Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Next, a rail support assembly 100 according to an embodiment of the first aspect of the present invention is described.

As shown in fig. 1 and 2, the rail support assembly 100 according to the embodiment of the first aspect of the present invention may include a prefabricated cap 1 and a prefabricated pier 2. Wherein, prefabricated cushion cap 1 includes heavy chamber 11 and fourth of the twelve earthly branches portion 12, and the top of heavy chamber 11 is opened, and fourth of the twelve earthly branches portion 12 includes fourth of the twelve earthly branches chamber 121 and fourth of the twelve earthly branches piece 122, and fourth of the twelve earthly branches chamber 121 and heavy chamber 11 intercommunication are maked, and fourth of the twelve earthly branches piece 122 is located the top of fourth of the twelve earthly branches chamber 121.

As shown in fig. 1, prefabricated pier stud 2 includes pier stud 21 and tenon portion 22, and tenon portion 22 links to each other with pier stud 21, and prefabricated pier stud 2 is suitable for the pre-assembly in heavy chamber 11 and for the motion of fourth of the twelve earthly branches portion to make at least part of tenon portion 22 pass through heavy chamber 11 and get into fourth of the twelve earthly branches chamber 121 and the backstop is in the below of fourth of the twelve earthly branches piece 122, in order to realize the tenon fourth of the twelve earthly branches cooperation of tenon portion 22 and fourth of the twelve earthly branches portion 12. For example, with reference to fig. 3, during assembly, prefabricated pier 2 is pre-assembled in caisson 11, and during movement (e.g., rotation or movement) of prefabricated pier 2, at least a portion (i.e., a portion or all) of tenon 22 enters mortise 121 through caisson 11 and stops under mortise block 122, so as to achieve mortise-and-tenon engagement between tenon 22 and mortise 12 (e.g., the state shown in fig. 4 and 5).

That is to say, when assembling prefabricated cushion cap 1 and prefabricated pier stud 2, earlier sink prefabricated pier stud 2 in heavy chamber 11, then through prefabricated pier stud 2 motion of drive (for example rotate or remove), make in at least part of tenon portion 22 passes through heavy chamber 11 gets into fourth of twelve earthly branches chamber 121, because the top in fourth of twelve earthly branches chamber 121 has fourth of twelve earthly branches piece 122, thereby tenon portion 22 can receive the backstop of fourth of twelve earthly branches piece 122 and can not upward move, in order to avoid tenon portion 22 upwards deviate from fourth of twelve earthly branches chamber 121, so far tenon fourth of twelve earthly branches cooperation of tenon portion 22 and fourth of twelve earthly branches portion 12 targets in place, prefabricated pier stud 2 and prefabricated cushion cap 1 between tenon fourth of twelve earthly branches are connected. It can be understood that, when the mortise and tenon joints of the tenon part 22 and the mortise part 12 are matched in place, although the mortise block 122 is stopped above the tenon part 22, a gap (i.e. no contact) may be formed between the bottom surface of the mortise block 122 and the top surface of the tenon part 22, so that the tenon part 22 can smoothly enter the mortise cavity 121.

Therefore, according to the track support assembly 100 provided by the embodiment of the invention, the prefabricated bearing platform 1 and the prefabricated pier stud 2 can be factory prefabricated components, and the prefabricated bearing platform 1 and the prefabricated pier stud 2 can be assembled in a mortise-tenon matching manner, so that the field construction time is greatly shortened, and the overall structural strength of the track support assembly 100 is improved.

