The top protection of the steel platform is generally assembled in bulk after the Bailey overhead is completed. It is necessary to pull the protective rope first, and the workers need to position the protective net columns at high altitude, install the protective net bolts, and lay the walkway boards. Many up and down construction actions need to be completed. Before the overall protection is formed, the risk factor is high, the construction time is long, and the cost increases. Due to the inevitable gap between the steel platform and the frame, the overall effect needs to be improved after the construction is completed. Summary of the Invention

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 6 As shown, the utility model of the steel platform top protection device of the building construction machine includes a steel platform Bailey frame 1, a protection net column 2, a protection net 3, a corner auxiliary column 4, M8*110 bolts 6, M8*80 bolts 7, M8*40 bolts 8 and a walkway plate 5.

[0025] The steel platform Bailey frame 1 is connected to other Bailey frames using specially designed male and female connectors and high-strength bolts. This is fixed to the top of the crane's support columns to form a steel platform. The steel platform serves as the crane's operating and control platform and as a work platform for other teams. The protective net columns 2 are secured to the steel platform Bailey frame 1 using connecting plates and bolts. A walkway slab 5 is laid on the steel platform Bailey frame 1 and secured to the crossbeams of the platform Bailey frame. The walkway slab is protected on both sides by protective net columns 3, forming a frame. The protective net 3 is bolted between the columns. The corners of the protective net system are fully enclosed by corner auxiliary columns 4.

[0026] The utility model is designed for the top protection of the steel platform of the building construction machine. By designing a full range of protective nets 3 and protective net columns 2 and corner auxiliary columns 4 on the top, the problem of tiny gaps between the side and bottom of the steel platform protection and poor sealing is solved.

[0027] In the above embodiment, the building machine is assembled by a steel platform Bailey frame 1, which is divided into various sections. In the preliminary design, the adaptability design is carried out according to the civil engineering structure. The Bailey frame 1 is composed of various types of Bailey plates to form an integral whole.

[0028] In the above embodiment, the steel platform Bailey frame 1 needs to be segmented in advance, assembled on the ground at the initial stage of installation, connected by Bailey pins, and fixed with tension screws to form a segment. The segments are spliced into a whole and connected with Bailey pins after aerial hoisting.

[0029] In the above embodiment, a protection system needs to be set up on the top of the steel platform Bailey frame 1 to ensure the safety of construction workers. During the ground assembly period of the steel platform Bailey frame 1 system, positioning is carried out according to the detailed design drawings of each system, the positioning of the protection net column 2 is drawn, and the connecting plate is installed. If there is any conflict between the connecting plate supporting bolts and the steel platform Bailey frame 1, timely adjustment is made, and slight movement is allowed according to the design drawings.

[0030] In the above embodiment, the protective net column 2 is preliminarily installed according to the positioning, and the bottom of the protective net column 2 is connected to the steel platform Bailey frame 1 through a connecting plate and matching bolts to ensure the installation progress of the straight section. The protective net 3 with a width of 2 meters ensures the overall effect. The corner part is equipped with a matching corner auxiliary column 4 to install the non-standard protective net 3. Pay attention to the opening direction of the corner auxiliary column 4 and the matching bolts.

[0031] In the above embodiment, the connection between the steel platform Bailey frame 1 and the walkway plate 5 is fixed with hook bolts, which are fixed on the ground in advance and cannot be simply pre-tightened. This is because it is easy to slip during high-altitude operations, causing safety hazards. After the steel platform Bailey frame 1 is assembled in sections, symmetrical lifting openings are reserved on the walkway plate 5 for easy lifting.

[0032] In the above embodiment, a system consisting of a large-surface protective net column 2, a protective net 3 and a corner auxiliary column 4 formed in one step is adopted, and a local corner position is reserved. After the steel platform Bailey frame 1 is hoisted and assembled, a protective rope is pulled on the top of the steel platform for installation.

[0033] In the above embodiment, the corner auxiliary column 4 is fixed at the corner with M8*80 bolts 7 and M8*40 bolts 8. Note that the opening position of the corner auxiliary column 4 is asymmetric, and the opening side close to the edge is installed on the inner side of the Bailey frame 1.

[0034] In the above embodiment, the protective net columns 2 and the corner auxiliary columns 4 installed on the inner side of the steel platform Bailey frame 1 and the walkway plate 5 form a three-sided closed protection system close to the steel platform Bailey frame 1 and the walkway plate 5. The maximum gap is only 2 mm, which meets the requirement that small stones cannot fall and improves overall safety.

[0035] The utility model also provides a construction method for a top protective device of a steel platform of a building construction machine, comprising the following steps:

[0036] S1, when the Bailey frame on the steel platform is chorded and Bailey plates are assembled on the ground in strict accordance with the detailed drawings, the protective net columns are positioned;

[0037] S2, install the walkway plate on the steel platform Bailey frame according to the designed position of the walkway plate, and then fix the walkway plate;

[0038] S3: Install the protective net columns according to the detailed drawings, pre-tighten the bolts connecting the protective net columns and the steel platform Bailey frame, and adjust the gap between the columns and the walkway board;

[0039] S4, install the bolt connection between the protective net and the protective net column, adjust the distance between the bottom of the protective net and the walkway plate to ensure there is no gap, tighten the bolts, and pre-install the corner auxiliary columns at the corners.

[0040] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, which are all within the protection of the present invention.
