Description

  The present invention relates to a column clamp for attaching a column to various members installed at various construction sites.

  Typical examples of various members at various construction sites include “sheet piles”, “H steel”, and “casing” for excavating uprights. These various members are provided with “temporary materials” as described below.

  At various construction sites, in order to protect the construction site, to ensure the safety of workers, and to let passers-by know that it is a construction site, "fence", "ladder", "scaffold", " It is necessary to install various temporary materials such as “signboards” or “roofs”. Temporary materials such as these “fences”, “ladders”, “scaffolds”, “signboards”, or “roofs” are usually provided with “posts”. Temporary materials such as “fence”, “ladder”, “scaffolding”, “signboard”, or “roof” are fixed.

  Of course, these temporary materials such as "fence", "ladder", "scaffolding", "signboard", or "roof" can become dangerous goods unless the struts are firmly fixed to the various members. The column must be fixed firmly. Note that the “post” is usually set up in the “vertical direction” with respect to the member. For example, in the case of a “signboard” or a “flag” indicating the construction company or the construction status, May be fixed in the “lateral direction”.

  As a conventional technique for fixing the support column as described above, for example, there is a technique proposed in Patent Document 1.

JP2011-241558, abstract, FIG.

  The “handrail mounting bracket” proposed in Patent Document 1 provides a “handrail mounting bracket that enables easy installation work and disassembly work of a fall-preventing handrail installed at the upper end of a sheet pile. As shown in FIG. 11, “a pair of rectangular pieces, a connecting piece for connecting the rectangular pieces on one long side so as to maintain a predetermined gap, and a rectangular shape” An arm member that is slidably disposed in a gap between the pieces, a grip portion that is disposed at a predetermined interval from the other long side that faces one long side of the rectangular piece, and is fixed to the grip portion. The arm member is formed in an arc shape that is convexly curved toward the other long side, and the upper end of the sheet pile is spaced between the other long side and the gripping part. And slide the arm member downward in the gap between the rectangular pieces to make it convex By projecting the song with edges in the gap, a handrail mounting bracket "that is configured to secure by sandwiching the sheet pile between the gripper edge which is convexly curved.

  In the “handrail mounting bracket” of Patent Document 1, “the arm member is slid downward in the gap between the rectangular pieces, and the edge curved in a convex shape is projected into the gap. Since the sheet pile is sandwiched and fixed between the curved edge portion and the grip portion, the arm member must be moved upward in order to release this fixation.

  In order to move the arm member upward in the “handrail mounting bracket” of Patent Document 1, as described in Paragraph 0019 of the Patent Document 1, “When trying to remove the handrail” In other words, it is necessary to remove the strut (single tube) from the single tube storage portion 24 and then hit the lower end 16e of the arm member 16 several times with a hammer. However, in the operation of “striking the lower end 16e of the arm member 16 several times with a hammer”, there is sufficient space for the hammer to swing under the lower end 16e of the arm member 16, or the lower end 16e of the arm member 16 is close to the chest of the operator. If it does not exist, it cannot be performed reliably. The operation of swinging a heavy tool such as a horn or a hammer upward from the bottom is usually a difficult task.

  Therefore, the present inventors have made it possible to fix this kind of support clamp to the support member and to release it only by swinging down the hammer, that is, by operating from only one of the hammers. As a result of various studies on what should be done, the present invention has been completed.

  That is, the object of the present invention is to provide a column clamp that can be fixed and fixed to the member by only one of the tools and can be used easily. There is to do.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the embodiments described later.
“A column clamp 10 for attaching the column 20 to a member 30 installed at a construction site,
A column support 11 disposed on one side of the member 30 to which the column 20 is attached;
A base 12 that is integrated with the column receiving part 11 and the assembly part 12a extends to the other side of the member 30;
A wedge 13 having a striking portion 13a, which is movably assembled to the assembly portion 12a of the base portion 12 and presses one side of the member 30 toward the abutting portion 12b provided on the base portion 12,
The wedge 13 and is assembling unit et assembled to 12a so as to relatively moving the opening member 14 having a striking portion 14a which is beaten from the same side as the striking portion 13a of the wedge 13,
Mounted on pivot 15a on the attaching portions 12a which is located between the opening member 14 and the wedge 13, abuts or is connected to the wedge 13 at one end 15b, abut against or connected to the other end 15c to opening member 14 a seesaw 15 that it was,
A temporary support pole clamp 10 characterized by comprising:
It is.

