Abstract
The utility model discloses a kind of Lightweight core mould pre-stress concrete H type composite plates, and it is the H type prefabricated components that horizonal web plate and two side bars arranged along its length are formed.Its horizonal web plate is the unidirectional multi-ribbed plate of Lightweight core mould, and it is made up of successively light hollow slat, longitudinal girt strip and panel；Core of the light hollow slat in Prefabrication as one-way sealing rib top plate, after the completion of production, permanently remained in as heat-insulation layer among top plate.The dosage of concrete in horizontal top was so both reduced, and had reduced deadweight, and saved material cost and improved heat insulating effect.So the utility model reduces cost on the premise of bearing capacity and globality and its security is ensured, simplifies construction, economic benefit is fairly obvious.
Description
Technical field
The present invention relates to a kind of prefabricated H templates, and in particular to a kind of Lightweight core mould pre-stress concrete H type composite plates.
Background technology
In the construction of the walkway bridge on overline bridge and river channel in city and high-grade highway, often at present
There are two kinds of forms of steel construction and cast-in-situ reinforced concrete structure, cast-in-situ reinforced concrete structure has the advantages of low cost, easy to maintain,
But construction is complicated, and the duration is longer, influences urban transportation and passes through；The Steel Structure Installation duration is short, but cost is higher, and later maintenance into
This height.Raised speed with the increasingly crowded and comprehensive regulation in small rural river course of urban transportation, various walkway bridges will increasingly
Increase.Therefore, to reduce the construction cost of pedestrian's bridge and shortening the duration, new large-span prestressed concrete beam plate right and wrong are researched and developed
It is often necessary.
The content of the invention
It is an object of the invention to provide one kind, from heavy and light, span, big, low cost, plate are wide in the precast prestressed of 3m or so
Concrete H type beam slabs, it, to reach reduction cost, is shortened into the purpose of duration with various pedestrian's bridges.
The invention discloses a kind of Lightweight core mould pre-stress concrete H type composite plates, and it is for horizonal web plate and along its length
The H type prefabricated components that two side bars of arrangement are formed, the horizonal web plate are the unidirectional multi-ribbed plate of Lightweight core mould, two vertical edges
Beam is the isometric pre-stress concrete square type beam in both sides and horizonal web plate that web is arranged in along horizonal web plate length direction.
The Lightweight core mould one-way sealing rib web, is made up of successively light hollow slat, longitudinal girt strip and panel；Lightweight is empty
Core of the heart batten in Prefabrication as one-way sealing rib web, after the completion of production, top is permanently remained in as heat-insulation layer
Among plate.
The bottom of the light hollow slat core is provided with tongue and groove along its length, when making to pour the concrete of longitudinal girt strip, its
Bottom is extended with the edge of a wing, for fixing light hollow slat.
The light hollow slat is less than 800kg/m3 using unit weight, and intensity is more than 3MPa, and thermal conductivity factor is less than 0.3W/
(m*k) lightweight concrete material, such as Aerated Concrete, stalk fibre concrete etc..
Longitudinal girt strip is less than 0.5W/ (m*k) lightweight aggregate structural thermal insulation concrete using thermal conductivity factor.
Steel bar stress in the vertical side bar uses deformed bar, and the both ends of beam are each provided with several lateral direction penetratings
Circular hole.
The present invention is high for horizonal web plate and the integral prefabricated part of H types of two vertical side bar compositions, the section of two side bars
Degree greatly increases, and uses prestressed structure, improves rigidity and bearing capacity, while its horizonal web plate is sandwich using one-way sealing rib
The structural form of plate, reduce the dosage of concrete in horizonal web plate, reduce deadweight, saved material cost and improved thermal insulation separation
Thermal effect.So the present invention reduces cost on the premise of bearing capacity and globality and its security is ensured, simplifies construction,
Economic benefit is fairly obvious.
Brief description of the drawings
Fig. 1 is the schematic perspective view of the present invention.
Fig. 2 is the longitudinal section sectional view of the present invention.
Fig. 3 is the schematic perspective view of Lightweight core mould.
Embodiment
As Figure 1-3, present embodiment discloses a kind of Lightweight core mould pre-stress concrete H type composite plates, it is horizontal top 2
And the integral prefabricated part of H types that the two vertical side bars 1 arranged along its length are formed, the horizonal web plate 2 is light core
The unidirectional multi-ribbed plate of mould, two vertical side bars 1 are isometric to be arranged in the both sides of web and horizonal web plate along horizontal top length direction
Pre-stress concrete square type beam.
The Lightweight core mould one-way sealing rib web 2, by light hollow slat 21, longitudinal girt strip 22 and panel 23 successively group
Into；Core of the light hollow slat 21 in Prefabrication as one-way sealing rib top plate, it is permanent as heat-insulation layer after the completion of production
Ground is retained among top plate.
The bottom of the light hollow slat 21 is provided with tongue and groove 211 along its length, when making to pour the concrete of longitudinal girt strip 22,
Its bottom is extended with the edge of a wing 221, for fixing light hollow slat.
The light hollow slat 21 is less than 800kg/m3 using unit weight, and intensity is more than 3MPa, and thermal conductivity factor is less than 0.3W/
(m*k) lightweight concrete material, such as Aerated Concrete, stalk fibre concrete etc..
Longitudinal girt strip 22 is less than 0.5W/ (m*k) lightweight aggregate structural thermal insulation concrete using thermal conductivity factor.
Steel bar stress in the vertical side bar 1 uses deformed bar, and the both ends of beam are each provided with several transverse directions and passed through
Logical circular hole 11.
The integral prefabricated part of H types that the present embodiment forms for horizonal web plate and two vertical side bars, the section of two side bars
Highly greatly increase, and use prestressed structure, improve rigidity and bearing capacity, while its horizonal web plate is pressed from both sides using one-way sealing rib
The structural form of core, reduce the dosage of concrete in horizonal web plate, reduce deadweight, saved material cost and improved insulation
Effect of heat insulation.So the present invention reduces cost on the premise of bearing capacity and globality and its security is ensured, simplifies and apply
Work, economic benefit are fairly obvious.
