Abstract
The utility model discloses a kind of pavement expansion gap devices of temporary construction suspension bridge, pavement is followed successively by prefabricated side walk slab, cement sand bed and colorful surface layer from top to bottom, expansion joint is provided among pavement, expansion joint interior bottom portion is provided with aluminium sheet, aluminium sheet extends to expansion joint opposite side from expansion joint side, the both ends of aluminium sheet are fixed by screws in build-in in the pre-buried wooden unit in prefabricated side walk slab respectively, it is filled in aluminium sheet in expansion joint with pitch loose hemp fiber, pitch loose hemp fiber top is blocked with galvanized iron sheet, then blocks expansion joint with mortar；The utility model is simple in structure, and filler is not easily to fall off, sound construction, while structure Free Transform is met, it can prevent rainwater and rubbish soil from penetrating into and stopping up, be easily installed, overhaul, conserve, remove sundries, cost is relatively low simultaneously, meets the use demand of temporary structure.
Description
Technical field
The utility model is related to building engineering field, the pavement expansion joint dress of more particularly to a kind of temporary construction suspension bridge
It puts.
Background technology
With the continuous development of urbanization progress, city incity space is less and less, and urbanization process then loses and slows down,
In particular with being on the increase for various skyscrapers and underground rail engineering, need to be constructed accordingly in the underground space
It builds, but is limited by the limitation of surrounding ambient, road equipment various aspects, it has to set up corresponding temporary construction suspension bridge
To meet the life requirement of resident and garage's various aspects.To ensure suspension bridge structure in temperature Change, live loading, concrete shrinkage
With creep etc. under the influence of can Free Transform, then need to set corresponding expansion joint on the pavement of suspension bridge and driveway.Traditional
The problems such as pavement deformation joint easily comes off there are filler, structure cracky.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of pavement of temporary construction suspension bridge to stretch
Contracting seam device, what the technical solution of the pavement expansion gap device of the temporary construction suspension bridge was realized in：
A kind of pavement expansion gap device of temporary construction suspension bridge, pavement be followed successively by from top to bottom prefabricated side walk slab,
Cement sand bed and colorful surface layer are provided with expansion joint among the pavement, and the expansion joint interior bottom portion is provided with aluminium sheet,
The aluminium sheet extends to expansion joint opposite side from expansion joint side, the both ends of the aluminium sheet be fixed by screws in respectively build-in in
It in pre-buried wooden unit in prefabricated side walk slab, is filled in the aluminium sheet in the expansion joint with pitch loose hemp fiber, on the pitch loose hemp fiber
Portion is blocked with zinc-iron skin, then blocks expansion joint with mortar.
Further, the pre-buried wooden unit is disposed on expansion joint both sides.
Further, the cement sand bed uses M10 cement mortar.
Further, institute's expansion joint width is 8~10m.
The pavement expansion gap device of the utility model is simple in structure, and filler is not easily to fall off, sound construction, is tied meeting
While structure Free Transform, it can prevent rainwater and rubbish soil from penetrating into and stopping up, be easily installed, overhaul, conserve, remove sundries,
Cost is relatively low simultaneously, meets the use demand of temporary structure.
Description of the drawings
Fig. 1 is the utility model expansion gap device overall structure diagram.
Reference numeral：The prefabricated side walk slabs of 1-, 2- cement sand beds, 3- colorful surface layers, 4- expansion joints, 5- aluminium sheets, 6- are pre-
Wooden unit processed, 7- pegs, 8- mortars, 9- zinc-iron skins, 10- pitch loose hemp fibers.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of pavement expansion gap device of temporary construction suspension bridge, pavement is followed successively by prefabricated from top to bottom
Side walk slab 1, cement sand bed 2 and colorful surface layer 3, are provided with expansion joint 4 among the pavement, inside the expansion joint 4
Bottom is provided with aluminium sheet 5, and the aluminium sheet 5 extends to 4 opposite side of expansion joint, the both ends difference of the aluminium sheet 5 from 4 side of expansion joint
Build-in is fixed in the pre-buried wooden unit 6 in prefabricated side walk slab 1 by screw 5, the interior drip of aluminium sheet 5 in the expansion joint 4
10 filling of piemarker wadding, the 10 top zinc-iron skin 9 of pitch loose hemp fiber blocks, then blocks expansion joint 4 with mortar 8.
When it is implemented, the pre-buried wooden unit 6 is disposed on 4 both sides of expansion joint.
When it is implemented, the cement sand bed 2 uses M10 cement mortar.
When it is implemented, 4 width of institute expansion joint is 8~10m.
The technology contents and technical characteristic of the utility model have revealed that as above those skilled in the art still may base
The replacement and modification without departing substantially from the utility model in essence are made in the teaching of the utility model, therefore, the utility model protection
Range is not limited to the revealed content of embodiment, also including various replacements and modification without departing substantially from the utility model in essence.