  The column clamp 10 configured as described above is used to make “sheet pile”, “H steel”, “casing”, etc. installed at various construction sites as shown in FIGS. 9 and 10. A column 20 constituting various temporary members such as a “fence”, “ladder”, “scaffold”, “signboard”, or “roof” is fixed to various members 30. If fixing of 20 becomes unnecessary, the operation described below is performed to remove the support column 20 from the member 30. FIG. 9 shows an example in which a plurality of support columns 20 are erected at the upper end of the “sheet pile” that is the member 30 and a temporary material called “fence” is configured using these support columns 20. .

In the examples shown in FIG. 9 and FIG. 10, each support column 20 is directed in the vertical direction. However, as described above, the support column 20 is set to the “lateral direction” in order to attach the “flag” or the “signboard”. Even when used, the column clamp 10 according to the present invention can be used. However, in the following description of the operation of the column clamp 10, the description will focus on the case where the column 20 is erected on the member 30. Needless to say, the vertical direction is as shown in FIG. This is because the hitting portion 14a of the opening member 14 is hit from the same side as the hitting portion 13a of the wedge 13, so that when the hitting portion 13a of the wedge 13 is hit from the lateral direction, the same lateral direction This is because the hitting portion 14a is also hit.

  First, as shown in FIG. 1 and FIGS. 4 to 8, a member insertion portion 12 c is formed on the base 12 constituting the column clamp 10, and in this case, the member insertion portion 12 c is Since the lower part is opening, the upper end of the member 30 will be inserted in this member insertion part 12c. In the case of the embodiment described later, the base 12 is composed of two pieces so as to sandwich the wedge 13, the opening member 14, and the seesaw 15, but the wedge 13, the opening member 14, and the seesaw 15 are included. If the desired guidance can be performed, it may be composed of one piece or one piece.

  A column support 11 is formed integrally with the base 12 on the left side of the member insertion portion 12c in the drawing, that is, on one side of the member 30. As shown in FIG. 2, the support column 20 is inserted and attached. The strut 20 inserted into the strut receiving portion 11 is fixed to the strut receiving portion 11 by an inner end of a set screw 11b screwed into the screw hole 11a of the strut receiving portion 11.

  In order to fix the column 20 to the member 30 using the column clamp 10, first, the entire column clamp 10 is carried to a place where the column 20 of the member 30 is to be erected and formed on the base 12. The upper end of the member 30 is inserted into the inserted member insertion portion 12c, and the column clamp 10 is positioned. In this case, the wedge 13 rises to the state shown in FIG. 4, that is, the uppermost end, and the pressing surface 13c, that is, the left side surface in FIG. 4 completely opens the member insertion portion 12c. In relation to this, the seesaw 15 swings in the clockwise direction, one end 15b of the seesaw 15 receives the lower end of the wedge 13, and the other end 15c of the seesaw 15 receives the lower end of the opening member 14 described later. I accept. In other words, the opening member 14 is in a state of being lowered to the lowest end.

In the following, the expression that one end 15b of the seesaw 15 is "related" to the wedge 13 or the other end 15c of the seesaw 15 is "related" to the opening member 14 will appear. This "related" This means that they are “related to each other and interlocked” , and specifically “abut or connect”. In other words, the wedge 13 and the lower end of the opening member 14 are received with respect to the one end 15b and the other end 15c of the seesaw 15 in the case of the embodiments shown in FIGS. 1 to 5, 7 and 8. In other words, in FIG. 6, since they are “rotatably connected” and have different aspects , these cases will be collectively referred to below. Sometimes expressed as “related”.

