Description

The present invention relates to a component connector used to connect various components, including single-tube pipes, to panel components that make up suspended scaffolding or side protection materials.

For construction work at high altitudes, suspended scaffolding made of multiple connected panel members is used. The applicant of this application has previously obtained a patent for one such panel member (Patent Document 1).

As shown in FIG. 11, this panel member A is made up of two elongated materials B arranged in parallel with a gap between them, two connecting pipes (frame pipes) C provided between the two elongated materials B, and a reinforcing material D installed between the two elongated materials B and the two connecting pipes, on the upper surface of a peripheral frame on which a rectangular panel portion E (e.g., a metal plate, plywood, expanded metal, or other panel portion) is provided.

The panel member A shown in FIG. 11 has, as reinforcement materials D, vertical reinforcement materials D1 parallel to the two elongated members B, and horizontal reinforcement materials D2 arranged perpendicular to the vertical reinforcement materials D1. Multiple horizontal reinforcement materials D2 are provided at intervals in the longitudinal direction of the vertical reinforcement materials D1. Multiple hanging rings K are attached to the vertical reinforcement materials D1 so that they can be pulled upward from hanging ring holes E1 formed in the panel portion E.

There is a gap F between the horizontal reinforcement D2 at both ends of the longitudinal direction and the frame pipe C, and a locking member G is provided between the horizontal reinforcement D2 and the frame pipe C to connect them. This panel member A comes in sizes of 2000 mm long x 660 mm wide, 3000 mm long x 660 mm wide, 3850 mm long x 660 mm wide, etc.

As shown in Figure 12, the suspended scaffolding is formed by connecting the panel members A vertically and horizontally using joints J (see Figure 11) or swivel clamps (not shown), and then suspending them from a suspension chain I suspended from a platform (main girder) H of an elevated road or railway bridge, etc.

Patent No. 2647801

The panel member A is used as the scaffold panel A1 that constitutes the suspended scaffold, and also as the side protection material A2 that is erected on the side of the scaffold panel A1. Conventionally, when installing the side protection material A2 on the panel part E of the scaffold panel A1, a single pipe for attaching the side protection material is installed on the upper surface of the panel part E using a hanging ring K, and the single pipe and the frame pipe C of the side protection material A2 are bound together with annealed iron wire.

However, installing the single-tube pipes on the top surface of panel section E was time-consuming. In addition, annealed iron wire corrodes over time and is difficult to maintain its strength, so regular inspections were required, resulting in a significant workload.

When installing the side protection material A2, it is necessary to support the side protection material A2 with a bracing pipe Q. Conventionally, when installing the bracing pipe Q on the side protection material A2, as shown in FIG. 13, a single pipe (vertical pipe) N arranged vertically is connected to the upper and lower frame pipes C of the side protection material A2 with an orthogonal clamp Ra, and then a single pipe (horizontal pipe) O arranged perpendicular to the vertical pipe N is connected to the vertical pipe N with another orthogonal clamp Rb, and the bracing pipe Q is connected to the horizontal pipe O with another orthogonal clamp Rc.

However, with this method, the distance between the two support points of the vertical pipe N is as wide as the distance between the upper and lower frame pipes C, which increases the bending moment and can result in insufficient strength.

In this case, possible countermeasures would be to provide an additional support point midway between the upper and lower support points, or to increase the number of support pipes Q. However, the former method is not feasible due to a structural problem with the scaffolding panel A1, which means that a clamp cannot be attached to the midpoint of the side protection material A2. On the other hand, the latter method is feasible, but would create new issues such as increased workload and higher costs as the number of support pipes Q increases.

Each of these issues can be resolved by making it possible to attach a pipe member (for example, a single-tube pipe) to the panel portion E of the panel member (scaffolding panel A1 or side protection material A2), but until now, no technology has been proposed that would allow a single-tube pipe to be attached to the panel portion E.

The present invention was made in consideration of these circumstances, and its problem to be solved is to provide a component connector that can attach a pipe component to the panel portion of a panel component.

