[0002] Prefabricated building wall panels use a steel pipe frame as the load-bearing skeleton, with pre-set through grouting channels within the frame. During prefabrication, the steel pipes, panels, ribs, and other components are integrally formed. During installation, high-strength grout is injected into the steel pipes and connecting nodes through the grouting channels, forming a composite stress system between the steel pipes and concrete. This also achieves rigid connections between components. It combines the high efficiency of prefabrication with the high strength of steel pipe concrete, simplifies the construction process, improves the overall structural integrity, and is suitable for the wall structures of prefabricated buildings.

[0003] In the current installation of prefabricated wall panels, when reinforcing bars are installed in the grouting channels, the lack of effective positioning and reinforcement methods can easily lead to relative displacement and unstable connection between the channels and reinforcing bars, resulting in incomplete grouting and affecting the connection strength and integrity of the wall panel and the structure. Therefore, it is necessary to design a prefabricated building wall panel with a positioning and reinforcement structure to ensure a stable connection between the grouting channels and reinforcing bars, avoid relative displacement, ensure grouting density, improve the connection strength between the wall panel and the structure, facilitate installation, and enhance the overall integrity and stability of the wall panel. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated building wall panel with advantages such as positioning and reinforcement structure to ensure stable connection between grouting channel and steel bar, avoid relative displacement, ensure grouting density, improve the connection strength between wall panel and structure, convenient installation, and enhance the integrity and stability of wall panel, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A prefabricated building wall panel includes a transverse connecting bar set on the top of a concrete base. The prefabricated wall panel is fixedly connected to the top of the concrete base. The transverse connecting bar is set through the left and right sides and the top of the prefabricated wall panel. A grouting channel is set through the inner cavity of the prefabricated wall panel. Multiple grooves are opened at the bottom of the prefabricated wall panel. The grooves are located at the bottom of the grouting channel. A grouting sealing block is fixedly connected to the inner cavity of the groove. Multiple reinforcing bars are set through the top of the concrete base. The reinforcing bars penetrate into the inner cavity of the grouting channel. A limit sleeve is set on the surface of the reinforcing bars. Two symmetrical connecting reinforcing bars are fixedly connected to the inner cavity of the grouting sealing block. The opposite side of the two connecting reinforcing bars is fixed to the surface of the limit sleeve. Two symmetrical transverse tie bars are fixedly connected to the top of the inner cavity of the grouting sealing block. The two transverse tie bars are fixedly connected to the top of the surface of the limit sleeve.

[0006] Preferably, a connecting sleeve is fixedly connected to the top of the grouting sealing block, and the connecting sleeve is fitted onto the bottom of the grouting channel surface.

[0007] Preferably, the bottom of the inner cavity of the grouting sealing block is fixedly connected to two symmetrical oblique reinforcing ribs, and the opposite side of the two oblique reinforcing ribs is fixedly connected to the bottom of the surface of the limiting sleeve.

[0008] Preferably, the top and bottom of the two connecting reinforcing ribs are fixedly connected to side support ribs, and the end of the side support rib away from the connecting reinforcing rib is fixedly connected to the diagonal reinforcing rib and the transverse tie rib, respectively.

[0009] Preferably, the top of each of the two transverse tie bars is fixedly connected with an oblique anchor bar, and the end of each of the two oblique anchor bars away from the transverse tie bar is fixedly connected to the surface of the steel bar.

[0010] The beneficial effects of this utility model are: 1.

Through the combined use of limiting sleeves, connecting reinforcing bars and transverse tie bars, the position of the steel bars is stable when the grouting channel and the steel bars are fixed together. Finally, concrete grout is poured into the inner cavity of the grouting channel and flows into the inner cavity of the entire grouting sealing block. At this time, the gap between the steel bars and the limiting sleeve will also be filled by the concrete grout. This achieves the purpose of positioning and reinforcing the structure to ensure the stable connection between the grouting channel and the steel bars, avoid relative displacement, ensure grouting density, improve the connection strength between the wall panel and the structure, facilitate installation, and enhance the integrity and stability of the wall panel. 2. By setting up a connecting sleeve, this utility model can fix the grouting sealing block when it is set at the bottom of the grouting channel, ensuring that the grouting sealing block will not shift due to impact force when the concrete grout is poured into the inner cavity of the grouting sealing block, thus improving the stability of the grouting sealing block. 3. By setting the side support ribs, the side support ribs work together with the connecting stiffeners, diagonal stiffeners and transverse tie bars to provide a stable support base for the three, which can help disperse stress, make the connecting stiffeners transmit the nodal stress more efficiently, enhance the diagonal stress stability of the diagonal stiffeners, and improve the transverse tie stiffness of the transverse tie bars.

Detailed Implementation

[0012] In the following description, embodiments of the prefabricated wall panel of the present invention, in which the steel pipe also serves as a grouting channel, will be described with reference to the accompanying drawings.

