[0029] A bridge pillar 100 in accordance with the modalities of the present disclosure is described below with reference to Figures 1 to 14. It should be noted that a top-down direction indicated in the accompanying drawings refers to a direction of the pillar of bridge 100 during normal use. Figures 3 and 4 show a prefabrication process for the prefabricated roof beam member 21. The prefabricated roof beam member 21 is turned upside down, and an indicated top-down direction refers to to a direction of the prefabricated roof beam member 21 during normal use, and does not refer to a direction of placement in the prefabrication process.

[0030] With reference to Figures 1 and 14, the bridge pillar 100 according to the modalities of the present disclosure may include: a column of pillar 10 and a cover beam 20.

[0031] Specifically, as shown in Figures 7 and 8, the column pillar 10 can include a prefabricated column pillar member 11 and a concrete layer of column pillar 12. The prefabricated column pillar member 11 can include a prefabricated pillar column cavity 111. The prefabricated pillar column cavity 111 extends in an axial direction of the prefabricated pillar column member 11, and the concrete column pillar layer 12 can be loaded into the prefabricated column column cavity 111. As shown in Figures 4 and 14, the roof beam 20 can include a prefabricated roof beam member 21 and a concrete layer of roof beam 22 The prefabricated roof beam member 21 can include a prefabricated roof beam cavity 211, and the concrete layer of the roof beam 22 can be arranged in the prefabricated roof beam cavity 211. In addition , when the cover beam 20 is connected to the co column pillar 10, the roof beam 20 can be arranged on an upper portion of the prefabricated column pillar member 11, and the concrete layer of the roof beam 22 can be connected to the column pillar concrete layer 12 , to implement a connection between the column of column 10 and the cover beam 20.

[0032] In some related technologies, a bridge pillar structure generally uses on-site foundry construction. It is necessary that a support for pouring concrete on a beam or a work platform must be built at a construction site, a long longitudinal steel bar and a stirrup are connected and connected to a pre-buried steel bar of the support platform. glove connection way, and a crane is used to assemble a combined steel model of column column segment with manual location coordination, in which the pouring of concrete after a deviation from the model is measured within a specified range, and cure and demold to complete a first segment. A next segment of a column pillar steel bar is assembled, and the above steps are sequentially repeated until the column pillar steel bars are built at a projected elevation of the bridge pillar structure. Therefore, during on-site foundry construction, a large volume of work and a long construction time are required. In addition, pouring concrete is difficult, high risk and low efficiency. In addition, the loud noise has a great effect on the surrounding environment and on road traffic.

[0033] In some other related technologies, the assembly of the bridge pillar structure is implemented by the assembly of pre-

manufactured solids. The solid prefabricated component weighs heavily, and transportation and assembly require a large number of machines, thus increasing construction costs. In addition, a construction work platform occupied during assembly is large, road traffic is also affected and traffic organization is large. In addition, when prefabricated solid components are assembled, a grouting glove technology is generally used to connect nodes, and the seismic performance of a high intensity area needs to be verified. In addition, special grouting materials and gloves are required when using grouting glove connection technology, resulting in high construction costs and higher requirements in the assembly and positioning of the construction.

[0034] However, in the present disclosure, the prefabricated pillar column member 11 of the pillar column 10 and the prefabricated cover beam member 21 of the cover beam 20 can be assembled in place after being pre-assembled. manufactured. Optionally, the prefabrication process of the prefabricated pillar column member 11 and the prefabricated cover beam member 21 can be completed at a factory or at the construction site.

[0035] When the prefabrication process is completed in a factory, in comparison with the prefabricated solid components in related technologies, the prefabricated hollow column column member 11 and the prefabricated cover beam member 21 are relatively light in weight, thus reducing transportation and lifting costs and saving labor and material resources. In addition, procedures at a construction site can be reduced. Not only are construction times and noise pollution reduced, but the effects on the environment and road traffic are also reduced, so that the work is more efficient and orderly. When the prefabricated pillar column member 11 and the prefabricated cover beam member 21 are assembled after the prefabrication process is completed at the construction site, the requirement for a machine is relatively low and the costs of construction can also be reduced. In addition, the stability of the prefabricated pillar column member 11 and the prefabricated cover beam member 21 whose weights are relatively light is easier to be guaranteed, and the assembly accuracy is greater.

