Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a UHPC double T beam forming device. Background Technology

[0002] As a precast component widely used in modern bridge engineering, the double-T beam exhibits significant advantages in terms of load-bearing capacity, structural stability, and construction efficiency due to its unique double-T cross-section design.

[0003] Currently, the production of double-T beams mainly relies on mold casting technology, which achieves high-precision molding of concrete through pre-designed molds. Specifically, the reinforcing steel skeleton is fixed inside the mold, ultra-high performance concrete (UHPC) or other types of concrete are poured, and after vibration and curing, the structural component is formed. Finally, the finished product is transferred to the designated location by hoisting equipment. This industrialized production model effectively improves the level of construction standardization and is particularly suitable for engineering scenarios with high requirements for structural performance, such as long-span bridges and multi-story parking lots. However, existing double-T beam molds generally adopt a segmented structure, consisting of side molds, end molds, bottom molds, and inner molds. After the concrete reaches the design strength, each module needs to be removed one by one by manual or mechanical means. This "segment-by-segment removal" mode is not only time-consuming, but also may be prolonged under complex weather conditions (such as high temperatures that increase the bond between the concrete and the mold), thus delaying the entire project's production cycle.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] In one embodiment of the present invention, such as Figure 1-8 As shown, a UHPC double T-beam forming apparatus is provided, including a base 10, an outer mold mechanism, and an inner mold mechanism. The base 10 has an upwardly protruding pad 11. The pad 11 has a T-shaped block 12. The base 10 has a first sealing plate assembly 13 and a second sealing plate assembly 13 at its first and last ends, respectively. The outer mold mechanism includes two symmetrically distributed outer mold assemblies 20. Each outer mold assembly 20 includes a first fixed assembly 21 and a first movable assembly 22. The first fixed assembly 21 is disposed on the base 10 and abuts against one side of the T-shaped block 12. One end of the first movable assembly 22 is rotatably connected to the first fixed assembly 21, and the other end is connected to the first fixed assembly 21 by a first control member 23, which is a support screw. One set of outer mold assemblies 20 has a forming assembly 24 for forming the top of the double T-beam 50. The inner mold mechanism includes two symmetrically distributed inner mold assemblies 30, which are slidably connected to the base 10. The inner membrane assembly 30 includes a second fixed assembly 31 and a second movable assembly 32. The second fixed assembly 31 is mounted on the base 10 and abuts against one side of the T-block 12. One end of the second movable assembly 32 is rotatably connected to the second fixed assembly 31, and the other end is connected to the second fixed assembly 31 by a second control element 33, which is a hydraulic cylinder, for controlling the movement of the second movable assembly 32. The ends of the two sets of second movable assemblies 32 abut against each other to form a planar structure. A molding cavity for casting the double T-beam 50 is formed between the outer mold mechanism, the T-block 12, the inner membrane mechanism, the first sealing plate assembly 13, and the second sealing plate assembly 13.

[0040] By setting up an outer mold mechanism, an inner mold mechanism, a first sealing plate assembly 13, and a second sealing plate assembly 13, the components work together to form a molding cavity. After the concrete reaches the design strength, the first and second sealing plate assemblies 13 at both ends are removed first, and then the molding assembly 24 is removed from the first fixed assembly 21. Subsequently, under the control of the first control component 23, the first movable assembly 22 is moved downward to separate it from the double T-beam 50. Then, the first fixed assembly 21 is pushed outward to move away from the double T-beam 50, achieving rapid demolding of the outer mold mechanism. At this time, the second movable assembly 32 is driven downward by the second control component 33 to separate it from the double T-beam 50. Then, the two sets of second fixed assemblies 31 are pushed inward to move away from the double T-beam 50, achieving rapid demolding of the inner mold mechanism. This results in a more systematic and faster demolding of the double T-beam 50, greatly reducing the demolding steps. Unlike existing molds, it does not require the removal of numerous modules one by one, significantly improving demolding efficiency and effectively shortening demolding time.

[0041] It should also be noted that the outer mold mechanism and the inner mold mechanism need to be designed as multi-section outer mold components 20 and inner mold components 30 according to the length of the double T beam 50. There can be one, two, three, etc. The number of groups needs to be designed according to the actual design requirements. When installing and dismantling the outer mold mechanism and the inner mold mechanism, a modular dismantling method is adopted. This method can greatly improve the convenience and efficiency of operation.

[0042] In this embodiment, as Figure 4 As shown, the molding cavity is equipped with partitions 15. The number of partitions 15 needs to be selected according to the actual working conditions, such as one set, two sets, three sets, etc. By reasonably setting these partitions 15, a reinforcing structure can be constructed inside the double T beam. These reinforcing structures can be in the form of reinforcing ribs or reinforcing walls, etc. This structure gives the double T beam a certain load-bearing capacity and can effectively cope with various external forces. In addition, when the double T beam is long, the reinforcing structure can also reasonably divide it to avoid affecting the structural stability due to excessive length, thereby significantly improving the service life of the double T beam.

