Description

  The present invention relates to a call connection jig and a call connection method for connecting a call to an eaves, and more particularly to a call connection for connecting a call to an eaves already attached to a building body. The present invention relates to a jig and a call connection method.

  The eaves, eaves, and lanterns are well-known as eaves installed in the building itself. The installation procedure for these fences is to attach the eaves to the eaves of the building body, attach the eaves along the outer wall of the building body, and then connect the call that was previously attached to the eaves to the eaves. (For example, patent document 1). The above procedure is employed, for example, in the case where the building materials around the eaves including the eaves are shipped from the factory in an appropriately unitized state for the purpose of reducing the amount of work at the construction site.

JP-A-6-307036

  However, since the call is located below the eaves, it is difficult to connect the call and eaves from the inside of the building (inside the room) after the eaves are attached to the main body. This is particularly difficult when the overhang (overhang length) is long. On the other hand, when connecting the call and eaves from the outside of the building body (outside of the building), adjacent buildings such as densely populated houses are close to each other and it is difficult to secure a working space outside the building body. The above connection work may be difficult in an environment.

  As described above, when connecting the eaves to the eaves after the eaves are attached to the building body, the call may not be properly connected to the eaves. This will lead to deterioration of construction quality.

  The present invention has been made in view of the above-described problems, and its purpose is to call the door and the eaves when the eaves are attached to the building body from the inside of the building body. The proper connection is between the eaves and the eaves.

According to the call connection jig of the present invention, (A) a support base for supporting a call connected to the eaves at a position below the eaves attached to the building body, B) When the upper end of the call face is facing the fitting hole formed in the eaves bowl, a press part that presses the eave cup from above; and (C) the press part in the vertical direction; A distance adjusting mechanism for reducing the distance between the supporting base and (D) the distance adjusting mechanism being driven by a user while the pressing portion is pressing the eaves; This is solved by including an operated portion that causes the distance adjusting mechanism to reduce the distance.
By using the call connection jig of the present invention, it is possible to support the call in a state where the upper end of the call faces the fitting hole formed in the eaves. And if the to-be-operated part is operated in this state, the distance between the holding part that holds down the eaves from above and the support that supports the caller will shrink. That is, the gap between the eaves and the call is narrowed, and the upper end of the call is fitted into the fitting hole of the eaves and the call is finally moved to the eaves. Will be connected to. As a result, when the eaves are attached to the main body of the building, the connection work between the call and the eaves is performed from the inside of the main body of the building, or on the roof of the building main body where the eaves are extended Even when the connection work is performed, the call can be connected to the eaves well.

In the above-mentioned jig for connecting a call, the jig further includes a facing portion facing the support base in the vertical direction, and the distance adjusting mechanism is provided with the pressing portion at a lower end, and with respect to the facing portion. And having a penetrating body penetrating the facing portion, which is relatively movable along the vertical direction, and the operated portion is operated by the user while the pressing portion presses the eaves. Thus, the distance may be shortened by moving the penetrator relative to the facing portion in the vertical direction so that the pressing portion approaches the support base.
If it is a jig of such a configuration, with a relatively simple configuration, the gap between the eaves and the caller is narrowed and the upper end of the caller is fitted into the fitting hole of the eaves, that is, It becomes possible to connect a call.

Further, in the above-mentioned call connection jig, a support base fixing portion in which the support base is fixed to an upper end surface, and a connecting portion that crosses both the facing portion and the support base fixing portion and connects the both. The support fixing portion, the facing portion, and the connecting portion are integrated, and the distance adjusting mechanism is configured such that the operated portion is pressed while the pressing portion is pressing the eaves. By operating by the user, the penetrating body is moved relative to the facing portion so that the integrated support fixing portion, the facing portion, and the connecting portion rise relative to the pressing portion. The distance may be shortened by relative movement along the vertical direction.
In such a case, it is possible to reliably reduce the distance between the pressing portion and the support base by the relative movement of the penetrating body.

