Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of construction engineering, and in particular to a special-shaped component template reinforcement structure and a construction method. Background Art
[0002] Formwork is widely used in modern construction. Conventional formwork is used for conical pools like these, using conventional flat formwork splicing. However, during the concrete pouring process, certain enclosure reinforcements are required to prevent the cement slurry from flowing around. In the water treatment industry, conical pools with conical bottoms are often used to facilitate the collection and discharge of solid sediments. However, due to the special shape of the conical pool, the pressure generated by the cement's own weight is distributed downward, resulting in the need for additional support at the bottom of the cone.
[0003] When ordinary formwork bears the deadweight of cement, especially at the formwork joints, due to the lack of sufficient targeted reinforcement measures, when a large amount of cement accumulates in the wider area at the bottom of the cone, the pressure on the formwork here increases. The structural design of ordinary formwork is difficult to withstand such concentrated and large pressure, causing the formwork to gradually deform under the deadweight of cement and eventually burst. As a result, the pool will leak after construction, resulting in the need for frequent subsequent maintenance and upkeep. Summary of the Invention
[0004] In order to solve the above problems, the present invention proposes a special-shaped component template reinforcement structure and a construction method.
[0005] A reinforcement structure for a special-shaped component formwork comprises a bottom load-bearing structure, transverse reinforcement beams, and at least two upper load-bearing structures, wherein the bottom of the upper load-bearing structure is fixedly connected to the formwork shell; the bottom load-bearing structure provides foundation support for the entire reinforcement system, ensuring that the lower portion of the formwork is firm and resists sinking or displacement. In the background art, the pressure at the bottom of a conical water tank is concentrated, which can easily cause the formwork to deform. The bottom load-bearing structure anchors the oblique fixings through fixings, distributing the concrete's deadweight and lateral pressure to the foundation, preventing local stress concentration, reducing the risk of bursting at the lower portion of the formwork shell, and enhancing overall stability.
[0006] Furthermore, the upper bearing structure is located on top of the formwork, bearing part of the vertical pressure during concrete pouring. The top of the formwork shell is fixed by anchoring vertical fixings to prevent displacement or tilting.
[0007] Furthermore, the transverse reinforcement beam is a core reinforcement component in the horizontal direction, which resists the lateral pressure of concrete and prevents horizontal deformation or displacement of the formwork.
[0008] Furthermore, the formwork shell serves as the formwork in direct contact with the concrete, and its height and thickness are optimized for special-shaped components to ensure complete coverage of the pouring area and avoid incomplete pouring or gaps.
[0009] Furthermore, it also includes an oblique fixing member and a fixing member arranged inside the bottom load-bearing structure, the oblique fixing member is fixedly connected to the inner side of the template shell, the top end of the oblique fixing member is provided with a bent hook section, the oblique fixing member is anchored to the transverse reinforcement beam through the bent hook section, and the bottom end of the oblique fixing member is fixedly connected to the fixing member;
[0010] Furthermore, the diagonal fixings address the concentrated pressure at the lower part of the cone, with the curved hook section providing reliable anchoring. Spacing restrictions ensure uniform stress distribution and prevent localized deformation; they also distribute the concrete's deadweight pressure, preventing cracking at the lower part of the formwork; and the curved hook section ensures a secure anchoring to the transverse reinforcement beam, enhancing overturning resistance.
[0011] Furthermore, the fixings serve as the bottom anchor points for the diagonal fixings, transferring diagonal forces to the underlying load-bearing structure. In the background art, the pressure at the bottom of the formwork is greatest, and the fixings secure the diagonal fixings in place. This prevents the bottom of the fixings from slipping, ensuring effective force transfer to the foundation while dispersing the pressure from below, reducing the risk of deformation.
[0012] Furthermore, a vertical fixing piece is fixedly connected to the inner side of the template shell, the top of the vertical fixing piece is anchored to the upper bearing structure, and the bottom end of the vertical fixing piece is provided with a vertical bending section, which is anchored to the transverse reinforcement beam through the vertical bending section.
[0013] Furthermore, the vertical fixings primarily resist vertical pressure. Anchor points are added to the bottom of the vertical bend, creating a bidirectional fixation with the top anchor. This bidirectional anchoring resists vertical pressure, preventing the formwork from compressing or bending. Together with the diagonal fixings, it forms a support network, providing vertical load bearing and stability.
[0014] Furthermore, a vertical connecting fixture is provided inside the transverse reinforcement beam, and the template shell and the transverse reinforcement beam are fixedly connected by the vertical connecting fixture.
