Description

  The present invention relates to a scaffold construction method for adjoining different types of scaffolds, and a scaffold constructed by such a construction method.

Conventionally, in construction sites, etc., strut pipes are connected vertically in a tenon-mortise relationship to form struts, and horizontal pipes (beam members) are installed at tight positions arranged at a predetermined interval on the strut pipes. In addition, a scaffolding plate is further installed between the horizontal pipes, and a reinforcing diagonal member and a handrail are arranged as necessary to assemble the temporary scaffolding. Such a support pipe as a support member for a scaffold is generally called a single pipe support and is often used when constructing a temporary scaffold for a relatively low-rise building. Patent document 1 is shown as an example of the temporary scaffold by such a single pipe | tube support | pillar.
On the other hand, a column member having a basic structure of a horizontal member as a connecting member for connecting a pair of left and right pedestal columns and both pedestal columns at the upper end position as a building frame is also used as a constituent member of a temporary scaffold. Building frames are generally used for high-rise buildings compared to using single-pipe struts because the assembly time is shorter than when using single-pipe props when building a temporary scaffold with the same structure. There are many cases. However, there is no strict difference between the two so that they must be used for the temporary scaffolding of the building. Patent document 2 is shown as an example of the temporary scaffold using a building frame.

Japanese Patent Laid-Open No. 11-22186 FIG. JP 2005-126936 A FIG.

As described above, since the single-pipe column and the building frame are completely different in shape, they are basically used separately as a column member for a scaffold, and are used as members for separately building a scaffold. Therefore, it is said that the height positions of the footboards set on them are to be coordinated between the scaffold using the single-pipe column as a column member (the former) and the scaffold using the building frame as the column member (the latter). There is no idea, and even in the present situation, the height positions of the treads set in the former and the latter are different. However, there is a possibility that the former and the latter are actually constructed adjacent to each other at the same site. In this case, it is inconvenient to go back and forth if the footboards of the two platforms are different. For this reason, there has been a demand for a technique that can easily make the heights of the treads the same, assuming that both scaffolds are adjacent. In addition, such a problem does not occur only in the scaffold constructed by the concrete column member such as the single pipe column and the building frame, but generally occurs when the height of the footboard is different between the two types of scaffolds. It is a problem that arises.
The present invention has been made paying attention to such problems existing in the prior art. The purpose is to construct a scaffold for making the height of the footboard the same when the height of the footboard differs between the two types of scaffolds, and a scaffold constructed by such a construction method. Is to provide.

  In order to achieve the above object, as means 1, a plurality of first strut members are connected in series in the vertical direction in the relationship of a tenon and a mortise to form a first strut, and the plurality of first struts are spaced at predetermined intervals. A first support column arranged upright and a fastening holder horizontally disposed between the first support columns adjacent to the first support column and formed at a predetermined fastening position of the first support member. A plurality of first beam members that are directly or indirectly connected to each other, and a plurality of second beam members that are installed on the binding holder that is horizontally disposed in a direction orthogonal to the first column of columns. A first scaffold in which a basic skeleton is formed by a beam member and a first or second row of first tread plates formed by placing a plurality of second treads on the second beam member And a plurality of second support members connected in series in the vertical direction to form a second support, A second support column in which two support columns are erected at a predetermined interval, a plurality of connecting members that connect the second support column in the column direction, and directly or indirectly on the second support member A scaffold constructed by adjoining two types of a second scaffold, in which a basic skeleton is formed by a first or multi-stage second footboard row formed by mounting a plurality of second footboards The first strut member has two or more tightening positions, the interval between the adjacent tightening positions is a first interval, and two pipe main bodies are connected to the tenon and the tenon. When the interval between the tightening position disposed closest to the tenon side and the tightening position disposed closest to the tenon hole when connected in series in relation to the tenon hole is the second interval, The length of the second interval is different from the first interval It was set to match the height of the first footplate column of the first scaffold to the height of the second footboard column of the second scaffold by settling.