The member connector of the present invention comprises a base portion that is attached to the panel portion of the panel member and a base portion fixing device that holds the base portion, and a clamp that holds the tube member is provided on the base portion.

The base portion can also be provided with a hanging device having a ring member. The hanging device or clamp can be removably attached to the base portion. The base portion can also be provided with a through hole through which the hanging ring of the scaffold panel can be exposed.

The base fixing device can be a U-bolt with a curved portion and a rod-shaped portion. In this case, the base can be provided with an insertion hole through which the rod-shaped portion of the U-bolt can be inserted.

According to the present invention, a pipe member can be attached to the panel portion of the panel member, which helps to eliminate the various inconveniences mentioned above.

(Embodiment)
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the drawings. A member connector 10 of the present invention is used by attaching it to a panel portion E of a panel member A (see FIG. 11).

First, we will explain panel member A. Panel member A shown in Figure 11 is a rectangular panel portion (e.g., a metal plate, plywood, expanded metal, or other panel portion) E that is fixed to the upper surface of a peripheral frame that includes two elongated members B, two connecting pipes (frame pipes) C, and a reinforcing member D.

The panel member A shown in FIG. 11 has, as reinforcement materials D, vertical reinforcement materials D1 parallel to the two elongated members B, and horizontal reinforcement materials D2 arranged perpendicular to the vertical reinforcement materials D1. Multiple horizontal reinforcement materials D2 are provided at intervals in the longitudinal direction of the vertical reinforcement materials D1. Multiple hanging rings K are attached to the vertical reinforcement materials D1 so that they can be pulled upward from hanging ring holes E1 formed in the panel portion E.

There is a gap F between the horizontal reinforcement D2 at both ends of the longitudinal direction and the frame pipe C, and a locking member G is provided between the horizontal reinforcement D2 and the frame pipe C to connect them. This panel member A comes in sizes of 2000 mm long x 660 mm wide, 3000 mm long x 660 mm wide, 3850 mm long x 660 mm wide, etc.

As shown in FIG. 12, the panel members A can be hung from suspension chains I suspended from a platform (main girder) H of an elevated road or railway bridge, etc., and connected vertically and horizontally to form a suspended scaffolding.

Next, an example of the member connector 10 of the present invention will be described. The member connector 10 of the present invention is used by attaching it to the panel portion E of the panel member A.

As an example, the member connector 10 shown in FIG. 1 has a base portion 11 that is attached to the panel portion E. In this embodiment, the base portion 11 is composed of a rectangular plate-shaped member (plate). In this embodiment, the base portion 11 is, as an example, a steel plate (SS flat steel) that is 150 mm long x 100 mm wide x 6 mm thick, but the size and material of the base portion 11 may be other than this.

Two mounting parts 12 are provided on the surface of the base part 11 that is fitted to the panel part E (hereinafter referred to as the "fitting surface") 11a and the opposite surface (hereinafter referred to as the "mounting surface") 11b, spaced apart in the longitudinal direction of the base part 11.

Of the two mounting parts 12, one mounting part (first mounting part) 12 is for mounting a sling 13 (hereafter referred to as the "sling mounting part") 12a, and the other mounting part (second mounting part) 12 is for mounting a clamp 14 (hereafter referred to as the "clamp mounting part") 12b.

In this embodiment, the sling attachment part 12a and the clamp attachment part 12b are formed by welding a nut that is partially embedded in the attachment surface 11b of the base part 11. Here, the nut used for the sling attachment part 12a is larger (higher) than the nut used for the clamp attachment part 12b, but both attachment parts 12 can be the same height. In some cases, the nut used for the clamp attachment part 12b can be larger than the nut used for the sling attachment part 12a.

As shown in FIG. 2(a), the sling attachment portion 12a is provided with a sling 13 for fastening various members such as a chain I (FIG. 12) in place of a sling ring K. In this embodiment, the sling 13 is a sling cart that has a shaft 13a that is screwed into a nut hole in the sling attachment portion 12a and a ring-shaped member 13b rotatably connected to the shaft 13a. The sling 13 may be something other than a sling cart as long as it can achieve the intended purpose.