[0015] Furthermore, the two ends of the vertical connecting fixture pass through the formwork shell and the transverse reinforcement beam respectively. The part of the vertical connecting fixture extending out of the formwork shell is bent to form a second constraint end that is hooked on the outer surface of the formwork shell. The part of the vertical connecting fixture extending out of the transverse reinforcement beam is bent to form a first constraint end that is embedded in the inside of the transverse reinforcement beam.
[0016] Furthermore, the vertical connecting fixings directly connect the formwork shell and the transverse reinforcement beam, and the restraining end is bent to form a mechanical lock to prevent horizontal displacement, enhance the connection reliability, resist the horizontal thrust during pouring, ensure the integration of the formwork shell and the reinforcement beam, and reduce deformation at the splicing.
[0017] Furthermore, the oblique fixing piece and the vertical fixing piece are fixedly connected with a twisted steel wire 1, the surface of the twisted steel wire 1 is fixedly connected with an S-shaped fixed steel bar, and the connection between the oblique fixing piece and the vertical fixing piece is fixedly connected with a twisted steel wire 2.
[0018] Furthermore, the twisted steel wire provides winding force, and the S-shaped fixing steel bars prevent it from loosening. The winding design enhances the integrity of the vertical and diagonal fixings and prevents relative displacement; the S-shaped fixing steel bars provide additional constraints to ensure long-term stability.
[0019] Furthermore, the intersection of the fixings is a stress concentration area, and the twisted steel wire is used to reinforce the node to prevent cracking; the strength of the intersection is improved to reduce the risk of failure caused by stress concentration.
[0020] Furthermore, the winding pitch of the twisted steel wire is 2 to 3 times the diameter of the fixing member, and the bending radius of the S-shaped fixing steel bar is ≤ 5 times the diameter of the twisted steel wire.
[0021] Furthermore, the angle between the oblique fixing member and the horizontal plane is 55° to 65°, and the horizontal spacing between the bottom ends of adjacent oblique fixing members is ≤ 1.5 times the thickness of the template shell.
[0022] Furthermore, a cofferdam is provided inside the formwork shell, and the cross section of the cofferdam is L-shaped. The L-shaped design addresses the problem of concrete slurry fluidity and prevents the slurry from overflowing from the gaps in the formwork.
[0023] Furthermore, the height of the formwork shell is 5900-6000 mm, and the thickness is 290-310 mm; the thickness of the transverse reinforcement beam is 300-400 mm.
[0024] Furthermore, the bottom load-bearing structure mentioned in this application refers to a permanent building structure located below the special-shaped component or at the foundation, which provides vertical reaction support and horizontal constraint anchoring, and can transfer the load borne by the formwork to the foundation or main frame.
[0025] Furthermore, the upper bearing structure mentioned in this application refers to an existing building structure located on the top or upper side of the special-shaped component, providing a vertical hanging support and horizontal limit, which is used to anchor the vertical load-bearing components of the formwork and constrain their displacement.
[0026] Furthermore, the fixing member is made of a material that can bear a large load, such as a steel bar, a steel member, etc.
[0027] A construction method for a special-shaped component formwork reinforcement structure comprises the following steps:
[0028] 1. Construction preparation stage:
[0029] Clean and level the foundation to ensure that the bearing capacity meets the requirements; install the bottom load-bearing structure and preset fixings inside it to anchor the bottom end of the oblique fixings.
[0030] The position of the fixings must be accurately positioned to ensure the installation angle of the oblique fixings.
[0031] 2. Assemble the template shell and the fixing frame
[0032] Positioning the upper load-bearing structure and formwork shell: Hoist the upper load-bearing structure to the designed elevation and secure it with temporary supports. Install the formwork shell at the bottom of the structure, ensuring a height of 5900-6000mm and a thickness of 290-310mm.
[0033] Pre-weld an L-shaped cofferdam on the inside of the formwork shell to prevent the concrete slurry from overflowing.
[0034] Vertical Fixing Installation: Secure the vertical fixing to the upper center portion of the inner shell of the formwork. Anchor the top of the fixing to the interior of the upper support structure. Bend the bottom of the fixing vertically to form a vertical bend, leaving space for connection to the transverse reinforcement beam.
[0035] Installation of oblique fixings: Fix the oblique fixings in the lower middle part of the inner side of the template shell, insert the bottom end into the fixings of the bottom load-bearing structure and weld it in place.
