Description

Technical Field

[0001] This invention relates to the field of prefabricated electromechanical module construction technology, specifically a novel prefabricated electromechanical module and its construction method. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. In recent years, prefabricated buildings have attracted increasing attention due to their fast construction speed and low production costs, and they have enormous development potential in the future. However, the installation of prefabricated electromechanical modules is quite challenging. When designing prefabricated modules, 2-3 pieces of equipment, along with project pipelines and valves, are often grouped into a single module. These modules are generally large and far heavier than individual pieces of equipment, making unloading, hoisting, horizontal transport, and position and leveling adjustments very difficult. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of prefabricated electromechanical module and its construction method, which solves the problem of the difficulty in implementing prefabricated electromechanical modules during unloading, hoisting, horizontal transfer, and position and level adjustment.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A novel prefabricated electromechanical module includes a modular steel frame with a forklift opening on its lower edge, a floating platform fixed to the upper side of the lower edge of the modular steel frame for placing electromechanical equipment, a lifting corner bracket installed at the top corner of the modular steel frame for lifting operations, connecting slots at the four corners of the lower end of the modular steel frame, and multifunctional accessories for fixing to the connecting slots with bolts and for connecting to external mobile equipment; spring loading devices are provided on both sides of the floating platform for fine-tuning the position of the electromechanical equipment, and pipelines with valves are provided on the modular steel frame for placing the wiring of the electromechanical equipment.

[0006] Furthermore, the multifunctional accessory is a vertical load-bearing component welded together from a back plate, two trapezoidal side ribs, and a bottom plate. The upper end of the back plate is provided with a first connecting hole that can be connected to the connecting shuttle hole (5) by bolts, and the bottom plate is provided with a second connecting hole that can be connected to an external mobile device. The external mobile device is a omnidirectional roller, a square steel double-axis roller, or a ground tank that can move horizontally.

[0007] Furthermore, the lifting corner fittings are made of national standard 10101; and each of the four corners of the bottom surface of the modular steel frame is provided with a layer of polytetrafluoroethylene gasket.

[0008] Furthermore, the back plate, side ribs, and bottom plate are all made of steel plates with a thickness of 14mm, and the first connecting hole, the second connecting hole, and the connecting shuttle hole are all M22 type.

[0009] Furthermore, the spring loading device includes a loading base plate integrally formed with the modular steel frame, a force-bearing rib plate welded to the side of the floating platform, a water pump elastic shock absorber disposed between the force-bearing rib plate and the loading base plate, and a loading screw rod that passes through the force-bearing rib plate, the water pump elastic shock absorber, and the loading base plate and is limited at both ends by nuts; a loading spring is disposed between the nut at the upper end of the loading screw rod and the force-bearing rib plate.

[0010] Furthermore, the elastic coefficient of the loading spring is less than that of the elastic damper of the water pump, but greater than 1 / 5 of the elastic damper of the water pump.

[0011] Furthermore, it also includes a magnetic laser positioning aid that can be magnetically attached to a modular steel frame. The magnetic laser positioning aid includes a steel plate base, with strong magnets installed around the lower end of the steel plate base. A laser pointer is fixed to the steel plate base by a fixing clip.

[0012] This invention also provides a novel prefabricated electromechanical module construction method, which uses the prefabricated electromechanical module as described above and includes the following steps:

[0013] S1: Module unloading: Select tower crane, truck crane or forklift for unloading; when selecting tower crane or truck crane for unloading, use the lifting corner brackets as lifting points; when selecting forklift for unloading, use the forklift opening for forklift unloading.

[0014] S2: Module horizontal transport: Install the multi-functional accessories on the four lower corners of the modular steel frame. Select universal rollers, square steel double-axis rollers or ground tanks according to the weight of the module and connect them to the second connecting holes on the bottom plate of the multi-functional accessories. The horizontal transport of the module is achieved by moving the universal rollers, square steel double-axis rollers or ground tanks horizontally.

