Description

Technical Field

[0001] The utility model relates to the field of building formwork, in particular to a steel structure formwork platform. Background Art

[0002] In many construction projects, large-span, ultra-high overhead concrete structures are often encountered. For example, in the local process production areas of large factories and the atriums of large shopping malls, these large-span, ultra-high overhead areas may be designed to meet production process requirements or to ensure lighting, ventilation, and personnel flow. The roof concrete structures in these areas have the characteristics of large spans, ultra-high structures, and large beam cross-sections, which bring many difficulties and challenges to the construction of roof structures. Currently, the bottom support systems of large-span, ultra-high overhead structures are mainly divided into two categories: full-span steel pipe support systems and Bailey frame support platforms. However, in the construction of roofs with spans less than 10m, traditional formwork structures use a large amount of steel, resulting in high costs and poor economic benefits. In addition, when there is a height difference in the roof structure, the existing formwork structures perform poorly in handling such complex situations, which affects the practicality and functionality of the formwork platform. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a steel structure formwork platform to solve the technical problem that when there is a height difference in the roof structure, the existing formwork structure has poor supporting effect and poor economic benefits.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel structure formwork platform, comprising a three-layer structural plate, a plurality of steel structure beams are arranged above the three-layer structural plate, a support frame is provided on the top of the steel structure beam, a formwork frame is provided on the top of the support frame, a roof concrete beam and slab is laid on the top of the formwork frame, a support mechanism is provided between one end of the steel structure beam and the three-layer structural plate, and the support mechanism includes supporting steel.

[0005] By adopting the above technical solution, the utility model has made clever design adjustments to address the situation where the two ends of the floor slab on which the I-beams are placed are of unequal height. First, by adding supporting steel at the low span to provide a solid supporting force, the stability of the overall structure is ensured. This measure effectively solves the structural problems that may be caused by the height difference at both ends of the floor slab.

[0006] Furthermore, mounting plates are provided on both the upper and lower sides of the support steel, and 4M20 pin holes are opened on the surface of the mounting plates, which are bolt connection points between the support steel and the steel structure beams and the three-layer structural plates.

[0007] By adopting the above technical solution, the mounting plate provides a stable interface for the connection between the supporting steel and the steel structure beams and the three-layer structural plate, ensuring the strength and stability of the connection points.

[0008] Furthermore, the plurality of steel structure beams are arranged linearly and equidistantly along the long line of the three-layer structural plate.

[0009] By adopting the above technical solution, the equidistant linear arrangement ensures load balance between the steel structure beams, prevents local stress concentration caused by uneven distribution of beams, and thus improves the stability and safety of the overall structure.

[0010] Furthermore, the model of the steel structure cross beam is HN350×175×7×11 steel beam, and the spacing between adjacent steel structure cross beams is 2.4m.

[0011] By adopting the above technical solution, the HN350×175×7×11 steel beam has a high load-bearing capacity and stability, which can ensure the overall stability of the formwork platform and provide safety for construction.

[0012] Furthermore, the support frame is composed of a plurality of HW100×100×6×8 longitudinal steel beams, and the spacing between adjacent longitudinal steel beams is 1.05m. The support frame is welded and fixed to the steel structure cross beams.

[0013] By adopting the above technical solution, the HW100×100×6×8 longitudinal steel beams have high strength and stability, which can effectively support the superstructure and ensure construction safety; the 1.05m spacing setting not only ensures the stability of the structure, but also optimizes material usage and avoids waste.

[0014] Furthermore, the support frame is welded with fixed steel pipes and steel bars and fully covered with 1mm thick floor decking for hard sealing to prevent debris from falling.

[0015] By adopting the above technical solution and welding the fixed steel pipes and steel bars, the stability and bearing capacity of the support frame are enhanced, providing a safer and more reliable working environment for construction.

[0016] Furthermore, the supporting steel has two but not limited to two length dimensions, which are used to adapt to the distance between the steel structure beam and the three-layer structural plate.

[0017] By adopting the above technical solution, support steels of different lengths can flexibly meet various spacing requirements, ensuring the stability and safety of the support structure. No matter how the spacing changes, suitable support steel can be found to match.

[0018] In summary, the present invention has the following beneficial effects:

[0019] The utility model uses steel structure beams, support frames and support mechanisms, steel structure truss beams and I-beam platforms with clear force, safety and reliability, and simple process. The steel sections of the steel structure truss beams and I-beam platforms have a high recycling rate and are economical and reasonable. The utility model can make full use of the bearing capacity of the steel structure platform structure itself placed on the cast-in-place structure floor, saving the investment in foundation reinforcement or floor top recovery, and well solving the problem that the beam and slab support top is prone to cause structural safety accidents, thereby improving its economic benefits. Furthermore, in view of the unequal heights of the two ends of the floor where the I-beams are placed, support steel is set at the low span plate as support, and a steel structure beam is added on the upper part. The support steel can be cut to different lengths according to actual conditions to adapt to the distance between the three-layer structure plate of the floor and the steel structure beam, which is conducive to making the formwork platform more environmentally applicable.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The following describes an embodiment of the present invention based on its overall structure.

