Description

Technical Field

[0001] The present invention relates to the technical field of steel formwork, and in particular to a steel formwork that is easy to install. Background Art

[0002] Steel formwork, also known as non-disassembly formwork net, can replace wooden formwork, significantly reducing the pore water pressure and air bubble removal in the concrete pressure usually caused by traditional sealing formwork such as wood, plywood, or steel plates. After the concrete of the steel formwork structure is poured and formed, an ideal rough interface is formed. The existing steel formwork generally includes a plate surface and a back rib, which has good strength.

[0003] Existing steel formworks generally use bolts for splicing and installation. There are generally two ways to use bolts. One is to directly open a thread groove on the back rib and screw the bolt into the thread groove on the back rib for installation. This method requires tapping on the back rib, and the process cost is relatively high. Another method does not require tapping. Directly open a hole on the back rib, insert the bolt into the hole, and then screw on the nut from the other side. In this method, since the nut and bolt need to be completely separated, it takes a long time to screw the bolt in and out the nut. The operation is time-consuming and labor-intensive, which brings a lot of trouble to the installation of the steel formwork. Utility Model Content

[0004] In order to make up for the deficiencies of the existing technical problems, the purpose of the utility model is to provide an installation component that first presses a pressing rod and then rotates an installation knob to solve the problem that the installation of steel templates is time-consuming and labor-intensive.

[0005] In order to solve the problems of the existing technology, the technical solution of the utility model is as follows: a steel formwork that is easy to install, mainly composed of a steel panel and a steel back rib, and mounting holes are opened on the steel back rib. These mounting holes can be slidably connected to the mounting tube, and the outer wall of the mounting tube is provided with a threaded groove, which allows threaded connection through the installation knob. This design makes the fixation of the mounting tube both firm and flexible. The installation assembly is the key to achieving quick connection between the steel back rib and the mounting tube. This assembly is realized by the sliding connection between the pressing rod and the mounting tube. The pressing rod can pass through one side of the mounting tube, which is convenient for user operation.

[0006] Preferably, a spring is fixedly connected to one end of the pressing rod, and the other end of the spring is connected to the inner wall of the mounting tube. This design enables the pressing rod to automatically reset when no force is applied, which not only facilitates user operation but also ensures the stability and reliability of the mounting assembly.

[0007] Preferably, the driving block on the outer wall of the pressing rod forms a linkage mechanism with the rotating bolt. When the user presses the pressing rod, the driving block will move accordingly, thereby driving the rotating bolt to rotate. This design cleverly utilizes the principle of mechanical transmission and realizes the synchronous movement of multiple mounting plates through simple operation.

[0008] Preferably, the mounting plates are evenly distributed on the mounting cylinder, and each mounting plate is connected to the driving block by a rotating bolt. When the pressing rod is pressed, all the mounting plates will be retracted inward at the same time. When the pressing rod is released, the mounting plates will extend outward at the same time, closely contact and fix with the steel formwork. This design not only improves the installation efficiency, but also ensures the uniformity and stability of the connection.

[0009] Preferably, the limiting grooves provided on the outer wall of the mounting tube are used to limit the range of movement of the mounting plate to prevent it from accidentally sliding or falling off in a non-operating state. This design enhances the safety and reliability of the entire mounting assembly.

[0010] Compared with the prior art, the advantages of the present invention are as follows:

[0011] The utility model provides an installation component. By pressing the pressing rod, the installation plate slides forward along the inner wall of the limit groove, the installation cylinder is inserted along the inner walls of the two aligned installation holes, the pressing rod is released and the installation cylinder is pulled backward until the installation plate contacts the outer wall of the front steel back rib, and the installation knob is turned until it is in close contact with the outer wall of the rear steel back rib, thereby realizing rapid connection and fixation between the two steel templates, greatly shortening the installation time. Construction personnel can complete the template installation work more efficiently, speeding up the project progress and improving construction efficiency.