Further, in the above-mentioned call connection jig, the connecting portion connects one end portion of the facing portion and one end portion of the support base fixing portion, and the operated portion is the other end portion of the facing portion. It is good also as being a lever attached to.
If the jig has such a configuration, it is possible to operate the operated portion while supporting the caller at a lower position of the eaves (that is, an operation for narrowing the interval between the eaves and the caller). It becomes possible to perform well from the inside.

Further, in the above-mentioned call connection jig, the eaves rod is provided with a free drain, and the upper portion of the free drain is formed upright from the periphery of the fitting hole, The pressing portion may be a frame body that presses the eaves from above while surrounding the upper portion of the free drain when the upper end portion is fitted into the fitting hole.
With the jig having such a configuration, when the caller is connected to the eaves, it is possible to avoid the pressing portion from interfering with the free drain, so that the connection work is performed smoothly.

Further, a call connecting method for connecting a call to an eaves already attached to a building body, wherein (A) the call is supported when the call is arranged at a position below the eaves. A support base, a presser part that presses down the eaves, a distance adjustment mechanism that reduces a distance between the presser part and the support base in the vertical direction, and the distance adjustment mechanism that is operated by a user to drive the distance adjustment mechanism And an operated portion that causes the distance adjustment mechanism to reduce the distance; and supporting the call on the support base of the call connection jig, and (B) the upper end of the call is the Adjusting the position of the caller connection jig in a state where the caller is supported by the support base so as to face the fitting hole formed in the eaves, and (C) the upper end portion is When in the state facing the fitting hole, Pressing the eaves from above, and (D) operating the operated portion to reduce the distance by the distance adjusting mechanism while the holding portion is holding the eaves. A call connection method that includes fitting the upper end portion into a fitting hole is also feasible.
With this call connection method, it is possible to support the call with the upper end of the call facing the fitting hole of the eaves, and operate the operated part under such a state. As a result, the distance between the eaves and the call is narrowed, and eventually the call is connected to the eaves. As a result, when the eaves are attached to the main body of the building, the connection work between the call and the eaves is performed from the inside of the main body of the building, or on the roof of the building main body where the eaves are extended Even when the connection work is performed, the call can be connected to the eaves well.

  According to the jig for connecting a call of the present invention, it is possible to support the call with the upper end of the call facing the fitting hole of the eaves. When the operated part is operated in such a state, the distance between the holding part holding the eaves from above and the support stand supporting the call, that is, the distance between the eaves and the call is gradually reduced. The upper end portion of the call is fitted into the fitting hole of the eaves and finally the call is connected to the eaves. With this function, when the eaves are attached to the main body of the building, the connection work between the door and the eaves is performed from the inside of the building, or the roof of the main body of the building where the eaves are extended (the overhang length) Even when the above connection work is performed, the call can be connected to the eaves well.

<< Configuration and assembly procedure of bag unit 1 of this embodiment >>
In describing the callee connection method according to the present embodiment, the configuration and assembly procedure of the bag unit 1 assembled using the method will be outlined with reference to FIGS. FIG. 1 is a cross-sectional view of the heel unit 1. FIG. 2 is an exploded perspective view of the saddle unit 1. 3 to 5 are schematic views showing an assembling procedure of the saddle unit 1. 3 to 5, the vertical direction is indicated by arrows.

  As shown in FIG. 1, the bag unit 1 includes an eaves wall 2, a wall 3, and a call bar 4, and is configured by assembling them. The eaves bowl 2 is a sheet metal member that is bent into a substantially U shape in a side view. The eaves rod 2 extends along the eaves 5 of the building body H, and is suspended and fixed via an eaves rod suspension 6 attached to the front surface 5a of the eaves. The eaves 3 are pipe members that extend in the vertical direction along the outer wall 7 of the building body H, and are fitted and held in the eaves holder 8 attached to the outer wall 7. In addition, the building main body H means things other than the fence unit 1 among the structural elements of a building.

