Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building construction, and in particular to a template clamping device for increasing the cross-section of a concrete member. Background Art
[0002] With the booming development of the construction industry, the reinforcement of concrete components has become increasingly important. In these projects, concrete components such as beams and columns often need to face various load-bearing and compressive tests to ensure the stability and safety of the structure. Among the many reinforcement methods for concrete components such as beams and columns, the cross-section reinforcement method has become a common method in reinforcement projects due to its mature technology, simple operation, and reliable load-bearing.
[0003] In the prior art, the reinforcement process of increasing the cross-section of concrete components is mainly completed by using prefabricated formwork and top frame. First, according to the reinforcement needs and design requirements, a prefabricated formwork, such as a C-shaped formwork, is set on the side to be reinforced of the beam and column, and then the formwork is firmly supported by the top frame. After the formwork is firmly supported, concrete is poured to increase the cross-section of the component. During the pouring process, the pouring speed and thickness of the concrete are strictly controlled so that the concrete can evenly and fully fill the inside of the formwork. After the pouring is completed and the concrete solidifies to a certain strength, the formwork can be removed.
[0004] Regarding the above-mentioned related technologies, since the construction process of the top frame support is cumbersome and complicated, it is necessary to accurately calculate and locate the support points. In addition, due to the instability of the top frame support, the formwork is prone to shift or deformation during the pouring process, resulting in uneven cross-section of the poured concrete components or even defects, affecting the pouring quality of the formwork. Utility Model Content
[0005] In order to improve the casting quality of the formwork, the present application provides a formwork clamping device for increasing the cross-section of a concrete member.
[0006] The present application provides a template clamping device for increasing the cross-section of a concrete member using the following technical solution:
[0007] A template clamping device for increasing the cross-section of a concrete member, comprising a clamping mechanism, wherein the clamping mechanism comprises a clamping and hanging assembly and a top mold assembly;
[0008] The clamping and hanging assembly comprises a clamping and hanging member, a support beam and two side beams;
[0009] The two side beams are fixedly connected to the two ends of the support beam, and the two side beams are symmetrically distributed about the support beam. The side beams are arranged perpendicular to the length direction of the support beam, and a clamping cavity for clamping the casting template is formed between the two side beams and the support beam;
[0010] The clamping and hanging parts are used for clamping and hanging the casting formwork;
[0011] The top mold assembly is used to fix the casting template.
[0012] By adopting the above technical scheme, first, the support beam and two side beams of the clamping assembly are fixedly installed at the position of the concrete component to be cast, so that the clamping cavity between the side beams is aligned with the casting template, and then the casting template is clamped and lifted by the clamping parts until the casting template completely enters the clamping cavity and is stably clamped. The casting template is further fixed by the top mold assembly, and concrete is poured after the template is fixed. After the pouring is completed and the concrete solidifies and reaches the expected strength, the top mold assembly is removed and the clamping parts are adjusted to separate the cast concrete component from the template, and then the entire clamping device is removed; the template clamping device for increasing the cross-section of the concrete component is convenient for dual fixation through the clamping assembly and the top mold assembly, ensuring the stability of the casting template during the casting process, reducing the displacement or deformation of the template during the casting process, and thus improving the casting quality of the template.
[0013] Preferably, one end of the side beam away from the casting formwork is fixedly connected to a reinforcement beam, and the reinforcement beam is arranged parallel to the length direction of the support beam.
[0014] By adopting the above technical solution, during the concrete pouring process, due to the weight of the concrete and the pouring pressure, the formwork and the clamping device will be subjected to large lateral forces and torsional forces. The set reinforcement beam can effectively resist these forces, prevent the formwork from shifting or the clamping device from deforming, ensure the smooth pouring process, and thus improve the pouring quality of the formwork; at the same time, the reinforcement beam is also beneficial to enhance the overall strength of the clamping device, so that it can withstand greater loads, which is particularly suitable for pouring large concrete components or using high-grade concrete.
[0015] Preferably, the clamping member includes two clamping bolts, the two clamping bolts are arranged opposite to each other, the clamping bolts pass through the side beam and are fixedly connected to the casting formwork, and the clamping bolts are threadedly connected to the side beam.
[0016] By adopting the above technical scheme, the two clamping bolts are arranged opposite to each other to ensure that the casting formwork is evenly stressed during the clamping process, and is not prone to displacement or tilting, which is beneficial to improving the clamping stability and ensuring the position accuracy of the formwork during the casting process; the threaded connection between the clamping bolts and the side beams makes the installation and adjustment process simple and quick, and the construction personnel can adjust the screw-in depth of the bolts according to actual needs to adapt to casting formworks of different thicknesses and sizes; the fixing method of the clamping bolts makes it easy to ensure the stability of the formwork during the lifting and casting process, reduce the risk of formwork displacement or falling off, and improve construction safety.
