Problems solved by technology

Therefore, there are several problems: 1. High cost: a lot of labor for repeated disassembly and assembly, large cutting loss, easy deformation and decay of wood after being exposed to wind, sun, and rain, and less frequency of use; 2. Slow progress: workload Large; 3. Poor quality: rough surface, easy to deform, and many seams; 4. Waste of a lot of national timber resources

Embodiment Construction

[0053] First, the factory produces various models according to specifications or culvert drawings, and then stacks them to the construction site for assembly.

[0054] Foundation assembly: fix the tripod (1) on the iron plate with screws, and fix the middle corner on the steel support (4) to form each template, connect the four corners with screws, and insert the embedded steel bars (2) into the holes of the iron plate. ), when assembling the second and later concrete models, fix one end of the two side molds on the previous piece of concrete with a bubble screw and a tie rod (the tie rod can also be replaced by multiple iron wires) (3), insert ground pins (6) ), brush a small amount of engine oil on the inner wall of the iron plate, stick a foam plate on the inner wall of the iron plate, and fill the concrete with a ruler to level the surface of the concrete (5).

[0055] Foundation transfer: remove the back template (1), when removing the second and subsequent concrete models, r...

Abstract

The invention relates to a kind of cast-in-place concrete model which can be factory produced and moved wholly. Put it into serial production in various kinds of specifications by the factory, transport the spread parts in pile to the building site, assemble them nito model, pour the concrete, move the model wholly after the concrete has solidified. Then we can pour the next section of concrete, and needn't break up all of them and reset repeatedly.

Description

Technical field [0001] The invention relates to a model of cast-in-place concrete, in particular a model of cast-in-situ culvert concrete. Background technique [0002] At present, cast-in-situ concrete mainly uses wooden molds. The board surface is made up of multiple wooden plywood boards and nailed to the wood with iron nails. In order to prevent the formwork from bending, a large number of wooden throws are used behind the formwork and a large number of wooden piles are cast on the ground. There are also a few molds that use iron molds, and their structure is basically the same as that of wooden molds. When two or more concretes of the same specification are to be poured, they must all be disassembled and then installed in the next position. For example, for a 100-meter-long culvert, there must be a settlement joint every 4-6 linear meters, and the walls on both sides need to be repeatedly disassembled and assembled 40 times. Therefore, there are several problems: 1. High cos...
