Figure 3 shows a front view of the third type of steel structure connection type support according to the present invention. 3 (a) is a rod-shaped member in which the male thread is formed on the outer circumferential surface of the connecting portion 140, the upper end of which is continuously connected to the coupler 110, and the lower end of the yoke supporting portion ( An example of the connection portion 140b coupled to 130 is shown. Figure 3 (b) is an example showing that the yoke support 130 is composed of a U-shaped member having a flat bottom surface. 3 (c) shows an example in which the connection part 140b extends downwardly through the yoke support part 130, and the yoke support part 130 and the connection part 140b are coupled by a nut. will be. The nut for coupling the connection portion 140b and the yoke support portion 130 while screwing the connection portion 140b also has a function of adjusting the yoke support portion 130 up and down (up and down), so as below, 'height adjustment' Nut 150 '. 3 (d) illustrates an example in which a spanner binding hole 141 is attached or an insertion hole 142 is formed at a lower end of the connection portion 140b. Since the third type has a simple configuration, the manufacturing cost is significantly lower than that of the first and second types. In addition, when installing the beam-slab formwork 300, according to the first and second type, first joining the coupling hole 110 of the steel structure connection type support with the cheolgolbo and then yoke the front and rear of the connection portion The yoke support portion 130 is supported by the yoke support portion 130, but when the yoke is assembled, the yoke support portion 130 supports the yoke under the yoke when the yoke is assembled. By using the coupler 110 and the fixing device 120, the beam-slab formwork 300 can be easily installed by fastening and fixing the steel ball 200. In this case, as shown in FIG. 2 (b), when the yoke support part 130 is formed in a 'U' shape having a flat bottom surface, the yoke support can be more stably supported. On the other hand, the steel structure connection type support 100 shown in Figure 3 (c), (d), even if the height of the connecting portion 140b to produce a sufficient height of the yoke by tightening or loosening the height adjustment nut 150 The height of the yoke support part required at the construction site can be obtained by adjusting the part 130 up and down. In addition, using the example shown in Figure 3 (d), when the concrete structure, after curing the iron structure connection type support and formwork when dismantling the spanner binding hole 141 attached to the bottom of the connecting portion 140b tools such as spanners By disengaging or inserting an iron rod into the insertion hole 142 formed in the lower portion of the connecting portion 140b, the dismantling operation can be performed simply by turning the iron rod or the like.

(4) The fourth type.

Figure 4 shows a front view of the fourth type of support structure connecting steel structure according to the present invention. 4 (a) and 4 (b) show a gap in a pipe in which the coupler 110 protrudes upward from an upper end of the connecting portion 140 and is fitted into an extended portion of the coupler 110. Holder 160; It is configured to further include, the length of the extended portion of the coupler 110 is shown an embodiment of the fourth type configured to exceed the length of the spacer 160. However, FIG. 4A illustrates an example in which the connecting portion 140a is configured in a frame shape, and FIG. 4B illustrates an example in which the connecting portion 140b is integrally connected to the coupler as a rod.

The fourth type steel structure connection type support 100 is used when the beam-slab formwork 300 to be described later to be installed so as to surround the cheolgolbo 200 at intervals, the combination of the steel structure connection type support 110 Is to have a length exceeding the interval between the cheolgolbo 200 and the beam-slab formwork 300. That is, the length of the portion protruding above the formwork 311 of the formwork when the coupling of the coupling 110 is the distance from the formwork 311 of the formwork to the buried position of the lower flange 210b of the cheolgolbo It must be exceeded. At this time, the spacing retaining hole 160 is fitted to the coupling hole 110, the spacing holding hole 160 is the spacing of the formwork 311 and the lower flange of the cheolgolbo (210b) Tubular members having lengths in accordance with the specification shall be used. The reason why the coupler 110 is inserted into and installed in the spacing holder 160 is as follows. First, when the spacing holder 160 is placed on the formwork 311 of the formwork, the formwork is required. Keeping the installation interval of the precisely, and secondly, when the work to dismantle the beam-slab formwork 300 and the steel structure connection type support 100 after the concrete casting, curing, easily turn the coupler 110 To be able to pull it out.

2. System formwork installation structure for manufacturing SRC beams.

Figure 5 shows a first installation example of the system formwork installation structure for manufacturing the SRC beam according to the present invention. In the first installation example, the cheolgolbo 200, beam-slab formwork 300, the steel structure connection type support 100 is connected.

The cheolgolbo 200 is composed of the upper, lower flanges (210a, 210b) and the web (220). The cheolgolbo 200 is a part of the steel structure woven before the beam-slab formwork 300 is installed as being embedded in concrete when the SRC beam is constructed.

The beam-slab formwork 300 comprises a formwork 311 and a joist 313 supporting the formwork, and a yoke 313 arranged in the joist and the lattice form the see-saw form 310, the see-through formwork As the formwork which is vertically coupled to the 310 as the formwork 321 and the side-side formwork 320 consisting of a grid frame 322 for supporting the formwork, the side-side formwork 320 as a formwork to combine at right angles. It is woven into a slab formwork consisting of a formwork 331 and a joist 332 supporting the formwork and a yoke 333 arranged in a grid with the joist 332. In the first installation example shown in Figure 5 is an example installed so that the lower plate 210b of the cheolgolbo 200 is exposed from the lower surface of the SRC beam, the beam slab formwork 300 is the lower flange 210b of the cheolgolbo And it is installed so that the concrete pouring surface of the formwork formwork 311 continues to be flat.

