Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a reinforced support system for large-volume concrete construction. Background Technology

[0002] Currently, in the construction industry, the construction of large-volume concrete structures for hospitals, research institutes, and other institutions with special functional requirements such as self-waterproofing and radiation protection places high demands on the quality of concrete molding. Therefore, in order to ensure the construction and molding quality of large-volume concrete with special functional requirements, it is necessary to optimize, improve, and innovate on the basis of conventional large-volume concrete construction to improve the quality of concrete molding in this functional area.

[0003] In existing technologies, for the installation of support formwork for large-volume concrete, tie rod structures are generally used to connect and fix the formwork on both sides of the concrete wall. However, conventional formwork systems and methods cannot meet the requirements of weak support areas such as wall corners, areas prone to formwork bulging, and areas prone to formwork bursting. Therefore, in order to strengthen the support structure of weak support areas such as wall corners, areas prone to formwork bulging, and areas prone to formwork bursting, it is necessary to improve the existing formwork system to improve the overall molding quality of large-volume concrete. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a reinforced support system for the construction of large-volume concrete. By installing reinforced support devices in the formwork structure at weak support points such as wall corners, it ensures that weak support points such as corners, areas prone to formwork bulging, and areas prone to formwork bursting are effectively supported, thereby improving the overall molding quality of large-volume concrete.

[0005] This invention provides a reinforced support system for large-volume concrete construction, comprising formwork assemblies supported on both sides of a pre-designed concrete structure wall. Reinforcing support devices are installed on the formwork assemblies located at the internal and external corners of the concrete structure wall. Each reinforcing support device includes internal corner anchor rings on the two internal corner walls, external corner anchor rings on the two external corner walls, and hook-head tie rods positioned between the internal and external corner anchor rings and between the external corner anchor rings. The hook-head tie rods connect the perpendicularly positioned internal and external corner anchor rings and external corner anchor rings to form a diagonal tie structure.

[0006] Furthermore, the external corner anchor ring includes a first external corner anchor ring, a second external corner anchor ring, and a third external corner anchor ring installed on the same wall surface from far to near the corner. The internal corner anchor ring and the second external corner anchor ring are connected by the hook head to the tie rod to form a diagonal tie. The first external corner anchor ring and the third external corner anchor ring on the adjacent wall surface are connected by the hook head to the tie rod to form a diagonal tie structure.

[0007] Furthermore, the template assembly includes a template, a horizontal main rib disposed on the outside of the template, a vertical secondary rib disposed between the template and the horizontal main rib, a tie structure penetrating the template on both sides of the wall, and a support assembly disposed on the outside of the template for supporting the template. The horizontal main rib is a double-channel steel structure.

[0008] Furthermore, the tie structure includes tie rods and locking elements. The free end of the tie rod passes through the templates on both sides of the wall and then passes through the gap between adjacent vertical secondary ribs and the gap in the horizontal main rib structure in sequence. It is then locked to the horizontal main rib by the locking elements to form a tie structure.

[0009] Furthermore, one end of the internal corner anchor ring and the external corner anchor ring passes through the template and extends between the two side templates, and the other end of the internal corner anchor ring and the external corner anchor ring passes through the horizontal main rib and extends out. The ends of the internal corner anchor ring and the external corner anchor ring are provided with threaded sections.

[0010] Furthermore, both the inner corner anchor ring and the outer corner anchor ring are provided with a connecting structure at their ends. The connecting structure includes steel plates on both sides of the horizontal main rib width direction and nuts provided on the outer side of the steel plates that are threadedly connected to the ends of the inner corner anchor ring and the outer corner anchor ring.

[0011] Furthermore, the external corner anchor ring and the internal corner anchor ring, which are arranged in the same direction, are located on the same horizontal plane at the same height.

[0012] Furthermore, in the support reinforcement device, the tie rod of the diagonal bracing structure located at the outermost corner is interlocked with the tie rod in the tie structure by 300mm.

[0013] In summary, this application has at least one of the following beneficial effects: The reinforced support system for large-volume concrete construction of the present invention improves the formwork support structure of special functional areas by setting support reinforcement devices in the formwork structure of weak support parts such as wall corners, ensuring that weak support parts such as corners, parts prone to formwork expansion, and parts prone to formwork explosion are effectively supported, thereby improving the overall molding quality of large-volume concrete.

Detailed Implementation

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] This invention provides a reinforced support system for large-volume concrete construction, comprising formwork assemblies supported on both sides of a pre-designed concrete structure wall. Reinforcing support devices are installed on the formwork assemblies located at the internal and external corners of the concrete structure wall. The reinforcing support devices include internal corner anchor rings 12 on the two internal corner walls, external corner anchor rings on the two external corner walls, and hook-head tie rods 7 positioned between the internal and external corner anchor rings and between the external corner anchor rings. The hook-head tie rods 7 connect the mutually perpendicular internal corner anchor rings 12 and external corner anchor rings, and the mutually perpendicular external corner anchor rings, to form a diagonal tie structure.

[0021] This solution involves installing support reinforcement devices at weak points in the conventional formwork support system, such as wall corners. Hook-head tie rods 7 are used to connect mutually perpendicular internal corner anchor rings 12 and external corner anchor rings, forming a diagonal tie structure. This strengthens the tensile strength of the weak support points and prevents formwork bursting or bulging during subsequent concrete pouring, thereby improving the overall molding quality of large-volume concrete.

