Description

Technical Field

[0001] This invention relates to the field of modular steel structure support technology, and in particular to a temporary support device for modular steel structures with locking function and its usage method. Background Technology

[0002] Modular steel structures refer to independent structural units prefabricated in factories using steel as the primary material. These units typically include integrated components such as frames, floor slabs, walls, and pipeline equipment. After being transported to the site, they are assembled with other modules through standardized connection nodes to quickly form a complete building structure. This industrialized construction method combines advantages such as high strength, lightweight, high construction efficiency, flexible space utilization, and low carbon footprint, making it a core technological carrier for modern prefabricated buildings and rapid emergency deployment.

[0003] In existing technologies, after steel structures are transported to the assembly location, the uninstalled steel structures need to be temporarily stacked. However, the conventional support frames currently used for temporary storage of modular steel structures have a limited function, providing only basic support and failing to reliably limit and fix the modular steel structure components placed on them. Operators also need to use additional fastening tools (such as straps, clamps, or bolts) to fix the components a second time, which not only increases the complexity and labor intensity of the construction process but also reduces on-site work efficiency, making it difficult to meet the construction requirements for rapid assembly of modular steel structures. Summary of the Invention

[0004] The purpose of this invention is to provide a modular steel structure temporary support device with locking function and its usage method, so as to solve the technical problems existing in the background art.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A modular steel structure temporary support device with locking function includes: a frame and support plates. The frame is U-shaped with its opening facing forward. Several support plates are evenly arranged vertically on the inner side of the frame. The modular steel structure is stored on the top of the corresponding support plate. The support plate is slidably installed on the inner side of the frame in the front-back direction. Several limiting mechanisms are evenly arranged on the left and right inner side walls of the frame. The limiting mechanisms are used to restrict the front-back sliding of the corresponding support plate. An adjustable limiting locking component is provided at the front center of the support plate to prevent the modular steel structure from sliding back and forth or tilting outward along the top of the support plate during storage.

[0006] Furthermore, two triangular support plates are symmetrically fixedly connected to the lower part of the left and right sides of the outer wall of the frame.

[0007] Furthermore, it also includes: sliders and slide rails. The support plate is rectangular. Two sliders are symmetrically fixedly connected to the side walls on the left and right sides of the support plate. The sliders have a T-shaped cross-section. Several slide rails are uniformly and symmetrically arranged along the height direction on the left and right inner side walls of the frame. Two T-shaped slide grooves are symmetrically opened on the two slide rails at the same height. The two sliders are slidably connected in the T-shaped slide grooves of the two slide rails corresponding to them.

[0008] Furthermore, it also includes: a limiting mechanism, wherein several limiting mechanisms are uniformly and symmetrically arranged along the height direction on the front part of the left and right inner sidewalls of the frame, and the several limiting mechanisms are arranged in pairs and corresponding to several support plates respectively; the limiting mechanism includes: a cam, a camshaft and two connecting plates, the cam is rotatably connected between the two connecting plates through the camshaft, and the connecting plates are fixedly connected to the inner sidewall of the frame; two limiting grooves are symmetrically opened on the front part of the left and right sides of the support plate, and the cams in the two limiting mechanisms at the same height are detachably engaged with the two limiting grooves on the corresponding support plates.

[0009] Furthermore, the connecting plate has a circular hole through which the camshaft passes and is fixedly connected to the cam. The two ends of the camshaft pass through and are rotatably connected to the circular holes on the two connecting plates respectively. A knob is coaxially fixedly connected to the front end of the camshaft.

[0010] Furthermore, the adjustable limiting and locking assembly includes: an adjusting plate, a threaded rod, guide sliders, and guide rails. A rectangular groove is formed in the center of the front end of the support plate. Two guide rails are symmetrically fixedly connected to the left and right sides of the rectangular groove. The adjusting plate is disposed within the rectangular groove, and two guide sliders are symmetrically fixedly connected to its left and right sidewalls. The two guide sliders are slidably mounted on the two guide rails in the front-back direction, respectively. The top surface of the adjusting plate is flush with the top surface of the corresponding support plate. The threaded rod extends longitudinally through and is threadedly connected to the adjusting plate. The rear end of the threaded rod is rotatably mounted in the center of the rear side of the inner wall of the rectangular groove. A rotating handle is fixedly connected to the front end of the threaded rod. A locking mechanism is provided on the adjusting plate to restrict the modular steel structure from sliding back and forth or tilting outwards along the top surface of the support plate during storage.

[0011] Furthermore, the locking mechanism includes: an adjusting handle, a locking rod, and a spring. Two locking rods and two springs are provided. Two vertically penetrating circular sliding holes are symmetrically opened on the left and right sides of the adjusting plate. The two locking rods are vertically slidably connected in the two circular sliding holes. The top left and right sides of the adjusting handle are fixedly connected to the bottom ends of the two locking rods respectively. The two springs are respectively sleeved on the two locking rods and their ends are fixedly connected to the adjusting handle and the adjusting plate respectively. Under no external force, the top of the locking rod extends above the adjusting plate.