In some embodiments of the present invention, as shown in fig. 1 and 4, the track support assembly 100 may further include: and the limiting block 3 is arranged in the vacant space (shown in a combined figure 4) of the sinking chamber 11 for limiting after the tenon part 22 and the 12-mortise-tenon joint of the mortise part are matched in place. That is to say, after

tenon

22 and 12 tenon fourth of twelve earthly branches of fourth of twelve earthly branches portion cooperate, promptly the aforesaid of tenon 22 part leaves heavy chamber 11 at least and gets into fourth of twelve earthly branches chamber 121 after, the interior tendency of heavy chamber 11 must have vacant space, can utilize stopper 3 to fill the vacant space in the heavy chamber 11 this moment (nevertheless do not require to fill up, certainly, fill up also can) to play limiting displacement to prefabricated pier stud 2, avoid prefabricated pier stud 2 to remove and cause tenon 22 and fourth of twelve earthly branches portion 12 to break away from the cooperation. Therefore, the limiting block 3 can be a factory prefabricated member, and the site construction time is further shortened. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the track support assembly 100 may not include the limiting block 3, and at this time, the vacant space in the caisson 11 may be filled up by grouting or the like.

In some embodiments of the present invention, as shown in fig. 5, the track support assembly 100 may further comprise: filling part 5, filling part 5 fills prefabricated cushion cap 1, prefabricated pier stud 2 and stopper 3's fit clearance. That is, after the completion of the mortise and tenon joint fitting of the tenon part 22 and the mortise part 12 and after the completion of the filling of the stopper 3, the pressure grouting operation may be performed so that the gap space which is not filled forms the filling part 5, so that the connection reliability of the prefabricated pile cap 1 and the prefabricated pier stud 2 may be further improved, thereby improving the overall structural reliability of the rail supporting assembly 100. For example, in some specific examples, the filling portion 5 may be formed by pressure grouting to facilitate processing, but the present invention is not limited thereto, and filling may also be achieved by other manners, which will not be described herein.

In some embodiments of the present invention, as shown in fig. 6, the track support assembly 100 may further include: the position locking piece 4, the position locking piece 4 locks the mortise and tenon matched mortise and tenon block 122 and the tenon part 22 along the vertical direction. It can be understood that, can be located the below of fourth of twelve earthly branches piece 122 above fourth of twelve earthly branches chamber 121 after the aforesaid at least part entering fourth of twelve earthly branches chamber 121 of tenon portion 22, at this moment, can utilize position of lock piece 4 from the top down to run through fourth of twelve earthly branches piece 122 and be located fourth of twelve earthly branches piece 122 below tenon portion 22 to the relative position of injecing fourth of twelve earthly branches portion 12 and tenon portion 22 avoids the aforesaid at least part of tenon portion 22 to withdraw from fourth of twelve earthly branches chamber 121, thereby the tenon fourth of twelve earthly branches cooperation reliability of prefabricated cushion cap 1 and prefabricated pier stud 2 has been improved, and other construction work of convenience follow-up reliably goes on.

In some embodiments of the present invention, tongue 22 is rigidly attached to pier 21, i.e., tongue 22 is stationary relative to pier 21, and prefabricated pier 2 is a factory prefabricated component rather than a cast-in-place component at the construction site. From this, on the one hand make things convenient for prefabricated processing of prefabricated pier stud 2, on the other hand when drive pier stud 21 moves, tenon portion 22 can follow pier stud 21 motion reliably, improves the reliability of assembly. For example, in some embodiments of the present invention, several tenon portions 22 may be cantilevered at the lower end of the pier stud 21 along the main force-receiving direction, and the longitudinal ribs of the pier stud 21 are horizontally bent to form the force-receiving main ribs of the tenon portions 22 or the longitudinal ribs of the tenon portions 22 are anchored into the pier stud 21. For example, in some embodiments of the present invention, the pillar 21 and the tenon 22 may be integrally formed, thereby further improving the reliability of the assembly.

Of course, the present invention is not limited thereto, for example, in other embodiments of the present invention, the tenon portion 22 and the abutment 21 may be movably connected, for example, the tenon portion 22 may be rotatably and/or movably connected to the abutment 21, etc., so that the relative positions of the tenon portion 22 and the abutment 21 may be adjusted during the assembling process, thereby meeting the assembling requirements of the prefabricated pile 1 with different structural shapes.

