Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically a construction structure for a standardized steel keel for shear wall corner walls. Background Technology

[0002] In modern construction engineering, the application of fair-faced concrete structures is becoming increasingly widespread. However, the construction effect of traditional steel pipe scaffolding formwork support can no longer meet the standards of fair-faced concrete. Furthermore, in concrete structure engineering, the cost of formwork support system erection accounts for a significant proportion. Statistics show that the labor input for formwork support system construction in China accounts for approximately 30% to 50% of the total labor in concrete structure construction, and the construction time required for formwork support system construction accounts for approximately 50% to 60% of the total construction period for concrete structure projects. In the traditional formwork support erection process for shear wall corner walls, steel pipes and timber are typically used as the main and secondary back ribs (keels) of the formwork. This formwork support is simple to erect, easy to assemble and disassemble, and can meet the dimensions of various buildings, making it highly applicable. However, the rigidity of the shear wall corner wall formwork system is poor, and the operators have a high degree of arbitrariness in construction, often resulting in phenomena such as "formwork running away" and "formwork bulging" during concrete pouring, thus making it difficult to guarantee construction quality. Therefore, in order to solve the problems of difficulty in erecting formwork support systems for shear wall corner walls and waste of labor resources, there is an urgent need for a new type of standardized steel keel construction structure for shear wall corner walls to solve the current problems. Summary of the Invention

[0003] The purpose of this invention is to provide a construction structure for a standardized steel keel for shear wall corner walls, so as to solve the problems mentioned in the background art.

[0004] The technical solution of the present invention is: a construction structure for a standardized steel keel for a shear wall corner wall, comprising multiple square steel bars, all of which are arranged on the side of the shear wall corner wall, and the length of each square steel bar is the same as the length of the shear wall corner wall. The ends of two oppositely arranged square steel bars in the shear wall corner wall are fixedly connected by connecting bolts and connecting components. Parallel square steel bars in the shear wall corner wall are fixedly connected by locking components, and the locking components are fixedly connected to the shear wall corner wall by through-wall bolts.

[0005] Furthermore, one end of the square steel is provided with a first through hole, and the other end of the square steel is provided with a fourth through hole.

At the same time, a second through hole is provided on the fixed block, and a third through hole is provided on the movable block. The first through hole and the second through hole, as well as the first through hole and the third through hole, are located on the same plane.

[0008] Furthermore, the first, second, and third through holes are all threaded inside.

[0009] Furthermore, the fixed block and the movable block are positioned between two parallel fourth perforations.

[0010] Furthermore, the locking assembly includes multiple connecting frames arranged opposite each other. The connecting frames are sleeved on the outside of the square steel. The ends of two adjacent connecting frames are fixedly connected by fixing bolts and locking blocks. The middle parts of two adjacent connecting frames are fixedly connected by connecting blocks. The connecting blocks are also connected to through-wall bolts.

[0011] Furthermore, the connecting frames have end holes on their opposite sides, and adjacent connecting frames are fixedly connected by fixing bolts passing through the end holes and locking blocks.

[0012] Furthermore, the connecting frame has an upper through hole and a side through hole in the middle of its opposite sides. The upper through hole is located at the upper end of the side through hole, and the upper through hole and the side through hole are perpendicular to each other. The interior of the upper through hole and the interior of the side through hole are connected. The middle part of the connecting frame is fixedly connected to the connecting block by a connecting bolt passing through the upper through hole or the side through hole.

[0013] Furthermore, a connecting hole is provided in the middle of the connecting block, and the connecting block and the corner wall of the shear wall are fixedly connected by through-wall bolts passing through the connecting hole.

[0021] refer to Figures 1-4 This embodiment provides a construction structure for a standardized steel keel for a shear wall corner wall. This structure uses 40×40×3 square steel 1 as the main and secondary back ribs of the template. Specifically, the structure includes multiple square steel 1s, all of which are positioned on the side of the shear wall corner wall, and the length of each square steel 1 is the same as the length of the shear wall corner wall. Specifically, the ends of two oppositely positioned square steel 1s on the shear wall corner wall are fixedly connected by connecting bolts and connecting components 3. Parallel square steel 1s on the shear wall corner wall are fixedly connected by locking components 5, and the locking components 5 are fixedly connected to the shear wall corner wall by through-wall bolts 6.

