[0018] The utility model will be further described below in combination with the drawings and examples, but not as the basis for limiting the utility model.

[0019] The embodiment of the utility model discloses a low-consumption fast-assembly shear wall formwork structure, and each side of the formwork structure comprises staggered large formworks 1 and small formworks 2, a plurality of vertical secondary keels 3 are arranged at the outer sides of the large formworks 1 and the small formworks 2 at intervals, a plurality of horizontal main keels 4 are arranged at the outer sides of the vertical secondary keels 3, a plurality of pull-rod penetrating holes 7 are uniformly and intervally arranged on the small formworks 2 along the length direction, the pull-rod penetrating holes 7 are arranged on the two small formworks 2 arranged symmetrically, the pull-rod penetrating holes 7 are penetrated by the pull-rod 5, and the vertical secondary keel 3 and the horizontal main keel 4 can be tightly fixed on the surfaces of the large formwork 1 and the small formwork 2 through the locking and fixing members on the pull-rod 5.

[0020] The large formwork 1 and the small formwork 2 are arranged in an upper-lower staggered mode, and the lowest end and the highest end of the whole formwork structure are provided with the small formwork 2, as shown in the drawings. Figure 2 As shown in the drawings, two large formworks 1 are arranged in the height direction, the small formwork 2 is arranged between the two large formworks 1, the top of the upper large formwork 1 is also provided with the small formwork 2, the bottom of the lower large formwork 1 is also provided with the small formwork 2, the pull-rod 5 is penetrated into the small formwork 2, and the vertical secondary keel 3 is tightly fixed at the top and the bottom through the locking and fixing members on the pull-rod 5, so that the whole formwork structure is better fixed.

[0021] Each small formwork 2 is correspondingly provided with a group of horizontal main keels 4, and each group of horizontal main keels 4 is composed of two horizontal main keels 4 arranged on the upper and lower sides of the pull-rod 5.

[0022] The small formwork 2 and the adjacent large formwork 1 are fixedly connected together through the formwork strip 6, the formwork strip 6 is arranged in a staggered mode with the vertical secondary keel 3, in the early formwork installation process, the small formwork 2 and the large formwork 1 are temporarily fixed together through the formwork strip 6, and the formwork strip 6 facilitates the installation of the keel.

[0023] The principle of the low-consumption fast-assembly shear wall formwork structure of the utility model is based on the ingenious combination of the prefabricated small formwork 2 and the large formwork 1 and the main-keel and secondary-keel reinforcing system. The prefabricated small formwork 2 can be made of waste formworks, the pull-rod penetrating hole 7 is arranged at a designed distance, the small formwork 2 can be accurately spliced according to different shear wall sizes and shapes, and special positions can be filled. The large formwork 1 is used for large-area covering, does not need to be holed, and can avoid loss and structural weakening. The combination of the two can improve the utilization rate of the formwork and ensure the overall construction quality of the shear wall. In the main-keel and secondary-keel reinforcing system, the horizontal main keel 4 is arranged along the length direction of the shear wall as a main load-bearing component, bears the load and is transmitted to the support system, the vertical secondary keel 3 is distributed perpendicularly to the horizontal main keel 4, disperses the load and enhances the integrity, the pull-rod 5 is tightly fastened with the main keel and the secondary keel through the small formwork 2, supports the two side formwork structures and connects them into a whole, resists the lateral pressure of the concrete, ensures the stability of the formwork, and realizes efficient construction and formwork turnover through the cooperative work of the components.

[0024] Because the size of all small templates 2 and the positions of bolt insertion holes 7 are consistent, a fixed module is formed, and the positions of the holes on both sides of the shear wall are consistent during installation, so that the holes do not need to be opened again during installation, the installation of the bolt 5 is very fast, and the large template 1 does not need to be opened, and only the template strip 6 needs to be temporarily fixed during installation, so that the large template 1 does not need to pass through the bolt 5 again, and the rapid installation of the template structure is realized.

[0025] During the demolition process, the large template 1 does not need to be punched, and the demolition speed is also very fast. The main and secondary keels are loosened, and the large template 1 can be removed.

[0026] The low-consumption fast-installed shear wall template structure of the utility model completely abandons the traditional large-area punching and reinforcing method, and innovatively uses a prefabricated small template 2 structure. This structure design not only has reliable performance, but also has a simple and fast demolition process, greatly simplifying the construction process. At the same time, the combination of small templates 2 significantly improves the integrity and stability of the template, effectively avoiding the problem of template deformation caused by uneven local stress. Through this structural optimization design, the utilization rate of the template has been significantly improved.

[0027] Compared with the traditional shear wall formwork structure, the low-consumption fast-installed shear wall template structure has many significant advantages. First, the large template 1 does not need to be opened, which fundamentally reduces the degree of template loss. According to practical data statistics, after using this structure, the loss rate of the template is reduced by 50% compared with the traditional method, thereby increasing the template turnover frequency from 6 times to more than 12 times, and greatly prolonging the service life of the template. Second, the large template 1 can be directly and quickly installed without the need for complex splicing and reinforcing process, greatly improving the construction speed. In actual application, the use of this structure can improve the construction efficiency of the shear wall by more than 30%, and truly realizes the purpose of fast installation.

