A "girder bolt"!
A bolt for a girder is a bolt that is cast in place with the cap. Therefore the bolt is concreted into the cap of the substructure of the bridge. The girder is then set on top of bearing pads, on top of the cap, in between the girder bolts. The bolts are there to keep the ends of the girders from moving side to side.
girder is the main horizontal beam . the joists which are usually smaller, are connected to the girders and are supported by the girder.
That girder will be used for support.
beam girder
how do you calculate hogging of i girder
plate girder is a vertical section which supports the beam while gantry girder is a horizontal section which supports the othet small beams.
A building girder can be U shaped for several different reasons. The shape of the building girder will determine how much weight the girder can carry and how much side to side stress it can withstand.
Based on CMAA (Crane Manufacturers Association Of America) specifications, both single & double girder are equally rigid, strong & durable. This is because single girder cranes use much stronger cross girders than double girder cranes, and single girder cranes have lateral bracing, unlike double girder cranes.

girder isa a large strong piece of metal or wood.

Zhengzhou Huazhong Construction Machinery Co., Ltd. (ZZHZ). Thanks for asking the question about honeycomb girder on Answers, because it is one of our patents. Honeycomb girder developed for gantry crane and bridge girder launcher by our company -----Zhengzhou Huazhong Constrution Machinery Co., Ltd ( short for ZZHZ ), which is a new type of main girder and has been widely used in crane fields. The reason why increasing people are looking for honeycomb girder type cranes because they are unique and reliable.Brief introduction on honeycomb girder gantry crane and bridge girder launcher are as following.1. Why we called it honeycomb girder?The main girder is honeycomb girder.For honeycomb girder, it means many hexagonal holes which looks like honeycombs in the main girder, with which the air current could pass through the hole when the launcher works high above the ground. Then it greatly reduces wind impact on the gantry crane, so it is quite safe.2. What are Advantages of honeycomb girder?a. compared with truss girder, safer!Steel plate welded with steel plate (honeycomb girder) is safer than point to point welding (truss girder). If there is an occasional bad welding, the honeycomb girder will not be affected too much, while if it happens on truss girder crane, the whole girder may lose stability and cause an accident.b. Compared with box girder, safer!When box girder crane works high above the ground, the heavy wind will have a great impact on it and make it unsafe. While the honeycomb girder launching gantry has reasonable design(honeycomb hole) to reduce wind impact. Besides, it has a light self weight and cost lower.3. Featuresa. quite safeb. high wind-resistance, high stiffness and low deflectionc. light self weightd. flexible legse. unique and reliable pin connection, easy installation and disassemblyf. high quality imported electrical elements are used4. LimitationAt present, if material to be lifted is less than 250t, a honeycomb girder can be used.Generally speaking, with its own characteristics, the new style honeycomb type gantry crane and bridge girder launcher from ZZHZ will be the flavor of the market.Please find more information about honeycomb girder on website of Zhengzhou Huazhong Construction Machinery Co.,Ltd.
