Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an edge protection frame and a prefabricated outer edge beam. Background Technology

[0002] Heavy industry building upstairs refers to transforming inefficient single-story or multi-story factory buildings into high-standard, high-load, and high-quality high-rise factory buildings that meet the needs of industrial upgrading. This promotes the economical and intensive use of industrial land, expands the space for industrial development, and is a new type of industrial building model that can meet the problems of heavy equipment going upstairs, high load requirements for production space, and low freight efficiency in high-rise factory buildings.

[0003] In prefabricated buildings, precast beams are typically placed on pre-designed base columns. Both the base columns and the precast beams are square column structures with identical cross-sections. After the precast beams are hoisted onto the base columns using a crane, their edges require protection due to their considerable height. Traditionally, scaffolding is erected to prevent workers from accidentally falling during construction and ensure their safety. Edge beams are arranged along the edges of the building, primarily serving a supporting function and resisting lateral forces. Edge beams are divided into outer edge beams and inner edge beams. Outer edge beams bear the loads of the floor slab, the building envelope, wind forces, and externally suspended components. Inner edge beams bear the loads of the building's interior walls and floors.

[0004] Traditional scaffolding construction typically relies on a large amount of building materials such as steel pipes and couplers. Because different construction projects have varying requirements for the size and shape of scaffolding, materials often need to be cut and adjusted, resulting in material loss during each erection and dismantling process. Furthermore, both erecting and dismantling scaffolding require significant manpower and time, leading to high labor costs. When factory buildings have high ceilings, the height of the scaffolding also increases, posing a serious threat to the safety of construction workers working at heights.

[0005] This utility model proposes an edge protection frame and a prefabricated outer beam having the edge protection frame to solve the above problems. Utility Model Content

[0032] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," "left," "right," "front," and "rear" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0033] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0034] Example 1:

[0035] Reference Figure 1 The edge protection frame of this embodiment includes a support frame 1, a guardrail 2, a vertical bar 3, a diagonal bar 4, and a support rod 7.

[0036] Support rod 7 extends horizontally and can pass through the concrete beam along its thickness, providing stable foundation support for the edge protection frame, enhancing structural stability, and improving load-bearing capacity. The outer beam mainly consists of a concrete beam body and a steel reinforcement cage. The concrete beam body, the main body of the outer beam, bears the main loads and internal forces; it is elongated and has a rectangular cross-section. The steel reinforcement cage is a skeletal structure formed by connecting steel bars according to specific design requirements and structural forms, providing internal support and enhancing load-bearing capacity.

[0037] Support rod 7 extends beyond the rear end of the concrete beam with a length of at least 200 mm and beyond the front end with a length of at least 800 mm, to facilitate the fixing of other support or fixing structures at both ends of the concrete beam. One support rod 7 is inserted every 1000 mm along the length of the concrete beam, ensuring that it covers the entire edge of the concrete beam located on the outer side of the building. Figure 1 As shown in the front direction, the load on the supporting structure can be evenly distributed across multiple support rods 7 to avoid excessive local stress, which could lead to bending or deformation, thus ensuring the safety of construction workers. It should be noted that the spacing between two adjacent support rods 7 ranges from 800mm to 1200mm. Considering both accelerating construction time and reducing costs, while ensuring the structural stability of the support rods 7, a spacing of 1000mm is preferred in this embodiment.

[0038] The support frame 1 extends horizontally and is fixed to the front end of the support rod 7 to form a safe and stable working surface. The support frame 1 includes at least two horizontal bars 11 and at least two vertical bars 12. The horizontal bars 11 are all fixed parallel to the front end of the support rod 7 extending beyond the concrete beam, and the extension direction of the horizontal bars 11 is the same as that of the support rod 7. A vertical bar 12 is installed parallel to the horizontal bars 11 at 600mm intervals, and the vertical bars 12 are perpendicular to the horizontal bars 11. Together, they form a stable grid frame that can evenly distribute the load on the support frame 1, enhance the load-bearing capacity of the structure, and provide a stable operating platform for construction personnel.

