Self-heating type cement pipe pouring mould

Abstract

The invention discloses a self-heating type cement pipe pouring mould which comprises at least a pair of main and auxiliary sealing end covers, a heater, an inner circular column and an outer circularsleeve; the inner circular column, the outer circular sleeve, the main sealing end cover and the auxiliary sealing end cover are detachably matched to form a pouring space; the pouring space used forcontaining a steel reinforcement cage and concrete mortar; a cavity is formed in the inner circular column; an air inlet is formed in one end face of the inner circular column; a vent hole is formedin the other end face of the inner circular column; a plurality of hot air through holes are formed in the outer circular sleeve and do not communicate with the pouring space; the vent hole in the inner circular column communicates with the hot air through holes in the outer circular sleeve through connecting pipelines; and the heater is arranged in the cavity and is used for producing heat. The self-heating type cement pipe pouring mould has the beneficial effects that the pouring efficiency is improved substantially, pouring operation can be carried out in low temperature weather, and the influence on the pouring operation by the weather is overcome.

Description

technical field [0001] The invention relates to the field of pipes, in particular to a self-heating cement pipe casting mold. Background technique [0002] Cement pipes have an important application in the process of urban water pipe network construction. At present, most of the cement pipes are poured by reinforced concrete. The specific pouring method is to put the steel bars into the mold, and then pour the concrete mortar into the mold. After the concrete is completely condensed and dried, open the mold and complete the pouring. , The setting and drying time of concrete is highly related to the temperature of the surrounding environment. When the temperature of the concrete is too low (such as when the ambient temperature is very low in winter), the setting time of the concrete mortar is very long. Invention patent CN20162084967 provides a mold structure for cement pipe pouring. This mold cannot change the temperature of the environment during pouring. When encountering...

Invention patent CN20162084967 provides a mold structure for cement pipe pouring. This mold cannot change the temperature of the environment during pouring. When encountering low temperature weather, the solidification and drying time of the concrete mortar in the mold will become very long. If In order to speed up the setting and drying speed of concrete, the entire production pouring workshop must be heated up, which is too expensive
