TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for constructing an assembling building material without scaffolding, and more particularly to a method for constructing an assembling building material without scaffolding by transporting a grounded assembling building material to a construction height and attaching it to a structure of a building.
[0002]
[Prior art]
Japanese Patent Publication No. 5-52389 (Prior art 1) discloses a method of scaffolding an outer wall steel plate. According to this, on a stage with legs, a plurality of outer wall steel plates are connected and integrated by a frame material and a panel vertical frame to assemble a large panel. They are transported to the construction site for steel frames.
[0003]
Japanese Patent Application Laid-Open No. Hei 8-239928 (Prior art 2) describes that a grounded outer wall unit is lifted to a construction height by a crane and transported. Further, it is described that the outer wall unit secures the accuracy of the body edge during transportation and prevents deformation by attaching bolts to the vertical and horizontal body edges as base steel frames.
[0004]
In the preceding example 1 or 2, the procedure of assembling the assembled building material such as a large panel or an outer wall unit and lifting it to a construction height is adopted, so that the parts of the assembling building material are transported from the factory to the ground level. Just do it. Therefore, there is an advantage that the transportation cost is reduced as compared with a case where the assembled building material assembled in the factory is transported to a construction height and lifted.
[0005]
[Problems to be solved by the invention]
However, in the non-scaffolding method described in the first and second examples, the assembled building material itself such as a large panel or an outer wall unit needs to have strength enough to withstand lifting by a crane. As described in 2, it is required that the assembled building material be unnecessarily reinforced with a reinforcing steel material and a tension material in order to have a strength enough to withstand the lifting of the assembled building material. There is a problem that the construction cost is increased due to the extra cost, material cost, manufacturing cost and weight increase of the assembled building material.
[0006]
Also, in the construction methods of Prior Examples 1 and 2, because the assembled building materials are directly lifted by a crane, the assembled building materials shake during the lifting and interfere with the ground or the structure of the building. Therefore, there is a problem that the assembled building material is easily damaged during lifting.
[0007]
Further, the stages and the like used in the construction methods of the first and second prior examples only serve as mere work benches for assembling the assembling building materials. It is not something to show. Therefore, it takes a long time to assemble the building materials on a stage or the like.
[0008]
The present invention has been made in view of the above problems and situations. In other words, the present invention eliminates the need to give the assembled building material strength to withstand lifting when transporting the erected assembled building material to a construction height, and uses an extra reinforcing material such as a reinforcing cord material or a tension material. It is an object of the present invention to provide a method for constructing an assembling building material without scaffolding, which can eliminate the necessity of construction.
[0009]
In addition, the present invention makes it difficult for the assembled building material to swing and interfere with the ground or the structure of the building during lifting when the assembled building material is transported to a construction height by using a crane. It is an object of the present invention to provide a method for constructing an assembling building material without scaffolding, which can reduce damage in the inside.
[0010]
Further, according to the present invention, the jig itself used for laying the assembled building material has a function of improving the assembling accuracy of the assembled building material, so that the laying work on the jig can be accurately performed in a short time. An object of the present invention is to provide a method for constructing an assembling building material without a scaffold.
[0011]
Further, the present invention enables almost all operations included in the entire construction process from assembling of assembled building materials to attachment of the building to a structure to be performed on a jig above the ground, It is an object of the present invention to provide a method for constructing an assembling building material without scaffolding, which can shorten the total work time and enhance the safety of work at a high place.
[0012]
[Means for Solving the Problems]
The method of constructing an assembling building material without scaffolding according to the present invention is a method of assembling assembling building materials into a construction method by transporting the erected assembled building material to a construction height and attaching it to a building structure. It has a jig that can be transported to a high place, and transports the assembled building material to the construction high place by lifting the jig that supports the assembled building material by connecting it to the assembled building material, The mounting of the assembled building material is performed while the assembled building material is connected to the jig, and the jig is separated from the assembled building material after the assembled building material is mounted on the structure of the building.
