Description

  The present invention relates to a prefabricated deck plate panel used for a steel frame floor or a concrete slab formwork.

  2. Description of the Related Art Conventionally, when a concrete slab is provided on a reinforced concrete structure or a steel frame floor, a deck plate is used as a temporary floor before concrete construction and as a formwork for casting concrete. Each deck plate has a plate-like shape in plan view, and the length (width w) of the side (short side) supported by the beam in the beam direction is usually 300 to 600 mm, and between the beams (span) As for the length (length 1) of the side (long side) parallel to the beam in the direction, a standard of 1 to 6 m is usually distributed.

  In order to improve the ability to handle vertical loads, deck plates are generally reinforced with a cut surface in the short side direction that is uneven (corrugated), one with a flat surface on one side and a rib on the other side. There is a lightweight thin steel plate. Since the short side (width w) has an uneven cross section, the deck plate can be prevented from being deformed by bending in the long side (length l) direction. For this reason, when using as a temporary floor, the installation of the supporting work for supporting the dead weight and load capacity which should be supported in the concrete placement can be omitted. Moreover, it remains as a part of the reinforced concrete slab as a discarded mold, and contributes to the improvement of the structural strength of the slab itself.

  The deck plates are directly mounted on the flanges of the beams one by one and then fixed by welding or the like. At this time, the long sides of the adjacent deck plates are fitted to each other to form an integral plate surface. Here, since the thickness of the deck plate is considerably thin at 1 mm to 2 mm in order to reduce the weight, if the deck plate is fixed to the beam by fastening with bolts and nuts, shear failure may occur at the end of the deck plate. There is. For this reason, the method of fixing the deck plate to the beam is performed by nailing or the like in the form of the beam in the reinforced concrete structure, and is fixed by welding in the steel structure. In other words, conventionally, welding on the construction site has been required for fixing the deck plate to the steel beam.

  By the way, when constructing floor slabs using deck plates in an industrialized house with parts prefabricated, multiple long sides of multiple deck plates are pre-fitted together in a factory etc. from the viewpoint of simplifying construction site work. Thus, it is conceivable to transport and carry the composite deck plate formed into an integral plate surface to the construction site. In this way, the composite deck plate in which a plurality of deck plates are connected to each other rotates around the joint portion where the long sides of each deck plate are fitted together, so that the entire deck plate surface is easily deformed by bending. It was necessary to limit the length (width W) in the short side direction of the composite deck plate. That is, even when a composite deck plate is used in a factory or the like in advance using a conventional deck plate, the composite width W cannot be arbitrarily set. ), The variation of the size (width W × length L) of the composite deck plate according to various sizes could not be set.

  Also, when using a deck plate as a composite deck plate, we want to avoid welding work at the construction site as much as possible from the viewpoint of ensuring quality. This is because welding work at the construction site largely depends on the craftsman's ability to perform the work, and if the deck plate is welded to the steel beam as it is at the work site, the strength of the base material of the beam may be reduced, etc. This is because variations occur.

  In this regard, for example, in Patent Document 1, a hole is provided in each of the flanges of the H-shaped steel beam 10 and the deck receiver 12 for receiving the deck plate 14 at the connection portion of the beam members 10, 10. The deck receiver 12 is securely fixed to the beam 10 by inserting the bolts 20 through the holes through the connecting plates 16 and 18 that connect the 10 to each other and tightened together with a nut, and the deck receiver extends from the beam 10. The beam structure which mounts and fixes the deck plate 14 to the front-end | tip part 12a of 12 is disclosed. The deck receiver 12 is not provided over the entire length of the beam member 10, but fixes the deck plate 14 with the deck receiver 12 interposed only at the connection point between the beam members 10 and 10.

Japanese Patent Laid-Open No. 10-280601

  However, in the method disclosed in Patent Document 1, the deck plate 14 and the deck receiver 12 are fixed by an arbitrary method such as welding or bolting, and it still has a heavy work load on the construction site. It is done.

