Description
Technical field
The invention belongs to the technical field of building, relate in particular to the job practices of the two limb pier studs of the extra small spacing of a kind of bridge construction.
Background technology
When the spacing extra small (less than 0.2m) between two limb tower piers; The space is extremely narrow and small between the tower pier; If with common template; Installation, adjustment, dismounting to adjacent towers limb template bring very big difficulty, and in a single day pier shaft concrete defect occurs and can't modify processing, admittedly outward appearance must be good after requiring concrete formation.
Summary of the invention
The technical problem that the present invention will solve provides the job practices of the two limb pier studs of the extra small spacing of a kind of bridge construction, can guarantee that two limb pier studs construct simultaneously, the spacing precision is controlled better.
In order to solve the problems of the technologies described above, the present invention provides following technical scheme: the job practices of the two limb pier studs of the extra small spacing of a kind of bridge construction may further comprise the steps:
A, the two limb pier stud integral mold plates of the extra small spacing of making bridge construction and body of the tower template, wherein, the two limb pier stud integral mold plates of the extra small spacing of bridge construction comprise gad and two external molds;
B, two limb pier stud integral mold plates of the extra small spacing of bridge construction and body of the tower template are transported to the job site; By survey crew the creeping formwork template is precisely located before installing; Two external molds of the two limb pier stud integral mold plates of the extra small spacing of bridge construction are provided with dorsad during installation; Form the wedge groove between two external molds, the work plane of two external molds is towards pier shaft to be built;
C, the two limb pier stud integral mold plates of the extra small spacing of bridge construction are located with alignment pin, connect with bolt;
Connect with pull bar between two limb pier stud integral mold plates of d, the extra small spacing of two bridge constructions and the body of the tower template and be fixed on the internal mold, tie rod hole is used the sponge shutoff;
Adopt the gad wedging to carry out the spacing fine setting and fix between the two limb pier stud integral mold plates of e, the extra small spacing of two bridge constructions are suitable for reading;
F, accomplish two limb pier stud integral mold plates of the extra small spacing of bridge construction and body of the tower template fixing after, concreting;
G, treat that concrete reaches intensity after, remove two limb pier stud integral mold plates of the extra small spacing of bridge construction and body of the tower template, the brushing release agent;
H, the two limb pier stud integral mold plates of the extra small spacing of lifting bridge construction and body of the tower template drop into next sections and use.
Compared with prior art, the invention has the advantages that: 1, the work plane of two external molds embeds gad towards pier shaft to be built between two external molds, to fill up the extra small spacing between two limb pier studs, is applicable to the extremely narrow and small situation in space between the tower pier; 2, extra small spacing body of the tower template does not produce distortion because of dismantling operation is improper; 3, concrete surface is not by scratch, and surface quality is good; 4, build sections construction under treated equal can the input of rear pattern plate at every turn.
Further, the method for said step g stripping does, unclamps gad earlier, unclamps alignment pin again, unclamps Screw arbor with nut at both-ends then, the bolt of dismantling at last.
Description of drawings
Below in conjunction with accompanying drawing and embodiment technical scheme of the present invention is further specified:
Fig. 1 is the structural representation of the two a kind of embodiment of limb pier stud integral mold plate of the extra small spacing of bridge construction among the present invention.
The specific embodiment
As shown in Figure 1, the job practices of the two limb pier studs of the extra small spacing of a kind of bridge construction of the present invention may further comprise the steps:
A, the two limb pier stud integral mold plates of the extra small spacing of making bridge construction and body of the tower template, wherein, the two limb pier stud integral mold plates of the extra small spacing of bridge construction comprise gad and two external molds;
B, two limb pier stud integral mold plates of the extra small spacing of bridge construction and body of the tower template are transported to the job site; By survey crew the creeping formwork template is precisely located before installing; Two external molds of the two limb pier stud integral mold plates of the extra small spacing of bridge construction are provided with dorsad during installation; Form the wedge groove between two external molds, the work plane of two external molds is towards pier shaft to be built;
C, when every sections template is installed, the creeping formwork template is precisely located, guarantee that creeping formwork template position error less than 3mm, is detected the template alignment error together with quality inspection, survey crew by engineering department in the template installation process in real time by survey crew;
All use the round steel suspension ring of design to carry out when d, formwork hoisting;
Join brill after e, the two limb pier stud integral mold plates of the extra small spacing of bridge construction and the creeping formwork Template Location aperture examination assembly unit, locate with conical dowel pin during installation; Embed the thick double-sided tape of 1mm between two limb pier stud integral mold plates of the extra small spacing of bridge construction and the creeping formwork template and seal, carry out template with the M16 bolt and connect;
Connect with Φ 16 pull bars between the two limb pier stud integral mold plates of f, the extra small spacing of bridge construction and be fixed on the two tower limb internal molds, pull bar adopts Φ 20 plastic conduits to make sleeve pipe, and the extra small spacing of bridge construction pair limb pier stud integral mold plate collar aperture are carried out reliable shutoff with sponge;