[0013] Figure 1-5This invention illustrates an embodiment of a prefabricated wall panel that uses a steel pipe as a grouting channel. It includes a transverse connecting rib 3 positioned at the top of a concrete base 1. A prefabricated wall panel 2 is fixedly connected to the top of the concrete base 1. The transverse connecting rib 3 extends through the left and right sides and the top of the prefabricated wall panel 2. A grouting channel 4 extends through the inner cavity of the prefabricated wall panel 2. Multiple grooves 5 are formed at the bottom of the prefabricated wall panel 2, located at the bottom of the grouting channel 4. Grouting sealing blocks 6 are fixedly connected to the inner cavity of the grooves 5, and connecting sleeves 7 are fixedly connected to the top of the grouting sealing blocks 6. The connecting sleeve 7 is fitted onto the bottom of the grouting channel 4. Through the connecting sleeve 7, when the grouting sealing block 6 is placed at the bottom of the grouting channel 4, the connecting sleeve 7 fixes the grouting sealing block 6, ensuring that the grouting sealing block 6 will not shift due to impact force when concrete grout is poured into its inner cavity, thus improving the stability of the grouting sealing block 6. Multiple reinforcing bars 8 are installed through the top of the concrete base 1, extending into the inner cavity of the grouting channel 4. Limit sleeves 9 are provided on the surface of the reinforcing bars 8. Two symmetrical connecting reinforcing bars are fixedly connected to the inner cavity of the grouting sealing block 6. 10. Two connecting reinforcing ribs 10 are fixed to the surface of the limiting sleeve 9 on opposite sides. Two symmetrical oblique reinforcing ribs 11 are fixedly connected to the bottom of the inner cavity of the grouting sealing block 6. The two oblique reinforcing ribs 11 are fixedly connected to the bottom of the surface of the limiting sleeve 9 on opposite sides. Side support ribs 12 are fixedly connected to the top and bottom of the two connecting reinforcing ribs 10. The end of the side support rib 12 away from the connecting reinforcing rib 10 is fixedly connected to the oblique reinforcing rib 11 and the transverse tie rib 13 respectively. Through the setting of the side support rib 12, the side support rib 12 is connected to the connecting reinforcing rib 10 and the oblique reinforcing rib 11. The transverse tie bars 13 work together to provide a stable support base for the three components, which can help disperse stress, allow the connecting reinforcing bars 10 to transmit node stress more efficiently, enhance the diagonal stress stability of the diagonal reinforcing bars 11, and improve the transverse tie stiffness of the transverse tie bars 13. The top of the grouting sealing block 6 has two symmetrical transverse tie bars 13 fixedly connected. The two transverse tie bars 13 are fixedly connected to the top of the surface of the limiting sleeve 9. The top of the two transverse tie bars 13 is fixedly connected to the diagonal anchor bars 14. The end of the two diagonal anchor bars 14 away from the transverse tie bars 13 is fixedly connected to the surface of the reinforcing bar 8.

[0014] Working Principle: During the construction phase, according to design requirements, steel bars 8 are precisely embedded in the concrete base 1 to ensure the position and spacing of the steel bars 8 meet assembly requirements, thus completing the foundation positioning of the base and steel bars. Subsequently, the prefabricated assembled wall panel 2 is hoisted. A grouting channel 4 is pre-installed within the wall panel. During hoisting, the grouting channel 4 is precisely inserted into the cavity of the steel bar 8. A limiting sleeve 9 is used to connect the steel bar 8, initially restricting its displacement within the channel. Then, by welding or mechanically connecting the connecting reinforcing bar 10 and the transverse tie bar 13 to the limiting sleeve 9, a reinforced connection system between the steel bar 8 and the grouting channel 4 is constructed. 0. Strengthen the vertical connection strength, and the horizontal tie bar 13 improves the horizontal tie stiffness. Together with the side support rib 12, they work together to disperse stress and ensure the stability of the relative position of the steel bar 8 and the channel. Then, grouting is carried out. The concrete grout is injected into the grouting channel 4 through the grouting equipment. The grout flows into the inner cavity of the bottom grouting sealing block 6 through the channel due to its own fluidity. It fills the gap between the steel bar 8 and the limiting sleeve 9, as well as the structural gap in the grouting sealing block 6. The connecting sleeve 7 limits the grouting sealing block 6 to prevent it from shifting due to the impact of grouting. The diagonal reinforcing bar 11 helps to optimize the grout. After the grout solidifies and hardens, the prefabricated wall panel 2 and the concrete base 1 are firmly connected.

[0015] In summary: This prefabricated wall panel, which also serves as a grouting channel, fixes multiple reinforcing bars 8 to the top of the concrete base 1. The grouting channel 4 is fixed inside the prefabricated wall panel 2. Through the coordinated use of the limiting sleeve 9, connecting reinforcing bars 10, and transverse tie bars 13, the position of the reinforcing bars 8 is stable when the grouting channel 4 and the reinforcing bars 8 are connected and fixed. Finally, concrete grout is injected into the inner cavity of the grouting channel 4 and flows into the inner cavity of the entire grouting sealing block 6. At this time, the gap between the reinforcing bars 8 and the limiting sleeve 9 is also filled by the concrete grout. This achieves the purpose of positioning and reinforcing the structure, ensuring the stable connection between the grouting channel and the reinforcing bars, avoiding relative displacement, ensuring the grouting is dense, improving the connection strength between the wall panel and the structure, facilitating installation, and enhancing the overall integrity and stability of the wall panel.
