Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering construction, and specifically relates to a single-leg steel support structure. Background Art

[0002] Construction joints in the basement are a common phenomenon during the concrete pouring process. They are joints generated because concrete pouring needs to be carried out in sections. The existence of such joints may affect the integrity of the concrete. When pouring concrete, if the construction joints are not properly treated, it may cause the concrete to segregate, that is, the coarse and fine aggregates of the concrete separate, affecting the quality of the concrete. The existence of construction joints may reduce the strength and durability of the concrete structure. Especially in the top-down construction method, the construction joints generated between the lower concrete constructed later and the upper concrete constructed earlier will have an adverse impact on the strength, durability and waterproofness of the structure. Therefore, supporting and treating the construction joints is a necessary measure to ensure the quality of concrete pouring and the structural integrity.

[0003] Most of the existing support structures use a large number of steel pipes and plates to support them. This support method has poor load-bearing capacity and unstable structure.

[0004] Therefore, the utility model provides a single-leg steel support structure to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a single-leg steel support structure, which solves the problems of poor load-bearing capacity and unstable structure, and has the technical effects of strong load-bearing capacity and stable structure.

[0006] A single-leg steel support structure includes a single-leg steel section. A wooden cushion block for preventing the single-leg steel section from being damaged is arranged below the single-leg steel section. A jacking structure for supporting the wooden cushion block and the single-leg steel section is arranged below the wooden cushion block.

[0007] The jacking structure includes a steel plate. A support vertical rod is vertically welded to the bottom of the steel plate. Two semi-circular rings are sleeved outside the support vertical rod. Safety rings are respectively arranged on the outer side surfaces of the two semi-circular rings.

[0008] Fixing plates are respectively arranged at both ends of the two semi-circular rings. Threaded holes are arranged on the surfaces of the fixing plates. The fixing plates on the two semi-circular rings are arranged oppositely. After the threaded holes on the fixing plates are aligned, they are fixed by bolts.

[0009] The thickness of the steel plate is 5 mm, the thickness of the semi-circular ring is 3 mm, and the length of the bolt is 10 mm.

[0019] In order to more clearly illustrate the technical features of the present solution, the present solution will be described below through specific embodiments.

[0020] Refer to Figure 1 - Figure 2 , a single-leg steel section support structure, including a single-leg steel section 1. A wooden cushion block 4 for preventing the single-leg steel section 1 from being damaged is arranged below the single-leg steel section 1. The wooden cushion block 4 is mainly used to enhance the strength and stiffness of the structure and bear the torque. Installing the wooden cushion block 4 can also prevent the single-leg steel section 1 from directly contacting the jack structure and being damaged. A jack structure for supporting the wooden cushion block 4 and the single-leg steel section 1 is arranged below the wooden cushion block 4.

[0021] The supporting structure includes a steel plate 2. A supporting vertical rod 6 is vertically welded to the bottom of the steel plate 2. Two semi-circular rings 3 are sleeved outside the supporting vertical rod 6. Safety rings 8 are respectively arranged on the outer side surfaces of the two semi-circular rings 3. The safety rings 8 can prevent the supporting structure from malfunctioning during use. Since the working environment of the supporting structure is harsh, the existence of the safety rings 8 can, to a certain extent, prevent these malfunctions from occurring, improve safety, and at the same time ensure the integrity and stability of the supporting structure.

[0022] Fixing plates 7 are respectively arranged at both ends of the two semi-circular rings 3. Threaded holes are arranged on the surfaces of the fixing plates 7. The fixing plates 7 on the two semi-circular rings 3 are arranged oppositely. After the threaded holes on the fixing plates 7 are aligned, they are fixed by bolts 5. The two semi-circular rings 3 form a lock, which can ensure that the supporting structure can be firmly locked in place, prevent loosening or displacement, and can play the effect of stable support.

[0023] The thickness of the steel plate 2 is 5 mm, the thickness of the semi-circular ring 3 is 3 mm, and the length of the bolt 5 is 10 mm.

[0024] The single-leg steel section 1 is arranged under the beams on both sides of the post-cast strip, at a position 400 mm away from the beam end. The supporting height of the single-leg steel section 1 is 3.78 m, and the supporting spacing of the single-leg steel section 1 is not greater than 5 m.

The supporting spacing of the single-leg steel section 1 is not greater than 5 m. Since the structure and material of the single-leg steel section 1 itself can provide sufficient supporting force, and the cutting seams of the single-leg steel section 1 are flat and the dimensions have no deviation, no formwork matching is required. Install the supporting structure under the beams on both sides of the post-cast strip (supporting whenever there is a beam) at a position 400 mm away from the beam end.

[0028] The supporting structure includes a steel plate 2. A supporting vertical rod 6 is welded to the bottom of the steel plate 2. Two semi-circular rings 3 are sleeved outside the supporting vertical rod 6. Safety rings 8 are respectively arranged on the outer side surfaces of the two semi-circular rings 3. The safety rings 8 can prevent the supporting structure from malfunctioning during use. Since the working environment of the supporting structure is harsh, the existence of the safety rings 8 can, to a certain extent, prevent these malfunctions from occurring, improve safety, and at the same time ensure the integrity and stability of the supporting structure.

[0029] Both ends of the two semi-circular rings 3 are respectively provided with fixing plates 7. Threaded holes are provided on the surfaces of the fixing plates 7. The fixing plates 7 on the two semi-circular rings 3 are arranged oppositely. After the threaded holes on the fixing plates 7 are aligned, they are fixed by bolts 5. The two semi-circular rings 3 form a buckle, which can ensure that the jack can be firmly locked in place, prevent loosening or displacement, and can play the effect of stable support.
