Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel bar stacking rack. Background Technology

[0002] As an important building material, steel bars are in high demand during construction. With the development of the construction industry, the requirements for safe and civilized construction and standardized production on construction sites are becoming increasingly stringent. The proper stacking and storage of steel bars is crucial. Generally speaking, a special area is designated on the construction site for storing steel bars.

[0003] In most cases, steel bars are stored directly on the ground at construction sites, resulting in extensive direct contact between the bars and the ground. During rainy weather, rainwater easily accumulates, causing the bars to be submerged for extended periods. This makes the bars highly susceptible to oxidation and rust, affecting their quality and performance. Furthermore, the lack of effective separation measures between bars of different specifications leads to mixing during handling and storage. This not only inconveniences material selection during construction but also risks the incorrect use of different specifications, impacting the quality and safety of the construction project.

[0004] Therefore, existing technologies employ cast-in-place concrete beams with embedded I-beams to hold reinforcing bars, using the I-beams to separate bars of different specifications. While this method addresses the issues of water damage and mixed specifications of the reinforcing bars to some extent, it has significant drawbacks. First, once the concrete beams and embedded I-beams are constructed, they are difficult to reuse. If construction is completed or the rebar storage area needs to be changed, these fixed structures cannot be relocated, resulting in resource waste. Second, dismantling the concrete beams requires substantial manpower, resources, and time, increasing construction costs, and may also generate construction waste, causing environmental impact. Utility Model Content

[0005] The purpose of this utility model is to provide a steel bar stacking rack to solve the technical problems of high cost and poor flexibility in the existing technology of using cast-in-place concrete beams and pre-embedded I-beams to store steel bars.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0007] A steel bar stacking rack, comprising:

[0008] At least two support columns, each of which has a support base at its bottom;

[0009] A support crossbar is provided between two adjacent support vertical bars. The support crossbar and the support vertical bar are detachably connected by a fastener. The support crossbar is provided in at least one layer along the height direction of the support vertical bar. A mounting surface is formed on the support crossbar. The mounting surfaces of the support crossbars located in the same layer are located in the same horizontal plane, and the reinforcing bars can be stacked on the mounting surface.

[0010] Preferably, the steel bar stacking rack includes multiple interconnected support units, each support unit being rectangular, and each support unit including four support vertical rods, the four support vertical rods being located at the four corners of the rectangle.

[0011] Preferably, in two adjacent support units, the two adjacent sides share the same support vertical rod and the support horizontal rod.

[0012] Preferably, the supporting vertical rod has four connecting surfaces, with two adjacent connecting surfaces perpendicular to each other and two opposite connecting surfaces parallel to each other, and each connecting surface can connect to the supporting horizontal rod.

[0013] Preferably, the supporting vertical rod includes a first horizontal plate and two first vertical plates, which are arranged in an I-shape. The two sides of the first horizontal plate serve as the connecting surfaces, and the side of the first vertical plate away from the horizontal plate serves as the connecting surface.

[0014] Preferably, the fastener includes a first plate and a second plate that are perpendicular to each other and fixedly connected, the first plate being bolted to the supporting vertical rod and the second plate being bolted to the supporting horizontal rod.

[0015] Preferably, two fixing members are provided for each of the supporting crossbars. The second plates of the two fixing members are spaced apart along the width direction of the supporting crossbar. The supporting crossbar can be clamped between the two second plates. Through holes are opened on the second plates and the supporting crossbar respectively. Locking bolts can pass through the through holes in sequence and be fixed by locking nuts.

[0016] Preferably, the height of the supporting vertical rod is adjustable.

[0017] Preferably, the bottom of the support vertical rod is welded to the support base.

[0018] Preferably, the mounting surface is provided with a wear-resistant coating.

