Prefabricated wallboard secondary beam structure and construction process

Abstract

This invention discloses a precast wall panel secondary beam structure and construction process, belonging to the field of building construction technology. It includes a wall panel and a secondary beam. The upper surface of the wall panel is provided with a groove, the size of which is adapted to the secondary beam. A flat-pressing component is provided on the inner wall of the wall panel. In this invention, by providing the flat-pressing component, during the process of the secondary beam being placed into the groove, the secondary beam will compress a moving rod. The moving rod moves inward into the wall panel during compression. At this time, the moving rod will drive a blocking block to move via a lifting rod. As the blocking block moves backward, it will also move downward within the lifting groove. When the blocking block loses its obstruction of the moving block, the compression spring will push the pressure plate towards one side of the wall panel via the moving block, thereby causing the pressure plate to tightly press the secondary beam into the groove. This allows for quick alignment of the threaded holes on the reinforcing plate with the threaded holes on the wall panel, while simultaneously improving the connection between the secondary beam and the wall panel, thus enhancing the stability between the wall panel and the secondary beam.

Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a precast wall panel secondary beam structure and construction process. Background Technology

[0002] Secondary beams are located above the main beams and mainly serve to transfer loads. The length of the steel bars inside the secondary beam extending into the main beam only needs to meet the anchorage length. The anchorage length of the steel bars is independent of the span of the beam. In most cases, secondary beams are needed in building construction to improve the stability of the building.

[0003] When fixing secondary beams to building wall panels, the overall manufacturing and installation steps of the secondary beams are relatively complicated and prone to errors, resulting in instability between the secondary beams and wall panels, which can lead to corresponding dangers. This does not conform to the concept of convenience, safety and efficiency in the construction field. Therefore, a prefabricated wall panel secondary beam structure and construction process is provided. Summary of the Invention

The other end of the lifting rod extends to the outside of the lifting groove. A blocking block is fixedly installed at the other end of the lifting rod. The blocking block is a triangular block, and one end of the blocking block extends into the moving groove.

[0013] As a further description of the above technical solution:

[0014] The reinforcement component includes a sliding groove. Sliding grooves are provided on both inner walls of the secondary beam. A telescopic spring is fixedly installed on the inner wall of the sliding groove. A slider is fixedly installed on one end of the telescopic spring. The side wall of the slider is slidably connected to the inner wall of the sliding groove.

[0015] As a further description of the above technical solution:

[0016] A reinforcing plate is fixedly installed on the other side wall of the slider. Both the reinforcing plate and the side wall of the wall panel are provided with threaded holes. Multiple telescopic plates are fixedly installed on the side wall of the slider, and one end of the multiple telescopic plates is fixedly connected to the inner wall of the slide groove.

[0017] As a further description of the above technical solution:

[0018] A straight threaded connector and a reinforcing bar are fixedly installed on the inner wall of the wall panel. One end of the reinforcing bar extends to the outside of the upper surface of the groove, and one end of the straight threaded connector extends to the outside of the side wall of the wall panel. An insertion hole is provided on the lower surface of the secondary beam, and the size of the insertion hole is compatible with that of the reinforcing bar.

[0019] As a further description of the above technical solution:

[0020] An embedded column is fixedly installed at one end of the secondary beam, and an embedded hole is provided at the other end of the secondary beam. The size of the embedded column and the embedded hole are adapted to each other. Connecting grooves are provided on both the upper and lower surfaces of the secondary beam. A connecting rod is fixedly installed at the other end of the secondary beam, and the size of the connecting rod is adapted to the connecting groove.

[0021] As a further description of the above technical solution:

[0022] The reinforcing plate is made of high-strength steel plate, the connecting rod and the embedded column are both formed by concrete casting, and high-strength steel bars are fixedly installed inside. The pressure plate and the multi-section telescopic plate are both made of aluminum plate, and the steel bars are high-strength steel bars.

[0023] This invention also discloses a construction process for a precast wall panel secondary beam structure, comprising the following steps:

[0024] S1. Align the insertion hole below the secondary beam with the exposed reinforcing bar on the upper surface of the slot, and then slowly insert the secondary beam into the slot so that the secondary beam contacts the upper surface of the slot. Make slight adjustments to align the threaded hole on the reinforcing plate with the threaded hole on the side wall of the wall panel.