  Therefore, the present invention has been made in view of the above-mentioned problems, and corresponds to variations according to the size of the grid of the beam frame designed to be standardized such as industrialized houses, and is standardized and manufactured with an arbitrary size. However, it is an object to provide a prefabricated deck plate panel and a floor structure using the same that are not easily deformed when transported to a construction site, when transported to the site, when installed on a beam of a frame, or after installation. . It is another object of the present invention to provide a deck plate panel and a floor structure using the same that can be easily fixed to a beam with less burden on site work.

  Unlike conventional deck plate (single unit) and deck plate (composite) in which multiple deck plates are connected, it is standardized and manufactured with any dimensions in both vertical and horizontal directions. A prefabricated deck plate that can be easily installed on a building frame is referred to as a “deck plate panel” as described above.

To solve the above problems, the deck plate panels of the present invention comprises a rectangular deck plate portion, a connecting member for fixing the deck plate portion to the beam of the skeleton of a building, the said connecting member, It is a shape obtained by bending a plate material, and has at least one horizontal portion and at least one bent portion which is a bent portion. In the horizontal portion, the plate material is substantially continuous with the short side of the deck plate portion. A plurality of bolt through holes, which are holes for inserting bolts, are drilled in the horizontal portion or the bent portion, and the plurality of bolt through holes have a design module dimension of the building. On the basis of this, it is formed so as to coincide with a plurality of beam holes formed at equal intervals with respect to the beam . Here, the deck plate portion is constituted by a single deck plate using a single deck plate or a composite deck plate in which a plurality of deck plates are connected and integrated.

  Here, the fixing of the connecting member means that the connecting member is previously integrated around the outer periphery of the deck plate by welding or the like in a factory or the like. Is also possible. The phrase “fixed substantially continuously” includes not only the case where the connection member is provided on the entire side along one side of the deck plate portion, but also the case where the connection member is provided only on the main part of the entire side. Here, the main part means an effective part for suppressing in-plane deformation of the deck plate. For example, the connecting member is continuously fixed to the short side central part where the burden of bending stress is large among the short peripheral edges of the deck plate part, and the short side corner part of the deck plate part may be omitted. In this case, the installation range of the connection member may be appropriately determined according to the value of the bending moment. Alternatively, a short connecting member may be continuously fixed so as to connect the joints of adjacent deck plates of the composite deck plate.

  According to the above configuration, by fixing the connection member on the short side of the deck plate portion to the beam, the connection member functions as a reinforcing material for deformation in the panel surface, and rigidity against bending stress generated on the short side of the deck plate portion. And can prevent the bending due to the bending stress on the short side of the deck plate portion and improve the surface rigidity of the entire deck plate panel. Further, since the short side direction of the deck plate portion is reinforced, the size of the deck plate panel (which means a combination of the short side (width W) and the long side (length L)) can be arbitrarily set. it can. In addition, it is possible to prevent deformation of the deck plate itself when it is transported to the construction site, when it is carried on the site, when the frame is installed on the beam, or after installation, thereby reducing the work load on the site.

  Further, when the connection member is fixed to only the main part, the amount of the connection member to be fixed is reduced, so that the deck plate panel can be set to an arbitrary size while reducing the weight of the deck plate panel. .

  In addition, the connecting member of the deck plate panel according to the present invention has a shape obtained by bending a horizontal plate in a cross-sectional view, and has at least one horizontal portion and at least one bent portion which is a bent portion. The horizontal plane portion may be fixed to the deck plate portion. For example, the connecting member has a cross-sectional shape processed into an L shape, a Z shape, a T shape, or the like. Further, it is preferable to use a long member that is substantially continuous along the side of the panel as the connecting member.

  As described above, by providing the bent portion of the connecting member, the strength against deformation due to bending of the connecting member itself is increased. In addition, by fixing this connecting member substantially continuously to the outer periphery of the deck plate part of the deck plate panel, the in-plane strength of the entire deck plate panel is further increased, and it is deformed during transportation, on-site delivery or installation. Less likely to do.