[0043] In this embodiment, both the upper and lower ends of the T-shaped block 12 are T-shaped structures to form an "I" shape. The T-shaped block 12 is provided with an upwardly extending connecting piece at the end near the double T-beam 50. After the double T-beam 50 is cast, the double T-beam 50 wraps the connecting piece inside it to ensure that the T-shaped block 12 and the double T-beam 50 can be stably connected, thereby ensuring the molding quality of the double T-beam 50.

[0044] Preferably, such as Figure 1-3As shown, the first fixing component 21 includes a first bracket 211, a first fixing forming plate 212, and a first support rod 213. The first bracket 211 is mounted on the base 10 via an adjusting bracket 214. One end of the first support rod 213 is fixed to the base 10, and the other end is fixed to the first bracket 211; the first support rod 213 is a support screw. The bottom end of the first fixing forming plate 212 is located on the side of the first bracket 211 near the T-shaped block 12 and abuts against the T-shaped block 12. By setting up a first bracket 211, a first fixed forming plate 212, and a first support rod 213, the operator can control the first bracket 211 to move closer to or further away from the T-block 12 by adjusting the first support rod 213. That is, by adjusting the free end of the first support rod 213, the distance between the first fixed forming plate 212 and the double T-beam can be adjusted, thereby moving the first fixed forming plate 212 closer to or further away from the T-block 12. This enables the rapid installation and disassembly of the first fixed forming plate 212, simplifies the installation and disassembly steps, shortens the installation and disassembly time, and thus improves the installation and disassembly efficiency of the device.

[0045] The first support 211 has a threaded fixed cylinder 214a at its bottom end. A support foot 214b is threadedly connected to the fixed cylinder 214a, and the support foot 214b abuts against the base 10. The first support 211 is mounted on the base 10 by adjusting the support 214a. The threaded fixed cylinder 214a and support foot 214b at the bottom end of the first support 211 allow adjustment of the height and level of the first support 211 by rotating the support foot 214b, accommodating the casting and molding of double T-beams 50 at different heights, thus improving the versatility of the device.

[0046] Furthermore, the first movable component 22 has a first movable forming plate. One end of the first movable forming plate is rotatably connected to the top of the first fixed forming plate 212 via a hinge. One end of the first control component 23 is fixedly connected to the top of the first support 211, and the other end is connected to the first movable forming plate, used to control the rotation of the first movable forming plate around the top of the first fixed forming plate 212. During demolding, operating the first control component 23, i.e., adjusting the free end of the first control component 23, to adjust the distance between the first movable forming plate and the double T-beam, allows the first movable forming plate to smoothly detach from the double T-beam. With the cooperation of the first fixed component 21, the outer mold component 20 can be quickly installed and disassembled, simplifying its assembly and disassembly steps, reducing the time and difficulty of manual operation, reducing labor intensity, and also reducing damage to the mold caused by improper operation, thus improving the service life of the mold.

[0047] Furthermore, the molding component 24 includes a first molding block 241 and a second molding block 242. The first molding block 241 is detachably mounted on the first movable molding plate and is used for side molding of the top of the double T-beam 50. The second molding block 242 is detachably mounted on the first molding block 241 and is used for top surface molding of the top of the double T-beam 50. The second molding block 242 is provided with multiple sets of first reinforcing bars 242a, and the second molding block 242 is provided with multiple sets of snap-fit ​​grooves for placing the first reinforcing bars 242a. When disassembling and assembling the outer mold, the first molding block 241 and the second molding block 242 must be removed sequentially to avoid interference between the first molding block 241 and the second molding block 242 and the removal of the first movable component 22.

[0048] Preferably, such as Figure 4-7 As shown, the second fixing component 31 includes a second bracket 311 and a second fixing forming plate 312. The second bracket 311 is movably mounted on the base 10 and located between the two sets of pads 11. The second fixing forming plate 312 is disposed on the side of the second bracket 311 near the T-shaped block 12 and abuts against the T-shaped block 12. During the installation and removal of the inner membrane, the operator can move the second fixing forming plate 312 closer to or further away from the T-shaped block 12 via the two sets of second brackets 311, thereby enabling the second fixing forming plate 312 to be installed and removed quickly, simplifying the installation and removal steps, shortening the installation and removal time, and thus improving the installation and removal efficiency of this device.

[0049] Furthermore, a bidirectional hydraulic cylinder 33 is provided between the bottom ends of the two sets of second supports 311, and the output ends of the bidirectional hydraulic cylinder 33 are respectively connected to the bottom ends of each set of second supports 311. The second supports 311 are provided with sliding wheels 34, and a slide rail 35 is provided between the sliding wheels 34 and the base 10. By setting the bidirectional hydraulic cylinder 33, and the second supports 311 sliding on the slide rail 35 via the sliding wheels 34, during demolding, only the bidirectional hydraulic cylinder 33 needs to be activated to make the two sets of second supports 311 move inward or outward simultaneously, driving the second fixed forming plate 312 and the second movable forming plate to smoothly detach from the double T beam, realizing automated operation, reducing manual intervention, and improving demolding efficiency.

