Description

Technical Field

[0001] This invention relates to the technical field, specifically to a device and method for manufacturing a TRC mold shell with constrained assembly and no stirrups required for cylindrical TRC mold shells. Background Technology

[0002] New-type building industrialization is the core of the modernization of the construction industry, and the development of prefabricated RC structures is the only way to achieve new-type building industrialization.

[0003] The inherent characteristics of traditional prefabricated RC structures are, on the one hand, that the components have a large self-weight; on the other hand, because the structural components are prefabricated in the factory and then transported to the construction site for hoisting and casting, the prefabricated components have already undergone a long hardening time during the casting process, and the hydration reaction of their cementitious substrate is basically completed. Therefore, the chemical bond between them and the cementitious substrate of the later-cast part is weak, resulting in poor bonding performance between the prefabricated and later-cast parts in the structure, affecting the continuity of the structure, and consequently causing the overall structure to be inferior to that of cast-in-place structures.

[0004] Therefore, for RC (concrete reinforced concrete) prefabricated construction methods, issues such as structural integrity and transportation of prefabricated components are important factors restricting its development. Among them, the issue of structural integrity is particularly prominent, resulting in its seismic performance being inferior to that of cast-in-place structures.

[0005] The TRC-formed confined core concrete prefabricated stirrup-free cylindrical column (hereinafter referred to as "new column") uses TRC to fabricate a cylindrical formwork with only main reinforcement (no stirrups), such as... Figure 8 As shown, after the formwork is transported to the construction site and hoisted into position, core concrete is poured inside the formwork to form a "new type of column".

[0006] In the "new type of column", the precast formwork serves as both a construction template and part of the column (i.e., it is not removed after construction). At the same time, the fiber fabric mesh in the formwork replaces the stirrups in the traditional RC column to provide lateral restraint for the core concrete and main reinforcement of the column.

[0007] This type of column has the following characteristics: (1) The formwork is manufactured in the factory, with a high degree of industrialization, and the quality and precision are easily guaranteed; (2) Since the lightweight, high-strength, and corrosion-resistant fiber fabric mesh is used to replace the traditional stirrups, the self-weight of the column can be effectively reduced, and the problem of reduced mechanical performance of the column due to the corrosion of the stirrups can be avoided. At the same time, the fabric mesh can also effectively improve the crack resistance of the column and improve the durability of the structure; (3) It can save a lot of construction formwork and labor; (4) According to domestic and foreign research data, this type of structure has the same integrity and seismic performance as cast-in-place concrete components, and can overcome the shortcomings of the existing prefabricated structures in my country that are not good enough in terms of integrity and seismic performance; (5) No special construction technology is required, such as prestressing technology; (6) The formwork is relatively light, which is convenient for transportation and hoisting, and no special construction equipment is required. Summary of the Invention

To promote the widespread application of this novel column, this invention provides a TRC mold shell constrained assembly type stirrup-free cylindrical column manufacturing device and method, which can effectively solve the problem of factory production of the novel cylindrical mold shell.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a TRC mold shell constraint assembly type stirrup-free cylindrical TRC mold shell manufacturing device, comprising a support, a main cylinder, a central shaft, a fabric mesh, a pressure roller, and an outer template; the support is provided with a support base, the central shaft is provided with a detachable transmission wheel, and the two ends of the central shaft are supported on the support base and can rotate freely; the pressure roller is placed on the fabric mesh and can roll freely; the main cylinder includes a front end plate, a rear end plate, an inner template, and a main rib, the front end plate and the rear end plate are fixed to the central shaft by an outer nut and an inner nut, and the main rib is arranged between the front end plate and the rear end plate; the outer template is located outside the main rib and at a suitable distance from the main rib, and its two ends are tightly attached to the inner surfaces of the front end plate and the rear end plate.

[0010] Preferably, the inner surfaces of the front end plate and the rear end plate are provided with grooves that are adapted to the inner template, and the edges of the front end plate and the rear end plate are provided with a number of corresponding main rib grooves and a number of corresponding buckles. The main ribs are placed in the corresponding main rib grooves and locked and fixed by the buckles.

