Description

Beam-column joint structure, beam-column joint method, and building structure

Technical Field

The present invention relates to a beam-column joint structure, a beam-column joint method, and a building structure using the beam-column joint structure.

Background

The rapid construction of high quality buildings has long been a sought goal of the construction and construction industry. Among the construction methods, the precasting construction method has been successfully applied to various buildings and construction projects due to the advantages of excellent quality, safe and rapid construction, economic and reasonable construction cost, and the like. The precasting method is a structural device for rapidly producing high-precision and high-quality uniform columns, beams, plates and the like in large quantities by manufacturing a reinforcement structure such as a reinforcement cage, constructing a template and pouring concrete on the periphery of a precasting plant or a construction site through a standardized operation flow and a modularized mold. Subsequently, the produced structural body is assembled on the construction site by precise handling management and assembly work in the construction site. Therefore, the workload in the construction site can be reduced to the minimum, the manpower and the construction time are reduced, and the construction period is shortened. In addition, the construction method can reduce or avoid scaffold construction, and greatly improves the construction safety.

The conventional precasting method is to construct a structure upward in a layer-by-layer manner, and thus the construction speed is limited. In view of the above, it is expected in the industry that a structure can be constructed in multiple layers and cross beams can be arranged between each floor to further increase the construction speed.

The column structure 21 of the precast beam column structure 2 includes a main bead assembly 211 and a stirrup assembly 212 fixed to the main bead assembly 211. The stirrup assembly 212 is a helical stirrup assembly and includes a primary helical stirrup 2121 and a plurality of secondary helical stirrups 2122. The plurality of sub-helical stirrups 2122 are arranged substantially outside the main helical stirrup 2121 and partially penetrate into the main helical stirrup 2121, i.e., each of the plurality of sub-helical stirrups 2122 overlaps the main helical stirrup 2121. In the embodiment, the four corners of the outer side of the main helical stirrup 2121 are provided with the auxiliary helical stirrups 2122, the arrangement positions and the number of the auxiliary helical stirrups 2122 can be adjusted according to actual requirements, and the main bar element 211 is provided with a plurality of main bars penetrating into each auxiliary helical stirrup 2122. In this embodiment, the main-rib assembly 211 has three main ribs penetrating each secondary helical stirrup 2122 and located outside the main helical stirrup 2121. The number of main bars in each secondary helical stirrup 2122 of the main bar assembly 211 can be adjusted according to actual needs.

As shown in fig. 1C, the beam structure 22 of the precast beam-column structure 2 has a plurality of beam ribs 224 that traverse the length of the column structure 21 of the entire precast beam-column structure 2 and extend to protrude from the free end 223 of the beam structure 22. In the present embodiment, two upper and lower rows of beam ribs 224 are protruded outwardly from the free end 223 of the beam structure 22 by a first distance D1, and the arrangement and number of the beam ribs 224 can be adjusted as required.

As shown in fig. 1C, the engaging member 23 is an elongated plate and has a second length L2 in the height direction. The inner end 231 of the joint member 23 has a plurality of second through holes 2311, and the main helical stirrup 2121 of the column structure 21 of the precast beam-column structure 2 passes through the plurality of second through holes 2311 of the inner end 231 of the joint member 23 to fix the joint member 23 to the column structure 21 of the precast beam-column structure 2. In the embodiment, the second through holes 2311 are substantially arranged in a straight line, and each row has 3 through holes, and the number of the second through holes can be adjusted according to the length of the engaging member 23, the pitch of the main helical stirrup 2121 and the actual requirement.

Please refer to fig. 2A. Fig. 2A is a schematic diagram of a preferred embodiment of the present invention with pillars arranged per unit area. The columns 1 are arranged at predetermined intervals (i.e., a third distance D3) along the outer periphery of a unit area a of a predetermined construction area such that the columns 1 are distributed at the corners and sides of the unit area a. The column body 1 has a plurality of reinforcing bars extending upward from a top surface 11 of the column body 1 to form a plurality of connecting bars 12 for connecting the precast beam-column structure. In this embodiment, the column body 1 may be a precast column structure or a cast-in-place concrete column body.

