Description

Technical Field

[0001] The invention relates to a method for constructing an assembled composite plate, and belongs to the technical field of composite plate construction. Background Art

[0002] The construction of composite slabs combined with aluminum formwork can improve the efficiency of building floor construction.

[0003] After the prefabrication of the composite panel in the prefabricated plant is completed, it needs to be hoisted to the corresponding position of the aluminum mold after being transported to the construction site (see Chinese Patent Publication No. CN118728057A); and after the composite panel is hoisted to the corresponding position above the aluminum mold, when the tower crane instantly lowers the composite panel at a certain height distance from the aluminum mold, there will be a problem of strong impact docking installation with the aluminum mold, and it cannot be displaced and adjusted for alignment after lowering. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a method for constructing an assembled composite slab.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a method for constructing an assembled composite slab, comprising:

[0007] After the composite panels are aligned on top of the aluminum formwork, the composite panels can be adjusted and installed without strong impact.

[0008] The construction process includes three steps of aluminum formwork erection, composite board hoisting preparation and composite board hoisting.

[0009] The steps of setting up the aluminum mold are as follows: the aluminum mold is supported by a support rod, a mounting seat can be fixed on the aluminum mold, a telescopic part A and a telescopic part B are fixedly installed on the mounting seat, a universal ball that can roll and rotate is installed on the top of the telescopic part A, and an elastic pad that provides buffering is fixed on the top of the telescopic part B.

[0010] The preparation steps for hoisting the composite plate are as follows: the plug-in holes of the protective plate are plugged into the reserved steel bars so that the reserved steel bars are completely inside the plug-in holes of the protective plate and are not exposed; the baffles on the protective plate are rotated and erected; the baffles are relatively fixed to each other by binding straps; the four baffles protect the four sides of the composite plate, presenting a protective structure in the state of hoisting the composite plate.

[0011] The steps of hoisting the composite plate are as follows: the tower crane hoists the composite plate from the construction site through a hoisting chain, and then rotates it to the corresponding position above the aluminum mold, and the tower crane lowers the composite plate. When the composite plate is lowered to a point where the construction workers can reach and operate it, the reserved steel bar body is in the plug hole of the protective plate and is not exposed and does not extend out;

[0012] The composite plate continues to be lowered, and the telescopic member B with the elastic pad rises above the aluminum mold. The bottom of the composite plate contacts the elastic pad higher than the aluminum mold. The bottom of the composite plate is buffered and lowered on multiple elastic pads. The lifting chain and protective plate are removed, and the telescopic member A with the universal ball rises to press the composite plate, so that the composite plate and the elastic pad are out of contact. The composite plate is rolled and adjusted on the universal ball. After adjusting the alignment of the reserved steel bars of the adjacent composite plates, the telescopic member A with the universal ball and the composite plate descends until the composite plate contacts the universal ball and the elastic pad, presenting a support structure with adjustable alignment after the composite plate is placed; then the telescopic member A with the universal ball continues to descend and separates from the bottom surface of the composite plate until the elastic pad is supported by the composite plate. At this time, the universal ball is lower than the aluminum mold, and then the telescopic member B is controlled to slowly descend with the elastic pad, so that the composite plate and the aluminum mold are docked and installed without strong impact; the mounting seat with the telescopic member A and the telescopic member B are removed from the aluminum mold.

[0013] The support structure of the stacked plate, which can be adjusted to the position after being placed, comprises:

[0014] Mounting seat;

[0015] Telescopic member A and telescopic member B are fixedly mounted on the mounting base;

[0016] A universal ball that can roll and rotate is installed on the top of the telescopic member A, and an elastic pad that provides buffering is fixed on the top of the telescopic member B. The universal ball and the elastic pad are in contact with and supported by a superimposed plate.

[0017] The protective structure in the state of hoisting the composite plate includes:

[0018] The four sides of the composite plate are reserved for fixing reserved steel bars, and the protective plate is provided with blind holes; the blind holes of the protective plate are plugged into the reserved steel bars of the composite plate, and the reserved steel bars are in the blind holes without being exposed or extending out.

[0019] A baffle is rotatably hinged on the protective plate, and the baffle can be rotated inward and outward on the protective plate to open; the baffles are relatively tightened and bound in opposite directions by straps.

[0020] The beneficial effect of the present invention is that when the telescopic member A descends with the universal ball and separates from the bottom surface of the superimposed plate, the elastic pad and the superimposed plate are supported at this time, and the universal ball is lower than the aluminum mold; then the telescopic member B is controlled to slowly descend with the elastic pad to be lower than the top surface of the aluminum mold, so that the superimposed plate can be butt-jointed with the aluminum mold without strong impact under the support of the elastic pad, which solves the problem of butt-jointed installation with strong impact with the aluminum mold when the superimposed plate is instantly lowered at a certain height distance from the aluminum mold.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0028] like Figures 1 to 5 shown.

[0029] A method for constructing an assembled composite panel in the present application includes the following steps.

