Description

Technical Field

[0001] This utility model relates to the field of light steel construction technology, and in particular to a temporary turnover device suitable for light steel keel. Background Technology

[0002] Light steel keel construction is a building system that uses cold-formed thin-walled steel as the main load-bearing and enclosure structure. It has the advantages of light weight, high strength, and fast construction speed, and is widely used in residential, public buildings and renovation projects.

[0003] However, in the current construction process, such as Figure 1 As shown, modularly assembled light steel keel components often lack dedicated temporary storage facilities and are frequently piled haphazardly on the construction site ground. This disorderly stacking not only occupies valuable working space and affects material handling efficiency, but also easily leads to component deformation, impact damage, and safety hazards for on-site passage, hindering construction progress and quality control. Furthermore, if the construction site experiences rainfall, the stacked light steel keels are easily exposed to mud and water for extended periods, causing component contamination and potentially affecting the long-term durability and structural safety of the materials, while also exacerbating site chaos and handling difficulties. Therefore, there is an urgent need for a temporary storage facility that can orderly stack components, protect them, and improve construction efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a temporary turnover device suitable for light steel keel, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A temporary turnover device for light steel keel includes a turnover support frame for supporting a light steel keel frame that is placed horizontally on its side. The turnover support frame includes a pair of vertically arranged right-angled triangular frames and several horizontal connecting rods connecting the two right-angled triangular frames; The hypotenuses of the pair of right-angled triangular frames together form an oblique support surface to support the light steel keel frame. The oblique support structure creates a height difference, making it easy to retrieve the light steel keel frame from the turnover support frame; the vertical right-angled sides of the pair of right-angled triangular frames together form a rear support surface. The top of the rear support surface extends upward and is provided with a limiting bracket, which is used to abut against the uppermost light steel keel frame during operation. The inclined support surface is provided with a plurality of limiting rods arranged in a linear array along the inclined direction; the limiting rods are arranged parallel to the connecting rods; The limiting rod has a right-angled triangle cross-section, with one right-angled side fitting and fixed to the hypotenuse of the right-angled triangle frame. The angle between the hypotenuse and the horizontal direction is 10°-15°, and the outer side of the hypotenuse is higher than the inner side, which facilitates the stable support of the light steel keel frame.

[0006] Preferably, the right-angled triangular frame has two parallel diagonal reinforcing beams inside, and a vertical reinforcing beam vertically arranged between the two diagonal reinforcing beams, which improves the structural strength of the right-angled triangular frame and enhances the stability and reliability of the support.

[0007] Preferably, the rear support surface is provided with a pair of V-shaped reinforcing beams arranged in an inverted V shape to improve the structural strength of the rear support surface and enhance the stability and reliability of the support.

[0008] Preferably, the inclined support surface is provided with several auxiliary support beams parallel to the hypotenuse of the right-angled triangular frame to enhance the bearing capacity of the inclined support surface.

[0009] Preferably, the outer side of the right-angled triangular frame is provided with hooks near the two acute angles for hanging rain curtains. In rainy weather, the rain curtain can be quickly covered on the light steel keel frame through the hooks.

[0010] Preferably, the inclined surface of the limiting rod is covered with an anti-slip wave layer to improve the supporting stability of the limiting rod on the bottom of the light steel keel frame.

[0011] Compared with the prior art, the temporary turnover device for light steel keel of this application has the following advantages: 1. Achieve orderly stacking, improve space utilization and work efficiency: By placing the light steel keel frame horizontally on the turnover support frame, the disorderly stacking of the direct ground is overcome. The slanted support surface and the rear support surface together form a stable support structure, which allows multi-layer keel frames to be stacked neatly and compactly, significantly reducing the floor space occupied, freeing up working space, facilitating material management and transportation, and thus improving construction efficiency.

[0012] 2. Effective protection of components, preventing deformation and damage: The limiting frame can abut against the uppermost keel frame to prevent it from sliding backward; while the right-angled triangular limiting rod set at a specific angle (10°-15°) on the inclined support surface, with its outer hypotenuse higher than its inner side, forms a stable fit with the bottom surface of the light steel keel. Combined with the design of the anti-slip wave layer, they together play an effective anti-slip and limiting role, avoiding the sliding and bumping of components during stacking and handling, reducing the risk of deformation and surface damage, and ensuring the quality of the components.

[0013] 3. Enhanced stability and safety: The turnover support frame itself is reinforced with multiple structures, including diagonal reinforcing beams, vertical reinforcing beams, V-shaped reinforcing beams, and auxiliary support beams, ensuring the rigidity and load-bearing capacity of the overall device. It can stably support a large number of keel frames, reducing the safety hazard of tipping over due to unstable support and improving the safety of the construction site.

