Further, foam element is located in the periphery of the part bar section of rod member from an end of rod member, and the length of part bar section is greater than the degree of depth of preformed hole.
Further, the external surface of foam element is cylindrical surface.
Further, the cross section of foam element increases from top to bottom successively.
Further, the bolt prepared hole die also comprises fixture, and fixture is for being fixed on rod member by foam element.
Further, fixture is plastic sheeting, and plastic sheeting is wrapped on foam element, for foam element is fixed in to rod member.
Further, fixture comprises plastic film cover, and plastic film cover is set on rod member, and the preformed hole forming section comprises the foam beads filling part be filled between plastic film cover and rod member.
The application the technical solution of the utility model, the bolt preformed hole comprises rod member and foam element, and the size of rod member is less than the size of preformed hole, and the size that is around in the size of foam element of rod member periphery and preformed hole is suitable.The application the technical solution of the utility model, the roughness of the preformed hole after the dismounting foam element is larger, and back-grouting is combined firmly with former concrete, has alleviated the problem that is installed on the bolt looseness in preformed hole.Further, bolt prepared hole die of the present utility model is easy to take out the concrete from solidifying.Closer, because foam element is cheap, so reduced the cost of construction.
The accompanying drawing explanation
The Figure of description that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 shows the structural representation of the prepared hole die of the utility model embodiment.
The specific embodiment
It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, according to the utility model bolt prepared hole die, comprise rod member 1, the size of rod member is less than the size of bolt preformed hole; Foam element 2, foam element 2 is around in the periphery of rod member 1, and the size of the size of foam element and bolt preformed hole is suitable.
In the present embodiment, rod member 1 occupies headspace jointly with the foam element 2 that is around in rod member 1 periphery.When concreting, this bolt prepared hole die is positioned over to corresponding position in concrete.After concrete 4 solidifies, rod member 1 is extracted, then the foam element 2 in the bolt preformed hole is smashed to pieces, after pouring into water in the bolt preformed hole, the foam element 2 of being smashed to pieces is floating goes out the bolt preformed hole.Because foam element 1 is breakable member, so rod member 1 is easy to extract in the concrete 4 from solidifying, thereby solved mould of the prior art, be difficult for the problem of taking out in the concrete from solidifying, reduced labour intensity, improved significantly efficiency of construction.
Preferably, foam element 2 is surrounded and is formed by cystosepiment.In the present embodiment cheap cystosepiment is surrounded to the foam element of this bolt preformed hole, greatly reduce cost of production.
In the present embodiment, the length of rod member 1 is greater than the degree of depth of preformed hole.Rod member 1 is arranged in the above part of concrete 4 end faces for rod member 1 is taken out from concrete.
In the present embodiment, foam element 2 is located in the periphery of the part bar section of rod member 1 from an end of rod member 1, and the length of part bar section is greater than the degree of depth of preformed hole.Foam element 2 aligns with the end that rod member 1 is arranged in concrete 4, and the length that is around in the foam element 2 of rod member 1 periphery is greater than the degree of depth of preformed hole.Therefore, guaranteed rod member 1 directly with concrete 4 joints, avoided concrete 4 to cement and make the difficult problem of taking out of rod member 1 with rod member 1 from concrete.
In the present embodiment, the external surface of foam element 2 is cylindrical surface.The area that the bolt prepared hole die is arranged with the horizontal section of a section of foam element 2 equates.Alleviated the phenomenon of the bolt looseness produced as prepared hole die with large, lower young wedge shape timber suitable for reading in the prior art.
Preferably, the cross section of foam element 2 increases from top to bottom successively.The bolt prepared hole die is arranged with the increase successively from top to bottom of the horizontal section of a section of foam element 2, young on formed preformed hole, end opening is large, has further alleviated the phenomenon of the bolt looseness produced as prepared hole die with large, lower young wedge shape timber suitable for reading in the prior art.
Preferably, the bolt prepared hole die also comprises fixture 3, and fixture 3 is for being fixed on rod member 1 by foam element 2.Use fixture 3 that foam element 2 is fixed on rod member 1, make construction convenient, operating efficiency is provided.
In the present embodiment, fixture 3 is plastic sheeting, and plastic sheeting is wrapped on foam element 2, for foam element 2 is fixed in to rod member 1.Plastic sheeting is cheap, is conducive to reduce construction cost.
According to another embodiment of the present utility model, fixture 3 is plastic film cover, and plastic film cover is set on rod member 1, and the preformed hole forming section is the foam beads filling part be filled between plastic film cover and rod member 1.
In the present embodiment, the size of the size of plastic film cover and bolt preformed hole is suitable.Plastic film cover is fixed on foam beads the periphery of rod member 1.The shape of the preformed hole forming section be comprised of foam beads can be flexible and changeable, and formed bolt preformed hole do not have dead angle, makes the concrete that secondary is built be combined firmly with preformed hole.
By above description, can be found out, embodiment of the present utility model has realized following effect: the bolt preformed hole comprises rod member and foam element, and the size of rod member is less than the size of preformed hole, and the size that is around in the size of foam element of rod member periphery and preformed hole is suitable.Apply the technical solution of the utility model, avoided being installed on the problem of the bolt looseness in preformed hole.Further, bolt prepared hole die of the present utility model is easy to take out the concrete from solidifying.Closer, because foam element is cheap, so reduced the cost of construction.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
