Description

  The present invention relates to a fixture for fixing a floor board of a wood deck to a joist.

  The wooden deck is configured by laying floor boards such as wood, synthetic wood, metal or plastic drawing material on the horizontal joists, and the floor boards are fixed to the joists in some way.

  There are various fixing methods,

  As shown in FIG. 17, when the floor board of the wood deck is fixed to the joist, the joist is fixed to the joist with a screw from the surface of the floor board.

  Method 2 is a method of processing a groove on the side surface of a floor board material if it is wood, and a method of fixing a floor board formed with a groove on the side surface of metal or plastic to a joist using a metal fitting or a fastener. I used it. (For example, refer to Patent Document 1).

Patent Document 1 Japanese Patent Application Laid-Open No. 2003-301591 FIGS. 7 and 10

  Many people walk barefoot on the completed wood deck.

  It is dangerous to fix the joist from the floor board surface with wood screws, etc., because the screw head may be damaged by a screwdriver, etc., and it may jump out as a metal stab and cause injury. ,

  For any material such as wood, synthetic wood, metal, plastic, etc., a process for digging a groove is required to dig a groove in the side of the floorboard, and the equipment, processing time, and processing cost for processing the groove are required. It takes.

  Wood may be warped due to climate such as humidity, temperature, etc., and materials such as knots, etc.In other materials, warpage and bending occur at the time of production, generally thin and long materials are easy to bend, Even with materials that are lightly bent in the horizontal direction (to the extent that it can be forced by the force of the human body), it is necessary to spend extra time on the construction. The construction of the wood deck is not only a specialized carpenter, but also general amateur people are do-it-yourself For this reason, it is necessary to consider the construction so that non-specialists can easily construct.

  The present invention has been invented to solve these problems.

  In order to solve the conventional problem, the present invention is a fixing tool used in a plurality of sets for fixing a floor board to a joist, and is used in a state sandwiched between the floor board and the joist, thereby fixing the floor board and the joist.

  The fixing tool has a claw shape on a part of the side surface in the horizontal direction of the plate material, and there is a notch side by side on the side where the claw shape comes out.When the floor board is fixed to the joist through this fixing tool, A space formed by a notch is formed between the joist and the fixture, and the space is sized to receive the nail shape of the mating partner, and the fixture when the nail shape of the mating partner enters the space. In addition, the fixture has a hole for attaching to the joist, and the nail-shaped vertical direction inserted by opening this hole diagonally. The floor plate is fixed to the joist with the restraining force and the hole opened diagonally.

  The invention of claim 2 is intended to correct the light horizontal bending of the wood (to the extent that it can be forced by the force of the human body) and to make the wood deck assembly work easier. Since there is a projection 6, a claw having the same shape as the nail shape with the projection 6 to be assembled is inserted into the space 3 of the fixture, and a recess 7 in which the projection 6 is accommodated when the tip reaches the tip is provided. The projection 6 is caught in the recess 7 by pushing the claw 2 into the space 3.

  According to the invention of claim 3, the construction of the wood deck is not only a professional carpenter but also general amateur people are working by Sunday carpenters. In order to absorb the error due to the mounting variation of the fixing tool in the space formed by the nail shape and the notch where the nail shape enters, the gap between the nail 2 and the space 3a in which the nail 2 enters is shown in FIG. By providing G, it is possible to absorb a variation error when attaching the fixture.

  In the invention of claim 1, the fixture is assembled on both sides of the floor board and used in a state sandwiched between the floor board and joists.

  Since the floor board can be fastened to the joist with the vertical restraining force of the inserted nail and the hole opened in the diagonal direction, there is no need to tighten it with a wood screw from the floor board surface, and the thorns caused by tightening with the slave wood screw are the floor board surface In addition, since it is not necessary to machine grooves on the side of the floor board, the floor deck is fixed to the joists without special man-hours such as the cost of the groove machining, machine for machining, time, etc. Can be configured.

  Furthermore, when wood is used for the floorboard material, there is no need to machine grooves on the sides, so the construction material or the orderer can freely choose the desired material, such as grain, wood, etc. There is no need for time and processing costs become unnecessary.

  In the invention according to claim 2, the floor board is not always straight, but there are many floor boards with light bends (to the extent that they can be forced with human arms). The present invention is used in a state where it is sandwiched between a floor board and a joist, but since there is a recess 7 in the space 3 in FIG. 9, when the protrusion 6 at the tip of the nail 2 is pushed into the space, the protrusion 6 becomes the space 3. It is pressed by the dent 7 and can correct light bends of the floor board. When the light bend floor board is fastened to the joist, the floor board can be corrected. Is easy to install.

  In the invention according to claim 3, in order to construct the wood deck, a large number of the present invention are attached to the floor board. However, attaching the same as designed does not require a special technique, and a lot of time is spent. This is uneconomical. In particular, when a general amateur person installs it at a DIY carpenter, it is difficult to install it exactly as designed, and the installation error increases, so even if the installation error is large, it is necessary to configure the installation error as a wood deck. A gap that can be absorbed is required. By providing the gap G for absorbing the attachment error in the nail 2 and the space 3a in which the nail 2 enters, the operation can be advanced without being affected by the attachment error.

