Description

Technical Field

[0001] The present invention relates to the technical field of aerial corridor structures, and in particular to a Bailey frame formwork platform for aerial corridors and a construction method thereof. Background Art

[0002] In the field of construction, the construction of formwork platforms for high-altitude corridors is a technical challenge. Traditional methods have problems such as low construction efficiency, high material consumption, and poor safety. In order to improve construction efficiency and safety, reduce costs, and achieve the reuse of materials, technicians have tried a variety of improvement schemes. However, these schemes generally have problems such as large amount of high-altitude operations, low material utilization, complex component connections, and difficulty in ensuring construction quality. For example, the component connection methods adopted in some schemes are not efficient enough, resulting in difficulties in installation and disassembly, affecting the construction progress. At the same time, the lack of standardized prefabricated components leads to large on-site processing volume, increasing construction costs and time. In addition, the components in traditional schemes are often non-detachable and cannot be reused, which is neither economical nor environmentally friendly. Therefore, the development of a new type of Bailey frame formwork platform for high-altitude corridors and its construction method, which can solve the above problems, improve construction efficiency and safety, reduce costs, and achieve the reuse of materials, is a technical challenge faced by those skilled in the art.

[0003] To address the above-mentioned issues, those skilled in the art have conducted extensive research and practice, attempting to improve construction efficiency and safety, reduce costs, and achieve material reuse by improving the structural design and construction methods of the formwork platform. However, existing technical solutions still have certain limitations and fail to fully meet the needs of modern building construction. Therefore, developing a new type of Bailey frame formwork platform for high-altitude corridors and its construction method to improve construction efficiency, reduce costs, ensure construction safety, and achieve material reuse has become a technical problem that needs to be solved in this field. Summary of the Invention

[0004] The present invention aims to provide a Bailey frame formwork platform for high-altitude corridors that is simple in structure, quick to install, safe, reliable, low-cost, and environmentally friendly, and to provide a construction method thereof, in order to meet the needs of modern building construction. The present invention is implemented using the following technical solutions:

[0005] A Bailey formwork platform for a high-altitude corridor, which is mainly composed of reinforced concrete corbels, double-jointed I-beam load-bearing beams, Bailey plates, connecting lattices, embedded parts, I-beam distribution beams and steel plates; the reinforced concrete corbels are arranged on both sides of the building corridor position, the reinforced concrete corbels are provided with embedded parts, the double-jointed I-beam load-bearing beams are placed on the reinforced concrete corbels, and the double-jointed I-beam load-bearing beams are detachably connected to the embedded parts; a plurality of Bailey beams are laid on the double-jointed I-beam load-bearing beams, the Bailey beams are detachably connected to the double-jointed I-beam load-bearing beams, the Bailey beams are composed of two adjacent Bailey plates detachably connected by connecting lattices, and two adjacent Bailey beams are detachably connected by connecting lattices; the Bailey plates are connected to distribution beams by bolts, and a steel plate formwork composed of a plurality of steel plates is laid on the distribution beams.

[0006] Furthermore, the embedded parts are embedded bolts, and a single reinforced concrete corbel has two embedded bolts. Positioning holes are provided at the positions corresponding to the embedded bolts on the two outer bottom wing plates of the double-jointed I-beam load-bearing beam, and the embedded bolts pass through the positioning holes to realize the positioning connection of the double-jointed I-beam load-bearing beam on the reinforced concrete corbel.

[0007] Furthermore, the top wing plates on the opposite sides of the two double-jointed I-beam load-bearing beams are provided with a plurality of Bailey holes along the length direction at intervals according to the width of the connecting stained glass windows, and the two ends of the Bailey plates are bolted together through corresponding Bailey holes.

[0008] Furthermore, the adjacent Bailey pieces and the connecting stained glass windows are detachably connected via matching latches.

[0009] Furthermore, the distribution beam is an I-shaped steel, and the upper surface of the top beam of the Bailey plate on both side edges is provided with multiple groups of mounting holes along the length direction according to the distribution beam layout spacing, and a group of mounting holes is provided with two, and connecting holes are opened at the positions corresponding to the mounting holes on the bottom plate of the distribution beam. The connecting holes and the mounting holes are connected by bolts after they correspond.

