Abstract
The utility model relates to a ground elastic expansion joint structure which comprises concrete plates, expansion joints reserved among the plates, a mortar layer and a ground pavement layer. Support plates are arranged in the expansion joints among the concrete plates, the support plates are fixed with the concrete plates through bolts, bolts arranged on the support plates are bar-shaped, and nut caps matched with the bolts and the bolt holes are arranged above the rectangular bolt holes. Gaps are reserved at two sides of the mortar layer arranged above the support plates and the ground pavement layer, and the gaps are filled with foam bars and elastic seal gum. The structure can support a ground and prevent the ground from collapsing, the bolt holes are bar-shaped so enough expansion spaces are reserved for the bolts, the bolts fixed on the concrete plates can move in the bar-shaped bolt holes when expansion and deformation of the structure happen, and therefore the support plates cannot move and move of the mortar layer and the ground pavement layer above the support plate can also be prevented, loosening of the mortar layer and the ground pavement layer can be prevented to avoid the occurrence of cracks, and the ground can be beautiful, solid and not easy to damage.
Description
Technical field
The utility model relates to a kind of seam construction, especially ground elastic expansion joint structure.
Background technology
Super long building is pressed code requirement because structural span is large, and structure expansion joint generally all should be established in its ground, and architectural surface also should disconnect at the structure expansion joint place, can be out of shape with structure, but this can affect the impression quality of decorative cover and use function.
Chinese utility model patent CN 201460145 U disclose a kind of expanded joint structure, between concrete, be equipped with the corrosion resistant plate of protuberance in the shrinkage joint, the decorative layer distortion of expanding with heat and contract with cold in ground will be delivered on the corrosion resistant plate like this, corrosion resistant plate top ridges when temperature raises, when drop in temperature shrinks, restore to the original state.But use the prefabricated corrosion resistant plate can't be with the condition adjustment of job site height.The steel plate thickness of this structure can not be too large, and the bearing capacity of the steel plate that thickness is less is also less.When temperature raise, the plate of both sides expanded, and pressing steel plate makes it protuberance, and steel plate can produce stress, and plate is produced extruding, easily causes the plate margin impaired, affects outward appearance and the life-span of architectural surface.
Chinese utility model patent CN 202125055 U disclose a kind of expansion joint structure of indoor floor block veneer, comprise the isolation channel and its inboard many affixed reinforcing ribs that are arranged between concrete surface two plates, pour into respectively elastic sealant in the slit between isolation channel two outsides and plate, this structure can effectively prevent subsiding of ground, place, shrinkage joint, but because concrete plate and reinforcing rib do not have bolt to fix, when concrete plate varies with temperature and is out of shape, relatively moving can appear in reinforcing rib and concrete slab interblock, can cause reinforcing rib and its upper part to occur loosening, easily make reinforcing rib and this part and surface separation above it.
The utility model content
The technical problems to be solved in the utility model provides a kind of expanded joint structure that effectively prevents the malformation that causes because expanding with heat and contract with cold, and this expanded joint structure is firm, makes ground attractive in appearance, and the life-span is long.
For solving the problems of the technologies described above, ground of the present utility model elastic expansion joint structure, comprise concrete plate, the shrinkage joint of reserving between plate, screed, the ground pavement layer arranges gripper shoe at the shrinkage joint of concrete slab interblock, gripper shoe and concrete plate are fixed with bolt, and the bolt hole on the gripper shoe is strip.
The block that the top setting of rectangle bolt hole and bolt and bolt hole are complementary.
The slit is left, filled and process rod and elastic sealant in the slit in screed and the ground pavement layer both sides of described gripper shoe top.Put up the high-strength abrasion-proof warning tape on the slit of ground pavement layer.
Gripper shoe is preferably and is steel plate.
In the surface expansion joint back-fire relief band can be set under the gripper shoe.
After adopting such structure, owing at the shrinkage joint of concrete slab interblock gripper shoe being set, can effectively supporting ground and not subside.Owing in gripper shoe the strip bolt hole being set, reserve enough extendable rooms to bolt, on bolt top block is set, when the structure dilatation, the bolt that is fixed on the concrete plate can move with block is interior by the strip bolt hole, can not make the gripper shoe activity, thereby can not make screed above the gripper shoe and ground pavement layer movable yet, prevent effectively that screed and ground pavement layer are loosening and the crack occurs, so that ground is attractive in appearance, firmly, not fragile.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the sectional drawing of the utility model ground elastic expansion joint structure;
Fig. 2 is the top view of the gripper shoe of the utility model ground elastic expansion joint structure.
The specific embodiment
As depicted in figs. 1 and 2, ground of the present utility model elastic expansion joint structure, comprise concrete plate 1, the shrinkage joint 2 of 1 reservation of plate, screed 3, ground pavement layer 4, shrinkage joint 21 of concrete plate arranges supporting steel plate 5, and supporting steel plate 5 is fixing with concrete plate 1 usefulness bolt 6, and bolt hole 7 is set on the supporting steel plate 5, bolt hole 7 is strip, and the top of rectangle bolt hole 7 arranges the block 13 that is complementary with bolt 6 and bolt hole 7.Slit 8 is left in the screed 3 of supporting steel plate 5 tops and ground pavement layer 4 both sides, slit 8 interior filled and process rod 9 and elastic sealants 10.Put up high-strength abrasion-proof warning tape 11 on the slit of ground pavement layer.Arrange in 5 times surface expansion joints 2 of supporting steel plate and lead back-fire relief band 12.
When concrete plate 1 deforms, bolt 6 will produce relative motion with supporting steel plate 5, because bolt hole 7 is strips, and on bolt top block 13 is set, bolt 6 can not drive supporting steel plate 5 and move, thereby can not cause the structure above the supporting steel plate 5 to occur loosening.
The above, only be to preferred embodiment of the present utility model, be not that the utility model is done other forms of restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equal variation.Every the utility model scheme content that do not break away from, all drops in protection scope of the present invention any simple modification, equivalent variations and remodeling that above embodiment does according to technical spirit of the present invention.