[0015] S3: Module horizontal position fine adjustment: After the module is transported to the target position, the magnetic laser positioning aid is attached to the four corners of the module's steel frame and adjusted in conjunction with the ground horizontal baseline to adjust the module's horizontal position;

[0016] S4: Overall adjustment of module level: Invert the multi-functional accessory and use a jack and magnetic laser positioning aid to adjust the overall level of the module; after adjustment, use shims to stabilize it.

[0017] S5: Module fixing: Use the multi-functional accessory as a module fixing component, and fix the second connecting hole on the base plate of the multi-functional accessory to the target position with anchor bolts or metal expansion bolts;

[0018] S6: Secondary fine adjustment of electromechanical equipment is achieved by adjusting the loading screw and loading spring in the spring loading device.

[0019] Furthermore, in step S4, the magnetic laser-assisted positioner works in conjunction with the vertical baseline on the ground. If the spot emitted by the laser pointer is within the vertical baseline on the ground, the part needs to be raised with the help of a hydraulic jack; if the spot is outside the vertical baseline, the part needs to be lowered with the help of a hydraulic jack.

[0020] Furthermore, in step S6, by adjusting the nut above the loading screw, the height of the shock absorber can be finely adjusted, and a load can be added to the water pump elastic shock absorber to achieve precise adjustment of the level of the entire electromechanical equipment.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) This invention achieves overall module unloading by setting up forklift openings and lifting corner fittings. After unloading, multi-functional attachments are installed at the four lower corners of the module, and the module is moved horizontally using universal rollers, square steel double-axis rollers, or ground tanks. After moving to the target position, the horizontal position is adjusted in conjunction with a magnetic laser positioning aid. After the horizontal position is adjusted, the module is fixed. After fixing, the electromechanical equipment in the module is finely adjusted again by adjusting the spring loading device. Using the prefabricated electromechanical equipment module provided by this invention for construction, whether it is module unloading, horizontal transportation, module level adjustment, or electromechanical equipment fine adjustment, it is easier to achieve, overcoming the problem of difficult module transportation in the prior art.

[0023] (2) The present invention achieves overall horizontal transport of the module by installing multi-functional accessories at the four corners of the lower end of the module, and the multi-functional accessories are provided with connection holes at the bottom to connect with universal rollers, square steel double-axis rollers or ground tanks.

[0024] (3) This invention utilizes a magnetic laser-assisted positioner to adjust the module horizontally. The laser pointer emits a spot that aligns with the vertical baseline on the ground. If the spot is within the vertical baseline, a hydraulic jack is used to raise that area; if the spot is outside the vertical baseline, a hydraulic jack is used to lower that area. This method is simple to operate, allowing for precise positioning of the module to the target location using simple operations.

[0025] (4) The present invention uses a spring loading device to fine-tune the electromechanical equipment in the module. By simply rotating the nut above the loading screw to finely adjust the height of the shock absorber and add load to the water pump elastic shock absorber, the entire electromechanical equipment can be precisely adjusted.

