Description

Technical Field

[0001] The present invention specifically relates to an integrated hanging support device for concrete beams in civil engineering, and pertains to the technical field of building support formwork. Background Art

[0002] During the construction of concrete beams, it is often necessary to additionally build a temporary hanging device and a steel structure support system at the top for hoisting materials such as aluminum gusset plates and sheets to a specified height. Such requirements are particularly prominent in large cantilever beam scenarios. However, usually, the traditional hanging support structure of concrete beams requires a large amount of on-site assembly and construction work. This process is time-consuming and laborious, with low construction efficiency. Moreover, limited by site conditions, there are great safety hazards in high-altitude operations. The hanging support device and the concrete beam are in a split structure and are only connected by anchor bolts or clamping parts, unable to utilize the stiffness of the beam body itself. Under long-term loads, the connection nodes are prone to loosen due to stress concentration, and even cause local cracking of the beam body. In addition, most of the temporary support structures use light steel or single-layer wire meshes, which have weak lateral stress resistance. In the construction of large cantilever beams, wind loads or eccentric loads are likely to cause the support structure to become unstable, and the support position cannot be flexibly adjusted according to the site. The overall support strength and stability are not ideal. Therefore, there is an urgent need to propose an integrated hanging support device for concrete beams in civil engineering to improve the above problems. Summary of the Invention

[0005] A further preferred solution is that a guide plate is fixedly provided on the inner side of the raised portion, and a guide groove is longitudinally opened on the guide plate.

[0006] According to a further preferred solution, the adjustment assembly includes a transverse rotating rod rotatably installed inside the transverse frame rod and a longitudinal rotating rod rotatably installed inside the longitudinal frame rod, the transverse frame rod and the longitudinal rotating rod are equipped with a first sector gear and a second sector gear that mesh with each other for transmission, transmission threads are respectively arranged relatively on the front and rear sides of the longitudinal rotating rod, the threaded tube is threadedly sleeved on the longitudinal rotating rod and is threadedly connected with the corresponding transmission thread, hand wheels are installed at both ends of the transverse rotating rod, and the hand wheels are located on the outside of the transverse frame rod.

[0007] According to a further preferred solution, movable extension rods are slidably embedded in both ends of the support steel rod, and the movable extension rods are locked to the support steel rod by screws. Reinforcing ribs are integrally provided on the upper side of the movable extension rod, and the reinforcing ribs are slidably embedded in the inner side of the support steel rod together with the movable extension rod.

[0008] According to a further preferred solution, slots are respectively provided in the middle of the front and rear sides of the support steel rod, and a plurality of clamping blocks are fixed on the slots, and the top insertion rod can be adapted to be inserted into the inner sides of the slots of the two clamping blocks for clamping.

[0009] According to a further preferred solution, the edges of the clamping block and the ejection rod on the opposite side are both rounded.

[0010] According to a further preferred solution, a plurality of L-shaped support angles are fixedly provided at the bottom of the transverse frame bar and the longitudinal frame bar, and each L-shaped support angle is respectively protruded toward both sides of the concrete beam, and the L-shaped support angle of the longitudinal frame bar is located directly below the supporting steel rod, and the supporting steel rod is locked and connected to the outer end screws of the L-shaped support angle of the longitudinal frame bar through a movable supporting plate, so as to strengthen the lower side support.

[0011] A further preferred solution is that connection frame plates are locked on the front and back sides of both ends of the support steel rod.

Moreover, the bottom of both ends of the support steel rod is connected to the outer end of the condensed built-in frame through movable support plates to form an integral body, which can not only improve the lower support strength of the support steel rod, but also enhance the stability of the support steel rod on the built-in frame and the concrete beam, avoiding displacement. At the same time, both ends of the support steel rod are also respectively connected to both ends of the built-in frame protruding from both sides of the concrete beam through the first side support rod and the second side support rod to form an integral body, which also plays a role in limiting the support steel rod and improving the lateral support strength of the support steel rod, thereby ensuring the stable support effect of the support steel rod.

Specific embodiments

[0014] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0015] As Figure 1-7 shown, the present invention provides a concrete beam integrated hanging support device for civil engineering, including a concrete beam 1 and a built-in frame 2 coagulated in the concrete beam 1. Both ends of the built-in frame 2 protrude from both sides of the concrete beam 1 respectively. Among them, a support steel rod 3 is detachably fastened in the middle of the built-in frame 2. The support steel rod 3 penetrates through the left and right sides of the concrete beam 1. The coagulation method of the concrete beam 1 and the built-in frame 2 can be quickly built, improving the strength of the concrete beam 1 and enhancing the connection stability between the built-in frame 2 and the concrete beam 1, providing a stable foundation for the support steel rod 3 and enabling the support steel rod 3 to have good support for hanging.

