Abstract
The utility model relates to a triangular-section beam-circle combination telescopic bracket, belongs to the technical field of coal mine tunnel support equipment, and aims to solve the problems of unstable structure and large converging deformation in a coal mine tunnel support structure. The triangular-section beam-circle combination telescopic bracket consists of a top plate beam-circle combination bracket, two side beam-circle combination brackets and a metal connection clamping cable, wherein the cross sections of the top plate beam-circle combination bracket and the two side beam-circle combination brackets are triangular, and consist of three steel beams and beam-to-beam internally-tangent steel bar circular rings; the top plate beam-circle combination bracket and the two side beam-circle combination brackets are connected into an integral bracket through the metal connection clamping cable. The triangular-section beam-circle combination telescopic bracket has the advantages of simple structure, low consumption of steel, light weight, low cost, convenience in transportation and installation, short working period and high engineering practicability, and the stability of the surrounding rock of roadways can be controlled effectively.
Description
Technical field
The utility model belongs to colliery tunnel support equipment technical field, is specifically related to a kind of colliery tunnel support support, relates in particular to triangular section beam circle combination collapsible timbering.
Background technology
Rich coal resources in China, output is large, and coal seam mode of occurence varies, and mine laneway purposes and production specifications are also different, and therefore, roadway support work is very complicated, and support form is varied.The eighties in 20th century, metallic support develops the principal mode that becomes domestic and international mine roadway support rapidly, and is developed to Yieldable steel support by rigid metal support.For country rock weakness, broken tunnel, metallic support can support rock (coal) body of weak broken well, and the shape and size in tunnel are met the demands, the Yieldable steel support distortion of suitable for surrounding rock body or coal body to a certain extent simultaneously.
Metallic support is generally made with mining i beam or U-shaped steel, the steel consumption of this class support is large, cost is high, weight greatly, very heavy, be not easy to transportation and install, therefore, need a kind of new Yieldable steel support of utility model, effectively to control the stable of roadway surrounding rock.
Summary of the invention
The purpose of this utility model is to provide a kind of triangular section beam circle combination collapsible timbering, and this support not only can effectively solve a stability control difficult problem for coal mine roadway country rock, and support cost is low, easy construction, Technological Economy are feasible.
Technical solution adopted in the utility model is: triangular section beam circle combination collapsible timbering, and it helps beam circle sectional shelf-unit and metal connection clamp cable to form by top board beam circle sectional shelf-unit, two; Described top board beam circle sectional shelf-unit and two helps the cross section of beam circle sectional shelf-unit to be triangle, and by inscribe reinforcing bar annulus composition between three girder steels and beam, top board beam circle sectional shelf-unit and two helps beam circle sectional shelf-unit to connect into integral support by metal connection clamp cable.
Construction using method of the present utility model is: Tunnel Pressure first is on the estimation determined the model of metal connection clamp cable, then help beam circle sectional shelf-unit to couple together top board beam circle sectional shelf-unit and two with metal connection clamp cable, but now fastening metal connection clamp cable not, so that top board beam circle sectional shelf-unit and two helps the section configuration of beam circle sectional shelf-unit to dwindle as far as possible, be convenient to support props in tunnel, after support is propped, help beam circle sectional shelf-unit to strut to roadway surrounding rock top board beam circle sectional shelf-unit and two, make itself and roadway surrounding rock closely connected, when support section configuration meets after designing requirement, fastening metal connection clamp cable, complete the construction of a triangular section beam circle combination collapsible timbering, finally, with longitudinal cylinder lever connecting rod, adjacent triangular section beam circle being combined to collapsible timbering couples together, formation supporting entirety.
Operating principle of the present utility model is: first triangular section beam circle combination collapsible timbering utilizes the strong feature of inscribe reinforcing bar annulus anti-pressure ability between beam after having constructed, and coordinates three reinforcing bar beams, the effect of jointly resisting surrouding rock deformation and tunnel mine pressure; When tunnel, mine pressure constantly increases, and reach gradually after the stressed limit of metal connection clamp cable, top board beam circle sectional shelf-unit and two helps beam circle sectional shelf-unit that relative sliding will occur, thereby the contracting that has realized whole support is moving, avoid the yield failure of support, also guaranteed the stable of roadway surrounding rock simultaneously.
The beneficial effects of the utility model are: triangular section beam circle combination collapsible timbering is simple in structure, steel quantity consumption is few, cost is low, easy construction, the duration is short, engineering practicability is strong, and can adapt to the stress development of roadway surrounding rock, effectively control the stable of roadway surrounding rock.

Marginal data: 1-top board beam circle sectional shelf-unit; 2-two helps beam circle sectional shelf-unit; 3-metal connection clamp cable; 4-girder steel; Inscribe reinforcing bar annulus between 5-beam.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model triangular section beam circle combination collapsible timbering, helps beam circle sectional shelf-unit 2 and metal connection clamp cable 3 to form by top board beam circle sectional shelf-unit 1, two; Described top board beam circle sectional shelf-unit 1 and two helps the cross section of beam circle sectional shelf-unit 2 to be triangle, and form by inscribe reinforcing bar annulus 5 between three girder steels 4 and beam, top board beam circle sectional shelf-unit 1 and two helps beam circle sectional shelf-unit 2 to connect into integral support by metal connection clamp cable 3.
When use, first Tunnel Pressure is on the estimation determined the model of metal connection clamp cable 3, then help beam circle sectional shelf-unit 2 to couple together top board beam circle sectional shelf-unit 1 and two with metal connection clamp cable 3, but now fastening metal connection clamp cable 3 not, so that top board beam circle sectional shelf-unit 1 and two helps the section configuration of beam circle sectional shelf-unit 2 to dwindle as far as possible, be convenient to support props in tunnel, after support is propped, help beam circle sectional shelf-unit 2 to strut to roadway surrounding rock top board beam circle sectional shelf-unit 1 and two, make itself and roadway surrounding rock closely connected, when support section configuration meets after designing requirement, fastening metal connection clamp cable 3, complete the construction of a triangular section beam circle combination collapsible timbering, finally, with longitudinal cylinder lever connecting rod, adjacent triangular section beam circle being combined to collapsible timbering couples together, formation supporting entirety.
