Description

Technical Field

[0001] This invention relates to an assembly construction device, and more particularly to an assembly construction device and method for steel truss composite beams. Background Technology

[0002] Although steel truss bridges are relatively simple to design, fabricate, and install, and can accommodate a wide range of spans, they also have a large structural space, relatively low overall structural stiffness, and high beam height, typically 1 / 12 to 1 / 8 of the span. The weak lateral stiffness of steel trusses necessitates numerous transverse supports to connect the trusses into a unified structure, providing spatial stiffness to resist longitudinal and transverse forces. This leads to the development of composite steel truss beams. To improve the construction efficiency and effectiveness of these composite beams, assembly construction is employed. Therefore, assembly construction devices and methods for steel truss composite beams are crucial construction techniques. Current assembly construction devices and methods typically involve internally installed steel-reinforced cages to increase the overall strength of the steel truss and resist the longitudinal and transverse forces generated by the concrete's self-weight. However, the cages are fixedly connected to the concrete, lacking a flexible buffer zone. Under significant impacts or heavy loads, internal stress can occur, causing the concrete to crack and affecting the quality of the steel truss composite beam assembly construction.

[0003] This invention, through its technical feature of providing flexible rope support within embedded concrete, effectively explores and studies the technical problem of cracking caused by internal stress in steel-reinforced cages when subjected to significant impact or heavy weight.

[0004] The statements herein provide only background information related to this invention and do not necessarily constitute prior art. Based on the technical disclosure provided by the applicant on September 9, 2023, which addresses practical technical problems encountered during the work process, and through searching similar patent documents and existing technical problems, technical features, and technical effects in the background art, the technical solution of this invention is proposed.

[0020] The technical effect of the above solution is that it enables rope connection between the beam plates of the steel truss composite beam, and the beam plates of the steel truss composite beam are supported by taut ropes.

[0021] This invention designs a threaded cylindrical shell comprising a cylindrical portion, a disc portion, and a toothed portion. The inner end of the peripheral side of the cylindrical portion is connected to the disc portion, the outer end of the peripheral side of the cylindrical portion is connected to the root of the toothed portion, and the cylindrical portion is threadedly connected to a threaded column.

The column portion is configured as a block-shaped body, and the strip portion I and the strip portion II are respectively configured as D-shaped strips with threaded bodies on their outer surfaces.

[0026] The present invention designs a clamping cylinder shell as a tubular body with a convex inner bore, wherein the extended part of the inner bore of the clamping cylinder shell is configured to be threadedly connected to the clamping column, and the contracted part of the inner bore of the clamping cylinder shell is configured to be connected to the tensioning rope sleeve.

[0027] The technical effect of the above two solutions is that they achieve the clamping treatment of the end of the tension rope, preventing the tension rope in the taut state from loosening.

[0028] The present invention designs a sleeve that is a nylon cylindrical body and is embedded in the beam plate of the steel truss composite beam, and the sleeve is connected to the tension rope set.

[0029] The technical effect of the above solution is that it protects the end of the tension rope and prevents damage to the beam plates of the steel truss composite beam.

[0030] The present invention is designed such that the tensioning rope, threaded cylinder shell, threaded column, rotating handle, clamping column and clamping cylinder shell are arranged in a tensioning built-in manner, and the tensioning rope, threaded cylinder shell, threaded column, rotating handle, clamping column and clamping cylinder shell and sleeve are arranged in an end-fitting manner.

[0031] The present invention is designed to consist of a threaded cylinder shell, a threaded column, a rotating handle, a clamping column, and a clamping cylinder shell forming a set of external pulling components. Two sleeves and two sets of external pulling components are set on a tension rope.

[0034] This invention designs an assembly construction method for a steel truss composite beam, the steps of which are: a tensioning rope is used to make the concrete poured between the beam plates of the steel truss composite beam serve as an internal skeleton, and an external tensioning device is used to apply tension to the tensioning rope, thereby achieving flexible rope support for the embedded concrete.

[0035] The technical effects of the above solutions are: to achieve internal connection of the steel truss composite beam, to achieve rope support for the concrete, and to ensure that the concrete is in a stable state.