In some embodiments of the present invention, as shown in fig. 5, the bottom surfaces of tenon portion 22 and pier stud 21 may be flush and all horizontal, and the bottom wall of caisson 11 and the bottom wall of mortise cavity 121 are flush and all horizontal. Therefore, the processing and the manufacturing are convenient, and the tenon part 22 can easily enter the mortise cavity 121 from the sinking cavity 11 during the assembly, so that the assembly difficulty is reduced, and the assembly efficiency is improved.

Of course, the invention is not limited thereto, and in other embodiments of the invention, for example, as shown in fig. 7, the bottom surface of tenon portion 22 and the bottom surface of pier stud 21 may not be flush, and the bottom wall of caisson 11 and the bottom wall of mortise cavity 121 may not be flush. In addition, it should be noted that when the tenon 22 is movably connected to the pillar 21, "the bottom surface of the tenon 22 is flush with the bottom surface of the pillar 21" means: at least one time the tongue 22 moves relative to the abutment 21, the bottom surface of the tongue 22 is flush with the bottom surface of the abutment 21.

Here, it should be noted that there are many ways to make the above-mentioned at least part (i.e. a part or all) of tenon portion 22 enter mortise cavity 121, for example, tenon portion 22 can be engaged with mortise portion 12 by driving prefabricated pier 2 to translate (for example, the following embodiment one); for another example, the tenon 22 can be engaged with the mortise 12 by driving the prefabricated pier 2 to rotate (for example, the following example two); for another example, the tenon part 22 and the mortise part 12 can be matched in a manner of driving the prefabricated pier stud 2 to move along a curve; for another example, the tenon portion 22 may be engaged with the mortise portion 12 by driving the prefabricated pier stud 2 to translate and then rotate (or rotate and then translate), and so on.

For simplicity of description, the following description is given by taking only two specific embodiments as examples, and it is obvious that other driving schemes can be understood by those skilled in the art after reading the following technical schemes, so that further description is not given.

Example one

In the first embodiment, the prefabricated pier stud is translated relative to the mortise part, so that at least part of the tenon part 22 is moved into the mortise cavity 121 through the sinking cavity 11 and stopped below the mortise block 122, so as to realize the mortise-tenon joint matching between the tenon part 22 and the mortise part 12. For example, as shown in fig. 1 and 3, prefabricated pier stud 2 is configured such that during translation of pier stud 21, at least a portion of tenon portion 22 is translated into mortise cavity 121 through countersunk cavity 11 and stops below mortise block 122, so as to achieve mortise-tenon engagement of tenon portion 22 and mortise portion 12. It can be understood that, prefabricated pier stud 2 translation's in-process, pier stud 21 and tenon portion 22 are the translation in step, consequently, prefabricated pier stud 2 constructs to drive above-mentioned at least partial translation of tenon portion 22 into fourth of twelve earthly branches chamber 121 through pier stud 21's translation, or, through the translation of drive pier stud 21, can make pier stud 21 drive tenon portion 22 translation, and the in-process of tenon portion 22 translation can be followed heavy chamber 11 and got into fourth of twelve earthly branches chamber 121. Therefore, assembly can be simply and effectively realized, the assembly difficulty is reduced, and the assembly efficiency is improved.

In the first embodiment, as shown in fig. 1, the sinking chamber 11 may include an upstream chamber 111 and a downstream chamber 112, the downstream chamber 112 and the mortise 12 are both disposed downstream of the upstream chamber 111 (as shown in fig. 1, the front side is downstream and the rear side is upstream) in the direction of translation of the pier 21 from the sinking chamber 11 to the mortise 121 (as shown in fig. 1, the rear direction is from the rear), the prefabricated pier is translated relative to the mortise, so that part of the pier 21 is translated from the upstream chamber 111 into the downstream chamber 112, and at least part of the tenon 22 is translated from the upstream chamber 111 into the mortise 121. For example, with reference to fig. 3-4, a pre-fabricated abutment 2 is pre-assembled to upstream cavity 111, and during translation of pre-fabricated abutment 2, a portion of abutment 21 (i.e., at least a portion of the lower end) is translated from upstream cavity 111 into downstream cavity 112, and at least a portion (i.e., a portion or all) of dovetail 22 is translated from upstream cavity 111 into mortise cavity 121. From this, can realize prefabricated pier stud 2's miniaturization, convenient processing and transportation, convenient assembly moreover.

