Description

Technical Field

[0001] This application relates to the field of concrete component technology, and more particularly to a prefabricated building concrete component. Background Technology

[0002] The published patent, CN219528128U, discloses a prefabricated concrete component for prefabricated buildings, including a prefabricated inner wall panel, a prefabricated outer wall panel, a second inner wall panel, and a second outer wall panel. The prefabricated inner and outer wall panels are perpendicular to each other, and their adjacent end faces are fixedly connected at a 45-degree angle. Similarly, the prefabricated outer wall panels are also perpendicular to each other and their adjacent end faces are fixedly connected at a 45-degree angle. Assembly reinforcing bars are provided between the prefabricated inner and outer wall panels, bent at a right angle from the middle. A grouting connector is provided at the bend of the assembly reinforcing bars. This utility model, by setting assembly reinforcing bars, a first assembly groove, and grouting connectors, assembles the prefabricated inner wall panel, prefabricated outer wall panel, second inner wall panel, and second outer wall panel into a single unit, and then fixes and connects them using grouting connectors. The assembly reinforcing bars, which connect and fix all concrete components, achieve a high-strength assembly function.

[0003] When the above device is implemented, the serrated strips on the surfaces of the inner and outer wall panels are engaged to improve the stability of the building and connect the inner and outer wall panels. However, when connecting, the engagement of the serrated strips on the surfaces of the inner and outer wall panels alone cannot prevent the wall panels from sliding relative to each other in the vertical direction, resulting in misalignment between the inner and outer wall panels. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a prefabricated building concrete component, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a prefabricated concrete component for prefabricated buildings, comprising a prefabricated wall panel one, a prefabricated wall panel two slidably connected to one side of the prefabricated wall panel one, and a plurality of serrated strips fixedly connected to the surfaces of both the prefabricated wall panel two and the prefabricated wall panel one, the plurality of serrated strips being evenly distributed on the surfaces of the prefabricated wall panel two and the prefabricated wall panel one, a positioning mechanism being provided between the prefabricated wall panel two and the prefabricated wall panel one, the positioning mechanism including limiting blocks, a plurality of limiting blocks being provided, the plurality of limiting blocks being evenly installed on both sides of the serrated strips, grooves being formed on the surface of the serrated strips, the grooves being adapted to the limiting blocks, a high-strength elastic sealant being provided between the prefabricated wall panel two and the prefabricated wall panel one, a connecting mechanism being provided inside the high-strength elastic sealant, and a supporting mechanism being provided on the surface of the prefabricated wall panel two.

[0006] In a preferred embodiment, a slot is provided between two adjacent saw teeth, and the slot is adapted to the saw teeth.

[0007] By adopting the above technical solution, the serrated strips on one surface of the precast wall panel are inserted into the slots on the other surface of the precast wall panel to form an interlocking structure, which enhances the tightness of the connection and improves the overall shear resistance of the component.

[0008] In a preferred embodiment, the high-strength elastic sealant is a polyurethane adhesive component, and the high-strength elastic sealant is applied between the precast wall panel two and the precast wall panel one.

[0009] By adopting the above technical solution, using high-strength elastic sealant as a polyurethane adhesive component, and then applying high-strength elastic sealant between precast wall panel two and precast wall panel one, the connection between the wall panels can be better enhanced, and the waterproof, dustproof and sound insulation effects of the components can be improved.

[0010] In a preferred embodiment, the connecting mechanism includes reinforcing bars, which are disposed between precast wall panel two and precast wall panel one. The reinforcing bars are slidably connected to precast wall panel two and precast wall panel one. Reinforcing ribs are fixedly connected to the surface of the reinforcing bars. Annular reinforcing bars are laid inside both precast wall panel two and precast wall panel one, and a wire mesh layer is laid on top of the annular reinforcing bars.

[0011] By adopting the above technical solution, the precast wall panel 2 and precast wall panel 1 can be firmly combined by connecting them with steel bars. The reinforcing bars on the surface can increase the bond strength between the steel bars and the concrete and improve the connection strength. The ring steel bars further enhance the structural strength of the precast wall panel 2 and precast wall panel 1 and resist external impact. The steel wire mesh layer disperses stress and reduces the risk of wall panel cracking. This allows for a better connection between the precast wall panel 2 and precast wall panel 1.

