Description

Technical Field

[0001] This utility model relates to the field of precast components, and more specifically, to a composite precast concrete component. Background Technology

[0002] Precast concrete components are building components made of concrete and produced in factories using standardized processes. They include structural load-bearing components such as beams, slabs, columns, and shear walls, as well as municipal landscape components such as stairs and pipe corridors. When installing precast components, two or more identical components need to be assembled together to form a wall. However, the current use of precast concrete components still has the following drawbacks: Currently, when installing precast concrete components, they are generally placed directly from top to bottom, and the holes at the bottom of the component are aligned with the pre-embedded reinforcing bars. This method cannot ensure the sealing between two adjacent components, thus affecting the normal use of the wall surface. To address this, a composite precast concrete component is proposed. Utility Model Content

This method cannot ensure the sealing between two adjacent components, thus affecting the normal use of the wall surface.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a modular precast concrete component, including a precast component body, wherein a connecting mechanism for assembling multiple precast component bodies is provided on the outside of the precast component body, and a disassembly component for facilitating disassembly of the connecting mechanism is provided on the outside of the connecting mechanism. The connecting mechanism includes a guide rail and a convex column fixedly connected to opposite side walls of the precast body. Each convex column has a convex groove on its opposite side wall. A slider is slidably connected inside the convex groove. A limit plate is fixedly connected to the side wall of the slider. A spring is fixedly connected to the side wall of the limit plate. Limit holes are opened on opposite side walls of the guide rail. The slider is slidably connected to the limit holes.

[0005] As a preferred technical solution of this utility model, the disassembly assembly includes a strip groove formed on the opposite side wall of the bottom end of the convex column, and strip holes are formed on the opposite side wall of the bottom end of the guide rail, and the strip holes are connected to the strip groove.

[0006] As a preferred technical solution of this utility model, an inclined surface is provided on the bottom side wall of the slider, and a blocking block that cooperates with the inclined surface is fixedly connected to the bottom of the limiting hole. The blocking block is in the shape of a right triangle, and the hypotenuse of the blocking block is in close contact with the inclined surface.

[0007] As a preferred technical solution of this utility model, the bottom of the precast component body is provided with a plurality of circular grooves that connect the precast component body to the external steel bars, and the plurality of circular grooves are evenly distributed along the length direction of the precast component body.

[0008] As a preferred technical solution of this utility model, a rectangular groove is provided on the side wall of the slider away from the convex column to facilitate the movement of the slider.

[0009] As a preferred technical solution of this utility model, baffles are bolted to the opposite side walls of the guide rail to prevent debris from entering the convex groove.

[0010] As a preferred technical solution of this utility model, a guide rod is fixedly connected inside the convex groove, one end of the guide rod passes through the limiting plate and is slidably connected to the limiting plate, and the spring is located outside the guide rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Using the set connection mechanism, insert the convex post from top to bottom along the guide rail. Press the two sliders to bring them closer together until one end of the slider enters the convex groove. Then continue to move the convex post down.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0015] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0016] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0017] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0018] like Figure 1 As shown, this embodiment proposes a modular precast concrete component, including a precast component body 1, a connecting mechanism 2 for combining multiple precast component bodies 1 is provided on the outside of the precast component body 1, and a disassembly assembly 3 for easy disassembly of the connecting mechanism 2 is provided on the outside of the connecting mechanism 2. like Figure 3 , Figure 4 and Figure 6As shown, the connecting mechanism 2 includes a guide rail 201 and a convex column 202 fixedly connected to the opposite side walls of the precast body 1. The convex column 202 is slidably connected to the guide rail 201. A convex groove 203 is provided on the opposite side walls of the convex column 202. A slider 204 is slidably connected inside the convex groove 203. A limit plate 205 is fixedly connected to the side wall of the slider 204. A spring 206 is fixedly connected to the side wall of the limit plate 205. Limit holes 207 are provided on the opposite side walls of the guide rail 201. The slider 204 is slidably connected to the limit holes 207. When it is necessary to combine two adjacent precast bodies 1, i.e. A prefabricated body 1 and a convex post 202 can be inserted into the guide rail 201 from top to bottom. When one end of the slider 204 contacts the top of the guide rail 201, the two sliders 204 can be pressed to bring them closer together. At this time, the spring 206 contracts. When one end of the slider 204 enters the convex groove 203, the convex post 202 loses its restriction and continues to descend along the guide rail 201. When the bottom end of the convex post 202 is at the same level as the bottom end of the guide rail 201, the elastic force of the spring 206 will push the slider 204 into the limiting hole 207, so that the two prefabricated bodies 1 can be quickly combined.

