Abstract
The utility model relates to a reinforcing device, which is especially used for reinforcing by a reinforced concrete structure. In the device, a flange surface at one side of each of a plurality of parallel H-type steels is fixed at the outer side of the original wall; a flange surface at the other side of each of the H-type steels is welded with a steel plate mesh; and a cavity formed by the original wall, the H-type steels and the steel plate meshes is fully filled with C20 self-compacting concrete. The reinforcing device has a simple structure and is easy to construct, the bearing capacity of the reinforcing device is greatly improved when in reinforcing by the reinforced concrete structure, and the cross sectional area of the structure is enlarged a little, therefore, the reinforcing device has strong integrity and high reliability.
Description
Technical field
The utility model relates to a kind of bracing means, especially the reinforcing of reinforced concrete structure.
Background technology
At present, to aging or have the reinforced concrete structure of disease to reinforce to be and improve its durability, prolong effective way in its application life.The encased steel reinforcing method is a kind of wider traditional reinforcement means of face that uses, and this reinforcing method is divided into wet type and two kinds of situations of dry type.Both compare, and the construction of dry type encased steel is more easy, but bearing capacity raising amount, integral working and loading characteristic are effective not as the wet type encased steel.But wet type encased steel strengthening construction is comparatively complicated, and does not rationally use steel.
Summary of the invention
In order to overcome the deficiency of existing encased steel reinforcing method, the purpose of this utility model provides the combination steel work that a kind of concrete strengthening is used, this device can increase substantially its bearing capacity when concrete structure reinforcement, make simultaneously the cross-sectional area of structure increase few again, and globality is strong, the reliability height.
Solving the scheme that technical problem of the present utility model adopts is: at a side wing edge face of the fixing many parallel H shaped steel in the outside of original wall body, the opposite side edge of a wing face weldable steel expanded metals of each H shaped steel is filled full C20 self-compacting concrete in the cavity that original wall body, H shaped steel and expanded metal lath are contained.
Described expanded metal lath is the rhombus net, and its outside also is welded with the many stiffening ribs that are parallel to each other.
The specification of described H shaped steel is HN100 * 50; Rolling and stretch-draw forms expanded metal lath by the galvanizing steel band of thick 1mm, and the mesh length of side is 10mm * 10mm; The diameter of stiffening rib is Φ 12.
H shaped steel vertically is provided with, and spacing is 400mm, fixes by the outside of viscose glue and original wall body; The stiffening rib level is to setting, and spacing is 500mm.
The beneficial effects of the utility model are can save steel significantly when satisfying the concrete structure bearing capacity, and construction to be comparatively simple; When the part that increases the cross section newly improves structural bearing capacity, also because of increasing the horizontal restrain effect of rhombus net expanded metal lath and stiffening rib newly, make former concrete structure produce good three-dimensional stress state, thereby can increase substantially the bearing capacity of structure, and construction is simple.
Description of drawings
Fig. 1 is a horizontal sectional drawing of the present utility model.
Fig. 2 is a facade section of the present utility model.
Among the figure: 1-original wall body, 2-H shaped steel, 3-expanded metal lath, 4-stiffening rib, 5-concrete.
The specific embodiment
Shown in figure, adopt high-strength plastic that one side wing edge face of H shaped steel 2 (specification is HN100 * 50) is subsidized in original wall body 1 outside to increase the concrete structure cross section, the outermost edge of a wing face of H shaped steel 2 and 3 welding of the expanded metal lath of diamond hole, expanded metal lath 3 forms with stretch-draw by the galvanizing steel band of thick 1mm is rolling, the hole length of side is 10mm * 10mm, and on expanded metal lath 3, be welded with Φ 12 stiffening ribs 4 of many levels, contain at original wall body 1, H shaped steel 2 and expanded metal lath 3 and enrich C20 self-compacting concrete 5 in the cavity that forms.
In Fig. 2, H shaped steel spacing is 400mm, adjacent H shaped steel outermost edge of a wing face and expanded steel diamond mesh welding, and set up Φ 12 stiffening ribs, stiffening rib is provided with every 500mm up and down, and fixedly expanded steel diamond mesh waters the C20 self-compacting concrete between body of wall and expanded steel diamond mesh.
