Description

High-durability assembling sidewalk system
Technical field
The present invention relates to the sidewalk step plate and the supporting structure thereof of bridge engineering.
Background technology
The sidewalk system is the main ancillary facility of bridge construction.Existing sidewalk system goes on foot plate, sidewalk support and pedestrian guard rail post by the sidewalk and forms, its sidewalk step plate is made by ordinary reinforced concrete, its sidewalk support is a steel bracket, therefore, there are poor durability, easy to crack, problem such as corrosion resistance is poor, anti-local assault weight bearing power is low, frangibility, maintenance workload are big.Existing sidewalk member dead weight has also increased the burden of main body load-carrying members greatly.
Summary of the invention
Existing ordinary reinforced concrete sidewalk step plate is easy to crack in order to overcome, the shortcoming of frangibility and steel bracket resistant to rust, anti-fiery ability, the invention provides a kind of high-durability assembling sidewalk system.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of high-durability assembling sidewalk system, comprise: sidewalk step plate, sidewalk support and pedestrian guard rail post, it is characterized in that: sidewalk support, sidewalk step plate and pedestrian guard rail post, except that the bottom of pedestrian guard rail post is provided with a structure muscle, principal rod all is not set in the member, makes by RPC fully; The sidewalk support Design is hollow triangular plate ribbed structure in the middle of becoming; In the middle of being designed to, sidewalk step plate is hollow plank frame; The pedestrian guard rail post is designed to the square-section form, and the bottom is provided with a structure muscle.
Beneficial effect of the present invention:
(1) adopts the material of RPC, guaranteed high-durability of the present invention as high-durability assembling sidewalk system.This kind material has high-durability, dynamic modulus of elasticity free of losses, the quality free of losses of 600 quick freeze thawing resistance test RPC test specimens; Impermeability illustrates that greater than P16 its impermeability is fairly good, and the benefit of bringing is the intrusion that has stoped hazardous medium effectively.The compressive strength of this kind material reaches 180MPa, and tensile strength reaches 20MPa.
(2) sidewalk step plate adopts the thin-walled hollow structure, and support adopts the hollow triangle structure, reaches the purpose of rationally utilizing this kind mechanical properties of materials.
(3) sidewalk step plate and internal stent all are not provided with reinforcing bar, and all shear stress and tensile stresss are born separately by RPC.The problem that does not have corrosion of steel bar is easy to building and moulding of sidewalk step plate and support.
(4) sidewalk step plate and support adopt prefabrication, the form of construction work of on-site consolidation.Prefabrication helps ensuring the quality of products stable; Batch process helps raising speed, reduces production costs.
(5) sidewalk step plate and support require to reach stream curing or the hot water maintenance that is not less than 70 ℃, and the concrete component factory that this curing condition is general all can realize.

Among the figure: sidewalk support 1, sidewalk step plate 2, pedestrian guard rail post 3, bridge main body structure 4, U-bolt 5, mastic asphalt 6, hollow triangle 7, rib 8, supporting plate 9, spacing rib 10, hollow parts 11, hole 12, epoxy mortar 13, structure muscle 14, pit a.
The specific embodiment
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a high-durability assembling sidewalk system, and it comprises: sidewalk support 1, sidewalk step plate 2 and pedestrian guard rail post 3.A sidewalk support 1 and pedestrian guard rail post 3 are set, laying sidewalk step plate 2 between per two sidewalk supports 1 every 1.5 meters.When pedestrian guard rail post 3 is connected with the end of sidewalk support 1, see Fig. 7, the bottom of pedestrian guard rail post 3 is inserted among the pit a of support 1 end, sidewalk, fill with epoxy mortar 13 plugs around it; In the hole 12 on pedestrian guard rail post 3, the sidewalk handrail is installed.The sidewalk system connects by the U-bolt 5 that is embedded in Φ 20 in the bridge main body structure 4.
The operating principle of sidewalk system is: sidewalk step plate 2 is passed to sidewalk support 1 with the vertical load that bears; Pedestrian guard rail post 3 is passed to sidewalk support 1 with horizontal loading; Sidewalk support 1 passes to bridge main body structure 4 with level and vertical load.
Fig. 2 is a sidewalk support 1, and it is made by RPC fully, and principal rod is not set, and is convenient to the casting of sidewalk support 1, does not have the corrosion problem of steel bar stress in the ordinary reinforced concrete.Be hollow 7 triangular supports plate 9, rib 8 formula structures in the middle of sidewalk support 1 is designed to, purpose is to make full use of RPC material tension, mechanical characteristic that compressive strength is high.
Fig. 4 is a sidewalk step plate 2, and it is made by RPC fully, and any reinforcing bar is not set, so that the sidewalk goes on foot the casting of plate 2, does not have the corrosion problem of reinforcing bar in the ordinary reinforced concrete.Be hollow 11 plank frame in the middle of sidewalk step plate 2 is designed to, purpose is to make full use of RPC material tension, mechanical characteristic that compressive strength is high.For not producing bigger suitable bridge between guarantor trade step plate 2 and the sidewalk support 1, designed the outstanding spacing rib 10 of twice in the end of sidewalk step plate 2 to relatively moving.The direction across bridge of plate 2 moves for the guarantor trade step, and between sidewalk step plate 2, plug is filled out mastic asphalt 6.
Fig. 6 is a sidewalk baluster 3, is made by RPC fully, and its bottom is provided with outside the structure muscle 14, other reinforcing bar is not set, so that the casting of pedestrian guard rail post 3.Structure muscle 14 is selected the reinforcing bar of Φ 18 for use.Pedestrian guard rail post 3 is designed to the square-section form, and purpose is to make full use of RPC material tension, mechanical characteristic that the pressure degree is high.Pedestrian guard rail post 3 is provided with the circular hole 12 of Φ 24, is used for installing the galvanizing steel of Φ 20 as pedestrian guard rail.
Fig. 7 is a sidewalk baluster 3 and being connected of sidewalk support 1.Pedestrian guard rail post 3 is inserted among the pit a of support 1 end, sidewalk, adopt epoxy mortar 13 to fill all around and get final product.
