Description

Technical Field

[0001] The utility model belongs to the field of building construction, and in particular relates to a progressive construction platform at the lower side of a plank road. Background Art

[0002] In the field of construction, the maintenance of steel structures such as plank roads and trails is an important part of ensuring their safety and extending their service life. After the construction of these structures is completed, they usually need to be inspected and maintained regularly. In particular, the steel structure under the plank road is more complicated to maintain due to its special location.

[0003] Traditional maintenance methods include using aerial platforms, which can directly reach the underside of the plank road for maintenance. However, this method is limited by the roads below the plank road, especially in narrow or busy areas, where the use of aerial platforms is greatly restricted. In addition, the cost of using aerial platforms is relatively high, which increases the economic burden of maintenance work.

[0004] Another maintenance method is to use a hanging basket, which requires a car to lift. Although this method can reduce the impact on the road below, it also has its limitations. For example, the construction site needs enough space to place the car crane, and the stability and safety of the hanging basket also need special attention. In addition, the construction schedule also needs to take into account the complexity and time consumption of the lifting operation.

[0005] Therefore, it is urgent to design a progressive construction platform under the plank road. Utility Model Content

[0036] The present invention is further described and illustrated below in conjunction with the accompanying drawings and specific implementations. The technical features of each implementation of the present invention can be combined accordingly without conflicting with each other.

[0037] like Figure 1 As shown, in a preferred embodiment of the utility model, a progressive construction platform under a plank road is provided. The progressive construction platform is arranged under the plank road platform and mainly consists of a plurality of lower hanging units 1, a platform cross beam 2 and a frame plate 3.

[0038] The hanging unit 1 provided in this embodiment is as follows Figure 2 As shown. Each lower hanging unit 1 includes an upper crossbeam 1-1, an adjustment component 1-2, a lower crossbeam 1-3, a basket bolt 1-4, a lower hanging rod 1-5 and a fixing groove 1-6. Connection holes for connecting the adjustment component 1-2 are provided at both ends of the upper crossbeam 1-1 and the lower crossbeam 1-3. A plurality of adjustment holes are longitudinally provided on the adjustment component 1-2, and the adjustment component 1-2 is vertically arranged at both ends of the upper crossbeam 1-1 and the lower crossbeam 1-3 through the fixing parts passing through the different adjustment holes on the adjustment component 1-2 and the connection holes at both ends of the upper crossbeam 1-1 and the lower crossbeam 1-3. The adjustment component 1-2 is detachably connected to the upper crossbeam 1-1 and the lower crossbeam 1-3, and the spacing between the upper crossbeam 1-1 and the lower crossbeam 1-3 is adjusted so as to be arranged on different plank road steel beams 4.

[0039] In this embodiment, the upper crossbeam 1-1, the adjustment component 1-2 and the lower crossbeam 1-3 are all made of steel plates, but those skilled in the art may also use other steels such as round steel, square steel pipe, angle steel or channel steel which are more common in the construction site according to the actual working conditions.

[0040] like Figure 1 As shown, the plank road platform is composed of a plurality of parallel plank road steel beams 4. In this embodiment, a plurality of the above-mentioned lower hanging units 1 are arranged at intervals on each plank road steel beam 4. A connector 1-7 for connecting the flower basket bolts 1-4 is fixed below the lower cross beam 1-3 of the lower hanging unit 1. In this embodiment, the connector 1-7 is made of U-shaped round steel, and the U-shaped round steel is fixed below the lower cross beam 1-3 by welding. Those skilled in the art may also use other forms of connectors, as long as they can be used to connect the hooks on the flower basket bolts 1-4.

[0041] Turnbuckles, also known as rigging turnbuckles, are a commonly used component in construction. Figure 2As shown in , the flower basket bolt 1-4 provided in this embodiment includes a hook at the top and an adjustment structure at the bottom. The top and bottom of the adjustment structure are holes with internal threads. The hook is hung on the connecting piece 1-7, and the bottom is fixed to the top of the adjustment structure by a threaded connection. The upper part of the lower hanging rod 1-5 is provided with an external thread, and is fixed to the bottom of the adjustment structure by a threaded connection. By adjusting the threaded connection between the lower hanging rod and the flower basket bolt, the posture adjustment of the construction platform is achieved to ensure that the platform is in a horizontal state. A fixing groove 1-6 is fixed to the bottom of each lower hanging rod 1-5.