[0025] S2. During the process of placing the secondary beam into the slot, the secondary beam will squeeze the moving rod. Since one end of the moving rod is inclined, the moving rod will move into the wall panel when squeezed. At this time, the moving rod will drive the blocking block to move through the lifting rod. Since the blocking block is a triangular block and the inclined surface is in contact with the moving block, and since the lifting rod is movable in the lifting groove of the moving rod through the pressing spring, it will also move downward in the lifting groove when the blocking block moves backward. When the blocking block loses its obstruction to the moving block, the pressing spring will push the pressure plate to one side of the wall panel through the moving block, thereby making the pressure plate press the secondary beam tightly into the slot. Then, the reinforcement plate is connected to the wall panel using high-strength bolts.

[0026] S3. Then, install one end of the external reinforcing bar onto a connector that engages with the thread on the inner wall of the straight threaded connector, and fix the external reinforcing bar to the straight threaded connector. At this time, the secondary beam and the wall panel are firmly connected together.

[0027] S4. When splicing the secondary beams, insert the embedded column at one end of another secondary beam into the embedded hole at the other end of the fixed secondary beam, and then rivet the connecting rod to the connecting groove to make the splicing of the two secondary beams more stable. The reinforcing plate can slide in the groove on the side wall of the secondary beam. The telescopic spring in the groove allows the reinforcing plate to fit tightly with wall panels of different thicknesses through the slider. At the same time, multiple telescopic plates cover the part exposed in the groove to reduce the contact between the telescopic spring and the air.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In this invention, by setting up a flat pressing component, during the process of the secondary beam being placed into the slot, the secondary beam will compress the moving rod. Since one end of the moving rod is inclined, the moving rod will move inward into the wall panel when compressed. At this time, the moving rod will drive the blocking block to move through the lifting rod. Since the blocking block is a triangular block and the inclined surface fits against the moving block, and since the lifting rod is movable in the lifting groove of the moving rod through the pressing spring, it will also move downward in the lifting groove when the blocking block moves backward. When the blocking block loses its obstruction of the moving block, the pressing spring will push the pressure plate to one side of the wall panel through the moving block, thereby making the pressure plate press the secondary beam tightly into the slot. This can quickly align the threaded holes on the reinforcing plate with the threaded holes on the wall panel, while improving the connection between the secondary beam and the wall panel, thereby improving the stability between the wall panel and the secondary beam.

[0030] 2. In this invention, a reinforcing assembly is provided, and a reinforcing plate is connected to the wall panel using high-strength bolts. The reinforcing plate can slide in a groove on the side wall of the secondary beam. The telescopic spring in the groove allows the reinforcing plate to fit tightly with wall panels of different thicknesses through a slider. At the same time, multiple telescopic plates cover the part exposed in the groove, reducing the contact between the telescopic spring and the air. The assembly method is simple and convenient, which facilitates the assembly between the secondary beam and the wall panel, thereby shortening the construction period and reducing the construction cost.

[0031] 3. In this invention, by setting embedded columns and connecting rods, when splicing secondary beams, the embedded column at one end of another secondary beam is inserted into the embedded hole at the other end of the fixed secondary beam, and then the connecting rod and connecting groove are riveted together, thereby making the splicing of the two secondary beams more stable, facilitating the splicing between secondary beams, improving the load-bearing capacity and seismic resistance of the secondary beams, and thus improving the load capacity of the secondary beams and the building quality.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1-7 The present invention provides a technical solution: a prefabricated wall panel secondary beam structure, including a wall panel 1 and a secondary beam 2, wherein the upper surface of the wall panel 1 is provided with a groove 5, the size of the groove 5 is adapted to the secondary beam 2, a flat pressing component 6 is provided on the inner wall of the wall panel 1, and a reinforcing component 7 is provided on the side wall of the secondary beam 2.

[0043] The flattening assembly 6 includes a moving groove 61 and a moving rod 65. The upper surface of the wall panel 1 is provided with the moving groove 61. A compression spring 62 is fixedly installed on the inner wall of the moving groove 61. A moving block 63 is fixedly installed at one end of the compression spring 62. The side wall of the moving block 63 is slidably connected to the inner wall of the moving groove 61. A pressure plate 64 is fixedly installed on the upper surface of the moving block 63. The moving rod 65 is slidably connected to the inner wall of the wall panel 1. One end of the moving rod 65 extends to the outside of the side wall of the groove 5, and one end of the moving rod 65 is inclined. The other end of the moving rod 65 extends into the wall panel 1. A lifting groove 66 is provided on the side wall of the moving rod 65. A pressing spring 67 is fixedly installed on the inner wall of the lifting groove 66. A lifting rod 68 is fixedly installed on one end of the pressing spring 67. One end of the lifting rod 68 is slidably connected to the inner wall of the lifting groove 66. The other end of the lifting rod 68 extends out of the lifting groove 66. A blocking block 69 is fixedly installed on the other end of the lifting rod 68. The blocking block 69 is a triangular block. One end of the blocking block 69 extends into the moving groove 61.

