Method embodiment:
referring to fig. 12, a block flow diagram of an installation construction method of a prefabricated balcony according to an embodiment of the present application is shown. As shown, the method comprises the steps of:
and S1, paying off the detachable mounting bracket according to the building axis and the position of the balcony to be mounted.
Specifically, according to the building axis and the balcony position, the outer contour line of the frame body is defined, and the outer contour line is marked by ink lines, so that paying-off of the detachable mounting bracket is completed.
And a positioning step S2, namely assembling the detachable mounting bracket at the paying-off position according to the paying-off position of the detachable mounting bracket, or carrying and positioning the detachable mounting bracket to the paying-off position.
Specifically, firstly, each part of the detachable mounting bracket can be carried to the mounting site according to the progress of the mounting floor, and of course, the step can also be performed before the paying-off step S1; then, according to the paying-off position of the paying-off step S1, assembling the parts of the detachable mounting bracket; in the embodiment, the fixed supporting rod 6 is fixed first and the bottom end of the anti-overturning assembly 7 is sleeved on the fixed supporting rod 6; then assembling each upright post 21, inclined strut 22 and horizontal connecting rod 23 in the detachable support frame 2; the elevation, flatness and verticality of the detachable support frame 2 are adjusted through the upright posts 21 and the support threaded rods 12, whether the position of the detachable support frame 2 is correct or not is checked, if the position of the frame body does not meet the requirement, the anti-overturning assembly 7 can be loosened, and the position of the frame body is adjusted to meet the installation requirement; and then the sliding component 4 is installed, acceptance before installation is carried out, and if the sliding component does not meet the requirement, rectification is carried out, so that the hoisting requirement before installation is met.
And step S3, lifting the balcony to be mounted above the detachable mounting bracket, adjusting the position of the balcony to be mounted until the lifting position is preset, and placing the balcony to be mounted on a sliding component of the detachable mounting bracket.
Specifically, firstly, a tower crane can be used for lifting the balcony 8 to be installed above an installation working surface such as a detachable installation bracket; then, the position of the balcony to be installed is adjusted through the tower crane until reaching a preset lifting position, the left and right positions of the preset lifting position are controlled within 30mm from the preset installation position, and the preset lifting position is positioned at the front side of the preset installation position by 100-150mm, so that the steel beam at the rear part of the balcony to be installed is inserted into the in-place beam. Finally, the balcony 8 to be mounted is slowly put on the steel spacer 42, the stability of the balcony 8 to be mounted on the detachable mounting bracket is checked, after confirming safety, unhooking is performed, and other components such as other balconies are arranged for lifting by the tower crane, so as to improve the mounting progress.
And step S4, the balcony to be installed is pushed to enable the balcony to be installed and the sliding component to move linearly synchronously until the balcony to be installed moves to a preset installation position.
Specifically, because the steel bars of the balcony 8 to be installed are required to be prevented from colliding with the frame beam steel bars, the left and right positions of the balcony 8 to be installed are adjusted firstly, and after the position standard required by design and specification is reached, namely, the front position of the preset installation position is reached, the balcony 8 to be installed is moved back and forth, the frame beam steel bars are adjusted in advance according to the steel bar design diagram of the balcony 8 to be installed, the steel bar collision is avoided, and only the balcony 8 to be installed is required to be inserted into the design position of the frame beam through linear movement, so that the balcony 8 to be installed is shifted to the preset installation position. According to the application, the tetrafluoro slide plate is adopted, so that the pushing force required by 3t balcony translation is less than 1000N, the crane can be manually moved without lifting through the crane, the service time of the crane can be saved, and the crane can lift other components.
And S5, fixing the balcony, namely, by adjusting the height of the supporting and pressing mechanism, enabling the supporting and pressing mechanism to be in pressing contact with the balcony to be installed, replacing the sliding component to fixedly support the balcony to be installed, and dismantling the sliding component arranged below the balcony to be installed so as to realize the recycling of the sliding component.
Specifically, first, the top 6 support pressing mechanisms 5 at the top of the rotatable bracket are pressed against the balcony 8 to be mounted with the top ends of the support pressing mechanisms 5. Then, the nut is rotated to unlock the fixed end wedge 421 and the movable end wedge 422, and the movable end wedge 422 moves downward under the action of gravity. Finally, the sliding support 41 and the steel spacer 42 are removed so that the sliding assembly 4 can be installed on the next balcony.
And S6, dismantling parts of the detachable mounting bracket after the connection part of the balcony to be mounted is poured and reaches preset strength, so as to realize the recycling of the detachable mounting bracket.
Specifically, after the connection part of the balcony to be installed is poured and reaches preset strength, the connection part is generally removed after the components are firstly installed, and the components which are later installed are firstly removed contrary to the installation of the detachable installation bracket; the detachable support frame 2 and the anti-overturning assembly 7 are removed in sequence. The preset intensity may be determined according to actual situations, and is not limited in this embodiment.
In summary, according to the installation construction method of the prefabricated balcony provided by the embodiment, the balcony 8 to be installed can be lifted and installed on the detachable installation support, and the balcony 8 to be installed is driven to perform position adjustment in the horizontal direction through position adjustment of the sliding component 4 in the horizontal direction, so that the balcony 8 to be installed slides to a preset installation position; after the position of the balcony 8 to be installed is adjusted to the preset installation position, the support jacking mechanism 5 is in jacking contact with the balcony 8 to be installed, the sliding component 4 is replaced to fixedly support the balcony 8 to be installed, so that the sliding component 4 is removed, displacement of the balcony 8 to be installed can be avoided, especially, the position of the balcony 8 to be installed is inaccurate compared with that caused by the fact that the sliding component 4 is likely to be displaced during subsequent concrete pouring, therefore, the displacement of the balcony 8 to be installed can be avoided by the support jacking mechanism 5, the installation position precision of the balcony 8 to be installed is ensured, the installation quality effect is improved, the tower crane can be quickly unhooked to hoist other components, the installation efficiency is improved, the installation progress is accelerated, and the labor intensity is reduced.