With this configuration, the height of the first strut is adjusted by adjusting only the second interval without changing the first interval of the binding position of the first scaffold, and the second scaffold The height of the first footboard row on the first scaffolding side can be matched with the second footboard row on the side. In addition, the first interval of the tightening position is held firmly when the shaped member is mounted in the tightening position by adopting such a configuration, so that it is possible to mount the handrails, staircases and the like that are shaped. It is advantageous. Further, it is possible to cope with the case where the first interval is required to be a certain length or longer (or a certain fixed length) according to the standard.
Here, “adjusting the length of the second interval to be different from the first interval” means not to make the first interval and the second interval the same. On the other hand, even if the second interval is shortened or lengthened, it is sufficient if the heights of the first footboard row and the second footboard row coincide with each other. In addition, the term “match” means that when there are tread board rows in multiple stages, it means that the tread board rows at the corresponding positions match each other, and the match means a subtle height of at least several millimeters to several centimeters due to the nature of the scaffold. The difference is allowed as a matching range. Either “tenon” or “morte” may be on the upper side.

Further, as means 2, the number of the tightening positions of the first support member is three or more, and the first interval between the adjacent tightening positions is equal.
That is, when there are a plurality of regions having the length of the first interval, they are all preferably the length of the first interval. As a result, all but the second interval can be set to the same first interval, which is convenient when the shaped member is attached to the tightening position. In the case of three or four tightening positions, it is preferable that the second beam member is installed on the tightening holder at the lowermost tightening position position and the second tread plate row is placed. In the case where there are two tightening positions, it is preferable that the second beam member is installed on the tightening holder at the lower tightening position and the second tread plate row is placed. The second beam member may be supported in a cantilever shape or may be supported at two or more positions.

Further, as the means 3, the length of the lower region than the tightening position disposed at the lowermost position at the time of connection with respect to the reference support member having the same length as the first interval and the second interval. The length of the second interval was adjusted by using the first support column member that was changed only.
This is because when adjusting the length of the second interval, the length is adjusted only in the region below the lowest binding position of the first support member, and the other standards are the same as those of the reference support member. It is good to maintain, and it becomes advantageous when connecting the stylized member used for a reference | standard support | pillar member by such a structure, or using together with a reference | standard support | pillar member.

Further, as the means 4, when adjusting the length of the second interval, the mortise side end portion of the first strut member which is the lower side when connected and the most of the first strut member The length between the tense position arranged on the mortise side or the length between the tenon base of the first strut member which becomes the lower side when connected and the tight position arranged on the most tenon side I adjusted the height.
That is, like the means 3, when adjusting the length of the second interval, the length is adjusted in the region below the lowest binding position of the first support column member. As a result, the length above the lowermost binding position is always constant, which is convenient when a shaped member is attached to the fastening position.

Further, as the means 5, the second support column member is provided with a pair of front and rear legs and a horizontal part arranged between the legs.
If comprised in this way, since a 1st tread can be supported by a horizontal part, the construction operation | work of a 2nd scaffold is simplified.

Further, as means 6, a scaffold is constructed by any one of the construction methods 1 to 5, and the second scaffold of the second scaffold is set to the height of the first footboard row of the first scaffold of the scaffold. The height of the tread board rows was made to match.
In such a scaffold, the height of the first footboard row on the first scaffold side and the second footboard row on the second scaffold side are the same, so that from one scaffold to the other. When moving, there is no difference in height and it becomes easy to walk.
Further, as the means 7, a reference strut member having the same length between the first interval and the second interval is used for the first scaffold, and the tightening position of the reference strut member in the use state is the first scaffold. It was made to arrange | position at the same height position as the said binding position of 1 support | pillar member.
In this way, if the reference strut member has the same first spacing between the first strut member and the tightening positions, one tightening position with the reference strut member is made to coincide with the height of the tightening position of the second strut member. Accordingly, the heights of all the tightening positions coincide with each other, and it becomes possible to connect the shaped members between the reference support member and the second support member.

  According to the present invention, since only the second distance is changed, the height of the first footboard row of the first scaffold is set to the second height of the second scaffold while the first distance remains fixed. Can be matched to the height of the tread board row.

