Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
Embodiment 1: a kind of column underpinning device, as it is shown in figure 1, include base 1, jack 2, embrace beam 3 and support bar 4.
Base 1 is placed on the ground around column one circle and fixing with being connected by multiple bolts between ground, and jack 2 is arranged
Base 1 is fixed with being connected by multiple bolts between base 1, and by the padded jack of base 12, overcomes on jack 2
The defect that rise is short.
With reference to Fig. 2, an armful beam 3 includes four shapes, structure and size and is the same from girder steel 31, and girder steel 31 is I-steel
Or C-type steel, the present embodiment is C-type steel.Four girder steels 31 are connected two-by-two by the connection corner brace 32 of four squares and just surround
Square, it is formed with through hole 33 in embracing beam 3, through hole 33 is available for embracing a beam 3 after column passes thus ensures to install can surround column,
The bottom embracing beam 3 is connected fixing by bolt with the top of jack 2.
Multiple connecting hole it is provided with in corner brace 32 and girder steel 31, and the type channel opening court of girder steel 31 C-type steel when mounted
Outward (direction of column dorsad), during installation, the two-arm of corner brace 32 is respectively embedded in the type groove of two girder steels 31, and is worn by bolt
Corner brace 32 is fixed on girder steel 31 by the connecting hole crossed on corner brace 32 and girder steel 31, and the connection simultaneously realizing two girder steels 31 is fixed.
With reference to Fig. 1, the two ends of support bar 4 are provided with the connecting plate 41 vertical with support bar 4 length direction, support bar 4
By being fixedly welded on the middle part of connecting plate 41, the position being positioned at support bar 4 both sides at connecting plate 41 is provided with installing hole for spiral shell
Bolt is through being attached fixing.One end of support bar 4 is fastened on the top embracing beam 3 by connecting plate 41, on the other end
Connecting plate 41 beam abuts and passes through connecting plate 41 and is connected with beam fixing.