Of course, the present invention is not limited thereto, and in other specific examples of the first embodiment, for example, as shown in fig. 8, the caisson 11 may not include the downstream cavity 112, for example, as shown in fig. 8, the pier 21 may be located in the upstream cavity 111 all the time during the translation process, that is, during the translation process of the pier 21 in the upstream cavity 111, the at least part of the tenon 22 may be translated into the mortise cavity 121 from the upstream cavity 111. Thereby, different practical requirements can be met.

In the first embodiment, as shown in fig. 1, there may be two mortise parts 12, and in the first direction, the two mortise parts 12 are respectively located at two sides of the downstream cavity 112, wherein the first direction is perpendicular to the direction in which the pier 21 translates and perpendicular to the vertical direction (for example, the left-right direction shown in fig. 1). From this, through increasing the quantity of fourth of twelve earthly branches portion 12, can improve the assembly flexibility ratio, for example, when pier stud 21's left side or right side have tenon portion 22, all can realize fourth of twelve earthly branches portion 12 and tenon portion 22's tenon fourth of twelve earthly branches cooperation.

Moreover, in this example, as shown in fig. 1, the tenon portions 22 may also be two and located at two sides of the pier stud 21, and the two tenon portions 22 and the two mortise portions 12 may be respectively matched with a tenon and mortise, for example, when the left tenon portion 22 may be matched with the left mortise portion 12, and the right tenon portion 22 may be matched with the right mortise portion 12, the number of the tenon portions 22 and the mortise portions 12 in the tenon and mortise matching may be increased, so that the reliability of the tenon and mortise matching between the prefabricated pile 1 and the prefabricated pier stud 2 may be increased, and the reliability of the overall structure of the rail support assembly 100 may be increased.

In some specific examples, as shown in fig. 1-2, the two tenon portions 22 have the same structure and the prefabricated pier stud 2 has a central symmetrical structure, and the two mortise portions 12 have the same structure and are arranged axially symmetrically with respect to the center line L of the downstream cavity 112. From this, convenient processing and manufacturing, moreover, prefabricated pier stud 2 can be central symmetrical structure to can adjust prefabricated pier stud 2 to the assembly orientation fast, and then reduced the assembly degree of difficulty, improved assembly efficiency. The fool-proof effect is achieved, and the prefabricated pier stud 2 can be assembled without reverse and forward assembling.

Of course, the invention is not limited to this, for example, in other embodiments of the invention, the number of the mortise parts 12 and the relative position relationship between the mortise parts 12 and the downstream cavity 112 may also be selected according to actual requirements, for example, in the example shown in fig. 9, the mortise parts 12 may also be only one and located on one side of the downstream cavity 112.

As shown in fig. 1, defining the direction in which the abutment 21 translates from the upstream cavity 111 to the downstream cavity 112 as a rear-to-front direction, the front surface of the tongue 22 may be flush with the front surface of the abutment 21 and the rear surface of the tongue 22 may be flush with the rear surface of the abutment 21. From this, pier stud 21's simple structure, the processing of being convenient for, and can further realize prefabricated pier stud 2's miniaturization, convenient processing and transportation, convenient assembly moreover, and after pier stud 21 translation, great gap can not appear in tenon fourth of twelve earthly branches cooperation department to can improve tenon fourth of twelve earthly branches complex reliability on the one hand, on the other hand can reduce the grouting material and the air-drying time of follow-up pressure caulking and use.

