Description

Technical Field

[0001] The utility model belongs to the technical field of beam bottom formwork supporting structures, and specifically discloses an adjustable supporting system of a formwork supporting frame that prevents eccentric force. Background Art

[0002] Compared with the traditional fastener support system, the socket-type disc-type formwork support system is widely used for its excellent stability, safety and long service life. However, in the structural design, the beams are not arranged completely according to the modulus of the disc-type scaffolding, which may lead to eccentric stress at the bottom of the beam in actual application.

[0003] Eccentric force will cause uneven force on each part of the support frame, thereby increasing the risk of structural instability. This will not only affect the support accuracy of the formwork, but also cause large deviations in the size and shape of the components after concrete pouring, thus affecting the overall construction quality. In the worst case, severe eccentric force may even cause the complete collapse of the support frame, posing a huge threat to personnel and equipment on the construction site.

[0004] Although managers are aware of the serious consequences of eccentric stress, the current adjustable support system cannot adapt to the situation where one or two steel pipes are supported at the bottom of the beam. In view of this, in addition to strengthening the supervision and inspection of the construction site to promptly discover and correct problems such as eccentric stress, it is also necessary to develop a new adjustable support system for the formwork support frame to fundamentally prevent the problem of eccentric stress and simplify the operation process of construction personnel.

[0031] When arranging one steel pipe in the utility model, the bolt is rotated upward through one of the opening bolt holes 1.1, so that the left rotating bar 6 rotates counterclockwise around the left fixed shaft 4, and the right rotating bar 7 rotates clockwise around the right fixed shaft 5, expanding the left rotating bar 6 and the right rotating bar 7, so that the expanded size is slightly larger than the size of a single steel pipe; the steel pipe is inserted from one end, and the bolt is screwed out, so that the right-side constraint groove 6.3 part of the left rotating bar 6 and the left-side constraint groove 7.3 part of the right rotating bar 7 clamp the steel pipe under the action of the tension spring 8, thus completing the fixation of a single steel pipe.

[0032] When arranging two steel pipes in this utility model, one steel pipe is placed between the left fixing strip restraint groove 2.1 and the left restraint groove 6.1 of the left rotating strip, and the other steel pipe is placed between the right fixing strip restraint groove 3.1 and the right restraint groove 7.1 of the right rotating strip.

[0033] In this utility model, the left fixing strip 2 and the right fixing strip 3 are used to firmly embed the two end steel pipes, ensuring the stability of the overall structure; the left fixed shaft 4 and the right fixed shaft 5 are symmetrically arranged on the left and right sides of the spreading bolt hole 1.1, allowing the left rotating strip 6 to freely rotate around the left fixed shaft 4 and the right rotating strip 7 to freely rotate around the right fixed shaft 5, so as to adapt to and fix steel pipes of different specifications; the spreading bolt hole 1.1 is located at the center of the bottom plate 1, facilitating the firm fixation of the two side steel pipes by passing bolts through the spreading bolt hole 1.1 when arranging two steel pipes, and at the same time enabling the left rotating strip 6 and the right rotating strip 7 to rotate to the required angles around the left fixed shaft 4 and the right fixed shaft 5 respectively, achieving precise positioning and adjustment.

[0034] In this utility model, the setting of the tension spring 8 enables the upper right end of the left rotating strip 6 and the upper left end of the right rotating strip 7 to naturally lean against each other in the non-use state, maintaining a compact structure. The left fixing strip 2 and the left rotating strip 6 cooperate to jointly embed one steel pipe, and the right fixing strip 3 and the right rotating strip 7 cooperate to jointly embed the other steel pipe, ensuring the overall stability. The left rotating strip 6 is hinged to the left fixed shaft 4, and the right rotating strip 7 is hinged to the right fixed shaft 5, enabling the left rotating strip 6 to rotate a certain angle around the left fixed shaft 4 and the right rotating strip 7 to rotate a certain angle around the right fixed shaft 5 to adapt to steel pipes of different specifications. The left restraint groove 6.3 on the right side of the left rotating strip 6 and the right restraint groove 7.3 on the left side of the right rotating strip 7 are specifically designed for the arrangement of a single steel pipe, which can effectively embed the steel pipe and prevent it from sliding or shifting during use.