[0044] The specific implementation is as follows: During the process of the secondary beam 2 being placed into the slot 5, the secondary beam 2 will squeeze the moving rod 65. Since one end of the moving rod 65 is inclined, the moving rod 65 will move into the interior of the wall panel 1 when squeezed. At this time, the moving rod 65 will drive the blocking block 69 to move through the lifting rod 68. Since the blocking block 69 is a triangular block and its inclined surface is in contact with the moving block 63, and since the lifting rod 68 is movable in the lifting groove 66 of the moving rod 65 through the pressing spring 67, it will also move downward in the lifting groove 66 when the blocking block 69 moves backward. When the blocking block 69 loses its obstruction to the moving block 63, the pressing spring 62 will push the pressure plate 64 to one side of the wall panel 1 through the moving block 63, thereby making the pressure plate 64 press the secondary beam tightly into the slot 5.

[0045] The reinforcing component 7 includes a sliding groove 71. Sliding grooves 71 are provided on both inner walls of the secondary beam 2. A telescopic spring 72 is fixedly installed on the inner wall of the sliding groove 71. A slider 73 is fixedly installed on one end of the telescopic spring 72. The side wall of the slider 73 is slidably connected to the inner wall of the sliding groove 71. A reinforcing plate 74 is fixedly installed on the other side wall of the slider 73. Threaded holes are provided on both the reinforcing plate 74 and the side wall of the wall panel 1. Multiple telescopic plates 75 are fixedly installed on the side wall of the slider 73. One end of the multiple telescopic plates 75 is fixedly connected to the inner wall of the sliding groove 71.

[0046] The specific implementation is as follows: the reinforcing plate 74 is connected to the wall panel 1 using high-strength bolts. The reinforcing plate 74 can slide in the groove 71 on the side wall of the secondary beam 2. The telescopic spring 72 in the groove 71, through the slider 73, allows the reinforcing plate 74 to fit tightly with the wall panel 1 of different thicknesses. At the same time, multiple telescopic plates 75 cover the part exposed by the groove 71, reducing the contact between the telescopic spring 72 and the air.

[0047] A straight threaded connector 3 and a reinforcing bar 4 are fixedly installed on the inner wall of the wall panel 1. One end of the reinforcing bar 4 extends to the outside of the upper surface of the groove 5, and one end of the straight threaded connector 3 extends to the outside of the side wall of the wall panel 1. An insertion hole 11 is provided on the lower surface of the secondary beam 2, and the size of the insertion hole 11 is compatible with that of the reinforcing bar 4.

[0048] The specific implementation is as follows: Align the insertion hole 11 below the secondary beam 2 with the exposed reinforcing bar 4 on the upper surface of the slot 5, and then slowly insert the secondary beam 2 into the slot 5 so that the secondary beam 2 contacts the upper surface of the slot 5. Make slight adjustments so that the threaded hole on the reinforcing plate 74 is aligned with the threaded hole on the side wall of the wall panel 1. Then install one end of the external reinforcing bar with the threaded connector on the inner wall of the straight threaded connector 3, and fix the external reinforcing bar to the straight threaded connector 3. At this time, the secondary beam 2 and the wall panel 1 are firmly connected together.

[0049] One end of the secondary beam 2 is fixedly equipped with an embedded column 10, and the other end of the secondary beam 2 is provided with an embedded hole 12. The size of the embedded column 10 and the embedded hole 12 are adapted to each other. Both the upper and lower surfaces of the secondary beam 2 are provided with connecting grooves 8. The other end of the secondary beam 2 is fixedly equipped with a connecting rod 9. The size of the connecting rod 9 and the connecting groove 8 are adapted to each other. The reinforcing plate 74 is made of high-strength steel plate. The connecting rod 9 and the embedded column 10 are both formed by concrete casting and have high-strength steel bars fixedly installed inside. The pressure plate 64 and the multi-section telescopic plate 75 are both made of aluminum plate. The steel bar 4 is a high-strength steel bar.

[0050] The specific implementation is as follows: When splicing the secondary beam 2, the embedded column 10 at one end of another secondary beam 2 is inserted into the embedded hole 12 at the other end of the fixed secondary beam 2, and then the connecting rod 9 is riveted to the connecting groove 8, so that the splicing of the two secondary beams 2 is more stable.

