Description

  TECHNICAL FIELD The present invention relates to a heat-insulating-material fixing auxiliary tool, and more particularly, to a heat-insulating-material fixing auxiliary tool used when fixing a heat insulating material to a base material.

  2. Description of the Related Art Conventionally, there has been known a construction method in which a driven material is fixed to a casing by driving a screw into the casing (base material) via a heat insulating material fixture and the driven material using an electric screwdriver. When such an electric screwdriver is used, it is necessary to apply a screw to the tip of the electric screwdriver one by one, and there is a disadvantage that the construction speed is reduced.

  For this reason, in general, in order to improve the construction speed, from a nail or a high-pressure screwing machine that is injected from a high-pressure nailing machine using a high-pressure nailing machine or a high-pressure screwing machine that uses compressed air. A construction method is known in which a screw to be driven is fixed to a casing by driving an injected screw into the casing (underlying material) through a heat insulating material fixture and the target to be driven.

  As an example of the above-described driven material, when a highly flexible driven material such as a heat insulating material is fixed to the housing, the driven material is easily elastically deformed. It is necessary to press the screw driving machine against the material to be driven and hold it in a predetermined position, and to keep the injection direction of the nail or screw perpendicular to the surface to be driven of the material to be driven.

  Also, when using a high-pressure nailing machine or high-pressure screw driving machine, it is necessary to drive nails or screws while supporting the insulation fixing tool with your hands (fingertips), and there is a risk of hitting your hands (fingertips) by mistake. Therefore, various attachment aids that can hold the heat insulating material fixture safely and stably have been proposed.

  Three guide pins (attachment aids) are attached to the nail injection portion of the high-pressure nailing machine disclosed in Patent Document 1 along the nail injection direction. These guide pins are provided with a substantially disc-shaped flange (insulating material fixture). Three guide holes are formed in the peripheral edge of the flange, and each guide pin is inserted into each guide hole. One through hole is formed at the center of the flange.

  In addition, when attaching the material to be driven to the housing, each guide pin penetrates the material to be driven by pressing each guide pin of the high-pressure nailing machine against the material to be driven and the housing. The end of the guide pin comes into contact with the housing. Thereby, each guide pin is hold | maintained in a perpendicular | vertical state with respect to a housing.

  Then, with each guide pin held perpendicular to the housing, the nail is ejected from the nailing machine toward the driven material, so that the nail penetrates the driven material and enters the housing. . At this time, the guide hole of the flange attached to the guide pin is guided in the injection direction while being inserted through the guide pin, so that the workpiece is pressed (fixed) to the housing by the flange.

  Thereby, the nail is guided in the extending direction of the guide pin together with the flange, and is driven perpendicularly to the housing. In this way, since the nail is ejected with the three guide pins penetrating the workpiece, when nailing a highly flexible workpiece into the housing, the nail is driven perpendicular to the housing. It is possible.

JP 2005-59158 A

  However, in the prior art disclosed in Patent Document 1, when the material to be driven is fixed to the housing, three guide pins (attachment aids) are driven into the material to be driven. There is a problem of damaging (insulating material). In addition, when a material to be driven is fixed to the housing, there is a problem similar to the above even when a high-pressure screwdriver using compressed air is used.

  This invention is made | formed in view of the said subject, Comprising: It aims at providing the attachment auxiliary tool of the heat insulating material fixing tool which can improve a construction precision, without damaging a heat insulating material.

  As means for solving the above-mentioned problems, the heat-insulating-material fixing tool mounting aid according to the present invention is configured as follows.

  That is, the heat-insulating-material fixing auxiliary tool according to the present invention includes a screw injected from an injection port of a high-pressure screwdriver using compressed air and a shaft portion of the screw to insulate the tip of the screw. A configuration used when fixing the heat insulating material to the base material by a heat insulating material fixing tool having a flange on one end side of a sleeve in which a hollow portion that guides to a wooden or steel base material through the material is formed Is assumed.

