Registered Utility Model No. 3090659 (all pages)

  This steel house is constructed by joining lightweight sections to each other using drilling tapping screws (hereinafter simply referred to as “screws”) or bolts and nuts, but the number of screws and the like becomes enormous, There is a problem that much time and labor are required for the joining work.

  In addition, in order to improve workability at the construction site, wall panels, floor panels, ceiling panels, roof panels, etc. are assembled in advance in the factory, and attempts are made to join them together at the site. There is no change in the number of screws that are sometimes required. For example, as shown in FIG. 14, a conventional floor panel is composed of end joists 61, side joists 62, floor joists 63, anti-rollers 64, wall supports 65 and the like made of lightweight steel having a cross-sectional groove shape. Joining each other to form a panel requires an enormous number of screws and the like, so even if it is manufactured in a factory, it takes a lot of labor and time. In other words, if various panels are produced at the factory, the work at the construction site is greatly simplified, but the production of the panels still requires a great deal of labor and time. It cannot be said that simplification, speed-up, and production cost are sufficiently reduced, and there is still room for improvement.

  Therefore, an object of the present invention is to provide a steel house capable of simplifying and speeding up construction work and capable of reducing manufacturing costs.

Such problems the invention of claim 1 for solving is disposed deck plate between the wall member against direction is a steel house floor body by using the deck plate is built.

  According to such a steel house, since the types of members constituting the floor body are greatly reduced, it is possible to simplify and speed up the construction work of the floor body, and thus simplify the construction work of the entire steel house. It is possible to reduce the manufacturing cost. In other words, in the conventional steel house floor, it was necessary to join a wide variety of members such as edge joists, side joists, floor joists, anti-rollers, wall supports, etc. using a huge number of screws, etc. In the floor of the steel house according to the present invention using the plate, such complicated work is not necessary.

In the present invention, the deck plate is a synthetic slab deck plate, wherein the floor body is ing to Da設concrete to the synthetic slab deck plate.

That is, the steel house according to the present invention has a synthetic floor slab as the floor body. If it does in this way, the sound insulation performance of a floor body will improve remarkably compared with the conventional floor body comprised with the lightweight section steel of a cross-sectional groove shape. Needless to say, reinforcing bars, mesh bars, etc. may be arranged on the synthetic slab deck plate. Concrete also includes mortar.

In the present invention, each of the wall bodies includes a lower floor wall panel, a steel boundary beam disposed along the upper edge of the lower floor wall panel, and an upper wall standing on the boundary beam. A floor panel is provided, and a partition panel is erected on the deck plate. The lower floor wall panel, the upper floor wall panel, and the partition panel are all configured by combining a lower frame made of lightweight steel, an upper frame, and a vertical frame with each other. frame is embedded in the concrete, the deck plate to the boundary beams that are supported.

  Such a steel house is a multi-story (two-story, three-story, four-story, etc.) steel house that uses wall panels produced in advance at the factory. Since the deck plate is supported by the boundary beam interposed between the floor wall panel, it is not necessary to perform special processing for supporting the deck plate on the wall panel. In addition, the load acting on the upper floor wall panel and the upper floor body is transmitted to the lower floor wall panel via the boundary beam. In other words, since the load acting on the upper floor wall panel and the upper floor body is dispersed and acts on the lower floor wall panel, local deformation or the like may occur in the lower floor wall panel. Absent.

Invention of Claim 2 is the steel house of Claim 1, Comprising: The said boundary beam is comprised by H-section steel, The wall panel of the said lower floor is formed in the lower surface of the lower flange of the said H-section steel. The lower frame of the upper floor wall panel is fixed to the upper surface of the upper flange of the H-shaped steel.
The invention of claim 3 is a steel house according to claim 2, wherein the H-shaped steel, and the bracket is provided along the longitudinal direction, the deck plate mounting on the bracket It is characterized by being placed

  According to such a steel house, since the boundary beam is made of H-shaped steel, its manufacturing cost is very low.

A fourth aspect of the present invention is the steel house according to the third aspect , wherein the bracket is attached to the H-shaped steel web.