[0036] Optionally, a pillar column 10 of each bridge pillar 100 can include a prefabricated pillar column member 11 and does not need to be connected via a grouting sleeve, which helps to improve the speed and safety of construction, and each scaffold is not required to be built at the construction site, which is safer. Certainly, according to the current situation and requirements, the pillar column 10 of the bridge pillar 100 can optionally be formed by a plurality of prefabricated members of connected column columns 11. In modalities that the plurality of prefabricated members of column pillar 11 are divided, the prefabricated pillar column cavities 111 of the plurality of prefabricated pillar column members 11 may be in communication. After a plurality of prefabricated pillar column members 11, the prefabricated communicating pillar column cavities 111 can be loaded with concrete, to additionally connect and secure the plurality of prefabricated pillar column members 11, so that the connection is firmer.

[0037] In addition, as shown in Figures 4 and 14, the pillar column 10 can be provided with a connecting rib 13. When the cover beam 20 is arranged on an upper portion of the prefabricated column pillar member 11, the connecting rib 13 can extend into the prefabricated roof beam cavity 211, and the concrete roof beam layer 22 can be connected to both the column pillar concrete layer 12 and the connecting rib 13 at the same time. Therefore, the concrete layer of the roof beam 22 and the concrete layer of the column pillar 12 can be tensioned together, and a connection between the roof beam 20 and the column pillar 10 is firmer and more secure, in order to meet the stress criteria of the 100 bridge pillar, which facilitates the improvement of the seismic performance of the high intensity area.

[0038] It should be noted that, in some embodiments, during construction, the prefabricated pillar column cavity 111 may first be loaded with the column pillar concrete layer 12, the prefabricated beam member roof 21 is then arranged on the upper portion of the prefabricated column column member 11, and the prefabricated roof beam cavity 211 is subsequently loaded with the roof beam concrete layer 22, to allow the concrete cover beam layer 22 and column pillar concrete layer 12 are connected to connection rib 13 and therefore concrete pouring is more convenient and easy to operate. In some other embodiments, during construction, the prefabricated roof beam member 21 can first be disposed in the upper portion of the prefabricated pillar column member 11, and the prefabricated roof beam cavity 211 and the prefabricated column column cavity 111 are then loaded with the concrete, so that the roof beam concrete layer 22 and the column column 12 concrete layer can be poured and cured simultaneously, and a connection between the roof beam concrete layer 22 and the column pillar concrete layer 12 is firmer.

[0039] The bridge pillar 100 according to the modalities of the present disclosure includes the prefabricated column pillar member 11 and the prefabricated roof beam member 21, which can simplify the procedures at the construction site, thus improving the speed and safety of construction, and avoiding the adverse effects of a smelting process at the conventional full site in a traffic environment. In addition, the prefabricated pillar column member 11 and the prefabricated roof beam member 21 are hollow, which facilitates the reduction of transportation and lifting costs, and the connection between the column column 10 and the cover beam 20 is firm and secure.

[0040] According to some embodiments of the present disclosure, as shown in Figures 1 and 2, the prefabricated pillar column member 11 may include: a hollow concrete column 112, a column pillar reinforcement rib 113 and internal cast steel plate 114. The column reinforcement rib 113 can be pre-buried in a column wall of the concrete column 112, to increase the structural strength of the concrete column 112. As shown in Figure 2, an upper portion of the column pillar reinforcement rib 113 can extend out of the concrete column 112 to form the connecting rib 13, thereby simplifying a structure of the prefabricated column column member 11 and reducing the manufacturing process . A longer connection length of the connecting rib 13 and the prefabricated pillar column member 11 indicates a firmer and more secure connection. Optionally, according to actual requirements and situation, the concrete column 112 can be in an annular structure, a square structure, or the like, and a corresponding prefabricated column column member 11 can be formed in an annular structure, a square structure or similar.

