Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel truss technology, specifically to a detachable steel truss support connection component on a concrete structure. Background Technology
[0002] With the continuous development of the construction industry, the requirements for building materials and structural design are also increasing. Especially in high-rise buildings, long-span bridges and other projects, higher requirements are placed on the strength, stability and construction efficiency of the supporting structure. Although traditional reinforced concrete structures have good load-bearing capacity and durability, they still have certain limitations in some aspects, such as high construction complexity and long construction period. As an important supporting component, steel trusses are widely used in concrete structures to enhance their load-bearing capacity.
[0003] Traditional steel trusses are usually fixed to the bottom formwork using connectors. These connectors are connected to the bottom formwork one by one using bolts. Although this method can provide a certain degree of stability, it has significant limitations and challenges in practical applications.
[0004] During installation, each connection point needs to be secured individually with bolts, meaning each connection point must be operated one by one, making the entire installation process time-consuming and labor-intensive. Especially when dealing with large-scale or complex structures, this one-by-one fixing method greatly slows down the construction progress and increases labor costs and time consumption. Similarly, during the disassembly phase, each bolt needs to be loosened and removed one by one, which not only extends the project cycle but also increases the labor intensity and complexity.
[0005] Secondly, traditional installation methods cannot guarantee the consistency and uniformity of all connection points. Since the tightness of each connection point may vary, the connection between the steel truss and the bottom formwork may not be strong enough, thus affecting the safety and stability of the overall structure. Utility Model Content
[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing a detachable steel truss support connection component on a concrete structure, which makes installation and disassembly quick and simple, and easy to use.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A detachable steel truss support connection assembly on a concrete structure includes a bottom formwork and an installation strip. Truss connectors are fixedly installed at equal intervals on the installation strip. Protrusions are fixedly installed at both ends of the installation strip facing the bottom formwork. Limiting holes are opened on the protrusions. The bottom formwork has slots at corresponding positions that allow the limiting holes on the protrusions to be exposed. The bottom of the bottom formwork is provided with a limiting mechanism, a driving mechanism, and a locking mechanism.
[0009] Preferably, the limiting mechanism includes a mounting plate, which is slidably mounted on the bottom template. Limiting rods are fixedly mounted at equal intervals on the side of the mounting plate facing the protruding block, and the limiting rods are adapted to the limiting holes.
[0010] Preferably, the drive mechanism includes a mounting shaft and a driven gear plate. The mounting shaft is rotatably mounted on the bottom template, and a drive gear is fixedly mounted on the mounting shaft. There are two driven gear plates, both of which are slidably mounted on the bottom template. The ends of the two driven gear plates that are away from the drive gear are fixedly connected to the corresponding mounting plates.
[0011] Preferably, the teeth of the two passive gear plates face opposite directions, and the two passive gear plates are located on the upper and lower sides of the driving gear, respectively, and both passive gear plates are meshed with the driving gear.
[0012] Preferably, an operating block is fixedly mounted on the mounting shaft, and the operating block has a through groove.
[0013] Preferably, sliders are fixedly installed on the side of both passive toothed plates facing the bottom template, and the bottom template has grooves at the corresponding positions for the sliders to slide.
[0014] Preferably, the locking mechanism includes a limiting plate, which is fixedly installed on the bottom template and is located on the movement path of the operating block. The limiting plate and the operating block are connected by bolts. The limiting plate is provided with positioning through holes, through slots, and positioning through holes that are compatible with the bolts.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This invention utilizes the cooperation of a drive mechanism and a limiting mechanism to achieve synchronous limiting of multiple limiting holes, ensuring high efficiency and structural stability during construction. Furthermore, the simple operation process and efficient locking mechanism make installation and disassembly quick and easy, requiring no complex tools or lengthy adjustments. This not only significantly improves work efficiency and reduces labor costs but also enhances the safety and flexibility of the project.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Please see Figures 1 to 5 A detachable steel truss support connection assembly on a concrete structure includes a bottom formwork 1 and mounting strips 2. The mounting strips 2 are installed equidistantly on the bottom formwork 1 to enable subsequent installation of the steel truss.
[0025] The bottom formwork 1 can be a wooden formwork or a steel formwork. To ensure service life and performance, a steel formwork is preferred.
[0026] Truss connectors 3 are fixedly installed at equal intervals on the mounting strip 2. The steel truss is fixedly installed on the truss connectors 3 by welding or other methods, thus completing the installation of the steel truss.
[0027] Both ends of the mounting strip 2 facing the bottom template 1 are fixedly equipped with protruding blocks 4. Limiting holes 6 are opened on the protruding blocks 4. The bottom template 1 has slots 5 at the corresponding positions to expose the limiting holes 6 on the protruding blocks 4. During installation, the protruding blocks 4 are accurately inserted into the slots 5 of the bottom template 1 to expose them, which facilitates subsequent limiting activities. Through limiting, the mounting strip 2 and the bottom template 1 can be stably connected during pouring, and it is also convenient for subsequent disassembly.