[0019] The beneficial effects of this utility model are:

[0020] The rebar stacking rack proposed in this utility model, through a structure composed of supporting vertical and horizontal bars, allows rebars to be placed on the mounting surface of the supporting horizontal bars, avoiding direct contact with the ground. This effectively prevents rusting caused by rainwater immersion, ensuring the quality and performance of the rebars. The support base improves the stability of the supporting vertical bars, preventing the rebar stacking rack from tipping over or deforming during use. Since the supporting horizontal bars are arranged in at least one layer along the height of the supporting vertical bars, rebars of different specifications can be placed in layers and classified, or separated by the supporting vertical bars, resulting in neat and orderly stacking. The mounting surfaces of the same layer are on the same horizontal plane, providing a stable placement position for the rebars and ensuring clear differentiation between different specifications, preventing mixing. Furthermore, the design of detachable connection between the supporting horizontal and vertical bars through fasteners improves the flexibility and reusability of the rebar stacking rack. When construction is completed or the stacking site needs to be changed, it can be easily disassembled, moved, and reassembled. Attached Figure Description

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] See Figures 1 to 6 The steel bar stacking rack provided in this embodiment of the utility model includes supporting vertical rods 1 and supporting horizontal rods 3. There are at least two supporting vertical rods 1, and each supporting vertical rod 1 has a supporting base 2 at its bottom. A supporting horizontal rod 3 is provided between two adjacent supporting vertical rods 1, and the supporting horizontal rod 3 and the supporting vertical rod 1 are detachably connected by a fastener 4. At least one layer of supporting horizontal rods 3 is provided along the height direction of the supporting vertical rods 1. A mounting surface 30 is formed on the supporting horizontal rod 3, and the mounting surfaces 30 of the supporting horizontal rods 3 located in the same layer are located in the same horizontal plane, allowing steel bars 100 to be stacked on the mounting surface 30.

[0038] The rebar stacking rack proposed in this utility model, through a structure composed of supporting vertical rods 1 and supporting horizontal rods 3, allows rebars 100 to be placed on the mounting surface 30 of the supporting horizontal rods 3, avoiding direct contact with the ground and effectively preventing rusting caused by rainwater immersion, thus ensuring the quality and performance of the rebars 100. The supporting base 2 improves the stability of the supporting vertical rods 1, preventing the rebar stacking rack from tipping over or deforming during use. Since the supporting horizontal rods 3 are arranged in at least one layer along the height direction of the supporting vertical rods 1, rebars 100 of different specifications can be placed in layers and classified, or separated by the supporting vertical rods 1, resulting in neat and orderly stacking of the rebars 100. The mounting surfaces 30 of the same layer are on the same horizontal plane, providing a stable placement position for the rebars 100 and ensuring clear distinction between rebars 100 of different specifications, preventing them from mixing. Furthermore, the design of the detachable connection between the supporting horizontal rods 3 and the supporting vertical rods 1 via fasteners 4 improves the flexibility and reusability of the rebar stacking rack. When construction is completed or the storage site needs to be changed, it can be easily disassembled, moved and reassembled.

[0039] In this embodiment, the supporting vertical rod 1 extends vertically perpendicular to the ground, and the supporting horizontal rod 3 extends horizontally parallel to the ground. For the convenience of describing in conjunction with the accompanying drawings, the directions described below are based on the directions shown in the accompanying drawings, but are not limited thereto.

[0040] The specific structure of the rebar stacking rack is described below.

[0041] The rebar stacking rack comprises multiple interconnected support units, each rectangular in shape. Each support unit includes four supporting vertical rods 1, located at the four corners of the rectangle. These four corner rods 1 evenly distribute the weight of the rebar 100 above, resulting in a more balanced force distribution when the entire support unit is under load, thus improving the overall structural stability and load-bearing capacity. The rectangular shape better adapts to site planning and layout, allowing multiple support units to be closely arranged, making full use of limited space and achieving efficient storage of the rebar 100.

