Description

  The present invention relates to a curing instrument that has good operability and can be easily maintained.

  When renovating buildings, vinyl sheets (curing sheets) are installed at the relevant locations to prevent the formation of sections in the construction area and damage to walls. When such a curing sheet is attached to a ceiling surface or a wall surface, a curing device is used. FIG. 9 is an explanatory diagram showing an example of a curing instrument described in Patent Document 1. As shown in FIG.

  In the curing device shown in FIG. 9, the column 50 connects the upper beam member 54 and the lower beam member 55 and is fixed between the ceiling surface 59 and the floor surface 60. That is, the length of the column 50 is adjusted to the distance between the ceiling surface 59 and the floor surface 60 with the column 50 being compressed. As a result, both ends of the column 50 are pressed against the ceiling surface 59 or the floor surface 60 by the urging force of the elastic body in the rod 53. This curing device has a configuration of a telescopic pole in which the support column 50 extends and contracts.

  The support column 50 is provided with an inner cylinder 52 and an outer cylinder 51. The upper beam member 54 is provided with a close contact member 58. The upper beam member 54 is provided with a pressing spring 56, and the lower beam member 55 is provided with a pressing spring 57. When covering the curing sheet on the ceiling surface 59 or the wall surface, the curing sheet is placed on the contact member 58 and pressed against the ceiling surface 59. By supporting the curing sheet using a predetermined number of the support columns 50, the curing sheet is attached to a necessary portion such as a ceiling surface or a wall surface.

  FIG. 10 is an explanatory view showing an example according to another known curing device. This example is not described in the literature. In FIG. 10, the curing device 70 attaches a head plate 72 to a fixed base 71 connected to the telescopic pole via a support portion 76. A cover 73 is detachably fixed to the head plate 72. For this reason, the cover 73 can be removed from the head plate 72, the curing sheet 75 can be sandwiched between the two members, and the cover 73 can be fixed to the head plate 72.

  With the curing sheet 75 sandwiched, the expansion pole (not shown) is operated to press the upper surface of the cover 73 against the surface of the ceiling 74, and the lower part of the expansion / contraction pole is fixed to the floor surface. It becomes possible. Such an operation of the curing device can be handled by one worker, and there is an advantage that the curing sheet can be quickly installed.

JP 2000-120275 A

  Since the technique described in Patent Document 1 uses an expansion / contraction pole, operability is improved. However, this telescopic pole is not provided with a function of sandwiching the curing sheet. For this reason, it is necessary to hold the curing sheet on the ceiling surface or the like and then fix it with an extendable pole. In order for an operator to fix a curing sheet by a curing tool alone, it is necessary to fix the curing sheet to a ceiling surface or the like in advance with a tape or the like, and there is a problem that the work becomes complicated. Moreover, since the tape is stuck on the curing sheet, if the tape is peeled off after curing, the curing sheet is damaged, and cannot be reused and is treated as waste. For this reason, there is a problem that waste increases and a new curing sheet is required for each curing, which increases costs.

  Further, in the known technique shown in FIG. 10, since the curing sheet is sandwiched between the head plate and the cover, a gap is generated between the curing sheet and the mounting surface such as the ceiling surface, and dust generated in the construction from this clearance. Etc. leaked from the compartment to the outside. In addition, since the curing work is time-consuming, there is a problem that a worker of another occupation such as earthwork has to be put into the field when setting and removing the curing, and the work process is prolonged and the cost increases. .

  The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a curing device that is inexpensive, excellent in operability, and can be operated in a short time. .

  The curing device of the present invention that achieves the above object is a curing device provided with a head for fixing a curing sheet to an extendable pole, the head comprising a planar sheet holder for the curing sheet and a receiving member for the planar holder. And a groove is formed between the planar holder and the holder, a curing sheet is sandwiched between the planar holder and the holder and fixed in the groove, and the planar holder is cured. It abuts on the covering surface of the sheet.

  The present invention is characterized in that a spring is wound around the telescopic pole at a position close to the head, and a cover is attached to the outside of the spring.