[0041] As shown in Figures 1 and 2, the internal mold steel plate 114 can be arranged on an internal circumferential surface of the concrete column 112, so that the concrete column 112 can be formed in a hollow structure and limit the pillar column prefabricated cavity 111. In addition, the internal cast steel plate 114 can be connected to the column pillar concrete layer 12. Due to the fact that the prefabricated column pillar member 11 it is loaded with the pillar column concrete layer 12 after being prefabricated, a time interval between the pouring of the concrete column 112 and the pouring of the pillar column concrete layer 12 is relatively long. New concrete and old concrete are connected by being connected to the internal cast steel plate 114 respectively, thus improving the security of the connection. Optionally, in some specific embodiments, the inner mold steel plate 114 can be a profiled steel plate, and the profiled steel plate can self-reinforce the bonding force with the concrete, so that connections between the mold steel plate internal 114 and the concrete column 112 and the internal mold steel plate 114 and the concrete layer of column pillar 12 are firmer.

[0042] Additionally, as shown in Figure 1, the column reinforcement rib 113 can be a grid-shaped reinforcement cage. The reinforcement cage can include: a plurality of internal longitudinal ribs 1131, a plurality of external longitudinal ribs 1132 and a cross-section rib 1133.

[0043] Specifically, the plurality of internal longitudinal ribs 1131 can extend in an axial direction of the concrete column 112, and the plurality of internal longitudinal ribs 1131 can be distributed at intervals in a circumferential direction of the concrete column 112. The plurality of external longitudinal ribs 1132 can also extend in an axial direction of the concrete column 112, and the plurality of external longitudinal ribs 1132 can be distributed at intervals in the circumferential direction of the concrete column 112. In a radial direction of the concrete column 112 , the outer longitudinal rib 1132 can be located on an outer side of the inner longitudinal rib 1131, to form a double-layer cage structure, and to increase the structural strength of the prefabricated pillar column member 11 over a wider range in the radial direction of the concrete column 112. The cross connection rib 1133 can be connected to the rib external longitudinal rib 1132 and internal longitudinal rib 1131, to allow external longitudinal rib 1132 and internal longitudinal rib 1131 to be fixed in relative positions in the radial direction of the concrete column 112 and, therefore, the structure is more stable.

[0044] It should be noted that Figures 1 and 2 show a modality in which the internal longitudinal rib 1131 and the external longitudinal rib 1132 form a double layer reinforcement cage. However, in some other embodiments, in the radial direction of the concrete column 112, a multi-layer reinforcement cage can be formed through the use of three layers,

four layers or more layers of the longitudinal ribs, so that the reinforcement cage can meet different structural strength requirements. In the multi-layer reinforcement cage, two adjacent layers of the steel bars can be connected using the cross connection rib 1133, so that a structure is more stable.

[0045] In some embodiments of the present disclosure, as shown in Figures 3 and 5, the prefabricated roof beam member 21 may include: a concrete channel frame 212, an inner side plate 213 and a reinforcement rib of the roof beam 214. The concrete channel frame 212 can be connected to the prefabricated pillar column member 11 to implant a connection between the prefabricated roof beam member 21 and the prefabricated column member of the column. column 11, and the concrete channel frame 212 may include the prefabricated roof beam cavity 211, so that when the concrete channel frame 212 is connected to the prefabricated column column 11 member, the cover beam concrete layer 22 is connected to the connecting rib 13 and the column pillar concrete layer 12. Optionally, in the present disclosure, the inner side plate 213 can be a steel plate, which is easier to conform, and the adhesion of the steel plate to the con creto is better.

