Abstract
The invention provides a pile toe formwork fixing process. The pile toe formwork fixing process comprises the following operating steps of 1, making four supports the same in length from square steel; 2, bending the position, 45mm away from each end, of each support into a 135-degree angle; 3, machining a hole with the diameter being 20mm in the position, 25mm away from each end, of each support, wherein each hole can allow an M16 bolt to pass through smoothly; 4, welding three of the supports to the lower portion, the left side and the right side of a pile toe formwork correspondingly, and welding the remaining support to the upper portion of the pile toe formwork; and 5, fixedly fastening the four supports with the M16 bolts, wherein the specification of the square steel is 30mm*30mm*2.5mm, and the pile toe formwork is located in the center of the four supports. According to the pile toe formwork fixing process, the pile toe formwork is fixed to the middle of a square frame spliced by the square steel and the bolts; support rigidity is enhanced; and the problems that support force is insufficient, the formwork is loosened, and the contact face between a pile toe and a pile body is not tight, so that slurry leakage and slab staggering are caused are solved.
Description
Technical field
The invention belongs to building field, more particularly, to a kind of pile top template technique for fixing.
Background technology
Precast prestressed square pile pile top prefabricated using rear formwork casting craft, traditional pile top formwork support process includes mould
Plate is fixing and support top two parts, template technique for fixing by means of the round steel cuff of a diameter of 20mm of HPB300,
By the timber wedge extruding of four direction, traditional handicraft tedious process, the auxiliary material of employing is more, takes longer
Work quality is difficult to ensure that, round steel cuff is yielding, and timber wedge is fragile, and template is easy with the contact position of timber wedge
Slip, component easily occurs running the Appearance quality defects such as mould, spillage, and bottom adopts flitch supporting process, steadiness
Poor, work progress easily causes pile top skewness, timber wedge often reaches pile top surface, to pile top
Obstacle is caused in surface receipts face, faulting of slab ends or pitted skin easily, more using timber wedge, easily causes live debris
Many, dirty and messy disorder phenomenon, template steadiness is poor, and personnel of vibrating dare not be vibrated, and easily causes leakage is shaken, bubble etc.
Problem, affects pile top density.
Content of the invention
The present invention is exactly directed to above technical problem, provides a kind of pile top template technique for fixing.
The present invention for achieving the above object, employs the following technical solutions：Pile top template technique for fixing, including following
Operating procedure：
(1), square steel is done four isometric supports；
(2), each support is bent into 135 ° of angles at the 45mm of termination；
(3), each support turns the hole of an a diameter of 20mm, this Kong Nengrang M16 at the 25mm of termination
Bolt pass through；
(4), three supports are respectively welded at below pile top template, the left side and the right side, a root bead is connected on stake
Above sharp template；
(5), four supports are fixed tight with the bolt of M16.
The specification of described square steel is 30mm × 30mm × 2.5mm.
Described pile top template is in the center of four supports.
Compared with prior art, the invention has the beneficial effects as follows：
(1), the square bearer that the reinforcing bar cuff improvement of a diameter of for HPB235 20mm is spliced into by square steel bolt,
Increased the rigidity of support, solve that support force is not enough, template loosens, pile top and pile body contact surface imprecision,
Produce the problem of spillage faulting of slab ends；
(2), support and template are welded together, improve template and the rigidity of pile body overall connection, keep away
The problem having exempted to form sand line due to some areas laminating spillage closely not caused in casting process；
(3), the extrusion process of timber wedge is improved square steel bolt tight technique, enhance the adjustability that template fixes
With steadiness it is therefore prevented that because the timber wedge of generation of vibrating loosens, spillage runs the problem of mould in work progress.
Brief description
Fig. 1 is the structural representation of the present invention；
In figure：1st, support；2nd, bolt；3rd, pile top template.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As illustrated, pile top template technique for fixing, including following operating procedure：
(1), square steel is done four isometric supports 1；
(2), each support 1 is bent into 135 ° of angles at the 45mm of termination；
(3), each support 1 turns the hole of an a diameter of 20mm, this Kong Nengrang M16 at the 25mm of termination
Bolt 2 pass through；
(4), three supports 1 are respectively welded at below pile top template 3, the left side and the right side, a root bead connects
Above pile top template 3；
(5), four supports 1 are used the bolt 2 of M16 fixing tight.
The specification of described square steel is 30mm × 30mm × 2.5mm.
Described pile top template 3 is in the center of four supports 1.
Pile top template of the present invention is fixed on the centre position of the square bearer being spliced into by square steel bolt 2, increased and props up
The rigidity of support, solves that support force is not enough, and template loosens, pile top and pile body contact surface imprecision, produces spillage
The problem of faulting of slab ends.
Above in conjunction with accompanying drawing, the present invention is exemplarily described it is clear that the present invention implement be not subject to above-mentioned
The restriction of mode, as long as employing the various improvement that method of the present invention design and technical scheme are carried out, or without
Improve and directly apply to other occasions, all within protection scope of the present invention.
