Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the invention.

The invention discloses a fabricated concrete plate with high shock resistance and support in the length direction and the lateral direction, a template and a production method.

In a first aspect, a high-seismic capacity fabricated concrete panel includes: a concrete body 1 and a support 2.

The support member 2 is arranged in the concrete body 1, extends along the length direction of the concrete body 1, and bends to a preset radian along the lateral direction of the concrete body 1, and the support member 2 can be a steel bar with a plurality of discontinuous spiral protrusions on the side wall.

The distance from the middle of the support member 2 to the side of the concrete body 1 is smaller than the distance from the two ends of the support member to the side of the concrete body 1.

As shown in fig. 1, the support member 2 extends in the longitudinal direction of the concrete body 1 in the concrete body 1 and bends to a predetermined arc in the lateral direction of the concrete body 1, thereby supporting the longitudinal direction and the lateral direction of the concrete slab and improving the seismic resistance of the concrete slab.

In a further embodiment of the first aspect, the distance of the support 2 to the edge of the concrete body 1 is at least 30 mm.

The falling off of the concrete due to the excessively low thickness can be prevented by reserving a sufficient thickness for the concrete body 1.

The central angle of the support 2 bent to the predetermined radian is greater than or equal to 3.5 degrees and less than or equal to 5.1 degrees, the central radius of the radian is greater than or equal to 47581mm and less than or equal to 76801mm, wherein the central radius of the radian decreases when the central angle increases, and the central radius of the radian increases when the central angle decreases, taking the total length of the existing standard concrete slab as 4200mm as an example, as shown in fig. 1, the central angle of the support 2 bent to the predetermined radian is 3.5 degrees, and the central radius of the radian is 76801 mm.

Through the central angle degree of the crooked predetermined radian of restriction support piece 2, can avoid the central angle undersize of support piece and the support degree that provides is not enough, can also avoid the central angle too big and cause the damage to support piece.

Specifically, in the above embodiment, the radius of curvature R at which the support member is bent by a predetermined arc satisfies:

R＞0.25×（L ² /（H-2M））

m is the minimum distance from the support to the edge of the concrete body, L is the length of the support, and H is the thickness of the support.

For a support member with a length L and a thickness H, if the rule specifies that the minimum distance between the support member and the side edge of the concrete main body is M (or the minimum depth of the support member embedded), parameters of the support member, especially the bending radian of the support member, need to be set according to the size of the concrete main body.

From the position of the support within the concrete body, it is known that:

let the distance from the connecting line of the two ends of the support to the maximum bending point be x

∆x+M≤0.5H，∆x=R-Rcoso，sins=L/2R；

Solving to obtain:

R-Rcosθ+M≤0.5H

since theta is small, cos theta can be expanded using taylor's formula,

R-R+L ² /8R + L ⁴ /（8*4*R ³ ) Less than or equal to 0.5H-M; thereby having

L ² /8R＜L ² /8R + L ⁴ /（8*4*R ³ ）≤0.5H- M

Therefore, the method comprises the following steps: r > 0.25 × (L) ² /（H-2M））。

Therefore, the radian of the supporting piece can be adjusted according to the basic parameters of the concrete body and the preset minimum depth of the supporting piece specified by engineering, so that the arc-shaped supporting piece can be conveniently and quickly manufactured.

According to one aspect of the application, at least a fiber concrete layer extending in the length direction is provided within the concrete body, the fiber concrete layer comprising steel fibers, glass fibers and basalt fibers.

For the earthquake-proof performance, besides the design from the structural aspect, the design can also be carried out from the material, for example, the earthquake-proof performance of the concrete main body is improved by improving the earthquake-proof performance of the material composing the concrete main body, for example, the earthquake-proof fiber is doped in the concrete main body to form a fiber concrete layer extending along the plane of the concrete main body, and the steel fiber, the glass fiber GRC or the basalt fiber can be doped. Fibers can be fully doped in the concrete body, the seismic performance is relatively strong, but the cost is high, and finite element simulation shows that the seismic effect does not occur on part of the fibers. It is thus possible to form at least one fibre layer in the concrete body extending in the plane of the concrete body. For example, in casting concrete, after a portion is cast, a fiber layer is made, and then a concrete layer is cast again, and the fiber layer may be two to three layers.

According to an aspect of the application, be provided with first antidetonation stirrup and second antidetonation stirrup between the adjacent support piece, first antidetonation stirrup extends along length direction, and second antidetonation stirrup extends along the side direction, and first antidetonation stirrup and second antidetonation stirrup include the antidetonation muscle of at least one clockwise coiling and the antidetonation muscle of at least one anticlockwise coiling respectively, and the antidetonation muscle of clockwise coiling forms the cross section with the antidetonation muscle of anticlockwise coiling and is oval-shaped steel reinforcement cage, and steel reinforcement cage has the hole of rhombus.