[0012] Furthermore, the rear end of the locking rod extending from the adjusting plate is provided with an abutment groove, and a buffer pad is fixedly installed on the side of the abutment groove opposite to the inner wall of the rear side of the frame. The buffer pad is made of rubber.

[0013] A method for using a modular steel structure temporary support device with locking function, the method of use is as follows: When the modular steel structure needs to be temporarily stored, the operator pulls the support plate outward so that it slides smoothly out of the frame along the slide rail, exposing the support position on the support plate. Then, the modular steel structure is placed on the top surface of the support plate. Next, the support plate is pushed inward to reset, and then the cams on the left and right sides of the support plate are rotated by the knob so that the two cams are respectively engaged in the two limit grooves on the support plate. Then, the screw rod is rotated by rotating the handle, which in turn drives the adjusting plate to slide backward along the guide rail, so that the abutment grooves on the two locking rods in the locking mechanism are pressed into contact with the vertical side wall of the modular steel structure. When it is necessary to remove the stored modular steel structure, first turn the knob on the left and right sides of the support plate to completely disengage the two cams from the two limiting grooves on the support plate; then pull the support plate outward to make it slide smoothly out of the frame along the slide rail; then pull down the adjusting handle to make the exposed top parts of the two locking rods fully retract into the two circular sliding holes; at this time, the modular steel structure can be removed.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The adjustable limit locking component can quickly lock and fix the modular steel structure on the support plate without the need for external tools, effectively preventing the modular steel structure from sliding laterally along the support plate or tilting outward during storage. This significantly improves the safety and ease of operation during temporary storage. Rotating the threaded rod allows the adjusting plate to slide within the rectangular groove, thus adapting to the fixing of modular steel structures of different widths to a certain extent.

[0015] 2. The support plate slides and engages with the frame via a slide rail and is equipped with a limiting mechanism. This allows operators to easily pull out the support plate to access the upper modular steel structure, while also mechanically limiting the support plate after it is pushed in to prevent it from accidentally sliding out of the frame. This balances ease of operation with structural safety. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] See Figures 1-7 As shown, a modular steel structure temporary support device with locking function includes: a frame 1 and support plates 11. The frame 1 is U-shaped with its opening facing forward. Several support plates 11 are evenly arranged on the inner side of the frame 1 along the vertical direction, which can realize the layered storage of multiple sets of modular steel structure components and increase the storage capacity of modular steel structure components on the construction site. The modular steel structure is stored on the top of the corresponding support plate 11, and the support plate 11 is slidably installed on the inner side of the frame 1 along the front and back direction. Several limiting mechanisms 2 are evenly arranged on the left and right inner side walls of the frame 1. The limiting mechanisms 2 are used to restrict the front and back sliding of the corresponding support plate 11. An adjustable limiting locking component is provided at the front middle of the support plate 11 to prevent the modular steel structure from sliding back and forth or tilting outward along the top of the support plate 11 during storage.

[0020] In this embodiment, two triangular support plates are symmetrically fixedly connected to the lower part of the left and right sides of the outer wall of the frame 1. The triangular support plates utilize the principle of triangle stability to effectively enhance the structural rigidity of the overall frame 1 and improve the frame 1's resistance to tipping and deformation.

[0021] In this embodiment, the modular steel structure temporary support device with locking function further includes: sliders and slide rails 14. The support plate 11 is rectangular. Two sliders are symmetrically fixedly connected to the side walls on the left and right sides of the support plate 11. The sliders have a T-shaped cross section. Several slide rails 14 are uniformly and symmetrically arranged on the left and right inner side walls of the frame 1 along the height direction. Two T-shaped slide grooves are symmetrically opened on the two slide rails 14 at the same height. The two sliders are slidably connected in the T-shaped slide grooves of the two slide rails 14 corresponding to them. When the support plate 11 is pulled outward, its upper support space can be exposed, which makes it convenient for operators to pick up and put down the modular steel structure components located at high positions.

[0022] In this embodiment, the modular steel structure temporary support device with locking function further includes: a limiting mechanism 2. Several limiting mechanisms 2 are uniformly and symmetrically arranged along the height direction on the front part of the left and right inner sidewalls of the frame 1. The several limiting mechanisms 2 are arranged in pairs and correspond to several support plates 11 respectively. The limiting mechanism 2 includes: a cam 22, a cam shaft and two connecting plates 21. The cam 22 is rotatably connected between the two connecting plates 21 through the cam shaft. The connecting plates 21 are fixedly connected to the inner sidewall of the frame 1. Two limiting grooves 15 are symmetrically opened on the front part of the left and right sides of the support plate 11. The cam 22 in the two limiting mechanisms 2 at the same height is detachably engaged with the two limiting grooves 15 on the corresponding support plate 11. The cam 22 and the limiting groove 15 cooperate to form a mechanical limit, lock the sliding degree of freedom of the support plate 11, prevent the support plate 11 from sliding outward due to construction vibration or external force, and eliminate the risk of modular steel structure components falling.

