Mistake arrangement, the setting of steel wire 15 so that concrete 13 be not easy it is loose, collapse, substantially increase the intensity and anti-seismic performance of column.
It is arranged on steel reinforcement cage 11 it should be noted that steel wire 15 can first pass through supporting element in advance.
The concrete steel structural upright structural strength of present embodiment is good, and anti-seismic performance is good, concrete 13 be not easy it is loose,
It collapses, centre is filled using steel pipe 12, and the inside of steel pipe 12 does not need fill concrete 13, greatly reduces making for concrete 13
Dosage has saved cost, the weight of the column also mitigated, and the inside of steel pipe 12 can also be used to wear cable etc., thus
Cable is avoided to be exposed to external destroyed.
Embodiment 3
Embodiment of the present invention three provides a kind of production method of concrete steel structural upright, comprising the following steps:
Frock making step: mounting hole, the height gauge of mounting hole spacing from the ground are first opened up on 13 wall of armored concrete
Very little is 500-1200mm, and different height can be set according to different users, and one end of support rod is implanted into mounting hole simultaneously
Fixed, the other end of support rod is hanging.
It should be noted that support rod can also be fixed on other pedestals, for example, can first be arranged on the ground mostly with vertical
Column, more root posts are located along the same line, and then support rod is arranged on column, and a lateral edge of the separate support rod of column is vertical
Scale can be set in the arragement direction of column.
The quantity of support rod is at least two, in present embodiment, and the quantity of support rod is three, and three support rods are side by side
It is arranged and between same level height, adjacent two support rods there are certain spacing, this spacing is set as needed.When
So, the quantity of support rod may be three or more.
It portrays mark line step: portraying mark line on wall with marking pen, mark line is set along the arragement direction of support rod
There is a plurality of, the level height of the mark line and level height of support rod is essentially identical or the level height of mark line is slightly above
The level height of support rod, the spacing between adjacent two mark lines are 160mm, 180mm or 200mm.
First time stud 111 places step: two studs 111 being placed on the upside of support rod and pass through they sup-port
Firmly, stud 111 is arranged side by side along the axial direction of support rod and the both ends of two studs 111 are substantially flush.
In order to guarantee that the stud 111 for the upside for being placed on support rod will not slide, limit can be set on support rod
Position part, locating part can fix stud 111, so that the distance between two studs 111 of the upside of support rod
It will not change.
Stirrup 112 wears step: multiple stirrups 112 is sheathed on stud 111 from one end of stud 111 and/or both ends,
Mobile stirrup 112 to be equipped with a stirrup 112 at the corresponding position of each mark line.Certainly, two neighboring stirrup
The distance between 112 also can be adjusted according to the needs.
Second of stud 111 wears step: two studs 111 are penetrated to the lower section in stirrup 112 and being located at support rod again
And it is supported by stirrup 112, the stud positioned at the both ends and the upside for being located at support rod of the stud 111 of the lower section of support rod
111 both ends are substantially flush.
112 fixing step of stirrup: stirrup 112 is fixedly connected with stud 111.In the portion that stirrup 112 is contacted with stud 111
Stirrup 112 is fixed on stud 111 by position using binding piece, and binding piece can be solid using binding piece using tied silk or clip etc.
The mode for determining stirrup 112 is convenient for disassembly and assembly, work efficiency is high.Certainly, it can also connect with welding, weld between stud 111 and stirrup 112
Connect firm and reliable connection.
Whole stirrups 112 complete the production of steel reinforcement cage 11 after fixing.
Steel pipe 12 wears step: steel pipe 12 is passed through into stirrup 112, the both ends of steel pipe 12 are flushed with the both ends of stud 111,
Steel pipe 12 is supported in steel reinforcement cage 11 using connector 14.
Concrete 13 pours step: concrete 13 being poured to the outside for being filled in steel pipe 12, and guarantees concrete 13 by reinforcing bar
Cage 11 all wraps.
It should be noted that concrete 13 pours before step after steel pipe 12 wears step, it can be on steel reinforcement cage 11
Interlaced arrangement steel wire 15.
The production method for the concrete steel structural upright that present embodiment provides, easy to operate, producing efficiency is high, produces
Good product quality, manufacturing cost is low, have preferable marketing application value.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