[0022] In this embodiment, the external corner anchor ring includes a first external corner anchor ring 6, a second external corner anchor ring 10, and a third external corner anchor ring 11 arranged on the same wall surface from far to near towards the corner. The internal corner anchor ring 12 and the second external corner anchor ring 10 are connected by the hook head to the tie rod 7 to form a diagonal tie. The first external corner anchor ring 6 and the third external corner anchor ring 11 on the adjacent wall surface are connected by the hook head to the tie rod 7 to form a diagonal tie structure. Figure 1As shown, six diagonal bracing structures are installed at the inside and outside corners of wall 1, with three on each side of the wall. Since the inside corner wall surface is smaller than the outside corner wall surface, an inside corner anchor ring 12 is installed on each side of the inside corner wall surface and the second outside corner anchor ring 10 on the adjacent side template of the opposite template is connected to the hook head tie rod 7 to form a diagonal bracing structure. In order to further enhance the tensile strength at the inside and outside corners, a first outside corner anchor ring 6 and a third outside corner anchor ring 11 are installed on each side of the outside corner wall surface, i.e., on the left and right sides of the second outside corner anchor ring 10. The first outside corner anchor ring 6 on this side wall surface and the third outside corner anchor ring 11 on the adjacent side wall surface are connected to the hook head tie rod 7 to form a diagonal bracing structure.

[0023] In this embodiment, the template assembly includes a template 2, a horizontal main rib disposed on the outside of the template, a vertical secondary rib disposed between the template and the horizontal main rib, a tie structure penetrating the templates on both sides of the wall, and a support assembly disposed on the outside of the template for supporting the template. The horizontal main rib is a double-channel steel structure. The tie structure includes tie rods and locking elements. The free end of the tie rods penetrates the templates on both sides of the wall and then passes through the gaps between adjacent vertical secondary ribs and the gaps in the horizontal main rib structure, and is locked to the horizontal main rib by the locking elements to form a tie structure.

[0024] In this embodiment, combined with Figure 1 and Figure 2 As shown, the horizontal main ribs are double-channel steel 4, and the vertical secondary ribs are square steel pipes 3. Setting horizontal main ribs and vertical secondary ribs on the outside of the formwork 2 is a common structure used in formwork support construction. The support components mainly provide lateral support for the formwork. The tie rods are precision-rolled threaded steel tie rods, and the locking parts are mountain-shaped clips 13. In this scheme, the formwork 2 uses 915mm×1830mm×15mm (thick) covered plywood; the support components use 40×40×2.5mm square steel pipes @150, and the vertical... Layout: The horizontal main ribs are made of two φ48×2.7mm ordinary steel pipes, arranged horizontally, and reinforced with φ14 water-stop tie rods (using 50mm×50mm×2mm steel water-stop rings). The vertical spacing of the tie rods is 300mm, the horizontal spacing is 300mm, and the bottom tie rod is 100mm away from the completed side wall concrete surface. The outer side of the side wall is supported at @3000mm, and when reinforcing the adjacent inner wall, additional steel pipes and top supports are used for horizontal mutual support at @1000mm.

[0025] In this embodiment, one end of the internal corner anchor ring 12 and the external corner anchor ring passes through the template and extends between the two side templates. The other end of the internal corner anchor ring 12 and the external corner anchor ring passes through the horizontal main rib and extends out. The ends of the internal corner anchor ring 12 and the external corner anchor ring are provided with threaded sections. The ends of the internal corner anchor ring and the external corner anchor ring are both provided with connecting structures. The connecting structures include steel plates 8 on both sides of the horizontal main rib in the width direction and nuts 9 provided on the outside of the steel plates 8 and threadedly connected to the ends of the internal corner anchor ring and the external corner anchor ring. Figure 3 As shown, both the internal corner anchor ring 12 and the external corner anchor ring are φ25 precision rolled threaded steel anchor rings, while the hook head tie rod 7 is a φ15 precision rolled threaded steel hook head tie rod. The anchor ring passes through the template 2, nut 9, steel plate 8 (with a φ30 hole at the centroid of the 100×100×10mm steel plate), double channel steel 4, steel plate 8, and nut 9 in sequence. The nut and steel plate clamp the double channel steel to prevent the anchor ring from slipping under force. During installation, first tighten the nut of the φ25 precision rolled threaded steel anchor ring at the internal corner, then hook the φ25 precision rolled threaded steel anchor ring at the internal and external corners with the φ15 precision rolled threaded steel hook head tie rod, and then tighten the nut of the φ25 precision rolled threaded steel anchor ring at the external corner. φ20 holes are opened 100mm from the end of the two double channel steels in two directions at the external corner, and φ25 precision rolled threaded steel and matching nuts are used for connection and locking.

[0026] In this embodiment, the external corner anchor rings and internal corner anchor rings arranged in the same direction are located on the same horizontal plane. By placing the external corner anchor rings and internal corner anchor rings arranged in the same direction on the same horizontal plane, the formed diagonal tie structure only acts in the horizontal direction, avoiding the generation of other decomposed forces in the vertical direction, which would affect the connection strength of the diagonal tie structure.

[0027] In this embodiment, the tie rod of the diagonal bracing structure located at the outermost corner of the support reinforcement device is interlocked with the tie rod in the tie structure by 300mm. In order to avoid the diagonal bracing structure at the corner from interfering with the tie structure of the conventional formwork support system, it is necessary to interlock the tie rod of the diagonal bracing structure located at the outermost corner of the corner with the tie rod in the tie structure by 300mm.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
