BACKGROUND OF THE INVENTION [0001] [Technical Field of the Invention The present invention is, for example, those related to the laying how suitable deck plates used in forming the floor of a building consisting of steel construction, etc. is there. 2. Description of the Related Art Conventionally, a steel deck plate used as a formwork or floorboard for forming a floor has generally been laid as follows. As shown in FIG. 5, after the columns 1, the girders 2, and the girders 3 were installed, a predetermined number of deck plates 4 were spread, and each deck plate 4 was welded to the girders 2 and the girders 3. [0003] A construction method is also used in which the deck plate 4 and the beams 3, 3 are integrally unitized. In this method, the deck plate 4A disposed between the small beams 3, 3 is unitized integrally, and this is joined to the large beams 2A, 2B. After this, the small beams 3 on both sides and the large beam 2 outside
A plurality of deck plates 4B and 4C were spread and welded to the portion between C and 2D as in the conventional case. [0004] In addition, a deck plate 4 and small beams 3,
There is also a construction method in which not only 3 but also the girders 2 are unitized.
This is a method in which the deck plate 4 and the small beams 3, 3 arranged between two adjacent girders 2A, 2B are integrated with the girders 2A, 2B in advance to form a unit. The unitized one is suspended between the upright pillar 1 and the girders 2C, 2D, and joined. [0005] The present Invention is to Solve However, the laying how the conventional deck plate as described above, there are the following problems. First, in the method of laying a large number of deck plates 4, it takes time and effort to lay and weld. In the method of uniting the deck plate 4A and the beams 3, 3, only the deck plate 4A between the two beams 3, 3 can be unitized. This is the deck plate 4 on both sides of the two beams 3
If units B and 4C are unitized, the deck plates 4B and 4C in this portion will protrude from the small beams 3 in a cantilever state. For this reason, a large number of deck plates 4B and 4C must be laid on both outer portions of the two small beams 3 in the same manner as in the conventional construction method, and the problem that the construction is troublesome cannot be completely solved. . In the construction method in which the deck plate 4 and the girders 2A and 2B are also unitized, the girders 2A and 2B are already installed in the span adjacent to this unit, so that the unit construction is performed only every other span. It could not be said to be a complete unit construction method, and the construction was complicated. [0008] The present invention has been made in view of the points mentioned above, and to provide a laying how the deck plate that can be efficiently laying deck plate. Means for Solving the Problems The invention according to claim 1 is:
A method of laying a deck plate, wherein at least one pair of small beams arranged in a portion surrounded by a plurality of beams ,
A deck plate laid between the pair of small beams,
A deck plate projecting from the pair of small beams in the direction of the girder is unitized in advance, and after providing a plurality of columns and beams to be bridged between the adjacent columns, the pair is formed.

After setting the lifted unit to a portion surrounded by the plurality of beams, the lifting jig is removed from the unit , and then the small beam and the deck plate are permanently joined to the beam. It is characterized by. [0010] By sandwiching and holding the end of the deck plate with the hanging jig in this manner, the deck plate for one span can be unitized. Also, by attaching small beams integrally to the deck plate,
The beam can be unitized. Moreover, the girder is not unitized, and therefore, the spans adjacent to each other can be similarly unitized. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a deck plate laying method according to the present invention and a hanging jig used therein will be described below with reference to FIGS. 1 to 4. explain. In each of FIGS.
Is a steel reinforced concrete column constituting a building frame, 11 is a large beam (beam) made of steel, 12 is a small beam made of steel, 13 is a steel deck plate, and 14 is a hanging jig. . As shown in FIG. 1, for example, two small beams are provided in a space for one span surrounded by four columns 10 and large beams 11, 11,. 1
2 and a deck plate 13 is spread over the upper surfaces of the girders 11 and the small beams 12. The deck plate 13 is unitized with respect to its construction. For example, both ends of the deck plate 13 are placed on two beams 11A and 11B. In the orthogonal direction, two large beams 1 are used to prevent interference with the four pillars 10 when suspended.