In the deck plate panel according to the present invention, a bolt through hole that is a hole for inserting a bolt may be formed in the horizontal portion or the bent portion of the connecting member.
For example, in the horizontal part of the connecting member, a bolt through hole which is a hole for inserting a bolt penetrating the hole provided in the beam is provided and drilled so as to penetrate the deck plate part and the horizontal part of the connecting member. To be. The bolt through holes are formed so as to coincide with the beam holes of the frame beam (which is formed at equal intervals based on the design module dimensions) which is a building frame.
In this case, the deck plate panel is fixed to the beam only by fastening the connecting member and the beam with bolts and nuts. Therefore, the burden of field work is small and the deck plate panel can be easily fixed to the beam.

  For example, the bent portion of the connecting member is formed vertically and a bolt through hole through which the bolt is inserted is formed, and the vertical surface portions of the adjacent deck plate panels straddling the beam may be fastened with bolts and nuts to be connected. . By doing so, it is possible to obtain a floor structure in which the deck plate panels are integrated and securely fixed.

For example, the connecting member has three surfaces: a cross-sectional view, a first horizontal portion, a vertical portion, and a second horizontal portion, and the vertical portion is connected to the first horizontal portion and the second horizontal portion. The first horizontal portion may be fixed to the deck plate portion. By doing in this way, a predetermined level | step difference can be provided in a deck plate part with respect to a beam. That is, when the second horizontal portion of the connection member is overlapped and fixed on the upper flange surface of the beam, the deck plate portion is fixed to the first horizontal portion with a step corresponding to the length of the vertical portion of the connection member. The As a result, design changes such as increasing the thickness of the concrete slab and increasing the strength without changing the floor height (column length, height between upper and lower layers) of the frame are possible, and design flexibility is increased. Increase. In the deck plate panel according to the present invention, the connection member may be fixed to the long side of the deck plate portion. By doing so, it becomes possible to fix the connecting member on the long side of the deck plate part to the beam, not only the rigidity against the bending stress generated on the short side of the deck plate part, but also concrete during earthquakes, etc. It is also possible to increase the rigidity against shear stress generated in the slab. Here, being fixed to the long side is not only the case where a long connecting member is provided continuously over the entire side of the deck plate part, but may also be a continuous fixing of a short connecting member, The short connection member may be provided as appropriate only at both ends and the center of the long side of the deck plate portion. In the deck plate panel according to the present invention, the size (combination of the width W and the length L) may be a size based on a design module dimension that is a reference dimension used for building design. By doing this, standardized as multiple parts using the design module dimensions of industrialized houses, deck plate panels of the size required for each house according to the frame structure designed as an individual industrialized house (house) The size and quantity can be picked up, manufactured, transported to the site, and installed. Here, the size based on the design module dimension includes an integral multiple of a unit dimension or a fraction of an integer. Further, in the deck plate panel according to the present invention, the deck plate portion includes an enclosing portion that is crushed at an end portion of a convex-concave mountain portion on a short side and is closed in a side view. The portion is formed obliquely downward from the upper surface side to the lower surface end portion side of the deck plate portion, and the plurality of bolt through holes are formed in the bent portion of the connection member.

  Next, the floor structure in the present invention is a floor structure using the deck plate panel in the present invention described above, and a horizontal portion or a bent portion in which a bolt through hole is drilled is fixed to a beam, and the bolt through hole and The deck plate panel and the beam are fixed by inserting a bolt through the beam hole formed in the beam and fastening with the bolt and the nut. For this reason, if it is the floor structure in this invention, it is possible to fix a deck plate panel to a beam by the fastening by a volt | bolt and a nut, without carrying out a shear failure.

Further, the floor structure in the present invention has a square deck plate part and a connection member for fixing the deck plate part to a beam of a building frame, and the connection member has a shape obtained by bending a plate material. A plurality of bolts that have at least one horizontal part and at least one bent part that is a bent part, and that are holes for inserting bolts into the horizontal part or the bent part. A floor structure using a deck plate panel with holes formed therein, wherein the beam has a shape in which two upper and lower flanges are connected by a web, and the connection member is fixed to the flange or the web. The lower surface of the deck plate portion is lower than the upper surface of the upper flange of the beam.

