Description

  The present invention relates to a scaffolding skirting board used for securing safety to both sides of a tread erected on a constructed building scaffold.

  Conventionally, when forming a scaffold for building such as a building, it is customary to install a scaffolding tread in a horizontal state between each of the building frames facing each other with a predetermined number of intervals. It is. By the way, a gap-like space is formed on both sides of the scaffolding tread thus constructed, and there is a danger that an operator's foot slips into the space to cause injury. In addition to this, a situation may occur in which tools, parts, and the like placed on the tread board are unexpectedly dropped.

  As a conventional technique for solving such a problem, it is customary to employ a skirting board for mounting in a standing state on both sides of the tread board. And as the said baseboard, what comprised the board-like independent member, ie, the enclosure board-shaped member formed separately from the tread board, to a building frame (for example, refer patent document 1). is there. And there are those that are attached in contact with the side edges of the treads and those that are fixed to the building frame side.

  Further, there is a structure in which baseboards are connected in a undulating manner to the side edge of the tread (see, for example, Patent Document 2).

JP 2006-169902 A JP 2003-064867 A

  In the case of the base plate, which is a plate-like independent member as described above, not only is the installation work complicated, but when the construction scaffolding is high, the installation work has to be dangerous. .

  Furthermore, if the baseboard is constructed so that it can be raised and lowered continuously with respect to the side edges of the treads as described above, the ease and safety of assembling the baseboard can be ensured, When a tread is installed, there is a space (gap) between the side of the building frame and the side edge of the tread. Therefore, if the baseboard is connected to the side edge of the tread, the space is wasted As a result, there is a limitation that the work space is only on the tread.

  In the present invention, the skirting board itself is attached to the building frame side, and the gap portion formed between the building frame and the tread board is flush with the tread board by tilting the cover board provided to be raised and lowered on the base board side. Therefore, the present invention provides a new skirting board which can be used as a general work surface and solves the conventional problems as described above.

The present invention has a structure as described in claim 1 , that is, a skirting board main body 1 for being attached to be positioned near a side edge of a tread B installed on a building frame A assembled in a required form, A horizontal state in which the cover plate 5 for covering the gap formed between the side edge portion of the step board B and the building frame A is tilted to the side of the step board B from the vertical state so as to overlap the baseboard body 1 In order to enable such conversion, it is attached to the lower end portion of the baseboard body 1 so as to be able to be raised and lowered via a pivotal support N provided in a required number in a required number, and the configuration of the pivotal support N The bottom edge M of the skirting board body 1 is formed by a bottom plate-like horizontal plate portion 1b having a required width and projecting inward, and a rising piece 1c) that rises perpendicularly from the tip of the bottom plate 1c). On the lower edge of the plate 5 is a fold that can be placed on the bottom plate-like horizontal plate portion 1b of the baseboard body 1 The piece portion 5a is formed by bending at a right angle, and a guide slit hole 5b having an L shape is formed at the corner portion formed by bending at a right angle, and the slit hole 5b is formed with respect to the slit hole 5b. Since the pivot 6 for loosely fitting is horizontally installed at a required position of the lower edge portion M of the baseboard body 1, the baseboard for serving as an edge side wall with respect to the installed tread B At the same time as the use, the gap between the side edge of the tread board B and the building frame A that is formed along with the erection can be closed via the cover plate 5. Therefore, the safety of the worker on the tread B and the fear that a tool, parts, etc. put on the tread will fall from the gap and cause a serious accident are well resolved. It becomes. Since the baseboard body 1 and the cover plate 5 are configured so as to be undulated so that they are in a folded state in a folded state, the space rationality in managing and transporting the baseboard body 1 Thus, the same effect as in the case of claim 1 is obtained.

Furthermore, the configuration of the pivot portion N is configured as described above, so that the undulation operation of the cover plate 5 is performed extremely stably, and the operational effect based on the configuration of claim 2 described below is obtained. This is achieved on the basis of the adoption of such a pivot N.

