DETAILED DESCRIPTION OF THE INVENTION

[0013] The following describes in detail an embodiment of an auxiliary set according to the present invention with reference to the accompanying drawings. First, [I] the basic concept of the embodiment will be explained, then [II] specific details of the embodiment will be explained, and finally, [III] modifications to the embodiment will be explained. However, the present invention is not limited to the embodiment.

[0014] [I] Basic Concept of the Embodiment First, the basic concept of the embodiment will be described. The embodiment generally relates to an auxiliary set (auxiliary tool) for assisting in driving a pin member into a wooden laminated timber using a driving tool.

[0015] Here, the term "driving tool" refers to a tool for driving pin members into wooden laminated lumber. This driving tool is a concept that includes, for example, a driving machine for drift pins (for example, a driving gun for drift pins) and / or a driving machine for pins other than drift pins (for example, a straight pin), but in the embodiment, it will be described as a driving gun for drift pins.

[0016] Furthermore, "wooden laminated lumber" refers to a construction member formed by combining multiple pieces of wood. This wooden laminated lumber is a concept that includes, for example, fire-resistant wooden laminated lumber (so-called fire-resistant wooden laminated lumber) and non-fire-resistant wooden laminated lumber, but in the embodiment, it will be described as a roughly board-shaped laminated lumber that has fire resistance.

[0017] Furthermore, fire-resistant wooden laminated lumber is a concept that includes, for example, a combination of multiple wooden fire suppression members, wooden fire-stopping members, and / or wooden load-indicating members, but in the embodiment, it will be described as comprising wooden load-indicating members, wooden fire-stopping members positioned outside the wooden load-indicating members, and wooden fire suppression members positioned outside the wooden fire-stopping members.

[0018] Furthermore, the specific type of "pin member" is arbitrary, and the concept includes, for example, drift pins and pins other than drift pins (for example, straight pins), but in the embodiment, it will be described as a drift pin.

[0019] [II] Specific details of the embodiment Next, specific details of the embodiment will be described.

[0020] (composition) First, the configuration of the auxiliary set 1 according to the embodiment will be described.

[0021] In the following description, the X direction in FIG. 1 is referred to as the left-right direction of the auxiliary set 1 (the -X direction is the left direction of the auxiliary set 1, and the +X direction is the right direction of the auxiliary set 1), the Y direction in FIG. 1 is referred to as the front-to-back direction of the auxiliary set 1 (the +Y direction is the front direction of the auxiliary set 1, and the -Y direction is the rear direction of the auxiliary set 1), and the Z direction in FIG. 1 is referred to as the up-down direction of the auxiliary set 1 (the +Z direction is the upward direction of the auxiliary set 1, and the -Z direction is the downward direction of the auxiliary set 1).

[0022] The auxiliary set 1 is intended to assist in driving a pin member 4 into a wooden laminated lumber 3 (hereinafter referred to as "wooden laminated lumber 3") using a driving tool 2, and as shown in Figure 1, it is provided with a guide portion 10.

[0023] In the embodiment, the pin member 4 is described as being driven into the wooden laminated timber 3 using an auxiliary set 1 and a driving tool 2 in order to join the wooden laminated timber 3 to another adjacent member 5 (for example, another wooden laminated timber or a steel member).

[0024] (Configuration - Guide section) The guide portion 10 is a guide means for guiding the driving portion 2a of the driving tool 2 (specifically, the approximately rod-shaped driving portion 2a having approximately the same outer diameter as the outer diameter of the pin member 4) so ​​that the pin member 4 is driven to the driving completion position, and as shown in Figure 1, it is provided with a first guide portion 20 and a second guide portion 30.

[0025] Here, the "driving completion position" means the position where the driving of the pin member 4 is completed, and in the embodiment, it is described as the position where the wooden laminated timber 3 can be joined to another adjacent member 5 via the pin member 4, as shown in Figure 4(c).

[0026] (Configuration - Guide section - First guide section) Returning to Figure 1, the first guide part 20 is part of the basic structure of the guide part 10 and can be attached to the driving tool 2, and as shown in Figures 1 and 2, it has a fitting part 21, a first guide main body part 22, and a restoring part 23.

