Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a connection structure for a concrete beam and a steel cover plate. Background Art

[0002] In construction sites such as tunnel construction safety research laboratories or water resource treatment plants, a large number of pump equipment are usually required for experiments or work. However, due to factors such as the size of the site and the convenience of disassembly and assembly of the pump equipment, during the early construction of the plant, the pump equipment room is usually partitioned and arranged in the underground building. At the same time, a steel cover structure is used to seal the top of the pump equipment room so that if the pump equipment is damaged in the future, the steel cover can be directly opened to lift the pump equipment out from the ground for replacement.

[0003] During the early construction of the pump equipment room, since the partitions between the partitions are mostly separated by concrete beams, and the steel cover plates are directly placed on the tongue and groove at both ends of the top of the concrete beams, the tongue and groove size at the connection between the top of the concrete beam and the steel cover plates is difficult to control, and it is easy for construction errors to affect the flatness of the tongue and groove at the top of the concrete beam, resulting in the steel cover plates being placed on the tongue and groove of the concrete beam. The tongue and groove gaps will be uneven in width, and when people pass from above, the steel cover plates will make strange noises due to the unstable local overlap between the steel cover plates and the concrete beam, thus affecting the use. In the existing technology, construction workers usually use the method of making a mortar layer or tiling to deal with the height difference of the top surface. However, for some locations with smaller height differences, the mortar layer is too thin and prone to cracking, and tiling is prone to causing local protrusions, affecting the overall appearance. As for the forming deviation of the side, it can only be smoothed by manual excavation. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a connection structure for concrete beams and steel cover plates. By placing the steel cover plate on the basis of the existing structure on the concrete beam, corresponding steel plate folding parts and edge protection angle steels are added according to the tongue and groove type of the concrete beam, so as to effectively improve the overall aesthetics and practicality of the steel cover plate placed on the concrete beam due to construction errors.

[0005] The utility model provides a connection structure for concrete beams and steel cover plates, comprising a concrete beam edge protection angle steel arranged at the bottom surface of the concrete beam tongue and a steel plate folding piece arranged at the top surface of the concrete beam tongue, the end of the steel cover plate is overlapped on the concrete beam edge protection angle steel, the steel plate folding piece is an inverted "U" structure as a whole, and the two ends of the bottom of the steel plate folding piece are respectively connected to the concrete beam edge protection angle steel located at the two ends of the concrete beam tongue in the width direction.

[0006] Further, the anchor bolt is arranged between the top surface of the concrete beam rebate and the top surface of the steel plate fold piece, and is used for fixedly connecting the top surface of the steel plate fold piece and the top surface of the concrete beam rebate.

[0007] Further, the anchor bolt is arranged in two in the width direction of the concrete beam and constitutes an anchor bolt group.

[0008] Further, the anchor bolt group is arranged in several groups in the length direction of the concrete beam.

[0009] Further, the top surface of the steel plate fold piece is flush with the top surface of the steel cover plate and is arranged with a gap from the top surface of the concrete beam rebate.

[0010] Further, the horizontal surface of the concrete beam edge protection angle steel is arranged on the bottom surface of the concrete beam rebate, and the vertical surface of the concrete beam edge protection angle steel is arranged on the side wall in the width direction of the concrete beam.