Hereinafter, as a specific embodiment of the present invention, a construction method of a temporary scaffold and a temporary scaffold constructed by such a construction method will be described with reference to the drawings.
In the present embodiment, a temporary scaffold 1 as shown in FIG. 1 is constructed as an example. The temporary scaffold 1 is composed of a first scaffold A that uses a single pipe strut 2 as a first strut member and a second scaffold B that uses a building frame 3 as a second strut member.
First, basic members for constructing the first scaffold A will be described.
As shown in FIG. 1, FIG. 2 and FIG. 5, the single pipe column 2 which is a member of the first scaffold A is a pipe member having a circular cross section made of an alloy, and in this embodiment, the length of the main body pipe 2a. Is set to 1725 mm. A tenon 5 is fitted and fixed to the inner peripheral surface of the upper end of one end of the main body pipe 2a. The tenon 5 is a pipe member having a circular cross section with its tip closed. A first pin hole 4 is formed at a position facing the base of the tenon 5 near the base by 180 degrees. From the first pin hole 4, the pin tip of the leaf spring type fixing pin 6 is exposed. The other end side of the main body pipe 2a is a mortise hole 7 into which the mortise 5 is inserted. A second pin hole 8 for a fixing pin is formed on the side surface closer to the mortise 7 at a position facing 180 degrees. In the present embodiment, the single tube support 2 is connected so that the tenon 5 side is the upper side and the tenon hole 7 is the lower side.

Tightening positions 10 are provided on the outer periphery of the main body pipe 2a at predetermined intervals along the longitudinal direction. In the present embodiment, the tightening positions 10 are provided at four locations, and the distances D1 (first distances) between the adjacent tightening positions 10 are equal (450 mm in the present embodiment). . The tightening position 10 is a pair of first tightening holders 11 arranged at the same height so as to face each other at 180 degrees, and is shifted by 90 degrees in the circumferential direction at a position shifted in the axial direction with respect to the first tightening holders 11. And a pair of second binding holders 12 arranged at the same height so as to face each other at 180 degrees. Both binding holders 11 and 12 are composed of a pair of left and right leg plates 13 and a connecting plate 14 for connecting the leg plates 13 on the outer end side of the both leg plates 13. The connecting plate 14 is slightly inclined with respect to the inclined main body pipe 2a so that the opening on the upper side when mounted is widened. At the four fastening positions 10, the phases of the attachment positions of the two fastening holders 11 and 12 are the same.
Because of such a configuration, the single tube support 2 is formed in a rotationally symmetric or mirror-symmetrical shape that coincides when rotated 180 degrees. For this reason, when the single tube struts 2 are connected, they can be connected even if the phase is changed by 180 degrees in the circumferential direction.

The single tube strut 2 configured as described above is obtained by adjusting the overall length with respect to the reference single tube strut 15 as a reference strut member as shown in FIG. That is, the standard single-tube support 15 of the conventional product is adjusted in order to cooperate with the second scaffold B using the building frame 3. The difference between the single tube strut 2 and the reference single tube strut 15 is that the single tube strut 2 is closest to the mortise 7 (that is, closer to the lower end when used) than the fastening position 10 (on the mortise 7 side). Is made shorter than the reference single pipe support 15. The center position of the binding position 10 is used as a reference, and in the reference single pipe support 15, the place where the distance from the mortise 7 is 240 mm is 165 mm shorter by 75 mm in the single pipe support 2. Therefore, when the total length of the reference single tube support 15 including the tenon 5 is 1925 mm, the total length of the single tube support 2 is 1850 mm. The other dimensions and the position of the fastening position 10 are all the same. In the present embodiment, shortening the single tube strut 2 by 75 mm with respect to the reference single tube strut 15 in this way facilitates coordination of the height positions of the first scaffold A and the footboard 25 of the second scaffold B. Adjustments.
As shown in FIGS. 2 (b) and 3 (b), comparing the case where two single tube struts 2 are connected with the case where two reference single tube struts 15 are connected, the reference single tube strut 15 Then, the interval between the tightening positions 10 of the connecting portions is also unified by the interval D1. On the other hand, in the single-tube strut 2 in the present invention, the interval D2 (second interval) of the coupling position 10 of the connecting portion is narrower than the interval D1. As will be described later, the distance D2 is 75 mm higher than the height of the footboard 25 of the second scaffold B when the height of the footboard 25 is equal to that of the first footing A using the reference single pipe support 15. Since it becomes higher, it is set according to the difference in height.

