Abstract
The utility model relates to a steel trestle structure used on cliff terrains. The steel trestle structure has the advantages of reliable structure, convenience in construction, mature technology, low cost and short construction period. The structure is provided with a bedrock surface of a cliff and is characterized in that inverted triangle structures are arranged along the line of a trestle built according to the plan at intervals and are formed by steel beams, steel braces and the bedrock surface; the connection ends of the steel beams and the bedrock surface and the connection ends of the steel braces and the bedrock surface are respectively fixed by connection section steel and anchor rods anchored in the bedrock surface corresponding to the connection section steel; and a plurality of small longitudinal beams are welded on the steel beams along the longitudinal direction of the trestle. The structure is suitable for constructing pedestrian or simple roads in the cliff terrain environment in the mountain areas and is a light structure suitable to be built under the condition of cliff terrains.
Description
Technical field
The utility model relates to a kind of steel trestle structure that is used for the cliff landform.Being applicable in the bridge engineering of mountain area, being specially adapted in the cliff terrain environment of mountain area to build People's Bank of China or low-cost road engineering, is a kind of lightweight section trestle structure of under the cliff orographic condition, building of being suitable for.
Background technology
In western mountainous areas or scenic spot, cliff is arranged more, People's Bank of China or low-cost road are built relatively difficulty.In the prior art, build the following three kinds of forms of the general employing of People's Bank of China or low-cost road on the cliff: tunnel type, half hole formula and bridge type.
Tunnel type promptly adopts full bore tunnel form, and job practices confirms that according to geological condition, country rock rank and buried depth situation full section method, benching tunnelling method, CD method, CRD method etc. are generally arranged, and the construction working amount is big, and cost is higher relatively, and the construction period is longer.
Half hole formula is that section is hazy form, and with respect to tunnel type, the construction working amount is less relatively; Construction costs is relatively low, and the construction period is shorter relatively, but for general sidewalk; Be the control cost; Reduce the support engineering amount, generally only under geological conditions and country rock rank good conditions, use, job practices generally adopts benching tunnelling method.
The bridge form can adopt different forms according to landform, if route spacing ground under cliff is lower, can adopt general conventional beam bridge, and substructure can adopt column, and the basis can be adopted pile foundation according to different geological conditionss, enlarged basis etc.; If ground is higher under the relative cliff of bridge, then substructure is provided with difficulty, engineering quantity is huge, and is even unfeasible, and be employed in the cliff side more the bridge form that horizontal outrigger is done the basis is set this moment.All there is shortcomings such as receiving the influence of topography is big, constructional difficulties, cost is high, the cycle is long in above variety of way.
Summary of the invention
The technical problem that the utility model will solve is: to the problem of above-mentioned existence, a kind of reliable in structure, easy construction, technology maturation, cost is low, the duration the is short steel trestle structure that is used for the cliff landform are provided.
The technical scheme that the utility model adopted is: the steel trestle structure that is used for the cliff landform; Bedrock surface with cliff; It is characterized in that: the del structure is set along intending the compartment of terrain along the line of building trestle; Said del structure is surrounded by gooseneck, steel diagonal brace and bedrock surface, and the link of gooseneck and steel diagonal brace and bedrock surface is fixed through being connected the anchor pole that shaped steel and correspondence position be anchored in the bedrock surface respectively, and said gooseneck upper edge trestle is some stringers of welding vertically.
Said connection shaped steel is that bedrock surface is close in H shaped steel and its inboard.
The two side horizontal positioned of said H shaped steel, said anchor pole are fixedly welded on and go up the knuckle place in the H shaped steel groove.
Said gooseneck is a square tube, be arranged on the H shaped steel and its center of gravity through the below anchor pole.
Said stringer adopts angle steel.
Said gooseneck top is provided with checkered plates and simple and easy railing.
The beneficial effect of the utility model is: the utility model adopts the anchor structure of anchor pole as trestle, brings into play that its tension, shear resistance are strong, the characteristics of easy construction, technology maturation.The utility model is stressed clearly, exploitativeness is strong, on cliff, building People's Bank of China or low-cost road a kind of new form of structure is provided.With respect to present existing technology; Have that compliance is strong, reliable in structure, easy construction, technology maturation, cost is low, the duration is short advantage; Be specially adapted to the built environment that orographic condition is abominable, large-scale construction equipment can't be marched into the arena, the construction plant is restricted, the material that is adopted, member are also conventional.

The specific embodiment
Like Fig. 1 ~ shown in Figure 3; Present embodiment is a kind of steel trestle structure that is used for the cliff landform; It mainly comprises gooseneck 5, steel diagonal brace 3, connects shaped steel 2 and anchor pole 1, and wherein 1 fen two rows of anchor pole are arranged on the bedrock surface 8 of cliff, and an end of upper and lower anchor pole is anchored in the bedrock surface 8, outside the other end exposure bedrock surface 8; The exposure part is welded with being connected shaped steel 2, and anchor pole 1 need reach design anchored force and necessary security deposit.Gooseneck 5 one ends weld with the shaped steel 2 that is connected of last anchor pole side, an end and the welding of steel diagonal brace 3 upper ends, and weld with the shaped steel 2 that is connected of following anchor pole side steel diagonal brace 3 lower ends, forms stable triangular structure.Said gooseneck 5 tops are covered with checkered plates 6 and fixing with gooseneck 5 welding, and gooseneck 5 outsides are provided with simple and easy railing 7.For increasing the longitudinal stability of this structure, vertical at gooseneck 5 upper edge trestles, weld several stringers 4, simultaneously checkered plates 6 and simple and easy railing 7 are played the supplemental support effect.Stringer described in the present embodiment 4 adopts angle steel.
As shown in Figure 4, said connection shaped steel 2 adopts H shaped steel.H shaped steel two side is horizontal arrangement in the present embodiment, and said anchor pole is fixedly welded on and goes up the knuckle place in the H shaped steel groove.Said gooseneck 5 is a square tube, be arranged on the H shaped steel and its center of gravity line pass the below anchor pole 1.When connection shaped steel 2 is provided with, require end and bedrock surface 8 to be close to.Connect shaped steel 2 and not only play the effect that connects anchor pole 1 and gooseneck 5 or steel diagonal brace 3, and participation is stressed jointly with anchor pole 1, it is excessive to prevent effectively that anchor pole 1 is out of shape.
