Abstract
The utility model provides a combined recyclable foundation pit supporting inner supporting upright column formed by connecting profile steel and concrete piles in a split joint mode. After construction is finished, profile steel upright columns on bottom plates of a foundation pit are recycled. As parts which can not be recycled are made into concrete upright columns to the uttermost degree, and the parts which can be recycled are made into steel structures, the combined recyclable foundation pit supporting inner supporting upright column greatly lowers the use amount of steel, saves cost, and is low in carbon and environment-friendly.
Description
Technical field
The utility model relates to technical field of civil engineering, the column that particularly uses in the pattern foundation pit supporting structure inner supporting structure.
Background technology
In foundation pit supporting construction, inner support supporting and protection structure is commonly used to be supported, inner supporting structure is provided with the column for vertical carrying inner support, the normal conditions lower pillar stand adopts steel structural upright column, and in order to have higher bearing capacity, column lower end inserts base plate of foundation pit and obtains enough bearing capacities to get off usually, but after the base plate of foundation pit construction is complete, the upright steel structure on base plate top can only be cut away recovery, and the following column of base plate can't reclaim, and has caused the waste of steel.
The utility model content
Technical problem to be solved in the utility model is, overcomes that inner support provides a kind of novel callable column of novel inner support that can save steel with the waste problem that column exists in the existing pattern foundation pit supporting structure.
In order to address the above problem, the technical solution of the utility model is such:
The callable pattern foundation pit supporting structure inner support of a kind of combined type column, column is spliced by top shaped steel and bottom precast reinforced concrete pile, and described precast reinforced concrete pile is arranged on below the base plate of foundation pit, and the above shaped steel of the complete rear base plate of foundation pit of supporting reclaims.
Sectional shape is rectangle or foursquare H shaped steel, and precast reinforced concrete pile is square pile or circle stake.
The joint of shaped steel and precast concrete pile is positioned at the below on base plate of foundation pit plane, and joint is apart from base plate of foundation pit plane 300mm at least.
The bottom of shaped steel is provided with sealing piece, and sealing piece is in the upper plane of base plate of foundation pit and the position between the lower plane.
The contact surface place of precast concrete pile and shaped steel is reserved with splicing and uses the shaped steel joint, utilizes the splicing of this shaped steel joint and shaped steel column.
Beneficial effect, the callable pattern foundation pit supporting structure inner support of a kind of combined type described in the utility model column can not recovery section be made concrete column to greatest extent, and recyclable part is made steel work, greatly reduce the consumption of steel, low-carbon environment-friendly is saved cost.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is that pattern foundation pit supporting structure inner support described in the utility model is applied in the foundation ditch schematic internal view with recyclable column.
Fig. 2 is single column supporting structural schematic diagram described in the utility model.
Fig. 3 is the foundation ditch schematic internal view after column reclaims.
Fig. 4 is the only structural representation of surplus concrete column after steel structural upright column reclaims.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, foundation ditch inside has inner support 1, and inner support is prestressing force fish belly sill tool-type combination formula inner support, because the inner support span is excessive, need to be provided with in inner support bottom the column 2 for the carrying inner support, column 2 is connected with bracket by crossbeam 3 and is connected inner support.
Waterproof construction for the ease of base plate of foundation pit 5, infiltration is leaked around preventing column 2, concrete column 22 need to be arranged on below the base plate of foundation pit, concrete shaped steel column 21 and the splicing seams of concrete column 22 are positioned at the below of base plate of foundation pit 5 lower planes, and splicing seams is apart from base plate of foundation pit lower plane 300mm at least.And need to be provided with in the bottom of shaped steel column 21 sealing piece 23, sealing piece 23 is in the upper plane of base plate of foundation pit 5 and the position between the lower plane.Sealing piece 23 is for being welded on shaped steel column 21 steel plate on every side, and steel plate plays the effect of dash, prevents that moisture is from shaped steel column 21 and base plate of foundation pit 22 joint leadkages.
Referring to Fig. 3 and Fig. 4, build complete at the foundation ditch basement bottom board, the outer wall of basement construction is complete, and after concrete reaches design strength, removing upper steel supports and steel post 21, be positioned at the basement bottom board upper surface from steel post 21 and cut off namely recyclablely, be positioned at part steel post and the sealing piece 23 of basement bottom board and be positioned at the following concrete column 22 of basement bottom board and then stay foundation ditch.
The callable pattern foundation pit supporting structure inner support of a kind of combined type described in the utility model column can not recovery section be made concrete column to greatest extent, and recyclable part will be made steel work, greatly reduce the consumption of steel, and low-carbon environment-friendly is saved cost.The advantage that performance precast reinforced concrete pile volume is large, cost is low, distortion is little, bearing capacity is high places it in the column bottom, increases the bearing capacity of column.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not subjected to the restriction of above-mentioned example; that describes in above-mentioned example and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
