Description

Technical Field

[0001] The utility model belongs to the technical field of building construction equipment design, especially to the technical field of building concrete pouring construction equipment design, and relates to an operation platform at the top of a tool joint for steel pipe pile construction. Background Technique

[0002] In recent years, with the improvement of China's comprehensive national strength, the construction of urban infrastructure has entered a period of rapid development. The speed and intensity of urban construction across the country have gradually increased, the volume of buildings has become larger and larger, and the number of multi-story buildings has increased sharply. The construction of modern buildings with multiple layers, large spans, heavy loads, and high seismic requirements has provided good conditions for the use of concrete-filled steel tubular columns.

[0003] The existing construction technology of steel pipe columns has approached maturity, and many papers and patents have discussed, improved, and optimized the construction of steel pipe columns. For example, in the Chinese science and technology periodical "Analysis of the Construction Technology of Steel Pipe Columns in the Cover and Excavation Reverse Construction Method of Subway Stations", the construction methods, technological requirements, and measures for the hole formation positioning and pouring of steel pipe columns are introduced, and some patents have provided some new ideas for the hole formation and verticality lowering of steel pipe columns.

[0004] Generally, a steel pipe column is assisted in lowering through a tool joint made of steel pipes. After the lowering is completed, the top is often several meters above the ground. When pouring inside the steel pipe column and removing the tool joint, it is often necessary for personnel to descend to the connection between the tool joint and the steel pipe column for the construction of the steel pipe column. There is no working surface at the top of the tool joint. Construction personnel descend into the tool joint to the connection with the steel pipe column through methods such as aerial work platforms, hanging baskets, and scaffolding. Moreover, there is no up-and-down passage inside and outside the tool joint, making it extremely difficult for personnel to go up and down, with a high safety risk and large operation difficulty. Summary of the Invention

[0005] The utility model discloses an operation platform at the top of a tool joint for steel pipe pile construction according to the deficiencies of the existing technology. The purpose of the utility model is to provide an operation platform at the top of a tool joint for steel pipe columns that is convenient for construction personnel to go up and down, safer, and has higher construction efficiency.

[0006] The utility model is realized through the following technical solutions:

[0007] An operation platform at the top of a tool joint for steel pipe pile construction, including a tool joint for mechanical steel pipe pile construction, characterized in that: the plane of the operation platform is a circular flat platform matching the circular cross-section of the tool joint, and is composed of four support platforms with fan-shaped structures equally divided along the radial direction and interconnected and fixed at the top of the tool joint; each support platform with a fan-shaped structure is a steel truss frame formed by welding, including a platform plane structure, a platform bottom card slot structure, and a platform railing.

[0008] The platform's planar structure consists of five equally spaced connecting radial beams arranged radially, an outer connecting beam, a middle connecting beam, and an inner connecting beam arranged circumferentially, and a connecting hanging plate provided on the upper plane of the inner ends of the three middle connecting radial beams; a vertically arranged platform support beam is provided below the inner end of each connecting radial beam, and a diagonal brace is provided between the lower end of the platform support beam and the outer end of the platform support beam.

[0009] The platform bottom card slot structure is composed of a platform hanging beam and a platform support beam vertically welded and fixed below the connecting hanging plate.

[0010] Furthermore, a vertical railing post is provided above the outer end of the connecting radial beam of the operating platform, and two to three layers of railings are provided between the posts.

[0011] Furthermore, a climbing ladder is suspended and fixed at the top of the inner connecting beam or the tool section of the operating platform.

[0012] Furthermore, the platform bottom card slot structure is composed of a U-shaped structure formed by welding a platform lower support beam, a hanging beam, and a connecting hanging plate. When the outer edge of the platform is stressed, the force is transmitted to the side wall of the tool section through the diagonal brace, making the platform stable when stressed.

[0013] The four fan-shaped structures supporting the platform are connected by pins. There are 4 rows of pin holes on the outermost connecting radial beam of the supporting platform, and they are fixed by pins after installation.

[0014] The operating platform of the present utility model is a split-type operating platform and climbing ladder processed by welding steel. After the steel pipe column is hoisted, it is hoisted and placed on the top of the tool section of the steel pipe column, providing a personnel operating platform for the pouring of the concrete of the steel pipe column and the disassembly of the tool section, providing an up-and-down passage and a small equipment stacking and operating platform for construction, solving the problems of up-and-down passage and operating platform during the construction of the steel pipe column, solving the safety risks such as inconvenient up-and-down movement and easy falling of personnel during the construction process, and improving the construction efficiency.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] 1. The operating platform of the present utility model is formed by welding angle steel and is fixedly connected to the top of the tool section of the steel pipe column through the bottom card slot. It can be disassembled into four parts and stacked in the construction site material stacking area during normal storage, occupying a small area.

[0017] 2. After the operating platform of the present utility model is used, it can provide an effective operating platform and up-and-down passage for the construction personnel of the steel pipe column, effectively avoiding risks such as falling and mechanical injury caused by the lack of up-and-down passage and platform during the construction process.

[0018] 3. The present utility model can be reused. After the construction of the steel pipe column is completed, the working platform can be treated as waste steel.

[0019] Using the utility model for the construction of steel pipe columns can effectively reduce safety risks, with convenient construction, low construction costs, simple processes, and can improve the overall construction efficiency. Through the application of the utility model, the construction efficiency can be improved. Description of the Drawings
