The utility model has the characteristics of simple structure, just beating the prefab of beating conversely all be suitable for etc.
Description
Technical Field
The utility model relates to a building auxiliary assembly technical field, in particular to concrete prefabricated member pore-forming work piece.
Background
The concrete prefabricated member is widely applied to the fields of buildings, traffic, water conservancy and the like, and plays an important role in national economy. In order to improve the intensity of concrete prefabricated member, need carry out grout processing to the concrete prefabricated member, this just need leave the grout hole in advance when the manufacturing of concrete prefabricated member, however current grout hole is usually when the prefabricated member is made in advance, puts into the bellows of plastics, wait to the prefabricated member after stereotypeing, the bellows degradation to form the grout hole, this kind of mode at first belongs to the consumptive material, it is great to consume the energy, secondly plastics degradation can remain, be unfavorable for the effect of grout.
Disclosure of Invention
In order to achieve the purpose, the utility model provides a concrete prefabricated part pore-forming work piece, which comprises: the main column body is a cylindrical steel column, a first through hole is formed in the tail end of the main column body, spiral threads are formed in the side face of the main column body, and conical through holes are formed in the upper end and the lower end of the side face of the main column body. The sub-column body is a conical steel column, the sub-column body is fixedly connected with the main column body through conical opposite through holes, and the tail end of the sub-column body is provided with a second through hole.
Furthermore, the branch cylinder is provided with a base, the branch cylinder is connected with the base, and the second through hole at the tail end is arranged in the base.
The embodiment of the utility model provides a concrete prefabricated member pore-forming work piece compares with prior art, has following advantage: when the split-type column is used, the two split-type columns are conical steel columns, the two split-type columns can directly penetrate through the two conical holes in the main column, then the main column is placed in the prefabricated member, the top end of each split-type column is exposed out of the prefabricated member, and the split-type columns are provided with the bases, so that the fact that slurry does not enter the second through holes in the tail ends of the split-type columns can be guaranteed while the split-type columns are firmly fixed, and the fact that the second through holes are not blocked when the split-type columns are pulled out is guaranteed. Wait to the fixed shaping back of prefab, rotatory minute cylinder can extract a branch cylinder a little, forms the grout filling hole, and the rotatory main cylinder of rethread first through-hole takes out the main cylinder, forms the grout hole, can use the grout filling hole to inject the grout material, and the grout material spreads to the prefab after getting into the grout hole to improve the intensity of prefab. The mode can repeatedly use the pore-forming workpiece, has small loss, and directly forms a grouting hole once, thereby being beneficial to the grouting effect.
The utility model has the advantages of simple structure, convenient use, suitability for both forward beating and backward beating of the prefabricated member, low loss and the like.

Detailed Description
In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a concrete prefabricated member hole-forming workpiece, including: the main column body 1 is a cylindrical steel column, a first through hole is formed in the tail end of the main column body, spiral threads 3 are formed in the side face of the main column body 1, and conical through holes are formed in the upper end and the lower end of the side face of the main column body 1. The subsidiary cylinder 2 is a conical steel column, the subsidiary cylinder 2 is fixedly connected with the main cylinder 1 through conical opposite through holes, and the tail end of the subsidiary cylinder 2 is provided with a second through hole.
Furthermore, the sub-cylinder 2 is provided with a base 4, and a second through hole at the tail end of the sub-cylinder 2 is arranged in the base.
The working principle is as follows: the utility model provides a precast concrete prefab pore-forming work piece, when using, because two branch cylinders are the toper cylinder, can directly pass two toper pairs of perforation on the main cylinder with two branch cylinders, then place the prefab with the main cylinder in, and expose the prefab on branch cylinder top, because branch cylinder has the base, guarantee when can firmly fix branch cylinder that the terminal second through-hole of branch cylinder does not advance thick liquids to this guarantees that the second through-hole is unblocked when the branch cylinder is extracted. Wait to the fixed shaping back of prefab, rotatory minute cylinder can extract a branch cylinder a little, forms the grout filling hole, and the rotatory main cylinder of rethread first through-hole takes out the main cylinder, forms the grout hole, can use the grout filling hole to inject the grout material, and the grout material spreads to the prefab after getting into the grout hole to improve the intensity of prefab. The mode can repeatedly use the pore-forming workpiece, has small loss, and directly forms a grouting hole once, thereby being beneficial to the grouting effect.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
