[0018] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0019] like Figure 1-3 As shown, the utility model is adaptable to the construction protection bracket of buildings with different outer contours and is used to be installed on the Bailey frame steel platform 1 of the building construction machine. It includes a track slide beam 2, a hanger pulley 3, a standard hanger 4, a hanger connector 5, a keel connector 6, a walkway keel 7, a walkway board 8, a hanger connecting rod 9, a mesh connector 10, a protective mesh 11, a template pulley 12 and a flap 13.

[0020] The building construction machine in this embodiment can be selected from the building construction machine disclosed in Chinese patent CN111219055A. The Bailey steel platform 1 of the building construction machine can provide an installation position for the track slide beam 2. The track slide beam 2 is fixed to any position of the Bailey steel platform 1 by using a clamping plate and bolts. The length of the track slide beam is determined according to the distance from the wall of the bracket system and the inward distance of the structure. The standard hanger 3 and the hanger pulley 4 are connected and fixed on the upper surface of the lower belly plate of the track slide beam 2 by a movable bolt. The hanger pulley 4 can drive the standard hanger as a whole to slide arbitrarily in the track of the track slide beam 2. After the distance is adjusted in place, the limit device of the hanger pulley 2 is installed to prevent the hanger pulley 2 from being disturbed by wind load and human factors. Limit bolts are provided at both ends of the track slide beam 2 to prevent the hanger pulley 2 from breaking through the limit device, and multi-level insurance.

[0021] The standard hangers 4 are connected and fastened with the hanger connector 5. The number of standard hangers 4 can be increased or decreased according to the different floor heights of the main structure 14 to meet the overall protection requirements on site. The keel connector 6 is fixed to the side of the standard hanger 4 with bolts. The side of the standard hanger 4 is evenly opened with holes, and different protective operating surfaces are set according to the different floor heights of the main structure 14. The hanger link 12 is installed and fastened with the keel connector 6 with bolts, and the walkway keel 7 is fixed with the keel connector 6 with a spring nut. The walkway keel 7 can be designed according to the different shapes of the main structure 14. The standard hangers 4, the hanger connector 12, and the walkway keel 7 form the frame of the frame to meet the force requirements of the frame.

[0022] The walkway board 8 uses finished steel springboards of different lengths, and is arranged vertically and connected and fastened with two parallel walkway keels 7 using self-tapping screws. The walkway board 8 has different processes according to the main structure 14, and the walkway keel 7 uses C-shaped steel without holes on the upper part, which can be bent according to the different curvatures of the main structure 14 and bent at different angles. The mesh connector 10 is installed and fastened with the groove of the lower chord of the walkway keel 7 using spring nuts. The mesh connector 10 is different from the design form of the traditional hanger attached to the suspension rod. The mesh connector 1 can be arbitrarily arranged in the groove of the walkway keel 7, and is not limited by the modulus of the suspension rod span, and can design standardized components to the greatest extent. The protective mesh 11 is connected and fastened with the mesh connector 10 using a pin shaft, which is convenient for installation and removal. A flap 13 is provided on the walkway board 8.

[0023] The walkway keel 7 can be specially designed according to the structural outer contour of the main structure during the design stage. During the process of the main structure core tube retracting, the arc segment is segmented according to the length of the walkway keel, and the track slide beam points to the center of the arc, and the segments are retracted. The straight segment pushes the hanger pulley as a whole, and the hanger pulley drives the entire frame to slowly move inward along the direction pointed by the track slide beam, so that the frame is retracted as a whole, and the retracted frame meets the wall spacing required for the main construction.

[0024] A hoist is hung at the bottom of the template pulley 12 to connect the vertical aluminum templates of the inner and outer walls of the main structure. The vertical aluminum template is moved on the track slide beam 2 through the template pulley 12 hanging point to realize the retreat and closing of the vertical template. After the first-floor vertical template is closed, the steel bars of the vertical wall are tied and poured. After the inner and outer templates of all vertical walls are retreated, they are lifted with the steel platform to tie and pour the steel bars of the upper vertical wall.

[0025] The interior of the hanger of the utility model can be used to mount various components and auxiliary equipment. The safety protection requirements under various working conditions during the entire construction stage of the building, including the inward and outward expansion of curved structure walls, the conversion of curved walls into straight walls, and large changes in the cross-sectional dimensions of standard floors, can be achieved without using curved non-standard components.

[0026] The utility model also provides a construction method of the above construction equipment, comprising the following steps:

[0027] All components of the pylon are hoisted by a tower crane. Since the pylon is assembled from scattered parts on the ground and then hoisted together, the pylon hanging rod and the walkway keel need to be laid out in advance to locate the specific position. The pylon connecting rod, joints, bolts and other scattered parts need to be hoisted to the corresponding installation area by a bucket. The pylon installation process is as follows:

[0028] On-site inspection of the bracket, prepare the pre-assembly installation site → stack the components in parts or load them into the bucket → lay out the lines to locate the position relationship between the walkway keel and the hanger → check whether the number and direction of the vertical pole holes are correct → install the connecting rod and walkway board layer by layer from bottom to top → install the facade protection net → calibrate and correct the bracket → inspection and acceptance.

[0029] 1. Install the track slide beam and the boom pulley

[0030] Insert the hanger pulley into the track slide beam; position according to the drawing, use the clamp plate to install the slide beam and the hanger connector on the lower chord of the truss, the straight structure track slide beams are parallel to each other and perpendicular to the structural surface; the arc structure track slide beams point to the center of the arc.

[0031] 2. Install standard boom

[0032] Use the movable bolts to connect the standard hanger to the hanger pulley, and then install the following three standard hangers in sequence. The standard hangers are installed and fastened with hanger connectors. Before installing the standard hangers, the keel connectors are integrated in advance, and the keel connectors and the hanger connecting rods are fastened with bolts.

[0033] 3. Install the walkway keel

[0034] According to the pre-divided keel sections, the keel is connected and installed with the keel connectors on the hanger using bolts and spring nuts.

[0035] 4. Install walkway panels and protective mesh

[0036] After the walkway keel is installed, the walkway board is laid according to the layout of the drawing and fixed to the walkway keel with self-tapping screws; while laying the walkway board, the protective net is installed on the walkway keel using the mesh connector. Finally, the bracket flap is installed.
