Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a tower crane access system. Background Technology

[0002] As a mainstream building structure, steel structure buildings exhibit unique advantages over traditional concrete structures in terms of material performance, construction efficiency, and environmental benefits. Tower cranes, a common lifting device in construction projects, require operators to climb standard sections to reach the cab during their commute. This is particularly problematic for high-rise steel structure buildings, where construction is efficient and fast. As the main structure increases in number of layers, the number of standard sections that operators need to climb increases, increasing physical exertion and operational risks. Therefore, reducing the climbing height required for tower crane operators and maintenance personnel in high-rise steel structure projects and designing suitable access devices for tower cranes in such buildings are urgent research directions for construction companies.

[0003] Related technologies, such as Chinese patent CN208218272U, disclose a conventional tower crane access passage: It comprises a base, railings, and a base plate; the base includes a floor end fixed section whose outer end is fixed to the main structure; the two ends of a first connecting rod are respectively inserted into the inner end of the floor end fixed section and one end of an adjusting section; the two ends of a second connecting rod are respectively inserted into the other end of the adjusting section and the inner end of the tower crane end fixed section; the outer end of the tower crane end fixed section is connected to a standard tower crane section; the railings include left and right railings with corresponding horizontal bars; the vertical bar at the outer end of the left railing is connected to the floor end fixed section; the two ends of a third connecting rod are respectively inserted into the hollow horizontal bars of the left and right railings; the floor end fixed section, the first connecting rod, the adjusting section, the second connecting rod, the tower crane end fixed section, the horizontal bars of the left and right railings, and the third connecting rod are each provided with multiple adjusting holes, and bolts are installed in the corresponding adjusting holes at the connection points. During installation, the aforementioned structure uses columns directly inserted into the floor slab to fix the passageway to the floor. The compatibility of the column material with the concrete is unknown. Dismantling the passageway requires cutting the columns, which damages both the slab surface and the passageway itself. Utility Model Content

[0004] In view of this, the present invention provides a tower crane access system to solve the problems of related technologies where, during installation, the access is fixed to the floor by directly inserting columns into the floor slab, the compatibility of the column material with the concrete is unknown, the access needs to be dismantled by cutting the columns, and damage is caused to the slab surface and the access itself.

[0005] In a first aspect, this utility model provides a tower crane access system, comprising:

[0006] Floor slabs, wherein the floor slabs are arranged at intervals from the tower crane sections;

[0007] An embedded component assembly, wherein the embedded component assembly is installed on the floor slab;

[0008] A support structure, which is detachably mounted on the embedded parts assembly;

[0009] A channel structure, one end of which is mounted on the support structure and the other end is fixed to a tower crane section.

[0010] Beneficial Effects: By installing a passageway structure between the floor slab and the tower crane section, with a pedestrian walkway for workers, the problem of safe and convenient passage between the tower crane and the floor is solved. Workers can directly reach the corresponding tower crane section from the floor slab, avoiding the risks associated with directly climbing the standard tower crane section. The support structure is detachably installed on the embedded parts assembly. Dismantling allows for direct separation of the support structure and embedded parts, avoiding cutting damage compared to existing technologies and preserving the surface structure of the floor slab. Furthermore, the same support structure can be reused at multiple construction sites, reducing repeated construction costs. The embedded parts assembly is pre-embedded in the floor slab and then fixed with poured concrete, significantly enhancing the stability of the entire system.

[0011] In one alternative implementation, the embedded parts group includes a plurality of embedded parts;

[0012] Several support feet in the support structure can be installed on the corresponding embedded parts.

[0013] In one alternative implementation, two support structures are provided, and the two support structures are spaced apart along a first direction.

[0014] In one alternative implementation, the support structure includes:

[0015] The first support rod has a support foot at its bottom end installed on an embedded part on the side of the floor slab near the passage structure, and the first support rod is arranged vertically.

[0016] In one optional embodiment, the support structure further includes: a second support rod and a connecting rod, wherein the support foot at the bottom end of the second support rod is disposed on an embedded part away from the channel structure, and the second support rod is arranged vertically;

[0017] One end of the connecting rod is connected to the first support rod, and the other end is connected to the second support rod.

