[0002] Steel formwork is a special building formwork made of steel material. It is mainly used for the formwork support structure during concrete pouring. Steel formwork is widely used in construction due to its high strength, high rigidity, durability and high construction efficiency. It is especially common in large-scale projects. Steel formwork can replace traditional wooden formwork, plywood formwork, etc., and significantly reduce the pore water pressure and air bubbles in the concrete pressure caused by traditional sealing formworks such as wood and plywood, so that an ideal rough interface is formed after the structural concrete is poured.

[0003] The existing Chinese patent with announcement number CN207538451U discloses a steel formwork, including an outer mold and an inner mold, the outer mold and the inner mold are connected by tension bolts to form a mold cavity, the outer mold includes four side panels and encloses a rectangular space, and the adjacent side panels are fixedly connected by diagonal rods; the inner mold includes two bending portions with openings facing the center of the inner mold and two oppositely arranged straight sides, the bending portions and the straight sides together enclose a straight groove shape; the bending portion is composed of two corner molds fixedly connected to each other, the connection between the corner mold and the straight side is a demoulding adjustment portion and is fixed by bolts, and the adjustment portion is inclined.

[0004] Although the above scheme can demould quickly and conveniently, the process of splicing the steel formwork is relatively cumbersome, which affects the work efficiency. The installation and splicing are not convenient, which affects the use. Therefore, it does not meet the existing needs. In this regard, we propose a steel formwork that is easy to splice.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model opens a transmission cavity on one side of the interior of the steel template body. When docking, the first clamping block is moved into the interior of the first clamping groove. At this time, the knob is turned, and the knob drives the second rotating shaft to rotate synchronously. The rotation of the threaded rod causes the moving block to drive the limit block to be clamped into the first through hole, so that the first clamping block can be limited. Then, through the splicing of the first clamping block and the first clamping groove, and the limiting block and the first through hole, the splicing between the two steel template bodies is realized. It only needs to turn the knob, which is easy to use.

[0017] 2. The utility model opens a pulling cavity on the front and rear sides of one side of the inner side of the steel formwork body. When the pulling block is pulled before the two steel formwork bodies are spliced, the pulling block will drive the limiting rod to move synchronously, so that the second clamping block is inserted into the second clamping groove. When the pulling block is released, the sliding block will drive the limiting rod to move into the second through hole under the elastic action of the reset spring. Therefore, the splicing of the two steel formwork bodies is realized through the splicing of the second clamping block and the second clamping groove, and the limiting of the limiting rod and the second through hole, thereby ensuring the strength of the splicing. The splicing can be realized by pulling the pulling block.

[0018] 3. The utility model has stop rubber strips adhered and fixed on the upper and lower ends of one side of the steel formwork body, and rubber strip grooves are opened on the upper and lower ends of the other side of the steel formwork body.

[0028] When in use, pull the pull block 18 before the second clamping block 20 is inserted into the second clamping groove 19, so that the limit rod 16 can move synchronously to avoid affecting the insertion of the second clamping block 20. After the second clamping block 20 is inserted, release the pull block 18, and the elastic action of the reset spring 17 can make the limit rod 16 inserted into the second through hole 21, thereby completing the fixation of the second clamping block 20. Then, by turning the knob 12, the limit block 6 can be inserted into the inside of the first through hole 8, so that the first clamping block 7 is fixed in the inside of the first clamping groove 13, so that the splicing can be completed simply and conveniently, which is convenient for daily splicing operations.

[0029] See also Figure 4 A second rotating shaft 11 is arranged at the middle position inside the transmission chamber 2, one end of the second rotating shaft 11 penetrates and extends to the outside of the transmission chamber 2, and the second rotating shaft 11 is rotatably connected with the transmission chamber 2, one end of the threaded rod 3 is welded with the first rotating shaft 9, one end of the first rotating shaft 9 and the outer wall of one end of the second rotating shaft 11 located inside the transmission chamber 2 are both provided with a bevel gear 10, and the bevel gears 10 are meshedly connected, and the meshing connection of the bevel gears 10 realizes the synchronous rotation of the threaded rod 3 and the second rotating shaft 11;

By using the stop-grouting rubber strip 22 and the rubber strip groove 23 in coordination, the sealing of the joint of the steel formwork body 1 is increased, and the casting quality is improved;

[0034] See also Figure 1 , Figure 2 and Figure 3A knob 12 is provided at the upper end of the second rotating shaft 11, and a pull block 18 is welded to one end of the limit rod 16 located outside the pulling cavity 14. The setting of the knob 12 makes it convenient for the user to rotate the second rotating shaft 11, and the setting of the pull block 18 makes it convenient for the user to pull the limit rod 16.

[0035] Working principle: when in use, the two steel template bodies 1 are spliced ​​in the left and right directions, and the pulling block 18 is pulled toward the front and rear sides. The pulling block 18 will drive the limiting rod 16 to move synchronously and compress the reset spring 17. At this time, the second clamping block 20 is inserted into the second clamping groove 19. The pulling block 18 is released, and the slider 15 can be driven to slide inside the pulling cavity 14 under the elastic action of the reset spring 17. The slider 15 will drive one end of the limiting rod 16 to be inserted into the second through hole 21, so that the second clamping block 20 can be limited by the limiting block 6 to prevent the second clamping block 20 from falling out. When the second clamping block 20 is inserted into the second clamping groove 19, the first clamping block 7 will synchronously enter the first clamping groove 13. At this time, the knob 12 is turned, and the knob 12 will drive the second rotating shaft 11 to rotate, and the second rotating shaft 11 will drive one of the bevel gears 10 to rotate. Under the meshing transmission, the remaining two bevel gears 10 can make the first rotating shaft 9 rotate synchronously, the first rotating shaft 9 will drive the threaded rod 3 to rotate, and the threaded rod 3 will drive the moving block 5 to rotate synchronously. Since the yolk segment of the moving block 5 slides with the guide rod 4, the moving block 5 will be axially limited, and the rotation of the moving block 5 will be converted into horizontal linear movement, so that the moving block 5 can drive the limit block 6 to be stuck in the interior of the first through hole 8, and the first clamping block 7 is limited, so that the splicing of the two steel formwork bodies 1 can be completed. The whole process of splicing only requires pulling the pull block 18 and turning the knob 12, so that the splicing operation is simple and easy to operate. After the two steel formwork bodies 1 are spliced, the stop slurry strip 22 will be stuck in the interior of the strip groove 23. Through the coordinated use of the stop slurry strip 22 and the strip groove 23, the sealing of the splicing of the steel formwork body 1 is increased, and the casting quality is improved.