[0039] In this embodiment, the left and right ends of the longitudinal member 12 are fixed to the leftmost and rightmost horizontal members 11 of the concrete beam respectively using bolts and fasteners. This ensures the horizontal stability and lateral displacement resistance of the longitudinal member 12, preventing horizontal displacement or torsion under stress, thus enhancing the stability of the entire support frame 1. The middle portion of the longitudinal member 12 only abuts against the horizontal member 11 located in the middle position, eliminating the need for bolts or fasteners. This reduces installation steps, lowers construction difficulty, increases construction speed, and reduces the use of fasteners and other fixing components, thereby reducing material and construction costs. Laying a steel platform or steel mesh on the support frame 1 ensures structural stability and the safety of construction personnel.

[0040] In this embodiment, a 600mm gap is left between the longitudinal bar 12 closest to the concrete beam and the concrete beam to provide sufficient space for the crane to lift the precast outer beam.

[0041] Furthermore, in order to strengthen the structural stability of the operating platform of the support frame 1 and ensure the safety of construction personnel during the construction process, vertical rods 3 and diagonal rods 4 are fixed on the support frame 1 to form a triangular support structure.

[0042] Specifically, the vertical rod 3 is fixed to the rear end of the horizontal rod 11 with bolts and fasteners, and the vertical rod 3 is located to the right of the horizontal rod 11 to which it is fixed. While ensuring a secure connection between the bolts and fasteners of the vertical rod 3 and the horizontal rod 11, the length of the vertical rod 3 extending upwards beyond the horizontal rod 11 is less than or equal to the distance between the support rod 7 and the concrete upper beam surface. This prevents the length of the vertical rod 3 extending upwards beyond the horizontal rod 11 from exceeding the concrete upper beam surface, thus avoiding obstruction of normal construction activities and ensuring the safety and smoothness of the construction process. The upper end of the diagonal rod 4 is fixed to the foremost vertical rod 12 with bolts and fasteners, and is located to the right of the horizontal rod 11 closest to it. The lower end of the diagonal rod 4 is fixed to the lower end of the vertical rod 3 with bolts and fasteners, and is located to the right of the vertical rod 3 to which it is fixed. It should be noted that the support frame 1, the vertical rod 3, and the diagonal rod 4 do not contact the precast outer beam concrete structure to avoid wear, collision, or other damage to the concrete beam surface, thus protecting the structural integrity and appearance of the concrete beam.

[0043] To facilitate the fixing of the diagonal brace 4 and ensure the stability of the bolt fastener fixing, the upper end of the diagonal brace 4 is higher than the vertical bar 12 by a certain length, and the lower end of the diagonal brace 4 extends to the rear side of the vertical bar 3 by a certain length.

[0044] To enhance the stability of the diagonal braces 4 in the lateral direction, i.e., along the length of the concrete beam, a connecting horizontal bar 6 is installed at the same height of all diagonal braces 4. The connecting horizontal bar 6 is fixed to each diagonal brace 4 using bolts and fasteners, thus connecting all diagonal braces 4 into a unified horizontal structure and enhancing structural stability. The left and right ends of the connecting horizontal bar 6 extend a certain length beyond the leftmost and rightmost diagonal braces 4, respectively, ensuring stable fixing of the diagonal braces 4 at both ends to the connecting horizontal bar 6 using bolts and fasteners.

[0045] After the precast outer beam is hoisted to the corresponding position, it is at a high height and poses a risk of working at height. In order to prevent construction workers from accidentally falling into the dangerous high-altitude area at the front end of the support frame 1, a guardrail 2 is vertically fixed at the end of the support frame 1 away from the support rod 7 to prevent construction workers from accidentally walking out of the edge of the support frame 1 and to ensure the safety of the construction workers.

[0046] The guardrail 2 includes at least two uprights 21 and at least one support rod 22. The uprights 21 are vertically fixed to the end of the horizontal bar 11 away from the support rod 7. The bottom end of the upright 21 is fixed to the frontmost vertical bar 12 and located at the front end of the vertical bar 12. The distance between two adjacent uprights 21 is 1000mm. To avoid crowding at the lower end of the uprights 21 and the upper end of the diagonal bar 4, making it inconvenient to fix the uprights 21, the uprights 21 are set on the left side of the horizontal bar 11 to ensure sufficient operating space when fixing the uprights 21 for easy installation.

