, the bracket member 51 to which the mounting member 26 of the solar cell panel 27 is connected, and the bracketing member 51 as the roofing material 24a / 24b and the roofing material 24a / 24b. It is a fastener for fastening to the base plate 22 via the waterproof sheet 23 on the back side, and has the fastener 1 with a sealing function of the embodiment described above.

  The bracket member 51 includes an installation plate portion 51a installed on the upper surface side (front surface side) of the roof material 24a and a connection portion 51b to which the mount member 26 (see FIG. 1) of the solar energy utilization device is connected and fixed. It has the composition to have. Moreover, the adhesive tape member 51c is affixed on the lower surface (back surface) of the installation board part 51a, By sticking this tape member 51c on the roof material 24a, the bracket member 51 is attached to the roof material 24a. Can be temporarily fixed.

  In addition, as the tape member 51c, the butyl tape etc. which are known as what exhibits a water stop function (sealing function) can be utilized. Further, the tape member 51c is a separate body from the bracket member 71, and may be appropriately used during construction.

  Moreover, the fastener 1 with a sealing function that functions as a fastening member includes a screw portion 3 whose tip side is inserted into the base plate 22 and a head portion 5 provided on the rear end side of the screw portion 3. .

  This fastener 1 with a sealing function fixes the bracket member 51 to the base plate 22, and the fastener 1 with a sealing function with respect to the through hole 51m formed in the installation plate portion 51a of the bracket member 51. The screw portion 3 is inserted, and the screw portion 3 is screwed into the base plate 22 so that the tip of the screw portion 3 breaks through the waterproof sheet 23.

  The installation plate 51a of the bracket member 51 is pressed from above by the head 5 of the fastener 1 with a sealing function, and water enters from the through hole 51m between the head 5 and the installation plate 51a. A packing 8 is provided to prevent this. The packing 8 can be attached to the fastener 1 with a sealing function in advance.

  Moreover, as shown in FIG. 3, the screw part 3 of the fastener 1 with a sealing function is in a state where a sealing material 7 and a covering material 9 are covered. The sealing material 7 functions as a sealing member, and, for example, a butyl caulking agent that has been widely used conventionally can be adopted as described above.

  Moreover, as shown in FIG. 3, the sealing material 7 shall be attached to the front end side of the screw part 3 of the fastener 1 with a sealing function. More specifically, in the length direction of the screw portion 3 of the fastener 1 with the sealing function, the range F in which the seal material 7 is provided is a case where the portion of the screw portion 3 inserted into the base plate 22 is the effective insertion range Y. It is assumed that at least a part of the effective insertion range Y is included. In other words, when the effective insertion range Y is the range from the tip 3a to the midway portion 3b, the boundary portion Fa on the tip 3a side of the range F is disposed closer to the tip 3a than the midway portion 3b. And

  As shown in FIG. 4, when the fastener 1 with a sealing function is inserted into the base plate 22 so as to penetrate the waterproof sheet 23, the sealing material 7 attached around the screw portion 3, and the sealing material The covering material 9 covering 7 is raised so as to be pushed back to the base plate 22 and is deposited around the hole 31 formed in the waterproof sheet 23. And the hole 31 of the waterproof sheet 23 is sealed by the sealing material 7 and the covering material 9 deposited in this way.

  In addition, the hole 31 of the waterproof sheet 23 may be formed in advance in the waterproof sheet 23 in addition to being formed by passing the tip of the fastener 1 with a sealing function.

  With the above configuration, the installation fixture 50 can be installed without requiring a caulking agent injection operation.

  That is, first, as shown in FIG. 3, the bracket member 51 is installed on the roof material 24a so that the positions of the through holes 51m of the installation plate portion 51a are aligned with the through holes 41a and 41b. Next, the fastener 1 with the sealing function in which the screw portion 3 is covered with the sealing material 7 and the covering material 9 is inserted from the through hole 51m of the installation plate portion 51a, and as shown in FIG. When the tip of the tool 1 penetrates the waterproof sheet 23 and is inserted into the base plate 22, the fixing of the bracket member 51 to the base plate 22 by the fastener 1 with the sealing function is completed.

  As shown in FIG. 4, when the bracket member 51 is fixed, the sealing material 7 and the covering material 9 attached to the periphery of the screw portion 3 are pushed back to the base plate 22. It rises and accumulates around the hole 31 formed in the waterproof sheet 23.

  The hole 31 of the waterproof sheet 23 is sealed by the sealing material 7 and the covering material 9 deposited in this manner, and the intrusion of water into the hole 31 is prevented by the sealing material 7 and the covering material 9. It becomes possible to prevent water leakage due to passing through the hole 31 formed in the waterproof sheet 23. Thus, the simple work of fastening the fastener 1 with a sealing function can be used as a substitute for the caulking agent injection work.

  4 is assumed to be present at a plurality of locations for one bracket member 51. That is, for example, one bracket member 51 is fastened with the fastener 1 with a sealing function at five locations. Therefore, by applying this embodiment instead of the caulking agent injection operation, the operation time can be greatly shortened.

  As described above, the fixing structure of the fixed member using the fastener 1 with the sealing function is realized, and the fastener 1 with the sealing function is screwed to the base plate 22 (fixing member) at the tip side. The screw member 3 for fastening the bracket member 51 (fixed member) to the base plate 22 by being inserted is covered with the seal member 7, and the outer surface of the seal member 7 is adhesive. When the screw portion 3 is inserted into the base plate 22, the seal member 7 and the cover material 9 are raised so as to be pushed back to the base plate 22, so that the sealing material and The sealing performance by the covering material is exhibited.

  And since the sealing material 7 is coat | covered with the coating | covering material 9, the sealing material 7 does not stick, and handling of the fastener 1 with a sealing function becomes easy. In addition, since the paper is not used, various problems that occur when using the paper, that is, the necessity to remove the paper, the scattering of the paper, and the dust can remain on the roof. Various problems such as the necessity of cleaning, the necessity of subsequent cleaning work, and the necessity of disposal.

  Moreover, since the sealing material 7 is covered by the covering material 9 and the sealing material 7 is protected by the covering material 9, it is possible to prevent the occurrence of problems such as deterioration, damage, and omission of the sealing material 7.

  In addition, by making the covering material 9 function as a second sealing material for sealing the gap, there is no need to remove the covering material 9 after construction, and more together with the sealing material 7 covered with the covering material 9 It becomes possible to exhibit high sealing performance (waterproofness).

  As shown in FIG. 5, in the storage specification of the roof material in which a plurality of roof materials 24 c, 24 d, and 24 e are stacked, a space 28 is provided between the upper (water-side) roof material 24 d and the field plate 22. It is formed. Even in such a storage specification, when the above-described fastener 1 with a sealing function is used, it is possible to deposit the sealing material 7 and the covering material 9 using the space 28, thereby the sealing material 7.
