Description
The present invention relates to a kind of concrete fill pipe column, and the preparation method when using it for a part (for example pillar stake) that constitutes building frame.
Fig. 1 is to Figure 3 shows that an example that constitutes the used concrete fill pipe column of a fabric structure part.One of pillar 20 usefulness at inner filling concrete make with the steel outer tube 22 that forms concrete core 24.Outer tube 22 is made up of multistage main body pipe 26 and multistage tube connector 28.Each section tube connector 28 and 26 mutual coaxial connections of two sections adjacent main body pipes.The crossbeam 30 of fabric structure is welded on the outer wall of each tube connector 28, and axial load is delivered on the outer tube 22 from crossbeam 30.In addition, a pair of in inner flange 32 boxing that vertical direction is arranged in parallel at certain intervals on the inwall of tube connector 28, radially stretch into concrete core 24 inwardly, so that axial load is passed to post core 24 from outer tube 22.In this class pillar, the horizontal banding effect of outer tube 22 has improved the compressive strength of concrete core 24, thereby compares with the concrete post commonly used that does not have outer tube, can reduce the cross section of pillar greatly.
But, when making above-mentioned pillar, the trouble in air gap and caking district can appear easily generating in concrete core 24 because of the existence of inner flange 32.For example, when to upright outer tube 22 concrete perfusions when forming concrete core 24,32 one-tenth of inner flanges hinder that air upwards flows smoothly and the obstacle of from outer tube 22, overflowing, the concrete that the result pours into forms air-gap 34(at inner flange 32 soffits and sees Fig. 3).Except that above-mentioned example, during the concrete curing that pours into, inner flange 32 has also become the obstacle of concrete sedimentation, the i.e. obstacle that moves downward because of concrete shrinkage.This situation also can cause forming air-gap 34 below inner flange 32.These air-gaps 34 not only hinder inner flange 32 axial load are passed to post core 24 from outer tube 22, and it also reduces the compressive strength of concrete column core 24.In addition, when the concrete grout sedimentation, flow downward more smoothly than the aggregate that is contained in the concrete because of containing therein slurries, aggregate is easily assembled around inner flange 32, and forms caking distinguish 36(and see Fig. 3 concrete core 24 in).This caking district 36 can reduce the compressive strength of concrete core 24 equally.
Generation for fear of air-gap and caking district when the concrete spouting in outer tube 22 arrives the height of some inner flanges 32, promptly stops to inject concrete.After the hardening of concrete to be injected, concrete perfusion makes it reach the height of next inner flange 32 again.Yet a kind of like this process of concrete perfusion has prolonged the Production Time of pillar 20 greatly.
Therefore, an object of the present invention is to provide the concrete fill pipe column that a kind of inside does not have air-gap and caking district.
Another object of the present invention provides a kind of concrete fill pipe column, and its part that is connected with the crossbeam of framework does not have the reinforcement of evagination, but has superior mechanical strength.

Figure 4 shows that according to concrete fill pipe column of the present invention, it is erected on the pedestal 40, form the part of building frame.This pillar has an outer tube 42, has wherein filled concrete, forms concrete-core column 44.Outer tube 42 is made up of the circular steel pipe fitting 46 of a plurality of coaxial serial connections.Each pipe fitting 46 comprise a tube connector 48 with one with the coaxial main body pipe 50 that links to each other in tube connector 48 lower ends.A plurality of H section steel beam supporting members 52 are welded on the outer wall of tube connector 48, stretch from this radial outward, and the crossbeam of tube connector 48 with building frame coupled together.Every H section steel beam supporting member 52 is formed (see figure 5) by upper flange 56 and lower wing plate 58 and with the web 60 that upper and lower wing plate couples together.In addition, tubular piece 62 is assemblied within the tube connector 48 coaxially, and radially stretches into inwardly in the concrete core 44 so that axial load is delivered on the stem stem 44 from tube connector 48.Tubular piece 62 comprises a pair ofly having that spaced and parallel is arranged and be welded in inner flange 64 and 66 on tube connector 48 inwalls along periphery in vertical direction, and along the strong concrete layer 68 that circumferentially is arranged on tube connector 48 inwalls.Each inner flange 64 and 66 is disks of hollow, radially protrudes inwardly from the inwall of tube connector 48 to form annulus.Last inner flange 64 is positioned on the same horizon of supporting member 52 upper flanges 56, and following inner flange 66 then is positioned on the same horizon of supporting member 52 lower wing plates.