In this embodiment, the sling 13 is removably attached to the sling attachment portion 12a. The sling 13 can also be fixed to the sling attachment portion 12a so that it cannot be removed from the sling attachment portion 12a.

As shown in FIG. 2(b), the clamp attachment portion 12b is provided with a clamp 14 that holds the single-tube pipe. In this embodiment, the clamp 14 is a shaft clamp that includes a shaft portion 14a that is screwed into a nut hole in the clamp attachment portion 12b and a single clamp 14b that is provided on one end side of the shaft portion 14a.

In this embodiment, the single clamp 14b has a fixed part 14d with a recess 14c in which the single pipe fits, and a movable part 14e that holds the single pipe in the recess 14c. A screw rod with a nut 14f is provided on the free end side of the fixed part 14d, and a locking groove 14g in which the screw rod with a nut 14f fits is provided on the free end side of the movable part 14e.

In addition, the single clamp 14b may have a screw rod with a nut 14f on the free end side of the movable part 14e and a locking groove 14g on the free end side of the fixed part into which the screw rod with a nut 14f fits. The single clamp 14b may have a configuration other than those described above as long as it can achieve the intended purpose.

In this embodiment, the clamp 14 is removably attached to the clamp attachment portion 12b. The clamp 14 can also be fixed to the clamp attachment portion 12b so that it cannot be removed from the clamp attachment portion 12b.

Between the hanging tool attachment portion 12a and the clamp attachment portion 12b of the base portion 11, near the hanging tool attachment portion 12a, there is provided a through hole 15 through which a part of the hanging ring K of the panel member A is exposed (FIGS. 1 and 2(c)). In this embodiment, the through hole 15 is an elongated hole that is long in the short direction of the base portion 11, but the shape of the through hole 15 may be other than this.

At both longitudinal outer positions of the through hole 15 in the base portion 11, there are insertion holes 16 through which the rod-shaped portion 17b of the base portion fixing device 17 described later is inserted.

Between the clamp attachment portion 12b of the base portion 11 and the through hole 15, a baseboard placement space 18 is provided for placing a baseboard (not shown). The baseboard is a member used to close the gap F between the reinforcing material D of the side protection material A2 and the frame pipe C when, for example, a side protection material A2 is erected above the scaffold panel A1 in FIG. 5.

The base portion 11 in this embodiment is fixed to the panel portion E of the panel member A by a base portion fixing device 17. In this embodiment, a U-bolt with an arc-shaped curved portion 17a and two rod-shaped portions 17b is used as the base portion fixing device 17. Male threads are formed on the two rod-shaped portions 17b.

When a U-bolt is used as the base fixing device 17, both rod-shaped portions 17b of the U-bolt are inserted into both insertion holes 16 from the back side of the panel portion E, and nuts 17c are fastened to the portions of both rod-shaped portions 17b that protrude above the top surface of the panel portion E.

As shown in FIG. 11, in this embodiment, the panel member A has a vertical reinforcement D1 on the back side of the panel portion E. Therefore, when a U-bolt is used as the base portion fixing device 17, the vertical reinforcement D1 is placed between the two rod-shaped portions 17b, in other words, the U-bolt is placed over the vertical reinforcement D1 from below.

The base portion 11 can be attached to the panel portion E before the suspended scaffolding is installed, or it can be attached to the panel portion E after the suspended scaffolding is installed. If the base portion 11 is attached after the suspended scaffolding is installed, it is difficult to insert the base portion 11 into the insertion hole 16 from the back side of the panel portion E, so a jig X as shown in FIG. 3(a) can be used.

