PC wallboard mould used for concrete prefabricated component production line

Abstract

The invention belongs to the technical field of building products, in particular to a PC wallboard mould used for a concrete prefabricated component production line. The mould comprises an inner cavity wall module, an outer cavity wall module and a positioning hole module, wherein the positioning hole module comprises a base; a transverse supporting arm is extended from the base; a penetrating hole is formed in the top end of the transverse supporting arm; the positioning hole module further comprises a positioning barrel and a threaded sleeve; the top end surface of the positioning barrel isfixedly connected to the lower hole end surface of the penetrating hole in a resisting mode, and the positioning barrel and the penetrating hole are coaxially formed; inner threads are arranged at a sleeve cavity of the threaded sleeve; a positioning bolt passes through the penetrating hole and the positioning barrel, and is in threaded fit to the threaded sleeve; and a matched surface of the threaded sleeve and the positioning barrel is higher than or equal to or lower than the top end surface of the outer cavity wall module. The mould has the advantages of being simple, convenient and quickto operate, and low in manufacturing cost, so that later-stage assembly needs at equal height and the same plane of a manufactured prefabricated wallboard can be guaranteed while the prefabricated wallboard is formed.

Description

technical field [0001] The invention belongs to the technical field of building products, and in particular relates to a PC wall panel mold used in a concrete prefabricated component production line. Background technique [0002] In recent years, with the development of the economy, the construction industry has paid more and more attention to energy consumption and environmental pollution. The construction of traditional reinforced concrete structures in the field of construction often adopts on-site wet construction. This construction method not only consumes a large amount of wood as bottom formwork and support materials, but also consumes a lot of energy, and construction efficiency is low. It takes a long time, produces noise and dust, and has great pollution to the surrounding environment. Therefore, in recent years, the construction field has begun to introduce the concept of modular houses. Modular houses are different from traditional house construction. Usually, ...

Problems solved by technology

However, due to the complex construction environment on site, the flatness of the floor slab as the foundation and even the ground is questionable, which brings troubles to the construction operation on site

At the same time, during the grouting process of closing the warehouse and when the cement mortar hardens, corresponding internal stress will also be generated. This internal stress may also cause changes in the positions of two adjacent prefabricated wall panels. At present, it can only be fixed by setting external support frames. Realization, not only occupies a large area, but also has adverse effects on construction cost and construction time

In addition, because the prefabricated wallboards are all directly molded when making the prefabricated wallboards, the splicing edges of the two adjacent prefabricated wallboards are all smooth surfaces, which makes it possible to fill in the matching gap between the two adjacent prefabricated wallboards. When using cement mortar, it is often difficult to ensure the connection tightness between the cement mortar and the prefabricated wall panels, and even endanger the overall structural strength of the modular house in severe cases