[0050] In this embodiment, the sliding wheel 34 consists of three sets of rollers arranged in a triangular pattern. The top set of rollers is located above the slide rail 35, and the bottom two sets of rollers are located inside the slide rail 35. By setting the sliding wheel 34 with this structure, the second support 311 can slide more smoothly on the slide rail 35, thereby improving the sliding stability of the inner membrane assembly 30.

[0051] Furthermore, the second movable component 32 has a second movable forming plate. One end of the second movable forming plate is hinged to the top of the second fixed forming plate 312. One end of the second control component 33 is fixedly connected to the second fixed forming plate 312, and the other end is connected to the second movable forming plate. One set of second movable forming plates and the second support 311 are supported by a second support rod 34, which is a support screw. During demolding, the operator operates the second control component 33, that is, adjusts the free end of the second support rod 34, to adjust the distance between the second movable forming plate and the double T beam, thereby enabling the second movable forming plate to smoothly detach from the double T beam. The operation is simple and convenient. At the same time, the setting of the second support rod 34 enhances the connection stability between the second movable forming plate and the second support 311, preventing the second movable forming plate from shaking or deforming during concrete pouring and demolding, and ensuring the accuracy and quality of the internal forming of the double T beam.

[0052] In this embodiment, the second control element 33 can be set to two, three, or four sets in a certain group of inner membrane components 30. If there are two groups of inner membrane components 30, the second control element 33 inside each group can be set to three sets; or two sets of second control elements 33 can be set in one group and four sets of second control elements 33 can be set in the other group. The specific number and combination of the second control elements 33 need to be designed according to the actual working conditions, as long as the inner membrane components 30 can be quickly installed and disassembled.

[0053] Furthermore, the length of one set of second movable forming plates away from the second fixed forming plate 312 is longer than that of the other set of second movable forming plates away from the second fixed forming plate 312, and the second support rod 34 is connected to the lower part of the longer second movable forming plate. An inclined surface is provided between the two sets of second movable forming plates. By designing one set of second movable forming plates to be longer than the other, and by providing an inclined surface between the two sets of second movable forming plates, the longer second movable forming plate forms a limiting structure on the shorter second movable forming plate through the inclined surface, and the longer second movable forming plate is fixed by the second support rod 34, further improving the connection stability of the two sets of second movable forming plates during casting.

[0054] Preferably, such as Figure 1 , Figure 2 and Figure 6As shown, a first connecting rod 40 is provided between the first fixing component 21 and the second fixing component 31. Both the first fixing component 21 and the second fixing component 31 have a fixing seat 41 at their bottom ends. The first connecting rod 40 passes sequentially through the fixing seat 41 on the first fixing component 21, the pad 11, and the fixing seat 41 on the second fixing component 31, with both ends of the first connecting rod 40 fixed to the fixing seat 41 by nuts 43. A second connecting rod 42 is provided at the top of each of the two sets of first fixing components 21. Both ends of the second connecting rod 42 are fixed to the top of the first fixing component 21 by nuts 43. By setting the first connecting rod 40 and the second connecting rod 42, the first fixing component 21 and the second fixing component 31 are connected into a whole, increasing the rigidity and strength of the mold, enabling it to better withstand various external forces during concrete pouring, preventing deformation or displacement of the mold, and ensuring the forming accuracy and quality of the double-T beam. At the same time, the method of fixing with nuts 43 facilitates the installation and disassembly of the mold, improving production efficiency.

[0055] Preferably, such as Figure 1 and Figure 8 As shown, the first sealing plate assembly 13 has a first sealing plate, which is detachably connected to the outer mold mechanism and the inner mold mechanism. Multiple sets of second reinforcing bars 131 are provided on the first sealing plate. The second sealing plate assembly 13 includes a first side plate 141, a second sealing plate 142, and a second side plate 143. The first side plate 141, the second sealing plate 142, and the second side plate 143 form a wrapping structure located at the end of the molding cavity. The first side plate 141, the second sealing plate 142, and the second side plate 143 are detachably connected, and the first side plate 141 and the second side plate 143 are detachably connected to the outer mold mechanism and the inner mold mechanism, respectively. The top of the second sealing plate 142 has a horizontally positioned horizontal portion 142a. The detachable connection design of the first sealing plate, the first side plate 141, the second sealing plate 142, and the second side plate 143 facilitates installation and disassembly by operators, simplifies the assembly and disassembly components of the device, and effectively shortens the assembly and disassembly time.

[0056] The above are merely preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way.
