Description

  The present invention relates to a temporary scaffold used indoors and outdoors in construction sites such as a construction site and a civil engineering site, in particular, a binder used in a wedge-tight scaffold or a system support, and a temporary scaffold incorporating this binder. About.

  Temporary scaffolds at construction sites include frame scaffolds used mainly during construction of buildings, single pipe scaffolds used mainly during construction of houses and wedge-tight scaffolds, and system support (form support) A rolling tower is also an example of a temporary scaffold.

For example, a temporary scaffolding is a type that uses a pillar member with a connecting piece such as a frame on the side and a short joint material (a short joint material is sometimes referred to as an arm wood) (a wedge-tight scaffolding) ) And vertical columns (also referred to as building materials) and horizontal pedestals (also referred to as horizontal materials) that use building frames such as H shapes and torii shapes (framework scaffolds), both facing each other A cloth frame with a floor (also referred to as a cloth board) is bridged between short connecting materials or horizontal rails, and used as a work floor or a passage for workers. In addition, the system support works are arranged in a matrix of columns that are formed by connecting column members, such as frames, that are provided on the side surfaces in a vertical direction, and two types of long and short connecting materials between the connection members of these column members. It is a tightly bound structure formed by connecting in two horizontal directions, and can be used as a work floor or a worker's passage by appropriately laying a cloth frame with a floor between connecting materials facing each other. In addition, pipes made of steel or aluminum are often used for support members, connecting materials, building frames, and the like.

  Thus, in the wedge-tight scaffolding and system support work, the support member and the connecting material are used. In addition, as a connection metal fitting provided in the side surface of a support | pillar member, the top etc. which are provided in multiple numbers on the side of a support | pillar member, the flange provided cyclically | annularly in the side of a support | pillar member, etc. can be used. And the wedge metal fitting provided in the edge part of a connecting member can be attached to connection metal fittings, such as a top and a flange, and can be fastened with a wedge.

  The wedge-tight scaffolding is constructed by attaching a short connecting material (also called arm timber), brace material, and a scaffolding member such as a handrail member to a support member provided on the side with a connecting bracket such as a frame, and Then, after these scaffold constituent members are fastened together with wedges in the connecting metal fitting, they are assembled by bridging one or more cloth frames with floors. In addition, after forming a scaffold by crossing a cloth frame with a floor, a handrail is provided at least at the opposite side of the building to prevent the worker from falling.

  FIG. 1 shows an example of the structure of a wedge-tight scaffold. (a) is a front view of a wedge-binding scaffold, (b) is an enlarged view of the periphery of the top indicated by a circle in (a), and (c) is a right side view of the wedge-binding scaffold.

  Here, three support columns 1 of the wedge-binding scaffold are erected on the building 14 side and on the opposite side. Each strut 1 is formed by adding a strut member 3 having a plurality of tops 4 in the vertical direction via a tenon material (not shown). A short tether 2 is attached via a frame 4 between the building-side column 1 and the column 1 on the opposite side of the building, and the frame 4 is fastened with a wedge (not shown). A brace member 21 is attached between the adjacent struts 1 on the building side via the top 4, and a handrail member 20 is interposed between the adjacent struts 1 on the side opposite to the building via the top 4. They are attached and fastened with wedges in the top 4 respectively. Then, one or two or more floor-attached cloth frames 9 are bridged between the adjacent short connecting materials 2 to form a first-stage scaffold. The brace material 21 may be attached between the columns 1 on the opposite side of the building.

  The second stage scaffold is formed in the same manner as the first stage scaffold. If necessary, a strut member 3 separately prepared on the upper end of the strut member 3 of the first stage scaffold is added in the vertical direction via a tenon material (not shown), and then the short tether 2 and brace The material 21 and the scaffold component member of the handrail member 20 are attached via the frame 4, and these scaffold component members are fastened together by wedges (not shown) at the frame 4, and then between the adjacent short-length connecting materials 2. It is formed by spanning one or more floor-mounted cloth frames 9. By repeating this in sequence, a multi-stage wedge-binding scaffold is assembled.

