Technical Field

[0001] The utility model relates to the field of construction, in particular to a template reinforcement structure for large-volume and heavy-weight special-shaped concrete components. Background Art

[0002] A large sports stadium features a ring beam, a critical load-bearing structure that connects the entire building. Its planar projection takes the shape of a ring belt, and its cross-section forms a parallelogram with curved sides. According to the design plan, the ring beam was divided into several sections for simultaneous construction. Each section was 10 meters long, with cross-sectional dimensions of 6.3 x 4.3 meters, and a total weight of approximately 730 tons per end. This presented a challenge: how to address the irregular, large, and heavy concrete structure. Without a reliable formwork and support system, problems such as mold slippage and expansion would inevitably occur during construction. Furthermore, without a contoured formwork system, significant material waste would be inevitable. Summary of the Invention

[0003] The utility model aims to overcome the defects of the prior art, provide a formwork reinforcement structure for large-volume and heavy-weight special-shaped concrete components, and solve the problems that are difficult to solve with special-shaped large-section prestressed ring beam formwork.

[0004] In order to solve the above technical problems, the utility model is achieved as follows:

[0005] A formwork reinforcement structure for large-volume and heavy-weight special-shaped concrete components is characterized in that it comprises a tire frame platform, two side formworks arranged on the tire frame platform and support frames respectively connected to the formworks.

[0006] The template reinforcement structure for large-volume and heavy-weight special-shaped concrete components is characterized in that the templates on both sides are inner templates and outer templates, which are respectively arranged on the inner side and the outer side of the component.

[0007] The template reinforcement structure for large-volume, heavy-weight special-shaped concrete components is characterized in that the inner template adopts a ribbed steel template, the support frame connected to the inner template adopts a truss, and the inner template and the truss are fixed by bolts.

[0008] The template reinforcement structure for large-volume, heavy-weight special-shaped concrete components is characterized in that the outer template is a wooden template, and the support frame connected to the outer template is a truss.

[0009] The template reinforcement structure for large-volume, heavy-weight special-shaped concrete components is characterized in that the outer molds are arranged at intervals, wooden back ribs are arranged between the outer molds, the outer molds are fixed to the wooden back ribs, and the wooden back ribs are firmly tied to the truss wire.

[0010] The template reinforcement structure for large-volume and heavy-weight special-shaped concrete components is characterized in that a bottom template is arranged between the tire frame platform and the component.

[0011] The template reinforcement structure for large-volume, heavy-weight special-shaped concrete components is characterized in that the bottom template is fan-shaped and includes a steel plate, a main keel radially arranged on the steel plate, and a secondary keel circumferentially arranged on the steel plate.

[0012] The template reinforcement structure for large-volume, heavy-weight special-shaped concrete components is characterized in that the tire frame platform includes a main keel and secondary keels arranged at intervals along the direction of the main keel, and the main keel and the secondary keel are connected by welding steel plates.

[0013] The template reinforcement structure for large-volume, heavy-weight special-shaped concrete components is characterized by further comprising top tensioning steel bars which are arranged at the top of the component to connect the inner template and the outer template.

[0014] The beneficial effects of the present invention are as follows: It can be seen from the above technical solutions that the present application provides a formwork reinforcement structure for large-volume, large-weight special-shaped concrete components, which is a formwork and support system that bears heavy loads and is particularly suitable for large-volume, large-weight concrete pouring operations. Since the outer side of the ring beam is regular in shape, a wooden formwork is used, and the inner side of the ring beam is a special-shaped arc surface, it is difficult to meet the requirements with ordinary wooden formwork. Therefore, the present formwork system customizes the steel formwork according to the structural shape, which solves the problem of the special-shaped formwork required for the special-shaped surface of the inner ring beam and fits the shape of the ring beam. The total weight of a single 10-meter section of the ring beam is 730 tons, which requires sufficient strength support. Therefore, the bottom formwork of the present invention adopts a steel plate combined with an I-beam keel; the side formwork adopts a ribbed steel formwork, and is reinforced with truss supports to ensure that the formwork has sufficient strength and does not deform. At the same time, it also ensures the quality of concrete pouring and molding. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will clearly and completely describe the technical solutions of the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection requested by this application.

