Description

[Detailed explanation of the idea] This idea is about independent foundations.

Independent foundations for buildings are generally made of concrete or reinforced concrete, but in recent years, independent foundations have been made of steel for the purpose of saving labor and speeding up construction. .

The above-mentioned steel independent foundation generally has a steel base plate installed on the top surface of the footing buried in the soil, and a cylindrical steel base that is erected on the top surface of the base base and has a threaded part formed on the inner peripheral surface. A steel support shaft with a threaded portion formed on the outer circumferential surface and screwed into the support shaft so as to be able to move up and down, and a steel support shaft that is rotatably fitted to the upper end of the support shaft, It consists of steel supports that support a part of the floor. This independent steel foundation is constructed by placing the board on the top of the footing, raising the support shaft, pressing the support material against the support shaft, nailing the support material to the support shaft, and supporting the support shaft with the support shaft. Many of them were designed to take the load of heavy pulling.

However, with the above-mentioned independent foundation, if a part of the support material is deformed and moved upward due to the load of the building after the floor construction, or due to warpage or warping of the flooring material, the support material will be deformed and moved upward. Due to the fitting gap due to the rotatable structure of the material and the support shaft, there are drawbacks such as creating a creaking sound when stepping on the floor or causing the floor to rumble.

This idea was made in view of the above drawbacks,
By configuring the support material that supports horizontal materials such as large-scale materials to be fixed at the required height using a screw mechanism,
To provide an independent foundation hardware capable of fixing a supporting material in close contact with a horizontal member, and preventing the deformation of the horizontal member and causing no floor squeaks or floor noises.

This invention will be explained below based on embodiments shown in the drawings.

Figures 1 to 3 show an embodiment of this invention, in which the independent basic hardware A consists of a square metal substrate 1 and a cylindrical metal substrate erected in the center of the upper surface of this substrate 1. A support column 2, a metal support shaft 3 inserted into the support column 2 so as to be movable up and down, and a metal support member with a side U-shape integrally fixed to the upper end of the support shaft 3 by welding or the like. It is mainly composed of 4.

A plurality of through holes 1a are formed in the substrate 1, and a large number of pointed protrusions 1b are formed on the lower surface of the substrate 1. Further, a protective layer 2a such as a resin coating layer is formed on the outer peripheral surface of the support column 2. Furthermore, a screw mechanism N is provided at the upper end of the column 2 for fixing the support shaft 3 to the column 2 in a state where it extends a predetermined length above the column 2. This screw mechanism N
is an external thread 2b formed on the outer peripheral surface of the upper end of the support column 2.
It is comprised of a union nut 5 which is screwed into the support shaft 3, an adjustment nut 6 which is screwed into a threaded portion 3a formed at the lower part of the outer peripheral surface of the support shaft 3, and a fixing nut 7. A flange portion 6a is formed on the lower outer periphery of the adjusting nut 6, and the outer diameter of the flange portion 6a is made approximately equal to the lower inner circumferential diameter of the union nut 5, and the outer diameter of the upper portion of the adjusting nut 6 is The diameter is approximately equal to the inner diameter of the inward flange 5a formed on the upper part of the union nut 5. That is, the adjustment nut 6 is brought into contact with the upper surface of the support 2, the union nut 5 is screwed into the external thread 2b of the support 2, and the inward flange portion 5a of the union nut 5 is brought into contact with the flange portion 6a of the adjustment nut 6. This allows the adjustment nut 6 to be held down to prevent the support shaft 3 from rising. Further, in the figure, reference numeral 4a indicates a hole for passing a nail formed in the side plate of the receiving member 4, and reference numeral 8 indicates a resin sliding member disposed between the adjustment nut 6 and the support column 2.

FIG. 2 shows a state in which the floor of a house is supported using the above-mentioned independent foundation hardware A. The board 1 is installed on the upper surface of a footing F below a horizontal member 11 such as a large drawer that supports a part of the floor 10 of a house. The base plate 1 and the support pillar 2 are formed by a concrete base 1 that covers the periphery of the base plate 1 and the lower part of the support pillar 2.
2, and an embankment is made to cover the footing F and the concrete base 12. In addition,
When fixing the board 1 on the footing F, the support shaft 3 is housed in the support column 2, and the position of the receiving material 4 is set below the position where the horizontal material 11 such as a large underwriter is to be placed.

