Description

  The present invention relates to a wire drawing structure and a wire drawing tool in which a wire is drawn into a building from above a roof material via a wire drawing tool.

  In the past, the applicant of the present invention, from the roof material laid on the roof structure such as rafters and field boards constituting the roof of the building into the building, such as the electric wire from the solar cell module, the antenna line from the TV antenna, etc. The wire drawing-in tool for drawing in a wire is proposed (patent documents 1 and patent documents 2). These wire rod drawing tools include a container-like main body member whose upper end surface and eaves side end surface are open, and a lid member that covers the upper portion of the main body member. The main body member is formed with an insertion hole penetrating vertically in a container shape.

  In attaching the wire drawing tool to the roof material, first, the main body member is attached on the roof material so that the insertion hole matches the through hole formed in the roof structure and the roof material. And a wire is introduced into the inside of the main body member from the eaves side end face, and is extended into the building through the insertion hole and the through hole. Thereafter, the lid member is attached to the main body member from above to complete the drawing of the wire and the attachment of the wire drawing tool. In this way, by drawing the wire rod into the building via the wire rod drawing tool, the intrusion of rainwater along the wire rod into the building is prevented.

  In said wire rod drawing tool, while preventing the contact of a wire to the through-hole formed in the roof structure and the roof material, and the penetration of rainwater below the roof structure, a cylindrical member or tube It has a shaped part. Specifically, the wire rod retractor disclosed in Patent Document 1 includes a cylindrical sleeve material that is inserted into the through hole from above the main body member through the insertion hole. Moreover, in the wire rod drawing tool of Patent Document 2, a cylindrical guide portion that is inserted into the through hole is provided integrally with the main body member.

  However, in the technique of Patent Document 1, if the main body member is attached to the roof material in a state where the insertion hole of the main body member is shifted from the through hole, there is a possibility that the sleeve material cannot be inserted. In the technique of Patent Document 1, since the sleeve material is inserted into the insertion hole and the through hole from above the main body member, the lid member can be attached to the main body member even when the sleeve material is not sufficiently inserted. Therefore, when attached in such a state, there is a possibility that rainwater may enter the building through between the sleeve material and the insertion hole and the through hole.

  On the other hand, in the technique of Patent Document 2, when the through hole is formed to be inclined from the direction perpendicular to the upper surface of the roof material, the guide member is inserted into the through hole and the main body member is attached to the roof material. The lower surface is inclined with respect to the upper surface of the roofing material, and the main body member may not be attached to the roofing material.

  For this reason, in the conventional techniques such as Patent Document 1 and Patent Document 2, it is necessary to carefully perform the attaching operation of the main body member and the drilling operation of the through hole to the roof structure and the roof material, It took time and effort to draw the wire.

Japanese Patent No. 4869141 Japanese Patent No. 5586574

  Then, this invention makes it a subject to provide the wire drawing-in structure and wire drawing-in tool which prevent the penetration | invasion of rain water into a building, and the drawing-in operation | work of a wire is easy in view of said situation.

  In order to solve the above-mentioned problems, the wire rod drawing structure according to the present invention is a wire rod drawing structure in which a wire rod is drawn into a building from above a roof material laid on a roof structure via a wire rod drawing tool. The wire rod drawing tool includes a guide member having a cylindrical guide portion penetrating the roof material and the roof structure, and a flange portion extending outward from the upper end of the guide portion; A flat plate-like substrate portion mounted on the roof material so as to cover the upper portion of the guide member, and an opening through which the substrate portion is inserted larger than the diameter of the flange portion and the flange portion is inserted Projecting inwardly from the inner peripheral surface of the opening and extending upward from the flange, and extending the opening from the base plate and opening the eaves side. A main body member having a surrounding peripheral wall portion, and attached to the main body member; A lid member that covers the outer portion from the outside and closes the peripheral wall portion from above, and a wire is introduced into the peripheral wall portion from the eaves side, and passes through the opening and the guide portion. Is being drawn into the building. "

  Here, examples of the “roof structure” include field boards and rafters. Examples of the “roof material” include sheet metal roof material, slate, asphalt single, and tile.