  According to such a steel house, even after an upper floor wall panel is erected on the upper surface of the boundary beam, a deck plate can be laid between opposing wall bodies. That is, this steel house has a high degree of freedom in its assembly process. Another advantage of attaching the bracket to the H-shaped steel web is that the H-shaped steel web functions as a side frame when placing concrete on the deck plate. Simplification is also possible.

A fifth aspect of the present invention is the steel house according to the first aspect , wherein the deck plate is sandwiched between an upper surface of the boundary beam and a lower surface of the wall panel on the upper floor.

  Such a steel house eliminates the need for brackets to support the deck plate, making it possible to simplify and speed up the construction work of the floor, and thus simplify the construction work of the entire steel house. It becomes possible to speed up and reduce the manufacturing cost.

The invention of claim 6 is a steel house according to any one of claims 1 to 5, wherein the lower story wall panels are in the flange of the buried H-beam on top of the basic stand It is provided.

  According to such a steel house, the construction efficiency is remarkably improved as compared with a conventional steel house in which a wall panel on the lower floor is installed using anchor bolts embedded in the foundation. That is, in the conventional steel house, the position of the anchor bolts embedded in the fresh concrete may shift during curing, and in this case, the positioning of the wall panel cannot be performed, which may hinder the installation work. However, in the steel house according to the present invention in which the H-section steel is embedded in the upper part of the foundation, the position of the H-section steel is difficult to shift, and thus the installation work of the wall panel becomes much easier.

Invention of Claim 7 is a steel house as described in any one of Claim 1 thru | or 6 , Comprising: The roof boundary beam is arrange | positioned between the upper end edge of each said wall body, and a roof. It is characterized by.

  According to such a steel house, the weight of the roof and the load acting on the roof are transmitted to each wall body through the roof boundary beam. That is, since the load from the roof is dispersed and acts on each wall body, local deformation or the like does not occur in each wall body. In addition, this roof boundary beam can be applied not only to a multi-storey steel house but also to a one-story steel house.

  According to the steel house according to the present invention, the construction work can be simplified and speeded up, and the production cost can be reduced.

  Next, an assembly procedure of the steel house according to the present embodiment configured as described above will be described with reference to FIGS. 1 and 6.

  In order to assemble the steel house, first, a formwork for constructing the foundation B is installed, and after the H-section steel B1 is installed at a position above the foundation B, the web B13 of the H-section steel B1 is abbreviated. Concrete is cast to the center (see FIG. 6), and when the concrete reaches a predetermined strength, a plurality of lower floor wall panels 11 manufactured in advance at the factory are built on the flange B11 of the H-section steel B1. It fixes on the flange B11 of H-section steel B1 using a volt | bolt and a nut, Furthermore, adjacent lower wall panel 11 is mutually joined using a screw | thread etc. (refer Fig.1 (a)). Similarly, the partition panel 41 is erected and fixed on the foundation B. In addition, although illustration is abbreviate | omitted, the bolt hole through which the volt | bolt for fixing the wall panel 11 of a lower floor is penetrated is drilled in the upper flange B11 (refer FIG. 6) of H-section steel B1. Next, after placing the boundary beam 12 along the upper edge (upper frame) of the wall panel 11 on the lower floor, the boundary beam 12 is fixed to the upper edge of the wall panel 11 on the lower floor using bolts and nuts. Furthermore, a plurality of deck plates 21 are installed between the opposing boundary beams 12 and 12 (see FIG. 1A). Subsequently, a plurality of upper floor wall panels 13 manufactured in advance at the factory are built on the boundary beam 12, and adjacent wall panels 13 are joined to each other using screws or the like, and bolts and nuts are used. Then, each wall panel 13 is fixed to the boundary beam 12 (see FIG. 1B), and then a roof Y is constructed on the wall panel 13 on the upper floor (see FIG. 1C). It should be noted that concrete is cast up to the upper flange B11 of the H-section steel B1 at an appropriate stage after the lower-floor wall panel 11 is erected and fixed to the H-section steel B1 (indicated by reference symbol B 'in FIG. 6). Site). That is, until the lower floor wall panel 11 is erected, the H-section steel B1 is embedded in the foundation B up to the approximate center of the lower flange B12 and the web B13, and the lower floor wall panel 11 is fixed upright. After that, it is buried up to the upper flange B11.

