Description

Technical Field

[0001] The utility model relates to the technical field of plank road reinforcement, in particular to a cantilevered operating platform device for reinforcing a cantilevered plank road. Background Art

[0002] As the existing mountain cantilevered plank road has grown in use over the years, some of its components have been damaged, causing it to be listed as a historical structure and requiring reinforcement and renovation. This renovation project faces multiple challenges.

[0003] The original appearance needs to be protected: the reinforcement and renovation work must ensure that the original historical style and appearance characteristics of the cantilevered plank road are not changed. This is a respect and protection for the historical building.

[0004] No impact on normal use: The plank road must still maintain its original function during the reinforcement process and its function as a passage must not be interrupted or affected by the construction.

[0005] Complex terrain restrictions: The plank road is built on the mountain, and the terrain is uneven, making it difficult to carry out reinforcement work according to conventional utility models. The specific location, height, width and number of stair steps of the plank road are subject to strict usage requirements, further increasing the difficulty of construction.

[0006] High-demand reinforcement operating platform: Due to the complexity of the location of the plank road, the demand for a reinforced operating platform is extremely high. Traditional reinforcement technology and equipment cannot meet the construction needs in this complex environment, especially in local reinforcement.

[0007] Based on the above factors, an effective cantilevered plank road ladder beam reinforcement cantilevered operating platform device is needed to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to solve the technical problems existing in the reinforcement of cantilevered plank roads in the prior art, and to provide a cantilevered operating platform device for reinforcing cantilevered plank roads.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A cantilever operating platform device for reinforcing a cantilevered plank road comprises a plurality of cantilevered H-shaped steels, wherein a steel embedded plate is fixed at one end of the plurality of cantilevered H-shaped steels, the steel embedded plate is provided with holes, and anchor rods are installed in the holes, and the anchor rods are embedded in the mountain body. A platform frame structure is provided on the cantilevered H-shaped steels, and the platform frame structure comprises two upper and lower groups of parallel first reinforcement rods, and the upper first reinforcement rods are fixed to the cantilevered H-shaped steels, and the platform frame structure further comprises two upper and lower groups of parallel inclined reinforcement rods obliquely arranged below the first reinforcement rods, and a longitudinal hanger is connected between the inclined reinforcement rods and the first reinforcement rods.

[0011] Furthermore, a plurality of prestressed steel cables are provided between the first reinforcement rod located at the upper portion and the inclined reinforcement rod located at the lower portion.

[0012] Furthermore, each group of the first reinforcing rods includes two first reinforcing rods arranged in parallel on the left and right sides, and a transverse rod is connected between the two first reinforcing rods on the left and right sides.

[0013] Furthermore, each group of the inclined reinforcement rods includes two inclined reinforcement rods arranged in parallel on the left and right sides, and a transverse rod is connected between the two inclined reinforcement rods on the left and right sides.

[0014] Furthermore, the first reinforcement rod, the longitudinal suspension rod and the inclined reinforcement rod are connected by connecting fasteners.

[0015] Furthermore, two adjacent cantilevered H-shaped steels are connected via a connecting plate, and high-strength bolts are installed on the connecting plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Simple and efficient structure: This utility model avoids complex structures and tedious installation processes. By assembling steel sections in sections and partially hanging a detachable operating platform, the entire structure is simple and efficient. This design is not only easy to implement, but also reduces the difficulty of installation and disassembly, improving work efficiency.

[0018] 2. Save time and labor: The use of segmented assembly and partial suspension greatly reduces construction time and labor requirements. Construction workers can quickly complete tasks such as anchor rod placement, steel installation, and scaffolding erection, thereby shortening construction time and reducing construction costs.

[0019] 3. Adapt to local conditions: This new model fully utilizes the natural support of the mountain, eliminating the need for additional support structures. Furthermore, the position of anchor rods, the specifications of steel sections, and the layout of scaffolding can be flexibly adjusted according to the actual conditions of the mountain and the specific requirements of the plank road reinforcement to ensure the best reinforcement effect.

[0020] 4. Improve the speed of reinforcement: By adopting this utility model, construction workers can quickly build a stable and reliable operating platform, providing strong support for the reinforcement work of the cantilevered plank road. This not only speeds up the reinforcement speed, but also ensures the continuity and efficiency of the reinforcement work.

[0021] 5. Reduce reinforcement costs: Since the utility model avoids the need for complex structures and additional supporting materials, it can significantly reduce reinforcement costs. At the same time, due to the increased reinforcement speed, it can further reduce labor costs and equipment rental costs during construction.

