Figure 14 and Figure 15 represent the pedestal 3b that contacts to earth of other embodiment.The difference of the embodiment of present embodiment and Figure 12 and the pedestal that contacts to earth shown in Figure 13 is: in the occasion of this pedestal 3a that contacts to earth, be equipped with 4 in its bottom surface along its circumference and be hemispheric protuberance 32b substantially, these 4 protuberance 32b are that the center keeps symmetry with the axle center of interstitial hole 31b.
Owing to be formed with a plurality of protuberances such as above-mentioned ring this protuberance 32a or hemisphere protuberance 32b in the bottom surface of the pedestal that contacts to earth, the area that contacts to earth of above-mentioned like this contact to earth pedestal and basic floor is less, thereby can will open by the load mark that bolt bore, because the elasticity (sinking) that it has appropriateness can obtain to reduce the impact sound on floor, the particularly weight effect to the impact sound on floor like this.Preferably the height of raised part is 2～4mm.If the height of raised part is too small, then reduce the effect of the impact sound on floor just relatively poor, and if above-mentioned height is excessive, then the sinkage on floor is bigger, owing to can not obtain stable walking feel, or ground is easy to generate reasons such as height difference, so preferably do not adopt above-mentioned two kinds of situations.
In addition, bolt needn't be limited to real core form according to the mode of previous embodiment, and it also can adopt the hollow bolt of being made by hollow tube.This hollow bolt can be made by lower cost than the bolt of real core, and it also helps suppressing the propagation of floor impact sound sound in addition.
Figure 16 represents that the hollow bolt and the pedestal that contacts to earth are in an embodiment of stationary state.Bolt 4b is made by the metal hollow tube with central through hole 43, and the mode in its bottom by the processing of buckling is formed with outstanding toward the outer side annular flange portion 5b.The pedestal 3c that contacts to earth is made of near the receptacle 34 that has larger-diameter circular body 33 and stretch out the pars intermedia of this main body 33.In addition, be formed with recess 35 according to its opening mode up in the above-mentioned receptacle 34, the flange part 5b that this recess 35 is used for being formed at the bottom of bolt 4b inserts in it, is formed with the fitting portion 36 that stretches out according to certain size on the sidewall apical margin of this recess 35.The effect of this fitting portion 36 is that the flange part 5b among the bolt 4b is pressed against recess 35 inside, and can not extract the flange part 5b of bolt 4b from recess 35.
The occasion of the foregoing description also can adopt following mode, promptly make the outer edge surface and the inner edge surface on the top of hollow bolt 4 form hexagonal configuration by deep-draw processing, or above-mentioned inner edge surface is processed into hexagonal configuration by deep-draw, thereby the front end of throws such as hex wrench can be embedded the top of above-mentioned bolt 4b.In above-mentioned occasion, can form the groove 6 (with reference to Fig. 3) on the end face of bolt or not form this groove 6, but in the occasion that forms groove 6, hex wrench and screwdriver all can use.In addition, also can form the through hole vertically of the pars intermedia that connects the pedestal 3c that contacts to earth, that the mode that extends to the side from above-mentioned through hole at the bottom surface of circular body 33 edge is is radial forms a plurality of grooves (such as, cross shape).Thus, by inject bonding agent from the top, then bonding agent can flow downward from the inside of the central through hole 43 of hollow bolt 4b, then permeates in the groove of the above-mentioned pedestal 3c bottom surface of contacting to earth, so also can contact to earth pedestal 3c and basic floor A is bonding.
In the manner described above, because combined support feet of the present invention will be arranged at needle-like protuberance on its base plate end face as the fixed mechanism of floor board block, this combined support feet can be used for the construction of double floor, like this when splicing floor block with tongue and groove, the mode that can obtain good operation is easy to this floor board block is fixed on the combined support feet, but thus the reduction of erection time, reduce construction cost.
In addition, because the effect of needle-like protuberance, can suppress to support and be fixed in moving of floor board block along continuous straight runs on the combined support feet of the present invention, can prevent lateral shift really like this.Length or the less occasion of fineness degree at above-mentioned needle-like protuberance, because it is relatively poor to floor board block opposing effect vertically, and under the situation that the bed knife that does not make above-mentioned relatively horizontal direction changes, can dismantle floor board block repeatedly, like this when splicing floor block with tongue and groove, even error appears in position, still be easy to arrange correction, also reusable in addition floor board block.
Therefore, after carrying out the double floor construction, connect up carrying out underfloor, pipeline etc. newly is set, or when the operation of below, floor such as changing, equally also comparablely is easier to take off floor board block, after above-mentioned operation finishes, need not to change parts such as base plate, and, just can once more base plate and floor board block be fixed by using the mode of original combined support feet as it is.So the present invention newly establishes and change the construction of movable floor of operation for wiring of often carrying out underfloor etc. effective especially.
In addition, because the dismounting between base plate and the floor board block is more or less freely, even in the occasion that it is dismantled repeatedly, its bed knife still remains unchanged substantially, and combined support feet of the present invention so also can in statu quo recycle.Such as, arrange in short floor construction process of time limit at such its of emergency dwelling or makeshift stage, combined support feet of the present invention or double floor composite member can be adopted repeatedly, and operating expenses reduced levels can be controlled at.
Have again, in the occasion that adopts combined support feet of the present invention, this combined support feet has the base plate that is provided with the needle-like protuberance and is used for the guiding protuberance of floor board block location, because with after above-mentioned guiding protuberance aligns, be easy to floor board block is positioned on the base plate, the operation of floor board block is more prone to, can further improve workability.
