Description
Technical field
The utility model relates to a kind of bracing means of concrete column, can be used for the technical field of building reinforce.
Background technology
Concrete column in use, often can be subject to the impact of external load, causes its part to be damaged, thereby affects its load performance.In serious situation, even likely can cause caving in of building.In prior art, in the time concrete column being carried out to part reparation, be to smear cement mortar at breakage mostly, make the outward appearance of concrete column look there is no damage.But this processing mode can cause the connection defective tightness between cement mortar and original structure thing, can not make the load level of concrete column significantly be improved.
Therefore, in prior art, need to provide that a kind of globality is better, the bracing means of the concrete column of bearing capacity higher level.
Utility model content
The utility model provides a kind of bracing means of concrete column, and it can overcome above-mentioned shortcoming of the prior art.
According to the bracing means of concrete column of the present utility model, comprise steel bushing, annular stop device, expansion bolt anchor system and connector, steel bushing is arranged on concrete column around, between concrete column and steel bushing, be filled with grouting material, at the two ends up and down of steel bushing, the first flange and the second flange are set respectively, annular stop device is separately positioned on the first flange and the second flange; Expansion bolt anchor system is separately positioned on the below of the first flange and the top of the second flange, expansion bolt anchor system comprises expanding screw screw bolt and nut, one end of expansion bolt is fixed to the inside of concrete column, nut is anchored at the other end of expansion bolt on the outer wall of steel bushing, is arranged at intervals with connector along the longitudinal direction of steel bushing.
Preferably, can and be placed between the annular stop device on the first flange and the second flange and be placed between the annular stop device on the second flange seal is set at the first flange.
Preferably, on the inwall of steel bushing, stiffening rib can be set.
According to the bracing means of concrete column of the present utility model, its construction is convenient, bearing capacity level is high, can ensure the safety of building.
Brief description of the drawings
Fig. 1 is according to the schematic diagram of the bracing means of concrete column of the present utility model.
Fig. 2 is A-A line sectional view in Fig. 1.
Fig. 3 is the schematic diagram of the preferred embodiment of the bracing means of concrete column.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing, embodiment of the present utility model is elaborated.It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can be combined mutually.
Referring to Fig. 1-2, wherein show that, according to the bracing means for concrete column of the present utility model, this bracing means comprises steel bushing 2, annular stop device 3, expansion bolt anchor system, connector 6.
Steel bushing 2 is arranged on concrete column 1 around, the damaged part of the enough oversite concrete posts 1 of its length.Between concrete column 1 and steel bushing 2, be filled with grouting material.The first flange 41 and the second flange 42 are set respectively at the two ends up and down of steel bushing 2.Annular stop device 3 is separately positioned on the first flange 41 and the second flange 42, for limiting the distance between steel bushing 2 and concrete column 1.Preferably, can also be between the first flange and the annular stop device on it, seal (not shown) be set respectively between the second flange and the annular stop device on it.
Expansion bolt anchor system is separately positioned on the below of the first flange 41 and the top of the second flange 42, and it comprises expansion bolt 51 and nut 52.One end of expansion bolt 51 is fixed to the inside of concrete column 1, and nut 52 is anchored at the other end of expansion bolt 51 on the outer wall of steel bushing 2.
As shown in Figure 2, wherein shown the sectional view in A-A cross section in Fig. 1.As shown in the figure, steel bushing 2 is arranged at intervals with connector 6 on longitudinal direction from top to bottom, for steel bushing 2 is fastening at its snap close place.
Preferably, as shown in Figure 3, in the time that the length of damaged part is larger, stiffening rib 7 can be set on the inwall of steel bushing 2 to improve the yield strength of steel bushing 2.
Adopt bracing means of the present utility model, the injury region of rehabilitating concrete post fast, the load performance of raising concrete column, the safety of guarantee building.
Although the disclosed embodiment of the utility model as above, the embodiment that described content just adopts for the ease of understanding the utility model, not in order to limit the utility model.Technician under any the utility model in technical field; do not departing under the prerequisite of the disclosed spirit and scope of the utility model; can do any amendment and variation what implement in form and in details; but scope of patent protection of the present utility model, still must be as the criterion with the scope that appending claims was defined.