[0036] Adjust the angle of the oblique fixings to 55°~65°, and ensure that the horizontal spacing between the bottom ends of adjacent fixings is ≤ 1.5 times the thickness of the formwork shell.
[0037] A bent hook section is prefabricated at the top of the oblique fixing piece for subsequent anchoring with the transverse reinforcement beam;
[0038] Installation of transverse reinforcement beams: The thickness of the hoisted transverse reinforcement beams is 300 to 400 mm and is located at the middle height of the formwork shell.
[0039] The vertical bent section of the vertical fixing piece is passed through the bottom of the transverse reinforcement beam and is welded and anchored.
[0040] Insert the bent hook section at the top of the oblique fixing piece into the transverse reinforcement beam and mechanically lock it.
[0041] Installation of vertical connection fixings: Install vertical connection fixings inside the transverse reinforcement beam.
[0042] Its two ends penetrate the upper middle portion of the formwork shell and the left and right sides of the transverse reinforcement beam respectively; the top end passes through the formwork shell via an inclined bent section and is bent to form a second restraining end, which is hooked onto the outer surface of the formwork shell. The bottom end passes through the transverse reinforcement beam via an inclined bent section and is bent to form a first restraining end, which is embedded in the beam.
[0043] Fixing with twisted steel wire and S-shaped fixings: Wrap twisted steel wire around the outside of vertical fixings and oblique fixings, and strictly control the pitch to 2 to 3 times the diameter of the fixings.
[0044] Tie S-shaped fixed steel bars on one surface of the twisted steel wire with a bending radius ≤ 5 times the diameter of the twisted steel wire to prevent loosening.
[0045] Tie twisted steel wire 2 at the intersection of the vertical fixings and the diagonal fixings to strengthen the integrity of the node.
[0046] Cofferdam sealing inspection: verify the tightness of the joint between the L-shaped cofferdam and the formwork shell, and inject sealant if necessary to prevent concrete slurry leakage.
[0047] 3. Concrete pouring and formwork removal;
[0048] 4. Layered pouring of concrete: adopt a layered pouring strategy, give priority to pouring the wide area at the bottom of the conical pool to avoid pressure concentration, control the pouring speed, use cofferdams to prevent slurry overflow, and ensure uniform force on the formwork.
[0049] Formwork removal and curing: After the concrete strength reaches 70% of the design value, remove the formwork in reverse order:
[0050] Remove the twisted steel wire and S-shaped fixing steel bars; remove the horizontal reinforcement beams and vertical connecting fixings; remove the diagonal fixings and vertical fixings; finally, dismantle the formwork shell and cofferdam.
[0051] After dismantling, water and maintain for 28 days, focusing on checking whether there are cracks and leakage at the joints of the template.
[0052] Compared with the existing technology, the present invention has the following beneficial effects: the vertical pressure generated during concrete pouring is dispersed and transmitted by the vertical fixings through the upper and lower anchor points, the upper bearing structure and the transverse reinforcement beams; the lateral pressure is decomposed into vertical and horizontal components by the oblique fixings with an inclination angle of 55° to 65°. The vertical component is introduced into the foundation through the bottom fixings, and the horizontal component is borne by the transverse reinforcement beams;
[0053] At the same time, the restraining end of the vertical connection fixing locks the horizontal displacement of the formwork shell and the reinforced beam, the twisted steel wire and S-shaped fixings strengthen the coordination of the fixing nodes, and the L-shaped cofferdam blocks the leakage of slurry, finally forming a spatial grid-like rigid system, which completely solves the deformation, bursting and leakage problems of the special-shaped component formwork.

The bottom of the upper load-bearing structure 2 is fixedly connected to the formwork shell 4; the bottom load-bearing structure 1 provides foundation support for the entire reinforcement system, ensuring that the lower part of the formwork is firm and resists sinking or displacement. In the background art, the pressure at the bottom of the conical water tank is concentrated, which can easily cause the formwork to deform. The bottom load-bearing structure 1 anchors the oblique fixings 6 through fixings 11, dispersing the concrete's own weight and lateral pressure to the foundation, preventing local stress concentration, reducing the risk of bursting at the lower part of the formwork shell 4, and enhancing overall stability.
[0078] The upper bearing structure 2 is located at the top of the formwork and bears part of the vertical pressure when pouring concrete. The top of the formwork shell 4 is fixed by anchoring the vertical fixing members 5 to prevent displacement or tilting.
[0079] The transverse reinforcement beam 3 is a core reinforcement component in the horizontal direction, which resists the lateral pressure of concrete and prevents the horizontal deformation or displacement of the formwork.
