Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a supporting device for a concrete pouring formwork. Background Art

[0002] Building formwork is a temporary support structure, which is made according to the design requirements to shape the concrete structure and components according to the specified position and geometric size, maintain its correct position, and bear the self-weight of the building formwork and the external load acting on it. The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up the construction progress and reduce the cost of the project; during the use of building formwork, it is often necessary to use a support frame to fix it to the outside of the building where the concrete is poured. The support and formwork can be removed only after the concrete solidifies.

[0003] However, in the prior art, the concrete pouring formwork is often supported by an ordinary support rod that is diagonally supported on the ground. However, since only the top of the support rod is in contact with the formwork, its contact surface is very small, which will cause stress concentration on the formwork, thereby easily causing fatigue cracks or even fracture of the formwork. In addition, this method also has the problem of poor anti-slip performance and easy dumping of the formwork. Summary of the invention

[0004] In view of the defects existing in the prior art, the purpose of the present invention is to provide a support device for a concrete casting formwork, which can increase the contact area between the support device and the formwork and enhance the stability of the formwork.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] See also Figure 1 As shown, an embodiment of the present invention provides a support device for a concrete casting formwork, including an L-shaped support plate 1, a base 2 and a fixing device 3. The longer end of the L-shaped support plate 1 is tightly attached to the side of the formwork 6, thereby increasing the contact surface between the support device and the formwork 6, avoiding stress concentration on the formwork 6, and reducing the risk of fatigue cracks. The L-shaped support plate 1 is located above the base 2, and is hinged to the base 2 at its corner. The base 2 is provided with a mounting hole, and the anchor bolts pass through the mounting hole to fix the base 2 to the ground, thereby enhancing the stability of the support device. The fixing device 3 includes a support block 31 and a push-pull assembly 32. The push-pull assembly 32 includes a fixed portion 321 and a movable portion 322. The fixed portion 321 is fixed to the base 2, and the movable portion 322 is fixed to the base 2. The movable portion 322 passes through the fixed portion 321 and is fixedly connected to one side of the support block 31, and can move in a direction away from or close to the shorter end of the L-shaped support plate 1. The other side of the support block 31 is abutted against the shorter end of the L-shaped support plate. The support block 31 can move forward and backward on the base 2 under the action of the movable portion 322, thereby driving the L-shaped support plate 1 to move forward and backward, so that the longer end of the L-shaped support plate 1 tightly supports the template 6 to fix the template 6, thereby improving the stability of the template 6 and solving the problem of the template 6 being easy to tip over. When removing the template 6 and the supporting device, it is only necessary to unscrew the anchor bolts on the base 2, and remove the base 2 and the template 6. The disassembly and assembly and transportation are more convenient and quick, and are suitable for various types of building templates close to the ground.

[0025] Preferably, the supporting device also includes a connecting device 5, and the corner of the L-shaped supporting plate 1 is hinged on the base 2 through the connecting device 5; the connecting device 5 is composed of a hinge 51 and a connecting rod 52, one end of the connecting rod 52 is connected to the corner of the L-shaped supporting plate 1, and the other end is movably connected to the hinge 51; the hinge 51 is installed on the base 2 by screws, and when the supporting block 31 is pushed, the L-shaped supporting plate 1 will be driven to rotate around the hinge 51, and the positional relationship between the L-shaped supporting plate 1 and the template 6 can be quickly and conveniently adjusted, so that the longer end of the L-shaped supporting plate 1 is tightly attached to the side of the template 6, further enhancing the stability of the template 6.

[0026] Preferably, the support block 31 can be set as a right-angled triangular prism, and the inclined surface of the right-angled triangular prism is attached to the end of the shorter end of the L-shaped support plate 1. The inclined surface of the right-angled triangular prism forms an acute angle with the ground, which is conducive to the end of the L-shaped support plate 1 moving back and forth on the inclined surface, so that the L-shaped support plate 1 can rotate more flexibly around the hinge 51.

[0027] Preferably, Figure 2 As shown, the fixed part 321 of the push-pull assembly 32 includes a column 321A and a threaded tube 321B. The threaded tube 321B is preferably in the shape of a circular tube. One end of the column 321A is welded to the base 2, and the other end is welded to the bottom of the threaded tube 321B; the movable part 322 is preferably a threaded rod, and the support block 31 is moved by screwing the threaded rod in and out, thereby driving the L-shaped support plate 1 to rotate around the hinge 51, which is not only conducive to the rapid fixation of the L-shaped support plate 1, but also improves the stability of the support block 31; the length of the threaded rod is greater than the distance between the column 321A and the shorter end of the L-shaped support plate 1, ensuring that the threaded rod can push the support block 31 to fit the L-shaped support plate 1; in addition, a handle 323 can also be welded at the end of the threaded rod, and the handle 323 is preferably spherical, which is more convenient for construction personnel to control the threaded rod to move.

[0028] Among them, the L-shaped support plate 1, the base 2, the support block 31, the hinge 51, the column 321A, the threaded tube 321B, the threaded rod, the handle 323 and the connecting rod 52 are all made of stainless steel, which is strong, durable and has good corrosion resistance.

[0029] Preferably, a wear-increasing sleeve 4 is provided on the longer end of the L-shaped support plate 1. The wear-increasing sleeve 4 is made of rubber material with good elasticity and high friction coefficient, and is connected to the L-shaped support plate 1 by an adhesive, which is beneficial to increase the friction between the L-shaped support plate 1 and the template 6 and improve the anti-slip performance of the support device.

[0030] Method of using the supporting device: install the base 2 at a suitable position on the construction site, and align the wear-increasing sleeve 4 on the L-shaped supporting plate 1 with the template 6; then fix the base 2 to the ground with anchor bolts, or fix the base 2 by placing heavy objects; then hold the handle 323 and rotate the threaded rod to push the support block 31 toward the shorter end of the L-shaped supporting plate 1, so that the side of the support block 31 presses against the shorter end of the L-shaped supporting plate 1, and the L-shaped supporting plate 1 and the connecting rod 52 rotate around the hinge 51, thereby forcing the L-shaped supporting plate 1 to press tightly against the template 6, and the template 6 can be fixed; rotate the handle 323 in the opposite direction, withdraw the threaded rod and drive the support block 31 to separate from the L-shaped supporting plate 1, so that the L-shaped supporting plate 1 leaves the template 6, remove the base 2, and then the template 6 can be removed.

[0031] The present invention is not limited to the above-mentioned embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
