Abstract
A bridge stone handrail protecting device is formed by splicing two stainless steel brackets of the same structure. A rail post sleeve plate is arranged between the stainless steel brackets. Handrail sleeve plates are arranged at the two ends of the rail post sleeve plate. A buckling plate is arranged at the upper end of the rail post sleeve plate. A supporting plate is arranged at the lower end of each handrail sleeve plate, and a protecting plate is arranged at the upper end of each handrail sleeve plate. A connecting plate is arranged at the joint of the two stainless steel brackets. The buckling plate, the supporting plates, the protecting plates, the rail post sleeve plate, the handrail sleeve plates and the connecting plate are all connected into a whole. A connecting hole is formed in the connecting plate. The two stainless steel brackets are connected through bolts or rivets. By means of the bridge stone handrail protecting device, the supporting face of a stone handrail is enlarged, the force borne by tenon of the handrail is reduced, and the tenon of the handrail can be effectively prevented from breaking and falling; the bridge stone handrail protecting device is formed by splicing the two stainless steel brackets, and is easy and convenient to operate and high in construction speed; the problem that the tenon of the stone handrail is prone to breakage is solved, and the engineering cost for replacing a bridge rail is saved, and the economic effect is remarkable; the force bearing capacity of the stone rail is optimized, and the application range of the stone rail is widened.
Description
Technical field
The present invention relates to a kind of safety guard for preventing bridge stone material handrail from dropping because of dovetail break between baluster, especially a kind of bridge stone material handrail protective device.
Background technology
Stone material is the traditional material and so far still in a large amount of use of constructing a bridge of China, stone railing more because of its there is simple and unsophisticated attractive in appearance, environmental protection, the anti-aging advantage such as indeformable is widely used.In order to coordinate, reflect rhythm at the bottom of the strong traditional culture of China with surrounding landscape, the bridge on highway and urban road also often selects stone railing.Stone railing is assembled by baluster, handrail, the flower stone component such as version, support, is connected between each component by fluting and tenon.Because stone material is fragile material, therefore fluting and the tenon degree of depth are all unsuitable excessive, and the tenon degree of depth of general handrail is only 30 ~ 50mm, short and stressed weakness.
Generally can there is handrail and baluster joint dovetail break in current bridge stone railing, and then drop, both affected attractive in appearance more jeopardize the current safety of pedestrian, vehicle, its Producing reason be light-duty superstructure bridge (as beam bridge, slab bridge) automobile by time can produce larger vertical motion, the essence of this vertical motion is the distortion that downwarp, arch occur superstructure beam slab repeatedly, and now stone railing followed by distortion.And stone railing is a kind of fragile material, be not suitable with this vibration, due to handrail apart from beam slab farthest, the frictional resistance that handrail tenon is subject to because inter-baluster constantly changes and vibration also maximum, therefore most easy fracture.
Summary of the invention
The object of this invention is to provide a kind of structure simple, install convenient, cost is low, result of use good, can prevent the bridge stone material handrail protective device of stone material hand rail intercolumniation dovetail break.
Bridge stone material handrail protective device of the present invention, it is characterized in that, it is spliced by the stainless steel brackets that two chip architectures are identical, it is baluster cage plate in the middle part of stainless steel brackets, two ends are handrail cage plate, the upper end of baluster cage plate is provided with buckle, supporting plate is established in the lower end of handrail cage plate, upper end is backplate, two panels stainless steel brackets joint, namely the side of baluster cage plate and the backplate of handrail cage plate are provided with junction plate, junction plate has connecting hole, backplate buckle, supporting plate, backplate, baluster cage plate, handrail cage plate, junction plate is all connected as a single entity, two panels stainless steel brackets is inserted connecting hole by bolt or rivet and is connected.
Bridge stone material handrail protective device of the present invention; the stainless steel brackets fitted with railing style is set up in the baluster of bridge, handrail junction; to hold stone material handrail; reduce handrail tenon stressed; prevent stone material handrail from rupturing and dropping; for adapting with stone railing color and luster, mode changes stainless steel brackets surface color can to adopt plastic-blasting or spray paint etc., or directly adopts stainless steel component true qualities to realize fashion and traditional unification.It has the following advantages:
1, increase the supporting surface of stone material handrail, reduce handrail tenon stressed, effectively can prevent handrail dovetail break and drop.2, assembled by two panels stainless steel brackets, easy and simple to handle, speed of application is fast.3, pass through at stainless steel brackets surface plastic spraying, spray paint or adopt stainless steel material true qualities, make bridge railing more attractive in appearance.4, solve the problem of stone material handrail tenon easy fracture, save the engineering cost changing bridge railing, obvious economic.5, optimize the stress performance of stone railing, solve because it belongs to the problem that friable structure is not suitable for light-duty superstructure bridge, expand the scope of application of stone railing.
