Description

Technical Field

[0001] The utility model belongs to the technical field of water-stable steel formwork, and in particular relates to a water-stable steel formwork with high stability. Background Art

[0002] Water-stable steel formwork is a formwork system used for concrete construction. It is mainly used for the construction of water-stable layers (i.e. cement-stabilized gravel layers) in road construction projects, including the construction of water-stable layers in roads, squares, parking lots, etc. Compared with traditional wooden formwork, water-stable steel formwork has the advantages of light weight, long service life, low cost and high construction efficiency.

[0003] A water-stable base construction template is disclosed in a Chinese utility model patent with announcement number CN217419239U. The device includes a channel steel, a steel chisel and a connector connecting the channel steel and the steel chisel, wherein the upper end of the channel steel is provided with a snap-fitting piece that can be correspondingly engaged with the channel steel, and the first docking portion on the snap-fitting piece and the second docking portion on the connector can be connected by mortise and tenon joints, so that installation and disassembly are convenient and construction efficiency is high.

[0004] However, although the device is easy to install in actual use, due to the fact that gaps are inevitably present at the joints of two sets of adjacent steel templates when they are spliced, leakage is prone to occur at the joints of the steel templates.

[0005] In summary, there is a need for a water-stable steel formwork that can prevent gaps from appearing during the splicing process. Utility Model Content

[0006] The utility model aims to provide a high-stability water-stable steel formwork. By aligning the strip-shaped limiting protrusion with the strip-shaped limiting groove and fully inserting the insertion rod into the socket, the two sets of steel formworks can be quickly spliced ​​together, and the position of the strip-shaped limiting protrusion will be staggered with the position of the strip-shaped limiting groove as it rotates, thereby preventing the two sets of steel formworks from loosening and forming gaps, and ensuring the tightness of the connection between the two sets of steel formworks.

[0007] The technical solution adopted by the utility model to solve the above problems is: a high-stability water-stable steel formwork, comprising:

[0008] A first steel template body, a second steel template body is disposed on one side of the first steel template body, the first steel template body and the second steel template body are both provided with a socket, a plug rod is inserted into the socket, and an upper support frame and a lower support frame are fixedly connected to the plug rod respectively;

[0009] A strip-shaped limiting protrusion is fixedly connected to the outside of the insertion rod, and the inner side surface of the socket is provided with a strip-shaped limiting groove for installing the strip-shaped limiting protrusion.

[0010] Among them, the first steel formwork body and the second steel formwork body are the main parts of the formwork system, which are usually made of high-strength steel to ensure that they have sufficient rigidity and durability. The socket is a hollow cylinder arranged on the first steel formwork body and the second steel formwork body for inserting the plug rod. The main function of the socket is to fix the plug rod, connect the two steel formwork bodies, and provide additional support. The plug rod is inserted into the socket and is usually made of high-strength material to ensure that it can withstand the forces generated during the construction process. The plug rod is inserted into the socket of the first steel formwork body and the second steel formwork body to firmly connect the two formwork bodies together. At the same time, the upper support frame and the lower support frame are also fixed on the plug rod to provide additional support and stability.

[0011] A further preferred technical solution is that both the first steel template body and the second steel template body are provided with grooves for installing the socket.

[0012] The groove makes the first steel template body and the second steel template body present an overall "U" shape, so that multiple sockets can be easily installed inside to insert the plug rods.

[0013] A further preferred technical solution is that the length of the insertion rod is greater than the length between the closest points of the two groups of sockets on the first steel template body and the second steel template body.

[0014] Among them, the longer length of the plug rod means that it can pass through at least two sockets to form a connection point. This connection method increases the firmness of the template connection and the overall stability of the system.

[0015] A further preferred technical solution is that the cross-sectional diameter of the insertion rod is smaller than the inner diameter of the socket.

[0016] A further preferred technical solution is that: one insertion rod is provided at the top and one at the bottom, the upper support frame is provided on the upper insertion rod, and the lower support frame is provided on the lower insertion rod.

[0017] A further preferred technical solution is that: a positioning hole penetrating the upper support frame is provided on the upper support frame, and a positioning rod is inserted into the interior of the positioning hole.

[0018] A further preferred technical solution is that: a positioning hole penetrating the lower support frame is provided on the lower support frame, and a positioning rod is inserted into the positioning hole.

[0019] A further preferred technical solution is that the ends of the upper support frame and the lower support frame are both hingedly connected to a grounding plate via hinges.

[0020] A further preferred technical solution is that: the grounding plate is provided with a mounting hole penetrating the grounding plate.

[0021] Among them, the grounding plate provides a solid bottom support, transfers the force of the formwork system to the ground, reduces the shaking and instability of the formwork system caused by the upper load, and by fixing the grounding plate, it can ensure that the entire formwork system will not be displaced when subjected to force, thereby improving the overall stability. In addition, the design of the hinge connection allows the upper and lower support frames to be flexibly adjusted within a certain range, but the fixation of the grounding plate ensures the accuracy of the final positioning.

