Abstract
The invention discloses an arrangement method for dowel bars of a cement-concrete pavement. During construction at a construction joint, the method that sleeves are pre-buried in a formwork and then the dowel bars are placed in the later period is adopted. Each pre-buried sleeve is a PVC pipe which is one specification larger than the dowel bars in diameter, and reinforcing steel bar supports are arranged on the lower portions of the PVC pipes. The two ends of each PVC pipe are blocked through adhesive tape. After pouring of concrete on one side of the construction joint is completed, the formwork and the blocking adhesive tape of the PVC pipes are dismounted, asphalt paste is poured into the PVC pipes, the dowel bars are plugged in, and pavement concrete is poured. According to the method that the PVC sleeves are pre-buried and then the dowel bars are placed in the later period, the step of drilling holes in the formwork is omitted, the formwork is dismounted conveniently and rapidly, the integrity of the formwork is kept, and the number of circulating using times of the formwork is increased; in the dismounting process of the formwork, manpower is saved, and the construction period is shortened; and high economical efficiency and applicability are achieved.
Description
Technical field
The present invention relates to a kind of constructing method for cement concrete road surface, especially relate to a kind of cement concrete pavement and pass
Power bar method to set up.
Background technology
The dowel steel setting of construction of cement concrete road surface seam at present adopts mostly inserts dowel steel after jewel hole in template
Method, the template of concrete road surface adopts steel form mostly.Because bad fixation between dowel steel and template, in work progress
Personnel, equipment all very likely cause dowel steel level or vertical off normal, if causing off normal, for channel-section steel template it is impossible to directly
Form removal, can remove after needing to correct dowel steel step by step, and it is longer, laborious to remove the time；For plank sheathing, then can
Directly damage template.
Content of the invention
In order to solve the problems of the prior art, the present invention provides a kind of dowel bars into cement concrete pavement method to set up,
Solve the problems, such as in prior art bad fixation between dowel steel and template and to remove the time longer, laborious.
The technical scheme is that：A kind of dowel bars into cement concrete pavement method to set up, when constructing at construction joint, adopts
With first embedded sleeve barrel in template, then the method that the later stage puts into dowel steel.
Described embedded sleeve barrel is the pvc pipe of big 1 specification than power transmission shank diameter, and pvc pipe bottom arranges Steel bar rack.?
The two ends of pvc pipe adopt adhesive tape to block, the closure glue of form removal and pvc pipe after the completion of side concreting at construction joint
Band, pours into Colophonium ointment in pvc pipe, then fills in dowel steel, pour pavement concrete.
The invention has the beneficial effects as follows：A kind of first pre-buried PVC sleeve of the present invention, then the method that the later stage puts into dowel steel,
The step eliminating jewel hole in template, convenient during form removal, save the integrity of template, the turnover that improve template makes
With number of times, and save the artificial and duration during form removable, there is larger economy and the suitability.
Brief description
Fig. 1：Dowel steel method to set up schematic diagram of the present invention；
Wherein：1- template；2-PVC sleeve pipe；3- Steel bar rack.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further details.
Concrete dowel steel is arranged at the T-joining of cement concrete pavement, and T-joining comprises baste type and construction joint,
The dowel steel of baste type is directly all embedded in concrete, and the dowel steel half at construction joint is in a front casting concrete
In, second half is in the concrete of rear one-time-concreting.After the completion of concrete road face die plate 1 installs, the inner side of template 1 according to
The pvc pipe 2 of the pre-buried specification bigger than power transmission shank diameter in position of dowel steel, pvc pipe 2 bottom arranges Steel bar rack 3, in PVC
The two ends of pipe 2 adopt adhesive tape to block, the closure adhesive tape of form removal and pvc pipe after the completion of side concreting at construction joint,
Pour into Colophonium ointment in pvc pipe, then fill in dowel steel, pour pavement concrete.
The foregoing is only presently preferred embodiments of the present invention, protection scope of the present invention is not limited to above-mentioned case study on implementation,
All impartial changes done according to scope of the present invention patent and modification, all should belong to the covering scope of the present invention, the application is wanted
The protection domain asked is as shown in the application claims.
Claims (3)
1. a kind of dowel bars into cement concrete pavement method to set up is it is characterised in that when constructing at construction joint, using first in template
Interior embedded sleeve barrel, then the method that the later stage puts into dowel steel.
2. according to claim 1 dowel bars into cement concrete pavement method to set up it is characterised in that described embedded sleeve barrel is
The pvc pipe of big 1 specification than power transmission shank diameter, pvc pipe bottom arranges Steel bar rack.
3. according to claim 2 dowel bars into cement concrete pavement method to set up it is characterised in that two ends in pvc pipe
Using adhesive tape closure, the closure adhesive tape of form removal and pvc pipe after the completion of side concreting at construction joint, in pvc pipe
Pour into Colophonium ointment, then fill in dowel steel, pour pavement concrete.
