Description

Technical Field

[0001] This application relates to the field of construction safety technology, and in particular to a protective device that facilitates the construction of a jump-bed method. Background Technology

[0002] The skip-construction method, a commonly used construction technique in building engineering, effectively reduces concrete shrinkage cracks by dividing the structure into several sections and constructing them in stages. It is widely used in numerous construction projects. With increasing emphasis on construction safety, the construction industry is imposing increasingly stringent safety requirements for high-altitude operations, making safety protection in construction increasingly crucial.

[0003] In related technologies, the construction industry commonly uses a variety of methods to solve the safety protection problems during the skip-scaffolding construction method. Among them, erecting full-span scaffolding is one of the more common methods. It can cover the entire construction area to ensure the safety of personnel and equipment during the construction process. Another method is to use independent suspended safety nets, which are highly flexible and can be adjusted according to the construction situation.

[0004] However, this method has the following drawbacks: the protection range of full-span scaffolding and independent suspended safety nets is limited, making it difficult to adapt well to the changes in height difference between high-level and low-level blocks, resulting in incomplete protection for construction workers and insufficient stability of protection, which leads to significant safety hazards at the construction site. Utility Model Content

[0005] To address the aforementioned issues, this application provides a protective device that facilitates the construction of the jump-pile method.

[0006] The protective device provided in this application, which facilitates the construction of the skip-pile method, adopts the following technical solution: A protective device for facilitating the skip-construction method is fixed to the construction blocks of the skip-construction method. It includes structural plates and a protective mechanism. The protective mechanism includes a first protective net, a second protective net, and a supporting frame. Two structural plates are provided, fixed to a high-level block and a low-level block of the skip-construction method, respectively. The supporting frame is located on the outside of the construction blocks of the skip-construction method. The two structural plates are vertically distributed and fixed to the structural plates. The supporting frame supports the first protective net to form a horizontal protective barrier and supports the second protective net to form a vertical protective barrier.

[0007] By adopting the above technical solution, the limited protection range of traditional full-span scaffolding is addressed. A first protective net forms a horizontal protective barrier, and a second protective net forms a vertical protective barrier, achieving complete coverage of the construction area. This increases the comprehensive protection for construction workers, simultaneously preventing falls and object drops. Furthermore, addressing the shortcomings of independently suspended safety nets in adapting to changes in height between high and low sections, the first and second protective nets can be adjusted to a fixed angle based on the height difference between the high and low sections. A supporting frame ensures that both nets remain taut at all times, effectively resisting deformation caused by concrete pouring impacts and changes in construction loads. The supporting frame is fixedly connected to the structural slab, enhancing the impact resistance of both nets and reducing safety hazards at the construction site.

[0008] Preferably, the support frame is configured as a plurality of spaced steel pipes, the support frame including a first support steel pipe, one end of the first support steel pipe being fixed to the upper structural plate, and the other end of the first support steel pipe being fixedly connected to the lower structural plate.

[0012] Preferably, the supporting frame further includes a first protective net support assembly, which includes several diagonal bracing steel pipes, several second supporting steel pipes, and several third supporting steel pipes. The diagonal bracing steel pipes are fixedly connected to the lower structural plate. The diagonal bracing steel pipes are inclined at a certain angle toward the outside of the construction block of the skip-section construction method. The middle part of the diagonal bracing steel pipe is fixedly connected to the first supporting steel pipe. Several second supporting steel pipes are perpendicular to the first supporting steel pipe and are distributed perpendicularly along the length of the second supporting steel pipe. The several second supporting steel pipes are parallel to each other. The side of several second supporting steel pipes near the construction block is fixedly connected to the first supporting steel pipe. The other side of several second supporting steel pipes is perpendicularly connected to several third supporting steel pipes. The top of the diagonal bracing steel pipe is fixedly connected to several second supporting steel pipes and several third supporting steel pipes.

[0013] By adopting the above technical solution, two structural plates are fixed to the high-level and low-level silos respectively. The support frame is distributed and fixed to the structural plates on the outside. The diagonal bracing steel pipes are connected to the lower structural plate and tilted at a certain angle. The middle part of the diagonal bracing steel pipe is fixed to the first support steel pipe, the top of the diagonal bracing steel pipe is fixed to the second support steel pipe, and the other side of the second support steel pipe is perpendicularly connected to the third support steel pipe. These features enable the formation of a stable transverse protective barrier support structure for the first protective net, ensuring the stable installation of the first protective net, improving the comprehensiveness and stability of the protection, and adapting to the height difference changes between silos in the skip-silo construction method.