[0046] As shown in Figure 4, the inner side plate 213 can be arranged on a cavity side wall of the prefabricated roof beam cavity 211, and the inner side plate 213 can be connected to the concrete layer. roof beam 22 so that the concrete channel frame 212 is connected to the concrete roof beam layer 22 through the inner side plate 213, and a connection between the concrete channel frame 212 and the roof layer concrete beam 22 is safer. It can be understood that, in the present disclosure, a part of the cavity side wall of the prefabricated roof beam cavity 211 can be provided with the inner side plate 213, or an entire cavity side wall of the pre-cavity made of cover beam 211 can be provided with the inner side plate 213. In other words, the inner side plate 213 can be arranged on at least a part of the cavity side wall of the prefabricated cover beam cavity 211 .

[0047] In addition, as shown in Figure 4, the roof beam reinforcement rib 214 can be pre-buried in a lower cavity wall of the roof beam prefabricated cavity 211, and one end of the reinforcement rib roof beam 214 can extend into the prefabricated roof beam cavity 211 so that the roof beam reinforcement rib 214 can be connected to the concrete roof beam layer 22, thus increasing the connection strength of the concrete channel frame 212 and the concrete layer of roof beam 22.

[0048] The lengths, number and arrangement positions of the roof beam reinforcement ribs 214 are not particularly limited in the present disclosure. For example, in the embodiment shown in Figures 3 and 4, the roof reinforcement rib 214 can include a first reinforcement rib 2141 and a second reinforcement rib 2142. In addition, a length of the second reinforcement rib 2142 can be greater than a length of the first reinforcement rib 2141, or a length of the second reinforcement rib 2142 can be greater than twice a length of the first reinforcement rib 2141, so that the reinforcement beam reinforcement rib 214 can be connected to the concrete layer of roof beam 22 in different length ranges, thus improving structural strength.

[0049] As shown in Figure 4, the extension directions of the first reinforcement rib 2141 and the second reinforcement rib 2142 are approximately the same. On the one hand, the structure is more orderly, manufacturing or demoulding at a prefabrication stage is facilitated. On the other hand, the tension of the first reinforcement rib 2141 and the second reinforcement rib 2142 can be mutually accentuated, and the effect of improving structural strength is better. Optionally, the first reinforcement rib

2141 and the second reinforcement rib 2142 can be arranged in the same cavity wall as the prefabricated roof beam cavity 211, facilitating mold design and fabrication.

[0050] Additionally, as shown in Figure 4, there may be a plurality of first reinforcement ribs 2141. The plurality of first reinforcement ribs 2141 may be adjacent to each other in pairs to form a plurality of pairs of first reinforcement ribs, two first reinforcement ribs 2141 in each pair of first reinforcement rib are connected via a first reinforcement connection rib 215, and the first reinforcement connection rib 215 can be obliquely arranged in a vertical direction, to increase strength structural reinforcement of the first two adjacent reinforcement ribs 2141, and also to improve the connection strength of the first reinforcement ribs 2141 and the concrete layer of roof beam 22. Optionally, the first reinforcement connecting rib 215 and the first reinforcement rib 2141 can be connected in welding mode.

[0051] For example, in a specific embodiment shown in Figures 3 to 5, the plurality of first reinforcement ribs 2141 are formed in two rows distributed at intervals in a wide direction (that is, a front to back direction shown in Figure 5) of the prefabricated roof beam cavity 211, and each row includes the plurality of first reinforcement ribs 2141 distributed at intervals in a length direction (i.e., a left-to-right direction shown in Figures 4 and 5 ) of the prefabricated roof beam cavity 211. A first reinforcement rib 2141 in a row is connected to an end portion of a first adjacent reinforcement rib 2141 in the other row through the first reinforcement connection rib 215, and extension directions of the first reinforcement connection ribs 215 are all different from extension directions of the first two connected reinforcement ribs 2141.

[0052] It should be noted that Figures 3 and 4 are front views of Figure

5. Both Figure 3 and Figure 4 show two first reinforcement ribs 2141 in the pair of the first reinforcement rib to facilitate the representation of a connection structure of the pair of the first reinforcement rib and the first reinforcement connecting rib 215. Indeed, in the views of Figures 3 and 4, two first reinforcement ribs 2141 in a pair of first reinforcement ribs are arranged at intervals in a wide direction (i.e., a front-to-back direction shown in Figure 5) of the cavity prefabricated roof beam 211, and the first reinforcement rib 2141 disposed on a rear side is blocked by the first reinforcement rib 2141 disposed on a front side.