The present invention is configured as described in claim 2 , that is, dimensionally set so that the height of the rising piece 1 c that forms the lower edge M of the baseboard body 1 substantially matches the height of the erection step board B. In addition, when the dimensional setting of the bent piece 5a formed at the lower end of the cover plate 5 is rotated in the horizontal state, the cover plate 5 becomes the corner of the bent piece 5a. It is received at the upper end of the rising piece 1c in the corner position portion, and the edge portion of the bent piece portion 5a is dimensioned so that the baseboard body 1 is slightly floated from the bottom plate-like horizontal plate portion 1b. Since the setting is made, the inclining operation is performed smoothly so that the cover plate 5 is in a horizontal state with the tread B.

  At the same time, the cover plate 5 is received by the lower end edge M of the baseboard body 1 over its entire length. Therefore, for example, compared to a case where it depends on partial support (erection support) such as near both ends, the support form is extremely excellent in strength, and a large load is applied to the cover plate 5. This also eliminates the risk of deformation such as warping. In other words, since the upper side of the cover plate 5 can have the same strength as that of the step board B, by including the cover plate 5, there is an effect such as enlargement of a working space by an operator. It will be.

The present invention is configured as described in claim 3 , that is, dimensionally set so that the height of the rising piece 1 c forming the lower edge M of the baseboard body 1 substantially matches the height of the erection step board B. When the cover plate 5 in the vertical state superimposed on the inner surface of the skirting board main body 1 is rotated and transferred to the horizontal state, the bent piece 5a has a bent piece portion 5a on the inner surface of the skirting board main body 1. The load applied to the cover plate 5 can also be received at the contact portion between the bent piece 5a and the inner surface of the skirting board body 1 because it is configured to be received at the upper end of the rising piece 1c while being in contact with Become. Therefore, as shown in FIG. 8, there is a problem that the bottom plate-like horizontal plate portion 1b connected to the rising piece 1c is warped based on the load applied to the cover plate 5 being applied only to the rising piece 1c. And the occurrence of bending of the cover plate 5 due to the overlap between the line end edge of the cover plate 5 and the erection tread B based on the occurrence of the warp, and the worst case dropout based on this, This will prevent such problems.

The invention as described in claim 4 configuration, that is, on both sides of a fold pieces 5a which are at right angles to form the edge of the blocking plate 5, when was transferred rotate the blocking plate 5 in a horizontal state In addition, the stepped bent portion 5c for the spacer is formed so that the front end portion is in contact with the inner surface of the baseboard body 1 and the rear end portion is in contact with the rising piece 1c formed on the baseboard body 1. Then, based on the presence of the stepped bent portion 5c for the spacer, when the cover plate 5 is tilted horizontally, the bent piece portion 5a of the cover plate 5 comes into contact with the inner surface of the baseboard body 1. Since it is configured to be pushed, a sliding action is automatically achieved such that the cover plate 5 comes into contact with the inner surface of the baseboard body 1. At the same time, stabilization in such a state is achieved, and the situation where unexpected sliding of the cover plate 5 with respect to the tread B, that is, occurrence of sliding to the state shown in FIG. The stabilization of the cover plate 5 is achieved.

The present invention has the structure as described in claim 5 , that is, mounting posts 2, 3 are fixed to both ends of the baseboard body 1, and a quarter of a perfect circle is formed at the lower ends of the posts 2, 3. Arc-shaped edges 2a and 3a having an arc shape are formed, and the dimensions between the mounting columns 2 and 3 are made to match the opposing dimensions provided for the building frame A constructed as a construction scaffold to construct the tread B. As a result, the arc-shaped edges 2a and 3a formed at the lower end of the building frame A are configured to be placed on the half circle of the horizontal beam a having the circular cross section of the building frame A. When installing the baseboard body 1 continuously (in a straight line) with respect to the horizontal rail a, two mounting columns 2 and 3 that are opposite baseboards are located on one horizontal rail a. However, based on the above-mentioned "formation of arc-shaped edges 2a and 3a that form a quarter of a circular arc of a perfect circle", both struts do not overlap, In other words, it is possible to mount the support post for installation on one baseboard body in a straight line without interfering with the installation of the support post for installation of the other baseboard body. Is done.

