Description

TECHNICAL FIELD

[0001] The present application relates to the field of building wall panels, and more particularly to a self-adjusting beam-wall integrated external wall panel, production process and construction method. BACKGROUND

[0002] As an innovative solution for the maintenance system of steel frame structure buildings, the prefabricated external wall panel effectively solves the limitations of traditional wall maintenance methods through factory prefabrication production and modular installation technology. Compared with the problems such as hollowing, cracking and window hole cracking of the filling wall body built on site, the prefabricated external wall panel adopts standardized design to complete the integrated forming of the wall structure, insulation layer and decorative surface layer in the factory, which significantly improves the durability and air tightness of the building envelope system. At the same time, aiming at the pain points of high energy consumption and complex process of traditional external wall, the prefabricated technology realizes the balance between lightweight and efficient construction through optimizing material selection and connection node design.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Please see Figures 1-7 In one embodiment of the present invention, a self-adjusting beam-wall exterior wall panel includes a composite beam 1 and a prefabricated wall panel 2 hinged to it by a plurality of connectors 3. The composite beam 1 is used to fix it to the frame column 6 of the building. The composite beam 1 includes a steel beam 101 and an inner prefabricated filling block 102 filled in the cavity of the steel beam 101 facing the interior. A plurality of semi-embedded tie bars 4 are pre-embedded in the prefabricated wall panel 2. The semi-embedded tie bars 4 extend into the cavity of the steel beam 101 facing the exterior. The connectors 3 include a central block 301. A plurality of anchor bars 5 pre-embedded in the prefabricated wall panel 2 are fixedly connected to the lower end of the central block 301. A pair of end blocks 302 abut against both sides of the central block 301. The upper end of the end blocks 302 is fixedly connected to the lower end face of the steel beam 101. A hinge bolt 303 slides through the end blocks 302. The hinge bolt 303 extends into the central block 301 and is threadedly fixed to the central block 301.

[0043] Compared to traditional external wall panels, this invention uses connector 3 to achieve a hinged connection between the composite beam 1 and the precast wall panel 2, replacing the traditional method of independently setting external wall panels and frame beams. This reduces the number of installation components. Furthermore, by filling the steel beam 101 with precast filling blocks 102, the amount of concrete poured on-site is reduced, improving the overall building installation efficiency during assembly. At the same time, the precast wall panel 2 is connected to the composite beam 1 through connector 3. During assembly, the verticality of the precast wall panel 2 is adjusted using its own weight, replacing the traditional method of adjusting integral wall panels by using external equipment such as cranes. This simplifies the adjustment operation and improves the efficiency and quality of wall panel verticality adjustment.

[0044] Please see Figure 7 The precast filling block 102 is embedded with a steel cage 9, and the precast wall panel 2 is embedded with a steel cage 13. The steel cage 9 is fixedly connected to the inner wall of the steel beam 101. The semi-embedded tie bar 4 and the anchor bar 5 are both fixedly connected to the steel cage 13. The part of the semi-embedded tie bar 4 located in the steel beam 101 is fixedly connected with a transverse tie bar.

[0045] Specifically, the connector 3 is fixed to the steel cage 13 inside the precast wall panel 2 by the anchor bar 5, thereby improving the connection stability between the connector 3 and the precast wall panel 2.

[0046] Please seeFigure 3 The end block 302 has a hinge hole 3021 through which the hinge bolt 303 passes. The front end of the hinge bolt 303 has an external thread 3031 that mates with the threaded hole 3011. The part of the hinge bolt 303 away from the external thread 3031 slides against the inner wall of the hinge hole 3021. The hinge hole 3021 is a cylindrical hole with a circular cross-section.

[0047] Specifically, the hinge bolt 303 is fixed to the center block 301, and the end block 302 rotates on the hinge bolt 303.

[0048] Please see Figure 4 The cross-section of the hinge hole 3021 is a vertical waist-shaped hole.

[0049] Specifically, the hinge bolt 303 can move vertically up and down within the hinge hole 3021, which has a vertical waist-shaped cross-section, so that the precast wall panel 2 can rotate back and forth and move up and down during adjustment, further improving the adjustable range of the precast wall panel 2 and improving the adjustment quality of the precast wall panel 2.

[0050] Please see Figure 7 A manufacturing process for a self-adjusting beam-wall integrated exterior wall panel includes the following steps:

[0051] Step 1: Weld the reinforcing cage 9 into the inner cavity of one side of the steel beam 101;

[0052] Step 2: First, fabricate the steel cage 2 13 for the precast wall panel 2. Then, weld the connector 3 to the lower end face of the steel beam 101. Next, weld the two ends of the anchor bar 5 to the connector 3 and the steel cage 2 13 respectively. Finally, weld multiple semi-buried tie bars 4 to the steel cage 2 13 and weld the transverse tie bars to each semi-buried tie bar 4 to obtain the combined welded frame.

