Abstract

PROBLEM TO BE SOLVED: To solve the problem of gradually becoming difficult to execute work as construction advances when deflection of a waterproof sheet roll is easily caused, due to becoming nervous by being troublesome, when being high in the possibility of dropping a disassembled part on a narrow scaffold of a high place of becoming an actual waterproof sheet construction site, though there is the necessity of disassembling a part of a unit, when replenishing a waterproof sheet roll, in a portable retainer of a conventional waterproof sheet roll.SOLUTION: The portable retainer of the waterproof sheet roll is provided with a column, a base fixed to both end parts of the column and a core rod having on both bases a cantilever shaft capable of journaling the waterproof sheet roll between the bases, having at least one cantilever shaft freely moving in the axial direction of the waterproof sheet roll and journaled by the two cantilever shafts, and is provided with an elastic body for always pressing the waterproof sheet roll from a side surface.

Description

  The present invention relates to a portable holder for a waterproof sheet roll used when a waterproof sheet is attached to a building body.

  In a general wooden construction method, a joist or floor is laid horizontally on a foundation, a pillar is set on it, a beam is built between the upper part of the pillar, etc. Prior to construction, a waterproof sheet is attached to the entire wall surface to prevent water leakage on the wall.

  The tarpaulin is usually provided as a roll-shaped tarpaulin roll, and when affixing it to a building, the installer holds the tarpaulin roll with one hand so that the roll axis is vertical. Roll the waterproof sheet in the extending direction, hit the pin with a needle punch with the other hand, and stick the waterproof sheet to the pillar or beam.

  However, in the above-described method, since the work is performed in an unstable posture, it is difficult to perform reliable construction. In addition, the tarpaulin roll is heavy to hold with one hand, so the range that can be constructed at one time is limited due to the physical problems of the installer, and each time it is necessary to cut the tarpaulin once and start over, work efficiency is Very bad.

  Therefore, in some cases, there is a method in which one of the contractors holds the waterproof sheet roll and the other contractors pull out and paste the waterproof sheet, but one work is performed by two contractors. Needless to say, it is inefficient.

  In view of this, Japanese Patent Application Laid-Open No. 2000-87558 and Japanese Patent Application Laid-Open No. 2005-82260 propose a waterproof sheet roll holder that allows a waterproof sheet roll to be installed at an arbitrary position and pulled out. However, in any embodiment, when the tarpaulin roll is refilled, a part of the unit must be disassembled once. Actual tarpaulin construction is mostly carried out on a narrow scaffold in a high place, and replenishment work of tarpaulin rolls in such places is likely to drop disassembled parts and is troublesome. It uses the nerves.

  Moreover, although the Example shown by Unexamined-Japanese-Patent No. 2005-82260 is a structure where a core rod does not rotate, since many of waterproof sheet rolls do not have a core pipe and the shape of a core hole part is unstable, this When a waterproof sheet roll of this type is installed in this embodiment, the waterproof sheet near the core hole gets entangled with the core rod, resulting in excessive rotation resistance, and in some cases, the waterproof sheet cannot be pulled out during the work. There is a possibility of falling.

  Furthermore, in any of the examples, the deflection of the waterproof sheet roll tends to occur, and the work gradually becomes difficult as the construction proceeds. (The example of Unexamined-Japanese-Patent No. 2000-87558 generates a fixed resistance force at the time of pulling out a waterproof sheet, and does not prevent deflection.)

  On the other hand, in the embodiment shown in Japanese Patent Laid-Open No. 2000-314232, the shaft supporting the core hole of the waterproof sheet roll is only at one place below, and the unit is held by holding the top with a ring. Even if it is not disassembled, the waterproof sheet roll can be replenished.

  However, some of the waterproof sheet rolls have reverse winding directions. When such a waterproof sheet roll is used in this embodiment, the waterproof sheet roll needs to be mounted upside down. In most cases, the construction direction (back / up / down) is determined, so the above-mentioned method cannot be used in many cases.

  In this embodiment, the waterproof sheet roll gradually becomes thinner as the construction progresses, and the holding power of the ring is weakened. As a result, the structure of the waterproof sheet roll is inevitable as in the above-described embodiment.

