Description
Technical field
The utility model relates to building template scaffold field, in particular to a kind of drawknot pre-embedded bolt.
Background technique
Concrete wall needs to constrain the structure of wall or beam using template before pouring, mainly using between template
The thickness of distance limitation wall or beam.In order to keep the distance between template constant, screw rod fixed form through walls is generally used.It is leaning on
The corner of nearly floor, the method for traditional fixed form are the placement cement items between two pieces of vertical formworks, then with iron wire or
Person's tie-rod fixes outboard template, i.e. cement item and iron wire (or screw rod) collective effect carrys out the distance between fixed form.With
The development of technology, and occur some using more convenient, function more fully drawknot pre-embedded bolt.
Utility model patent if Authorization Notice No. is CN206457939U discloses a kind of multi-functional drawknot pre-embedded bolt,
The multi-functional drawknot pre-embedded bolt is positioned without using cement item, can also be achieved the functions such as hanging steel rope, fastener for installing.But
It is that in casting concrete and after removing template, the nut that is located by connecting is embedded in concrete (concrete), and the bottom surface of right angle component is exposed
Concrete (concrete) outside, and the nail of fixed pre-embedded bolt can be stuck in right angle component.Spiral shell and female right angle component be located by connecting not
It can recycle, loss is more, increases cost.Nail is not easy to remove, and right angle component and nail (usually irony) Yi Sheng
Rust, this can all influence subsequent finishing.
Summary of the invention
The purpose of this utility model is to provide a kind of drawknot pre-embedded bolts, with the structure of the existing pre-embedded bolt of simplification, side
Just use and save cost.
The utility model uses following technical scheme:
A kind of drawknot pre-embedded bolt, including bolt, abutment sleeve and fixation member, it is characterised in that: fixation member includes
First plane, the second plane and cambered surface, the first plane are equipped with tapped blind hole, and cambered surface is equipped with fixation hole；One end of bolt with
Tapped blind hole connection in fixation member；Abutment sleeve is set on bolt.Fixation hole in fixation member cambered surface is through-hole, from
Cambered surface is penetrated to the second plane.When in use, the second plane of fixation member is contacted with top template, cambered surface upward, the first plane
Concordant with the edge of top template, hammering into nail from fixation hole connect fixation member with top template.Abutment sleeve is placed in side form
Between plate and fixation member, to limit side template at a distance from the first plane of fixing piece.First plane direction of fixation member
Side template, side template are equipped with the hole passed through for bolt；One end of bolt penetrates from the hole of side template and passes through abutment sleeve,
It is inserted into the tapped blind hole of fixing piece, is connected through a screw thread bolt with tapped blind hole；The other end of bolt is exposed at outside side template
Side can be used for connecting the other components such as fastening nut.In casting concrete, after concrete setting, first bolt can be removed, then
Dismantle top template；Because fixation member includes cambered surface, the binding force of cambered surface and concrete is very weak, and the combination of nail and top template
Power is stronger, so fixation member can be removed together with top template, to complete the disassembly of bolt and fixation member.
Further, the cambered surface edge of the fixation member is equipped with gap, and the fixation hole is arranged on gap.If
Setting gap is to tap nail using tool (such as hammer) for convenience, to be easier to hammer into nail.
Further, the quantity of the gap is three, and a fixation hole is arranged on each gap.
Further, the abutment sleeve is the sleeve of plastic material.
Further, described bolt one end has flat structure, square structure or hexagonal structure.It is flat structure, rectangular
Structure or hexagonal structure are for cooperating extracting tool (such as electric wrench), so as to fast quick-detach.
Further, the bolt and fixation member are all made of metal and are made.Preferably, the bolt and fixed part
Part is all made of steel and is made.
The utility model has the beneficial effects that bolt and fixation member can be removed after use, can be recycled,
It is good for the environment and saves cost.The utility model structure is simple, and it is convenient to dismount, and is easy to use.

Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
As shown in Fig. 1~5, a kind of drawknot pre-embedded bolt of the utility model, by bolt 1, abutment sleeve 2 and fixation member
3 compositions.Wherein, fixation member 3 includes the first plane 301, the second plane 302 and cambered surface 303, and the first plane 301 and second is flat
Face 302 is mutually perpendicular to, and cambered surface 303 intersects with the first plane 301, the second plane 302 respectively；In the first plane of fixation member 3
On 301, tapped blind hole 304 is inwardly offered perpendicular to the first plane 301, tapped blind hole 304 does not penetrate, and tapped blind hole 304
Match with bolt 1；In the cambered surface 303 of fixation member 3, open up close to the edge of the second plane 302 there are three gap 306,
Fixation hole 305 is opened up in gap 306 respectively, fixation hole 305 is penetrated to the second plane 302.Two end surfaces of bolt 1 are equipped with spiral shell
Line 101, screw thread 101 and the tapped blind hole 304 of fixation member 3 match.
Bolt 1 and fixation member 3 are all made of steel and are made；One end of bolt 1 is equipped with flat structure 102.Abutment sleeve 2 is
Tubular construction is adopted made of plastic.
As shown in fig. 6, state in use drawknot pre-embedded bolt when, the second plane 302 and the top template 4 of fixation member 3
Contact, the first plane 301 of fixation member 3 is concordant with beam inner side template 5, and three that nail is hammered into fixation member 3 respectively are solid
Determine to be fixed on fixation member 3 on top template 4.Abutment sleeve 2 is the side form in restraint beam outboard template 7 and beam
The distance between plate 5, the length of abutment sleeve 2 is equal to the distance between beam outboard template 7 and beam inner side template 5；Positioning sleeve
2 one end of cylinder resist the first plane 301 of fixation member 3, and the other end resists beam outboard template 7.Confession is offered on beam outboard template 7
The one end in the hole that bolt 1 passes through, bolt 1 is penetrated from the hole of beam outboard template 7, is then passed through abutment sleeve 2, and be inserted into fixation