[0027] (Configuration - guide part - first guide part - mating part) The fitted portion 21 is part of the basic structure of the first guide portion 20, and is fitted into the second guide portion 30 (specifically, a fitting hole 31a described below). The fitted portion 21 is formed of, for example, a substantially cylindrical body made of steel, and more specifically, is formed of a substantially cylindrical body having an inner diameter that allows the pin member 4 and the driving portion 2a of the driving tool 2 to be inserted therethrough.

[0028] Also, as shown in Figure 2, the mating portion 21 is located at the tip side of the first guide portion 20 (on the left side in Figure 2), and is provided at a position where the driving portion 2a of the driving tool 2 can be inserted into the mating portion 21.

[0029] As shown in FIG. 2, the fitted portion 21 is provided with a fitting prevention portion 24.

[0030] The fitting prevention portion 24 is intended to prevent the first guide main body portion 22 from being fitted with the second guide portion 30. The fitting prevention portion 24 is formed of, for example, a substantially annular body (specifically, a substantially circular annular body) made of steel, and specifically, is formed of a substantially circular annular body having an inner diameter larger than the outer diameter of the fitted portion 21 and an outer diameter larger than the outer diameter of the first guide main body portion 22.

[0031] As shown in FIG. 2, the fitting prevention portion 24 is provided at the end opposite to the tip side of the fitted portion 21 (the right end in FIG. 2), and is connected by welding or the like.

[0032] (Configuration - Guide section - First guide section - First guide main body section) The first guide body 22 is another part of the basic structure of the first guide part 20, and is capable of guiding the tip of the driving part 2a of the driving tool 2 up to approximately the tip of the fitted part 21. The first guide body 22 is formed of, for example, a substantially cylindrical body made of steel.

[0033] Specifically, the first guide main body portion 22 is formed as an approximately cylindrical body having a longitudinal length that is slightly shorter than the longitudinal length of the driving portion 2a of the driving tool 2, an inner diameter that allows the driving portion 2a of the driving tool 2 to be inserted therethrough, and an outer diameter that is approximately the same as the outer diameter of the mating portion 21.

[0034] As shown in FIG. 2, the first guide main body portion 22 is arranged to extend from the fitted portion 21 toward the side opposite to the tip side of the first guide portion 20 (to the right in FIG. 2), and is arranged in a position that allows the driving portion 2a of the driving tool 2 to be inserted into the first guide main body portion 22, and is connected to the fitted portion 21 and / or the fitting prevention portion 24 by welding or the like.

[0035] (Configuration - Guide section - First guide section - Restoration section) The restoring portion 23 is for returning the driving portion 2a to the state before being driven in after the driving portion 2a of the driving tool 2 has been driven in so that the tip of the driving portion 2a is guided by the first guide portion 20 up to approximately the tip of the fitted portion 21. The restoring portion 23 is made of, for example, a known spring material, and is attached so as to surround the first guide main body portion 22 and / or the driving portion 2a of the driving tool 2 between the fitting prevention portion 24 and the base end of the driving portion 2a of the driving tool 2, as shown in FIG.

[0036] Further, the method for attaching the restoring portion 23 is arbitrary, but in this embodiment, the restoring portion 23 is attached so that the first guide portion 20 is detachable from the driving tool 2.

[0037] Specifically, the tip end of the first guide portion 20 in the restoring portion 23 (the left end in FIG. 2) is connected to the tip end of the first guide portion 20 in the first guide main body portion 22 and / or to the mating prevention portion 24 by welding or the like, and the end opposite the tip side of the first guide portion 20 in the restoring portion 23 (the right end in FIG. 2) is attached by being detachably engaged with an engaging portion (not shown) at the base end of the driving portion 2a of the driving tool 2 or a portion nearby.

[0038] Such a first guide portion 20 allows the first guide portion 20 to be configured simply, and the manufacturability of the first guide portion 20 can be improved.

