SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the shortcoming of above-mentioned prior art, providing a location is easy, the simple precast concrete post connection structure of being under construction.
The utility model discloses a realize through following technical scheme:
a concrete precast column connecting structure comprises a structure bottom surface, a precast column and a connecting wedge, wherein a plurality of embedded steel bars extending out of the structure bottom surface are arranged at the position, connected with the precast column, on the structure bottom surface; the connecting wedges are inserted between the prefabricated column and the bottom surface of the structure from four side surfaces respectively and used for adjusting the verticality of the prefabricated column and playing a supporting role when the contact surface of the prefabricated column and the bottom surface of the structure is uneven, and the connecting wedges are not pulled out after being inserted and can also partially replace a joint layer or a soil sealing layer in a common construction process; the lower extreme of prefabricated post be equipped with the grout hole that prefabricated hole is linked together and be located the grout outlet hole top and with prefabricated hole is linked together, through to grouting the downthehole space of pouring into with filling between prefabricated post and the structure ground of grout, make the connection more firm, grout is for not having the shrink and pours into the thick liquids.
Furthermore, the connecting wedge is made of steel, and a plurality of parallel grooves which are sequentially arranged upwards at intervals along the wedge surface are formed in the wedge surface of the connecting wedge and used for sawing off the exposed part according to the actual condition after the fixing and the positioning.
Furthermore, the depth of the grooves on the connecting wedge is gradually increased along the upward direction of the wedge, so as to facilitate cutting.
Furthermore, the bottom surface of the structure is a prefabricated beam, a prefabricated column or a prefabricated base layer, and the connection between the prefabricated column and the prefabricated column, between the prefabricated column and the prefabricated beam and between the prefabricated column and the prefabricated surface layer can be realized.
Furthermore, the gap between the connecting wedges is filled with non-shrinkage grouting material. The prefabricated column and the bottom surface of the structure are sealed by a wedge and grouting material.
Above-mentioned connection structure also is applicable to and sets up prefabricated hole on the structure bottom surface, and prefabricated post lower extreme is equipped with the connection condition of embedded bar, inserts the embedded bar of prefabricated post lower extreme in the prefabricated hole on the structure bottom surface, inserts the wedge again in the junction, and all the other structure analogies are the same.
The beneficial effects of the utility model reside in that: when the prefabricated column is sleeved on the bottom surface of the structure, the connecting wedge is arranged between the prefabricated column and the bottom surface of the structure, so that the prefabricated column can be stably placed, the unstable placement caused by the unevenness of a contact surface can be avoided, meanwhile, the verticality of the prefabricated column can be adjusted by adjusting the depth of the wedge, and the stable structure is ensured; the grooves are formed in the positions of the wedges at different heights, the structure is more neat and strong in universality by sawing the exposed parts from the grooves, and the grooves can be suitable for connecting precast columns with different specifications; the arrangement of the wedge simplifies the construction process of filling the gap with the slurry and can further ensure the construction quality.