  The call shaft 4 is a pipe member that is positioned below the eaves cage 2 and connects the eaves cage 2 and the upper end of the cage 3. As shown in FIG. 1, the call 4 extends somewhat in the vertical direction and then bends at a substantially right angle, then extends in a direction intersecting the eaves 2 and then bends again at a substantially right angle and again in the vertical direction. It extends to. Further, the lower end portion of the caller 4 is connected to the upper end portion of the upper case 3 so as to be connected to the upper case 3. Furthermore, the call cup 4 is connected to the eaves bowl 2 by fitting its upper end portion into a fitting hole 2 a formed in the eave bowl 2.

More specifically, the eaves bowl 2 is provided with a free drain 9, and the free drain 9 can be divided into an upper part (hereinafter, free drain upper part 9a) and a lower part (hereinafter, free drain lower part 9b). The free drain upper portion 9a is erected from the peripheral edge of the fitting hole 2a, and the free drain lower portion 9b is formed between the free drain upper portions 9a. 2 is provided in the shape eaves 2 sandwiching the portion) (see FIG. 2).
Each of the free drain upper portion 9a and the free drain lower portion 9b has an opening, and is attached to the eaves 2 so that the opening overlaps the fitting hole 2a. In such a state, the inner diameter of the fitting hole 2 a is slightly larger than the outer diameter of the nominal hole 4. For this reason, when the upper end portion of the call shaft 4 is inserted into the free drain 9 from the free drain lower portion 9b, the upper end portion is fitted into the fitting hole 2a. It will be connected to the eaves 2.

  The assembly operation of the fence unit 1 configured as described above is performed at the construction site of the building including the fence unit 1. In particular, in the present embodiment, of the assembly work of the fence unit 1, work other than the installation work of the fence 3 is performed from the inside of the building main body H (specifically, indoors as viewed from the building under construction). Is called.

  Assembling work of the eaves unit 1 according to the present embodiment starts from attaching the eaves eaves 2 to the eaves 5 first. In detail, the eaves hook 6 is attached to the eaves front 5a in advance, and in this state, the eaves 2 is set at the front position of the eaves 5 and the eaves 2 is hung on the eaves hanger 6. Fix it. In addition, as above-mentioned, it is possible to perform the above operation | work from the inside of the building main body H. FIG. That is, as shown in FIG. 3, the operator sets the eaves rod 2 at the front position of the eaves 5 while extending his hand from the room, and hangs and fixes the eaves 2 on the eaves hanger 6.

  Next, the eaves 3 are leaned against the outer wall 7 of the building main body H, and the eaves 3 are fitted into the eaves holder 8 attached in advance to the outer wall 7. Thereby, the collar 3 is held at a predetermined position. In the present embodiment, the call bar 4 is already connected to the upper end of the bar 3 when the bar 3 is attached. That is, as shown in FIG. 4, the attaching work of the scissors 3 is performed in a state where the scissors 3 and the calling scissors 4 are integrated.

  After the installation work of the eaves 3 is completed, an operation for connecting the call 4 to the eaves 2 is performed. And in this embodiment, said connection work is performed from the inner side of the building main body H using the jig 10 for call connection mentioned later. That is, when the installation work of the cage 3 is completed, the call cage 4 comes to be positioned below the eaves cage 2. Even in such a state, the call connection jig 10 of this embodiment is used. By using it, the connection work of the call 4 and the eaves 2 can be performed satisfactorily from the inside of the building body H.

  The assembling work of the saddle unit 1 is advanced by the above procedure, and the assembling work is completed when the state shown in FIG. 5 is reached.

<< Call connection jig 10 according to this embodiment >>
Next, the call connection jig 10 according to the present embodiment will be described with reference to FIGS. FIG. 6 is an external view of the call connection jig 10 and is a side view of the call connection jig 10. FIG. 7 is a cross-sectional view of the support base 11 to be described later, and is a cross-sectional view taken along the line AA in FIG. FIG. 8 is a view showing a state in which a pressing portion 14 described later is pressing the eaves 2. FIG. 9 is an enlarged view of the outer peripheral surface of the penetrating body 19 described later.

