[0002] Building formwork is a temporary support structure, which is made according to the design requirements, so that the concrete structure and components are formed at the specified positions and geometric dimensions, keep their correct positions, and bear the self-weight of the building formwork and the external loads acting on it. The purpose of formwork engineering is to ensure the quality of concrete engineering, construction safety, speed up the construction progress and reduce the project cost. During the building construction process, the formwork needs to be fixed before the concrete pouring activity can be carried out.

[0003] The "fixing device for building formwork" disclosed in the application number "201921532279.2" thereof "comprises a first support rod, a first locking device is fixedly connected to the left side of the first support rod, the first support rod is connected to a second support rod through the first locking device, a second locking device is fixedly connected to the lower side of the second support rod, the second support rod is connected to a third support rod through the second locking device, a third locking device is fixedly connected to the right side of the third support rod, the third support rod is connected to a fourth support rod through the third locking device, a fourth locking device is fixedly connected to the upper side of the fourth support rod, and the fourth support rod is fixedly connected to the first support rod through the fourth locking device. The first locking device comprises a locking ring and a lower support plate. A fixing nut is arranged on the lower side of the locking ring, the fixing nut is threadedly connected with a fixing bolt, an upper support plate is fixedly connected to the upper side of the locking ring, a first threaded rod is arranged on the upper left side of the lower support plate, a second threaded rod is arranged on the upper right side of the lower support plate, a lower anti-slip strip is arranged in the middle of the upper side of the lower support plate, the second support rod is arranged on the upper side of the lower anti-slip strip, the upper support plate is sleeved with the first threaded rod and the second threaded rod on the upper side of the lower support plate, an upper anti-slip strip is fixedly connected to the lower side of the upper support plate, the upper side of the first threaded rod is threadedly connected with a first locking nut, and the upper side of the second threaded rod is threadedly connected with a second locking nut". In the utility model, the upper anti-slip strip and the lower anti-slip strip are made of silica gel. On the one hand, the upper anti-slip strip and the lower anti-slip strip have certain elasticity. On the other hand, the surface of the silica gel strip has certain roughness, which can increase the friction force at the contact part between the support rod and the upper and lower anti-slip strips, so that the support rod is not easy to slide left and right or up and down, and the firmness of the fixing device is increased. By setting the first locking nut and the second locking nut together to fix the support rod, the fixing effect is better. The locking ring adopts a clamp structure, which makes it more convenient to put the support rod in and take it out. At the same time, the disassembly process of the clamp structure is relatively simple. Generally speaking, the utility model increases the firmness of the fixing device, simplifies the operation steps and improves the work efficiency.
