BACKGROUND OF THE INVENTION
The present invention relates to a floor support member suitable for installing an exterior floor material on an underlying floor.
[0002]
[Prior art]
In recent years, wooden floor materials are used not only indoors but also as wooden decks etc. outside buildings by using highly durable wood. When installing this flooring on a rooftop or the like, as shown in FIG. 6, a waterproof layer 52 is applied to a housing surface 51 such as a rooftop, and concrete 53 is laid on the top surface to protect it. A hole 54 is drilled in the concrete 53. The hole 54 is filled with an adhesive such as epoxy, and a bolt or the like that becomes the leg 55 is vertically fixed to the concrete 53 and fixed to the concrete 53, and then a joist material 56, a large pulling material or the like is attached to the upper portion of the leg 55, The wooden deck material 57 is fixed to the upper surface with nails, screws or the like and assembled.
For example, Patent Document 1 and Patent Document 2 are known technical documents of such floor support members.
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 10-227089 [Patent Document 2]
Japanese Patent Laid-Open No. 2000-120253
However, recently, there is a case where the waterproof layer is left exposed without laying concrete on the waterproof layer in order to reduce the weight of the building or shorten the construction period. In such a case, if a bolt or the like that becomes a leg is stood up, a hole is formed in the waterproof layer, which causes water leakage.
Therefore, as shown in FIG. 7, a bolt or the like serving as a leg 63 is inserted and fixed to a rectangular base material 62 having a hole 61, and the base material 62 is fixed onto the waterproof layer 64 with an adhesive or the like. A method of fixing the legs 63, a so-called laying method is employed. In addition, there are increasing cases of adopting a double floor system in order to improve floor sound insulation performance and floor heating in the room. After installing the fixed base material on the frame surface, the flooring method is adopted in which the joist is fixed on the upper part and the wooden or PVC flooring is stretched.
[0005]
[Problems to be solved by the invention]
The above-mentioned laying method can be easily constructed without damaging the housing surface, but the top surface of the rooftop is often provided with a water gradient so that rainwater etc. can flow easily. There are uneven surfaces or cracks, and if a base material is installed at such a location, the bolts that become the legs will also tilt.
Therefore, in order to install the flooring horizontally, for example, a wedge-shaped spacer was inserted on the lower surface of the base material, or mortar was poured on the housing surface to adjust it to be horizontal. In this case, there is a possibility that the spacer may come off due to vibration or an external force, and there is a problem that construction takes time.
[0006]
In view of the above problems, the present invention can be laid without embedding and fixing bolts or the like on the frame surface, and even if the frame surface has an inclination such as a water gradient, unevenness or cracks, the legs can be easily placed vertically. A floor support member that can be held in a horizontal direction and can be applied horizontally to a flooring is provided.
[0007]
[Means for solving problems]
In order to solve the above-described problems, the present invention forms a through-hole through which a leg member can be loosely inserted in a base material serving as a leg seat in the vertical direction, and slides the upper and lower surfaces around the through-hole in a spherical or arcuate shape. An upper sliding member that is formed as a surface portion, has a leg member inserted into the through-hole, and has a lower surface corresponding to the sliding surface, and a lower sliding member that has the upper surface corresponding to the corresponding sliding surface. In the floor support member configured to press the upper and lower surfaces around the through hole of the base material, the periphery of the opening of the through hole on the lower surface of the base material is recessed upward in a square hole shape, and the inside of the depressed bottom surface is spherical or thru The floor supporting member is formed by forming a downward sliding member that is formed in an arcuate surface shape and is fitted in the recessed portion into a square shape.
In addition to the above-described configuration, the present invention has a structure in which the periphery of the opening of the through hole on the upper surface of the base material is recessed into a square hole shape, and the inside of the recessed bottom surface is formed into a spherical or arcuate surface and is fitted into the recessed portion. The sliding member is also formed in a square shape.
Further, in addition to the above configuration, a downward sliding member is attached to the lower end portion of the leg member, and a rectangular groove into which a nut can be fitted is formed on the lower surface of the downward sliding member.
[0008]
In this way, the leg member can be fixed at an appropriate angle with respect to the base material, and the leg member can be held vertically even when the base material is installed at an inclination.
Also, when changing the angle between the base member and the leg member, the leg member can be firmly fixed to the base member by clamping the base member with a nut using a sliding member.
The through hole of the base material is preferably formed so as to be a long hole in at least one direction, or formed with a diameter through which the leg member is loosely inserted in the entire circumferential direction.
Further, the leg member and the sliding member, in particular, the lower sliding member may be integrally formed, thereby reducing the number of parts and obtaining the same effect as described above.
[0009]