  On the other hand, system support is a scaffold often used when constructing concrete structures, etc., and is a system support that can be assembled from the ground or floor surface by combining multiple single members such as jack base, support material, and horizontal material. It is used as a work floor, a worker's passage, etc. by appropriately laying a cloth frame with a floor on the work.

  In other words, support columns, each of which has a connecting member such as a plurality of frames, provided on the side surface are connected in a matrix with columns connected to each other, and the connecting members such as the frames of these supporting members are arranged in a matrix. Two types of long and short connecting materials (which may be the same length) are attached at right angles to each other in two horizontal directions via a connecting fitting such as a frame, and are attached to the column member by wedges in the connecting fitting such as a frame. Work in a tightly bound structure (system support work) formed by tightly binding to two horizontal directions at right angles to one or two or more floor-attached cloth frames between facing ties. It is used as a floor or a passage for workers. In addition, the handrail for preventing a worker's fall can also be provided in the place where the cloth frame with a floor was bridged.

  FIG. 2 is a front view showing an example of the system support work, and FIG. 3 is a right side view of the system support work of FIG. 4 is a cross-sectional plan view taken along line AA in FIG.

  In this example, the system support work 100 is installed at a height of several m to several tens m from the ground so as to support the lower surface of the formwork 102 above the concrete structure (slab) 101.

  The system support 100 is formed by arranging a plurality of support columns 1 in a matrix at predetermined intervals, and connecting the adjacent support columns 1 with a plurality of connecting members 2 in the horizontal direction. Each strut 1 is composed of a plurality of strut members 3 connected in the vertical direction via a tenon material (not shown). The lower end of each column 1 is supported by a jack base 5. A large jack jack 6 is attached to the upper end of each strut 1, and a plurality of large pull materials 7 are placed on the large jack jack 6. Further, a plurality of joists 8 are placed on the plurality of large joists 7 and the formwork 102 is placed on the plurality of joists 8 so as to be orthogonal to the large joists 7.

  Four frames 4 are formed in a cross shape at predetermined intervals on the side surface of the column 1 (see FIG. 4). The connecting material 2 is connected to the frame 4 via a wedge metal piece joined to both ends of the connecting material 2 and is fastened by a wedge 2a. Here, the connecting material 2 is not attached to the central piece 4 of each support member 3, but the connecting material 2 may be attached to the central piece 4 of each support member 3.

And as shown in FIG. 4, the cloth frame 9 with a floor is bridged between the connecting materials 2 which face. In the same manner, a scaffold for use as a work floor or a worker's passage can be formed where necessary by laying the cloth frame 9 with a floor on other places. Here, two scaffolds with floors are arranged side by side between the connecting members 2 facing each other to form one scaffold, which is used as a work floor or a passage.

  As described above, in the wedge-tight scaffold and the system support work, the support members having the connection brackets such as frames are provided on the side surfaces, and the support members can be connected in the horizontal direction by the connecting material.

  The connecting material used here is made of steel or aluminum pipes with a wedge fitting joined to both ends of the pipe by welding or the like. By being fastened together, it can be used fixed to the column member.

  FIG. 5 is a front view of an example (conventional example) of a connecting material used in a wedge-tight scaffold or system support work.

  This connecting material 2 is formed by joining a wedge metal fitting 2b to both ends of a horizontal member 31 made of a pipe made of steel, aluminum or the like by welding or the like, and its total length is adjusted to the interval between the support members 3. . The hook member 2b of the connecting member 2 is hooked on a connecting metal member such as the top 4 provided on the side surface of the column member 3 and then fastened by the wedge 2a, whereby the column members 3 can be connected and fixed.

  Regarding this binder, in order to increase the strength of the binder itself, or to firmly connect the binder to the support member, a cane is provided obliquely from the lower part of the binder to the support. Has been proposed (see Patent Document 1 and Patent Document 2).

  FIG. 6 is a front view of an example (conventional example) of a connecting material with a cane disclosed in Patent Document 1. FIG.