  Further, the heat-insulating material fixing tool mounting aid according to the present invention includes a flat bottom surface, a pair of wall surfaces extending in a vertical direction from the bottom surface, and a front surface provided at one end of the bottom surface and the wall surface, The region surrounded by the bottom surface, the pair of wall surfaces, and the front surface is configured such that an injection port of the high-pressure screwdriver is applied, and a distal end portion of the sleeve of the heat insulating material fixing tool is the high-pressure screw. The flange of the heat insulating material fixture is placed on the front surface so that the shaft center of the sleeve of the heat insulating material fixing device and the shaft center of the injection port of the high pressure screw driving device are aligned with the injection direction of the hammer It is characterized in that a pocket for holding is formed.

  According to the mounting aid for the heat insulating material fixture having such a configuration, first, when fixing the heat insulating material to the base material, with the heat insulating material fixing device attached to the mounting auxiliary device, high-pressure screwing is applied to the mounting auxiliary device. Apply the machine's injection port. Next, after the injection port of the high-pressure screwing machine is pressed against the front surface of the mounting aid and the heat insulating material, the trigger of the high-pressure screwing machine is pulled, so that the screw is injected (dried). Thereafter, the mounting aid is removed from the heat insulating material fixture by sliding the mounting aid from the heat insulating material fixing device in a predetermined direction (for example, downward). Thereby, construction accuracy can be improved, without damaging a heat insulating material.

  Moreover, since a general high-pressure screwdriver is filled with screws in advance, the working speed can be increased as compared with an electric screwdriver. Therefore, by using a high-pressure screwdriver, the construction speed can be made faster than the conventional method using an electric screwdriver.

  In addition, by using the mounting aid, when the screw is injected from the high-pressure screwdriver, the screw and the heat insulating material fixture do not fall over the base material. It is possible to strike at a right angle with respect to the surface of the steel, and the construction accuracy can be improved.

  In addition, when the screw is injected toward the base material, the mounting aid functions to protect the hand (fingertip) holding the heat insulating material fixture from the injection port of the high-pressure screwdriver, thus ensuring safety. Can do.

  Conventionally, in the operation of supporting the screw with the left hand and rotating and tightening the screw with an electric screwdriver with the right hand, for example, when the screw is relatively short, it is difficult to support the screw with a finger, so the screw is likely to fall down. Become. On the other hand, in the present invention, the high-pressure screwdriver and the mounting aid can be used even in fixing a relatively short screw.

  As specific configurations of the present invention, the following plural ones are listed.

  In the mounting aid for a heat insulating material fixing tool according to the present invention, preferably, on the bottom surface, the height positions of the shaft center of the sleeve of the heat insulating material fixing tool and the shaft center of the injection port of the high pressure screwdriver are provided. An adjustment spacer for adjustment is provided. If comprised in this way, since the height of the axial center of the injection port of a high-pressure screwing machine can be matched with the axial center of the sleeve (flange) of a heat insulating material fixing tool, from the injection port of a high-pressure screwing machine The screw can be accurately injected into the shaft center of the sleeve of the heat insulating material fixture.

  Also, in the heat-insulating-material fixing tool mounting aid according to the present invention, the high-pressure screw driver releases the safety device by pressing the injection port a predetermined distance along the injection direction, and pulls the trigger to The safety device is provided so that the screw is injected from the injection port. Therefore, preferably, the length of the attachment auxiliary tool in the direction along the injection direction is set to a dimension that does not hinder the release of the safety device. With this configuration, when the injection port of the high-pressure screwdriver is pressed against the front surface of the mounting aid by a predetermined distance, the bottom surface or a pair of wall surfaces of the mounting aid and the side surface of the main body of the high-pressure screwdriver are injected. Since it can suppress contacting along a direction, a safety device can be canceled certainly. As a result, the screw can be smoothly injected from the high-pressure screwdriver to fix the heat insulating material to the base material.

