Description

  The present invention efficiently mounts deck materials, wall plates, and the like in the installation work of deck materials arranged in parallel on a floor surface such as a terrace in a building, or wall materials attached to pillar materials, etc. In addition, the present invention relates to an improvement in the connection structure between a plate material and a metal frame that can be accurately finished.

  Conventionally, in a construction where deck materials are arranged and fixed on a floor surface such as a terrace, for example, as shown in FIG. 19, a deck material A made of synthetic resin is arranged on a metal joist material B such as aluminum. However, a structure in which the deck material A and the joist material B are integrally connected by a stopper or a screw C is widely used.

Utility Kaihei 3-82755

  In the above connection structure, the deck material A and the joist material B are connected and fixed by pushing the screw C from the upper surface of the deck material A with a drill and screwing the lower end of the screw C to the inside of the upper surface D of the joist material B. However, even if the screw C can be pushed into the synthetic resin deck material A without any problem, the screw C and the deck material B are integrally screwed through the surface of the metal joist B. In this process, the tip of the screw C slides on the joist surface, and the hole may not be opened at an appropriate position, or the screw C may be broken. It was.

  In addition, when the operator screws the screw C into the surface of the deck material A, the screw C must be supported with the left hand until the screw C reaches a certain depth by the drill supported by the right hand. There is a problem that the fingertip comes into contact with the screw C that rotates at a high speed, and there is a danger if the safety is not sufficiently noted.

  Therefore, before the deck material A is connected and fixed to the joist B with the screw C, the diameter of the joist B is previously attached to the mounting surface D of the deck member A as shown in FIG. A guide hole E having a smaller inner diameter is provided, and when the deck material A is connected and fixed to the joist B, the guide hole E with the lower end pointed portion of the screw C inserted into the guide hole E. The process which made it easy to screw on the screw C by rotating and cutting the inner periphery of was added.

  However, providing the guide holes E in advance on the mounting surface D of the deck material A in this way requires work time for providing a large number of holes before the deck material A is mounted on the joist B. And there was a point that should be improved in terms of work efficiency.

  In order to eliminate this type of conventional problem, the present invention provides a metal frame in advance when connecting and fixing a plate material constituting a floor plate or a wall plate to a metal frame constituting a joist material or a pillar material. A plate and a metal frame that allow screws to be easily, quickly, safely, and securely inserted without the need to provide holes for guiding the screws so that they can be correctly inserted into predetermined positions. The purpose is to provide a connecting structure.

  The connection structure between the plate material and the metal frame according to the present invention is, as a specific means for that purpose, a plate material constituting a floor plate or a wall plate, and a metal plate constituting a joist material or a column material for fixing and holding these plate materials. A plurality of parallel frames along the length direction of the frame for temporarily holding the tip of the set screw into the recessed groove at the stop position and temporarily holding the frame at least on one side surface. It is characterized by having a vertical rib.

  The concave groove formed between the vertical ribs preferably has a valley shape in which the thickness of the central portion of the bottom surface facing the tip of the set screw is thinner than the plate thickness immediately below the base portion of the vertical rib.

  Locking protrusions for stabilizing the holding state of a screw inserted between any pair of vertical ribs are provided on the side surfaces of the respective vertical ribs along the longitudinal direction of the vertical ribs. Is preferred.

  The present invention is composed of a plate material and a frame for supporting the plate material, and the main application is a floor surface structure in which the plate material is used as a floor board such as a deck material and the frame is used as a joist. It is preferable to use it for the body.

  When the present invention is used for a floor surface structure in which a plate material is used as a floor plate such as a deck material and a frame is used as a joist material, the connecting means for the deck material arranged in parallel on the joist material is adjacent. It is preferable to include a screw holder for fixing the deck material between the connection side surfaces, and a set screw for screwing the screw holder to a joist having parallel vertical ribs.

  The specific structure of the screw holder includes a wall plate sandwiched between the side surfaces of both deck materials, a vertical hole for inserting a set screw provided in the center of the wall plate, and both deck materials on both sides. It is preferable to provide a connecting plate that is inserted into the locking groove.

  The connection structure of the present invention is a wall surface structure in which the plate material is used as a wall plate and the frame is used as a column material as another application other than using the plate material as a floor board and the frame as a joist. It can also be used.

  Furthermore, as another use, it can also be used for the ceiling structure which uses a board | plate material as a ceiling board and uses a flame | frame as a joist.

