[0002] In old reservoirs, reinforced concrete supporting corbels are often used to provide support for the upper structure. The interior of the reservoir is in an environment of long-term chloride ion erosion, which easily causes cracks in the corbels of the reservoir. In the cross area of longitudinal and transverse deformation joints, the column corbels are damaged more seriously. Due to the high importance of the reservoir, which is responsible for the domestic water use of residents in a large surrounding area, in order to enhance the ability of the reservoir to resist the influence of construction and ensure the sustainable operation and use of the reservoir, its structural reinforcement is particularly important.

DETAILED DESCRIPTION

[0022] The following further elaborates on a support bracket reinforcement structure provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. In combination with the following description, the advantages and features of the present utility model will be clearer. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model.

[0023] Combined with Figure 1 and Figure 2 As shown, a support bracket reinforcement structure provided in this embodiment includes an original support bracket 1, anchor bolts 2, an outer steel plate 3, newly added bracket steel bars 4, newly added bracket stirrups 5, a grouting material coating layer 6, and a waterproof coating layer 7.

[0024] Among them, the original support bracket 1 includes original support bracket longitudinal steel bars 11, original support bracket bent steel bars 12, original support bracket stirrups 13, and original support bracket concrete 15. The original support bracket longitudinal steel bars, original support bracket bent steel bars, and original support bracket stirrups are all represented by dashed lines. Figure 1 The original support bracket tie bars 14 are also shown in the figure. The tie bars tie the original support bracket bent steel bars, and the tie bars are also represented by dashed lines. The damaged concrete on the surface of the original support bracket has been removed, so that a part of the original support bracket bent steel bars and original support bracket stirrups are exposed. The side view of the support part of the original support bracket 1 is a right trapezoid.

[0025] The outer steel plate 3 is fixed by the anchor bolts 2, and the anchor bolts 2 can be self-cutting screws. The outer steel plate includes a steel plate one 31, a steel plate two 32, and a steel plate three 33. The steel plate one 31 is a C-shaped steel plate, formed by welding three steel plates. The steel plate one is used to cover the support part of the original support bracket, and the height of the steel plate one is greater than or equal to the height of the support part of the support bracket, that is, the height of the steel plate one is greater than or equal to the length of the longer bottom side of the right trapezoid of the support part of the support bracket. The steel plate two 32 and the steel plate three 33 are rectangular steel plates. The steel plate two is horizontally arranged and welded and fixed to the bottom surface of the steel plate one. The steel plate three is vertically arranged. The steel plate three is fixed below the support part of the original support bracket by anchor bolts and welded and fixed to the steel plate two at the top.

[0026] Combined with Figures 1 to 3 As shown, the newly added bracket steel bars 4 are bent steel bars, arranged outside the outer steel plate, including an upper section steel bar and a lower section steel bar integrally arranged. The upper section steel bar is vertically arranged and welded and fixed to the outer wall of the steel plate one 31. An obtuse angle is formed between the upper section steel bar and the lower section steel bar. The bottom of the lower section steel bar is welded and fixed to the original support bracket longitudinal steel bars. For example, as Figure 3 shown, the bottom of the lower section steel bar is welded to the exposed original support bracket longitudinal steel bars 11 through short steel bars 8. The newly added bracket stirrups 5 are C-shaped, fixedly connected to the newly added bracket steel bars 4, and the ends are implanted into the concrete of the original support bracket and welded and fixed to the original support bracket longitudinal steel bars.

[0027] It should be noted that when constructing anchor rods, first position them on the concrete, use an electric hammer sleeve to drill holes, the hole diameter is determined according to the self-cutting screw model, use a manual pump or pneumatic pump to clean the hole, and the hole must be cleaned; place the anchor nuts and gaskets, tighten the accessories, and make the bottom of the screw flush with the bottom of the vertebral body; put the anchor into the hole through the fixed object, and use a hammer to push the self-cutting anchor rod into the hole until the gasket and nut are close to the surface of the substrate; use a torque wrench to tighten the bolts and nuts to the installation torque to complete the installation.

[0028] The grouting material coating layer 6 covers the steel plate 1, steel plate 2, steel plate 3, the newly added corbel steel bars and the newly added corbel stirrups, and the waterproof coating layer 7 is set on the surface of the grouting material coating layer 6. In the construction of the grouting material coating layer, a template is first set. The template adopts the side-wrapped bottom support method to facilitate the removal of the side template for turnover. The spacing between the template and the newly added corbel steel bars and the newly added corbel stirrups meets the requirements of the protective layer thickness, and self-compacting grouting material is used for pouring. After the grouting material is cured and finally set, use a hard bristle brush or other brushing tools to evenly apply the mixed penetrating crystallization waterproof coating on the base surface. The brushing direction should be consistent and uniform without accumulation, and the coating amount is 1.0-1.5 kg / square meter. After the first layer is dry, the second layer is brushed. Before brushing the second layer, the previous coating should be moistened with water. The coating direction of the second layer should be perpendicular to the direction of the first layer to complete the construction of the waterproof coating layer. Use a trowel to spread the slurry on the base surface, and apply it at a dosage of 1.2-1.8 kg / m2. Do not miss any holes. Steel plate 1 is provided with a number of through holes, and the self-compacting grouting material can pass through the through holes into the enclosed area of ​​the support bracket of steel plate 1, steel plate 2 and the original supporting corbel, so that a grouting material coating layer can also be formed at this location.

[0029] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
