Technical Field
The utility model relates to a ground bearing expansion joint.
Background
The expansion joint is in order to satisfy the deformation needs in order to realize freely stretching out and drawing back. The expansion joint usually adopts two parallel structures to splice among the prior art, and bearing performance is general to not possess an excellent stable support function, and the seepage phenomenon appears very easily, influences the normal use of expansion joint.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a simple structure, reasonable, reliable, splices through adopting the fishback in the expansion joint both sides, and adopts corrosion resistant plate to support in the slip side for guarantee the flexible in-process sliding stability of expansion joint, in order to guarantee the ground bearing expansion joint of normal use.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a ground bearing expansion joint, which is arranged on the expansion joint on the ground and comprises a comb plate, a stainless steel plate and a water stop belt, wherein a first limit groove and a second limit groove are respectively arranged at two sides of the expansion joint on the ground in a concave manner, the depth of the second limit groove is larger than that of the first limit groove, the water stop belt is laid in the first limit groove and the second limit groove, the stainless steel plate is arranged in the second limit groove to ensure that the top of the stainless steel plate is flush with the first limit groove, the comb plate comprises a movable comb plate and a fixed comb plate, the movable comb plate is arranged in the first limit groove, the end part side of the movable comb plate is fixed by a steel expansion bolt, the tooth surface end of the movable comb plate is correspondingly arranged above the non-steel plate in the second limit groove, the fixed comb plate is arranged above the stainless steel plate in the second limit groove and is fixed by the steel expansion bolt, the tooth surface end of the fixed comb plate is meshed with the tooth surface end of the movable comb plate.
In a preferred embodiment of the present invention, the water stop is loosely disposed in the expansion joint.
In a preferred embodiment of the present invention, the water stop is an epdm water stop.
In a preferred embodiment of the present invention, the surface of the comb plate is coated with an epoxy zinc-rich anti-corrosive paint.
The utility model has the advantages that: the utility model has the advantages of simple and reasonable structure, reliable splices through adopting the fishback in the expansion joint both sides, and adopts corrosion resistant plate to support in the slip side for guarantee the flexible in-process sliding stability of expansion joint, in order to guarantee normal use.
Drawings
FIG. 1 is a top view of a preferred embodiment of the ground bearing expansion joint of the present invention;
fig. 2 is a sectional view taken along the plane a-a of fig. 1.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1 and fig. 2, an embodiment of the present invention includes: the utility model provides a ground bearing expansion joint, sets up on the expansion joint 1 on ground, includes fishback, corrosion resistant plate 2 and waterstop 3.
Wherein, 1 both sides at the expansion joint on ground are provided with first spacing groove 4 and second spacing groove 5 of indent respectively for install the fishback.
The degree of depth size of second spacing groove 5 is greater than the degree of depth size of first spacing groove 4, it has 3 just to have laid the waterstop in first spacing groove 4 and the second spacing groove 5 the waterstop 3 is lax setting in expansion joint 1 for expansion joint 1 can not cause the tensioning to damage waterstop 3 at flexible in-process. The water stop adopts an ethylene propylene diene monomer water stop, has excellent weather resistance and corrosion resistance, is used for ensuring the integral waterproofness of the first limiting groove and the second limiting groove, and has long service life. Be provided with corrosion resistant plate 2 in the second spacing groove 5 and make corrosion resistant plate 2's top and first spacing groove 4 keep flushing the setting, the stable sliding support of fishback of being convenient for.
The surface of the comb tooth plate is sprayed with epoxy zinc-rich anticorrosive paint, so that the corrosion resistance is improved, and the service life is prolonged. The fishback is including activity fishback 6 and fixed fishback 7, activity fishback 6 sets up in first spacing groove 4 and the tip side is fixed through steel expansion bolts 8, the flank end of activity fishback 6 corresponds sets up in stainless steel 2 tops of second spacing groove 5, fixed fishback 7 sets up in stainless steel 2 tops of second spacing groove 5 and fixes through steel expansion bolts 8, the flank end of fixed fishback 7 meshes with the flank end of activity fishback 6 mutually, and when the flexible phenomenon takes place in the section both sides, the flank end of activity fishback 6 is close to or keeps away from fixed fishback 7, and activity fishback 6 is in the stable slip of 4 tops of stainless steel, does not influence the normal use of fishback upper surface.
The utility model relates to a ground bearing expansion joint, the utility model has the advantages of simple structure, reasonable, reliable, splice through adopting the fishback in the expansion joint both sides, and adopt corrosion resistant plate to support in the slip side for guarantee the flexible in-process sliding stability of expansion joint, in order to guarantee normal use.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