[0013]
According to the present invention, the work of transporting the assembled building material on the jig to the construction height is performed by lifting the jig that supports the assembled building material by connecting it to the assembled building material. The strength required for directly lifting it is no longer required. For this reason, it is sufficient to give the assembled building material the original strength as a building material, and it is not necessary to use an extra reinforcing material such as a reinforcing material or a tension material as seen in the preceding example 2, and the material cost is accordingly reduced. In addition, the increase in construction costs due to the increase in the weight of the construction materials and assembly materials can be suppressed. In addition, the present invention performs the mounting of the assembled building material on the structure of the building while the assembled building material is connected to the jig, and separates the jig from the assembled building material after the mounting of the assembled building material on the structure of the building. Therefore, it is possible to easily attach the assembled building material transported to the construction height place to the structure of the building while hanging it through the jig, and furthermore, it was used to transport the assembled building material. Later jigs can be reused separately from the assembled building materials. The state in which the jig supports the assembled building material includes not only the state in which the entire jig is completely supported by the jig, but also the part in which the assembled building material protrudes from the jig. The meaning includes the case where the part is less than half.
[0014]
In the present invention, it is desirable that the erection of the assembled building material on the jig be performed in a work space secured on the ground below the construction height, and by doing so, the assembled building material laid on the jig can be obtained. It can be immediately lifted to a construction height and attached to a building structure. Therefore, it is not necessary to move the assembled building material on the jig to another place and then to transport it to a construction high place.
[0015]
In the present invention, it is preferable that the work of assembling the assembled building material on the jig includes the operation of positioning each part of the assembled building material using the alignment mechanism provided in the jig. According to this, the jig used for laying the assembled building material itself has a function of improving the assembling accuracy of the assembled building material, so that the laying work on the jig can be accurately performed in a short time. It will be possible to shorten the total time of the non-scaffold construction method.
[0016]
In the present invention, it is preferable that the lifting operation of the jig connected to the assembled building material is performed by connecting and pulling up a cord body to an end of the jig connected to the whole of the assembled building material. For example, it is not only possible to lift with a crane, a hoist, or human power, but also, during the lifting work, the jigs that are assembled and overlapped with the whole assembled building materials are pulled up with a rope, so the strength required for lifting is reduced. It is only required for fixtures, and such building materials are not required to have such strength. For this reason, it is only necessary to give strength to the assembled building material as a building material, and it is not necessary to use an extra reinforcing material such as a reinforcing material or a tension material as seen in the preceding example 2, and the material cost and the manufacturing cost are accordingly reduced. In addition, an increase in construction costs due to an increase in the weight of assembled building materials can be suppressed.
[0017]
In the present invention, it is desirable that the jig is a frame, and that the frame is mounted on a support base on the ground so as to lay the assembled building material on the jig in a state of being floated from the ground. According to this, there is an advantage that the worker can perform an assembling operation on the jig while maintaining a comfortable posture, and an assembling building material in which the jig is connected immediately after the jig is lifted. A situation such as damage due to contact with the ground is less likely to occur.
[0018]
In the present invention, the assembled building material is composed of a plurality of panel materials as the above-mentioned parts, and an underlying structure that joins a plurality of panel materials arranged in parallel on the above jig. And a base structure that couples the plurality of louver members arranged in parallel on the jig.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is an exploded perspective view showing a jig and parts of an assembled building material to be used in the method for constructing a scaffold according to an embodiment of the present invention. FIG. 2 is a perspective view of a jig coupled to the assembled building material. FIG. 4 is an explanatory view showing a state of transportation to a construction high place, and FIG. 4 is an explanatory view showing an operation of separating a jig from an assembled building material and a separated jig.
[0020]
As shown in FIG. 1 or FIG. 2, the assembled building material 1 includes a plurality of rectangular panel materials 2 as parts and a plurality of base structures 3 formed of channel materials for connecting the panel materials 2. Have. Further, the jig 4 includes a rectangular frame 41 and a cross-shaped frame, and a tying member 43 formed of a belt dispersed at a plurality of positions is attached to the jig 4, and a corner portion of the rectangular frame 41 is provided. At a required position on the side and the side, there is provided a positioning mechanism 44 which can fit and position the panel material 2 as a part. The positioning mechanism 44 in the illustrated example has a function of positioning the panel member 2 by fitting the corner of the panel member 2. Further, the rectangular frame 41 is provided with a hook 45 for lifting. In addition, it is preferable to provide a damage preventing member such as a fault, a patch cloth, rubber, a soft resin plate, or a battens on the upper surface of the frame 41 which comes into contact with the assembled building material 1 so as not to damage the assembled building material 1.
