Description

Technical Field

[0001] This application relates to the technical field of building construction, and particularly to an assembly method and system for a lifting and unloading type slide-in modular integrated building unit. Background Art

[0002] Modular Integrated Construction (MiC) is a prefabricated building method. It manufactures independent module units (i.e., MiC units) including structures, mechanical and electrical systems, and decoration and finishing in accordance with building codes in a factory, and assembles them at the construction site through connecting components. Compared with the traditional on-site casting method of buildings, MiC has significant advantages such as high efficiency, safety, environmental protection, and sustainability, such as shortening the construction period, better quality control, less on-site labor demand, and reducing construction waste. It is particularly suitable for projects with high requirements for construction period and on-site safety and environmental protection.

[0003] Slide-in installation is a type of assembly method for MiC. On the premise that the main building structure construction is completed, the building MiC unit is transported to each floor in a horizontal side-sliding manner. This method makes the main building structure construction independent of the production and installation of the MiC module unit, making the installation of MiC more flexible. At the same time, since the MiC unit does not need to bear the main vertical and horizontal loads, the MiC can be made lighter, and this combination form can also be applied to higher-rise buildings. However, when transporting the MiC unit to the sunken slab area indoors using the slide-in installation method, it is necessary to frequently use lifting equipment to switch the moving vehicle under the MiC unit, and the operation steps are cumbersome, which in turn affects the work efficiency of the MiC assembly process.

[0056] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0057] In order to better understand the technical solutions of the present application, the following will be described in detail in conjunction with the accompanying drawings of the specification and specific embodiments.

[0058] The embodiment of the present application provides an assembly method for a hoisting and unloading type slide-in modular integrated building unit. Refer to Figure 1 , Figure 1 This is a schematic flow chart of the first embodiment of the assembly method of the hoisting and unloading type slide-in modular integrated building unit of the present application. In this embodiment, the method includes steps S10 to S30:

[0059] Step S10: Hoist and place the current module unit on the universal wheel carrier of the temporary platform, and move the current module unit through a forklift and the universal wheel carrier.

[0060] It should be noted that the method provided in this embodiment can be applied to the scenarios of indoor MiC transportation and installation, especially in the MiC installation scenario using the slide-in method. The current module unit can be a MiC unit that needs to be transported to the target assembly position for assembly.

[0061] It should be understood that during the indoor MiC transportation process, the temporary platform can be an open-air platform or an iron platform located outdoors, which is used to temporarily place the MiC unit. On this temporary platform, several universal wheel carriers can be arranged according to the specific size of the MiC unit, so that when the MiC unit is hoisted onto the temporary platform, it can be stably placed on the universal wheel carrier and then transported by the universal wheel carrier.

[0062] Among them, the universal wheel carrier can be a handling small tank vehicle or a manual forklift. Here, the small tank vehicle can be selected as an example to illustrate the universal wheel carrier in the following text.

[0063] Furthermore, in order to improve transportation safety, several pads can be placed on the temporary platform first, and after the MiC unit is hoisted to the pads, the pads are switched to small tanks through lifting equipment, thereby avoiding the danger caused by the MiC unit accidentally sliding to the ground. The lifting equipment can be a hydraulic press or a jack, etc., which is used to output pressure to lift the object. Here, a jack can be used as an example to explain the lifting equipment below.

[0064] Specifically, before lifting, the MiC installers on the floor to which the temporary platform belongs can lay out several pads on the temporary platform according to the size information of the current MiC unit; then the construction workers on the ground connect the crane's sling to the lifting ring installed on the MiC unit before leaving the factory to start lifting; when the MiC unit is lifted to the top of the temporary platform, the installers use the traction rope on the sling to make the MiC unit correspond to the pads on the table, and finally make the MiC unit descend to be stably placed on the pads; finally, a jack is used to replace the pads with a small tank, so that the MiC unit is placed on the small tank.

[0065] In addition, you can also refer to Figure 2 Explain the arrangement of pads on the temporary platform. Figure 2 The diagram below shows the layout of the temporary platform pads. Figure 2 It can be seen that according to the size information of the MiC unit, a pad can be placed at each of the four corresponding corners of the temporary platform, and the forklift can be ready on the outdoor side of the MiC unit, so that the MiC unit can be placed stably on the pad, and then the small tank vehicle can be switched.

[0066] It should also be noted that the forklift can be a powered forklift that requires a dedicated person to drive, which is different from the manual forklift. After the small tank car is replaced, the small tank car can be used as a supporting wheel, so that the forklift can push the MiC unit to move, and move the MiC unit from the temporary platform to the ground inside the building.