[0014] Preferably, the first protective net is located between the structural plate and the third supporting steel pipe, with one side of the first protective net being fixedly connected to the structural plate and the other side of the first protective net being fixedly connected to the third supporting steel pipe.

[0015] By adopting the above technical solution, the first protective net is set between the structural plate and the third supporting steel pipe, and is fixedly connected to the structural plate and the third supporting steel pipe respectively. It can form a protective barrier in the lateral direction, which can play a role in protecting people from falling and improve the stability of the protection.

[0016] Preferably, the support frame further includes several fourth support steel pipes, and several third support steel pipes and several fourth support steel pipes vertically and fixedly support the second protective net.

[0017] By adopting the above technical solution, several third and fourth supporting steel pipes are vertically fixed to support the second protective net, which plays the role of a vertical barrier, can protect people and objects from falling, and further enhance the protective effect of the construction site.

[0018] Preferably, a second fastener is provided between the first supporting steel pipe, the first protective net support assembly, and the fourth supporting steel pipe, and the first supporting steel pipe, the first protective net support assembly, and the fourth supporting steel pipe are fixedly connected by the second fastener.

[0019] By adopting the above technical solution, a stable connection is achieved between the first supporting steel pipe, the first protective net support component, and the fourth supporting steel pipe through the second fixing component, further enhancing the stability of the support frame, thereby improving the stability of the entire protective mechanism, ensuring that the protective mechanism can better protect personnel and objects from falling, and guaranteeing the safety of the jump-bed construction method.

[0020] Preferably, a fixing assembly is provided between the first supporting steel pipe and the diagonal bracing steel pipe. The fixing assembly is located on the lower structural plate. The fixing assembly includes a sweeping rod and a ground anchor. The ground anchor is fixed on the lower structural plate. One side of the sweeping rod is fixedly connected to the first supporting steel pipe. The diagonal bracing steel pipe is fixedly connected to the sweeping rod.

[0021] By adopting the above technical solution, the ground-level bracing bar is fixedly connected to the first supporting steel pipe, and the diagonal bracing steel pipe is fixed to the structural slab by ground anchors. Combined with the anchoring effect of the ground anchors on the structural slab, the overturning resistance and horizontal bearing capacity of the protective mechanism are improved.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a protective device for facilitating the skip-containment method of construction. (Refer to...) Figure 1 A protective device for facilitating the skip-construction method is fixed to the construction blocks in the skip-construction method. The skip-construction method divides a large-volume concrete structure that is too long, too wide, and too thick into several independent blocks and constructs them according to the principle of "block planning, block construction, layered pouring, and overall molding". Adjacent blocks are poured at certain intervals, and the internal stress is released when the early performance of the concrete is not yet stable. Finally, the blocks are connected into a whole. In this embodiment, one of the low blocks and the high block above the low block are described.

[0030] A protective device for facilitating the skip-containment construction method includes a structural plate 1 and a protective mechanism. The protective mechanism includes a first protective net 21, a second protective net 22, and a support frame 23. The two structural plates 1 are respectively fixed to the high-level and low-level containers in the skip-containment construction method. The support frame 23 is located on the outside of the construction container in the skip-containment construction method. The two structural plates 1 are vertically distributed, and the support frame 23 is fixed to the structural plates 1. The first protective net 21 is supported to form a horizontal protective barrier, and the second protective net 22 is supported to form a vertical protective barrier. This structure allows the protective device to fully cover the area with the height difference between the containers.

[0031] Furthermore, addressing the limitation of the protection range of traditional full-span scaffolding, the first protective net 21 forms a horizontal protective barrier, and the second protective net 22 forms a vertical protective barrier, achieving full coverage of the construction area and increasing the comprehensive protection for construction personnel, simultaneously preventing both personnel falls and falling objects.

[0032] Secondly, to address the shortcomings of the independent suspended safety net in terms of adaptability, the first protective net 21 and the second protective net 22 can be fixed at an angle by adjusting the height difference between the high-level and low-level blocks. Through the support frame 23, it is ensured that the first protective net 21 and the second protective net 22 are always kept taut, effectively resisting the deformation caused by the impact of concrete pouring and changes in construction load. The support frame 23 is fixedly connected to the structural slab 1, which improves the impact resistance of the first protective net 21 and the second protective net 22 and reduces the safety hazards on the construction site.