Be clearly shown that as Fig. 5 layer of concrete 68 is made up of three tubular segments, promptly first section 70, second sections 72 and the 3rd sections 74.Under the inner flange 66, its upper surface directly contacts with the whole lower plane of first inner flange 66 under being positioned at for first section 70.This internal perisporium of first section 70 71 is convergents upwards, and the internal diameter that makes the section of winning 70 upper ends and the internal diameter of following inner flange 66 are big to equating, and the internal diameter of first section 70 lower end, promptly the internal diameter of the internal diameter of tubular piece 62 lower ends and tube connector 48 is about equally.Angle theta between internal perisporium face 71 and tube connector 48 axis
1, be preferably between 45 ° to 60 °.Extend for second section 72 between inner flange 64 and the following inner flange 66.This internal diameter of second section 72 roughly equates with the internal diameter of upper and lower flange 64 and 66.Be positioned on the inner flange 64 for the 3rd section 74, its lower surface directly contacts with the whole plane of going up of last inner flange 64.The 3rd section 74 internal perisporium face 75 is downward convergents, make the internal diameter of the 3rd section 74 lower ends and last inner flange 64 internal diameter about equally, and the 3rd section 74 upper end, be the internal diameter of tubular piece 62 upper ends and tube connector 48 internal diameter about equally, the angle theta between internal perisporium face 75 and tube connector 48 axis
2Be preferably between 45 ° to 60 °.In addition, the compressive strength rate of the strong concrete of formation layer of concrete 68 forms the compressive strength height of concrete-core column 44.
Shown in further, there is a separate layer to be clipped between the inwall of concrete-core column 44 and each pipe fitting 46 as Fig. 5, makes stem stem 44 and each pipe fitting 46 unlikely combining.This separate layer is made with the material of pitch, oil, grease, paraffin wax, vaseline, synthetic resin or paper and so on.The thickness of separate layer 76 is limit a stick-slip motion is provided can for concrete-core column 44.When using pitch, thickness is about 20 to 100 microns.In addition, main body pipe 50 is made up of last pipeline section 78 and lower tube section 80.Last pipeline section 78 and lower tube section coaxially but mutually break away from and arrange so that the axial stress of an annular gap 82 of formation reduces device between upper and lower pipeline section 78 and 80. Lower tube section 78 and 80 length should make annular gap 82 be in the middle position on each, promptly are on the moment flex point of main body pipe 50.Because separate layer 76 allows each pipe fitting 46 can move axially the axial width w of annular gap 82 with respect to concrete-core column 44
1When each pipe fitting 46 is subjected to from axial load that the crossbeam 54 of framework passes over is vicissitudinous.Like this, the axial stress that each pipe fitting 46 is born has been reduced in annular gap 82.The axial stress that concrete core 44 bears than pipe fitting 46 bear much bigger because be applied on each pipe fitting axial load by upper and lower inner flange 64 and 66 and layer of concrete 68 pass to concrete core 44.Limited the cross directional variations of concrete core yet be in, thereby increased the compressive strength of pillar effectively than the outer tube 42 under the much smaller stress of concrete core 44.
