Description
Technical field
The present invention relates to prefabricated components engineering equipment field is installed in assembled architecture, in particularly a kind of assembled architecture
Concrete component supporting adn fixing device and using method.
Background technology
In assembled architecture, precast concrete column, beam, plate are required to after supporting supporting ＆ stablizing, are connected using engineering site
Connect, fix, welding, the secondary mode for pouring junction belt is combined and is mounted together, each layer of structure is required in next layer
Carry out the assembling construction of this layer in the case of installing.
Existing support fixed structure typically reinforces prefabricated components by the way of expansion bolt fixes support bar at present.
Concretely comprise the following steps prefabricated metope drill → dispose expansion bolt → fixed iron piece → fixation support bar → ground beat anchor bolt →
Ground fixed iron piece → fixation support bar.This mode has several drawbacks, first, using common expansion bolt, swollen after screwing
Swollen outside expansion, without external force in the case of be difficult restore to the original state, in most cases the expansion bolt after use can not be secondary
Use, after cutting away exposed portion, the big portion of bolt is stored in prefabricated components great majority, to later stage metope, floor treatment band
To bother, while waste of materials；Second, having had more the operation of drilling together, because the non-telescoping property of support bar, drilling is determined
Position usually consumes certain man-hour；Third, general expansion bolt, the outer connection design that end does not optimize, most cases
Connection iron plate is pushed down by nut down to fix support bar；Fourth, support bar does not have the design that can adjust length, angle, purposes
Single, it is impossible to a large amount of prefabricated components for adapting to all size model, it is impossible to fine setting, correction after fixed installation；Fifth, support bar
Can only one end be fixed on facade structures, one end and be fixed on earth construction, lack the design that fixed, multi-angle is fixed in flakes, lack
Combination extends, and majority is fixed on ground, increased the man-hour of surface drilling；Sixth, support bar does not have standardized production, it is impossible to just
It is applied in combination the measurer that support bar is installed as structure promptly, reduces the work of repeatability；Seventh, after support bar is installed, it is impossible to
Easily easily dismounting, displacement, can only unclamp fixing nut dismounting, and work inconvenience；Eighth, being installed on the oblique of ground
Support bar affect other follow-up works, be not easy to mechanization Ground Operation；Ninth, expansion bolt effectively cannot be fixed containing guarantor
The precast wall body of warm interlayer.
Therefore, using a kind of easy construction, save material, safety and firmness, low cost, efficiency high, of many uses and easy more
The prefabricated components supporting adn fixing device of the features such as changing is necessary.
Content of the invention

Fixed, loosen flap sleeve pipe by reversely screwing swollen plug under anchorage screw release when disassembly is desired, you can be dismantled；Logical
The structure is crossed, makes the present invention more easy to assemble, while, it is to avoid expansion anchoring bolt is residued in prefabricated components, has not only saved material
Material, and make later stage metope, floor treatment convenient.The anchoring bolt of present invention expansion simultaneously does not result in destruction in dismounting,
It is thus able to reuse, further saves material.The expansion anchoring bolt of the present invention holds out against pre-manufactured hole using flap sleeve pipe, because
The surface area of flap sleeve pipe is larger, when pre-manufactured hole is held out against, pre-manufactured hole hole wall uniform force, safety and firmness, also therefore, it is possible to
In the precast wall body containing heat preservation sandwich layer.
3) combined support bar structure of the invention is：Outer tube is cased with outside inner sleeve, and securing member is set on outer tube；Make
Used time, according to construction demand, outer tube is connected another inner sleeve, after outer tube and inner sleeve are fastened through securing member, with
Reach preset length；By the structure, each combined support bar can realize standardized production, in use, only need to accordingly
The combined support bar of quantity is assembled to preset length, thus flexible and convenient to use.Due to standardized production, effectively can reduce
Manufacturing cost, improving production efficiency.Meanwhile, after combined support bar is installed, can easily dismantle, shift, jackscrew need only be unclamped and torn open
Unload, convenient and swift.In addition, when combined support bar is installed, can whole hanging composite reinforcements, facilitate mechanization ground to make
Industry, further makes construction convenient.
4) present invention is connected with retainer ring by connection buckle, and the attachment structure has the very big free degree；By the structure,
The angle of combined support bar connection can be made arbitrarily to adjust, thus make the purposes of the present invention more extensively (as shown in Figure 1-2).This
Bright be divided into expansion anchoring bolt, three construction modules of adjustable fixator and combined support bar；By the modular structure, change more
Facilitate, also more reduces cost.