  The call connecting jig 10 is a jig used when connecting the call 4 and the eaves 2 from the inside of the building body H. The call connection jig 10 has a substantially U-shaped external shape as shown in FIG. 6, and as a main component, a support base 11 that supports the call 4 during connection work, and a support base Supporting base fixing part 12 to which 11 is fixed, opposing part 13 that opposes the supporting base 11, pressing part 14 that presses down the eaves 2 from above during connection work, and a user (hereinafter also referred to as an operator) A lever 15 to be operated and a distance adjusting mechanism 16 for reducing the distance between the pressing portion 14 and the support base 11 in the vertical direction are provided.

  The support base 11 is located below the call connection jig 10 and supports the call 4 at a position below the eaves 2 already attached to the building body H. As shown in FIG. 7, the support base 11 has an aluminum steel plate 11a bent in a substantially U shape in front view, and a cushioning material made of urethane provided so as to cover the upper end surface of the steel plate 11a. 11b. The opening width of the support base 11 (distance between the side pieces 11 c of the support base 11) is somewhat shorter than the outer diameter of the call 4. Then, when the call 4 is placed on the support base 11, the opening width is increased and the call holder 4 is supported by the support base 11 while being held between the side pieces 11 c of the support base 11. In addition, the length of the support base 11 in this embodiment is about 265 mm.

  The support base fixing | fixed part 12 is the square steel material made from aluminum with which the support base 11 was fixed to the upper end surface. The support base fixing part 12 is somewhat longer than the support base 11, and the length in this embodiment is about 300 mm. The facing portion 13 is an aluminum square steel material that extends substantially parallel to the support base fixing portion 12 and faces the support base 11 in the vertical direction. The facing portion 13 and the support base fixing portion 12 are connected by a connecting portion 17 that intersects (substantially orthogonally) both the facing portion 13 and the support base fixing portion 12.

  More specifically, the connecting portion 17 is a square steel material made of aluminum, and connects one end portion in the longitudinal direction of the facing portion 13 and one end portion in the longitudinal direction of the support base fixing portion 12. Since the support fixing portion 12, the facing portion 13, and the connecting portion 17 are joined by welding, they are integrated. In the present embodiment, the facing portion 13 is somewhat shorter than the support base fixing portion 12. Therefore, as shown in FIG. 6, the other end in the longitudinal direction of the support base fixing portion 12 (the end opposite to the side fixed to the connecting portion 17) is outside the other end in the longitudinal direction of the facing portion 13. Is located. In addition, the length of the connecting portion 17 in this embodiment (in other words, the distance from the upper end surface of the facing portion 13 to the lower end surface of the support base fixing portion 12) is about 482 mm.

  The pressing portion 14 presses the eaves 2 from above when the upper end of the call 4 faces the fitting hole 2 a formed in the eaves 2. In the callee connection jig 10 according to the present embodiment, the pressing portion 14 is a substantially cylindrical frame. In the present embodiment, the pressing portion 14 surrounds the free drain upper portion 9a when the upper end portion of the call shaft 4 is fitted into the fitting hole 2a, and the peripheral edge of the fitting hole 2a in the eaves cage 2 The part is pressed from above (see FIG. 8).

  The lever 15 is an example of an operated portion operated by an operator, and is attached to the other end portion in the longitudinal direction of the facing portion 13 (the end portion on the opposite side to the side fixed to the connecting portion 17). . The lever 15 is operated by an operator while the pressing portion 14 presses the eaves 2, thereby driving a distance adjusting mechanism 16 to be described later and pressing the distance adjusting mechanism 16 in the vertical direction. The distance between the part 14 and the support base 11 is shortened.