Detailed Implementation

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0042] like Figure 1 , 2 As shown, this invention provides a novel prefabricated electromechanical module, including a modular steel frame 1 with a forklift opening 8 on its lower frame. Preferably, the forklift opening 8 is used for unloading by forklifts, and its dimensions are 200×100mm. The forklift opening 8 is reinforced around its perimeter with 12mm steel plates welded together. A lifting corner bracket 4 for hoisting operations is provided at the top corner of the modular steel frame 1. The lifting corner bracket 4 adopts the national standard 10101 corner bracket and is used for unloading by tower cranes and truck cranes. The four lower corners of the modular steel frame 1 have connecting holes 5 for bolting to a multi-functional accessory 10; as shown... Figure 3 As shown, the multifunctional accessory 10 is made of steel plate and is a vertical load-bearing component consisting of a back plate 101, two trapezoidal side ribs 102, and a base plate 103, all with a thickness of 14mm, welded together. The back plate 101 has a first connecting hole 104 at its upper end, which can be bolted to the connecting shuttle hole 5. The base plate 103 has a second connecting hole 105, which can be connected to external mobile equipment (horizontal omnidirectional rollers, square steel double-axis rollers, or ground tanks). Preferably, the first connecting hole 104, the second connecting hole 105, and the connecting shuttle hole 5 are all M22 type, and the bolts used for connection are M20. Additionally, a layer of polytetrafluoroethylene (PTFE) gasket 7 is provided at each of the four corners of the bottom surface of the modular steel frame 1. The dimensions of the gasket 7 (L×B×δ) are 200×200×5mm, and it is bonded to the modular steel frame 1 with structural adhesive. A floating platform 9 for placing electromechanical equipment 2 is fixed on the upper side of the lower frame of the modular steel frame 1. Spring loading devices 6 for finely adjusting the position of electromechanical equipment 2 are provided on both sides of the floating platform 9. Pipelines 3 with valves for placing the wiring of electromechanical equipment 2 are provided on the modular steel frame 1.

[0043] like Figures 6-8 As shown, the electromechanical module provided in this embodiment also includes a magnetic laser positioning aid 11 that can be magnetically attracted to the modular steel frame 1. The magnetic laser positioning aid 11 includes a steel plate base 113, and strong magnets 114 are installed around the lower end of the steel plate base 113. A laser pointer 111 is fixed to the steel plate base 113 by a fixing clip 112. The fixing clip 112 is made of 0.6mm thin iron sheet and is fixed to the laser pointer 111 on the steel plate base 113 with M6 bolts. The dimensions of the steel plate base 113 (L×B×δ) are 200×100×6mm. In specific implementation, the magnetic laser positioning aid 11 is attracted to the side of the modular steel frame 1 by the strong magnets 114. The light spot emitted by the laser pointer 111 can be adjusted to adjust the horizontal position of the module by matching the ground baseline. The strong magnets 114 are N35 neodymium iron boron strong magnets and are bonded to the lower end of the steel plate base 113 with structural adhesive.

[0044] like Figure 4 , 5 As shown, the spring loading device 6 includes a loading base plate 605 integrally formed with the modular steel frame 1, a force-bearing rib plate 601 welded to the side of the floating platform 9, a water pump elastic damper 604 disposed between the force-bearing rib plate 601 and the loading base plate 605, and an M16 loading screw 603 passing through the force-bearing rib plate 601, the water pump elastic damper 604, and the loading base plate 605 and limited at both ends by nuts; a loading spring 602 is disposed between the nut at the upper end of the loading screw 603 and the force-bearing rib plate 601. The elastic coefficient of the loading spring 602 is less than the elastic coefficient of the water pump elastic damper 604, but greater than 1 / 5 of the elastic coefficient of the water pump elastic damper 604.

[0045] This embodiment also provides a novel prefabricated electromechanical module construction method, which utilizes the aforementioned prefabricated electromechanical modules for construction, including the following steps:

[0046] S1: Module unloading: Depending on the site conditions and machinery, select tower crane, truck crane or forklift for unloading; when selecting tower crane or truck crane for unloading, use the lifting corner brackets as lifting points; when selecting forklift for unloading, use the forklift opening for forklift unloading.

[0047] S2: Module Horizontal Transfer: Install the multi-functional accessories at the four lower corners of the modular steel frame. Depending on the module weight, select omnidirectional rollers, square steel double-axis rollers, or ground tanks to connect to the second connecting holes on the base plate of the multi-functional accessories. Horizontal transfer of the module is achieved by moving the omnidirectional rollers, square steel double-axis rollers, or ground tanks horizontally. A schematic diagram of the horizontal transfer principle is shown below. Figure 9 As shown in the figure, 12 is the connecting bolt and 13 is the square steel double-shaft roller.