3(a) is a rod-shaped member having a connecting portion X1 at one end for connecting to a U-bolt, and a thin plate-shaped knob portion X2 at the other end. When using this jig X, the base portion 11 can be held by the U-bolt by following the steps (1) to (6) below.
(1) As shown in FIG. 3( a ), a U-bolt with its rod-shaped portion 17 b connected to the connecting portion X1 of the jig X is laid horizontally, and the other rod-shaped portion 17 b of the U-bolt is inserted into the gap of the hanging ring hole E1 of the panel portion E.
(2) After the other rod-shaped portion 17b of the U-bolt is inserted, the jig X is raised vertically as shown in FIG. 3(b) and then rotated horizontally by 180 degrees.
(3) The horizontally rotated jig X is lifted upward as shown in FIG. 3( c ), and both rod-shaped portions 17 b of the U-bolt are pulled up to the upper surface side of the panel portion E through the hanging ring holes E 1 of the panel portion E.
(4) When both rod-shaped portions 17b protrude above the upper surface of panel portion E, remove jig X from the U-bolt as shown in Fig. 3(d). At this time, when removing jig X from the U-bolt, temporarily fasten the U-bolt as necessary to prevent the U-bolt from falling.
(5) After removing the jig X from the U-bolt, the base portion 11 is placed on the upper surface of the panel portion E so that the portions of both rod-shaped portions 17b that protrude above the upper surface of the panel portion E pass through the insertion holes 16 of the base portion 11, as shown in Figure 3 (e).
(6) After placing the base portion 11 on the upper surface of the panel portion E, nuts 17c are tightened to both rod-shaped portions 17b of the U-bolt from above the base portion 11 as shown in Figure 3 (f) to fix the base portion 11 to the panel portion E.

When a U-bolt is used as the base fixing device 17 and the reinforcing material D is placed over it from below, the base 11 is more likely to be stabilized. In addition, compared to when the reinforcing material D is not placed over it from below, the strength of the base 11 itself is more easily ensured. However, the base fixing device 17 shown here is only an example, and the base fixing device 17 may be something other than a U-bolt.

When a U-bolt is used as the base fixing device 17, a fall prevention device such as a wire can be attached to the nut 17c. The same applies when using something other than a U-bolt as the base fixing device 17.

The member connector 10 of the above embodiment is an example, and the member connector 10 of the present invention is not limited to the configuration of the above embodiment. The member connector 10 of the present invention can be modified, such as by replacing, adding, or omitting, the configuration as appropriate, to the extent that the intended purpose can be achieved.

For example, as a modification of the member connector 10, the base portion 11 can be constructed using a channel steel as shown in FIG. 4 instead of the SS flat steel of the above embodiment. In this case, commercially available channel steel (channel steel material) or press-formed steel can be used. By constructing the base portion 11 from a steel material with protrusions (ribs) 11c on both ends in the width direction, like a channel steel, it is expected that the strength, specifically the bending stress, will be improved.

(Example of use 1)
Next, a first use example of the member connector of the present invention will be described with reference to Fig. 5 and Fig. 6(a). This use example is an example in which side protection material A2 is erected on a scaffold panel A1 using the member connector 10 described in the above embodiment. In this use example, the panel member A in Fig. 11 is used as the scaffold panel A1 and the side protection material A2.

(1) As shown in Fig. 5, a member connector 10 is attached to a panel portion E of a scaffolding panel A1 constituting a suspended scaffolding. The member connector 10 is attached to a plurality of scaffolding panels A1.
(2) Next, the side protective materials A2 connected horizontally are arranged vertically so as to span the multiple clamps 14 of the component connectors 10, and the frame pipes C of the side protective materials A2 are held by the clamps 14 of each component connector 10 to erect the side protective materials A2.
(3) After the side protective material A2 is erected in (2) above, a single-tube pipe is placed on the back side of the side protective material A2 as a backing pipe Q1, and one end (upper end) of the pipe is connected to the upper frame pipe C of the side protective material A2 with an orthogonal clamp R1, and the other end (lower end) of the pipe is connected to one of the frame pipes C of the scaffolding panel A1 with an orthogonal clamp R2.