[0053] Optionally, still with reference to Figure 4, there can be a plurality of second reinforcement ribs 2142, and at least two of the second reinforcement ribs 2142 can be arranged on two horizontal sides of a middle portion of the prefabricated cavity of roof beam 211. For example, at least two second reinforcement ribs 2142 are respectively arranged in a left portion and a right portion or a front portion and a posterior portion of the prefabricated roof beam cavity 211, to increase an area of reinforcement of the second reinforcement rib 2142. Optionally, a center of the prefabricated roof beam cavity 211 is used as a vertex, and an angle formed by at least two second reinforcement ribs 2142 in a circumferential direction of the pre- made of roof beam 211 is greater than 90 degrees. In the example shown in Figure 4, two second reinforcement ribs 2142 are arranged symmetrically with respect to the center line of the prefabricated roof beam cavity 211.

[0054] In addition, the two second reinforcement ribs 2142 located on both sides of the middle portion of the prefabricated roof beam cavity 211 can be connected through a second reinforcement connection rib 216, to increase the structural strength of the second reinforcement ribs 2142 on both sides of the middle portion of the pre-cavity

made of roof beam 211 and the concrete layer of roof beam 22. In this document, the second reinforcement connection rib 216 can extend horizontally or, of course, it can extend obliquely in a horizontal direction, as long as a requirement that the second reinforcement connection rib 216 connects the two second reinforcement ribs 2142 is met. Optionally, the second reinforcement connection rib 216 and the second reinforcement rib 2142 can be welded to be connected.

[0055] It should be noted that, in the present disclosure, only the first reinforcement connection rib 215 can be provided, or only the second reinforcement connection rib 216 can be provided, or both the first reinforcement connection rib 215 as the second reinforcement connection rib 216 can be supplied at the same time. In addition, a part of the first reinforcement ribs 2141 or a part of the second reinforcement ribs 2142 can be connected to the first reinforcement connection ribs 215 or to the second reinforcement connection ribs 216, or all the first reinforcement ribs 2141 can be connected. be connected to the first reinforcement connection ribs 215, and all second reinforcement ribs 2142 can be connected to the second reinforcement connection ribs 216, which are all within the protection scope of the present disclosure.

[0056] According to an additional embodiment of the present disclosure, as shown in Figures 3 to 5, the concrete channel frame 212 can include a bottom wall 2121 and a side wall 2124. The bottom wall 2121 can include a horizontal portion 2122 and an inclined portion 2123. The horizontal portion 2122 extends in a horizontal direction, the inclined portion 2123 is arranged on an outer circumference edge of the horizontal portion 2122, and the inclined portion 2123 extends obliquely upward and outwardly in one direction vertical. In this document, "out" is a direction as opposed to horizontal portion 2122, and the "up" direction is based on a top-down orientation according to a construction stage at the prefabricated beam member location cover 21 or during normal use of bridge abutment 100. The prefabricated cover beam member 21 shown in Figures 3 and 4 is turned upside down during prefabrication.

[0057] In addition, the first reinforcement rib 2141 and the second reinforcement rib 2142 can be pre-buried separately vertically in the inclined portion 2123, to increase the structural strength of the inclined portion 2123, and it is easier to manufacture and demold.

[0058] As shown in Figure 4, a lower opening of the prefabricated roof beam cavity 211 is arranged in the horizontal portion 2122, and the connecting rib 13 of the column 10 column can extend into the prefabricated cavity of cover beam 211 through the lower opening of the prefabricated cover beam cavity 211. It should be noted that Figure 4 is a schematic diagram of placing the prefabricated cover beam member 21 in a pre- manufacturing. In Figure 4, the prefabricated roof beam member 21 is placed upside down, and “the lower opening of the prefabricated roof beam cavity 211” is also based on a top-down orientation according to with a construction stage at the location of the prefabricated roof beam member 21 or during normal use of the bridge abutment 100. Therefore, the top-to-bottom direction shown in Figures 3 and 4, refers to a top-to-bottom direction. low in a construction stage at the location of the prefabricated roof beam member 21, a model 50 base that supports the prefabricated roof beam member 21 is placed in the top-down direction in the prefabrication stage , and the direction is opposite to the top-down direction in Figures 3 and 4.