Further, in the floor structure according to the present invention, the connecting member is fixed to all the outer peripheral sides of the deck plate portion, and one deck plate panel is arranged in an area surrounded by the four beams. Then, each of the connecting members may be fixed to the surrounding beam to constitute a floor in the region. By doing so, it is not necessary to arrange and connect a plurality of deck plate panels in an area surrounded by beams, and the number of processes at the building site can be reduced. In the floor structure in the present invention, a plurality of deck plate panels may be arranged in an area surrounded by beams to constitute a floor in the area. By doing in this way, even if a narrow site such as an urban area where a deck plate panel of a certain size or more cannot be carried is a construction site, a floor structure can be formed by the deck plate panel in the present invention. It becomes possible.

  According to the present invention, it is possible to fix to a beam by fastening with bolts and nuts without shear fracture, and even when manufactured with any size, it is deformed during transportation, at site delivery, installation or after installation It is possible to provide a deck plate panel and a floor structure using the same.

  Next, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 is a perspective view of a deck plate panel 100 according to the first embodiment of the present invention. FIG. 2 is a diagram illustrating an example of a column beam frame in a steel framed ramen structure building. The deck plate panel according to the present embodiment is arranged in a region surrounded by the beam 200 in a column-column structure of a shaft set as shown in FIG. 2, and forms a floor structure. FIG. 3 is a plan view of a floor structure formed by arranging the deck plate panel 100 according to the present embodiment on the shaft set shown in FIG. FIG. 4 is an enlarged plan view of a portion indicated by A in FIG. 5 is a cross-sectional view showing a cross section taken along line XX of FIG.

As shown in FIG. 1, the deck plate panel 100 according to the present embodiment includes a square deck plate portion 110 and a connecting member 120 for fixing to the beam 200. The connecting member 120 is disposed on the short side of the deck plate portion 110, and the deck plate portion 110 and the connecting member 120 are fixed on the short side. As a method for fixing, a method is used in which the material of the deck plate 110a constituting the deck plate portion 110 is not sheared. For example, the deck plate part 110 and the connection member 120 may be fixed by welding at a factory or the like.

  For example, as shown in FIG. 1, the length of the short side and the long side of the deck plate unit 110 is determined according to the size of the region surrounded by the beams in a predetermined layer of the steel frame.

  Further, the deck plate portion 110 has an uneven cross-sectional shape cut in the direction of the short side (the width W of the deck plate panel) installed on the beam on the beam row side of the grid. Thus, by making the cross section of the deck plate portion 110 uneven, it is possible to suppress deformation due to bending of the long side (the length L of the deck plate panel) among the sides of the deck plate portion 110. Therefore, even if it is made of a thinner steel material, the in-plane strength of the deck plate portion 110 can be improved, and the weight can be reduced.

  Further, the uneven shape of the deck plate portion 110 is, for example, a corrugated shape having a crest portion 111 and a trough portion 112, and the adjacent crest portions 111 are brought into contact with each other so that the trough portions 112 protrude from the lower rib. It can be processed and its upper surface can be made flat. When the deck plate portion 110 has a wave shape, the connection member 120 is preferably fixed on the lower surface of the valley portion 112.

  The deck plate portion 110 may be constituted by a single steel plate deck plate 110a (the deck plate portion 110 constituted by a single deck plate is referred to as a “single deck plate 110S”), but is shown in FIG. As shown, a plurality of well-known deck plates 110a may be connected and integrated to form a composite (the deck plate portion 110 including a plurality of deck plates is referred to as a “composite deck plate 110M”). . As the deck plate 110a, a commercially available deck plate with standardized dimensions of width w and length l can be used. In addition, as a commercially available deck plate, for example, there are those having a width w of about 300 to 600 mm and a length l of 1000 to 6000 mm, and these may be selected and used. A commercially available deck plate has a fitting portion 115 as shown in FIG. 7, for example, in order to connect the two deck plates 110a. Therefore, as shown in FIG. 6, a plurality of commercially available deck plates are connected using this fitting portion 115 to form a composite deck plate 110M, thereby forming the deck plate portion 110 of the deck plate panel 100. Good. Further, as shown in FIG. 6, an adjustment deck plate 110b may be used in order to match the size of the deck plate panel 100 to the size of the area to be arranged.

