Description

  TECHNICAL FIELD The present invention relates to a scaffold for a bracket scaffold used for a scaffold provided around a building or the like, in particular, a bracket scaffold.

  When building outer walls of buildings, etc., scaffolds are provided to surround the buildings. For example, in the city center, there are many construction sites where the space for installing the scaffolding is narrow, and bracket scaffolding is often adopted as the scaffolding. The bracket scaffold is assembled by fixing a bracket to each of a row of building sites and attaching a scaffold plate to the bracket. The bracket scaffold can be easily assembled and can save installation space as compared to a frame scaffold that is assembled on the basis of a building frame in which a steel pipe is welded in a gate shape. In the bracket scaffold, when the worker moves up and down between the floors, the worker lifts and lowers a lifting ladder, for example, a monkey lap, on a pipe provided on the building. However, when a scaffolding plate is spread on the bracket, there is no space for the operator to move up and down. Therefore, in order to secure a space for lifting and lowering the worker, it is necessary to remove the scaffolding plate every time the lifting or lowering is performed, or to provide a place where the scaffolding plate is not laid.

  Removing the once-attached scaffolding plate from the bracket is a cumbersome operation for the operator, and providing a place where the scaffolding plate is not laid increases the risk of the operator falling from the scaffolding. As a solution to such a problem, Patent Document 1 discloses a bracket scaffold tread that can be switched between a horizontal posture that can be used as a work floor and a standing posture that secures a work space. As shown in FIG. 7, the bracket scaffold tread 100 of Patent Document 1 includes a tread board main body 101 and a pair of bracket coupling portions 102, and the bracket coupling portion 102 is attached to the bracket 104 attached to the single building pipe 103. Is attached to the bracket connecting portion 102 so as to be rotatable about a horizontal axis.

  When the bracket scaffold tread 100 of Patent Document 1 is used for a bracket scaffold, it is necessary to provide a bracket 104 for attaching the bracket scaffold tread 100. In addition, when installing the bracket scaffolding tread 100, it is necessary to install the single building pipe 103 and the bracket 104 accurately in position so as to match the size of the bracket scaffolding tread 100. However, when installing a bracket scaffolding in a building site with a small open space, the installation position of the single building pipe 103 can be adjusted flexibly according to the building site, such as the space in the open space and the shape of the building. Desired. Therefore, when using the bracket scaffolding tread 100 of Patent Document 1, it is not possible to meet the requirement of flexibly adjusting the installation position of the building site single pipe 103. As described above, in the bracket scaffolding tread 100 of Patent Document 1, the interval between the adjacent building single pipes 103 must be the same as the size of the bracket scaffolding tread 100. Furthermore, when the building site single pipes 103 are installed at intervals different from the size of the bracket scaffolding tread 100 and the bracket scaffolding is assembled, the bracket scaffolding tread 100 cannot be attached to the bracket scaffolding later. In such a case, the bracket scaffold that has already been installed must be disassembled, and the bracket scaffold must be assembled again in accordance with the size of the bracket scaffold tread 100.

FIG. It is a perspective view which shows the tread board for the conventional bracket scaffold.

  Hereinafter, with reference to an accompanying drawing, an embodiment of a foot board for bracket scaffolds of the present invention is described in detail.

  The bracket scaffold tread 1 according to the present invention is used for a scaffold provided around a building or the like, particularly a bracket scaffold, when performing outer wall construction or the like of a building or the like. The bracket scaffolding is constructed of a building site S (building pipe) perpendicular to the ground of the building site, and a bracket B extending perpendicularly (horizontally) to the building site S is fixed, and cantilevered. This is a temporary structure in which the scaffolding plate SP is placed on the bracket B that extends to. In many cases, bracket scaffolds are mainly constructed in narrow spaces where frame scaffolds cannot be assembled. As shown in FIG. 1, the bracket scaffolding tread 1 of the present invention is a space formed between the scaffolding plates SP attached to the brackets B fixed to each of the pair of building sites S of such bracket scaffolding. Is used as a scaffolding plate that can open and close the space. In addition, as for the building site S, the bracket B, and the scaffolding plate SP, those having a known structure that has been conventionally used can be used.

  As shown in FIG. 1, a bracket scaffold tread 1 according to the present invention has a tread board main body 2 provided in an openable / closable manner between the scaffold boards SP, and the tread board main body 2 is hinged so as to be opened / closed. A support plate 3 to be attached and attachment means 4 for attaching the support plate 3 to a pair of building sites S are provided.