[0059] Furthermore, as shown in Figures 3 and 4, the side wall 2124 can be connected to the outer circumference edge of the inclined portion 2123. The inner side plate 213 is arranged on an inner circumferential surface of the side wall 2124. Due Since the shear stress between the concrete layer of the roof beam 22 and the side wall 2124 is higher, and a requirement for connection strength is relatively high, the inner circumferential surface of the side wall 2124 is provided with the inner side 213, so that the connection between the prefabricated roof beam member 21 and the concrete layer of roof beam 22 is more firm. Certainly, according to the actual requirements and situation, an inner wall surface of the lower wall 2121 can optionally be provided with the inner side plate 213, to additionally improve connection security.

An example in which the bridge pillar 100 is manufactured according to the modalities of the present disclosure is used below to describe the method of manufacturing the bridge pillar according to the modalities of the present disclosure in detail. It should be understood that some detailed structures of the bridge pillar 100 shown in the accompanying drawings are not intended to limit the method of manufacture in the modalities of the present disclosure, and are used only as examples.

[0083] The method of manufacturing the bridge pillar 100 according to the modalities of the present disclosure is described below with reference to Figures 1 to 14 and 16.

[0084] As shown in Figure 16, the method of fabricating the bridge pillar 100 according to the modalities of the present disclosure can include the following steps.

[0085] Step 1001. As shown in Figures 1 to 2, obtain a prefabricated pillar column member 11, and as shown in Figures 3 to 5, obtain a prefabricated cover beam member 21, in which the prefabricated pillar column member 11 includes a prefabricated pillar column cavity 111 extending in an axial direction of the prefabricated pillar column member 11, wherein the prefabricated cover beam member 21 includes a prefabricated roof beam cavity 211, and the prefabricated pillar column member 11 is provided with an upwardly extending connecting rib 13.

[0086] Step 1002. As shown in Figures 6 to 7, mount the prefabricated pillar column member 11 on a mounting surface

301.

[0087] Step 1003. As shown in Figure 8, inject concrete from an upper end opening of the prefabricated column column cavity 111 into the prefabricated column column 111 cavity to cure in order to form a concrete layer of column pillar 12.

[0088] Step 1004. As shown in Figures 9 to 13, mount the prefabricated cover beam member 21 on an upper portion of the prefabricated column pillar member 11, and extend the connecting rib 13 in the pre cavity -manufactured from roof beam 211.

[0089] Step 1005. As shown in Figure 14, inject concrete into the prefabricated roof beam cavity 211 to cure in order to form a roof beam concrete layer 22 connected to the pillar column concrete layer 12 and to the connecting rib 13.

[0090] In the present disclosure, step 1001 may or may not be carried out in the same working environment as steps 1002 to 1005. That is, in step 1001, the prefabricated pillar column member 11 and the pre- made of roof beam 21 can be manufactured at the bridge construction site, or can be transported to a construction position after being prefabricated in a factory.

[0091] When the prefabricated pillar column member 11 and the prefabricated cover beam member 21 are transported to a construction position to be assembled after being prefabricated in a factory, the processes at the construction site they can be simplified, assembly is convenient, the cost of measuring a machine is reduced, and construction speed and safety are improved. The construction work area at the construction site is smaller, thus avoiding adverse effects of the conventional smelting process at the total site on traffic and the environment. In addition, the precision of the prefabricated pillar column member 11 and the prefabricated roof beam member 21 is greater, which facilitates the improvement of the quality of the bridge pillar 100. The prefabricated member of column pillar 11 and the prefabricated cover beam member 21 are hollow, which facilitates the reduction of transport and lifting costs.