[0017] Preferably, the cross-sectional area of the ends of the two clamping bolts that are close to each other gradually decreases from the side away from the casting template to the side close to the casting template.
[0018] By adopting the above technical scheme, as the cross-sectional area of the clamping bolt gradually decreases, the clamping force of the clamping bolt will be more concentrated at the end close to the casting formwork, ensuring that the formwork is subjected to uniform and concentrated pressure when subjected to force, rather than dispersed or uneven force, which is beneficial to improving the stability and reliability of clamping; since the cross-sectional area of the clamping bolt gradually decreases, during the process of clamping the formwork, the tip of the bolt will not directly cause excessive pressure on the formwork, thereby avoiding local damage or deformation of the formwork; in addition, since the cross-sectional area of the bolt gradually decreases, the smaller cross-sectional part of the bolt can play a role when the formwork is thinner; when the formwork is thicker, the larger cross-sectional part of the bolt can ensure sufficient clamping force, which is beneficial to improving the versatility and flexibility of the clamping device.
[0019] Preferably, the clamping member further comprises two clamping nuts threadedly connected to each of the clamping bolts, and the two clamping nuts are respectively arranged on both sides of the side beam.
[0020] By adopting the above technical scheme, two clamping nuts are respectively arranged on both sides of the side beam and are tightly fixed together through the threaded connection of the clamping bolts, which is beneficial to enhancing the clamping force of the clamping parts on the casting formwork. The double clamping setting can ensure the stability and safety of the formwork during the casting process; the clamping nuts are respectively located on both sides of the side beam, which can evenly distribute the clamping force on both sides of the formwork, avoiding damage or deformation of the formwork due to excessive local pressure, thereby improving the casting quality of the formwork.
[0021] Preferably, the top form assembly includes two clamping bolts, the clamping bolts are arranged below the clamping bolts and the two clamping bolts are arranged opposite to each other, the clamping bolts pass through the side beams and abut against the casting formwork, and the clamping bolts are threadedly connected to the side beams.
[0022] By adopting the above technical scheme, two clamping bolts arranged opposite to each other can provide additional support and fixation on both sides of the casting formwork, thereby ensuring the stability of the formwork during the casting process, preventing the formwork from being displaced or deformed during the casting process, and ensuring the casting quality; the clamping bolts are arranged opposite to each other and pass through the side beams to abut against the formwork, which can form a uniform pressure distribution on the top of the formwork, avoid damage or deformation caused by excessive local force on the formwork, and increase the service life of the formwork; in addition, since the clamping bolts are threadedly connected to the side beams, construction personnel can easily adjust the screw-in depth of the clamping bolts to adapt to casting formworks of different thicknesses and sizes, thereby improving the versatility and adaptability of the top formwork assembly.
[0023] Preferably, at least two groups of the top mold assemblies are provided, and at least two groups of the top mold assemblies are evenly distributed along the length direction of the side beam.
[0024] By adopting the above technical solution, the uniform distribution of the top formwork components along the length direction of the side beam is conducive to improving the overall stability of the casting formwork, preventing the formwork from being deformed or displaced due to lateral pressure during the casting process, and ensuring the molding quality of the concrete components. At the same time, the uniform distribution of multiple groups of top formwork components enables the pressure on the formwork to be more evenly distributed on the entire formwork, which helps to reduce the situation where the formwork is subjected to excessive local force, reduce the risk of formwork damage and extend the service life of the formwork;
[0025] Preferably, the clamping mechanisms are provided in multiple groups, and the multiple groups of the clamping mechanisms are evenly distributed along the length direction of the casting template.
[0026] By adopting the above technical solution, multiple groups of clamping mechanisms are evenly distributed in the length direction of the casting formwork, which can provide comprehensive support and fixation for the formwork, significantly enhance the stability of the formwork during the casting process, prevent the formwork from displacement, deformation or tilting during the casting process, ensure the molding quality of the concrete components, reduce the situation where the formwork is subjected to excessive local force, reduce the risk of formwork damage and extend the service life of the formwork; in addition, by adjusting the spacing and position between the clamping mechanisms, it can flexibly adapt to casting formworks of different sizes and shapes.
[0027] In summary, the present application includes at least one of the following beneficial technical effects:
[0028] 1. The template clamping device for increasing the cross-section of concrete components is convenient for dual fixation through the clamping assembly and the top template assembly, ensuring the stability of the casting template during the casting process, reducing the displacement or deformation of the template during the casting process, and thus improving the casting quality of the template.
[0029] 2.
