Abstract

PURPOSE:To make a large-sized scaffolding unnecessary by assembling, at the ground, external wall materials surrounding a high-rise building structure body into an external wall unit in a square-case shape and hoisting the assembled units one after another until the stacked wall units reach the uppermost story, and by fixing the same thereto. CONSTITUTION:A building structure body 1 is constructed of four steel columns 4 positioned in the front and the rear and in the right and the left, and structural steels for structure bodies 3 comprising beams and trusses that are connected thereto. At the uppermost story of the structure body 1, a twin-jack 5 and an oil-hydraulic pump 6 are installed. A control panel 9 is installed on the ground 8 and hoisting of a hoisting wire hung down from the twin-jack 5 is controlled thereby. At an assembling stand 12 on the ground, external wall materials are integrally assembled into an external wall unit 13 so that the building structure is surrounded by the wall unit. The wall units so assembled are hoisted one after another along the exterior of the building structure body 1 and are fixed thereto. By repeating the same process of works, the fixing of the wall units reaches the uppermost story of the building structure body 1. Thereby installation of a large-sized scaffolding becomes unnecessary even for a building of high-rise structure.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for attaching an exterior wall to a building such as a tower parking lot.

[Prior Art] When constructing the exterior walls of a building such as a tower parking lot, large-scale work is carried out around the building structure, which is the steel frame structure of the building, at a height corresponding to the height of the building structure. Conventionally, it has been common practice to erect scaffolding and attach panel-shaped exterior wall materials that are lifted up by a large crane or the like one by one to the building structure one by one from the bottom to the top using the above-mentioned work scaffolding. is being carried out.

[Problems to be solved by the invention]However, in the case of the above conventional method of exterior wall construction, , It takes a large amount of time to erect the scaffolding and remove the WI, and construction may be difficult if the space between the scaffolding and the adjacent property is narrow. Since the work is pasted one by one, the work efficiency is poor and requires a lot of manpower, which takes a long time. There were problems such as the fact that it was dangerous because it was susceptible to

Therefore, the present invention eliminates the need for large-scale scaffolding, allows easy construction even for structures with narrow spaces between adjacent properties, shortens construction time, and improves safety. The purpose is to provide an excellent method for attaching external walls of buildings.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a cylindrical external wall having a required height by integrating external wall materials arranged on four sides so as to surround a building structure. Assemble the unit above ground, then lift the exterior wall unit along the building structure, stop lifting at a position that leaves an assembly space for one stage of exterior wall units at the bottom, and then Assemble the next exterior wall unit in the assembly space for 1 minute, add it to the upper exterior wall unit lifted earlier, and then
The method is characterized in that the external wall units are lifted and stopped, leaving one stage of the external wall units, and then the same steps are repeated in order to place the external wall units up to the top of the building structure, and each external wall unit is fixed to the building structure. This is the method for attaching the exterior wall of a building.

[Function] Since the external wall units assembled in a cylindrical shape above the ground are lifted and added one after another, there is no need for high-altitude work using large, tall scaffolding, and the work is safe with good workability. be able to perform work.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 7 show work procedures according to an embodiment of the method for attaching an exterior wall to a building according to the present invention, and the method according to the present invention includes:
Basically, it is arranged so as to surround a steel-frame structure 1 consisting of four steel columns 2 placed at four locations on the front, rear, left, and right, and structural members 3 such as beams and trusses that connect the steel columns 2. The exterior wall unit 13 is made by integrating the exterior wall materials on the four sides and assembling it on the ground in a headband shape.The exterior wall unit 13 is finished by finishing the joints while lifting it up one stage at a time along the building structure 1. The assembly of the outer wall units 13 and the addition of the outer wall units 13 to each other are performed on the ground.

To explain specifically, first, prior to the work of attaching the outer wall unit 13, the following work is performed. That is, as shown in FIG. 1, a building structure 1 is erected, and twin jacks 5 are installed as lifting machines at the four corners of the top of the structure via mounts 4, and each of the above-mentioned equipment is installed on the building structure 1. A hydraulic pump unit 6 for driving the twin jack 5 is installed via a temporary stage 7, and the hydraulic pump unit 6 is connected to a control panel 9 placed on the ground section 8 via control lines 9a and 9b. The lower end of the lifting wire 10 unwound from each of the twin jacks 5 is lowered to a required height from the ground part 8 and the building structure 1 is controlled by operating the control panel 9.
Place it at the four corners of the Next, as shown in FIG. 2, a single-tube scaffolding 11 with handrails is placed above the ground at a required height so as to surround the lowest part of the building structure 1, to a height equivalent to one level of the outer wall unit 13, which will be described later. Furthermore, an outer wall unit assembly frame 12 is temporarily installed on the ground part 8 so as to be located in the space between the single pipe scaffold 11 and the building structure 1.