Here, the construction method of the floor body F2 on the upper floor will be described in more detail with reference to FIG. 3 and FIG.
In order to construct the floor body F2 on the upper floor, first, a plurality of deck plates 21 are installed between the brackets 12d and 12d of the opposing boundary beams 12 and 12 without any gap, and both ends in the longitudinal direction thereof are screws or bolts and nuts Is used to fix the bracket 12d (see FIG. 3A). Next, the reinforcing bars 22 are disposed between the ribs 21a and 21a of the deck plate 21 while ensuring an appropriate cover, and the mesh bars 23 are also disposed above the deck plate 21 while also ensuring an appropriate cover (see FIG. 3 (b)). Thereafter, the concrete 24 is placed on the deck plate 21 by a predetermined thickness (see FIGS. 3A and 3B). As shown in FIG. 4, the partition panel 51 constituting the upper floor partition M <b> 2 is erected on the rib 21 a of the deck plate 21 before placing the concrete 24. That is, the lower end portion (lower frame) of the partition panel 51 is embedded in the concrete 24 (see FIG. 3). The concrete 24 may be placed on the deck plate 21 at an appropriate stage, for example, after the roof Y (see FIG. 1C) is constructed.

  As described above, according to the steel house according to the present embodiment, since the types of members constituting the upper floor body F2 are greatly reduced, the construction work of the upper floor body F2 can be simplified and quickly performed. As a result, the construction work of the entire steel house can be simplified and speeded up, and the production cost can be reduced. In other words, in the conventional steel house floor, it was necessary to join a wide variety of members such as edge joists, side joists, floor joists, anti-rollers, wall supports, etc. using a huge number of screws, etc. In the floor F2 on the upper floor of the steel house according to the present embodiment using the plate 21, it is only necessary to place the deck plate 21 and place concrete, so that a complicated work like a conventional floor is unnecessary. It becomes. In addition, in the conventional steel house, floor joists are required to construct the floor body, but in the steel house according to the present embodiment, the floor joists are unnecessary, and therefore the construction work of the floor body should be simplified. Can do.

  Furthermore, since the concrete floor 24 is placed on the deck plate 21 (see FIGS. 3 (a) and 3 (b)), the floor F2 on the upper floor is a lightweight steel having a cross-sectional groove shape. Compared to the conventional floor constructed, it is significantly improved.

  Moreover, since it was set as the structure which supports the deck plate 21 with the boundary beam 12 interposed between the wall panel 11 of a lower floor, and the wall panel 13 of an upper floor (refer FIG. 3 (a), (b)), It is not necessary to perform special processing for supporting the deck plate 21 on the wall panels 11 and 13. Further, the load acting on the upper floor wall panel 13 and the upper floor body F2 is transmitted to the lower floor wall panel 11 via the boundary beam 12. That is, since the load acting on the upper floor wall panel 13 and the upper floor body F2 is dispersed and acts on the lower floor wall panel 11, local deformation or the like occurs in the lower floor wall panel 11. It does not occur. In particular, in the present embodiment, the boundary beam 12 is made of H-shaped steel having a high bending rigidity, so even a load that acts locally on the upper floor wall panel 13 or the like is distributed almost evenly. It will act on the wall panel 11 of.

  Moreover, since the boundary beam 12 is formed of H-shaped steel (see FIGS. 3A and 3B), the material cost is very low. Further, since the web 12a of the boundary beam 12 functions as a side frame when the concrete 24 is placed on the deck plate 21, the work can be simplified.