  Further, as shown in FIGS. 1 and 5, the deck plate 110 a forming the deck plate portion 110 is a closed end-closed portion in which a convex-concave (wave) -shaped crest portion 111 is crushed at an end of a short side, and is viewed from the side. An end closed deck plate having a portion 113 may be used. By providing the enclosed part 113 in the deck plate part 110, when concrete flowing into the upper part flows into the upper part, the concrete enters the part of the end part of the unevenness (wave) shape and falls to the lower floor. It becomes possible to prevent.

  As shown in FIG. 5, the connecting member 120 has a cross-sectional view and a bent shape, and has an L shape having two pieces of a horizontal portion 121 and a vertical portion 122. The deck plate part 110 is fixed to the horizontal part 121. The vertical portion 122 rises upward around the end portion of the deck plate portion 110. Hereinafter, the connection member 120 having this shape will be referred to as an L-type connection member 120.

  As shown in FIG. 5, in order to fix the deck plate panel 100 to the beam 200, the deck plate portion 110 is provided with a bolt through hole 114 that is a hole through which a bolt is inserted. Also in 121, a bolt through hole 123, which is a hole for inserting a bolt, is formed. That is, as shown in FIG. 5, a bolt through hole is formed in the deck plate panel 100 so as to penetrate the end portion of the deck plate portion 110 and the horizontal portion 121 to which the connecting member 120 is fixed. ing.

  When the uneven deck plate is used, the bolt through hole 114 is preferably formed in the valley portion 112. Further, in the case of drilling into the mountain portion 111, the mountain portion 111 is preferably crushed at the position where the bolt through hole 114 is drilled. For example, when the enclosed deck plate 110a is used as the deck plate portion 110, the mountain portion 111 is crushed as shown by the dotted line in FIG. Is possible.

  Here, as shown in FIG. 2, a plurality of beam holes 201 are formed in the frame beam 200 at equal intervals. For example, as the beam 200, an H-shaped steel having a shape in which two upper and lower flanges 202 and 203 as shown in FIG. 5 are connected by a web 204 is used, and a beam hole 201 is formed in the flange 202.

  Usually, the standard dimension (module) is used for the design of a building, but the beam hole 201 is used for joining a column or the like to the beam 200, and is a design module adopted in an industrialized house. It is provided at equal intervals from the reference point in units of dimensions. For example, as shown in FIGS. 3 and 4, a pair of beam holes 201 are provided at a predetermined interval I across the reference point (midpoint P).

  Therefore, in order to correspond to the beam hole 201, the bolt through hole 114 of the deck plate portion 110 and the bolt through hole 123 of the connecting member 120 are also measured in units of the design module dimensions adopted in the industrialized house as in the case of the beam 200 of the frame. Are provided at equal intervals from the reference point. At this time, a pair of bolt through holes 114 are also provided at a predetermined interval I across the reference point (midpoint P) in the deck plate portion 110 as well as the beam hole 201. That is, the beam hole 201, the bolt through hole 114 of the deck plate portion 110, and the bolt through hole 123 of the connecting member 120 are formed at equal intervals using a common design module dimension. The reference dimension with the design module dimension as a unit is set to an integral multiple of, for example, a minimum value of 305 mm.

  When the deck plate panel 100 is fixed to the beam 200, the end portion of the deck plate portion 110 formed of a thin steel plate deck plate (for example, a plate thickness of 1 mm to 2 mm) is directly fastened to the beam with bolts and nuts. Without fixing, bolts and nuts are connected via a long and thick connecting member 120 (for example, a plate thickness of 3.2 mm) welded along the end of the deck plate unit 110 in advance at a factory or the like. It is concluded with. For example, as shown in FIG. 5, the deck plate panel 100 is placed on the upper surface of the flange 202 of the beam 200 so that the horizontal portion 121, which is a portion where the deck plate portion 110 and the connection member 120 are fixed, comes to the upper portion of the beam 200. And the position of the bolt through hole 123 of the connecting member is aligned with the beam hole 201. Next, the bolt 300 is inserted into the bolt 300 from the upper side of the deck plate panel 100 toward the lower side of the flange 202 of the beam 200 and tightened with the nut 400.