  Moreover, in the heat-insulating-material fixing tool mounting aid according to the present invention, the front surface is constituted by a first front surface, a second front surface, and a third front surface that are sequentially arranged along the injection direction of the high-pressure screwdriver. A substantially U-shaped flange holding portion for holding the flange of the heat insulating material fixture is formed on the second front surface. Preferably, the pocket for holding the flange of the heat insulating material fixture is formed by sandwiching the second front surface having the substantially U-shaped flange holding portion between the first front surface and the third front surface. The first front surface, the second front surface, and the third front surface are fixed to a small edge at one end of the bottom surface and the wall surface. If comprised in this way, the pocket for hold | maintaining the flange of a heat insulating material fixing tool can be formed easily, and it can hold | maintain so that the flange of a heat insulating material fixing tool may not move by a pocket. As a result, the injection port of the high-pressure screwdriver and the axis of the sleeve of the heat insulating material fixture can be easily matched.

  In this case, it is preferable that a notch-shaped sleeve holding portion for holding a sleeve of the heat insulating material fixture is formed in the vicinity of the center portion of the third front surface. If comprised in this way, since the sleeve of a heat insulating material fixing tool becomes difficult to move with respect to an attachment auxiliary tool, when fixing a heat insulating material to a base material, the injection port of a high-pressure screwdriver and a heat insulating material fixing tool It is possible to easily match the axial center of the sleeve.

  In the configuration including the first front surface, the second front surface, and the third front surface, the second front surface is preferably disposed on the surface of the first front surface on the third front surface side or the surface of the third front surface on the first front surface side. A pressing member that presses the flange of the heat insulating material fixture held by the flange holding portion toward the third front surface side or the first front surface side is provided. If comprised in this way, between a 1st front surface and a 3rd front surface, since a heat insulating material fixture can be made hard to remove | deviate by pressing (temporary pressing), it can hold | maintain more stably.

  In this case, it is preferable that the pressing member includes two leaf springs extending along a direction perpendicular to the bottom surface with the center of the first front surface or the third front surface interposed therebetween. If comprised in this way, since two leaf | plate springs press (bias) two places of the flange of a heat insulating material fixture to the 3rd front surface side or the 1st front surface side, a heat insulating material fixture is hold | maintained stably. be able to.

  As described above, according to the mounting aid for a heat insulating material fixture according to the present invention, construction accuracy can be improved without damaging the heat insulating material.

Next, a construction method (procedure) for fixing the heat insulating material 4 to the base material 5 using the mounting aid 1 and the screw 21 will be described with reference to FIGS.

  As shown in FIG. 13, the heat insulating material fixture 3 is fitted into the mounting aid 1. Specifically, the heat insulating material is fixed to the pocket 130 (the portion surrounded by the flange holding portion 132a of the second front surface 132, the first front surface 131, and the third front surface 133) formed on the front surface 13 of the attachment assisting tool 1. The flange 31 of the tool 3 is fitted (attached). At this time, the flange 31 of the heat insulating material fixture 3 is fitted into the pocket 130 of the mounting aid 1 so as to resist the urging force of the two leaf springs 15 provided on the first front surface 131.

  Next, the high-pressure screwdriver 2 between the bottom surface 11, the pair of wall surfaces 12 and the front surface 13 (first front surface 131) of the mounting assisting tool 1 with the heat insulating material fixing tool 3 fitted in the mounting assisting tool 1. The injection port 29a is applied (mounted).

  The user supports the bottom surface 11 and the wall surface 12 of the mounting aid 1 from below with the left hand (right hand) and holds the high-pressure screwdriver 2 with the right hand (left hand) as shown in FIG. The injection port 29a of the high-pressure screwdriver 2 is pressed against the front surface 13 (first front surface 131). At this time, the safety device is released (removed) by sliding the high-pressure screwdriver 2 by the distance (L1-L2) along the contact arm 210 (see FIG. 2), and the trigger 28 is activated. . Thereafter, by pulling the trigger 28 (see FIG. 2), the screw 21 is injected (injected) into the base material 5 through the heat insulating material 4 from the injection port 29 a of the high-pressure screwdriver 2.

  Thereafter, the mounting aid 1 is removed from the heat insulating material fixture 3 and the screw 21 by sliding the mounting aid 1 downward. Thereby, as shown in FIG. 15, the construction which fixes the heat insulating material 4 to the base material 5 using the attachment auxiliary tool 1 is completed.