  Moreover, since it was set as the structure which embeds H-section steel B1 in the upper part of the foundation B, and installs the wall panel 11 of a lower floor using this H-section steel B1 (refer FIG. 6), the anchor bolt embed | buried in the foundation Compared with the conventional steel house where the lower-floor wall panels are installed using the construction, the construction efficiency is remarkably improved. That is, in the conventional steel house, the position of the anchor bolts embedded in the fresh concrete may shift during curing, and in this case, the positioning of the wall panel cannot be performed, which may hinder the installation work. However, in the steel house according to the present invention in which the H-section steel B1 is embedded in the upper part of the foundation B, the position of the H-section steel B1 is difficult to shift, so that the installation work of the wall panel 11 on the lower floor becomes much easier. .

  Moreover, in this embodiment, although the bracket 12d which consists of angle steel was provided in the web 12a of H-section steel (boundary beam 12), the structure which mounts the deck plate 21 on this bracket 12d was illustrated (FIG. 3 (a). In addition, as shown in FIG. 7A, a bracket 12e made of a flat bar is provided on the lower flange 12c of the H-shaped steel, and the deck plate 21 is mounted on the bracket 12e. It may be configured to be placed. The bracket 12e may be formed integrally with the H-section steel (boundary beam 12), or may be formed separately from the H-section steel (boundary beam 12). When the bracket 12e is separated from the H-shaped steel (boundary beam 12), it may be joined to the side edge of the flange 12b of the H-shaped steel (boundary beam 12) by welding or the like. As shown in FIG. 7 (b), the bracket 12e made of a flat bar may be provided on the upper flange 12b of the H-shaped steel, and the deck plate 21 may be placed on the bracket 12e.

In the present embodiment, the deck plate 21 is supported by a bracket 12d (see FIGS. 3A and 3B) or a bracket 12e (see FIGS. 7A and 7B) provided on the boundary beam 12. However, the present invention is not limited to this. For example, as shown in FIG. 8, the deck plate 21 may be supported by the cross beam 14 provided at the upper end portion of the wall panel 11 on the lower floor. . The cross beam 14 is a combination of two or lightweight shape steel, these lightweight shape steel are joined together by screws (not shown) or the like. The lower floor wall panel 11 and the upper floor wall panel 13 are directly joined.

  Even in such a configuration, as in the steel house according to the above-described embodiment, since the types of members constituting the upper floor body F2 are significantly reduced, the construction work of the upper floor body F2 is performed. Therefore, it is possible to simplify and speed up the construction work of the entire steel house, and to reduce the manufacturing cost.

  Moreover, as shown in FIG. 9, the side edge part of the deck plate 21 may be clamped by the upper surface of the boundary beam 12, and the lower surface of the wall panel 13 of an upper floor. That is, the bracket 12d (see FIGS. 3A and 3B) and the like may be omitted, and the side end portion of the deck plate 21 may be placed directly on the upper surface of the boundary beam 12. The deck plate 21 is fixed to the boundary beam 12 using bolts and nuts (not shown) together with the wall panel 13 erected on the upper surface thereof.

  Such a configuration eliminates the need for the bracket 12d and the like for supporting the deck plate 21, so that it is possible to simplify and speed up the construction work of the upper floor F2, and thus the entire steel house. It is possible to simplify and speed up construction work and to reduce production costs.

Moreover, although it is not embodiment of this invention, it replaces with the deck plate 21 and you may construct | assemble the floor body F2 of an upper floor using the concrete panel made from a precast shown in FIG.5 (d).

  As shown in FIG. 10, the concrete panel (the member denoted by reference numeral 25 in FIG. 10) is similar to the deck plate shown in FIG. Placed on. Moreover, the concrete panel 25 has a plurality of hollow holes 25a, and the weight thereof is reduced. Furthermore, since the prestress is introduced into the concrete panel 25 by the plurality of PC steel wires 25b, the proof stress is very high. A mortar 26 is placed on the top surface of the concrete panel 25.

  Even in such a configuration, as in the steel house according to the above-described embodiment, since the types of members constituting the upper floor body F2 are significantly reduced, the construction work of the upper floor body F2 is performed. Therefore, it is possible to simplify and speed up the construction work of the entire steel house, and to reduce the manufacturing cost.