  In the present embodiment, the lever 15 includes a fixed portion 15a and a movable portion 15b, and the movable portion 15b is rotatable about a rotation shaft (not shown). As a result of the rotation of the movable portion 15b being transmitted to the distance adjusting mechanism 16, the distance adjusting mechanism 16 is driven. When the operator grips the operated lever 15, the movable portion 15b rotates so as to approach the fixed portion 15a (that is, in the direction indicated by the arrow in FIG. 6). On the other hand, when the lever 15 is released from the gripping state, the movable portion 15b is biased by a biasing member (not shown) and returns to the original position (position before the lever 15 is gripped). As shown in FIG. 6, in this embodiment, a string 18 for preventing the fall is attached to the end portion of the fixing portion 15a.

  The distance adjusting mechanism 16 is for shortening the distance between the pressing portion 14 and the support base 11 in the vertical direction by using the gripping operation of the lever 15 by the operator. The distance adjusting mechanism 16 has a penetrating body 19 that penetrates the facing portion 13. The penetrating body 19 is a round steel whose upper end portion 19a is bent like a bowl, and has a pressing portion 14 at the lower end thereof as shown in FIG. Further, the penetrating body 19 is supported so as to be rotatable around its central axis and movable in the vertical direction. Note that when the penetrating body 19 moves along the vertical direction, the penetrating body 19 moves relative to the facing portion 13, the support base fixing portion 12, and the support base 11 along the vertical direction.

  Furthermore, as shown in FIG. 9, the outer peripheral surface of the penetrating body 19 has a gear forming surface 19a on which the gear 20 is formed and a smooth surface 19b on which the gear 20 is not formed. Further, the distance adjusting mechanism 16 has a lowering device (not shown) that lowers the penetrating body 19. This lowering device is interposed between the lever 15 and the penetrating body 19, and transmits the gripping operation of the lever 15 (in other words, the rotating operation of the movable portion 15 b) to the penetrating body 19 to lower the penetrating body 19. . In addition, the lowering device faces a part of the outer peripheral surface of the penetrating body 19 and engages with the gear 20 to regulate the vertical movement of the penetrating body 19 when facing the gear forming surface 19a. At the same time, the gripping operation of the lever 15 is accepted and the penetrating body 19 is lowered. On the other hand, in the state where the lowering device faces the smooth surface 19b, the penetrating body 19 is not regulated at all, and for example, the operator can freely move the penetrating body 19 up and down.

  The operation of the distance adjusting mechanism 16 having the above configuration will be described. When the distal end portion 19c of the penetrating body 19 faces the lever 15 side (the opposite side to the direction of the distal end portion 19c shown in FIG. 6), The lowering device faces the smooth surface 19b of the outer peripheral surface of the penetrating body 19, and the penetrating body 19 can move up and down without any restriction.

  On the other hand, when the tip 19c of the penetrating body 19 faces the side opposite to the lever 15 (the same side as the tip 19c shown in FIG. 6), the above-described lowering device Among the surfaces, it faces the gear forming surface 19 a and engages with the gear 20 to regulate the vertical movement of the penetrating body 19. Further, when the operator grips the lever 15 in such a state, the lowering device transmits the gripping operation to the penetrating body 19 and lowers the penetrating body 19. More specifically, the lowering device lowers the penetrating body 19 by the gear pitch of the gear 20 formed on the gear forming surface 19a in one gripping operation.

  As described above, the distance adjusting mechanism 16 can move the penetrating body 19 relative to the facing portion 13 in the vertical direction by operating the lever 15. Then, the relative movement of the penetrating body 19 with respect to the facing portion 13 reduces the distance between the pressing portion 14 and the support base 11.

  Even when the connection work between the call 4 and the eaves wall 2 is performed from the inside of the building main body H by using the call connection jig 10 having the configuration described above, the call can be satisfactorily performed. 4 can be connected to the eaves 2. Hereinafter, a call connection method using the call connection jig 10 will be described.

<< Call connection method according to this embodiment >>
A call connection method according to the present embodiment will be described with reference to FIGS. FIG. 10 is a diagram illustrating a flow of the call connection method according to the present embodiment. FIGS. 11-14 is the figure which showed the progress condition regarding the connection operation | work of the call 4 and the eaves 2, and the up-down direction is shown by the arrow in the figure.

