DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-weather construction method for a steel-framed multi-story building.

[0002]

2. Description of the Related Art As an all-weather construction method for a steel-framed multi-story building, a roof-push-up construction steel frame, in which a main roof structure is constructed in advance of a low-rise building and the main roof structure is pushed up for each steel frame, is used as a top floor. There has been known a top-floor slab preceding casting method in which a roof slab is preceded after a folding screen is built.

[0003] In all of these conventional examples, all measures are taken to prevent rainfall. In order to shield against rainfall, all-weather construction such as framing work, finishing work and equipment work after steel frame work is possible. Because there was no shielding against rainfall and wind, it was not possible to perform all-weather work on column-beam joints, etc., which occupy a large construction weight in steel frame work. That is, in these construction methods, welding work cannot be performed not only on a rainy day but also on a windy day, so that the construction period of the steel frame construction is extended accordingly. In addition, in the former method, a special steel frame is constructed by adding a steel frame section below the main roof structure while the main roof structure is raised, so a special lifting device is required and the cost is high. However, there is a problem that it lacks versatility. The latter method has the advantage that steel frame construction can be performed by a general laminating method, but the roof slab cannot be built until the steel frame construction up to the top floor is completed, so there is a problem that the construction period becomes longer, It was not suitable for high-rise buildings.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in consideration of the above points, and an object of the present invention is to perform on-site welding work, which occupies a large construction period weight in steel frame work, in the weather. Can be performed without being affected, shortening the construction period
An object of the present invention is to provide a versatile all-weather construction method capable of stabilization.

[0005]

The technical measures taken by the present invention to achieve the above object are as follows. That is, in the all-weather construction method for a steel-framed multi-story building according to the present invention, each time a steel frame is constructed with a plurality of stories as one section, each section roof surface is constituted by a waterproof floor provided on the top floor and a windshield is provided on the side. panel constitute sections wall attached to, for internal welding operations in this state, as steel erection progresses, the sliding up the windshield panel upward sections, wind
Nde write a <br/> curtain wall steel frame side which is opened by sliding up the explosion panel Te denominated, the curtain wall
The feature is that it constitutes the all-weather construction wall after steelwork .

Although various concrete structures can be adopted as the water stop floor, it is desirable that the water stop floor is constituted by a deck plate which is a main component (floor formwork). The windshield panel may be a temporary material dedicated to shielding rain and wind from falling down. However, it is preferable that a large unit of a panel for an outdoor wall of a tower be manufactured in advance and used as a windshield panel.

[0007]

According to the above construction, each time a steel frame is constructed with a plurality of floors as one section, a waterproof floor is provided on the top floor of each section of the steel frame to form each section roof surface, and a windshield panel is provided on the side. Because it is attached and forms each joint wall, it will not only be shielded against rainfall, but also will be shielded against side rain and wind,
The on-site welding work in steel construction can be performed without being affected by the weather. Also, as the steel frame construction progresses, the draft shield panel is slid up to the upper node, but sequentially from the lower node , that is, the draft shield panel is slid to the upper node.
Each time the windshield panel slides up,
Since the curtain wall is built on the released steel frame side,
With the curtain wall , all weather wall surfaces after the steel work are also configured in parallel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of an all-weather construction method for a steel-framed multi-story building according to the present invention will be described below with reference to FIGS. In the figure, reference numeral 1 denotes a tower or a steel beam used for lifting a steel frame 1 or the like. The construction of the steel frame 1 is based on the general laminating method, and a plurality of floors (for example, three layers) are
The sections are performed in order from the bottom.

Reference numeral A denotes a water stop floor provided on the top floor every time a steel frame is constructed. Each water stop floor A forms a knotted roof surface, and the inside is shielded from rain. Although various specific configurations can be adopted as the water stop floor A, in the illustrated embodiment, the deck plate 3 which is a permanent floor material (floor formwork) is laid in a watertight manner on the beam steel frame. To constitute the water stop floor A. Removable lids (not shown) are provided at openings such as the temporary openings a and staircases b for loading and unloading materials formed on the water stop floor A, and the openings are closed by the lids during rainfall. I have to do it. When the tower crane 2 is provided at a position penetrating the water stop floor A, for example, a mast of the tower crane 2 penetrating the tower crane opening c is provided with a skirt-shaped eave (rain shield) larger than the tower crane opening c. In the meantime, raining is performed so that rainwater does not enter during rainfall.