  The post clamp 10 positioned at the upper end of the member 30 must be fixed to the member 30. For this purpose, the upper end of the wedge 13, that is, the striking portion 13a shown in FIG. Strike with or strike. If it does so, naturally the wedge 13 is movably assembled | attached to the assembly | attachment part 12a of the base 12, and while being pushed down below, the one end 15b of the seesaw 15 is also pushed down by the lower end. At this time, the wedge 13 is to press one side of the member 30 toward the abutting portion 12b provided on the base 12, so that the pressing surface 13c of the wedge 13 is shown in FIG. As shown, the upper end of the member 30 is pressed against the contact portion 12 b of the base 12. As a result, the column clamp 10 is firmly fixed to the upper end of the member 30.

By the way, the wedge 13 that has been lowered is associated with an opening member 14 via a seesaw 15 , that is, is “abutted or connected”, and the opening member 14 is attached to the wedge 13 to move relative to the wedge 13. Since it is assembled to 12a, for example, as shown in FIG. 5, the lower end of the opening member 14 is pushed up by the other end 15c of the seesaw 15, and the opening member 14 moves upward, that is, moves relative to the wedge 13 that falls. . Here, the “relative movement” between the wedge 13 and the opening member 14 means that even when the wedge 13 and the opening member 14 are arranged adjacent to each other as shown in FIGS. When the wedge 13 and the opening member 14 are arranged in parallel to each other as shown in FIG. 8, it means that one of them moves down and the other moves up through the seesaw 15.

In other words, the wedge 13 that moves “relatively” and the opening member 14 are formed in a plate shape and arranged adjacent to each other, as shown in FIGS. 8, in each case, the lower ends thereof are “related ” to each other by one end 15b and the other end 15c of the seesaw 15 , that is, “abut or connect”. It's a good match. In the case shown in FIGS. 4 and 5, the thickness of the portion assembled to the base 12 can be reduced as shown in FIGS. 2 and 3, whereas in the case shown in FIGS. As described above, the length of the portion assembled to the base portion 12 can be shortened.

  As described above, for the column clamp 10 fixed to the upper end of the member 30, as shown by the phantom line in FIG. 2, the lower end of the column 20 is inserted into the column receiving portion 11 and the set screw 11b is screwed. As a result, the column 20 can be fixed to the member 30 as a result. The support column 20 is generally composed of a metal round pipe. The support column 11 is fixed to the support column receiving part 11 by screwing a set screw 11b. Even the support 20 can be sufficiently fixed to the member 30 within a certain range.

Now, when the case where the said support | pillar clamp 10 is removed from the member 30 is demonstrated, as shown in FIG. 5, the strike part 14a of the open | release member 14 which is moving up is the same side as the strike part 13a of the wedge 13 ( since in the embodiment is directed upward), hit the strike portion 14a from the same side as that beat striking portion 13a of the wedge 13 with a tool such as a wafer Nma. Then, the opening member 14 is pushed down, and at the same time, the lower part of the wedge 13 related to the one end 15b of the seesaw 15 is pushed up. As a result, the pressing surface 13c pressing one side of the member 30 toward the abutting portion 12b provided on the base 12 retreats in the right direction as shown in FIG. The member insertion part 12c in the wedge 13 base 12 is opened. As a result, the column clamp 10 can be easily removed from the upper end of the member 30. During this operation, the support column 20 may be removed from the support column clamp 10 or may remain attached.

  In other words, when the striking portion 14 a of the opening member 14 is pressed from the same direction as the pressing direction of the striking portion 13 a of the wedge 13, the strut clamp 10 moves the wedge 13 via the seesaw 15, and the wedge 13 Since the fixing to the member 30 is released, this releasing operation can be performed by the same position and method as the fixing operation.

  Therefore, the column clamp 10 according to the first aspect of the present invention can be used easily by fixing the column 20 to the member 30 and releasing it from only one of the tools.

Moreover, in order to solve the said subject, the means which invention which concerns on Claim 2 took about the support | pillar clamp 10 for temporary installation of the said Claim 1,
“The movement of the wedge 13 with respect to the attachment portion 12a of the base 12 is formed in the wedge 13 and is attached to the elongated hole 13b that is inclined from one to the other toward the contact portion 12b. It was done by engaging the guide pin 16 fixed to 12a "
It is.