As shown in FIGS. 1 and 6A, the cloth material 18 as the first beam member is a pipe member having a circular cross section made of an alloy, and a wedge piece 19 is fixed to both ends. In this embodiment, the distance is 1800 mm. As shown in FIGS. 1 and 6B, the cloth material 21 as the second beam member is a pipe member having a circular cross section made of an alloy, and a wedge piece 19 is fixed to both ends. In this embodiment, it is configured with 200 mm. As shown in FIGS. 1 and 7, the overhanging bracket 20 as the second beam member includes a pipe member main body 20a having a circular cross section, a wedge piece 19 at the base of the main body 20a, and an auxiliary member erected on the tip of the main body 20a. It is comprised from the support | pillar part 22 and the diagonal material 23 formed in the main body 20a lower part. Holders 24 are formed on both side surfaces of the auxiliary support column 22 on the lower side (only one of them is shown in FIG. 7). As shown in FIG. 8, the footboard 25 of the present embodiment is a member having a rectangular appearance in which a frame (not shown) is fixed to the back surface of a plate portion 25a made of a steel plate, and an engagement hook 26 is provided at an end portion in the longitudinal direction. Is formed.
The first scaffold A can be three-dimensionally constructed by the single pipe support 2, the cloth materials 18 and 21, the overhang bracket 20, and the footboard 25 as described above. In the present embodiment, as shown in FIG. 1, a leading handrail 27, first to third auxiliary columns 28a to 28c, and a pipe support 30 are used as auxiliary members. The upper part of the pipe support 30 is inserted into the mortise 7 of the single pipe support 2 to support the single pipe support 2 at a predetermined height. The first auxiliary strut 28a is a specification when there is one tightening position 10 of the reference single pipe strut 15, and the second auxiliary strut 28b is a specification when there are two tightening positions 10 of the reference single pipe strut 15. The third auxiliary column 28c is a specification in the case where there are three binding positions 10 of the reference single tube column 15, and is a conventional column member.

Next, basic members for constructing the second scaffold B will be described.
As shown in FIG. 4, the building frame 3 has a basic skeleton composed of a pair of left and right pedestal pipes 31 and a connection pipe 32 that connects both pedestal pipes 31 at the upper end position. A reinforcing frame 33 is disposed on the inner surface of each pedestal pipe 31. A cloth material attaching portion 34 is formed at an inner position near the upper and lower ends of the both pillar pipes 31. As shown in FIG. 9, the bracing 35 as a connecting member includes two main body pipes 36 and a connecting plate 41 in which connecting holes 37 formed at both ends of both the main body pipes 36 are formed. The brace 35 is connected so as to be rotatable at the center in the longitudinal direction of the two main body pipes 36. As shown in FIG. 10, the lower rail 38 as a connecting member includes a main body pipe 39 and a connecting plate 44 in which connecting holes 40 formed at both ends of both the main body pipes 39 are formed. The step board 25 is the same as that of the first scaffold A (the width and the number of sheets in the width direction are different).
The second scaffold B can be three-dimensionally constructed by the building frame 3, the bracing 35, the lower rail 38, and the footboard 25 as described above. In this embodiment, as shown in FIG. 1, a leading handrail 42 and a clamp-type end stopper 43 are used as auxiliary members. The pipe support 30 is the same as that of the first scaffold A.

