Abstract
The utility model discloses a kind of pre-embedded bolt, the pre-buried prefabricated piping lanes for hanging nail, including prefabricated piping lane ontology (1), it is provided on the top plate of the prefabricated piping lane ontology (1) and pre-buried hangs nail (2), and it is provided with short slot (1a) at every pre-buried position for hanging nail (2), so that the pre-buried T-shape end for hanging nail (2) just it is exposed outside, and the pre-buried top surface for hanging nail (2) is just flushed with the top surface of prefabricated piping lane ontology (1)；It is respectively arranged with pre-embedded bolt (3) in the left and right sidewall of the prefabricated piping lane ontology (1).The pre-buried nail that hangs can reduce the damage transported up and down to structure in transportational process, and bolt deviation can be prevented using set shaped steel formwork pre-embedded bolt, avoid squeezing into and be bolted phenomena such as mounting bracket generates destruction to structure, infiltration, leak occurs.
Description
Technical field
The utility model is related to the piping lane technical fields of Urban Buried Pipeline Network Systems, and in particular to a kind of pre-embedded bolt, pre-
Bury the prefabricated piping lane for hanging nail.
Background technology
Piping lane refers to the municipal public use tunnel built below urban road, by electric power, communication, water supply, combustion gas etc.
A variety of municipal pipelines concentrate in together, and " unified planning, unified construction, unified management " are carried out, to accomplish the synthesis of the underground space
Using shared with resource.
Piping lane uses armored concrete pouring molding, therefore also becomes " prefabricated piping lane ".Now currently, prefabricated piping lane is by steel
Muscle, concreting form, and lack the installation of built-in fitting.First, after the completion of later stage assembly, by mounting bracket in piping lane
When laying a variety of municipal pipelines such as electric power, communication, water supply, combustion gas, needs to squeeze into bolt on piping lane, be easily destroyed piping lane knot
Structure increases piping lane infiltration risk.In addition, being hung again using the binding of fabric bandage in transportational process above and below prefabricated piping lane
Dress is easy to generate damage to structure.
Utility model content
The utility model is intended to provide a kind of prefabricated piping lane for facilitating lifting and connecting mounting bracket, avoids beating on piping lane
Enter bolt and destroy Pipe rack and cause to seep water, and transport does not need fabric bandage and ties up and lifted.
For this purpose, technical solution used by the utility model is：A kind of pre-embedded bolt, the pre-buried prefabricated piping lane for hanging nail, in advance
Bolt, the pre-buried prefabricated piping lane for hanging nail, including prefabricated piping lane ontology are buried, is provided on the top plate of the prefabricated piping lane ontology pre-buried
Hang nail, and short slot be provided at every pre-buried position for hanging nail so that the pre-buried T-shape end for hanging nail just it is exposed outside,
And the pre-buried top surface for hanging nail is just flushed with the top surface of prefabricated piping lane ontology；In the left and right sidewall of the prefabricated piping lane ontology respectively
It is provided with pre-embedded bolt.
The short slot is hemispherical as a preferred embodiment of the above solution, and hemispherical rubber is equipped in hemispheric short slot,
When prefabricated piping lane ontology pouring molding, hemispherical rubber just covers the pre-buried T-shape end for hanging nail, when removing hemispherical rubber
After glue, the pre-buried T-shape end ability for hanging nail is exposed outside.The pre-buried T-shape end for hanging nail is covered by presetting hemispherical rubber
Firmly, it is ensured that casting concrete will not enter the space of hemispherical short slot, and when form removal again removes hemispherical rubber, make pre-buried to hang nail
T-shape end it is exposed outside, facilitate suspender to enter hemispherical short slot and clamp T-shape end and lift.
Further, pre-buried hang follows closely totally four, and in rectangular layout, ensures that lifting is steady, avoids going out in hoisting process
Existing beat.
The utility model has the beneficial effects that：Before prefabricated piping lane concreting, on the top plate of prefabricated piping lane ontology
Pre-buried hemispherical rubber and pre-buried hang nail；After the completion of steel form molds, pre-embedded bolt is put into the reserved hole position of steel form
It sets, tightening nuts, then casting concrete.After the completion of pouring, after removing hemispherical rubber, the pre-buried T-shape end for hanging nail is exposed
Outside, facilitate suspender to enter hemispherical short slot and clamp T-shape end to lift.The pre-buried nail that hangs can reduce transportational process
In the damage transported up and down to structure, can prevent bolt deviation using set shaped steel formwork pre-embedded bolt, avoid squeezing into bolt
Connect phenomena such as mounting bracket generates destruction to structure, infiltration, leak occurs.
Description of the drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A sectional views of Fig. 1.
Fig. 4 is the state that default hemispherical rubber covers the pre-buried T-shape end for hanging nail.
Specific implementation mode
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail：
In conjunction with shown in Fig. 1-Fig. 4, a kind of pre-embedded bolt, the pre-buried prefabricated piping lane for hanging nail, mainly by prefabricated piping lane ontology 1,
Pre-buried nail 2, pre-embedded bolt 3, the hemispherical rubber 4 of hanging forms.
The pre-buried nail 2 that hangs is arranged on the top plate of prefabricated piping lane ontology 1.It is pre-buried at every on the top plate of prefabricated piping lane ontology 1
Hang nail 2 position at be provided with short slot 1a so that it is pre-buried hang nail 2 T-shape end just it is exposed outside, it is pre-buried hang nail 2 top
Face is just flushed with the top surface of prefabricated piping lane ontology 1.It is respectively arranged with pre-embedded bolt 3 in the left and right sidewall of prefabricated piping lane ontology 1,
A variety of municipal pipelines such as electric power, communication, water supply, combustion gas are laid for connecting mounting bracket.
Preferably, short slot 1a is hemispherical, and hemispherical rubber 4, prefabricated piping lane sheet are equipped in hemispheric short slot 1a
When 1 pouring molding of body, hemispherical rubber 4 just covers the pre-buried T-shape end for hanging nail 2.After removing hemispherical rubber 4,
The pre-buried T-shape end ability for hanging nail 2 is exposed outside.
Preferably, pre-buried to hang nail 2 totally four and in rectangular layout, but it is not limited to four.
The method for prefabricating of above-mentioned prefabricated piping lane, step are：
(a) steel bar meter is bound；
(b) steel form and formwork are made；
(c) concreting；
(d) it conserves；
(e) form removal.The above, identical as traditional method for prefabricating of prefabricated piping lane, details are not described herein, and difference exists
In：
In step (b), several bolt through-holes are reserved on steel form, pre-embedded bolt 3 passes through corresponding on steel form
Bolt through-hole simultaneously tighten by support screw cap；Hemispherical rubber 4 is sleeved on corresponding pre-buried T-shape end for hanging nail 2, then solid
It is scheduled on concreting mold.
In step (e), form removal is carried out after nut corresponding with pre-embedded bolt 3 on steel form is unscrewed, after the completion of form removal,
Hemispherical rubber 4 is removed, keeps the pre-buried T-shape end for hanging nail 2 exposed outside.