[0011] Preferably, the front end plate is further provided with a plurality of casting holes, which are located on the outside of the inner template and are evenly distributed along the circumferential direction.

[0012] Preferably, the inner template is cylindrical and includes several template blocks and a soft rubber sheet. The soft rubber sheet is pasted on the outer surface of the template blocks, and the template blocks are arranged at appropriate intervals along the circumferential direction. The two ends of the inner template are respectively inserted into the grooves of the front end plate and the rear end plate.

[0013] Preferably, the inner template is connected to the central shaft via a connecting rod and a slip ring; one end of the connecting rod is hinged to the inner template via a hinge, and the other end is hinged to the slip ring via a 90-degree hinge; the slip ring is sleeved on the central shaft and can slide freely, and when the slip ring slides to the point where the connecting rod is perpendicular to the central shaft, it is fixed by fixing nuts on both sides of the slip ring.

[0014] Preferably, the outer template includes two semi-cylindrical plates, each semi-cylindrical plate has a wing plate on its longitudinal side, and the wing plate has a number of corresponding bolt holes. The two semi-cylindrical plates are tightly fixed together by bolts passing through the bolt holes.

[0015] This invention provides a method for manufacturing a TRC (Traction Controlled Reinforcement) cylindrical TRC mold shell with constrained assembly and no stirrups, based on the aforementioned manufacturing device, comprising the following steps:

[0016] S1. Inner template installation: First, tighten the fixing nut on one side to the corresponding position at the end of the central shaft. Then, put the slip ring connected to the inner template through the connecting rod onto the central shaft. Push the slip ring on the other side. Through the cooperation of the hinge and the 90-degree hinge, make one end of the connecting rod perpendicular to the central shaft and the other end perpendicular to the inner template, so that the inner template is fully opened. Finally, tighten the fixing nut on the other side to achieve relative fixation between the inner template and the central shaft.

[0017] S2. Installation of front and rear plates: First install the inner nuts at both ends of the central shaft, then install the front and rear plates respectively. Adjust the position of the inner nuts so that the two ends of the inner template are inserted into the grooves on the inner side of the front and rear plates. Tighten the outer nuts to fix the front and rear plates. During the tightening process, rotate and adjust to make the main rib grooves of the two correspond one by one. Then install the drive wheel and install the whole assembly on the bracket so that the two ends of the central shaft are supported on the support.

[0018] S3. Main reinforcement installation: Place both ends of the main reinforcement into the corresponding main reinforcement grooves in the front and rear plates respectively, and fasten the corresponding locks to fix the main reinforcement.

[0019] S4. Fabric web winding: Fix one end of the fabric web in the fabric web roll to a main rib of the main cylinder, tighten the fabric web by the pressure roller, apply rotational force to the drive wheel, and drive the main cylinder to rotate by the central shaft to achieve fabric web winding. After winding, cut the fabric web and fix the cut end.

[0020] S5. High-performance mortar pouring: Remove the main cylinder with the wrapped fabric mesh and the central shaft from the support. Install two semi-cylindrical outer templates with wing plates on its outer perimeter. Screw bolts into the bolt holes to make the outer templates fit together tightly. Then pour high-performance mortar into the pouring holes.

[0021] S6. Demolding: After the high-performance mortar has reached the required curing period, first unscrew the bolts on the bolt holes of the outer formwork and remove the outer formwork. Then unscrew the outer nuts, remove the front and rear plates, and then unscrew the fixing nuts on one side and drag the central shaft to make the inner formwork retract and detach from the inner surface of the mortar. Finally, remove the inner formwork along with the central shaft and other components to complete the demolding.

[0022] Preferably, in step S1, the connecting rod and the inner template are connected by a hinge, and the connecting rod and the slip ring are connected by a 90-degree hinge. The slip ring is sleeved on the central axis and can slide freely. The connecting rod is rotated by sliding the slip ring, thereby controlling the opening and closing of the inner template, ensuring that the inner template remains coaxial with the central axis after it is opened.

[0023] Preferably, in step S4, the pressure roller is always placed on the fabric web and pressure is continuously applied to the fabric web during the winding process to keep it taut and ensure that the fabric web is evenly distributed on the outer periphery of the main cylinder.