[0047] In this embodiment, at least one support rod 22 is vertically fixed to the upper end of at least two uprights 21. At the same time, in order to enhance the stability of the guardrail 2 and prevent the uprights 21 from tilting or swaying, a support rod 22 can also be fixed at every 800mm interval to improve the wind and earthquake resistance of the guardrail 2, so as to cope with severe weather conditions and provide safer protection.

[0048] In this embodiment, according to safety regulations in the field of building construction, the height of the upright 21 extending out of the support frame 1 should not be less than 1.2m, which is well known to those skilled in the art.

[0049] The guardrail 2, consisting of at least two uprights 21 and at least one support 22, is only a protective mesh frame. There are large gaps in the front and back directions of the frame. In order to further protect the safety of construction workers, a dense safety net is laid on the guardrail 2 to fill the gaps. This effectively prevents the body parts of construction workers from passing through the gaps and prevents small tools and other objects that can pass through the gaps from falling, thus ensuring the safety of personnel and equipment below.

[0050] Furthermore, after the precast outer beams are hoisted to their designated positions, to ensure the safety of construction workers and prevent accidental falls from the edges of the support frame 1, diagonal braces 5 are installed at both ends of the support frame 1. The lower end of the diagonal brace 5 is fixed to the portion of the vertical rod 3 extending out of the support frame 1 using bolts and fasteners, and is located on the right side of the vertical rod 3. The upper end of the diagonal brace 5 is fixed to the support rod 22 and is located on the right side of the upright rod 21. Simultaneously, the diagonal brace 5, the guardrail 2, and the support frame 1 form a triangular support structure. In practical implementation, one diagonal brace 5 can be installed every 5-10 horizontal bars 11 to enhance the stability of the structure.

[0051] The angle between the diagonal brace 4 and the horizontal direction ranges from 45° to 60°, preferably 45°. The angle between the diagonal strut 5 and the horizontal direction also ranges from 45° to 60°, preferably 45°. In the triangular support structure, the isosceles right triangle support structure can evenly distribute the force on the hypotenuse onto the two legs, enhancing the structure's load-bearing capacity and stability.

[0052] All of the above-mentioned fixing methods use existing bolt-fastened fasteners that are detachable. Construction workers can choose different types of fasteners, such as right-angle fasteners, swivel fasteners, and butt fasteners, depending on the specific connection requirements.

[0053] Most common fasteners are used to fix steel pipes with an outer diameter of 48mm. Therefore, the above-mentioned horizontal bar 11, vertical bar 12, upright bar 21, support bar 22, vertical bar 3, diagonal bar 4, diagonal brace 5, connecting horizontal bar 6, and support bar 7 all use steel pipes with an outer diameter of 48mm.

[0054] Example 2:

[0055] This embodiment provides a precast outer beam, including a concrete beam body, connecting rod 8, and the edge protection frame of Embodiment 1.

[0056] Through holes, each 60mm in diameter, are provided at 1000mm intervals on the precast outer concrete beam. All through holes extend in the left-right direction and are at the same height. During the precast concrete beam construction, to create these through holes, sleeves are pre-embedded before concrete pouring, forming 60mm diameter through holes. Sleeves are installed within these through holes, and support rods 7 pass through the sleeves.

[0057] To enhance overall stability, the rear ends of multiple support rods 7 are connected into a whole to form a stable frame structure, which improves the stability of the edge protection frame, better resists loads, and prevents the edge protection frame from loosening due to the swaying of the support rods 7. A connecting rod 8 extending in the horizontal direction is provided and is vertically fixed to the rear ends of at least two support rods 7 by fasteners.

[0058] The construction process of one type of edge protection frame and prefabricated outer edge beam in this embodiment is as follows:

[0059] First, before pouring concrete for the precast outer beams in the prefabrication plant, a sleeve is pre-embedded every 1000mm along the length of the concrete beam's structural frame. Then, concrete is poured to create 60mm diameter through holes. After the concrete has solidified to the design strength, the precast outer beams are transported to the construction site. Subsequently, construction workers erect and fix a temporary edge protection frame on-site using 48mm steel pipes and bolt fasteners, and then conduct a load-bearing test on the frame. Finally, after the test confirms safety, the precast outer beams with the edge protection frame are hoisted to the appropriate position, effectively ensuring the safety of construction workers and improving the installation efficiency of the edge protection frame.