The present invention has the structure as described in claim 6 , that is, as a mounting means for the building frame A constituting the construction scaffold, on the back side near the upper end of each of the mounting posts 2 and 3, and on the upper end is the baseboard body 1. An upper end flange 4a is formed to be secured to the upper edge of the frame, and a lower end flange 4b is folded at the lower end so as to be freely held by the column b of the building frame A. The bent fixing hook 4 is mounted so as to be movable up and down and rotatable. The fixing hook 4 can be freely rotated in a state in which the hook is pulled up, and the lower end flange 4b is held to the column b of the building frame A. The upper end collar 4a is stabilized by being dropped into the upper end edge of the skirting board body 1 by being pulled down after being rotated so as to be held. Since it is configured so that the holding can be fixed, Attaching the scaffolding baseboard to the building frame is just a latch, such as lifting, rotating, and lowering the fixing hook 4 in a state where the columns 2 and 3 are placed on the horizontal rail a of the building frame. It is achieved simply by performing an operation. Therefore, compared to the case where tightening work using a tool is required, the mounting purpose is achieved very easily. Will contribute.

  1 and 2 show a scaffolding skirting board according to the present invention. FIG. 1 shows the scaffolding skirting board according to the present invention in a folded state, and FIG. 2 shows an opening in an L shape. This represents the state of use (use state). And, as shown in FIG. 6, the baseboard according to the present invention is attached to the building frame A assembled in the required form in a state where it is erected on the side edge side portion of the tread B that is installed. It is characterized by being configured so as to be able to cover a gap formed between the side edge of the tread B and the building frame A while playing a role as a tree.

  In the figure, reference numeral 1 denotes a skirting board main body, which is mainly formed of a metal plate material, and mounting posts 2 and 3 are fixed to both ends thereof. Reference numerals 2a and 3a denote arc-shaped edges (an arc-shaped edge that is a quarter of a perfect circle) formed at the lower ends of the support columns 2 and 3, and are formed of horizontal bars a (round bars) of the building frame A. ) Is intended to stabilize the mounting. (See Figure 6)

  By the way, although it is a mounting form of the arc-shaped edges 2a and 3a, it is important that this is configured so as not to exceed the upper half of the cross-sectional shape of the cross beam a having a circular cross section (perfect circle). This is because the horizontal rail a is constructed by continuously merging the product of the present invention (baseboard body) in a straight line, that is, two horizontal products a are constructed on one horizontal beam a. Because of the straight line relationship, it is important that the mounting of the support for the construction of the one baseboard body does not interfere with the placement of the support for the construction of the other baseboard body. . (For this purpose, the arc-shaped edges 2a and 3a are formed as arc-shaped edges of a quarter of a perfect circle)

  And the dimension between the above-mentioned mounting support pillars 2 and 3 is made to correspond to the opposing dimension of the building frame A assembled as a construction scaffold, and the arc-shaped edges 2a and 3a formed at the lower end thereof are the building frame A. It is comprised so that it may be mounted on the semicircle of the horizontal crosspiece a provided with the circular cross section of this. In addition, a tread B is installed between the horizontal beams a and a of the opposing building frames A and A. Therefore, the mounting columns 2 and 3 are placed on the horizontal beams a and a. Therefore, the skirting board main body 1 is constructed in a state along the side edge of the tread B. (See FIGS. 5 to 7)

  Reference numeral 4 denotes a fixing hook which is attached to the back side near the upper end of each of the mounting posts 2 and 3 so as to be lifted and rotated freely. The upper end is fixed to the upper edge of the baseboard body 1 for stabilization. The upper end flange 4a is formed, and at the lower end, a lower end flange 4b is formed so that it can be hooked and held with respect to the column b of the building frame A. (See FIG. 6) The fixing hook 4 can be freely rotated when the hook 4 is pulled up, and the lower end flange 4b is held by the column b of the building frame A. After being rotated, the upper end flange 4a is stabilized by being dropped into the upper end edge of the skirting board body 1 by being pulled down in this state. Thereby, it is comprised so that the said holding | maintenance can be fixed. (State shown in FIGS. 5 and 6). Reference numeral 4c denotes a support fitting for supporting the fixing hook 4 so as to be movable up and down and rotatable.

