  Patent Document 1 is an invention relating to a “flat roof”, and in a roof structure that requires heat insulation performance, by installing a heat insulation panel directly on the beam, the conventional construction work of the folded plate is omitted, and workability is improved. It was to be able to increase. However, the roof constructed by this type of flat roof cannot be widened because the distance between the beams to which the heat insulation panel is attached is limited due to the strength problem depending on the connection (fitting) method of the heat insulation panel. Furthermore, there was a problem that the fitting part was disengaged during a fire.

  In order to solve such drawbacks, the present invention connects a front panel and a rear panel of adjacent panels in a structure in which a core sandwiched between a front panel and a rear panel is connected by male and female. This is a connection structure of panels connected by tools, and the connection tool provides a connection structure of panels that does not penetrate two adjacent panels.

  According to the connection structure of the panel which concerns on this invention, by connecting the surface material and back surface material of an adjacent panel with a connection tool, (1) Adjacent panels are integrated sequentially and the whole roof surface is one panel. Thus, the strength is improved, the space between the base beams can be made wider than before, the cost is low, the workability is high, and the construction period can be shortened. (2) After connecting the panels, even if a heavy object is placed, the deflection is reduced. For example, even when a construction machine is run, the panel itself is hardly broken or broken. (3) The gap between the male and female fitting portions of adjacent panels is reduced, and airtightness performance, heat insulation performance, and waterproof performance are improved. (4) Since the connecting tool that connects adjacent panels does not penetrate to the back surface of the panel, the deterioration of the airtight performance, the heat insulating performance, and the waterproof performance due to the connecting tool can be prevented, and the deterioration of the panel can be prevented for a long time. (5) Since waterproof performance can be ensured simply by constructing panels, indoor work can be started immediately without being influenced by the weather, and the entire construction period can be shortened. (6) With this connection structure, general panels used for walls can be used for flat roofs. There are such features and effects.

In addition, in the core material 3, lightweight aggregates (perlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, Graphite etc.) can be mixed to improve fire resistance and fire resistance.

  Therefore, an embodiment of the construction sequence of the panel connection structure according to the present invention will be described in detail. First, a panel A as shown in FIGS. 7A to 7C is connected and fixed on a horizontal base α as shown in FIGS. 1 to 3, and shown in FIGS. 8A, 8B, and 9. It is formed as the roof base of the rooftop K. 8A is a plan view showing a state in which a fixture β for fixing the panel A to the base α is applied, and FIG. 8B is a plan view showing a state in which a connector γ for fixing the panels A is applied. FIG. 9 and FIG. 9 are plan views showing a state in which the fixing tool β and the connecting tool γ are installed.

  The panel A is a long one having a working width of about 600 to 1000 mm and a length of about 900 to 3600 mm, and the interval of the base α is appropriately determined according to the length and width of the panel A, A joint portion M between the panels A adjacent to the end face of the end in the longitudinal direction is formed on the base α.

  As shown in FIGS. 2A, 2 </ b> B, and 4 </ b> A, the panel A is connected by connecting the fitting piece 8 of the female connecting portion 5 to the engaging groove 6 of the male connecting portion 4. The panel A is sequentially connected by connecting the engagement piece 7 of the male connection part 4 to the fitting groove 9 of the female connection part 5.

  The panel A is fixed to the base α as shown in FIGS. 1, 2A, 2B, 3A, 3B, 5A, and 5B. A fixing device β such as a screw screw is provided from the lower end 10a to the upper end 10b of the decorative surface 10 of the panel A as shown in FIGS. 7 (a) to 7 (c), from the lower end 10a to the innermost piece 6b. The both ends of the panel A in the joint portion M are fixed to the base α within the range of W1 obtained by subtracting the distance W2 up to.

In FIG. 8 (a), the upper and lower ends and the central portion of the decorative surface 10 at both ends of the panel A at the joint M portion and within the width W1 of the decorative surface 10 are fixed by the fixture β. It is fixed to the base α. Of course, the number of fixing tools β to be placed is arbitrary, but the fixing pitch is preferably, for example, 450 mm or less in terms of strength.

  As shown in FIGS. 3 (a), 3 (b), 4 (b), 5 (b), and 6 (b), the construction of the panel A at the joint portion M is performed between the end portions of the panel A. A joint packing material P1 made of urethane foam is formed to improve the waterproofness and airtightness of the joint part M. Of course, as the joint packing material P1, foamed rubber, polyvinyl chloride, chloroprene, chlorosulfonated polyethylene, ethylene propylene, asphalt impregnated polyurethane, EPM, EPDM, etc. can be used as regular and elastic packing materials. To improve the fire resistance of the joint M, use rock wool felt, ceramic wool, glass wool, asbestos, gypsum board, various inorganic foams, ultra-high density phenol foam, rock wool mixed with graphite, etc. Is.

  The connector γ is a mounting screw for further firmly connecting and fixing the fitting portion G of the connected panel A, and is for connecting the fitting portion G portion between the panels A. This prevents gaps from being formed between the portions G, and improves airtightness performance, heat insulation performance, and waterproof performance. When the thickness H of the panel A is set as shown in FIG. As shown in FIG. 6 (a), when the height of the connector γ is H1, the relationship of H> H1 is established, and as shown in FIG. 7 (c), from the decorative surface 10 of the panel A to the upper edge 8b of the back material 2 Assuming that the thickness is H2, the relationship of H1> H2 is established. This is a dimensional relationship that prevents the connecting tool γ from penetrating through two adjacent panels A as shown in FIG. 6A when the connecting tool γ is driven.