In addition to joining the wedge metal fittings 2b to both ends of a horizontal member 31 made of a pipe made of steel, aluminum or the like by welding or the like, the connecting member 30 with a cane is a horizontal member for increasing the strength of the connecting member itself. Two wands 32 that support 31 from diagonally below are provided. The lower end portion of each cane 32 has a semi-cylindrical vertical plate 33 having an inner diameter substantially the same as the outer diameter of the column member 3, and the vertical plate 33 is pressed against the side surface of the column member 3. It has been. Further, in order to prevent deformation of the connecting member 30 with the cane, one bundle member 34 is installed vertically from the vicinity of the left and right ends of the horizontal member 31, and connects with the respective canes 32. Thus, each wand 32 is supported from above. The wedge bracket 2b joined to both ends of the horizontal member 31 of the tether, after hooking the connecting fitting frame 4 or the like provided on the side surface of the strut member 4, respectively, by Tightened by wedge 2a, strut member 4 It is possible to connect and fix between.

  FIG. 7 is a front view of an example (conventional example) of a connecting material with a cane disclosed in Patent Document 2. FIG.

In addition to joining the wedge metal fittings 2b to both ends of a horizontal member 31 made of steel, aluminum, or the like, the tie member 30 with the cane is joined to the two members that support the horizontal member 31 obliquely from below. A cane 32 is provided. Moreover, the wedge metal fitting 30b is joined also to the lower end part of each cane 32 by welding etc. FIG. Further, in order to prevent deformation of the connecting member 30 with the cane, one bundle member 34 is vertically installed from the vicinity of the left and right end portions of the horizontal member 31 and is connected to each of the canes 32. Thus, each wand 32 is supported from above. After the wedge metal fitting 2b joined to both ends of the horizontal member 31 of this connecting material is hooked on a connecting metal fitting such as the top 4 provided on the side surface of the column member 3, the wedge metal 2b is fastened by the wedge 2a. After hooking the wedge metal fitting 30b provided at the lower end portion of the frame member 4 to the connecting metal fitting such as the top 4 provided on the side surface of the column member 3, the wedge member 30a is tightened to firmly connect the binder material to the column member 3. Can be connected and fixed.

  Thus, the strength of the connecting material itself can be increased by providing the staff with the connecting material in which the wedge metal fittings are joined to both ends of the horizontal member made of a pipe made of steel or aluminum. In particular, since the tie material with a wand formed by joining a wedge metal fitting to the lower end of the wand has a great binding effect due to the wedge, the tie material can be firmly connected and fixed to the support column.

  However, when assembling these tie members with a cane, it is necessary to tie the two or four wedge metal fittings provided on the left and right ends to the connecting metal fitting on the side surface of the column member with the wedges. However, since the wedge part joined to both ends of the horizontal member exists at a high place, there is a problem that it is difficult for a worker to reach the hand, so that it is difficult to tighten the wedge. In addition, in the tie material with a wand formed by joining the wedge metal fittings to the lower ends of the left and right wands, there are four wedge metal fittings.

  FIGS. 8 and 9 are examples of binding work by wedges when attaching the tie member with the wand shown in FIG. 7 between the strut members.

  In this tie member 30 with a cane, since the wedge metal fitting 2b joined to both ends of the horizontal member 31 is present at a high place, it is difficult for an operator to reach the hand during tightening work with the wedge 2a. Not only is the tightening operation to be driven difficult, but also there are four wedge metal fittings 2b and 30b, so that it can be seen that there is a problem that the tightening operation of driving the wedges 2a and 30a with the hammer 36 is troublesome.

  The present invention has been made to solve the above-described problems, and can facilitate and reduce the connection work with the support member, and can be firmly connected to the support member. It is an object of the present invention to provide a tie material that can be used, and a temporary scaffold incorporating the tie material.

  The present inventors have made various studies in order to solve the above problems. As a result, the following findings (a) to (e) were obtained.

