Description

A kind of Precast T-Beam end head formwork
Technical field
This utility model relates to a kind of Precast T-Beam end head formwork, belongs to mould applications for building.
Background technology
Precast T-Beam is pre-constructed unit conventional on bridge, its have construction period fast, The features such as span is big, bearing capacity is big, are widely used in highway bridge and Urban Bridge Construction In.But during traditional T is beam prefabricated, three formwork erections of sealing off and covering anchorage concrete pour, This Normal practice defect is obvious, and model sheetinstallat piece is many, the easy spillage of concrete, end Easily there is voids and pits, bubble, falls the phenomenons such as limit in head concrete surface;Two-step pouring is mixed The contact surface of solidifying soil easily occurs that contraction fissure, termination are connected the most smoother with beam body, linearly The most smooth, presentation quality is poor, uneconomical the most not environmentally.
T-shaped beam (T axing lying) T-shaped beam refers to that cross-sectional form is T The beam of type, T-shaped beam both sides choose part be referred to as the edge of a wing, intermediate portion is referred to as beam rib, T-shaped Beam section compressive region utilizes pressure concrete make flange plate and double as bridge floor;Tensile region steel Muscle or deformed bar bear pulling force, and CONCRETE T-BEAMS bridge has simple in construction, stress Clearly, save material, set up easy for installation, the advantages such as span ability is bigger, be widely used in me In state's highway construction, bridge construction, usage amount is big.
Prefabricated every tee girder plate process is: bed die installation, reinforcing bar binding, installation form (side form and end mould), casting concrete, concrete curing, form removal, steel strand, Preparation before preparation before stretch-draw, mud jacking, mud jacking, end-blocking, end-blocking, the beauty treatment of beam body profile, Beam is winched to finished product district by beam after having produced.
But these Precast T-Beam end head formworks the most existing are due to prefabricated every tee girder The end mould that plate uses is three formwork erections before next procedure end-blocking concreting, model sheetinstallat Piece is many, the easy spillage of concrete, termination concrete surface easily occur voids and pits, bubble, Fall the phenomenons such as limit;Easily there is contraction fissure, termination and beam in the contact surface of two-step pouring concrete Body linking is the most smoother, and the most smooth, presentation quality is poor, and this had both produced substantial amounts of building rubbish Rubbish, increases again manufacturing cost.
Summary of the invention
The deficiency existed for above-mentioned prior art, the purpose of this utility model is intended to overcome now The shortcoming having technology, it is provided that a kind of simple to operate, low cost of manufacture, can realize improving construction Efficiency and overcome beam slab termination piece to be connected the prefabricated T of one of the problem such as the most smoother with beam body Beam end head formwork.
For achieving the above object, this utility model one Precast T-Beam end head formwork be by under Array structure completes: a kind of Precast T-Beam end head formwork, by Precast T-Beam end head formwork originally Body (1), prestressed stretch-draw pipeline (2), novel die (3) and embedded bar (4) Constituting, the described overall structure in T shape of Precast T-Beam end head formwork body (1), in institute The lengthwise position of Precast T-Beam end head formwork body (1) stated is provided with novel die (3), Prestressed stretch-draw pipeline (2) and circular hole (5) it is respectively arranged with in described novel die (3), The embedded bar (4) matched with it it is provided with on described circular hole (5).
Preferably, two Side Templates of described Precast T-Beam end head formwork body (1) are longitudinally Lengthen, and extension length is end-blocking concrete thickness, described prestressed stretch-draw pipeline (2) It is arranged on the middle part of described novel die (3), and it is the most identical to be set to shape and structure Three.
Preferably, described novel die (3) is processed in concave groove type structure, and in recessed Circular hole (5), described circular hole (5) it is provided with on the both sides of the novel die (3) of trench structure Position be embedded with the embedded bar (4) of the long Ф of six roots of sensation 30cm 12, and described embedded bar (4) Protruded length be 15cm, fix for follow-up sealing off and covering anchorage concrete blinding or sealing off and covering anchorage be installed Concrete blinding (6).
Preferably, the diameter of described circular hole (5) is set to Ф 14, and it is equal to be set to size Identical six, described sealing off and covering anchorage concrete blinding (6) is end-blocking mounted split pattern.
Operation principle is: this utility model more specifically embodiment be use and manufacture this one Planting Precast T-Beam end head formwork to comprise the following steps that, first at T beam two ends side mold portion The vertical punching block in both sides, T beam duct is original design along longitudinally lengthening 20cm, the 20cm of this lengthening Sealing off and covering anchorage concrete thickness;Second is that the novel die (3) of T beam two ends end mould part is made Concave groove type, groove size is 40cm × 165 × 20cm, and recessed at novel die (3) Grooved position arranges the circular hole (5) of six Ф 14;3rd is that T beam steel bar colligation completes After, these six circular hole (5) positions pre-buried six roots of sensation 30cm long Ф 12 embedded bar (4), Fix for follow-up sealing off and covering anchorage concrete blinding (6);4th is end-blocking template construct, end-blocking Template uses 1cm thickness punching block, a size of 0.5m × 2m, reserved six Ф on novel die 14 circular holes (5), position is consistent with T beam-ends head embedded bar (4);Finally seal Side Template is installed, i.e. template passes embedded bar (4), uses Φ 12 embedded bar (4) Laterally weld with embedded bar (4), finally can complete work with wood contract by fixing for template Make.
This utility model compared with prior art produced by provide the benefit that: this utility model By novel die is processed in concave groove type structure, and at the novel die in concave groove type structure Both sides on be provided with circular hole, the position of circular hole is embedded with the pre-buried steel of the long Ф of six roots of sensation 30cm 12 Muscle, and the protruded length of described embedded bar is 15cm, therefore, adopts this method and makes T Beam-ends head bottom and both sides concrete are disposably and beam body pours molding, improve the entirety of beam body Property, use concave groove type and single side template to replace original three face die plates simultaneously, save mould Plate, Simplified flowsheet, do not produce building waste, energy-conserving and environment-protective, cost is low, it is ensured that mixed The pouring quality of solidifying soil, can overcome that T beam novel die piece is many, globality is strong, easily The problems such as spillage, it is simple to operate, improves efficiency of construction.