[0053] It should be noted that the welding of connector 3 includes the following sub-steps:

[0054] A1. Weld and fix the center block 301 to the lower end face of the steel beam 101;

[0055] A2, and then fix the end block 302 to both sides of the center block 301 by means of hinge bolts 303;

[0056] A3. Weld and fix the anchor bar 5 to the lower end face of the center block 301.

[0057] Step 3: Place the combined welding frame in the mold table and precast the precast wall panel 2 and the inner precast filling block 102 to obtain the self-adjusting beam wall outer wall panel.

[0058] Compared with traditional exterior wall panels, the present invention obtains precast wall panels 2 and combined beams 1 that are hinged to the precast wall panels 2 by integral casting, and further reduces the amount of on-site casting by casting the inner precast filling blocks 102, thereby improving the production and assembly efficiency.

[0059] Please see Figures 5-7 A construction method for a self-adjusting beam-wall integrated exterior wall panel includes the following steps:

[0060] S1. The self-adjusting beam wall panel is hoisted to the inside of the frame column 6 by a crane. Then, the steel beam 101 is fixedly connected to the frame columns 6 on both sides, and the hoisting ropes are unloaded.

[0061] S2, push the precast wall panel 2, and use the self-weight of the precast wall panel 2 and the hinge action of the connector 3 to adjust the verticality of the precast wall panel 2, so that the precast wall panel 2 can be spliced ​​and fixed with the adjacent wall panel.

[0062] S3, formwork is erected on both sides of the precast wall panel 2, and concrete is poured on site after the formwork is erected. After pouring, cast-in-place end column 7 is formed between the precast wall panel 2 and the frame column 6. Cast-in-place guide wall 8 is formed above the precast wall panel 2, thus completing the installation of the self-adjusting beam wall and the exterior wall panel.

[0063] Please see Figure 1 and Figure 2 The precast wall panel 2 has a slot 201 at the lower end, and the cast-in-place guide wall 8 includes a strip 801, which is engaged between the precast wall panel 2 and the adjacent cast-in-place guide wall 8.

[0064] Specifically, improve the splicing quality and waterproofing quality of adjacent exterior wall panels.

[0065] In another embodiment of the invention, please refer to Figures 7-10 A self-adjusting beam wall integral exterior wall panel, wherein a sleeve 11 is sleeved on the outer end of a steel beam 101, and a splicing beam 10 is sleeved on the end of the sleeve 11 away from the steel beam 101. The sleeve 11 is fixedly connected to the steel beam 101 and the splicing beam 10 respectively by multiple locking bolts 12. The splicing beam 10 is fixedly connected to the frame column 6. The sleeve 11 has a ring structure and covers the outside of the steel beam 101.

[0066] Specifically, when installing the exterior wall panel, the sleeve 11 is first sleeved onto the splicing beam 10, and then the exterior wall panel of the self-adjusting beam wall is hoisted between the splicing beam 10. Then, the sleeve 11 is manually pushed to slide to the splicing joint between the splicing beam 10 and the steel beam 101, and then the locking bolt 12 is installed to connect and fix the three together.

[0067] Compared to traditional connection methods, this invention utilizes a sleeve 11 fitted onto the splicing beam 10. During installation, the sliding sleeve 11 enables rapid docking and positioning of the steel beam 101 and the splicing beam 10, followed by fixation with locking bolts 12. This achieves rapid positioning and fixation of the self-adjusting beam-wall integrated exterior wall panel, improving installation efficiency. Furthermore, the ring-shaped sleeve 11, located at the joint between the steel beam 101 and the splicing beam 10, enhances the stability and load-bearing capacity of the connection. Additionally, the sleeve improves the horizontality of the composite beam, facilitating subsequent adjustment of the wall panel's verticality and further enhancing the accuracy of wall panel adjustment.

[0068] Please see Figure 7 and Figure 10 Both steel beam 101 and splicing beam 10 are H-beams, and the sleeve 11 is an I-shaped ring frame with a chamfered surface 1102 at the opening of the sleeve 11.

[0069] Specifically, the I-shaped connector 11 provides good support and limiting effect on both the inner and outer sides of the steel beam 101 and the spliced ​​beam 10 made of H-beams, further improving the stability and load-bearing capacity of the connection between the steel beam 101 and the spliced ​​beam 10. The chamfered surface 1102 set at the opening of the connector 11 facilitates the sliding connection between the connector 11 and the steel beam 101.

[0070] Please see Figure 9 and Figure 10 The sleeve 11 has multiple through holes 1101, and the steel beam 101 and the splicing beam 10 have bolt holes 103 and 1001 respectively, which are opposite to the through holes 1101.

[0071] Specifically, the locking bolt 12 and the sleeve 11 work together to provide multi-level load bearing for the steel beam 101 and the spliced ​​beam 10, replacing the traditional bolt connection method where the weight of the beam is mainly concentrated at the bolt. This reduces the vertical shear force on the locking bolt 12 and further improves the connection stability and load bearing capacity.

[0072] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