[0019] like Figure 4 As shown, the disassembly assembly 3 includes a strip groove 301 on the opposite side wall of the bottom end of the convex column 202. A strip hole 302 is provided on the opposite side wall of the bottom end of the guide rail 201. The strip hole 302 communicates with the strip groove 301. After assembling the two prefabricated body 1, if it is necessary to disassemble the prefabricated body 1 again, one end of the external pry bar can be inserted into the strip hole 302 and the strip groove 301 in sequence. Then, press the two sliders 204 again so that one end of the slider 204 enters the convex groove 203. Then, press down the end of the pry bar away from the prefabricated body 1. Then, the prefabricated body 1 can be taken out with the help of external lifting equipment.

[0020] like Figure 6 As shown, a slope is provided on the bottom side wall of the slider 204. A blocking block 4 that works with the slope is fixedly connected to the bottom of the limiting hole 207. The blocking block 4 is a right triangle in shape. The hypotenuse of the blocking block 4 fits tightly with the slope. When in use, the blocking block 4 can prevent external debris from entering the convex groove 203. By providing a slope on the slider 204, the slope can contact the guide rail 201 when the slider 204 contacts the top of the guide rail 201. At this time, the slider 204 can be moved without manually pressing it.

[0021] like Figure 5As shown, the bottom of the precast body 1 has several circular grooves 5 that connect the precast body 1 to the external reinforcing bars. The circular grooves 5 are evenly distributed along the length of the precast body 1. The inside of the circular grooves 5 is provided with sleeves. When in use, the precast body 1 is placed above the embedded reinforcing bars from top to bottom, and then the sleeves are placed on the external reinforcing bars, so that the bottom of the precast body 1 can be quickly positioned.

[0022] like Figure 6 As shown, a rectangular groove 6 is provided on the side wall of the slider 204 away from the convex post 202 to facilitate the movement of the slider 204. When disassembling the prefabricated body 1, an external screwdriver can be used. One end of the screwdriver is placed inside the rectangular groove 6, and then the screwdriver is pushed. This avoids the hand from bumping against the guide rail 201 when manually pressing the slider 204, thus ensuring safety.

[0023] like Figure 1 As shown, baffles 7 are bolted to the opposite side walls of the guide rail 201 to prevent debris from entering the convex groove 203. After the two prefabricated body 1 is assembled, the two prefabricated body 1 are bolted to the side wall of the guide rail 201, which can ensure the cleanliness of the inside of the convex groove 203 during subsequent construction.

[0024] like Figure 6 As shown, a guide rod 8 is fixedly connected inside the convex groove 203. One end of the guide rod 8 passes through the limiting plate 205 and is slidably connected to the limiting plate 205. The spring 206 is located outside the guide rod 8. When in use, the guide rod 8 can guide the limiting plate 205 and also prevent the spring 206 from bending in all directions.

[0025] Specifically, when using this precast concrete component: Insert one precast component body 1 and the convex column 202 into the guide rail 201 from top to bottom. When one end of the slider 204 contacts the top of the guide rail 201, the inclined surface will contact the guide rail 201. Continue to move the convex column 202 downwards; without manually pressing the slider 204, the two sliders 204 can move closer together. At this time, the spring 206 contracts. When one end of the slider 204 enters the convex groove 203, the convex column 202 loses its restraint and continues to descend along the guide rail 201. When the bottom end of the convex column 202 is at the same horizontal plane as the bottom end of the guide rail 201, the elastic force of the spring 206 will push the slider 204 into the limiting hole 207, thus quickly assembling the two precast component bodies 1 (e.g., ...). Figure 4 and Figure 6(As shown), if it is necessary to disassemble the precast body 1 again, insert one end of the external pry bar into the slot 302 and the groove 301 in sequence, then press the two sliders 204 again so that one end of the slider 204 enters the convex groove 203. Then press down the end of the pry bar away from the precast body 1 so that the slider 204 fits against the inner wall of the guide rail 201. Then, the precast body 1 can be removed again with the help of external lifting equipment (as shown). Figure 4 and Figure 6 (As shown).

[0026] All technical features in this embodiment can be freely combined according to actual needs.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
