Embodiment Construction

[0015] like Figure 1~2 As shown, an assembled prefabricated steel fiber concrete pavement includes a plurality of steel fiber concrete poured prefabricated panels 1 laid on the compacted pavement, and a lime-soil cushion 2 is arranged between the prefabricated panels 1 and the compacted pavement; the prefabricated panels 1 includes a plurality of rectangular unit prefabricated panels 11, and a plurality of notches 4 are arranged on the edge of the unit prefabricated panels 11; the circular holes set in the notches 4 penetrate the prefabricated panels 1; the connecting piece 3 is installed on two adjacent prefabricated units In the notch 4 of the panel 11; the bolt 5 passes through the circular hole on the connector 3 and the notch 4 and is fixed with the lime soil cushion. The unit prefabricated panel 11 is generally a square or rectangular structure.

[0016] The notch 4 is a U-shaped notch, and the edge notches 4 of adjacent unit prefabricated panels 11 correspond one by o...

Abstract

The invention discloses a fabricated precast steel fiber concrete pavement. The fabricated precast steel fiber concrete pavement comprises a plurality of precast panels poured by steel fiber concreteand laid on a compacted pavement, wherein a lime soil cushion layer is arranged between the precast panels and the compacted pavement, and a small amount of steel bars or no steel bars are arranged inthe precast panels; a plurality of notches are formed in the panel edges of the precast panels, and circular holes formed in the notches penetrate through the precast panels; and the adjacent precastpanels are connected through connecting pieces. The precast panels are prepared by pouring the steel fiber concrete, so that the use of the steel bars can be reduce to a certain extent or even no useof the steel bars is realized, and under the condition of reducing the weight of concrete, the rigidity and strength of the precast panels are increased, meanwhile the self weight of the precast panels is reduced, and thus transportation is convenient.

Description

technical field [0001] The invention relates to a concrete pavement, in particular to an assembled prefabricated steel fiber concrete pavement. Background technique [0002] At present, the concept of energy conservation and environmental protection advocated by our country has made certain requirements for the construction industry, and advocates environmental protection production in the construction industry. However, at present, most of the temporary roads at construction sites in my country use one-time cast-in-place cement pavement, which will generate a large amount of construction waste after the construction is completed, resulting in a waste of resources. The value of prefabricated precast concrete pavement in construction projects is mainly reflected in two aspects. On the one hand, it is because of the social value brought by the reusable prefabricated concrete. On the other hand, because the cost of prefabricated precast concrete pavement is low and It can be r...