  Further, the present invention is characterized in that a spherical recess is provided in the receiver, and a spherical member provided at the tip of the telescopic pole is fitted into the spherical recess so that the head can be tilted.

  Further, the present invention is characterized in that a plurality of ribs are provided radially at the lower part of the spherical member so as to have a truncated cone shape, and a space between the ribs is exposed to the outside.

  The curing device of the present invention has the following special effects. (1) A single worker can easily install and remove a curing sheet without the need for other auxiliary workers or other tools. For this reason, work man-hours can be reduced. (2) Curing work is easy and can be done by anyone in a short time, and no special skilled worker is required. (3) There is no gap between the ceiling sheet or the slab surface and other curing sheet mounting surfaces, dust does not flow in and out, and no post-processing such as weathering is required. (4) Curing can be performed simply by pulling the sandwiched curing sheet with an expansion / contraction pole. For this reason, it is not necessary to affix a tape on a curing sheet, and the complicated operation | work of affixing a tape becomes unnecessary and reuse of a curing sheet becomes easy. Moreover, since the curing sheet which has been used as waste after being used once can be used repeatedly, the amount of waste is reduced and the cost for curing can be reduced.

  The present invention will be described below with reference to the drawings. FIG. 1 is a partial perspective view of the curing device of the present invention as viewed from an obliquely upward direction, and FIG. 2 is a partial perspective view of the curing device of the present invention as viewed from an obliquely downward direction. 1 and 2, the curing device 1 has an upper spring receiver 2 and a lower spring receiver 3 attached to an extendable pole 5. A spring cover 7 will be described in detail later.

  A top 11 serving as a spherical fulcrum is disposed on the upper side of the upper spring receiver 2, and a curing plate holding plate 8 and a holder 9 for the holding plate 8 are placed on the top 11. The holding plate 8 functions as a planar holder. Reference numeral 10 denotes a narrow groove which is provided between the holding plate 8 and the support 9 and has a substantially U shape in cross section. A curing sheet is sandwiched between the holding plate 8 and the holder 9 and fixed in the narrow groove 10. Reference numeral 13 denotes a pin stopper that can fix the holding plate 8 to the support 9 by a one-touch operation. The holding plate 8 and the receiver 9 constitute a head portion of the curing device. This head portion uses ABS resin (acrylonitrile-butadiene-styrene terpolymer resin) to reduce the weight. In addition, the telescopic pole 5 is made of aluminum, so that the weight can be reduced.

  FIG. 3 is a diagram for explaining the details of the curing device of the present invention, FIG. 3 (b) is a plan view, and FIG. 3 (a) is a cross-sectional view showing the AA cross section of FIG. 3 (b). A mandrel 4 is provided on the upper side of the telescopic pole, that is, at the center near the head, and is fixed to the mandrel fixing part 20 with a screw 26. Reference numeral 17 denotes an inner cylinder. A spring 6 is wound around the mandrel 4, and the spring 6 is covered with a spring cover 7. Since the spring cover 7 is provided in this manner, the spring 6 can be prevented from being damaged by contact with other members from the outside, and the safety is improved.

  A spring fixing portion 24 a is provided on the outer peripheral portion 24 of the lower spring receiver 3, and the tip 6 a of the spring 6 is engaged with the spring fixing portion 24 a. Reference numeral 25 denotes a spring winding portion. The telescopic pole is extended from the lower spring receiver 3 by a predetermined length downward in the figure, and is supported on the floor surface. Such a telescopic pole mechanism is the same as that of the conventional example in FIG.

  The upper spring receiver 2 is provided with a rib 15 and a cylindrical portion 16. The top 11 provided on the upper portion of the mandrel 4 is fitted into a fitting portion 14 formed on the support 9 of the holding plate 8. The fitting part 14 has a spherical recessed part. The top 11 is joined to a mounting pin 23, and the mounting pin 23 is inserted and fixed in a cylindrical slot 4 a formed at the upper end of the mandrel 4. The mounting pin 23 and the top 11 are made of steel to increase the strength. Therefore, even when the reaction force from the ceiling surface and the pressing force from the telescopic pole are applied to the mounting pin 23 and the top 11 when attaching the curing sheet with the head abutting on the ceiling surface, etc. Damage to the member can be prevented.

