Abstract
The patent of the utility model relates to a special multi -functional U shaped steel support in metal mine. This supporting structure mainly includes an upper portion U shaped steel arching, support mounting card cable, support mounting stock, the U shaped steel support leg that connects down, the foot -piece and the spacing angle bar of floorbar of bottom. Wherein V shaped steel is selected for use to U shaped steel the arching on upper portion, can play certain pressure effect that lets, the U shaped steel support leg and the foot -piece of lower part are the mining I -steel of 11#, have the ability of resisting surrouding rock deformation very by force, support mounting bolt installation(3) has further limited the deflection of metal mine tunnel country rock on support mounting card cable. This supporting structure atress is reasonable, and the anti system that combines that lets has the effect of maximizing favourable factors and minimizing unfavourable ones to the stability of maintaining the tunnel, has good engineering application and worth and economic benefits. Be applicable to the roadway support in the metal mine of rock fracture agensis.
Description
Technical field
The utility model relates to the U-shaped steel bracket of a kind of metal mine special-purpose multifunctional, and this structure can be widely used in the supporting of underground construction, is particularly useful for the roadway support of the obsolete metal mine of rock fracture.
Background technology
Along with the development of metal mine industry, Roadway Support Technology obtains the development of advancing by leaps and bounds.Traditional support pattern adopts log hut supporting, progressively developed into the canopy leg capplce supporting that cement is built afterwards, H-shaped steel supporting, concrete spraying support, develop into bolting with wire mesh afterwards again, bolt-spary supports, bolt-mesh-spurting supporting, bolt-mesh-anchor support, U-shaped steel canopy and combined support with bolt-net-cable, although the support pattern in later stage substantially increases the stability of country rock, solve many technical barriers, but in the face of not only pursuing quality now but also pursuing the challenge of speed, need badly and a kind ofly can improve the supporting and protection structure that speed of application can ensure again Drift stability, the support efficiency breaking through traditional supporting effect poor and current is low.
Summary of the invention
This uses novel object to be to provide a kind of metal mine special-purpose multifunctional U-shaped steel bracket, be mainly used in the supporting of underground construction, be particularly useful for the roadway support of the obsolete metal mine of rock fracture, the stability in excavation tunnel can be significantly improved, solve many technical barriers, obtain good Social and economic benef@.
The U-shaped steel bracket of a kind of metal mine special-purpose multifunctional is by foot-piece, the spacing angle bar of bottom girder, U-shaped steel bracket leg, support installing anchor pole, support installing card cable, and U-shaped steel bracket assembles more fishplate bar, U-shaped steel bracket arch, taper liner and nut composition.
As improvement, bottom girder spacing angle bar in two, bottom adopts the 10# length of side to be the equal angle iron of 70mm, is welded on U-shaped steel bracket leg.
As improvement, foot-piece and U-shaped steel bracket leg select 11# mining i beam, improve the stability in metal mine tunnel.
The beneficial effects of the utility model are: the U-shaped steel bracket of this metal mine special-purpose multifunctional is substantially identical with common mine U-shaped steel bracket construction technology, the parameter that support is determined in cross dimensions measurement is carried out to the tunnel of having excavated, mainly comprises the size of top arch and the height of rack leg of support.Then support being installed from down to up, when stamping support installing anchor pole after rack leg installation, carrying out preliminary fixed support with this.When after an arching installation, encircleing leg junction installing card cable and tightening, terminate to this whole installation process.The U-shaped steel bracket arch of its middle and upper part selects V-type steel, can play certain pressure effect that allows; The U-shaped steel bracket leg of bottom and foot-piece are 11# mining i beam, have the ability of resisting very by force surrouding rock deformation; Support installing rockbolt installation, on support installing card cable, further limit the deflection of metal mine roadway surrounding rock.

Reference numeral: (1) foot-piece; (2) the spacing angle bar of bottom girder; (3) U-shaped steel bracket leg; (4) support installing anchor pole; (5) support installing card cable; (6) U-shaped steel bracket assembles more fishplate bar; (7) U-shaped steel bracket arch; (8) taper liner; (9) nut.
Detailed description of the invention
See Fig. 1, Fig. 2, Fig. 3, be described as follows: this Multifunctional U-shaped steel bracket is substantially identical with common U-shaped steel bracket construction technology, first determine that the size of excavated section is convenient to determine further the size of support.Then this support is installed from down to up with reference to Fig. 1 connected mode, need after installation to determine that support fully contacts with roadway surrounding rock section.
The U-shaped steel bracket of a kind of metal mine special-purpose multifunctional is by foot-piece 1, the spacing angle bar 2 of bottom girder, U-shaped steel bracket leg 3, support installing anchor pole 4, support installing card cable 5, and U-shaped steel bracket assembles more fishplate bar 6, and U-shaped steel bracket arch 7, taper liner 8 and nut 9 form.U-shaped steel bracket arch 7 selects V-type steel, utilizes it to allow pressure characteristic discharge burst stress from country rock in time.U-shaped steel bracket leg 3 utilizes its rigidity to bear greatly stress from country rock, and the foot-piece 1 of bottom effectively can prevent pucking, and three part actings in conjunction effectively can improve the stability in metal mine tunnel.
As improvement, bottom girder spacing angle bar in two, bottom adopts the 10# length of side to be the equal angle iron of 70mm, is welded on U-shaped steel bracket leg.
As improvement, foot-piece and U-shaped steel bracket leg select 11# mining i beam, improve the stability in metal mine tunnel.