  As described above, the construction of the waterproof sheet is difficult and inefficient, and imposes a great burden on the installer.

The above-mentioned portable holders of conventional tarpaulin rolls require disassembling part of the unit when the tarpaulin rolls are replenished. Then, there is a high possibility of dropping the disassembled parts, which is troublesome and nervous. Further, the tarpaulin roll is likely to bend, and the work gradually becomes difficult as the construction progresses.
An object of the present invention is to provide a portable holder for a waterproof sheet roll that overcomes the above-described problems and is easy to use.

  The above-mentioned problems include a support, a base fixed to both ends of the support, and a cantilever shaft on which the waterproof sheet roll can be supported between the bases, and at least one of the cantilever shafts is a waterproof sheet roll. A portable holder for a waterproof sheet roll having an elastic body that is movable in the axial direction and has a core bar that is pivotally supported by two cantilever shafts and that constantly presses the waterproof sheet roll from the side. It is solved by doing.

With the portable holder for tarpaulin rolls with the above structure, the tarpaulin rolls can be easily replenished in a short time without disassembling the unit even on a narrow scaffolding in high places, so that the construction is efficient and comfortable. Is possible.
Furthermore, since the elastic body that presses the waterproof sheet roll from the side always prevents the waterproof sheet roll from being bent, good workability can be maintained until the waterproof sheet roll is used up.

  The structure of the portable holder of the waterproof sheet roll according to the present invention (hereinafter referred to as a holder) will be described.

  In the holder according to the present invention, as shown in FIG. 1, the joint 2 is fixed to the upper end portion of the support column 1 with a set screw 3, and the base 4 is fixed to the upper surface portion of the joint 2 with screws 5.

  As shown in FIG. 2, a shaft hole 6 is provided on the base 4, and the shaft hole 6 has a cantilever shaft that penetrates the spring 7, the disk 8, and the washer 9 from the lower surface side of the base 4. 10 is inserted, and from the upper surface side of the base 4, a knob screw 12 is fastened to a female screw hole 13 of the cantilever shaft 10 through a seat washer 11. Since the step 14 is provided at the lower end of the cantilever shaft 10, the spring 7 does not fall out, and the washer 9 and the disk 8 are always in contact with the lower surface of the base 4 by the urging force of the spring 7. It is installed at.

  A leaf spring 15 is fixed to the side surface of the joint 2 with a screw 16. At this time, the longitudinal center line of the leaf spring 15, the axis of the waterproof sheet roll 17, and the axis of the column 1 are arranged so as to exist on the same plane. A hemispherical shape 18 is formed at the tip of the leaf spring 15 in a direction protruding to the waterproof sheet roll 17 side.

  Three hooks 19 are integrally formed on the base 4. At this time, the number and position of the hooks 19 may not be as illustrated.

  The above configuration is equally configured on the lower end surface side of the support column 1, and the cantilever shafts 10 arranged vertically support the both ends of the shaft tube 21 inserted through the core hole 20 of the waterproof sheet roll 17. ing.

  The overall height of the tarpaulin roll 17 is standardized and almost uniform. However, in the case of incorporating a tarpaulin roll having an exceptional special height, the setscrew 3 is loosened, the joint 2 is moved, The position may be finely adjusted.

  Next, the situation when the waterproof sheet is applied using the holder according to the present invention will be described.

  After forming the framework of the house, the installer hooks the hook 19 on the scaffold member 22 in the vicinity of the location where the waterproof sheet 23 starts to be applied, and hangs the waterproof sheet roll 17 together with the holder as shown in FIG. Stop. In the holder according to the present invention, since the hook 19 is provided in three directions, the hook that is most convenient to use may be used according to the posture and the position of the hooking position.

  After hooking the holder, the installer moves a certain distance along the wall while pulling the end of the waterproof sheet 23. At this time, the axial tube 21 inserted through the core hole 20 of the waterproof sheet roll 17, Since the disk 8 holding the upper and lower surfaces has a rotatable structure, the waterproof sheet roll 17 rotates smoothly on the holder, and the waterproof sheet 23 is pulled out as the installer moves.