[0014] 4. Rainproof function and improved environmental adaptability: The hooks set on the right-angled triangular frame make it easy to quickly hang rain curtains in rainy weather, effectively covering the stacked light steel keel frame. Combined with the supporting role of the turnover support frame itself, it avoids direct contact between the components and mud and water, prevents pollution and potential corrosion, ensures the durability of materials, and enhances the applicability of the equipment under different weather conditions.

[0015] 5. Easy to access and optimized operating experience: The height difference naturally formed by the inclined support structure makes it easier and more convenient for operators to access and place the light steel keel frame at different heights, further improving the convenience of turnover operations.

[0016] In summary, this utility model not only solves the space, efficiency, and safety problems caused by disorderly stacking, but also effectively protects the quality of components through structural design and enhances environmental adaptability. It has a significant positive effect on improving the overall efficiency and quality control of light steel keel building construction. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example

[0020] like Figures 2 to 8 As shown, a preferred embodiment of this utility model provides a temporary turnover device suitable for light steel keel.

[0021] The temporary turnover device mainly includes a turnover support frame 1 welded from metal square tubes (e.g., galvanized square steel tubes with a cross-section of 30mm×30mm). The turnover support frame 1 is used to support the light steel keel frame 100, which is placed horizontally on its side.

[0022] Specifically, the turnover support frame 1 includes a pair of vertically arranged and parallel right-angled triangular frames 2. Each right-angled triangular frame 2 is welded from square tubing and is shaped like a standard right-angled triangle, including a vertical right-angled side 21, a horizontal right-angled side 22, and a hypotenuse 23. Between the two right-angled triangular frames 2, several parallel connecting rods 3 are horizontally welded, which firmly connect the two triangular frames 2 into a stable three-dimensional frame structure.

[0023] The hypotenuses 23 of the pair of right-angled triangular frames 2 together form an inclined support surface for supporting the light steel keel frame 100. The vertical right-angled sides 21 of the pair of right-angled triangular frames 2 together form a vertical rear support surface.

[0024] A rectangular limiting frame 4 is welded upwards from the top of the rear support surface. This limiting frame 4 is used to abut against the uppermost light steel keel frame 100 during operation to prevent the entire stack from tilting backwards and tipping over.

[0025] On the inclined support surface, several limiting rods 5 arranged in a straight array are welded along the inclined direction. These limiting rods 5 are arranged parallel to the connecting rod 3. The cross-section of the limiting rod 5 is a right-angled triangle, formed by extrusion molding. One right-angled side 51 is fixed to the upper surface of the hypotenuse 23 of the right-angled triangle frame 2 by welding (or threaded connection). The angle α between the hypotenuse 52 and the horizontal direction is 10° (preferably within the range of 10°-15°), and the outer side (the side away from the rear support surface) of the hypotenuse 52 is higher than the inner side. This design causes the bottom surface of the light steel keel frame 100 placed on the hypotenuse 52 to generate an inward component force under the action of gravity, thereby achieving a self-locking and anti-slip effect. To further enhance the friction, an anti-slip corrugated layer 6 (such as a corrugated rubber pad or a metal plate with concave and convex textures) is covered on the inclined surface 52 of the limiting rod 5 by bonding or welding.

[0026] To enhance the structural strength of the turnover support frame 1, in this embodiment: like Figure 6 As shown, the right-angled triangular frame 2 has two parallel diagonal reinforcing beams 24 welded inside, and a vertical reinforcing beam 25 vertically arranged between the two diagonal reinforcing beams 24.

[0027] The rear support surface is internally welded with a pair of V-shaped reinforcing beams 7 arranged in an inverted V shape.

[0028] The inclined support surface is internally welded with several auxiliary support beams 8 that are parallel to the hypotenuse 23 of the right-angled triangular frame 2.

[0029] In addition, such as Figure 7 As shown, hooks 9 for hanging rain curtains are welded to the outside of the right-angled triangular frame 2, near its right-angle vertex and acute-angle vertex, respectively. When it rains, construction workers can fix the corners of the waterproof canvas or plastic rain curtain to the hooks 9 to quickly form a canopy to protect the stacked light steel keel frame 100.

[0030] Working Principle: During use, place the device stably on a flat surface at the construction site. Workers then horizontally elevate each of the light steel keel frames 100, placing their bottom crossbeams on the inclined side 52 of the limiting rod 5 on the inclined support surface, and resting the upper part of the keel frame 100 against the turnover support frame 1. The top layer of the keel frame 100 is blocked by the limiting frame 4, and the frames are stacked layer by layer. When retrieving components, the natural height difference created by the inclined support surface allows operators to easily pick up and place the light steel keel frames 100. The entire stacking process is neat and stable, effectively utilizing vertical space and protecting the components.

[0031] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
