When they are placed vertically or obliquely, they have a natural tendency to topple under the action of gravity. Secondly, during concrete pouring, concrete is in a fluid state, which will exert lateral pressure on the steel formwork. As the height of the concrete increases, the lateral pressure will also increase, which will interfere with the stability of the steel formwork, so it needs to be reinforced to prevent toppling to ensure construction safety and concrete forming quality.

[0004] But the existing part of anti-toppling fixing device is usually connected with steel formwork by bolt to form support in actual construction, this connection mode determines that its installation steps are extremely complicated.

The whole process not only consumes a lot of time, but also requires construction personnel to have high operation proficiency. Not only leads to the situation of low installation efficiency, seriously delays the whole construction progress. At the same time, due to the complicated installation process and long time, it is difficult to ensure that the fixing device is always in accurate and stable state during concrete pouring, which is easy to cause the problems of uneven surface and large size deviation of concrete during forming, greatly affects the forming effect of concrete, cannot meet the strict requirements of high-quality construction, therefore, in view of the above shortcomings, a steel formwork anti-toppling fixing device is proposed to solve the above problems.

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] REFERENCE Figures 1 to 3The utility model provides an embodiment: a kind of steel formwork anti-toppling fixing device, including two support shafts 1, support shaft 1 as the important support structure of whole device, its length design needs to be determined according to the size of steel formwork 8 and actual use demand, to ensure that it can stably provide rotating fulcrum for support mechanism. Two ends are fixed firmly in the outside of the inner cavity of steel formwork 8 by welding process. The outside of two support shafts 1 is rotatably connected with support mechanism, the inside of two support mechanisms is slidably connected with ground insertion mechanism, the outside of two support shafts 1 is fixedly connected with steel formwork 8, the bottom of steel formwork 8 is fixedly connected with multiple second thorn parts 11, and second thorn part 11 is used to insert into ground to further carry out preliminary positioning to steel formwork 8, the material of second thorn part 11 is same with steel formwork 8, its shape is sharp thorn structure, length is moderate, can be inserted into ground certain depth by the gravity or slight pressure of steel formwork 8 itself when device is placed on ground, to preliminarily position and stabilize steel formwork 8, reduce the shaking or displacement of steel formwork 8 before installing and fixing insertion rod 6.

[0024] Referring to Figures 2 to 4 The inside of steel formwork 8 is fixedly connected with limiting mechanism, two support mechanisms include cross bar 4, the top of two cross bars 4 is fixedly connected with inclined rod 3, and one end of inclined rod 3 is fixedly connected with the top of cross bar 4, forming stable triangular support structure, to enhance the stability of entire support mechanism. The rear side of two cross bars 4 is fixedly connected with first sleeve 2, and cross bar 4 can be synchronously and stably rotated when first sleeve 2 rotates on support shaft 1. When installing, first sleeve 2 is sleeved on support shaft 1, and the angle change of cross bar 4 and inclined rod 3 relative to support shaft 1 is realized by the rotating characteristics thereof, to meet the shape requirement of device under different use scenarios, whether cross bar 4 is perpendicular to steel formwork 8 when installing or is parallelly fitted with steel formwork 8 when storing. The rear side of two inclined rods 3 is fixedly connected with first sleeve 2, the inside of first sleeve 2 is slidably connected with the outside of support shaft 1, the outside of first sleeve 2 is rotatably connected with the inside of support shaft 1, and the front side of two cross bars 4 is fixedly connected with second sleeve 5.

[0025] Referring to Figures 2 to 3 Two ground insertion mechanisms include fixed insertion rod 6, and the outside of two fixed insertion rods 6 is slidably connected with the inside of two second sleeves 5 respectively, and the bottom of two fixed insertion rods 6 is fixedly connected with first thorn part 7. Fixed insertion rod 6 is inserted into ground through first thorn part 7, and first thorn part 7 is designed into sharp shape, which is conical, to be more easily inserted into ground. When using, first thorn part 7 is inserted into ground after being penetrated from the upper port to the lower port of second sleeve 5 by driving fixed insertion rod 6 to slide in second sleeve 5, to fix the entire device with ground, to prevent steel formwork 8 from toppling.

[0026] Referring to Figures 2 to 4The limiting mechanism comprises two limiting sleeves 9, the outer portion of the cross bar 4 is slidingly connected to the inner portion of the limiting sleeve 9, the limiting sleeve 9 provides a sliding track and a limiting space for the cross bar 4 when the device is stored, so that the cross bar 4 can smoothly slide into the inner portion of the limiting sleeve 9 after being rotated to the state of parallel and close-fitting with the steel formwork 8, and is appropriately constrained by the elastic member 10, thereby preventing the cross bar 4 from shaking or falling out at will.

The outer portion of the cross bar 4 is in contact with the outer portion of the elastic member 10. When the cross bar 4 is rotated and slides into the inner portion of the limiting sleeve 9 when the device is stored, the cross bar 4 will press the elastic member 10, and the elastic member 10 will be elastically deformed and store elastic potential energy. The elastic potential energy will generate a reverse force on the cross bar 4, so that the cross bar 4 can maintain a stable position in the limiting sleeve 9. Meanwhile, when it is needed to deploy the device for use, the cross bar 4 can be pulled out of the limiting sleeve 9 and rotated to the installation position by overcoming the elastic force of the elastic member 10.

When it is needed to store the fixing device, the fixed insertion rod 6 is taken out of the ground and the second sleeve 5, the cross bar 4 and the inclined rod 3 are rotated on the outer wall of the support shaft 1 through the upper and lower first sleeves 2, the cross bar 4, the second sleeve 5 and the inclined rod 3 are rotated to be parallel and close-fitting with the steel formwork 8, at this time, the cross bar 4 will press the elastic member 10 and finally slide into the inner portion of the limiting sleeve 9, thereby realizing the rapid storage of the anti-toppling fixing device, reducing the space occupation of the anti-toppling fixing device, and facilitating the storage and transportation thereof.
