Description

Template reinforcing and opposite-pulling device for wall of cyclone well barrel

Technical Field

The utility model belongs to the technical field of the metallurgical construction and specifically relates to a whirl wellbore wall template is consolidated and is split device.

Background

The cyclone well is indispensable in a public auxiliary system for steel rolling and steel making, almost all is a circular reinforced concrete structure, has a large diameter (generally 18-35 meters), has a thick cylinder wall (generally 1-2 meters), is buried deeply (generally 20-35 meters), and belongs to key points and difficulties in construction. Common construction methods include major excavation, reverse construction method, open caisson and the like according to soil conditions, underground water level and peripheral working conditions. In the reverse construction method, the foundation pit support pile is usually a concrete cast-in-place pile. The barrel wall is constructed in a segmented mode from top to bottom, and the formwork is reinforced by adopting a counter-pulling screw rod as the wall body. Because the side wall of whirl well inner side section of thick bamboo can only one-way template seal, hug closely that the strut pile side can't normally set up the fixed point of split screw, generally adopt following concentrated mode: firstly, pre-burying iron parts on the support piles and then welding anchor bars, secondly, planting bars, and thirdly, removing a protective layer and welding main bars of the support piles. The main reinforcement is directly welded with the main reinforcement of the support pile, so that the main reinforcement is easily damaged, the welding process is complicated, and the construction efficiency is low; the bar planting mode is the same as the complex process, and the quality is not easy to ensure; the cost is higher when the embedded part is arranged.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a whirl well barrel wall template reinforcement is to drawing device that simple structure, effect are showing.

The utility model adopts the following technical scheme:

the utility model provides a whirl well barrel wall template reinforcing is to drawing device, includes the counter-pull rod, a fender pile, template and fossil fragments, and L type structure is buckled into to the counter-pull rod, and the one end of buckling of counter-pull rod is connected with a fender pile, and the other end is fixed with the fossil fragments in the template outside.

Compared with the prior art, the utility model discloses a show the effect and be:

the utility model has the advantages of simple structure, it is faster to the speed of pull rod bar planting, welding construction, and the efficiency of construction is higher, and direct and a fender pile founds muscle formation closure to the pull rod moreover, has improved construction quality.

Further, the utility model discloses a preferred scheme is:

a sleeve is arranged at the end part of the bent end of the opposite pull rod.

The bent end of the opposite pull rod is connected with the stud of the support pile.

The one end that the opposite pull rod is close to the template is provided with the external screw thread structure, and the fossil fragments outside is provided with the nut, and the opposite pull rod makes opposite pull rod and fossil fragments fixed through cooperating with the nut.

Detailed Description

The invention is further described with reference to the following figures and specific embodiments.

The utility model provides a whirl wellbore wall template reinforcement is to drawing device, includes counter-pull rod 6, fender pile 1, template 3 and fossil fragments 5, buckles 90 into L type structure to the one end of counter-pull rod 6, and the length of buckling is about 100mm, as shown in fig. 2, the A end is for buckling one end, one section sleeve pipe 7 of tip suit of A end, and the A end tip passes the 9 backs of fender pile grudging post, then buckles the A end once more through sleeve pipe 7, makes A end formation closed loop configuration, and the A end hoop is on a fender pile grudging post 9 this moment.

The other end of the opposite pull rod 6 is processed with an external thread structure with a certain length, as shown in fig. 2, one end of the external thread structure is a B end, and the B end penetrates through the template 3 and the keel 5 and is locked with the dovetail clamp 4 on the outer side of the keel 5 through the nut 8.

A swirl shaft wall template reinforcing and opposite-pulling construction method comprises the following steps:

1) removing the protective layer: according to the construction scheme of the template 3, the distance between adjacent pairs of pull rods 6 is designed and determined according to the scheme, protective layers are chiseled at the opposite positions of the surfaces of the corresponding support piles 1, and support pile vertical ribs 9 are exposed on each section of support pile 1 at equal intervals.

2) Manufacturing the counter pull rod 6: calculating the total length of the counter-pull rod 6, taking one counter-pull rod 6, bending one end of the counter-pull rod 6 by about 90 degrees, wherein the bent part is about 100mm long, and processing a thread structure with a certain length on the other end of the counter-pull rod 6.

3) And (3) binding steel bars on the cylinder wall 2: and (4) binding steel bars on the wall 2 of the cyclone well according to a construction design drawing.

4) Installing the counter pull rod 6: one bent end of the counter-pull rod 6 penetrates through the back of the support pile stud 9, and then the bent end is bent again by the sleeve 7, so that the end forms a closed annular structure around the support pile stud 9, namely the counter-pull rod 6 is connected with the support pile stud 9.

5) Sealing the mold and reinforcing: the template 3 is sealed to the whirl well inboard, will wear out template 3 and fossil fragments 5 to pull rod 6, screws up with forked tail card 4 cooperation nut 8 and pins.

6) Pouring concrete: and performing subsequent concrete pouring after the acceptance is qualified.

The inboard closed template 3 of whirl well because the thickness of template 3 is certain, increases in the outside of template 3 and is used for reinforced (rfd) fossil fragments 5, consequently will wear out template 3 and fossil fragments 5 to the pull rod, screws up with forked tail card 4 cooperation nut 8 and pins, and back of the body stupefied 10 can adopt double twisted steel, and fossil fragments 5 can adopt steel pipe or flitch.

The above is only the concrete implementation manner of the present invention, but the protection of the present invention is not limited to this, and all the equivalent changes or replacements proposed to the technical features of the present technical solution, which can be considered by those skilled in the art, are covered within the protection scope of the present invention.