In other words, along a certain central shaft in the length direction, two anti-seismic ribs are respectively wound from one end according to the clockwise direction and the anticlockwise direction, and the joint of the two anti-seismic ribs is welded or bound and fixed. And two anti-seismic ribs are wound clockwise and anticlockwise along the transverse direction perpendicular to the length direction, and the joint of the two anti-seismic ribs is welded or bound and fixed. Through the mode, the anti-seismic stirrup or the cylindrical anti-seismic cage is formed.

During production, the reinforcement cage can be manufactured by adopting a winding cage knitting machine, and the reinforcement cage can also be wound into a cylindrical anti-seismic cage by adopting a rhombic reinforcement net meeting performance indexes. During manufacturing, one reinforcement cage can be contained in the other reinforcement cage, and the addressing can also be staggered, so that the reinforcement cage which longitudinally and transversely contains clockwise anti-seismic ribs and anticlockwise anti-seismic ribs is formed. Those skilled in the art will appreciate that the above approaches are all possible and that differences in fabrication time and cost may exist.

Because the supporting piece is arranged, the reinforcement cage can be made of the steel bars with smaller diameters, and only the moment resisting vibration is needed.

Therefore, in the embodiment, the method of winding the rhombic net through the winding machine or the method of manufacturing/purchasing the rhombic net and then winding the rhombic net into the elliptic cylindrical surface is convenient, the production efficiency is greatly improved, and meanwhile, the production efficiency and the production cost are not influenced.

In the second aspect, the existing supporting member 2 basically uses the linear steel bar, if the steel bar with the predetermined curvature is directly purchased from the non-standard member, the purchasing cost is too high, and after the linear steel bar is purchased, the steel bar is bent to the predetermined curvature, the required processing time is too long, the production efficiency is low, additional processing equipment needs to be purchased by using the machine processing, and the purchasing cost is too high.

In order to solve the above problems, a formwork for a fabricated concrete panel of the first aspect comprises: a positioning plate 3, a shaping plate 4, a pressing plate 5 and a counter-pulling component 6.

One end of the fixed plate 4 is connected with the positioning plate 3, and a rectangular cavity is arranged in the fixed plates 4 in an enclosing mode.

The other end of clamp plate 5 and boarding 4 is connected, has still seted up a plurality of on the clamp plate 5 and has filled hole and exhaust hole, when the in-service use, pours cement from filling the downthehole, exhausts from the exhaust hole.

The counter-pulling component 6 penetrates through the positioning plate 3 and the pressing plate 5, as shown in fig. 2, the counter-pulling component 6 can comprise a threaded rod penetrating through the positioning plate 3 and the pressing plate 5, and nuts screwed at two ends of the threaded rod, because the assembled concrete slab can be provided with a plurality of hollow pipes to process a plurality of hollow cavities in the assembled concrete slab to increase the bending resistance of the assembled concrete slab during actual production, and the assembled concrete slab is convenient to transport, the counter-pulling component 6 can be partially penetrated in the hollow pipes by the threaded rod of the counter-pulling component 6 as shown in fig. 2 during actual production, the counter-pulling component 6 is taken out after the concrete slab is solidified, the hollow pipes are hidden in fig. 2 in order to show the position relation of the technical characteristics to be protected, in the actual application, a steel bar with a length higher than that of the hollow pipes can be selected as the support 2, when the steel bar is bent to a position with a preset radian, the hollow pipe is abutted to a preset position with the positioning plate 3 and the pressing plate 5, so that the hollow pipe is closed, and concrete is prevented from entering the hollow pipe.

It is also possible to fix the positions of the positioning plate 3, the setting plate 4 and the pressing plate 5 using screws while the counter-pulling assembly 6 bends the reinforcing bars to a predetermined arc position, and then remove the counter-pulling assembly 6.

The opposite sides of the pressing plate 5 and the positioning plate 3 are provided with positioning holes 31 for fixing the supporting members 2, i.e., the supporting members 2 are inserted into the positioning holes 31.

In the working state, the opposite pulling component 6 applies force towards the rectangular cavity to the positioning plate 3 and the pressing plate 5, so that the total distance between the positioning holes 31 at the opposite sides of the positioning plate 3 and the pressing plate 5 is smaller than the total length of the supporting piece 2, and the supporting piece 2 is bent by a preset radian.

