Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to an adjustable temporary support device for hoisting modular box-type houses. Background Technology

[0002] Prefabricated buildings are widely used due to their advantages such as high construction efficiency and minimal environmental impact. During their construction, modular housing units (i.e., prefabricated building modules) often require hoisting operations. During hoisting, the modules are prone to warping and deformation under the tension of the slings, so temporary support devices are needed to ensure their structural stability.

[0003] Currently, common temporary support methods often use structural steel components, with both ends directly fixed to the metal components of the module by welding. While this method provides necessary support, it has significant drawbacks: after hoisting, the support components must be cut off using methods such as gas cutting. This process is not only cumbersome and time-consuming, potentially damaging the module's surface coating or structure, and posing a safety hazard due to open flames, but the support components cannot be reused, resulting in material waste and increased construction costs.

[0004] Therefore, there is an urgent need for a temporary support device that can be quickly installed and disassembled without damaging building modules, is reusable, and can adapt to modules of different sizes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable temporary support device for hoisting modular box-type houses. This device adopts a non-welded magnetic connection method, which is convenient to assemble and disassemble, safe and reliable, and the support length is adjustable, which can meet the temporary support needs of box-type modules of different specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model proposes an adjustable temporary support device for hoisting a modular box-type house, comprising: two magnetic connecting base plates, two connectors, and a telescopically adjustable strut assembly connected between the two connectors; the two magnetic connecting base plates are symmetrically arranged and adapted to be embedded in the sides of both ends of the prefabricated building module; the two connectors are detachably magnetically connected to the two magnetic connecting base plates respectively; at least one guide rod is slidably passed through each connector, and a first positioning seat and a second positioning seat are fixedly connected to both ends of each guide rod respectively; an elastic element sleeved on the guide rod is provided between the first positioning seat and the connector, and a pushing mechanism is installed on the second positioning seat; a positioning element is provided on the end face of the first positioning seat and / or the second positioning seat facing the magnetic connecting base plate; the magnetic connecting base plate is provided with a positioning area, a magnetic adsorption area, and a weakly magnetic or non-magnetic area located next to the magnetic adsorption area, and a positioning hole that cooperates with the positioning element is opened in the positioning area.

[0007] Furthermore, the strut assembly includes a first rod and a second rod, the second rod being telescopically inserted into the first rod and selectively fixed at different positions by a first locking member to achieve length adjustment of the strut assembly.

[0008] Furthermore, the end of the second member furthest from the first member is detachably connected to one of the connectors.

[0009] Furthermore, the end of the first rod away from the second rod is detachably connected to another connector via a connecting sleeve.

[0010] Furthermore, the connecting sleeve is fixedly connected to the first rod by a second locking member, and the connecting sleeve is fixedly connected to the corresponding connecting head by a third locking member.

[0011] Furthermore, the actuating end of the pushing mechanism is fixedly provided with a pad, which is slidably sleeved on the guide rod and acts on the connector.

[0012] Furthermore, the magnetic connection substrate is a magnetic suction plate made of magnetically conductive steel.

[0013] Furthermore, the magnetic connector is a permanent magnet or an electromagnet.

[0014] Furthermore, the guide rods are two in number, arranged in parallel and spaced apart.

[0015] Furthermore, the elastic element is a compression spring.

[0016] The beneficial effects of this utility model are as follows: Rapid installation is achieved through a combination of magnetic adsorption and mechanical positioning; disassembly is accomplished quickly, effortlessly, and non-destructively using a jacking mechanism, greatly improving work efficiency and avoiding the safety risks and damage to modules caused by welding and cutting. The entire device can be completely disassembled and reused for hoisting other modules, reducing material consumption and construction costs. The length of the support rod assembly is adjustable, flexibly adapting to the temporary support needs of modular housing units of different sizes, offering good versatility. The guide rod and positioning seat structure ensures the straightness and stability of the connector movement; the cooperation between the positioning element and the positioning hole ensures the accuracy of the adsorption position; the elastic element provides auxiliary reset or pre-tightening force; and the overall connection is robust. It facilitates transportation and storage, and also allows for convenient partial replacement or repair in case of damage. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-3 The diagram illustrates an adjustable temporary support device for hoisting modular prefabricated houses. It is primarily used to provide temporary lateral support during the hoisting of prefabricated building modules (such as prefabricated house units) to prevent warping and deformation. The temporary support device mainly comprises two magnetic connecting base plates 1, two connectors 3, and a set of strut assemblies 4.

