Description

Technical Field

[0001] The present invention relates to the field of ceiling construction equipment, and particularly to a construction equipment and a construction method for a green decoration ceiling system of a subway station. Background Art

[0002] A ceiling refers to a kind of decoration for the top decoration of a housing living environment. Simply put, it refers to the decoration of the ceiling, which is one of the important parts of interior decoration.

[0003] The ceiling has the functions of heat preservation, heat insulation, sound insulation, and sound absorption, and is also a concealed layer for projects such as electrical, ventilation and air conditioning, communication, fire prevention, and alarm pipeline equipment.

[0004] Compared with ordinary home ceilings, the ceilings in subway stations have higher quality standards and more complex structures due to different functional requirements. It is necessary to hide complex equipment such as ventilation, fire protection, and electricity. The aluminum square tube ceiling optimizes air circulation through a hollow design. With the increase of functional components, light steel keels need to be used for support during the installation process to meet the load requirements of large-area ceilings. At the same time, the proportion of prefabricated components needs to be increased to enable rapid installation through an engineering process and reduce the on-site construction time. The invention patent with the Chinese patent application number 201910098683.1 discloses an assembled support hanger for comprehensive pipelines in a subway station and its construction method. The assembled support hanger is erected under the beam between the side walls on both sides in the subway station, and includes a cross beam, a lateral fixing arm, a fixing column, and a diagonal brace; the cross beam is horizontally arranged between the two side walls, with vertical lateral fixing arms fixedly connected above both ends, a vertical fixing column fixedly connected above the middle, and symmetric front and rear diagonal braces fixedly connected above the middle; the bottom ends of the lateral fixing arms, the bottom ends of the fixing columns, and the bottom ends of the diagonal braces are all fixedly connected to the cross beam, and each component is prefabricated and connected into a whole in the factory; the outer side of the lateral fixing arm is fixedly installed on the wall panel, and the top ends of the fixing column and the diagonal brace are fixedly installed on the beam. Each component of this invention is customized and processed in the factory, which can solve the problem of a large number of connection and fixing points between the pipeline hangers, decoration ceiling hangers and civil engineering concrete wall panels or beams in the subway station equipment system, and effectively save the pipeline installation space. The above invention mainly proposes a solution applicable to the ceiling of a subway station, but the conventional ceiling construction method is still used in its construction method without improvement. When the pipelines in the ceiling need to be replaced or maintained in the later stage according to this construction method, the ceiling needs to be disassembled, and because the pipeline extension range is large, the disassembly range correspondingly increases, resulting in a large construction area, which is very inconvenient for places with a large flow of people such as subway stations, and it is easy to cause serious congestion due to the reduction of the activity area. Summary of the Invention

[0005] Therefore, in view of the above problems, the present invention provides a construction device and a construction method for a green decorative ceiling system of a subway station, which solve the technical problems that the installation and disassembly process of the existing ceiling board is cumbersome, it takes a long time to occupy crowded activity places such as subway stations, and it is easy to cause congestion.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A construction device for a green decorative ceiling system of a subway station, including a light steel keel frame, a plurality of prefabricated ceiling board components, and an intelligent construction device that cooperates the prefabricated ceiling board components and the light steel keel frame. The light steel keel frame is fixedly connected to the indoor ceiling, and the prefabricated ceiling board components are movably connected to the light steel keel frame through functional connection pipe fittings. The prefabricated ceiling board components are aluminum plates. After the prefabricated ceiling board components are prefabricated and produced in the factory, they are matched and installed with the light steel keel frame through the intelligent construction device. The intelligent construction device realizes the transportation, lifting and installation operations of the prefabricated ceiling board components. The functional connection pipe fittings include a plurality of connecting pipes connected end to end, and adjacent two connecting pipes are connected by a combination of chain connection and magnetic connection.

[0007] Further, the light steel keel frame includes a supporting cross beam and a supporting longitudinal beam that are matched with each other. The supporting longitudinal beam is perpendicular to the horizontal plane, and the supporting cross beam is parallel to the horizontal plane. The supporting cross beam is provided with a first connection component that cooperates with the prefabricated ceiling board components.

[0008] Further, the prefabricated ceiling board components include a ceiling board head plate, a plurality of ceiling board middle plates, and a ceiling board tail plate. The ceiling board middle plates are arranged between the ceiling board head plate and the ceiling board tail plate. The ceiling board head plate, the ceiling board middle plates and the ceiling board tail plate are connected by hinges. The prefabricated ceiling board components are provided with a second connection component, and the first connection component and the first connection component are connected in cooperation.

