Description

Aerial leveling member for ground

Technical Field

The utility model relates to a building element especially relates to a built on stilts leveling member of ground.

Background

High-requirement residential building ground engineering puts higher functional requirements on floor slabs; the floor slab not only needs to meet the safety requirement of bearing, but also needs to meet the functions of heat preservation, energy conservation, sound insulation and noise reduction of the floor slab, in the prior art, the purpose is achieved by using an overhead floor slab, and the leveling operation of the existing overhead floor slab is difficult and the time spent is long.

For example, the "SI system dry type overhead floor heating system" disclosed in the chinese patent document has a publication number of CN205296694U, and a ground heating layer, a pressure-bearing layer, and an overhead layer are sequentially disposed between the decorative layer and the load-bearing layer from top to bottom, and the overhead layer includes height-adjustable supporting legs mounted between the pressure-bearing layer and the load-bearing layer; through the adjustment of this supporting legs, can change the height of bearing layer, however, its shortcoming is that, after the bearing layer installation, if the ground is uneven, it is difficult to adjust again, if want to adjust, then need dismantle the bearing layer, it is longer to spend time.

Disclosure of Invention

The utility model relates to an overcome prior art, built on stilts floor leveling difficulty, the longer problem of spend time provides a built on stilts leveling member of ground, can carry out high fine setting to it after ground base plate installation is accomplished to guarantee ground relatively level everywhere, and convenient operation saves time.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model relates to an aerial leveling spare of ground, including nut, screw rod and base, screw rod upper portion is equipped with the external screw thread, be equipped with in the nut with the internal thread of screw rod adaptation, the nut includes nut upper portion, nut lower part and brace table, the brace table is located between nut upper portion and the nut lower part to the external diameter of brace table is greater than the external diameter on nut upper portion, brace table and the downside contact of ground base plate, nut upper portion is located ground base plate to be equipped with the adjustment tank in the nut upper portion, the lower part of screw rod with the base links to each other, side contact on base and the structural floor.

The leveling piece is arranged between the ground base plate and the structural floor slab, and the height is adjusted by screwing the screw cap and the screw rod; the support table has a supporting function on the ground base plate, after the base plate is installed on the leveling piece, as the upper part of the nut is positioned in the ground base plate, the height position of the nut can be adjusted by inserting a wrench or a screwdriver into the adjusting groove, and therefore the leveling of the ground base plate is achieved.

Preferably, the ground aerial leveling member further comprises a locking cover positioned above the screw cap, the lower part of the locking cover is connected with a locking screw, the upper end of the screw is provided with a locking screw hole, the locking screw is installed in the locking screw hole in a matching manner, an elastic washer is arranged on the outer side of the locking cover, and a locking adjusting groove is formed in the locking cover; because the brace table with the contact of ground substrate board, ground is at the in-process of long-time use, because the constantly change of floor load, can produce the power of horizontal direction between ground substrate board and the brace table to lead to the nut to become flexible gradually, and in this scheme, through with locking lid with the screw rod is fixed, when leveling a department and receiving the load that comes from the floor, the load of horizontal direction can by the elastic washer shares, thereby makes the horizontal direction's that receives on the brace table load reduce, thereby avoids the nut not hard up as far as possible, simultaneously, the cooperation of locking screw rod and locking screw hole can share the vertical load that receives on the screw rod again, thereby avoids the screw thread to damage the inefficacy when using for a long time as far as possible.

Preferably, the outer diameter of the elastic washer is gradually reduced from top to bottom; in the scheme, when the locking cover gradually moves downwards, the extrusion between the locking cover and the ground base plate can be gradually increased, so that the locking cover can be ensured to share more loads in the horizontal direction.

Preferably, a secondary locking piece is arranged on the lower side of the locking cover; the secondary locking piece can lock the nut, so that the situation that the nut rotates to cause height change of the ground base plate at the position is avoided.

Preferably, the shape of the secondary locking piece is matched with that of the adjusting groove, a secondary locking groove is arranged in the secondary locking cover, and the secondary locking groove is positioned below the locking adjusting groove and is smaller than the locking adjusting groove in size; the secondary locking groove is arranged below the locking adjusting groove, so that the structure space can be saved, the device structure is more compact, and the size of the device is smaller than that of the locking adjusting groove, so that the problem that the locking screw cannot be locked due to the fact that the secondary locking part is touched when the locking screw is adjusted can be solved.

Preferably, a retaining ring is arranged on the lower side of the secondary locking piece and fixedly connected to the locking cover; the retaining ring can ensure that the secondary locking piece cannot automatically fall out when not stressed, and can be extruded only when pressed.

Preferably, a through hole which is through up and down is formed in the nut, the locking screw penetrates through the through hole, and the inner diameter of the through hole is larger than the outer diameter of the locking screw; the structure can avoid the problem that the height of the ground base plate is changed due to the contact of the locking screw rod and the nut in the locking process.

Therefore, the utility model discloses following beneficial effect has: (1) after the ground base plate is installed, the height of the ground base plate can be adjusted through the screw cap and the screw rod, so that leveling can be performed quickly and conveniently; (2) after leveling, the load in the horizontal direction on the support platform can be shared through the elastic washer, so that the problem of nut looseness after long-time use is avoided; (3) the vertical load on the screw can be shared by locking the screw, so that the damage to the thread is relieved; (4) the nut can be locked through the secondary locking piece, so that the height change caused by the rotation of the nut is avoided; (5) the structure is compact.