[0018] Beneficial Effects: With the above configuration, the two support structures are spaced apart and symmetrically arranged along the first direction. The two ends of the channel structure away from the tower crane section are fixed to the first support rods of the two support structures respectively. This design ensures that the load is evenly distributed on both sides of the channel structure, reducing the risk of tilting or twisting due to uneven force on one side. Each support structure is anchored to different positions on the floor slab by two support rods, expanding the width of the support base. Combined with the rigid frame formed by the two connecting rods, this structure effectively resists lateral forces and improves the stability of the support device. Each support structure is installed on two embedded parts, and the bottom ends of the support rods are fixed by support feet, which can distribute the channel load to multiple embedded parts, avoiding stress concentration in a single embedded part or floor slab area, and reducing the risk of floor slab damage.

[0019] In one alternative implementation, the channel structure includes:

[0020] The base has one end connected to the tower crane section and the other end, away from the tower crane section, fixed to the first support rod.

[0021] The guardrail is vertically and fixedly installed on the side of the base;

[0022] The base and the guardrail together form a pedestrian walkway.

[0023] In one alternative implementation, the base is arranged horizontally overall.

[0024] In an alternative embodiment, the passageway structure further includes a staircase installed between the two support structures, the top of the staircase being fixed to the first support rod, and the bottom of the staircase resting on the floor slab.

[0025] In one alternative embodiment, the channel structure further includes a diagonal brace, one end of which is fixed to the base and the other end of which is fixed to the first support rod.

[0026] In one alternative embodiment, the passageway structure further includes a passageway gate fixed to the side of the guardrail away from the tower crane section, the passageway gate being used to close or open the pedestrian passageway.

[0027] Beneficial Effects: With the above configuration, the base is horizontally positioned between the tower crane section and the supporting structure, serving as the primary load-bearing surface. This directly creates a stable horizontal walking passage connecting the tower crane and the floor. Two guardrails form a continuous physical barrier on both sides of the passage, preventing accidental falls by personnel and improving safety. The addition of stairs allows workers to safely and conveniently ascend and descend the passage; the stairs' inclination aligns with the connecting rod, allowing workers to hold onto the connecting rod while climbing, further enhancing safety. The diagonal bracing forms a triangular support structure between the base and the first supporting rod, improving the overall rigidity and stability of the passage. Attached Figure Description

[0041] As a mainstream building structure, steel structure buildings exhibit unique advantages over traditional concrete structures in terms of material performance, construction efficiency, and environmental benefits. Tower cranes, a common lifting device in construction projects, require operators to climb standard sections to reach the cab during their commute. This is particularly problematic for high-rise steel structure buildings, where construction is efficient and fast. As the main structure increases in number of layers, the number of standard sections that operators need to climb increases, increasing physical exertion and operational risks. Therefore, reducing the climbing height required for tower crane operators and maintenance personnel in high-rise steel structure projects and designing suitable access devices for tower cranes in such buildings are urgent research directions for construction companies.

[0042] Related technologies, such as Chinese patent CN208218272U, disclose a conventional tower crane access passage: It comprises a base, railings, and a base plate; the base includes a floor end fixed section whose outer end is fixed to the main structure; the two ends of a first connecting rod are respectively inserted into the inner end of the floor end fixed section and one end of an adjusting section; the two ends of a second connecting rod are respectively inserted into the other end of the adjusting section and the inner end of the tower crane end fixed section; the outer end of the tower crane end fixed section is connected to a standard tower crane section; the railings include left and right railings with corresponding horizontal bars; the vertical bar at the outer end of the left railing is connected to the floor end fixed section; the two ends of a third connecting rod are respectively inserted into the hollow horizontal bars of the left and right railings; the floor end fixed section, the first connecting rod, the adjusting section, the second connecting rod, the tower crane end fixed section, the horizontal bars of the left and right railings, and the third connecting rod are each provided with multiple adjusting holes, and bolts are installed in the corresponding adjusting holes at the connection points. During installation, the aforementioned structure uses columns directly inserted into the floor slab to fix the passageway to the floor. The compatibility of the column material with the concrete is unknown. Dismantling the passageway requires cutting the columns, which damages both the slab surface and the passageway itself.

