Connecting structure of casting rod and floor embedded steel pipe

Abstract

The utility model discloses a casting rod and floor embedded steel pipe connecting structure. The structure comprises a lower floor slab; the upper-layer floor slabs are arranged on the lower-layer floor slabs at intervals; the outer side of the lower floor slab is fixedly connected with the bottom of a scaffold, and the scaffold is connected with the lower floor slab through an adjustable and movable casting rod; the upper floor slab is provided with a non-straightened cable-stayed steel wire rope which is connected with the casting rod. The scaffold is connected and reinforced into the lower floor slab through the casting rods, when the scaffold inclines away from the outer side of the lower floor slab, the casting rods conduct reinforced connection with the lower floor slab as stress, the stress generated when the scaffold is connected and reinforced is prevented from being transmitted to the poured and uncured upper floor slab, and the problem that when the upper floor slab is not cured to the set strength, the scaffold cannot be damaged is solved. And the cable-stayed steel wire ropes are used for reinforcing connection to damage the upper floor slab.

Description

Technical Field

[0001] The utility model relates to a connecting structure of a casting rod and a pre-buried steel pipe on a floor, belonging to the technical field of building construction. Background Art

[0002] When a building is under construction, scaffolding needs to be set up outside the building to support workers and materials. When the building is raised by pouring new floors, the scaffolding also needs to be raised to adapt. In order to ensure the stability of the scaffolding after the increase, the scaffolding needs to be connected and strengthened.

[0003] The existing scaffolding connection reinforcement is shown in Chinese patent announcement number CN205777422U, and the disclosed technology is: the inclined steel wire rope is tied with the upper floor as the force point; although the scaffolding connection can be strengthened after the upper floor is solidified, when the upper floor is not solidified to the set strength, the inclined steel wire rope reinforcement connection will damage the upper floor. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a connection structure between a casting rod and a pre-buried steel pipe on a floor.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a connecting structure of a casting rod and a pre-buried steel pipe on a floor, comprising:

[0007] Lower floor slab;

[0008] An upper floor slab spaced above a lower floor slab;

[0009] The outer side of the lower floor is fixedly connected to the bottom of the scaffolding.

[0010] The scaffolding is connected to the lower floor slab by a cast rod that can be adjusted and moved;

[0011] The upper floor is installed with an unstraightened inclined steel wire rope connected to the casting rod.

[0012] A short steel pipe is embedded in the lower floor slab away from the scaffolding. A casting rod is installed on the short steel pipe through a scaffolding clamp A. The casting rod can be adjusted and moved on the short steel pipe through the scaffolding clamp A.

[0013] The casting rod is connected to the scaffold through the scaffold clamp B, and the casting rod can be adjusted and moved on the scaffold through the scaffold clamp B.

[0014] The outer side of the lower floor slab is fixedly connected to the bottom of the scaffolding by embedded bolts.

[0015] A wall connection piece and a double-ear lifting ring are pre-buried in the upper floor slab, and an oblique steel wire rope in an unstraightened state is installed between the double-ear lifting ring and the casting rod.

[0016] The beneficial effect of the utility model is that the scaffolding is connected and strengthened to the lower floor slab by means of a casting rod. When the scaffolding is tilted away from the outer side of the lower floor slab, the casting rod is used as the force-bearing reinforcement connection of the lower floor slab, thereby avoiding that the force of the scaffolding connection reinforcement is transmitted to the poured but unsolidified upper floor slab, thus solving the problem that when the upper floor slab is not solidified to the set strength, the inclined steel wire rope reinforcement connection will damage the upper floor slab. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic diagram of the utility model;

[0018] In the figure: 1-lower floor; 11-embedded bolts; 2-upper floor; 3-scaffolding; 4-embedded short steel pipe; 41-scaffolding clamp A; 42-scaffolding clamp B; 5-casting rod; 6-wall connecting piece; 7-double-ear lifting ring; 8-oblique-stayed wire rope. DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0020] like Figure 1 shown.

[0021] The present invention discloses a structure for connecting a casting rod and a pre-buried steel pipe on a floor, comprising:

[0022] The lower floor slab 1 has been cast and solidified, and the upper floor slab 2 has been cast but not solidified. The outer side of the lower floor slab 1 is fixedly connected to the bottom of the scaffolding 3 by embedded bolts 11. A pre-embedded short steel pipe 4 is embedded in the lower floor slab 1 away from the scaffolding 3. The pre-embedded short steel pipe 4 is equipped with a casting rod 5 through a scaffolding clamp A41. The casting rod 5 can be adjusted and moved on the pre-embedded short steel pipe 4 through the scaffolding clamp A41.

[0023] The casting rod 5 is connected to the scaffold 3 through the scaffold clamp B42, and the casting rod 5 can be adjusted and moved on the scaffold 3 through the scaffold clamp B42. When the scaffold 3 is lifted to the uncured upper floor 2, it can be connected and strengthened by the casting rod 5, and the force is only distributed to the lower floor 1.

[0024] The upper floor slab 2 that has been cast but not solidified is pre-buried with a wall connection piece 6 and a double-ear lifting ring 7. An unstraightened inclined steel wire rope 8 is installed between the double-ear lifting ring 7 and the casting rod 5. After the upper floor slab 2 solidifies, the inclined steel wire rope 8 is straightened by adjusting the casting rod 5 downward, so that the casting rod 5 and the straightened inclined steel wire rope 8 are used to connect and strengthen the scaffolding 3. At this time, the force can be divided into the lower floor slab 1 and the upper floor slab 2. After the upper floor slab 2 solidifies, the scaffolding 3 is connected to the wall connection piece 6 through a connecting rod for horizontal connection and strengthening.

[0025] When the scaffolding 3 is on the outside of the lower floor 1 and the upper floor 2 of the building body, the scaffolding 3 is connected and reinforced to the lower floor 1 through the casting rod 5. When the scaffolding 3 tilts away from the outside of the lower floor 1, the casting rod 5 is used to strengthen the connection with the lower floor 1 to avoid the force of the reinforced connection of the scaffolding 3 being transferred to the cast but not solidified upper floor 2, thus solving the problem that when the upper floor is not solidified to the set strength, the inclined steel wire rope reinforcement connection will damage the upper floor.