  As shown in FIGS. 1, 6A, and 6B, the connection between the panels A by the connector γ does not reach the base α at the intersection of the joint portion M and the horizontal joint portion Y. The panels A are fixed to each other and are formed so as not to penetrate the back material 2 to prevent deterioration of airtightness, heat insulation and waterproofing, and to prevent deterioration of the panel A over a long period of time. In addition, by simultaneously connecting the surface material 1 and the back surface material 2 of the panel A and the surface material 1 and the back surface material 2 of the adjacent panel A, the four metal plate materials of the panels A by one connector γ. a and the metal plate material b are connected and fixed simultaneously. Of course, even in a portion where the base α does not exist, such as a beam, the connector γ is formed so as not to penetrate through the adjacent panels A.

  More specifically, as shown in FIG. 6A, the connector γ includes the decorative surface 10 of the panel A2, the upper edge 6a of the panel A2, the fixing piece 8a of the panel A1, the upper edge 8b of the panel A1, and the insertion of the panel A2. It is driven in the order of the piece 6c, the male lower edge 2a of the panel A2, and the female lower edge 2b of the panel A1, and finally the tip of the connector γ is present in the core 3 on the back surface of the female lower edge 2b of the panel A2. It will be.

  As shown in FIG. 6A, the connecting position of the connector γ is set at a substantially central portion in the range of W3, where W3 is from the uppermost end of the back material 2 to the tip of the engagement piece 7. . By forming in this way, the gap of the fitting part G between adjacent panels A is reduced, the airtightness performance, heat insulation performance and waterproof performance are improved, and the entire roof is like one panel and the strength is improved. However, the space | interval of the base | substrate (alpha) can be taken widely compared with the past.

  As shown in FIG. 8 (b), the pitch P4 in the longitudinal direction of the panel A of the connector γ is 100 mm to 450 mm (preferably 300 mm or less in terms of strength), but the length of the panel A (of the base α) Formation pitch) X, the working width Z of the panel A, the thickness H of the panel A, the cross-sectional secondary moment that is the cross-sectional performance of the heat insulating panel A, and the cross-section coefficient are determined. Of course, when walking on the roof K where the panel A was constructed, or running a construction machine, or installing the air conditioner or water tank such as an air conditioner on the roof K, and the maintenance work, the panel A Is set so as not to break.

In addition, in order to clarify the placement positions of the fixing tool β and the connecting tool γ, the point / line (printing), the concave / concave / convex form (molding), and the punch marks (fixed pitch) that can visually confirm the placement position ( It is also possible to form a dent) on the panel A.

  Further, by forming the base α on which the panel A is constructed with an inclination, it can be used not only as a flat roof but also as a normal roof or a roof base. Of course, when using as a roof as it is, a structure with waterproof performance is formed by attaching a weatherproof, ultraviolet resistant, waterproof tape or the like to the joint M and the lateral joint Y. .

  The groove space 8c formed in the fitting part G between the panels A shown in FIG. 6A is provided in the fitting part G of the panel A which is a concern when a pressure difference occurs between the indoor side and the indoor side. The pressure applied to the waterproof layer is dispersed in the longitudinal direction in the horizontal joint Y direction of the panel A, and a reliable waterproof layer is formed in the fitting portion G.

  What has been described above is only one embodiment of the panel connection structure according to the present invention, and it can be formed as shown in FIGS. 10 (a) and 10 (b) to FIG.

  10 (a) and 10 (b), a joint tape 11 using aluminum foil is attached to the joint portion M and the horizontal joint portion Y of the flat panel A, and the entire surface of the panel A on the upper surface is adhered. It is covered with a waterproof sheet 12 and improves heat insulation, waterproofness, and airtightness between the ends of adjacent panels A. In addition, when the panel A is constructed on the inclined base α, and the joint portion M and the transverse joint portion Y are constructed with the joint tape 11, it can be used as it is as a roof.

The waterproof sheet 12 is made of asphalt, modified asphalt, synthetic rubber, or a soft polymer material having waterproof properties, such as soft polyvinyl chloride resin, polyolefin resin, vinyl chloride thermoplastic elastomer, polyolefin thermoplastic elastomer, etc. It is formed from a soft thermoplastic synthetic resin. In the case of bonding by heat fusion rolling or the like, a material made of a soft polyvinyl chloride resin is used. In addition, in the panel A used for the connection structure of the panel which concerns on this invention, the asphalt waterproofing method which can be adhere | attached on the panel A whole surface from a viewpoint of wind-resistant pressure strength is more desirable.

  FIGS. 11A and 11B show the panel A in which the end face piece 13 is formed on the end face of the panel A in the longitudinal direction and the workability, waterproofness, and airtightness of the joint portion M are improved.

  FIGS. 12A and 12B are explanatory views showing other connection structures of the panel A, and FIGS. 13A and 13B are cross-sectional views showing the construction state of the panel A shown in FIGS. 12A and 12B. It is.

  FIG. 14 shows that a long metal sheet 14 is formed between the panel A and the base α of the joint portion M of the panel A, thereby improving the waterproofness, airtightness, fireproofing, and fire resistance of the joint portion M. Is. The material of the siding plate 14 is not limited to metal, but can be appropriately determined according to the purpose.

  According to the connection structure of panels according to the present invention, adjacent panels A are sequentially integrated so that the entire roof surface looks like one panel A, the strength is improved, and the distance between the beams serving as the base α is increased. Compared with the conventional method, the cost can be reduced, the workability is high, and the construction period can be shortened. Moreover, since waterproof performance can be ensured only by constructing panel A, indoor work can be started immediately without being influenced by the weather, and it can be effectively utilized for shortening the overall construction period and reducing costs.