[0009] Further, the first connection component includes a first connection plate fixedly arranged on the supporting cross beam, a first connection groove opened on the first connection plate, and a second connection groove opened on the first connection plate. The first connection plate is arranged along the length direction of the supporting cross beam. The first connection grooves are arranged at intervals on the first connection plate. The second connection groove is arranged at the upper edge of the first connection plate and is equal in length to the first connection plate.

[0010] Further, the first connection plate is inclined to the horizontal plane, and the included angle between the two is 65°-75°.

[0011] Further, the second connection component includes a second connection plate disposed on the prefabricated ceiling panel component, a third connection groove and a fourth connection groove formed in the second connection plate. The third connection groove is spaced on the second connection plate. The fourth connection groove is disposed along the upper edge of the second connection plate and has the same length as the second connection plate. The second connection plate is rotatably connected to the prefabricated ceiling panel component through a torsion spring. The second connection plate is inclined to the horizontal plane, and its inclination angle is the same as that of the first connection plate. When the prefabricated ceiling panel component is connected to the support cross beam, the first connection plate and the second connection plate are mutually attached, the first connection groove and the third connection groove are mutually attached, and the second connection groove and the fourth connection groove are mutually attached.

[0012] Further, a magnet is disposed in the fourth connection groove. When the prefabricated ceiling panel component is connected to the support cross beam, the functional connection pipe fitting is clamped in the groove formed by the second connection groove and the fourth connection groove and is attached to the groove surface of the second connection groove under the magnetic attraction of the magnet.

[0013] Further, a first dial plate and a second dial plate are rotatably disposed on the prefabricated ceiling panel component. The first dial plate and the second dial plate are oppositely disposed on both sides of the prefabricated ceiling panel component and point to the central position of the prefabricated ceiling panel component. The free ends of the first dial plate and the second dial plate are stacked on each other and inclined downward. The first dial plate and the second dial plate are metal plates.

[0014] Further, the intelligent construction equipment includes an AGV support bottom plate, a lifting support frame disposed on the AGV support bottom plate, and a mounting plate disposed on the top of the lifting support frame. Telescopic claws for clamping the prefabricated ceiling panel component are symmetrically disposed on both sides of the mounting plate. An electromagnet is disposed at the central position of the mounting plate, and the mounting plate can be deflected.

[0015] A construction method for construction equipment of a green decoration and ceiling system of a subway station includes the following steps: S1. Assembly of the prefabricated ceiling panel component: The first ceiling panel, the middle ceiling panel, and the last ceiling panel are pre-assembled in the factory. The number of the middle ceiling panels is determined according to actual needs. After the installation of the prefabricated ceiling panel component is completed, the functional connection pipe fitting is placed above the first dial plate and the second dial plate; S2. Installation of the light steel keel frame: Arrange workers to fixedly connect the support longitudinal beam in the light steel keel frame to the roof slab by using bolts, and then fixedly connect the support cross beam to the support longitudinal beam by using screws and nuts; S3. Place the prefabricated ceiling panel assembly on the rack; transport the prefabricated ceiling panel assembly through intelligent construction equipment. When the prefabricated ceiling panel assembly is transported to the corresponding position, the lifting support frame in the intelligent construction equipment rises smoothly, and the prefabricated ceiling panel assembly is placed in the support crossbeam in an installation method with one end inclined and pre-inserted, so that the first connecting plate and the second connecting plate are in contact, the first connecting groove and the third connecting groove are in contact, and the second connecting groove and the fourth connecting groove are in contact; S4. Reinforce and install the prefabricated ceiling panel assembly; energize the electromagnet in the installation plate, control the current to generate an upward magnetic force on the first deflector and the second deflector. The first deflector and the second deflector are deflected upward under the force, and the functional connecting pipe rolls into the groove formed by the second connecting groove and the fourth connecting groove and fits with the groove surface of the second connecting groove under the magnetic attraction of the magnet; S5. Dismantle the prefabricated ceiling panel assembly; control the current through the electromagnet to generate a magnetic attraction force on the first deflector and the second deflector, and then pull out the prefabricated ceiling panel assembly downward. The functional connecting pipe fitting rolls into the groove formed by the first deflector and the second deflector.

