Abstract
The utility model relates to a single-row internal supporting structure for a basement. The basement single-row internal supporting structure comprises an angle iron bracket (6), a channel steel back combined member (7), two supporting steel plates (8) and a double channel steel combined member (9), wherein the supporting steel plates (8) are fixed on the upper side and the lower side of the channel steel back combined member (7) respectively; one end of the angle iron bracket (6) is fixed onto a support pile (1) of the basement and the other end of the angle iron bracket (6) is fixed onto the supporting steel plate (8) on the lower side of the channel steel back combined member (7); one end of a connecting combined body of the two supporting steel plates (8) and the channel steel back combined member (7) is fixed onto the support pile (1); the other end of the connecting combined body of the two supporting steel plates (8) and the channel steel back combined member (7) is connected with one end of the double channel steel combined member (9); and the other end of the double channel steel combined member (9) is fixed onto the support pile (1) on the other side of the basement. The single-row internal supporting structure for the basement reduces the supporting construction difficulty of a supporting foundation pit in the basement, enlarges construction space and shortens the construction period.
Description
Technical field
The utility model relate to basement that in deep soft soil basement foundation ditch supporting uses single in support structure, be particularly related to two-layer basement foundation ditch supporting is used in deep soft soil two-layer basement single in support structure, belong to the renovation technique of the single interior support structure of basement.
Background technology
Along with the develop rapidly of China's urban construction, in order to utilize the land development space better, the basement construction has become necessary part, has therefore also produced the foundation pit supporting project technology.In small and medium-sized cities, two-layer basement building is comparatively general at present, when the geology situation is deep soft soil, generally, and in the time of can only adopting interior supporting system as if the limited foundation ditch of ambient conditions, the general pair piling-inner supporting systems that adopt.Double inner supporting body is that ubiquitous problem is respectively that fender post (diaphragm wall) is that two rows support waist rail, and the reserved steel bar difficulty is big; The basement construction space is few; Need twice support replacement, basement construction is long in time limit.
The utility model content
The purpose of this utility model is to consider the problems referred to above and a kind of difficulty of construction that supports pattern foundation pit supporting structure in the basement that reduces is provided, and increases the single interior support structure of construction space and the basement of shortening construction period.The utility model is reasonable in design, and is convenient and practical.
The technical solution of the utility model is: support structure in basement of the present utility model is single, include the angle steel bracket, channel-section steel is to back of the body combined member, supporting steel plate, double flute steel combined member, wherein two supporting steel plates are separately fixed at the up and down both sides of channel-section steel to back of the body combined member, one end of angle steel bracket is fixed on the soldier pile of basement, the other end of angle steel bracket is fixed on the supporting steel plate of channel-section steel to back of the body combined member downside, two supporting steel plates and channel-section steel are fixed on the soldier pile an end of the connection assembly of back of the body combined member, two supporting steel plates and channel-section steel are connected with an end of double flute steel combined member the other end of the connection assembly of back of the body combined member, and the other end of double flute steel combined member is fixed on the soldier pile of basement opposite side.
Above-mentioned angle steel bracket is the angle steel structure.
Above-mentioned channel-section steel includes two blocks of channel-section steels to back of the body combined member, and the back side of two blocks of channel-section steels is fixed by welding in together.
Above-mentioned double flute steel combined member includes two blocks of channel-section steels, and the back side of two blocks of channel-section steels is fixed by welding in together.
The utility model is owing to adopting the local sloping soil-nail wall support+single interior form of structure that supports of putting in stake (wall) top.The utility model considers that mainly when two-layer basement foundation ditch excavates geological conditions be deep soft layer, and there are building or important pipeline in the foundation ditch periphery construction infection scope, during to Excavation Process king-pile top and peripheral sedimentation and the strict restriction of displacement request, this kind design form has reduced the support replacement number of times, increased the space utilization in the basement construction, adopt the steel work support replacement simultaneously, with double support system contrast, at least can save for one to bimestrial construction period, especially suitable to the engineering of construction period strictness.The utility model has solved when propping up supporting system in pattern foundation pit supporting structure adopts, complex procedures, long problem of construction period.The two piling-inner supporting systems of the utility model contrast have operation simple, the advantage that the construction period is short, and the energy accelerating construction progress reduces time cost, produces economic benefit.The utility model is that a kind of design is ingenious, function admirable, support structure in convenient and practical basement is single.