  (a) As a tie material that can be firmly connected to the support material, the basic material consists of a horizontal member made of steel or aluminum pipes and two wands that support the horizontal member obliquely from below. It is preferable to adopt a general configuration and to have a structure that can be firmly connected to the left and right support members at a total of four positions, ie, both ends of the horizontal member and the lower ends of the two canes. Therefore, in order to firmly connect to the column member, as shown in FIG. 6, a structure in which only a semi-cylindrical vertical plate is provided and this vertical plate is pressed against the side surface of the column is used. Instead, as shown in FIG. 7, it is preferable to provide a wedge metal fitting at the lower ends of the two canes so that all four places can be fastened with wedges. However, as shown in FIG. 7, the tie member with the wand shown in FIG. 7 has a wedge metal fitting joined to both ends of the horizontal member at a high place. This is not only difficult to tighten, but also has a total of four wedge metal fittings, and there is a problem that it takes time and labor for the wedge.

  (b) The inventors of the present invention have studied a method that can firmly connect the tie member with the cane to the support member even if the four parts are not fastened with wedges. As a result, instead of fastening all four points on the left and right ends of the horizontal member of the bridging member with the cane and the lower ends of the two left and right canes with two wedges, two places on the both ends of the horizontal member. In this case, instead of binding with a wedge, it has been thought that the tie member with the cane can be firmly connected to the left and right support members by hooking to the support members.

  That is, out of the four connecting means of the connecting material with the cane, the two left and right portions of the both ends of the horizontal member present at the high place are connected by hooking to the column member instead of being fastened with the wedge, The two lower ends of the left and right canes are fastened together using wedges. Here, examples of the latching method between the end of the horizontal member and the support member include a combination of a button pin and a notch having a shape that can be latched on the button pin. Since the button pin is composed of a button part (large diameter) and a mounting shaft (small diameter), if the width of the notch is smaller than the outer diameter of the button part and larger than the outer diameter of the mounting shaft, the end of the horizontal member The part can be hooked on the column member, and the end of the horizontal member is difficult to come off from the column member after hooking. In addition, although a button pin will be provided in either the side surface of a support | pillar member, or the edge part of a horizontal member, welding, a screw, etc. are employable as the joining means.

  With such a latching structure, the wedge metal fitting for binding the wedge can be halved to only the two lower end portions of the left and right canes, and the height at the two left and right ends of the horizontal member can be reduced. This eliminates the need for a wedge work at the place. Therefore, it is possible to facilitate and reduce the binding work by the wedge.

  (c) When a combination of a button pin and a notch having a shape that can be hooked to the button pin is used as a hooking means between the end of the horizontal member and the column member, the button pin and the button pin are hooked. Specifically, the combination of notches having a shape that can be formed is the following (i) or (ii).

  (i) A button pin is provided on the side surface of the support member, and on the other hand, an end plate having a downward cutout is provided at the end of the horizontal member, and the end of the horizontal member is moved downward from above. Fit the downward notch on the button pin. In the case of a button pin comprising a button part and its mounting shaft, the width of the downward notch provided on this end plate is larger than the outer diameter of the mounting shaft and smaller than the outer diameter of the button part. To do. Here, since it is necessary to move the button portion simultaneously with the mounting shaft, an opening enough to accommodate the button portion is provided below the end plate or below the end portion of the horizontal member. As described above, the button pin can be joined to the side surface of the support member by welding or a screw. Considering the labor of joining, it is preferable to join with screws such as blind nuts. In addition, the horizontal member that is hooked on the side surface of the support member is not limited to one direction, but may be 2 to 4 directions on the periphery of the support member. The number of button pins to be installed is 1 to 4. When a plurality of button pins are joined to the circumference of the side surface of the support member by screws, it is preferable to use a blind nut.

