The purpose of the utility model is accomplished by following technical scheme:
A kind of high accuracy precast beam location structure; Comprise two beam columns and a precast beam, it is characterized in that: also comprise at least one by the positioner that locating rack and alignment pin constitute, the detachable beam column side of another beam column relatively of being fixed in of said locating rack; And has a location-plate that a horizontal-extending is provided with; Offer a locating hole on the said location-plate, said alignment pin is detachable to be fixed on the bottom surface of said precast beam end, and can be plugged in the said locating hole/from said locating hole, extract out.
The quantity of said location structure is two, and the locating rack in said two location structures is located at two sides that beam column is relative respectively, and the alignment pin in said two location structures is located at the bottom surface at precast beam both ends respectively.
Said locating rack comprises a fixed head, said fixed head fit said beam column side and bolt, and said location-plate vertical fixing is in this fixed head upper limb.
The both side edges of said fixed head and location-plate is provided with floor.
Said alignment pin comprises coaxial circular cone body and the cylinder part that joins, said cylinder part end face and said precast beam bottom surface bolt, and said locating hole is a circular hole, and its diameter is identical with said cylinder part diameter.
Be embedded with at least one on the said precast beam and be used for the nut with said alignment pin bolt, be embedded with some nuts that are used for said locating rack bolt at least one beam column.
The utility model has the advantages that: the positioning accuracy during installation is high, Stability Analysis of Structures; It is simple and convenient to construct, and has saved duration and manpower and materials greatly; Orientation tool is simple in structure, reusable, and is with low cost.

Fig. 4 is embodiment 2 location structure general illustration.
The specific embodiment
Through embodiment the utility model characteristic and other correlated characteristic are done further explain below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-4, mark 1-14 is respectively among the figure: first beam column 1, second beam column 2, precast beam 3, positioner 4, locating rack 5, fixed head 6, location-plate 7, locating hole 8, alignment pin 9, circular cone body 10, cylinder part 11, bolt 12, nut 13, floor 14.
Be elaborated for high accuracy precast beam location structure below in conjunction with embodiment:
Embodiment 1:
Shown in Fig. 1-3, the related location structure of present embodiment mainly is made up of first beam column 1, second beam column 2, precast beam 3 and two positioners 4.Wherein first beam column 1 and second beam column 2 are provided with perpendicular to ground, and the two ends of precast beam 3 are held on respectively on first beam column 1 and second beam column 2.The upper end of the two sides that wherein first beam column 1 is relative with second beam column 2 is embedded with some nuts 13, and the bottom surface at the two ends of precast beam 3 is embedded with a nut 13 respectively.
In conjunction with above-mentioned location structure, below be elaborated for the present embodiment operational method:
Before precast beam 3 lifting, two alignment pins 9 of bolt on precast beam 3 at first; Said locating rack 5 meanwhile is installed on first beam column 1 and second beam column 2.
Hoisting prefabricated afterwards beam 3 to first beam columns 1 and second beam column, 2 tops, and pass through instrument its horizontal levels of adjustment such as crane or Chain block so that the locating hole 8 on two locating racks 5 of two alignment pin 9 difference correspondences.When precast beam 3 is in the state of lifting; Moving on the horizontal direction only need overcome its inertia and get final product, and can be found out that by above-mentioned structure alignment pin 9 lower ends have a circular cone body 10; So when the summit of this circular cone body 10 is dropped in the scope of locating hole 8; When precast beam 3 fell, the side of circular cone body 10 contacted with locating hole 8 and slides, and got in the locating hole 8 and matched in clearance until cylinder part 11.Because cylinder 11 shapes size and locating hole 8 match, accomplish so can be considered precast beam 3 location.The size of above-mentioned circular cone body 10, cylinder part 11 and locating hole 8; Should decide according to the mobile accuracy that crane or Chain block etc. is used for instrument that precast beam 3 moves horizontally and can provides; When its precision was low, the summit that locating hole 8 bore size should increase to ensure circular cone body 10 can fall within it.
Fall said precast beam 3 so that it is held on the upper end of first beam column 1 and second beam column 2 through the operation crane afterwards, and two alignment pins 9 are plugged in respectively in two locating holes 8, this moment, accomplished the location.
Embodiment 2:
Referring to accompanying drawing 4, described location structure of present embodiment and embodiment 1 are roughly the same.Different is only to adopt a positioner 4, has only simultaneously to be embedded with some nuts 13 on first beam column 1, has only the bottom surface of an end of relative first beam column 1 to be embedded with nut 13 on the precast beam 3, is used for mounting and positioning device 4.Adopt this kind location structure, precast beam 3 one ends adopt alignment pin 9 to locate, and the other end is then the same with prior art, and with the precast beam position that falls, promptly the precast beam 3 back end in position that falls is located and other end no-fix with the position that roughly coincide.When operation, compare with the step of embodiment 1, then increased following steps: precast beam 3 falls behind the position, is rotating shaft with alignment pin 9, carries out the position of trickle adjustment precast beam 3 other ends through instruments such as jack.The relative embodiment 1 of this kind structure has increased the step of construction, has increased the cycle of construction.The purpose that is provided with so mainly be precast beam 3 when lifting, if equipment precision is not high, be difficult to accomplish two alignment pins 9 corresponding locating hole 8 simultaneously according to location structure among the embodiment 1, the position of only controlling a side alignment pin 3 is then relatively easy.
