Description

  The present invention relates to a morning glory device.

  The morning glory device is a device that is installed and used so as to project outward from the temporary scaffolding in order to prevent the fall of materials, tools, etc. from the temporary scaffolding at construction sites of medium- and high-rise buildings.

  As a conventional morning glory device, for example, in Patent Document 1, a temporary support is composed of a support arm composed of a main support material that supports both sides of the panel portion and a brace material connected to the lower surface of the main support material. A morning glory device is disclosed in which two frames are attached to each span of the building frame and one panel portion is supported by two support arms per span of the building frame.

Yes.

JP 2012-117340 A

  However, the morning glory device has room for improvement in the following points. That is, the building frames constituting the temporary scaffold are roughly classified into two types, that is, an inch size (1829 mm) building frame and a meter size (1800 mm) building frame. Therefore, the conventional morning glory device that supports one panel part with two support arms per span of the building frame needs to prepare both sizes separately in order to fit different sizes of building frames. It is difficult to easily cope with meter-sized building frames.

  On the other hand, in the conventional morning glory device that supports two panel parts with three support arms per two spans of the building frame, two panel parts on both sides are supported by one support arm by giving the support arm a width. Receive. Therefore, this morning glory device can cope with a certain size change of the building frame 1 span. However, this morning glory device needs to increase the cross-sectional area of the support arm to about 1.5 times in order to give the strength of the support arm that supports the two heavy panel portions. Therefore, this morning glory device has a problem that the mass of the device becomes large. An increase in the mass of the apparatus is not preferable because it makes it difficult to carry and install / disassemble work at the temporary site.

  The present invention has been made in view of the above background, and is obtained by providing a morning glory device that can easily cope with an inch-sized and meter-sized building frame and can be reduced in weight. It is a thing.

One aspect of the present invention is to connect a pair of main frame members disposed substantially in parallel with each other, a front end frame member that connects the front end portions of the pair of main frame members, and a base end portion of the pair of main frame members. A panel frame formed in a frame shape from the base end frame material, a plurality of plate members which are arranged in the frame of the panel frame to form a panel surface, and a distal end portion of the pair of main frame materials. A plurality of morning glory units having a pair of diagonally mounted diagonal members;
The base end of one main frame member and the base end of the other main frame member of the morning glory unit adjacent to each other are configured to be rotatable and slidable in the horizontal direction. An upper mounting bracket that is attached to a column of a building frame that constitutes a temporary scaffold,
The base part of the diagonal member of the morning glory unit and the base part of the other diagonal member of the morning glory unit adjacent to each other are configured to be rotatable and slidable in the horizontal direction. A lower mounting bracket that is attached to a column of a building frame;
A gap filling material that covers a gap formed between one main frame member and the other main frame member of the morning glory unit adjacent to each other;
One main frame member and the other main frame member of the morning glory unit that are provided across the gap filling material and are adjacent to each other are bound together, and the main frame member and the diagonal member slide in the horizontal direction. The morning glory device is characterized in that it has a bundling metal fitting that regulates the above.

  In the morning glory device, the base end of one main frame member and the base end of the other main frame member of the morning glory unit adjacent to each other can be rotated and slidably moved in the horizontal direction to the upper mounting bracket. Can be attached. Further, the base end portion of one diagonal member and the base end portion of the other diagonal member of the morning glory unit adjacent to each other can be attached to the lower mounting bracket so as to be rotatable and slidable in the horizontal direction.

  Therefore, the morning glory device changes its size by sliding the main frame and diagonal materials in the horizontal direction at the time of assembly, regardless of whether the horizontal span of the building frame is an inch size or a meter size. Can be attached to the upper mounting bracket and the lower mounting bracket. In addition, the morning glory device may bind one main frame material and the other main frame material of the morning glory units adjacent to each other with a binding metal fitting to restrict the horizontal movement of the main frame material and the diagonal material. it can. Therefore, the morning glory device can fix each morning glory unit so as not to slide and move in the horizontal direction. In addition, the gap formed between one main frame material and the other main frame material of the morning glory units adjacent to each other can be covered with a gap filling material, so that materials, tools, etc. can be dropped from the gap. Can be prevented.

  In addition, the conventional morning glory device has to increase the cross-sectional area of the support arm in order to support the panel portions on both sides having a large mass with a single support arm, and each frame member constituting the panel portion. The support arm was separate. Therefore, the conventional morning glory device tends to be large in mass. On the other hand, since the morning glory device only needs to receive the mass of a plate material or the like constituting the panel surface by the pair of main frame members and diagonal members, the cross-sectional areas of the main frame members and diagonal members can be reduced. Further, in the morning glory device, a pair of diagonal members is directly connected to a pair of main frame members constituting the panel frame. That is, the morning glory device can eliminate at least the main support material of the support arm in the conventional morning glory device. Accordingly, the morning glory device can be reduced in weight as compared with the conventional morning glory device. Therefore, the morning glory device can reduce the weight of each member such as the main frame material and the diagonal material, and can facilitate transportation, installation, and disassembly work at the temporary site.