[0092] In addition, the concrete layer of the roof beam 22 is connected to the connecting rib 13 and to the concrete layer of the column of pillar 12 to implant the connection between the column of pillar 10 and the roof of beam 20. The The operating process is simple, and the connection structure between the column column 10 and the cover beam 20 is firm and secure. The column pillar concrete layer 12 and the roof beam concrete layer 22 are formed by casting. A general structure has superior stability, thus improving the quality of the foundry.

[0093] It should be noted that the aforementioned steps 1001 to 1005 mean that the manufacturing method of the bridge pillar 100 includes five steps, and a sequence of steps can be switched, without limiting the manufacturing process of the bridge pillar 100 can be carried out according to the sequence from step 1001 to step 1005. For example, loading the concrete layer of column pillar 12 in step 1003 and loading the concrete layer of roof beam 22 in step 1005 are sequentially written in two stages. In the actual manufacturing process, the column pillar concrete layer 12 and the roof beam concrete layer 22 can be separately loaded according to a sequence of steps 1003 and 1005 sequentially, or the column pillar concrete layer 12 and the concrete layer of roof beam 22 can be simultaneously loaded after step 1004.

Optionally, the prefabricated roof beam member 21 can alternatively be manufactured using a centrifugation method or a pouring method. In addition, the prefabricated pillar column member 11 and the prefabricated cover beam member 21 can be manufactured using the same method or different methods. In addition, the dumping method can be a lifting method, a self-compacting concrete method for pipe / gutter dumping, an underwater concrete dumping method, a high-level discharge vibration-free dumping method or the like.

[0095] According to some embodiments of the present disclosure, as shown in Figures 1 to 2, the method for fabricating the prefabricated pillar column member 11 may include the following steps.

[0096] Step 2001. Obtain a reinforcement cage, an inner mold steel plate 14, an outer covering steel plate 15 and a positioning mold 40, where the positioning mold 40 includes a lower model 41, a internal protective tube 42 disposed on one side of the lower model 41, and an external protective tube 43 disposed on one side of the lower model 41 and located on an external side of the internal protective tube 42.

[0097] Step 2002. Place the inner mold steel plate 14 on an inner circumferential surface of the reinforcement cage, and coat the outer cover steel plate 15 on one end of the reinforcement cage.

[0098] Step 2003. Connect one end of the reinforcement cage to the lower model 41, so that the outer protective tube 43 is located on the outer side of the outer cover steel plate 15, and the inner protective tube 42 is located on the side inner of the inner mold steel plate 14.

[0099] Step 2004. Pour the concrete and cure the concrete to form the concrete column 112, in which the reinforcement cage is buried in the concrete column 112 and the upper portion of the reinforcement cage extends out of the concrete column 112 to form the connecting rib 13. The inner mold steel plate 14 is located on the inner side of the concrete column 112, and the outer cover steel plate 15 is located on the outer side of the concrete column 112.

[00100] Step 2005. Remove the positioning template 40 to obtain the prefabricated pillar column member 11.

A internal mold steel plate 14 allows the prefabricated pillar column member 11 to be formed with the prefabricated pillar column cavity 111 to form a hollow structure, which is light and convenient to transport.

[00102] Optionally, before the concrete is poured, the pillar column lifting hook 70 projecting from the upper end surface of the prefabricated pillar column member 11 can be inserted in the upper portion of the prefabricated member column pillar 11, to help move the prefabricated pillar column member 11 by hooking the column pillar lifting hook 70. For example, the reinforcement cage can be lifted using a mobile crane, be hooked to a base 44, and the lower model 41 is attached to the base 44.

[00103] Optionally, after the concrete is poured, the mold is removed after the concrete has more than 75% resistance, finally, a plurality of cable winding ropes 61 are fixed at intervals in the circumferential direction of the prefabricated member of column column 11 and then the prefabricated column column member 11 is maintained and stored.