[0039] (Configuration - Guide section - Second guide section) Returning to Figure 1, the second guide section 30 is another part of the basic structure of the guide section 10, and is attachable to the wooden laminated timber 3 and can fit the first guide section 20. As shown in Figures 1 and 3, the second guide section 30 comprises a second guide main body section 31 and a protective section 32.

[0040] (Configuration - Guide section - Second guide section - Second guide main body section) The second guide main body 31 is part of the basic structure of the second guide part 30, and is for fitting the fitted part 21. The second guide main body 31 is formed of a generally plate-like wooden body having a fitting hole 31a (specifically, a generally circular through-hole) into which the first guide part 20 (specifically, the fitted part 21) can be fitted.

[0041] Specifically, the second guide main body 31 is formed of a generally plate-like body having a fitting hole 31 a with a diameter that is generally the same as the outer diameter of the fitted portion 21 .

[0042] As shown in FIG. 1, the second guide main body portion 31 is provided in multiple locations on the wooden laminated timber 3 via the protective portion 32 (four are provided in FIGS. 1 and 3), and is fixed to the protective portion 32 by a fastener or the like (or may be fixed to the protective portion 32 by a fastener or the like so as to be detachable).

[0043] (Configuration - Guide section - Second guide section - Curing section) The protective section 32 is another part of the basic structure of the second guide section 30, and is intended to prevent damage to the wooden laminated lumber 3 when the pin member 4 is driven into the wooden laminated lumber 3. The protective section 32 is formed of a generally plate-like wooden body having a guide insertion hole 32a (specifically, a circular through hole) through which the pin member 4 can be inserted but through which the fitted section 21 cannot be inserted.

[0044] Specifically, as shown in Figure 3, the protective section 32 is a substantially rectangular, plate-like body having a plurality of guide insertion holes 32a (six guide insertion holes 32a in Figure 3) with a diameter substantially the same as the outer diameter of the pin member 4, and is formed as a substantially plate-like body such that the width of the protective section 32 (length in the front-to-back direction in Figure 3) is longer than the width of the second guide main body section 31, and the height of the protective section 32 (length in the up-to-down direction in Figure 3) is longer than the height of the second guide main body section 31.

[0045] As shown in FIG. 1, the protective section 32 is provided between the second guide main body section 31 and the wooden laminated lumber 3, and is removably fixed to the wooden laminated lumber 3 by inserting a retaining member 33 (for example, a known retaining member such as a headed pin) into either the guide insertion hole 32a or one of a plurality of insertion holes 3a (specifically, insertion holes 3a having approximately the same diameter as the outer diameter of the pin member 4) provided in the wooden laminated lumber 3.

[0046] Furthermore, the arrangement of the guide insertion holes 32a is arbitrary, but in the embodiment, as shown in Figure 1, by inserting a retaining member 33 into at least one of the multiple guide insertion holes 32a, the guide insertion holes 32a are arranged so that when the protective section 32 is fixed to the wooden laminated timber 3, at least one of the guide insertion holes 32a into which the retaining member 33 is not inserted corresponds to one of the insertion holes 3a of the wooden laminated timber 3.

[0047] Specifically, when a plurality of insertion holes 3a are arranged in multiple rows at predetermined intervals along the width direction (front-to-back direction in Figure 1) and the vertical direction, a plurality of guide insertion holes 32a are similarly arranged in multiple rows at the above-mentioned predetermined intervals along the width direction and the vertical direction.

[0048] With this arrangement, the second guide portion 30 can be easily positioned according to the position where the pin member 4 is driven, and the ease of installation of the second guide portion 30 can be improved.

[0049] Such a second guide portion 30 can prevent damage to the wooden laminated lumber 3 compared to when the protective portion 32 is not provided (specifically, as shown in Figures 4(b) and 4(c), when the mating portion 21 is fitted into the fitting hole 31a, the protective portion 32 can prevent the mating portion 21 and the wooden laminated lumber 3 from coming into contact with each other, thereby preventing damage to the wooden laminated lumber 3 by the mating portion 21), thereby improving the usability of the second guide portion 30.

