Description

Technical Field

[0001] This utility model relates to the field of eaves support structure technology, and in particular to an eaves support structure utilizing the silo wall. Background Technology

[0002] The eaves structure at the top of tall silos not only serves functions such as rain protection and aesthetics, but its construction process is also a key focus of risk control in the entire silo construction.

[0003] Currently, this type of construction typically uses a traditional ground-mounted steel pipe scaffolding support system, where full-span scaffolding is erected around the silo, extending from the ground all the way to the eaves working surface, providing an operating platform and support for formwork installation, concrete pouring and curing;

[0004] However, to meet the requirements for erecting tall silos, a huge amount of scaffolding materials are required, and the costs of renting, transporting, and erecting / dismantling are high. Furthermore, the erection and dismantling of scaffolding occupy a significant portion of the critical construction period, which cannot meet the tight schedule requirements of modern grain silo construction projects and has become a key factor restricting progress. Moreover, there are safety concerns. The overall stability control of ultra-high scaffolding is difficult, and the separation of the working platform from the protection system increases the risk of falls from heights and being struck by objects.

[0005] Based on this, an overhanging support structure utilizing the silo wall is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an overhanging support structure using the silo wall to solve the problems mentioned in the background art.

[0007] The technical solution of this utility model is: an eaves support structure utilizing the silo wall, comprising channel steel one and channel steel two, wherein channel steel one and channel steel two are pre-embedded in the silo wall, characterized in that it further comprises:

[0008] The steel pipe body is welded to the channel steel one and the channel steel two.

[0009] A steel pipe truss, wherein the steel pipe truss is welded from a steel pipe body, and the steel pipe truss is provided with bolts, and the steel pipe truss is fixedly connected to a pre-embedded channel steel one and a channel steel two by bolts;

[0010] Steel scaffolding boards are laid on top of the steel pipe truss.

[0011] In some embodiments, a protective structure is provided on the upper surface of the steel pipe truss, and a safety net is provided on the steel pipe truss through the protective structure.

[0012] In some embodiments, the protective structure includes vertical steel pipe uprights and horizontal steel pipe crossbars, which together form an outer enclosure frame, and the steel pipe uprights are fixedly connected to the upper surface of the steel pipe truss.

[0013] In some embodiments, the steel scaffold boards are evenly and linearly laid on top of the steel pipe truss to form a construction work platform.

[0014] In some embodiments, the safety net is attached to the outside of the protective structure to form a fully enclosed high-altitude operation protection system.

[0015] Compared with existing technologies, the significant advantages of this invention are:

[0016] Firstly, this utility model innovatively uses the silo wall structure itself as the load-bearing base point and adopts a connection method of welding pre-embedded parts and rigid support trusses to construct a cantilevered high-altitude work platform. This structure minimizes the reliance on external ground scaffolding and avoids the long cycle of traditional ground scaffolding being erected layer by layer from the ground, which helps to shorten the construction period.

[0017] Secondly, this utility model, by standardizing the installation of steel pipe uprights, crossbars, and dense safety netting around the perimeter of the working layer, creates a fully enclosed construction space simultaneously with the completion of the supporting structure, effectively eliminating the risks of falls from heights and being struck by objects. Compared to traditional construction platforms that require separate additional protective measures later, its safety and reliability are significantly enhanced. Using conventional steel and steel pipes, the structural force transmission path is clear, the nodes are reliable, and the safety reserve is high, ensuring safety and stability during construction.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved overhanging support structure utilizing the silo wall. The technical solution of this utility model is as follows:

[0025] like Figs. 1-2 As shown, a cantilever support structure utilizing the silo wall includes channel steel 3 and channel steel 5, which are embedded in the silo wall. It also includes:

[0026] The steel pipe body 1 is welded to the channel steel 1 3 and the channel steel 2 5;

[0027] The steel pipe fixed truss 2, through the combination of high-strength channel steel 1 3 and channel steel 2 5 with rigid steel pipe fixed truss 2, provides a stable and reliable load-bearing platform for eaves construction. The steel pipe fixed truss 2 is welded from the steel pipe body 1. The steel pipe fixed truss 2 is equipped with bolts 4. The steel pipe fixed truss 2 is fixedly connected to the pre-embedded channel steel 1 3 and channel steel 2 5 through the bolts 4.

[0028] Steel scaffolding boards are laid on top of the steel pipe truss 2. The fully laid steel scaffolding boards provide a wide and flat working surface, which can meet the needs of multiple construction processes to be carried out at the same time.

[0029] like Fig. 2 As shown, in one embodiment, a protective structure is provided on the upper surface of the steel pipe truss 2, and a safety net 9 is provided on the steel pipe truss 2 through the protective structure.

[0030] The protective structure includes vertical steel pipe uprights 7 and horizontal steel pipe crossbars 8, which together form the outer enclosure frame. The steel pipe uprights 7 are fixedly connected to the upper surface of the steel pipe truss 2.

[0031] like Fig. 2 As shown, in one embodiment, steel scaffold boards are evenly and linearly laid on top of the steel pipe truss 2 to form a construction work platform.

[0032] Safety net 9 is hung on the outside of the protective structure to form a fully enclosed high-altitude operation protection system. The integrated protective structure and safety net 9 system provide support and immediately create an inherently safe high-altitude operation environment. The safety net 9 is a flame-retardant dense mesh safety net 9, which constitutes a fully enclosed enclosure.

[0033] The specific working method is as follows: Before the slipform construction of the silo, accurately locate the positions of the pre-embedded channel steel 13 and channel steel 25 according to the detailed design drawings. Before the last lifting of the slipform template of the silo wall, reliably tie or weld the embedded parts of the channel steel to the main steel reinforcement skeleton of the silo to ensure that the elevation, verticality and exposed length of the embedded parts meet the design requirements. The pre-embedding is completed with the last concrete pouring. After the concrete strength reaches the design requirements, the subsequent work is carried out.

[0034] Using the operating platform suspended under the slipform system as the initial working surface, the pre-welded steel pipe truss 2 on the ground is hoisted to the working height. The steel pipe truss 2 is initially connected and fixed to the pre-embedded channel steel 3 and channel steel 5 by bolts 4. Then, full welding is carried out on site. The height and quality of the weld must meet the design specifications to ensure that the truss and the warehouse wall form a rigid connection.

[0035] After the steel pipe truss 2 is installed, welded, and inspected and approved, steel scaffold boards 6 are fully laid on its upper part. The scaffold boards must be firmly fixed between each other and between the scaffold boards and the truss to prevent movement or tilting, forming a safe and stable high-altitude work platform. Steel pipe uprights 7 are set up around the formed work platform, and two horizontal steel pipe crossbars 8 are set up to form a guardrail. Safety nets 9 are fully hung on the outside of the guardrail. The safety nets 9 must be firmly tied to form a fully enclosed protective space from bottom to top, effectively preventing personnel and materials from falling.

[0036] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