  The plate thickness of the connecting member 120 is set so as not to be sheared by fastening bolts and nuts. By doing in this way, the deck plate part 110 is not sheared and destroyed. It is also possible to prevent the beam 200 from being damaged by field welding.

  Further, as shown in FIG. 8, the horizontal portion 121 of the deck plate panel 100 is disposed on the upper portion of the flange 203 below the beam 200, and the deck plate panel 100 is fastened to the lower flange 203 with bolts and nuts. May be fixed. In addition, in FIG. 8, when it is the beam 200 inside a building, the connection member 120 installed in the left side centering | focusing on the web 204 of the beam 200 is required, but the graphical representation in that case is omitted ( The same applies to FIGS. 10 and 11 below.) In FIG. 8, a solid line indicates an enclosed deck plate 110 a whose ends are crushed, and a two-dot chain line indicates a normal deck plate 110 a whose ends are not crushed (hereinafter referred to as “deck plate”). The same applies to FIG. 10, FIG. 11, and FIG.

  Note that the cross-sectional shape of the beam 200 is not limited to the H shape described above, but is also a C channel type, a box shape, or the like. When a C-channel type, a box type, or the like is used as the beam 200, similarly to the above, a beam hole is provided in the beam 200, and a bolt through hole is formed in the horizontal portion 110 or the vertical portion 120 of the connecting member 110. The bolts may be inserted through the bolt through holes and tightened with nuts, and the deck plate panel 100 may be fixed to the beam 200.

  Further, as an embodiment different from the above, a second horizontal portion is present as a portion where the deck plate portion 110 is not fixed to the horizontal portion 121 of the connecting member 120, and the bolt through hole is formed in the second horizontal portion. You may make it wear. That is, the bolt through hole 123 may be formed only in the connection member 120. In this case, it is not necessary to make a through hole in the deck plate portion 110, and the manufacturing process of the deck plate panel 100 can be simplified.

(Reinforcing effect by connecting member 120)
As described above, since the conventional deck plate is a thin steel plate, it is easily deformed. On the other hand, in the deck plate panel 100 according to the present embodiment, the connection member 120 is fixed substantially continuously to the entire side of at least one side of the short side of the deck plate portion 110 to which the connection member 120 is fixed. Even if the connecting member 120 serves as a reinforcing member and the thickness of the deck plate portion 110 is a thin plate similar to that of a normal deck plate, the deck plate panel 110 according to the present embodiment is bent. In-plane deformation is suppressed, and a greater strength is obtained. Therefore, in the case of the deck plate panel according to the present embodiment, the dimensions in both the width W and length L directions can be increased, and a panel having an arbitrary size can be manufactured. For this reason, in the case of the deck plate panel 100 according to the present embodiment, even if the size is adjusted to the size of the area surrounded by the beam, The inner deformation can be suppressed and the shape can be maintained.

  Further, as described above, the connecting member 120 of the deck plate panel 100 according to the present embodiment is a long steel material extending from one end of one side of the deck plate portion 110 to the entire other end, and has an L-shaped cross-sectional view and a plate thickness. Is thicker than the deck plate portion 110, the connection member itself has a high strength against deformation due to bending or the like. Therefore, the possibility that the deck plate panel 100 provided with such a connection member 120 will be deformed during transportation, on-site delivery, installation, or after installation is further reduced.

  In the above, the connection member 120 is fixed substantially continuously to the entire side in addition to the case where the connection member 120 is provided from one end to the other end of one side of the deck plate portion 110, The case where it is provided only in the principal part connected with the beam 200 among the deck plate parts 110 is also included. Here, the main part refers to a part effective for suppressing in-plane deformation. In this case, since the amount of the connection member 120 to be fixed is reduced, it is possible to prevent the deck plate portion 110 from being sheared while reducing the weight of the deck plate panel 100. For example, the connection member 120 may be continuously fixed to the short side central portion of the outer peripheral short side of the deck plate portion 110 where the bending stress is large, and the short side corner portion of the deck plate portion 110 may be omitted. Good. In this case, the installation range of the connection member may be appropriately determined according to the value of the bending moment. Further, as shown in FIG. 6, the connecting member 120 (indicated by a two-dot chain line) has a short length so as to connect the seam between the adjacent deck plate 110a and 110a or 110b of the composite deck plate 110M constituting the deck plate portion 110. The connecting member 120 may be fixed continuously. The connecting member 120 is provided with bolt through holes 123, and the bolt through holes 123 are formed in the beam holes 201 of a framed beam, which is a building frame (performed at equal intervals based on the design module dimensions). Match.