[0022] A further preferred technical solution is that the cross-sectional width of the strip-shaped limiting protrusion is smaller than the groove width of the strip-shaped limiting groove.

[0023] In summary, the utility model has the following benefits:

[0024] 1. The utility model can realize rapid splicing between two sets of steel templates by aligning the strip-shaped limiting protrusion with the strip-shaped limiting groove and completely inserting the insertion rod into the socket.

[0025] 2. After the strip limiting protrusion of the utility model moves out of the strip limiting groove, the upper support frame or the lower support frame is rotated to make the ground plate contact the ground, so that the insertion rod can also be driven to rotate together. At this time, the position of the strip limiting protrusion will be offset from the position of the strip limiting groove as the rotation occurs, so that the strip limiting protrusion will form a limit with the edge of the socket, thereby preventing the two sets of steel formworks from loosening and forming gaps, thereby ensuring the tightness of the connection between the two sets of steel formworks.

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0032] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0033] Example:

[0034] Please combine Figure 1-4 A high-stability water-stable steel formwork of this embodiment includes:

[0035] A first steel formwork body 1, a second steel formwork body 2 is arranged on one side of the first steel formwork body 1, the upper and lower parts of both sides of the first steel formwork body 1 and the second steel formwork body 2 are fixedly connected with sockets 3, the insides of two adjacent groups of sockets 3 on the same horizontal line are inserted with the same insertion rod 4, one end of the two groups of insertion rods 4 is respectively fixedly connected with an upper support frame 5 and a lower support frame 6, the first steel formwork body 1 and the second steel formwork body 2 are both U-shaped structures, the specifications of the first steel formwork body 1 and the second steel formwork body 2 are consistent, and it is convenient The steel templates are smoothly spliced, and the diameter of the plug rod 4 is consistent with the inner diameter of the socket 3, so that the plug rod 4 can be smoothly inserted into the socket 3. The inclination angle of the upper support frame 5 is greater than the inclination angle of the lower support frame 6, which is convenient for supporting the device. The surfaces of the upper support frame 5 and the lower support frame 6 are evenly spaced with positioning holes that penetrate the upper support frame 5 and the lower support frame 6. The inside of the positioning hole is inserted with a positioning rod 9, which can position the upper support frame 5 and the lower support frame 6 to prevent them from automatically rotating and causing the plug rod 4 to be separated from the socket 3;

[0036] The strip-shaped limiting protrusion 7 is symmetrically fixedly connected to the outside of the insertion rod 4, and the inner side surface of the socket 3 is symmetrically provided with a strip-shaped limiting groove 8. The length of the insertion rod 4 is greater than the sum of the lengths of two adjacent groups of sockets 3 on the same horizontal line, so that the strip-shaped limiting protrusion 7 can be smoothly moved out of the strip-shaped limiting groove 8 after the insertion rod 4 is fully inserted into the socket 3, and the shape and size of the strip-shaped limiting protrusion 7 are adapted to the strip-shaped limiting groove 8.

[0037] The implementation principle of a high-stability water-stable steel formwork in the embodiment of the present application is as follows: first, the first steel formwork body 1 and the second steel formwork body 2 are pieced together, and then the insertion rods 4 on the upper support frame 5 and the lower support frame 6 are respectively inserted into the adjacent sockets 3 at the upper and lower parts. During the insertion process, the strip limiting protrusions 7 and the strip limiting grooves 8 are aligned. When the insertion rod 4 is fully inserted, the upper support frame 5 and the lower support frame 6 are deflected respectively to drive the insertion rod 4 to deflect together. At this time, the position of the strip limiting protrusion 7 will be offset from the position of the strip limiting groove 8 as the rotation occurs, so that the strip limiting protrusion 7 will form a limit with the edge of the socket 3, thereby preventing the two groups of steel formworks from loosening and forming gaps, thereby ensuring the tightness of the connection between the two groups of steel formworks, and finally inserting the positioning rod 9 into the positioning hole and nailing it into the ground to position the upper support frame 5 and the lower support frame 6.

[0038] In addition, a further improvement is that the ends of the upper support frame 5 and the lower support frame 6 are hinged to the grounding plate 10 through hinges, and the surface of the grounding plate 10 is equidistantly provided with mounting holes 11 that penetrate the grounding plate 10. The grounding plate 10 is fixed to the ground through the mounting holes 11, so that the positioning effect of the upper support frame 5 and the lower support frame 6 can be further improved.

[0039] In addition, the same or similar element symbols are used to refer to the same or similar parts or steps in the drawings and descriptions as much as possible. The drawings are presented in simplified form and are not drawn to exact scale.
