According to the method, aiming at the problem that a combined node position of a steel web member and a concrete inner chord member at a node position is easy to damage at present, arrangement of shear keys in a node structure is reduced through an integrated node; wherein through hole structures reserved on the joints are combined with steel bars to connect a bridge steel bar framework structure on one hand, and a pin structure is formed by concrete filled with the through holes on the other hand, so that the connection strength of the joints and a bridge concrete main body structure is improved; The structure comprises an integrated node, wherein the node comprises a chord member and a web member of which the end part is butted with the chord member; the chord member is circumferentially coated with a concrete layer, and the chord member is connected with a shear nail embedded in the concrete layer; a plurality of first through holes perpendicular to the axial direction of the chord members are formed in the positions, connected with the chord members, of the chord members and the web members, and the first through holes are matched with first steel bars penetrating through the joints and embedded in the concrete layer; the chord member is also provided with a second through hole, wherein the axis of the second through hole is vertical to the axis of the first through hole.

The invention provides an automatic take-up tensioner, belongs to the technical field of machinery, and solves the problem that a brake baffle may be stuck when the conventional automatic take-up tensioner swings. The automatic take-up tensioner comprises a belt axis, a bracket, a handle, a barrier component 1 and a barrier component 2, wherein a swirling spring is arranged between the bracket and the belt axis; the belt axis has a trend of moving to the direction of winding a binding strap under the action of the swirling spring; and the barrier component 2 is fixedly connected with a damping mechanism which acts on ratchet wheels. When the tensioner is in an ungirding state, the damping mechanism acts on the ratchet wheels, and the damping force of the damping mechanism is greater than the elastic action force of the swirling spring, thus, the damping mechanism can eliminate the damping force against the ratchet wheels through exogenous action. The automatic take-up tensioner has the advantages of low cost, little occupied space, high using stability and compact and beautiful structure.
