Description

Technical Field

[0001] The utility model relates to the field of steel components, in particular to a steel beam connecting piece. Background Art

[0002] The steel beam connector is a commonly used steel component, and its main function is to connect steel columns and steel beams. The existing steel beam connector mainly includes two parts: a steel column connecting sleeve and a steel beam supporting structure. The specific structure can be understood by referring to the structure disclosed in the utility model patent with application number "CN202323057915.X". However, during use, we found that there are some problems with the steel beam connector disclosed in the above patent, which is mainly caused by its second bearing plate 13. Specifically, although the second bearing plate can prevent the steel beam from being deformed due to downward pressure, The problem of falling off is that it is a protruding structure, and the steel beam is generally hoisted after the column is erected, so it will affect the lowering of the steel beam, resulting in inconvenient installation. Secondly, since its cross-sectional shape is adapted to the cross-sectional shape of the hollow cavity of the steel beam, when it is inserted into the end face of the hollow cavity of the steel beam, there will be friction between the two, which will cause difficulty in plugging and will also affect the lap installation of the steel beam. Therefore, it is necessary to improve the existing steel beam connectors so that they can have stable supporting capabilities without affecting the installation and erection of the steel beam. Utility Model Content

[0003] The utility model aims to provide a steel beam connector to solve the problem that the existing steel beam connector cannot take into account the stable supporting capacity and does not affect the installation and erection of the steel beam.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A steel beam connector includes a sleeve, wherein the hollow structural cross-section of the sleeve is adapted to the cross-section of a steel column, the sleeve is sleeved between the middle of the steel column and fixedly connected to the steel column by bolts, steel beam supporting plates are provided at the lower part of the outer surface of the sleeve, the steel beam supporting plates are arranged horizontally, and flank reinforcement connecting plates are provided on both sides of the outer surface of the sleeve, the spacing between two flank reinforcement connecting plates located on the same surface is greater than the width of the steel beam, and the flank reinforcement connecting plates are connected to the steel beam by bolts.

[0006] In this solution, the side wing reinforcement connecting plate is used to replace the original second bearing plate structure. Therefore, while taking into account the stable supporting force, it is also convenient for lifting the steel beam. Because the width between the two side wing reinforcement connecting plates on the same plane is greater than the width of the steel beam, the steel beam can be lowered smoothly until the bottom of its end face connects with the top surface of the steel beam support plate.

[0007] As a further preferred embodiment of the present invention, the top surface of the sleeve is flush with the top surface of the steel beam.

[0008] Since the steel beam may carry something, if the top surface of the sleeve is higher than the top surface of the steel beam, it may hinder the load. Therefore, the top surface of the sleeve is set to be flush with the top surface of the steel beam.

[0009] As a further preferred embodiment of the present invention, the bottom of the steel beam supporting plate is evenly provided with stiffening support plates.

[0010] Better support stability.

[0011] As a further preferred embodiment of the present invention, an extended support structure is also provided at the bottom of the sleeve, and the extended support structure includes a lower extension plate, the top of the lower extension plate is inserted into the insertion hole at the bottom of the sleeve through a connecting rod, bolt fixing holes are provided at the four corners of the lower extension plate, and a diagonal brace connecting plate is provided on the front of the lower extension plate.

[0012] When faced with some longer beams and heavier loads, an extended support structure can be used. The lower extension plate can be pulled down and then fixed to the column with bolts. The overall support structure can then be made more stable by setting diagonal braces.

[0013] As a further preferred embodiment of the utility model, bolt plates for connecting sleeves are further provided on both sides of the top of the lower extension plate, a bolt through hole is provided in the middle of the bolt plate for connecting sleeves, bolt holes suitable for the bolt through holes are provided on the bottom surface of the sleeve corresponding to the bolt through holes, and the lower extension plate can be positioned and connected with the sleeve by bolts.

[0014] The lower extension plate is fixedly connected to the sleeve when not in use.

[0015] Compared with the prior art, the utility model can achieve at least one of the following beneficial effects:

[0016] 1. In this scheme, the side wing reinforcement connecting plate is used to replace the original second bearing plate structure. Therefore, while taking into account the stable supporting force, it is also convenient for the lifting of the steel beam. Because the width between the two side wing reinforcement connecting plates on the same plane is greater than the width of the steel beam, the steel beam can be lowered smoothly until the bottom of its end face is connected with the top surface of the steel beam support plate.

[0017] 2. Since the steel beam may carry something, if the top surface of the sleeve is higher than the top surface of the steel beam, it may cause obstruction to the load. Therefore, the top surface of the sleeve can be set to be flush with the top surface of the steel beam.

[0018] 3. When facing some longer beams and heavier loads, you can use an extended support structure, pull the lower extension plate down, and then fix it to the column with bolts, and then set diagonal braces to make the overall support structure more stable.

[0019] 4. When not in use, the lower extension plate is fixedly connected to the sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