[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] Example: The present invention provides a TRC formwork constraint assembly type stirrup-free cylindrical TRC formwork fabrication device, including a main body and an outer template 9.

[0040] like Figure 1 As shown, the main body includes a support 1, a main cylinder 2, a central shaft 3, a fabric roll 4, and a pressure roller 5. A support 1 (1) is placed on the support 1, and a transmission wheel 3 (1) is placed on the central shaft 3. The transmission wheel 3 (1) is threadedly connected to the central shaft 3 and is detachable. Both ends of the central shaft 3 are supported on the support 1 (1) and can rotate freely; the pressure roller 5 is placed on the fabric roll and can roll freely. A rotational force is applied to the transmission wheel 3 (1), which drives the main cylinder 2 to rotate via the central shaft 3, and the pressure roller 5 tightens the fabric roll, thus achieving the taut winding of the fabric roll 4 around the main cylinder 2.

[0041] like Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 7As shown, the main tube 2 includes a front end plate 2 (1), a rear end plate 2 (2), an inner template 2 (3), and main reinforcing bars 2 (4). The inner surfaces of the front end plate 2 (1) and the rear end plate 2 (2) are provided with grooves 2 (12) that are adapted to the inner template 2 (3). The edges of the front end plate 2 (1) and the rear end plate 2 (2) are provided with a number of corresponding main reinforcing bar grooves 2 (5) and a number of corresponding latches 2 (6). The front end plate 2 (1) is also provided with a number of casting holes 2 (7) distributed circumferentially on the outer side of the inner template 2 (3). The front end plate 2 (1) and the rear end plate 2 (2) are fixed to the central shaft 3 by outer nuts 6 and inner nuts 7. The main reinforcing bars 2 (4) are placed in the corresponding main reinforcing bar grooves 2 (5) of the front end plate 2 (1) and the rear end plate 2 (2) and locked by the corresponding latches 2 (6). The inner template 2 (3) is characterized in that it is cylindrical and includes several template blocks 2 (301) and soft rubber skin 2 (302). The soft rubber skin 2 (302) is pasted on the outer surface of several template blocks 2 (301) arranged at appropriate intervals along the circumference. The purpose of leaving appropriate intervals is to allow the inner template 2 (3) to have a certain range of expansion and contraction. The two ends of the inner template 2 (3) are respectively inserted into the grooves 2 (12) of the front end plate 2 (1) and the rear end plate 2 (2), and are connected to the central shaft 3 through the connecting rod 2 (8) and the slip ring 2 (9). One end of the connecting rod 2 (8) is connected to the inner template 2 (3) through the hinge 2 (10), and the other end is connected to the slip ring 2 (9) through the 90-degree hinge 2 (11). The slip ring 2 (9) is sleeved on the central shaft 3 and can slide freely. When the connecting rod 2 (8) slides to be perpendicular to the central shaft 3, it can be fixed by the fixing nuts 8 on both sides.

[0042] like Figure 6 and Figure 7 As shown, the outer template 9 is located outside the main reinforcement and is at a distance from the main reinforcement that is compatible with the thickness of the protective layer of the main reinforcement of the column “○” shaped mold shell. Both ends are tightly attached to the inner surfaces of the front end plate 2 (1) and the rear end plate 2 (2). It includes two semi-cylindrical plates with wing plates 9 (1) on the two longitudinal sides, and the wing plates 9 (1) have several corresponding bolt holes 9 (2) so that the two semi-cylindrical plates can be tightly joined together by bolts.

[0043] This invention provides a method for manufacturing a TRC (Traction Controlled Concrete) mold shell specifically for prefabricated, stirrup-free cylindrical columns with a TRC core, comprising the following steps:

[0044] S1. Install the inner template 2 (3). First, screw the right fixing nut 8 onto the appropriate position at the right end of the central shaft 3. Then, put the sliding rings 2 (9) on both sides that are connected to the inner template 2 (3) through the connecting rod 2 (8) onto the central shaft 3. Then push the left sliding ring 2 (9) to the right. Through the work of the hinge 2 (10) and the 90-degree hinge 2 (11), make one end of the connecting rod 2 (8) perpendicular to the central shaft 3 and the other end perpendicular to the inner template 2 (3), so that the inner template 2 (3) is fully opened. Finally, screw on the left fixing nut 8 to fix the inner template 2 (3) relative to the central shaft 3.