Next, the temporary scaffold 1 is demonstrated based on FIG.1 and FIG.11.
In the present embodiment, first, the second scaffold B is constructed and the height of the footboard 25 is determined. First, in order to construct the second scaffold B, the pillar pipes 31 of the building frame 3 are connected (connected) in a vertical and vertical relationship with a plurality of pipe supports 30 and arranged at predetermined intervals. The pipe support 30 is finely adjusted so that the connecting pipe 32 of the building frame 3 is horizontally arranged. Then, the bracing 35 and the lower crosspiece 38 are attached to the cloth material attaching portion 34 of the building frame 3, and the tread board 25 is installed on the connecting pipe 32 of the adjacent building frame 3 so as to form a row of the tread boards 25. Go. When the first stage is completed in this way, the second stage building frame 3 is connected to the first stage building frame 3, and the second stage is constructed in the same manner as described above. Next, the handrail 42 and the end stopper 43 are attached (the end stopper 43 may be provided later). In the present embodiment, up to the second level is displayed in FIG. The height of the footboard 25 of the second scaffold B constructed in this way is always equal since the second to upper steps only add the building frame 3 (because the ground is not necessarily horizontal in the first step). It depends on how the pipe support 30 is adjusted). Note that this second scaffold B construction method is an example, and may be constructed by other procedures.

Next, the first scaffold A is constructed. In the first scaffold A of the present embodiment, the inclined platform 50 is installed on the assumption that a slope is installed as the installation location, and is constructed thereon.
The first to third auxiliary columns 28a to 28c corresponding to the height of the inclined base 50 are connected (connected) to the plurality of pipe supports 30 and arranged at predetermined intervals. Since the upper ends (tips of the tenon 5) of the first to third auxiliary struts 28a to 28c need to be arranged horizontally, they are adjusted by the pipe support 30. At the same time, the cloth material 18 is connected horizontally to the corresponding fastening positions 10 between the adjacent first to third auxiliary columns 28a to 28c. Subsequently, the single tube strut 2 is connected to each of the auxiliary struts 28a to 28c, and two cloth materials 18 are connected in parallel to the two fastening positions 10 counted from above, and counted from above. Two cloth materials 21 are attached to each of the third binding positions 10. The cloth material 21 extends in a direction orthogonal to the cloth material 18. Then, the footboards 25 are constructed so as to form a row of the footboards 25 on the cloth materials 21 between the adjacent single pipe columns 2. At this stage, the pipe support 30 on the first scaffold A side is finely adjusted in order to match the height of the second scaffold B constructed previously with the step board 25 of the second scaffold B. By this adjustment, the height of the first step board 25 of the first scaffold A can be arranged at the same height as the height of the first step board 25 of the second scaffold B.
Next, the single-tube strut 2 that is the second stage is connected to the first-stage single-tube strut 2. Similarly, the two cloth members 18 are connected, the overhang bracket 20 is attached to the third binding position 10 counted from above, and the tread plate 25 is installed on the overhang bracket 20. In the present embodiment, the tread plate 25 is constructed on the overhanging bracket 20 from the second step to the upper step. The height of the footboard 25 of the first scaffold A constructed in this way is always equal pitch because the upper stage from the second stage only adds the single pipe support 2. Since the height of the first step board 25 of the first scaffold A is the same as the height of the first step board 25 of the second scaffold B, the height of the step board 25 of both the scaffolds A and B is always high. Will match. In the present embodiment, up to the second level is displayed in FIG. This first scaffold A construction method is an example, and may be constructed by other procedures.

  Moreover, in the 1st scaffold A of this Embodiment, the 2nd auxiliary | assistant support | pillar 28b is connected with the auxiliary | assistant support | pillar part 22 of the overhanging bracket 20 of the single-tube support | pillar 2 of the 2nd step | paragraph. The single tube strut 2 is configured in the same shape as the conventional reference single tube strut 15 in the region above the tightening position 10 closest to the mortise 7 (that is, the lower end is closer when used) as described above. Yes. That is, the distance between the tightening positions 10 and the length from the tightening position 10 to the tip of the tenon 5 are the same as those of the conventional reference single tube strut 15, second and third auxiliary struts 28b, 28c. Yes. Therefore, the height position of the tightening position 10 of the second auxiliary column 28b coincides with the height position of the tightening position 10 of the single tube column 2.

