Description

Technical Field

[0001] The invention relates to the technical field of assembled buildings, in particular to an auxiliary connection device for assembled concrete beams, columns and floor slabs. Background Art

[0002] Prefabricated construction is an emerging construction technology, which is characterized by transferring most of the work in the traditional construction process from the construction site to the factory, and prefabricating various building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) in the factory, and then transporting these prefabricated components and accessories to the construction site, and assembling them into a complete building structure on site through reliable connection methods. The advantages of prefabricated construction include standardized manufacturing processes, easy large-scale production and simple construction processes, so it has developed rapidly in recent years.

[0003] After the current prefabricated concrete beams, columns and floor slabs are assembled, the floor slabs are fixed to the ground with concrete or mortar. Before fixing, the positions of multiple floor slabs need to be leveled and fixed. The height difference of the upper surfaces of each prefabricated slab depends entirely on the construction level of the construction workers. Therefore, this method is not only difficult to level and inefficient, but also difficult to guarantee the effect after construction. At the same time, the internal parts of the existing prefabricated connection devices are complicated, which will cause the bearing strength of the main frame to decrease. Under the prefabricated structure, the floor slabs that are prefabricated in advance still cannot form a whole after the accessories are put together, which will pose certain safety hazards.

[0004] Based on this, it is necessary to propose an auxiliary connection device for assembled concrete beams, columns and floor slabs. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an auxiliary connection device for assembled concrete beams, columns and floor slabs, which has the advantages of being able to form a whole by assembling multiple prefabricated panels together and having strong stability. At the same time, the assembly steps are relatively simple and the construction is convenient, thus solving the problems raised in the background technology.

[0006] The present invention provides the following technical solution: an auxiliary connection device for assembled concrete beams, columns and floor slabs, comprising a beam-column body and a prefabricated floor slab: Grooves are provided on both sides of the prefabricated floor slab, and cross bracing beams and columns are clamped inside the grooves. Embedded channel steels are provided on both side surfaces of the prefabricated floor slab. There are multiple prefabricated floor slabs, and cross beams are provided on two sides of the prefabricated floor slabs. Support steels are provided on the other two sides of the prefabricated floor slabs. Both ends of the support steels are fixedly connected with clamping joints, and the bottom end of the clamping joints is fitted with the inner bottom surface of the end of the cross beam, and the top of the beam-column body is fixedly welded to the bottom of both ends of the cross beam.

[0007] As a further improvement of the present invention, the crossbeam is L-shaped, and a plurality of steel bar clamps are fixedly connected to the inner bottom of the crossbeam. A sleeve groove is provided on the surface of the clamping joint, and the sleeve groove is sleeved on the steel bar clamp at the end of the crossbeam. The two pairs of supporting steel sections and the crossbeam form a rectangle.

[0008] By arranging in this way, a supporting steel frame can be formed.

[0009] As a further improvement of the present invention, the top ends of the adjacent two side surfaces of the beam-column body are fixedly connected with reinforcing angle steels by bolts, one of the reinforcing angle steels is located at the bottom end of the beam, and the other reinforcing angle steel is located at the bottom end of the supporting steel.

[0010] By such arrangement, the structural stability of the support is greatly improved by the arrangement of the reinforcing angle steel.

[0011] As a further improvement of the present invention, a reinforcing rib is fixedly connected to the side surface of the reinforcing angle steel.

[0012] By setting it up in this way, the structural stability of the reinforced angle steel during support is improved As a further improvement of the present invention, a plug hole is provided on one side surface of the cross-beam clamping column, and a second sleeve groove is provided on the other side surface of the cross-beam clamping column. The second sleeve groove is consistent with the model specification of the steel bar clamp, and the bottom end of the cross-beam clamping column is fitted with the inner bottom of the cross beam.

[0013] By such arrangement, when the prefabricated floor slab is assembled between two cross beams, the sleeve groove 2 on the cross bracing beam clamping column will be sleeved on the surface of the steel bar clamping head, thus completing the installation of the prefabricated floor slab.

