Technical Field

The invention belongs to the field of road and bridge structures, and particularly relates to a fish-belly sill for a totally enclosed sound barrier.

Background

Along with the requirement for environmental protection is higher and higher, closed sound barrier structure is adopted in more district, and its self load is big, and when the train passes through at a high speed, aerodynamic load is also bigger, and general simple beam section is difficult to satisfy the structural stress requirement, and structures such as local ribbing are under construction the degree of difficulty big, and the view effect is poor. There is therefore a need for a new bridge construction to meet the need for installing a totally enclosed sound barrier construction.

Disclosure of Invention

The invention is provided for solving the problems in the prior art, and aims to provide a fish-belly sill for a totally enclosed sound barrier.

The technical scheme of the invention is as follows: the utility model provides a fish belly sill for totally enclosed sound barrier, includes the roof beam body, the roof beam body is including the roof plate that is located the upper end, the bottom plate that is located the lower extreme, roof plate, bottom plate pass through the edge web of both sides and link to each other, form the reservation basis that is used for installing enclosed sound barrier on the roof plate.

An upper groove for assembly is formed in the top of the reserved foundation, and a connecting flange is pre-embedded in the side wall of the reserved foundation.

The connecting anchor bolts penetrate through the connecting flanges to fix the closed sound barrier installed in the upper groove.

The top plate, the bottom plate and the side web plate are enclosed to form a box chamber structure.

And a middle web plate is further arranged between the top plate and the bottom plate, and the top plate, the bottom plate, the side web plates and the middle web plate are enclosed to form a multi-chamber structure.

The side web plates are linear or arc-shaped.

The arc line is an outward convex arc line.

The reserved foundation is higher than the top plate.

According to the invention, the sound barrier foundation preset at the top is poured together with the reserved foundation of the beam body, so that the connection reliability with the beam body is ensured, the closed sound barrier load can be transmitted through the side web plate, the stress is clear, the side web plate adopts the inclined web plate to reduce the transverse length of the bottom plate, the structural size of the lower part is reduced, the outer contour is simple, and the template is convenient to manufacture; the beam body is made of concrete materials, so that the durability is high, the later-stage maintenance workload is small, and the application is wide.

Detailed Description

The present invention is described in detail below with reference to the accompanying drawings and examples:

as shown in fig. 1 to 3, the fish-belly sill for the totally enclosed sound barrier comprises a sill body, wherein the sill body comprises a top plate 1 located at the upper end and a bottom plate 2 located at the lower end, the top plate 1 and the bottom plate 2 are connected through side webs 3 at two sides, and a reserved foundation 5 for installing an enclosed sound barrier 7 is formed on the top plate 1.

An upper groove for assembly is formed in the top of the reserved foundation 5, and a connecting flange is embedded in the side wall of the reserved foundation 5.

The connecting anchor 6 passes through the connecting flange and fixes the closed sound barrier 7 installed in the upper groove.

The top plate 1, the bottom plate 2 and the side web plate 3 enclose to form a box chamber structure.

And a middle web plate 4 is further arranged between the top plate 1 and the bottom plate 2, and the top plate 1, the bottom plate 2, the side web plates 3 and the middle web plate 4 are enclosed to form a multi-chamber structure.

The side web 3 is linear or arc.

The arc line is an outward convex arc line.

The reserved foundation 5 is higher than the top plate 1.

The reserved foundation 5 is used for embedding a connecting piece in advance, and the closed sound barrier 7 is connected with the beam body.

The side webs 3 adopt oblique webs to reduce the transverse length of the bottom plate, thereby reducing the size of the substructure.

Considering the reaction force of an upper support on the top plate 1 and the transmission of the load of an upper contact net, a middle web plate 4 is generally adopted to divide the chamber into three chambers; when the width of the bridge deck is small, the middle web can be omitted to form a single-box single-chamber structure.

The reserved foundation 5 can be longitudinally arranged in the full length mode or only arranged at the position of the anchoring closed type sound barrier; the reserved foundation 5 protrudes out of the bridge floor to support the sidewalk cover plate and is used as a part of the cable trough.

The closed sound barrier 7 is connected through a connecting flange pre-embedded in the reserved foundation 5.