  In addition, “wires” include “solar cell modules, wind power generators, commercial power lines, lighting devices, etc.”, “antenna wires connected to antennas”, “phones, the Internet, cable TV, etc.” Examples include “communication lines to be connected”, “distribution pipes connected to solar water heaters and sprinklers”, “pipes connected to air conditioners”, and “other pipes such as gas pipes”.

  The wire lead-in structure of this configuration is such that the guide member is inserted from above into the through-hole formed in the roof material and the roof structure, and the main body member is moved upward so that the upper end of the guide member is fitted into the opening. Install on the roofing material. And it is constructed by extending the wire rod from the eave side where the peripheral wall portion is open to the inside of the main body member, drawing it into the building through the opening portion and the guide member, and attaching the lid member to the main body member from above. Can do.

  According to the wire lead-in structure of this configuration, the opening of the main body member has the protruding portion extending above the flange portion of the guide member, and therefore the guide portion is not sufficiently inserted into the through hole. Even when the eaves portion protrudes high upward from the roofing material, when the main body member is mounted on the roofing material, the projection can abut against the eaves portion and press the guide member downward. Thereby, a guide part can fully be inserted with respect to a through-hole, and the penetration | invasion of rain water into the building which passed between the guide member and the through-hole can be prevented.

  In addition, according to the wire lead-in structure of this configuration, since the guide member is a separate member positioned below the main body member, the guide member is inserted into the roof material and the through hole of the roof structure and protrudes from the roof material. What is necessary is just to mount a main body member on a roof material so that an opening part may be fitted with respect to the collar part of a guide member, and the attachment operation | work of a main body member can be made easy. Moreover, since the guide member is a separate member from the main body member, the main body member can be mounted on the roof material even if the through hole is inclined from the vertical direction with respect to the top surface of the roof material. There is no need to do it carefully.

  Moreover, in addition to said structure, the wire drawing-in structure which concerns on this invention shall be "The said cover member inclines so that it may approach the said board | substrate part, so that it goes to the eaves side."

  By the way, in the wire drawing-in structure, because the wire drawing device through which the wire is inserted communicates with the inside of the building through the opening of the main body member and the guide member, when the temperature of the outside air is low, it passes through the opening and the guide member. When the warm air in the building is introduced into the wire drawing tool, condensation occurs inside the wire drawing tool. At this time, if the slope of the roof to which the wire drawing tool is attached is loose, it is difficult for the water condensed inside the lid member to flow toward the eaves and drops into the building through the opening and the guide member as water droplets. There is a risk that.

  According to the wire lead-in structure of this configuration, the lid member is inclined so that the eaves side is lowered with respect to the substrate part of the main body member, so that water condensed on the inside of the lid member can be easily flowed in the eave direction. It is possible to prevent the condensed water from falling toward the opening. Therefore, even when the wire rod drawing structure of the present configuration is constructed on a roof with a gentle slope, it is possible to prevent water condensed in the wire rod drawing tool from falling into the building.

  The wire rod drawing tool according to the present invention covers a guide member having a tubular guide portion and a flange portion extending outward from the upper end of the guide portion, and an upper portion of the guide member. A flat substrate portion, an opening that is larger than the diameter of the flange portion, penetrates the substrate portion, is inserted into the flange portion, and protrudes inward from an inner peripheral surface of the opening portion. A main body member having a projecting portion extending upward, a peripheral wall portion extending upward from the substrate portion and surrounding the opening portion in a partially open state, and the main body member And a lid member that covers the peripheral wall portion from the outside and closes the peripheral wall portion from above ”.

  The wire rod drawing tool having this configuration is used for the wire rod drawing structure described above. This wire rod drawing tool is used with the part of the peripheral wall portion opened toward the eaves side. In addition, since the projecting portion extends inward from the inner peripheral surface of the opening in the main body member, when the guide member is not sufficiently inserted into the through hole when the wire drawing tool is attached, the projecting portion Can abut against the collar and press the guide member downward. Thus, said effect is exhibited by drawing in a wire into a building using this wire drawing-in tool. In addition, since the wire drawing tool of this configuration uses the guide member as a separate member from the main body member, a mold for molding the main body member is required as compared with the case where the guide member and the main body member are integrated. It can be made small, and the increase in the cost concerning manufacture can be suppressed.