In addition, as shown in fig. 1, the simple structure of the pier stud 21 can be a square stud (i.e. the cross section of the pier stud 21 is rectangular), and the simple structure of the tenon part 22 can be a square block (i.e. the cross section of the tenon part 22 is rectangular), so that the processing and the assembly are convenient, and after the pier stud 21 is translated, a large gap does not occur in the tenon-and-mortise matching part, so that the reliability of the tenon-and-mortise matching can be improved on one hand, and on the other hand, the grouting material for subsequent pressure caulking can be reduced and the air drying time can be shortened.

Further, defining the direction perpendicular to the front-rear direction as the left-right direction, the front surface and the rear surface of the pier stud 21 may both extend in the left-right direction and be parallel, and the front surface and the rear surface of the tenon portion 22 may both extend in the left-right direction and be parallel. The left and right surfaces of the pier stud 21 may also both extend in the front-rear direction and be parallel, and the left surface of the tenon 22 on the left side and the right surface of the tenon 22 on the right side may also both extend in the front-rear direction and be parallel.

As shown in fig. 5, the bottom surface of the pier stud 21 may be a horizontal surface, and both the top surface and the bottom surface of the tenon 22 may be horizontal surfaces. From this, pier stud 21's simple structure, the processing of being convenient for, convenient assembly, and after pier stud 21 translation, great gap can not appear in tenon fourth of twelve earthly branches cooperation department to can improve tenon fourth of twelve earthly branches complex reliability on the one hand, on the other hand can reduce the grouting material and the air-dry time of filling a crack of follow-up pressure.

As shown in fig. 1, the length of the downstream cavity 112 in the front-rear direction may be equal to or greater than the length of the pier 21 in the front-rear direction, and the length of the mortise cavity 121 in the front-rear direction may be equal to or greater than the length of the tenon 22 in the front-rear direction. Thus, tenons 22 may all translate into mortise cavities 121 and piers 21 may all translate into downstream cavities 112. Therefore, the processing and the assembly of the limiting block 3 are convenient. Of course, the present invention is not limited thereto, and the prefabricated pier stud 2 can be processed into other shapes according to the requirement, and the description is omitted here.

Of course, the present invention is not limited thereto, and in other specific examples of the embodiment, the pier stud 21 may not be a square stud (for example, as shown in fig. 8), and the tenon 22 may not be a square block (for example, as shown in fig. 8), for example, the pier stud 21 may be a circular stud, an oval stud, an irregular stud, etc., and in this case, during the design process, it is only necessary to ensure that the space of the sinking cavity 11 and the mortise cavity 121 is enough for the prefabricated pier stud 2 to translate.

In the first embodiment, as shown in fig. 3, prefabricated pier 2 can be driven to translate by a pushing mechanism 82 (e.g. a second jack 820, etc.), and the prefabricated pile cap 1 has a supporting structure 13 thereon, where the supporting structure 13 is a groove or a bracket, the pushing mechanism 82 is supported on the supporting structure 13, and the supporting structure 13 is used for supporting the pushing mechanism 82 to provide a reaction force to the pushing mechanism 82. From this, need not to utilize support piece outside prefabricated cushion cap 1 to exert reaction force to convenient construction reduces the construction degree of difficulty and construction cost.

For example, in the particular example shown in fig. 3, the support structure 13 may be a recess and formed within the caisson 11 with an open top. From this, convenient processing can also be drawn close the distance between bearing structure 13 and prefabricated pier stud 2, is favorable to pushing mechanism 82 application of force, reduces the construction degree of difficulty and construction cost. In addition, it should be noted that, in this embodiment, when the rail supporting component 100 includes the limiting block 3, the limiting block 3 may be further configured to be an irregular structure capable of filling the grooves together, so as to further increase the construction speed and improve the reliability of the overall structure of the rail supporting component 100.

Next, an assembling method of the rail support assembly 100 of the first embodiment described above is described.