  The tread board main body 2 fills a space formed between the end portions of the pair of scaffolding boards SP, and is used as a tread board (work floor) on which the operator rides when working or walking. In the embodiment shown in FIG. 1 (hereinafter referred to as this embodiment), the tread board body 2 connects a pair of building sites S and extends in a direction perpendicular to the longitudinal direction of the building site S. A steel checker plate formed as is used. The tread board main body 2 may be anything that can fill the space formed between the pair of scaffolding plates SP and has a size and rigidity that allows an operator to get on, and has a substantially rectangular checker plate. It is not limited to this, and it may have other shapes and materials.

  As shown in FIGS. 1 and 2, the tread board main body 2 is hinged to the support plate 3 by a hinge 21 and is fixed to the support plate 3 so as to be rotatable. The tread body 2 accommodates the first position P1 where the tread body 2 can be used as a work floor (a position where the tread body 2 is in a horizontal position; a position indicated by a solid line in FIG. 5), and the tread body 2. Thus, it is configured to be openable and closable with respect to a second position P2 for securing a work space (a position where the treadle main body 2 is in a standing posture; a position indicated by a two-dot chain line in FIG. 5). That is, in the bracket scaffolding tread 1, the tread body 2 can be used as a work floor by arranging the tread body 2 at the first position P1 (see FIG. 1), and the tread body 2 is in the second position. By arranging in P2, it is possible to secure a space for the operator to work, such as when the operator moves up and down between the levels of the bracket scaffolding, and transfers building materials and the like between the levels (see FIG. 6). In the present embodiment, the tread base body 2 is hinged to the support plate 3 by a hinge 21, but the tread base body 2 is hinged to the support plate 3 so as to be openable and closable between the first and second positions P1 and P2. As long as it is connected, the means for connection is not limited to the hinge 21 shown in the figure, and other known hinge connection means can be used. The first position P1 is not limited to the illustrated horizontal position, and may be inclined from the horizontal position, as long as the tread body 2 can be used as a work floor. . Further, the second position P2 is not limited to the position in the illustrated standing posture, and may be any position as long as the work space can be secured by housing the tread body 2 and from the position in the standing posture. It does not matter if it is tilted.

  As shown in FIG. 1, the tread board main body 2 is supported by a pair of scaffolding plates SP at a first position P1 that can be used as a work floor. More specifically, as shown in FIG. 1, both ends of the tread board main body 2 are placed on the pair of scaffolding plates SP, and are partially overlapped and supported by the pair of scaffolding plates SP. Since the footboard body 2 is supported by a pair of scaffolding plates SP, the length in the direction X shown in FIG. 1 (the direction perpendicular to the longitudinal direction of the building S that connects the pair of building sites S) is as follows. What is necessary is just to be formed so that it may become longer than the space | interval between the edge parts of a pair of scaffolding board SP. Therefore, unlike the footboard body 101 of the conventional bracket footboard 100 disclosed in Patent Document 1, the length of the footboard body 2 is strictly set according to the distance between the pair of building sites S and the pair of scaffolding plates SP. There is no need to design. Therefore, compared with the conventional bracket scaffold tread 100, the bracket scaffold tread 1 of the present invention has a higher degree of design freedom. In other words, the pair of building sites S and the pair of scaffolding plates SP may be installed such that the length of the footboard body 2 in the direction X is longer than the distance between the pair of scaffolding plates SP. It is not necessary to install exactly according to the size of the. Therefore, compared with the case where the conventional bracket scaffold tread 100 is used, the use of the bracket scaffold tread 1 of the present invention increases the degree of freedom of installation of the building site S and the scaffold plate SP. That is, even if the interval between the building site S and the scaffolding plate SP is different for each construction site, the same bracket scaffolding tread 1 can be used. In the present embodiment, as shown in FIG. 1, the tread board body 2 is placed on the scaffold board SP and supported by the scaffold board SP. However, when the scaffold plate SP is hooked to the bracket B via a hook (not shown) provided at the end of the scaffold plate SP, and the upper portion of the hook is located higher than the scaffold plate SP. The tread board body 2 is placed on a hook attached to the scaffold board SP and supported on the hook. Therefore, the term “supported by the scaffold plate SP” includes support through a member such as a hook attached to the scaffold plate SP.

  As shown in FIGS. 1 and 6, the tread main body 2 is provided with a handle 22 for pulling and operating the tread main body 2 on the back surface (the surface opposite to the surface on which the operator rides) of the tread main body 2. . As will be described in detail later, the tread plate main body 2 in the second position P2 can be easily moved to the first position P1 by pulling the handle board 2 with the handle 22 (see FIG. 5). In FIG. 1 and FIG. 6, the handle 22 is shown in which only one substantially U-shaped handle is provided in the central portion of the tread board main body 2. However, the shape, position, and number are not limited as long as the tread body 2 can be pulled.