  As described above, as an effect of the present invention, it is possible to provide a wire rod drawing structure and a wire rod drawing tool that prevent rainwater from entering the building and facilitate the drawing operation of the wire rod.

  The first waterproofing material 14 will be described in detail later, but at the construction site where the wire drawing tool 10 is attached, a sheet-like member is rolled into a cylindrical shape, and a plurality of cuts are made at the upper end portion to the outside. It is bent. The first waterproof material 14 is shipped in a sheet-like state in which release paper is pasted on both sides. The second waterproof material 15 has a sheet shape that is slightly smaller than the outer shape of the substrate portion 12a of the main body member 12, and a hole 15a having an inner diameter larger than that of the opening 12d is formed in a portion corresponding to the opening 12d. The second waterproof material 15 is affixed to the lower surface of the main body member 12 in advance when the product is shipped. The first waterproof material 14 and the second waterproof material 15 are formed of a butyl rubber sheet.

  The third waterproofing material 16 is a putty made of a synthetic resin having water resistance, waterproofness and insulating properties such as Plaseal (registered trademark). A predetermined amount of the third waterproof material 16 is bundled at the time of shipment of the product. The fourth waterproof material 17 is foamed rubber. The fourth waterproofing member 17 extends over the entire length in the width direction at the site on the eaves side short side 12c side of the lower surface of the top wall portion 13c of the lid member 13 with respect to the eaves side 13c before the product is shipped. Pasted.

  The guide member 11 of the wire retractor 10 is formed by either synthetic resin injection molding or aluminum alloy casting. The main body member 12 and the lid member 13 are formed by casting an aluminum alloy.

  Next, the construction of a wire drawing structure for drawing the wire 3 from the top of the roofing material 2 into the building using the wire drawing tool 10 will be described. In this embodiment, the case where the roof structure 1 is a field board and the roofing material 2 is a slate is illustrated.

  First, the through-hole 4 having an inner diameter slightly larger than the diameter of the guide portion 11a of the guide member 11 from above is provided so as to pass through the roof material 2 and the roof structure 1 at a portion to which the wire drawing tool 10 in the roof material 2 is attached. Form. Next, the release paper on one side of the sheet-shaped first waterproofing material 14 is peeled off, and with the upper end protruding to some extent from the upper surface of the roofing material 2, the surface from which the release paper is peeled is set to the outside and the through hole 4 is Wrap while pasting on the inner surface. And after excising the part which overlaps in the peripheral direction of the through-hole 4, it is made to make a some incision in the site | part which protrudes from the upper surface of the roofing material 2, and it bends outward, and also on the upper surface of the roofing material 2. paste.

  Thereafter, the release paper on the remaining surface of the first waterproof material 14 is peeled off, and then the guide of the guide member 11 in a state where the collar portion 11b is directed upward to the cylindrical portion of the first waterproof material 14 Insert the part 11a. At this time, the guide member 11 is press-fitted so that the lower surface of the flange portion 11 b of the guide member 11 in the first waterproof material 14 comes into contact with the portion of the first waterproof material 14 attached to the roof material 2. . Thereby, the space | interval between the guide member 11 and the through-hole 4 is sealed by the 1st waterproofing material 14, and infiltration of rain water into a building can be prevented.

  Next, the main body member 12 in a state where the second waterproofing material 15 is attached to the lower surface of the substrate portion 12a, the guide member 11 in the opening 12d with the ridge side short side 12b facing the ridge side. It mounts on the roofing material 2 so that the part 11b may be inserted. Then, the mounting screw 18 passed through the mounting hole 12k from above is screwed into the roof structure 1 to mount the main body member 12 on the roofing material 2.

  At this time, when the guide member 11 is not sufficiently inserted into the through-hole 4 and the flange portion 11b protrudes upward from the roofing material 2, the projection 12f of the main body member 12 contacts the flange portion 11b from above. When the main body member 12 moves downward by tightening the mounting screw 18, the projection 12 f presses the guide member 11 downward. As a result, the guide member 11 is sufficiently inserted into the through hole 4.

