Abstract
A grouting sleeve structure of a shear wall is characterized in that a grouting sleeve is pre-embedded at the bottom of the shear wall, extended connecting steel bars are pre-embedded in a lower building component below the shear wall, a base slurry leveling layer is laid on the top of the lower building component, and an isolation sleeve is sleeved on the periphery of the connecting steel bars when the base slurry leveling layer is laid on the top of the lower building component; the bottom of the shear wall is connected with a mortar leveling layer of a lower building component, and the upper end of a connecting reinforcing steel bar extending out of the lower building component is inserted into a grouting sleeve pre-embedded at the bottom of the shear wall. The utility model discloses not only can guarantee that every telescopic grout is closely knit, the quality is controllable, avoids the grout extravagant, does not receive the restriction in construction site moreover.
Description
The technical field is as follows:
the utility model relates to a building engineering technical field, concretely relates to shear force wall grout sleeve structure.
Background art:
the existing grouting sleeve structure of the prefabricated shear wall and the construction process thereof mainly adopt a bin-dividing structure and a bin-dividing grouting construction process thereof, namely, a space to be grouted between the bottom of the prefabricated shear wall and a lower building component and a pre-embedded sleeve are divided into a plurality of empty bins by partition plates at intervals, during construction, the pre-embedded grouting sleeve at the bottom of the prefabricated shear wall is connected with a connecting steel bar extending out of the lower building component, and then a grouting machine is adopted to respectively grout each empty bin and the grouting sleeve. However, in the construction process, it is found that a huge and heavy grouting machine cannot be adopted for an originally not-wide construction operation surface, the sealing performance required on the periphery of the bin wall is good, otherwise, slurry leaks out, the pressure is insufficient, the grouting sleeve is difficult to be grouted compactly, meanwhile, a plurality of pre-buried grouting sleeves are arranged in an empty bin, the phenomenon that only the sleeve in grouting operation is full, and the adjacent grouting sleeves are not full can occur, the grouting quality is difficult to guarantee, and the split-bin and diffuse-grouting type construction process has the defects of large slurry waste, high construction cost and poor grouting compactness.
The utility model has the following contents:
the utility model discloses the technical problem that will solve is: the problem that above-mentioned prior art exists is solved, and a shear force wall grout sleeve structure is provided, not only can guarantee that every grout sleeve's grout is closely knit, and the quality is controllable, avoids the grout extravagant, and used instrument does not receive the restriction in construction site moreover.
The utility model adopts the technical proposal that:
a grouting sleeve is pre-buried at the bottom of a shear wall, extended connecting steel bars are pre-buried in a lower building component below the shear wall, a base mortar leveling layer is laid on the top of the lower building component, the bottom of the shear wall is connected with the base mortar leveling layer of the lower building component, and the upper ends of the extended connecting steel bars of the lower building component are inserted into the pre-buried grouting sleeve at the bottom of the shear wall.
In the technical scheme, one side of the grouting sleeve is provided with a grouting hole and a grout overflow hole, and the grouting hole is positioned below the grout overflow hole.
In the technical scheme, the mortar leveling layer of the lower building component is paved to the installation elevation of the shear wall.
In the technical scheme, the extending height of the connecting steel bars embedded in the lower building component is higher than the installation elevation of the shear wall.
In the technical scheme, when the base slurry leveling layer is paved on the top of the lower building component, the isolation sleeve is sleeved on the periphery of the connecting steel bar.
In the above technical scheme, the isolation sleeve is a PVC sleeve with a diameter of 50 mm.
The utility model discloses outstanding substantive characteristics with show the effect:
the utility model discloses the branch storehouse grout construction method after thoroughly having changed prior art shear force wall hoist and mount, because the branch storehouse grout construction method of prior art, at first be branch storehouse, divide a plurality of storehouses in the storehouse with the space between shear force wall bottom and the lower building element, reach shear force wall bottom grout sleeve grout in the storehouse again, this just needs every storehouse and outside seal durable, bear grouting pressure and do not lead to leaking, still must adopt grouting machine equipment can guarantee the closely knit of storehouse interior thick liquids during the grout, and make thick liquids can fill the pre-buried grout sleeve in shear force wall bottom, it is closely knit to guarantee grouting sleeve thick liquids to fill, because grouting machine is bulky, and shear force wall construction operation space and working face are often very limited, can not put the grouting machine. Consequently prior art's branch storehouse grout method and adoption grouting machine are not suitable for the field operation place, the utility model discloses a simple light grouting gun is in milk to every grout sleeve respectively, from the grouting hole grout of grout sleeve lower part, spills over from the excessive grout hole on grout sleeve upper portion. The grouting sleeve can ensure that the slurry in each grouting sleeve is compactly filled and has good grouting quality. And simultaneously, the utility model discloses building element top is laid a thick liquids screed-coat to shear force wall installation elevation down, and the foundation structure of this kind of a thick liquids screed-coat is favorable to reaching one step with the butt joint of shear force wall bottom, and is high-efficient, swift, of high quality, in order to prevent that a thick liquids extrusion advances grout sleeve when hoist and mount shear force wall, influences grouting quality, and it is peripheral with the connecting reinforcement that the building element stretches out under with PVC isolation sleeve cover. The utility model discloses structure and construction process have reduced because the not closely knit rework treatment that brings of grout, do not receive the construction site restriction moreover, and is of high quality, the efficiency is high.
Description of the drawings:
FIG. 1 is a schematic structural section view of the present invention;
fig. 2 is a schematic view of the external vertical surface of the present invention.
Reference numerals:
the method comprises the following steps of 1-shear wall, 2-grouting sleeve, 3-connecting steel bar, 4-lower building component cast-in-place part, 5-mortar leveling layer, 6-lower building component, 7-grout overflow hole and 8-grouting hole.
The specific implementation mode is as follows:
referring to fig. 1, in the shear wall grouting sleeve structure of the present invention, a grouting sleeve is pre-embedded at the bottom of a shear wall, a protruding connection steel bar is pre-embedded in a lower building component below the shear wall, a base mortar leveling layer is laid on the top of the lower building component, the bottom of the shear wall is connected with the base mortar leveling layer of the lower building component, and the upper end of the connection steel bar protruding from the lower building component is inserted into the pre-embedded grouting sleeve at the bottom of the shear wall; one side of the grouting sleeve is provided with a grouting hole and a grout overflow hole, and the grouting hole is positioned below the grout overflow hole; the mortar leveling layer of the lower building component is paved to the installation elevation of the shear wall; the extending height of the connecting steel bars embedded in the lower building component is higher than the installation elevation of the shear wall; when a seat slurry leveling layer is laid on the top of the lower building component, an isolation sleeve is sleeved on the periphery of the connecting steel bar; the isolation sleeve is a PVC sleeve with the diameter of 50 mm.
