Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically to a cross-braced frame bridge. Background Art

[0002] At present, with the vigorous development of municipal road reconstruction in my country, the intersection of new roads with existing roads and channels is inevitable, and the application of large skew angle frame bridges is becoming more and more widespread.

[0003] In the construction of urban traffic network, municipal bridges with large skew angles often appear, and urban bridges with skew angles exceeding 45 degrees are sometimes unavoidable. As we all know, such large skew angle bridges have obvious structural spatial effects, especially for urban bridges with relatively large spans. However, such large-angle skew beam bridge schemes will cause beam body dislocation, bearing displacement, and main beam cracks. Moreover, for urban construction areas with dense pipelines, there is no condition for the installation of composite foundation piles, and large-area slab foundations cannot be used.

[0004] Therefore, how to avoid pipelines in the construction area and reduce beam defects has become the key to the design of large-angle skew bridges. Utility Model Content

[0005] The utility model provides a cross-braced frame bridge to solve the existing problems of prolonged construction period and high cost caused by driving anti-movement piles and difficulty in construction when the pipe network under the bridge is dense.

[0006] According to one aspect of the utility model, a cross-braced frame bridge is provided, comprising supporting units, the supporting units are arranged in parallel and spaced apart, the supporting units comprise foundation piles, pile top tie beams and a top plate, the foundation piles are arranged in parallel and spaced apart along the length direction of the bridge; the pile top tie beams are arranged on the tops of adjacent foundation piles, and the top plate is erected on the pile top tie beams through side walls; support beams are arranged between the tie beams of adjacent supporting units, the support beams are arranged in parallel and spaced apart, and the angle between the support beams and the tie beams is acute.

[0007] Preferably, based on the above solution, a cable-stayed beam is provided between adjacent support beams, and the length of the cable-stayed beam is equal to the length of the support beam.

[0008] Preferably, based on the above scheme, there are three support units, and the support beams on both sides of the tie beam of the middle support unit are in a straight line structure to form a wiring channel.

[0009] The utility model discloses a cross-braced frame bridge, which forms a frame structure by arranging a plurality of support beams arranged at intervals between the pile top tie beams, and utilizing the support beams and the pile top tie beams to resist the backfill pressure of the abutment. Compared with a straight-line abutment with double-row piles, the utility model has a more stable structure, is easier to construct, and is more convenient for the road line position and channel direction.

[0016] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] It should be understood that when used in this specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections.

[0018] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0019] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0020] In the embodiments shown in the drawings, the directions (such as up, down, left, right, front and back) used to explain the structure and movement of the various components of the present invention are not absolute but relative. These descriptions are appropriate when the components are in the positions shown in the drawings. If the description of the positions of the components changes, the directions also change accordingly.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0023] See also Figure 1 , and combined with Figure 2 and Figure 3 As shown, a cross-braced frame bridge of the utility model comprises supporting units 1, wherein the supporting units 1 are arranged in parallel and spaced apart along the width direction of the bridge, and specifically the supporting units 1 comprise foundation piles 2, pile top tie beams 3 and top plates 4, wherein the foundation piles 2 are arranged in parallel and spaced apart along the length direction of the bridge; the pile top tie beams 3 are arranged on the tops of adjacent foundation piles 2, and the top plates 4 are erected on the pile top tie beams 3 through side walls 5; supporting beams 6 are arranged between the pile top tie beams 3 of adjacent supporting units 1, and the supporting beams 6 are arranged in parallel and spaced apart, and the angle between the supporting beams 6 and the pile top tie beams 3 is acute.

[0024] That is to say, under the action of the pile top tie beam 3, the foundation piles 2 of the same supporting unit 1 are connected to form an integrated structure, and then the adjacent supporting units 1 are connected to form an integrated structure through the action between the support beam 6 and the pile top tie beam 3 to ensure its stability. At the same time, since the pile top tie beam 3 and the support beam 6 are set at an acute angle, when a pipeline needs to pass through the bridge body, the relative positions of the support beams 6 on the adjacent sides can be designed to achieve reasonable avoidance, making its construction simpler.

[0025] In order to further achieve the stability of its structure, the utility model also arranges a cable-stayed beam 7 between adjacent support beams 6. The length of the cable-stayed beam 7 is equal to the length of the support beam 6, so that the cable-stayed beam 7 divides the space formed between the adjacent support beams 6 and the pile top tie beam 3 into two structures with equal cross-sections to achieve uniform force.

[0026] The utility model has three supporting units 1, and the supporting beams 6 on both sides of the tie beam of the middle supporting unit 1 are in a straight line structure to form a wiring channel to facilitate the direction of the pipeline or pipeline.

[0027] The utility model is a cross-braced frame bridge, which is provided with a plurality of support beams 6 arranged at intervals between the pile top tie beams 3, and a frame structure is formed by the support beams 6 and the pile top tie beams 3 to resist the backfill pressure of the abutment. Compared with a straight-line abutment with double-row piles, the utility model has a more stable structure, is easier to construct, and is more convenient for the road line position and channel direction.

[0028] Finally, the method of this application is only a preferred implementation scheme and is not intended to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
