Abstract
The utility model belongs to the technical filed of bridge expansion devices and particularly relates to a bridge expansion device. The bridge expansion device is mainly characterized by comprising anchoring reinforced steel bars, two pieces of channel steel with clamp grooves and a water stopping band with clamp strips at two ends. The clamp strips are clamped into the clamp grooves. A first arc-shaped groove is formed in the upper end of each clamp groove. A second arc-shaped groove is formed in the upper end of each clamp strip. A circular compressing strip is disposed between each first arc-shaped groove and the corresponding second arc-shaped groove. During mounting, the clamp strips of the water stopping band are placed into the clamp grooves, the circular compressing strips are pushed along the upper ends of the clamp strips to the positions between the first arc-shaped grooves and the second arc-shaped grooves. The bridge expansion device has the advantages that during mounting and replacement, pushing of the circular compressing strips is easy, untight sealing caused by twisting of the circular compressing strips is avoided, convenient and fast mounting and replacement are achieved, and replacement can be performed without stopping traffic.
Description
Technical field
The utility model belongs to bridge extension joint technical field, relates in particular to bridge extension joint.
Background technology
On the bridge of highway or railway, a plurality of bridge extension joints are installed.The bridge extension joint using at present comprises the waterstop that is positioned at the shaped steel of both sides and is positioned at centre, relative inner at shaped steel is provided with draw-in groove, at waterstop two ends with card article, during installation, card article is snapped in draw-in groove, between card article upper end and draw-in groove, be pressed into triangle compression bar, to reach, compress the object that card article avoids card article to deviate from and seal from draw-in groove.There is following defect in this bridge extension joint: one, and because compression bar is triangle, in installation process, compression bar easily rolls, and causes compression bar upper end and draw-in groove poorly sealed, causes to leak etc., shortens bridge application life; Its two, between compression bar top and draw-in groove, be linear sealing, easily cause poorly sealedly, reduce bridge life; Its three, compression bar is triangle, in installation process, resistance is installed large, is not easy to install, and installs and change inconvenient, need to suspend traffic.
Utility model content
The technical problem of solution of the present utility model is just to provide a kind of good sealing effect, installation and changes bridge extension joint easily.
The technical solution adopted in the utility model is: comprise anchor bar, the waterstop with the shaped steel of draw-in groove and two ends with card article, described card article is stuck in described draw-in groove, in described draw-in groove upper end, be provided with the first circular groove, in described card article upper end, be provided with the second circular groove, between described the first circular groove and the second circular groove, be provided with circular compression bar.
Its additional technical feature is:
In described circular compression bar with along the axial cavity of card article.
Bridge extension joint provided by the utility model compared with prior art, have the following advantages: one, owing to comprising anchor bar, waterstop with the shaped steel of draw-in groove and two ends with card article, described card article is stuck in described draw-in groove, in described draw-in groove upper end, be provided with the first circular groove, in described card article upper end, be provided with the second circular groove, between described the first circular groove and the second circular groove, be provided with circular compression bar, when mounted, the card article of waterstop is inserted in draw-in groove, then circular compression bar is allocated between the first circular groove and the second circular groove along card article upper end to both sides by manipulator, circular compression bar is stuck in the first circular groove and the second circular groove tightly, avoided card article to deviate from from draw-in groove, and between circular compression bar and the first circular groove and the second circular groove, be face sealing, sealing effectiveness is better, and in installation and Renewal process, circular compression bar advances and is more prone to, can not cause poorly sealed because of circular compression bar twisting, install and change more convenient, in the situation that not breaking off a friendship, just can change, they are two years old, due in described circular compression bar with along the axial cavity of card article, by in circular compression bar progradation, highly can reducing up and down of circular compression bar, be more convenient for advancing, after arriving between the first circular groove and the second circular groove etc. circular compression bar, can hold out against again the first circular groove and the second circular groove, easier for installation in the situation that not reducing sealing effectiveness.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model bridge extension joint;
Fig. 2 is the structural representation of waterstop;
Fig. 3 is the structural representation of shaped steel.
The specific embodiment
Below in conjunction with accompanying drawing, the structure of the utility model bridge extension joint and use principle are described in further details.
As shown in Figure 1, Figure 2 and Figure 3, the utility model bridge extension joint, comprise anchor bar 9, the waterstop 4 with the shaped steel 2 of draw-in groove 1 and two ends with card article 3, card article 3 is stuck in draw-in groove 4, in the upper end of draw-in groove 1, be provided with the first circular groove 5, in card article 3 upper ends, be provided with the second circular groove 6, between the first circular groove 5 and the second circular groove 6, be provided with circular compression bar 7.When mounted, the card article of waterstop 43 is inserted in draw-in groove 1, then by circular compression bar 7, by manipulator, the upper end along card article 3 is allocated between the first circular groove 5 and the second circular groove 6 to both sides, and circular compression bar 7 is stuck in the first circular groove 5 and the second circular groove 6 tightly.Avoided card article 3 to deviate from from draw-in groove 1, and between circular compression bar 7 and the first circular groove 5 and the second circular groove 6, be face sealing, sealing effectiveness is better, in installation and Renewal process, circular compression bar advances and is more prone to, can not cause poorly sealedly because of the twisting of circular compression bar, install and change more convenient, in the situation that not breaking off a friendship, just can change.
In circular compression bar 7 with along the axial cavity 8 of card article, by in circular compression bar 7 progradations, cavity 8 can become ellipse, highly can reducing up and down of circular compression bar 7, be more convenient for advancing, after between circular compression bar 7 arrival the first circular grooves 5 and the second circular groove 6, can hold out against again the first circular groove 5 and the second circular groove 6, easier for installation in the situation that not reducing sealing effectiveness.
Protection domain of the present utility model is not only confined to above-described embodiment, as long as the structure of structure and the utility model bridge extension joint is same or similar, just drops on the scope of the utility model protection.
