Description

Technical Field

[0001] The utility model specifically relates to a floor support mechanism and belongs to the technical field of building construction. Background Art

[0002] Floor support mechanisms play an important role in the construction process of buildings. They are mainly used to support floor slabs and formwork to ensure the smooth progress of the construction process and the structural safety of the building. They are widely used in various construction scenarios, such as high-rise buildings, bridge construction, etc. At the same time, these support mechanisms also play a key role in the concrete pouring process, used to support the concrete and maintain its shape and stability.

[0003] However, the existing floor support mechanism usually uses wooden beams as the supporting secondary beams, and the overall bending resistance is low. At the same time, during the support process, the legs lack stability and are easily mistouched, causing deviation, which affects the support effect. In addition, the legs of the existing support structure are usually integrally formed and can only adapt to floors of the same height. They are not flexible enough and have certain disadvantages during use.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0008] Furthermore, in order to enable the connecting slider to slide on the I-beam through the tension bolts and avoid position displacement of the connecting slider, the tension bolts for fixing the connecting slider on the I-beam are inserted into the connecting through hole and the clearance hole.

[0010] Furthermore, in order to fix the folding support rod and the positioning support rod in connection through the limit pin rod, the limit fixing assembly includes an L-shaped mounting plate, the L-shaped mounting plate is fixedly welded on the positioning support rod, the limit pin rod is slidably mounted on one end of the L-shaped mounting plate, and one end of the limit pin rod is inserted into a limit pin hole provided on the folding support rod.

[0011] Furthermore, in order to enable the limit pin rod to slide on the L-shaped mounting plate by controlling the lifting handle, the lifting handle is fixedly mounted on the other end of the limit pin rod.

[0012] Furthermore, in order to enable the annular gasket to drive the limit pin rod to be fixedly inserted in the limit pin hole through the self-locking spring, the annular gasket is fixedly sleeved on the limit pin rod, and the annular gasket is elastically connected to the L-shaped mounting plate through the self-locking spring.

When in use, the secondary beam 1 of the square steel structure is replaced by the secondary beam 1 of the wooden square structure, thereby improving the bending resistance of the entire supporting structure. At the same time, the positioning support rod 4 can be fixed on the I-beam 2 through the positioning assembly 3, so that in the process of supporting the floor, the positioning support rod 4 can be positioned on the I-beam 2 to avoid positioning. The deviation of the positioning support rod 4 affects the supporting effect of the floor, and a folding support rod 5 is installed at one end of the positioning support rod 4, and the folding support rod 5 is rotatably connected to the positioning support rod 4 through a rotating connection component 6, and a limiting fixing component 7 for limiting the folding support rod 5 is installed on the outer wall of the bottom side of the positioning support rod 4. By rotating the connecting component 6 and the limiting fixing component 7, the folding support rod 5 is fixedly connected to the positioning support rod 4, and the folding support rod 5 can be folded up at the same time, which can be used for supporting floors of different heights and is more convenient to store.

[0023] The positioning assembly 3 includes a connecting slider 301, which is slidably engaged on the I-beam 2. A connecting through hole is provided on the connecting slider 301, which corresponds to the clearance holes evenly provided on the I-beam 2. The connecting through hole and the clearance hole are inserted with tension bolts 302 for fixing the connecting slider 301 on the I-beam 2. When in use, the connecting slider 301 is controlled to slide on the I-beam 2, and the connecting through hole and the clearance hole are made to correspond. When the tension bolts 302 are inserted into the connecting through hole and the clearance hole, the connecting slider 301 can be fixed on the I-beam 2.

[0024] The rotating connection assembly 6 includes a connecting plate 601, and both ends of the connecting plate 601 are rotatably connected to the positioning support rod 4 and the folding support rod 5 through a first rotating axis 602 and a second rotating axis 603 respectively.