  When the main body member 12 is attached to the roofing material 2, the wire 3 is inserted from above into the opening 12d and the guide portion 11a and pulled into the building, and is bent toward the eaves side above the opening 12d to form the peripheral wall portion 12g. The eaves side is extended from the eaves side short side 12c side to the eaves side. At this time, the wire 3 is allowed to pass above the lower part of the first dam portion 12i. Moreover, when drawing in the some wire rod 3 in a building, it arranges in the width direction in the eaves side rather than the opening part 12d.

  Then, the clay-like third waterproofing material 16 is filled into the opening 12d and the guide part 11a from above so as to fill the space between the opening part 12d and the guide member 11 and the wire rod 3 to stop water (see FIG. 2). Thereafter, the lid member 13 is covered from above the main body member 12, and the mounting screw 19 passed through the assembly hole 13d is screwed into the screw hole 12h and tightened. At this time, the fourth waterproof material 17 made of foam rubber attached to the lower surface of the lid member 13 is elastically deformed, and the gap between the lid member 13 and the wire 3 is stopped (see FIG. 1B). . Thereby, it will be in the state where the wire rod drawing tool 10 was attached on the roofing material 2, and the wire rod drawing structure in which the wire rod 3 is drawn into the building via the wire rod drawing tool 10 from the roof material 2 is constructed ( (See FIG. 1 (a)).

  Here, since the top wall central portion 13ca of the top wall portion 13c of the lid member 13 is inclined so as to become lower from the ridge side toward the eave side, in the state where the wire rod drawing structure is constructed, FIG. As shown, the top wall central portion 13ca is inclined so as to approach the substrate portion 12a toward the eaves side. That is, in a state where the wire rod drawing tool 10 is attached to the roof material 2, the ceiling wall center portion 13 ca is inclined so as to become lower toward the eaves side with respect to the upper surface of the roof material 2. And, since the edge of the ridge side that is higher is positioned above the opening 12d, the ceiling wall central portion 13ca has water that evaporates more than the opening 12d when condensation occurs inside the lid member 13. It is possible to easily flow in the direction, and it is possible to prevent the condensed water from falling into the opening 12d.

  Water that has condensed on the inside of the lid member 13 and has fallen to the eaves side from the opening 12d flows down on the substrate part 12a of the main body member 12 to the eaves side, and a pair of first dam parts 12i and a second dam part After being guided to 12j, it is discharged onto the outer roof material 2 from the eaves side edge of the substrate portion 12a.

  On the other hand, the penetration of rainwater that has traveled along the wire 3 into the wire retractor 10 is prevented by the fourth waterproof member 17 that closes the space between the wire 3 and the lid member 13. Moreover, the intrusion of rainwater into the inside of the wire rod drawing tool 10 below the wire rod 3 is blocked by the second dam portion 12j near the eaves side edge of the main body member 12. Even if rainwater enters from between the second dam portion 12j and the peripheral wall portion 12g, it is blocked by the pair of first dam portions 12i on the ridge side and further dammed by the cylindrical dam portion 12e on the ridge side. It can be stopped. Even if rainwater enters the inside of the wire drawing tool 10, it is guided to the eaves side by the pair of first dam portions 12i and the second dam portions 12j and discharged to the outside in the same manner as the water condensed inside. In this way, the cylindrical dam portion 12e, the first dam portion 12i, and the second dam portion 12j are configured such that rainwater is difficult to enter and easily discharged to the outside, so that rainwater is difficult to reach the opening 12d. Intrusion of rainwater or condensed water into the building via the opening 12d and the guide member 11 is effectively prevented.

  As described above, according to the present embodiment, the opening 12d of the main body member 12 has the protruding portion 12f extending upward from the flange portion 11b of the guide member 11, so that the guide to the through hole 4 is provided. Even when the portion 11a is not sufficiently inserted and the flange portion 11b protrudes upward from the roof material 2, the projection 12f abuts against the flange portion 11b from above when the main body member 12 is mounted on the roof material 2. Thus, the guide member 11 can be pressed downward. Thereby, the guide part 11a can be sufficiently inserted into the through hole 4 and rain water can be prevented from entering the building passing between the guide member 11 and the through hole 4.

