Description
Technical field
The present invention relates to Thermal Power Plant Construction technical fields, use large scale arc built-in fitting more particularly to silo outer wall is fixed
Bracing means and application method.
Background technique
Built-in fitting is usually placed in the surface of concrete structure, for the installation of Equipment Foundations, support of pipelines etc., should with it is mixed
Solidifying soil flush, position are accurate.The conventional installation methods of built-in fitting are: the aperture in template and built-in fitting, by drawing spiral shell
Bolt is fixed on built-in fitting on the inside of template, to realize that the installation of built-in fitting is fixed.
And for some Super High industrial buildings, in order to enable template to be repeatedly used in turn, until Practical Completion, often
Using steel form, but often there is part built-in fitting in these Super High industrial building surfaces, and these built-in fittings
Size is bigger, and built-in fitting size can reach 10500mm × 300mm × 14mm standard and it is pre- to be therefore easy to appear large scale
Embedded part and steel form are difficult to fixed problem in the case where exempting from aperture, and a kind of solution is in large scale built-in fitting and punching block
On plate after aperture, realizes and effectively fix, but in the place of not built-in fitting, the tapping of template be easy to cause concrete to leak
Slurry.
Therefore, although on built-in fitting and steel form aperture realization be fixedly secured by way of solve fixation problem,
New problem caused by but, and be not suitable for, it needs to develop one kind when steel form exempts from aperture, can guarantee that large scale is pre-
The bracing means of embedded part fixation.
Summary of the invention
For above situation, for the defect for overcoming the prior art, the present invention provides silo outer wall fixed large scale arc
The bracing means and application method of built-in fitting solve the problems, such as that large scale built-in fitting is not fixed firmly in the case where not punching.
Its technical solution is the fixed bracing means for using large scale arc built-in fitting of silo outer wall, including is used in steel form
Multiple reinforcing bars and multiple dowels between built-in fitting, the steel form include inner arc steel form and outer arc steel form, described big
The built-in fitting of size is extended in the length of common built-in fitting, and width is basically unchanged, and radian is suppressed by veneer reeling machine
At；The steel form is the inner arc template and outer arc template of silo barrel, and the length of the steel form is less than described large-sized
The length of built-in fitting, for the built-in fitting between steel form and close to outer arc steel form, each dowel includes one end mantle fiber
Connection dowel and the not support dowel of mantle fiber, each described dowel one end and built-in fitting intrados is fixed by welding connects
It connects, the non-mantle fiber in one end that each connection dowel is fixedly connected with built-in fitting, each end reinforced mantle fiber simultaneously passes through positive and negative silk
Sleeve is used cooperatively with dowel is connect, and is provided through the pvc pipe of reinforcing bar outside the positive and negative silk braid cylinder, the pvc pipe internal diameter with
The outer diameter of the positive and negative silk braid cylinder is consistent, is formed and is reinforced after the connection dowel, reinforcing bar, positive and negative silk braid cylinder and pvc pipe socket
Body unit, each reinforcing body unit extend from outer arc steel form direction to inner arc steel form, and each reinforcing body unit is separate
The pvc pipe of one end end of outer arc steel form is connect by rubber plug with inner arc steel form.
Further, each dowel is fixed by welding with built-in fitting inner arc side, and each dowel is pre-buried
On part in the way of vertical spacing 90mm and horizontal direction spacing 150mm array arrangement, it is each it is described connection dowel between water
Flat spacing is 300mm.
Further, each pvc pipe reinforced on body unit is located at positive and negative silk braid close to one end end plane of dowel
One end of cylinder middle part, one end end of the pvc pipe far from dowel and the non-mantle fiber of reinforcing bar maintains an equal level.
Further, dowel mantle fiber end matches with positive and negative silk braid cylinder and connect, the mantle fiber end of the reinforcing bar with it is described
Positive and negative silk braid cylinder match connection.
Further, the rubber plug is with reeded rotary table, and the groove diameter and pvc pipe end diameter are kept
Unanimously, it is mutually matched, the plug one side not with groove of comparing is adjacent to inner arc steel form.
The application method of the fixed bracing means with large scale arc built-in fitting of silo outer wall:
S1. shift to an earlier date pre-buried steel form, and set the position at built-in fitting outer arc steel form, in connection dowel and end reinforced set
Silk, herein operation are to use the precondition of bracing means；
S2. dowel is fixed on built-in fitting, and by positive and negative silk sleeve connection reinforcing bar with connect dowel, pvc pipe is covered in steel
Muscle connects formation reinforcing body unit on the supporter to be formed with dowel is connect；
S3., built-in fitting with non-mantle fiber dowel and reinforcing body unit is lifted up into the predeterminated position of pre-buried punching block plate；
S4. being connected and fixed between pvc pipe and inner arc steel form is realized using rubber plug；
S5. rotating the positive and negative silk braid cylinder reinforced on body unit on built-in fitting simultaneously increases the protruded length for connecting dowel and reinforcing bar
Add, connects dowel and reinforcing bar during length increases, end reinforced increasingly closer with the distance between inner arc template, gap
Become smaller, until rubber plug and built-in fitting are held out against with inner arc steel form and outer arc steel form respectively, until built-in fitting no longer loosen,
The large scale arc built-in fitting, is effectively fixed on the design position on the inside of outer steel mould plate, even if pouring in concrete by sliding
Also it can guarantee that the position of the large scale arc built-in fitting does not shift when building and vibrating, realize and exempt from aperture in template
In the case of large scale arc built-in fitting fixation；
S6. casting concrete and vibration compacting；
S7. after concrete crushing strength reaches demoulding requirement, inner arc steel form and outer arc steel form is removed, rubber plug is pulled out
And reinforcing bar of dismantling is rotated, after outer arc steel form is removed, the large scale arc built-in fitting surface is flushed with concrete surface, is protected
The finishing effect of built-in fitting and concrete surface is demonstrate,proved；
S8. finally hole left after dismounting rubber plug and reinforcing bar is blocked with cement mortar, so that dowel
Protective layer thickness not exposed and that dowel has been effectively ensured.
The solution have the advantages that not punching between built-in fitting and steel form, turnover rate is high, avoids concrete in template
The problem of tapping spillage, realizes the fixation of built-in fitting by bracing means before dismantling steel form, mixed by pouring later
Solidifying soil, even if also can guarantee the fixation of built-in fitting, and large scale arc built-in fitting surface and concrete table after steel form dismounting
Face flushes, and ensure that the finishing effect of built-in fitting and concrete surface, and install convenient guarantees that the position of built-in fitting is precisely and fixed
Securely, the reinforcing bar after dismounting and rubber plug can reuse, economic and environment-friendly.