[0021]
The jig 4 is a work space secured on the ground below the construction height of the assembly building material 1, and is mounted on a support base 5 as shown in FIG. At this time, it is desirable to set the height of the jig 4 to a height at which the worker can work in a comfortable posture. The panel material 2 and the base structure 3 as parts of the assembly building material 1 are transported from the factory to the work space where the jig 4 is installed without being assembled. For this reason, transportation costs are reduced compared to transporting assembled building materials assembled in a factory.
[0022]
In the work space, the erection work for assembling the assembled building material 1 on the jig 4 is performed. In this laying work, a required number (three in the example) of panel materials 2 are fitted into the positioning mechanism 44 of the jig 4 and arranged side by side as shown by arrows in FIG. This is done by deploying the body 3 and joining the panel materials 2 together. In this ground work, the plurality of panel members 2 are positioned and lined up with high precision by the positioning action of the positioning mechanism 44. Therefore, the assembling is performed by combining the panel members 2 with the base structure 3. The assembling accuracy of the building material 1 is a sufficiently satisfactory accuracy. When assembling the assembled building material 1 on the jig 4, it is not necessary to reinforce the assembled building material 1 to a strength required when lifting the assembled building material 1 itself.
[0023]
After assembling the assembled building material 1 on the jig 4, an operation of connecting the jig 4 to the assembled building material 1 is performed. This joining operation is performed by binding the ground structure 3 of the assembled building material 1 laid on the jig 4 with the binding tool 43 of the jig 4 as shown in FIG. If necessary, the end of the base structure 3 may be bolted to a bracket 46 mounted on the jig 4 as shown in FIG. In this case, it is desirable to use a binding device having a clip mechanism that can perform connection and disconnection with a single touch, in order to enhance workability and increase the connection reliability between the jig 4 and the assembly building material 1. .
[0024]
After the assembly building material 1 is detachably connected to the jig 4 using the binding tool 43 or the like, an operation of transporting the assembly building material 1 to a construction height is performed. This transfer operation is performed by lifting the jig 4 connected to the assembled building material 1. FIG. 3 shows a state in which the jig 4 connected to the assembled building material 1 is being lifted. In the illustrated example, a tension wire 47 is installed on a pair of hooks 45 at the ends of the jig 4. The jig 4 is lifted by pulling up the rope 62 while the hook 61 connected to the rope 62 of a crane or another lifting machine (not shown) is locked to the cable 47. In this embodiment, since the assembling of the assembled building material 1 on the jig 4 is performed in the work space below the construction height, the work of lifting the jig 4 and transporting the assembly building material 1 to the work place at a high place is performed. It is only necessary to lift the ground immediately after it is laid. Therefore, there is no need for an extra operation of moving the assembled building material 1 laid on the jig 4 to another place and then transporting the assembled building material 1 to a construction high place. In the lifting operation, the whole of the assembled building material 1 overlaps with the jig 4, and a plurality of portions of the assembled building material are dispersed and connected to the jig 4 by the binding tool 43. Only the jig 4 is required, and the assembled building material 1 is required only to have strength as a building material, but not required to directly lift the assembled building material 1.
[0025]
After the jig 4 combined with the assembled building material 1 is lifted and transported to a work place at a high place, an operation of attaching the assembled building material 1 to a structure of a building is performed. That is, as can be seen from FIG. 4, the worker M who has been waiting at the construction height places the assembled building material 1 on the structure 8 of the building while the assembled building material 1 is connected to the jig 4. In this manner, when the assembled building material 1 is attached to the structure 8 of the building, the assembly building material 1 is supported by a special support machine, or a plurality of workers lift the assembled building material 1, resulting in a danger of labor and labor. Such an operation is not required, and one or a small number of workers can attach the assembled building material 1 to the structure 8 of the building in a short time, in a reliable manner, and safely.
