Detailed Description

The invention will be further elucidated and described with reference to the drawings and embodiments. The utility model discloses in the technical characteristics of each embodiment under the prerequisite that does not conflict each other, all can carry out corresponding combination.

As shown in fig. 1, in order to provide a detachable adjustable rigid supporting frame according to a preferred embodiment of the present invention, the main structure of the detachable adjustable rigid supporting frame is divided into three sections, which are a first connecting section 1, a second connecting section 2 and a third connecting section 3 in sequence. The top of first linkage segment 1 is equipped with top articulated joint 8 for with treat the steel construction that supports and carry out interim fixing. The bottom of first linkage segment 1 and the 2 tops of second linkage segment are equipped with a ring flange 4 respectively, all offer the screw of one-to-one on two ring flanges 4, and both are just fixed temporarily to accessible twist screw bolt and nut after the laminating, can dismantle again when needing the adjustment. The bottom of the second connecting section 2 is of a hollow structure, the bottom of the second connecting section needs to be internally tapped, an adjusting screw rod 6 is fixed at the top of the third connecting section 3, the upper portion of the adjusting screw rod 6 extends into the second connecting section 2 and forms thread fit with the bottom of the second connecting section 2, the second connecting section 2 is rotated to throughput the adjusting screw rod 6, the length of the adjusting screw rod 6 between the second connecting section 2 and the third connecting section 3 is changed, and then the length of the rigid support frame is adjusted according to construction needs. For the convenience of rotation, a rotation handle 5 is fixed on the second connecting section 2. The two rotating handles 5 in this embodiment are symmetrically arranged at the same height of the second connecting section 2. The bottom of the third connecting section 3 is provided with a bottom hinged joint 7, and the bottom hinged joint 7 is hinged with a fixed base 9. The bottom of the fixed base 9 is planar and is provided with a screw hole for fixing the fixed base to the ground.

During actual construction, the rotating handle 5 can be formed by bending a phi 10 steel bar commonly used in a construction site and then welding the bent bar onto the second connecting section 2. The first connecting section 1, the second connecting section 2 and the third connecting section 3 can also all adopt common circular steel tubes, and the diameter of the steel tube can be adjusted according to the actual requirements of engineering. Because the tapping is comparatively troublesome in the steel pipe bottom, consequently can carry out convergent processing to 2 bottoms of second linkage segments and 3 tops of third linkage segments, then weld a nut respectively, constitute screw-thread fit through nut and adjusting screw 6.

When the rigid support frame is used, an inclined angle is required to be formed for supporting, as shown in fig. 2. And the steel column is used as a steel structure to be supported, and the use method of the rigid support frame is displayed through two application scene cases.

In the application process, as shown in fig. 3, the bottom of the steel column 10 is fixed on the foundation through bolts, and a connecting piece 11 with a circular hole is installed at a certain height on the side of the steel column 10. The fixed base 9 at the bottom of the rigid support frame is fixed on the foundation through bolts. When the length of the rigid support frame needs to be adjusted, the bolts and the nuts on the two flange plates 4 can be unscrewed, then the exposed length of the adjusting screw 6 is adjusted by rotating the rotating handle 5, when the length is adjusted to a proper position, the two flange plates 4 are connected again, and then the hinge joint 8 at the top of the rigid support frame is hinged with the connecting piece 11, so that the rigid support of the steel column 10 is realized. The supporting angle between the rigid supporting frame and the steel structure is preferably between 30 and 45 degrees, and the specific size can be adjusted according to the construction site conditions. Each steel column only needs one rigid support frame.

As shown in fig. 4, another application scenario is different in that the bottom of the steel column 10 can be fixed by inserting into the foundation pit 12 and then curing the concrete.

Of course, the support frame can be used as a temporary support frame for mounting other steel structures besides the steel columns. For other support frames, the utility model discloses with little of steel volume, rigidity is big.

The above-mentioned embodiments are merely a preferred embodiment of the present invention, but it is not intended to limit the present invention. Various changes and modifications can be made by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present invention. Therefore, all the technical schemes obtained by adopting the mode of equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
