Product Introduction of Limit Device for Flatness of Insulation-Integrated Cast-In-Place Non-Dismantling Formwork
In the construction of insulation-integrated cast-in-place non-dismantling formwork, the flatness of the insulation board directly determines the wall construction quality and insulation effect. The traditional method of supporting insulation boards with concrete strips is prone to problems such as difficult binding, unstable support, fracture and falling off, which in turn leads to the deviation and formwork shrinkage of insulation boards during concrete pouring, affecting construction accuracy. To this end, we have developed this limit device specifically to solve the problem of controlling the flatness of insulation boards, helping to improve the construction efficiency and quality of the cast-in-place non-dismantling formwork process, and adapting to various civil and industrial insulation-integrated wall construction scenarios.
As a core supporting accessory for insulation-integrated cast-in-place non-dismantling formwork, this product adopts an integrated structural design, consisting of two parts: a limit chuck and a limit support rod.The two are connected through the center position, which work together to achieve precise limit, firm fixation and flatness control of the insulation board. The structure is simple and easy to install, without the need for complex construction tools, greatly reducing the operation difficulty for construction personnel.
The core structural advantages are prominent, completely solving industry pain points: the limit chuck is fixed on the inner side of the insulation board, which can effectively align the splicing parts of adjacent insulation boards, eliminate the phenomenon of insulation board displacement and deviation during concrete pouring, and ensure the splicing flatness from the source; one end of the limit support rod is designed as a spiral tip , which can be easily rotated into the insulation board to quickly fix the chuck, and at the same time strengthen the connection firmness between the chuck and the insulation board, completely solving the problem of easy falling off of the traditional support method; the other end of the support rod is equipped with a tail plate with a diameter of 40mm , which can be directly supported on the inner side of the wooden formwork, accurately controlling the distance between the insulation board and the cement baffle, further improving the flatness and stability of the insulation board installation, and avoiding deformation and displacement during pouring.
Flexible installation, suitable for various construction scenarios: during construction, only multiple sets of this limit device need to be installed to support the inner wooden formwork and the insulation board synchronously, and fix the position of the insulation board efficiently. The device needs to be connected and fixed with the steel bars of the cast-in-place non-dismantling formwork wall, and the installation specifications are clear: different groups of limit devices are arranged in sequence along the splicing extension direction of the inner wooden formwork, and the spacing is set with reference to the standard spacing of the bottom leveling device; each group is equipped with 5-6 limit devices, which are evenly arranged at vertical intervals in the same group to ensure uniform support force, avoid insulation board deformation caused by uneven local force, and ensure the overall construction effect.
Full coverage of multiple models, strong versatility: this product covers 13 specifications and models, specifically 100, 160, 180, 200, 210, 230, 250, 300, 350, 400, 500, 550, 600 (unit: mm). It can be flexibly selected according to the construction needs of insulation-integrated cast-in-place non-dismantling formwork of different thicknesses and specifications, and is widely applicable to various insulation-integrated wall constructions such as civil buildings, industrial plants, and prefabricated buildings, meeting diverse construction needs in one stop.
Choosing this limit device can effectively avoid various drawbacks of the traditional support method, realize precise control of the flatness of the insulation board, reduce the construction rework rate, improve construction efficiency, and at the same time ensure the construction quality and durability of the insulation-integrated cast-in-place non-dismantling formwork process. It is an essential supporting product in insulation-integrated construction.
