Abstract
The present invention provides a steel wire net cement orthotropic bridge surface plate which is composed of a plurality of block units divided longitudinally and comprises a steel wire net cement cover plate, a bridge surface pavement unit, a cover plate bottom surface, an orthogonal steel wire net cement closed mouth cross section longitudinal rib and a steel wire net cement transverse rib, wherein the bridge surface pavement unit is combined into a whole body with the steel wire net cement cover plate, orthogonal steel wire net cement closed mouth cross section longitudinal rib is formed into a whole body with the cover plate bottom surface, and the two block units are connected into a whole body by steel bars and wet joint concrete. Because the present invention is made of steel wire net cement, the present invention has the advantages of good elasticity, high toughness, better bending resistance, high torsional strength, light structural weight, steel and lumber saving, better economic performance and convenient construction technology; furthermore, the present invention is suitable for being used as a bridge surface plate of drawbridges or other bridges.
Description
The present invention relates to a kind of bridge deck, particularly relate to a kind of steel wire net concrete cross bridge floor board.
The bridge deck that use in the highway bridge are generally steel bridge deck and reinforced concrete bridge deck plate at present, though steel bridge deck strength of materials height, light weight, but the cost of materials of steel, processing charges and cost of maintenance are higher, development to the highway in China bridge plays restrictive function, because reinforced concrete bridge deck plate weight is big, bridge main part force structure expense is increased, and economy is under some influence.2 phases of " highway " nineteen eighty-two had once been introduced a kind of bridge deck of slab with haunched ribs pattern, its structure comprises flat board, rib on the dull and stereotyped periphery, and perpendicular to triangle reinforcement armpit plate peripheral and that height reduces in striding gradually from the periphery height, this kind slab with haunched ribs is made by Reinforced Concrete Materials, but its structure is not suitable for use in the suspension bridge bridge deck.International application no PCT/GB85/00545 discloses a kind of " improvement of fiber and steel bar reinforced cement ", comprise cover plate, with the orthogonal thereto ferrocement of the cover plate bottom surface all-in-one-piece vertical rib in cross section of remaining silent, though these bridge deck have used fiber to strengthen cement, but there is not transverse stiffener, thereby the transverse distribution ability that the lateral stiffness that makes bridge deck reaches load is affected, and this kind structure can only be used for little span bridge deck simultaneously.
The object of the present invention is to provide the existing holistic orthogonal thereto ferrocement vertical rib in cross section of remaining silent made from it in a kind of its cover plate bottom surface, it is the steel wire net concrete cross bridge floor board of the ferrocement cross rib of rectangle that cross section is arranged again.
Steel wire net concrete cross bridge floor board of the present invention is made of the piece spare unit of vertical division, be provided with the ferrocement cover plate at its end face, the deck paving that is combined into one with lid surface, and to make the remain silent vertical rib in cross section and cross section of holistic orthogonal thereto ferrocement with the cover plate bottom surface be the ferrocement middle part cross rib and the end cross rib of rectangle, connect into integral body by reinforcing bar and wet joint concrete between two part unit, the ferrocement cross rib at ferrocement bridge deck two ends be convenient to handle bridge deck joint and with the combining of other structures.Deck paving is generally cement concrete constructions, bears vehicular load jointly with cover plate.The remain silent cross section of the vertical rib in cross section of ferrocement is generally spill.
Used ferrocement material in the steel wire net concrete cross bridge floor board of the present invention, the label of its cement mortar is 40-60 number, cement consumption 400-800kg/m, water/binder ratio is 0.3-0.45, steel wire is the not zinc-coated wire of ultimate strength 450-750mpa, diameter 0.6-1.2mm, size of mesh opening 6 * 6-15 * 15mm.
Ferrocement cover sheet thickness in the steel wire net concrete cross bridge floor board of the present invention is generally 3-5cm.The remain silent thickness of vertical rib in cross section and ferrocement cross rib of ferrocement is generally 3-5cm, and the cross rib spacing is 80-150cm.
The selection of the size of steel wire net concrete cross bridge floor board each several part of the present invention and each parameter of ferrocement material then according to bridge general arrangement decide.
The advantage of steel wire net concrete cross bridge floor board of the present invention is to have better elastic, toughness and bending resistance, torsional strength, lightweight construction, span is big, saves steel, timber, than the steel bridge deck 800-1200 unit/rice of reducing investment outlay, has better economic.Construction technology of the present invention is easy, is suitable as the bridge deck of suspension bridge or other bridge.
Describe the present invention in detail below in conjunction with accompanying drawing.

Steel wire net concrete cross bridge floor board of the present invention comprises the piece spare unit of vertical division, be provided with ferrocement cover plate 1 at its end face, the deck paving 4 that is combined into one with cover plate 1 surface, and to make the remain silent vertical rib 2 in cross section and cross section of holistic orthogonal thereto ferrocement with cover plate 1 bottom surface be the steel wire cement middle part cross rib and the end cross rib 3 of rectangle, wet joint concrete 6 between 5, two parts of reinforcing bar of the cover plate and the vertical rib in cross section of remaining silent.Wherein deck paving 4 is a cement concrete.
