Abstract
The invention discloses a kind of Lightweight core mould pre-stress concrete H type composite plates, it is the H type prefabricated components of horizonal web plate and two side bars arranged along its length formation.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；Light hollow slat in Prefabrication as one-way sealing rib top plate core, after the completion of production, permanently remained in as heat-insulation layer among top plate.The consumption of concrete in horizontal top had so both been reduced, deadweight is reduced, material cost has been saved and has improved heat insulating 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.
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 low cost, it is easy to the advantage of maintenance,
But construction is complicated, the duration is longer, and influence urban transportation is passed through；The Steel Structure Installation duration is short, but cost is higher, and later maintenance into
This height.With the comprehensive regulation speed-raising in the increasingly crowded and 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
Big from heavy and light, span it is an object of the invention to provide one kind, low cost, plate is wide in the precast prestressed of 3m or so
Concrete H type beam slabs, to reach reduction cost, the purpose of duration is shortened by it with various pedestrian's bridges.The invention discloses one
Lightweight core mould pre-stress concrete H type composite plates are planted, it is the H types of horizonal web plate and two side bars arranged along its length formation
Prefabricated components, the horizonal web plate is the unidirectional multi-ribbed plate of Lightweight core mould, and two vertical side bars are along horizonal web plate length direction
It is arranged in the both sides of web and the pre-stress concrete square type beam that horizonal web plate is isometric.The Lightweight core mould one-way sealing rib web, by light
Matter hollow lath, longitudinal girt strip and panel are constituted successively；Light hollow slat is used as one-way sealing rib web in Prefabrication
Core, after the completion of production, is permanently remained among top plate as heat-insulation layer.The bottom of the light hollow slat core is along length
Degree direction is provided with tongue and groove, and 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.Institute
State light hollow slat and 800kg/m3 is less than using unit weight, 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 knot using thermal conductivity factor
Structure heat insulated concrete.Steel bar stress in the vertical side bar uses deformed bar, and the two ends of beam are each provided with several transverse directions and passed through
Logical circular hole.The present invention is horizonal web plate and the integral prefabricated part of H types of two vertical side bar compositions, and the section of two side bars is high
Degree is greatly increased, 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, reduces the consumption of concrete in horizonal web plate, reduces deadweight, has saved material cost and has 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.Illustrate schematic perspective views of the Fig. 1 for the present invention.Fig. 2 is longitudinal section sectional view of the invention.Figure
3 be the schematic perspective view of Lightweight core mould.As Figure 1-3, present embodiment discloses a kind of Lightweight core mould is pre- for embodiment
Stress concrete H type composite plates, it is overall for the H types of horizontal top 2 and the two vertical formation of side bars 1 arranged along its length
Prefabricated component, the horizonal web plate 2 is the unidirectional multi-ribbed plate of Lightweight core mould, and two vertical side bars 1 are along horizontal top length direction cloth
It is placed in the both sides of web and the pre-stress concrete square type beam that horizonal web plate is isometric.The Lightweight core mould one-way sealing rib web 2, by lightweight
Hollow lath 21, longitudinal girt strip 22 and panel 23 are constituted successively；Light hollow slat 21 is used as one-way sealing rib in Prefabrication
The core of top plate, after the completion of production, is permanently remained among top plate as heat-insulation layer.The bottom of the light hollow slat 21
Tongue and groove 211 is provided with along its length, and when making to pour the concrete of longitudinal girt strip 22, its bottom is extended with the edge of a wing 221, for fixing lightweight
Hollow lath.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 using thermal conductivity factor
0.5W/ (m*k) lightweight aggregate structural thermal insulation concrete.Steel bar stress in the vertical side bar 1 uses deformed bar, the two ends of beam
It is each provided with the circular hole 11 of several lateral direction penetratings.The present embodiment is that the H types that horizonal web plate and two vertical side bars are constituted are whole
Body prefabricated component, the depth of section of two side bars is greatly increased, and uses prestressed structure, improves rigidity and bearing capacity, simultaneously
Its horizonal web plate uses the structural form of one-way sealing ribbed sandwich panel, reduces the consumption of concrete in horizonal web plate, reduces deadweight, saves
About material cost and improve heat insulating effect.So the present invention is before bearing capacity and globality and its security is ensured
Put and reduce cost, simplify construction, economic benefit is fairly obvious.