[0016] The built-in frame 2 includes two horizontally arranged cross bars 21 that are parallel to each other and a longitudinal bar 22 integrally arranged between the two cross bars 21. A transverse bar sleeve 23 is integrally arranged in the middle of the two longitudinal bars 22. The two ends of the transverse bar sleeve 23 protrude on both sides of the concrete beam 1, and the support steel bar 3 is slidably inserted through the middle of the transverse bar sleeve 23, so that the support steel bar 3 can adjust the position of both ends of the support steel bar 3 on both sides of the concrete beam 1 according to the on-site hoisting requirements. Movable support plates 4 are respectively installed on the lower sides of both ends of the support steel bar 3, and are tightly locked and connected with the left and right ends of the built-in frame 2 through the movable support plates 4 to form an integral body for lower side support. Specifically, a plurality of L-shaped support angles 24 are fixedly arranged at the bottoms of the cross bars 21 and the longitudinal bar 22, and each L-shaped support angle 24 protrudes towards both sides of the concrete beam 1. The L-shaped support angle 24 of the longitudinal bar 22 is located directly below the support steel bar 3. Both ends of the support steel bar 3 are respectively screwed and tightly connected with the outer ends of the L-shaped support angles 24 of the longitudinal bar 22 through the movable support plates 4, and form an integral body to strengthen the lower side support function, improve the stability of the support steel bar 3 on the built-in frame 2 and the concrete beam 1, and the fact that both ends of the support steel bar 3 are respectively connected with the L-shaped support angles 24 through the movable support plates 4 also prevents the support steel bar 3 from moving out of place. The overall structure is highly stable. In this way, after the support steel bar 3 is stressed, the movable support plate 4 can transmit the force to the entire built-in frame 2 and the concrete beam 1, thereby ensuring the overall stable support effect.

[0017] Both the front and rear sides of both ends of the support steel bar 3 are connected with a first side support bar 5 and a second side support bar 6, and are tightly locked and connected with the two ends of the built-in frame 2 through the first side support bar 5 and the second side support bar 6 to form an integral body for lateral support. Specifically, connection frame plates 9 are locked and fixed on both the front and rear sides of both ends of the support steel bar 3. The first side support bar 5 and the second side support bar 6 are movably hung on the connection frame plates 9, and the other end of the first side support bar 5 is connected with the outer end of the cross bar 21, and the other end of the second side support bar 6 is connected with the L-shaped support angle 24. In this way, an overall structure is also formed to strengthen the stable support on the side of the support steel bar 3. That is to say, the above-mentioned first side support bar 5, second side support bar 6 and movable support plate 4 are used in combination, which can well connect the support steel bar 3 and the built-in frame 2 into an integral body. While playing a limiting role, it greatly improves the stability of the support structure of the support steel bar 3 and can transmit the force to the concrete beam 1 well.

[0018] On the longitudinal frame bars 22 on both the front and rear sides of the transverse bar sleeve 23, there are integrally provided convex portions 221. This enables the transverse bar sleeve 23 to be more stably arranged between the two convex portions 221. The transverse frame bar 21, the longitudinal frame bar 22, and the interior of the convex portion 221 are all hollow and connected in communication. On the inner sides of the two convex portions 221, there is a tightening assembly 8 that can relatively penetrate both sides of the transverse bar sleeve 23 and tightly clamp on the front and rear sides of the support steel rod 3. Inside the transverse frame bar 21 and the longitudinal frame bar 22, there is an adjustment assembly 7 for driving the relative sliding displacement of the two tightening assemblies 8. The hollow design of the transverse frame bar 21 and the longitudinal frame bar 22 can provide an installation space for the adjustment assembly 7, and the hollow design inside the convex portion 221 provides a sliding space for the tightening assembly 8. Moreover, since both ends of the transverse frame bar 21 protrude outside the concrete beam 1, when the transverse frame bar 21 and the longitudinal frame bar 22 are bonded to the concrete beam 1, it is not easy for concrete to enter the interior of the hollow cavity and cause an impact. The transverse frame bar 21 also provides an outer end connection point to connect with the support steel rod 3 to form an integral body.

