Abstract
The utility model discloses a concrete preembedded bolt/bolt sleeve positioning mechanism, relating to a building foundation preembedded part positioning technology. The utility model aims to provide a concrete preembedded bolt sleeve positioning mechanism capable of ensuring accurate positioning of a concrete preembedded bolt or a concrete preembedded bolt sleeve. The concrete preembedded bolt sleeve positioning mechanism adopts the technical proposal that the concrete preembedded bolt positioning mechanism comprises bolts and a fixed bracket; an upper fixed bracket plate at the circumference of each bolt is provided with four screw caps, among which, every two are opposite to other two screw caps; an adjusting screw stem is matched with the internal thread of each screw cap; each bolt is positioned inside a center hole of the upper end cap of a sleeve; an upper fixed bracket plate at the circumference of a bolt sleeve is provided with the four screw caps, among which, every two are opposite to other two screw caps; and the adjusting screw stem is matched with the screw hole of each screw cap. The concrete preembedded bolt sleeve positioning mechanism is used in building foundation construction.
Description
Technical field:
The utility model relates to a kind of building foundation embedded part location technology, particularly a kind of concrete embedded bolt/bolt sleeve positioning mechanism.
Background technique:
Generally adopt pre-embedded bolt or bolt collar in concrete the in place of industrial building steel structure, equipment and installation, steelframe is fixed on the foundation forms, bolt or bolt collar are fixed on the steelframe on request.After the concrete placement, bolt or bolt collar tend to be offset, and influence precision of equipment installation, influence service life of equipment.
Summary of the invention:
The purpose of this utility model provides a kind of concrete embedded bolt collar positioning means that can guarantee concrete embedded bolt or bolt collar accurate positioning.The technical solution of the utility model is, a kind of concrete embedded bolt positioning means, comprise bolt and fixing frame, it is characterized in that: be provided with four nuts facing each other on the upper holder plate around outside each bolt, the internal thread of adjusting screw rod and nut matches.Bolt places the center hole of sleeve upper end cap, is provided with four nuts facing each other on the upper holder plate around outside bolt collar, and the tapped hole of adjusting screw rod and nut matches.The utility model has the advantage of the accurate positioning of pre-buried concrete screw-bolt or bolt collar compared with the prior art.
Description of drawings:
Fig. 1 is the plan view of the concrete embedded bolt positioning means of the utility model, and Fig. 2 is the A-A sectional drawing of Fig. 1.
Embodiment:
In conjunction with above accompanying drawing the utility model is described in detail, the mechanism of existing holding down bolt sleeve is earlier with upper and lower steelframe 4,6 with the side steelframe places on the concrete foundation inner cushion layer or on the foundation forms and fixing, according to position required distance to each bolt, on last steel frame plate, open the bolt collar hole, opening bolt hole on the steel frame plate down, the lower end of bolt 5 and sleeve 1 is fixed on down on the steelframe, and sleeve is stretched in the upper holder plate outside 1 upper end.Accurate for the position that can make bolt collar, each is fixed 3, four adjusting screw rods of a nut and is spun in this nut 3 on the front, rear, left and right upper holder plate outside bolt collar of the present utility model.For bolt is overlapped with the bolt collar center, the upper end-hole of bolt collar is provided with an end cap 7, and its center has a hole and bolt shank to match.
The method that the utility model is regulated the bolt collar position is, when bolt collar occurring during ot-yet-hardened after the concrete placement displacement takes place, can make the bolt collar 1 of displacement be in the accurate position of requirement by four adjusting screw rods 2.When absolute altitude is subjected to displacement, can regulate by the bottom screw rod.
When not needing bolt collar is set, the termination of four adjusting screw rods is relative with bolt.