  Here, for comparison, a case is assumed in which the first scaffold A is constructed using the conventional reference single pipe support 15. As shown in FIG. 12, even in this case, the height of the first step board 25 can be matched with the height of the step board 25 of the second scaffold B by adjusting the pipe support 30. However, in the second and subsequent stages, the pitch of the reference single tube support 15 is different from that of the second scaffold B, and therefore becomes higher than the footboard 25 of the second scaffold B. In FIG. 12, it is 75 mm higher than the height of the footboard 25 of the second scaffold B at the second stage. This difference is accumulated as the number of steps of the scaffold increases. Therefore, if the reference single-pipe column 15 is used instead of the single-tube column 2 of the temporary scaffold 1, the difference in the height of the temporary scaffold 1 with a large number of steps is obtained. The difference in height between the footboards 25 of both the scaffolds A and B becomes very large, and movement between the first scaffold A and the second scaffold B becomes very difficult. On the other hand, as described above, in the temporary scaffold 1 of the present embodiment, the heights of the footboards 25 of both the scaffolds A and B always coincide.

By configuring as described above, the temporary scaffold 1 of the present embodiment has the following effects.
(1) Since the first scaffold A and the second scaffold B have the same height of the footboard 25 at all levels, the movement between the first scaffold A and the second scaffold B can be facilitated.
(2) If the height of the first step board 25 in the first scaffold A is set to the same height as the height of the first step board 25 of the second scaffold B, all the upper steps are automatically higher than that. Since the steps 25 have the same height, the adjustment for each level is unnecessary.
(3) Since the interval D1 between the fastening positions 10 of the single pipe struts 2 is the same as that of the reference single pipe strut 15 as a conventional product, the conventional parts (in the above, the first position) Even when the two auxiliary struts 28b) are attached, the positional relationship of the conventional parts can be maintained in the same manner as the reference single tube strut 15. That is, it becomes possible to mount the conventional parts on the single tube support 2.
(4) Since the length above the lowermost fastening position 10 of the single pipe support 2 is always constant, only the length below the lowermost fastening position 10 is adjusted. For example, if the length below the lowermost binding position 10 is changed for the scaffolds with different standards other than the second scaffold B, the height of the step board 25 is also increased for the scaffolds with different standards other than the second scaffold B. Can be coordinated.

It should be noted that the present invention can be modified and embodied as follows.
In the above embodiment, the distance D2 is shortened with respect to the distance D1, but the distance D2 may be longer than the distance D1 depending on the height of the second scaffold B.
In the above embodiment, the first scaffold A and the second scaffold B are adjacently supported separately from each other, but may be connected by a connecting means such as a clamp device.
In the first scaffold A, the tightening position 10 is used as the single pipe support 2 in four patterns. However, if the standard changes, for example, the tightening position 10 may be realized in three or more patterns.
A member used for the reference single tube strut 15 other than the first to third auxiliary struts 28a to 28c may be applied to the first scaffold A.
In the first scaffold A, the tread plate 25 is supported by the overhanging bracket 20 extending in a cantilever shape, but may be supported by beam members supported on both sides.
As an example of the second scaffold B, the temporary scaffold 1 other than the scaffold using the building frame 3 may be used.
The vertical relationship between the tenon 5 and the tenon hole 7 of the single-tube support 2 may be reversed. In the case of reverse rotation, the distance between the base portion of the lower tenon 5 and the lowermost fastening position 10 may be adjusted with respect to the corresponding reference single tube support column.
In the above embodiment, the cloth material 18 is directly connected between the fastening positions 10 (that is, the fastening holders 11, 12) of the single tube support 2, but other connecting members are installed on the fastening holders 11, 12. However, the cloth member 18 may be indirectly connected to the single pipe support 2 with respect to the connecting member.
-Besides, it is free to implement in a mode that does not depart from the gist of the present invention.
