Description

Technical Field

[0001] This utility model relates to the field of steel formwork technology, specifically to a steel formwork for building construction that can be quickly assembled. Background Technology

[0002] Steel formwork is a steel template used for concrete pouring and shaping. In addition to steel formwork, there are also wooden formwork, plywood formwork, etc. When installing existing steel formwork, the steel formwork is usually spliced ​​and glued together first, and then the two steel formworks are fixed together using steel bars and bolts. This fixing method requires the use of multiple bolts to lock the steel bars to the two steel formworks to achieve connection and fixation. As a result, the installation of steel formwork consumes a lot of workers' time, and when it is dismantled later, a large number of bolts need to be removed to remove the steel formwork. Therefore, we propose a quick-assembly steel formwork for building construction to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of this utility model provides a quick-assembly steel formwork for building construction, comprising two steel formwork bodies 1, which are tightly fitted together. Each steel formwork body 1 has a support frame 2 fixed inside. Two fixing holes 3 are provided on each side wall of the two support frames 2. A box body 4 is snapped onto each of the two steel formwork bodies 1. A bidirectional lead screw 5 is rotatably connected to the inside of the box body 4 via bearings. Both ends of the bidirectional lead screw 5 are threadedly connected to movable plates 6 that are adapted to the threads on their surfaces. Both ends of the two movable plates 6 are fixed with fixing plates 7 that are adapted to the fixing holes 3. One end of each fixing plate 7 slides through the box body 4 and extends to its exterior. It is inserted into the corresponding fixing hole 3. The surface of the box body 4 is provided with four clearance slots 14 to allow the fixing plate 7 to move. The clearance slots 14 can provide clearance so that the fixing plate 7 will not be interfered with when it slides through the box body 4 to the outside. At the same time, they can limit the fixing plate 7 so that when the bidirectional screw 5 rotates and drives the moving plate 6 to move, the moving plate 6 will not rotate synchronously with the bidirectional screw 5. The front of the box body 4 is rotatably connected to the drive shaft 8 through the bearing. The surface of the drive shaft 8 is slidably connected to the handwheel 11. The surface of the drive shaft 8 is fixed. A driving bevel gear 9 is fixed, and a driven bevel gear 10 is fixed to the surface of the double-acting screw 5. The driven bevel gear 10 meshes with the driving bevel gear 9. A locking assembly 12 is provided on the front of the housing 4 to prevent the drive shaft 8 from loosening after rotation. When using this quick-assembly steel formwork for construction, after splicing and fitting the two steel formwork bodies 1 together, the housing 4 can be snapped between the two steel formwork bodies 1. Then, the handwheel 11 can be pressed first. Because pressing the handwheel 11 will release the locking assembly 12, the handwheel 11 can then be operated to drive the drive shaft 8 to rotate. At this time, with the cooperation of the driving bevel gear 9 and the driven bevel gear 10, the drive shaft 8 rotates. After the drive shaft 8 rotates, it will drive the double-acting screw 5 to rotate. After the double-acting screw 5 rotates, it will drive the two moving plates 6 to move in opposite directions. After the moving plates 6 move, they can drive the fixed plates 7 on both sides to move respectively. After the fixed plates 7 move, they will be inserted into the fixed holes 3 of the support frames 2 on both sides respectively. Then, the two spliced ​​and fitted steel template bodies 1 can be connected and fixed. After the splicing is completed, the handwheel 11 is released. At this time, the locking component 12 can limit the handwheel 11, thereby preventing the drive shaft 8 from rotating loosely. When the steel template body 1 needs to be removed later, just press the handwheel 11 and rotate it in the opposite direction.

[0024] like Figure 2 and Figure 4As shown, in some embodiments, the locking assembly 12 includes an annular seat 1201 rotatably mounted on the front of the housing 4. Two springs 1202 are fixed to the front of the annular seat 1201, and two telescopic covers 1206 are fixed to the front of the annular seat 1201. The other ends of the telescopic covers 1206 are fixedly connected to the handwheel 11. The telescopic covers 1206 can protect the springs 1202, reducing the impact of the external environment and thus extending their service life. The other ends of the springs 1202 are fixedly connected to the handwheel 11. A mounting plate 1203 is fixed to the front of the housing 4, and a fixed toothed ring 1204 is fixed inside the through hole on the front of the mounting plate 1203. A movable gear ring 1205 is fixed on the front of the handwheel 11. The movable gear ring 1205 is engaged with the fixed gear ring 1204. When in use, when the operator presses the handwheel 11, the spring 1202 will be compressed, and the handwheel 11 will move the movable gear ring 1205 after being pressed. At this time, the movable gear ring 1205 will disengage from the fixed gear ring 1204, and then the operator can operate the handwheel 11 to drive the transmission shaft 8 to rotate in both directions. When the pressure on the handwheel 11 is released, the restoring force of the spring 1202 will drive the handwheel 11 to drive the movable gear ring 1205 to re-engage with the fixed gear ring 1204, thus locking the transmission shaft 8.

[0025] like Figure 4 As shown, in some embodiments, a telescopic rod 1207 is provided inside the spring 1202. One end of the telescopic rod 1207 is fixedly connected to the annular seat 1201, and the other end of the telescopic rod 1207 is fixedly connected to the handwheel 11. With the cooperation of the telescopic rod 1207, the annular seat 1201 can be rotated more easily when the handwheel 11 is pressed.

[0026] like Figure 1 As shown, in some embodiments, four guide plates 13 adapted to the box body 4 are fixed inside the steel template body 1. The box body 4 is limited and locked between the four guide plates 13. The guide plates 13 can play an auxiliary guiding and supporting role for the box body 4, so that the box body 4 will be more stable after being locked onto the two steel template bodies 1.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