[0012] The utility model provides mounting holes and mounting knobs, and only straight grooves need to be opened without tapping, thereby reducing the process cost of the steel formwork. The mounting knob does not need to be separated from the mounting tube, and only the moving space of the mounting plate needs to be ensured, which simplifies the installation steps and reduces the labor intensity of construction workers. During the installation process, the various components cooperate closely to ensure the accuracy and stability of the formwork. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] See also Figure 1-3 A steel formwork that is easy to install is mainly composed of a steel panel 1 and a steel back rib 2. The steel panel 1 serves as the main bearing surface of the formwork and is in direct contact with the concrete to form the desired concrete structure shape. The material of the steel panel 1 ensures that it has high strength and durability and can withstand the pressure and impact during the concrete pouring process. The steel back rib 2 provides support and fixation for the steel panel 1. The design of the steel back rib 2 enables the formwork to maintain a stable shape and size during the pouring process, preventing the formwork from deformation or displacement. At the same time, the steel back rib 2 is also a fixed base for the installation component and provides an installation position for components such as the installation tube 4. The steel back rib 2 is provided with installation holes 3. The installation holes 3 are holes opened on the steel back rib 2 for installing the installation tube 4. The design of the installation holes 3 allows the installation tube 4 to be easily inserted and fixed on the steel back rib 2, providing a basis for subsequent quick connection. These installation holes 3 can be slidably connected to the installation tube 4. The installation tube 4 is fixed by cooperating with the threaded groove 5 and the installation knob 6. The installation tube 4 is not only a carrier for the installation component, but also achieves quick connection and fixation with the formwork body through its structural design. The outer wall of the tube 4 is provided with a threaded groove 5, which allows for threaded connection through the installation knob 6. This design makes the fixation of the installation tube 4 both firm and flexible. The installation component is the key to achieving quick connection between the steel back rib 2 and the installation tube 4. This component is achieved by the sliding connection between the pressing rod 7 and the installation tube 4. The pressing rod 7 can pass through one side of the installation tube 4, which is convenient for user operation. By setting up the installation component, pressing the pressing rod 7 drives the mounting plate 11 to slide forward along the inner wall of the limit groove 12, and the mounting tube 4 is inserted along the inner walls of the two aligned mounting holes 3. Release the pressing rod 7 and pull the mounting tube 4 backward until the mounting plate 11 contacts the outer wall of the front steel back rib 2, and rotate the installation knob 6 until it is in close contact with the outer wall of the rear steel back rib 2, thereby achieving rapid connection and fixation between the two steel formworks, greatly shortening the installation time, and construction personnel can complete the installation of the formwork more efficiently, speeding up the project progress, and improving construction efficiency.

[0019] See also Figure 2-3The installation assembly includes components such as a pressing rod 7, a spring 8, a driving block 9, a rotating bolt 10 and a mounting plate 11. The installation assembly realizes the rapid connection and fixation of the template body and the mounting cylinder 4 through a series of mechanical linkage actions. The operation of the pressing rod 7 causes the driving block 9 to move, thereby driving the rotating bolt 10 to rotate, driving the mounting plate 11 to extend outward and contact and fix the connecting piece. The pressing rod 7 is used as an operating rod to start the installation assembly by pressing. The spring 8 provides a reset force for the pressing rod 7 to ensure that the pressing rod 7 can automatically reset when it is not under force. The driving block 9 is connected to the pressing rod 7 to transmit the movement of the pressing rod 7 to the rotating bolt 10. The rotating bolt 10 drives the mounting plate 11 to extend or retract by rotation. The plate 11 contacts and is fixed with the connecting piece to realize the connection between the template body and the mounting tube 4. The limiting groove 12 is opened on the outer wall of the mounting tube 4 to limit the moving range of the mounting plate 11. The design of the limiting groove 12 prevents the mounting plate 11 from accidentally sliding or falling off in the non-operating state, thereby enhancing the safety and reliability of the installation assembly. By setting the mounting hole 3 and the mounting knob 6, only a straight groove needs to be opened without tapping, which reduces the process cost of the steel template, and the mounting knob 6 does not need to be separated from the mounting tube 4. It is only necessary to ensure the moving space of the mounting plate 11, which simplifies the installation steps and reduces the labor intensity of the construction personnel. The components cooperate closely during the installation process to ensure the accuracy and stability of the template.

[0020] When in use, the operator aligns the mounting holes 3 on the steel back ribs 2 of the two steel templates to be installed, presses the pressing rod 7, and the pressing rod 7 squeezes the spring 8 while driving the driving block 9 to move forward, and the driving block 9 drives the rotating bolt 10 to move, and the rotating bolt 10 drives the mounting plate 11 to slide forward along the inner wall of the limiting groove 12 until the mounting plate 11 is completely received in the mounting tube 4, and inserts the mounting tube 4 along the inner wall of the two aligned mounting holes 3 until the mounting plate 11 is completely located through the mounting hole 3 on the front steel back rib 2, releases the pressing rod 7, and due to the reciprocating nature of the spring 8, drives the pressing rod 7 to move forward. The rod 7 moves backward, and the pressing rod 7 drives the driving block 9 to move backward. The driving block 9 drives the mounting plate 11 to move backward by rotating the bolt 10. The mounting plate 11 passes through the limiting groove 12 and moves out of the mounting tube 4. The mounting tube 4 is pulled backward until the mounting plate 11 contacts the outer wall of the front steel back rib 2. The mounting knob 6 is rotated, and the mounting knob 6 moves forward along the outer wall of the threaded groove 5 threadedly connected to it until the mounting knob 6 is in close contact with the outer wall of the rear steel back rib 2. Repeat the above operation on multiple mounting holes 3 on the steel back rib 2 of the two steel templates, and the two steel templates can be tightly installed and connected.