[0012] In a preferred embodiment, the support mechanism includes a support plate that is slidably connected to a precast wall panel. A slider is fixedly connected to the surface of the support plate, and a fixing block is slidably connected to the surface of the slider. The fixing block is fixedly connected to the precast wall panel. Two positioning rods are slidably connected inside the slider. The two positioning rods are symmetrically distributed inside the slider, and a spring is provided between the two positioning rods.

[0013] By adopting the above technical solution, the slider is inserted into the inside of the fixed block, and the position of the slider can be quickly fixed by the cooperation of the positioning rod and the spring, thereby positioning the support plate. This facilitates the installation of bolts to fix the support plate to the surface of the precast wall panel two, and the support plate supports the precast wall panel two, preventing the precast wall panel two from tilting or deforming due to uneven force, thus providing better support for the precast wall panel two.

[0014] In a preferred embodiment, a limiting hole is formed on the surface of the fixing block, and the limiting hole is adapted to the positioning rod.

[0015] By adopting the above technical solution, a limiting hole is opened on the surface of the fixing block, and the limiting hole is adapted to the positioning rod, so that the positioning rod can be better inserted into the interior of the fixing block.

[0016] In a preferred embodiment, the slider has an internal receiving groove that is adapted to the positioning rod.

[0017] By adopting the above technical solution, a receiving groove is provided inside the slider to provide storage space for the positioning rod, allowing the positioning rod to slide inside the slider, which can better enable the positioning rod to slide inside the slider.

[0018] The beneficial effects of this application are: 1. This prefabricated concrete building component utilizes high-strength elastic sealant, grooves, and limiting blocks. By inserting serrated strips from the surface of one prefabricated wall panel into slots on the surface of another prefabricated wall panel, an interlocking structure is formed, enhancing the tightness of the connection and improving the overall shear resistance of the component. The limiting blocks are then inserted into the grooves to position the wall panels, preventing them from sliding vertically. High-strength elastic sealant is applied between the second and first prefabricated wall panels to further strengthen the connection, improving the component's waterproof, dustproof, and sound insulation properties. This design avoids the problem of misalignment during installation caused by the serrated strips on the surfaces of the inner and outer wall panels alone during connection, which fails to prevent vertical sliding. This design improves practicality.

[0019] 2. This prefabricated building concrete component, by setting up a support plate, fixing block, positioning rod, spring and slider, allows the slider to be inserted into the fixing block, and the positioning rod and spring work together to quickly fix the position of the slider, thereby positioning the support plate. This facilitates the installation of bolts to fix the support plate to the surface of the prefabricated wall panel two, and the support plate supports the prefabricated wall panel two, preventing the prefabricated wall panel two from tilting or deforming due to uneven force. This avoids the problem of existing prefabricated building concrete components being unable to support the prefabricated wall panel two, thus improving practicality. Attached Figure Description

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] Reference Figures 1-4 A prefabricated concrete component for prefabricated buildings includes a prefabricated wall panel 1, a prefabricated wall panel 2 5 slidably connected to one side of the prefabricated wall panel 1, and a plurality of serrated strips 6 fixedly connected to the surfaces of both the prefabricated wall panel 2 5 and the prefabricated wall panel 1. The plurality of serrated strips 6 are evenly distributed on the surfaces of the prefabricated wall panel 2 5 and the prefabricated wall panel 1. A positioning mechanism 2 is provided between the prefabricated wall panel 2 5 and the prefabricated wall panel 1. The positioning mechanism 2 includes a limiting block 23, and a plurality of limiting blocks 23 are provided. The plurality of limiting blocks 23 are evenly installed on both sides of the serrated strips 6. The surface of the serrated strips 6 is provided with grooves 22, which are adapted to the limiting blocks 23. A high-strength elastic sealant 21 is provided between the prefabricated wall panel 2 5 and the prefabricated wall panel 1. A connecting mechanism 3 is provided inside the high-strength elastic sealant 21. A supporting mechanism 4 is provided on the surface of the prefabricated wall panel 2 5.

[0024] Reference Figures 1-3 A slot 7 is provided between two adjacent sawtooth strips 6, and the slot 7 is adapted to the sawtooth strip 6; by inserting the sawtooth strip 6 on the surface of the precast wall panel 1 into the slot 7 on the surface of the precast wall panel 2 5, an interlocking structure is formed, which enhances the tightness of the connection and improves the overall shear resistance of the component.

[0025] Reference Figures 1-3 The high-strength elastic sealant 21 is a polyurethane adhesive component. The high-strength elastic sealant 21 is applied between the precast wall panel 25 and the precast wall panel 1. By using the high-strength elastic sealant 21 as a polyurethane adhesive component and applying it between the precast wall panel 25 and the precast wall panel 1, the connection between the wall panels can be better enhanced, and the waterproof, dustproof and sound insulation effects of the components can be improved.