  In the column clamp 10 according to the second aspect, as shown in FIG. 4 and FIG. 5, or FIG. 7 and FIG. 8, the long hole 13b that is inclined from the one side to the other side toward the contact portion 12b as shown in FIG. Since the guide pin 16 fixed to the assembly portion 12a is engaged with the elongated hole 13b, the range of movement of the wedge 13 relative to the base portion 12 is limited, and the fixing by the wedge 13 is performed. And the release of this fixation can always be performed in the same state, so that both operations are ensured.

  In the wedge 13 shown in FIG. 4 and FIG. 5 or FIG. 7 and FIG. 8, two elongated holes 13b are formed parallel to each other, and one guide pin 16 is engaged in each elongated hole 13b. Thus, the fixing by the wedge 13 and the releasing of the fixing can be always performed in the same state, but the present invention is not limited to this. For example, as shown in FIG. 6, only one elongated hole 13b is formed in the wedge 13, and a guide pin 16 whose engaging surface is inclined with respect to the elongated hole 13b is formed in the elongated hole 13b. Alternatively, it may be engaged, or conversely, three or more elongated holes 13b with which the guide pins 16 are engaged may be formed.

  Therefore, the column clamp 10 according to the second aspect exhibits the same function as that of the first aspect, and can be fixed and released by the wedge 13 in the same state at all times.

Furthermore, in order to solve the said subject, the means which invention which concerns on Claim 3 took about the support | pillar clamp 10 for temporary installation of the said Claim 1 or Claim 2,
“The size of the one end 15b and the pivot 15a of the seesaw 15 is smaller than the dimension of the other end 15c and the pivot 15a”
It is.

  In the column clamp 10 according to claim 3, for example, as shown in FIG. 4, the size of the one end 15b and the pivot 15a of the seesaw 15 is smaller than the dimension of the other end 15c and the pivot 15a. "The principle of lion" can be applied.

  That is, by making the size of the one end 15b and the pivot 15a of the seesaw 15 smaller than the size of the other end 15c and the pivot 15a, the force that pushes down the opening member 14 is applied to the wedge 13 via the seesaw 15. When making it related, it can be hung on the wedge 13 while being enlarged by the “principle principle”. The wedge 13 fixing the column clamp 10 to the upper end of the member 30 may have a large fixing force due to excessively applied pressing force or rust due to rain or the like. If the “principle principle” can be applied to the seesaw 15 like the column clamp 10, the wedge 13 can be easily released in such a case.

  Therefore, the column clamp 10 according to the third aspect exhibits the same function as that of the first or second aspect, and can more easily release the wedge 13.

As described above, in the present invention,

The handrail attachment bracket shown by patent document 1 is shown, (a) is a front view, (b) is a longitudinal cross-sectional view, (c) is a top view.

  Next, the invention according to each claim configured as described above will be described with respect to the column clamp 10 which is the embodiment shown in the drawings. The column clamp 10 of this embodiment is shown in FIGS. Since there are the first embodiment and the second embodiment shown in FIGS. 7 and 8, the column clamp 10 according to each embodiment will be described in order below.

(First embodiment)
1 to 5 show a column clamp 10 according to a first embodiment of the present invention. This column clamp 10 attaches a column 20 to a member 30 installed at a construction site. Here, the member 30 to which the column clamp 10 will be attached will be described. The member 30 corresponds to various members such as “sheet pile”, “H steel”, “casing” for excavating the counterbore. To do. In other words, it is this member 30 that is attached to the column 20 described later.

  Such a member 30 includes a “fence”, “ladder”, “scaffold”, to protect the construction site, to ensure the safety of workers, and to let passersby know that this is the construction site. Various temporary materials such as “signboards” or “roofs” need to be fixed. These “fences”, “ladders”, “scaffolds”, “signboards”, “roofs” and the like are usually provided with support columns 20, and these “fences” are attached by attaching the support columns 20 to the members 30. "," Ladder "," scaffolding "," signboard ", or" roof "are completed. In this case, a metal round pipe or a square pipe is generally used as the support 20 and the diameter is also different.