Reference numeral B denotes a windshield panel attached to the side surface of the steel frame 1. Each windshield panel B is formed by the windshield panel B, and the inside is shielded from falling down and rain and wind. Reference numeral 4 denotes narrow ventilation nets provided at the four corners of each joint wall. The ventilation net 4 serves to maintain the working environment when performing welding work and the like by performing internal ventilation, but impairs the rainfall and wind shielding function of the entire joint wall surface. It is formed as narrow as possible so as not to be present. The windshield panel B may be a temporary material dedicated to shielding against rainfall and wind, but in the illustrated embodiment, a panel made of aluminum or the like for the outdoor wall of the tower is made into a large unit, and this is used as a windshield panel. Used as B.

The panel large unit for the tower outdoor wall is shown in FIG.
As shown in the figure, a large number of panels 5b made of aluminum or the like are attached to the front surface of a steel base 5a framed in a lattice shape, and are suspended via a traverser 6 by a winch or a tower crane 2, As the steel frame construction progresses, it is slid up to the node above.

In the panel large-size unit shown in the drawing, a steel sheet base 7a is connected to the upper part of the base 5a, and an appealing sheet 7b to be used for advertisement or the like is attached to the front surface thereof. And appeal sheet 7
b is removed when constructing the tower outdoor wall, and is not an essential component for the large panel unit.

C is an aluminum curtain wall fitted with window glass. The curtain wall C is previously made into a large unit by an assembling operation at a low position (in the illustrated embodiment, the roof slab 8 in the low-rise section).
As the steel frame construction progresses, it is lifted by the winch or the tower crane 2 and is sequentially built from the lower node.
D is a windshield panel (large panel unit for tower outdoor walls)
After the slide-up of B, the safety net is attached to the side of the steel frame until the curtain wall C is built.

Next, the steps of the all-weather construction method for a steel-framed multi-story building will be described. As shown in FIG. 5A, the steel frame is constructed in one section, and the deck plate 3 on the top floor is laid in a watertight manner to constitute the water stop floor A. The water stop floor A constitutes each knot roof surface of the first knot, and the inside is shielded from rain. Thereafter, a windshield panel B (in this embodiment, a large panel unit for a tower outdoor wall prepared in advance is used as the windshield panel B) is attached to the side surface of the steel frame 1. Thereby, each node wall of the first node is configured, and the inside is shielded from rain falling down and wind. In this state, an internal welding operation (indicated by a two-point hatched portion) is performed. As shown in (b) of FIG. 5, a two-section steel frame is constructed. As in the case of section 1, the top floor deck plate 3 is laid in a water-tight manner to form a waterproof floor A,
The water stop floor A constitutes each knot roof surface of the second knot. Thereafter, the windshield panel (panel large unit for tower outdoor wall) B is slid up and attached to the side of the two-section steel frame to configure the second-section node walls. As shown in (c) of FIG. 5, an on-site welding operation is performed on the inside of the second section (the portion indicated by the two-point hatching). Next, the curtain wall C, which has been made into a large unit, is attached to the steel frame side of one section (shelter belt B).
And the curtain wall C constitutes an all-weather construction wall after the steelwork. Steps (1) to (4) are repeated, and finally, as shown in FIG. 5 (d), a windshield panel (a large panel unit for an outdoor wall of a tower) is placed at a predetermined position on the roof.
B is built to construct the outer wall of the tower (blindfold of rooftop facilities).

According to the above embodiment, not only is it shielded from rainfall from above, but also from horizontal rainfall and wind, so that the site that occupies a large construction period weight in steel frame work Welding work can be performed regardless of the weather. In addition, since a large unit of a panel for an outdoor wall of a tower, which is used as a blindfold for rooftop facilities, is prepared in advance and used as a windshield panel B, the present material is effectively used and economical. The outer wall can be constructed quickly and safely.

In the above-described embodiment, the windshield panel B is divided into four planes around the building to form a plane. However, when a tower-like building with a short span is to be constructed, it is shown in FIG. As described above, the windshield panel B may be formed in a tubular shape surrounding the building, and may be slid up. In a tower-like building having a short span, it is also possible to construct a steel frame with the water stop floor A attached to the steel frame 1 in advance.
