Abstract
The invention discloses a kind of pre-stress concrete H type beam slabs, it is the H type prefabricated components of horizonal web plate and the two side bars formation arranged along its length, the horizonal web plate is reinforced concrete multi-ribbed sandwich flat board, and two vertical side bars are the isometric pre-stress concrete square type beam in the both sides and horizonal web plate for being arranged in web along horizonal web plate length direction.The horizonal web plate is the frame-like structures surrounded by upper and lower panel and positioned at the longitudinal and transverse ribbed belt of arranged crosswise between the two, be divided into the region between upper and lower panel in some individual cavities, individual cavities along length direction and the width arrangement of upper and lower panel respectively by longitudinal and transverse ribbed belt fills corresponding light filling block.H types beam slab of the invention, the depth of section of its two side bars is greatly increased, and uses prestressed structure, rigidity and bearing capacity are improve, while its horizonal web plate reduces the consumption of concrete in horizonal web plate using the sandwich structural form of close rib, deadweight is reduced, material cost has been saved.So the present invention reduces cost, simplifies construction on the premise of bearing capacity and globality and its security is ensured, built for pedestrian's bridge, economic benefit is fairly obvious.
Description
Technical field
The present invention relates to a kind of prefabricated H type beam slabs, and in particular to a kind of pre-stress concrete H type beam slabs.
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 more long, and influence urban transportation is passed through；The Steel Structure Installation duration is short, but cost is higher, and later maintenance into
This height.As the comprehensive regulation in the increasingly crowded and small rural river course of urban transportation is raised speed, 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
Precast prestressed concrete H type beam slabs are planted, it is the prefabricated structure of H types of horizonal web plate and the two side bars formation arranged along its length
Part, the horizonal web plate is reinforced concrete multi-ribbed sandwich flat board, and two vertical side bars are to be arranged in abdomen along horizonal web plate length direction
The both sides of plate and the isometric pre-stress concrete square type beam of horizonal web plate.The horizonal web plate is it by upper and lower panel and positioned at both
Between arranged crosswise the frame-like structures that surround of longitudinal and transverse ribbed belt, longitudinal and transverse ribbed belt respectively along upper and lower panel length direction and
Be divided into region between upper and lower panel to be filled in some individual cavities, individual cavities by width arrangement fills out accordingly
Fill block.To improve the bearing capacity and rigidity of plate, the steel bar stress in the vertical side bar uses deformed bar.To reduce certainly
Weight, in the web below plate be fiber cement board, the filling block uses lightweight filler.The present invention is horizonal web plate
And two integral prefabricated parts of H types of vertical side bar composition, the depth of section of two side bars is greatly increased, and uses prestressing force knot
Structure, improves rigidity and bearing capacity, while its horizonal web plate reduces concrete in horizonal web plate using the sandwich structural form of close rib
Consumption, reduce deadweight, saved material cost.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.
Brief description of the drawings
Fig. 1 is schematic perspective view of the invention.Fig. 2 is cross section view of the invention.Fig. 3 is longitudinal section section view of the invention
Figure.
Specific embodiment
As Figure 1-3, present embodiment discloses a kind of precast prestressed concrete H type beam slabs, it is for horizonal web plate 2 and along its length
The H type prefabricated components that two side bars 1 of direction arrangement are formed, the horizonal web plate 1 is reinforced concrete multi-ribbed sandwich flat board, and two are erected
Straight flange beam 2 is the isometric pre-stress concrete square type beam in the both sides and horizonal web plate for being arranged in web along horizonal web plate length direction.Institute
It is by lower panel 21, top panel 22 and the longitudinal rib band 23, cross rib band positioned at arranged crosswise between the two to state horizonal web plate 2
Region segmentation between lower panel 21, top panel 22 is some only with 24 with 23, cross rib by 24 frame-like structures for surrounding, longitudinal rib
Vertical cavity, is filled with corresponding filling block 25 in individual cavities.To improve the bearing capacity and rigidity of plate, the vertical side bar 1
In steel bar stress use deformed bar.Be reduce deadweight, in the web 2 below plate 21 be fiber cement board, it is described
Filling block 25 uses lightweight filler.The present embodiment is integral prefabricated for the H types of horizonal web plate and two vertical side bar compositions
Part, the depth of section of two side bars is greatly increased, and uses prestressed structure, improves rigidity and bearing capacity, while its level
Web reduces the consumption of concrete in horizonal web plate using the sandwich structural form of close rib, reduces deadweight, saved material into
This.So the present embodiment reduces cost, simplifies construction on the premise of bearing capacity and globality and its security is ensured, pass through
Ji benefit is fairly obvious.