Shown in Fig. 6 to Fig. 9 is the process of construction drawing 4 concrete fill pipe columns.At first, in factory, be ready to many precast construction pipes 84.Figure 6 shows that a prefabricated structural tube 84.The preparation method of structural tube 84 is as follows: be ready to three tube connectors 48 and three main body pipes 50.By shown in Figure 7 H-shaped steel fine strain of millet supporting member 52 is welded on the outer wall of every ready tube connector 48 then, upper and lower inner flange 64 and 66 is welded on the inwall of ready tube connector 48.Subsequently, as shown in Figure 8, on the inwall of every tube connector 48, make layer of concrete 68.The method for making of this layer of concrete 68 is slowly along its rotational tube connector 48, manual simultaneously strong concrete is spread upon on the inwall of tube connector 48, makes first section 70 and the 3rd section 74 internal perisporium face 71 and 75 that forms convergent respectively at layer of concrete 68.Before smearing concrete, can be along on the inwall of tube connector 48 reinforcing bar being set so that can spread concrete.As the method that need not smear, also can be between concrete injecting tube pattern tool and tube connector 48 inwalls, this cartridge type mould is fixed on the inwall of tube connector 48 removably.Also having a kind of alternative method is to use centrifugal casting method.More particularly, can be with the mould 86 of a pair of frustoconical sheets by on the inwall that is fixed on tube connector 48 removably shown in dotted lines in Figure 8.Tube connector 48 is placed on the whirler, and its axis is horizontal basically, and it is rotated at a high speed along axis.Then quantitative in advance strong concrete is injected between two moulds 86.The result is that the concrete in the tube connector 48 is subjected to being spread over two zones between the mould 86 because tube connector 48 rotates the action of centrifugal force that produces, and forms layer of concrete.In the centrifugal forming process, can between mould 86 and corresponding inner flange, form a space 88, thereby make inner flange 64 and 66 s' concrete when tube connector 48 rotations, flow into the inboard of moulds 86 by space 88.Except space 88, also can make concrete flow into the inboard of mould 86 by the hole (not illustrating in the drawings) of opening in inner flange 64 and 66.After the layer of concrete on every tube connector 48 inwalls 68 formed, barrier material such as pitch or grease be coated in not to be provided in the every tube connector 48 on the inwall of the position of tubular piece 62.Simultaneously also coat identical barrier material, to form separate layer at the inwall of every main body pipe 50.Later, three tube connectors 48 are welded to the upper end of three main body pipes 50 respectively coaxially, form three bodys 46.In this way three bodys 46 making are connected in series coaxially, form precast construction pipe 84.In the process of above-mentioned making precast construction pipe 84 and since layer of concrete 68 inner flange 64 and 66 and H type supporting member 52 be soldered on the tube connector 48 after formation, layer of concrete 68 does not suffer the heating of welding process, thereby prevents that it from sustaining damage.
The precast construction pipe of making is as stated above transported to the building site from factory, earlier a precast construction pipe 84 is erected on the pedestal 40 there, then as shown in Figure 9, concrete is injected in the precast construction pipe 84 of setting to form concrete core 44 with elephant trunk 90.When the top of concrete in the pipe was raised to the internal perisporium face 71 of layer of concrete 68, near the air the internal perisporium face 71 of this convergent successfully upwards flowed along this internal perisporium face 71, thereby the concrete that this internal perisporium face space below 71 all is injected into is full of.In concrete curing process subsequently, concrete shrinks along the internal perisporium face 71 and 75 of layer of concrete 68 downwards smoothly, shown in arrow A among Fig. 5 and B.Like this, concrete just has been full of the space below the internal perisporium face 71 of adjacent layer of concrete 68 fully.As a result, below the internal perisporium face 71 of layer of concrete 68 and below the inner flange 64 and 66, can not produce air-gap and caking district, thereby form a concrete core 44 with reliable compressive strength.Behind the concrete curing that pours into, with suitable cutting tool every main body pipe 50 is divided into upper and lower two section 78 and 80, between them, form annulus 82.Then the crossbeam 54 of building frame is coupled together with the H type supporting member 52 of precast construction pipe 84 respectively.Then another root precast construction pipe 84 is received on the top of having poured into concrete precast construction pipe 84 coaxially.After this, repeat above-mentioned each step, make the concrete fill pipe column from concrete perfusion to connection precast construction pipe by the predetermined number of plies.