[00104] Additionally, as shown in Figure 1, being connected to the reinforcement cage and the lower model 41, a plurality of steel bar heads at one end of the reinforcement cage can separately travel through the steel bar holes of the lower model 41, and the threaded fastener 80 is arranged at one end extending the steel bar head to secure the reinforcement cage and ensure the horizontal stability of the prefabricated column 11 column member in a demoulding stage, one stage vertical storage and the like. The fixing structure is simple and firm. In the present document, a number of threaded fasteners 80 and steel bar heads and a length of the steel bar head extending out from the lower model 41 can be flexibly adjusted according to an actual situation. For example, in some embodiments, there may be 6 to 10 steel bar heads from the reinforcement cage running through the lower model 41, and a plurality of steel bar heads can be distributed at intervals in the circumferential direction of the reinforcement cage . A length of the steel bar head extending outwards lower model 41 is not less than 5 cm, and each steel bar head can be connected to at least two threaded fasteners 80, to make the connection more secure.

[00105] In some embodiments of the present disclosure, the method for fabricating the prefabricated pillar column member 11 may include step 3001:

[00106] Place a leak-proof member between the lower model 41 and the inner mold steel plate 14 before the concrete is poured. The leak-proof member can be made of cotton pulp, a straw rope, double-sided foam tape, sponge, or the like, to prevent the concrete from leaking from a gap between the lower model 41 and the slab internal mold steel 14 during pouring.

[00107] According to some embodiments of the present disclosure, as shown in Figure 3, the method for fabricating the prefabricated roof beam member 21 may additionally include the following steps.

[00108] Step 4001. Obtain an internal side plate 213, a model 50 base, a roof beam reinforcement rib 214, an internal model 51 and an external model 52.

[00109] Step 4002. Place the inner side plate 213, the inner model 51 and the outer model 52 on the base of model 50, so that the base of model 50, the inner side plate 213, the inner model 51 and the external model 52 cooperate to form a mold cavity used to load the concrete. The internal model 51 is located on the internal side of the external model 52 and is connected to the upper portion of the internal side plate 213.

[00110] Step 4003. Insert the cover beam reinforcement rib 214 into a model through hole of the internal model 51, where two ends of the cover beam reinforcement rib 214 separately extend out of the model through hole .

[00111] Step 4004. Inject the concrete into the mold cavity and cure the concrete to form the concrete channel frame 212, where the prefabricated roof beam cavity 211 is defined by the concrete channel frame 212, one end of the roof beam reinforcement rib 214 extends in the prefabricated roof beam cavity 211, and the inner side plate 213 is located on a cavity side wall of the prefabricated roof beam cavity 211.

[00112] Step 4005. Remove the model 50 base, the internal model 51 and the external model 52 to obtain the prefabricated cover beam member

21.

[00113] In the embodiment shown in Figure 3, the side wall 2124 of the concrete channel frame 212 extends in the vertical direction, the lower wall 2121 of the concrete channel frame 212 includes the inclined portion 2123 and the horizontal portion 2122, and a radial direction cross section of the prefabricated roof beam cavity 211 is generally rectangular. The side wall 2124 of the concrete channel frame 212 is shaped using the base of model 50, the inner side plate 213 and the external model 52, and the bottom wall 2121 of the concrete channel frame 212 is shaped by using the internal model 51. During manufacture, a position that corresponds to the outer side of the bottom wall 2121 of the concrete channel frame 212 is not provided with a model, so that the mold cavity has an upper end opening , to help load the concrete from the top end opening of the mold cavity.

[00114] Optionally, after the concrete is loaded, a roof beam lifting hook 71 can be inserted on the outside of the inclined portion 2123, to help limit a lifting rope when the prefabricated roof beam member 21 it is hoisted onto the prefabricated pillar column member 11, thereby preventing the prefabricated cover beam member 21 from falling.

[00115] Furthermore, in some embodiments of the present disclosure, the model 50 base may not only be used as an inferior mold to form the concrete channel frame 212, but it can also be configured to lift the soil and pour, so that an individual can enter the prefabricated roof beam cavity 211 to operate during the removal of the mold. For example, in an additional modality, a height H of the model 50 base can satisfy that H ≥ 800 mm and, more specifically, the height H can be 1,000 mm, 1,200 mm and the like.
