Described transverse strut comprises longitudinally spaced crossbeam successively.
Between the top of every group of temporary steel tubing string, be equipped with temporary concrete longeron, between two temporary concrete longerons, be provided with temporary concrete crossbeam.
Described longitudinal and cross beam is i iron.
Metro Deep Excavation concrete support described in the utility model hangs mould mould, there is construction simple, with low cost, supporting structure is firm, save the beneficial effect of engineering time, and can effectively solve the problem that the deep foundation ditch scope of operation is narrow and small, excavation of foundation pit conflicts with concrete Construction of Supporting, guarantee that deep foundation ditch and concrete support synchronous construction, have improved foundation pit construction effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A place enlarged drawing in Fig. 1;
Fig. 3 is that B in Fig. 1 is to view;
Fig. 4 is the structural representation of longitude strut.
The specific embodiment
By the Metro Deep Excavation concrete support shown in Fig. 1-Fig. 4, hang mould mould, comprise two groups of temporary steel tubing string groups that lateral separation is oppositely arranged, every group of temporary steel tubing string group includes two vertical temporary steel tubing strings 8 and the longitude strut 5 that the vertical equity being installed between described two temporary steel tubing string 8 middle parts extends that longitudinal separation is oppositely arranged.Temporary steel tubing string 8 has four, and four temporary steel tubing strings 8 lay respectively at four corner points of rectangle, and four temporary steel tubing strings 8 are for be arrangeding in parallel between two, and the bottom of four temporary steel tubing strings 8 is all inserted in the subway foundation pit 10 hole subsoil cubic meters of stone.
Described longitudinal linking beam comprises the batten plate 16 being fixedly connected by welding between two longerons 15 of spaced and parallel setting and two longerons 15, on each temporary steel tubing string 8, be all installed with steel corbel 13, the end of longitude strut 5 is fixedly connected with the steel corbel 13 on corresponding temporary steel tubing string 8, and the steel corbel 13 on a temporary steel tubing string 8 is welded to connect in longitude strut 5 one end and temporary steel tubing string group, the other end is welded to connect with the steel corbel 13 on interior another temporary steel tubing string 8 of temporary steel tubing string group.
Two groups of temporary steel tubing string groups have two longitude struts 5, between two longitude struts 5, be fixedly connected with transverse strut 6, transverse strut 6 is positioned at the upside of two longitude struts 5, described transverse strut 6 comprises longitudinally several crossbeams 14 that spaced and parallel arranges successively, crossbeam 14 extends for transverse horizontal, and crossbeam 14 one end are welded on a longitude strut 5, the other end is welded on another root longitude strut 5.14 3, crossbeam is one group and between three crossbeams 14, by organizing batten plate separately, is fixedly connected with on the same group.Described longeron 15 and crossbeam 14 are Two bors d's oeuveres 20a i iron.
Transverse strut 6 upsides are equipped with the horizontally extending lumps of wood 11, the lumps of wood 11 arranges several, and several lumps of wood 11 are that the every lumps of wood 11 is longitudinal extension along laterally spaced and parallel setting successively, the upside of the lumps of wood 11 is equipped with veneer 12, and this veneer 12 is the thick template of 15mm.
Between every temporary steel tubing string 8 and transverse strut 6, be equipped with the bearing diagonal 7 that is positioned at transverse strut 6 downsides, bearing diagonal 7 is Two bors d's oeuveres 20a i iron, bearing diagonal 7 tops and transverse strut 6 welding, bottom and 8 welding of temporary steel tubing string, between every temporary steel tubing string 8 and transverse strut 6, be equipped with the lacing wire 4 that is positioned at transverse strut 6 upsides, lacing wire 4 is plain bar, lacing wire 4 bottoms and transverse strut 6 middle part welding, top and 8 welding of temporary steel tubing string.
The temporary concrete longeron 2 that the vertical equity that is all fixedly connected by welding between two temporary steel tubing string 8 tops in every group of temporary steel tubing string group extends, two groups of temporary steel tubing string groups have two temporary concrete longerons 2, the temporary concrete crossbeam 3 that has been fixedly connected by welding between two temporary concrete longerons 2, temporary concrete crossbeam 3 is that transverse horizontal is extended.
Metro Deep Excavation concrete support described in the utility model hangs mould mould, in practice of construction, outside the both sides of subway foundation pit 10, be equipped with hand excavated pile 9, in the cubic metre of earth and stone of the equal transplanting of hand excavated pile 9 outside subway foundation pit 10 both sides, between hand excavated pile 9 and contiguous temporary concrete longeron 2, be fixedly connected with intermediate transverse girder 1, to play the effect of reinforcing, and concrete also can be set between hand excavated pile 9 and adjacent temporary steel tubing string group support.
Metro Deep Excavation concrete support described in the utility model hangs mould mould, described longitude strut 5, transverse strut 6 and bearing diagonal 7 form bed die bracket component, transverse strut 6 on longitude strut 5 is wherein also that concrete support shaped steel master is stupefied, transverse strut 6 and longitude strut 5 support load stress system as concrete, and by steel corbel 13, concrete support, bed die bracket component and template load are delivered on column; Lacing wire 4 is equivalent to hang membrane module, and lacing wire 4, except the auxiliary primary structure member as load, also guarantees the camber of concrete support, prevents that bed die deformation of timbering from affecting the camber of concrete support.Described veneer 12 is bed die template, carries out the colligation of concrete bearing bar after all templates install, and side form is installed, and carries out concrete and builds.Because concrete supports span, can be greater than 8m, therefore, Metro Deep Excavation concrete support hangs mould mould need wait for that concrete support strength reaches 100% design strength and could remove.In this period, below lid shoveling rock excavation and transportation all can be supported by concrete, do not affect and cover digging structure construction.
