The specific embodiment
A kind of reinforced concrete embedded ruggedized construction of the present utility model, clearer, clear and definite for making the purpose of this utility model, technical scheme and advantage, below the utility model is further described with reference to the accompanying drawing embodiment that develops simultaneously.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
A kind of reinforced concrete embedded ruggedized construction that the utility model embodiment provides as shown in Figure 1, comprises reinforced concrete structure body 140, and is arranged on the main reinforcement 130 in the reinforced concrete structure body 140.Important improvement part of the present utility model is: offer groove 141 on described reinforced concrete structure body 140, size that institute's groove 141 is offered and concrete number should be decided according to the need situation of reinforcing.As on the reinforced concrete structure rectangular beam, offering two grooves 141 in the present embodiment.
The reinforced concrete embedded ruggedized construction of the utility model embodiment, as shown in Figure 1, it comprises also and the adaptive aluminium alloy plate 200 of described groove 141 shapes that described aluminium alloy plate 200 is fixed in the groove 141 of described reinforced concrete structure body 140 reinforcing areas.As shown in Figure 1: described groove 141 is two, and the described aluminium alloy plate 200 that adapts with it also is two.
Preferably embodiment is provided with adhesive layer 120 at described aluminium alloy plate 200 external surfaces, and described aluminium alloy plate 200 is pasted with described groove 141 by described adhesive layer 120 and is connected.Described adhesive layer is the modified epoxy resin adhesive layer.Like this, described aluminium alloy plate 200 can be sticked in the groove 141 of described reinforced concrete structure body 140 securely.Like this, because the aluminum alloy high-strength low-quality, intensity and ductility and structural iron are close, and density only is 1/3 of steel.Therefore, use the aluminium alloys reinforced concrete structure, be expected under the situation that does not significantly increase dead load, improve the safety of structure, guarantee ductility preferably simultaneously.And described aluminium alloy plate 200 is reinforced in the groove 141 of described reinforced concrete structure body 140, made overall structure more firm.
Preferably, the material of described adhesive layer 120 adopts modified epoxy resin adhesive.And adhesive layer thickness is about 3mm.
Like this, reinforced concrete embedded ruggedized construction of the present utility model has adopted aluminium alloy plate to possess fabulous corrosion resistance and intensity and the plasticity close with steel, can solve the deficiency of existing reinforcement means preferably; Bearing capacity performance and endurance quality that it could repair and improve steel concrete, the safety that improved cost performance, improves structure guarantees ductility preferably simultaneously, and makes overall structure more firm.
Above-mentioned reinforced concrete embedded ruggedized construction when concrete construction, as shown in Figure 2, may further comprise the steps:
S301, in reinforced concrete structure body 140 reinforcing area positions, with adopt makita 4100NH in accordance with regulations size offer groove 141, two grooves 141 as shown in Figure 1, and remove dust in the described groove 141;
S302, the reinforcing area surface finish cleaning of reinforced concrete structure body is smooth; Promptly as Fig. 1 as showing, the groove 141 surface finish cleaning of described reinforced concrete structure body 140 reinforcing areas is smooth.
After groove 141 dry tack frees of S303, the reinforced concrete structure body reinforcing area cleared up of waiting to polish, the groove inner surface and the dust on the described aluminum alloy plate materials of described reinforced concrete structure body reinforcing area are cleaned with cleaning agent.
S304, employed cementing agent is stirred by instructions for use.
S305, preparation and the adaptive aluminium alloy plate of described groove 141 shapes spread upon described groove inner surface and aluminium alloy plate external surface with cementing agent, and described aluminium alloy plate are sticked in the groove of described reinforced concrete structure body reinforcing area.
Whether S306, inspection have the shortcoming part of not filling cementing agent, then will be short of part as required and pour into cementing agent again, and push, and the air of sneaking into sticking area is extruded, and unnecessary cementing agent is removed.
S307, with clamp or with the fixing reinforcing area surface of aluminium alloy plate and reinforced concrete structure body of braced structures, and suitably pressurization guarantees the reliability of bonding.
S308, after cementing agent sclerosis, body structure surface is cleared up once more, keep its surfacing.
Reinforced concrete embedded ruggedized construction provided by the utility model, owing to adopted in the reinforcing area groove of described reinforced concrete structure and be pasted with aluminium alloy plate, and aluminium alloy plate possesses fabulous corrosion resistance and intensity and the plasticity close with steel, can solve the deficiency of existing reinforcement means preferably; And described aluminium alloy plate 200 is reinforced in the groove 141 of described reinforced concrete structure body 140, made overall structure more firm; And the following advantage of tool:
(1), the high-strength low-quality of aluminium alloy plate, intensity and ductility and structural iron are close, density only is 1/3 of steel.Therefore, the utility model uses the aluminium alloy plate reinforced concrete structure, and the safety that can improve structure under the situation that does not significantly increase dead load guarantees ductility preferably simultaneously.
