Description
Technical Field
The utility model relates to a stair bench construction technical field specifically is exempt from to cut recoverable inner tower steel pipe collet.
Background
In cast-in-place reinforced concrete structures, stairways and decks are often cast with the roof of the floor.
When the support frame is arranged in the construction site, the inner frame steel pipe of a certain section of floor slab needs to be supported on a template of the stair platform plate to be poured, and therefore, the inner frame steel pipe can be poured into the stair platform plate together when concrete is poured.
When the inner frame and the template are dismantled in the later stage, the steel pipe poured with the concrete cannot be taken out and only a cutting mode can be adopted. Doing so wastes time and labor, and has the quality problems of leakage, floor slab cracks and the like.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a exempt from to cut recoverable inner tower steel pipe collet to solve the problem that proposes in the above-mentioned background art.
The technical scheme of the utility model is that: exempt from to cut recoverable inner tower steel pipe collet, include reinforcing bar one, reinforcing bar two and treat to water the stair platform board, still include:
the steel bars are arranged in two, the two steel bars are L-shaped, and the two steel bars are welded in three phases;
the sleeve is arranged at the top end of one of the third steel bars, and the inner wall of the sleeve is also provided with the first steel bar;
the two second steel bars are fixedly connected with the first steel bar;
the inner frame steel pipe is arranged at the top end of the first steel bar;
and the third reinforcing steel bar and the sleeve are arranged inside the stair platform plate to be poured.
Preferably, the third reinforcing steel bar and the sleeve are arranged inside the stair platform plate to be poured in a pre-buried mode.
Preferably, marble cushion blocks are padded under the three reinforcing steel bars.
Preferably, the two second reinforcing steel bars are connected with the first reinforcing steel bar through welding.
The utility model discloses an improve and provide here and exempt from to cut recoverable inner tower steel pipe collet, compare with prior art, have following improvement and advantage:
through making processing reinforcing bar three in advance, reinforcing bar three is formed by the welding preparation of both ends L shape reinforcing bar, then three welded connection of two reinforcing bars, half with sleeve car silk installation at last, realize sleeve and the connection of reinforcing bar three, when ligature landing slab reinforcing bar, pre-buried reinforcing bar three and sleeve in advance, and fill up the marble cushion under reinforcing bar three, pass through spot welding with the slab reinforcing bar three and be connected, control sleeve elevation is level mutually with the face of pouring of waiting to pour the stair platform board, when setting up the inner frame structure, twist into telescopic upper portion with the bottom of reinforcing bar one earlier, then install the inner frame steel pipe, concreting, when demolising the inner frame steel pipe, only need to twist out reinforcing bar one from the sleeve, can reuse, do so promptly labour saving and time saving, can also avoid taking place quality problems such as seepage, floor crack.

Detailed Description
The present invention will be described in detail below, and it is apparent that the technical solutions in the embodiments of the present invention are described clearly and completely. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model discloses an improve and provide here and exempt from to cut recoverable inner tower steel pipe collet, the technical scheme of the utility model is:
as shown in fig. 1-2, exempt from to cut recoverable inner tower steel pipe collet, including reinforcing bar 1, reinforcing bar two 2 and treat to water building stair platform board 7, still include:
the number of the steel bars III 3 is two, the two steel bars III 3 are both L-shaped, the two steel bars III 3 are welded, and the two steel bars III 3 are arranged in a poor welding mode, so that the steel bars III can be stably fixed in the stair platform plate 7 to be poured;
the sleeve 4 is arranged at the top end of one of the steel bars III 3, the inner wall of the sleeve 4 is also provided with a steel bar I1, the inner wall of the sleeve 4 is provided with a turning wire, and the steel bar III 3 and the steel bar I1 can be connected with the sleeve 4 through the turning wire;
the two steel bars 2 are fixedly connected with the steel bar 1;
the inner frame steel pipe 5 is arranged at the top end of the first steel bar 1;
the three reinforcing steel bars 3 and the sleeve 4 are arranged inside the stair platform plate 7 to be poured.
Further, three 3 reinforcing bars and sleeve 4 all set up in the inside of waiting to water stair platform board 7 through pre-buried mode, and this kind of setting mode makes three 3 reinforcing bars, sleeve 4 and wait to water stair platform 7 structure as an organic whole.
Further, a marble cushion block 6 is padded under the steel bars 3.
Furthermore, the two steel bars 2 are connected with the steel bar 1 through welding.