  After pulling out the waterproof sheet 23 by a certain amount, the installer uses the needle punching machine 24 to stick the waterproof sheet 23 to the pillar 26 with the pins 25. When the pasting of the waterproof sheet 23 corresponding to the drawn-out is completed, the waterproof sheet 23 and the waterproof sheet roll 17 are separated therefrom and moved to another construction site.

  In the above description, the waterproof sheet 23 is pulled out and pasted after the holder is installed. However, after fixing the end face of the waterproof sheet 23 first, the holder 1 is used as a handle to hold the holder. There is also a method of moving along the wall surface in a state, hooking the holding member on the scaffold member 22 at an appropriate location, and then sticking the waterproof sheet 23 drawn out between them to the pillar 26.

  While continuing the construction, the waterproof sheet roll 17 becomes gradually thinner, but the leaf spring 15 installed in the joint 2 constantly presses the side surface of the waterproof sheet roll 17, so the waterproof sheet roll 17 is not easily bent and is good. Workability is sustainable.

  Further, since the hemispherical shape 18 is formed at the contact portion of the leaf spring 15 with the waterproof sheet roll 17, the waterproof sheet 23 can be smoothly pulled out without being caught by the edge portion of the leaf spring 15. Is possible.

  When the tarpaulin roll 17 is completely used and a new one is replenished, the upper knob screw 12 is pulled up to release the engagement relationship between the shaft tube 21 and the cantilever shaft 10 as shown in FIG. In this state, the shaft tube 21 is tilted to the opposite side of the support column 1, and after inserting a new waterproof sheet roll 17 through the shaft tube 21 from above, the shaft tube 21 is returned to the original position, and the knob screw 12 is released. The cantilever shaft 10 may be inserted again into the shaft tube 21 by the urging force of the spring 7.

  A fixed gap is secured between the cantilever shaft 10 and the shaft hole 6 and between the shaft tube 21 and the cantilever shaft 10 can swing within a fixed range. Therefore, the shaft tube 21 can be tilted to an angle sufficient to allow the waterproof sheet roll 17 to be inserted while being engaged with the cantilever shaft 10 on the lower side.

  In the above operation, since there are no parts to be removed from the unit and no special tool is used, the installer can easily refill the waterproof sheet roll 17 in a short time.

  By the way, there is a waterproof sheet roll in which a core tube 27 is separately incorporated in the core hole 20 part.

  When this type of waterproof sheet roll is used in the holder according to the present invention, the shaft tube 21 is not used, and the core tube 27 is directly supported by the upper and lower cantilever shafts 10 as shown in FIG. Also good.

  To replenish the waterproof sheet roll in this case, the upper knob screw 12 is pulled up, the old core tube 27 is removed, the lower end side of the core tube 27 of the new waterproof sheet roll is inserted into the lower cantilever shaft 10, and the waterproof sheet After the roll is set up vertically, the knob screw 12 on the upper side is released, and the cantilever shaft 10 may be inserted into the core tube 27 by the urging force of the spring 7. Compared with the method using the shaft tube 21 described above, Since the tarpaulin roll can be replenished with a smaller movement, it is particularly effective in a narrow and unstable place such as on a scaffold.

  Next, another example of use of the holder according to the present invention will be described.

  Since the holder according to the present invention has a plurality of hooks 19 symmetrically in the vertical direction, as shown in FIG. 6, it can be placed horizontally on the ground while the tarpaulin roll 17 is freely rotatable. . If the waterproof sheet 23 is pulled out in this state, the waterproof sheet can be attached in the vertical direction, which is an effective method particularly for high-rise buildings such as buildings.

  Further, until now, the installation of the holder according to the present invention has been described by the method of hooking the hook 19 to the scaffold member 22, but when there is no scaffold at the construction site and the holder cannot be installed by any means, it is shown in FIG. As described above, when the nail 28 is hit in advance on the pillar and the nail 28 is hooked on the key hole 29 formed on the hook 19, the holder can be hooked in the same manner as the hooking method on the scaffold member 22.