Can make the concrete fill pipe column with being less than or replacing above-described precast construction pipe 84 more than the precast construction pipe of three pipe fittings 46.In addition, can make another first concrete segment 70 and another the 3rd concrete segment 74 under the last inner flange 64 He on the following inner flange 66 respectively, so that replace second section 72 of layer of concrete 68.In addition, the concrete tube body of also can application of carbon fibres reinforcing replaces main body pipe 50.This body is made up of hollow cylindrical cement matrix and high-strength carbon fiber.Carbon fiber twine to form with the coaxial circle shape of cement matrix and imbeds cement matrix.The method of making this body is the carbon fiber circle to be immersed in to make carbon fiber circle formation drum in the cement paste of cement powder diameter less than the carbon fiber diameter.The concrete main pipe's of this carbon fiber reinforcement young's modulus of elasticity equates substantially with the young's modulus of elasticity of concrete core 44, thereby concrete core 44 is played effective banding effect, even neither establish separate layer 76 thereon, effective too when also not reducing the circumferential weld 82 of little stress.
Figure 10 and 11 is depicted as an alternative embodiment of the invention.Each pipe fitting 92 leaves layout mutually in this structure, forms annulus 82 between per two adjacent pipe fittings 92.Each pipe fitting has a tubular piece to embed the upper end of pipe fitting 92.As Figure 11 clearly shown in, this tubular piece is made up of following part: inner flange 66 that is welded in pipeline section 92 upper ends and one are positioned at the layer of concrete 70 below the inner flange 66.Separate layer 76 is clipped between that part of inwall that concrete core 44 and each pipe fitting 92 do not cover by tubular piece 94.Be welded with several supporting members 52 of being connected with building crossbeam 54 of being used on the outer wall of each pipe fitting 92.Be provided with between the pipe fitting 92 that each pipe fitting 92 is adjacent one be basically the annular separator 96 so that annulus 82 is closed.These separator 96 usefulness elastomeric materials are made, for example rubber or synthetic resin.For example epoxy resin or similar substance stick to separator 96 lower end of each pipe fitting 92 with cementing agent, this concrete fill pipe column is made of several precast construction pipes, every precast construction pipe comprises pipe fitting 92, tubular piece 94, supporting member 52, separate layer 76 and separator 96, and these members are all made in factory.Then the precast construction pipe is transported to the building site, carry out coaxial connection by the described method of a last embodiment.When a precast construction pipe being connected to the prefabricated pipe upper end of concrete perfusion, can inserting the girth member 98(that is cylinder frame shape in the bonding pad of two prefabricated pipe and see Figure 12) thus the mechanical strength of connecting portion is improved.More particularly, as shown in figure 12, the Lower Half of girth member 98 is embedded in the concrete core 44 that forms in the following prefabricated pipe 100, the first half of girth member 98 is stretched from the upper end of a following prefabricated pipe like this, then top prefabricated pipe 102 coaxially on the frame prefabricated pipe 100 below, thereby make the first half of girth member 98 prefabricated pipe 102 above inserting.Concrete perfusions in the prefabricated pipe 102 that can be upward after connecting.