[0023] In this embodiment, a circular hole is provided on the connecting plate 21, through which the camshaft passes and is fixedly connected to the cam 22. The two ends of the camshaft pass through and are rotatably connected to the circular holes on the two connecting plates 21 respectively. A knob is coaxially fixedly connected to the front end of the camshaft. The cam 22 can be rotated by rotating the knob, which is convenient for operation.

[0024] In this embodiment, the adjustable limiting locking assembly includes: an adjusting plate 12, a threaded rod 13, a guide slider, and a guide rail 16. A rectangular groove is provided in the middle of the front end of the support plate 11. Two guide rails 16 are symmetrically fixedly connected to the left and right sides of the rectangular groove. The adjusting plate 12 is set in the rectangular groove, and two guide sliders are symmetrically fixedly connected to the side walls on its left and right sides. The two guide sliders are slidably installed on the two guide rails 16 in the front-back direction, respectively. The top surface of the adjusting plate 12 is flush with the top surface of the corresponding support plate 11. The threaded rod 13 runs longitudinally through and is threadedly connected to the adjusting plate 12. The rear end of the threaded rod 13 is rotatably installed in the middle of the rear side of the inner wall of the rectangular groove. A rotating handle is fixedly connected to the front end of the threaded rod 13. A locking mechanism 3 is provided on the adjusting plate 12. The locking mechanism restricts the modular steel structure from sliding back and forth or tilting outward along the top surface of the support plate 11 during storage.

[0025] For modular steel structure components of different widths, the operator rotates the threaded rod 13 by turning the handle, which drives the adjusting plate 12 to slide horizontally and longitudinally along the guide rails 16 on both sides of the rectangular groove, adjusting the longitudinal position of the adjusting plate 12 so that the locking mechanism 3 on the outside of the adjusting plate 12 can adapt to the width of the side wall of the modular steel structure.

[0026] In this embodiment, the locking mechanism 3 includes: an adjusting handle 31, locking rods 32, and springs. Two locking rods 32 and two springs are provided. Two vertically penetrating circular sliding holes are symmetrically opened on the left and right sides of the adjusting plate 12. The two locking rods 32 are vertically slidably connected within the two circular sliding holes. The top left and right sides of the adjusting handle 31 are fixedly connected to the bottom ends of the two locking rods 32, respectively. Two springs are respectively sleeved on the two locking rods 32, and their ends are fixedly connected to the adjusting handle 31 and the adjusting plate 12, respectively. Without external force, the top of the locking rod 32 extends above the adjusting plate 12; the rear end of the portion of the locking rod 32 extending beyond the adjusting plate 12 opens... A notch 33 is provided, and a buffer pad made of rubber is fixedly installed on the side of the notch 33 opposite to the inner rear wall of the frame 1. When the modular steel structure is placed on the support plate 11, its front end cooperates with the notch 33, and the front side wall of the support plate 11 is in close contact with the buffer pad. The locking rod 32 forms a lateral limiting constraint on the modular steel structure component at the upper end of the support plate 11, restricting the steel structure from shifting outward. When it is necessary to remove the modular steel structure, the support plate 11 is pulled out, and the adjusting handle 31 is pulled down to lower the locking rod 32. The locking rod 32 no longer limits the modular steel structure, thus making it easy to pull the steel structure out of the support plate 11.

[0027] A method for using a modular steel structure temporary support device with locking function is as follows: When it is necessary to temporarily store the modular steel structure, the operator pulls the support plate 11 outward so that it slides smoothly out of the frame 1 along the slide rail 14, exposing the support position on the support plate 11, and then places the modular steel structure on the top surface of the support plate 11; then, push the support plate 11 inward to reset it, and then rotate the cams 22 on the left and right sides of the support plate 11 by turning the knob so that the two cams 22 respectively engage with the two limiting grooves 15 on the support plate 11; then, drive the threaded rod 13 to rotate by turning the handle, thereby driving the adjusting plate 12 to slide backward along the guide rail 16, so that the abutment grooves 33 on the two locking rods 32 in the locking mechanism 3 press against the vertical side wall of the modular steel structure; When it is necessary to remove the stored modular steel structure, first turn the knob on the left and right sides of the support plate 11 to make the two cams 22 completely disengage from the two limiting grooves 15 on the support plate 11; then pull the support plate 11 outward to make it slide smoothly out of the frame 1 along the slide rail 14; then pull down the adjusting handle 31 to make the exposed top parts of the two locking rods 32 completely retract into the two circular sliding holes; at this time, the modular steel structure can be removed.