  Further, the deck plate panel 100 may be configured such that the connecting member 120 is substantially continuously fixed to the long side of the deck plate portion 110 and is substantially continuously fixed to all the outer sides. good. In this way, not only the rigidity against bending stress can be increased, but also the rigidity against shearing stress can be increased.

  Furthermore, as a form to be fixed to the long side, not only when a long connecting member is provided continuously over the entire side of the deck plate part 110, but also a short connecting member 120 may be fixed continuously, The short connection member 120 may be provided as appropriate only at both ends or the center of the long side of the deck plate portion 110. Further, the connecting member 120 is provided with a bolt through-hole 123, and this bolt through-hole 123 is made to coincide with the beam hole 201 of the frame beam which is a building frame.

  Further, if the connection member 120 is fixed to the entire outer periphery of the deck plate part 110, it is more preferable in terms of prevention of in-plane deformation and strength of the single deck plate 110S or the composite deck plate 110M of the deck plate part 110, and it is constituted by a beam of a frame. It can be firmly fixed for each area. In addition, since the gap between the beam 200 (the upper surface of the flange 202) and the deck plate portion 110 of the deck plate panel 100 is stopped by the connecting member 120, it is prevented from falling to the lower floor when slab concrete is poured. it can.

(Connection between two adjacent deck plate panels 100)
As shown in FIG. 5, a bolt through hole 124 may also be formed in the vertical portion 122 of the connecting member 120. When this bolt through hole 124 is used, as shown in FIG. 5, two deck plate panels 100 adjacent to each other across the beam can be fastened and fixed by bolts 310 and nuts 410. That is, by inserting the bolt 310 so as to penetrate both of the bolt through holes 124 in the vertical portion formed in the connecting member 120 of the two adjacent deck plate panels 100, and fastening with the bolt 310 and the nut 410, The two adjacent deck plate panels 100 can be connected. Thereby, it becomes possible to obtain a floor structure in which the deck plate panel 100 is more reliably fixed.

  It should be noted that the interval through which the bolt through hole 124 of the vertical portion 122 is drilled may be the same as the predetermined interval I of the beam hole, or a different interval from a multiple of the predetermined interval I such as skipping one. However, the holes are made to coincide with each other so that a predetermined installation position with respect to the beam is secured. In addition, the bolt through hole 124 drilled in the vertical portion 122 has a pair of two bolt through holes in order to increase the degree of fixation, similarly to the bolt through hole 123 drilled in the horizontal portion 121.

(Floor structure using deck plate panel 100)
A case where the deck plate panel 100 according to the present invention is applied to a steel framed ramen structure building will be described. As shown in FIG. 2, a building having a steel frame ramen structure forms a frame by rigidly joining a beam 200 to a column 600. The portion surrounded by the four pillars 600 is usually called a grid. As shown in FIG. 2, a plurality of beams 200 are laid on the inner side of the grid, and the grid is subdivided. Hereinafter, each of the subdivided portions, that is, the portions surrounded by the four beams 200 will be referred to as a small grid.

  In the floor structure according to the embodiment of the present invention, as shown in FIG. 3, one deck plate panel 100 is arranged on this small grid. As described above, since the deck plate panel 100 according to the present embodiment is reinforced by the connecting member 120, even if the deck plate panel 100 is sized to the size of the small grid, it is transported, carried on site, and installed. Or it does not deform after installation. Therefore, unlike a normal deck plate, with the deck plate panel 100 according to the present embodiment, as shown in FIG. 1, only one deck plate panel 100 can be arranged for each small grid. Therefore, when placing on a small grid, it is not necessary to connect several deck plates necessary for using ordinary deck plates at the construction site. Therefore, by using the deck plate panel 100 according to the present embodiment, it is possible to reduce the number of processes at the construction site.