Each component connected in the above-mentioned manner has a connection structure as shown in Figure 6(a). Figure 6(a) is an explanatory diagram of the connection point between the scaffolding panel A1 and the side protection material A2 connected in the above-mentioned manner. As shown in this figure, the connection point between the scaffolding panel A1 and the side protection material A2 is such that a component connector 10 is attached to the panel part E of the scaffolding panel A1 that constitutes the suspended scaffolding, and the lower frame pipe C of the side protection material A2 is held by the clamp 14 of the component connector 10.

The side protection material A2, which is held upright by the clamps 14 of the component connectors 10, is supported by a bracing pipe Q1. One end (upper end) of the bracing pipe Q1 is connected to the upper frame pipe C of the side protection material A2 by an orthogonal clamp R1, and the other end (lower end) is connected to one of the frame pipes C of the scaffolding panel A1 by an orthogonal clamp R2.

(Example of use 2)
A second use example of the member connector 10 of the present invention will be described with reference to Fig. 5 and Fig. 6(b) and (c). This use example is an example in which the member connector 10 described in the above embodiment is used to attach a middle scaffold S to a side protection material A2 erected on a scaffold panel A1. As in use example 1, in this use example, the panel member A in Fig. 11 is used as the scaffold panel A1 and the side protection material A2.

(1) As shown in Fig. 5, the member connectors 10 are attached to the panel portion E of the side protection material A2 erected on the scaffold panel A1. The member connectors 10 are attached to a plurality of panel portions E. In this example of use, the member connectors 10 are attached separately to the upper and lower stages.
(2) A single pipe (hereinafter referred to as the "upper auxiliary pipe") T1 is positioned so as to span the clamps 14 of the multiple component connectors 10 attached to the upper tier in (1), and the upper auxiliary pipe T1 is held by the multiple clamps 14 of the multiple component connectors 10 attached to the upper tier.
(3) Similarly, a single-tube pipe (hereinafter referred to as the "lower auxiliary pipe") T2 is positioned so as to span the clamps 14 of the multiple component connectors 10 attached to the lower tier in (1), and the lower auxiliary pipe T2 is held by the multiple clamps 14 of the multiple component connectors 10 attached to the lower tier.
(4) A single pipe (hereinafter referred to as a "vertical auxiliary pipe") T3, which is oriented perpendicular (vertical) to the upper auxiliary pipe T1 and the lower auxiliary pipe T2, is connected to the upper auxiliary pipe T1 and the lower auxiliary pipe T2, which have been attached in the above steps (1) to (3), using an orthogonal clamp R3. A plurality of vertical auxiliary pipes T3 are connected at intervals in the longitudinal direction of the upper auxiliary pipe T1 and the lower auxiliary pipe T2.
(5) A corbel frame (bracket) U is connected to each vertical auxiliary pipe T3 attached in (4) above, and a middle scaffold S is attached so as to straddle adjacent corbel frames U. The corbel frames U and middle scaffold S can be existing or new ones.

The components connected in the above-mentioned procedure have a connection structure as shown in Figures 6(b) and 6(c). Figure 6(b) is an explanatory diagram of the connection points of the upper auxiliary pipe T1 and the lower auxiliary pipe T2 connected to the side protection material A2 in the above-mentioned procedure.

As shown in this figure, the base parts 11 of the member connectors 10 are attached to the panel part E of the side protection material A2 with a gap between them, and the upper auxiliary pipe T1 is held by the clamp 14 of the upper member connector 10, and the lower auxiliary pipe T2 is held by the clamp 14 of the lower member connector 10.

Figure 6 (c) is an explanatory diagram of the connection points between the upper auxiliary pipe T1 and the lower auxiliary pipe T2 and the vertical auxiliary pipe T3 installed in the above procedure, as well as the connection points between the vertical auxiliary pipe T3 and the corbel frame U.

