Abstract

The utility model discloses a fixed structure of a pre-embedded bolt in a cast-in-place concrete structure, comprising a fixed support frame and the pre-embedded bolt, wherein the fixed support frame comprises a bottom pre-embedded part and an auxiliary support frame, wherein the auxiliary support frame is welded on the bottom pre-embedded part; a top horizontal frame of the auxiliary support frame is provided with a through hole; the pre-embedded bolt penetrates through the through hole so as to be screwed and fixed with a screw cap arranged on the top horizontal frame; and the outer ring of the screw cap arranged on the top horizontal frame is welded with a horizontal fine-adjustment bolt. The utility model has fast construction speed and high pre-embedded precision, not only enhances the work efficiency, but also ensures the construction quality, and creates good conditions for sequential work.

Description

The fixed structure of pre-embedded bolt in the cast-in-situ concrete structure
Technical field
The utility model design building construction field specifically is the fixed structure of pre-embedded bolt in a kind of cast-in-situ concrete structure.
Background technology
In the construction of structure concrete, equipment is fixed and the requirement of subsequent technique in order to satisfy, and often has a large amount of pre-embedded bolts to need carry out in the concrete casting process accurately pre-buried and fixing.Particularly in the industrial building structure concrete, the pre-buried quantity of bolt is big, precision prescribed is high, time-consuming, precision control difficulty is bigger.If no reliable fixation though precision meets the requirements before the concrete cast, because of causes such as lateral pressure is bigger in the concrete casting process, tends to cause pre-embedded bolt skew or bending, cause and to use.Both incur loss through delay the duration, caused unnecessary loss again.Particularly the pre-embedded bolt in prevention of mass concrete or the unsettled concrete member very easily can cause a hidden trouble to subsequent handling, not only can't ensure the quality of products, and can cause bigger economic loss to engineering.
For many years, the method for pre-embedded bolt all adopts traditional pre-buried method in the cast-in-situ concrete structure, mainly contains direct pre-buried method, steel pipe truss fixation, cage of reinforcement fixation, wooden frame fixation etc.But after the concrete cast, its pre-embedded bolt precision often can not satisfy design or code requirement, causes unnecessary doing over again and economic loss.
The utility model content
The technical problems to be solved in the utility model provides the fixed structure of pre-embedded bolt in a kind of cast-in-situ concrete structure, solved and adopted the randomness of traditional handicraft pre-embedded bolt big for a long time, cause the pre-embedded bolt low precision, can not satisfy the needs of subsequent handling, stop that secondary is done over again and unnecessary economic loss.
The technical solution of the utility model is:
The fixed structure of pre-embedded bolt in the cast-in-situ concrete structure, comprise fixed support and pre-embedded bolt, described fixed support comprises bottom built-in fitting and auxiliary stand, described auxiliary stand is welded on the built-in fitting of bottom, have through hole on the top level frame of auxiliary stand, described pre-embedded bolt passes the nut that is provided with on through hole and the top level frame and screws togather fixingly, and the outer ring that is positioned at nut on the level frame of described top is welded with the WidFin bolt.
The aperture of described through hole is greater than the screw diameter of pre-embedded bolt; Described nut race diameter is greater than the aperture of through hole.
Be fixedly welded with reinforcing crossmember support and cross fixation support on the described auxiliary stand.
The utility model employing auxiliary stand and nut are tentatively fixing with pre-embedded bolt, in the concrete work progress, regulate nut at any time according to the absolute altitude that level gauge is measured, and be accurate with the absolute altitude position of guaranteeing bolt.
The utility model adopts the outer ring spot welding WidFin bolt that is positioned at nut on auxiliary stand, in the concrete work progress, as required the horizontal level of pre-embedded bolt is adjusted at any time, and is accurate with the horizontal level of guaranteeing pre-embedded bolt.
Speed of application of the present utility model is fast, and pre-buried precision height has not only improved operating efficiency, and has guaranteed construction quality, for good condition has been created in follow-up work; Pre-embedded bolt off-centring value compliant is less than the requirement of 2.0mm; Satisfying pre-embedded bolt exposed length deviation simultaneously is 0<L≤30mmm, and the reach deviation is the code requirement of 0<S≤30mm.Owing to the utlity model has characteristics such as practical, in similar engineering construction, have promotional value and application prospect widely.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the vertical view of the auxiliary stand among the utility model embodiment.
The specific embodiment
The utility model embodiment: the fixed structure of pre-embedded bolt in the cast-in-situ concrete structure, comprise fixed support and pre-embedded bolt 5, fixed support comprises bottom built-in fitting 1 and auxiliary stand 2, auxiliary stand 2 is welded on the built-in fitting 1 of bottom, have through hole 3 on the top level frame of auxiliary stand 2, pre-embedded bolt 5 passes the nut 4 that is provided with on through hole 3 and the top level frame and screws togather fixingly, and the outer ring point that is positioned at nut 4 on the level frame of top is welded with WidFin bolt 6.
The aperture of through hole 3 is greater than the screw diameter of pre-embedded bolt 5, promptly satisfy pre-embedded bolt 5 and can carry out horizontal movement in the horizontal direction, and the WidFin bolt by nut 4 outer rings cooperatively interacts and props up engaging pre-embedded bolt 5, guarantees in the horizontal direction fixing of pre-embedded bolt; Nut 4 race diameters promptly satisfy nut and are positioned on the auxiliary stand 2 greater than the aperture of through hole 3, can not pass through hole, and pre-embedded bolt and nut screw togather fixing, have guaranteed the fixing of pre-embedded bolt in the vertical direction.
When the height of auxiliary stand 2 is higher than five meters, fixedly be welded with reinforcing crossmember support 7 and cross fixation support 8 on the auxiliary stand, strengthened the stability of auxiliary stand.
