Abstract
The utility model relates to a steel support device of adding prepress, which is used for an enclosing body of a foundation pit of construction work. A jack is fixed at the outer side of a sheathing body box formed from two steel boxes which are mutually combined, wherein, both ends of the jack are respectively fixed on the two steel boxes. Rectangular wedge holes are correspondingly arranged on the upper and the lower surfaces of the two sheathed steel boxes, and steel wedge pins are inserted in the holes. The utility model can be adjusted according to needs at any moment and achieves the design requirements of controlling the stress and the displacement of the enclosing body of a foundation pit, and simultaneously the stress of the straight end and the inclined support end of the steel support conforms to a design calculated value. Nodes can have the advantages of safety, reliability, convenient adjustment and repeated use under a stress state of a large tonnage.
Description
The utility model is that a kind of steel of being applied to bracing of foundation pit body in the construction work supports and is added with prestressing apparatus.
In building in the modern times,, do the bracing of foundation pit body and support in order not influence the building around the engineering and the protection of pipeline.Existing steel supports prestressed structure, adopts the steel supporting base end portion to add prestressing force with jack, returns in the space that forms between the purlin at steel supporting base end portion and steel, insert steel plate washer, then steel plate washer is welded to form stressed node, welds bearing diagonal shaped steel again, support the supporting force request to reach.This steel supports the shortcoming that adds prestressed structure, and the prestressing node need weld immediately, can't repeat repeatedly the prestressing force that applies to be adjusted, and does not reach the requirement of bracing of foundation pit height precision control displacement; The stressed stressed apportioning cost of design-calculated that do not reach of steel support end and steel diagonal brace end is arranged again, cause the fender body displacement of the local place of steel diagonal brace, distortion, influence the protection of engineering surrounding buildings and pipeline.
The purpose of this utility model is to overcome above-mentioned steel to support the shortcoming that adds prestressed structure, provides a kind of steel that solves to support and repeatedly be added with prestressed device, makes it reach the requirement of high accuracy control bracing of foundation pit displacement body.
The purpose of this utility model is to realize like this.Steel supports and is added with prestressing apparatus, forms the fit casing by the 2 mutual sockets of two steel casees, is fixed with jack 3 in the outside of fit casing.The two ends of jack are separately fixed on two steel casees, and the corresponding rectangle that has is carved the hole on two steel case upper and lower faces behind the fit, is inserted with steel in the hole and carves pin 1, make the fixing and power transmission usefulness of fit casing.Regulate steel and carve the insertion depth of pin, can change the two ends lateral length of fit casing.During use, stressed steel pipe 4 is fixed in respectively on two steel casees, makes the total length of steel pipe change the total length of steel pipe with the length of regulating sleeve mould assembling body under stressed state.When the elongation of the hydraulic jack of fit casing side, support the internal stress increase and reach and to insert steel after the designing requirement and carve pin and fix.
This device can have two hydraulic jacks, is separately fixed at the both sides of fit casing, and the two ends of each jack are separately fixed on two steel casees.After the prestressing, hydraulic jack can be pulled down.
The device that the utility model is used as the steel support system of deep foundation pit construction, owing to can regulate at any time as required, reached the stressed and displacement designing requirement of control bracing of foundation pit body, guaranteed that the deep foundation ditch surrounding buildings thing of constructing and pipeline displacement and sedimentation are effectively controlled; Particularly solved the difficult problem of high accuracy control sedimentation and displacement in the peripheral deep foundation construction of constructing metro tunnel and protection building; Steel supports straight end and the stressed design calculated value that meets of bearing diagonal end simultaneously, and node can have advantage safe, reliable, easy to adjust when the large-tonnage stress, and can repeatedly regulate as required, also can be repeatedly used in Other Engineering.This device solves unsolved always problem in the realm of building construction, prove a kind of desirable steel in the practice and support and be added with prestressing apparatus, have good economic benefit and great social benefit.
The utility model by following examples extremely accompanying drawing provide.
1, steel is carved pin, 2 steel casees, 3 jack, 4 steel pipes.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model fundamental diagrams.
Accompanying drawing 3 is steel supporting section point diagrams.
Embodiment:
Steel supports and is added with prestressing apparatus, form the fit casing by the 2 mutual sockets of two steel casees, be fixed with two jack 3 in the both sides of fit casing, the two ends of jack are separately fixed on two steel casees, the corresponding rectangle that has is carved the hole on two steel case upper and lower faces behind the fit, is inserted with steel in the hole and carves pin 1.
Claims (2)
1, a kind of steel supports and is added with prestressing apparatus, it is characterized in that having two steel casees (2) socket composition fit casing mutually, is fixed with jack (3) in the outside of fit casing, and the two ends of jack are separately fixed on two steel casees; The corresponding rectangle that has is carved the hole on two steel case upper and lower faces behind the fit, is inserted with steel in the hole and carves pin (1).
2, be added with prestressing apparatus according to the described steel support of claim 1, it is characterized in that having two jack, be separately fixed at the both sides of fit casing, the two ends of each jack are separately fixed on two steel casees.