  The support plate 3 is hinged to the tread plate main body 2 and supports the tread plate main body 2. Further, the support plate 3 is attached to the pair of building sites S via the attachment means 4. In the present embodiment, as shown in FIG. 1, the support plate 3 extends in the direction X, and the length of the support plate 3 in the direction X is substantially the same as the length of the tread plate body 2 in the direction X. A flat steel plate is used. The support plate 3 is hinged to the tread plate body 2 by two hinges 21. The support plate 3 is paired by two attachment means 4 so that the surface of the support plate 3 is substantially perpendicular to the surface of the scaffold plate SP and substantially parallel to the longitudinal direction of the building site S. It is attached to the building site S. The support plate 3 may be attached to a pair of building sites S and has a size and rigidity capable of supporting the tread plate main body 2 and is not limited to the above-described embodiment, and may have other shapes and materials. You may have. Further, the support plate 3 only needs to be hinge-connected to the tread plate main body 2, and the means for the connection is not limited to the hinge 21 shown in the figure, and a known hinge connection means may be used. it can. Moreover, the support plate 3 should just be attached to a pair of building land S via the attachment means 4, and the attachment method by the attachment means 4 is not limited to the said embodiment, The direction of attaching the support plate 3 May be attached in a direction different from that of the above embodiment, or may be attached by one or more attachment means 4.

  Further, as shown in FIGS. 1 and 5, the support plate 3 includes holding means 32 that holds the tread plate main body 2 in the second position P2. By holding the tread board main body 2 at the second position P2, the work space is surely secured, and the safety of the worker is secured. In the present embodiment, a magnet is used as the holding means 32, and the tread board body 2 moved to the second position P2 is attracted to the magnet 32 and held at the second position P2. One magnet 32 is provided in the center of the elongated support plate 3 in the direction X, and one magnet 32 is provided on the surface of the support plate 3 facing the tread plate main body 2 when the tread plate main body 2 is in the second position P2. In the present embodiment, a checker plate made of a magnetic material, which is the tread plate main body 2, is attracted to the magnet 32 and held at the second position P2. Since the tread base body 2 is attracted to the magnet 32 and is held at the second position P2, it is easily held at the second position P2, and at the same time, the first position P1 and the second position P2. It is possible to easily move the tread board main body 2 between them. The magnet 32 is not limited to the embodiment described above as long as the magnet 32 can be attracted and held at the second position P2, and two or more magnets 32 may be provided or provided at other positions. It doesn't matter. Further, the holding means 32 only needs to be able to hold the tread board main body 2 at the second position P2, and other holding means such as a hook can be used in addition to the magnet.

  The attachment means 4 is a member that attaches the support plate 3 to a pair of building sites S. In this embodiment, a known clamp is used as the attachment means 4 (hereinafter referred to as the clamp 4). As shown in FIGS. 2 and 3, the clamp 4 is attached to the support plate 3 via the engagement member 41 and a rod-like engagement member 41 inserted into a through hole 31 of the support plate 3 described in detail later. A base clamp piece 42 to be attached and a rotary clamp piece 43 fixed to be rotatable relative to the base clamp piece 42 are provided. The clamp 4 is fixed to the building site S by the base clamp piece 42 and the rotary clamp piece 43 being fastened around the building site S by screwing the bolt 44 and the nut 45. The attachment means 4 should just be able to attach the support plate 3 to the building site S, and is not limited to a clamp, The other well-known attachment means can be used.

  As shown in FIG. 1, the attachment means 4 is attached to the support plate 3 so that the position thereof can be adjusted according to the distance between the pair of building sites S. Depending on the construction site where the bracket scaffolding is provided, it may be difficult to provide a pair of building sites S with a space precisely spaced according to the size of the bracket scaffolding tread 1, and the spacing between the pair of building sites S It can change depending on the site. Thus, even if the interval between the pair of building sites S varies depending on the construction site, the mounting position of the mounting means 4 on the support plate 3 can be adjusted according to the interval between the pair of building sites S. The support plate 3 can be attached to the pair of building sites S without being restricted by the position of the site S. Therefore, the bracket scaffolding tread 1 can be easily attached to the bracket scaffolding without being restricted by the position of the building site S.