  As described above, according to the present invention, it is possible to provide a morning glory device that can easily cope with building frames of inch size and meter size and can be reduced in weight.

  Next, an example of the assembly procedure of the morning glory device 1 will be described. First, the upper mounting bracket 31 is attached to a building frame column constituting the temporary scaffold, and the lower mounting bracket 32 is mounted and fixed to the building frame column at a position below the upper mounting bracket 31. Next, the main frame member 21 and the diagonal member 27 are connected in advance to form an assembly frame member, and various brackets such as the main frame member mounting bracket 214 and the diagonal member mounting bracket 275 are mounted at predetermined locations. . The assembled frame member can be transported to a temporary scaffold with the diagonal member 27 in a shortened state and the main frame member 21 and the diagonal member 27 folded.

  Next, one shaft portion 303 of the upper mounting bracket 31 is loosely inserted into the hole 214 a of the main frame member mounting bracket 214 in the assembly frame member, and the retaining plate 304 b is positioned in a direction perpendicular to the shaft portion 303. Accordingly, the base end portion of the main frame member 21 is attached to the upper mounting member 31 so as to be rotatable and slidable in the horizontal direction. Further, the diagonal member 27 in the assembly frame member is extended, and one shaft portion 303 of the lower mounting bracket 32 on the same side as one shaft portion 303 of the upper mounting bracket 31 is inserted into the hole 275a of the diagonal mounting bracket 275. While being loosely inserted, the retaining plate 304 b is positioned in a direction perpendicular to the shaft portion 303. Thus, the base end portion of the diagonal member 27 is attached to the lower mounting bracket 32 so as to be rotatable and slidable in the horizontal direction. Note that the assembly frame material is set up vertically so that the main frame material 21 follows the temporary scaffold.

  Next, the tip end portions of the pair of main frame members 21 in the pair of assembly frame members are connected by the tip end frame member 22, and the base end portions are connected by the base end frame member 23 to form the panel frame 20. In this example, the reinforcing material 26 is also attached to the panel frame 20 together.

Accordingly, the morning glory unit 2 rotates from the upper side to the lower side with the base end portion as a fulcrum, and the diagonal member 27 is shortened accordingly. Then, at a position where the morning glory unit 2 is in a posture of a predetermined angle (usually about 25 °) obliquely upward, the diagonal member 27 is fixed in a non-extensible manner by the fixing pin 272.

  When the plurality of morning glory units 2 are projected outside the straight portion in the temporary scaffold in this manner, a gap 4 is formed between one main frame member 21 and the other main frame member 21 of the morning glory unit 2 adjacent to each other. It is formed. In this example, the span of the column of the building frame is 1829 mm, and the horizontal width of the morning glory unit 2, that is, the interval L <b> 1 between the pair of main frame members 21 described above is 1794 mm. Therefore, a gap 4 of 35 mm is generated between the main frame members 21 of the morning glory units 2 adjacent to each other.

  Therefore, the gap filling material 5 is disposed so that the upper portion of the gap 4 is covered with the covering plate portion 51 of the gap filling material 5 while the legs 52 of the gap filling material 5 are fitted into the gap 4 between the main frame materials 21. Deploy. Thereafter, the binding metal fittings 6 are arranged so as to straddle the gap filling material 5 in a quarter of the main frame member 21 from the base end portion of the main frame member 21 toward the distal end side, and the morning glory units adjacent to each other The one main frame member 21 and the other main frame member 21 are bound together. In this example, specifically, the tip of the second extension 212 of one main frame 21 and the tip of the second extension 212 of the other main frame 21 of the morning glory unit 2 adjacent to each other, The state is made to contact the inner side surfaces of the pair of angle portions 61, and the two main frame members 21 are tightened in a direction approaching each other. As a result, the horizontal movement of the main frame member 21 and the diagonal member 27 is restricted.

  Next, a case where the morning glory device 1 of the present example is applied to a building frame (not shown) of a temporary scaffold having a distance between support centers of 1800 mm (meter size) will be described with reference to FIGS. 16 and 17.