[0036] The present invention comprises the following steps: During the assembly construction of the steel truss composite beam, process holes are formed on the beam body plates of the steel truss composite beam; sleeves are installed in the process holes of the beam body plates of the steel truss composite beam; according to the assembly relationship of the beam body plates of the steel truss composite beam, the beam body plates of the steel truss composite beam are installed in the template of the steel truss composite beam; tension ropes are installed in the sleeves; and the end of the tension rope is placed in the clamping cylinder shell. In the contraction section of the inner bore, when the end of the tension rope is placed between bar I and bar II, the expansion section of the inner bore of the clamping cylinder rotates on bar I and bar II. When the clamping cylinder is tightened to the clamping column, bar I and bar II clamp the end of the tension rope, causing the cylinder to rotate on the threaded column. This causes the disc to act on the outer end face of the beam plate of the steel truss composite beam, aligning bar I and bar II in a straight line. Part I and Rod II are placed into the mounting hole. Through Rod I and Rod II, a rotational torque is applied to the threaded column, causing the threaded column to rotate outward in the cylinder, which in turn moves the tension rope outward. When the tension rope in the beam plate of the steel truss composite beam is taut, Rod II is rotated and placed between the teeth. Concrete mortar is poured between the beam plates of the steel truss composite beam, and the concrete is cured. After the steel truss composite beam is assembled, Rod II is rotated in the opposite direction and removed from between the teeth, so that Rod I and Rod II are in a straight line. Rod I and Rod II are removed from the mounting hole. The cylinder is rotated in the opposite direction on the threaded column, separating the cylinder from the threaded column. The inner bore extension of the clamping cylinder shell is rotated in the opposite direction on Strip I and Strip II, separating the clamping cylinder shell from the clamping column. The end of the tension rope is removed from Strip I and Strip II.

[0037] The technical effect of the above solution is that it enables the assembly and construction of steel truss composite beams with built-in tension ropes, and realizes the tension ropes in a tensioned state as a support.

[0038] The present invention is designed with the following steps: placing water-based polyurethane resin in one container, placing glass fiber filaments in another container, placing the middle part of a tension rope in one of the containers, dipping the middle part of the tension rope in water-based polyurethane resin, placing the tension rope containing water-based polyurethane resin in the other container, bonding glass fiber filaments to the middle part of the tension rope, combing the glass fiber filaments on the tension rope, and connecting the fiber body to the tension rope after the water-based polyurethane resin has solidified.

[0039] The technical effect of the above solution is that it enables the additional extension of the tensioning rope.

[0040] In this technical solution, the tension rope is a basic component and an essential technical feature of the invention. The sleeve, threaded cylinder shell, threaded column, rotating handle, clamping column, clamping cylinder shell, adhesive layer, and fiber body are functional components and features that achieve other technical effects of the invention. The design of the beam body plates, cylinder, disc, toothed part, mounting hole, receiving hole, rod part I, rod part II, pin, column part, strip part I, and strip part II of the steel truss composite beam are technical features that comply with the Patent Law and its implementing regulations.

[0070] A method for assembling and constructing a steel truss composite beam, one of the first embodiments of the present invention, comprises the following steps: During the assembly and construction of the steel truss composite beam, process holes are formed on the beam body plate 1 of the steel truss composite beam; a sleeve 3 is installed in the process holes of the beam body plate 1 of the steel truss composite beam; according to the assembly relationship of the beam body plates 1 in the steel truss composite beam, the beam body plates 1 of the steel truss composite beam are installed in the template of the steel truss composite beam; a tension rope 2 is installed in the sleeve 3; and the end of the tension rope 2 is placed in the clamp. In the contraction section of the inner bore of the cylinder shell 6, when the end of the tension rope 2 is placed between strip I 52 and strip II 53, the expansion section of the inner bore of the clamping cylinder shell 6 rotates on strip I 52 and strip II 53. When the clamping cylinder shell 6 is tightened with the clamping column 5, strip I 52 and strip II 53 clamp the end of the tension rope 2, causing the cylinder 41 to rotate on the threaded column 8, causing the disc 42 to act on the outer end face of the beam plate 1 of the steel truss composite beam, so that rod I 91 and rod II 92 are aligned in a straight line. Rod I 91 and rod II 92 are placed into the mounting hole 81. Through rod I 91 and rod II 92, a rotational torque is applied to the threaded post 8, causing it to rotate outwards within the cylinder 41. This rotates the tension rope 2 outwards. When the tension rope 2 in the beam plate 1 of the steel truss composite beam is taut, rod II 92 is rotated and positioned between the teeth 43. Concrete mortar is then poured between the beam plates 1 of the steel truss composite beam, and the concrete is cured. After the steel truss composite beam is assembled and formed... Rotate rod II 92 in the opposite direction to remove it from between teeth 43, align rod I 91 and rod II 92 in a straight line, remove rod I 91 and rod II 92 from mounting hole 81, rotate cylinder 41 in the opposite direction on threaded post 8, separate cylinder 41 from threaded post 8, rotate the inner bore extension of clamping cylinder 6 in the opposite direction on strip I 52 and strip II 53, separate clamping cylinder 6 from clamping post 5, and remove end of tension rope 2 from strip I 52 and strip II 53.

[0071] Figure 4 This is the second embodiment of the first embodiment of the present invention. This embodiment is described in detail with reference to the accompanying drawings. It includes an adhesive layer 30 and a fiber body 40. The adhesive layer 30 is disposed between the adhesive layer 30 and the tension rope 2. The inner surface of the adhesive layer 30 is configured to be connected to the tension rope 2, and the outer surface of the adhesive layer 30 is configured to be connected to the fiber body 40. The adhesive layer 30 is a water-based polyurethane resin coagulated layer, and the fiber body 40 is a glass fiber filament.

