Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flat deck and a device that can be assembled by separately molding a flat floor plate and a tree beam.

[0002]

[Prior art]

 As shown in FIG. 7, a conventionally used flat deck is an integrally molded product of a flat floor plate 5 and a tree beam 10 formed by bending a single plate 1.

[0003]

[Problems to be solved by devising]

 Since the above-mentioned conventional flat deck is an integrally molded product, the presence or absence of ribs or grooves, the size, the shape of the tree beam, the height, etc. of the flat floor plate are specified respectively, so they must be manufactured whenever necessary. In addition, there is a problem in that transportation and packaging are bulky.

In addition, since one plate is bent during manufacturing, not only the manufacturing process becomes complicated, but also the processing machine becomes large and it is difficult to improve the manufacturing efficiency.

[0005]

[Means for Solving the Problems]

 In this invention, however, the flat floor plate and the tree beam are separately manufactured and appropriately assembled, so that the above conventional problems are solved.

That is, the present invention is a flat deck in which bent portions at both ends of a flat floor plate having ribs are fitted into and fixed to upper openings of tree beams. In addition, a groove is provided on the flat floor plate parallel to the tree beam, and a plurality of ribs are installed in parallel at an angle to the groove. The tree beam is a bent side surface with a triangular shape, Has a narrow opening, and the upper edge is bent in parallel or at a right angle with the lower side.

Next, another invention is that a bent portion at both ends of a flat floor plate having ribs is fitted and fixed to an opening at an upper end of a tree beam, and a heat insulating material is interposed between the tree beam and the tree beam. This is a characteristic flat deck device, in which the bent portions at both ends of a flat floor plate having ribs are fitted and locked to the upper end opening of the tree beam, and the lower part of the reinforcing bar support plate is fitted and inserted into the upper end opening of the tree beam. The flat deck device is characterized in that the reinforcing bar is supported by an upper portion of the reinforcing bar support plate and a hook portion.

The flat deck of the present invention is used, for example, as a base deck of a concrete floor, but it is possible to construct a vast flat floor surface by sequentially assembling it. Therefore, although there are various types depending on the design, such as the rise on the floor of a building, it is possible to deal with the diversification of tree beams.

The flat deck of the present invention has the following features.

(1) Since it is a flat plate, it is not necessary to use wasteful concrete in terms of strength, the concrete can be reduced, and it can be used as a formwork method that replaces the conventional control panel.

(2) In principle, no support is required, and the material can be saved.

(3) Since it has a considerable strength, it can be used as a work passage after assembly.

(4) The bar arrangement on the surface can be made freely. (Using a flat deck rebar spacer saddle.) (5) If the height of the ribs on the flat floor plate is triangular, it will support the load and provide strength.

(6) By making each individual, the material mass is lightened, and the work is safe and easy.

(7) Many can be accommodated in a relatively small volume during transportation and packaging.

(8) For various span intensities, one type of span intensity can be used depending on the tree beam interval position.

(9) A flat deck with a heat insulating material can be easily produced in a factory.

[0018]

[Action]

 According to this invention, it is possible to easily supply a flat deck of a required length by manufacturing many types of tree beams.

The ribs and grooves have the necessary strength as they are and can be used for the passage at the time of construction, and since one component is extremely lightweight, work in high places can be performed easily and safely.

[0020]

Example 1 Two parallel side edges of a rectangular steel plate 1 are bent at right angles to form hooking edges 2 and 2, and grooves 3 and 3 are provided at a predetermined distance from the hooking edges 2 and 2, A plurality of ribs 4, 4 are formed in parallel at right angles to the grooves 3, 3 to form a flat floor plate 5. On the other hand, the center part of one square steel plate is used as the bottom plate 6 over a predetermined width, and the double bent parts 7, 7 are provided on both sides of the bottom plate 6, and then it is raised obliquely to form the triangular tube 8, and the upper end is formed. The edges are bent in parallel with the bottom plate 6 to form supporting portions 9 1, 9 to form a tree beam 10. The flat deck of the present invention can be obtained by fitting and locking the hooking edges 2 and 2 of the flat floor plate into the opening of the tree beam 10.

The flat deck of the present invention can be assembled to a desired length by sharing adjacent tree beams as shown in FIG.

In the above-mentioned embodiment, as shown by the chain line in FIG. 2, if the heat insulating materials 11 and 12 are respectively provided inside the tree beams and between the tree beams, the heat insulating material can be applied as a whole. .

[0023]

Second Embodiment Another embodiment will be described with reference to FIGS. 3 (a), 3 (b) and 4.

In FIG. 3 (a), a bottom plate 6 is formed in a central portion of one square mesh plate over a predetermined width, and double bent portions 7, 7 are provided on both sides of the bottom plate 6, and then the bottom plate 6 is raised obliquely. The triangular tube 8 is formed, and the upper edge is bent along the rising part of the above-mentioned slant to provide the bent parts 13 and 13, and the ends are raised almost vertically so that the grooves 14 and 14 are formed. The tree beam 10 is formed and the edges 14, 15 are provided in the grooves 14, 14. The hooks 2 and 2 of the flat floor plate 5 formed in the same manner as in the first embodiment are hooked in the grooves 14 of the tree beam 10 to assemble a flat deck. The flat deck can be used in the same manner as in Example 1, but a detailed description will be omitted.

The tree beam shown in FIG. 3 (b) is formed by bending the upper edge of the tree beam shown in FIG. 3 (a) inward without bending it outward to form vertical portions 16, 16.

[0026]

Third Embodiment The embodiment of FIG. 6 shows a bar arrangement.

That is, for each tree beam in FIGS. 1 and 4, a predetermined number of lower portions of the reinforcing bar support plates 17 are fitted and fixed, and the reinforcing bars 20, 19 are respectively inserted into the cutout portions (locking portions) 18, 19. It is the one that 20 was hooked. By inserting and fixing the lower portion of the reinforcing bar support plate 17, the reinforcing bar 20 can be supported at a predetermined height and arranged. In the figure, 21 is a through hole (concrete communicating hole).

According to the above-described embodiment, the height of the reinforcing bar can be easily regulated by the notch position of the reinforcing bar supporting plate 17, and the supporting bar can be arranged in the correct position, so that special technique or special operation can be performed in the bar arrangement. do not need. The free edges of the notches 18 and 19 are bent as shown by the chain line in FIG. 6 to prevent the rebar 20 from coming off.

[0029]

[Effect of device]

 According to this invention, since the flat floor plate and the tree beam can be assembled, there is an effect that a flat deck corresponding to a required length can be easily obtained by changing a mounting interval of the tree beams.

Further, since the two rectangular plates are separately molded, the apparatus can be downsized and the efficiency can be improved as compared with the case of integral molding.

Further, it is possible to reinforce the connection portion between the flat floor plate and the tree beam.
