Abstract

PURPOSE: To correctly and quickly stick a band-like member to a groove of a segment by supplying a band-like member in co-operation with a feed roller through a guide roller and pressing the same. CONSTITUTION: A seal material or a buffer material which is a band-like member is passed between a feed roller 1 and a guide roller 2, and guided to the lower side of a pressing roller 3. The feed roller 1 of the thus formed band-like member sticking tool k is advanced in the direction of an arrow while tracing a groove 8 or 10 of a segment 7. On the other hand, a handle 4 is pressed to press the band-like member against the groove by the pressing roller 3, so that sticking work can be performed correctly and quickly. At this time, even if a segment is curved, the feed roller 1 and the pressing roller 3 are respectively freely moved in the respective axial directions according to the curve, so that even in the above case, the band-like member can be stuck correctly. Further, slip-off when the groove is curved can be prevented by the slip-off preventing parts 11 of both end parts of the feed roller 1 and the pressing roller 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for accurately and quickly attaching a strip-shaped member to a groove. In particular, the strip-shaped member is accurately and quickly attached to a groove of a segment of the shield tunnel method. It relates to a tool for wearing.

[0002]

2. Description of the Related Art Conventionally, when a band-shaped member such as a sealing material or a cushioning material is pasted, after the sealing material or the cushioning material is pasted into the groove by hand, it is fixed by pressure bonding with a flat roller or the like. It was
Therefore, as shown in FIG. 5, it could not be accurately attached to the center of the groove and meandered, so that a sufficient contact area could not be obtained at the time of segment assembly, and thus a sufficient waterproof performance could not be obtained. Further, when a segment is assembled and pushed by a jack, a uniform reaction force is not generated, so that the segment is partially pushed, which may result in breakage of the segment.

Furthermore, since the positioning and pasting work and the crimping and fixing work are performed separately, it takes time.

[0004]

SUMMARY OF THE INVENTION The present invention has been made as a result of studies to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a sealing material and a cushioning material. It is an object of the present invention to provide a tool for accurately positioning a strip-shaped member such as the above in a groove of a segment of a shield tunnel and at the same time crimping the strip-shaped member.

[0005]

The present invention employs the following constitution in order to achieve the above object. That is, a tool for sticking the strip-shaped member in the groove of the segment, a supply roller for positioning and supplying the strip-shaped member,
A guide roller that cooperates with the supply roller to prevent the strip-shaped member from falling off from the supply roller, and a pressure roller that adheres the strip-shaped member to the groove while pressure-bonding the strip-shaped member. Further, the supply roller and the pressure roller are arranged in parallel and in the same plane to accurately trace the groove.

Further, the supply roller, the guide roller and the pressure bonding roller can move freely in their respective axial directions and can follow the curved grooves. A derailment prevention portion is provided at both ends of the supply roller and the pressure roller to prevent derailment from the groove. Here, the material of each roller may be a metal, but a lightweight and durable sealing material that is difficult to adhere to, for example, a polyamide resin is suitable.

[0007]

As shown in FIG. 2 of the belt-shaped member sticking tool K of the present invention (the guide roller and the roller shaft are omitted), the sealing material or the buffer material which is the belt-shaped member 6 is passed between the supply roller 1 and the guide roller 2. Then, as shown in FIG. 3, the pressure roller 3 is guided to the lower side. This is the strip-shaped member 6 in FIG.
Although omitted, the band-shaped member is arranged from the right side to the left side of the band-shaped member sticking tool K. Now, after being arranged as described above, the feeding roller of the belt-shaped member sticking tool K is advanced in the arrow direction (rightward direction) of FIG. If the band-shaped member is pressed and pressed into the groove by the pressing roller 3, the sticking work can be performed accurately and quickly. At this time, even if the groove of the segment is curved as shown in FIG. 4, the supply roller 1 and the pressure bonding roller 3 can move in the respective axial directions according to the curve. Can be easily and accurately applied. Further, derailment prevention portions 11 are provided at both ends of the supply roller 1 and the pressure roller 3, and particularly when the groove is curved because this portion works against the force to derail. However, it prevents the derailment.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a belt-shaped member sticking tool K of the present invention. As shown in the drawing, a supply roller 1, a guide roller 2 and a pressure bonding roller 3 made of a polyamide resin, and those on a frame 5. It consists of steel roller shafts 9a, 9b, 9c and a handle 4 for mounting.

According to the present invention, when the segment unit 7 shown in FIG. 4 (a) is assembled as shown in FIG. 4 (b) to construct a tunnel, a strip-shaped member that acts as a seal and a cushion is provided at the joint. Although it is necessary, the task is to carry out the work that was pasted by hand and pressed by the flat roller at the same time and quickly. First, a strip-shaped member having a required length is prepared, passed between the supply roller 1 and the guide roller 2, and guided to the lower side of the pressure bonding roller 3 as shown in FIG. Then, the supply roller 1 and the pressure bonding roller 3 are traced in alignment with the groove 8 or groove 10 of the segment 7 and are advanced in the arrow direction (rightward direction) of FIG.
By pressing and pressing the strip-shaped member into the groove with the pressure-bonding roller 3, the sticking work is completed. Regarding the width of the groove and the width of the roller, if the width of the roller is reduced by about 0.3 mm, it is light without rattling and the groove can be traced reliably.

Further, even if the groove of the segment is curved as shown in FIG. 4, the supply roller 1 and the pressure bonding roller 3 are allowed to float in the respective axial directions according to the curve. It is sufficient if the distance is about 5 to 6 mm. Further, if the width of the wheel slip-off preventing portion is about 3 to 5 mm on one side, its function can be sufficiently exhibited.

[0011]

As is apparent from the above description, according to the band-shaped member sticking tool of the present invention, the band-shaped member of the seal material or the cushioning material can be accurately and quickly inserted into the groove of the segment of the shield tunnel. Can be attached to.