[0072] The adhesive layer 30 and the fiber body 40 form a support connection point for the tension rope 2. The adhesive layer 30 realizes the connection with the tension rope 2, and the fiber body 40 realizes the addition of a connection part to the tension rope 2. Its technical purpose is to serve as a component for increasing the strength of the connection to the sleeve 3.

[0073] A method for assembling and constructing a composite steel truss beam, the second embodiment of the present invention, comprises the following steps: placing water-based polyurethane resin in one container, placing glass fiber filaments in another container, placing the middle part of a tension rope 2 in one of the containers, dipping the middle part of the tension rope 2 in water-based polyurethane resin, placing the tension rope 2 with water-based polyurethane resin in the other container, bonding glass fiber filaments to the middle part of the tension rope 2, combing the glass fiber filaments on the tension rope 2, and after the water-based polyurethane resin has solidified, connecting the fiber body 40 to the tension rope 2.

[0074] In verifying this invention, the inventors abandoned the existing technical feature of using steel-reinforced cages, which would generate internal stress and cause concrete cracking under large impacts or heavy weight. Instead, they first proposed a technical feature of flexible rope internal support embedded in the concrete, resulting in the first unexpected technical effect: reducing the concrete construction period between the beam plates 1 of the steel truss composite beam. The second unexpected technical effect: the interconnected connection between the beam plates 1 of the steel truss composite beam ensures the smooth flow of concrete between the beam plates 1 and the steel truss composite beam. The overall state of the concrete resulted in a third unexpected technical effect: the redistribution and installation of the beam plate 1 of the steel truss composite beam in the concrete pouring state improved the installation accuracy of the beam plate 1 of the steel truss composite beam. This resulted in a fourth unexpected technical effect: the addition of an external friction force layer to the tension rope 2 prevented the tension rope 2 from exhibiting reverse cross-movement. This resulted in a fifth unexpected technical effect: the connection strength between the tension rope 2 and the concrete between the beam plate 1 of the steel truss composite beam and the beam plate 1 of the steel truss composite beam increased, thereby improving the support strength of the steel truss composite beam.

[0075] In a second embodiment of the present invention, the tension rope 2 and the external tensioning device are connected to each other in a manner that provides flexible rope support within the embedded concrete.

[0076] In this embodiment, the tensioning rope 2 is connected to the external tensioning device in such a way that the concrete poured between the beam plates 1 of the steel truss composite beam is used as the internal skeleton.

[0077] In this embodiment, the external tensioning device is configured to include a threaded cylinder shell 4, a threaded column 8, a rotating handle 9, a clamping column 5, and a clamping cylinder shell 6.

[0078] In this embodiment, a first attachment device is also included, and the first attachment device is disposed between the tension rope 2 and the beam plate 1 of the steel truss composite beam. The first attachment device is configured as a sleeve 3.

[0079] In this embodiment, a second attachment device is also included and is disposed between the tension rope 2 and the beam plate 1 of the steel truss composite beam. The second attachment device is configured to include an adhesive layer 30 and a fiber body 40.

[0080] The second embodiment of the present invention is based on the first embodiment.

[0081] This invention has the following characteristics:

[0082] 1. Due to the design of tension rope 2 and external tensioning device, the concrete between the beam plates 1 of the steel truss composite beam is used as an internal skeleton through tension rope 2, and the tensioning device applies tension force to tension rope 2 through external tensioning device, realizing flexible rope internal support for the embedded concrete. This solves the technical problem that the use of steel-reinforced cages will cause internal stress and concrete cracking when subjected to large impacts or large self-weight, thus improving the assembly and construction quality of steel truss composite beam.

[0083] 2. Due to the design of the threaded cylinder shell 4, threaded column 8, rotating handle 9, clamping column 5 and clamping cylinder shell 6, the tensioning rope 2 can be tightened.

[0084] 3. Due to the design of the sleeve 3, the end protection treatment of the tension rope 2 is realized.

[0085] 4. Due to the design of the adhesive layer 30 and the fiber body 40, the concrete between the beam plates 1 of the steel truss composite beam is provided with internal fiber support.

[0086] 5. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0087] 6. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.

[0088] Other technical features connected to the tension rope 2 and the external tensioning device that provide flexible internal support for the embedded concrete are also embodiments of the present invention. Furthermore, the technical features of the above embodiments can be combined in any way. In order to meet the requirements of the Patent Law, the Implementing Regulations of the Patent Law and the Examination Guidelines, all possible combinations of the technical features in the above embodiments will not be described.

[0089] Therefore, in the technical field of assembly and construction devices and methods for steel truss composite beams, any technical content that includes tensioning ropes 2 installed between the beam plates 1 of the steel truss composite beam and external tensioning devices installed between the tensioning ropes 2 and the beam plates 1 of the steel truss composite beam is within the protection scope of this invention.
