Abstract
The utility model discloses a high-precision positioning fixture for large-scale pre-buried bolts. The high-precision positioning fixture for large-scale pre-buried bolts comprises four adjusting mechanisms and a positioning plate, wherein positioning holes are formed on the positioning plate; the internal diameters of the positioning holes are larger than the external diameters of the pre-buried bolts by 0.7 mm to 0.9 mm; and each adjusting mechanism comprises a base, wherein a set screw nut is fixedly connected onto the base, an adjusting bolt is in threaded connection with the set screw nut in the vertical direction; and the positioning plate is arranged at the top of the adjusting screw in a supporting manner. Through the adoption of the fixture, the leveling and the positioning of the bolts can be guaranteed; and during the using process, the upper parts of the bolts are fastened through screw caps, the middle and the bottoms of the bolts adopt horizontal and inclined spot welding through corresponding reinforcement bars, so that the bolts can not displace vertically and horizontally, and the pre-control parameter requirements for construction are ensured.
Description
Technical field
The utility model relates to positioning fixture, relates in particular to the high-precision fixed position fixture of large-scale pre-embedded bolt.
Background technology
Solve the hi-Fix problem of large-scale pre-embedded bolt in work progress, absolute altitude, the location of adjusting large-scale bolt are difficult point, the emphasis in work progress.The patent No. is that the Chinese patent of CN200410058289.9 discloses " sleeve is used in a kind of stone bolt location ", and this location in the position, bottom that outer peripheral face has the main body of all faces of polygon that rotate usefulness, is provided with the stone bolt screwed hole that screws togather with stone bolt with sleeve; In top bit; Be received in the set bolt that end face has the polygonal hole of rotation usefulness with screw-in version), between stone bolt screwed hole and set bolt, be provided with pressing body, in pressing body; Screwing togather between foot bolt screwed hole and the stone bolt concomitantly; Contact with the bottom face of the threaded shank of set bolt with the top end face of stone bolt, make stone bolt and main body be in the stationary state of double nut effect, in addition; In pressing body, the top end face of stone bolt and the bottom face of set bolt) the contact site be dome shape.This device is used for the individually implantation of foot bolt, can not carry out hi-Fix.The patent No. is that the Chinese patent of CN201020267898.6 discloses " stone bolt positioner "; This device comprises rigid platfor, fixing steel plate, pad; Fixing steel plate is fixed on the rigid platfor; Fixing steel plate is provided with locating hole, and the upper end of stone bolt is fixed by nut after passing locating hole on the fixing steel plate, pad successively.This device can easily not dismantled because rigid platfor and fixing steel plate are one, has reduced operating efficiency, and the while can not be according to the situation at the scene verticality to stone bolt, and absolute altitude is accurately adjusted the location.This device is used for the location of group's bolt, is not suitable for single bolt location.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of can be well with the pre-embedded bolt location and guarantee that the large-scale pre-embedded bolt of its levelness, absolute altitude uses high-precision fixed position fixture.
The large-scale pre-embedded bolt of the utility model is used high-precision fixed position fixture; It comprises four guiding mechanisms and location-plate, on described location-plate, is provided with locating hole, and the internal diameter of described locating hole is than the big 0.7mm-0.9mm of external diameter of pre-embedded bolt; Each described guiding mechanism comprises base; On described base, be fixedly connected with hold-down nut, the adjustment screw rod that on described hold-down nut, vertically has been threaded, location-plate supports the top that is arranged on described adjustment screw rod.
Adopt these anchor clamps can guarantee bolt level and location, in use bolt top adopts that nut is fastening, bolt middle part and bottom adopt corresponding reinforcing bar level and oblique spot welding, makes it not produce displacement with level up and down, has guaranteed that construction controls parameter request in advance.
Description of drawings
Fig. 1 is the location-plate structural representation of the large-scale pre-embedded bolt of the utility model with high-precision fixed position fixture;
Fig. 2 is the structural representation of the large-scale pre-embedded bolt of the utility model with the guiding mechanism of high-precision fixed position fixture;
Fig. 3 is used for the sketch map of pre-embedded bolt location for location-plate shown in Figure 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done to describe in detail.
The large-scale pre-embedded bolt of the utility model is used high-precision fixed position fixture shown in accompanying drawing; It comprises location-plate 1 and four guiding mechanisms; On described location-plate 1, be provided with locating hole 2; The internal diameter of described locating hole 2 is than the big 0.7mm-0.9mm of external diameter of pre-embedded bolt 3, and each described guiding mechanism comprises base 4, on described base, is fixedly connected with hold-down nut 5; On described hold-down nut, vertically be threaded and adjusted screw rod 6, location-plate supports the top that is arranged on described adjustment screw rod.
The method for using of these anchor clamps is following:
(internal diameter is only than design bolt external diameter big 0.7-0.9mm to utilize the locating hole of special fixture location-plate; And its center is consistent with design) pre-embedded bolt is positioned; When stone bolt was placed in wherein, the maximum displacement deviation that each bolt can produce was 0.35-0.45mm, and the maximum displacement deviation that any two bolts can produce is 0.7-0.9mm just; Characteristics based on special fixture itself; Precision control better, therefore as long as special fixture is installed with guiding mechanism and employing level and vertical guiding mechanism accurately after the adjustment, just can guarantee that the stone bolt precision of being inserted in the anchor clamps is controlled within the scope of design to pre-embedded bolt through total powerstation.
Anchor clamps are installed by guiding mechanism independently in advance, and four jiaos are adopted guiding mechanisms, regulate the guiding mechanism on four jiaos; Spirit level through being provided with at the anchor clamps periphery is a benchmark, makes anchor clamps on same horizontal plane, then guiding mechanism is fixed; Again pre-embedded bolt only is inserted in the locating hole than the big 0.7mm-0.9mm of its external diameter; The pre-embedded bolt bottom is provided with the vertical guiding mechanism jack of bolt (being used to regulate the bolt absolute altitude), and level gauge or total powerstation control bolt top mark height are adopted in the bolt top, and it is controlled within the same design elevation; Top, bolt top nut is fastening, it is not produced move up.