Please refer to fig. 2B. Fig. 2B is a schematic view of a building structure using a precast beam column structure according to a preferred embodiment of the present invention. The bottom surface 213 of the column structure 21 of the precast beam-column structure 2 has a plurality of elongated grooves 214 (shown in fig. 1A and 1B) corresponding to the plurality of connection ribs 12 protruding from the top surface 11 of the column body 1 disposed on the predetermined area a (shown in fig. 2A), so that the elongated grooves 214 of the bottom surface 213 of the column structure 21 of the precast beam-column structure 2 are fitted to the connection ribs 12 protruding from the top surface 11 of the column body 1 when the precast beam-column structure 2 is mounted on the column body 1. The length of the beam structure 22 due to the precast beam-column structure 2 is approximately half the length of the predetermined interval (i.e., the third distance D3). In the present embodiment, the total length of the first distance D1 and the second distance D2 of the beam structure 22 of the precast beam-column structure 2 is approximately half of the length of the third distance D3, and when the precast beam-column structure 2 is installed on the column body 1, the beam structure 22 of the precast beam-column structure 2 and the beam structure of another precast beam-column structure 2 at an adjacent position are aligned and abut each other. In other embodiments of the present invention, the bottom surface 213 of the column structure 21 of the precast beam-column structure 2 may be protruded with a connecting rib, and the top surface 11 of the column body 1 may be provided with a corresponding elongated slot to connect the precast beam-column structure 2 with the column body 1.

As shown in fig. 2B, the constructor moves the reinforcing bar coupler 225 sleeved on the beam rib 224 of the beam structure 22 of the precast beam-column structure 2, so that two ends of the reinforcing bar coupler 225 are respectively coupled to the corresponding beam ribs 224 of the beam structure 22 of the precast beam-column structure 2 at adjacent positions, and then moves the hoop 226 sleeved on the periphery of the beam rib 224, so that the hoop is sleeved and fixed on the beam rib 224 at predetermined intervals to connect the precast beam-column structures 2 at adjacent positions.

Please refer to fig. 3. Fig. 3 is a schematic view of a cross beam of a preferred embodiment of the present invention. The beam 3 is a reinforced concrete structure or a precast reinforced concrete structure which is cast on site. The end 31 of the cross member 3 has a groove 32 corresponding to the shape of the engagement member 23 (as shown in fig. 1B or fig. 4A). The channel 32 extends upwardly from the bottom surface 33 of the end 31 of the beam 3 by a first length L1, wherein the first length L1 is less than the height T of the beam 3. The top surface 34 of the end 31 of the beam 3 has a hole 35 communicating with the groove 32 for grouting. In addition, the lap bars 341 protrude from the top surface 34 of the cross member 3.

Please refer to fig. 4A-4D. Fig. 4A-4D are schematic diagrams of the bonding process of the preferred embodiment of the present invention for fixing the cross beam 3 to the precast beam column structure 2B, comprising the following steps:

step (a), as shown in fig. 4A, after the second precast beam column structure 2B is erected and positioned and connected with another precast beam column structure in an adjacent position, the cross beam 3 is hoisted to the vicinity of the joint member 23 in preparation for bonding the groove 32 of the cross beam 3 to the joint member 23 of the second precast beam column structure 2B.

Step (B), as shown in fig. 4B, the cross beam 3 is fixed to the second precast beam column structure 2B through the engagement of the groove 32 and the joint member 23. The cross beam 3 extends upwards from the bottom surface 33 of its end 31 into a groove 32 of a first length L1, the first length L1 being smaller than the height T of the cross beam, while the engaging part 23 has a second length L2 in its longitudinal direction. Since the second length L2 of the engaging member 23 is smaller than the first length L1 of the groove 32 of the beam 3, when the engaging member 23 is engaged in the groove 32 of the beam 3, the engaging member 23 can be completely engaged in the groove 32 of the beam 3, and the receiving space S is still formed in the groove 32 below the engaging member 23. In the present embodiment, after the groove 32 of the cross member 3 and the engagement member 23 are aligned in the lateral direction, the cross member 3 is moved in the vertical downward direction via hanging, and the engagement member 23 is engaged in the groove 32 of the cross member 3.

And (C) as shown in fig. 4C and 4D, the constructor forms and grouts the joint of the cross beam 3 and the second precast beam-column structure 2B. In order to fill gaps at the joint of the cross beam 3 and the second precast beam and column structure 2B, the formwork 7 is sealed at the joints of the left side, the right side and the bottom side of the joint of the cross beam 3 and the second precast beam and column structure 2B and the bottom side of the groove 32. Subsequently, the holes 35 reserved from the top surface 34 of the cross beam 3 are grouted so that concrete or cement mortar can fill the gaps at the connection between the cross beam 3 and the second precast beam column structure 2B, the gaps between the grooves 32 and the joint members 23, and the accommodation spaces S below the joint members of the grooves 32 along the holes 35. And (3) after the concrete or cement mortar is cured, removing the template 7, and finishing the beam-column joint structure of the beam 3 and the second precast beam-column structure 2B.