As shown in this figure, a vertical auxiliary pipe T3 is placed in front of the upper auxiliary pipe T1 and the lower auxiliary pipe T2 installed in the above procedure, and is connected to the upper auxiliary pipe T1 and the lower auxiliary pipe T2 with an orthogonal clamp R3. Multiple vertical auxiliary pipes T3 are attached at intervals in the arrangement direction of the side protection material A2.

As mentioned above, a corbel frame U is connected to each vertical auxiliary pipe T3, which is connected to the upper auxiliary pipe T1 and the lower auxiliary pipe T2, and a middle scaffold S is installed on the top surface of adjacent corbel frames U so as to span multiple corbel frames U.

(Example 3)
A third use example of the member connector 10 of the present invention will be described with reference to Fig. 7 and Fig. 8(a) and (b). This use example is an example in which the member connector 10 described in the above embodiment is used to attach a retaining pipe Q2 to a side protection material A2. As in use examples 1 and 2, this use example also uses the panel member A of Fig. 11 as the scaffold panel A1 and the side protection material A2.

(1) As shown in Fig. 7, a member connector 10 is attached to a panel portion E of a scaffolding panel A1. The member connector 10 is attached to a plurality of scaffolding panels A1.
(2) A single pipe (hereinafter referred to as the "scaffolding panel side auxiliary pipe") T4 is positioned so as to span the clamps 14 of the multiple component connectors 10 installed in (1) above, and the scaffolding panel side auxiliary pipe T4 is held by the multiple clamps 14 of the multiple component connectors 10.
(3) Similarly, the member connectors 10 are attached to the panel parts E of the side protection materials A2 erected on the scaffold panel A1. The member connectors 10 are attached to the multiple side protection materials A2.
(4) A single pipe (hereinafter referred to as the "protective material side auxiliary pipe") T5 is positioned so as to span the clamps 14 of the multiple component connectors 10 installed in (3) above, and the protective material side auxiliary pipe T5 is held by the multiple clamps 14 of the multiple component connectors 10.
(5) A support pipe Q2 is arranged so as to straddle both the scaffolding panel side auxiliary pipe T4 attached in the steps (1) and (2) above and the protective material side auxiliary pipe T5 attached in the steps (3) and (4) above, and a position near the lower end of the support pipe Q2 is connected to the scaffolding panel side auxiliary pipe T4 with an orthogonal clamp R4, and a position near the upper end of the support pipe Q2 is connected to the protective material side auxiliary pipe T5 with another orthogonal clamp R5. A plurality of support pipes Q2 are attached at intervals in the longitudinal direction of the scaffolding panel side auxiliary pipe T4 and the protective material side auxiliary pipe T5.

When connecting the support pipe Q2 using the component connector 10, there is no need to connect the vertical pipe N to the frame pipes C above and below the side protection material A2, nor is there a need to connect the horizontal pipe O to the vertical pipe N, as in the conventional case (Figure 13), which improves work efficiency.

Another advantage is that it is less likely to cause problems with insufficient strength due to the wide distance between the support points of the vertical pipes N, which was a concern with the conventional method.

The components connected in the above-mentioned manner have a connection structure as shown in Figures 8(a)(b) and 9(a)(b). Figure 8(a) is an explanatory diagram of the connection point between the scaffolding panel A1 and the scaffolding panel side auxiliary pipe T4 connected in the above-mentioned manner.

As shown in this figure, the base portion 11 of the member connector 10 is attached to the panel portion E of the scaffolding panel A1, and the auxiliary pipe T4 on the scaffolding panel side is held by the clamp 14 of the member connector 10.

Figure 8 (b) is an explanatory diagram of the connection point between the side protection material A2 and the protection material side auxiliary pipe T5 connected in the above-mentioned procedure. As shown in this figure, the base part 11 of the member connector 10 is attached to the panel part E of the side protection material A2, and the protection material side auxiliary pipe T5 is held by the clamp 14 of the member connector 10.