[0025] like Figure 1 As shown: A formwork reinforcement structure for large-volume, large-weight special-shaped concrete components. In this embodiment, the large-volume, large-weight special-shaped concrete components are ring beams; a post-cast strip is set. According to the design, there are 12 sections of ring beam post-cast strips, each with a width of 3000; due to the large cross-sectional size of the ring beam and the dense internal steel bars, it is difficult to support the formwork. Considering the large cross-sectional size of the ring beam and the large number of longitudinal steel bars, it is difficult to temporarily seal the post-cast strip formwork; it is proposed to use wire mesh as a formwork in the outer main reinforcement area with the main bars running through the beam and the middle longitudinal steel bars. The main bars can pass directly through the wire mesh, and the internal area uses steel formwork. Straight threaded sleeves are connected to the ends of the internal steel bars. The post-cast strip steel bars are integrally connected to the large ring beam steel bars through straight threaded sleeves. At the same time, the end sealing plate of the post-tape is carried out by diagonal bracing or bracing.

[0026] Take one section of the ring beam as an example:

[0027] It comprises a tire frame platform 1, templates on both sides of the tire frame platform and support frames respectively connected with the templates.

[0028] The two side templates are an inner template 2 and an outer template 3, which are respectively arranged on the inner side and the outer side of the component.

[0029] like Figure 4 、 7 As shown: the inner form 2 adopts a ribbed steel formwork, the support frame connected to the inner form adopts a truss 4, and the inner form and the truss are fixed by bolts.

[0030] like Figure 5 、 8 As shown: the outer formwork 3 adopts a steel structure frame wooden formwork, and the supporting frame connected to the outer formwork adopts a truss 4.

[0031] The outer molds are arranged at intervals, and wooden back ribs are arranged between the outer molds. The outer molds are fixed to the annular arc-shaped wooden back ribs 5, and the wooden back ribs are firmly tied to the truss wires.

[0032] In the above formwork system, the outer formwork is configured with 4 construction section fixed steel frame wooden formworks in the same time period; the outer wooden formwork steel frame and the curved wooden back ribs are fixed with 10# iron wire; the main ribs of the inner steel formwork are welded to the panel and cross ribs, and the welded short-circuit 20# channel steel is connected to the supporting truss with M20 bolts.

[0033] In the above formwork system, the inner steel formwork support truss and steel formwork are put into use at the same time, and the configuration of the truss is combined with the layout of the steel formwork expansion area; the outer formwork support truss is configured with 4 construction section wooden formwork support trusses for rotation.

[0034] A bottom mold 6 is provided between the tire frame platform and the component.

[0035] like Figure 3 As shown: the bottom mold is fan-shaped, using 6mm steel plate + radial main keel 100*50*3 square steel pipe (spacing 200) + circumferential secondary keel 6# channel steel.

[0036] like Figure 2 、 6 As shown: the tire frame platform 1 includes a main keel 11 and secondary keels 12 arranged at intervals along the direction of the main keel. The main keel and the secondary keel are welded together by steel plates 13 to prevent slipping and tipping. A bottom template platform 14 is welded on the upper part of the secondary keel, and a diagonal brace 15 can also be added on one side of the secondary keel.

[0037] like Figure 1 As shown: it also includes top tension steel bars 7, which are arranged at the top of the component to connect the inner form and the outer form.

[0038] This formwork system customizes steel formwork based on the structural shape, eliminating the need for custom-shaped formwork for the irregularly shaped inner ring beam surface. The ring beam weighs 730 tons per 10-meter section, requiring sufficient strength. Therefore, the base formwork of this invention utilizes steel plates combined with I-beam keels. The side forms utilize ribbed steel formwork, reinforced with truss supports, ensuring sufficient strength and preventing deformation. This also ensures the quality of the concrete pour.

[0039] The above are only embodiments provided for this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