  In the present embodiment, as shown in FIG. 1, the support plate 3 has a through hole 31 that extends in a direction perpendicular to the longitudinal direction of the building S, and the attachment means 4 moves in the through hole 31. It is attached so that the position can be adjusted. The attachment means 4 includes a rod-shaped engagement member 41 that is inserted through the through hole 31 and is movable in the through hole 31, and is attached to the support plate 3 by the engagement member 41 inserted through the through hole 31. Since the engaging member 41 provided in the attachment means 4 is movable in the through hole 31 along the direction in which the through hole 31 extends, the position of the attachment means 4 attached to the support plate 3 is set in the direction in which the through hole 31 extends. Can be adjusted continuously. Therefore, the attachment position of the attachment means 4 can be continuously adjusted, and the degree of freedom of position adjustment is increased. In the present embodiment, two through holes 31 are provided corresponding to the positions of the pair of building sites S. However, the through-hole 31 should just be comprised so that it may be attached to the support plate 3 so that the attachment means 4 moves and the position adjustment is possible for the inside through the perpendicular | vertical direction with respect to the longitudinal direction of the building S, Two through-holes 31 may be formed in a row, or three or more through-holes 31 may be formed, and the length in the direction in which the through-hole 31 extends is also the length of necessary position adjustment. It is appropriately selected depending on. In the present embodiment, the engaging member 41 provided in the attachment means 4 is configured to be movable in the through hole 31. However, the attachment means 4 only needs to be able to move in the through hole 31. The other member provided in may be configured to be movable in the through hole 31.

  The rod-shaped engagement member 41 is a member that is inserted into the through hole 31 and attaches the attachment means 4 to the support plate 3. 2 and 3, the engaging member 41 is inserted into the through hole 31 of the support plate 3 and the hole 42h provided in the outer wall of the base clamp piece 42 of the clamp 4 as the attaching means. One end of the engagement member 41 protrudes from the outer wall of the base clamp piece 42 toward the opposite side of the support plate 3, and the other end of the engagement member 41 protrudes from the support plate 3 toward the opposite side of the base clamp piece 42. . Both ends of the protruding engaging member 41 are crimped so that the clamp 4 can move relative to the support plate 3, and the clamp 4 is attached to the support plate 3. The clamp 4 attached to the support plate 3 in this way is moved relative to the support plate 3 by the engagement member 41 moving along the through hole 31 even after being attached to the support plate 3. The mounting position with respect to the support plate 3 can be adjusted. Furthermore, since the clamp 4 is movable relative to the support plate 3, the bracket scaffolding tread can be secured even after the clamp 4 is fixed to the pair of building S and the bracket scaffolding tread 1 is attached to the pair of building S. 1 can be moved in direction X (see FIG. 1). The engaging member 41 is only required to be able to be inserted into the through-hole 31 and attach the attachment means 4 to the support plate 3, and is not limited to the above-described embodiment. For example, other members such as bolts are used. It doesn't matter. Also, the attachment method is not limited to the above-described caulking, and other methods such as attaching the clamp 4 to the support plate 3 by screwing a nut into a bolt may be used. Furthermore, after the engagement member 41 is moved along the through hole 31 and the position of the clamp 4 with respect to the support plate 3 is adjusted, the clamp 4 can be fixed to the support plate 3 so as not to be relatively movable. In this case, after the clamp 4 is fixed to the pair of building sites S and the bracket scaffolding tread 1 is attached to the pair of building sites S, the bracket scaffolding tread 1 cannot be moved in the direction X.

  In this embodiment, as above-mentioned, the support plate 3 has the through-hole 31 for attaching the attachment means 4 to the support plate 3 so that position adjustment is possible. However, the attachment means 4 only needs to be attached to the support plate 3 so that the position can be adjusted according to the distance between the pair of building sites S. The support plate 3 can be, for example, a groove in which the attachment means 4 is engaged so that the position can be adjusted. , May have other structures.

  As described above, according to the bracket scaffolding tread 1 of the present invention, the treadboard body 2 can be used as a work floor by hinge-connecting the treadboard body 2 to the support plate 3 attached to the pair of building sites S. And a position for storing the tread body 2 and securing a work space. Moreover, the attachment means 4 for attaching the support plate 3 to the pair of building sites S is attached to the support plate 3 so that the position can be adjusted in a direction X extending in a direction perpendicular to the longitudinal direction of the pair of building sites S. The bracket scaffolding tread 1 can be attached to the pair of building sites S without being restricted by the position of S.

  Next, with reference to FIGS. 4 to 6, the operational effects of the bracket scaffolding tread 1 of the present invention will be described in detail.