After this work is completed, the outer wall unit 13 is installed using the method of the present invention. First, as shown in FIG. 3, the exterior wall materials are carried onto the assembly frame 12 and temporarily placed therein, and the exterior wall materials are arranged to surround the building structure 1 to form an exterior wall formed by integrating each exterior wall material. Assemble unit 13. In order to allow the exterior wall unit 13 to be lifted along the outside of the building structure 1, the exterior wall materials on the four sides are arranged in a headband shape so that it has a rectangular cylinder shape that conforms to the horizontal cross-sectional shape of the building structure 1. It is assembled as shown in detail in FIG. 9, which shows an enlarged plan view of section A in FIG. 3, and FIGS. 10 to 12. The lifting wires 10 unwound from the twin jacks 5 are attached to the lifting metal fittings 15 at the upper ends of the four lifting reinforcing members 14 made of angle members erected vertically at the four corners of the outer wall unit assembly stand 12. The lower ends are locked and each lifting reinforcing member 14 is set at the four corners.Next, the furring rims 16 are attached in multiple stages in the vertical direction between the adjacent lifting reinforcing members 14, and each of the lifting reinforcing members 14 is After checking the dimensions, on the outside of each rim 16,
The panel-shaped exterior wall materials 17 are attached, for example, with screws, and a portion of the corner formed between the exterior wall materials 17 is finished as necessary. In addition, when the outer wall material 11 is of a split type in the left and right direction, a vertical rim is provided in the middle of each rim 16 and the parts are added at this portion.

When the outer wall unit 13 is assembled on the assembly stand 12 as described above, then each twin jack 5 is hoisted and driven to lift each lifting wire 10 as shown in FIG.
At the same time, by winding up the outer wall unit 13, the outer wall unit 13 is lifted by one step in height and stopped, and then the lifted outer wall unit 13 is moved as shown in FIG. 13, which is an enlarged plane of section B in FIG. 4. The lower end position of each lifting reinforcing member 14 is temporarily fixed to the steel column 2 of the building structure 1 via a temporary fixing member 18. In this state, an exterior wall unit assembly space S sufficient for assembling one stage of exterior wall units 13 is not formed at the bottom of the lifted exterior wall unit 13, so as shown in FIG. The second stage outer wall unit 13 is assembled in the same manner as shown in FIGS. 10 to 12. In addition, at this time, as shown in FIG. 14 (showing an enlarged cross section of section C in FIG. 5), the lifting reinforcing material 14 of the second stage outer wall unit 13 is
The upper end is connected to the lower end of the lifting reinforcing member 14 of the first-stage outer wall unit 13 via a connecting member 19 to integrate the first-stage and second-stage outer wall units 13 in the vertical direction, and further,
At this time, horizontal filling work is performed on the joints between the outer wall materials 17 of the first-stage outer wall unit 13 and the second-stage outer wall unit 13.

In addition, when the exterior wall material 17 is a member such as a painted steel plate, the exterior wall material 17 is removed when the first stage exterior wall unit 13 is assembled.
Do not screw the lower end of the , and when joining the first and second tier exterior wall units 13, insert the lower exterior wall material 17 inside the upper exterior wall material 17, and then Make sure to screw it in place (taking up the overlap).

First stage external wall unit 13 and second stage external wall unit 13
After integrating, the temporary fixing of the first stage outer wall unit 13 is released, and then the outer wall unit 13 is lifted and added in the same manner as described above, as shown in Fig. 6. A predetermined number of stages (six stages in the figure) of the outer wall units 13 are lifted up to a predetermined position, and a predetermined outer wall unit assembly space S is formed at the lowest part.

In this state, all the furrings 1 in each outer wall unit 13
6 to the steel column 2 or structural material 3 of the building structure 1 via the mounting member.
Fix by tightening bolts, etc.

Furthermore, after removing the assembly frame 12, twin jack 5, hydraulic pump unit 6, control panel 9, etc., necessary openings 20 such as entrances and exits were provided in the lowermost outer wall unit assembly space S, as shown in Fig. 7. The exterior wall construction is completed by assembling and fixing the exterior wall unit 13, and then performing roof construction and installing a cap.

The above-mentioned work procedure is as shown in FIG.

In this way, in the present invention, the exterior wall unit 13 assembled in a headband shape is lifted up to one level from the above-ground part 8, and the next stage exterior wall unit 13 is assembled in the space below the lifted exterior wall unit and successively added. Therefore, the exterior wall work can be carried out without using a large scaffold corresponding to the height of the building structure 1 as in the past, and the work can be carried out even in a moat where the space between the building structure 1 and the neighboring land is narrow. In addition, the outer wall unit 13, which forms the outer wall, is shaped like a rectangular tube and can be attached to all four sides of the building structure 1 at the same time, making it much easier to construct than conventional methods and shortening the construction period. can be achieved. Furthermore, since the outer wall unit 13 is shaped like a rectangular tube, it can be stably arranged around the building structure 1, so it is less susceptible to the influence of wind during lifting, and is excellent in terms of safety.

In the above embodiment, the outer wall unit 13 is also made into a prismatic cylindrical shape in order to correspond to the prismatic cylindrical building structure 1. For example, if the building structure 1 is cylindrical, the outer wall unit 13 is made to correspond to the cylindrical shape. It is sufficient to make it cylindrical.Also, although the case where the outer wall unit is lifted with twin jacks is shown as an example,
It goes without saying that it may be pushed up using a jack, and that various other modifications may be made without departing from the gist of the present invention.

[Effects of the Invention] As described above, according to the method for attaching an exterior wall to a building of the present invention, the exterior wall unit assembled in a cylindrical shape at the ground level, which is the lowest part of the building structure, can be attached to the entire height of the building structure. By lifting up each stage and adding more until the end is reached, the following excellent effects can be achieved.

(1) Since there is no need to assemble large, tall scaffolds around the building structure, work can be carried out easily even on building structures where the space between adjacent properties is narrow.

(11) No need to work at heights using large scaffolding,
Work can proceed safely without being affected by wind.

(iii) Since the outer wall units are assembled in a cylindrical shape above the ground and are added together, it is easy to construct.
It is possible to shorten the construction period.