The working principle is as follows: the reinforcing bar will produce a certain amount of bending deformation in production and transportation, and to the in-process of the effort that draws subassembly 6 to locating plate 3 and clamp plate 5 to exert on this basis, locating plate 3 and clamp plate 5 exert the extrusion force to the both ends of reinforcing bar, can enlarge the bending deformation of reinforcing bar itself.

Through the effort of 6 pairs of locating plates 3 and 5 applys of clamp plate of drawing the subassembly, reach the effect that makes 2 crooked predetermined radians of support piece, only need increase to drawing subassembly 6 and can make 2 crooked predetermined radians of support piece in the template of assembly, can need not to purchase the reinforcing bar that has predetermined radian of nonstandard piece, make the support piece 2 that has crooked predetermined radian in concrete body 1 under the unchangeable circumstances of assurance purchasing cost, also need not substep processing reinforcing bar, required process time has been reduced, the machining efficiency is improved.

And the pressing force on the concrete can be increased through the opposite pulling component 6, so that the density of the concrete is improved.

In a further embodiment of the second aspect, the reinforcing steel bars with the predetermined curvature are obtained by only amplifying the bending deformation of the reinforcing steel bars, and although the reinforcing steel bars can support the concrete slab in the length direction and the lateral direction, the seismic capacity of the concrete slab is improved, the bending direction of the reinforcing steel bars is not fixed, so that the supporting force provided by the reinforcing steel bars to the concrete slab in each direction is not fixed, and the stability of the concrete slab with the increased seismic capacity is poor.

In the embodiment shown in fig. 3, the positioning hole is an oblique hole having an inner diameter larger than the diameter or thickness of the support member 2.

The working principle is as follows: the supporting member 2 is first inserted into the inclined hole, and the supporting member 2 is guided to be bent in a lateral direction to be bent in a predetermined direction while the distance between the positioning plate 3 and the pressing plate 5 is reduced.

In the embodiment shown in fig. 4, the opposite ends of the positioning holes 31 of the positioning plate 3 and the pressure plate 5 are opened with guide grooves 32, and the width of the guide grooves 32 is larger than the predetermined value of the outer diameter dimension of the support member 2.

The bottom wall of the positioning hole 31 is an inclined surface, and as shown in fig. 2 and 4, the depth of the positioning hole 31 is greater than that of the guide groove 32, so that the end of the support member 2 can be inserted into the positioning hole 31 to fix the end of the support member 2.

In operation, the end of the support 2 abuts the ramp.

In the process that the positioning plate 3 and the pressing plate 5 are displaced towards the direction of the rectangular cavity, the guide grooves 32 guide the bending direction of the support member 2, so that the reinforcing steel bars can be bent along the opening direction of the guide grooves 32.

The guide groove 32 is arranged to guide the bending direction of the support member 2, so that the bending direction is fixed, the supporting force provided by the reinforcing steel bars to the concrete slab in each direction can be fixed, and the stability of the increased shock resistance is improved.

In the further embodiment of the second aspect, because the outer side of the steel bar is provided with a plurality of discontinuous thread-shaped protrusions, when the guide groove 32 guides the steel bar, the protrusions are clamped at the edge of the guide groove 32 and cannot enter the guide groove 32, and the steel bar is bent towards other directions, so that the positioning plate 3 and the pressing plate 5 are damaged in the process of bending towards other directions.

In order to solve the above problem, a guide slope 33 is provided at a boundary between the inner wall of the guide groove 32 and the positioning plate 3 or the pressing plate 5.

In the process that the positioning plate 3 and the pressing plate 5 are displaced towards the rectangular cavity direction, the part of the support member 2 close to the middle gradually enters the guide groove 32, and in the process that the support member 2 enters the guide groove 32, the support member 2 is firstly abutted against the guide slope 33 of the guide groove 32 and then is guided into the guide groove 32 by the guide slope 33.

In a further embodiment of the second aspect, in the prior art, concrete is poured into the rectangular cavity and then stands still for a preset time to wait for the natural cooling of the concrete, but air is mixed in the concrete pouring process into the rectangular cavity, the concrete close to the reinforcing steel bars can obtain stronger shock resistance by means of the supporting force of the reinforcing steel bars, but the part close to the qualitative plate far away from the reinforcing steel bars is easy to have low density due to air, so that the problem of weak shock resistance is easily caused.

In order to solve the above problem, the positioning seat, the pressing plate 5 and the opposite pulling component 6 are accommodated in a rectangular cavity surrounded by the shaping plate 4.

The template further comprises: the cover fishplate bar 7, its unsettled setting to the outside of locating plate 4 is located to the cover, and it is spacing in order to guarantee the side direction of locating plate 4 to have two cover fishplate bars 7 at least, also can set up the butt rod 8 on the co-altitude not guaranteeing spacing, in order to strengthen the vibration effect, should cup joint the board 7 and unsettled through the support frame, also can hang up unsettledly through lifting device, also can set up to realize unsettled subaerial having the hole offering.

