Problems solved by technology

[0002] In traditional construction, round steel with a diameter of 20mm is often used as the lifting ring. This part is embedded in the concrete and cannot be removed during demolition. Cut off, and in the construction of the rod-type cantilevered scaffolding, the screw cannot be used flexibly
Traditional building construction has a greater impact on construction efficiency and economic benefits
The existing lifting rings or tie rods need to pre-embed a part of the structure in the concrete. Not only is it easy to disassemble and assemble, so as to achieve the purpose of multiple use, but also a part of the structure will remain in the concrete, which is a waste of cost for the builder and is harmful to the The overall structure of concrete causes damage to a certain extent; therefore, there is an urgent need for an assembled screw assembly that can overcome the above problems

Embodiment 1

[0022] Example 1: See Figure 1 to Figure 5 , an assembled screw assembly in this embodiment includes a screw 2, a first threaded part 21 and a second threaded part 23 are respectively provided at both ends of the screw 2, and a useful thread is provided between the first threaded part 21 and the second threaded part 23 It is fixed on the support part 22 in the wall 1; it also includes a first fixing component adapted to the first threaded part 21 and a second fixing component adapted to the second threaded part 23, the first fixing component includes The first spacer 6 and the first nut 3 arranged on the part 22, the second fixing assembly includes the second spacer 4 and the lifting device arranged away from the support part 22, the first threaded part 21 and the second threaded part 23 The diameters are all smaller than the diameter of the support portion 22 . Pass the screw 2 through the pre-embedded hole, fix the screw 2 through the first fixing component and the second ...

Embodiment 2

[0023] Embodiment 2: The support part 22 of this embodiment is arranged obliquely with the wall 1, the side of the first spacer 6 close to the wall 1 is provided with a first inclined fixing surface that fits the wall 1, and the second spacer 4 is close to the wall 1 One side of the wall 1 is provided with a second inclined fixing surface attached to the wall 1 . The screw assembly is installed obliquely and uses high-friction pads, so the force-bearing form is reasonable; the lifting ring 5 and the tie rod 7 are made of high-strength steel, and the force-bearing performance is better than that of the traditional anchor ring. The lifting assembly of this embodiment includes a lifting ring 5 , and the lifting ring 5 includes an integral internal thread sleeve 52 and a fixing ring 51 , and the internal thread sleeve 52 is adapted to the second threaded part 23 . The depth of the internal thread of the internally threaded sleeve 52 in this embodiment is not less than the length o...

Abstract

The invention discloses a fabricated screw rod assembly which comprises a screw rod; the two ends of the screw rod are provided with a first thread part and a second thread part respectively; a supporting part used for being fixed in a wall is arranged between the first thread part and the second thread part; the screw rod assembly further comprises a first fixing assembly and a second fixing assembly; the first fixing assembly is matched with the first threaded part; the second fixing assembly is matched with the second threaded part; the first fixing assembly comprises a first cushion block and a first nut which are arranged away from the supporting part; the second fixing assembly comprises a second cushion block and a lifting device which are arranged away from the supporting part; and the diameters of the first thread part and the second thread part are smaller than the diameter of the supporting part. The screw rod penetrates through a pre-buried hole site, the screw rod is fixed through the first fixing assembly and the second fixing assembly at the two ends, and then a needed lifting device is installed, so that a lifting function can be achieved; and meanwhile, the fabricated screw rod assembly can be detached to other places to be repeatedly used after being used, and finally a reserved hole site is filled, so that the influence of the screw rod on a concrete beam can be completely eliminated.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an assembled screw assembly. Background technique [0002] In traditional construction, round steel with a diameter of 20mm is often used as the lifting ring. This part is embedded in the concrete and cannot be removed during demolition. Cut off, and in the construction of the rod-type cantilevered scaffolding, the screw cannot be used flexibly. Traditional building construction has a great impact on construction efficiency and economic benefits. The existing lifting rings or tie rods need to pre-embed a part of the structure in the concrete. Not only is it easy to disassemble and assemble, so as to achieve the purpose of multiple use, but also a part of the structure will remain in the concrete, which is a waste of cost for the builder and is harmful to the The overall structure of concrete causes damage to a certain extent; therefore, there is an urgent need for an assemb...
