Abstract
The utility model relates to a continuous box girder steel formwork welded with stainless steel thin plate, which comprises a steel formwork bottom plate, a side baffle plate outside the edge of the steel formwork bottom plate, and stiffening channel steels and connection plates which are longitudinally and horizontally connected below the steel formwork bottom plate, and a grider support which forms a bolted connection with the connection plates; a stainless steel thin plate is welded on the upper surface of the steel formwork bottom plate, and intermittent-shaped welding points are arranged between the steel formwork bottom plate and the stainless steel thin plate. The utility model not only can greatly enhance the appearance quality of movable frame construction continuous box grider concrete, and can greatly enhance the construction process of a box grider , can improve the economic benefit of construction of the box grider, can be widely applied to engineering projects with strict appearance quality requirements on concrete and great engineering quantities, is suitable for the cast-in-place concrete construction technology of a movable frame steel formwork, and is also suitable for precast concrete steel formwork.
Description
Technical field
The utility model relates to the steel form that a kind of concrete formation is used, particularly a kind of steel form of bridge box and beam construction.
Background technology
In bridge construction, the superstructure of bridge can adopt prestressed in-situ depositing concrete continuous box-beam structure, and existing prestressed in-situ depositing concrete continuous case beam generally adopts mobile formwork to construct.According to the requirement of bridge customized specifications, existing case beam external mold all adopts steel form, can reduce construction joint like this, improve presentation quality.But in the construction of bridge spanning the sea, the punching block die face easily produces corrosion, influence the useful life longevity and the concrete presentation quality of punching block, cast-in-situ box girder is long to the pour concrete time from formwork erection simultaneously, and the mold oil that die face adopts surface in work progress easily adheres to foreign material, is difficult to remove clean.And, soak the back die face at rainwater and easily get rusty, cause the presentation quality of concrete continuous box girder not bright and clean.This is the disadvantage that adopts steel form and release agent, also is the construction difficult problem that presses for solution at present.
Because bridge requires high to the concrete presentation quality; for improve concrete presentation quality, protection template, prolong template application life, be convenient to construction; prior art is to use the template lacquer on steel form; use the concrete flat appearance after template is coated with lacquer smooth; solid colour; easy construction; overcome the shortcoming of steel form and mold oil; but it is limited that template is coated with lacquer reusable number of times; after using 3 times at most, need carry out the template cleaning again and be coated with formwork oil, time-consuming; both relate to economical efficiency, also related to the programming problem.
The utility model content
In order to overcome the deficiency of existing steel form, the utility model provides a kind of continuous box girder steel form that is welded with stainless sheet steel, the panel useful life longevity that solves the conventional steel template is poor, easily cause the not bright and clean technical problem of presentation quality of concrete after using mold oil, and solve time-consuming, the less economical problem of use template lacquer on the panel of steel form.
The technical scheme that its technical problem that solves the utility model adopts is:
This continuous box girder steel form that is welded with stainless sheet steel, put more energy into channel-section steel and the junction plate that comprise the side shield at steel form base plate, steel form bottom edge place, below the steel form base plate, connects in length and breadth, prop up with the bolted truss of junction plate, it is characterized in that: the upper surface at the steel form base plate is welded with stainless sheet steel, and the pad that is interrupted shape is arranged between steel form base plate and the stainless sheet steel.
Above-mentioned pad can be point-like or strip.
But above-mentioned pad grid-shaped evenly distributes or quincunx even distribution.
The spacing of above-mentioned pad can be 10～30cm.
The beneficial effects of the utility model are as follows:
The utility model is sticked on stainless sheet steel on steel form, improved the presentation quality of case beam concrete, smooth smooth, the solid colour of concrete presentation quality, feel exquisiteness, glossy, pollution-free.The utility model helps improving Surface Quality of Concrete, shows concrete " true qualities " fully, arrives " clear-water concrete " effect.
The utility model relatively can be saved the engineering total cost greatly with adopting the template lacquer.The general consumption 10m of template lacquer
2/ kg, material price are 38 yuan/kg, and reusable 3 times, the actual average expense is 1.26 yuan/m
2* inferior.And the average cost of stainless steel template plate material is 1.5 yuan/m
2* inferior, in addition, template is coated with lacquer per three and is striden and will smear again, and stainless sheet steel is permanent, and like this, the template lacquer needs labour cost, and according to the preliminary statistics, adopting template to coat with lacquer required labour cost is 1.7 yuan/m
2* inferior.Also can reduce invisible project management fee greatly, according to the preliminary statistics, adopt that to stick on the project management fee that the stainless sheet steel method reduced be 2.2 yuan/m
2* inferior.In a word, the total cost of template lacquer is 5.16 yuan/m
2* inferior, and the 1.5 yuan/m of total cost of stainless sheet steel
2* inferior.
The utility model has been accelerated the construction speed of template, can more obviously improve the construction overall progress, improves the effect of construction greatly.
The utility model construction is simple, and in a single day stainless sheet steel is burn-on and just can be used all the life, and operational sequence is easy.
The utility model can be strengthened the protection to template, prolongs the application life of template.The utlity model has well anticorrosion, antirust function, can adapt to various construction environment, the place that particularly marine punching block gets rusty easily has more advantage.
In a word, the utility model not only can improve the concrete presentation quality of Construction Through Form on Traveler continuous box girder greatly, also can improve the box girder construction progress greatly, also can improve the economic benefit of box girder construction, can be strict in Surface Quality of Concrete and engineering that engineering quantity is big in extensive use.Be not only applicable to mobile formwork steel form cast-in-situ concrete construction technology, applicable to the precast concrete steel form yet.