And one end of the abutting rod 8 is connected with the sleeve plate 7, the other end of the abutting rod 8 abuts against one side, far away from the rectangular cavity, of the shaping plate 4, and the abutting rod 8 is connected with the sleeve plate 7.

One end of the elastic element 9 is abutted against the sleeve plate 7, and the other end is abutted against one end of the abutting rod 8 close to the shape-fixing plate 4.

And the rack 10 is arranged on one side of the shaping plate 4 far away from the rectangular cavity and is abutted with the abutting rod 8.

When concrete is poured into the rectangular cavity, the shaping plate 4 is displaced along the extending direction of the shaping plate 4 by the gravity of the concrete against the abutting force of the abutting rod 8 and the rack 10, and in the process, the abutting rod 8 applies intermittent acting force to the side wall of the shaping plate 4 under the guiding action of the rack 10 and the elastic action of the elastic piece 9, so that the shaping plate 4 vibrates.

The working principle is as follows: in the process of downward displacement of the shaping plate 4, the abutting rod 8 repeatedly performs the actions of abutting with the tooth part of the rack 10 and separating from the tooth part, after the abutting rod 8 is separated from the tooth part of the rack 10, the elastic force of the elastic piece 9 pushes the abutting rod 8 to the shaping plate 4, so that the abutting rod 8 is abutted with the shaping plate 4 again, and in the process of abutting again, the abutting rod 8 converts the elastic force of the elastic piece 9 into impact force on the shaping plate 4, so that the shaping plate 4 vibrates.

In this embodiment, the side surface of the shaping plate 4 is further provided with a sliding rail or a sliding groove arranged parallel to the rack, and the hitching plate is further provided with a sliding block slidably connected with the sliding rail or a projection slidably connected with the sliding groove, so that the shaping plate 4 can be displaced along the extending direction of the rack 10.

Through the separated structure of the socket plate 7 and the setting plate 4, the setting plate 4 and the socket plate 7 can be relatively displaced, when no concrete is poured in the rectangular cavity, the relative positions of the setting plate 4 and the socket plate 7 can be fixed by utilizing the butting of the butting rod 8 and the rack 10, when the concrete is poured, the setting plate 4 can be subjected to gravity by utilizing the gravity of the concrete, the setting plate 4 is displaced along the extending direction of the setting plate 4, in the displacement process, the elastic force of the elastic element 9 is converted into the impact force on the setting plate 4 by utilizing the butting rod 8, the setting plate 4 is vibrated, the concrete can be poured, and the air in the concrete close to the setting plate 4 is reduced by the vibration of the setting plate 4, so that the density of the concrete is increased, and the shock resistance of the concrete is improved.

In a further embodiment of the second aspect, when the distance between the rack 10 and the abutting rod 8 is not changed, and when the gravity of the concrete exceeds a predetermined value, the gravity applied to the shape-defining plate 4 can always overcome the acting force between the abutting rod 8 and the rack 10, so that the shape-defining plate 4 directly slides to the bottom due to the gravity, which causes the shape-defining plate 4 to be unable to vibrate during the subsequent concrete pouring, resulting in a problem that air in the subsequent concrete pouring cannot be exhausted.

In order to solve the above problem, the graduation lines of the racks 10 are at a predetermined angle to the side wall of the setting plate 4.

The distance from the top end of the graduation line of the rack 10 to the side wall of the shaping plate 4 is greater than the distance from the bottom end of the graduation line to the side wall of the shaping plate 4.

Through making the graduation line of rack 10 and 4 lateral walls of boarding have predetermined contained angles, can be at the in-process of boarding 4 displacement, change the interval of rack 10 and butt pole 8 gradually, adjust the effort between butt pole 8 and the rack 10 for boarding 4 is the decline of tooth one by one, boarding 4 also can produce the vibration when making the concrete of follow-up pouring, discharges the air in the concrete of follow-up pouring.

In a further embodiment of the second aspect, when the tooth profile of the rack 10 is arc-shaped, there is a problem that the distance of the tooth after the abutment rod 8 is separated from the tooth of the rack 10 is too small, resulting in less vibration of the shape plate 4.

In order to solve the above problem, the tooth portion of the rack bar 10 is a ratchet-like structure.

Through the cliff type tooth part with the ratchet-shaped structure, the distance from the abutting rod 8 to the tooth part after the tooth part is separated from the rack 10 can be increased, and the vibration strength of the shaping plate 4 is increased.
