Description

Technical Field

[0001] The present invention relates to the technical field of construction trolley equipment, and in particular to a three-layered assembled underground station assembling trolley equipment. Background Art

[0002] The three-layer stacked prefabricated underground station assembly trolley equipment is an important technical equipment that has emerged in the field of underground station construction projects. With the acceleration of urbanization, the demand for underground transportation infrastructure construction has increased dramatically, and the traditional cast-in-place underground station construction faces many challenges.

[0003] In the traditional construction method, the concrete structure of the underground station is mostly cast as a whole on the construction site. This method has a long construction period because it requires a large amount of on-site formwork construction, steel bar binding, concrete pouring and maintenance work. Each process is time-consuming and labor-intensive, and the connection between the processes is limited. It is easily affected by various factors and delays in the construction period. Therefore, prefabricated components are gradually used to replace cast-in-place concrete. However, there is no targeted equipment for the installation of prefabricated concrete components. The method of relying solely on gantry crane lifting is not suitable for the installation and construction needs of prefabricated components.

[0004] To sum up, we consider designing a device that can quickly and accurately assemble prefabricated composite assembly components at the construction site of the underground station, and can verify and adjust the position, thereby effectively shortening the construction period. In view of this, we propose a three-layer composite assembly trolley equipment for underground stations. Summary of the invention

[0046] See also Figure 1-10 The present invention describes the above technical solution in detail through the following embodiments:

[0047] This implementation of the three-layer composite underground station assembly trolley equipment is as follows: Figure 1-Figure 3 The structure shown in the figure comprises a mobile base 1, on which a Figure 1 The scissor lift platform 11 shown in the figure can be lifted and lowered in the vertical direction to adjust the height; it should be noted that in this embodiment, Fig.10 Taking the construction of a three-story underground station as an example, each floor needs to use the equipment to assemble prefabricated side wall panels 101, prefabricated center columns 102, prefabricated longitudinal beams 103 and prefabricated middle plates 104, and the prefabricated top plate replaces the prefabricated middle plate 104 at the top. After the three layers at the bottom are constructed, the equipment is constructed layer by layer from bottom to top.

[0054] The working principle of the three-layer stacked assembled underground station trolley equipment of this embodiment is as follows: Fig.10 Taking the construction of the three-layer superimposed assembled underground station as an example, the bottom negative three-layer bottom plate is cast-in-place concrete, and a cup mouth is reserved for the prefabricated side wall panel 101 to be positioned and fixed; when assembling each prefabricated component, it is necessary to cooperate with the gantry crane above the foundation pit for lifting and flipping construction operations; during the construction process, the assembly section is set into four steps, first assembling the prefabricated side wall panels 101 on both sides, and then assembling the prefabricated center column 102, prefabricated longitudinal beam 103 and prefabricated middle plate 104 in sequence; other embodiments can be set up as four independent parts based on each prefabricated component, and assembled separately; specifically, the longitudinal beam support plate 3 and the clamping claw 4 installed on the moving block 8 are used to support the prefabricated longitudinal beam 103 and clamp the prefabricated center column 102 respectively, the L-shaped support plate 51 in the side wall assembly component 5 is used to support the prefabricated side wall panel 101, and the top plate 26 is used to support the prefabricated middle plate 104; the specific construction schematic diagram is shown in Fig.10 The position relationship shown in the figure can be used to assemble the prefabricated side wall panel 101 to a specific position through the L-shaped support plate 51. In order to better fix the prefabricated side wall panel 101 in other embodiments, a suction cup or a side clamp arm can be installed on the L-shaped support plate 51 to maintain the position; the clamping claw 4 and the longitudinal beam support plate 3 can sequentially complete the clamping assembly of the prefabricated center column 102 and the assembly of the prefabricated longitudinal beam 103, and finally the prefabricated middle plate 104 is assembled to the position shown in the figure through the upper scissor lift 11. Fig.10 The construction position shown is sufficient, wherein the node connection of the prefabricated components needs to be connected by pouring concrete, which part belongs to the existing construction technology; the device can realize the specific position assembly operation of four common components: prefabricated side wall panels 101, prefabricated middle panels 104, prefabricated longitudinal beams 103 and prefabricated center columns 102.

[0055] For ease of understanding, this application specifically explains how the device is applicable to Fig.10 The three-layer stacked prefabricated station is assembled and constructed as shown in the figure. Fig.10The position relationship shown includes a bottom plate, a precast side wall plate 101, a precast center column 102, a precast longitudinal beam 103 and a precast middle plate 104 for forming the station space, and a precast middle plate 104 located at the top for serving as a top plate; first, cast-in-place concrete is used to form the bottom plate, then the precast side wall plate 101 is assembled and the cast-in-place side wall is cast to complete the connection, then the precast center column 102 and the precast longitudinal beam 103 are assembled, the connection node concrete is cast, then the precast middle plate 104 is erected, and concrete is cast symmetrically at both ends of the middle plate to form a single-layer construction; with the middle plate as the basis, the single-layer construction steps are repeated from bottom to top to construct upward; when the station is constructed to the top layer, the cast-in-place top plate is cast to complete the capping; the layer-by-layer construction process can realize height adjustment based on the scissor lift 11 of the equipment, so as to meet the assembly construction requirements of precast components of different floor heights, and its adjustment process is simple and reliable, which is conducive to improving construction efficiency and construction quality.
