Abstract
The utility model discloses an external prestressed tensile base, which is characterized by consisting of a pull rod (1), and a left base (2) and a right base (3) with uniform structures, wherein the left base (2) is provided with an angle steel (2a); both sides of the angle steel (2a) are provided with bolt through holes; one side of the angle steel (2a) is welded with a left pull rod bracket (2b); and the two ends of the pull rod (1) are respectively connected with the left pull rod bracket (2b) of the left base (2) and a right pull rod bracket (3b) of the right base (3). The external prestressed tensile base has the remarkable effects that: sundries can be isolated, a damaged support post or a damaged bracket can be repaired quickly, the support post or the bracket can restore the original bearing capability, the bearing capability of the support post or the bracket can be enhanced, moreover, work amount is small, construction period is short, and construction cost is low.
Description
Technical field
The utility model belongs to a kind of building maintaining device, specifically, is that a kind of maintenance is subjected to along the outer prestressed stretch-draw pedestal that decreases building.
Background technology
Building uses for a long time, the pillar of its core, and crackle takes place in concrete force structures such as support easily, or is subjected to outside destroy, occurs defective easily.
The ability to bear that crackle and defective pillar occur will be had a greatly reduced quality, and can't bear the strength that is subjected to of designing requirement, have influence on the application life and the load-bearing capacity of whole building.
To this, prior art adopts often safeguards construction, adopts new pillar or support that damaged pillar is replaced, and its shortcoming is: great in constructing amount, and the construction cost height, construction period is long.
The utility model content
The purpose of this utility model provides a kind of external prestressing stretch-draw pedestal, can not only isolate out foreign material, can renovate fast impaired pillar or support, guarantee that pillar or support are returned to original ability to bear, even can improve the ability to bear of pillar or support, and engineering quantity is little, and short construction period, construction cost are low.
For achieving the above object, the utility model provides a kind of external prestressing stretch-draw pedestal, its key is: left pedestal and right pedestal by pull bar, structure unanimity are formed, wherein left pedestal is provided with angle steel, all have the bolt via hole on two limits of this angle steel, and also be welded with the left lever support on the limit of this angle steel;
The two ends of described pull bar connect the left lever support of left pedestal and the right rob support of right pedestal respectively.
Impaired when pillar or support, crackle appears and after, on the bolt via hole, pass screw, and after screw hammered into pillar, also just left pedestal and right pedestal have been fixed on the both sides of impaired crackle, pull bar is connected on left pedestal and the right pedestal again.
Rely on the pulling force of pull bar, remedy the intensity of pillar.
The two ends of described pull bar are threaded rod, after the two ends of this threaded rod are passed described left lever support and right rob support respectively, and are set with nut.
Swivel nut just can drawing pull bar, makes great efforts to make the pillar of crackle both sides to draw close to the centre, has improved the intensity of pillar, the ability to bear of lift columns.
This external prestressing stretch-draw base construction is simple, and the engineering quantity of its installation is little, and short construction period, construction cost are low.
A kind of external prestressing stretch-draw pedestal, its key is: the rectangular stress frame of forming by four pull bar first pedestal, second pedestal, the 3rd pedestal and the 4th pedestals consistent with structure,
Wherein first pedestal, second pedestal, the 3rd pedestal and the 4th pedestal are formed four angles of described rectangular stress frame respectively, and described pull bar is four limits of described rectangular stress frame;
Described first pedestal, second pedestal, the 3rd pedestal and the 4th pedestal all are provided with angle steel, all have the bolt via hole on two limits of this angle steel (a), and all are welded with rob support on two limits;
The two ends of described pull bar are connected on the rob support of two described angle steel.
If it is impaired that pillar or support have around getting, just can adopt the rectangular stress frame, realization is to the full encirclement structure of pillar, can both improve the intensity of pillar, the ability to bear of lift columns from four faces.
The two ends of described pull bar are threaded rod, after described rob support (b) is passed at the two ends of this threaded rod respectively, and are set with nut.
Remarkable result of the present utility model is: external prestressing stretch-draw pedestal simple in structure is provided, can isolate out foreign material, can renovate fast impaired pillar or support, guarantee that pillar or support are returned to original ability to bear, even can improve the ability to bear of pillar or support, and engineering quantity is little, and short construction period, construction cost are low.