  In the following, with reference to the drawings, an embodiment of claim 1 will be described separately for each process.

  It is for constructing a wood deck by fixing a floor board to which a plurality of the present invention is assembled on a joist while fixing it to a joist with a space made of a step by a nail and a notch of the present invention and a joist attaching screw, It has the following structure.

  FIG. 1 is a perspective view seen from the back side for easy explanation of the overall view of the present invention.

  FIG. 2 is a perspective view of the surface of the overall view of the present invention.

  The structure of the present invention (fixing tool) will be described with reference to FIG. 1, FIG. 2, FIG. 7, and FIG. 9. FIG. , There is a step 33 which is a notch side by side on the side where the nail 2 comes out, and when the floor board is attached to the joist through this invention, the step 33 constitutes the space 3 in FIG. The space 3 formed by the step 33 is sized to receive the claw 2. Further, in the present invention, the floor 3 is attached to the floor board mounting hole 4 and the joist 11 in a direction perpendicular to the plane in order to attach to the floor board. Therefore, as shown on the left side of FIG.

  The implementation method of Claim 1 is demonstrated in order of a process.

  In the following description, the drawings after the reference number 3 will be described with the main body 1, the main body 1a, the main body 1b, the main body 1c, and the main body 1d attached to the floor board.

  Step 1 and FIG. 4 show how the present invention is attached to the floor board. The present invention is arranged on the floor board 10 so that the portion of the claw 2 faces the outside of the floor board 10 as shown in the figure, and a reference wall 12 is provided. Therefore, in order to keep the floor plate 10 parallel to the present invention, the arrangement position reference line 13 is determined according to the joist position only in the longitudinal direction, and fixed to the floor plate 10 with the floor plate mounting screw 8 through the floor plate mounting hole 4.

  At this time, the length of the floor plate mounting screw 8 should be such that the tip of the screw should not protrude from the floor plate 10 when tightened to the floor plate 10.

  As shown in FIG. 4, two main bodies 1 are attached to each floor plate as shown in FIG. 4, and the main bodies 1 are arranged and attached by the number of joists. See Figure 3

  FIG. 3 is a partial view of the floor board to which the present invention is attached as seen from the floor board side, but the joist drawing is omitted.

  The number of floorboards to which the present invention is attached is manufactured in the number necessary for constructing the wood deck.

  Step 2, Attaching the first floorboard to joist, FIG. 6 is a diagram showing only the cross section of CC in FIG. 5. FIG. 6 illustrates how the first floorboard is attached to joist, 6 On the left side, the main body 1c is fastened to the joist 11 with the joist mounting screw 9c through the joist mounting hole. Similarly, the main body 1d on the right side of FIG. 6 is also fastened with the joist mounting screw 9d using the joist mounting hole 5d The first floor board 10 can be fixed to the joist 11 without leaving a screw mark on the surface.

  Step 3, installation of the second and subsequent floorboards will be described with reference to FIGS. 7, 9, and 10.

  9 shows a cross section AA of the main body 1b and a cross section BB of the main body 1c in FIG. 5. The floor board 10 is the first sheet (the first floor board attached), and 10a is the second sheet (to be installed from now on). ) The second floor board 10a and the main body 1a, which are floor boards, are moved in the direction of arrow H to insert the claws 2 of the main body 1a into the space 3 of the main body 1. FIG. Represents.

  Since the portion of the nail 2 inserted is fixed to the floor board 10, it does not float upward (J direction) and is fixed to the joist.

  7, the floor board 10 is the first sheet (the floor board attached first), 10 a is the second floor board, the main body 1 a of the floor board 10 a is a cross-section of CC in FIG. 5, opposite to the inserted nail 2. The second floor board 10a can also be fixed to the joist with the pawl 2 and the joist set screw 9a of the main board 1b using the oblique hole of the joist mounting hole 5a of the main body 1a on the side.

  The cross section of the main body 1a in FIG. 7 represents the cross section at the position CC in FIG. 5, but it can be seen that the space 3 is secured when viewed at the position in FIGS.

  By repeating step 3 the required number of floorboards, it is possible to complete a wood deck without leaving a screw mark on the surface and without processing grooves on the side surface.

  FIG. 8 is a perspective view during assembly.

  The effectiveness of the nail 2 and the space 3 will be further described.

  Since the present invention is attached to the floor board with two joists, the floor board can be fastened to the joist using the diagonal holes and screws of the joist mounting hole 5 in FIG.

  FIG. 16 is a view in which the floor board 10a is attached to the joist with only the mounting holes in the joists. When the main body 1b on the floor board 10 side that has been installed is also fastened with the joist set screws 9b, the interval N between the floor boards is set. Need to take a big,

  Standards for commercial floorboard materials are not constant, so if the thickness of the floorboard changes, the design must be re-designed to take into account the spacing N according to the thickness. Also, a jig to keep the spacing N constant must be remade. Expenses and time are spent on things that are not directly related to the construction.

  Furthermore, in this state where the distance between the floor board and the floor board is wide, when walking barefoot, the toes easily enter the gap, and a safe state cannot be ensured.

