Description
Technical Field
The utility model belongs to the building field specifically indicates a basement outer wall unilateral formwork structure, is an improvement to the template braced system when basement outer wall concrete placement.
Background
When the basement outer wall is under construction, because the foundation ditch fender pile is narrow and small with the space between the outer wall of treating the construction, it is not enough to leave the construction space of setting up for basement outer wall outside template, takes traditional two side formwork construction degree of difficulty great, can only take unilateral formwork. However, most of the supporting systems of the traditional single-side formwork support adopt a plurality of steel pipes as inclined struts, the required steel pipes are large in specification, the material consumption is large, the construction quality is difficult to guarantee, the supporting strength is insufficient, the formwork expansion is easy to occur, and the concrete forming quality is influenced.
SUMMERY OF THE UTILITY MODEL
Based on the above-mentioned current situation, the utility model discloses a following technical scheme realizes: the utility model provides a basement outer wall unilateral formwork structure, includes the plank sheathing, and the channel-section steel is vertical stupefied once, and two steel pipe are horizontal mainly stupefied, horizontal steel pipe, shaped steel triangular supports stand and shaped steel triangular supports bracing.
Furthermore, the vertical secondary ridges of each channel steel are vertically and uniformly attached to the wood formwork at equal intervals.
Furthermore, the transverse main edges of the double steel pipes are horizontally and equidistantly arranged to be close to the vertical secondary edges of the channel steel.
Furthermore, a transverse horizontal steel pipe is arranged at the transverse main edge of each double steel pipe, U-shaped jacking supports are sleeved at two ends of each transverse horizontal steel pipe, one end of each transverse horizontal steel pipe props against the transverse main edge of each double steel pipe, and the other end of each transverse horizontal steel pipe props against a vertical column of the profile steel triangular support frame.
Furthermore, each horizontal steel pipe is connected by a vertical horizontal steel pipe in the vertical direction.
Furthermore, a steel plate is welded at the bottom of the upright post of the section steel triangular support frame, 4 bolt holes are formed in the steel plate, 4 foundation bolts are pre-embedded in the foundation bottom plate, and the foundation bolts are fastened through the bolt holes in the steel plate by matching nuts.
Furthermore, a U-shaped bolt is arranged at one end above the inclined strut of the profile steel triangular support frame and is connected with the upright post of the profile steel triangular support frame through the U-shaped bolt matched with a steel plate, one end below the inclined strut of the profile steel triangular support frame is fixed on the foundation bottom plate, and the fixing method is the same as that of the upright post of the profile steel triangular support frame.