  As explained above, according to the mounting aid 1 of the heat insulating material fixture 3 according to the present embodiment, the effects listed below can be obtained.

  In the present embodiment, as described above, with the tip 32b of the sleeve 32 of the heat insulating material fixture 3 facing the injection direction of the high pressure screwing machine 2, the shaft center of the sleeve 32 of the heat insulating material fixing device 3 and the high pressure A pocket 130 for holding the flange 31 of the heat insulating material fixture 3 is formed on the front surface 13 so that the axis of the injection port 29a of the screwdriver 2 is aligned. Thereby, first, when the heat insulating material 4 is fixed to the base material 5, the injection port 29 a of the high-pressure screwdriver 2 is applied to the mounting aid 1 with the heat insulating material fixture 3 attached to the mounting aid 1. Go (put). Next, after the injection port 29a of the high-pressure screwing machine 2 is pressed against the front surface 13 and the heat insulating material 4 of the mounting aid 1, the screw 21 is injected (pulling) by pulling the trigger 28 of the high-pressure screwing machine 2. ) Thereafter, the attachment auxiliary tool 1 is detached from the heat insulating material fixing tool 3 by sliding the attachment auxiliary tool 1 from the heat insulating material fixing material 3 in a predetermined direction (for example, downward). Thereby, the construction accuracy can be improved by driving the heat insulating material fixture 3 and the screw 21 substantially perpendicularly to the base material 5 without damaging the heat insulating material 4.

  Moreover, since the general high-pressure screwdriver 2 is filled with the screw 21 in advance, the working speed can be increased as compared with the electric screwdriver. Therefore, by using the high-pressure screwdriver 2, the construction speed can be made faster than the conventional method using an electric screwdriver.

  Moreover, when the screw 21 is injected from the high-pressure screwdriver 2 by using the mounting aid 1, the screw 21 and the heat insulating material fixture 3 do not fall down with respect to the base material 5. The tool 3 and the screw 21 can be struck at right angles to the surface of the base material 5 and the construction accuracy can be improved.

  Further, when the screw 21 is injected toward the base material 5, the mounting aid 1 serves a function of protecting the hand (left hand or right hand) holding the heat insulating material fixing tool 3 from the injection port 29 a of the high-pressure screwdriver 2. Therefore, safety can be ensured.

  Conventionally, in the operation of supporting the screw with the left hand and rotating and tightening the screw with an electric screwdriver with the right hand, for example, when the screw is relatively short, it is difficult to support the screw with a finger, so the screw is likely to fall down. Become. On the other hand, in the present invention, the high-pressure screwdriver 2 and the mounting aid 1 can be used even in fixing a relatively short screw.

The adjusting spacer 14 is provided. Thereby, the height of the axial center of the injection port 29a of the high-pressure screwing machine 2 can be matched with the axial center of the sleeve 32 (flange 31) of the heat insulating material fixture 3, so The screw 21 can be accurately injected from the outlet 29a to the axis of the sleeve 32 of the heat insulating material fixture 3.

  Further, in the present embodiment, as described above, the length L3 in the direction along the injection direction of the bottom surface 11 of the attachment assisting tool 1 is set to a dimension that does not hinder the release of the safety device. Thus, when the injection port 29a of the high-pressure screwdriver 2 is pressed against the front surface 13 of the mounting aid 1 by a predetermined distance (L1-L2), the end portion 11b of the bottom surface 11 of the mounting aid 1 or the pair of wall surfaces 12 is used. Since it can suppress that the edge part of the high pressure screwing machine 2 side and the side surface 24a of the body 24 of the high pressure screwing machine 2 contact along the injection direction, the safety device can be reliably released. it can. As a result, the screw 21 can be smoothly injected from the high-pressure screwdriver 2 to fix the heat insulating material 4 to the base material 5.

