Above-mentioned single-box multi-cell formula anchor case, wherein: be provided with polylith stiffener C between said base plate, limit web A, limit web B, the median ventral plate.
Above-mentioned single-box multi-cell formula anchor case, wherein: the thickness of said median ventral plate is greater than limit web A and limit web B.
The present invention compared with prior art has tangible advantage and beneficial effect.Can know by above technical scheme; Be provided with median ventral plate between limit web A and the limit web B; Median ventral plate is according to stressed thicker slightly than limit web A and limit web B, and top board is set to a whole plate, is welded to connect with limit web A, limit web B and median ventral plate; Again base plate is welded on limit web A, limit web B and the median ventral plate, constitutes the single-box multi-cell structure of sealing.Between top board knuckle place and base plate, dividing plate is set, and on the base plate and between the limit web A, limit web B, median ventral plate polylith stiffener C is set, increase the whole rigidity of structure.Be provided with stiffener A at top board inner surface tapping; One-sided single case is indoor, and the both sides in hole are provided with two stiffener B perpendicular to the direction of stiffener A, can reduce the stress on limit, hole and concentrate.
In a word, single-box multi-cell formula anchor case of the present invention has the following advantages:
1, single-box multi-cell formula structure, integral rigidity is big.
2, according to the construction needs, can be designed to any single-box multi-cell formula structure, be the construction conserve space.
3, effectively reduced web piece number, economized with material.
4, the anchor case of bed rearrangement bridge can be arranged to a kind of model, and each is detained between the anchor cable angle difference and can adjust through different wedge type blocks are set, and has not only reduced manufacturing procedure, has accelerated processing progress and easy to process quick.
5, model anchor case of the same race is easy for installation, and rework rate is low, has improved installation effectiveness.