  At the stage of employing the call connection method according to the present embodiment and starting the above connection work, the eave fence 2 and the eaves 3 are already attached to predetermined positions of the building body H, respectively. In other words, the call connection method according to the present embodiment is a method for connecting the call 4 to the eaves 2 already attached to the building body H. As described above, at the stage where the cage 3 is attached at a predetermined position, the call rod 4 is connected to the upper end portion of the cage 3 and is disposed at a position below the eaves cage 2. is there.

  In the above state, that is, when the call 4 is arranged at the lower position of the eaves 2, the call connection jig 10 of this embodiment is prepared and set at a predetermined position (S 001). . This step S001 is a step of supporting the call 4 on the support 11 provided in the call connecting jig 10. More specifically, first, the call connection jig 10 is set so that the support base 11 is positioned below the call 4. At this time, while confirming the position of the call 4 from the gap between the eaves 4 and the front surface 5a of the eaves, the positional relationship between the call 4 and the call connecting jig 10 is the relationship shown in FIG. The position of the call connection jig 10 is adjusted so that 11 is positioned so that 11 is positioned directly below the call ring 4.

  When adjusting the position of the call connection jig 10, the tip 19c of the penetrating body 19 faces the lever 15 as shown in FIG. 19 so that the penetrating body 19 can move up and down without any restriction. Further, at this time, the operator raises the penetrating body 19 to the top dead center position and holds the penetrating body 19 at the position.

  After the call connection jig 10 is set at a predetermined position and the call 4 is supported by the support base 11, the position of the call connection jig 10 in a state where the call 4 is supported by the support base 11. Are adjusted again (S002). Such readjustment is performed such that the upper end of the call 4 faces the fitting hole 2 a formed in the eaves 2. In addition, along with this adjustment, the posture of the call connection jig 10 is such that the holding portion 14 provided in the call connection jig 10 is positioned immediately above the fitting hole 2a of the eaves hook 2. Adjusted.

  Then, when the upper end portion of the call 4 faces the fitting hole 2a and the pressing portion 14 is positioned at a position immediately above the fitting hole 2a, as shown in FIG. The holding portion 14 held at the position is released, and the eaves 2 (specifically, the peripheral portion of the fitting hole 2a) is lowered by the holding portion 14 to a position where it can be pressed from above (S003). This step S003 is a step of pressing the eaves 2 from above by the pressing portion 14 when the upper end of the call 4 faces the fitting hole 2a. Further, in this state, the tip 19c of the penetrating body 19 is directed to the side opposite to the lever 15 side (that is, the lowering device described above is opposed to the gear forming surface 19a of the penetrating body 19). Therefore, the processes after this process S003 are performed in a state where the vertical movement of the penetrating body 19 is restricted.

  In addition, when switching the direction of the front-end | tip part 19c of the penetration body 19, it is desirable to adjust the height in the up-down direction of the caller connection jig 10. This is because the operator grips the lever 15 in the subsequent steps, and therefore the call connection jig 10 needs to be positioned at a height that does not interfere with the construction material.

  Thereafter, while the presser part 14 presses the eaves 2 from above, the lever 15 is operated to change the relative position of the presser part 14 with respect to the support base 11 (S004). In this step S004, the penetrating body 19 is moved relative to the facing portion 13 along the vertical direction so that the pressing portion 14 approaches the support base 11, and the distance between the pressing portion 14 and the support base 11 (FIG. 13 is a step of shrinking (indicated by symbol d in FIG. 13). By this step S004, the upper end portion of the call 4 is gradually fitted into the fitting hole 2a.

  Hereinafter, this step S004 will be described in more detail. This step S004 is performed in a state where the lowering device of the distance adjusting mechanism 16 faces the gear forming surface 19a of the penetrating body 19 as described above. When the operator performs a gripping operation of the lever 15 in this state, the distance adjusting mechanism 16 attempts to lower the pressing portion 14 using the gripping operation.

