An object of the utility model is to provide a steel construction vestibule lower chord horizontal support device, the device adopt cancellation lower chord horizontal support, set up a portal steel frame through every internode, make horizontal load pass power clear and definite, also reduce simultaneously with the steel volume, improve stability and economic nature to solve the problem of proposing among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a steel construction vestibule lower chord horizontal support device, includes three equidistant supports that distribute of group, the upper end surface fixedly connected with lower chord truss of support, and the upper end surface equidistance fixedly connected with a plurality of groups door-type steel frame of lower chord truss, and both ends surface fixedly connected with wallboard wall roof beam around the door-type steel frame, the upper end surface fixedly connected with upper chord horizontal support of door-type steel frame.
By adopting the technical scheme, the device cancels the lower chord horizontal support, and the portal steel frame is arranged between every two sections, so that the horizontal load force transfer is definite, the steel consumption is reduced, and the stability and the economy are improved.
Preferably, the transverse wind load and the earthquake load are transmitted to the wall beam through the wall plate and transmitted to the door type steel frame through the wall beam, and the upper chord horizontal support is used as the top ends of two adjacent door type steel frames for connection and fixation.
Through adopting above-mentioned technical scheme, wallboard wall roof beam mainly used transmits device transverse wind load and earthquake load to the portal frame.
Preferably, a 4mm thick pattern steel plate is laid between the supports, and the pattern steel plate is not used as a walkway.
Through adopting above-mentioned technical scheme, the decorative pattern steel sheet is used for increasing the support and stabilizes.
Compared with the prior art, the beneficial effects of the utility model are that:
according to the device, the lower chord horizontal support is cancelled when the door type steel frame is added, the door type steel frame is arranged at every other node, transverse wind load and earthquake load are transmitted to the wall beam through the wall plate and the wall beam, transmitted to the door type steel frame through the wall beam and transmitted to the support through the lower chord truss, so that the horizontal load transmission is clear, the steel consumption is reduced, and the stability and the economical efficiency are improved.