  Since the top 11 has a spherical shape, it slides in the spherical recess of the fitting portion 14. For this reason, when the operator operates the curing tool, the holder 9 of the holding plate 8 can be tilted in each direction. Therefore, since the head can be freely moved according to the situation such as the position and shape of the portion to which the curing sheet is attached, the workability when attaching the curing sheet is improved.

  The curing sheet 20 is fixed in the narrow groove 10 formed between the holding plate 8 and the holder 9 as described above. The narrow groove 10 has a curved portion 10a on one side surface. Also, a curved portion 10b is formed on the other side surface. For this reason, the curing sheet is drawn into the curved portions 10a and 10b on both sides of the narrow groove 10 and is given tension. Therefore, the curing sheet can be attached to the head without sagging. When attaching the curing sheet 20 to the curing instrument 1, the pin stopper 13 is rotated and loosened, the holding plate 8 is slid and pulled out from the holder 9. A curing sheet is placed on the receiver 9, the holding plate 8 is slid along the narrow groove 10, fitted into the receiver 9, and fixed with a pin stopper 13.

  Thus, since the curing sheet 20 is fixed in the narrow groove 10 formed between the holding plate 8 and the holder 9, there is no gap between the holding plate 8 and the holder 9. For this reason, the dust generated by the construction does not leak from the curing sheet 20. In addition, there is no need for post-processes such as weathering. In addition, the narrow groove 10 formed between the holding plate 8 and the holder 9 does not need to be horizontal as shown in FIG. 3, and a tapered surface may be formed.

  In the embodiment of the present invention, a gapless plate can be realized. That is, a narrow groove is provided in the plate receiving portion that sandwiches the curing sheet, and the curing sheet is in direct contact with the ceiling surface or the building slab. By setting it as such a structure, the clearance gap between a ceiling surface or a slab bottom and a curing sheet is lose | eliminated, and inflow / outflow of dust etc. is lose | eliminated.

  Moreover, in embodiment of this invention, a curing instrument is comprised with the spring head which used the spring. That is, when the telescopic pole is pressed against the ceiling surface or the like, a spring is attached at a position close to the head of the telescopic pole in order to prevent damage to the ceiling material or the like. Furthermore, when supporting a ceiling surface etc. with a curing tool, it is set as the pin structure in which the angle of a head part is variable so that an expansion-contraction pole part can be extended easily.

  4A and 4B are diagrams for explaining the pin stopper 13, FIG. 4A is a plan view, and FIG. 4B is a partial cross-sectional view. The pin stopper 13 includes a push button portion 13a, a spring portion 13b, and a base portion 13c and is installed in a space provided in the holding plate 8. 4A, the pin stopper 13 is open, and the narrow groove 10 between the holding plate 8 and the receiving tool 9 is opened so that the curing sheet can be inserted.

  The push button portion 13a is locked by pressing the push button portion 13a from the state of FIG. 4A and rotating it in the R direction to move it to the OFF position. At this time, the holding plate 8 is in close contact with the support 9 and the narrow groove 10 is closed. Thus, since the open position and the lock position of the push button part 13a can be selected with one touch, the operability is improved. As shown in FIG. 4A, the push button portion 13a has open positions at both ends in the illustrated horizontal direction and off positions at both ends in the vertical direction. For this reason, the push button portion 13a can be rotated 360 degrees, and can be selected between open and off at an arbitrary 90-degree position.

  5A and 5B are views showing the spring cover 7, in which FIG. 5A is a perspective view and FIG. 5B is a plan view. As shown in FIG. 5, the spring cover 7 is provided with a space 7 a into which the mandrel 4 of the telescopic pole 5 is inserted at the center. For this reason, the overall shape is a hollow cylindrical shape. The spring cover 7 uses an appropriate member such as a synthetic resin.

