Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a construction method for integrally lifting a steel grid, a truss, and electromechanical facilities. Background Art

[0002] After the grid and trusses are assembled, they are lifted to the designed position, and then the electrical trough boxes, conduits, cables are laid, and lamps are installed and powered on for testing. The trough boxes and conduits are fixed in the grid. In the current existing technology, the mechanical and electrical engineering work is carried out after the grid is lifted. The connections between the trough boxes and conduits are fixed without deformation. After the grid and enclosure projects are completed, the grid will deflect again under its own weight, and the trough boxes and conduits that are not fixed without deformation will also deform as the grid deflects. Summary of the Invention

[0003] In view of this, the object of the present invention is to provide a method for integrally lifting a steel grid, a truss and electromechanical facilities.

[0004] The invention provides a method for integrally lifting the steel grid, trusses, and electromechanical facilities using the following technical solutions:

[0005] A method for integrally lifting a steel grid, trusses, and electromechanical facilities comprises a truss and a grid, wherein the lowest elevation of the truss is lower than the lowest elevation of the grid. The method comprises the following steps:

[0006] S1. Set up supports on the foundation ground, assemble the steel balls and rods on the supports in sequence according to the construction drawings to form a unit grid, and simultaneously measure the arch elevation and unit size to ensure they meet the requirements of the specifications;

[0007] S2. When the grid is about to be completed and the trusses are assembled, the mechanical and electrical engineering construction begins;

[0008] S3. Since the first truss level is lower than the grid, the steel balls and rods for assembling the first truss level are pre-lifted to a certain height. The steel balls and rods are then lifted to the appropriate height to install the lamps and assemble the first truss level. The lifting system uses a hydraulic lifter and computer-controlled synchronous lifting. When the lifting reaches the designated position, the lifting power and hydraulic oil valve are turned off, and support columns are installed on the four sides of the grid.

[0009] S4. The grid, trusses of different heights and electromechanical components are hoisted as a whole. The hydraulic lifting is controlled by a computer to move back and forth. When the whole structure is hoisted to a suitable position, the enclosure structure is installed and unloaded. After all load construction is completed, the supports and independent columns are fixed. At the same time, each side of the grid is reliably connected to the grounding protection body.

[0010] Furthermore, in step S2, the electromechanical engineering construction includes the construction of a trough box module and a conduit module. The trough box module includes a trough box and a mounting bracket arranged on a grid. The mounting bracket is provided with a guide angle steel for installing the trough box. A grounding wire is provided at a position 20 to 30 meters between the trough box and the guide angle steel. Grounding wires are provided at the starting and ending ends of the guide angle steel to connect with the protective conductor.

[0014] Furthermore, the fixing assembly includes a lower pressure plate pressed on the top cover of the trough box, two anti-deformation plates symmetrically arranged on the lower pressure plate and a spring arranged between the two anti-deformation plates, and the top of the anti-deformation plate and the spring are arranged at the bottom of the door-type frame top rod.

[0015] Furthermore, the catheter module includes a catheter and a catheter bracket installed on a grid. A grounding wire is provided between the catheter and the catheter bracket, and the grounding wire can be extended and retracted with the catheter. The lamp is installed on the catheter bracket, and the catheter is connected to the trough box and a grounding wire is provided. The wires in the trough box are connected to the lamp through the catheter.

[0016] Furthermore, a sliding sleeve is provided on the catheter support, and the catheter passes through the sliding sleeve and can move inside the sliding sleeve.

[0017] Furthermore, the catheter support is provided with a fixing pipe clamp for fixing the catheter.

[0018] Furthermore, a hose is provided at the end of the conduit away from the trough box, the hose is connected to the lamp, and the wires in the trough box are connected to the lamp through the conduit and the hose.

[0019] In summary, the present invention has at least one of the following beneficial effects: the electromechanical work is completed synchronously when the grid is assembled, the trough box and the conduit are installed in a deformable sliding and fixed manner, the trough box and the conduit can slide freely and will not loosen when the grid is wound under load, and has reliable stability and ductility.
