The utility model further improves and is, described positioning bar is arranged at the cental axial position of described sleeve body.
The utility model further improves and is, the two ends of described dowel are welded in the inner side barrel of described sleeve body.
The utility model further improves and is, the inner side barrel of the second end of described sleeve body is welded with brace rod, and described positioning bar welds mutually with described brace rod.
The utility model further improves and is, the first end of described sleeve body is provided with handle, and described handle is the handle reinforcing bar that two ends are welded in the inner side barrel of the first end of described sleeve body.
The utility model, owing to have employed above technical scheme, makes it have following beneficial effect:
1) mode that positioning bar is set in the inside of sleeve body is adopted, sleeve body is positioned the hole to be provided position of structure floor, traditional employing baked wheaten cake silk is replaced to carry out the mode of colligation fixed muffle and floor, both the operation of sleeve body Embedment Construction had been simplified, the time shortening the hole to be provided construction of structure floor of high degree, can also ensure shaping after the hole wall of floor slab preformed hole smooth clean and tidy, there is no a mao defect;
2) sleeve body adopts up big and down small form that the proposition of sleeve body when concrete initial set can be made more convenient, and hole is more conducive to the construction of waterproofing;
3) positioning jack positioning bar and stay in place formwork offered closely retrains, the integral shift of preset sleeve and the skew of bottom can be avoided in process is vibrated in concreting, ensure that the construction precision that hole to be provided is constructed, and decrease the later stage because hole to be provided offsets the extra cost of the Pipe installing caused.
Accompanying drawing explanation
Fig. 1 is the structural representation of the preset sleeve of threading of the present utility model.
Fig. 2 is the cross-sectional view of the using state of the preset sleeve of threading of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
Consult shown in Fig. 1 and Fig. 2, the preset sleeve 10 of threading of the present utility model is primarily of sleeve body 11, for sleeve body 11 being positioned the positioning bar 12 on stay in place formwork and being used for the dowel 121 be fixed in sleeve body 11 by positioning bar 12 formed, be mainly used on the stay in place formwork 13 at the hole to be provided place by positioning bar 12, sleeve body 11 being positioned floor, when floor concrete casting completes also initial set, in concrete, propose sleeve body 11, just floorslab concrete after shaping can form the hole to be provided supplying to plug pipeline.
Sleeve body 11 is the column-shaped barrel of both ends open, and the barrel dliameter of sleeve body 11 reduces to the second end 112 gradually from first end 111, in use, guarantee the inside of the concrete structure that the second end 112 of the sleeve body 11 that barrel dliameter is less is deeply built in advance, in the present embodiment, second end 112 of sleeve body 11 is placed on stay in place formwork 13, when floor concrete casting completes also initial set, the structure that sleeve body 11 is up big and down small, the proposition of sleeve body 11 can be convenient to, guarantee the forming quality of hole to be provided, and make hole to be provided more be conducive to the construction of waterproofing.
Dowel 121 is horizontally disposed with, two ends are welded in the inner side barrel of sleeve body 11, positioning bar 12 is vertically arranged at the cental axial position of sleeve body 11, positioning bar 12 has the link that is welded in dowel 121 and for plugging the positioning end being fixed to the positioning jack 14 be opened on stay in place formwork 13, the positioning end of positioning bar 12 extends the second end 112 of sleeve body 11, and in the positioning jack 14 dearly insert structure floor 13 offered.The bore position of positioning jack 14 can be arranged according to the position of the hole to be provided in practice of construction, positioning jack 14 is made to be positioned at the center of hole to be provided, and positioning jack 14 closely retrains with the positioning end of positioning bar 12, to avoid presetly in floor concrete casting vibrates process staying the integral shift of sleeve 10 and the skew of bottom, ensure that the positioning precision that hole to be provided is constructed, thus decrease the later stage because hole to be provided offsets the problem of the Pipe installing inconvenience caused, and extra rectification construction caused thus is born and trimming cost.
Further, the inner side barrel of the second end 112 of sleeve body 11 is welded with brace rod 122, and positioning bar 12 welds mutually with brace rod 122, plays the effect of stop sleeve body 11 and reinforcing positioning bar 12.
Threading of the present utility model preset sleeve 10 reusable edible, structure are simple, adopt the mode that positioning bar 12 is set in the inside of sleeve body 11, sleeve body 11 is positioned the hole to be provided position of structure floor 13, traditional employing baked wheaten cake silk is replaced to carry out the mode of colligation fixed muffle and floor, both the operation of the Embedment Construction of sleeve body 11 had been simplified, the time shortening the hole to be provided construction of structure floor 13 of high degree, can also ensure shaping after the hole wall of floor slab preformed hole smooth clean and tidy, there is no a mao defect.
Further as better embodiment of the present utility model, be provided with handle 15 at the first end 111 of sleeve body 11, so that go out sleeve body 11, convenient operation by handle 15 from the floorslab concrete endosome of initial set.Further, this handle 15 is welded in the handle reinforcing bar of the inner side barrel of the first end 111 of sleeve body 11 for two ends, gather materials on the spot, structure is simple, easy construction, inner side barrel handle 15 being welded on sleeve body 11 can keep the planeness of sleeve body 11 outer wall, improves the smooth fineness of shaping rear hole to be provided.
The preset sleeve 10 of threading of the present utility model in use, first makes sleeve body 11, makes sleeve body 11 be designed to up big and down small form of structure; Then, dowel 121 is utilized to be welded and fixed the positioning bar 12 of Φ 18mm in the center of sleeve body 11; After treating stay in place formwork 13, reinforcement engineering construction, in the indwelling position of correct preset sleeve 10, electricity consumption is drilled on stay in place formwork 13 and bores the positioning jack 14 that a diameter is 18mm, the positioning bar 12 at sleeve body 11 center of hole to be provided is firmly inserted in positioning jack 14, gets final product fixation; Then, at the outside fluid concrete of sleeve body 11, when treating concrete initial set, the handle 15 of sleeve body 11 upper end 111 is utilized to extract sleeve body 11, concrete after solidifying just leave for wearing the hole to be provided of pipeline, Stability Analysis of Structures, easy accessibility and the positioning precision of hole to be provided is high.
Below by reference to the accompanying drawings and embodiment the utility model has been described in detail, those skilled in the art can make many variations example to the utility model according to the above description.Thus, some details in embodiment should not formed restriction of the present utility model, the utility model by the scope that defines using appended claims as protection domain of the present utility model.