Referring to fig. 5A-5C, a schematic diagram of a bonding process for fixing a beam 4 of a steel skeleton structure to a precast beam-column structure 2B according to another preferred embodiment of the present invention is shown, which includes the following steps:

step (a), as shown in fig. 5A, after the second precast beam and column structure 2B is erected and positioned and connected to another precast beam and column structure (not shown) at an adjacent position, the beam 4 is hoisted to a position adjacent to the joint member 23 'to prepare for the joint member 23' for joining the beam 4 to the second precast beam and column structure 2B. In the present embodiment, the engaging member 23 'has substantially the same structure as the engaging member 23 of the previous embodiment, but a plurality of first through holes 2321' are further provided at the outer end 232 'of the engaging member 23' for connecting the cross beam 4. The plurality of first perforations 2321' are arranged vertically in a generally double-row linear arrangement. In the embodiment, each row has 4 through holes, and the number and the position distribution of the first through holes can be adjusted according to actual requirements. The cross member 4 includes an upper wing plate 41, a lower wing plate 42, and a web 43. The lower wing plate 42 is substantially parallel to the upper wing plate 41, and the upper and lower ends of the web 43 are substantially perpendicularly connected to the lower side of the upper wing plate 41 and the upper side of the lower wing plate 42. The top surface 411 of the upper wing plate 41 is provided with a plurality of shear pins 412. The end 44 of the cross beam 4 has a plurality of third through holes 441. In an embodiment of the present invention, a plurality of third perforations 441 are located in the web 43 of the cross beam 4 and are arranged generally vertically in a double row linear formulation, and correspond to the plurality of first perforations 2321' of the outer end 232' of the engagement member 23 '.

Step (B), as shown in fig. 5B and 5C, after aligning the third through holes 441 (shown in fig. 5A) of the end portion 44 of the cross beam 4 with the first through holes 2321 'of the end portion 232' of the joint member 23', the constructor passes a plurality of fasteners 5 (e.g., fixing bolts) through the first through holes 2321' of the end portion 23 'of the joint member 23' and the third through holes 441 of the end portion 44 of the cross beam 4 and then engages with corresponding nuts (not shown), thereby fixing the cross beam 4 to the second precast beam-column structure 2B.

Referring to fig. 6A and 6B, in another embodiment of the present invention, a column structure 21' of a precast beam-column structure 2' is similar to the column structure 21 of the precast beam-column structure 2 of the previous embodiment, and the main difference is that a beam structure 22' is a steel structure. In this embodiment, the precast beam column structure 2' is roughly divided into two types of a first precast beam column structure 2A ' and a second precast beam column structure 2B '. As shown in fig. 6A, at a height H1-H3 of each floor, the first precast beam-column structure 2A ' is provided with substantially orthogonal beam structures 22' on adjacent two sides of the column structure 21', forming an L-shaped structure with each other, and thus adapted to be mounted on the column body 1 at the corner of unit area a (as shown in fig. 7A). As shown in fig. 6B, at the height H1-H3 of each floor, the second precast beam-column structure 2B ' is provided with beam structures 22' at opposite sides of the column structure 21' in substantial alignment, such that the beam structures 22' on both sides of the column structure 21' form an elongated structure with each other, and are thus adapted to be mounted on the column 1 on the sides of the unit area a except at the corners (as shown in fig. 7A).

The column structure 21 'of the precast beam column structure 2' at the height H1-H3 of each floor may be provided with joint members 23 for connecting precast reinforced concrete beams 3 (shown in fig. 3). In the embodiment of the invention shown in fig. 7B, the first precast beam column structure 2A ' at the corners of the unit area a and the second precast beam column structure 2B ' at the second side E2 of the unit area a and the second precast beam column structure 2B ' at the fourth side E4 thereof are provided with the joint members 23 at the column structures 21' at the height H1-H3 of each floor for connecting the cross beams 3 at the first side E1 of the unit area a and the second precast beam column structure 2B ' at the third side E3 thereof, and the joint members 23 are not provided. In other embodiments of the present invention, whether the joint member 23 is provided on the precast beam column structure 2 'may be determined according to the position where the precast beam column structure 2' is provided. In other embodiments of the present invention, the precast beam-column structure 2 'may also be provided with a joint member 23' for connecting the beam 4 of the steel skeleton structure (see fig. 5A).