As shown in fig. 3, the assembly method may include the steps of: descending the prefabricated pier stud 2 to enable the prefabricated pier stud 2 to sink into the sinking cavity 11 (namely, hoisting the prefabricated pier stud 2 into the initial position of the preformed hole of the prefabricated bearing platform 1); the prefabricated pier stud 2 is pushed to translate, so that the tenon part 22 translates towards the mortise cavity 121 until the tenon part 22 and the 12 mortise and tenon joint of the mortise part are matched in place (namely, the prefabricated pier stud 2 is moved to a design position in a horizontal pushing mode). Then, the space of the caisson 11 is filled with the stopper 3 (i.e., the stopper 3 is then lifted and filled at the initial position). Therefore, the assembly precision requirement is low, the assembly method is simple, and the construction speed is high.

In addition, after the tenon-and-mortise work of the tenon part 22 and the mortise part 12 is matched in place, the first pressure grouting joint filling can be performed, and after the limiting block 3 is filled into the vacant space of the sinking chamber 11, the second pressure grouting joint filling can be performed, so that the matching gap among the prefabricated bearing platform 1, the prefabricated pier stud 2 and the limiting block 3 forms the filling part 5 (namely, after the limiting block 3 is in place, the matching gap among the prefabricated pier stud 2, the prefabricated bearing platform 1 and the limiting block 3 is sealed by pressure grouting).

From this, when carrying out the first pressure slip casting and filling joints, owing to not yet fill stopper 3 to have the observation space, be favorable to observing the effect that the first pressure slip casting was filled joints, can be in the upstream chamber 111 of heavy chamber 11 (be the initial position that prefabricated pier stud 2 was located) observe the quality of filling joints that the first pressure slip casting was filled joints, ensure that the gap is filled firmly by the pressure grouting material, improve track supporting component 100's structural strength.

Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the step of first pressure-grouting for caulking may also be omitted, that is, there may be only the step of second pressure-grouting for caulking. Alternatively, the steps of first pressure grouting and second pressure grouting can be omitted.

Referring to fig. 3, the assembling method may further include the steps of: before pushing the prefabricated pier stud 2 to translate (i.e. after hoisting the prefabricated pier stud 2 into the initial position of the prefabricated bearing platform 1 in the reserved hole), the beam support 6 is installed on the pier stud 21 (i.e. the reusable bracket for installation, for example, the beam support 6 can be connected to the reserved bolt hole on the pier stud 21 by using a bolt, but not limited thereto).

Then, the beam 7 with the guide wheels 71 is installed (for example, bolted) on the beam support 6, and the guide wheels 71 on the beam 7 are located at the high hole position relative to the beam 7, and then, a first jack 81 is arranged between the cross beam 7 and the upper surface of the prefabricated bearing platform 1, the cross beam 7 is supported by the first jack 81 to lift the prefabricated pier stud 2 (namely, the cross beam 7 for installation is lifted by the first jack 81 to lift the prefabricated pier stud 2 to the designed elevation), and then, the mounting height of the guide wheel 71 on the cross beam 7 can be adjusted to be lower, so that the guide wheel 71 on the cross beam 7 is lowered to a low hole position relative to the cross beam 7, the prefabricated pier 2 is lowered by the first jack 81 (i.e., the first jack 81 releases the pressure and returns the oil) until the guide wheel 71 is supported on the upper surface of the prefabricated platform 1 (i.e., the bottom of the guide wheel 71 contacts the top surface of the prefabricated platform 1 and is forced to support the weight of the prefabricated pier 2).

Then, the prefabricated pier 2 is pushed to translate by using the second jack 820. Here, it should be noted that if there is a firm horizontal counterforce device on site, the device and the second jack 820 may be directly used to push the prefabricated pier 2 to the design position of mortise-tenon joint; if there is no firm horizontal counterforce device on site, the supporting structure 13 may be provided (for example, the supporting structure 13 may be a groove structure left by widening about 100mm along the translation direction of the prefabricated pier stud 2, and the groove structure is suitable for accommodating an ultra-thin jack for pushing, i.e. the second jack 820), the second jack 820 is installed on the supporting structure 13, and the second jack 820 pushes the prefabricated pier stud 2 to translate by using the counterforce provided by the supporting structure 13 (i.e. the counterforce provided by the prefabricated pile 1).

