Description

Technical Field

[0001] The utility model relates to the technical field of railings, in particular to a UHPC composite railing. Background Art

[0002] UHPC can be regarded as the engineering material with the best durability. The mechanical properties of appropriately reinforced UHPC are close to those of steel structures. At the same time, UHPC has excellent wear resistance and explosion resistance. UHPC has been applied in some practical projects, such as long-span pedestrian bridges, highway and railway bridges, thin-walled silos, steel cable anchorage reinforcement plates, etc.

[0003] The publication number is: CN207406124U, and the disclosed "UHPC composite railing with adjustable height includes a railing panel and a column connected to the railing panel; a hollow through hole is provided in the middle of the railing panel; a slot for connecting the railing panel is provided on the side wall of the column; convex platforms adapted to the slots are provided at both ends of the railing panel. The utility model has a simple structure and is easy to implement. By using UHPC material to make the railing, the on-site construction difficulty and on-site workload can be greatly reduced, and related construction procedures such as anti-corrosion, anti-erosion or anti-cavitation of related buildings can be cancelled, especially suitable for engineering fields with requirements such as corrosion resistance, anti-cavitation and wear resistance".

[0004] When in use, there are still certain drawbacks. The railing panel is installed between two columns through the slots. When the railing panel is impacted, the column only facilitates sharing the impact force received by the railing panel through the part behind the slot, and the anti-impact ability is poor. It is not convenient to share the impact force received by the railing panel through the part in front of the slot, and the railing panel is directly inserted between two columns, so the firmness is poor and it is easy to be manually moved, exacerbating the wear at the connection. Summary of the Utility Model

[0005] In order to overcome the above technical problems, the purpose of the utility model is to provide a UHPC composite railing. By passing a screw through a plurality of round holes and screwing it with a threaded hole, the railing panel and the column are fixed, so that after the railing panel is installed inside the slot, the railing panel and the column can be fixed from the lower end of the column, so as to avoid the exacerbation of wear at the connection caused by the manual movement of the railing panel. By connecting the connection ring, the connection frame, the pouring frame and the reinforcement frame, the connection frame, the pouring frame and the reinforcement frame share the impact force received by the railing panel, so as to strengthen the structural stability of the lower ends of the column and the railing panel through the fixing structure. At the same time, when the railing panel is impacted, it is convenient to use the fixing structure to make the whole part of the lower end of the column share the impact force received by the railing panel, improving the anti-impact ability of the railing panel.

[0028] Slots 101 are symmetrically formed on both side surfaces of the column 1. A plurality of through holes 102 are formed at the lower end of one side surface of the column 1. A circular groove 103 is formed on the upper surface of the column 1. A plurality of clamping blocks 107 are equidistantly and fixedly installed on the inner surface of the circular groove 103. An end cap 104 is movably arranged at the upper end of the column 1. A cylinder 105 is fixedly installed on the lower surface of the end cap 104. A plurality of F-shaped clamping grooves 106 are equidistantly formed on the outer surface of the cylinder 105. The clamping blocks 107 are slidably connected with the F-shaped clamping grooves 106. The cylinder 105 is inserted into the circular groove 103, so that the clamping blocks 107 are inserted into the lower ends of the F-shaped clamping grooves 106. Then the end cap 104 is rotated to make the clamping blocks 107 snap into one end of the F-shaped clamping grooves 106, thereby fixing the end cap 104 and improving the firmness of the end cap 104. The railing board 2 is slidably connected with the slots 101. Connecting grooves 201 are formed at the lower ends of both side surfaces of the railing board 2. The connecting frame 302 passes through the slots 101 and is slidably connected with the adjacent connecting grooves 201. The connecting frame 302 is snapped into the inner sides of the connecting grooves 201 on both sides of the railing board 2, increasing the firmness between the column 1 and the railing board 2. Connecting columns 305 are fixedly connected between the connecting frame 302, the pouring frames 303 and the reinforcing frames 304. A plurality of circular holes 306 are formed on one side surface of one pouring frame 303, the connecting frame 302 and the reinforcing frame 304. A plurality of threaded holes 307 are formed on one side surface of the other pouring frame 303. A screw rod 308 is passed through the plurality of circular holes 306 and screwed with the threaded holes 307, so that the railing board 2 and the column 1 are fixed. Thus, after the railing board 2 is installed into the slots 101, the railing board 2 and the column 1 can be fixed from the lower end of the column 1 to prevent the wear at the connection caused by the artificial movement of the railing board 2 from being aggravated.

It is also possible to pour concrete in advance on the outside of the steel bar framework 301 through a formwork, and then directly insert the formed concrete block into the installation pit. Insert the cylinder 105 into the round groove 103, so that the clamping block 107 is inserted into the lower end of the F-shaped clamping groove 106, and then rotate the end cap 104 to make the clamping block 107 snap into one end of the F-shaped clamping groove 106 to fix the end cap 104, improving the firmness of the end cap 104. The connecting frame 302 is snapped into the inner sides of the connecting grooves 201 on both sides of the railing plate 2, increasing the firmness between the column 1 and the railing plate 2. Thread the screw rod 308 through a plurality of round holes 306 and thread it with the threaded hole 307 to fix the railing plate 2 and the column 1. Thus, after installing the railing plate 2 into the slot 101, the railing plate 2 and the column 1 can be fixed from the lower end of the column 1 to prevent the wear at the connection from being aggravated due to the artificial movement of the railing plate 2. The connecting ring 4, the connecting frame 302, the pouring frame 303 and the reinforcing frame 304 are connected, so that the connecting frame 302, the pouring frame 303 and the reinforcing frame 304 share the impact force borne by the railing plate 2, thereby strengthening the structural stability of the lower ends of the column 1 and the railing plate 2 through the fixing structure. At the same time, when the railing plate 2 is impacted, it is convenient to make the whole lower part of the column 1 share the impact force received by the railing plate 2 through the fixing structure, improving the impact resistance of the railing plate 2.
