Background

The history of the arch structure is long, and the arch structure is widely used in bridges, dams, culverts, beams of buildings and the like as early as ancient times, the principle that the compressive bearing capacity of an arch ring is more uniform than that of a straight beam is applied, but the existing arch structure has a larger gap from the objective requirement under certain specific environment conditions with larger external force action.

Disclosure of Invention

The invention provides a connecting rod internal connection type compression-resistant arch structure, which can ensure that the integral internal stress of the arch structure is distributed more uniformly under the action of external force, in order to overcome the defects that the internal and external rings of the arch ring of the existing arch structure are stressed unevenly and are easy to deform and crack under the action of large external force.

The technical scheme adopted by the invention to solve the technical problem is as follows: the connecting rod internal connection type compression-resistant arch structure comprises an arch ring and a connecting rod, wherein the arch ring is an arch ring in any form, two ends of the connecting rod are horizontally connected to an inner ring of the arch ring, the connecting rod and the connecting rod are parallel to each other, in order to prevent the connecting rod from bending and deforming due to gravity, the connecting rod is tied, one end of the tie rod is vertically connected to the inner ring of the arch ring, the other end of the tie rod is connected with the upper part of a transition section ring, the connecting rod is horizontally arranged at the bottom of the ring inner ring and is not connected with the ring, the diameter of the ring inner ring is properly larger than that of the connecting rod, a certain gap is formed between the connecting rod and the upper top surface of the.

Preferably, in the connecting rod internal connection type compression-resistant arch structure, the connecting rods are sequentially and crossly connected to the inner ring of the arch ring, the adjacent connecting rods are in a cross state, and the connecting rods are not connected in a cross state.

Furthermore, in the above connecting rod internal connection type compression-resistant arch structure, the inner ring section (fig. 7 arch ring section AB) between two end points of each connecting rod of the inner ring of the arch ring is connected with two or more groups of connecting rods.

Furthermore, the connecting rod internal connection type compression-resistant arch structure is provided with a protective cover outside the connecting rod.

In the connecting rod internal connection type compression-resistant arch structure, the other parts of the connecting rod except the end points are not fixedly connected with the inner ring of the arch ring, and the internal stress distribution of the connecting rod is not influenced by the external force of the arch ring.

When the two ends of the arch ring move outwards and stress parts are deformed inwards under the action of external force, the connecting rod generates contraction force from the two ends to the middle and balances the outward tension and the inwards deformation of the arch ring by uniform internal stress.

Furthermore, the connecting rod internally-connected compression-resistant arch structure is characterized in that one end of the connecting rod is connected with the inner ring of the arch ring through a fastener. The fastener is composed of two inverted trapezoids, one end of the fastener is provided with a connecting rod hole, the other end of the fastener is connected with the inner ring of the arch ring, the tail end of the connecting rod is provided with a thread and a bolt hole, the connecting rod penetrates through the connecting rod hole of the fastener during installation, the connecting rod is fastened by a nut and is reinforced by the bolt, then the connecting rod, the nut and the bolt are reinforced secondarily by a welding method, and the fastener enables the internal stress of the connecting rod to be more fully utilized.

The invention has the advantages that the connecting rod internal connection type compression-resistant arch structure fully exerts the characteristic of uniform distribution of the internal stress of the connecting rod at the stress part of the arch structure, under the condition of the same overall sectional area (including the sectional area of the connecting rod) and span of the arch structure, the connecting rod internal connection type compression-resistant arch structure has larger compression-resistant bearing capacity which is even more than several times larger than that of the arch structure without the connecting rod, and similarly, under the condition of equal span and external force action, the connecting rod internal connection type compression-resistant arch structure has smaller overall sectional area (including the connecting rod sectional area) corresponding to the arch structure without adopting the connecting rod, namely, the material cost is less, and under the same overall sectional area (including the sectional area of the connecting rod) and external force action condition, the connecting rod internal connection type compression-resistant arch structure has larger span corresponding to the arch structure without the connecting rod.
