Embodiment

[0030] The panel 1 of the bridge deck has a length and width of 348.8cm×400cm, and the waist height of the I-steel longitudinal rib 11 and the I-steel beam 9 is 180mm; The spacing between the other limiting shafts is 300mm, and the diameters of the above two limiting shafts are 40mm; the length of the bar hole of the limiting ring 7 is 380mm, and the width is 45mm. After the front bridge plate is connected to the rear bridge plate, the gap between the two is 40mm. The panel 1 and the bottom plate 2 are steel plates with a thickness of 10 mm and a thickness of 8 mm respectively; the thickness of the steel plate beam 10 and the steel plate longitudinal rib are both 8 mm; 20mm; the diameter of the pin hole 5 is 16mm. Both end faces of the box-shaped card slot 6 are welded with closed steel plates (to increase mechanical strength). see Figure 5-Figure 8 In the rectangular frame welded by four I-beams, there is also an I-beam welded along the center line parallel to the width d...

Abstract

The invention discloses a pressure reducing plate with a rapid dismounting and mounting structure. The pressure reducing plate belongs to a component paved on soil in a construction site and allowing an automobile to pass through and comprises multiple bridge plates with the same structure, wherein the structure of each bridge plate is as follows: a bearing framework made of joint steel and steel plates is fixedly connected between a panel and a baseplate with the same length and width as the panel; two connecting mechanisms with the same structure are arranged on two side surfaces at the adjoining part of a front bridge plate and a rear bridge plate; a limiting shaft is welded at the bearing framework of the front bridge plate; a pin hole for inserting a bolt is formed in the limiting shaft; another limiting shaft is welded at the bearing framework of the rear bridge plate; another pin hole for inserting another bolt is formed in the another limiting shaft; a limiting ring with strip holes sleeves the limiting shaft of the front bridge plate and the another limiting shaft of the rear bridge plate. The pressure reducing plate has the characteristics of good convenience and rapidity in dismantling and mounting and high reliability in connection, and is particularly suitable for paving a construction road of a core crossing wall.

Description

technical field [0001] The invention relates to a pavement slab laid on the road surface for cars to pass thereon, in particular to a paving and passing component for laying on the road crossing the core wall in the core wall area of ​​an earth-rock dam. Background technique [0002] As a local material dam type, gravel soil core rockfill dams have significant advantages such as low requirements for basic conditions, small amount of purchased materials, and low total investment. They are more and more widely used in hydropower projects, especially in alpine and valley areas. However, the construction of other dam types requires the transportation of a large amount of steel bars, cement and other materials, and the transportation volume is large. However, due to the limitation of terrain conditions, it is difficult to build roads that meet the transportation requirements. [0003] During the construction of the core rockfill dam, due to factors such as topographical condition...