[0048] S3: Module Horizontal Position Fine-tuning: After the module is transported to the target position, the magnetic laser positioning aid is attached to the four corners of the module's steel frame. Using the ground horizontal baseline as a guide, the module's horizontal position is adjusted. Figure 10 As shown in the attached diagram, reference numeral 14 represents the ground horizontal baseline. The magnetic laser-assisted locator, through the light spot emitted by the laser pointer, allows for direct observation of the module's horizontal error, greatly facilitating the dynamic adjustment of the module's horizontal position. The shims at the four corners of the module's bottom steel frame effectively reduce the friction between the module and the ground at the target location. During adjustment, the module's horizontal position can be easily fine-tuned using a pry bar. Furthermore, the PTFE shims have a compressive strength of 25 MPa, meeting the requirements for module shims.

[0049] S4: Overall Module Leveling Adjustment: After positioning the module horizontally, invert the multi-functional accessory, such as... Figure 11 As shown, a jack and a magnetic laser positioning aid are used to adjust the overall level of the module. If the laser pointer's spot is within the vertical baseline on the ground, the corresponding part needs to be raised using a hydraulic jack; if the spot is outside the vertical baseline, the corresponding part needs to be lowered using a hydraulic jack. After adjustment, shims are used to firmly support the module. Figure 12 , 13 As shown, the accompanying reference numerals are used.

[0050] S5: Module Fixing: After the module's planar position and levelness are adjusted, the multi-functional accessory is used as a module fixing component. The second connecting hole on the multi-functional accessory's base plate is fixed to the target position using anchor bolts or metal expansion bolts. Figure 14 As shown, the connecting holes on the modular steel frame have an adjustment range of 3cm. This adjustment range can be used to eliminate the height error of the shims when the module is horizontally adjusted, so that the multi-functional accessories can effectively fit with the surface where the target position is located.

[0051] S6: Secondary Fine Adjustment of Electromechanical Equipment: By adjusting the nut above the loading screw, the height of the shock absorber can be finely adjusted, allowing for the addition of load to the water pump's elastic shock absorber and achieving precise adjustment of the overall levelness of the electromechanical equipment. The elastic coefficient of the loading spring is less than that of the lower water pump's elastic shock absorber, but greater than 1 / 5 of the water pump's elastic shock absorber's elastic coefficient. Due to its inherent elasticity, the loading spring minimizes its impact on the water pump's elastic shock absorber's damping performance.

[0052] Because the on-site construction specifications and procedures have different requirements for the installation accuracy of prefabricated electromechanical modules and equipment, the allowable deviation of the levelness of prefabricated electromechanical modules is 1‰, and the allowable deviation of the levelness of equipment is 0.1‰. Therefore, after the overall installation of the modules is completed, the equipment needs to be adjusted for levelness a second time. In this example, step S6 can effectively perform a second fine adjustment of the levelness of the electromechanical equipment.

[0053] This invention achieves overall module unloading by setting up forklift bays and lifting corner fittings. After unloading, multi-functional attachments are installed at the four lower corners of the module, and the module is moved horizontally using omnidirectional rollers, square steel double-axis rollers, or ground tanks. Once moved to the target position, the horizontal position is adjusted in conjunction with a magnetic laser positioning aid. After horizontal adjustment, the module is fixed, and then the electromechanical equipment in the module is finely adjusted again using an adjusting spring loading device. Using the prefabricated electromechanical equipment modules provided by this invention for construction makes module unloading, horizontal transport, module leveling adjustment, and electromechanical equipment fine-tuning much easier, overcoming the problem of difficult module transport in existing technologies.

[0054] The above embodiments are merely one of the preferred embodiments of the present invention and should not be used to limit the scope of protection of the present invention. Any modifications or refinements made to the main design concept and spirit of the present invention that are not of substantial significance, but solve the same technical problem as the present invention, should be included within the scope of protection of the present invention.
