Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, and in particular to a splicing prefabricated component. Background Technology
[0002] Precast concrete blocks are concrete blocks manufactured in advance in factories or on construction sites. These blocks are commonly used in building and foundation structures. Precast concrete blocks have uniform quality and size, which can improve construction efficiency and reduce on-site waste. Interlocking precast components are structures used to produce precast concrete blocks.
[0003] Currently used precast splicing components are mainly composed of multiple single components assembled together. During splicing, adjacent components are directly attached to each other. This direct contact splicing can easily lead to unstable connection between adjacent components. At the same time, the splicing position is not tight enough, affecting the airtightness of the splicing position between adjacent components. This can easily lead to leakage of concrete during the precasting process, affecting the performance of the precast components. Therefore, a splicing precast component is proposed.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides, for example Figures 1-4 The image shows a type of prefabricated modular component.
[0023] Example 1 includes a left end frame 100, a right end frame 106, and a locking member 200. Both ends of the left end frame 100 have V-shaped recesses 103. Both ends of the right end frame 106 opposite the left end frame 100 have conical protrusions 102 that match the V-shaped recesses 103. The locking member 200 is located on the front and rear sides between the left end frame 100 and the right end frame 106, and is used to lock the left end frame 100 and the right end frame 106 together. When the left end frame 100 and the right end frame 106 are joined, because the conical protrusions 102 and V-shaped recesses 103 are respectively provided at opposite ends of the left end frame 100 and the right end frame 106, the mating ends of the left end frame 100 and the right end frame 106 are engaged through the interlocking of the conical protrusions 102 and the V-shaped recesses 103. Positioning enhances the stability of the connection between the left end frame 100 and the right end frame 106. The interlocking between the conical protrusion 102 and the V-shaped recess 103 increases the contact area at the joint, making the contact surfaces tighter and improving the sealing of the connection. This effectively prevents concrete leakage at the joint, improving performance. Furthermore, the locking fastener 200 provides opposing compressive forces to the left end frame 100 and the right end frame 106, ensuring that the conical protrusion 102 and the V-shaped recess 103 maintain opposing compressive forces, further strengthening the joint's rigidity.
[0024] Furthermore, a first splicing plate 101 is provided between the left end frame 100 and the right end frame 106. A conical protrusion 102 is provided at the end of the first splicing plate 101 near the left end frame 100, and a V-shaped recess 103 is provided at the end of the first splicing plate 101 near the right end frame 106. By adding a first splicing plate 101 with a conical protrusion 102 and a V-shaped recess 103 at both ends between the left end frame 100 and the right end frame 106, the corresponding number and length of the first splicing plates 101 can be selected and added to the position between the left end frame 100 and the right end frame 106 according to the length requirements of the precast concrete blocks. This not only ensures the tightness of the splicing position of the left end frame 100, the first splicing plate 101 and the right end frame 106, but also adapts to the processing requirements of precast concrete blocks of various sizes, improving the adaptability of precast components.
[0025] The locking fastener 200 includes a male locking end and a female locking end. The male locking end is fixedly disposed on the outer wall of the left end frame 100 and the end of the first splicing plate 101 away from the outer wall of the left end frame 100. The female locking end is fixedly disposed on the outer wall of the right end frame 106 and the end of the first splicing plate 101 away from the outer wall of the right end frame 106. Preferably, the male locking end includes a U-shaped plate 204, and both ends of the U-shaped plate 204 are fixedly connected to supporting angle steel 205. The female locking end includes a hinge seat 201. A hinge block 202 is rotatably connected to the middle of component 01. One end of the hinge block 202 is fixedly connected to a threaded rod 203, and a nut seat 206 is threadedly connected to the outer wall of the threaded rod 203. The U-shaped plate 204 and the supporting angle steel 205 are fixedly connected to the corresponding side walls 100, 101, or 106. Similarly, 201 is fixed to the corresponding side walls 100, 101, and 106. It is necessary to ensure that 204 and 201 are installed on adjacent components at the same horizontal height. In practical use… Simply rotate the threaded rod 203 manually, and the hinge block 202 rotates around the hinge seat 201, allowing the threaded rod 203 to rotatably insert into the groove in the middle of the adjacent U-shaped plate 204. This positions the nut seat 206 on the side of the U-shaped plate 204 away from the hinge seat 201. Then, by tightening the nut seat 206, it presses against the outer wall of the U-shaped plate 204. This pressing force maintains the fixed position of the threaded rod 203 and the U-shaped plate 204. Furthermore, by utilizing the squeezing action of the nut seat 206, a pulling force is generated between the U-shaped plate 204 and the hinge seat 201. This ensures that the splicing positions of adjacent parts of the left end frame 100, the first splicing plate 101, and the right end frame 106 are pressed and fixed. To unlock, simply rotate the nut seat 206 away from the U-shaped plate 204 in the opposite direction to release the lock on the threaded rod 203, allowing the threaded rod 203 to rotate and separate from the U-shaped plate 204. The operation is simple and convenient, and the locking effect is good.
[0026] Example 2, based on Example 1, further illustrates that the left end frame 100 and the right end frame 106 are composed of two right-angled blocks 104. Each of the two right-angled blocks 104 has a V-shaped recess 103 at one end facing the same direction, and a conical protrusion 102 and a V-shaped recess 103 at the opposite ends. A second splicing plate 105 is provided between the two right-angled blocks 104. Both ends of the second splicing plate 105 have conical protrusions 102 and V-shaped recesses 103, respectively. Locking fasteners 200 are installed on the outer wall between the splicing plates 105. By setting the independent left end frame 100 and right end frame 106 as a split structure, a corresponding number and length of second splicing plates 105 can be added between the two right-angle blocks 104 according to the width requirements of the precast concrete blocks. Then, the locking fasteners 200 are used to lock the position between the second splicing plates 105 and the right-angle blocks 104, thereby achieving the purpose of adjusting the width of the left end frame 100 and the right end frame 106, thus better adapting to the precasting requirements of various precast concrete blocks.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
