Description
Technical Field
The utility model relates to a truck scale field especially relates to truck scale counter-force calibration device installation pier.
Background
Some electronic automobile scales in China adopt the verification rule of JJJG 118-2015 during verification, and a 'reaction calibration device (cantilever beam) fixed concrete connection pier' needs to be manufactured in construction. Fig. 1 shows a commonly used pier pre-embedded plate structure, which is composed of a foundation plate B and pre-embedded bolts C. 8 step holes D of 40mm are processed on the foundation plate and used for welding the embedded bolts. And 9M 24 threaded holes are also machined for installing and fixing the reaction force calibration device. The foundation plate and 8 pieces of 25# deformed steel bars with the length of 500mm are connected in a welding mode. According to the requirements, the foundation plate and the embedded bolts need to be galvanized, if a mode of welding firstly and then galvanizing is adopted, each plate is provided with 8 embedded bolts of 500mm, so that a galvanizing pool needs to have enough capacity, and the galvanizing efficiency is extremely low; if the mode of firstly galvanizing and then welding is adopted, not only is the welding caused by the splash defect, but also the welding strength is difficult to ensure, and the original galvanized layer is damaged, so that the requirement of the initial anticorrosion treatment cannot be met. It is known that manufacturers currently take remedial measures after welding by using self-painting. Therefore, it is a point of extreme contradiction in the processing technology. The foundation plate in traditional abutment is because need set up the screw hole and fix counter-force calibration device, consequently in order to reach sufficient intensity, this foundation plate is thicker, and processing, transport, installation are all inconvenient.
SUMMERY OF THE UTILITY MODEL
In order to solve the not enough among the prior art, provide a simple structure, pre-buried board and reinforced concrete foundation firm in connection, the swift convenient counter-force calibration device installation pier of counter-force calibration device installation, the utility model discloses the technical scheme who adopts is:
the utility model provides a vehicle weighing apparatus load appearance counter-force calibration device installation pier, includes reinforced concrete basis top be equipped with the built-in plate on seted up a set of mounting hole the built-in plate lean on reinforced concrete basis one side welding have a set of thickening nut, each thickening nut and each mounting hole position corresponding, each thickening nut on threaded connection have a buried steel bar in advance, each thickening nut all reserve the screw hole that has the fixed counter-force calibration device bolt of connection, at each buried steel bar in advance and thickening nut junction be equipped with the screw thread, at each buried steel bar in advance screw thread department be equipped with the back nut of tight on thickening nut in top, buried steel bar in advance welded fastening on reinforced concrete basis steel bar component.
Furthermore, the thickness of the thickened nut is at least 60mm, and the depth of a threaded hole of the bolt of the thickened nut, which is connected with the fixed counter-force calibration device, is at least 30 mm.
Furthermore, each embedded steel bar is L-shaped.
Furthermore, slurry turning holes are formed in the embedded plates.
The embedded plate thickness is less in this pier, only needs to open the through-hole on the embedded plate, through at embedded plate through-hole position welding thickening nut, just can realize setting up the screw hole and install counter-force calibration device on the embedded plate to practice thrift the cost, processing is convenient, and fixes embedded bar through thickening nut, improves embedded bar installation effectiveness and installation portability.

Detailed Description
The counter-force calibration device installation abutment shown in figure 2 comprises a reinforced concrete foundation 1, a pre-embedded plate 2 is arranged at the top of the reinforced concrete foundation 1, a group of installation holes 4 are arranged on the pre-embedded plate 2 shown in figure 3, a group of thickening nuts 3 corresponding to the installation holes 4 are welded on the pre-embedded plate 2, pre-embedded steel bars 5 are connected on the thickening nuts 3, the pre-embedded steel bars 5 are connected with the thickening nuts 3 through threads, therefore, threads are arranged at the connecting ends of the pre-embedded steel bars 5 and the thickening nuts 3, in order to control the length of the pre-embedded steel bars 5 extending into the thickening nuts 3, back-tightening nuts 6 are further arranged at the threads of the pre-embedded steel bars 5, the pre-embedded steel bars 5 and the thickening nuts 3 are connected in place and then are tightly pressed against the thickening nuts 3 through the back-tightening nuts 6 to realize the positioning of the pre-embedded steel bars 5, thus, a threaded hole with a certain depth is reserved in the thickening nuts 3, in order to achieve sufficient strength requirements, the thickness of the thickened nut 3 is at least 60mm, and the depth of a threaded hole reserved for installing a bolt of the counter force calibration device is at least 30 mm. Because the mounting hole 4 needs to be exposed when the counter-force calibration device is installed, and the mounting surface of the counter-force calibration device is ensured to be flat, the thickening nut 3 should be embedded into the reinforced concrete foundation 1 when concrete is cast, and the top surface of the embedded plate 2 should be exposed out of the reinforced concrete foundation 1, in order to enhance the firmness of the embedded plate 2 in the reinforced concrete foundation 1, the embedded steel bar 5 is welded with the reinforced member 1-1 in the reinforced concrete foundation 1 as shown in fig. 4, and the embedded steel bar 5 can be bent to form an L shape to increase the anchoring force. And the embedded plate 2 is also provided with a grout turning hole for ensuring that the concrete under the embedded plate is tightly filled when the concrete is cast.
