Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a reusable steel waler with a convenient disassembly structure. Background Technology

[0002] Steel walers are a type of supporting component used in building structures, especially in foundation pit support, tunnel engineering, or underground structure construction. They are mainly used to enhance soil stability, prevent soil slippage or collapse, and bear and disperse the effects of earth pressure or other external forces.

[0003] Traditionally, the construction of steel walers typically involves first installing sheet piles, then welding the walers onto them, and finally erecting the transverse support columns. However, this welding method makes the construction process inconvenient and prevents the walers from being reused or rotated, thus requiring improvement. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reusable steel waler with a convenient disassembly structure, which has the effect of reusability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a reusable steel waler with a convenient disassembly structure, comprising:

[0006] Steel sheet piles are vertically inserted into the bottom of the foundation pit in a wavy shape.

[0007] I-beam walers are laterally positioned inside the sheet piles;

[0011] In a preferred embodiment, the present invention can be further configured such that: bolts are horizontally arranged on the I-beam waler, penetrating the support plate and the sheet pile, and both the support plate and the sheet pile are vertically provided with strip holes for the bolts to pass through.

[0012] In a preferred embodiment, the present invention can be further configured such that: a reinforcing plate extends downward from the lower end of the support plate, and a diagonal brace is provided between the reinforcing plate and the hook plate.

[0013] In a preferred embodiment, the present invention can be further configured such that: both ends of the I-beam waler are provided with flanges, and fasteners are provided between the flanges.

[0014] In a preferred embodiment, the present invention can be further configured such that the I-beam waler includes a pair of vertical plates and a connecting plate, wherein the connecting plate is provided in two layers and is arranged laterally between the pair of vertical plates.

[0015] In a preferred embodiment, the present invention can be further configured such that: a reinforcing rib is provided on the outer side of the connecting plate between the pair of vertical plates.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, a reusable steel waler with a convenient disassembly structure includes sheet piles 1 and I-beam walers 2. The sheet piles 1 are vertically inserted into the bottom of the foundation pit in a wavy shape, and the I-beam walers 2 are arranged laterally inside the sheet piles 1 located on the inner side.

[0027] like Figure 1 , Figure 2 As shown, a support plate 3 is provided on the inner side of the sheet pile 1, and a hook plate 31 for supporting the I-beam waler 2 is provided at the lower end of the support plate 3. A reinforcing plate 32 is provided extending downward from the lower end of the support plate 3, and a diagonal brace 33 is provided between the reinforcing plate 32 and the hook plate 31 to increase the structural strength and load-bearing capacity of the hook plate 31.

[0028] like Figure 2 , Figure 3 As shown, a dovetail block 34 is provided on the back side of the support plate 3, and a groove 11 for the dovetail block 34 to be embedded in is provided on the steel sheet pile 1, and a dovetail groove 12 connecting the lower end of the groove 11 and allowing the dovetail block 34 to slide into it.

[0029] like Figure 2 , Figure 3 As shown, the dovetail block 34 is vertically slidably connected to the support plate 3, and the support plate 3 is provided with a drive mechanism 4 for controlling the vertical sliding of the dovetail block 34.

[0030] like Figure 2 , Figure 3 As shown, the drive mechanism 4 includes a drive rod 41 and a handwheel 42. The drive rod 41 is vertically threaded to the support plate 3 and rotatably connected to the upper end of the dovetail block 34. The handwheel 42 is located at the upper end of the drive rod 41.

[0031] like Figure 2 , Figure 3 As shown, bolts 5 are horizontally arranged on the I-beam waler 2, which penetrate the support plate 3 and the sheet pile 1. Both the support plate 3 and the sheet pile 1 are vertically arranged with strip holes 51 for the bolts 5 to pass through.

[0032] When constructing the steel waler structure, the steel sheet piles 1 are vertically inserted one by one into the bottom of the foundation pit. Then, the support plate 3 is taken out, and the dovetail block 34 on the back side of the support plate 3 is embedded into the groove 11 on the steel sheet pile 1. The support plate 3 is controlled to move the dovetail block 34 into the dovetail groove 12, thus completing the installation of the support plate 3.

[0033] The I-beam waler 2 is then hoisted up, resting against each support plate 3. The waler 2 is then moved downwards, causing the hook plates 31 to hook onto it, thus providing support. Next, the handwheel 42 is controlled to rotate the drive rod 41, controlling the dovetail block 34 to slide vertically. This adjusts the height of the support plates 3 on the sheet pile 1, compensating for construction errors and ensuring that each hook plate 31 is hooked and supports the I-beam waler 2, increasing stability during construction.

[0034] Finally, remove bolt 5 and insert it through the strip hole 51 on the support plate 3 and the sheet pile 1 to complete the locking and fixing between the sheet pile 1 and the I-beam waler 2, thus completing the construction and erection of the steel waler structure. The dismantling process of the steel waler is the reverse and will not be described in detail.

[0035] Therefore, by setting a detachable support plate 3 between the sheet pile 1 and the I-beam waler 2, a stable connection between the two can be achieved using the support plate 3, replacing the traditional welding fixation, improving the convenience of construction, and at the same time enabling the steel waler structure to be freely disassembled and reassembled, facilitating turnover and reuse.

[0036] like Figure 4 As shown, flanges 6 are provided at both ends of the I-beam waler 2, and fasteners 61 are provided between the flanges 6 to achieve quick connection and fixation between two adjacent I-beam walers 2, thereby increasing the stability between the I-beam walers 2.

[0037] like Figure 4 As shown, the I-beam waler 2 includes a pair of vertical plates 21 and a connecting plate 22. The connecting plate 22 is provided in two layers and is arranged horizontally between the pair of vertical plates 21. A reinforcing rib plate 23 located between the pair of vertical plates 21 is provided on the outer side of the connecting plate 22.

[0038] Therefore, by setting up high-strength I-beam walers 2, the structural strength and compressive strength of the I-beam walers 2 are increased, ensuring stability during use.

[0039] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