[0016] By adopting the foregoing technical solutions, the beneficial effects of the present invention are: 1. Compared with the existing ceiling installation equipment, the ceiling body and the installation equipment of the present invention are more suitable for places with a large flow of people such as shopping malls or subway stations, and can solve the technical problems that the installation and disassembly process of the existing ceiling panels is cumbersome, requires a long time to occupy crowded activity places such as subway stations, and is easy to cause congestion. Specifically: The prefabricated ceiling panels are prefabricated in a component connection manner, which includes a ceiling panel head plate, a ceiling panel middle plate, and a ceiling panel tail plate that are hinged to each other, ensuring that there is a connection relationship between each ceiling panel after installation, and the installation and disassembly efficiency can be improved during the installation and disassembly process; This is to meet the requirement that there are mostly cables in the ceiling of the subway station, and when removing the ceiling, it is usually necessary to remove the entire ceiling panel in the area for cable maintenance or replacement.

[0017] 2. In the present invention, the connection between the prefabricated ceiling panel assembly and the support crossbeam is achieved through the first connection assembly and the second connection assembly. Furthermore, the functional connection pipe fittings are used to make the connection and cooperation between the first connection assembly and the second connection assembly more compact. The first connecting plate is inclined with respect to the horizontal plane, and the inclination angle is 65°-75°. The second connecting plate has the same inclination angle as the first connecting plate, ensuring that the connection between the first connecting plate and the second connecting plate can provide initial stability under the action of the inclined plane. Furthermore, a first connection groove, a third connection groove, a second connection groove, and a fourth connection groove are correspondingly provided on the first connecting plate and the second connecting plate. The mutual clamping and cooperation of the grooves can further improve the matching degree between the prefabricated ceiling panel assembly and the support crossbeam. Since both the first connecting plate and the second connecting plate are metal plates with metal elasticity, during their installation, the first connection groove and the third connection groove, and the second connection groove and the fourth connection groove are clamped through metal elastic connection. Furthermore, the functional connection pipe fittings are clamped in the groove formed by the second connection groove and the fourth connection groove together, enabling the first connecting plate and the second connecting plate to achieve a stable connection and thus ensuring the stable cooperation between the prefabricated ceiling panel assembly and the support crossbeam.

[0018] 3. The prefabricated ceiling panel assembly in the present invention is made of aluminum plate material, which on the one hand ensures the weight of the prefabricated ceiling panel assembly, on the other hand ensures its structural strength, and at the same time can avoid metal interference with the electromagnet on the intelligent construction equipment during the installation process; the second connecting plate in the present invention is rotationally connected to the prefabricated ceiling panel assembly by a torsion spring, ensuring that when encountering a scenario that requires maintenance and the prefabricated ceiling panel assembly needs to be disassembled, it can be pulled down vertically by the intelligent construction equipment along a downward movement trajectory. At the same time, since the components in the prefabricated ceiling panel assembly are connected by hinges, during the disassembly process, it can ensure integral disassembly without falling apart, realizing complete controllability of the disassembly process and ensuring that the disassembled prefabricated ceiling panel assembly can be repeatedly installed and used without being deformed due to falling to the ground or during the disassembly process.

[0019] 4. In the present invention, when the prefabricated ceiling panel assembly is not installed, the first deflector and the second deflector are arranged opposite to each other on both sides of the prefabricated ceiling panel assembly and point to the center position of the prefabricated ceiling panel assembly. The free ends of the first deflector and the second deflector overlap each other and incline downward. At this time, the functional connecting pipe fitting is placed in the groove formed by the two. When the prefabricated ceiling panel assembly is cooperatively connected with the support cross beam through the intelligent construction equipment, magnetic control is performed by the electromagnet on the intelligent construction equipment, so that the first deflector and the second deflector are lifted upward to change their states, changing from the original downward inclination to upward inclination. The functional connecting pipe will roll to either side during the lifting process and fall into the groove jointly formed by the second connecting groove and the fourth connecting groove and be attached to the groove surface of the second connecting groove under the magnetic attraction of the magnet, thus completing the cooperative connection between the prefabricated ceiling panel assembly and the support cross beam.

[0020] 5. When performing the disassembly operation of the prefabricated ceiling panel assembly in the present invention, the prefabricated ceiling panel assembly is directly pulled downward by the electromagnetic force generated by the electromagnet on the intelligent construction equipment. When the first connecting plate and the second connecting plate are subjected to the downward traction force in the vertical direction, the functional connecting pipe will fall off again, drop into the groove formed by the first deflector and the second deflector, and then move downward together with the prefabricated ceiling panel assembly. During reinstallation, it can be reused and return to the groove jointly formed by the second connecting groove and the fourth connecting groove to strengthen the connection.

[0021] 6. The mounting plate in the intelligent construction equipment of the present invention can move obliquely during the installation process to ensure that the second connecting plate can enter the support cross beam in an inclined state and be connected to the first connecting plate.