[0042] In this embodiment, multiple support units are interconnected to form a rectangular rebar stacking rack. The specific number of support units is not limited; it can be selected adaptively based on actual conditions. In other embodiments, multiple support units can also be connected to form a circular, triangular, or irregularly shaped rebar stacking rack.

[0043] Specifically, in two adjacent support units, the two adjacent sides share the same vertical support rod 1 and horizontal support rod 3. The shared vertical support rod 1 and horizontal support rod 3 rely on each other and share the force, enhancing the connection stability between adjacent support units, better maintaining overall stability, and reducing swaying or deformation that may occur due to loose connections between units. In addition, the shared design makes the transition between adjacent support units more compact, reducing gaps and wasted space caused by independently installed components.

[0044] In other embodiments, each support unit may be provided with a separate support vertical rod 1 and support horizontal rod 3, and then the support vertical rod 1 and support horizontal rod 3 of adjacent support units may be connected, which will not be elaborated here.

[0045] The vertical support rod 1 is used to connect the horizontal support rods 3 to form a support unit. Specifically, the vertical support rod 1 has four connecting surfaces 10, each of which can connect to the horizontal support rod 3. Regardless of which connecting surface 10 the horizontal support rod 3 is installed on, it can form an effective support system with the vertical support rod 1, jointly bearing the weight of the steel bar 100 and the influence of the external environment, thus improving the stability and reliability of the entire steel bar stacking rack. Multiple connecting surfaces 10 make the arrangement of the horizontal support rods 3 more flexible and diverse. The connecting surfaces 10 of the horizontal support rods 3 can be reasonably selected according to the size and shape of the site and the stacking method of the steel bar 100, so as to achieve efficient use of space. Two adjacent connecting surfaces 10 are perpendicular to each other, and two opposite connecting surfaces 10 are parallel to each other, so as to construct a rectangular support unit through the connection of the horizontal support rods 3.

[0046] Specifically, the supporting vertical bar 1 includes a first horizontal plate 11 and two first vertical plates 12, arranged in an I-shape. Both sides of the first horizontal plate 11 serve as connecting surfaces 10, providing a stable connection base for the supporting horizontal bars 3. When connecting the supporting horizontal bars 3, they can be tightly fixed to the connecting surfaces 10 of the first horizontal plate 11 using bolts or welding. The side of the first vertical plate 12 away from the first horizontal plate 11 also serves as a connecting surface 10; its longer length allows for the connection of more supporting horizontal bars 3. In actual stacking operations, if it is necessary to increase the number of stacking layers or change the stacking layout, supporting horizontal bars 3 can be flexibly installed on this connecting surface 10 of the supporting first vertical plate 12. For example, when stacking a large number of thick steel bars 100, an additional layer of supporting horizontal bars 3 can be added to the connecting surface 10 of the first vertical plate 12 to enhance the load-bearing capacity of the entire stacking rack. Alternatively, when space is limited and the stacking direction of the reinforcing bars 100 needs to be changed, the position of the supporting crossbar 3 can be easily adjusted using the connecting surface 10 of the first longitudinal plate 12. The I-shaped supporting vertical bar 1 design not only achieves economic rationality in material usage, but also has high flexibility and stability in actual construction applications.

[0047] Specifically, the bottom of the support vertical rod 1 is welded to the support base 2, ensuring the integrity and stability of the connection. This allows the support vertical rod 1 to effectively transfer the weight it bears to the support base 2, distributing the pressure. The welding connection method is simple and direct, requiring no additional complex connectors, thus reducing the number of parts and the complexity of installation. At the same time, the welded structure has good sealing properties, preventing moisture, dust, and other impurities from entering the connection point, thereby extending the service life of the rebar stacking rack.

[0048] To improve the flexibility and adaptability of the support rod 1, in this embodiment, the height of the support rod 1 is adjustable. Specifically, each support rod 1 consists of two nested tubular components, with the inner diameter of the outer tube slightly larger than the outer diameter of the inner tube, allowing the inner tube to slide smoothly within the outer tube. Multiple positioning holes are evenly distributed along the length of the outer tube, while a resiliently extendable positioning pin is provided on the inner tube.