Figure 13 shows that another embodiment of the present invention.Its pipe fitting 104 is by several tubes unit 106 coaxial composing in series.Every unit of pipe 106 is made up of tube connector 48 and the coaxial main body steel pipe 108 that is welded in tube connector 48 lower ends.Tube connector 48 has a plurality of H type supporting members 52 and upper and lower inner flange 64 and 66.The crossbeam 54 of building frame is connected with tube connector by H-type supporting member.Main body pipe 108 has the stress of being made up of several cannelures 118 that forms and reduces device on its outer wall.The number of cannelure 118 and axial width w thereof
2To determine according to the design condition of pillar with radial depth.On the inwall of entire body pipe 108, and on the remainder inwall of the tube connector 48 except that upper and lower inner flange 64 and 66 s' inner wall section, scribble separate layer 76.Each pipe fitting 104 also has a layer of concrete 110.This layer of concrete 110 comprises all two drum-shaped sections coaxial with pipe fitting 104, promptly first section and second section 112,114.Be positioned at for first section 112 below the following inner flange of nethermost unit of pipe 106, this upper end of first section 112 contacts with the whole lower plane of first inner flange 66 of nethermost unit of pipe 106.This first section 112 has a upwards internal perisporium face 71 of convergent.Second section following inner flange 66 from nethermost unit of pipe 106 extends to the last inner flange 64 of uppermost unit of pipe 106.This internal diameter of second section 114 equates with the internal diameter of upper and lower inner flange 64,66 haply.The upper end of the tube connector 48 of uppermost unit of pipe 106, and the inside, the bottom of nethermost unit of pipe is provided with layer of concrete 110.
Figure 14 and 15 is depicted as the manufacturing process of concrete fill pipe column shown in Figure 13.At first, in factory, be ready to many precast construction pipes 120.Such precast construction pipe 120 is shown among Figure 14, and its production routine is as follows: be ready to many tube connectors 48 and Duo Gen main body unit of pipe 108.H-type supporting member 52 is welded on the outer wall of every ready tube connector 48, more upper and lower inner flange 64,66 is welded on the inwall of every ready tube connector 48.Go out cannelure 118 in the turning of the middle part of every ready main body unit of pipe 108.Coat barrier material to form separate layer 76 at the inwall of every tube connector 48 and every main body unit of pipe 108.Subsequently by the upper end that each root tube connector 48 is welded on coaxially each root main body unit of pipe 108 respectively shown in Figure 15 to form unit of pipe 106.Then the unit of pipe of making by described process 106 is contacted coaxially and weld to form pipe fitting 104.Be that the pipeline section of making is coated layer of concrete 110 then with centrifugal casting.More particularly, frustoconical sheets hollow mould 86 by mode shown in dotted lines in Figure 14, is fixed on the inwall of nethermost unit of pipe 106 removably, pipe fitting 104 is placed on the slewing it is rotated at a high speed around its axis.Then the strong concrete that will measure in advance is added in the zone between the upper flange of mould 86 and uppermost unit of pipe 106.The result places the concrete of pipeline section 104 to form layer of concrete shown in Figure 14 110.In said process and since layer of concrete 110 inner flange 64 and 66 and H-type supporting member 52 weld after formation, layer of concrete 110 does not suffer the heating of welding process, thereby prevents that layer of concrete 110 from sustaining damage.
The precast construction pipe made as stated above 120 is transported to the building site from factory, couple together coaxially one by one by method described in first embodiment there.In the present embodiment, because the upper and lower inner flange 64 and 66 between the lower flange 66 of the upper flange 64 of uppermost unit of pipe 106 and nethermost unit of pipe 106 all is embedded in the layer of concrete 110, below all following inner flanges 66, needn't make the internal perisporium 71 of convergent.So, to compare with precast construction pipe 84, the manufacturing efficient of precast construction pipe 120 has improved.Also have, because layer of concrete 110 is neither in the upper end of the tube connector 48 of uppermost unit of pipe 106, not in the bottom of nethermost unit of pipe, layer of concrete 110 can not be subjected to the influence of the heat that produces when precast construction pipe 120 welded yet.
On inner flange 64 on the uppermost unit of pipe 106, the 3rd section of layer of concrete can be set, the 3rd section lower end directly contacts with the whole plane of going up of the last inner flange 64 of uppermost unit of pipe 106, and makes the 3rd section to have an internal perisporium face 75 of convergent down.
