JP5155347B2 - Intersection support floor post - Google Patents

Description

  The present invention is an improvement of a plastic floor post used as a building material. More specifically, the intersection of the corners of the floor material can be fixed securely, and assists in the laying of the floor material. Further, the present invention relates to an intersection support floor post that can be manufactured at a low cost.

  As is well known, in recent floor construction, in order to minimize the work of woodwork such as bundling at the site, the floor is adjusted using a height-adjustable floor bundle (so-called “floor post”) using an adjusting bolt mechanism. The construction method to be constructed is becoming popular.

  By the way, in this floor construction method, when laying each floor floor configured in a unit type on the floor, in the place where the corners of these floor panels are close to the bowl shape, the top plate of the floor post is cross-shaped. In addition to forming the partition plate, the corner portions of the floor panel were placed on the top plate, and each corner end portion was pressed and clamped from above (see, for example, Patent Document 1).

  However, in such a conventional floor post, since the head portion of the bolt for tightening the floor panel and the screw portion are integrally formed, it is necessary to create a molding die having a complicated shape. However, there is a problem that the molding cost increases.

  In addition, when the top plate of the floor post is made of metal, due to its rigidity, the floor post cannot absorb the impact received from the top surface of the floor material, and the impact travels directly through the floor post to the slab as it is. There was a risk of noise and vibration damage going downstairs.

  Furthermore, although a metal plate is used as a washer member for pressing the corners of the floor material (see, for example, Patent Document 2), the metal plate material is punched to form this washer. There was a complaint that processing such as pressing and pressing was difficult, and the manufacturing cost of the parts was increased.

  The mode for carrying out the present invention will be described in more detail with reference to the drawings specifically illustrated as follows.

  An embodiment of the present invention will be described with reference to FIGS. 1 and 2, what is indicated by reference numeral 1 is a floor receiving plate, what is indicated by reference numeral 2 is a screw rod, what is indicated by reference numeral 3 is a base member, and what is indicated by reference numeral 4 is a floor material. The reference numeral 5 indicates a plastic washer, and the reference numeral 6 indicates a bolt member.

  Therefore, the floor post in the present embodiment is to support and fix the intersection where each corner portion 41 of the square floor material 4 having a predetermined thickness is close to the bowl shape. First, the floor receiving top plate 1 for supporting and fixing the floor material 4 is provided at the upper end, and the base member 3 placed on the slab is disposed at the lower end (see FIG. 1). The floor backing plate 1 of this embodiment is produced by injection molding a plastic material (for example, polypropylene (PP)).

  Further, a rod-like screw rod 2 having a screw screw 21 formed on the outer periphery thereof is integrally fixed to the lower surface of the floor receiving top plate 1 by ultrasonic welding, an adhesive or the like, and a nut screw portion 31 formed on the base member 3. Can be screwed together. In the present embodiment, the screw rod 2 and the base member 3 are manufactured by injection molding a thermoplastic material (for example, polypropylene (PP)).

  And it is the structure which can raise / lower the level of the said floor receiving top plate 1 by rotating this screw rod 2 forward / reversely. At this time, the stopper 22 can be screwed onto the screw rod 2 to prevent rotation and fix the position.

  Next, a cross-shaped partition plate 11 is formed on the upper surface of the floor receiving top plate 1, and spacer projections 11 a are formed on the side wall surface of the partition plate 11. In the present embodiment, the partition plate 11 is formed integrally with the top plate body, and the ridges extending in the vertical direction are formed on both sides of the side wall surface at two locations (end edge portion and central portion).

  Further, a cap nut 12 is formed at the center of the intersection of the partition plate 11. A female thread is formed on the inner surface of the cap nut 12.

  Next, as shown in FIGS. 3 and 4, at least ribs 51 are formed on the surface of a plastic washer 5 injection-molded into a flat plate made of a plastic material (for example, polyamide (PA)), and at the center. Opening hole 52 is opened. In this embodiment, the plastic washer 5 can be made circular, and the ribs 51 can be formed radially and concentrically, and appropriate rigidity can be imparted equally.

  Then, the male screw portion 62 of the bolt member 6 having the dish-shaped head portion 61 is inserted into the fastening hole 52 of the plastic washer 5 and screwed into the cap nut 12 of the floor receiving top plate 1. it can. In the present embodiment, when the head 61 of the bolt member 6 is fitted in the fastening hole 52 of the plastic washer 5, the lower end of the head 61 is configured to protrude from the bottom surface of the plastic washer 5. (See FIG. 5), sliding friction between the head 61 and the inner peripheral surface of the fastening hole 52 can be reduced, and the vicinity of the fastening hole 52 can be easily bent downward.

