[0002] In a construction site, formwork construction is an important part, and the installation and positioning of formwork greatly affect the construction quality of a building.

[0003] Currently, in the ongoing projects, the formwork positioning generally adopts the method of welding positioning bars to control the position of the formwork and the thickness of the protective layer.

[0004] In the existing method of welding positioning bars during the construction process at the construction site, an electric welding machine is required, and the electric welding machine needs to use high-voltage current. If the operation is improper, safety accidents such as electric shock or fire will be caused, thus increasing the operation difficulty and safety risk; at the same time, the traditional formwork positioning device needs to use the method of electric welding reinforcement, but in actual operation, if the spot welding current is too small, the strength of the welding point will be insufficient, and problems such as cracking are likely to occur, while if the spot welding current is too large, the control of the welding point may be poor, and even potential safety hazards will be caused. Therefore, the spot welding method in the prior art has a low error tolerance rate, and once the thickness of the protective layer is not well controlled, it cannot be reworked.

[0005] To sum up, the current new type of solderless template positioning device still has the following defects during use:

[0006] (1) Using an electric welding machine for welding has the risk of fire due to ignition, increasing the operation difficulty and safety risk;

[0007] (2) The original spot welding method has a low error tolerance rate, and once the thickness of the protective layer is not well controlled, it cannot be reworked. Summary of the Utility Model

[0012] As an improved technical solution, a rubber sheet is installed inside the metal half ring, and the rubber sheet is located on the outer surface of the steel bar.

[0013] As an improved technical solution, both ends of the metal half ring are provided with eyelets, and a group of the eyelets are internally movably connected with a metal tie.

[0014] As an improved technical solution, a protective layer is provided on one side of the steel bar, concrete is provided inside the protective layer, and a template is provided on one side of the protective layer.

[0033] In addition, in the present utility model, descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0034] Referring to Figures 1-6 , which is the first embodiment of the present utility model, a new type of solderless template positioning device is provided. This new type of solderless template positioning device includes a steel bar 7. A metal half-ring 1 is provided on the outer surface of the steel bar 7. A nut 3 is installed on the outer surface of the metal half-ring 1. A bolt 2 is threadedly connected inside the nut 3. One end of the bolt 2 extends to the outside of the nut 3. By turning the bolt 2, it can slowly extend into the inside of the nut 3. As Figure 3 shown, a protective layer is provided on one side of the steel bar 7. Concrete 8 is poured inside the protective layer. A template 9 is provided on one side of the concrete 8. By turning the bolt 2 to make it enter the inside of the nut 3, the length of the screw rod extending out can be made equal to the thickness of the protective layer, which can facilitate pressing against the template 9. The length of the rubber sheet 4 is longer than that of the metal half-ring 1. The metal half-ring 1 is arc-shaped. One end of the rubber sheet 4 is flush with the metal half-ring 1 and is also arc-shaped. The other end is longer than the metal half-ring 1. It can be tied to fit the surface of the steel bar 7 through a metal tie 5.

[0035] A rubber sheet 4 is installed inside the metal half-ring 1, and the rubber sheet 4 is located on the outer surface of the steel bar 7.

[0036] Eyelets 6 are installed at both ends of the metal half-ring 1. A metal tie 5 is movably connected inside a set of eyelets 6. The other end of the metal half-ring 1 can pass through the inside of another set of eyelets 6. As Figure 4 shown, the diameter of one end of the metal tie 5 is larger than the diameter of the groove of the eyelet 6. Therefore, the metal tie 5 can be limited. Similarly, the other end of the metal tie 5 is in a pointed shape, which can facilitate passing through another set of eyelets 6. The metal tie 5 is a strip made of metal wire and has a certain elasticity and toughness. As Figure 4 shown, the eyelet 6 is a convex structure, and a groove structure is opened inside it for fixing the metal tie 5. Since the metal tie 5 is made of flexible and tough metal wire, a strong acting force can be generated by tightening, and thus the eyelet 6 can be firmly fixed.

[0037] A protective layer is provided on one side of the steel bar 7. Concrete 8 is provided inside the protective layer. A template 9 is provided on one side of the protective layer.

[0038] The bolt 2 is located inside the protective layer and on the inner side of the formwork 9, facilitating the positioning device to hold against it.

[0039] During use, as Figure 2 shown, slip the non-weld formwork positioning device over the outer surface of the steel bar 7, and pass the other end of the metal tie 5 through another set of eyelets 6. Then, tighten the metal tie 5 to fix the device on the outer surface of the steel bar 7.

[0040] Subsequently, the screw 2 can be adjusted according to the thickness of the protective layer. Twist the screw 2 so that it slowly enters the nut 3 by the acting force of the thread, making the length of the screw 2 consistent with the thickness of the protective layer.

[0041] As Figure 3 shown, install the formwork 9 to be positioned on the outside of the steel bar 7, hold it with the non-weld formwork positioning device, and pour the concrete 8. After the concrete 8 solidifies, remove the formwork 9 to complete the overall operation.

[0042] When using the traditional formwork positioning device with the electric welding reinforcement method, due to the influence of the number and quality of welding points, the error tolerance rate is low, that is, the formwork cannot be accurately installed in the specified position. When operating with the reinforcement method of the screw 2, the length of the screw 2 can be adjusted according to the thickness of the protective layer, which can ensure that the position and height of the formwork 9 are relatively stable during the installation process, thereby improving the reinforcement accuracy of the formwork and avoiding the problem of low error tolerance rate brought by the electric welding reinforcement method used in the traditional formwork positioning device.

[0043] Meanwhile, during construction, only the staff needs to carry a wrench, which solves the risk factor of using an electric welding machine for welding and the need for fire. The construction personnel do not need to carry an electric welding machine and are not affected by factors such as wire conditions, and this method is simple to operate.

[0044] In addition, if the construction times among various trades are not coordinated, or the steel bar workers do not cut and deliver the materials in advance, it will cause the assembly process of other trades to be blocked, thus reducing the construction efficiency. At the same time, if the steel bar workers fail to cut the materials in time, it will cause problems such as the formwork 9 being unable to be nailed or clamped tightly, thus affecting safety. This method does not require the steel bar workers to cut the materials in advance, solves the problem of coordination among various trades, and thus can solve the problem of low construction efficiency of multiple trades, making the construction more flexible and convenient, and further improving the work efficiency.

[0045] Finally, traditional template positioning devices need to use electric welding, which will generate a large amount of harmful gases and particles. These gases and particles will be discharged into the air along with the flue gas, seriously polluting the air quality. In addition, the strong light generated during electric welding operation will directly shine into people's eyes, causing vision damage, which is an obvious form of light pollution. This method uses raw material processing, has the characteristics of on-site finished product installation and high integration, and can reduce air pollution, light pollution, etc. caused by electric welding construction at the construction site;

[0046] In summary, this new type of template welding-free positioning device has the advantages of high integration, one-time construction in place, simple operation, no need for power supply and other condition restrictions, no pollution, etc., and can ensure the structural stress safety.

[0047] It should be understood that the use of these embodiments is only for illustrating the present invention and is not intended to limit the protection scope of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications and / or variations to the present invention, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