[0026]
After attaching the assembled building material 1 to the building structure 8, as shown in FIG. 4, the worker M releases the binding state by the binding tool 43 of the jig 4 or the base structure joined to the bracket 46. The jig 4 is separated from the assembled building material 1 attached to the structure 8 of the building by releasing the end of the jig 3, and the separated jig 4 is separated from the structure 8 of the building as indicated by an arrow A. Release and hang to the lower work space. The jig 4 hung in the work space is prepared for the next erection of assembled building materials.
[0027]
The panel material 2 to be used in the embodiment described above includes, for example, a plate-shaped body such as an aluminum punched metal, a plastic plate, and a steel plate. It is used as an outer wall material, a waistboard and the like.
[0028]
FIG. 5 is an exploded perspective view showing a jig and parts of assembled building materials which are other objects to be used according to the embodiment of the present invention, and FIG. 6 is a perspective view of a jig coupled to the assembled building materials. It is.
[0029]
In this case, the assembled building material 1 has a plurality of louver materials 2 ′ as parts and a plurality of foundation structures 3 ′ made of a channel material for connecting the louver materials 2 ′. . Further, the jig 4 includes a rectangular frame 41 and a cross-shaped frame 42, and a binding device 43 formed of a belt is attached to a required portion thereof, and a corner portion or a side of the rectangular frame 41 is provided. A required position of the part is provided with a positioning mechanism 44 'capable of fitting and positioning an end of the louver material 2' as a part. The positioning mechanism 44 in the illustrated example exerts a function of positioning the panel material 2 by fitting an end of the louver material 2 ′. Further, the rectangular frame 41 is provided with a hook 45 for lifting.
[0030]
The jig 4 is a work space secured on the ground below the construction height of the assembling building material 1, and is mounted on a support base 5 as shown in FIG. At this time, it is desirable to set the height of the jig 4 to a height at which the worker can work in a comfortable posture. The louver material 2 ′ and the base structure 3 ′ as parts of the assembled building material 1 are transported from the factory to the work space where the jig 4 is installed without being assembled. For this reason, transportation costs are reduced compared to transporting assembled building materials assembled in a factory.
[0031]
The point that the work space is secured below the construction height, the point that the assembling of the assembled building material 1 is performed on the jig 4 installed in the work space, and that the erection work is performed, and that the assembled building material 1 is laid on the jig 4 The operation of joining the jig 4 to the assembling building material 1 using the tying tool 43 or the like is performed. After assembling the assembling building material 1 to the jig 4 using the tying tool 43 or the like, the jig 4 is lifted to assemble the assembling building material. 1 to carry out the work of transporting the building material 1 to the construction height, attaching the assembled building material 1 to the structure 8 of the building at the construction height while keeping the assembly building material 1 coupled to the jig 4, After attaching the assembled building material 1 to the structure 8, the jig 4 is released from the assembled building material 1 attached to the building structure 8 by releasing the binding state of the jig 4 by the binding tool 43, and separation. For the point at which the jig 4 is suspended to the lower working space, see FIGS. It is the same as the embodiment described Te, and a detailed description thereof will be omitted to avoid duplication of description.

【The invention's effect】
As described above, the method for constructing an assembling building material without scaffolding according to the present invention includes supporting the assembling building material with the jig by joining the jig to the assembling building material laid on the jig, and then lifting the jig. Because it is transported to a high place, it is not necessary to give the assembly building material enough strength to withstand lifting, and not only is there no need for extra reinforcing material to give such strength to the assembly building material. Since the base structure does not need to provide such strength, it is possible to reduce the number of members required for the assembly building material, thereby reducing the material cost and the manufacturing cost. Since the weight is also reduced, an outstanding effect is achieved in that the load on the building structure after the assembly building material is attached to the building structure is also reduced. In addition, when transporting assembled building materials to construction sites with a crane, it is less likely that the assembled building materials will swing and interfere with the ground or the structure of the building during lifting, reducing damage during lifting of the assembled building materials. It becomes possible to do.
[0034]
In addition, since most of the work from assembling building materials to attaching them to the structure of the building will be performed on the ground work space, the total time for work at heights will be shortened, and safety will be improved accordingly. Become.
[0035]
Furthermore, if the assembling construction material is laid on the jig by using the alignment mechanism provided on the jig, the jig itself exhibits a function of improving the assembling accuracy of the assembling construction material. The ground work on the tool can be performed accurately in a short time.