  By the way, it is the upper end edge 1a of the baseboard body 1 described above, and this is a strength as a plate material by folding it into a right-angled hook shape (by bending the horizontal top surface and the folded down one edge). The stabilization is ensured by increasing and dropping the above-described upper end flange 4a while sandwiching the upper end edge 1a.

  Furthermore, although it is the board surface of the said baseboard main body 1, this is the intensity | strength as a board | plate material by press-molding appropriate unevenness | corrugation (in the example of illustration, the stepped uneven surface is formed). It is configured to improve the performance.

  And it is the lower end edge part M of the said baseboard main body 1, This is the bottom plate-shaped horizontal board part 1b which has required width and protrudes inward, and the standing piece 1c which stands | starts up from the front-end | tip at right angle of required height. It consists of As a whole, it has a right-angled hook shape, and the lower edge M has a reinforcing action on the lower edge of the baseboard body 1 and, at the same time, is a undulating attachment member for the cover plate 5 described below. It is configured to function.

  Reference numeral 5 denotes a cover plate, which is attached to the lower edge of the skirting board main body 1 so as to be raised and lowered in the form described later. And the said board 5 is made into a folded state in the vertical state (a state overlapped with the skirting board main body 1), and when this is tilted horizontally, a step board whose top end portion is erected on the building frame A By overlapping the side edge portion of B by the required width (overlap width W shown in FIG. 5), a gap formed between the side edge portion of the tread B and the building frame A is covered. In addition, the safety | security improvement is achieved by press-molding the uneven | corrugated pattern for plate | board surface reinforcement | strengthening and anti-slip | skid on the surface of the said cover board 5. FIG.

  Although the above-described cover plate 5 is attached, the lower end edge portion of the cover plate 5 is located at a required position with respect to the lower end edge portion M of the skirting board main body 1 (in the illustrated embodiment, near the front and rear ends. Three places with the central part) are connected via a pivotal support N provided so that they can fall down freely.

Although it is the above-mentioned pivot part N, this has the following structures.
As shown in FIG. 3, a folding piece 5a that can be placed on the bottom plate-like horizontal plate 1b constituting the lower edge M of the baseboard body 1 is folded at a right angle at the lower edge of the cover plate 5. Bending. Then, a guide slit hole 5b having an L shape is opened at a corner portion of the formation portion. Then, a pivot 6 for loosely fitting (relaxing through) the slit hole 5b is installed horizontally at a required portion of the lower edge portion M of the baseboard body 1.

  As shown in FIG. 3, the pivot portion N formed as described above has the L-shaped pivot 6 when the cover plate 5 is overlaid on the inner surface of the skirting board main body 1, that is, in the folded state. The folding state is allowed by being located in the slit portion provided on the plate surface near the lower end of the cover plate 5 of the guide slit hole 5b. And when the said cover board 5 is fallen so that it may become a horizontal state, the said pivot 6 is from the part drilled in the bending piece part 5a of the slit hole 5b, ie, the part loosely fitted in the folded state. As shown in FIG. 4, relative movement is performed at a portion positioned at a right angle. The folding of the cover plate 5 is performed based on the reverse operation described above.

  The pivot portion N has the above-described configuration, and based on the above-described operation, the above-described undulation operation of the cover plate 5 with respect to the baseboard body 1 is allowed. And the formation location of the said pivot part N may be provided in several appropriate places other than three places as shown in the figure.

  By the way, when the cover plate 5 is in a lying state as described above, it is important that the cover plate 5 overlaps the step plate B installed on the building frame in a horizontal state. For this purpose, it is necessary to set dimensions so that the height of the rising piece 1c forming the lower edge M of the baseboard body 1 matches the height of the erection step board B.