[0010] The method also includes the above-mentioned Bailey frame formwork platform construction method for the high-altitude corridor, comprising the following steps:

[0011] Step 1: Tie the steel bars of the reinforced concrete corbel according to the design drawings and position the embedded parts in the steel bars of the reinforced concrete corbel. After acceptance, seal the formwork and pour concrete, and cure until the concrete reaches the designed strength.

[0012] Step 2: Hoist the double-jointed I-beam load-bearing beams on both sides above the corresponding reinforced concrete corbels respectively, then align the double-jointed I-beam load-bearing beams with the embedded parts, and insert the embedded parts into the bottom plate of the double-jointed I-beam load-bearing beams for positioning, and lock the embedded parts and the double-jointed I-beam load-bearing beams with nuts to complete the detachable connection between the double-jointed I-beam load-bearing beams and the embedded parts;

[0013] Step 3: On the ground or on a building platform, multiple sets of mutually parallel Bailey sheets are detachably connected through connecting lattices to form multiple Bailey beams;

[0014] Step 4: After the installation of the Bailey beam is completed, the Bailey beams on both sides are hoisted between the double-jointed I-beam load-bearing beams on both sides, and the two ends of the Bailey beam are detachably connected to the double-jointed I-beam load-bearing beams on both sides by bolts;

[0015] Step 5: Hoist the remaining Bailey beams into place one by one between the installed Bailey beams on both sides according to the width of the connecting stained glass windows. Then, detachably connect the two ends of all Bailey beams to the double-jointed I-beam load-bearing beams on both sides. Then, connect all Bailey beams to form a Bailey frame through the connecting stained glass windows.

[0016] Step 6: Hoist the distribution beam onto the Bailey beam in sequence, and then fix the distribution beam to the Bailey beams on both sides with bolts;

[0017] Step 7: Hoist multiple steel plates onto the distribution beam, and then lay the steel plate formwork of the high-altitude corridor concrete bottom plate to form the high-altitude corridor Bailey frame formwork platform;

[0018] Step 8: After the high-altitude corridor concrete base plate is cured and reaches final setting, all detachable connections can be removed and the entire high-altitude corridor Bailey frame formwork platform can be dismantled in the order of its components. After dismantling, the remaining reinforced concrete brackets with embedded parts can be used as support points for other permanent equipment.

[0019] The Bailey frame formwork platform for a high-altitude corridor and the construction method thereof of the present invention have the following significant beneficial effects:

[0020] (1) The main components of the formwork platform are prefabricated in a standardized manner in the factory. Only simple bolt connection and assembly work is required on site, which makes the installation quick. The Bailey beam used for support is light in weight and high in strength. It can effectively solve the problems of high height, large material consumption, and long construction period of traditional high formwork. It also has a high reusability rate and is environmentally friendly and green.

[0021] (2) The embedded parts set on the reinforced concrete corbel adopt a structure of two embedded bolts as a group. Because the bolts and spiral holes must correspond to each other one by one, the positioning installation can be achieved by aligning all the positioning holes of the double-jointed I-beam load-bearing beam with all the embedded bolts, which greatly reduces the time for centering installation and fixing.

[0022] (3) Similarly, all components in the present invention are connected by bolts or matching pins, that is, all components have the technical effect of efficient positioning and fixing, and at the same time provide all components with the function of detachable reuse.

[0023] (4) In this construction method, all components are pre-assembled on the ground or platform. After hoisting, only simple positioning and fixing are required, which greatly reduces the workload. At the same time, since the Bailey beam is equipped with two pieces of Bailey beams that have the function of connecting with the distribution beam, the Bailey beams on both sides are hoisted into place before arranging the Bailey beams, which can reduce the technical problems of component misinstallation. At the same time, it is highly targeted and can greatly improve construction efficiency.

[0024] (5) After the support platform is used, all components can be dismantled and recycled, waiting for the next use. The reinforced concrete bracket with embedded bolts can continue to remain in its original position to serve as a fulcrum for the equipment required by the design. It can be used for two purposes, and no component is redundant. BRIEF DESCRIPTION OF THE DRAWINGS