[0028] It is worth noting that attention should be paid to sealing the gaps between the protruding block 4 and the slot 5, as well as the gaps between the mounting strip 2 and the bottom template 1, so as to prevent concrete from leaking accidentally through the gaps during the concrete pouring process.
[0029] The bottom of the bottom template 1 is equipped with a limit mechanism, a drive mechanism, and a locking mechanism.
[0030] The limiting mechanism includes a mounting plate 7, which is slidably mounted on the bottom template 1. Limiting rods 8 are fixedly mounted at equal intervals on the side of the mounting plate 7 facing the protruding block 4, and the limiting rods 8 are adapted to the limiting holes 6.
[0031] The position of the mounting plate 7 can be adjusted to control the movement of the limit rod 8. When in use, the limit rod 8 is inserted into the limit hole 6 to achieve the limiting function, so that the mounting strip 2 cannot move, thereby completing the limiting activity.
[0032] The drive mechanism includes a mounting shaft 13 and a driven gear plate 10. The mounting shaft 13 is rotatably mounted on the bottom template 1. A drive gear 9 is fixedly mounted on the mounting shaft 13. There are two driven gear plates 10. Both driven gear plates 10 are slidably mounted on the bottom template 1. The ends of the two driven gear plates 10 that are away from the drive gear 9 are fixedly connected to the corresponding mounting plates 7.
[0033] The two passive tooth plates 10 have opposite orientations and are located on the upper and lower sides of the driving gear 9, respectively, and both passive tooth plates 10 are meshed with the driving gear 9.
[0034] When the drive gear 9 rotates, it causes the two passive gear plates 10 to move in opposite directions. As a result, the two passive gear plates 10 can move to both sides of the bottom template 1, thereby causing the two mounting plates 7 to move in the same way and completing the synchronous positioning of multiple sets of side limit holes 6.
[0035] Preferably, the number of bottom drive mechanisms and limiting mechanisms of a bottom template 1 is not limited, and can be adjusted according to the actual length that can be driven.
[0036] An operating block 14 is fixedly installed on the mounting shaft 13. The operating block 14 has a through groove 16. By rotating the operating block 14, the mounting shaft 13 can drive the drive gear 9 to rotate, thereby completing the establishment or release of the limit activity.
[0037] Both passive toothed plates 10 are fixedly mounted with sliders 12 on the side facing the bottom template 1. The bottom template 1 has a groove 11 at the corresponding position for the sliders 12 to slide. The cooperation between the sliders 12 and the grooves 11 can ensure that the passive toothed plates 10 maintain stability and linear movement during the movement.
[0038] The locking mechanism includes a limiting plate 15, which is fixedly installed on the bottom template 1. The limiting plate 15 is located on the movement path of the operating block 14. The limiting plate 15 and the operating block 14 are connected by bolts 18. The limiting plate 15 has a positioning through hole 17, a through groove 16, and the positioning through hole 17 is adapted to the bolts 18.
[0039] After the system is adjusted to the required position (i.e., the limit rod 8 is inserted into the limit hole 6 to complete the limit movement), the operating block 14 abuts against the limit plate 15, and the center of the positioning hole 17 and the center of the through groove 16 are on the same straight line. By passing the bolt 18 through the through groove 16 and the positioning hole 17, the bolt 18 can be fixed by using a washer and nut, thus locking the position of the operating block 14 and preventing the drive gear 9 from rotating, thereby ensuring that the system is in a locked state and preventing accidents.
[0040] The working process of this utility model is as follows: First, the installation strip 2 is inserted into the slot 5 on the bottom template 1 through the protrusions 4 at both ends, ensuring that the limiting hole 6 is accurately exposed. In order to prevent leakage during the concrete pouring process, attention should be paid to sealing the gap between the protrusions 4 and the slot 5. The steel truss is fixed to the truss connector 3 by welding or other means to complete the installation of the steel truss.
[0041] By rotating the operating block 14 on the mounting shaft 13, the driving gear 9 drives the two passive gear plates 10 to move in opposite directions, thereby causing the two mounting plates 7 to move to both sides at the same time, so that the limiting rod 8 is inserted into the limiting hole 6, thus achieving a stable lock on the mounting strip 2.
[0042] After the system is adjusted to the correct position (i.e., the limit rod 8 has been correctly inserted into the limit hole 6), the operation block 14 is locked in the appropriate position by passing the bolt 18 through the through slot 16 on the operation block 14 and the positioning through hole 17 on the limit plate 15, so as to prevent the drive gear 9 from rotating accidentally and to ensure the stability of the system.
[0043] Then, reverse the operation to remove the restrictions and disassemble the bottom template 1.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
