Description
Technical field
The present invention relates to the profiled sheet of use in a kind of building, and the building roof plate and the job practices thereof that adopt this profiled sheet.
Background technology
At present, for large scale industry and civilian construction roofing, it is to lay profiled sheet earlier to do soffit formwork that a kind of method is arranged, and assembling reinforcement on profiled sheet then, fluid concrete form the composite floor roofing.In order to make profiled sheet have certain bending rigidity, need steel plate be bent into the longitudinal rib with Wave crest and wave trough.The bending rigidity of existing profiled sheet is provided by steel plate fully, mainly by steel plate thickness and the decision of longitudinal rib height two aspects.When increasing steel plate thickness, steel using amount will significantly rise, and is uneconomical economically, and the longitudinal rib height receives the restriction of reinforced concrete roof board thickness, can not be De Taigao.At present the longitudinal rib height of the conventional profiled sheet that adopts is 51～76mm, and steel plate thickness is 0.75～1.6mm, and span was not 2.5～3.5m when the floor span centre was not established interim support.
Existing profiled sheet has following defective:
1, the bending rigidity of profiled sheet is low, and roof panel is striden can not be too big, and construction is inconvenient, is difficult to be applicable to the construction of long-span roofing plate.
2, owing to local stable requirement, steel plate thickness is bigger, and steel using amount is bigger than normal.
Roof panel is the main member in the building, and is very crucial to speed of application, the cost influence of whole building.1), the cast-in-situ concrete roof panel large scale industry at present and civilian construction roofing mainly contain following several kinds of roof panel:, support is set, assembling reinforcement on template, fluid concrete are processed; This roof panel good integrity; But this roof panel needs a large amount of templates and support from great, and speed of application is slow; Difficulty of construction is also very big, seldom adopts except special requirement in the actual engineering.2), the prestressed concrete large roof slab, adopt the high-strength steel concrete steel as prestressed reinforcement, the steel form pre-tensioning system produces.This roof panel rigidity is big, and light with span cast-in-situ concrete roof panel from anharmonic ratio, shortcoming is a complex manufacturing, and installation difficulty is big.3), the color profiling steel plate roof panel, have from heavy and light, convenient installation, shortcoming is that poor durability, weight capacity are less, the steel consumption amount is big.
Summary of the invention
The present invention provides a kind of concrete to strengthen profiled sheet, building roof plate and job practices thereof; Solve the existing technical problem that composite floor roofing medium-pressure type steel plate bending rigidity is low, steel using amount is big, and solve existing cast-in-situ concrete roof panel from great and speed of application slow, color profiling steel plate roof panel poor durability and the little technical problem of bearing capacity.
The technical solution adopted for the present invention to solve the technical problems is:
This concrete strengthens profiled sheet, comprises the steel plate body, on the steel plate body, is intervally distributed with vertical wave trough, and said vertical wave trough is to recessed trough groove, is cast with concrete in the trough groove in advance, is combined as a whole with the trough groove behind the concrete curing.
Being shaped as trapezoid, falling trapezoidal or rectangle of said trough groove, spaced apart being useful on is connected stamped groove closely on the cell wall of trough groove with concrete.
Said steel plate body one side is colluded groove, and opposite side has and colludes the crisperding that groove is connected.
Said steel plate body runs through each trough groove and concrete horizontal stiffener along the trough flute length to being intervally distributed with, and perhaps the steel plate body connects each trough groove and concrete steel concrete ribs along the trough flute length to being intervally distributed with.
Said concrete is ordinary concrete, fibrous concrete, polymer concrete, steel concrete or grouting material concrete.
Said TOC upwards is dentation protrusion steel plate body, and protrusion height is 5～15mm.
Said inside concrete is along growing to being provided with longitudinal reinforcement.
Said longitudinal reinforcement is applied with prestressing force.
This concrete strengthens profiled sheet and is used to make the single span plate, perhaps the multispan continuous slab.
This employing concrete strengthens the building roof plate of profiled sheet, strengthen profiled sheet, the roof panel reinforcing bar of colligation above concrete strengthens profiled sheet by concrete, and the back pouring concrete of profiled sheet top is formed by stacking.
This employing concrete strengthens the building roof board construction method of profiled sheet, and construction sequence is following:
Beneficial effect of the present invention is following:
The present invention since in the wave trough of profiled sheet fluid concrete in advance, make integral body of concrete and profiled sheet formation, significantly promoted the bending rigidity of profiled sheet, and the thickness of profiled sheet attenuate greatly, steel using amount significantly reduces.Because steel using amount reduces, and the cost of production of profiled sheet is reduced significantly.Fluid concrete in the wave trough of profiled sheet does not need template, makes very convenient.
Can be intervally distributed with stamped groove on the wave trough of profiled sheet, thereby concrete is connected closely with wave trough.The steel plate body can be provided with horizontal stiffener or steel concrete ribs at a certain distance, and concrete is connected better with the steel plate body, forms overall structure.Can be provided with longitudinal reinforcement in the concrete, the bending rigidity of profiled sheet is further strengthened, intensity increases simultaneously.But the longitudinal reinforcement stretch-draw prestressing force of inside concrete further strengthens the bending rigidity of profiled sheet, also can save steel.TOC upwards is dentation protrusion steel plate body, and the back pouring concrete is connected closely with this plate of steel.
The building roof plate that adopts concrete to strengthen profiled sheet is compared with conventional cast-in-situ steel reinforced concrete roof panel, from heavy and light, does not need the installation and removal template, can accelerate speed of application greatly.Compare with the prestressed concrete large roof slab; Not only structural integrity is strong, cost of production is low, job practices is easy to adopt building roof plate of the present invention; Obviously strengthen owing to adopt concrete to strengthen back base plate bending rigidity, the roof panel span of not establishing interim support can enlarge markedly.Compare with traditional pressing steel plate roofing plate, adopt that building roof plate good endurance of the present invention, bearing capacity are high, steel using amount is few.
Concrete of the present invention strengthens the roof panel construction that profiled sheet is applicable to large scale industry and civilian construction roofing and building reconstruction engineering, alternative prestressed concrete large roof slab.