To support the large puller 11 with the independent base hardware A, first remove the union nut 5 from the external thread 2b of the support shaft 2, as shown in Fig. 2, and after freeing the vertical movement of the support shaft 3, Raise the shaft 3, fit the support member 4 into the cross member 11, and tighten the adjustment nut 6 to the support column 2.
The receiving member 4 is held by the structural member 11 while being screwed into contact with the upper end surface of the member 11. Next, screw the union nut 5 into the external thread 2b of the support column 2, and tighten the adjustment nut 6 with the inward flange 5a of the union nut 5.
The support shaft 3 is fixed by holding down, the cross member 11 is supported, and then a nail is driven into the cross member 11 through the hole 4a of the receiving member 4 and nailed. Note that the fixing nut 7 is brought into contact with the adjusting nut 6 and presses the adjusting nut 6 as shown in FIG.

When the horizontal member 11 is supported by the independent basic hardware A as described above, the support shaft 3 is prevented from vertical movement by the screw mechanism N, so the support shaft 3 prevents the horizontal member 11 from warping in the vertical direction. do. Therefore, even if the floor is stepped on, no squeaks or the like will be generated. In addition, even if the floor 10 or the cross member 11 is bent due to the weight of the building after floor construction, or the cross member 11 is warped over time, it is possible to remove the union nut 5 from the external screw 2b and tighten the nut. By turning 6 and 7, the support shaft 3 can be moved up and down, and the height position of the receiving member 4 can be made to correspond to the deformation of the cross member 11. Furthermore, since there is a protective layer 2a around the outer periphery of the pillar 2, the pillar 2 will not be corroded by moisture in the embankment. Note that the protective layer 2a may be formed by wrapping a waterproof tape around the outer periphery of the support 2, or if the support 2 is made of a material that does not easily corrode or is formed of a lining steel pipe, the protective layer 2a may be formed by wrapping a waterproof tape around the outer periphery of the support 2. It can be omitted. By the way, it goes without saying that this invention can be applied to all types of foundations with different depths by appropriately setting the lengths of the pillars 2 and support shafts 3 in accordance with high foundations and deep foundations. Furthermore, in terms of construction,
A moisture-proof sheet is sometimes laid on the embankment under the floor for the purpose of moisture prevention, but according to this idea, what protrudes above the embankment is the pillar 2, and the outer diameter of this pillar 2 is different from the conventional concrete independent one. Since it is smaller than the width and depth of the foundation, it does not become a hindrance when installing the heat insulation sheet. Therefore, the work of laying the moisture-proof sheet becomes much easier.

By the way, if the upper surface of the footing F is inclined with respect to the horizontal plane S as shown in FIG. 4, there is a possibility that the substrate 1 cannot be installed horizontally. in this case,
It is preferable to drive some of the protrusions 1b on the lower surface of the substrate 1 into the footing F and install the substrate 1 horizontally. After this, fresh concrete is poured around the substrate 1 to form a concrete base 12. Incidentally, in the above case, a gap is created between the substrate 1 and the footing F, but this gap can be easily filled by pouring fresh concrete through the through hole 1a of the substrate 1. Note that even if a gap occurs between the substrate 1 and the footin F when the upper surface of the footin F is horizontal,
Of course, the gap can be closed by the inflow of fresh concrete from the through hole 1a.

In the above embodiment, the adjustment nut 6 is held down by the union nut 5, but the height of the union nut 5 is increased to reduce the inner diameter of the inward flange portion 5a, so that the upper surface of the fixing nut 7 is turned inward. It may be configured to be held down by the flange 5a. Furthermore, by forming a number of screw holes in the board 1, inserting bolts into each of these screw holes, and changing the vertical positions of the bolts, the board 1 can be formed on the footin F.
It may also be configured so that it can be installed horizontally.

As explained above, this idea consists of a board installed on top of the footing, a hollow support on this board,
The structure consists of a support shaft inserted into this support shaft, a support material integrated into the upper end of this support shaft, and a screw mechanism that fixes the support shaft of the support shaft in the required position, so the support material can be used as a horizontal material such as a large pull. By fixing the base plate to the footing and fixing the support shaft with a screw mechanism, the horizontal member can be supported, and it also prevents the horizontal member from vertically deforming and prevents the floor noise that conventionally occurs. Can be done. It is also much easier to construct than traditional concrete foundations. In addition, even if the horizontal members are deformed due to the load of the building after floor construction or due to deformation of the horizontal members over time, the above deformation can be absorbed by moving the support shaft up and down using a screw mechanism and moving the receiving materials up and down. At the top, the cross members can be supported.
