Description
Technical field:
The present invention relates to technical field of bridge construction, specifically a kind of Precast T-Beam floor reinforcing bar, prestress pipe are fixed draw and insert-type and are installed mould bases, are applicable to the installation of Precast T-Beam floor reinforcing bar and prestress pipe.
Background technology:
Prestressed reinforced concrete T beam because of have bearing capacity high, be applicable to the advantages such as the strong and construction technology of various span bridge, shock resistance is relatively simple and extensive use in Bridges in Our Country design.In construction, in the construction of particularly Long span T beam, because T beam floor framework of steel reinforcement is long, high, narrow, direct colligation on pedestal, the very difficult controls such as the straight degree of framework of steel reinforcement, the spacing of reinforcing bar.Stressed, the durability of accuracy on beam of the straight degree of T beam reinforcement cages, bar spacing, protective layer thickness, particularly prestress pipe location affect very large.Given this, under construction standardization, the background that becomes more meticulous, T beam floor reinforcing bar, prestress pipe are installed and are adopted that to install mould bases imperative.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide a kind of fixed, disposable complete after recycle, until T beam of the same type is constructed complete T beam floor reinforcing bar, prestress pipe install mould bases.This installs mould bases and can locate prestress pipe fast, accurately in construction, coordinates circular high-strength mortar cushion block, T beam floor thickness of protection tier fraction can be made all to reach more than 98%.
The die-filling frame of intrinsic safety designs especially for the installation of T beam floor reinforcing bar, prestress pipe, have safe, efficient, easy to operate, improve feature, particularly Long span, the deck-molding T beam more than more than 2 meters such as quality, advantage is more obvious.
Technical solution problem of the present invention adopts following technical scheme:
Precast T-Beam floor reinforcing bar, prestress pipe are fixed draw and insert-type and are installed mould bases, and it comprises:
Be fixedly installed on the fixing bed die frame on concrete bed, described fixing bed die frame is made up of horizontally disposed two parallel longitudinal ribs and the spaced many cross ribs be connected laterally between two longitudinal ribs, on each described longitudinal rib, interval is equidistantly provided with longitudinal rib stopper slot along its length, equally, on each described cross rib, interval is equidistantly provided with cross rib stopper slot along its length;
The sidepiece of a described longitudinal rib is installed with multiple vertical main mould bases wherein, the length direction of multiple vertical main mould bases longitudinally rib is equidistantly intervally arranged, each described vertical main mould bases is connected in connecting rod between two vertical ribs by two vertical ribs vertically arranged and transverse direction and forms, and the length direction of described connecting rod is parallel with the length direction of described cross rib;
Two vertical ribs of each described vertical main mould bases are provided with the through hole that multiple level is offered from top to bottom, the draw and insert-type horizontal bar arranging " E " font installs mould bases, and three horizontal bars being up and down parallel to the horizontal bar installation mould bases of described cross rib are inserted in the through hole of described vertical rib;
Be installed with horizontal ribs at the top of the vertical rib of a row of the close longitudinal rib of multiple vertical main mould bases, the length direction of described horizontal ribs is parallel with the length direction of described longitudinal rib, and in described horizontal ribs, interval is equidistantly provided with horizontal ribs stopper slot along its length; Described horizontal ribs stopper slot is corresponding with described longitudinal rib stopper slot in the vertical direction position;
Operating platform is installed with in the outside portion of the vertical rib of a row away from longitudinal rib of multiple vertical main mould bases.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention installs mould bases while having the straight degree of guarantee T beam floor framework of steel reinforcement, bar spacing, prestress pipe accurate positioning, also has:
The present invention greatly reduces the safety factor in skeleton process of binding.Fixed installation mould bases effectively ensure that the monolithic stability in tie with reinforcing bar process, has stopped because strong wind, unexpected push-and-pull cause the risk of toppling.Fixing operating platform, had both had the effect ensureing to install mould bases rigidity, in turn ensure that safety during operator's ascend operation;
Recycle after this installation mould bases disposal molding, utilization pulls and pushes principle, horizontal bar is installed after mould bases inserts and can be located vertical equity muscle, extract aftershaping framework of steel reinforcement out and mould bases is installed and can depart from completely, overcome installation mould bases in the past and repeatedly pacify the alignment error of tearing open and causing, save and mould bases disassembly and assembly time is installed.
Floor reinforcing bar is installed on installation mould bases, decrease T beam floor reinforcing bar, time that prestress pipe is installed on T beam pedestal, add the utilization rate of precast pedestal, effectively can reduce the production quantity of T beam prefabricated field pedestal, save predefined region floor space, save place, T beam prefabricated field construction cost to a certain extent.
Alleviate difficulty of construction and the labour intensity of workman, substantially increase project progress.The installation mould bases of T beam floor reinforcing bar all near reinforcement shed is installed, then utilizes straddle truck integral hoisting, take full advantage of the plant equipment such as straddle truck, save the manpower of a dead lift reinforcing bar semi-finished product (between from reinforcement shed to T girder prefabricated pedestal).Utilize prestress pipe positioning bar that mould bases is installed and make prestress pipe positioning bar, then directly install, save the artificial time measuring location prestress pipe, add pipeline precision.
This installation mould bases is simple for production, with low cost.For 40 meters long 2.5 meters high T beams, mould bases makes and only needs all kinds of reinforcing bar about 3.5 tons, nut about (pulling hole) 3600,85 meters, 30mm*30mm angle steel and C20 concrete 4.8 side.