[0043] To solve the above technical problems, the following will be combined with... Figures 1 to 4 The following describes embodiments of the present invention.

[0044] According to an embodiment of the present invention, a tower crane access system is provided, comprising: a floor slab 1, a tower crane section 2, an embedded component assembly, a support structure 4, and an access structure 5.

[0045] like Figure 1 As shown, the tower crane is arranged vertically, and floor slab 1 is arranged horizontally on one side of the tower crane. Floor slab 1 and the tower crane are arranged at intervals, with a certain distance between them. Embedded parts are embedded in floor slab 1, and support structure 4 is detachably installed on the embedded parts. One end of passage structure 5 is installed on support structure 4, and the other end is fixed to tower crane section 2. Passage structure 5 has a pedestrian walkway for workers.

[0046] Through the above configuration, a passageway structure 5 is installed between the floor slab 1 and the tower crane section 2. This passageway structure 5 provides a pedestrian walkway for workers, solving the problem of safe and convenient passage between the tower crane and the floor. Workers can directly access the corresponding tower crane section 2 from the floor slab 1, avoiding the risks associated with directly climbing the tower crane. The support structure 4 is detachably installed on the embedded parts assembly. Dismantling allows for direct separation of the support structure 4 and the embedded parts 3, avoiding cutting damage compared to existing technologies and preserving the surface structure of the floor slab 1. Furthermore, the same support structure 4 can be reused at multiple construction sites, reducing the cost of repeated construction. The embedded parts assembly is pre-embedded in the floor slab 1 and then fixed with poured concrete, significantly enhancing the stability of the entire system.

[0047] In this embodiment, as Figure 1 and Figure 2 As shown, the embedded parts group includes several embedded parts 3. Specifically, each support structure 4 has four support feet, so four embedded parts 3 support one support structure 4. The four embedded parts 3 are arranged in a rectangular shape from a top view. Two embedded parts 3 are installed on the edge of the floor slab 1 near the end of the tower crane section 2, and the other two embedded parts 3 are installed on the inner side of the floor slab 1.

[0048] Two support structures 4 are provided, and the two support structures 4 are spaced apart along the first direction, which is... Figure 2 The two supporting structures are symmetrically arranged in the left and right directions. Figure 2From a top-down perspective, one support structure 4 is installed on two embedded parts 3 in the left column, and the other support structure 4 is installed on two embedded parts 3 in the right column. Taking one of the support structures 4 as an example, its specific structure includes: a first support rod 41, a second support rod 42, and a connecting rod 43. The support foot at the bottom of the first support rod 41 is installed on one of the embedded parts 3 near the edge of the floor slab 1 in the corresponding column, close to the passage structure 5. The entire first support rod 41 is vertically arranged. The second support rod 42 corresponds to the first support rod 41, and its support foot is installed on one of the embedded parts 3 on the inner side of the floor slab 1 away from the passage structure 5 in the corresponding column. The second support rod 42 is also vertically arranged. The length of the second support rod 42 is less than the length of the first support rod 41. There are two connecting rods 43. One of the connecting rods 43 is connected to the top of the first support rod 41 and the top of the second support rod 42 at both ends, respectively. The other connecting rod 43 is installed parallel to the bottom of the connecting rod 43, and its two ends are also connected to the first support rod 41 and the second support rod 42 at both ends.

[0049] With the above arrangement, the two support structures 4 are spaced apart and symmetrically arranged along the first direction, and the two ends of the channel structure 5 on the side away from the tower crane section 2 are respectively fixed to the first support rods 41 of the two support structures 4. This design ensures that the load is evenly distributed on both sides of the channel structure 5, reducing the risk of tilting or twisting caused by uneven force on one side. Each support structure 4 is anchored to different positions on the floor slab 1 by two support rods, expanding the width of the support base. Combined with the rigid frame formed by the two connecting rods 43, this structure can effectively resist lateral forces and improve the stability of the support device. Each support structure 4 is installed on two embedded parts 3, and the bottom end of the support rod is fixed by a support foot, which can distribute the channel load to multiple embedded parts 3, avoiding stress concentration in a single embedded part 3 or the area of ​​the floor slab 1, and reducing the risk of damage to the floor slab 1.

