Abstract
A deep foundation pit steel support comprises a supporting hanging plate, wherein the supporting hanging plate is connected with a steel support, the supporting hanging plate is shaped like the letter 'Z' and is anchored on a top beam through expansion bolts. Or the deep foundation pit steel support comprises a steel surrounding purlin, wherein a supporting hanging plate is arranged at one end of the steel surrounding purlin and is connected with a steal support, and the supporting hanging plate is shaped like the letter 'L' and is hung on the steel surrounding purlin through lugs. The deep foundation pit steel support solves the problem of repeated use of the steel supporting hanging plate in the construction of a deep foundation pit, and has the advantages of being simple in structure, being convenient to use, being capable of being reused, saving time and labor and saving cost.
Description
Technical field
The utility model relates to a kind of deep foundation ditch steel to be supported, and relates in particular to a kind of deep foundation ditch steel that is applicable to the subway station and supports.
Background technology
Deep foundation pit support system is generally reinforced concrete support and steel supports two kinds, and it is convenient that steel supports because of installing and removing, and uses comparatively extensive.Steel for the Guan Liang position supports, for the stress diffusion, and pre-embedded steel slab in concrete, the steel that encloses the purlin position for steel supports, and encloses welding steel on the purlin at steel.No matter pre-embedded steel slab is still enclosing welding steel on the purlin, all is disposable, and waste of material is larger.
The utility model content
Its purpose of the utility model just is to provide a kind of deep foundation ditch steel to support, and has solved the recycling problem of steel support link plate in the deep foundation pit construction.Have characteristics simple in structure, easy to use, and can reuse, time saving and energy saving, save cost.
The technical scheme that realizes above-mentioned purpose and take comprises the support link plate, supports to connect the steel support on the link plate, and described support link plate is " Z " shape, supports the link plate upper end and is provided with hanger and bolt hole, and bolt hole connects expansion bolt and is anchored on the Guan Liang.
Comprise that steel encloses purlin, steel encloses purlin one end and is provided with the support link plate, supports to connect the steel support on the link plate, and described support link plate is " L " shape, supports the link plate upper end and is provided with hole for hoist, supports the link plate back side and is provided with hangers, and described support link plate hangs over steel through hangers and encloses on the purlin.
Compared with prior art the utlity model has following advantage.
The utility model has adopted on Guan Liang or has enclosed purlin at steel the structure design that supports link plate has been set, and becomes pre-embedded steel slab or welding steel and connects into bolt, thereby solved the recycling problem of steel support link plate in the deep foundation pit construction.Have characteristics simple in structure, easy to use, and can reuse, time saving and energy saving, save cost.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 supports the cladding panel structure schematic diagram for this device embodiment one.
Fig. 2 supports the cladding panel structure schematic diagram for this device embodiment two.
The specific embodiment
Comprise and support link plate 1, support connection steel support on the link plate 1, as shown in Figure 1, described support link plate 1 is " Z " shape, supports link plate 1 upper end and is provided with hanger 2 and bolt hole 3, and bolt hole 3 connects expansion bolt and is anchored on the Guan Liang.
Described bolt hole 3 is provided with 1-3.
Comprise that steel encloses purlin, steel encloses purlin one end and is provided with support link plate 1, supports to connect the steel support on the link plate 1, as shown in Figure 2, described support link plate 1 is " L " shape, supports link plate 1 upper end and is provided with hole for hoist 4, support link plate 1 back side and be provided with hangers 5, described support link plate 1 hangs over steel through hangers 5 and encloses on the purlin.
Described hangers 5 is provided with 1-3.
The steel plate that (1) will be embedded in the concrete changes to the support plate-hanging type, and supporting link plate is the steel plate of 16mm thickness, and upper surface is anchored on the Guan Liang by expansion bolt, and behind the steel supporting removal, link plate can be won recycling.
(2) will be welded on steel and enclose steel plate on the purlin and change to and support the link plate form, and behind the steel supporting removal, support link plate and can win recycling.
Embodiment
1, project profile
Take No. 4 lines of certain subway as example, introduce in detail and support the link plate use procedure.No. 4 line stations of this subway total length 168.8m, underground two layers of an island platform.Station agent structure excavation of foundation pit degree of depth 17.8m～18.1m, standard paragraphs width 20.5m, bellend width 24.4m designs altogether upper, middle and lower 3 road steel and supports.
Construction period in order to save cost, changes to plate-hanging type with the steel plate that is embedded on the Guan Liang, develops into again afterwards the welding steel that steel is enclosed on the purlin and changes to plate-hanging type.Through after the practical application, the sensation link plate has great role aspect construction cost, the construction speed.
2, implementation result
(1) supports link plate in the application that steel supports, as long as antirust work is carried out, can reuse tens times.This station length 168.8m uses 306 link plates altogether, average every plate 60kg, 306 * 60=18360kg, effectively reduce project cost.
(2) the support link plate adopts factory process, only need install during use to get final product, and compares with pre-embedded steel slab, and speed of application is fast.
Claims (4)
1. a deep foundation ditch steel supports, comprise and support link plate (1), supporting the upper steel that connects of link plate (1) supports, it is characterized in that, described support link plate (1) is " Z " shape, support link plate (1) upper end and be provided with hanger (2) and bolt hole (3), bolt hole (3) connects expansion bolt and is anchored on the Guan Liang.
2. a kind of deep foundation ditch steel according to claim 1 supports, and it is characterized in that, described bolt hole (3) is provided with 1-3.
3. a deep foundation ditch steel supports, comprise that steel encloses purlin, steel encloses purlin one end and is provided with support link plate (1), supporting the upper steel that connects of link plate (1) supports, it is characterized in that described support link plate (1) is " L " shape, support link plate (1) upper end and be provided with hole for hoist (4), support link plate (1) back side and be provided with hangers (5), described support link plate (1) hangs over steel through hangers (5) and encloses on the purlin.
