Description
Technical Field
The invention belongs to the field of assembled building components, and particularly relates to a combined stair template.
Background
In the field of building construction, no matter cast-in-place concrete construction or prefabricated building components, the construction of stair templates cannot be avoided, and the stair templates are key construction tools for dimensional accuracy, surface impression and structural strength after the stair structures are formed. Without reasonable mold design, the stair structure can not be poured and prefabricated. The existing stair template mainly adopts two modes in structure.
The utility model provides a be semi-closed integral, its key feature is stair tread template does not establish the tread template, only designs the tread template, and the advantage is simple manufacture, and the gas permeability is good, and is low to the required precision, if the template material is bamboo offset plate, or the better plastic formwork of process property, this type stair template is basically made by constructor scene, if the metal material, then mostly advance or field weld and form, but no matter what kind of material preparation, the main shortcoming of this type of template is: firstly, because the tread is in a free state, the tread has insufficient density during pouring, and the stair tread strength is reduced even if the tread is vibrated; secondly, the surface of the stair tread is poor in flatness, rough and uneven after being formed, cannot meet the flatness and appearance requirements required by building construction quality, and needs to be plastered and leveled in the later period; the whole template has poor self-adaptive capacity and low reuse value. Because various stair structures are different, even if the stair structures of high-rise civil residences with high similarity are different along with different main body structures, the stair structures are different in the aspects of stair tread, tread width and the like, so that the stair is basically disposable and basically has no recycling price. The method is still used in many occasions in the actual cast-in-place construction at present.
The other type is a totally-enclosed integral type, which mainly means that the tread and the skirt of the stair adopt an integral template, and the template design mode has the advantages that the integral rigidity is higher, the compactness of the stair, particularly the concrete of the tread, is better than that of a semi-enclosed type after the stair is formed, and the precision is also higher. The template is mainly made of steel, and rarely made of aluminum. The main disadvantages are: the stair tread and the side surface are easy to generate bubbles after concrete is solidified due to the fact that the structural sealing performance is enhanced, and the appearance is influenced. Secondly, due to the integrity, after the concrete is poured, the requirement on form removal operation is high, the condition that the concrete body is damaged by the template is easy to occur, and the integral forming effect is influenced. High cost and no recovery value. Because the stair size variation is great, whole template is disposable basically and is scrapped promptly. At present, many occasions applying steel templates or aluminum templates are constructed according to the scheme. Fourthly, the whole template has larger weight, can be constructed smoothly generally depending on construction machinery such as a tower crane and the like, and has poor operability and safety.