Figure 9 (a) is an explanatory diagram of the connection point between the scaffolding panel side auxiliary pipe T4 and the support pipe Q2, which were connected to the scaffolding panel A1 in the above procedure. As shown in this figure, the support pipe Q2 is arranged on the outside of the scaffolding panel side auxiliary pipe T4, and the lower end side of the support pipe Q2 is connected to the scaffolding panel side auxiliary pipe T4 by an orthogonal clamp R4.

Figure 9 (b) is an explanatory diagram of the connection point between the protective material side auxiliary pipe T5 and the retaining pipe Q2, which were connected to the side protective material A2 in the above procedure. As shown in this figure, the retaining pipe Q2 is arranged on the outside of the protective material side auxiliary pipe T5, and the upper end side of the retaining pipe Q2 is connected to the protective material side auxiliary pipe T5 by the orthogonal clamp R5.

In the third use example, one end (upper end) of the support pipe Q2 is connected to the protective material side auxiliary pipe T5 and the other end (lower end) is connected to the scaffold panel side auxiliary pipe T4. However, if there is a structure to which the support pipe Q2 is connected, one end of the support pipe Q2 can be connected to the protective material side auxiliary pipe T5 and the other end to the structure. In this case, the support pipe Q2 does not need to be installed at an angle, and can be installed (for example, horizontally) toward the connection position of the structure.

(Application example)
Finally, an example of installing an emergency door V using side protection material A2 erected on a scaffold panel A1 will be described with reference to Figures 10(a) and 10(b). As in Examples 1 to 3, in this application example, the panel member A in Figure 11 is used as the scaffold panel A1 and the side protection material A2.

The emergency door V is a door for opening and closing an emergency exit formed between side protective materials A2. As an example, the emergency door V shown in FIG. 10(a) is a vertically rectangular member. Finger hooks V1 are provided on the leading and trailing ends of the emergency door V for hooking fingers when opening and closing.

A hanging device V2 that suspends the emergency door V is attached to the upper end of the front and rear ends of the emergency door V. The hanging device V2 fits within a rail W provided above the emergency door V, and the emergency door V slides as the hanging device V2 slides within the rail W.

A door support Y is provided on the rear side of the emergency door V in the opening direction to prevent the emergency door V from rattling when open. As an example, the door support Y shown in FIG. 10(b) includes a clamp Y1 that holds the frame pipe C and a door support body Y2 that fits the lower end of the rear end of the emergency door V. The clamp Y1 and the door support body Y2 are connected by a connector (not shown).

The door receiving body Y2 has an upright portion Y3 facing the front and rear in the thickness direction of the emergency door V, a bottom portion Y4 below both upright surfaces Y3, and a retaining portion Y5 provided at the end of both upright portions Y3 on the forward side in the opening direction of the emergency door V.

Of the two upright portions Y3 of the door receiving body Y2, an opening Y6 that does not have a structure equivalent to the retaining portion Y5 is formed at the end on the rear side in the opening direction of the emergency door V. In addition, an upper opening Y7 is engaged at the upper end side of the two upright portions Y3 (above the bottom portion Y4).

A clamp Y1 is connected to one side of the standing portion Y3. The clamp Y1 can be an existing or new one.

In the example shown in FIG. 10(a), the door receiving device Y is connected to the frame pipe C of the side protection material A2 installed on the forward side of the opening direction of the emergency door V by the clamp Y1 so that the upper opening Y7 faces upward.

The door support Y installed in this position fits over the lower end of the emergency door V when it is opened in an emergency, preventing the open door from rattling in the front-to-back direction (thickness direction).

The above-mentioned use examples and application examples are merely examples, and the component connector 10 of the present invention can be used in other ways. Furthermore, the procedures in each use example and application example are also merely examples, and the procedures can be changed as appropriate depending on the environment and circumstances of the construction site (for example, the time of day, area, weather, etc.).

The component connector 10 of the present invention can be used to attach a single-tube pipe to the panel portion of various panel components, and is particularly suitable for use when attaching a single-tube pipe to the panel portion E of the panel component A shown in Figure 11.
