Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a prefabricated steel force transmission component used for the gap between a Larsen steel sheet pile and a waist beam. Background Art

[0002] Larsen steel sheet pile is a commonly used support form for foundation pit support structure, which is convenient and quick to construct. Figure 1 and attached Figure 2 The Larsen steel sheet pile 1 adopts a special pile plane, and has bite ears on both sides, through which two adjacent Larsen steel sheet piles can be interlocked and connected into one, so that it has both soil retaining and waterproofing functions. After the foundation pit construction is completed, it can be pulled out and reused.

[0003] Due to the limitation of the plane size of Larsen steel sheet pile and the thickness of steel plate, its rigidity is limited. When used as a retaining member, it is generally used in conjunction with waist beam 2 (the waist beam is generally made of H-shaped steel). Also due to the special-shaped plane of Larsen steel sheet pile 1, special-shaped gap 3 will inevitably appear between waist beam 2 and Larsen steel sheet pile, resulting in one steel sheet pile without direct contact with the waist beam for every other steel sheet pile, and unable to transmit horizontal force. The current design and construction specifications require the force transmission effect of this position to be guaranteed. The common practice is to fill the above-mentioned gaps with cast-in-place concrete. The pouring and curing of concrete requires sufficient time to ensure, which is labor-intensive and time-consuming and affects the construction period. Utility Model Content

[0027] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship between an element or feature shown in the figure and another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or located in other orientations), and the spatial relative description used here can be interpreted accordingly. Moreover, relational terms such as "first" and "second" are only used to distinguish one from another component with the same name, and do not necessarily require or imply that there is any such actual relationship or order between these components.