  As described above, a standard dimension (module) is usually used for building design. For this reason, the dimension of each side of the small grid surrounded by the beam has a dimension based on the reference dimension. Therefore, as a combination of the width (W) and the length (L) of the deck plate panel 100 according to the present embodiment, a plurality of types may be prepared according to a standard based on this reference dimension. For example, as the standard of the deck plate panel 100, the types shown in Table 1 may be prepared. In this way, by designing a plurality of types of deck plate panels 100 as industrialized products according to standards based on reference dimensions, a panel having a required size can be selected according to the design of individual houses. It becomes possible to manufacture.

  In Table 1, the sizes that are standardized and prepared in advance for building design and factory manufacture are indicated by circles. For example, in Table 1, in the column (L) of 305 mm × 5, circles are written in the row (W) of 305 mm × 5 and the row (W) of 305 mm × 6. L) is 305 mm × 5 = 1525 mm, a deck plate panel with a width (W) of 305 mm × 5 = 1525 mm, a length (L) of 305 mm × 5 = 1525 mm, and a width (W) of 305 mm × 6 = 1830 mm deck plate panel is prepared.

  Note that two or more standard deck plate panels 100 may be arranged (divided arrangement) in one small grid. For example, two deck plate panels 100 having a width (W) of 305 mm × 6 = 1830 mm and a length (L) of 305 mm × 6 = 1830 mm are arranged for a small grid with a beam going to 3660 mm and a beam spacing of 1830 mm. By doing so, it is possible to form a floor structure with the deck plate panel 100 according to the present embodiment even in a construction site where a deck plate panel 100 of a certain size or larger cannot be carried.

  When one deck plate panel 100 is arranged on one small grid, the connection member 120 is preferably fixed to all the outer peripheral sides of the deck plate portion 110. Further, when the plurality of deck plate panels 100 are arranged (divided arrangement) on the small grid, it is preferable that the connecting member 120 is fixed only to the side of the deck plate portion 110 in contact with the beam 200 of the deck plate portion 110. At this time, when the deck plate portion 110 has an uneven (wave) shape, as described above, the short side of the deck plate portion 110, that is, the unevenness (wave) shape, suppresses deformation that is vulnerable to bending. It is preferable that the connection member 120 is fixed to a side in a non-direction (weak axis). Also in each direction of the panel, it is possible to suppress bending deformation due to bending, and it is possible to prevent deformation of the deck plate panel 100 during transportation, on-site delivery, installation, or after installation.

  Further, when a plurality of deck plate panels 100 are arranged (divided arrangement) in one small grid, a fitting portion for connecting to an adjacent deck plate panel 100 on the side where the connecting member 120 is not fixed. 115 may be provided. For example, as the fitting portion 115, a fitting portion 115 as shown in FIG. By doing in this way, it becomes easy to fit together the fitting part 115 of these two deck plate panels 100, and to connect and integrate the edge parts without a gap. Therefore, by providing such a fitting portion 115, it is possible to prevent the concrete poured into the upper portion of the deck plate panel 100 from falling to the lower floor or the like of the deck plate panel.

Thereby, the corner | angular part of the deck plate panel 100 in a grid corner can be reinforced, and it becomes possible to prevent a deformation | transformation.

  On the other hand, when the pillar 600 exists in the corner portion of the deck plate panel 100, the shape of the corner portion of the deck plate panel 100 is matched to the outer shape (column shape) of the pillar 600 as shown in FIG. It is necessary to form a concave shape by notching a part of the corner of 110. FIG. 9 is an enlarged plan view of a portion indicated by B in FIG. In FIG. 9, the horizontal surface portion 121 of the connection member 120 existing on the back side of the deck plate portion 110 is indicated by a dotted line. At this time, in order to make up for the lack of strength in this portion, it is preferable to connect the two connecting members 120 fixed to the two sides using the connecting member 700 shown by a dotted line in FIG. As the connecting member 700, a steel plate as shown in FIG. 9, an L-shaped reinforcing bar, or the like having a shape that matches the outer shape of the column is used. Thereby, even when the corner portion of the deck plate panel 100 has a recessed shape, deformation at the corner portion can be prevented.