  Furthermore, when the size of the folded piece portion 5a formed at the lower end of the cover plate 5 is rotated in the horizontal state, the bent corner portion of the bent piece portion 5a becomes the baseboard body 1 By performing the dimensional setting so as to be placed on the rising piece 1c of the gawa, the cover plate 5 in the horizontal state is stabilized on the tip side based on polymerization with respect to the upper surface of the tread B, and On the base end side, the bent corner portion is stabilized over the entire length based on the placement (receiving) of the baseboard body 1 on the edge of the rising piece 1c of the skirt. Therefore, the gap blockage by the cover plate 5 is performed in an extremely stable state in terms of strength.

  In other words, as shown in FIGS. 2 and 4, the size of the rising piece 1c of the baseboard body 1 is set so as to be longer than the size of the bent piece 5a of the cover plate 5, as shown in FIGS. Since the plate 5 is placed in the support state by the lower end edge M (on the end edge of the rising piece 1c) of the skirting board main body 1 over its entire length, this is partially supported by, for example, both ends (erection support) ) And a support form that is extremely superior in strength, and at the same time, based on the above dimensional setting, the undulation movement of the cover plate 5 has a lower edge M of the baseboard body 1. This is achieved without causing rotational inhibition such as being caught inside.

  FIG. 7 shows the entire constructed scaffold. In the illustrated embodiment, the scaffolding skirting board according to the present invention is provided on both the left and right sides of the step board B installed in two rows. By attaching to the side edge portion, safety of workers on the tread is ensured.

  In the case of the embodiment as described above, as shown in FIG. 8, since all the load applied on the cover plate 5 is received at the upper end of the rising piece 1c, the bottom plate shape connected to the rising piece 1c is based on the principle of leverage. When a situation such as warping the horizontal flat plate portion 1b occurs, the cover plate 5 tilts based on the occurrence of the warp, and the overlapping portion with respect to the tread plate B is displaced. In an extreme case, the cover plate 5 It is assumed that it is bent and comes off from the tread B. Of course, this is unlikely to occur in normal use. For example, when a load more than expected is applied to the cover plate 5, or when the constituting plate material is thinner than usual. It is assumed.

  The second embodiment shown in FIGS. 9 to 12 is a solution that solves the problem based on the above assumption and further improves the strength.

  That is, in the second embodiment, as shown in FIG. 10, when the cover plate 5 in the vertical state superposed on the inner surface of the baseboard body 1 is transferred to the horizontal state and rotated as shown in FIG. The cover plate 5 is configured to be received by the upper end of the rising piece 1c in a state where the bent piece portion 5a is in contact with the inner surface of the baseboard body 1.

  As a result, the cover plate 5 in the horizontal state is received at the upper end of the rising piece 1c in a state where the bent piece portion 5a is in contact with the inner surface of the skirting board main body 1. The stability based on the contact with the inner surface is achieved, and therefore the overloading property on the rising piece 1c is alleviated. At the same time, since the cover plate 5 is prevented from moving in the horizontal direction, the worry that the overlapped portion with respect to the tread plate B is displaced and will be detached from this will be eliminated.

  11 and 12 show a configuration for stabilizing the folded piece 5a of the cover plate 5 in contact with the inner surface of the skirting board main body 1. FIG. That is, in the case of the second embodiment, as shown in FIG. 12, stepped bent portions 5c for spacers are integrally formed on both ends of the cover plate 5 based on press molding or the like. As shown in FIG. 11, when the spacer is folded horizontally, the stepped bent portion 5c for the spacer enters between the inner surface of the baseboard body 1 and the rising piece 1c and serves as a spacer. is there.

Based on the adoption of such a configuration (based on the presence of the spacer-shaped bent portion 5c), the cover plate 5 is prevented from moving in the horizontal direction, in other words, the bent piece of the cover plate 5 is folded. The portion 5a is configured to be kept in contact with the inner surface of the baseboard body 1.

  In addition, although it is a location where the stepped bent portion 5c for the spacer described above is formed, it is usually formed at both ends of the cover plate 5. However, depending on the case, a plurality of required portions such as the center of the cover plate 5 may be provided. Or you may comprise so that it may provide in the whole.

  In the second embodiment, based on the above-described configuration, the strength problems as described above which are strongly assumed in the first embodiment are solved.
