Embodiment Construction

[0028] It is a common layout form to arrange the corridor 2 of the steel belt conveyor above the stockyard. The construction of the corridor 2 generally uses a truck crane, and the construction of the stockyard with a large-span figure-eight truss structure as the main body also requires the use of a truck crane. Therefore, the construction of the two can be combined together, and the corridor 2 structure just above the stockyard can just be used as an auxiliary platform for the construction of a large-span figure-eight truss structure, and the present invention just utilizes the corridor 2 above the stockyard, A new large-span figure-eight truss structure stockyard construction method is proposed.

[0029] Such as figure 1 , figure 2 As shown, the method includes the following steps.

[0030] a. Lift the corridor 2 above the stockyard first, and fix the corridor 2 on the brackets 1 at both ends. The structure of corridor 2 and bracket 1 is detailed in image 3 , Figure...

Abstract

The invention relates to a construction method of a large-span splayed truss structure stockyard, which comprises the following steps of: constructing the large-span splayed truss structure stockyard by utilizing a vestibule above the stockyard, dividing a large-span splayed truss into three parts, respectively hoisting, mounting a movable butt-joint platform on the vestibule, and mounting a movable butt-joint platform on the vestibule; and the horizontal truss part which is lifted firstly is fixed to the movable butt joint platform, then the inclined truss parts on the two sides are lifted to be spliced with the horizontal truss part, and a complete large-span splayed truss structure is formed. The existing vestibule structure above the stock yard is fully utilized, the hoisting difficulty of the large-span splayed truss is reduced, the shape and position precision of the large-span splayed truss structure can be easily guaranteed, the safety risk in the construction process is low, and the cost is low.

Description

technical field [0001] The invention relates to a truss structure construction technology, in particular to a large-span figure-eight truss structure stockyard construction method. Background technique [0002] The eight-shaped stockyard is a relatively common ore storage yard structure in mine construction. It is composed of multiple large-span eight-shaped truss structures. The trusses are connected by a large number of supports and purlins, and a steel belt conveyor corridor is arranged above them. Due to the large span of the figure-eight truss in the stockyard, the general method of hoisting is to splice the ground together and then use multiple truck cranes to lift it, which can reduce high-altitude docking. However, it is difficult to assemble the figure-eight truss on the ground as a whole. It can only be spliced ​​after being laid flat, and then lifted by a crane and turned over to stand up. The large-span figure-eight trusses after assembly will affect the positio...