[0050] Furthermore, with the above-described auxiliary set 1, the work of driving the pin members 4 into the laminated wooden lumber 3 can be accurately performed by one worker M, and the workability of the work can be improved.

[0051] (Driving method) Next, a driving method using the auxiliary set 1 and the driving tool 2 will be described.

[0052] This driving method is a method of driving a pin member 4 into a wooden laminated lumber 3 using an auxiliary set 1 and a driving tool 2, and includes an attachment step, an installation step, a driving step, and a removal step.

[0053] The driving method will be described in the following embodiments on the assumption that it is performed as follows.

[0054] That is, the first guide part 20 is not attached to the driving tool 2. The second guide part 30 is not attached to the laminated wood lumber 3. The second guide main body part 31 is fixed to the curing part 32.

[0055] (Drive-in method - installation process) First, the mounting process will be described.

[0056] The attachment step is a step of attaching the first guide part 20 to the driving tool 2.

[0057] Specifically, the worker M inserts the driving portion 2a of the driving tool 2 into at least the first guide main body portion 22 of the first guide portion 20, and then attaches the driving tool 2 by engaging the end portion of the restoration portion 23 opposite the tip side of the first guide portion 20 with an engaging portion (not shown) that is connected to the base end portion of the driving portion 2a of the driving tool 2 or its nearby portion.

[0058] (Drive method - installation process) Next, the installation process will be described.

[0059] The installation step is a step of attaching the second guide portion 30 to the laminated wooden material 3 after the attachment step (or before or simultaneously with the attachment step).

[0060] Specifically, as shown in FIG. 1, worker M installs the protective section 32 by inserting the retaining members 33 into the multiple guide insertion holes 32a of the protective section 32 and the multiple insertion holes 3a of the wooden laminated timber 3, thereby fixing the protective section 32 to the wooden laminated timber 3.

[0061] In this case, the protective section 32 is positioned so that the guide insertion hole 32b through which the pin member 4 is inserted (hereinafter referred to as the "target guide insertion hole 32b"), which has not had the retaining member 33 inserted therethrough, corresponds to the insertion hole 3a of the wooden laminated timber 3.

[0062] (Drive method - Drive process) Next, the driving step will be described.

[0063] The driving step is a step of driving the pin members 4 into the laminated wooden lumber 3 after the attaching step and the installing step.

[0064] Specifically, first, as shown in Figure 4(a), worker M inserts pin member 4 into first guide portion 20, and then inserts pin member 4 into insertion hole 3a of wooden laminated lumber 3 via engagement hole 31a of second guide portion 30 and target guide insertion hole 32b.

[0065] Next, as shown in Figure 4(b), the worker M inserts the pin member 4 further deeper into the insertion hole 3a of the wooden laminated material 3 so that the mating portion 21 of the first guide portion 20 is mated with the mating hole 31a of the second guide portion 30.

[0066] 4(c), the worker M pushes the driving portion 2a of the driving tool 2 so that the tip of the driving portion 2a of the driving tool 2 is positioned almost up to the tip of the fitted portion 21. Then, the driving tool 2 drives the pin member 4 to the driving completion position, thereby joining the wooden laminated lumber 3 and the adjacent other member 5 via the pin member 4.

[0067] Here, when the pin members 4 are driven in by the driving tool 2, the pin members 4 can be guided by the guide section 10 (specifically, the first guide section 20 and the second guide section 30) (that is, the guide section 10 can prevent the pin members 4 from swinging back and forth and / or up and down), so even when the driving process is performed by a single worker M, it is possible to prevent the pin members 4, etc. from damaging the wooden laminated lumber 3 due to driving errors. Therefore, the driving process can be performed accurately by a single worker M, and the workability of the driving process can be improved.

[0068] Subsequently, as shown in FIG. 4(d), the worker M drives the pin member 4 to the driving completion position, and then removes the driving portion 2a of the driving tool 2 from the second guide portion 30.

[0069] For example, when driving the pin members 4 into a plurality of target guide insertion holes 32b, the above-described operations corresponding to FIGS. 4(a) to 4(d) may be repeated a plurality of times.

