Description

Technical Field

[0001] The present application relates to the field of bridge construction, and in particular to a T-beam suitable for a simple support followed by continuous support process. Background Art

[0002] A T-beam refers to a beam with a T-shaped cross-section. The protruding parts on both sides are flanges, and the middle part is the beam rib. T-beams are often used in bridge engineering and play an important role.

[0003] Since the current T-beams are all made by casting, it is necessary to place tensioning teeth plates inside the T-beams. By connecting adjacent tensioning teeth plates and filling them with concrete, a process effect of first simple support and then continuous support can be achieved. The existing technical T-beams have complex internal structures and cumbersome processes, which greatly prolongs the production time of T-beams. Utility Model Content

[0004] In order to reduce the process complexity of T-beams and shorten the production time of T-beams, the present application provides a T-beam suitable for a simple support followed by a continuous process.

[0005] This application provides a T-beam suitable for a simple support followed by a continuous process, which adopts the following technical solution:

[0006] A T-beam suitable for a simply supported followed by continuous process, comprising a top plate, two flange plates, a beam rib, and a connecting structure for connecting to adjacent T-beams, wherein the top plate is arranged on the upper end surface of the beam rib, the two flange plates are respectively located on both sides of the top plate, the flange plates are metal parts, the connecting structure comprises a connecting plate and a connecting bolt, one end of the connecting plate is arranged on the flange plate, the tail of the connecting bolt passes through the flange plate and is threadedly connected to the adjacent flange plate, and the connecting bolt is used to thread the connecting plate to the flange plate.

[0007] By adopting the above technical solution, when adjacent T-beams are subjected to continuous processing, the adjacent T-beams are directly connected through connecting plates and connecting bolts, which greatly simplifies the steps of threading, connecting, tensioning, grouting, etc. in the traditional method, simplifies the process complexity of T-beam casting, and shortens the production time. The flange plate is a metal part, which makes it convenient for workers to drill holes in the flange plate without damaging the outer surface of the casting part, thereby improving the crack resistance of the T-beam.

[0008] Optionally, the top plate is provided with fixing parts for fixing the flange plate, and the fixing parts include a plurality of steel bars and a plurality of nuts. The steel bars penetrate the top plate along the width direction of the top plate, and the plurality of steel bars are evenly distributed on the top plate. The steel bars penetrate the flange plate, and one end of the steel bar is provided with a thread. The nut is threadedly connected to the steel bar and abuts against the side wall of the flange plate.

[0009] By adopting the above technical solution, during the installation of the flange plate, the staff first passes the flange plate through the steel bar and moves the flange plate toward the top plate until one end of the steel bar is exposed to the flange plate. When the nut is threaded onto one end of the steel bar, the flange plate is pressed against the top plate and the movement of the flange plate is restricted when the nut is tightened. The fixing structure is simple and easy for the staff to operate.

[0010] Optionally, the fixing part also includes a fixing strip and a plurality of fixing bolts. A snap-in groove is provided on the steel bar, and a matching groove is provided on the upper end surface of the flange plate. The matching groove is connected to the snap-in groove. The fixing strip passes through the matching groove, and the fixing strip is snapped into the snap-in groove. The fixing bolts are used to keep the fixing strip snapped into the snap-in groove.

[0011] By adopting the above technical solution, when the flange plate abuts against the top plate and the nut abuts against the flange plate, the staff can insert the fixing bar into the matching groove until the fixing bar is engaged in the matching groove and locked by the fixing bolt, so that the fixing bar is set on the steel bar. The fixing bar further limits the relative movement of the flange plate and the top plate, and reduces the force on the fixing bolt.

[0012] Optionally, the matching groove is provided with a guiding slope for guiding the fixing bar to move toward the clamping groove.

[0013] By adopting the above technical solution, since the length of the T-beam is long, the guiding inclined surface facilitates guiding the matching strip to smoothly enter the matching groove, thereby improving the installation time of the fixing strip.

[0014] Optionally, the beam rib includes two webs and a bottom plate, the two webs are arranged on both sides of the bottom plate, the webs are connected to the top plate, and the webs support the flange plate.

[0015] By adopting the above technical solution, the bottom plate is used to be connected to the support of the pier. The bottom plate has a larger area, which can improve the overall stability of the T-beam. The two webs are directly connected to the top plate and play a supporting role for the flange plate, which can further improve the reliability of the flange plate and reduce the situation where the flange plate is affected by gravity settlement and forms a step surface with the top plate.

[0016] Optionally, a limit plate is provided on the lower end surface of the flange plate, and an avoidance groove is opened on the side wall of the limit plate. When the flange plate abuts against the top plate, the end of the web facing away from the bottom plate is located in the avoidance groove.

[0017] By adopting the above technical solution, during the installation of the flange plate, the limit plate gradually approaches the web plate until the end of the web plate facing away from the bottom plate enters the avoidance groove. The web plate not only supports the flange plate, but the flange plate also limits the web plate through the limit plate, thereby further improving the connection strength between the flange plate and the web plate.

[0018] Optionally, a plurality of limiting bolts are provided on the limiting plate, and the limiting bolts pass through the limiting plate and are threadedly connected to the web.

[0019] By adopting the above technical solution, when the flange plate abuts against the top plate and the end of the web plate facing away from the bottom plate enters the avoidance groove, the staff can connect the web plate and the limit plate through the limit bolts, and the limit bolts further improve the connection strength between the web plate and the limit plate.

[0020] Optionally, the web is provided with reinforcing ribs for increasing strength.

[0021] By adopting the above technical solution, the reinforcing ribs are used to increase the lateral force of the web and improve the load-bearing capacity of the web, thereby improving the supporting effect on the flange plate and the top plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By connecting the structure and the flange plate of the metal parts, the adjacent T beams are easily connected, which reduces the internal structure of the T beam, making the casting of the T beam more convenient and improving the production time of the T beam.

[0024] 2. The fixing piece is used to connect the flange plate and the top plate, thereby improving the connection strength between the flange plate and the top plate;

[0025] 3. The beam rib is divided into a web and a bottom plate. One end of the web is connected to the avoidance groove of the limit plate, which improves the connection strength between the flange plate and the web. BRIEF DESCRIPTION OF THE DRAWINGS
