B, stationary positioned plate, with the center of the locating hole on location-plate and the mark preliminary coincidence on structure reinforcing bars, accurately check and approve the center of locating hole by measuring apparatus after, bearing bar on location-plate is welded on structure reinforcing bars, thereby location-plate and structure reinforcing bars are connected and fixed, and the diameter of described locating hole is slightly larger than the conehead external diameter of embedded anchor cone;
C, fixing embedded anchor cone penetrate the embedded anchor cone that is connected with dowel in locating hole on location-plate, keep the conehead of embedded anchor cone to flush with the lateral surface of location-plate;
D, adopt canvas cloth with the locating hole that exposes on location-plate and the conehead shutoff protection of embedded anchor cone, cement grout stops up the anchor cone taper hole when avoiding concreting;
E, frame shuttering, and keep the lateral surface of location-plate to overlap with the medial surface of template;
F, concreting notice that in casting process reinforcement is to the protection of location-plate and embedded anchor cone;
G, when concrete reaches some strength, stripping cleans out the location-plate that is cast in concrete and the conehead of embedded anchor cone, can use pre-buried anchor cone.
In above-mentioned step D, also include according to the position of being close on location-plate, make mark at the another side of template, according to the mark on template, determine the position of location-plate when being convenient to form removal.
In above-mentioned step C, also comprise and adopt the bearing diagonal reinforcing bar with dowel and structure reinforcing bars welding, thereby embedded anchor cone and structure reinforcing bars are connected and fixed.
Above-mentioned bearing bar is distributed in four jiaos of location-plate, and the bearing bar other end and structure reinforcing bars are welded to connect.
Above-mentioned location-plate adopts the thick steel plate materials of 5mm to make.
Above-mentioned canvas cloth is the cloth that plastic colloidal cloth or other waterproofing materials are made.
The technique effect that the present invention obtains:
1. carry out setting-out according to the embedded anchor cone position of design before the construction on the location-plate face, then drive locating hole on the plate face, be welded on structure reinforcing bars in the storehouse by its installation site of measuring apparatus precise calibration and with location-plate, after thereby the position that makes location-plate is fixing, reach the purpose of embedded anchor cone position, accurate location, both reduce difficulty of construction, also accelerated construction speed, improved production efficiency;
2. adopt many bearing bars that location-plate and embedded anchor cone are weldingly fixed on structure reinforcing bars in the storehouse, fastness and the stability of embedded anchor cone have been strengthened, embedded anchor cone can be interfered in concreting process and be subjected to displacement, having guaranteed the construction quality of embedded anchor cone;
3. by the fixing anchor cone of the locating hole offered on location-plate, do not need perforate on template, kept the integrity of template, extended the application life of template, reduced cost of production.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is this location-plate schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
Referring to Fig. 1-2, a kind of embedded anchor cone accurate positioning method comprises the following steps:
A, according to the structure reinforcing bars 6 in designing requirement colligation concrete storehouse, qualified by inspection after, adopt measuring instrument to emit the burial place of embedded anchor cone 1, and make mark on structure reinforcing bars 6;
B, stationary positioned plate 2, with the center of the locating hole 3 on location-plate 2 and the mark preliminary coincidence on structure reinforcing bars 6, accurately check and approve the center of locating hole 3 by measuring apparatus after, bearing bar 4 on location-plate 2 is welded on structure reinforcing bars 6, thereby location-plate 2 and structure reinforcing bars 6 are connected and fixed;
C, fixing embedded anchor cone 1, the embedded anchor cone 1 that is connected with dowel 5 is penetrated in locating hole 3 on location-plate 2, keep the conehead of embedded anchor cone 1 to flush with the lateral surface of location-plate 2, then adopt bearing bar 4' with dowel 5 and structure reinforcing bars 6 welding, thereby embedded anchor cone 1 and structure reinforcing bars 6 are connected and fixed, the diameter of described locating hole 3 is slightly larger than the conehead external diameter of embedded anchor cone 1, gets final product with the conehead that can pass embedded anchor cone 1;
D, adopt plastic colloidal cloth with the locating hole 3 that exposes on location-plate 2 and the conehead shutoff protection of embedded anchor cone 1, cement grout stops up the anchor cone taper hole when avoiding concreting;
