Description

Technical Field

[0001] The utility model relates to the technical field of high-performance concrete components, in particular to a UHPC high-performance concrete component. Background Technique

[0002] With the increasing expectation of people for higher performance of concrete, in the early 1990s, a new type of ultra-high performance concrete (UHPC) was developed, which has ultra-high strength (>150MPa) and excellent durability.

[0003] Chinese Patent with publication number CN216475623U discloses an ultra-high performance concrete precast component, including a first ultra-high performance concrete slab and a second ultra-high performance concrete slab. A plurality of connecting grooves are opened on both the first ultra-high performance concrete slab and the second ultra-high performance concrete slab. Pouring holes are opened on the top surfaces of the first ultra-high performance concrete slab and the second ultra-high performance concrete slab, and the pouring holes penetrate through and connect a plurality of connecting grooves. A plurality of pairs of clamping grooves are opened on one side of the first ultra-high performance concrete slab. A plurality of pairs of connecting plates are installed on one side of the second ultra-high performance concrete slab. Limiting holes are opened on the connecting plates. The connecting plates are clamped in the clamping grooves. Bolts are threadedly connected in the limiting holes. A plurality of fixing mechanisms are installed between the first ultra-high performance concrete slab and the second ultra-high performance concrete slab. The second gasket is fixedly connected to the baffle. Both ends of the connecting column are movably connected in the connecting grooves, effectively improving the connection stability effect of the equipment and avoiding damage to the equipment during connection;

[0004] The above-mentioned existing technical solutions have the following defects: Since the support base and the baffle are installed on the outer side of the connecting column, when the connecting column is inserted into the connecting groove through the support base, affected by the thickness of the support base, the inner side wall of the connecting groove cannot be attached to the outer side wall of the connecting column, resulting in the connecting column being unstable after being inserted. Although there is secondary reinforcement with bolts, this will reduce the docking and installation efficiency of the two groups of high-performance concrete slabs. In view of the above situation, technical innovation is carried out on the basis of the existing UHPC high-performance concrete components. Content of the Utility Model

[0005] The purpose of the utility model is to provide a UHPC high-performance concrete component to solve the problems put forward in the above background technique.

[0023] Please refer to Figures 1 - 4 , a UHPC high-performance concrete member, including a first high-performance concrete plate 1 and a second high-performance concrete plate 11. Docking grooves 13 are evenly opened on the left and right sides of the outer side walls of the first high-performance concrete plate 1 and the second high-performance concrete plate 11. Card slots 131 are opened on the front and rear sides of the inner side walls of the docking grooves 13. A fixing component is inserted into the docking grooves 13. Pouring holes 12 are evenly opened on the tops of the first high-performance concrete plate 1 and the second high-performance concrete plate 11. The pouring holes 12 correspond to the card slots 131. The fixing component includes a docking column 2. Two groups of mounting holes are evenly opened on the front and rear sides of the outer side wall of the docking column 2. Springs 21 are fixedly arranged in the mounting holes. Round head pins 22 are fixedly arranged on the outer side walls of the springs 21. When the docking column 2 is inserted into the docking groove 13 and the round head pins 22 are aligned with the card slots 131, the springs 21 drive the round head pins 22 to insert into the card slots 131 through their own elastic forces. The docking column 2 is inserted into two groups of opposite docking grooves 13 of the first high-performance concrete plate 1 and the second high-performance concrete plate 11. The round head pins 22 are inserted into the card slots 131. The round head parts of the round head pins 22 are inserted into the card slots 131, and the column parts of the round head pins 22 are located in the mounting holes of the docking column 2 and the card slots 131;

[0024] Two groups of first communication grooves 132 are evenly arranged at the bottom of the pouring hole 12. The first communication grooves 132 communicate with the clamping grooves 131. A second communication groove 133 is communicated and arranged between every two groups of clamping grooves 131. The outer side wall of the docking groove 13 fits with the outer side wall of the docking column 2. The opposite sides of the first high-performance concrete slab 1 and the second high-performance concrete slab 11 are mutually attached.

[0025] Working principle: Press the round head pin 22 inward to make it move into the installation hole of the docking column 2, and then insert the docking column 2 into the opposite docking grooves 13 of the first high-performance concrete slab 1 and the second high-performance concrete slab 11. When the round head pin 22 is aligned with the clamping groove 131, the spring 21 drives the round head pin 22 to insert into the clamping groove 131 through its own elastic force, so as to complete the installation and fixation of the docking column 2. By quickly completing the installation of the docking column 2, the strength of the first high-performance concrete slab 1 and the second high-performance concrete slab 11 after splicing can be effectively improved. Pour the reinforcing agent into the pouring hole 12, and the reinforcing agent flows into each clamping groove 131 along the first communication groove 132 and the second communication groove 133, so as to fix the round head pin 22, and further improve the installation stability of the docking column 2, thereby further improving the strength of the first high-performance concrete slab 1 and the second high-performance concrete slab 11 after splicing.