  (ii) An upward notch is provided on the side of the support member, while a button pin is provided at the end of the horizontal member, and the button pin is moved upward by moving the end of the horizontal member downward from above. Fit into the notch. Here, the width of the upward notch provided on the side surface of the support member is larger than the outer diameter of the button pin mounting shaft and smaller than the outer diameter of the button portion. The upward notch may be formed by attaching a thin frame on the side surface of the column and providing an upward notch on the front wall of the thin frame. Here, the thin frame may have a shape with a missing bottom surface. As described above, the button pin can be joined to the end of the horizontal member by welding or a screw. Considering the labor of joining, it is preferable to join with screws such as blind nuts.

  As a result, as shown in (i) above, the end of the horizontal member is moved downward from above, and the button pin provided on the side surface of the column member is moved downward to the end plate provided on the end of the horizontal member. By engaging the notch portion, when the end portion of the horizontal member and the support member are connected, the connection is not released unless the end portion of the horizontal member is moved upward. In other words, since the horizontal member is a part of the connecting material with the cane, the connection is not released unless the connecting material with the cane is moved upward. Note that the end of the horizontal member is rotatable about the button pin provided on the side surface of the support member, so that it is not always necessary to move the end of the horizontal member from above, but from the side or from below. Even if it is made to do, the edge part of a horizontal member can be hooked on a button pin.

Further, as described in (ii) above, the end of the horizontal member is moved downward from above, and the button pin provided on the end of the horizontal member is hooked on the upward notch provided on the side surface of the column member. By stopping, even when the end of the horizontal member and the support member are connected, the connection is not released unless the end of the horizontal member is moved upward. In other words, since the horizontal member is a part of the connecting material with the cane, the connection is not released unless the connecting material with the cane is moved upward. Since the end of the horizontal member is rotatable about the upward notch provided on the side surface of the column member as a rotation axis, it is not always necessary to move the end of the horizontal member from above. Even if it is moved from below, the end of the horizontal member can be hooked to the upward notch .

  Furthermore, the wedge metal fittings provided at the lower ends of the left and right wands of the tie material with the wand have a shape that can be held by sandwiching the connecting members such as the top and the flange of the support member from above and below, for example, a C-shape when viewed from the front It is preferable to have. When the wedge metal fitting has such a shape, once the connecting material with the cane is connected to the support member, even if the connecting material with the cane tries to move up and down, it will hit the connecting member of the support member, It can prevent that a binder with a cane comes off from a support | pillar member.

  (d) As a modification of the above (ii), instead of providing a button pin at the end of the horizontal member as a latching means, a circular end plate having an outer diameter larger than the outer diameter of the horizontal member may be provided. Good. That is, an upward notch portion having a width smaller than the outer diameter of the circular end plate is provided on the side surface of the column member, and the circular end plate provided at the end portion of the horizontal member is moved downward from above. This button pin is fitted into the upward cutout.

In this way, the end plate of the horizontal member is moved downward from above, and the circular end plate provided on the end of the horizontal member is hooked on the upward notch provided on the side surface of the column member. Accordingly, even when the circular end plate provided at the end of the horizontal member is connected to the support member, the connection is not released unless the end of the horizontal member is moved upward. In other words, since the horizontal member is a part of the connecting material with the cane, the connection is not released unless the connecting material with the cane is moved upward. Since the end of the horizontal member is rotatable about the upward notch provided on the side surface of the column member as a rotation axis, it is not always necessary to move the end of the horizontal member from above. Even if it is moved from below, the end of the horizontal member can be hooked to the upward notch .

  (e) As described above, the end portion of the horizontal member is rotatable about the button pin provided on the side surface of the column member or the upward cutout portion as the rotation axis. That is, the tie material with the cane is rotatable about the button pin provided on the side surface of the support member or the upward notch as the rotation axis. Therefore, after the end of the horizontal member and the support member are connected, the wedge fitting provided at the lower end of the cane is fastened to the connection member of the support member with the wedge, and the wedge fitting and the support member at the lower end of the support member are connected. It is possible to easily align the connecting metal fittings.

  The present invention has been completed on the basis of the above findings, and the gist thereof is the following (1) to (9) tie material with a cane and the following (10) temporary scaffold. Hereinafter, the present invention is collectively referred to as the present invention.