  At this time, since the cross-sectional thickness gradually decreases in the vicinity of the edge of the fastening hole 52 of the plastic washer 5, it is possible to easily deform the portion when the bolt member 6 is screwed. . Note that the head 61 of the bolt member 6 protruding from the fastening hole 51 does not interfere with the notch 41 of the floor material 4.

  And the notch part 41a is formed in the front-end | tip of the corner part 41 of the said floor material 4, and the seating surface 41b is formed in the upper surface of the said corner part 41 vicinity (refer FIG. 6). The floor material 4 is made of MDF (medium-density-fiber-board), and is formed in a square of, for example, 500 mm and a thickness of 30 mm. Further, the shape of the seat face 41b may be larger than the cross-sectional shape of the plastic washer 5, but it is particularly preferable that the shape is the same, so in this embodiment, it is cut into an arc shape.

  By configuring as described above, when each corner portion 41 of the floor material 4 is placed on the upper surface of the floor receiving top plate 1, a predetermined distance is provided between the side surface of the floor material 4 and the partition plate 11. Space can be formed (see FIG. 7), positioning work can be facilitated, and contact between the side surfaces of the adjacent floor members 4 can be prevented, and noise and impact propagation can be reliably prevented. When the floor material 4 is made of MDF, it has a high expansion rate and easily expands. However, when the floor material 4 is expanded, the side surface makes contact with the spacer protrusion 11a so that the pressing force can be absorbed.

  Thereafter, the bolt member 6 is screwed into the cap nut 12 of the floor receiving top plate 1 to move the head 61 of the bolt member 6 downward, so that the fixing hole 52 of the plastic washer 5 is formed. The peripheral edge portion can be slightly bent downward to press and urge the lower surface of the plastic washer 5 against the seating surface 41b (see FIGS. 8 and 9). Moreover, since the plastic washer 5 has elasticity, even if there is a minute difference in the level between the adjacent floor members 4, it can be uniformly pressed.

  In addition, since the space created inside the notches 41a of the floor material 4 facing the bowl shape is expanded by forming the spacer protrusion 11a, an allowable space for minute bending of the plastic washer 5 is increased. The pressing force can be increased by increasing the pressure. As described above, the floor material 4 can be sandwiched between the floor receiving top plate 1 and the plastic washer 5.

  The floor post of this embodiment can be used as shown in FIGS. 10 and 11 to lay the floor material 4 on the slab. Specifically, first, the screw screw 21 of the screw rod 2 is screwed into the nut screw portion 31 of the base member 3, and the upper surface level of the floor receiving top plate 1 is adjusted while rotating, and the stopper 22 is screwed into position. To confirm.

  Next, the base member 3 is placed at a predetermined position on the slab determined by surveying or the like and fixed with an adhesive. At this time, the direction of the partition plate 11 is also matched.

  Then, the corner portion 41 of the floor material 4 is placed on the upper surface of the floor receiving top plate 1 divided into four parts, and the four floor materials 4 are placed in close contact with each other in order. Thereafter, the plastic washer 5 is placed in a fitted state on the seating surface 41b, and the male threaded portion 62 of the bolt member 6 is inserted into the fastening hole 52 of the plastic washer 5, so that the floor support Screw into the cap nut 12 of the plate 1.

  As described above, the floor material 4 can be sandwiched between the floor receiving top plate 1 and the plastic washer 5 to complete the laying of the floor material. In addition, on the wall side of the room where only two corners of the floor material 4 are close to each other or in the corner of the room, a normal floor post having a wooden plate or the like disposed on the top plate can be installed and supported. .

  In this embodiment, as shown in FIG. 12, a taper is formed on the bottom surface of the plastic washer 5 to increase the thickness from the fastening hole 52 to the outer peripheral edge, while the corner portion 41 of the floor material 4 The seating surface 41b can be formed with an inclination that increases in thickness on the outside.

  By doing so, the positional displacement of the plastic washer 5 is prevented, and the floor members 4 are drawn toward each other so that the floor member 4 can be locked more reliably.

  Further, in the present embodiment, as shown in FIG. 13, the protrusion 53 can be formed on the bottom surface of the plastic washer 5, and the gripping surface 41b can be gripped more strongly.

  The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the description of “Claims”. The screw rod 2 fixed to the lower surface of the top plate 1 has a male screw formed on the base member 3 side, regardless of whether it is a male screw or a female screw, so that both members can be screwed together. Also good.

  Moreover, the shape of the floor receiving top plate 1 is not limited to a circular shape, but can be changed to a polygon such as a quadrangle. Furthermore, the material used for the floor receiving top plate 1, the screw rod 2, and the base member 3 is not limited to polypropylene (PP), but employs a thermoplastic resin such as polyethylene (PE), polyethylene terephthalate (PET), or vinyl chloride. be able to.