[0042] like Figure 3 As shown, each platform beam 2 provided in this embodiment includes a fixing rod 2-1 and a load-bearing beam 2-2; the load-bearing beam 2-2 is arranged parallel to the plank road steel beam 4, and is placed in a fixing groove 1-6 at the bottom of the lower hanging unit 1 arranged on the plank road steel beam 4. A plurality of frame plates 3 are laid on adjacent load-bearing beams 2-2, and the frame plates 3 are laid perpendicular to the arrangement direction of the load-bearing beams 2-2. In order to fix the frame plates 3, a fixing rod 2-1 is arranged above each load-bearing beam 2-2. The fixing rod 2-1 is placed parallel to the load-bearing beam 2-2. Bolt holes are provided at both ends of the fixing rod 2-1 and the load-bearing beam 2-2, and are fixed by bolt connection.

[0043] Since the load-bearing beam 2-2 is usually a square steel pipe, in this embodiment, the fixing groove 1-6 is a U-shaped groove formed by welding steel plates or directly using channel steel. In order to limit the load-bearing beam 2-2, a limiting rod is provided between the vertical plates on both sides of the fixing groove 1-6. Specifically, bolt holes are provided on the vertical plates on both sides of the fixing groove 1-6, and the load-bearing beam 2-2 is limited by setting bolts.

[0044] It should be noted that the frame board 3 can be a wooden springboard or a finished scaffolding board. The wooden springboard is a commonly used temporary turnover material in the field of construction. It is mainly used on scaffolds or operating frames to provide a stable surface for workers to walk on, transfer materials and perform construction work. Those skilled in the art can determine the specifications and dimensions of the wooden springboard according to actual on-site needs.

[0045] like Figure 4 As shown, a limit plate 2-3 for limiting the position of the fixing groove 1-6 is also provided below the load-bearing beam 2-2. The size of the limit plate 2-3 matches the fixing groove 1-6 to prevent the load-bearing beam 2-2 from sliding.

[0046] In another preferred embodiment of the present invention, a construction method using the above-mentioned progressive construction platform is provided, which is as follows:

[0047] (1) Figure 5 As shown, the lower hanging unit 1 is arranged on the plank road steel beam 4 of the plank road platform, so that a plurality of lower hanging units 1 are arranged in the transverse direction and the longitudinal direction of the plank road platform.

[0048] (2) Figure 6 As shown, the load-bearing beam 2-2 is placed in the fixing groove 1-6 of the lower hanging unit 1, and each load-bearing beam 2-2 is arranged parallel to the plank road steel beam 4; after the placement is completed, the bolts are passed through the bolt holes opened in the vertical plates on both sides of the fixing groove 1-6 to limit the load-bearing beam 2-2.

[0049] (3) Figure 7 As shown, the wooden springboard is laid on the load-bearing beam 2-2, and the laying direction is perpendicular to the direction of the load-bearing beam 2-2. A fixing rod 2-1 is set above each load-bearing beam 2-2, and the fixing rod 2-1 and the two sides of the load-bearing beam 2-2 are fixedly connected by bolts to tightly fix the wooden springboard between the load-bearing beam 2-2 and the fixing rod 2-1. After the installation is completed, the maintenance work on the bottom surface of the plank road platform can be carried out.

[0050] (4) Figure 8 As shown, after the maintenance work on the bottom surface of the plank road platform at the rear is completed, the lower hanging unit 1 at the corresponding position is removed.

[0051] (5) Fig. 9 As shown, push the wooden springboard one construction distance in the construction direction.

[0052] (6) Fig.10 As shown, with the help of the cantilevered wooden springboard in the construction forward direction, the lower hanging unit 1 at the corresponding position is reinstalled to realize the forward movement of the side progressive construction platform. This process is repeated until the maintenance work on the bottom surface of the plank road platform is completed.

[0053] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
