Description

Technical Field

[0001] This utility model relates to the field of UHPC concrete component technology, and in particular to a spliced ​​UHPC concrete component. Background Technology

[0002] Ultra-high performance concrete (UHPC) components possess numerous superior properties. They exhibit extremely high strength, with compressive strength exceeding 150 MPa, far surpassing ordinary concrete. They demonstrate excellent durability, effectively resisting chemical erosion and abrasion, significantly extending their service life. UHPC concrete components have very low porosity, resulting in a denser structure. Aesthetically, they allow for refined shapes and surface textures, meeting architectural aesthetic requirements. In practical applications, they can be used to manufacture bridge components, reducing structural weight while enhancing load-bearing capacity; they can also be used in building facades, showcasing unique architectural styles, making them a highly promising material for modern architecture and infrastructure construction.

[0003] Due to the significant challenges of on-site construction of UHPC concrete, it is often difficult to precisely control errors and quality. While prefabricated UHPC concrete components can be assembled on-site, significantly shortening the construction cycle and improving efficiency, their weight necessitates repeated adjustments by workers during on-site assembly. This makes rapid and precise alignment difficult over extended periods, impacting overall assembly efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a spliced ​​UHPC concrete component.

[0005] This utility model is achieved by the following technical solution: a splicing UHPC concrete component, including a splicing mechanism, a fixing mechanism and a main body mechanism, wherein the splicing mechanism is located on the side wall of the main body mechanism and the fixing mechanism is located on the outer surface of the main body mechanism;

[0006] The splicing mechanism includes a locking base, a spring is locked inside the locking base, and a locking block is fixedly connected to the top of the spring.

[0007] Through the above technical solution, the locking block base is connected to the spring, and the spring is fixedly connected to the locking block. When assembling the concrete components, the locking block retracts downward and squeezes the spring to store force. When the locking block base enters the slot, the spring releases its elastic potential energy, which can cause the locking block to reset and contact the slot. The spring continuously provides support force to the locking block, which can make the locking block and the slot fit tightly together, thereby realizing the pre-installation of two concrete components. Conversely, when dismantling the concrete components, only a pulling force greater than the spring support force needs to be applied to separate the two concrete components and splice them together by the locking block, thereby increasing the convenience of use.

[0008] As a further improvement to the above solution, a slider is fixedly connected to the bottom of the card block, a groove is slidably connected to the outer wall of the slider, and a mounting plate is fixedly connected to the bottom of the card block base.

[0009] Through the above technical solution, the card block is fixedly connected to the slider, so that when the card block moves up and down, it can drive the slider to slide on the inner wall of the groove. Thus, the groove can provide guidance for the movement of the slider and the card block, and at the same time limit the movement range of the card block, prevent the card block from falling off when moving upward, and increase the stability of the card block when moving.

[0010] As a further improvement to the above solution, the top of the card block is fitted with a card slot, and the front end of the card slot is provided with a guide groove.

[0011] Through the above technical solution, the card block engages with the card slot, and a guide groove is provided at the top of the card slot. By setting the guide groove to be arc-shaped, when the card block comes into contact with the guide groove, the guide groove will squeeze the card block, allowing it to retract into the card block base. This allows the card block base to smoothly enter the card slot, increasing the convenience of the splicing process.

[0012] As a further improvement to the above solution, the fixing mechanism includes a fixing steel plate, and the outer wall of the fixing steel plate is fixedly connected with locking bolts.

[0013] Through the above technical solution, the fixing steel plate is fixedly connected to the locking bolt. The fixing steel plate on both sides of the main body of the component can be fixed by the locking bolt. In this way, the splicing gap between the two main body components can be reinforced by fixing the steel plate, thereby increasing the overall structural strength of the spliced ​​concrete component.

[0014] As a further improvement to the above solution, a limiting plate is fixedly connected to the back of the fixed steel plate.

[0015] Through the above technical solution, the fixed steel plate is fixedly connected to the limiting plate. By setting multiple limiting plates on the back of the fixed steel plate and having the limiting plates in contact with the mounting plate, the position of the mounting plate and the main body of the component can be fixed by the limiting plates to prevent them from bending, thereby further increasing the overall structural rigidity of the spliced ​​concrete component.

[0016] As a further improvement to the above solution, the main structure includes a component body, the outer wall of which is provided with a water guide groove, and a steel mesh is fixedly connected inside the component body.

[0017] Through the above technical solution, a water guide groove is provided on the outer wall of the main body of the component. By setting the water guide groove, the drainage effect of the main body of the component can be increased, and water can be prevented from accumulating on the surface of the main body of the component and seeping in, thereby extending the service life of the component. A steel mesh is set to fix the main body of the component. By setting the steel mesh on the inner wall of the main body of the component, the structural strength of the main body of the component can be improved and the overall load-bearing capacity can be enhanced.

[0018] As a further improvement to the above solution, the side of the main body of the component is fixedly connected with an embedded part.