  On the other hand, since the holding | maintenance part 14 exists in the state which is pressing down the eaves rod 2, it cannot fall further from the position. For this reason, the distance adjusting mechanism 16 does not lower the penetrating body 19 including the pressing portion 14, but removes the penetrating body 19 (ie, the support base 11, the support fixing portion 12, the facing portion 13, the connecting portion 17, and the lever). 15) Raise. In other words, as can be seen from comparison with FIG. 15A and FIG. 15B, the distance adjustment mechanism 16 is integrated by the lever 15 being gripped while the pressing portion 14 is pressing the eaves 2. The penetrating body 19 is moved relative to the opposing portion 13 in the vertical direction so that the support fixing portion 12, the opposing portion 13, and the connecting portion 17 rise relative to the pressing portion 14. Shrink d. 15A and 15B are diagrams showing the positional relationship of each part of the caller connection jig 10 when the lever 15 is gripped with the presser 14 holding the eaves 2. FIG. 15A shows a state before the gripping operation, and FIG. 15B shows a state after the gripping operation.

  With the mechanism as described above, the distance d is reduced every time the gripping operation of the lever 15 is performed in this step S004. Thereby, the space | interval of the eaves bowl 2 and the call bowl 4 becomes narrow, and the upper end part of the call bowl 4 is first inserted in the free drain 9 from the free drain lower part 9b side. Then, when the gripping operation of the lever 15 is repeated, the upper end portion of the call 4 is finally fitted into the fitting hole 2a, and at this point, the call 4 is connected to the eaves 2 (See FIG. 14). Thereafter, when the call connection jig 10 is removed, the connection work between the call 4 and the eaves 2 is completed.

  The call connection method according to the present embodiment is realized by the series of steps described above. In the present embodiment, each of the steps S001 to S004 described above is executed from the inside of the building body H.

<< Effectiveness of Call Connection Jig 10 According to the Present Embodiment >>
As described above, the call connection jig 10 according to the present embodiment includes the support base 11 that supports the call bar 4 at the lower position of the eaves wall 2 attached to the building body H, and the call bar. While the upper end of 4 faces the fitting hole 2a formed in the eaves 2, the pressing part 14 that presses the eaves 2 from above, and the pressing part 14 is pressing the eaves 2 A lever 15 that is operated by the user, and a distance adjusting mechanism 16 that reduces the distance d between the pressing portion 14 and the support base 11 in the vertical direction when the lever 15 is operated.
With such a configuration, when the eaves 2 is attached to the building body H, the connection work between the call 4 and the eaves 2 is performed from the inside of the building body H, or the eaves projecting length (extension length) is long. Even when the above connection work is performed on the roof of the main body H, the call 4 can be connected to the eaves 2 well.

  That is, as explained in the section of the problem to be solved by the invention, since the call 4 is located below the eaves 2, after the eaves 2 is attached to the building main body H, from the inside of the building main body H It is difficult to connect the call 4 and eaves 2. In particular, the connection work becomes more difficult when the eaves are extended (the overhang length). On the other hand, when the above connection work is performed outside the building main body H, although the difficulty of the work itself is eliminated, for example, adjacent buildings such as densely populated houses are close and the building main body H In an environment where it is difficult to secure a work space outside, the work becomes difficult. As a result, there is a possibility that the call 4 is not properly connected to the eaves 2 and the construction quality of the building is deteriorated.

  In contrast, according to the call connection jig 10 of the present embodiment and the call connection method using the same, the upper end of the call 4 faces the fitting hole 2 a of the eaves 2. It is possible to support the call 4. When the lever 15 is operated under such a state, the distance d between the holding portion 14 holding the eaves 2 and the support base 11 supporting the call 4 is reduced. As a result, the upper end portion of the call 4 is gradually fitted into the fitting hole 2a of the eaves 2 and finally the call 4 is connected to the eaves 2.

