Description

Technical Field

[0001] The utility model relates to the technical field of bridge installation, and particularly relates to a finished bridge embedded channel box. Background Art

[0002] Generally speaking, in building construction projects, rectangular holes need to be preset on the floor slab structure in advance to install vertical bridges. In order to ensure that the verticality of the vertical bridge meets the acceptance requirements, the length and width of the preset rectangular holes are usually 5-10 cm larger than the bridge to facilitate sufficient adjustment margin and installation space for the bridge cover plate during subsequent bridge construction. In addition, the gap between the bridge and the preset hole needs to be filled tightly with fireproof materials such as fireproof mud that meet the requirements of design specifications. However, due to reasons such as poor viscosity of the fireproof materials, the fireproof materials filled in the lower part of the preset hole are very easy to be damaged during cross-construction with other professions, and fall off naturally due to environmental vibration or self-weight, affecting the fireproof effect. The utility model with the publication number CN201818904U records a connecting bridge, including a bridge and a connecting plate installed on the bridge, characterized in that: a cross arm is fixed on the bottom surface at the butt joint of the bridge, and a connecting plate is fixed inside the butt joint of the bridge. The utility model has a simple structure, is easy to manufacture, and is convenient for construction and installation; its remarkable advantages are beautiful appearance, fast construction speed, high efficiency, high strength at the butt joint of the connection, and does not reduce the load-bearing capacity of the bridge. However, this device also cannot compact the fireproof materials to prevent the falling of the fireproof materials. For this reason, the utility model provides a finished bridge embedded channel box. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a finished bridge embedded channel box to compact the fireproof materials to prevent the falling of the fireproof materials.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A finished bridge embedded channel box includes an embedded channel body. One end of the embedded channel body is fixedly provided with a channel base, and the channel base is located around the embedded channel body. A water stop platform structure is also connected to the embedded channel body, and there is a gap between the water stop platform structure and the channel base. A sliding plate is detachably connected to the inside of the embedded channel body of the embedded channel body, and a plurality of partition plates are arranged at intervals on the sliding plate.

[0006] Further, the embedded channel body is formed into a channel-shaped structure by bending a galvanized steel plate. The thickness of the galvanized steel plate is 2-2.5 mm, and the edges on both sides of the embedded channel body are bent inward to form inner flanges.

[0007] Further, a plurality of through holes are arranged at intervals on the inner flange, and nuts are welded on the water stop platform structure. The nuts and the through holes are connected by screws.

[0008] Furthermore, the groove base is formed by welding 4 angle steels around the embedded groove body, and connection holes are also provided on the groove base.

[0009] Furthermore, convex strips are provided on both inner sides of the embedded groove body. A sliding rail gap is formed between the convex strips and the inner flange, and a cover plate is slidably arranged in the sliding rail gap.

[0010] Furthermore, anti-rust paint is sprayed on the embedded groove body, the groove base, the water stop table structure, the partition plate and the cover plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The structure of the present utility model is simple and convenient to manufacture. A groove base is provided on the embedded groove body to facilitate the fixed installation of the embedded groove. A water stop table structure is provided on the embedded groove. There is a gap between the water stop table structure and the groove base, and this gap is used to accommodate fireproof materials. On the one hand, since the water stop table structure and the groove base are located in the preset hole, the amount of fireproof mud can be reduced. On the other hand, due to the provision of the water stop table structure, the fireproof mud can be effectively blocked to prevent the fireproof mud from falling. Through holes are spaced on the inner flange, and the water stop table structure is connected to the through holes therein by screws, so that the position of the water stop table structure can be adjusted according to the depth of the preset hole.
