Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a scaffold-free construction method for exterior wall steel plates.

"Problems to be solved by conventional technology and inventions" In recent years, weather-resistant steel plates have been used for the exterior walls of skyscrapers, nuclear power plant buildings, rack warehouses, etc., and the scale of these buildings has gradually become taller and larger. It's coming.

By the way, the conventional exterior wall steel plate has a T-groove 1 in the center of a rectangular steel plate 11, as shown in FIGS. 8 and 9.
1 ₃ is formed with T-groove-shaped engagement edges 11 ₁ , 11 ₂ on both sides. Therefore, when built on a steel frame to which the furring material 21 has been attached in advance, the T-groove 11 in the center
₃ and one engaging edge 11 ₁ are fixed to the furring material 21 with a mounting bracket 12, and to connect adjacent steel plates to each other, as shown in FIG.
Insert the other engaging edge 11 of the already attached one engaging edge 11 ₁ diagonally (), rotate the engaging edge about the axis toward the furring material 23, and direction to engage the engaging edges with each other (), then attach the mounting bracket 1 as described above.
2 to the furring material 21 ().

However, because of this procedure, external scaffolding is indispensable, and when the external wall steel plates are hoisted to a high place using input such as a winch, they must be pasted up one by one, and the following problems arise when doing so: arise.

Steel plates are easily scratched.

Frequent replacement of joint materials for external scaffolding occurs,
Moreover, it is difficult to perform water stop treatment after refilling, which may cause water leakage.

In the case of transportation to high places and input, accidents such as objects falling or people falling are likely to occur, and it is expected that it will be extremely difficult to prevent such accidents.

Since the installation is done one by one with steel plates, increasing the overall precision requires a large number of management personnel and time.

When tensioning steel plates one by one, it is difficult to start tensioning from the middle stage, as the principle is to start from below the water. If there is a shed in a building undergoing frame construction, it becomes increasingly difficult to do so, resulting in large losses both in terms of process and cost.

The present invention seeks to solve these problems.

``Means for Solving the Problems'' The present invention comprises assembling a plurality of exterior wall steel plates, furring materials and panel vertical frames corresponding to these exterior wall steel plates,
The required number of large panels are assembled in advance, and these large panels are erected onto a steel frame, arranged vertically and horizontally at small intervals, and then joined to the steel frame using frame materials and panel vertical frames. , horizontal joint drainage materials are arranged between the upper and lower adjacent ones, and these horizontal joint drainage materials are connected to each of the furring members through the small intervals, and vertical joint materials are arranged between the left and right adjacent ones, respectively. The vertical joint materials are arranged and connected to each of the panel vertical frames through the small intervals.

``Function'' Since the structure is as described above, a large panel made by assembling a plurality of exterior wall structure plates, cladding materials, and panel vertical frames can simplify the erection, and can also be used to reduce the number of cladding materials and panel vertical frames. It is possible to assemble the main body by simply joining the panels to the steel frame, and the small spacing between the large panels allows the horizontal and vertical joints to be joined to the frame material and the vertical panel frame. They thus enable assembly operations on the side of the steel frame or inside the large panels, obviating the need for external scaffolding and achieving the intended purpose.

Embodiment FIGS. 1 to 7 show an embodiment of the present invention.

In this embodiment, the steel frame 2 is erected, and the required number of large panels 1 for the outer wall are assembled on the ground, as in the conventional method.

As shown in FIG.
5 external wall steel plates 11 with a width of 0.6 m and a height of approximately 1.7 m.
On the stage S of the assembled frame body, the channel furring material 21 and the panel vertical frame 22 are used as a base body, and are connected and integrated using the mounting fittings 12 to form them. At this time, the stage S enables assembly work on the back side.

The required number of large panels 1 assembled in this way are
As shown in Fig. 2, it is hoisted by a crane C and erected vertically onto the steel frame, and each of the frame members 21 and panel vertical frames 22 are assembled into the steel frame 2 using plates 24, etc. (Figs. 5 to 7) ). At that time, between the adjacent large panels on the top, bottom, left and right, and between the foundation concrete 5
(Fig. 2) and the large panel directly above it. Please note that welding, bolts and
Any appropriate existing means such as nuts etc. may be taken. In the figure, 23 is a steel column.

Then, as shown in FIG. 3, horizontal joint drains 4 are interposed between adjacent large panels on the upper and lower sides and at small intervals between the foundation concrete and the large panels. As shown in Figure 7, this horizontal joint drain is made by bending a long and thin steel plate to form an inclined part in the middle, an upright part on the inside, and a hanging part on the outside. It is fixed to the furring material 21 or the foundation concrete 5 with bolts 41 or the like. In addition, door members 6 and 7 are attached to the upper and lower ends of each large panel to close them off, and a door holder 8 made of a steel plate is attached to the upper end. Although not shown, necessary vertical gutters and the like are also installed at this time.

Next, as shown in FIG. 3, the vertical joint material 3 is lifted up by a crane C or the like and attached between the adjacent left and right large panels, thereby connecting the large panels to each other. As shown in Fig. 6, this vertical joint material 3 is made by bending a long and thin steel plate to have a trapezoidal cross section and the same length as a large panel. The vertical joint material 3 is installed by attaching sealing material 3 to the engaging edges 11 ₁ and 11 ₂ of the adjacent left and right large panels, respectively, as shown in FIG.
5, and the edges of the vertical joint material are brought into contact with the sealing material, and the mounting bolts 3 that stand up from each mounting hardware 31 are attached.
2 loosely inserted between the panel vertical frames 22 of the left and right large panels, fit the bolts 34 onto each mounting bolt, bring both ends of the corresponding bolts into contact with the inner surface of the panel vertical frame, and then tighten the nuts 33. Align and tighten.

Finally, although not shown, install the eaves gutters and complete the process (Figure 4).

"Effects of the Invention" According to the present invention, the required number of large panels are pre-assembled by assembling a plurality of exterior wall steel plates, furring materials, and panel vertical frames, which greatly simplifies the construction work. At that time, the main body can be assembled by simply joining the frame material and the panel vertical frame to the steel frame, and since there is a small interval between the large panels, the horizontal joint material and the vertical joint material can be installed through the small interval between the large panels. It can be joined to the steel frame and the panel vertical frame, making it possible to assemble it on the side of the steel frame, that is, inside the large panel.
External scaffolding can be made unnecessary, work can be made easier, and the number of workers can be significantly reduced.

In addition, since external scaffolding is not required, the inconveniences associated with external scaffolding can be eliminated, safety can be greatly improved, water-tightness can be ensured, and the accuracy of installing external wall steel plates can be improved. Scratches can be reduced, and a complete check can be performed on the ground.

Furthermore, construction can be carried out from the middle level as desired, improving construction efficiency, shortening the construction period, and significantly reducing costs. In addition, vertical gutter installation can be done at the same time, reducing the number of work steps required, and even large diameter gutter installations can be carried out safely, achieving the intended purpose.