[0022] In this embodiment, a first through hole 2 is provided at one end of a square steel 1 arranged opposite to each other, and a fourth through hole 4 is provided at the end of another square steel 1 arranged opposite to each other. The first through hole 2 and the fourth through hole 4 are arranged perpendicular to each other. The connecting component 3 passes through the fourth through hole 4, and the connecting bolt passes through the first through hole 2 and is fixedly connected to the connecting component 3. Specifically, the connecting component 3 includes a movable frame 301 and a fixed frame 304. The movable frame 301 is disposed on the side of the fixed frame 304, and the end of the movable frame 301 is disposed inside the end of the fixed frame 304. At the same time, the ends of the movable frame 301 and the fixed frame 304 are both disposed inside the fourth through hole 4. Furthermore, a movable block 305 is provided in the middle of the inward-facing side of the movable frame 301, and a fixed block 302 is provided in the middle of the inward-facing side of the fixed frame 304. The fixed block 302 and the movable block 305 are arranged opposite each other, with the fixed block 302 located outside the movable block 305. A second through hole 303 is provided on the fixed block 302, and a third through hole 306 is provided on the movable block 305. The first through hole 2 and the second through hole 303, as well as the first through hole 2 and the third through hole 306, are located on the same plane. It is worth noting that the first through hole 2, the second through hole 303, and the third through hole 306 are all threaded. The fixed block 302 and the movable block 305 are positioned between two parallel fourth through holes 4. In other words, a connecting bolt passes through the first through hole 2, the second through hole 303, and the third through hole 306 to securely connect the ends of the two oppositely arranged square steel bars 1.

[0023] Furthermore, the locking assembly 5 includes multiple connecting frames 506 arranged opposite to each other. Each connecting frame 506 is fitted over the square steel 1. The ends of two adjacent connecting frames 506 are fixedly connected by fixing bolts 507 and locking blocks 508, and the middle portions of two adjacent connecting frames 506 are fixedly connected by connecting blocks 504. Specifically, each connecting frame 506 has an end through hole 501 at its opposite side end. Two adjacent connecting frames 506 are fixedly connected by fixing bolts 507 passing through the end through holes 501 and locking blocks 508. The connecting frame 506 has an upper through hole 502 and a side through hole 505 on its opposite sides. The upper through hole 502 is located above the side through hole 505, and the upper through hole 502 and the side through hole 505 are perpendicular to each other. The interiors of the upper through hole 502 and the side through hole 505 are connected. The middle part of the connecting frame 506 is fixedly connected to the connecting block 504 by a connecting bolt passing through the upper through hole 502 or the side through hole 505. Furthermore, the connecting block 504 has a connecting through hole 503 in its middle part. The connecting block 504 and the shear wall corner wall are fixedly connected by a through bolt 6 passing through the connecting through hole 503.

[0024] Specifically, the construction process of the standardized steel keel structure for the shear wall corner wall in this embodiment is as follows: Step 1: Arrange multiple square steel bars 1 on both sides of the shear wall corner according to the length of the wall, ensuring that the length of each square steel bar 1 is consistent with the wall, and then splice the square steel bars 1 using connecting components 3. Specifically: Align the first through hole 2 of one square steel 1 with the fourth through hole 4 of another square steel 1, and insert the movable frame 301 and the fixed frame 304 in the connecting assembly 3 into the two oppositely arranged fourth through holes 4 respectively. Then, pass the connecting bolts through the first through hole 2, the second through hole 303 and the third through hole 306 in sequence and tighten them to achieve the end fixed connection of the two square steel 1.

[0025] Step 2: Secure the parallel square steel bars 1 between the corner walls of the shear wall using locking components 5. Specifically: The connecting frame 506 is fitted over the square steel 1, and the ends of adjacent connecting frames 506 are fixed together using fixing bolts 507 and locking blocks 508. Then, the connecting frame 506 in the middle is connected and fixed using connecting blocks 504. At the same time, the connecting through holes 503 on the connecting blocks 504 are engaged with the embedded parts on the wall, and the connecting blocks are securely connected to the corner wall of the shear wall using through bolts 6.
