Abstract
This invention relates to an antiseptic treatment method of the embedded parts, which comprises the following steps: a, reserving 1-10 steer bars in the configuration bit where needs the embedded parts, then connecting the embedded parts with the steer bars; b, setting concrete block in the structure surface where needs the embedded parts, wherein the concrete block has the same material with the structure; c, setting the embedded parts in the concrete block, the concrete layer between the concrete block layer and the embedded parts is 3-20cm. When uses, setting the embedded parts in the concrete block in the structure outer wall, wherein the size of the concrete can be decided by the size of the embedded parts, and the surface of the embedded parts apply the anticorrosion material. If the embedded parts are corrupt, it can strike out the concrete block and install the embedded parts again.
Description
Technical field:
The present invention relates to antiseptic technical field, specifically a kind of method for anticorrosion treatment that is used for built-in fitting.
Background technology:
Corrosion is quite serious to the harm and the destruction of municipal engineering under some particular surroundings, maritime works, hydraulic engineering, particularly having under the situation of set aside pre-embedded spare, some built-in fitting is in order to guarantee its intensity, need to be connected with the internal construction reinforcing bar, and this built-in fitting also becomes the passage of corrosion when finishing external equipment task is installed, the time slightly length may have influence on the internal construction reinforcing bar, and then influence the safety of structure, and built-in fitting also is difficult to change after corrosion takes place.The anti-corrosion measure of adopting at present mainly contains: a kind of is the mechanical isolation measure; promptly adopt certain material to be coated on material surface to be protected; make it to isolate to reach etch-proof purpose with the material of generation corrosion such as seawater, oxygen; but wherein the anticorrosive paint construction is simple; general easy to be aging, the time limit is about 10-20 usually.Another kind is the metal spraying partition method, generally comprise spray metal layer and seal coat, but cost is higher.
Summary of the invention:
The object of the present invention is to provide a kind of improved method for anticorrosion treatment that is used for built-in fitting, it can overcome, and anti-corrosion measure is aging easily in the prior art, built-in fitting corrodes the back influences the some shortcomings that are difficult to change after structure safety, the built-in fitting corrosion.
To achieve these goals, technical scheme of the present invention is: a kind of method for anticorrosion treatment that is used for built-in fitting, it is characterized in that: described method for anticorrosion treatment comprises the steps: a, reserves 1-10 root reinforcing bar at the structure position that needs built-in fitting, then built-in fitting is linked to each other with reinforcing bar; B, the place that need lay built-in fitting on the structure surface are provided with concrete block, and concrete adopts the concrete material identical with structure; C, built-in fitting is placed in the concrete block, the layer of concrete between concrete block top layer and the built-in fitting is 3-20cm.
The present invention is installed in built-in fitting in the concrete block of structure outer wall during use, and concrete size is decided by the size of built-in fitting, and the method for anticorrosive paint or metal spraying is adopted on the built-in fitting surface, reduces the corrosion of surrounding environment to built-in fitting.Even if external environment is extremely abominable, after built-in fitting corrodes, this concrete block can be struck down, the structure reinforcing bars that keeps structure, reinstall built-in fitting, so just avoided having influenced the situation of structure structure, also solved the very difficult difficulty of changing of built-in fitting in the past simultaneously because of the corrosion of built-in fitting.
Description of drawings:
Fig. 1 is the structural representation of one embodiment of the invention
Fig. 2 is the structural representation of further embodiment of this invention
Fig. 3 is the structural representation of an alternative embodiment of the invention
The specific embodiment:
The invention will be further described below in conjunction with drawings and Examples.
A kind of method for anticorrosion treatment that is used for built-in fitting of the present invention, its difference with the prior art is: described method for anticorrosion treatment comprises the steps: a, reserves 1-10 root reinforcing bar at the structure position that needs built-in fitting, then built-in fitting 1 is linked to each other with reinforcing bar; B, the place that need lay built-in fitting on the structure surface are provided with concrete block, and concrete adopts the concrete material identical with structure; C, built-in fitting is placed in the concrete block 2, the layer of concrete between concrete block top layer and the built-in fitting is 3-20cm.In concrete block is wrapped in built-in fitting and the reinforcing bar that links to each other with built-in fitting in the lump.Simultaneously the method by reinforcing bar welding or bolted splice is connected between built-in fitting and the reinforcing bar.Wherein the making of concrete and built-in fitting is prior art, has just repeated no more its manufacturing process here.
Embodiment 1
Pre-buried ground connection steel plate on the bridge pier of a bridge spanning the sea draws the ground connection steel plate outside reaching, and is used for bridge ground connection (as shown in Figure 1).Because maritime environment is abominable, pre-buried ground connection steel plate can have influence on bridge internal construction reinforcing bar with the long-term corrosion that draws the ground connection steel plate outward, jeopardize bridge security, in the enforcement, draw ground connection steel plate 3 outward and reserve 2 reinforcing bars in advance, by welding pre-buried ground connection steel plate is linked to each other with the reinforcing bar that draws the ground connection steel plate outward then, need the place of the pre-buried ground connection steel plate of placement to adopt concrete block of concrete for making of the same specification label with bridge pier on the bridge pier surface then, draw ground connection steel plate junction outside then pre-buried ground connection steel plate being reached and imbed together in the concrete block, the layer of concrete between concrete block top layer and the pre-buried ground connection steel plate is 10cm.From now on when be exposed to draw the ground connection steel plate outside airborne and be corroded after, can be with this concrete block knock-off, change one then and draw the ground connection steel plate outward, avoided influencing member, thereby influenced the structure of structure because of the corrosion of functor.
The ground connection pre-embedded steel slab is arranged on the bridge pier of a bridge spanning the sea, be used for bridge earthy (as shown in Figure 2).Because maritime environment is abominable, the corrosion of built-in fitting can have influence on bridge internal construction reinforcing bar, if directly built-in fitting is installed on the bridge pier, built-in fitting can't be changed from now on.Adopt now and do a concrete block at the very useful concrete of pier with the same label of bridge pier, in spray metal, built-in fitting surface coating, then built-in fitting and 2 exposed steel bars that stretch out bridge pier are weldingly connected by reinforcing bar, at last built-in fitting is installed in the concrete block, layer of concrete between concrete block top layer and the built-in fitting is 5cm, after built-in fitting is corroded, this concrete knock-off can be changed a built-in fitting from now on.
The pre-embedded steel slab (seeing for details shown in Figure 3) of built-in fitting is installed at bridge spanning the sea case beam inner water tube, cable bearer.Need be on beam pre-embedded steel slab, earlier about 1 reinforcing bar that reveals of steel plate and mounting bracket is linked to each other, coat anticorrosive paint at surface of steel plate then, with concrete the root of support 4 is used with the concrete of the same label of bridge at last and coated, layer of concrete between concrete block top layer and the pre-embedded steel slab is 8cm, plays good antisepsis, and easy construction is easily gone, reduce investment outlay, effect is better.