[0030] Step one, setting up the aluminum mold: the aluminum mold 1 is set up by supporting the support rod 2, and the top supporting point of the support rod 2 is on the cross of the aluminum mold. An L-shaped mounting seat 11 is fixed on the aluminum mold 1, and a telescopic part A12 and a telescopic part B13 are installed on the mounting seat 11. A rolling and rotatable universal ball 14 is installed on the top of the telescopic part A12, and an elastic pad 15 for providing buffering is fixed on the top of the telescopic part B13. Multiple universal balls 14 can provide multi-point rolling support for the composite plate 3 in the later stage, and multiple elastic pads 15 can provide damping buffering when the composite plate 3 is lowered.

[0031] Step 2, preparation for hoisting the composite plate: install a protective plate 4 made of plastic foam board at the end of the composite plate 3, and connect the plug-in hole 41 of the protective plate 4 with the reserved steel bar body 31, so that the reserved steel bar body 31 is completely in the plug-in hole 41 of the protective plate 4 and is not exposed. The baffle 42 made of plastic foam board on the protective plate 4 is rotated and erected, and the baffles 42 are relatively fixed by binding straps 43. The four baffles 42 protect the four sides of the composite plate 3. At this time, a protective structure in the state of hoisting the composite plate is presented. At this time, uncleaned debris on the composite plate 3 can be limited and protected by the four baffles 42 to prevent debris from falling from high altitude during the subsequent hoisting; the lifting chain 5 is fixedly connected to the composite plate 3.

[0032] Step 3: Hoisting of the composite plate: The tower crane lifts the composite plate 3 from the construction site through the lifting chain 5, and then rotates it to the corresponding position above the aluminum mold 1. The tower crane lowers the composite plate 3. When the composite plate 3 is lowered to a point where the construction workers can reach and operate it, the reserved steel bar body 31 is in the plug hole 41 of the protective plate 4 and is not exposed and does not extend out;

[0033] The composite plate 3 continues to be lowered, and the telescopic member B13 with the elastic pad 15 rises above the aluminum mold 1. The bottom of the composite plate 3 contacts the elastic pad 15 higher than the aluminum mold 1. The bottom of the composite plate 3 is buffered and lowered on multiple elastic pads 15. The lifting chain 5 and the protective plate 4 are removed. The telescopic member A12 with the universal ball 14 rises and presses against the composite plate 3, so that the composite plate 3 and the elastic pad 15 are out of contact. The composite plate 3 is rolled and adjusted on the universal ball 14. After adjusting the alignment of the reserved steel bars 31 of the adjacent composite plates 3, the telescopic member A12 with the universal ball 14, The superimposed plate 3 descends until it contacts the universal ball 14 and the elastic pad 15, presenting a support structure in which the superimposed plate can be adjusted after being placed; then the telescopic member A12 continues to descend with the universal ball 14 and separates from the bottom surface of the superimposed plate 3 until the elastic pad 15 supports the superimposed plate 3. At this time, the universal ball 14 is lower than the aluminum mold 1, and then the telescopic member B13 is controlled to slowly descend with the elastic pad 15, so that the superimposed plate 3 and the aluminum mold 1 are docked and installed without strong impact; the mounting seat 11 is removed from the aluminum mold 1 with the telescopic members A12 and B13.

[0034] Repeat steps 2 and 3 to install multiple laminated panels 3 on the aluminum mold 1.

[0035] The above-mentioned support structure of the laminated plate capable of adjusting the alignment after placement comprises:

[0036] A mounting base 11 is used to be detachably fixed on the aluminum mold 1 by bolts or the like, and a retractable telescopic part A12 and a telescopic part B13 are fixed on the mounting base 11. A universal ball 14 that can roll and rotate is installed on the top of the telescopic part A12, and an elastic pad 15 for providing buffering is fixed on the top of the telescopic part B13. The universal ball 14 and the elastic pad 15 contact and support the composite plate 3.

[0037] When the telescopic member A12 descends with the universal ball 14 and separates from the bottom surface of the superimposed plate 3, the elastic pad 15 is now supported by the superimposed plate 3, and the universal ball 14 is lower than the aluminum mold 1; then the telescopic member B13 is controlled to slowly descend with the elastic pad 15 to be lower than the top surface of the aluminum mold 1, so that the superimposed plate 3 can be butt-jointed with the aluminum mold 1 without strong impact under the support of the elastic pad 15, thereby solving the problem of butt-jointed installation with strong impact with the aluminum mold when the superimposed plate is instantly lowered at a certain height distance from the aluminum mold.

[0038] The protective structure in the state of hoisting the composite plate comprises:

[0039] The four sides of the composite plate 3 are reserved with reserved steel bars 31 fixed thereon, and the protective plate 4 is provided with plug holes 41, and the number of the protective plates 4 is four and corresponds to the four sides of the composite plate 3; the plug holes 41 of the protective plate 4 are plugged into the reserved steel bars 31 of the composite plate 3, and at this time, the reserved steel bars 31 are in the plug holes 41 and are not exposed and are not in a protruding state.

[0040] When the composite plate 3 is hoisted to the space above the aluminum formwork 1 for the construction workers to touch and operate, the reserved steel bar body 31 is in the plug hole 41 of the protective plate 4 and is not exposed and is not in an extended state, thus solving the problem that the reserved steel bar body in the extended state poses a safety hazard to the construction workers.

[0041] The protective plate 4 is rotatably hinged with a baffle 42 , which can be rotated inward and outward on the protective plate 4 to open; the baffles 42 are relatively tightened and bound in opposite directions by straps 43 .