  In the present embodiment, as described above, the second front surface 132 having the substantially U-shaped flange holding portion 132a is sandwiched between the first front surface 131 and the third front surface 133, so A pocket 130 for holding the flange 31 is formed, and the first front surface 131, the second front surface 132, and the third front surface 133 are fixed to the bottom surface 11 and a small edge (end portion) at one end of the pair of wall surfaces 12. Thereby, the pocket 130 for holding the flange 31 of the heat insulating material fixture 3 can be easily formed, and the flange 31 of the heat insulating material fixing device 3 can be held by the pocket 130 so as not to move. . As a result, the injection port 29a of the high-pressure screwdriver 2 and the axis of the sleeve 32 of the heat insulating material fixture 3 can be easily matched.

  In the present embodiment, as described above, the sleeve holding portion 133 b that holds the sleeve 32 of the heat insulating material fixture 3 is formed in the vicinity of the center portion of the third front surface 133. As a result, the sleeve 32 of the heat insulating material fixing tool 3 is less likely to move with respect to the mounting aid 1, so that when the heat insulating material 4 is fixed to the base material 5, the injection port 29 a of the high pressure screwdriver 2 and the heat insulating material are used. The axial center of the sleeve 32 of the fixture 3 can be easily matched.

  In the present embodiment, as described above, the flange 31 of the heat insulating material fixture 3 held by the flange holding portion 132a of the second front surface 132 is provided on the surface of the first front surface 131 on the third front surface 133 side. A leaf spring 15 is provided to press on the front surface 133 side. Thereby, between the 1st front surface 131 and the 3rd front surface 133, since it can make it difficult to remove | deviate the heat insulating material fixing tool 3 by a press (temporary pressing), it can hold | maintain more stably.

  In the present embodiment, as described above, the two leaf springs 15 extending along the vertical direction with respect to the bottom surface 11 are provided with the center of the first front surface 131 interposed therebetween. Thereby, since the two leaf | plate springs 15 press (bias) two places of the flange 31 of the heat insulating material fixing tool 3 to the 3rd front surface 133 side, the heat insulating material fixing device 3 can be hold | maintained stably.

  Moreover, in this embodiment, as mentioned above, the space | interval of a pair of wall surface 12 is set to the same dimension as the outer diameter of the injection port 29a of the high pressure screwdriver 2, or a slightly larger dimension than it. Thereby, since it can suppress that the injection port 29a of the high pressure screwdriver 2 moves between the wall surfaces 12, the axial center of the injection port 29a of the high pressure screwdriver 2 and the sleeve 32 of the heat insulating material fixture 3 is possible. Can be easily matched.

  Further, in the present embodiment, as described above, the width W3 of the flange holding portion 132a of the second front surface 132 is formed to have the same dimension as or slightly larger than the outer diameter of the flange 31 of the heat insulating material fixture 3. To do. Thereby, since the flange 31 of the heat insulating material fixture 3 becomes difficult to move with respect to the mounting aid 1, when fixing the heat insulating material 4 to the base material 5, the injection port 29 a of the high pressure screwdriver 2 and the heat insulating material are used. The axial center of the sleeve 32 of the fixture 3 can be easily matched.

  Further, in the present embodiment, as described above, the sleeve holding portion 133b formed in the vicinity of the center portion of the third front surface 133 is the same as or slightly smaller than the outer diameter of the sleeve 32 of the heat insulating material fixture 3.

As a result, the sleeve 32 of the heat insulating material fixture 3 is more difficult to move with respect to the mounting aid 1, and therefore, when fixing the heat insulating material 4 to the base material 5, the heat insulating material 4 is insulated from the injection port 29 a of the high pressure screwdriver 2. The axial center of the sleeve 32 of the material fixture 3 can be easily matched.

  Further, in the present embodiment, as described above, the sleeve holding portion 133b formed on the upper end portion 131d of the first front surface 131 and the upper end portion 133d of the third front surface 133 in the vicinity of the center portion of the third front surface 133, respectively. A notch 131a and a notch 133a having a width larger than the width are formed. Thereby, since the flange 31 of the heat insulating material fixture 3 can be grasped via the notches 131a and the notches 133a, the heat insulating material fixing device 3 is attached to the pocket 130 (flange holding portion 132a) of the mounting aid 1. Or removal can be performed easily.