  The presence of the nail 2 and the space 3 allows the interval to be maintained at the interval M regardless of the thickness of the floor board material, which saves extra costs and time, is more aesthetic and safe.

  A mode for carrying out claim 2 will be described with reference to FIGS. 7, 13, and 14.

  Wood also warps or bends in the manufacturing process even in materials such as synthetic wood, metal, plastic, etc., which may warp due to climate such as humidity and temperature, and materials such as knots.

  FIG. 13 is a diagram showing a bent floorboard, and the floorboard end surface P on the lower side of the floorboard 10a is open for bending.

  FIG. 14 is a reference diagram for explaining the case where the main body 1a has no protrusion at the tip of the claw 2 and the space 3 of the main body 1 has no dent.

  To fix the floor board in this state, even if the floor board is pushed in the direction of the arrow O in the state where there is no protrusion at the tip of the claw 2 and there is no dent in the space 3, it is returned in the R direction by the reaction force of the warp or the bending. 7. Push the floor board 10a with one hand in the direction of the arrow H, and while correcting it, the joist mounting screw 9 must be rotated with another hand to fix the floor board 10a. This is a big burden for the DIY carpenters.

  In order to eliminate this burden, description will be made with reference to FIGS. 7, 9, 10, and 13.

  FIG. 9 is a sectional view taken along the line AA of the main body 1b and the cross section BB of the main body 1c. FIG. 9 has a recess 7 in the space 3, so the projection 6 at the tip of the claw 2 is pushed in the direction of the arrow H. The projection 6 is held by the recess 7 in the space 3 and cannot be pulled out even if a force pulling in the direction opposite to the arrow H is applied.

  FIG. 13 When the floor board is bent and the floor board end face P is opened in the direction of arrow K, FIG. 10, the protrusion 6 is pressed by the recess 7 in the space 3, and the reaction force due to the bending of the floor board is eliminated or reduced. 7 It is not necessary to press the floor board 10a against the floor board 10 with one hand, and the main body 1a can be fixed with the joist mounting screw 9a. Since the work can be performed with the floor board pushed in and straightened, the power to correct the floor board and the work of tightening the screws are distributed and work can be performed without any change from normal floor board construction. With one-time construction such as Do-it-yourself carpenters, there are advantages such as not having to prepare unnecessary tools later and being able to continue working alone.

  The inclined surface 14 in FIGS. 9 and 10 is a relief for the protrusion 6 to easily enter the recess 7 in the space 3.

  Form for implementing claim 3

  In order to construct a wood deck, the present invention, which uses a large number of floorboards, is attached to a single floorboard twice the number of joists, but it is necessary to have specialized technology to install it exactly as designed. A lot of time is spent even with specialized skills.

  The work environment is often outdoors, and even in the bad work environment such as windy, snowy, rainy, cold, hot, cold, etc., even professional engineers will have uneven installation.

  In particular, when a general amateur person constructs with a DIY carpenter, it is difficult to install without any difference as designed regardless of the work environment, and the installation error becomes large.

  Even if the floor board is assembled in a state where the mounting error is large, the position of the nail and the space does not match, and it can not be configured as a wood deck.Therefore, a gap that can absorb the mounting error is required to configure as a wood deck even if the mounting error is large is there.

  In the present invention, when the gap G between the claw 2 and the space 3a in which the claw 2 enters is set (the claw 2a and the space 3 have the same relationship), the attachment position error of the main body 1 and the main body 1a attached to the floor board is shown in FIG. Regardless of the position of the reference line 13, if it is within the range G in FIG. 5, the floorboard can be easily arranged, and the wood deck can be configured without being affected by the mounting error.

  The range of the gap G is determined by the designer's judgment because it is influenced by the design contents such as the size of the present invention, the working environment to be used, and the technical level of the worker.

  Fig. 8 shows the process of constructing the wood deck. As shown in Fig. 8, the surface of the floorboard can be finished to a smooth surface without any screw marks and without special processing on the floorboard. it can.

  FIG. 11 is a diagram showing a state in which the floorboards are assembled, in a cross section of AA and a cross section of BB in FIG.

  FIG. 12 is a view showing only the cross-section of FIG.

  In the above description, screws are used. However, if the main body and the floorboard, and the main body and joists are fixed, they may be fixed with screws, for example, nails or adhesives.

  The present invention is not limited to the embodiments described above.

  “Other embodiment 1”

  The floor board material that is bent greatly cannot be used as it is,

  FIG. 15 shows that the floor board material that cannot be used as the floor board material is cut and deleted, and the floor board 10 and the floor board 10b are used as two floor board materials. The mating surface 15 is a line that represents the surface of the floor plate 10 and the floor plate 10b that are joined to each other using the floor plate mounting screws 8 and 8b.

  If the floorboard has a length that spans between joists, mill ends can also be used.

  “Other embodiment 2”

  Although the embodiment of the present invention has been described using floor boards and joists to constitute a wood deck, it is possible to construct walls using side wall materials instead of floor boards and studs instead of joists. Moreover, if a ceiling material is used, a ceiling can be comprised.