[0026] Reference Figure 3The connecting mechanism 3 includes a reinforcing bar 31, which is positioned between precast wall panel 2 5 and precast wall panel 1. The reinforcing bar 31 is slidably connected to precast wall panel 2 5 and precast wall panel 1. Reinforcing ribs 32 are fixedly connected to the surface of the reinforcing bar 31. Annular reinforcing bars 33 are laid inside both precast wall panel 2 5 and precast wall panel 1. A wire mesh layer 34 is laid on top of the annular reinforcing bars 33. By connecting precast wall panel 2 5 and precast wall panel 1 with the reinforcing bar 31, the two can be firmly bonded together. The reinforcing ribs 32 on the surface can increase the bond strength between the reinforcing bar 31 and the concrete, thereby improving the connection strength. The annular reinforcing bars 33 further enhance the structural strength of precast wall panel 2 5 and precast wall panel 1, resisting external impact. The wire mesh layer 34 disperses stress, reducing the risk of wall panel cracking. This allows for a better connection between precast wall panel 2 5 and precast wall panel 1.

[0027] Reference Figure 4 The support mechanism 4 includes a support plate 41, which is slidably connected to the precast wall panel 5. A slider 45 is fixedly connected to the surface of the support plate 41, and a fixing block 42 is slidably connected to the surface of the slider 45. The fixing block 42 is fixedly connected to the precast wall panel 5. Two positioning rods 43 are slidably connected inside the slider 45. The two positioning rods 43 are symmetrically distributed inside the slider 45, and a spring 44 is provided between the two positioning rods 43. By inserting the slider 45 into the fixing block 42, the position of the slider 45 can be quickly fixed by the cooperation of the positioning rods 43 and the spring 44, thus positioning the support plate 41. This facilitates the installation of bolts to fix the support plate 41 to the surface of the precast wall panel 5, and the support plate 41 supports the precast wall panel 5, preventing it from tilting or deforming due to uneven force, thus providing better support for the precast wall panel 5.

[0028] Reference Figures 3-4 The surface of the fixing block 42 is provided with a limiting hole, which is adapted to the positioning rod 43. By providing a limiting hole on the surface of the fixing block 42 and adapting it to the positioning rod 43, the positioning rod 43 can be better inserted into the interior of the fixing block 42.

[0029] Reference Figure 4 The slider 45 has a receiving groove inside, which is adapted to the positioning rod 43. The receiving groove inside the slider 45 provides storage space for the positioning rod 43, allowing the positioning rod 43 to slide inside the slider 45, which can better enable the positioning rod 43 to slide inside the slider 45.

[0030] Working principle: Reinforcing bars 31 are placed between precast wall panel 1 and precast wall panel 2. The serrated edges 6 on the surface of precast wall panel 1 are inserted into the slots 7 on the surface of precast wall panel 2.5, forming an interlocking structure that enhances the tightness of the connection and improves the overall shear resistance of the component. Reinforcing bars 31 then connect precast wall panel 2.5 and precast wall panel 1, firmly bonding them together. The reinforcing ribs 32 on the surface increase the bond strength between the reinforcing bars 31 and the concrete, further enhancing the connection strength. The ring-shaped reinforcing bars 33 further strengthen the structural strength of precast wall panel 2.5 and precast wall panel 1, resisting external impacts. Finally, the serrated edges 6 on the surface of precast wall panel 1 are inserted into the slots 7 on the surface of precast wall panel 2.5, causing the limiting block 23 to insert into the groove 22, thus fixing the wall panel. The positioning mechanism prevents the wall panels from sliding vertically relative to each other, forming an interlocking structure that enhances the tightness of the connection and improves the overall shear resistance of the component. High-strength elastic sealant 21 is then applied between precast wall panel 2 5 and precast wall panel 1 to further strengthen the connection between the wall panels and improve the waterproof, dustproof, and sound insulation properties of the component. A wire mesh layer 34 disperses stress, reducing the risk of wall panel cracking. A slider 45 is then inserted into the fixing block 42, and the positioning rod 43 and spring 44 work together to quickly fix the position of the slider 45, positioning the support plate 41. This facilitates the installation of bolts to fix the support plate 41 to the surface of precast wall panel 2 5. The support plate 41 then supports precast wall panel 2 5, preventing it from tilting or deforming due to uneven stress.
