Description
Technical field
The utility model relates to building engineering fields, and in particular to a kind of centering type is to tensing fixing bolt external member.
Background technique
Building template is a kind of temporary supporting structure, makes by design requirement, makes concrete structure, component by defined
Position, geometric dimension forming, keep its correct position, and bear the external loads of building template self weight and effect on it.Into
The purpose of row form work engineering is to guarantee concrete engineering quality and construction safety, accelerate construction progress and reduce engineering cost.It is existing
The working architectural template structure of pouring concrete Structural Engineering is mainly made of panel, support construction and connector three parts.Face
Plate is the force bearing plate of direct contact newly-laid concrete；Support construction is then the interim knot of supporting faceplate, concrete and construction loads
Structure, guarantee architectural template structure combine securely, accomplish it is indeformable, do not destroy；Connector is to connect panel with support construction
Integral accessory.
It is often related in the vertical template system of cast-in-place concrete structure to the end head formwork of wall be fastenedly connected, end mould
The reinforcing reliability and precision of plate directly influence the Forming Quality of concrete structure wall.Existing wall end head formwork it is tight
Gu mode be will lead it is stupefied be connected by right-angle coupler with the back cord of wall side form, the connection type reliability is low, and fastener connection is anti-
Sliding ability is low, causes in concreting process, and concrete easily causes swollen mould even quick-fried the lateral pressure of end head formwork
The case where mould.And existing fastener connection type is not flexible and adjustment accurate in terms of wall end head formwork verticality adjustment
Degree is not high, time-consuming.
Utility model content
The purpose of this utility model is to provide a kind of centering types to fixing bolt external member is tensed, to solve to mix in the prior art
In solidifying soil cast-in-place structural wall end head formwork be fastenedly connected and accurate adjustment control in terms of defect, realize that template system fastens
It is safe and reliable, accurate size is adjustable, purpose convenient for disassembly and assembly.
The utility model is achieved through the following technical solutions:
A kind of centering type is arranged chevron fastener, tight to fixing bolt external member, including split bolt is tensed on the split bolt
Firmware and two nuts, two nuts are located at side of the chevron fastener far from fastener, fastener far from chevron fastener
Side, circular arc bayonet, through-hole are set on the fastener, and the circular arc bayonet is used to block the back cord of wall side form, described
Split bolt is passed through from through-hole.
For wall end head formwork in the prior art fastening means will lead it is stupefied by right-angle coupler and wall side form
The problem of back cord is connected, and the connection type reliability is low, and fastener connects low resistant slide ability, inconvenient adjusting, the utility model mentions
A kind of centering type is to fixing bolt external member is tensed out, and wherein master of the chevron fastener for blocking wall end head formwork is stupefied, and fastener is logical
It crosses circular arc bayonet and blocks any one back cord on wall side form, then the through-hole by split bolt on chevron fastener, fastener,
The nut of two sides is tightened again, realizes the reinforcing to the end head formwork and side form of wall.In concreting process, concrete pair
The lateral pressure of end head formwork be transferred to it is main it is stupefied on, since chevron fastener and fastener are limited by the nut of two sides, chevron
Fastener can not be displaced outwardly so that main stupefied, end head formwork can not distending, avoid swollen mould even quick-fried mould the case where go out
It is existing.When needing to adjust the verticality of end head formwork, it is only necessary to the nut close to chevron fastener is adjusted, so that the nut is to drawing spiral shell
It is moved on bolt, the adjusting within the scope of a screw pitch can be realized, realize the accurate adjusting to end mold plate verticality；This reality
Dismounting can be realized by manpower completely with novel, significantly improve the disassembly efficiency of template system.
The through-hole is slotted hole.So that even if Screw arbor with nut at both-ends non-face through-hole, is also capable of in the slave through-hole of relative tilt
It passes through, so that the use scope of the utility model is wider, does not locate even if the master of end head formwork is stupefied with the back cord of corresponding side form
It in identical height level, can also be reinforced by the utility model, to greatly improve being applicable in for the utility model
Range.
The extended line of the long axis of the slotted hole without circular arc bayonet the center of circle.It is circular arc bayonet compared to slotted hole
Long eccentric shaft.
Preferably, the internal diameter of the circular arc bayonet is equal with the outer diameter of split bolt.Ensure between circular arc bayonet and back cord
With enough frictional resistance, it is ensured that fastener can be stable is mounted on back cord.
Preferably, the nut is castle nut.Convenient for manpower hand operation, disassembly efficiency is improved.
The utility model compared with prior art, has the following advantages and benefits:
A kind of centering type of the utility model to tense fixing bolt external member, avoid swollen mould even quick-fried mould the case where appearance；
It only needs to adjust the adjusting that can be realized close to the nut of chevron fastener within the scope of a screw pitch, realize to end mold plate verticality
It is accurate to adjust；The utility model passes through manpower completely can be realized dismounting, significantly improve the disassembly efficiency of template system.