As shown in FIGS. 1 to 5, the column clamp 10 according to the first embodiment is mainly disposed on one side of the member 30 and the column receiving unit 11 to which the column 20 is attached. The member 30 is movably assembled to the base 12 that is integrated with the column support 11 and the assembly 12 a extends to the other side of the member 30 and the assembly 12 a of the base 12. A wedge 13 that presses one side of the blade toward a contact portion 12b provided on the base 12, a release member 14 assembled to the assembly 12a to move relative to the wedge 13, and the release member mounted on pivot 15a on the attaching portions 12a which is located between the 14 and the wedge 13, abuts or is connected to the wedge 13 at one end 15b, it is brought into contact or connected to the other end 15c to opening member 14 seesaw 15 and comprising That.

  As shown in FIGS. 1 and 2, the column receiving part 11 in the present embodiment is formed in a square pipe shape with metal, and as shown in an imaginary line in FIG. 2, A part of the column 20 is inserted and fixed. In order to fix the column 20, a plurality of screw holes 11a are formed in the column receiving portion 11, and set screws 11b can be screwed into the screw holes 11a. Of course, the inner end of each set screw 11b abuts on the surface of the support column 20 and fixes it to the support column receiving portion 11, but even if the diameter of the support column 20 is different, It goes without saying that the struts 20 of any diameter can be dealt with by adjusting the screwing amount.

  As shown in FIGS. 2 and 3, the two plate-like base portions 12 are provided to the support column 11 as described above via the first guide 17, the second guide 18, and the spacer 19. Integrated with a certain gap formed. The reason why the two bases 12 are provided is that the wedge 13 and the long hole 13b, which will be described later, can be easily incorporated in the meantime, and the overall thickness can be reduced. Of course, the base 12 may be a single plate or a block as long as the wedge 13 and the long hole 13b can be assembled in a movable manner.

  As shown in FIG. 4, each base portion 12 has a member insertion portion 12c into which a member 30 to which the column clamp 10 is to be attached is inserted, an assembly portion 12a on the right side of the member insertion portion 12c, A contact portion 12b on the left side of the member insertion portion 12c is formed. The member insertion portion 12c is closed at the upper end in FIG. 4 so that the upper end of the member 30 can be abutted and stopped. The assembling portion 12a is a portion for assembling the wedge 13 and the opening member 14 described later, and is also a portion to which a guide pin 16, a first guide 17, a second guide 18 and the like described later are fixed.

  As shown in FIG. 4, the wedge 13 assembled to the assembly portion 12 a of the base portion 12 is a plate-shaped member whose upper end in the drawing is a striking portion 13 a, and a plurality of elongated holes 13 b are formed in the middle thereof. Is formed. These elongate holes 13b are inclined at the lower part toward the member insertion portion 12c of the base portion 12, and a guide pin 16 fixed between the both base portions 12 is engaged in the elongate hole 13b. Is. Further, the left side surface of the wedge 13 shown in the figure is a pressing surface 13c that presses the other (right side) surface of the member 30 inserted into the member insertion portion 12c. The inclined surface 13d has the same inclination angle as each elongated hole 13b.

  A cam projection 17a of a first guide 17 interposed between the base portions 12 is brought into contact with the inclined surface 13d of the wedge 13, and the first guide 17 guides the inclined surface 13d, whereby The same function as that of the elongated hole 13b and the guide pin 16 engaged therewith, that is, when the wedge 13 moves downward relative to the base portion 12, the pressing surface 13c of the wedge 13 faces the member insertion portion 12c. The function to perform is demonstrated.

  In the wedge 13 shown in FIG. 4, two elongated holes 13b parallel to each other are formed, and the guide pin 16 is engaged in each of the elongated holes 13b, so that the wedge 13 is moved in the vertical direction as a purpose. However, the present invention is not limited to this, and the movement in the vertical direction can be performed in a constant direction by the example shown in FIG.

  As in the case described above, the long hole 13b shown in FIG. 6 is inclined so as to be directed toward the member insertion portion 12c of the base portion 12, but only one is formed. And the shape of the guide pin 16 engaged in this long hole 13b is made long in the same direction as the inclination direction of the long hole 13b, so that the wedge 13 is directed to the member insertion part 12c of the base 12. It is what you are doing.