[0019] Among them, a guide plate 222 is fixedly provided on the inner side of the convex portion 221. A guide groove 223 is longitudinally opened on the guide plate 222. The tightening assembly 8 includes a top insertion rod 81 longitudinally arranged on the inner side of the convex portion 221. A connecting rod 83 is fixedly provided on the lower side of the top insertion rod 81, and the connecting rod 83 can be adaptively inserted through the guide groove 223 for guiding and sliding. At the bottom end of the connecting rod 83, a threaded tube 82 is integrally provided, and the threaded tube 82 is connected to the adjustment assembly 7. The top insertion rod 81 is arranged to penetrate from the inner side of the convex portion 221 to the inner side of the transverse bar sleeve 23 and tightly clamp on the front and rear sides of the support steel rod 3. The adjustment assembly 7 includes a transverse rotating rod 71 rotatably installed inside the transverse frame bar 21 and a longitudinal rotating rod 72 rotatably installed on the inner side of the longitudinal frame bar 22. A first sector gear 73 and a second sector gear 74 that are meshed and driven with each other are installed on the transverse frame bar 21 and the longitudinal rotating rod 72. On the front and rear sides of the longitudinal rotating rod 72, driving threads 721 are respectively oppositely arranged. The threaded tube 82 is threadedly sleeved on the longitudinal rotating rod 72 and is in threaded driving connection with the corresponding driving thread 721. Handwheels 75 are installed at both ends of the transverse rotating rod 71, and the handwheels 75 are located outside the transverse frame bar 21. Therefore, by rotating the handwheels 75 at both ends of the transverse rotating rod 71, the longitudinal rotating rod 72 is driven to rotate through the transmission of the first sector gear 73 and the second sector gear 74, so that the two oppositely arranged driving threads 721 respectively drive the threaded tubes 82 of the two opposite tightening assemblies 8, driving the relative or opposite sliding displacement of the top insertion rods 81 of the tightening assembly 8, making the top insertion rods 81 relatively tightly clamp or disengage from the support steel rod 3, thereby controlling the clamping or loosening of the support steel rod 3 inside the transverse bar sleeve 23 and realizing the adjustment and control of the support steel rod 3, greatly improving the use flexibility and effect of the structure.

[0020] Both ends of the supporting steel rod 3 are slidably inserted with movable extension rods 31. After extending to the required length, the movable extension rod 31 and the supporting steel rod 3 are locked by screws or bolts. A reinforcing rib 32 is integrally provided on the upper side of the movable extension rod 31. The reinforcing rib 32 and the movable extension rod 31 are slidably inserted into the inner side of the supporting steel rod 3. Such an insertion method enables the reinforcing rib 32 to strengthen the structure inside the supporting steel rod 3, and the reinforcing rib 32 can enhance the structural strength of the supporting steel rod 3. When the movable extension rod 31 is in use, it can be used in conjunction with a steel rope guide pulley, that is, the guide pulley is installed at the end of the movable extension rod 31 (as Figure 7 shown), and then in cooperation with an external winch, steel rope and hook, the steel rope is allowed to hang down along the guide pulley at the end of the movable extension rod 31, and the movable extension rod 31 is used for stable support, so that the movable extension rod 31 on the supporting steel rod 3 can provide good support strength when suspending or hanging items. When the movable extension rod 31 on the supporting steel rod 3 is used to suspend or hang items, the weight of the item will generate a downward pulling force on the movable extension rod 31. Due to the existence of the reinforcing rib 32, it can share the pulling force borne by the movable extension rod 31 and increase the ability of the entire structure to resist deformation. Specifically, the reinforcing rib 32 can prevent the supporting steel rod 3 from bending or deforming excessively when subjected to the pulling force of the suspended item, thereby ensuring that the movable extension rod 31 can provide good support strength when suspending or hanging items.

[0021] Notches 33 are respectively formed in the middle parts of the front and rear sides of the supporting steel rod 3, and a plurality of clamping blocks 34 are fixed on the notches 33. When the supporting steel rod 3 bears weight or pressure, these clamping blocks 34 can share the force together to improve the strength of the supporting steel rod 3. The top insertion rod 81 can be adaptively inserted into the inner sides of the notches 33 of the two clamping blocks 34 for clamping. This clamping method can accurately limit the position of the supporting steel rod 3 in the transverse rod sleeve 23. When the top insertion rod 81 is inserted, the movement of the supporting steel rod 3 in the transverse direction is restricted, so as to ensure that the supporting steel rod 3 maintains a stable position during normal use and avoid unnecessary lateral displacement due to external forces and other factors. When it is necessary to adjust the position of the supporting steel rod 3, the setting of the clamping blocks 34 and the notches 33 does not affect the sliding displacement of the supporting steel rod 3 in the transverse rod sleeve 23. When the top insertion rod 81 is released, the supporting steel rod 3 can slide freely for adjustment, and the existence of the clamping blocks 34 can quickly achieve accurate positioning and clamping when the top insertion rod 81 is reinserted, assisting in the realization of the adjustment function of the supporting steel rod 3.

[0022] The edges on the opposite sides of the clamping block 34 and the top insertion rod 81 are both provided with chamfered corners. When the top insertion rod 81 is inserted into the notch 33 between the clamping blocks 34 for clamping operation, the design of the chamfered corners can reduce the resistance during insertion. Compared with the right-angle edges, the chamfered edges are smoother, making it easier for the top insertion rod 81 to align with the space between the clamping blocks 34, thus facilitating and quickly completing the insertion and clamping action, improving the convenience, accuracy, and stability of the operation. During the process of inserting and pulling out the top insertion rod 81 multiple times, the design of the chamfered corners can reduce the wear of the opposite edges of the clamping block 34 and the top insertion rod 81. The right-angle edges are prone to generate large friction and stress concentration during contact, while the chamfered corners can make the contact stress more evenly distributed, reducing the speed of edge wear, extending the service life of the clamping block 34 and the top insertion rod 81, and ensuring the long-term stable limiting and supporting functions of the structure.
