Abstract
The utility model discloses a steel pipe gypsum mortar waste concrete combination column, including the steel pipe with fill gypsum mortar and the waste concrete piece in the steel pipe, the steel pipe both ends are sealed by the end plate, a plurality of holes of vibrating of having arranged on the steel pipe lateral wall, steel pipe inner wall circumference evenly distributed has many longitudinal reinforcements. The utility model also discloses a method of preparing steel pipe gypsum mortar waste concrete combination column. The utility model discloses the steel pipe gypsum mortar waste concrete combination column of preparation has fast hard, early strong characteristics, can reach the bearing capacity rapidly, and the intensity of member as follows mainly discarded delayed coagulation soil block skeleton provide, can reduce material cost, the gypsum mortar only is used as cementitious material and sealant in addition, and the outside restraint of steel pipe in addition can weaken the weak sureness in interface between gypsum mortar and the waste concrete piece, greatly improves the intensity and the ductility of member.
Description
Technical field
This utility model is related to a kind of steel pipe gypsum mortar discarded concrete coupled column.
Background technology
With the high speed development of building industry, villages and small towns pull down and remove a building for reconstruction with repair, Urban New District and residential quarters continuous
Exploitation and scale construction and public utility newly-built, all can produce substantial amounts of building waste.Additionally, China's part is built
Building structure will reach design life.According to statistics, the annual projects of China account for the 40% of construction project total amount, and every
The quantity that ten thousand square metres of projects can produce building waste is 7000 tons -12000 tons.To make after construction waste crushing
Natural aggregate resource anxiety problem not only can be solved for regenerated aggregate, realize the regeneration of concrete and recycle it is ensured that building
The sustainable development of industry.Both at home and abroad substantial amounts of experimental study is done to regeneration concrete performance, shown regeneration concrete items
Can be good, can be used in Practical Project construction.Current discarded concrete coupled column is typically all that in steel pipe, filling is discarded to be mixed
The materials such as solidifying soil block, cement, coal ash, there is the shortcomings of rate of set is slow, intensity is not good enough in the early time in this coupled column, and fill material
The combination dynamics of material and steel pipe is poor.
Utility model content
In view of the deficiency of background technology, technical problem to be solved in the utility model be provide one kind hard soon, early strong, prolong
Property good and low cost steel pipe gypsum mortar discarded concrete coupled column.
For this reason, this utility model adopts the following technical scheme that to realize：
A kind of steel pipe gypsum mortar discarded concrete coupled column, including steel pipe and the gypsum mortar that is filled in steel pipe and useless
Abandon concrete block, described steel pipe two ends are sealed by end plate.
Described gypsum mortar is made up of water, Gypsum Fibrosum and sand.
Also added with retarder in described gypsum mortar.
The maximum gauge of described waste concrete block is the 1/4-1/3 of diameter of steel tube, the minimum diameter of waste concrete block
For 20-30mm.
The ratio of described water, Gypsum Fibrosum and sand is 0.3：1：1-0.5：1：1.
Described retarder is citric acid.
After technique scheme, the intensity of coupled column is mainly provided by discarded slow setting soil block, and gypsum mortar is used only as
Binder Materials and pointing, it is plastic that gypsum mortar pours rear 20-30 minute, and its intensity can arrive 20-60MPa, has fast
Firmly, early strong feature, and the intensity of component mainly has discarded slow setting soil block skeleton to provide, gypsum mortar is used only as the material that is gelled
Material and pointing, the outside constraint also having steel pipe, can weaken interface between gypsum mortar and waste concrete block weak
Determine, intensity and the ductility of component not only can be greatly improved, but also material cost can be reduced.
Brief description
This utility model has drawings described below：
The structural representation of the steel pipe gypsum mortar discarded concrete coupled column that Fig. 1 provides for this utility model.
Specific embodiment
Include steel pipe 1 and fill out with reference to the steel pipe gypsum mortar discarded concrete coupled column that shown in Fig. 1, this utility model provides
Fill the gypsum mortar 2 in steel pipe 1 and waste concrete block 3, steel pipe 1 two ends are sealed by end plate, and gypsum mortar 2 is by water, Gypsum Fibrosum
With sand composition, the ratio of water, Gypsum Fibrosum and sand is 0.3：1：1-0.5：1：1, mixing water amount is bigger, and intensity is lower, and mobility is got over
Good, also added with retarder in gypsum mortar 2, retarder is citric acid, for adjusting the flocculation time of gypsum mortar 2, discards mixed
The maximum gauge of solidifying soil block 3 is the 1/4-1/3 of steel pipe 1 diameter, and the minimum diameter of waste concrete block 3 is 20-30mm.
With reference to shown in Fig. 1, in order to increase structural strength, described steel pipe side wall is placed with multipair horizontal steel along short transverse
Muscle jack 4, transverse steel 5 passes through in steel pipe 1 and two ends insertion transverse steel jack 4, and described transverse steel 5 and steel pipe 1 wall weld
Connect fixation.In view of the volume of waste concrete block 3 is larger, if cannot be obtained in steel pipe 1 using common reinforcement cage structure
Enough bearing spaces, are therefore contributed in reinforcing bar and coupled column using the structure that transverse steel 5 inserts transverse steel jack 4
Core combines, and improves intensity.
The preparation method of above-mentioned steel pipe gypsum mortar discarded concrete coupled column, comprises the following steps：
（1）Steel pipe one end plate of 1 bottom welding is sealed, then into steel pipe fill diameter of steel tube 1/2-1 it
Between thickness gypsum mortar 2, add the retarder of certain metering as needed in gypsum mortar 2, for adjusting gypsum mortar 2
Flocculation time；
（2）To in steel pipe, alternately throw discarded solidifying soil block 3 and/or rubble and/or cobble and filler plaster mortar；
（3）After gypsum mortar 2 condenses, in steel pipe 1 welded top end plate.
In above-mentioned steps（2）In, throw discarded solidifying soil block 3 and/or rubble and/or cobble and filler plaster in steel pipe 1
Often reach a pair of transverse steel jack 4 position during mortar and in transverse steel jack 4, insert transverse steel 5,
And by outside steel pipe 1, transverse steel 5 is welded on steel pipe 1 wall.The transverse steel inserted mode that the present embodiment provides can avoid
Transverse steel 5 aggregate larger with waste concrete block 3 equal-volume contacts, it is to avoid the loading of impact large volume aggregate, is lifted simultaneously
The bulk strength of coupled column.
