Embodiment Construction

[0021] A kind of construction method of prefabricated T-beam waterproof layer, is characterized in that: comprise the steps:

[0022] ① Manufacture of hoisting trolley: First, use 83mm and 50mm hot-rolled seamless steel pipes 2 and 3 to make a simple truss. The working platform at the lower part of the truss is made of channel steel as frame 5, and a 12mm thick steel plate with an area equal to the channel steel frame is welded on the frame 4. For ease of movement, 4 wheels 6 are welded under the frame. An I-beam is welded on the top of the truss to make the track 1, and a 1t electric hoist 7 is installed on the track. Equipped with a trolley 8 and a distribution box for loading concrete with the trolley. The electric hoist can lift the trolley to move up and down, forward and backward, and deliver concrete to the bridge deck; (such as figure 1 , 2 , 3 shown)

[0023] ②During construction, first put the hoisting trolley in place and fix it; (such as Figure 4 shown)

Abstract

The invention relates to a construction method of a prefabricated T-beam waterproof layer. The construction method comprises the following steps of (1) manufacturing a lifting trolley: firstly making a simple truss frame with thermo-bonded seamless steel tubes, making a framework through channel steel at the lower part of the truss frame, welding a steel plate to the framework to be used as a working platform, welding I-steel to the top of the truss frame to be used as a railway, mounting an electric hoist on the railway, and allocating a wheelbarrow for loading concrete and a distribution box on the trolley; (2) during construction, firstly enabling the lifting trolley to reach the specified position, and fixing the lifting trolley; (3) transporting the concrete into the wheelbarrow through a tank truck, and lifting the concrete to a bridge floor through the electric hoist; (4) then manually pushing the concrete to the specified position for construction; and (5) after the construction is completed, manually pushing the trolley to the next beam. Through the adoption of the method disclosed by the invention, the problems that the waterproof construction of the bridge floor is difficult and the cost is high can be effectively solved, the construction becomes easy, and besides, the cost is reduced.

Description

Technical field: [0001] The invention belongs to a building construction method, in particular to a construction method of a prefabricated T-beam waterproof layer. Background technique: [0002] The construction method of the waterproof layer protective layer of the T-beam bridge deck generally adopts steam crane or gantry crane to lift and transport the concrete of the waterproof layer protective layer. Its main disadvantages: 1. It is necessary to make a hopper for concrete when using a steam crane or a gantry crane. During cross-area construction, the gantry crane can lift the hopper and move, but the moving speed is very slow. Affect the work efficiency of beam lifting. At the same time, depreciation charges are too high. 2. When the steam crane is used for cross-area construction, a loader is required to move the hopper, which makes the preparation time too long and the rental fee too high. Invention content: [0003] The purpose of the present invention is to ove...
