Abstract
The utility model discloses a deviation-rectifying sleeve of an embedded bolt of a concrete foundation and relates to the field of construction device of the concrete foundations of buildings. The deviation-rectifying sleeve comprises an outer sleeve and a metal framework, wherein the outer sleeve is barrel-shaped and is provided with a vertical through hole, and the embedded bolt can penetrate through the through hole. The metal framework is fixed inside an outer sleeve wall, the upper end of the metal framework extends out of the upper portion of the outer sleeve, and the extended portion of the upper end of the metal framework is provided with a pulling connection point for pulling the outer sleeve with external force. The deviation-rectifying sleeve can solve the problem of difficult adjustment of the embedded bolt due to concrete setting, enable the embedded bolt to be finely adjusted in the front direction, the back direction, the left direction and the right direction, improve the embedding accuracy of the embedded bolt, enable a bolt to be embedded in one time and improve the work efficiency.
Description
Technical field
The utility model relates to the concrete foundation construction equipment of building, particularly concrete foundation pre-embedded bolt correction cover.
Background technology
Along with the fast development of Chinese national economy, all kinds of large industry equipments are installed and the large-scale steel structure factory building constantly increases, and the pre-buried quantity of pre-embedded bolt of all kinds of concrete foundations (especially large industry equipment concrete foundation) is more and more huger.In the prior art, concrete foundation erection bolt mode mainly contains two kinds: one of which, and the prepared screw-bolt hole erection bolt, this kind mode receives the construction quality factor affecting more, and back yard industry equipment is taked this mode more; Its two, pre-embedded bolt, large industry equipment vibrations are big, quality is big, rotating speed is high, generally adopts pre-embedded bolt.Large equipment base pre-embedded bolt specification is many, quantity is big and construction precision requires highly, has produced bigger deviation and will influence directly that equipment is installed, operation in case indivedual bolt is pre-buried, influences installation progress and production time.
In the pre-buried process of bolt, usually run into following problem: after having built concrete, find that pre-embedded bolt has little deviation; In order to guarantee pre-buried precision; Minimizing is done over again because of the installation that pre-buried precision problem brings, and people urgently hope after concrete final set, can also finely tune bolt.
The utility model content
The technical problem that the utility model will solve is to above-mentioned deficiency of the prior art; A kind of concrete foundation pre-embedded bolt correction cover is provided; This correction cover can be eliminated the adjusting difficulty because of pre-embedded bolt after the concrete setting, makes pre-embedded bolt can carry out the fine setting of front, rear, left and right four direction, and can improve the pre-buried precision of pre-embedded bolt; The pre-buried once one-tenth of bolt is lived, increase work efficiency.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of concrete foundation pre-embedded bolt correction cover comprises overcoat and metallic framework; Overcoat is tubular, is provided with the through hole of up/down perforation, and pre-embedded bolt can pass from this through hole; Metallic framework is fixed in the overcoat wall, and extend out to the overcoat top on the metallic framework, and this metallic framework upper end extension is provided with and is used for socketing a little of external force pulling overcoat.
The beneficial effect of the utility model is: in concrete pouring construction, pre-embedded bolt is put carry out concreting again after correction is overlapped earlier, after concrete final set; A little pull out overcoat through socketing of metallic framework of external force pulling; If the pre-embedded bolt precision has deviation, can realize the fine setting of the horizontal front, rear, left and right of pre-embedded bolt four direction, if the pre-embedded bolt precision meets the demands; Then gap between pre-embedded bolt and the concrete (being the shared volume of overcoat) grouting is filled and handle; Thereby the utility model can improve the pre-buried precision of pre-embedded bolt, makes that bolt is pre-buried once to be become to live, and increases work efficiency.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the overall structure sketch map of the utility model.
Fig. 2 combines the user mode sketch map of pre-embedded bolt in concrete for the utility model.
Among the figure, 1. correction is overlapped; 11. overcoat; 12. metallic framework; 121. socket a little; 13. through hole; 2. pre-embedded bolt; 3. concrete.
The specific embodiment
As depicted in figs. 1 and 2, concrete foundation pre-embedded bolt correction cover 1 comprises overcoat 11 and metallic framework 12; Overcoat 11 is tubular, is provided with the through hole 13 of up/down perforation, and pre-embedded bolt 2 can pass from this through hole 13; Metallic framework 12 is fixed in overcoat 11 walls, and metallic framework 12 upper ends extend out to overcoat 11 tops, these metallic framework 12 upper end extensions be provided be used for external force pulling overcoat 11 socket a little 121.
As depicted in figs. 1 and 2, in technique scheme, the shape of metallic framework 12 is spring shape.
As the optimal way of technique scheme, said overcoat 11 is preferably rubber sleeve, said metal
As shown in Figure 2; In concrete 3 pouring constructions, earlier pre-embedded bolt 2 is put and carry out concrete 3 again behind the correction cover 1 and build, after concrete 3 final set; 121 pull out overcoat 11 through socketing a little of metallic framework 12 of external force pulling; With after these overcoat 11 taking-ups pre-embedded bolt 2 being measured,, can carry out the fine setting (laterally pulling pre-embedded bolt 2) of forward and backward, left, the swollen four direction of level to pre-embedded bolt 2 if pre-embedded bolt 2 precision have deviation; If pre-embedded bolt 2 precision meet the demands, then gap between pre-embedded bolt 2 and the concrete 3 (being overcoat 11 shared volumes) grouting is filled and handle.
The above only is the utility model preferred embodiments, and every any trickle modification, equivalent variations and modification of above embodiment being done according to the technical scheme of the utility model all belongs in the scope of the utility model technical scheme.
