Description
Technical field
The present invention relates to old building reinforcing technique, more particularly, relate to a kind of permanent reinforcing device for old buildings and method.
Background technology
Due to of the remote past, body of wall is aging, causes old building overall structure weakness, in order to protect better old building, need to carry out permanent reinforcing to old building.At present, conventional reinforcing mode is first the body of wall of old building to be chiseled, and then the structural column newly doing and structural beams is embedded in body of wall, thereby is formed for the entirety of reinforcing.But which is larger to the destruction of old building body of wall, be also unfavorable for keeping the original appearance of the outer facade of old building body of wall simultaneously.
Therefore, how can either old building effectively be reinforced, can reduce again the destruction to old building wall body structure, keeping to greatest extent its original appearance is current building engineering field urgent problem.
Summary of the invention
For the above-mentioned shortcoming existing in prior art, the object of this invention is to provide a kind of permanent reinforcing device for old buildings and method, in order to old building is carried out to permanent reinforcing, reduce the destruction to its body of wall.
For achieving the above object, the present invention adopts following technical scheme:
This permanent reinforcing device for old buildings, comprising:
Load-bearing frame, is located at old building inside;
Several pilasters, are attached at respectively on old building body of wall inwall, and are connected and fixed integral with load-bearing frame;
Tension rib, one end is implanted in body of wall fixing, and the other end anchors in pilaster.
Between described pilaster and body of wall inwall, scribble anti-water base cement sand bed.
Described pilaster and load-bearing frame adopt steel concrete to make.
Described tension rib adopts and is the chemical bolt that plum blossom-shaped is arranged, and weld mutually with the reinforcing cage in pilaster the one end anchoring in pilaster.
The concrete steps of this reinforcement means are as follows:
A. on the inwall of old building body of wall, implant tension rib;
B. set up the reinforcing cage of pilaster at the body of wall inwall place that is implanted with tension rib, and weld mutually with the tension rib other end;
C. pour into a mould pilaster, and the tension rib other end is cast in pilaster;
D. at the load-bearing frame of the inner casting reinforced concrete of old building, and by load-bearing frame and each pilaster pour into a mould be connected and fixed integral.
Between described step B, C, before being also included in cast pilaster, on the corresponding inwall of body of wall, be coated with the step of anti-water base cement mortar.
In described steps A, select chemical bolt as tension rib, and be plum blossom-shaped implantation body of wall inwall.
In technique scheme, permanent reinforcing device for old buildings of the present invention comprises to be located at the load-bearing frame of old building inside, to be attached at several pilasters of being connected on old building body of wall inwall and with load-bearing frame, tension rib for connecting wall and pilaster respectively.Reinforcement means of the present invention is included in old building body of wall inwall and implants tension rib, sets up pilaster reinforcing cage, the cast pilaster welding mutually with tension rib and the load-bearing frame being connected with pilaster in the inner cast of old building.Owing to adopting in old building inside by load-bearing frame being set and pilaster is reinforced load, and carry out body of wall drawknot by tension rib and fix, thereby reduce the destruction to body of wall, and kept the original appearance of the outer facade of old building body of wall, played good permanent reinforcement effect.
Brief description of the drawings
Fig. 1 is the partial top view of the permanent reinforcing device of being located at old building inside of the present invention;
Fig. 2 is the sectional view along A-A line in Fig. 1;
Fig. 3 is the flow chart of the permanent reinforcement means of old building of the present invention.
Detailed description of the invention
Further illustrate technical scheme of the present invention below in conjunction with drawings and Examples.
Shown in Fig. 1,2, permanent reinforcing device for old buildings 100 of the present invention comprises load-bearing frame 110, several pilaster 120 and tension rib 130, and load-bearing frame 110 is located at old building inside; Pilaster 120 is attached at respectively on the inwall of old building body of wall 1, the distributing position of pilaster 120 considers the force request of old building internal framework and needs body of wall 1 node location of reinforcing to distribute, as in the middle of body of wall 1, the position that needs reinforcement of body of wall 1 turning and body of wall 1 other weakness, and be connected and fixed integral with load-bearing frame 110; Tension rib 130, it is interior fixing that body of wall 1 is implanted in one end, and the other end anchors in pilaster 120, and meets anchorage length requirement, and for the drawknot between body of wall 1 and pilaster 120 and fixing, and the implantation end of tension rib 130 does not penetrate body of wall 1 outer wall.It should be noted that at this, load-bearing frame 110 all can adopt steel concrete pouring type to make with pilaster 120, and tension rib 130 can be selected the chemical bolt that is plum blossom-shaped layout, and in the time making the reinforcing cage of pilaster 120, the other end of tension rib 130 and reinforcing cage are welded together, can tension rib 130 is fixing with pilaster 120 by cast.Corrode body of wall 1 for the concrete alkali lye of the pilaster 120 that prevents from being affixed with body of wall 1 exosmoses, can coat anti-water base cement sand bed 140 in the contact site between pilaster 120 and body of wall 1 inwall, thereby play the effect of protecting interface.
Please, again in conjunction with shown in Fig. 3, the concrete steps of the permanent reinforcement means of this old building are as follows:
A. on the inwall of old building body of wall 1, implant tension rib 130;
B. set up the reinforcing cage of pilaster 120 at the body of wall 1 inwall place that is implanted with tension rib 130, and weld mutually with tension rib 130 other ends;
C. pour into a mould pilaster 120, and tension rib 130 other ends are cast in pilaster 120;
D. at the load-bearing frame 110 of the inner casting reinforced concrete of old building, and load-bearing frame 110 and each pilaster 120 cast are connected and fixed integral.
Between step B, C, before being also included in cast pilaster 120, on the corresponding inwall of body of wall 1, be coated with the step of anti-water base cement mortar, thereby protect interface together with forming between body of wall 1 and pilaster 120.
In steps A, can select chemical bolt as tension rib 130, and be plum blossom-shaped implantation body of wall 1 inwall.
It should be noted that at this, a part that also can be using pilaster 120 as whole load-bearing frame 110, is that load-bearing frame 110 contacts with body of wall 1 part being connected, and therefore pilaster 120 and the reinforcing cage of load-bearing frame 110 can be set up simultaneously to cast simultaneously.
Permanent reinforcing device for old buildings 100 of the present invention and method, by adopting in old building inside by load-bearing frame 110 being set and pilaster 120 is reinforced load, and carry out body of wall 1 drawknot by tension rib 130 and fix, whole old building body of wall 1 is connected with bracing means 100, and bracing means 100 is protected old building body of wall 1 from inner support just as a structure inner bag, thereby play effective reinforcement effect, and carry out insert structure post without chiseling in a large number body of wall 1, therefore greatly reduced the destruction to body of wall 1, and keep the original appearance of old building body of wall 1 outer facade, play good permanent reinforcement effect, be conducive to keep the original appearance of old building body of wall 1 outer facade simultaneously, effect is very remarkable.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, variation, modification to the above embodiment all will drop within the scope of claims of the present invention.