[0051] This invention also discloses a construction process for a precast wall panel secondary beam structure, comprising the following steps:

[0052] S1. Align the insertion hole 11 below the secondary beam 2 with the exposed steel bar 4 on the upper surface of the slot 5, and then slowly put the secondary beam 2 into the slot 5 so that the secondary beam 2 contacts the upper surface of the slot 5. Make slight adjustments so that the threaded hole on the reinforcing plate 74 is aligned with the threaded hole on the side wall of the wall panel 1.

[0053] S2. During the process of placing the secondary beam 2 into the slot 5, the secondary beam 2 will squeeze the moving rod 65. Since one end of the moving rod 65 is inclined, the moving rod 65 will move into the interior of the wall panel 1 when squeezed. At this time, the moving rod 65 will drive the blocking block 69 to move through the lifting rod 68. Since the blocking block 69 is a triangular block and the inclined surface is in contact with the moving block 63, and since the lifting rod 68 is movable in the lifting groove 66 of the moving rod 65 through the pressing spring 67, the blocking block 69 will also move downward in the lifting groove 66 when it moves backward. When the blocking block 69 loses its obstruction to the moving block 63, the pressing spring 62 will push the pressure plate 64 to one side of the wall panel 1 through the moving block 63, so that the pressure plate 64 will press the secondary beam tightly into the slot 5. Then, the reinforcing plate 74 is connected to the wall panel 1 using high-strength bolts.

[0054] S3. Then install one end of the external steel bar with a connector that engages with the thread on the inner wall of the straight thread connector 3, and fix the external steel bar to the straight thread connector 3. At this time, the secondary beam 2 and the wall panel 1 are firmly connected together.

[0055] S4. When splicing the secondary beam 2, insert the embedded column 10 at one end of the other secondary beam 2 into the embedded hole 12 at the other end of the fixed secondary beam 2, and then rivet the connecting rod 9 to the connecting groove 8, so that the splicing of the two secondary beams 2 is more stable. The reinforcing plate 74 can slide in the groove 71 on the side wall of the secondary beam 2. The telescopic spring 72 in the groove 71, through the slider 73, makes the reinforcing plate 74 fit tightly with the wall panel 1 of different thicknesses. At the same time, the multi-section telescopic plate 75 covers the part exposed by the groove 71, reducing the contact between the telescopic spring 72 and the air.

[0056] Working principle: Align the insertion hole 11 below the secondary beam 2 with the exposed reinforcing bar 4 on the upper surface of the slot 5, and then slowly insert the secondary beam 2 into the slot 5, so that the secondary beam 2 contacts the upper surface of the slot 5. Make slight adjustments to align the threaded hole on the reinforcing plate 74 with the threaded hole on the side wall of the wall panel 1. During the process of inserting the secondary beam 2 into the slot 5, the secondary beam 2 will compress the moving rod 65. Since one end of the moving rod 65 is inclined, the moving rod 65 will move inward into the wall panel 1 when compressing. At this time, the moving rod 65 will drive the blocking block 69 to move through the lifting rod 68. Since the blocking block 69 is a triangular block and its inclined surface fits against the moving block 63, and since the lifting rod 68 is movable in the lifting groove 66 of the moving rod 65 through the pressing spring 67, the blocking block 69 will also move downward in the lifting groove 66 when it moves backward. When the blocking block 69 loses its obstruction to the moving block 63, the pressing spring 62 will release the pressure through the moving block 63. The plate 64 is pushed to one side of the wall panel 1, thereby pressing the secondary beam tightly into the groove 5. Then, the reinforcing plate 74 is connected to the wall panel 1 using high-strength bolts. Then, one end of the external steel bar is installed with a joint that engages with the thread on the inner wall of the straight threaded joint 3, and the external steel bar is fixedly connected to the straight threaded joint 3. At this time, the secondary beam 2 and the wall panel 1 are firmly connected together. When splicing the secondary beam 2, the embedded column 10 at one end of another secondary beam 2 is inserted into the embedded hole 12 at the other end of the fixed secondary beam 2. Then, the connecting rod 9 is riveted to the connecting groove 8, thereby making the splicing of the two secondary beams 2 more stable. The reinforcing plate 74 can slide in the sliding groove 71 on the side wall of the secondary beam 2. The telescopic spring 72 in the sliding groove 71, through the slider 73, allows the reinforcing plate 74 to fit tightly with the wall panel 1 of different thicknesses. At the same time, the multi-section telescopic plate 75 covers the part exposed by the sliding groove 71, reducing the contact between the telescopic spring 72 and the air.

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 inventive concept of the present invention, should be covered within the scope of protection of the present invention.

At the same time, the multi-section telescopic plate (75) covers the part exposed by the groove (71) to reduce the contact between the telescopic spring (72) and the air.