[0028] In summary, the low-consumption fast-installed shear wall template structure provides a more efficient and environmentally friendly solution for modern shear wall construction with its unique innovation and significant advantages. This structure effectively reduces construction costs, improves construction quality and efficiency, and plays a positive role in promoting resource conservation and environmental protection in the construction industry, and is an important technology that meets the green construction concept.

[0029] The specific construction method is as follows:

[0030] (1) Template combination design and calculation

[0031] Before construction, detailed formwork combination design should be carried out according to the specific structural size of shear wall, load condition and construction requirements. For small formwork 2, its quantity, size and splicing method should be accurately calculated to ensure flexible adaptation to the construction requirements of shear walls with different shapes and sizes. At the same time, according to the factors such as concrete lateral pressure, formwork self-weight and construction load, the specifications and spacing of main and secondary keels and the diameter and spacing of tensioning screw rod 5 are calculated to ensure that the strength and stability of the formwork support system meet the construction requirements.

[0032] (2) Formwork preparation and processing

[0033] According to the formwork combination design scheme, prepare small formwork 2 with appropriate size. Preferably, use waste formwork for processing to reduce cost and resource consumption. During processing, use professional equipment and tools to ensure that the surface of small formwork 2 is flat and free of deformation. According to the predetermined position, use accurate hole opening tools to open tensioning bolt penetration holes 7 on small formwork 2, and the hole diameter and hole spacing strictly meet the design specifications. At the same time, prepare the whole formwork as large formwork 1, select qualified finished formwork, check whether the edges and corners are complete and the surface is flat, and ensure that the formwork quality meets the requirements.

[0034] (3) Formwork positioning and installation

[0035] According to the construction drawings, accurately position the formwork. First, perform the setting-out, and clearly mark the frame lines and center lines of the shear wall. Then, install small formwork 2 according to the predetermined position, temporarily fix it using formwork strips 6 or clamps, and use tools such as levels and plumb lines to ensure that the perpendicularity and levelness of small formwork 2 meet the specification requirements. Then install large formwork 1, which is tightly attached to small formwork 2, and also temporarily fixed using formwork strips 6 or clamps. During installation, carefully check whether the formwork splicing is flat and tight to prevent slurry leakage.

[0036] (4) Formwork reinforcement treatment

[0037] Tensioning screw rod 5 installation: After preliminary positioning and installation of the formwork, according to the design requirements, penetrate the tensioning screw rod 5 at the predetermined position of small formwork 2, ensuring that the tensioning screw rod 5 penetrates the hole position of small formwork 2 accurately. The hole spacing and number of tensioning bolt penetration holes 7 of tensioning screw rod 5 should be reasonably planned according to the size of the formwork and reinforcement requirements.

[0038] Main and secondary keel installation and fastening: pass the tension rod 5 through the vertical secondary keel 3 (vertical steel pipe) and the horizontal main keel 4 (horizontal steel pipe) in sequence. First, install the vertical secondary keel 3, make it tightly adhere to the formwork, and preliminarily fix it with the tension rod 5 through the connecting piece; then install the horizontal main keel 4, which is arranged perpendicularly to the vertical secondary keel 3, and firmly connect it with the tension rod 5 and the vertical secondary keel 3 through the connecting piece. Finally, tighten the nut on the tension rod 5 using a wrench or other tools, tighten the tension rod 5, and make the support systems on both sides of the formwork into a whole, effectively resisting the lateral pressure of the concrete. At the same time, auxiliary reinforcing facilities such as support rods and crossbars can be set according to the actual situation to further enhance the overall stability of the formwork system, and the reinforcing facilities are tightly connected with the formwork and the main and secondary keels using iron wire or clamps.

[0039] (5) Concrete pouring and vibrating

[0040] After the formwork is reinforced, concrete pouring construction is carried out. During pouring, the pouring speed is strictly controlled to avoid deformation of the formwork caused by concrete impact. The concrete is fully vibrated using a vibrating rod to ensure that the concrete is dense and uniform. At the same time, arrange a person to closely observe the deformation of the formwork, and take timely measures to adjust and reinforce if there is any abnormality to ensure the quality of concrete pouring.

[0041] (6) Formwork removal and maintenance

[0042] After the concrete reaches the demolding condition, the formwork removal work is carried out. First, loosen the nut of the tension rod 5, then pull out the vertical secondary keel 3 and the horizontal main keel 4 in sequence. Use a sledging stick to gently sled the formwork to separate it from the concrete. Carefully operate during the removal process to avoid damaging the concrete surface and the formwork. The removed formwork needs to be cleaned in time to remove the concrete residues and stains on the surface. Check and repair the formwork, and repair or replace it in time if it is damaged. The cleaned and maintained formwork is stored in a dry and ventilated place to avoid moisture and deformation for subsequent construction use.
