The invention discloses a cap type stringer integral positioning device which comprises an overturning frame, overturning shafts are arranged at the two ends of the overturning frame respectively, a plurality of cross beams are arranged in the overturning frame, and the bottoms of the cross beams are connected with positioning clamping plate assemblies through connecting plates and clamping plate connecting pieces. The positioning clamping plate assembly comprises a clamping plate body, clamping devices and guiders, clamping positioning grooves with the number consistent with that of the cap-shaped stringers are formed in the clamping plate body along the arc-shaped bottom edge, and the clamping devices and the guiders with the number consistent with that of the cap-shaped stringers are arranged on the clamping plate body. According to the cap-shaped stringer integral positioning device, the combination efficiency and the positioning precision of the cap-shaped stringer and the skin are improved, and by means of the device and the method, the cap-shaped stringer can be integrated on the cap-shaped stringer integral positioning device firstly; through overturning of the overturning positioning frame, the whole device for loading the cap-shaped stringer and a skin mold are integrally and accurately combined at a time by utilizing a travelling crane, and the cap-shaped stringer can be integrally shaped, clamped, overturned and accurately positioned and assembled on the skin.

The invention provides a wooden bridge and an installation process thereof, and belongs to the technical field of viaducts. The wooden bridge comprises: a plurality of bridge column bearing platforms; multiple bridge column assemblies which are arranged on the upper sides of the multiple bridge column bearing platforms correspondingly, wherein the multiple bridge column assemblies and the bridge column bearing platforms are in one-to-one symmetry; multiple sets of bridge column wrapping decoration assemblies which are arranged on the front sides and the rear sides of the multiple sets of bridge column assemblies correspondingly, wherein protection on the front sides and the rear sides of the bridge column assemblies is achieved; longitudinal beam assemblies which are arranged on the upper sides of the two longitudinal bridge column assemblies respectively; a plurality of groups of cross beam assemblies which are respectively arranged between the two groups of longitudinal beam assemblies; and multiple groups of bridge floor assemblies which are arranged on the upper sides of the multiple groups of cross beam assemblies. According to the device, the wooden bridge can be installed through the rubber hammers and the screws, so that the wooden bridge can be installed more simply and safely, and students can use the device to install the viaduct in a short time.

The invention relates to a steel beam platform structure for a C-shaped stockyard, and belongs to the technical field of building structures. The steel beam platform structure comprises a plurality of supporting seats arranged at intervals in the longitudinal direction of the stockyard, at least two branches distributed in the transverse direction of the stockyard are arranged at the upper parts of the supporting seats, prefabricated steel structure cross beams are arranged at the tops of the branches, prefabricated steel structure longitudinal beams arranged in the longitudinal direction of the stockyard are arranged on the prefabricated steel structure cross beams, a platform body is arranged on the prefabricated steel structure longitudinal beams, and the platform body is formed by laying a plurality of prefabricated platform plates. The supporting seats with the plurality of branches are adopted, so that the overhanging length of the cross beams is shortened, and the stress of the cross beams is improved; by the adoption of the assembly type platform structure, the working procedures of on-site formwork erecting, formwork removing, reinforcing steel bar plate binding and the like are reduced, on-site construction and manufacturing of platform beam plate prefabricated parts are conducted synchronously, the construction period is shortened, and the construction auxiliary cost and the engineering investment cost are reduced.