[0049] When it is necessary to adjust the height of the support rod 1, press down the positioning pin and slide the inner tube up and down inside the outer tube until the positioning pin on the inner tube is aligned with the positioning hole at the appropriate position on the outer tube. The positioning pin pops out under the action of elasticity and inserts into the positioning hole, thereby fixing the relative position of the inner tube and the outer tube and realizing the adjustment of the height of the support rod 1.

[0050] For example, when a large quantity of steel bars 100 needs to be stacked at a construction site, the height of the supporting vertical rod 1 can be increased to raise the stacking space, facilitating storage and retrieval. Conversely, when space is limited or a smaller quantity of steel bars 100 needs to be stacked, the height of the supporting vertical rod 1 can be lowered to save space. This height-adjustable design allows the steel bar stacking rack to better adapt to different construction needs and site conditions, improving its versatility and practicality.

[0051] The vertical support rod 1 and the horizontal support rod 3 are connected by a fastener 4. The fastener 4 includes a first plate 41 and a second plate 42 that are perpendicular to each other and fixedly connected. The first plate 41 is bolted to the vertical support rod 1, and the second plate 42 is bolted to the horizontal support rod 3.

[0052] Specifically, two fixing members 4 are provided for each supporting crossbar 3. The second plates 42 of the two fixing members 4 are spaced apart along the width direction of the supporting crossbar 3, and the supporting crossbar 3 can be clamped between the two second plates 42, thereby increasing the contact area and stability between the supporting crossbar 3 and the fixing members 4. Through holes are correspondingly opened on the second plates 42 and the supporting crossbar 3, and locking bolts can pass through the through holes in sequence and be fixed by locking nuts. During installation, the supporting crossbar 3 is first placed between the two second plates 42, aligning the through holes. Then, the locking bolts are passed through the aligned through holes, and the locking nuts are tightened on the other end of the bolts. The tightened locking nuts generate pressure, causing the second plates 42 to fit tightly against the supporting crossbar 3, thereby preventing the supporting crossbar 3 from moving or loosening during use. This design not only ensures the firmness of the connection between the supporting crossbar 3 and the fixing members 4, but also facilitates disassembly and adjustment when needed. For example, if the supporting crossbar 3 needs to be replaced or its position adjusted, simply loosen the locking nuts and remove the bolts to perform the corresponding operations.

[0053] The supporting crossbar 3 includes a second horizontal plate 31 and two second vertical plates 32, which are arranged in an I-shape. The second horizontal plate 31 can be clamped between the two second plates 42. The second plates 42 and the second horizontal plate 31 have corresponding through holes. Locking bolts can pass through the through holes in sequence and be fixed by locking nuts. Among the two second vertical plates 32, the top surface of the upper vertical plate forms a mounting surface 30 for mounting the reinforcing bar 100.

[0054] In this embodiment, the supporting horizontal bar 3 is provided in one layer, located on the bottom side of the supporting vertical bar 1. In other embodiments, two or three layers of supporting horizontal bars 3 may also be provided, and this is not limited here.

[0055] Specifically, a wear-resistant coating is applied to the mounting surface 30. This coating can be made of materials such as polymers, ceramics, or metal alloys. The presence of this coating effectively reduces friction and wear between the reinforcing bar 100 and the mounting surface 30. Even during frequent placement and movement of the reinforcing bar 100, the mounting surface 30 maintains good surface flatness and integrity, preventing dents, scratches, or damage due to wear. This extends the service life of the reinforcing bar stacking rack and reduces maintenance costs. Simultaneously, the wear-resistant coating also reduces resistance during the stacking and movement of the reinforcing bar 100, making operations smoother and more efficient.

[0056] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