[0033] In this embodiment, the structural slab 1 is set as a concrete structural slab 1. In the skip-pour construction method, the concrete structural slab 1 resists the deformation caused by temperature stress, shrinkage stress and external load through reasonable reinforcement and thickness setting. The concrete structural slab 1 can serve as a supporting structure to assist in the subsequent pouring of blocks.

[0034] Reference Figure 2 Furthermore, the support frame 23 is composed of multiple spaced steel pipes. The steel pipes are galvanized steel pipes with a diameter of 48mm. This material is corrosion resistant and can ensure the stability of the support. The galvanized steel pipes are usually cylindrical and have a certain wall thickness to ensure strength. The support frame 23 includes a first support steel pipe 231. One end of the first support steel pipe 231 is fixed to the upper structural plate 1, and the other end is fixedly connected to the lower structural plate 1. At the same time, the first support steel pipe 231 is fixed to the structural plate 1 through a fixing hole 11 opened on the structural plate 1. The fixing hole 11 is provided with a first fixing member 3, and the first support steel pipe 231 is fixedly connected to the first fixing member 3.

[0035] Reference Figure 3Specifically, the first supporting steel pipe 231 is fixed to the structural plate 1 using the post-anchoring method. The first fixing member 3 is set as an anchor bolt. After the structural plate 1 has been poured, a fixing hole 11 is drilled in the structural plate 1. The diameter of the fixing hole 11 is larger than that of the anchor bolt, and the depth of the fixing hole 11 must meet the anchor bolt embedding length requirements. Then, the dust and debris in the fixing hole 11 are cleaned, the anchor bolt is inserted into the fixing hole 11, and it is rotated and tightened to expand the anchor bolt, thus connecting the first supporting steel pipe 231 to the anchor bolt.

[0036] Furthermore, the supporting frame 23 also includes a first protective net support assembly, which comprises several diagonal bracing steel pipes 235, several second supporting steel pipes 232, and several third supporting steel pipes 233. The diagonal bracing steel pipes 235 are fixedly connected to the lower structural plate 1. The diagonal bracing steel pipes 235 are inclined at a certain angle toward the outside of the construction block of the skip-section construction method. This angle is less than 30 degrees, which allows the center of gravity of the diagonal bracing steel pipes 235 to be closer to the structural plate 1, effectively suppressing the lateral displacement tendency of the diagonal bracing steel pipes 235 caused by excessive inclination, and enhancing the anti-overturning ability.

[0037] Meanwhile, the middle part of the diagonal bracing steel pipe 235 is fixedly connected to the first supporting steel pipe 231, several second supporting steel pipes 232 are perpendicular to the first supporting steel pipe 231, several second supporting steel pipes 232 are distributed perpendicularly along the length of the second supporting steel pipe 232, several second supporting steel pipes 232 are parallel to each other, several second supporting steel pipes 232 are fixedly connected to the first supporting steel pipe 231 on the side near the construction block, several second supporting steel pipes 232 are perpendicularly connected to several third supporting steel pipes 233 on the other side, and the top of the diagonal bracing steel pipe 235 is fixedly connected to several second supporting steel pipes 232 and several third supporting steel pipes 233. This connection relationship enhances the overall stability.

[0038] Specifically, the first protective net 21 is located between the structural plate 1 and the third supporting steel pipe 233. One side of the first protective net 21 is fixedly connected to the structural plate 1, and the other side is fixedly connected to the third supporting steel pipe 233. The first protective net 21 is a large-mesh net made of nylon with a mesh size of 50mm × 50mm. The first protective net 21 and the third supporting steel pipe 233 are fixed by wrapping galvanized steel wire 6 around them, which is simple to operate and ensures the reliability of the connection. Furthermore, the structural plate 1 and the first protective net 21 are also fixed by the first fastener 3. A fixing hole 11 is formed by drilling a hole in the structural plate 1. The depth must meet the embedding requirements of the first fastener 3. The first fastener 3 is inserted into the fixing hole 11, screwed into the hole, and the first protective net 21 is tied and fixed to the first fastener 3 with galvanized steel wire 6.

[0039] Meanwhile, the supporting frame 23 also includes several fourth supporting steel pipes 234, several third supporting steel pipes 233, and several fourth supporting steel pipes 234 vertically fixed to support the second protective net 22. The second protective net 22 is set as a flame-retardant dense mesh safety net with a mesh density of not less than 2000 meshes / 100cm². The second protective net 22 is fixed to the fourth supporting steel pipes 234 by binding the second protective net 22 to the fourth supporting steel pipes 234 with galvanized steel wire 6.