[0019] Through the above technical solution, the main body of the component is fixedly connected to the embedded part. By fixing the embedded part to the side of the main body of the component, it can be connected to the mounting plate through the embedded part, thereby increasing the overall structural strength after splicing.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention features a locking block base that engages with a spring, with the spring providing a fixed connection to the locking block. During the assembly of concrete components, the locking block retracts downwards, compressing the spring to store energy. Once the locking block base enters the slot, the spring releases its potential energy, causing the locking block to reset and contact the slot. The spring continuously provides support, ensuring a tight fit between the locking block and the slot for pre-installation. Conversely, during disassembly, only a pulling force greater than the spring's support force is needed to separate the components. The locking block facilitates assembly, increasing ease of use. A locking block is also fixedly connected to a slider, allowing the slider to slide along the inner wall of the groove as the locking block moves up and down. This groove guides the movement of the slider and locking block, limiting the block's range of motion and preventing it from detaching during upward movement, thus increasing stability. The locking block engages with a slot, the top of which has a guide groove. By designing the guide groove as an arc, the locking block is compressed when it contacts it, allowing it to smoothly enter the slot with the locking block base, further enhancing the ease of assembly.

[0022] This utility model uses a fixed steel plate to fix and connect locking bolts. The locking bolts can lock the fixed steel plates on both sides of the main body of the component, thereby reinforcing the splicing gap between the two main body components and increasing the overall structural strength of the spliced ​​concrete component. The fixed steel plate is also equipped with a fixed and connected limiting plate. By setting multiple limiting plates on the back of the fixed steel plate and having them in contact with the mounting plate, the limiting plates can fix the position of the mounting plate and the main body of the component to prevent bending, thereby further improving the overall structural rigidity.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-5 This embodiment of a splicing UHPC concrete component includes a splicing mechanism 1, a fixing mechanism 2, and a main body mechanism 3. The splicing mechanism 1 is located on the side wall of the main body mechanism 3, and the fixing mechanism 2 is located on the outer surface of the main body mechanism 3.

[0033] The splicing mechanism 1 includes a locking base 101, a spring 102 is locked inside the locking base 101, and a locking block 103 is fixedly connected to the top of the spring 102.

[0034] The bottom of the card block 103 is fixedly connected to a slider 104, the outer wall of the slider 104 is slidably connected to a groove 105, and the bottom of the card block base 101 is fixedly connected to a mounting plate 106.

[0035] The top of the card block 103 is engaged with a card slot 107, and the front end of the card slot 107 is provided with a guide groove 108.

[0036] The fixing mechanism 2 includes a fixing steel plate 201, and a locking bolt 202 is fixedly connected to the outer wall of the fixing steel plate 201.

[0037] A limiting plate 203 is fixedly connected to the back of the fixed steel plate 201.

[0038] The main structure 3 includes a component body 301, a water guide groove 302 is provided on the outer wall of the component body 301, and a steel mesh 303 is fixedly connected inside the component body 301.

[0039] The side of the main component 301 is fixedly connected with an embedded part 304.

[0040] The implementation principle of a splicing UHPC concrete component in this embodiment is as follows: A locking block base 101 engages with a spring 102, and the spring 102 is fixedly connected to a locking block 103. When assembling the concrete component, the locking block 103 retracts downwards and compresses the spring 102 to store force. When the locking block base 101 enters the locking groove 107, the spring 102 releases its potential energy, causing the locking block 103 to reset and contact the locking groove 107. The spring 102 continuously provides support, ensuring a tight fit between the locking block 103 and the locking groove 107, thus achieving... The components are pre-installed; conversely, during disassembly, only a pulling force greater than the supporting force of spring 102 needs to be applied to separate the components. They are then assembled using locking blocks 103, increasing ease of use. Locking blocks 103 are fixedly connected to slider 104, so that when locking blocks 103 move up and down, they can drive slider 104 to slide on the inner wall of slide groove 105. This provides guidance for the movement of slider 104 and locking blocks 103 through slide groove 105, while also limiting the range of movement of locking blocks 103 to prevent them from jamming. 3. To improve the stability of the movement of the locking block 103, the locking block 101 is designed to engage with the locking slot 107. A guide groove 108 is provided at the top of the locking slot 107. By making the guide groove 108 arc-shaped, the locking block 101 is compressed when it contacts the guide groove 108, allowing it to smoothly enter the locking slot 107 with the locking block base 101, thus increasing the ease of assembly. A fixing steel plate 201 is used to fix and connect the locking bolt 202, which allows the main body of the component to be aligned. The two fixed steel plates 201 on the opposite sides are locked together, thereby reinforcing the splicing gap between the two main components and increasing the overall structural strength of the spliced ​​concrete component. By setting multiple limiting plates 203 on the back of the fixed steel plate 201 and having the limiting plates 203 in contact with the mounting plate 106, the positions of the mounting plate 106 and the main component 301 can be fixed by the limiting plates 203 to prevent bending, thereby further improving the overall structural rigidity.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