Shown in Figure 16 is a kind of remodeling form of the concrete fill pipe column among Figure 13.In this pattern, every main body unit of pipe 122 usefulness carbon fiber reinforced concrete above-mentioned is made.The upper and lower end section 124 of every main body unit of pipe 122 and 126 external diameter are littler than the external diameter in main body pipe stage casing.The upper end section 124 of main body unit of pipe 122 is inserted in the adjacent with it thereon tube connector 48 coaxially, and its lower end section 126 then is inserted in its adjacent with it down tube connector 48 coaxially.A coaxial connection of lower end that has cylindrical shape connector 128 with the main body unit of pipe 122 in bottom of each pipe fitting 130 of inner flange 66, and on the uppermost tube connector 48 of the pipe fitting 130 that its lower end welding is adjacent with it in its lower section.Pipe fitting 130 uppermost tube connectors 48 and connector 128 tighten up them mutually around the axially extended bracing piece of doing of distributing of the axis isogonisms of pipe fitting 130 132 by many, so just with other tube connectors 48 between uppermost tube connector 48 and connector 128 and other main body unit of pipe 122 overlappings tighten together.There is screw the upper and lower end of every bracing piece all turning, and passes all inner flanges 64 and 66 of pipe fitting 130.The threaded upper end of every bracing piece 132 upwards passes from the hole of the last inner flange 64 of uppermost tube connector 48, is fixed on by nut 134 on the last plane of inner flange 64.On the other hand, the threaded bottom of every bracing piece 132 passes downwards from the hole of the inner flange 66 of connector 128, is fixed on by nut 136 on the lower plane of inner flange 66.First section 112 of layer of concrete 110 is positioned under the inner flange 66 of connector 128, second section 114 of layer of concrete 110 then the inner flange 66 of connector 128 and topmost a tube connector 48 between the inner flange 64.Separate layer neither is set on each root pipe fitting 130 does not also reduce the groove of little stress.Make such concrete fill pipe column, in factory, make many precast construction pipe 138(earlier and see Figure 17).The method of the preparation method of every precast construction pipe 138 and making precast construction pipe 120 is that tube connector 48 and main body unit of pipe 122 replace stacked then being connected and fixed with connector 128 and bracing piece 132 much at one.Layer of concrete 110 is made the method formation of back with centrifugal forming at whole pipe fitting 130.After precast construction pipe 138 was made, bracing piece 132 and nut 134 and 136 all be embedded in the layer of concrete 110.
An alternative embodiment of the invention as shown in figure 18.Each pipe fitting 140 is made up of steel tube connector 142 and the main body pipe 50 that is welded in tube connector 142 lower ends coaxially.One tubular piece that forms one is with it arranged in the tube connector 142, and promptly tube connector 142 has the internal perisporium face 71 and 75 of the first and second convergent shapes respectively at its upper and lower end.Therefore the internal diameter of the upper and lower end of tube connector 142 equates that with the internal diameter of main body pipe 50 internal diameter of tube connector 142 middle parts is then much smaller than the internal diameter of main body pipe 50.Every tube connector 142 all is welded with several supporting members 52, and has all coated separate layer 76 on the total inner surface of every main body pipe 50.Needn't say that stress reduces groove 82 and opens middle part at every main body pipe 50.Make tube connector 142 with for example centrifugal casting, so its inwall is coarse.The length of every tube connector 142 is than the height H of each supporting member 52
1Vertical length L with each convergent shape internal perisporium face
2Summation long.Behind the precast construction pipe for preparing many tube connectors that alternately are serially connected 142 that include predetermined radical and main body pipe 50, they are transported to the building site, connect together one by one by the method identical with pillar preparation method shown in Figure 4.In this concrete fill pipe column, can prevent the generation in air-gap and caking district equally, to compare with a last embodiment, the mechanical strength of every tube connector 142 is by height.