[0067] In the specific implementation, the forklift operator can drive the forklift, control the forklift's fork arm to enter under the MiC unit, and use the forklift as a power source and the small tank as a support to push the MiC unit off the temporary platform and into the indoor floor.

[0068] Furthermore, considering that there may be a path turn during the movement of the MiC unit, the MiC unit can be made to turn and perform other actions by adjusting the direction of the forklift.

[0069] Specifically, when the MiC unit has a steering requirement, the fork arm can be adjusted according to the steering requirement, so that the adjusted fork arm pushes the MiC to turn with the small tank car away from the forklift as the fulcrum. Figure 3 As shown, Figure 3 This is a diagram showing the example of MiC unit steering.Figure 3 In this case, the forklift can insert the forks diagonally to lift one end of the MiC unit and push the MiC unit to pivot with the other end as the fulcrum. In addition, minor steering adjustments can also be achieved simply by translating the horizontal position of the fork arms.

[0070] Step S20: When the current module unit moves to the preset track area, replace the caster vehicle with the caster vehicle in the preset track area.

[0071] It should be understood that the sunken area (Sunken area) generally refers to an area where, in building construction or engineering design, in order to meet specific functional requirements or design requirements, the structural floor surface of a certain part is lowered by a certain height. The preset track area includes several sunken tracks located at the junction of the sunken area and the floor surface around the sunken area, and the sunken height of each sunken track is the same as the sunken height of the sunken area. As Figure 4 shown, Figure 4 is a schematic diagram of the preset track area. As can be seen from Figure 4 , at the junction of the sunken area and the surrounding floor surface, two rectangular areas can be vertically extended from the surrounding floor surface according to the MiC unit transportation route to form two areas similar to tracks.

[0072] It can be understood that installers can pre-arrange small tank vehicles with the same height in the tracks. Thus, when the MiC unit moves above the preset track area, the small tank vehicle used as the power source can be directly switched to the small tank vehicle in the track area through a jack.

[0073] Step S30: Move the current module unit through the forklift and the caster vehicle in the preset track area. When the current module unit reaches the target assembly position, unload the current module unit by means of lifting and unloading.

[0074] It should be understood that when all the small tank vehicles under the MiC unit are switched to the small tank vehicles in the preset track area, at this time, the MiC unit enters the sunken area. The forklift driver can continue to use the forklift as the power source and the small tank vehicle in the track as the support to push the MiC unit to move in the sunken area until it moves to the target assembly position in the sunken area.

[0075] It can be understood that the lifting and unloading method can be a method of unloading the MiC unit using a hoisting device such as a chain hoist, which is beneficial for more precisely controlling the placement position and angle of the MiC unit and reducing the cumbersome operation of frequently switching vehicles.

[0076] In a specific implementation, when the MiC unit moves to the target assembly position, a chain hoist can be directly used to lift the MiC unit, then the small tank vehicle is removed, and then the MiC unit is lowered so that the MiC lands on the ground at the target assembly position, completing the unloading of the MiC unit.

[0077] In this embodiment, a forklift and a small tank vehicle are used to move the MiC unit on the indoor floor. When moving to the junction of the floor and the dropped panel area and above the preset track area, the switching of the small tank vehicle at the bottom of the MiC unit is quickly completed through the preset track area, enabling the MiC unit to complete the switching from the surrounding floor to the dropped panel area, and unloading is carried out by means of lifting and unloading when the MiC moves to the target assembly position. This avoids the problem of cumbersome processes caused by frequent use of weight reduction equipment and is beneficial to improving the indoor construction efficiency.

[0078] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar content as in the above-mentioned embodiment one can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 5 , Figure 5 which is a schematic flow chart of the second embodiment of the method for lifting and unloading a slid-in modular integrated building unit of the present application.

[0079] In this embodiment, in order to specifically illustrate how to switch the small tank vehicle of the MiC unit through the preset track area, before step S20, it further includes: steps S01 to S02:

[0080] Step S01: Set a number of sinking tracks at the junction of the dropped panel area and the surrounding floor of the dropped panel area according to the dimension information of the current module unit.

[0081] It should be understood that at the junction of the dropped panel area and the surrounding floor, two rectangular areas can be vertically extended from the surrounding floor according to the transportation route of the MiC unit to form an area similar to a track. The sinking height of the sinking track is the same as the sinking height of the dropped panel area, and the number of sinking tracks can be two, and the distance between the two sinking tracks does not exceed the width of the MiC unit, so as to ensure that the MiC unit can be completely placed on the small tank vehicle in the sinking track during subsequent vehicle switching.

[0082] Step S02: Place universal wheel carriers with a preset height in each of the sinking tracks, and the preset height is determined based on the height of the surrounding floor of the dropped panel area.

