Referring to fig. 1-5, the utility model provides a tool for grouting a sleeve, which comprises a rubber cylinder 2, wherein a through round hole 21 is formed in the middle of the rubber cylinder 2, a bolt 1 is arranged in the through round hole 21, the rubber cylinder 2 is connected with the bolt 1 through a nut 4, and a gasket 3 is arranged between the nut 4 and the end part of the rubber cylinder 2.
When the embodiment is used, in the prior art, expansion bolts are adopted for connection and positioning between the prefabricated column bottom die and the grouting sleeve, in the positioning process, the nut is required to be screwed down by using an electric spanner to quickly rotate, and the expansion is promoted to generate friction grip by utilizing wedge-shaped inclination, so that the fixing effect is achieved. However, the expansion bolt is not very reliable, if the load is subjected to larger vibration, the phenomenon of loosening can possibly occur, and the bottom of the grouting sleeve cannot be tightly covered after the expansion of the expansion iron pipe, so that the grouting sleeve can be permeated into the grouting sleeve in the concrete pouring process, and the quality of the finished product of the precast column is seriously affected. Therefore, in order to solve these problems, the present embodiment proposes a tool for using a grouting sleeve. Specifically, the tool consists of four parts, namely a bolt 1, a nut 4, a gasket 3 and a rubber cylinder 2. The center of the rubber cylinder 2 is provided with a through round hole 21, so that the bolt 1 passes through the through round hole 21 at the center of the rubber cylinder 2, the other side of the rubber cylinder passes through the tail of the bolt 1 by using the gasket 3, and the rubber cylinder is tightly sleeved with the nut 4, so that the gasket 3 is tightly pressed at the bottom of the rubber cylinder 2. In the positioning process, a spanner is used for tightening the nut 4, so that the gasket 3 is tightly pressed at the bottom of the rubber cylinder 2, and the rubber cylinder 2 placed in the grouting sleeve expands under the action of external force extrusion until the joint surface of the rubber cylinder and the grouting sleeve is completely compact. So far, the connection and fixation of the grouting sleeve using tool and the prefabricated column bottom die are completed. When the nut 4 is unscrewed and the external force is removed, the rubber cylinder 2 is restored, and the grouting sleeve can be taken out from the bottom for recycling.
In this embodiment, adopt manual spanner can accomplish work, the dismouting is simple rapid, labour saving and time saving.
In the present embodiment, the bolt 1 and the nut 4 are the hexagonal bolt 1 and the hexagonal nut 4 which are matched with each other, and of course, the use of the hexagonal bolt 1 and the hexagonal nut 4 is not limited as long as the interconnection can be achieved.
In this embodiment, in order to ensure that the bolt 1 can pass through the through hole 21 in the center of the rubber cylinder 2, the diameter of the through hole 21 is 2mm larger than the diameter of the hexagonal bolt 1. Of course, the diameter is not limited to 2mm larger than that of the hexagonal bolt 1, as long as the hexagonal bolt 1 can be ensured to pass through the through-hole 21, and the hexagonal bolt 1 may have a relatively stable diameter within the through-hole 21, for example, the diameter of the through-hole 21 is 1 to 3mm larger than that of the bolt 1.
In this embodiment, in order to facilitate the removal of the tooling, a cap-shaped rubber cylinder 2 is designed, i.e. the rubber cylinder 2 comprises a cylindrical section 22 and a conical cylindrical section 23 which are connected with each other. The cylindrical section 22 and the conical section 23 are integrally formed. In use, the cylindrical section 22 is within the grout sleeve, while the visor section, i.e., the conical section 23, is not. After the nut 4 is unscrewed and the external force is removed, the conical column section 23 applies force to the rubber cylinder 2, so that the rubber cylinder 2 is taken out from the bottom of the grouting sleeve, and the grouting sleeve is convenient for next use.
The smallest diameter of the conical column section 23 is larger than that of the cylindrical section 22, so that the rubber cylinder 2 forms a cap shape, and the rubber cylinder is convenient to take out.
In addition, the external diameter of cylinder section 22 equals the internal diameter of grout sleeve, is convenient for insert the rubber section of thick bamboo 2 in the reservation round hole 5 of prefabricated post die block inboard, simultaneously, is convenient for the expansion of rubber section of thick bamboo 2 closely laminate with grout sleeve inner wall, effectively prevents the seepage of grout, improves the finished product quality of prefabricated post.
As a further description of the above embodiments, the washer 3 is disposed between the nut 4 and the end of the conical post section 23.
When the embodiment is used, the arrangement of the gasket 3 can increase the contact area between the nut 4 and the rubber cylinder 2, reduce the pressure, prevent the nut 4 from loosening, and protect the parts and the bolt 1.
In summary, the working process of the tool provided by the utility model is as follows:
by adopting the tool for using the grouting sleeve, the prefabricated column is generally manufactured in a horizontal beating mode, a bottom die of the prefabricated column is cleaned, a proper cap-shaped rubber cylinder 2 is selected according to the size of the grouting sleeve, a hexagonal bolt 1 is used for penetrating through a through round hole 21 reserved in the center of the cap-shaped rubber cylinder 2 with reasonable shape selection, and then the connected hexagonal bolt 1 and the cap-shaped rubber cylinder 2 are inserted into a reserved round hole 5 in the inner side of the bottom die of the prefabricated column. And then the cap-shaped rubber cylinder 2 is inserted from the bottom of the grouting sleeve, and the top of the grouting sleeve is screwed and fixed with the vertical steel bars of the prefabricated column. And then inserting the hexagon bolt 1 extending out of the top of the grouting sleeve into the gasket 3, sleeving the hexagon nut 4, and screwing the hexagon nut by using a manual wrench, so that the gasket 3 is tightly pressed at the bottom of the cap-shaped rubber cylinder 2. Because the extrusion effect of external force is received, the cap-type rubber cylinder 2 is deformed in the grouting sleeve, and expansion is generated, and a large friction force is formed in the grouting sleeve until the cap-type rubber cylinder is completely attached to the bottom of the grouting sleeve, so that the grouting sleeve is connected and fixed with the bottom die of the prefabricated column by using a tool. And then splicing the prefabricated column side dies, pouring concrete after the completion, demoulding after the cured concrete reaches the specified strength, screwing out the hexagonal nut 4 by using a manual wrench, recovering the cap-shaped rubber cylinder 2 once the external force is removed, and taking out the cap-shaped rubber cylinder 2 from the bottom of the grouting sleeve to complete the production of the prefabricated column.
In conclusion, in the utility model, the assembly and disassembly of the tooling are simple and rapid, time and labor are saved, the leakage of cement paste can be effectively prevented, and the quality of the finished product of the prefabricated column is greatly improved; meanwhile, the tool is low in damage rate and reusable, and production cost is greatly reduced. Therefore, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.
