Description

Technical Field

[0001] The invention relates to the technical field of building decoration, and in particular to a construction process for stone decorative columns outside a glass curtain wall. Background Art

[0002] In order to improve the aesthetics of buildings, decorative columns are installed outside the glass curtain walls of some large venues and exhibition halls to increase the decorative effect. These columns are mainly used for decorative effects and do not impose gravity loads on the buildings. Generally, stone decorative columns use hollow arc stone slabs, and a core is installed inside to support the hollow arc stone slabs. The hollow stone columns are then mounted on the outside of the core to form decorative columns.

[0003] After searching, the Chinese patent application number CN202111550437.9 discloses an integral spatial stone decorative column and its installation method, including an embedded plate, a bottom core column, a plurality of upper core columns, and a plurality of decorative sleeve sections. The bottom core column is vertically fixed on the embedded plate, and a bayonet is provided at the upper end of the bottom core column. However, when installing the decorative column, the above technical solution requires that the hollow arc stone slab be lifted by a lifting equipment, and the installer needs to use a scaffolding or other lifting equipment to move to the side of the lifted arc stone slab before the arc stone slab can be installed on the core body. Due to the limited construction area of ​​the outer wall of the glass curtain wall, it becomes very troublesome to use multiple lifting equipment or set up scaffolding. Therefore, it is impossible to lift the arc stone slab and lift the installer to the installation area to install the decorative column at the same time using only one set of lifting equipment, resulting in low construction efficiency of the decorative column. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a construction process for stone decorative columns outside a glass curtain wall.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A construction process for a glass curtain wall exterior stone decorative column comprises the following steps: S1: The staff first installs the fixing seat at the bottom of the supporting core at the corresponding position through bolts, and then places the multiple arc stone slabs to be installed on the installation plate; S2: The worker climbs onto the hoisting mechanism set on the installation plate, then hangs the arc stone slab on the hoisting mechanism, and then controls the hoisting mechanism to move the arc stone slab and the worker upwards by a corresponding distance; S3: The staff fixes the fixing plate on one side of the arc stone slab after hoisting to the corresponding height to the supporting plate with bolts, then controls the hoisting mechanism to move downward and reset, and then repeats the above steps to complete the installation of the decorative column.

[0006] Preferably: the lifting mechanism includes a support frame, a winch, a mounting platform, a guide rod, an electric slide rail, an electric hydraulic telescopic rod, a push-pull plate, a connecting block, a splint, a traction buckle, a guide frame and a control button.

[0007] Furthermore: the electric hydraulic telescopic rod and the winch are electrically connected to the control button respectively, and a plurality of universal wheels are fixed to the outer wall at the bottom of the mounting plate.

[0008] Further preferably, a guide cylinder is arranged on the outer wall of the mounting plate, a movable rod is slidably connected to the inner wall of the guide cylinder, a group of sleeves are connected to the outer wall of the movable rod via a hinge, and a buckle is fixed to the outer wall of the sleeve.

[0009] As a preferred embodiment of the present invention: a group of second support frames are slidably connected to the inner wall of the mounting platform, a group of second rack plates are fixed to the outer wall of one side of the second support frame, the outer wall of the mounting platform is rotatably connected to a rotating shaft, a first gear and a group of second gears are fixed to the outer wall of the rotating shaft, the second gear is meshingly connected to the second rack plate, and the first rack plates are respectively fixed to the outer walls on both sides of the support frame, and the first gear is meshingly connected to the first rack plate.

[0010] As a further preferred embodiment of the present invention: a first ladder is fixed to an outer wall of the mounting platform, a second guardrail is fixed to an outer wall of the second support frame, a third ladder is fixed to an outer wall of the second guardrail, and a first guardrail is fixed to an outer wall of the mounting platform.

[0011] As a further solution of the present invention: limiting blocks are respectively fixed to the outer walls on both sides of the second support frame.

[0012] On the basis of the above-mentioned scheme: a guide groove is opened on the outer wall of the installation plate, and the clamping plate is slidably connected to the inner wall of the guide groove.

[0013] Preferably, based on the above solution: a first support frame is fixed to the inner wall of the installation platform, and a second ladder is fixed to the inner wall of one side of the first support frame.

[0014] Based on the above solution, it is further preferred that: a wear-resistant pad is provided on the inner wall of the collar.

[0015] The beneficial effects of the present invention are: 1. The staff adjusts the direction of the arc stone slab by turning the push-pull plate, and then pushes the electric slide rail as a whole to move forward under the guidance of the guide frame and the guide rod, so as to move the arc stone slab to the corresponding installation position on one side of the support core. Then the staff can fix the fixing plate on one side of the arc stone slab to the supporting plate on the outer wall of the support core by bolts, thereby completing the installation and fixation of the arc stone slab, and allowing the lifting mechanism to stably lift the arc stone slab and the staff to the corresponding installation height, thereby improving the installation efficiency of the decorative column while reducing the space occupied by the decorative column installation construction equipment.

[0016] 2. The staff moves the lifting mechanism to one side of the support core through the universal wheel at the bottom of the mounting plate, then puts the ring on the outer wall of the support core, and fixes the two rings together through the buckle, and limits the lifting mechanism as a whole around the support core through the ring and the movable rod. When the mounting plate moves back and forth, the movable rod will slide back and forth on the inner wall of the guide cylinder to guide the mounting plate as a whole when it moves back and forth.

[0017] 3. When the installation platform moves upward, it will drive the rotating shaft connected to the outer wall to move upward, and drive the first gear on the outer wall of the rotating shaft to move upward. When the first gear moves upward, it will drive the rotating shaft to rotate through the meshing first rack plate, and drive a group of second gears on the outer wall of the rotating shaft to rotate. When the second gear rotates, it will drive the second support frame meshing with the outer wall to move downward, pushing the second support frame as a whole to move downward on the inner wall of the installation platform. When the first gear moves upward out of the first rack plate, the second support frame as a whole will also drop to the lowest position. At this time, the staff can stand inside the lowered second support frame to install the arc stone slab that falls at the bottom of the electric hydraulic telescopic rod.

[0018] 4. When the installation platform moves downward and resets, the first gear will rotate in the opposite direction driven by the first rack plate, thereby driving the second support frame to move upward and reset through the second gear, thereby preventing the second support frame from colliding with the multiple arc stone slabs placed at the bottom when following the installation platform to descend.

[0019] 5. The guide frame can limit the rising height of the second support frame. When the second support frame drops to the lowest height, the limit blocks on both sides of the second support frame will abut against the outer wall of the installation platform, thereby limiting the second support frame and supporting the second support frame as a whole.