1C and 11D are unitized up to a portion inside a predetermined dimension (a portion surrounded by a thick line A in FIG. 1). As shown in FIG. 2, the suspending jig 14 includes a frame 15 and a holding member (holding portion) 16 provided on the frame 15 for holding the deck plate 13. The frame 15 has a pair of two channel members 17 having a length extending beyond the end of the deck plate 13. At the end of each channel member 17, an elongated hole 18 extending in the length direction of the channel member 17 is formed. On the other hand, as shown in FIGS. 2 and 3, the holding member 16 extends in a direction perpendicular to the two channel members 17 and has an angle member 19 having an L-shaped cross section. L-shaped cross-section holder 2 integrally provided on the lower surface
0, and the channel material 17 is passed through a notch 19 a formed at a predetermined position of the angle material 19. A bolt hole 21 is formed on the bottom surface of the angle member 19, and the channel member 17 and the angle member 19 of the holding member 16 are connected to the elongated hole 18 and the bolt hole 2.
The bolt 22 is inserted into the nut 1 and the nuts 23 and 24 attached thereto. By tightening or loosening these nuts 23 and 24 with each other, the bolt 22 is moved within the range of the elongated hole 18, and the holding member 1 for the channel member 17 is located at an arbitrary position.
6 can be positioned. In other words, the holding member 16 is movable in a direction approaching / separating from the end of the deck plate 13, and can be fixed at an arbitrary position. Next, a method of laying the deck plate 13 using such a hanging jig 14 will be described. First, as shown in FIG. 4, the deck plate 13 and the two small beams 12 are integrally welded to form a unit. Then, the holding members 1 on both sides of the hanging jig 14
At 6, the end of the deck plate 13 is sandwiched, thereby holding the unit of the deck plate 13. And
This is lifted by a lifting means such as a crane 26 via a suspension frame 25. On the other hand, the pillar 10 and the girder 11 are built in advance, and the suspended unit of the deck plate 13 is set on the girder 11A, 11B. Then, both ends of the small beam 12 of the unit and the large beams 11C and 11D are temporarily tightened at predetermined positions using bolts, joint plates and the like (not shown), and then the holding member 16 is slid outward to deck. Release from the end of the plate 13. The hanging jig 14 is used for hanging the next unit. Thereafter, as shown in FIG. 1, after the small beam 12 is fully tightened to the large beams 11C and 11D,
The deck plate 13 is welded to A, 11B, 11C, and 11D. As a result, the installation of the deck plate 13 is completed. Thereafter, a predetermined number of deck plates 27 are laid in the remaining gap portions in the same manner as in the conventional method, and are welded to the large beams 11 and the small beams 12. This completes the laying of the deck plate 13 for one span, and thereafter, the other spans may be similarly constructed. According to the deck plate laying method described above, most of the deck plate 13 and the small beam 1 for one span are provided.

At the same time, work at high places is greatly reduced, so that work safety can be improved. In addition, since the small beam 12 and the deck plate 13 are configured as a unit, the large beam 11 is not necessarily unitized, and it is possible to similarly unitize adjacent spans.
Therefore, the construction can be performed continuously by repeating the same operation, and the efficiency can be improved. Further, since the holding member 16 of the hanging jig 14 is provided so as to be movable with respect to the frame 15, it is very easy to attach / detach the hanging jig 14 to / from the deck plate 13 and to minimize the refilling. The hanging jig 14 can be diverted in a short time, thereby also increasing the efficiency of construction. In the above embodiment, the column 10 is made of a steel-framed reinforced concrete, but may be of a steel frame or the like. Deck plate 1 to be unitized
There is no intention to limit the configuration of 3 itself, for example, it may be a corrugated steel plate, a flat plate shape, or a configuration incorporating other devices. Also, the range and shape of the deck plate 13 to be unitized are not limited to the above-described embodiment at all, and other configurations can be appropriately adopted. Other than this, any configuration may be adopted as long as it does not depart from the gist of the present invention, and it is needless to say that the above-described configurations may be appropriately selectively combined. No. As described above, according to the method for laying a deck plate according to the first aspect, the suspension jig is used to remove the small beam.
By sandwiching and holding the end of the deck plate projecting in the direction of the girder, the deck plate for one span can be unitized. Therefore, the labor and time required for mounting the deck plate can be saved,
The construction period can be shortened. At the same time, work at high places is greatly reduced, so that work safety can be improved. In addition, by attaching the beams to the deck plate integrally, the beams can be unitized.
Moreover, the girders are not unitized,
Units can be similarly formed in adjacent spans. Therefore, the construction can be continuously performed by repeating the same work, and the efficiency can be improved. [0031]