  In the case of the call connection jig 10 configured as described above, the lever 15 is configured to be operable from the inside of the building body H, so that the call 4 and the eaves 2 are installed after the eaves 2 is attached. Even when the connection work is performed on the inside of the building main body H or on the roof of the building main body H where the eaves (extension length) is long, the connection work can be performed satisfactorily.

Moreover, in said embodiment, the jig 10 for call connection further has the opposing part 13 which opposes the support stand 11 in an up-down direction, and the distance adjustment mechanism 16 is the penetration body which has penetrated the opposing part 13 19, the penetrating body 19 is provided with a pressing portion 14 at the lower end, and is movable relative to the facing portion 13 along the vertical direction. Then, when the lever 15 is gripped with the pressing part 14 holding the eaves 2, the distance adjusting mechanism 16 moves the penetrating body 19 up and down so that the pressing part 14 approaches the support base 11. The distance d is shortened by moving relative to the facing portion 13 along the direction. With such a configuration, it is possible to connect the call 4 to the eaves 2 by reducing the distance d with a relatively simple configuration.
However, the present invention is not limited to the above configuration, and any configuration can be used without limitation as long as the distance d can be shortened by receiving the user's operation in a state where the pressing portion 14 presses the eaves 2. is there.

Moreover, in said embodiment, the support stand fixing | fixed part 12 to which the support stand 11 was fixed, the opposing part 13, the connection part 17 which cross | intersects both the opposing part 13 and the support stand fixing | fixed part 12, and connects the said both, Are integrated. Then, when the lever 15 is operated in a state where the pressing portion 14 is pressing the eaves 2, the distance adjusting mechanism 16 includes the integrated support fixing portion 12, the facing portion 13, and the connecting portion 17. The penetrating body 19 is moved relative to the opposing portion 13 along the vertical direction so as to rise relatively with respect to the pressing portion 14, thereby reducing the distance d. With such a configuration, the distance d can be reliably reduced by the relative movement of the penetrating body 19.
However, it is not limited to the above configuration, and when the lever 15 is operated in a state in which the pressing portion 14 is pressing the eaves 2, at least the support fixing portion 12 is relative to the pressing portion 14. As long as it rises automatically.

In the above embodiment, one end in the longitudinal direction of the facing portion 13 and one end in the longitudinal direction of the support base fixing portion 12 are connected by the connecting portion 17, and the lever 15 is connected to the other end in the longitudinal direction of the facing portion 13. It was decided that it was installed. With such a configuration, it is possible to favorably perform an operation for reducing the distance d from the inside of the building body H while supporting the call 4 at a position below the eaves 2. That is, considering the positional relationship between the operation position of the lever 15 and the support position of the call 4, it can be said that the shape of the call connecting jig 10 according to the present embodiment is simple but suitable.
However, the present invention is not limited to the above configuration, and the call connection is possible as long as the call 4 can be supported at the lower position of the eaves 2 and the lever 15 can be operated from the inside of the building body H. The jig 10 may have any shape.

In the above embodiment, the eaves rod 2 is provided with the free drain 9 and the upper portion (the free drain upper portion 9a) is erected from the periphery of the fitting hole 2a. On the other hand, the holding portion 14 of the caller connection jig 10 is a cylindrical frame, and surrounds the free drain upper portion 9a while the callee 4 is fitted in the fitting hole 2a. 2 (specifically, the peripheral edge portion of the fitting hole 2a) is pressed down. With such a configuration, it is possible to avoid the pressing portion 14 from interfering with the free drain 9 when the call 4 is connected to the eaves 2. Further, when the upper end portion of the call 4 is fitted into the fitting hole 2a, the pressing portion 14 reliably presses the periphery of the fitting hole 2a, so that the connection work is smoothly performed.
However, it is not limited to the above-described configuration. For example, the flexible drain 9 may not be provided in the eaves bowl 2, or the pressing portion 14 presses a portion away from the fitting hole 2a. Also good.
