Abstract
The utility model discloses a kind of prefabricated road surface of assembled steel reinforced concrete hollow.Be provided with one group of tubing 2 arranged in parallel in described prefabricated road surface 1, be provided with one group of rectangle reinforcing steel bar frame 3 outside tubing 2, rectangle reinforcing steel bar frame 3 is uniform along tubing 2 length direction; The upper muscle 4 of one group of rectangle reinforcing steel bar frame 3 is connected through one group of longitudinal reinforcement 6 respectively with lower muscle 5; Every root tubing 2 both sides are equipped with one group of positioning bar 7, and positioning bar 7 two ends are connected with the upper muscle 4 of rectangle reinforcing steel bar frame 3 and lower muscle 5 respectively.The utility model alleviates plate body weight, reduces cost of transportation and construction dismounting difficulty, saves material, and then significantly reduce use cost.Save the expense of temporary pavement.
Description
Technical field
the utility model relates to a kind of prefabricated road surface of assembled steel reinforced concrete hollow, belongs to temporary road laying technology field, building site.
Background technology
on-the-spot in building site, usually can at laying temporary road to meet traffic requirements, the cast-in-place road surface of the many employings of existing temporary road, cast-in-place road surface is permanent road, is difficult to remove, so directly abandoned after completion of works.The road abandoned will become useless building waste, cause the waste of resource, also disagree with the target of China energy-saving and emission-reducing.
in order to reduce the building waste that road is formed, the road of some building site tries to adopt reinforced concrete prefabricated road surface, be spliced into temporary road, when reinforced concrete prefabricated road surface being removed after completion of works, reinforced concrete prefabricated road surface after dismounting can also be reused in other building site, effectively decrease the waste of resource and the generation of rubbish, improve the economic and social benefits.Existing precast concrete temporary pavement plate mostly is solid slab, waste material, and plate body weight is large, make and cost of transportation high, installing/dismounting difficulty of construction is large.In this case, adopt the hollow temporary pavement plate of prefabricated assembling type reinforced concrete, alleviate plate body weight, reduce cost of transportation and construction dismounting difficulty, save material, and then use cost is significantly reduced.
Utility model content
the purpose of this utility model is, provides a kind of prefabricated road surface of assembled steel reinforced concrete hollow, adopts prefabricated assembling type reinforced concrete hollow temporary pavement plate, can lightened plate floor body weight, reduces and makes and cost of transportation, simplify construction dismounting difficulty, save material.To make up the deficiencies in the prior art.
the technical solution of the utility model:
a kind of prefabricated road surface of assembled steel reinforced concrete hollow, be provided with one group of tubing arranged in parallel in described prefabricated road surface, be provided with one group of rectangle reinforcing steel bar frame outside tubing, rectangle reinforcing steel bar frame is uniform along pipe length direction; The upper muscle of one group of rectangle reinforcing steel bar frame is connected through one group of longitudinal reinforcement respectively with lower muscle; Every root tubing both sides are equipped with one group of positioning bar, and positioning bar two ends are connected with the upper muscle of rectangle reinforcing steel bar frame and lower muscle respectively.
in the aforementioned prefabricated road surface of assembled steel reinforced concrete hollow, described longitudinal reinforcement and positioning bar two ends are equipped with crotch, and outermost two the rectangle reinforcing steel bar frame hooks of the crotch at longitudinal reinforcement two ends and prefabricated road surface connect; The crotch at positioning bar two ends connects with the upper muscle of rectangle reinforcing steel bar frame and lower muscle hook respectively.
in the aforementioned prefabricated road surface of assembled steel reinforced concrete hollow, the external diameter φ of described tubing is 0.5l ~ 0.8l times of prefabricated road surface thickness B; Gap S between two tubing is 0.25l ~ 0.1l times of prefabricated road surface thickness B.
in the aforementioned prefabricated road surface of assembled steel reinforced concrete hollow, described tubing is steel pipe or glass reinforced plastic pipe.
compared with prior art, the utility model alleviates plate body weight, reduces cost of transportation and construction dismounting difficulty, saves material, and then significantly reduce use cost.Save the expense of temporary pavement.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is sectional schematic diagram of the present utility model.
the prefabricated road surface of being labeled as in accompanying drawing: 1-, 2-tubing, 3-rectangle reinforcing steel bar frame, the upper muscle of 4-, muscle under 5-, 6-longitudinal reinforcement, 7-positioning bar, 8-crotch.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
Embodiment
a kind of prefabricated road surface of assembled steel reinforced concrete hollow, as shown in Figure 1: be provided with one group of tubing 2 arranged in parallel in described prefabricated road surface 1, be provided with one group of rectangle reinforcing steel bar frame 3 outside tubing 2, rectangle reinforcing steel bar frame 3 is uniform along tubing 2 length direction; The upper muscle 4 of one group of rectangle reinforcing steel bar frame 3 is connected through one group of longitudinal reinforcement 6 respectively with lower muscle 5; Every root tubing 2 both sides are equipped with one group of positioning bar 7, and positioning bar 7 two ends are connected with the upper muscle 4 of rectangle reinforcing steel bar frame 3 and lower muscle 5 respectively.Tubing 2 accurate positioning can be ensured by positioning bar 7, can not on the make off normal, on the other hand can control panel body thickness, make whole plate body thin and thick consistent.Longitudinal reinforcement 6 and positioning bar 7 two ends are equipped with crotch 8, and the crotch 8 at longitudinal reinforcement 6 two ends connects with outermost two rectangle reinforcing steel bar frame 3 hooks in prefabricated road surface 1; The crotch 8 at positioning bar 7 two ends connects with the upper muscle 4 of rectangle reinforcing steel bar frame 3 and lower muscle 5 hook respectively.Tubing 2 is steel pipe or glass reinforced plastic pipe.As shown in Figure 2, the external diameter φ of tubing 2 is 0.5l ~ 0.8l times of prefabricated road surface 1 thickness B; Gap S between two tubing 2 is 0.25l ~ 0.1l times of prefabricated road surface 1 thickness B.