[0045] S2. Install the front plate 2 (1) and the rear plate 2 (2). First, install the inner nuts 7 at both ends of the central shaft 3, then install the front plate 2 (1) and the rear plate 2 (2) respectively. Adjust the position of the inner nuts 7 so that the two ends of the inner template 2 (3) are inserted into the grooves 2 (12) on the inner side of the front plate 2 (1) and the rear plate 2 (2). The purpose is to prevent the mortar from leaking into the inner template 2 (3) cylinder due to the joint between the inner template 2 (3) and the front plate 2 (1) and the rear plate 2 (2) when pouring high-performance mortar in the subsequent steps. Then tighten the outer nuts 6 on both sides to fix the front plate 2 (1) and the rear plate 2 (2). During the tightening of the outer nuts 6, adjust by rotation to make the main rib grooves 2 (5) on the front plate 2 (1) and the rear plate 2 (2) correspond one by one. Then install the transmission wheel 3 (1) and finally install the whole assembly on the bracket 1 so that the two ends of the central shaft 3 are supported on the support 1 (1).

[0046] S3. Install the main reinforcement bar 2 (4). Place the two ends of the main reinforcement bar into the corresponding main reinforcement bar grooves 2 (5) on the front end plate 2 (1) and the rear end plate 2 (2) respectively, and fasten the corresponding locks 2 (6) to fix them.

[0047] S4. Winding the fabric net. One end of the fabric net in the fabric net roll 4 is bonded and fixed to a main rib 2 (4) in the main cylinder 2 with structural adhesive, and the fabric net is tightened by the pressure roller 5 placed on the fabric net. Then, a rotational force is applied to the transmission wheel 3 (1), and the main cylinder 2 is rotated through the central shaft 3 to realize the winding of the fabric net on the main cylinder 2. After the predetermined number of fabric net layers is completed, the fabric net is cut off, and the cut end is bonded and fixed to the wound fabric net with structural adhesive.

[0048] S5. Pouring high-performance mortar. The main cylinder 2 with the wrapped fabric netting, together with the central shaft 3, is removed from the support 1 and placed on the mortar vibration table. Two semi-cylindrical outer templates 9 with wing plates 9(1) on the two longitudinal sides are installed on its outer periphery. The two semi-cylindrical outer templates 9 are tightly joined by screwing bolts on the bolt holes 9(2). Then, while vibrating, high-performance mortar is poured into it through the pouring hole 2(7) to complete the pouring of high-performance mortar.

[0049] S6. Demolding. After the high-performance mortar has reached the required curing time, first unscrew all the bolts on the bolt holes 9 (2) and remove the outer formwork 9. Then unscrew the outer nuts 6 at both ends, remove the front plate 2 (1) and the rear plate 2 (2), then unscrew the left fixing nut 8 to the left and drag the central shaft 3 to the left so that the inner formwork 2 (3) is tightened and detached from the inner surface of the high-performance mortar. Finally, remove the inner formwork 2 (3) together with the central shaft 3 and other components to complete the demolding.

[0050] This application significantly improves the structural stability of TRC mold shell fabrication, ensuring accurate positioning of the inner template and firm fixing of the main reinforcement, avoiding molding deviations and displacement problems, while enhancing the overall load-bearing capacity of the mold shell; it greatly simplifies the operation process, enabling modular and convenient installation and efficient fabric mesh winding, reducing manual labor difficulty and improving production efficiency; it effectively guarantees product quality, ensuring uniform mortar filling and high density through multi-point pouring, and protecting the integrity of the molded surface during demolding, thus improving the finished product qualification rate; it also optimizes process economy, with the stirrup-free design reducing material and labor costs, and the core device being reusable and adaptable to the fabrication of different mold shell specifications, reducing long-term production investment.

[0051] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
