A steam pipe steel-concrete combined base form for precast concrete

Abstract

The invention discloses a steam pipe reinforced concrete combined bottom mould for prefabricated concrete. The steam pipe reinforced concrete combined bottom mould is characterized by comprising a three-dimensional bottom mould frame (1) and a steam pipe (2), wherein a top plate (3) is arranged on the three-dimensional bottom mould frame; a concrete layer (4) combined with the top plate is arranged below the top plate; and the steam pipe (1) is embedded in the concrete layer (4). According to the invention, a reinforced concrete layer with a certain thickness is poured below the top plate of the three-dimensional bottom mould frame; furthermore, a welding shear nail is arranged, and therefore, the surface rigidity of a base and the integral stability are increased; deformation under the action of dead weight and external force can be reduced; in addition, in order to ensuring that steam heat energy is not blocked by concrete and the curing effect is not reduced, the steam pipe is embedded in the concrete layer, so that heat conduction of the frame type top plate is facilitated; simultaneously, after steam is introduced into the concrete layer of the bottom mould disclosed by the invention, the good heat-preservation capacity is provided because of heat accumulation effect; the use amount of steam can be reduced; and a relatively energy-saving production manner is realized.

Description

technical field [0001] The invention relates to the construction field, in particular to a steam pipe-steel composite base form for prefabricated concrete. Background technique [0002] The structure of prefabricated concrete houses is realized by prefabricated concrete components (referred to as prefabricated components), and the quality and precision of prefabricated components have a direct impact on the function and appearance of prefabricated buildings; the mold of prefabricated components plays an important role in the production cycle. The role determines the quality and production efficiency of the product. Generally, after the precast concrete is poured, effective curing measures will be taken. According to the needs, natural curing, hot mold curing, covering curing or steam curing can be selected to ensure that the concrete can reach the required strength within the predetermined time; A common practice in mold maintenance is to place the prefabricated part on the...

Problems solved by technology

Due to the vibration of the steam pipe steel bottom formwork in the production process, the dismantling of the upper mold, long-term repeated concrete loads, and the adsorption force of the prefabricated components during demoulding, etc., the deformation of the steel bottom formwork panel is often caused, and the product quality is reduced. Make the steel bottom mold unable to achieve the expected service life
