Description

Technical Field

[0001] The utility model relates to the technical field of bridge decks, in particular to an ultra-high performance concrete anti-skid bridge deck. Background Art

[0002] The bridge deck structure is a critical component of bridge design. The deck directly bears vehicle loads and transmits these loads to the main beams. Ultra-high performance concrete (UHPC) is a high-strength, highly durable, highly tough, and dense concrete material that uses fine sand as an aggregate instead of coarse aggregate. It incorporates large amounts of mineral admixtures such as silica fume, high-efficiency water reducers, and fine steel fibers. Its compressive and tensile strengths are far superior to those of ordinary concrete, making it a common material for bridge decks in engineering production.

[0003] The existing bridge deck has poor drainage effect in rainy weather, and vehicles are prone to slipping when driving on the bridge deck, which reduces the safety of bridge deck use. Utility Model Content

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to propose an anti-skid bridge deck that improves the drainage effect of the bridge deck, thereby reducing the probability of slippage during vehicle driving and ensuring the safety of the bridge deck.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The utility model provides an ultra-high performance concrete anti-skid bridge deck, comprising a base plate, an ultra-high performance concrete layer, a reinforced wear-resistant layer and a top plate arranged in sequence from bottom to top, an adhesive layer is provided between the reinforced wear-resistant layer and the top plate, and an anti-skid coating is provided on the top of the top plate;

[0007] The top surface of the top plate is in an arc shape, and drainage grooves are symmetrically provided on both sides of the top plate. The inner wall of the drainage groove is provided with a diversion inclined portion, and the diversion inclined portion is inclined from the side surface of the top plate toward the drainage groove.

[0008] An optimal technical solution of the present invention is that a waterproof layer is provided between the ultra-high performance concrete layer and the reinforced wear-resistant layer.

[0009] An optimal technical solution of the present invention is that a plurality of groups of drainage holes are distributed at equal intervals on the drainage groove, a drainage channel is provided on the waterproof layer, and the drainage channel is communicated with the drainage holes.

[0010] A preferred technical solution of the present invention is that the anti-slip coating is a polyurea ice-phobic coating layer.

[0011] An optimal technical solution of the present invention is that a plurality of groups of anti-slip grooves are evenly distributed on the top of the anti-slip coating layer, and the anti-slip grooves are wavy.

[0012] An optimal technical solution of the present invention is that the wave-bending portions of the plurality of anti-slip patterns are connected with anti-slip ribs.

[0013] An optimal technical solution of the present invention is that a plurality of groups of I-beams are arranged at equal intervals inside the ultra-high performance concrete layer, and a plurality of groups of reinforcing steel bars are arranged between the plurality of groups of I-beams.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model provides drainage grooves on both sides of the top plate, and cooperates with the setting of the diversion inclined part, so that rainwater can flow along the two sides of the top plate toward the drainage grooves, and then the rainwater entering the drainage grooves is discharged outward from the drainage channel through the drainage holes, avoiding the bridge deck from slipping due to accumulation of rainwater, which causes the vehicle to slip during driving. At the same time, an anti-skid coating layer of polyurea ice-repellent coating is provided, which can effectively increase the anti-skid performance of the bridge deck and increase the safety of the vehicle during driving. In addition, wavy anti-skid patterns are provided and connected by anti-skid ribs, which can effectively increase the friction of the vehicle during driving on the bridge deck, thereby reducing the probability of vehicle slipping, improving the safety of the vehicle during driving on the bridge deck, reducing the occurrence of traffic hazards, and ensuring the safety of bridge deck use.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0022] An ultra-high performance concrete anti-skid bridge deck comprises a base plate 1, an ultra-high performance concrete layer 2, a reinforced wear-resistant layer 8, and a top plate 4, which are arranged in sequence from bottom to top. An adhesive layer is provided between the reinforced wear-resistant layer 8 and the top plate 4. An anti-skid coating 5 is provided on the top of the top plate 4. The anti-skid coating 5 is a polyurea ice-repellent coating layer. A waterproof layer 3 is provided between the ultra-high performance concrete layer 2 and the reinforced wear-resistant layer 8.

[0023] The top surface of the top plate 4 is in an arc shape, and drainage grooves 6 are symmetrically provided on both sides of the top plate 4. The inner wall of the drainage groove 6 is provided with a diversion inclined portion 62, and the diversion inclined portion 62 is inclined from the side of the top plate 4 to the drainage groove 6.

[0024] When a vehicle drives onto the bridge deck in rainy weather, since the top surface of the top plate 4 is in an arc shape, rainwater will slide to the two sides of the top plate 4 and flow into the drainage ditch 6 along the guide inclined portion 62, so that the rainwater is discharged from the bridge deck, avoiding the accumulation of rainwater on the bridge deck, causing the bridge deck to become slippery, causing the vehicle to slip during driving, and affecting the driving safety of the vehicle, thereby ensuring the safety of the bridge deck. The anti-skid coating 5 of the polyurea ice-repellent coating layer can effectively increase the anti-skid performance of the bridge deck and increase the safety of the vehicle during driving.

[0025] As a possible implementation of this solution, preferably, a plurality of groups of drainage holes 61 are evenly spaced on the drainage groove 6 , and a drainage channel 63 is provided on the waterproof layer 3 , and the drainage channel 63 is connected to the drainage holes 61 .

[0026] Rainwater enters the drainage trough 6 through the diversion inclined portion 62 and flows to the drainage channel 63 through the drainage hole 61, so that the rainwater is discharged outward through the drainage channel 63, reducing the accumulation of rainwater on the bridge deck, thereby affecting the driving safety of vehicles on the bridge deck and reducing safety hazards.

[0027] As a possible implementation of this solution, preferably, a plurality of groups of anti-slip grooves 7 are evenly distributed on the top of the anti-slip coating 5, and the anti-slip grooves 7 are wavy. The wavy bends of the plurality of groups of anti-slip grooves 7 are connected with anti-slip ribs 71.

[0028] By setting up wavy anti-skid patterns 7 and connecting them through anti-skid ribs 71, the friction of the vehicle during driving on the bridge deck can be effectively increased, thereby reducing the probability of vehicle slippage, improving the safety of the vehicle during driving on the bridge deck, reducing traffic hazards, and ensuring the safety of bridge deck use.

[0029] As a possible implementation scheme of this solution, preferably, a plurality of groups of I-beams 21 are arranged at equal intervals inside the ultra-high performance concrete layer 2, and a plurality of groups of reinforcing steel bars 22 are arranged between the plurality of groups of I-beams 21. By staggering the plurality of groups of I-beams 21 and the reinforcing steel bars 22, the service strength and stability of the ultra-high performance concrete layer 2 can be effectively improved.

[0030] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application are also within the scope of protection of the present invention.