[0022] 6. Improved reinforcement quality: This new model ensures the stability and safety of the operating platform through precise positioning and setting out, stable anchor bolt installation, and reliable steel connection. This provides a good working environment for construction workers, allowing them to focus more on the plank road reinforcement work, thereby improving the reinforcement quality.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, a cantilever operating platform device for cantilever plank road reinforcement includes several cantilever H-shaped steels 1. Two adjacent cantilever H-shaped steels 1 are connected by a connecting plate 9, and high-strength bolts are installed on the connecting plate 9. One end of the several cantilever H-shaped steels 1 is welded and fixed with a steel embedded plate 2. The steel embedded plate 2 is provided with a hole, and the hole is equipped with a rebar anchor rod 3. The rebar anchor rod 3 is embedded in the mountain. A platform frame structure is provided on the cantilever H-shaped steel 1. The platform frame structure includes two upper and lower groups of parallel first reinforcing rods 4. Each group of first reinforcing rods 4 includes two first reinforcing rods 4 arranged parallel to each other on the left and right. A transverse rod is tied between the left and right first reinforcing rods 4. The upper first reinforcing rod 4 is welded and fixed to the cantilever H-shaped steel 1. The platform frame structure also includes two upper and lower groups of parallel inclined reinforcing rods 6 arranged obliquely below the first reinforcing rods 4, and a longitudinal hanger rod 5 is tied between the inclined reinforcing rods 6 and the first reinforcing rods 4. Each set of inclined reinforcement rods 6 consists of two parallel, horizontally arranged inclined reinforcement rods 6, with a transverse rod connecting them. Several prestressed steel cables 8 are installed between the upper first reinforcement rod 4 and the lower inclined reinforcement rod 6. Fasteners 7 connect the first reinforcement rod 4, longitudinal boom 5, and inclined reinforcement rods 6.

[0030] The specific working process of this utility model is as follows:

[0031] As shown in the figure, a represents the cantilevered plank road ladder beam, b represents the mountain, 10 represents the plank road beam, and 11 represents the plank road stairs. The working principle of the entire utility model cantilevered operating platform device is based on precise positioning and laying out, stable mountain anchor installation, reliable cantilever beam bearing structure and stable operating platform construction.

[0032] Step 1: First, accurately locate and lay out the anchor rods according to the locations where the ladder beams of the plank road need to be reinforced. This is a key step to ensure that the anchor rods can accurately and effectively support the cantilever beams. Drill holes at the laid-out locations. After drilling, use hole cleaning equipment to remove impurities in the holes and ensure that the hole walls are clean and smooth so that the anchor glue can be fully filled and bonded.

[0033] Step 2: Then inject rebar glue into the hole, and then rotate and implant the rebar anchor rod 3. The rebar glue can enhance the bonding force between the rebar anchor rod 3 and the mountain rock, and improve the stability of the rebar anchor rod 3. The exposed part of the rebar anchor rod 3 must meet the subsequent installation requirements to ensure that the cantilever beam can be firmly connected to the anchor rod 3.

[0034] Step 3: Before installing the cantilever H-shaped steel 1, perform a pull-out bearing capacity test on the anchor rod 3 to ensure that the anchor rod 3 can bear the weight of the cantilever beam and the load on it. This is an important step to ensure the safety of the entire device.

[0035] Step 4. Install the cantilever H-shaped steel 1 with the embedded steel plate 2 and tighten the anchor bolts. Then install the second section of the cantilever H-shaped steel 1. The two sections of the cantilever H-shaped steel 1 are connected with connecting plates 9 and high-strength bolts. The high-strength bolts can provide reliable connection strength to ensure the stability of the cantilever beam. Check the exposed threads of the bolts as required to ensure that the bolt connection is tight and reliable.

[0036] Step 5: First, install the two first reinforcement rods 4 on the upper portion of the cantilevered H-beam 1. Then, install the transverse rod between the two first reinforcement rods 4. After installation, install the longitudinal hanger rods 5. The reserved size at the bottom of the longitudinal hanger rods 5 should meet the operation requirements. Transverse rods can be installed between the longitudinal hangers 5 according to actual needs. After the longitudinal hangers 5 are installed, install the lower first reinforcement rods 4. Then, install the inclined reinforcement rods 6. Install the transverse rod between the left and right inclined reinforcement rods 6. Finally, install the prestressed steel cables 8.

[0037] Together, these rods form the framework of the operating platform, providing stable support. The first reinforcement rod 4 is located above the plank walkway stairs 11 and the cantilevered plank walkway ladder beam a, while the inclined reinforcement rod 6 is located below the plank walkway stairs 11 and the cantilevered plank walkway ladder beam a. The cantilevered plank walkway ladder beam a is secured to the mountain via the plank walkway crossbeam 10. The installation of the inclined reinforcement rod 6 improves the overall stability of the operating platform, while the prestressed steel cables 8 further enhance the platform's load-bearing capacity and reduce deformation. These steps collectively ensure the stability and safety of the entire device, providing strong support for the cantilevered plank walkway reinforcement work and a safe and stable operating environment for construction personnel.
