Embodiment

[0029] In order to make reinforced concrete cooling tower scale test model, the present invention can complete model making according to the following steps:

[0030] (1) Design of model template. ① According to the space size of the cooling tower model, the cooling tower formwork is divided into N layers along the height direction of the model, and the height of each layer of formwork is determined respectively. Among them, the first layer of formwork is the formwork layer of the cooling tower model pillar, and the height of the formwork is the same as the height of the model pillar. The second to (N-1) layers are the tower model formwork layer, and the height of each layer of formwork is 100-250mm. The upper layer (that is, the Nth floor) is the top formwork layer of the tower model, and its height is the sum of the height of the cooling tower model minus the height of the former (N-1) layer formwork, such as figure 1 shown; ②According to the maximum plane size of the cooli...

Abstract

The invention relates to a method for manufacturing an ultra-large reinforced concrete cooling tower reduced scale test model. According to the spatial size of the cooling tower reduced scale model, hard plastic foam formworks of the reduced scale model are cut layer by layer through an electric heating wire, a supporting column framework is welded through iron wires of different types, a meridian-direction iron gauze and a circumferential iron gauze in a tower cylinder are welded after all the inner formworks are installed, then outer formworks are installed in sequence, and a cylinder body is obtained through pouring. Compared with the prior art, the method has the advantages that the manufactured cooling tower reduced scale model can continuously change on the aspects of radius and thickness in the horizontal plane along with the change of the height of the model, the outer surface of the test model is smooth and continuous, the geometric size of the model especially the thickness of the cooling tower cylinder can reach control accuracy at the millimeter level, the method is easy and convenient to operate and low in cost, and the required materials can be easily purchased in the market.

Description

technical field [0001] The invention belongs to a method for making an engineering structure test model, in particular to a method for making a scaled-down test model of a super-large reinforced concrete cooling tower. Background technique [0002] The natural draft cooling tower is a thin-walled structure with a large space. Due to the special shape of the structure, its safety performance has been widely concerned by people. In the safety performance analysis of reinforced concrete cooling towers, experimental research is a very important part. However, at present, the production of this kind of space thin-walled structure test model has become a difficulty that restricts the extensive development of cooling tower test research. In order to correctly reflect the geometric characteristics and force characteristics of the cooling tower, it is necessary that the tower of the cooling tower scale test model can imitate the prototype cooling tower as a rotating hyperbolic parabo...
