Both ends of the internal frame protrude from both sides of the concrete beam respectively. A support steel rod is detachably fastened in the middle of the internal frame.

Description

Technical Field

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

[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 to hoist materials such as aluminum gusset plates and sheets to the designated 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 assembly and construction work on site. 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. Most of the temporary support structures use light steel or single-layer wire mesh, and their anti-lateral stress ability is weak. 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

[0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an integrated hanging support device for concrete beams in civil engineering to solve the problems mentioned in the above background technique.

[0004] To achieve the above purpose, the present invention is realized through the following technical solutions: An integrated hanging support device for concrete beams in civil engineering includes a concrete beam and an internal frame coagulated and arranged in the concrete beam. Both ends of the internal frame protrude from both sides of the concrete beam respectively. A support steel rod is detachably fastened in the middle of the internal frame, and the support steel rod penetrates through the left and right sides of the concrete beam;

[0005] The internal frame includes two horizontally arranged transverse frame rods and a longitudinal frame rod integrally arranged between the two transverse frame rods. A transverse rod sleeve is integrally arranged in the middle of the two longitudinal frame rods. Both ends of the transverse rod sleeve protrude from both sides of the concrete beam, and the support steel rod slides through the middle of the transverse rod sleeve;

[0006] Movable support plates are respectively installed on the lower sides of both ends of the support steel rod, and are locked and connected with the left and right ends of the internal frame through the movable support plates to form an integral body for lower side support;

[0007] The front, rear, left and right sides of both ends of the support steel rod are connected with a first side support rod and a second side support rod respectively, and are connected with the left and right ends of the internal frame through the first side support rod and the second side support rod to form an integral body for lateral support;

[0008] On both longitudinal frame bars on both sides of the transverse bar sleeve, there are integrally provided convex portions. The interiors of the transverse frame bar, the longitudinal frame bar, and the convex portions are all hollow and connected in communication. Inside the two convex portions, there is a tightening assembly that can relatively penetrate both sides of the transverse bar sleeve and tightly clamp on the front and rear sides of the support steel rod. And inside the transverse frame bar and the longitudinal frame bar, there is an adjustment assembly for driving the relative sliding displacement of the two tightening assemblies.

[0009] In a further preferred solution, a guide plate is fixedly provided inside the convex portion. A guide groove is longitudinally opened on the guide plate. The tightening assembly includes a top insertion rod longitudinally arranged inside the convex portion. A connecting rod is fixedly provided on the lower side of the top insertion rod, and the connecting rod is adaptively inserted through the guide groove. A threaded tube is integrally provided at the bottom end of the connecting rod, and the threaded tube is connected to the adjustment assembly. The top insertion rod is arranged to penetrate from the inside of the convex portion to the inside of the transverse bar sleeve and tightly press on the front and rear sides of the support steel rod.

[0010] In a further preferred solution, the adjustment assembly includes a transverse rotating rod rotatably installed inside the transverse frame bar and a longitudinal rotating rod rotatably installed inside the longitudinal frame bar. A first sector gear and a second sector gear that are meshed and driven with each other are installed on the transverse frame bar and the longitudinal rotating rod. Transmission threads are respectively oppositely arranged on the front and rear sides of the longitudinal rotating rod. The threaded tube is threadedly sleeved on the longitudinal rotating rod and is in threaded transmission connection with the corresponding transmission thread. Handwheels are installed at both ends of the transverse rotating rod, and the handwheels are located outside the transverse frame bar.

[0011] In a further preferred solution, movable extension rods are slidably inserted at both ends of the support steel rod, and the movable extension rods and the support steel rod are locked by screws. A reinforcing rib is integrally provided on the upper side of the movable extension rod, and the reinforcing rib and the movable extension rod are slidably inserted inside the support steel rod.

[0012] In a further preferred solution, notches are respectively opened in the middle of the front and rear sides of the support steel rod, and a plurality of clamping blocks are fixedly provided on the notches. The top insertion rod can be adaptively inserted into the notches of the two clamping blocks for clamping.

[0013] In a further preferred solution, the edges of the opposite sides of the clamping block and the top insertion rod are both provided with rounded corners.

[0014] In a further preferred solution, a plurality of L-shaped support corners are fixedly provided at the bottoms of the transverse frame bar and the longitudinal frame bar, and each L-shaped support corner protrudes toward both sides of the concrete beam. The L-shaped support corner of the longitudinal frame bar is located directly below the support steel rod. The support steel rod is screwed and locked to the outer end of the L-shaped support corner of the longitudinal frame bar through a movable support plate for strengthening the lower support.

[0015] In a further preferred solution, connecting frame plates are locked on the front and back sides of both ends of the supporting steel rod. The first side support rod and the second side support rod are movably hung on the connecting frame plates, and the other end of the first side support rod is connected to the outer end of the transverse frame rod, and the other end of the second side support rod is connected to the L-shaped support angle for strengthening the side support.