[0083] It should be understood that four small tank vehicles with the same preset height can be arranged at appropriate positions within the two sunken tracks. The preset height can be slightly higher than the surrounding floor surface, that is, the preset height value can be slightly higher than the absolute value of the sunken height of the sunken slab area. At the same time, the height difference between the preset height value and the surrounding floor surface should be lower than the clearance height at the bottom when the MiC unit is transported on the surrounding floor surface. Thus, it is ensured that when the MiC unit is transported to the preset track area, the two sunken tracks and the four small tank vehicles with the preset height can be located below the MiC unit.

[0084] Correspondingly, step S20 specifically includes:

[0085] Step S200: When the current module unit moves to the preset track area, switch the universal wheel carrier to a universal wheel carrier with a preset height.

[0086] It should be understood that since the small tank vehicles with the preset height are arranged within the sunken tracks and the sunken height of the sunken tracks is the same as that of the sunken slab area, when the small tank vehicles under the MiC unit are switched to the small tank vehicles with the preset height, it can be regarded that the MiC unit starts to enter the sunken slab area.

[0087] Specifically, reference can be made here Figure 6 to illustrate the switching process of the small tank vehicles in the sunken slab area. Figure 6 is a schematic diagram of the switching process of the small tank vehicles in the sunken slab area.

[0088] In Figure 6 , first, when the MiC unit moves to the preset track area at the edge of the sunken slab area, ensure that the small tank vehicles with the preset height are located below the MiC unit; then, lift the MiC unit by a jack; then remove the small tank vehicles on the surrounding floor surface that are located below the MiC unit; finally, end the lifting operation of the jack on the MiC unit, remove the jack, and place the MiC unit on the small vehicle with the preset height. Thus, the switching of the small tank vehicles on the floor surface to the small tank vehicles in the sunken slab area is completed.

[0089] After the switching is completed, moving the MiC unit along the sunken track can make the MiC unit completely enter the sunken slab area. Therefore, step S30 specifically includes:

[0090] Step S300: When the direction in which the current module unit enters the sunken slab area through the preset track area is inconsistent with the direction of the target assembly position, use a forklift as the power source and move the current module unit through the universal wheel carrier in the preset track area.

[0091] Step S300': When the direction in which the current module unit enters the lowered floor area through the preset track area is the same as the direction of the target assembly position, using a forklift as the power source, move the current module unit through the preset pulley track and the omnidirectional wheel carrier in the preset track area.

[0092] It can be understood that, in order to improve the accuracy of the final movement of the MiC unit to the target assembly position, pulley tracks can also be installed on both sides of the MiC unit's running route. Refer to Figure 7 , Figure 7 for the schematic diagram of the pulley track installation. As can be seen from Figure 7 , when the direction in which the MiC unit enters the lowered floor area is the same as the target assembly position (installation position), two pulley tracks can be pre-arranged on the floor around the lowered floor area or within the lowered floor area according to the width of the current module unit, so as to facilitate the horizontal movement of the MiC unit within the lowered floor area and make the MiC unit accurately move to the installation position.

[0093] Specifically, if the direction in which the MiC unit enters the lowered floor area is not directly facing the target assembly position, at this time, the pulley track is not needed, and the movement mode of the MiC unit within the lowered floor area is the same as the movement mode on the floor: using a forklift as the power source and a small tank vehicle as the support to push the MiC unit to move within the lowered floor area; and if the direction in which the MiC unit enters the lowered floor area is directly facing the target assembly position, two pulley tracks can be installed on the ground on both sides of the MiC unit's running route. The two pulley tracks are respectively installed on both sides of the preset track area, and their width is the same as that of the MiC unit, so as to facilitate the MiC unit to run in a straight line along the pulley track with the small tank vehicle in the track as the support under the push of the forklift, and improve the accuracy of the final arrival.

[0094] In this embodiment, by pre-arranging a sinking track with a suitable width and a suitable sinking height at the junction of the lowered floor area and the surrounding floor according to the size information of the MiC unit, and placing a small tank vehicle with a preset height in the sinking track, it is ensured that when the MiC unit moves to the preset track area, the sinking track and the small tank vehicle with the preset height can be located below the MiC unit; and by installing two pulley tracks on the floor on both sides of the MiC unit's running route, when the direction in which the MiC unit enters the lowered floor area is directly facing the target assembly position, it is convenient for the MiC unit to run in a straight line, which is beneficial to improving the assembly accuracy of the MiC unit.

[0095] Based on the first embodiment and the second embodiment of the present application, in the third embodiment of the present application, for the content that is the same as or similar to the above-mentioned first embodiment and second embodiment, reference can be made to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 8 , Figure 8 which is the schematic flowchart of the third embodiment of the assembly method of the hoisting and unloading type sliding modular integrated building unit of the present application.