  The connection structure between the plate material and the metal frame according to the present invention includes, for example, a plurality of structures for stably guiding the lower end portion of the set screw into the recessed groove at the stop position on one side surface of the metal frame constituting the joists. Since it has parallel vertical ribs, the bottom edge of the set screw that penetrates through the plate material such as deck material and protrudes to the back side of the deck material goes into the groove between the vertical ribs. It can be inserted without requiring any force, and if the screw is pushed lightly from this state, the set screw is sandwiched between the vertical rib and the vertical rib, so the set screw is not supported by the fingertip However, it can be temporarily held in an upright state. If the joist has no groove with vertical ribs as in the present invention, a guide hole must be drilled in the joist metal plate in advance. Since it is not necessary to drill a guide hole in the joist member when inserting into the groove, the operation of temporarily fixing the set screw to the joist member is greatly improved.

  Further, in the connection structure of the plate material and the frame of the present invention, the thickness of the bottom surface contacting the tip of the set screw is the bottom surface of the concave groove between the vertical rib and the vertical rib provided on one side surface of the joists. Since the valley shape is thinner than the thickness of the base part of each vertical rib, when the set screw inserted in the concave groove between the vertical ribs is inserted and rotated by a drill, The thin bottom surface portion in the groove is drilled with a light force, and then the large thickness root portion along the length direction of the two vertical ribs is cut. Drilling can also be performed with a relatively light force, and drilling can be performed more easily than in the past.

  In addition, after the lower end of the set screw has passed through the bottom of the vertical rib as described above, the set screw screw engages with the inside of the thicker root portion, and a large pull-out is caused by a relatively large frictional force. Strength can be obtained. As a result, according to this connection structure, it is easy to penetrate the set screw with respect to the joist, and it is possible to obtain a high pulling strength after the penetration.

  The present invention is basically composed of a plate material constituting a building and a frame for supporting the plate material, but as a main application, the plate material is used as a floor board such as a deck material 1, The frame is preferably used for a floor structure used as a joist 5 for supporting the floor board.

  FIG. 1 is a cross-sectional view showing the most preferred embodiment of the floor structure according to the present invention. The deck material 1 is molded from a synthetic resin, and as shown in FIGS. The thing of the shape where the latching ditch | groove 4 provided with the hook-shaped latching | locking part 3 was established inside the side surface 2 is used.

And a plurality of vertical ribs 8 parallel to the length direction of the joists 5 on at least one support surface 7 of the stopper support surface 7. Is provided.

  Each of the vertical ribs 8 protrudes upward from the stopper support surface 7 so that the upper end is located at the same height as the floorboard support surface 6 of the joist 5, and the concave groove 10 between the vertical ribs 8. The width W of the screw is the same as or slightly shorter than the outer diameter of the set screw 9 for fixing the deck material 1 to the joist 5, and the pointed portion 17 at the lower end of the set screw 9 is easily inserted into the groove 10. The interval is set so that it is possible. In addition, on both upper side surfaces of each vertical rib 8, a locking protrusion for applying a pulling resistance to the set screw 9 when the set screw 9 is inserted into the recessed groove 10 between the vertical ribs 8. 25 is provided

  Further, in the lower end portions of these concave grooves 10, the thickness D of the central portion of the bottom surface 11 facing the lower end pointed portion 18 of the set screw 9 is thinner than the thickness E immediately below the root portion 8 a of the vertical rib 8. It has become a valley shape.

  As shown in FIG. 2, when the set screw 9 penetrates the deck material 1, the lower end pointed portion 18 of the set screw 9 is automatically guided into the concave groove 10 between the vertical rib 8 and the vertical rib 8. The screw portion in the upper portion of the pointed portion 18 is sandwiched between the vertical ribs 8, and the deck material 1 and the joist material 5 are temporarily held via the set screw 9.

  In this state, when insertion rotational force by a drill is applied to the set screw 9, the bottom surface 11 portion having a thin wall thickness D in the concave groove is first perforated with a light force, and subsequently along the length direction of the longitudinal rib 8. Since the root portion having a large thickness E is cut, the root portion having a large thickness E can be drilled with a relatively light force, and the drilling operation can be performed more easily than in the past.

  As shown in FIG. 4 a, when the set screw 9 is passed through the deck material 1, the lower end pointed portion 18 of the set screw 9 is not guided to the correct position between the vertical rib 8 and the vertical rib 8, and is slightly shifted. Even if it is, if the set screw 9 is pushed in strongly, the bottom surface 11 penetrates while the vertical rib 8 is inclined, and an appropriate fixed state can be obtained.