  FIG. 6 is a view showing the upper spring receiver 2. FIG. 6A is a perspective view seen from an obliquely upward direction, and FIG. 6B is a perspective view seen from an obliquely downward direction. A plurality of triangular ribs 15 are attached to the fixed surface 2 a of the upper spring receiver 2 and the inner cylinder 18. Reference numeral 18 a denotes a hole for inserting the mounting pin 23 of the top 11, and 21 denotes a support for connecting the inner cylinder 18 and the cylindrical portion 6. In the example of FIG. 5, a plurality of ribs 15 are provided radially on the upper spring receiver 2 so as to have a truncated cone shape.

  Thus, the triangular spring 15 is radially attached to the upper spring receiver 2 between the inner cylinder 18 and the fixed surface 2a in the shape of a truncated cone, so that the strength of the upper spring receiver 2 is improved. A space 15a is formed between adjacent ribs and exposed to the outside. For this reason, it is a structure in which dust etc. do not stay easily, and even when dust adheres, it can be easily removed and maintenance is simplified.

  In the example of FIG. 3, the rib 15 has a triangular cross-sectional view with the tip narrowing toward the head. For this reason, there is an advantage that the head swing range can be increased without obstructing the movement when the head is tilted, as compared with the case where the rib is rectangular in sectional view. Furthermore, since the inner cylinder 18 and the cylindrical part 6 are connected by the support 21, the material cost can be reduced as compared with the case where the cylindrical part 6 is entirely formed of a cylindrical body up to the insertion hole 18a. Since the support rods 21 are arranged radially between the inner cylinder 18 and the cylindrical portion 6, sufficient strength can be obtained.

  8A and 8B are views showing the lower spring receiver 3. FIG. 8B is a plan view, and FIG. 8A is a cross-sectional view taken along the line BB in FIG. 8A and 8B, the mandrel fixing portion 20 is formed with a receiving seat 20a for a screw 26. Further, an inner peripheral portion 20 b of the mandrel fixing portion 20 is formed inside the inner cylinder 17. The support rods 22 are radially attached between the outer peripheral portion 24 and the inner peripheral portion 20b.

  The length X from the bottom surface of the spring fixing portion 24a formed on the outer peripheral portion 24 to the tip of the spring winding portion 25 supports the spring 6 shown in FIG. 3A, and the spring 6 is not curved. The shortest length is selected. That is, if the length of X is short, the spring 6 is bent when the spring 6 is shortened by the operation of the pole. If the length of X is unnecessarily long, the material is wasted.

  Therefore, the length of X is selected to be an optimum length that is sufficient to support the spring 6 and can prevent the spring 6 from being bent as long as the material is not wasted. As shown in FIG. 8A, a cavity is formed between the inside of the outer peripheral portion 24 and between the spring winding portion 25 and the inner cylinder 17 to reduce the weight.

  The telescopic pole according to the embodiment of the present invention has a shape that expands and contracts in a sliding manner without using a tool, and is fixed by twisting. In addition, when the curing sheet is sandwiched between the heads, it can be fixed by a one-touch operation without using a tool. Further, the head portion uses ABS resin (acrylonitrile-butadiene-styrene terpolymer resin), and the pole portion is made of aluminum. For this reason, the curing device is lightweight, has good workability, and is easy to move. The head mounting pins that require the most strength are made of steel to increase the strength.

  In such a curing device, a curing sheet is sandwiched between heads and placed on a ceiling or the like, and the length of the telescopic pole is adjusted to fix the lower fixing portion to the floor surface. Similarly, other curing equipment is installed at the necessary places to perform curing. At this time, the curing sheet can be applied to the ceiling / floor surface without any gaps by installing it while pulling the telescopic pole in the lateral direction.

  The embodiment of the present invention has been described above. The present invention is not limited to these examples, and various modifications are possible.

  As described above, according to the present invention, it is possible to provide a curing instrument that has good operability and can be easily maintained.