  Moreover, according to this embodiment, since the guide member 11 is a separate member positioned below the main body member 12, the guide member 11 is inserted into the roof material 2 and the through-hole 4 of the roof structure 1 to be on the roof material 2. What is necessary is just to mount the main body member 12 on the roofing material 2 so that the opening part 12d may be fitted with respect to the collar part 11b of the protruding guide member 11, and the attachment work of the main body member 12 is easy. can do. Further, since the guide member 11 is a separate member from the main body member 12, the main body member 12 can be mounted on the roof material 2 even if the through hole 4 is inclined from the vertical direction with respect to the upper surface of the roof material 2. It is not necessary to carry out the drilling work carefully like this.

  Furthermore, according to the present embodiment, the top wall central portion 13ca of the lid member 13 is inclined so as to become lower toward the eaves side with respect to the upper surface of the roofing material 2, so that the wire rod drawing structure of the present embodiment Even if the roof is constructed with a gentle slope, the water condensed inside the lid member 13 of the wire retractor 10 is more likely to flow toward the eaves than the opening 12d, and the condensed water falls toward the opening 12d. Can be prevented.

  Moreover, according to this embodiment, the protrusion part 12f which protrudes in the opening part 12d of the main body member 12 is protruded from the ridge side to the eaves side. In other words, since the protrusion 12f of the main body member 12 is not protruded from the eave side to the ridge side in the opening 12d, there are the following advantages. More specifically, assuming that the protrusion protrudes from the eaves side to the ridge side in the opening 12d, the wire 3 inserted through the opening 12d and the guide member 11 from above is bent toward the eaves. A protrusion is located inside the bend. In that case, if the curvature of the wire 3 is small, it will be easy to hit the projection, so it is necessary to increase the curvature of the wire 3, and the wire 3 is likely to be disconnected by increasing the curvature. On the other hand, in this embodiment, since the protrusion part 12f is not protruded from the eaves side to the ridge side, it can suppress that the curvature of the wire 3 becomes large, and can suppress the disconnection of the wire 3. Can do.

  Further, according to the present embodiment, since the inner diameter of the opening 12d of the main body member 12 is larger than the outer diameter of the flange 11b of the guide member 11, when the main body member 12 is mounted on the roof material 2, the wire 3 The inner diameter of the portion through which is inserted becomes larger as it goes upward. Thereby, when bending the wire 3 inserted through the opening 12d and the guide member 11 toward the eaves side, the curvature can be reduced, and the same effect as described above can be achieved.

  Moreover, according to this embodiment, since a low site | part is formed in a pair of 1st dam part 12i near the opening part 12d, and the wire 3 is passed over the said site | part, the whole wire rod drawing tool 10 is used. The height can be lowered. Thus, when the wire drawing tool 10 has a low height, for example, when a solar cell module is installed above the wire drawing tool 10, the height of the solar cell module from the roof material 2 can be reduced. There is.

  Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to the above-described embodiments, and various improvements and design changes can be made without departing from the scope of the present invention. It is. In the following, parts having the same configuration are denoted by the same reference numerals, and detailed description thereof is omitted.

  For example, in the above embodiment, the main body member 12 having one protrusion 12f is shown. However, the present invention is not limited to this. As shown in FIG. 7A, two protrusions 12f are provided. You may make it have, and as shown in FIG.7 (b), you may make it have three projection parts 12f. More specifically, in FIG. 7A, the protrusions 12f are protruded from both sides in the width direction on the inner peripheral surface of the opening 12d. Moreover, in FIG.7 (b), the projection part 12f is protruded from the ridge side in the inner peripheral surface of the opening part 12d, and the both sides of the width direction, respectively. Thus, even if it has two or more projection parts 12f, there can exist an effect similar to the above. The only difference between the main body member 12 of FIG. 7 and the main body member 12 of the above-described embodiment is the number and position of the protrusions 12f.

  In the above embodiment, the protrusion 12f of the main body member 12 is projected at the upper end edge of the opening 12d. However, the present invention is not limited to this, and the protrusion is formed in the middle of the opening 12d in the vertical direction. The part 12f may be protruded.

  In the above embodiment, the roof material 2 is slate. However, the present invention is not limited to this, and may be a sheet metal roof material, asphalt single, or tile.