[0021] The magnetic connection substrate 1 is a magnetic suction plate made of magnetically conductive steel, which is pre-installed symmetrically and firmly on the two end sides of the prefabricated building module that require support through welding, bolting, or embedding. Each magnetic connection substrate 1 is divided into specific functional areas: a positioning area 17 near both ends, a magnetic adsorption area 18 between the two positioning areas, and a weakly magnetic or non-magnetic area 19 adjacent to the magnetic adsorption area 18. The magnetic adsorption area 18 can be made to have high magnetic permeability through heat treatment, material selection, or structural design, while the weakly magnetic or non-magnetic area 19 can be achieved through methods such as embedding magnetic shielding materials or local annealing. In the positioning area 17, one or more positioning holes 20 are formed on the magnetic connection substrate 1.

[0022] Each connector 3 is typically made of a robust material such as steel plate. A magnetic connector 2 is fixedly mounted on the side facing the magnetic connection substrate 1; in this embodiment, a high-performance permanent magnet (such as neodymium iron boron) is preferably used. A guide sleeve is fixed or integrally formed on the connector 3, and at least one (preferably two symmetrically arranged) guide rod 12 slides through the guide sleeve. A first positioning seat 13a and a second positioning seat 13b are fixedly connected to both ends of the guide rod 12, respectively. An elastic element 14, in this embodiment a compression spring, is sleeved on the guide rod 12 between the first positioning seat 13a and the connector 3. This element always applies a force towards the second positioning seat 13b or maintains a pre-tightened state. A pushing mechanism 21, in this embodiment a manual screw jack or a hydraulic jack, is mounted on the second positioning seat 13b via a bracket. A pad 15 is fixed to the end of the telescopic rod of the pushing mechanism 21, and the pad 15 also slides on the guide rod 12, with its working surface facing the connector 3. A positioning element 16 is fixed to the end face of the first positioning seat 13a and / or the second positioning seat 13b facing the magnetic connection substrate 1. In this embodiment, it is a positioning rod. The positioning rod cooperates with the positioning hole 20.

[0023] The strut assembly 4 connects between two connectors 3 to provide core support. It mainly consists of a first strut 5 (such as a square or round steel tube) as the main body and a second strut 6 that is telescopically inserted into it. The second strut 6 has a series of equally spaced adjustment holes 8 along its length. By aligning different adjustment holes 8 with corresponding holes on the first strut 5 and inserting a first locking element 7 (such as a bolt and nut), the relative positions of the first strut 5 and the second strut 6 can be fixed, thereby adjusting the overall length of the strut assembly 4. The end of the second strut 6 is detachably connected to one connector 3 via a second locking element 9. The end of the first strut 5 is connected to another connector 3 via a connecting sleeve 10. Specifically, one end of the connecting sleeve 10 is fitted over the end of the first strut 5 and fixed by a third locking element 22; the other end of the connecting sleeve 10 is inserted into the corresponding connector 3 and fixed by a fourth locking element 11. This segmented, bolted structure allows the entire device to be disassembled into smaller parts, facilitating packaging, transportation, and storage. In this embodiment, the first locking member 7, the second locking member 9, the third locking member 22, and the fourth locking member 11 can all be structures with bolts and nuts.

[0024] The installation process of the temporary support device of this utility model is as follows: Based on the dimensions of the prefabricated building module to be hoisted, the length of the support rod assembly 4 is pre-adjusted and locked with the first locking member 7. The assembled temporary support device is moved next to the module, aligning the magnetic connectors 2 on the two connectors 3 with the magnetic adsorption areas 18 of the magnetic connection base plates 1 fixed on both sides of the module. At the same time, ensure that the positioning member 16 is aligned with the positioning hole 20 on the magnetic connection base plate 1. Push the entire device, and the magnetic connectors 2 are quickly attracted to the magnetic adsorption areas 18 under the action of magnetic force, while the positioning member 16 is inserted into the positioning hole 20, completing precise positioning. At this time, the device is firmly fixed to the module, and the elastic element 14 may be in a slightly compressed state.

[0025] The disassembly process of the temporary support device of this utility model is as follows: After hoisting into place, the temporary support device needs to be removed. Operate the two jacking mechanisms 21 sequentially, extending their telescopic rods to push the corresponding connector 3 through the pad 15. The connector 3 overcomes the force of the elastic element 14 and slides along the guide rod 12 towards the first positioning seat 13a. After sliding a certain distance, the magnetic connector 2 moves from the magnetic adsorption area 18 to the weakly magnetic or non-magnetic area 19. Since the attraction of the weakly magnetic or non-magnetic area 19 to the magnetic connector 2 is very small or zero, the entire support device can be easily removed from the prefabricated building module. Release the jacking mechanism 21, and the connector 3 returns to its original position under the action of the elastic element 14.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