[0070] Furthermore, when driving pin members 4 into multiple target guide insertion holes 32b, if it is necessary to attach the second guide portion 30 to the wooden laminated material 3, the work corresponding to the installation process and the work corresponding to the above-mentioned Figures 4(a) to 4(d) may be repeated multiple times.

[0071] (Insertion method - removal process) Next, the removal process will be described.

[0072] The removing step is a step of removing the guide portion 10 (specifically, the first guide portion 20 and the second guide portion 30) after the driving step.

[0073] Specifically, the worker M removes the first guide part 20 by detaching the restoring part 23 from the base end of the driving part 2a of the driving tool 2 or a part nearby, and by removing the driving part 2a of the driving tool 2 from the first guide main body part 22, etc. In addition, the worker M removes the second guide part 30 from the wooden laminated lumber 3 by removing the holding member 33 from the wooden laminated lumber 3, thereby removing the second guide part 30.

[0074] By using such a driving method, one worker M can efficiently drive the pin members 4 into the laminated wooden lumber 3, thereby improving the workability of the work.

[0075] (Effects of the embodiment) Thus, according to the embodiment, a guide portion 10 is provided for guiding the driving portion 2a of the driving tool 2 so that the pin member 4 is driven to the driving completion position, and the guide portion 10 is provided with a first guide portion 20 that can be attached to the driving tool 2, and a second guide portion 30 that can be attached to the wooden laminated lumber 3 and into which the first guide portion 20 can be fitted.Therefore, the work of driving the pin member 4 into the wooden laminated lumber 3 can be accurately performed by a single worker M, and the workability of the work can be improved.

[0076] Furthermore, the first guide portion 20 comprises a fitted portion 21 that is fitted into the second guide portion 30, and a first guide main body portion 22 that can guide the tip portion of the driving portion 2a up to approximately the tip of the fitted portion 21, so that the first guide portion 20 can be easily constructed and the manufacturability of the first guide portion 20 can be improved.

[0077] In addition, the second guide portion 30 comprises a second guide main body portion 31 having an engagement hole 31a into which the first guide portion 20 can be fitted, and a protective portion 32 for preventing damage to the wooden laminated lumber 3 when the pin member 4 is driven into the wooden laminated lumber 3. Therefore, damage to the wooden laminated lumber 3 can be prevented more effectively than in the case where the protective portion 32 is not provided, and the usability of the second guide portion 30 can be improved.

[0078] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions set forth in the claims.

[0082] (Regarding the second guide section) In the above embodiment, the second guide section 30 is described as being provided with the protective section 32, but this is not limited to this. For example, if there is no risk of damage to the laminated wooden material 3 (or if such damage is acceptable), the protective section 32 may be omitted.

[0083] In this case, for example, the second guide body portion 31 may be detachably fixed to the wooden laminated material 3 by a fastener or the like.

[0084] Furthermore, in the above embodiment, it has been described that multiple second guide main body portions 31 are provided in the protective section 32, but this is not limited to this, and for example, only one second guide main body portion 31 may be provided in the protective section 32.

[0085] In the above embodiment, it has been described that a plurality of guide insertion holes 32a are provided in the curing section 32, but this is not limiting. For example, if the curing section 32 is detachably attached to the laminated wooden material 3 by other fixing means, only one guide insertion hole 32a may be provided in the curing section 32.

[0086] (Addendum) The auxiliary set of Appendix 1 is an auxiliary set for assisting in driving a pin member into a wooden laminated timber using a driving tool, and is provided with guide means for guiding the driving portion of the driving tool so that the pin member is driven to the driving completion position, and the guide means is provided with first guide means that can be attached to the driving tool, and second guide means that can be attached to the laminated timber and into which the first guide means can be fitted.

[0087] The auxiliary set of Appendix 2 is the auxiliary set described in Appendix 1, wherein the first guide means comprises a fitted portion that fits into the second guide means, and a first guide main body portion that can guide the tip of the driving portion to approximately the tip of the fitted portion.