[0014] As a further improvement of the present invention, a first pre-embedded steel bar hole is provided on the groove wall of the groove, and a second pre-embedded steel bar hole is provided on the side of the cross bracing beam clamping column, and the second pre-embedded steel bar hole corresponds to the position of the first pre-embedded steel bar hole.

[0015] Through such an arrangement, after the positions of the second embedded steel bar hole and the first embedded steel bar hole are aligned, it is convenient to insert the reinforcing steel bars into the second embedded steel bar hole and the first embedded steel bar hole, which not only improves the structural stability of the prefabricated floor slab and the cross bracing beam column, but also can enhance the bearing capacity of the prefabricated floor slab.

[0016] As a further improvement of the present invention, the edges on both sides of the prefabricated floor slab are provided with a plurality of through holes, and plugs are slidably inserted into the inside of the through holes. The plugs match the model specifications of the limiting holes, and the plug holes match the model specifications of the plugs.

[0017] Through such an arrangement, the plug in the middle of the prefabricated floor slab will be inserted into the inside of the limiting hole, further fixing the embedded channel steel and the prefabricated floor slab. The plugs inserted at both ends of the prefabricated floor slab will pass through the limiting holes at both ends of the embedded channel steel and then penetrate the insertion holes, thereby further fixing the cross bracing beam column to the prefabricated floor slab.

[0018] As a further improvement of the present invention, the edge of the embedded channel steel is provided with a weld.

[0019] With such an arrangement, after multiple groups of prefabricated floor slabs are assembled, adjacent prefabricated floor slabs are closely attached to each other through embedded channel steels, and are welded at the weld seams using a welding torch, so that the multiple prefabricated floor slabs form a whole.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. The auxiliary connection device of the assembled concrete beam column and the floor slab is provided with a cross bracing beam clamp and a prefabricated floor slab. When one end of the cross bracing beam clamp is clamped into the groove of the end of the prefabricated floor slab, the other end of the cross bracing beam clamp can be overlapped on the beam, and the construction of the prefabricated floor slab can be completed. After the cross bracing beam clamp is assembled, the embedded channel steel is embedded in both sides of the prefabricated floor slab. At this time, the two ends of the embedded channel steel will be respectively sleeved on the end of the cross bracing beam clamp, so that the cross bracing beam clamp can be fixed inside the groove. After the plug is inserted into the inside of the perforation one, the plug in the middle of the prefabricated floor slab will be inserted into the limit hole. Inside, the embedded channel steel and the prefabricated floor slab are further fixed. The bolts inserted at both ends of the prefabricated floor slab will pass through the insertion holes after passing through the limit holes at both ends of the embedded channel steel, thereby further fixing the cross bracing beam column to the prefabricated floor slab. At this time, after multiple groups of prefabricated floor slabs are assembled, adjacent prefabricated floor slabs are tightly attached to each other through the embedded channel steel, and are welded from the welds with a welding gun, so that the multiple prefabricated floor slabs form a whole. Finally, the surface can be leveled with concrete. The manufactured prefabricated floor slab can be completely prefabricated as a whole, which not only greatly improves the construction efficiency, but also improves the structural stability between the floor slabs.

[0021] 2. This auxiliary connection device for prefabricated concrete beams, columns and floor slabs is provided with a beam-column body, supporting steel and a crossbeam. During assembly, after the crossbeam is supported by the beam-column body, the clamping joints at both ends of the supporting steel are overlapped at the two ends of the crossbeam. At this time, the sleeve groove on the clamping joint will be sleeved on the steel bar clamps at both ends of the crossbeam. At this time, a rectangle is formed between the supporting steel and the crossbeam, and the beam-column body is used to support it. At the same time, the setting of the strengthening angle steel greatly improves the structural stability of the support, and is easy to assemble, greatly improves the construction efficiency, and significantly reduces the construction cost. The design connection is reliable, the seismic performance is good, the construction efficiency is improved, and the pollution of the construction to the environment is reduced.