[0016] By adopting the above technical solutions, the present invention has the following advantages:

[0017] In the present invention, the built-in frame is condensed and integrated with the inner side of the concrete beam. This method not only has a fast construction efficiency, but also can improve the strength of the concrete beam and the connection stability between the built-in frame and the concrete beam after integration. This provides a good stable foundation for the supporting steel rod arranged in the middle of the built-in frame, enabling the supporting steel rods protruding from both ends of the concrete beam to have good support for hanging and supporting. Moreover, the bottoms of both ends of the supporting steel rod are connected to the outer ends of the condensed built-in frame through movable support plates to form an integral body, which can not only improve the lower side support strength of the supporting steel rod, but also enhance the stability of the supporting steel rod on the built-in frame and the concrete beam, avoiding displacement.

[0018] At the same time, both ends of the supporting steel rod are also 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 respectively to form an integral body, which also plays a role in limiting the supporting steel rod and improving the lateral support strength of the supporting steel rod, thereby ensuring the stable supporting effect of the supporting steel rod.

[0019] Secondly, the supporting steel rod is movably arranged in the middle of the built-in frame. During later replacement or maintenance, the supporting steel rod can be slid out, or the corresponding lengths of both ends of the supporting steel rod on both sides of the built-in frame and the concrete beam can be adjusted back and forth. The overall installation and use are very simple and flexible. Only by controlling the relative displacement of the tightening component inside the convex part through the adjusting component of the transverse rod sleeve and the longitudinal frame rod, the supporting steel rod can be quickly clamped or loosened inside the transverse rod sleeve. When clamped, the supporting steel rod can be limited, and when loosened, the supporting steel rod can be adjusted, making the use of the supporting steel rod very flexible and convenient, and more stable and effective than the existing structure. Moreover, movable extension rods are respectively slidably arranged inside both ends of the supporting steel rod, and the telescopic length of the movable extension rod can be adjusted according to the actual hanging requirements to determine the hanging position and then locked by bolts, further improving the use flexibility.

Detailed implementation manners

[0029] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0030] As Figures 1-7 shown, the present invention provides a concrete beam integral 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, and the support steel rod 3 penetrates through the left and right sides of the concrete beam 1. The way of coagulation between the concrete beam 1 and the built-in frame 2 can be quickly built, which improves the strength of the concrete beam 1 and enhances 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 better support for hanging.

[0031] 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 from 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 hoisting requirements on site. Activity support plates 4 are respectively installed on the lower sides of both ends of the support steel bar 3, and are locked and connected with the left and right ends of the built-in frame 2 through the activity support plates 4 to form an integral body for lower side support. Specifically, a plurality of L-shaped support corners 24 are fixedly arranged at the bottoms of the cross bars 21 and the longitudinal bar 22, and each L-shaped support corner 24 protrudes towards both sides of the concrete beam 1. The L-shaped support corner 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 locked with the outer ends of the L-shaped support corners 24 of the longitudinal bar 22 through the activity 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 activity support plates 4 at both ends of the support steel bar 3 also prevent 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 activity 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.

[0032] Both the front and back 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 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 on both the front and back 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 corner 24. In this way, an integral 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 activity support plate 4 can be combined to connect the support steel bar 3 and the built-in frame 2 into an integral body well. 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.

[0033] On both longitudinal frame bars 22 on the front and rear sides of the transverse bar sleeve 23, there are integrally provided convex portions 221, so that the transverse bar sleeve 23 can be more stably arranged between the two convex portions 221. The transverse frame bar 21, the longitudinal frame bar 22 and the inside 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, it is not easy for concrete to enter the hollow cavity inside during the bonding of the transverse frame bar 21 and the longitudinal frame bar 22 to the concrete beam 1, and 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.

[0034] 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 and guided to slide by the guide groove 223. 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 abuts 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, transmission threads 721 are respectively oppositely arranged. The threaded tube 82 is threadedly sleeved on the longitudinal rotating rod 72 and is in threaded transmission connection with the corresponding transmission 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 transmission 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 assemblies 8, making the top insertion rods 81 relatively tightly abut or disengage from the support steel rod 3, thereby controlling the clamping or loosening of the support steel rod 3 in the transverse bar sleeve 23, realizing the adjustment and control of the support steel rod 3, and greatly improving the use flexibility and effect of the structure.

[0035] 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 combination 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 suspended downward 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 whole 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, so as to ensure that the movable extension rod 31 can provide good support strength when suspending or hanging items.

[0036] 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 the position of the supporting steel rod 3 needs to be adjusted, 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 the realization of the adjustment function of the supporting steel rod 3.

[0037] The edges on the opposite sides of the clamping block 34 and the top insertion rod 81 are both provided with chamfered edges. 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 edges 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 edges can reduce the wear of the opposite edges of the clamping block 34 and the top insertion rod 81. Right-angle edges are prone to generate large frictional forces and stress concentrations during contact, while the chamfered edges 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.