[0029] A steel structure formwork platform, such as Figures 1-4 As shown, it includes three-layer structural plates 1, and multiple steel structure beams 2 are arranged above the three-layer structural plates 1. A support frame 3 is provided on the top of the steel structure beams 2, and a formwork frame 4 is provided on the top of the support frame 3. A roof concrete beam slab 5 is laid on the top of the formwork frame 4, and a support mechanism 6 is provided between one end of the steel structure beam 2 and the three-layer structural plate 1. The support mechanism 6 includes support steel 61. In view of the fact that the two ends of the floor slab where the I-beam is placed are not of equal height, the utility model has made clever design adjustments. First, by adding support steel 61 at the low span plate to provide a stable support force, the stability of the overall structure is ensured. This measure effectively solves the structural problems that may be caused by the height difference at both ends of the floor slab. At the same time, the steel structure beams 2 added on the upper part further strengthen the support system, making the entire formwork platform more solid. More importantly, the length of the support steel 61 can be flexibly cut according to the actual spacing requirements, which not only simplifies the installation process, but also greatly improves the adaptability of the formwork platform to different construction environments, thereby significantly improving its practicality and economic benefits.

[0030] See Figure 2 、 Figure 4 , mounting plates 62 are provided on the upper and lower sides of the supporting steel 61, and 4M20 pin holes are opened on the surface of the mounting plate 62, which are the bolt connection points between the supporting steel 61 and the steel structure beam 2 and the three-layer structure plate 1. The mounting plate 62 provides a stable interface for the connection between the supporting steel 61 and the steel structure beam 2 and the three-layer structure plate 1, ensuring the strength and stability of the connection point. At the same time, the 4M20 pin holes are used as bolt connection points, making the installation process more convenient and accurate, which not only improves the construction efficiency, but also enhances the reliability of the connection, optimizes the installation process, and improves the safety of the overall structure. It is a practical and efficient structural connection method.

[0031] See Figure 1 、 Figure 2, multiple steel structure beams 2 are arranged in an equidistant linear arrangement along the long line of the three-layer structural plate 1. The equidistant linear arrangement ensures the load balance between the steel structure beams 2, prevents local stress concentration caused by uneven distribution of beams, thereby improving the stability and safety of the overall structure. At the same time, this arrangement method also simplifies the positioning and installation work during the construction process, improves construction efficiency, and reduces the error rate. This arrangement method not only optimizes the structural force, but also facilitates construction operations.

[0032] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The model of the steel structure beam 2 is HN350×175×7×11 steel beam, and the spacing between adjacent steel structure beams 2 is 2.4m. The HN350×175×7×11 steel beam has a high bearing capacity and stability, which can ensure the overall stability of the formwork platform and provide safety for construction. At the same time, the 2.4m spacing is reasonably set, which not only ensures the stability of the structure, but also avoids material waste and achieves a balance between economy and safety. This choice of model and spacing enables the steel structure beam 2 to effectively support the superstructure and meet construction needs.

[0033] See Figure 1 、 Figure 2 The support frame 3 is composed of multiple HW100×100×6×8 longitudinal steel beams, and the spacing between adjacent longitudinal steel beams is 1.05m. The support frame 3 is welded and fixed to the steel structure crossbeam 2. The HW100×100×6×8 longitudinal steel beams have high strength and stability, which can effectively support the superstructure and ensure construction safety; the 1.05m spacing setting not only ensures the stability of the structure, but also optimizes the use of materials and avoids waste. At the same time, through welding fixation, the firm connection between the support frame 3 and the steel structure crossbeam 2 is ensured, further enhancing the stability and safety of the overall structure.

[0034] See Figure 1 、 Figure 2 、 Figure 3 The steel pipe reinforcement is welded and fixed on the support frame 3 and a 1mm thick floor decking is fully laid for hard sealing to prevent debris from falling. The welded and fixed steel pipe reinforcement enhances the stability and bearing capacity of the support frame 3, providing a safer and more reliable working environment for construction. At the same time, the 1mm thick floor decking is fully laid for hard sealing, which effectively prevents debris from falling, protects the safety of the construction site, and avoids the risk of injuries to workers or pedestrians below due to falling objects. It not only improves construction safety, but also reflects the importance attached to refined management of the construction site.

[0035] See Figure 2 、 Figure 4The support steel 61 is in two but not limited to two length sizes, which is used to adapt to the spacing between the steel structure beam 2 and the three-layer structural plate 1. Support steels 61 of different lengths can flexibly respond to various spacing requirements to ensure the stability and safety of the support structure. No matter how the spacing changes, suitable support steels 61 can be found to match. At the same time, this setting also improves the utilization rate of materials and reduces waste, because the length of the support steel 61 can be cut and selected according to actual needs instead of using fixed length materials. This flexibility and applicability makes the support structure more economical, efficient and safe.

[0036] The implementation principle of this utility model is:

[0037] Without main steel platform erection, horizontal HN350×175×7×11 steel structure beam 2 installation → HW100×100×6×8 longitudinal steel beam installation → steel platform floor slab laying → erecting formwork 4 → pouring roof concrete beam and slab 5 structure;

[0038] The demolition work must be carried out from top to bottom, first build and then dismantle, and dismantle layer by layer. It is strictly prohibited to work at the same time. The demolition order is: hard closed floor decking → HW100×100×6×8 longitudinal steel beam → transverse HN350×175×7×11 steel structure beam 2.

[0039] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.