The steel structure connection type support 100 may use any of the first type to the third type. Of course, when using a plurality of supports, depending on the situation, it is also possible to mix various types of steel structure connection type support. However, the yoke 313 of the formwork according to the type of the support structure connected to the steel structure should be considered to be different from the way of fitting to the support frame and the difference of the above method has been described above. The coupler 110 of the steel structure connection type support is the male threaded rod 111 of the coupler is bound with the lower flange 210b of the cheolgolbo, and the yoke 313 of the formwork is the steel structure It is installed to be supported by the yoke support 130 of the connection type support. The binding method of the coupling structure 110 and the cheolgolbo lower flange 210b of the steel structure connection type support is to allow the male threaded rod 111 of the coupling tool to penetrate the cheolgolbo lower flange 210b and then protrudes the nut. Fastening while tightening with a type fastener 120 can be used. At this time, after the concrete is poured and cured in the beam-slab formwork 300, when the beam-slab formwork 300 and the steel structure connection type support 100 are dismantled, the nut-type fixture 120 is embedded in concrete. In the place where the male screw rod 111 is removed, a hole is formed, but the hole may be left alone, but may be filled with cement mortar or the like. Meanwhile, as shown in FIG. 8, an accessory such as a square washer 121 is inserted into the upper surface of the cheolgolbo lower flange 210b and the iron structure connection type support 100 is moved outward of the cheolgolbo lower flange 210b. It is also possible to use a method of fastening without placing the cheolgolbo lower flange.

Figure 6 shows a second installation example of the system formwork mounting structure for manufacturing the SRC beam according to the present invention. Like the first installation example, the second installation example has a structure in which the cheolgolbo 200, the beam-slab formwork 300, and the steel structure connection type support 100 are connected. However, there is a difference that the second installation example is installed so that the cheolgolbo 200 is completely embedded in the beam without being exposed to the lower surface of the beam. In this case, the fourth type of steel structure connection type support 100 should be used, and once again, the coupling tool of the fourth type of steel structure connection type support is bound to the lower flange 210b of the cheolgolbo, but If you look at the formwork of the formwork 311 and the lower flange of the cheolgolbo is characterized in that it is inserted into the interval maintaining hole 160 in accordance with the interval. In order to be installed in the above manner, the length of the portion protruding above the formwork 311 of the formwork of the coupler 110 is embedded in the lower flange 210b of the cheolgolbo from the formwork 311 of the formwork. It should be more than the distance to the location. The reason why the coupler 110 is inserted into and installed in the spacing holder 160 is as described above.

In the system formwork installation structure for manufacturing the SRC beam can be used to reinforce the beam-slab formwork installation structure using the support jaw 400 and the support port 500 in the first and second installation examples.

The support jaw 400 is formed by protruding from the lattice frame 322 of the side-side formwork, the support port 500 has a top and front, the rear is open support base supporting the yoke 333 of the slab formwork (333) 510 and the upper end is integrally coupled with the support frame 510 and the lower end is composed of a support rod 520 that is coupled with the support jaw. The method of coupling the lower end of the support bar 520 and the support jaw 400 may take various methods. In the installation example of the support port 500 shown in Figure 5 is coupled to the nut 530 to the support rod 520, the male thread is formed, and after raising the nut 530 to the support frame 510 of the support port The support rod 520 is inserted into the support jaw 400 and the nut 530 is loosened again until it closely contacts with the support jaw 400 so that the nut 530 is firmly attached to the support jaw 400. As a result, the support port 500 is shown as an example installed so as to be firmly fixed between the side-side formwork 320 and the slab formwork 330. The structure of the beam-slab formwork 300 is connected to the support frame 510 of the support port by supporting the yoke 333 of the slab formwork while coupling the support port 500 to the support jaw 400 by the above method. I can reinforce it.

Meanwhile, as shown in FIGS. 5 and 6, the yoke 313 of the seeing die is configured to be longer than the width of the seeing die, and the yoke 313 of the seeing die and the lattice frame of the see side die ( It is further configured to include a turnbuckle 600 connecting the 322 can reinforce the installation structure of the beam slab formwork.

Slabs of two or more floors of steel-framed buildings are manufactured by placing reinforcing bars and pouring concrete on slab formwork woven flat to the upper planar surface of Cheolgolbo.

The cheolgolbo is composed of the upper, lower flange and the web. The cheolgolbo 200 is attached to the upper flange of the cheolgolbo to attach a sheath connector (stud), spiral, etc., and to tie the reinforcement to this and pour the concrete to integrate the horizontal force to the entire skeleton to increase the strength of the building Before the slab formwork is installed, it is installed in a structurally stable state.

The slab formwork 330 is composed of a formwork 331, a joist 332 for supporting the formwork, and a yoke 333 disposed in a grid with the joist. The slab formwork is installed so that the concrete pouring surface of the upper flange 210a of the cheolgolbo and the slab formwork 331 on the side of the cheolgolbo 200 flat.

The steel structure connection type support 100 may use any of the first to third types. In addition, depending on the situation, different types of steel structure connection type support 100 may be mixed as described above. The coupling hole 110 of the steel structure connection type support is coupled to the upper flange 210a of the cheolgolbo, the yoke of the slab formwork 333 is supported by the yoke support portion 130 of the steel structure connection type support To be installed.