[0050] like Figure 1 and Figure 2 As shown, the passage structure 5 includes: a base 51, a guardrail 52, a staircase 53, diagonal bracing 54, and a passage door 55. The base 51 is a threaded steel pipe, and it is horizontally arranged between the tower crane section 2 and the supporting structure 4. Figure 1As shown, the left side of the base 51 is connected to the tower crane section 2. For example, an ear plate can be installed on the left side of the base 51, and the right-angle structure formed by the ear plate and the base 51 is secured to the steel rib of the tower crane section 2. The front and rear ends of the right side of the base 51 are fixed to two first support rods 41. For example, mounting holes can be opened on the first support rods 41, and bolts can be welded to the front and rear ends of the right side of the base 51. After the bolts pass through the mounting holes, they are fixed with nuts. Two guardrails 52 are provided. The extension direction of the guardrails 52 is consistent with the length direction of the base 51. A single guardrail 52 is vertically fixed to the side of the base 51, and the entire guardrail 52 is located above the base 51. The two guardrails 52 are symmetrically installed on both sides of the base 51 along the first direction. The base 51 and the guardrails 52 form a pedestrian passage. The staircase 53 is installed between the two support structures 4. The top of the staircase 53 is fixed to the first support rod 41, and the bottom of the staircase 53 rests on the floor slab 1. The inclination direction of the staircase 53 is consistent with the inclination direction of the connecting rod 43. The diagonal brace 54 is installed at an angle, with one end fixed to the base 51 and the other end fixed to the first support rod 41. The passage door 55 is fixed to the side of the guardrail 52 away from the tower crane section 2. The passage door 55 is installed on one end of the guardrail 52 away from the tower crane section 2 by a hinge. A door lock is provided between the passage door 55 and the other guardrail 52. The passage door 55 is used to close or open the pedestrian passage.

[0051] With the above configuration, the base 51 is horizontally positioned between the tower crane section 2 and the supporting structure 4, serving as the main load-bearing surface. This directly constructs a stable horizontal walking passage connecting the tower crane and the floor. Two guardrails 52 form continuous physical barriers on both sides of the walking passage, preventing accidental falls by personnel and improving passage safety. A staircase 53 allows workers to safely and conveniently ascend and descend the passage. The inclination direction of the staircase 53 is consistent with that of the connecting rod 43, allowing workers to hold onto the connecting rod 43 while ascending, further enhancing safety. The diagonal brace 54 forms a triangular supporting structure 4 between the base 51 and the first supporting rod 41, improving the overall rigidity and stability of the passage.

[0052] In this embodiment, as Figure 4 As shown, the floor slab 1 includes a steel truss plate 11 and a triangular steel truss 12. The triangular steel truss 12 is welded to the steel truss plate 11, and the bottom end of the embedded part 3 is welded to the steel truss plate 11. Concrete is then poured to provide double fixation for the embedded part 3 by the floor slab 1, thereby improving the stability of the embedded part 3. The embedded part 3 is generally sleeve-shaped, with a pin opening at the top. The pin opening is located above the concrete pouring layer. When installing the support structure 4, the support feet at the lower ends of the first support rod 41 and the second support rod 42 also have connection openings corresponding to the pin openings. The lower ends of the first support rod 41 and the second support rod 42 are inserted into the embedded part 3, and the pins pass through the pin openings and connection openings to achieve fixation between the two.

[0053] In this embodiment, as Figure 1 As shown, a supporting angle steel 6 is welded below the staircase 53. The lower end of the supporting angle steel 6 abuts against the upper surface of the floor slab 1, providing stable and reliable support for the staircase 53.
