Accompanying drawing explanation
Fig. 1 to Fig. 4 is the view of steel concrete steel pipe column construction method of the present invention.
Detailed description of the invention
For the benefit of to the understanding of structure of the present invention, be described below in conjunction with drawings and Examples.
Please refer to Fig. 1 to Fig. 4, the invention provides a kind of steel concrete steel pipe column construction method, include but not limited to the step of following order:
S1, as shown in Figure 1, erection column sole 20 on construction basis 1, construction basis 1 has pre-buried linkage section 30, and pre-buried linkage section 30 is arranged in heel slab 20 and stretches out construction basis 1;
S2, pre-buried linkage section 30 ties up connecting reinforcement cage 3;
S3, as shown in Figure 2, drawknot tension part 4 between reinforcing cage 3 and construction basis 1, makes the reinforcing cage 3 of colligation be in vertical state;
S4, as shown in Figure 3, after the colligation completing reinforcing cage 3, lifting steel pipe column 5, from top to bottom entangles reinforcing cage 3 and release tension part 4 thereupon by steel pipe column 5;
S5, as shown in Figure 4, after the lifting completing steel pipe column 5, is installed on steel pipe column 5 on heel slab 20.
As shown in Figure 1, stone bolt 21 is provided, the mounting method that stone bolt 21 is general is two kinds, the first mounting method is an implantation, during placing of concrete construction basic 1, stone bolt 21 is imbedded, now in step S1, on construction basis 1, erection column sole 20 specifically comprises: pre-embedded anchoring bolts 21 on construction basis 1, and wears heel slab 20 on stone bolt 21; The second mounting method of stone bolt 21 is Reserved Hole Method, now in step S1, on construction basis 1, erection column sole 20 specifically comprises: reserving hole on construction basis 1, described reserving hole is cleaned up, stone bolt 21 is put into described reserving hole, water with than construction basis 1 higher leveled ungauged regions pea gravel concreten, make firm by ramming closely knit, and wear heel slab 20 on stone bolt 21.It should be noted that, when using the first mounting method mounting foot bolt 21, step S1 should prior to performing before step S2 to step S4, and when using the second mounting method mounting foot bolt 21, step S1 can perform after step S2 and step S3 again.
Continue with reference to figure 1, in step s 2, start assembling reinforcement cage 3, as shown in Figure 1, reinforcing cage 3 part is embedded in construction basis 1 in advance, namely reinforcing cage 3 comprises the pre-buried linkage section 30 be embedded in advance in construction basis 1, during assembling reinforcement cage 3, vertical muscle is connected with joint bar, pre-buried linkage section 30 from bottom to top ties up connecting reinforcement cage 3, wherein, heel slab 20 is the intersections being located in reinforcing cage 3 and construction basis 1.
Next, please refer to Fig. 2, in step s3, provide a tension part 4, one end drawknot of tension part 4 is on the reinforcing cage 3 of colligation, and the other end of tension part 4 is anchored on construction basis 1.Wherein, tension part 4 can be oblique rollering steel silk rope, can the pre-buried U-shaped round steel for connecting steel wire ropes 4 on construction basis 1.Drawknot tension part 4 in assembling reinforcement cage 3 process, by one end drawknot of tension part 4 on the reinforcing cage 3 of colligation, the other end of tension part 4 is anchored on construction basis 1, specifically comprise: whenever reinforcing cage 3 upwards colligation one section of colligation distance time, by one end drawknot of wire rope 4 on reinforcing cage 3 top of colligation, the U-shaped round steel of other end oblique pull on construction basis 1 of wire rope 4.Concrete, colligation distance can be 3m, every 3m, wire rope 4 is carried out stretching and fixes, ensure reinforcing cage 3 verticality.Certainly, also just wire rope 4 can be carried out stretching every 2m or 3.5m and fix, the application is not specifically limited colligation distance.In practice, general reinforcing cage 4 is rectangle, comprise four limits, now step S3 can be: whenever reinforcing cage 3 upwards colligation one section of colligation distance time, four wire rope 4 are provided, corresponding drawknot is distinguished on four limits on reinforcing cage 3 top of colligation in one end of four wire rope 4, the U-shaped round steel of other end oblique pull on construction basis 1 of four wire rope 4.Consider that reinforcing cage 4 on construction ground also can for making circle, now, also can every certain altitude, four wire rope 4 are provided, wherein, drawknot is on the reinforcing cage 3 of colligation at equal intervals for one end of four wire rope 4, and four wire rope 4 are divided into two groups, often organize two wire rope 4, two symmetrical drawknots of wire rope 4 often in group are on the reinforcing cage 3 of colligation.
Next, please refer to Fig. 3, in step s 4 which, after reinforcing cage 3 colligation completes, lifting steel pipe column 5, makes steel pipe column 5 from top to bottom entangle reinforcing cage 3, and release tension part 4 thereupon.Steel pipe column 5 is provided with peg 6, when reinforcing cage 3 verticality that colligation completes is inadequate, during lifting steel pipe column 5, be easy to cause the peg 6 on steel pipe column 5 to be stuck on reinforcing cage 3, be unfavorable for the lifting of steel pipe column 5, just because of every certain altitude, wire rope 4 carried out stretching and fix, thus ensure that reinforcing cage 3 verticality, ensure that steel pipe column 5 can lift smoothly.When lifting steel pipe column 5, first release is positioned at the wire rope 4 at reinforcing cage 3 top, along with steel pipe column 5 is toward declining, when steel pipe column 5 declines one section of dropping distance, by from steel pipe column 5 nearest wire rope 4 first discharge, discharge wire rope 4 from top to down along with the decline of steel pipe column 5 thereupon, until steel pipe column 5 falls within mounting platform 2, dropping distance can be equal to colligation distance, also can be different from colligation distance, to this, the application is not specifically limited.
Next, please refer to Fig. 4, in step s 5, steel pipe column 5 falls within after on heel slab 20, is installed on by steel pipe column 5 on heel slab 20, and steel pipe column 5 can be welded on heel slab 20, also can be bolted on heel slab 20 by otic placode, to this, the application be not specifically limited.
Beneficial effect of the present invention is:
By coordinating the colligation of reinforcing cage and the lifting of steel pipe column, and temperature pier being carried out to highly higher reinforcing cage, ensure that its verticality, ensure that the smooth lifting of steel pipe column simultaneously, solved the difficult problem that superelevation small bore steel concrete steel pipe is difficult to construct.