After the grouting material for the first pressure grouting joint filling is solidified to reach the designed strength, the beam support 6 and the beam 7 for installation can be detached, and the hoisting device for hoisting is removed (of course, the hoisting device can be removed earlier, for example, after the first jack 81 is supported, the hoisting device can be selected to be removed). In addition, if the load is great, can add above-mentioned position of locking piece 4 to increase the rigidity of being connected between prefabricated cushion cap 1 and the prefabricated pier stud 2.

Therefore, compared with the wet joint connection in the related art, the rail support assembly 100 according to the embodiment of the invention basically realizes dry joint connection, has a simple construction process and a small amount of gap filling materials in the filling part, can form strength and recover traffic within 6 hours (namely the total time consumption of the whole process of the assembly method of the rail support assembly 100 can be less than 6 hours) by adopting the early-strength high-performance grouting material, improves the construction speed, avoids the defects of long-term traffic occupation caused by a long maintenance period of the traditional wet joint process, large weather influence, large noise, unstable quality and the like of cast-in-place concrete, and improves the environment protection level.

In addition, because prefabricated cushion cap 1 and prefabricated pier stud 2 all can be the mill prefab, realized the full assembled of whole structural system, the industrialization degree is high, and component production quality is controllable, reliable, and can make full use of concrete material's compressive strength, the bending and pulling strength of prefabricated cushion cap 1 and prefabricated pier stud 2 self has fully been given play to, and structural material's bearing capacity can fully embody.

That is to say, when assembling prefabricated cushion cap 1 and prefabricated pier stud 2, earlier sink into heavy intracavity 11 prefabricated pier stud 2, then rotate through prefabricated pier stud 2 of drive for at least part of tenon portion 22 gets into fourth of twelve earthly branches chamber 121 through heavy intracavity 11 in, because the top in fourth of twelve earthly branches chamber 121 has fourth of twelve earthly branches piece 122, thereby tenon portion 22 can receive the backstop of fourth of twelve earthly branches piece 122 and can not the upward movement, in order to avoid tenon portion 22 upwards deviate from fourth of twelve earthly branches chamber 121, so far tenon portion 22 and the cooperation of fourth of twelve earthly branches portion 12 target in place, tenon fourth of twelve earthly branches connection between prefabricated pier stud 2 and the prefabricated cushion cap 1.

It should be noted that, during the rotation of prefabricated pier stud 2, pier stud 21 and tenon 22 rotate synchronously around the same pivot axis (for example, the central axis of pier stud 21), so that when pier stud 21 is driven to rotate, pier stud 21 drives tenon 22 to rotate synchronously, so that at least part of tenon 22 is rotated into mortise cavity 121. Therefore, assembly can be simply and effectively realized, the assembly difficulty is reduced, and the assembly efficiency is improved.

In this embodiment, as shown in fig. 10-11, caisson 11 may include central cavity 113 and peripheral cavity 114, where peripheral cavity 114 and mortise element 12 are both disposed around central cavity 113, pier stud 21 fits within central cavity 113 and rotates about a pivot axis passing vertically through pier stud 21, and tenon 22 rotates from peripheral cavity 114 into mortise cavity 121 and stops below mortise block 122. From this, can reduce the motion space of prefabricated pier stud 2 for the size of heavy chamber 11 can be less, and the follow-up operation of filling of being convenient for has shortened the engineering time. Of course, the invention is not limited thereto, and in other specific examples of the first embodiment, the caisson 11 may also be configured in other shapes, and the pivot axis of the prefabricated pier stud 2 may not extend through the pier stud 21, thereby satisfying different practical requirements.
