The bottom of the two sides of the bridge deck is respectively provided with a steel plate for transversely clamping the longitudinal beam, the steel plates are fixed with the bridge deck through bolts, and the bolts are arranged on the two sides of the longitudinal beam.

Foretell view landing stage still includes railing and breast board, the railing erects in the both ends of decking, and the breast board is connected with adjacent railing along vertical.

The bottom of the pile cap is provided with a column groove for accommodating the support column.

The support column, the pile cap, the longitudinal beam, the cross beam and the bridge deck are made of concrete.

The pillars, pile caps, longitudinal beams, cross beams and bridge decks are prefabricated members.

The invention has the advantages that:

the landscape trestle with the full prefabricated structure is locked and connected with the longitudinal beam and the cross beam in a tenon-and-mortise structure through the cross-shaped through groove at the pile cap, the bridge deck is sequentially paved by adopting transversely fixed bridge deck plates, and meanwhile, the paved bridge deck plays a role of fixing the tenon-and-mortise structure at the top of the pile cap.

The invention has simple structure and convenient construction, all components are prefabricated parts, the structure is integrally stable and reliable, the component quality is uniform and controllable, and the firmness of the mortise and tenon structure and the integrity of the bridge body can be enhanced by adjusting the angle theta to be an acute angle according to the geology and the bridge type on site; the landscape trestle effectively solves the problems that the existing landscape trestle is long in construction period, wasting of resources, destroying of ecological environment and the like, saves a large amount of manpower and material resources, improves construction efficiency, shortens construction period, and has strong practicability and wide applicability.

The designations in the drawings have the following meanings: 1. pillar, 2, pile cap, 3, longitudinal beam, 4, crossbeam, 5, decking, 6, bolt, 7, steel sheet, 8, railing.

Detailed Description

The invention is described in detail below with reference to the figures and the embodiments.

A landscape trestle comprises a pillar 1, pile caps 2, longitudinal beams 3, cross beams 4 and bridge decks 5.

According to the design size of the trestle, a concrete pillar 1, a concrete pile cap 2, a concrete longitudinal beam 3, a concrete cross beam 4 and a concrete bridge deck 5 are prefabricated.

A pair of transversely arranged struts 1 are used as a group, and a plurality of groups of longitudinally arranged struts 1 form a bridge pile;

through the post groove of bottom, concrete pile cap 2 is fixed at the top of concrete support 1, and the upper end of concrete pile cap 2 is equipped with "ten" style of calligraphy and leads to the groove for hold concrete longeron 3 and concrete beam 4.

Two ends of the concrete longitudinal beam 3 are clamped and fixed in the crossed through grooves of the adjacent pile caps 2 and are longitudinally arranged, end angles are respectively arranged at the two ends, the angle theta is a right angle or an acute angle, and the right angle can be selected for a small bridge or a bridge with smaller span; for trestles with large span or long support columns 1, in order to avoid the swing amplitude of the support columns 1 due to geological reasons, the concrete longitudinal beams 3 are moved out of the concrete pile caps 2 along the longitudinal direction, and the angle theta can be an acute angle.

Two ends of the concrete beam 4 are clamped and fixed in the cross-shaped through grooves of the adjacent pile caps 2 and are arranged along the transverse direction; and the notches arranged at the two ends of the cross beam 4 are matched with the end angles of the longitudinal beam 3 and are reversely buckled on the end angles to form a tenon-and-mortise structure for locking the longitudinal beam 3. Namely, the concrete longitudinal beams 3 on the two sides of the concrete pile cap 2 are abutted in the cross-shaped through groove, and the top of the concrete longitudinal beams is pressed by the concrete cross beam 4.

The bridge deck plate 5 is laid between the longitudinal beams 3 along the transverse direction, the bottom parts of the two sides of the bridge deck plate 5 are respectively provided with a steel plate 7 for clamping the longitudinal beams 3 along the transverse direction, the steel plate 7 is fixed with the bridge deck plate 5 through bolts 6, and the bolts 6 are arranged on the two sides of the longitudinal beams 3. And a plurality of bridge decks 5 are sequentially paved in the longitudinal direction to form a bridge floor.

A plurality of railing 8 erect respectively in the both sides of bridge floor, and the breast board is located between adjacent railing 8 along vertically.

After the assembly is completed, grouting treatment can be adopted for reinforcing the structural nodes and joints.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