  On the other hand, the opening member 14 is a single plate-shaped member interposed between the first guide 17 and the second guide 18 that forms a predetermined gap between the base portions 12 and fixes the base portions 12. In the middle, a long hole 14b with which the guide pin 16 is engaged is formed, and a striking portion 14a is formed at the upper end. The opening member 14 is guided by the first guide 17 and the second guide 18 so as to be moved in the vertical direction on both side surfaces thereof, and is also guided by the elongated hole 14b with which the guide pin 16 is engaged. Therefore, it can move in a vertical direction in a stable state.

  Now, the lower ends of the opening member 14 and the wedge 13 are respectively associated with the other end 15c and one end 15b of the seesaw 15, as shown in FIG. The seesaw 15 is swingably attached to each base 12 by a pivot 15a, and has one end 15b engaged with the lower end of the wedge 13 and the other end 15c engaged with the lower end of the opening member 14. It is. Of course, the one end 15b and the other end 15c are rounded in order to be related to the wedge 13 and the opening member 14 even when the seesaw 15 swings.

  In the seesaw 15 in the first embodiment, for example, as shown in FIG. 4, the dimensions of the one end 15b and the pivot 15a of the seesaw 15 are smaller than the dimension of the other end 15c and the pivot 15a. Thus, the “principle principle” can be applied. That is, by setting the seesaw 15 in this way, when the force that pushes down the opening member 14 is related to the wedge 13 via the seesaw 15, it can be applied to the wedge 13 while being enlarged by the “principle principle”. It is doing so. The wedge 13 fixing the column clamp 10 to the upper end of the member 30 may have a large fixing force due to excessive pressing force or rust caused by rain or the like. This is because the wedge 13 can be easily released in such a case if the “principle of” is applicable.

  The shape of the seesaw 15 is not necessarily required to be related to the wedge 13 or the opening member 14 as shown in FIG. For example, like the seesaw 15 shown in FIG. 6, at one end 15 b and the other end 15 c, the wedge 13 and the other end 15 c may be rotatably connected to the lower end of the wedge 13 and the other end 15 c by a pin or the like.

  As shown in FIGS. 1 to 3, the first guide 17 and the second guide 18 freely move the wedge 13, the opening member 14, and the seesaw 15 between the two plate-like base portions 12. This is used for forming a space or a gap for securing the gap and for integrating the base portions 12. Further, the hatched member located at the leftmost end in FIG. 4, that is, the spacer 19, makes the dimension between the base portions 12 constant and fixed.

  In particular, as shown in FIG. 4, the left side surface of the first guide 17 is an inclined surface having the same angle as the inclined surface 13 d of the wedge 13, and toward the wedge 13 side in the middle of the inclined surface. A cam projection 17a is formed. The cam protrusion 17a guides the inclined surface 13d of the wedge 13 that moves up and down by point contact, and also prevents the so-called "biting" of the wedge 13. Further, the right side of the first guide 17 shown in the figure is a vertical guide surface 17b, and this time reliably guides the movement of the opening member 14 in the vertical direction. Of course, a vertical guide surface for guiding the movement of the opening member 14 in the vertical direction is also formed on the second guide 18 side.

  As shown in FIG. 4, the illustrated left side surface of the second guide 18 is formed in a straight line in the vertical direction in the same manner as the illustrated right side surface of the first guide 17. In the space formed by the second guide 18, the opening member 14 is guided in the vertical direction.

(Second embodiment)
7 and 8 show a column clamp 10 according to a second embodiment of the present invention. The difference of the second embodiment from the first embodiment is that the plate-like wedge 13 is different from the first embodiment. That is, the opening member 14 is disposed so as to overlap the thickness direction, and the direction of the seesaw 15 is rotated by 90 degrees with respect to the case of the first embodiment. Therefore, when the side surface of the column clamp 10 according to the second embodiment is viewed, as shown in FIG. 7, both the wedge 13 and the opening member 14 are overlapped, and the pivot 15a of the seesaw 15 is lateral. It is located in the direction.

  When the wedge 13 and the opening member 14 are overlapped when viewed from the side surface of the column clamp 10, the width of each base portion 12 to which the wedge 13 and the opening member 14 are to be assembled is shortened. As can be seen from a comparison between FIG. 7A and FIG. 7A, this means that the overall size of the column clamp 10 can be reduced.