Please refer to fig. 6C and 6D. FIG. 6C is a schematic diagram of a partial internal structure of the embodiment shown in FIG. 6B. FIG. 6D is a cross-sectional schematic view of the main tendon assembly and the stirrup assembly of the column structure of the embodiment shown in FIG. 6B. The column structure 21' of the precast beam column structure 2' includes a main rib assembly 211' and a stirrup assembly 212' fixed to the main rib assembly 211 '. The stirrup assembly 212' is a helical stirrup assembly and includes a primary helical stirrup 2121' and a plurality of secondary helical stirrups 2122 '. The main helical stirrups 2121' are inserted through a plurality of fourth through holes 222' of the inner end portion 221' of the beam structure 22' on each side of the precast beam-column structure 2 '. In the present embodiment, the fourth through holes 222' are substantially aligned in a straight line. In addition, the plurality of sub-helical stirrups 2122' are disposed substantially outside the main helical stirrup 2121' and have a portion penetrating into the main helical stirrup 2121', i.e., each portion of the plurality of sub-helical stirrups 2122' overlaps the main helical stirrup 2121 '. In the embodiment, the four corners outside the main helical stirrup 2121 'have the auxiliary helical stirrups 2122', and the positions and the number of the auxiliary helical stirrups can be adjusted according to actual requirements. In addition, the main-rib assembly 211 'is inserted into the secondary helical stirrups 2122', and the main-rib assembly 211 'has a plurality of main ribs inserted into each of the secondary helical stirrups 2122'. In this embodiment, the main-rib assembly 211' has three main ribs penetrating each secondary helical stirrup 2122' and at the outer edge of the main helical stirrup 2121 '. In other embodiments of the present invention, the main-rib assembly 211' may have two main ribs in each secondary helical stirrup 2122', and the number of main ribs in each secondary helical stirrup 2122' may be adjusted according to actual requirements.

The precast beam column structure 2' is connected to the column body 1 in substantially the same manner as the precast beam column structure 2 of the previous embodiment is connected to the column body 1. As shown in fig. 6A and 6B, the bottom surface 213' of the column structure 21' of the precast beam-column structure 2' has a plurality of elongated grooves 214' corresponding to the plurality of connecting ribs 12 protruding from the top surface 11 of the column body 1 disposed on the predetermined area a (as shown in fig. 7A), so that the elongated grooves 214' of the bottom surface 213' of the column structure 21' of the precast beam-column structure 2' are fitted over the connecting ribs 12 protruding from the top surface 11 of the column body 1 when the precast beam-column structure 2' is mounted on the column body 1. As shown in fig. 7B, since the length of the beam structure 22' of the precast beam-column structure 2' is approximately half the length of the predetermined interval (i.e., the third distance D3 shown in fig. 7A), when the precast beam-column structure 2' is installed on the column body 1, the beam structure 22' of the precast beam-column structure 2' and the beam structure 22' of another precast beam-column structure 2' at an adjacent position are aligned with each other in the length direction of the beam. In other embodiments of the present invention, the bottom surface 213 'of the column structure 21' of the precast beam-column structure 2 'may be protruded with a connecting rib, and the top surface 11 of the column body 1 may be provided with a corresponding elongated slot to combine the column structure 21' with the column body 1. In addition, as shown in fig. 6A and 6B, the free end 223' of the beam structure 22' of the precast beam-column structure 2' has a plurality of connection holes 228', and in the embodiment of the present invention, the plurality of connection holes 228' are vertically arranged in a substantially double-row linear arrangement.

As shown in fig. 7B, the beam structure 22 'of the precast beam column structure 2' at the adjacent position is connected by a joint plate 24 'having a plurality of fifth through holes (positions where the fastener 6 is penetrated by the joint plate 24' in fig. 7B). The two end portions 242 'of the attachment joint plate 24' are respectively attached to the free ends 223 'of the corresponding beam structures 22' of the adjacent precast beam and column structures 2', and a plurality of fifth through holes, which are bolted into the two end portions 242' of the joint plate 24', with fasteners 6 (e.g., fixing bolts), are engaged with corresponding nuts after being engaged with the plurality of connecting holes 228' of the free ends 223 'of the corresponding beam structures 22' of the adjacent precast beam and column structures 2', so as to fixedly connect the beam structures 22' of the adjacent precast beam and column structures 2 'through the joint plate 24'.

The steps of fixing the cross beam 3 to the second precast beam column structure 2B 'having the joint member 23 after the precast beam column structure 2' is mounted in position are the same as those of the previous embodiment of fig. 4A to 4D. Otherwise, the step of fixing the cross beam 4 to the second precast beam column structure 2B 'having the joint member 23' is the same as that of the previous embodiment fig. 5A to 5C.
