Description

Technical Field

[0001] This utility model belongs to the technical field of post-cast strip construction of roof slabs in building engineering, and in particular provides an independent support column for post-cast strips. Background Technology

[0002] In construction projects, to reduce damage caused by uneven settlement, post-cast strips are often designed in large parking garages and main buildings, where concrete is poured after the settlement has stabilized. According to regulations, post-cast strips require independent support and must be erected separately from the surrounding roof support system. In actual construction, ordinary scaffolding is typically used for the support system, and the formwork and support system at the post-cast strip are not removed until the post-cast strip is poured. This practice results in the post-cast strip formwork and support system being a one-time investment that cannot be reused, increasing project costs. Furthermore, the presence of the support system at the post-cast strip area obstructs access to the parking garage. Utility Model Content

[0003] The purpose of this utility model is to provide an independent support column for post-pouring strips, which solves the problem that the formwork and support system of post-pouring strips cannot be reused in general practices, and also allows for smooth traffic in the garage without affecting subsequent construction.

[0004] This utility model includes 1, 400 400 6. Steel plate; 2. Ф160 4.5 steel columns; 3, 300 300 6. Steel plate; 4. 6mm thick ribbed plate; 5. Ф48 2.8mm steel pipe; 6. Adjustable top support; 7. Formwork system. All steel materials are Q235B. The length of the steel column can be determined according to the clear height of the garage. Two steel plates are welded on both sides of the steel column, with the center of the steel plates aligned with the center of the steel column. Four reinforcing plates are symmetrically welded around the steel pipe. At 300mm... 300 A round hole is made in the middle of the gap in the ribbed plate of the 6 steel plate, and a Ф48 is inserted. 2.8 The steel pipe is welded securely, with a length of 600mm and a height of 300mm. 300 6 steel plate, 60mm.

[0005] When applying, place the independent support column vertically, 400 400 6 steel plates at the bottom, supported by the base plate, 300 300 6 steel plates on top, and at Ф48 2.8 An adjustable top support is inserted into the steel pipe, and the formwork system is installed on top of the top support. After the top slab concrete is poured, the large-area formwork and scaffolding support system can be removed, while the independent support columns and partial formwork remain, providing independent support for the post-pouring strip.

[0006] The beneficial effects of this utility model are:

[0007] 1. It is simple to make and easy to use.

[0008] 2. It can ensure the independent support effect of the post-pouring strip and ensure passage in the garage without affecting subsequent construction.

[0009] 3. The steel columns themselves are reusable and can ensure the reuse of the scaffolding and formwork in the post-pouring strip area, reducing the one-time investment cost. Attached Figure Description

[0014] This utility model includes 1, 400 400 6. Steel plate; 2. Ф160 4.5 steel columns; 3, 300 300 6. Steel plate; 4. 6mm thick ribbed plate; 5. Ф48 2.8mm steel pipe; 6. Adjustable top support; 7. Formwork system. All steel materials are Q235B. The length of the steel column can be determined according to the clear height of the garage. Two steel plates are welded on both sides of the steel column, with the center of the steel plates aligned with the center of the steel column. Four reinforcing plates are symmetrically welded around the steel pipe. At 300mm... 300 A round hole is made in the middle of the gap in the ribbed plate of the 6 steel plate, and a Ф48 is inserted. 2.8 The steel pipe is welded securely, with a length of 600mm and a height of 300mm. 300 6 steel plate, 60mm.

[0015] When applying, place the independent support column vertically, 400 400 6 steel plates at the bottom, supported by the base plate, 300 300 6 steel plates on top, and at Ф48 2.8 An adjustable top support is inserted into the steel pipe, and the formwork system is installed on top of the top support. After the top slab concrete is poured, the large-area formwork and scaffolding support system can be removed, while the independent support columns and partial formwork remain, providing independent support for the post-pouring strip.

[0016] To make the technical solution of this utility model easier to understand, a detailed description is provided below in conjunction with the accompanying drawings and examples of building engineering.

[0017] 1. Complete the fabrication of the independent support columns for the post-cast strip according to the technical plan.

[0018] 2. Install the roof slab formwork and support system according to the construction plan.

[0019] 3. Set up an independent support column every 6 meters on both sides of the post-pouring strip. Erect a formwork system on top of the support column to ensure good connection with the large-area roof slab formwork and support system in the construction plan.

[0020] 4. After the top slab concrete is poured and reaches the required strength, the large-area top slab formwork and support system erected according to the construction plan will be dismantled for reuse. Independent support columns and the top formwork system will remain to independently support the post-pouring strip. The passage problem in the post-pouring strip area will also be resolved, without affecting subsequent construction.