In addition, about a pair of building land S2 and S3, it has shown with the dashed-two dotted line. As described above, the bracket scaffolding tread plate 1 is attached to the pair of building sites S by fixing the pair of clamps 4 attached to the support plate 3 to the pair of building sites S, respectively. Here, when the bracket scaffolding tread 1 is attached to the pair of building sites S, the interval between the pair of building sites S is not always constant. For example, when a bracket scaffold is provided in a construction site with a small open space, as shown in FIG. 4, the interval between the pair of building sites S is the interval indicated by the reference symbol L1 (a pair of building sites) due to restrictions on the installation area. It is necessary to change flexibly in accordance with the installation area and the size of the scaffolding plate SP, such as the distance between the ground S2 and the distance indicated by the symbol L2 (the distance between the pair of building sites S3). Thus, even when the distance between the pair of building sites changes, the bracket scaffolding tread 1 of the present invention can be attached to the pair of building sites corresponding to the change. Specifically, in the case of a pair of building sites S2 having a shorter interval than the pair of building sites S indicated by solid lines, before fixing the clamp 4 to the building site S2, along the through holes 31 of the support plate 3. The engagement member 41 is moved to bring the pair of clamps 4 closer to each other. Thereafter, by fixing each of the pair of clamps 4 to each of the pair of building sites S2, the bracket scaffolding tread 1 can be attached to the pair of building sites S2. Moreover, in the case of a pair of building land S3 whose space | interval is wider than a pair of building land S, before fixing the clamp 4 to the building land S3, the engaging member 41 is moved along the through-hole 31 of the support plate 3. Thus, the pair of clamps 4 are separated from each other. Thereafter, by fixing each of the pair of clamps 4 to each of the pair of building sites S3, the bracket scaffolding tread 1 can be attached to the pair of building sites S3. As described above, the bracket scaffolding tread 1 of the present invention uses the same bracket scaffolding tread 1 without being constrained by the position of the building, even when the distance between the pair of buildings changes. It can be easily attached to a pair of buildings.

  FIG. 5 shows a state in which the tread board body 2 is in a position (first position P1) that can be used as a work floor and a position (second position P2) for storing and securing a work space. . FIG. 6 shows a state in which the tread board main body 2 is in the second position P2. In the bracket scaffold tread 1 attached to the pair of building sites S, when the tread body 2 is used as a work floor, the tread body 2 is arranged at the first position P1 as shown in FIG. At this time, the footboard main body 2 is supported by a pair of scaffolding plates SP positioned below both ends of the footboard main body 2 (see FIG. 4).

  Next, when the tread base body 2 is stored to secure a work space, the tread base body 2 at the first position P1 is lifted to the second position P2, as shown in FIG. Then, the checker plate which is the tread base body 2 is attracted to the magnet 32 of the support plate 3, and the tread base body 2 is held at the second position P2. By holding the tread base body 2 at the second position P2, as shown in FIG. 6, a work space can be secured between the pair of scaffolding plates SP. It is possible to move between levels through the building, and to pass building materials and the like between levels through this work space. Further, in the present embodiment, simply by lifting the tread body 2 to the second position P2, the tread body 2 is attracted to the magnet 32, and the tread body 2 is held at the second position P2. Is held at the second position P2, it is not necessary to perform a complicated operation such as locking the tread body 2 with a metal fitting or the like. Therefore, the tread base body 2 can be easily moved to the first position P1 and the second position P2, and the workability of the operator is improved. Further, when the worker moves on the scaffolding plate SP, vibration is transmitted from the scaffolding plate SP to the treadboard body 2. In the present embodiment, the treadboard body 2 is prevented from moving from the second position P2 due to the vibration. In addition, the magnet 32 holds the second position P2. Accordingly, it is possible to prevent the tread body 2 at the second position P2 from falling to the first position P1 due to vibration accompanying the movement of the operator, and injury of the operator due to the tread body 2 suddenly falling. Is prevented. Therefore, according to the bracket scaffolding tread 1 of this embodiment, the treadboard body 2 can be easily opened and closed, and the safety is enhanced.

  Next, when the tread body 2 is used again as a work floor, as shown in FIG. 5, the tread body 2 is pulled to the right in FIG. 5 by the handle 22 to resist the magnetic force of the magnet 32. Then, the footboard body 2 at the second position P2 is moved to the first position P1. As described above, the handle 22 is provided on the back surface of the tread body 2 so that the tread body 2 can be easily pulled.

  As described above, according to the present invention, it is possible to easily attach to the bracket scaffolding without being restricted by the position of the building site, and to secure a work space by storing the position that can be used as a work floor. Therefore, it is possible to provide a bracket scaffolding tread that can be switched to a position to be performed.
