Description

Vertical prefabricated component seals storehouse structure

Technical Field

The utility model relates to a PC building industrialization field especially relates to a vertical prefabricated component seals storehouse structure.

Background

Public buildings such as schools and the like generally adopt an assembled integral frame structure, and beams and columns form a stress frame of the structure. The reliable connection between floor and the precast column directly influences the structural safety, and grouting sleeve connection is one of the main modes of precast column connection. The pre-buried slip casting sleeve in precast column lower part, the reinforcing bar that stretches out relative its top end face of pre-buried in the floor, when installing the precast column, cup joint the sleeve of precast column and floor pre-buried reinforcing bar, for the joint strength who ensures between precast column and the floor, leave the horizontal seam that 2cm is used for filling the mortar between precast column bottom and the floor. Through the slip casting hole slip casting that the sleeve runs through prefabricated post side, the mortar not only is connected sleeve and embedded steel, thereby will the seam fill up in addition with prefabricated post and floor reliable connection.

And sealing the bottom seam of the column before grouting to obtain the sealed cabin. Most of the currently used bin sealing methods are that a foam rod is filled around a seam, and a circle of mortar is smeared on the periphery of the foam rod. The method has obvious defects that firstly, the foam rod has no strength, and the cross section of the joint can be weakened by stretching into the joint, so that the potential safety hazard of the structure is caused; and secondly, the peripheral mortar strength often cannot bear the pressure of high-pressure grouting, the bin explosion occurs, and the subsequent treatment is troublesome. And thirdly, the sealing of the bin is long in time and low in manual efficiency. And fourthly, professional warehouse sealing personnel are required.

Chinese utility model patent CN207829155U discloses a prefabricated post slip casting seals storehouse structure, through wrapping around the seal ring in the bottom of prefabricated post all around, because prefabricated post surface unevenness has the gap between seal ring and the prefabricated post, for preventing to seal storehouse mortar and leak, need pour into the cast-in-place area of one deck mortar between the internal face of seal ring and the prefabricated post. Practice shows that the poured mortar can enter the joint, so that the cross section of the joint is weakened, and the potential safety hazard of the structure is caused. And after grouting, the mortar cast-in-place belt is fixedly connected with joint mortar, manual shoveling of the mortar cast-in-place belt is time-consuming and labor-consuming, and the joint structure is easy to damage due to improper operation.