[0096] In this embodiment, to accurately unload the MiC unit to the target assembly position, step S30 specifically includes steps S301 to S303:

[0097] Step S301: According to the marking line at the target assembly position, adjust the position of the current module unit by the forklift.

[0098] It should be understood that the installer can draw a marking ink line on the ground of the lowered plate area corresponding to the target assembly position in advance to indicate the unloading position. When the MiC unit is moved by the forklift and the small tank vehicle to near the marking ink line, the forklift is used for preliminary adjustment to make the MiC unit basically aligned with the marking ink line, completing the rough adjustment of the MiC unit at the installation position.

[0099] Step S302: After the current module unit is aligned with the marking line, lift the current module unit by the chain hoist.

[0100] It should be understood that the installer can pre-install four chain hoists above the target assembly position and conduct a safety inspection on them to ensure that they are firmly installed and the load-bearing capacity meets the weight requirements of the MiC unit. Similarly, connection rings can also be pre-installed at the four corners of the MiC unit for connection with the chain hoist.

[0101] In a specific implementation, when the MiC unit reaches the installation position, the installer can connect the lifting rings at the four corners of the top of the MiC unit to the chain hoist. During the connection, it is necessary to ensure firm connection, use appropriate slings and connectors, and avoid loose or detached connections. Then, the installer can operate the chain hoist to slowly lift the MiC unit to make it leave the small tank vehicle at the aforementioned preset height. And during the lifting process, it is necessary to keep the MiC unit stable and avoid its shaking or tilting.

[0102] Step S303: Remove the universal wheel carriers in the preset track area so that the current module unit is placed on several horizontal steel sheets pre-placed at the target assembly position.

[0103] It should be understood that the installer can measure according to the actual on-site space size of the target assembly position and place different numbers of steel sheets at the four corners of the target assembly position so that the MiC unit reaches the standard height and remains horizontal when it lands.

[0104] In specific implementation, after the MiC unit is lifted, the small tank vehicle at the preset height is removed from below it. When removing the vehicle, ensure that the vehicle moves smoothly to avoid collision or scratching with the MiC unit. Then, use the chain hoisting device to slowly lower the MiC unit and place it smoothly on the horizontal steel sheet. During the lowering process, closely observe the placement state of the MiC unit to ensure its accurate positioning. Finally, when the MiC unit is completely placed on the horizontal steel sheet and the installer confirms its stable support, disconnect the sling from the chain hoisting device to complete the lifting and unloading operation of the MiC unit.

[0105] Further, considering that the accuracy of the rough adjustment process is limited and the above unloading process may cause deviation between the MiC unit and the target assembly position, after step S30, it further includes steps S401 - S403:

[0106] Step S401: When the unloaded current module unit does not meet the preset alignment requirements corresponding to the target assembly position, use the hoisting equipment to adjust the unloaded current module unit until the current module unit meets the preset alignment requirements.

[0107] It should be understood that when there is an error between the landing position of the MiC unit and the target assembly position, tools such as a jack or a crowbar can be used at this time to push the bottom of the MiC unit for adjustment, so as to achieve precise adjustment of the installation position of the MiC unit.

[0108] Step S402: Connect the current module unit that meets the alignment requirements with the adjacent module unit through the connecting piece and bolts and fix it at the target assembly position through the bolts.

[0109] Step S403: When all the module units planned to be installed in the drop - slab area are completely fixed, pour the drop - slab area and the track area until they are flush with the surrounding floor of the drop - slab area.

[0110] It can be understood that after precisely adjusting the installation position of the MiC unit, the MiC unit and the ground at the target assembly position can be fixedly installed at this time.

[0111] In specific implementation, holes can be drilled in the ground and fixed with bolts, and the adjacent MiC units can also be connected by connecting piece bolts above. Finally, after all the MiC units planned to be installed in the drop - slab area are completely fixed with bolts, concrete is poured to fill the drop - slab area and the track area to be flush with the surrounding floor to complete the fixed installation of the MiC units.

[0112] In this embodiment, after the MiC unit reaches the target assembly position, before unloading the MiC unit, the installation position is roughly adjusted according to the marked ink line. Then, the MiC unit is unloaded onto the horizontal ground by means of hoisting and unloading, and then fine-tuned by tools such as jacks and crowbars, so as to ensure the precise alignment and horizontal placement of the MiC unit with the target assembly position.

[0113] It should be noted that the above examples are only for understanding the present application and do not constitute a limitation on the assembly method of the hoisting and unloading type sliding modular integrated building unit of the present application. Based on this technical concept, more forms of simple transformation are within the protection scope of the present application.
