Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention mainly relates to a floor panel used as a floor on the second floor.

Conventional technology Conventional prefabricated houses, especially on the second floor of apartments,
First, pass the floor beams between the tops of the first-floor frame or pillars installed at the site, attach joist bridges to the floor beams that are parallel to each other, and attach tan buckle braces to correct the building street. , The floor material was pasted to the joists on the floor. In addition, a field bridge is attached to the lower surface of the jota bridge, and a ceiling plate is attached to the ceiling field edge attached to the lower surface of the field bridge to construct a ceiling.

Problems to be Solved by the Invention In the above conventional floor structure, installation of joist bridges and installation of joists and braces are all performed on-site, and therefore there is a drawback that the number of on-site construction steps becomes extremely large. ing. In addition, these joists, joists, braces, etc. are brought into the site as separate parts, and moreover, the metal fittings for attaching the joists and joists are required, and the number of parts brought into the site becomes very large. There is a drawback that their management is also very complicated.

The present invention eliminates the drawbacks of the conventional floor structure, and only needs to bring the floor panel produced in the factory to the site and install it, so that the man-hours of the site work can be significantly reduced. The floor panel that can be used is provided.

Means for Solving the Problems In order to achieve the above object, in the present invention, a joist bridge is passed between beam members parallel to each other that are passed to the frame of a building, and a floor base plate is attached on the joist bridge. Attaching joists and passing a brace across the beam members on the lower side of the joist bridge, and the beam members, joist mechanism and braces form an integral panel in advance. Is.

Action The floor panel (14) configured as described above is factory-produced in advance and brought into the site as it is, and as shown in FIG. 4, it is placed on the frame (13) (13) of the building and installed. It is what is done.

Embodiment Hereinafter, the structure of the present invention will be described based on the illustrated embodiment. In FIGS. 1 and 2, (1) and (1) are beam members made of channel steel, respectively. Beam material (1)
(1) is arranged in parallel so that the groove portions between the flanges (2) and (2) face each other. Between the beam members (1) and (1) arranged in this way, joist bridges (3) (3) ... Composed of C-channels are provided at both ends thereof with the web (4) of the beam members (1) (1). ) Fixed to the upper half and passed in parallel at appropriate intervals. And, on these joisters (3), beam members (1) (1)
Joist made of 3 square pipes in the direction parallel to (5)
(5) (5) are passed with an interval between them.
(6) is a floor base plate, and this floor base plate (6) is attached to the joists (5), (5) ... Further, it is surrounded by a pair of joist bridges (3) and (3) on both ends of the beam materials (1) and (1) passed between the beam materials (1) and (1), and a joist bridge (3) in the middle part. Each space (7) (7) has a mounting plate (8) at a corner of the space (7) (7).
(8) fixed and these mounting plates (8)
Compression type braces (9) and (9) made of square pipes are passed and fixed across the space (8).

Further, on the lower surface of the joist bridge (3) in the middle of the joist bridges (3) and (3) on both ends of the beam (1), there are field bridges (10) and (10).
(10) is installed and this field ensemble (10) (10)
Three ceiling fields (11), (11) and (11) parallel to the beam (1) (1) are attached in parallel to each other across the lower surface of (10) at intervals.

In this embodiment, the beam members (1) (1) and joist (3) are used.
(3) ... and joists (5) (5) ... joist mechanism (1
2), the brace (9) (9), the field edge receiver (10), and the ceiling edge (11) are integrated into a panel (14) in advance at the factory,
As shown in FIG. 4, it is placed and fixed between each of the frames (13) and (13) or between frames such as columns. FIG. 3 shows a concrete fixing structure of such a beam member (1). The beam member (1) is fixed to the first floor frame (13) by bolts (15), Further, the lower surface of the shaft assembly (16) on the second floor is fixed to the upper surface of the beam (1) with bolts (15).
Reference numerals (17) and (17) denote outer wall panels attached to the outside of the frame sets (13) and (16). A ceiling plate (18) is fixed to the lower surface of the ceiling rim (11) by nailing or the like.

In the embodiment shown in FIG. 1 and FIG. 2, the floor panel (1
Although it is shown that it is attached to 4), in the embodiment of FIG. 5, the field bridge (10) and the ceiling field (11) are not fixed, but they are removed so that they can be installed on site and made into a panel. It shows what was done.

Effect of the Invention As described above, according to the present invention, since the beam material, the joist structure including the joists and joists, and the brace form an integrated panel in advance, such a panel is installed on the beam on site. It is only necessary to bring in and install it on the frame as it is, and compared to the conventional one where each member was individually installed on site, the number of man-hours on site work was greatly reduced and the number of parts on site was also reduced. Therefore, it is possible to easily manage parts. In addition, since a brace is also integrally formed in advance to hold a perfect rectangular shape, if such things are arranged side by side, the building will naturally come out, so there is no need to make corrections on site. In particular, in this invention, since the brace is attached to the joist between the joists on the lower side of the joist, even when the floor under board is directly hit on the joist, the braces do not lift the under board, and such a brace is used. There is an advantage that it is not necessary to form a groove on the back surface of the base plate or to provide something like a spacer between the base plate and the joist. Furthermore, as shown in the example, if the floor base plate is also attached integrally,
There is no need to specially install a scaffolding board for work as in the conventional case, and the scaffolding board can be used as it is as a work floor without any danger.
