Abstract

The utility model discloses an expansion joint component for concrete pavement, relating to an expansion joint structure component for the concrete pavement, and comprising an expansion joint cover plate, a fixing plate and reinforced bars. Teeth on one side of the expansion joint cover plate are engaged with teeth on one side of the fixing plate, a gap is arranged between a tooth end and the bottom of a tooth groove, the expansion joint cover board and the fixing plate are arranged on a same plate and are respectively and fixedly connected with the reinforced bars.

Description

Concrete paving expansion joint (E.J.) member

The utility model relates to a kind of member that is used for the concrete paving expansion joint (E.J.).

The concrete paving of existing road, playing field, sports ground can expand during high temperature, can shrink during low temperature, therefore concrete paving leaves expansion joint (E.J.) usually, and before this case applying date, expansion joint (E.J.) is used pointing such as joint fillings such as pitch, matizhi usually, when high temperature, pointing often overflows expansion joint (E.J.), pollutes the road surface, during low temperature, pointing shrinks embrittlement, and the fragile cracking of seam crossing concrete plate has the car of jumping phenomenon during driving, the stationarity of influence driving.

The purpose of this utility model is: a kind of technical scheme of concrete paving expansion joint (E.J.) member is provided, when this expansion joint (E.J.) member is used for the concrete paving expansion joint (E.J.), need use pointing, during driving, vehicle is steady, does not have the car of jumping phenomenon, and the expansion joint (E.J.) place of concrete plate can not damage.

The technical solution of the utility model is: concrete paving expansion joint (E.J.) member comprises the expansion joint (E.J.) cover plate, fixed head and reinforcing bar, the tooth of expansion joint (E.J.) cover plate on one side is meshed with tooth on fixed head one side, leave the gap between at the bottom of increment and the teeth groove, expansion joint (E.J.) cover plate and fixed head at grade, the expansion joint (E.J.) cover plate is fixedlyed connected with reinforcing bar respectively with fixed head.When this expansion joint (E.J.) member is used for concrete paving, the expansion joint (E.J.) cover plate of concrete paving expansion joint (E.J.) member is covered on expansion joint (E.J.), the reinforcing bar that is connected with the expansion joint (E.J.) cover plate is all built in concrete with the reinforcing bar of fixedlying connected with fixed head, and the upper surface of the upper surface of the concrete paving adjacent with fixed head with the expansion joint (E.J.) cover plate and expansion joint (E.J.) cover plate, fixed head is on a horizontal plane.Perhaps fixed head overlays on the junction plate, and fixedlys connected with junction plate, and junction plate is fixedlyed connected with reinforcing bar.The reinforcing bar of fixedlying connected with expansion joint (E.J.) cover plate or fixed head is "  " shape.

Major advantage of the present utility model is: overcome the shortcoming that adopts the pointing joint filling, during high temperature, do not have pointing and overflow expansion joint (E.J.), pollute the paving, during driving, can not produce the jiggly jumping car of vehicle phenomenon, during low temperature, can be because of pointing embrittlement does not bring harm yet, the expansion joint (E.J.) place of concrete plate, not sensitive for damages.This expansion joint (E.J.) member is not only applicable to the expansion joint (E.J.) in road, place, and is applicable to the shrinkage joint of bridge, make simply, but unit in charge of construction's self manufacture, easy construction, durable in use.Adopt this expansion joint (E.J.) member, can satisfy the concrete paving needs of the amount of expanding and the big stroke of bridge greatly.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1: concrete paving expansion joint (E.J.) member schematic diagram 1,

Fig. 2: concrete paving expansion joint (E.J.) member schematic diagram 2,

The vertical view of Fig. 3: Fig. 2,

Fig. 4: reinforcing bar and expansion joint (E.J.) cover plate welding schematic diagram,

Fig. 5: reinforcing bar and fixed head welding schematic diagram.

Fig. 1 is an embodiment of concrete paving expansion joint (E.J.) member, cover on road or place concrete paving expansion joint (E.J.) or bridge expanssion joint 6 expansion joint (E.J.) cover plate 1 and fixed head 4 at grade, tooth on 4 one limits of tooth on the limit of expansion joint (E.J.) cover plate 1 and the fixed head (see figure 3) that is meshed leaves spacing between 9 at the bottom of increment 8 and the teeth groove.How much deciding of the number of teeth by the length of paving expansion joint (E.J.), the paving expansion joint (E.J.) is long, the number of teeth is many, and the paving expansion joint (E.J.) is short, and the number of teeth is few, expansion joint (E.J.) cover plate 1 welds with an end of reinforcing bar 5, how much deciding of reinforcing bar by the size of expansion joint (E.J.) cover plate, the big reinforcing bar of expansion joint (E.J.) cover plate is many, on the contrary reinforcing bar is then few, the one end welding of fixed head 4 and reinforcing bar 3, the reinforcing bar 5 and 3 the other end are used for pouring into concrete.

Embodiment 2:

With the difference of embodiment 1 be: fixed head 4 overlays (see figure 2) on the junction plate 2, and is welded as a whole with junction plate, and junction plate 2 welds together with an end of reinforcing bar 3.

Embodiment 3:

With the difference of embodiment 1 or 2 be: embodiment 1 and 2 expansion joint (E.J.) cover plate, the profile of tooth on the fixed head are rectangle, and the shape of the tooth of expansion joint (E.J.) cover plate 1 and fixed head 4 on one side is square in addition, trapezoidal, the shape of arc, triangle, slot form and tooth is complementary.

Embodiment 4:

With embodiment 1 or 2,3 difference be: be "  " shape (seeing Fig. 4,5) with the reinforcing bar 5 or 3 that expansion joint (E.J.) cover plate 1 or fixed head 4 are fixedlyed connected respectively, reinforcing

bar

5 and 1 welding of expansion joint (E.J.) cover plate, reinforcing bar 3 and fixed head 4 welding.