[0040] Furthermore, a fixing component 5 is provided between the first supporting steel pipe 231 and the diagonal bracing steel pipe 235. The fixing component 5 is located on the lower structural plate 1. The fixing component 5 includes a sweeping rod 51 and a ground anchor 52. The ground anchor 52 is fixed inside the structural plate 1. One side of the sweeping rod 51 is fixedly connected to the first supporting steel pipe 231, and the other side of the sweeping rod 51 is fixedly connected to the diagonal bracing steel pipe 235. The diagonal bracing steel pipe 235 and the sweeping rod 51 are fixed to the structural plate 1 by the ground anchor 52. The sweeping rod 51 is generally a horizontally set steel pipe, which can increase the stability of the bottom of the protective mechanism. The ground anchor 52 penetrates into the interior of the structural plate 1, which plays a fixing role and reduces the displacement of the entire protective mechanism.

[0041] On the other hand, a second fastener 4 is provided between the first supporting steel pipe 231, the first protective net support assembly and the fourth supporting steel pipe 234, and the first supporting steel pipe 231, the first protective net support assembly and the fourth supporting steel pipe 234 are fixedly connected by the second fastener 4.

[0042] Specifically, the second fastener 4 is configured as a fastener, which includes right-angle fasteners and swivel fasteners. Right-angle fasteners are used for connecting perpendicularly intersecting steel pipes, while swivel fasteners are suitable for connecting steel pipes at any angle. The angle can be adjusted to adapt to complex construction needs, and they have strong torsional resistance. Furthermore, right-angle fasteners are used to fix the first support steel pipe 231, the second support steel pipe 232, the third support steel pipe 233, the third support steel pipe 233, and the fourth support steel pipe 234, and swivel fasteners are used to fix the diagonal bracing steel pipe 235, the first support steel pipe 231, the diagonal bracing steel pipe 235, the second support steel pipe 232, the diagonal bracing steel pipe 235, and the third support steel pipe 233.

[0043] The implementation principle of a protective device for facilitating the skip-pile construction method according to an embodiment of this application is as follows: The support frame is installed on the completed concrete slab using the post-anchoring method. The support frame consists of several galvanized steel pipes. After the support frame is installed, it supports the first protective net to form a horizontal protective barrier, and the support frame supports the second protective net to form a vertical protective barrier.

[0044] A large-mesh net is installed between the structural slab and the third supporting steel pipe as the first protective net. One side of the first protective net is fixed to the structural slab, and the other side of the first protective net is fixed to the third supporting steel pipe, ensuring that the first protective net is taut and adaptable to the protection needs of areas with elevation differences.

[0045] Meanwhile, a second protective net consisting of flame-retardant dense mesh safety netting is installed on the outside of the construction block. Vertical protection is achieved through the vertical fixation of the third and fourth supporting steel pipes. The second protective netting is fixed to the fourth supporting steel pipe. To enhance overall stability, the diagonal bracing steel pipes are inclinedly connected to the lower structural plate. The diagonal bracing steel pipes are fixed to the first supporting steel pipe at the middle, the second supporting steel pipe at the top, and the third supporting steel pipe at the intersection. The diagonal bracing steel pipes are fixedly connected to the ground sweeping rods. The diagonal bracing steel pipes and the ground sweeping rods are anchored to the structural plate by ground anchors. Each node of the support frame is connected by right-angle couplers and swivel couplers. Right-angle couplers are used for the rigid fixation of vertically intersecting steel pipes, while swivel couplers are used to adapt to non-vertical connections of steel pipes at any angle, ensuring the overall torsional and overturning resistance of the structure.

[0046] Ultimately, through the synergistic effect of the protective netting and the supporting frame, the limited protection range of traditional full-span scaffolding is addressed. The first protective netting forms a horizontal protective barrier, and the second protective netting forms a vertical protective barrier, achieving full coverage of the construction area. This increases the comprehensive protection for construction workers and can simultaneously prevent both falls and falling objects.

[0047] Secondly, addressing the shortcomings of independently suspended safety nets in adapting to changes in height difference between high and low blocks, the first and second protective nets can be adjusted to a fixed angle based on the height difference between the high and low blocks. Through the support frame, the first and second protective nets are ensured to always remain taut, effectively resisting deformation caused by concrete pouring impact and changes in construction load. The support frame is fixedly connected to the structural slab, improving the impact resistance of the first and second protective nets and reducing safety hazards at the construction site.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