After the cross beam 300 is supported by the beam-column body 100, the clamping joints 401 at both ends of the supporting steel 400 are overlapped on the two ends of the cross beam 300. At this time, the sleeve groove 402 on the clamping joint 401 will be sleeved on the steel bar clamps 301 at both ends of the cross beam 300.

[0027] For further preference, see Figure 1 The top ends of the adjacent two side surfaces of the beam-column body 100 are fixedly connected with reinforcing angle steels 101 by bolts, wherein one reinforcing angle steel 101 is located at the bottom end of the beam 300 , and the other reinforcing angle steel 101 is located at the bottom end of the supporting steel 400 .

[0028] For further preference, see Figure 1 The side of the reinforced angle steel 101 is fixedly connected with a reinforcing rib 102, which greatly improves the structural stability of the reinforced angle steel 101 during support.

[0029] For further preference, see Figure 2 , Figure 3 A plug hole 501 is provided on one side of the cross beam clamping column 500, and a sleeve groove 502 is provided on the other side of the cross beam clamping column 500. The sleeve groove 502 matches the model and specification of the steel bar clamping head 301, and the bottom end of the cross beam clamping column 500 fits the inner bottom of the cross beam 300. When the prefabricated floor 200 is assembled between the two cross beams 300, the sleeve groove 502 on the cross beam clamping column 500 will be sleeved on the surface of the steel bar clamping head 301, completing the installation of the prefabricated floor 200.

[0032] For further preference, see Figure 1 , Figure 3 , the edge of the embedded channel steel 600 is provided with a weld 602. After the multiple groups of prefabricated floor slabs 200 are assembled, the adjacent prefabricated floor slabs 200 are closely attached to each other through the embedded channel steel 600, and are welded at the weld 602 using a welding torch, so that the multiple prefabricated floor slabs 200 form a whole, and finally the surface can be flattened with concrete.

[0033] Working principle: When one end of the cross bracing beam clamping column 500 is clamped into the groove 203 at the end of the prefabricated floor 200, the other end of the cross bracing beam clamping column 500 can be overlapped on the cross beam 300, and the construction of the prefabricated floor 200 can be completed. After the cross bracing beam clamping column 500 is assembled, the embedded channel steel 600 is embedded on both sides of the prefabricated floor 200.

Thus, the cross bracing beam clamping column 500 can be fixed inside the groove 203, and after the plug 202 is inserted into the inside of the through hole 201, the plug 202 in the middle of the prefabricated floor 200 will be inserted into the inside of the limiting hole 601, and the embedded channel steel 600 and the prefabricated floor 200 will be further fixed. The plugs 202 inserted at both ends of the prefabricated floor 200 will pass through the insertion hole 501 after passing through the limiting holes 601 at both ends of the embedded channel steel 600, thereby fixing the cross bracing beam. The clamping column 500 is further fixed to the prefabricated floor slab 200. At this time, after multiple groups of prefabricated floor slabs 200 are assembled, adjacent prefabricated floor slabs 200 are tightly attached to each other through the embedded channel steel 600, and are welded from the weld 602 using a welding gun, so that the multiple prefabricated floor slabs 200 form a whole, and finally the surface can be flattened with concrete. During assembly, after the cross beam 300 is supported by the beam-column body 100, the clamping joints 401 at both ends of the supporting steel 400 are overlapped at both ends of the cross beam 300. At this time, the sleeve groove 402 on the clamping joint 401 will be sleeved on the steel bar clamps 301 at both ends of the cross beam 300. At this time, a rectangle is formed between the supporting steel 400 and the cross beam 300, and the beam-column body 100 is used to support it. At the same time, the setting of the strengthening angle steel 101 greatly improves the structural stability of the support, and is easy to assemble, which greatly improves the construction efficiency and significantly reduces the construction cost.