  As shown in FIGS. 16 and 17, in this case as well, when a plurality of morning glory units 2 are projected outside the straight line portion of the temporary scaffold in the same manner as described above, one main frame of the morning glory units 2 adjacent to each other A gap 4 is formed between the material 21 and the other main frame material 21. However, in this case, the span of the column of the building frame is 1800 mm, and the horizontal width of the morning glory unit 2, that is, the interval L1 between the pair of main frame members 21 described above is 1794 mm. Therefore, the gap 4 formed between the main frame members 21 of the morning glory units 2 adjacent to each other is narrowed to 6 mm, as compared with FIGS. 15 and 11 described above. In addition, about another structure, it is the same as that of the case where the morning glory apparatus 1 of this example is applied to the building frame of the temporary scaffold whose distance between support | pillar centers is 1829 mm (inch size).

  Next, the effect of the morning glory apparatus 1 of this example is demonstrated. The morning glory device 1 is configured such that the base end portion of one main frame member 21 and the base end portion of the other main frame member 21 of the morning glory unit 2 adjacent to each other are rotatable and slidable in the horizontal direction. It can be attached to the mounting bracket 31. Further, the base end portion of one diagonal member 27 and the base end portion of the other diagonal member 27 of the morning glory unit 2 adjacent to each other are attached to the lower mounting bracket 32 so as to be rotatable and slidable in the horizontal direction. be able to.

  Therefore, the morning glory device 1 slides the main frame member 21 and the diagonal member 27 in the horizontal direction at the time of assembling regardless of whether the horizontal span of the building frame is an inch size or a meter size. It can be attached to the upper mounting bracket 31 and the lower mounting bracket 32 while corresponding to the size change. Further, the morning glory device 1 binds one main frame member 21 and the other main frame member 21 of the morning glory unit 2 adjacent to each other by the binding metal fitting 6 and slides the main frame member 21 and the diagonal member 27 in the horizontal direction. Movement can be regulated. Therefore, the morning glory device 1 can fix each morning glory unit 2 so as not to slide and move in the horizontal direction. Further, since the gap 4 formed between one main frame member 21 and the other main frame member 21 of the morning glory unit 2 adjacent to each other can be covered with the gap filling material 5, materials and tools can be used from the gap 4. Etc. can be prevented from falling.

  In addition, the morning glory device 1 only needs to receive the mass of the plate member 24 and the like constituting the panel surface by the pair of main frame members 21 and the diagonal members 27, so that the cross-sectional areas of the main frame member 21 and the diagonal members 27 can be reduced. it can. Further, in the morning glory device 1, a pair of diagonal members 27 is directly connected to a pair of main frame members 21 constituting the panel frame 20. Thus, the morning glory device 1 can be reduced in weight. Therefore, the morning glory device 1 can reduce the weight of each member such as the main frame member 21 and the diagonal member 27, and can facilitate transportation, installation, and disassembly work at the temporary site.

  Therefore, the morning glory device 1 can easily cope with a building frame of inch size or meter size, and as a result, the size of the morning glory device 1 can be unified. Moreover, the morning glory apparatus 1 can achieve weight reduction.

  Furthermore, the morning glory apparatus 1 can also have the following effects. That is, the morning glory device 1 has the main frame member 21 and the upper mounting bracket 31 and the lower mounting bracket 32 so as to be rotatable about the shaft portion 303 as a rotation axis and to be slidable in the horizontal direction along the shaft portion 303. Each base end portion of the diagonal member 27 can be easily attached. Therefore, the morning glory device 1 has an advantage that it is easier to obtain the above-described effects.

  Further, the morning glory device 1 can prevent the main frame member mounting bracket 214 or the diagonal member mounting bracket 275 from falling off from the tip end portion of each shaft portion 303 by the retaining mechanism 304. Therefore, the morning glory apparatus 1 can improve the mounting reliability of the morning glory unit 2 to the building frame.

  Further, the morning glory device 1 can fasten the main frame material 21 and the other main frame material 21 of the morning glory unit 2 adjacent to each other using the binding metal fitting 6 in the horizontal direction. The morning glory unit 2 can be easily fixed so as not to slide.

  Further, in the morning glory device 1, the main frame member 21 has a common shape (except for mounting holes for various metal fittings), so that the number of members to be manufactured can be reduced. Further, in the morning glory device 1, since the upper mounting bracket 31 and the lower mounting bracket 32 have the same shape, the number of members can also be reduced from this point.

  Moreover, since the morning glory apparatus 1 has the unit extension plate 231 and the gap filling extension plate 56 on the building frame side, the outside of a soundproof panel, a curing sheet, a curing net, an expanded metal frame and the like that can be arbitrarily attached to the temporary scaffolding It is also possible to deal with the difference in the width of the exit.

  As mentioned above, although the Example of this invention was described in detail, this invention is not limited to the said Example, A various change is possible within the range which does not impair the meaning of this invention.
