Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to an assembled concrete structure. Background Art

[0002] Prefabricated concrete buildings refer to concrete structures designed and constructed mainly with factory-produced prefabricated reinforced concrete components through on-site assembly. Compared with traditional buildings, prefabricated concrete buildings have the advantages of ensuring project quality, reducing safety hazards, improving production efficiency, reducing labor costs, saving energy and protecting the environment, and extending the life of the building.

[0003] The prior art publication number is CN217811891U, which describes an assembled concrete structure that optimizes precast concrete structures to a certain extent, reducing manufacturing costs and the difficulty of vertical connection construction. The assembled concrete structure provided by the utility model includes an assembly body and a first steel bar. One end of the assembly body is a butt joint, and a relief recess is formed on the butt joint. The first steel bar is arranged corresponding to the relief recess, extends along the height direction of the assembly body, and is embedded in the assembly body. Both ends of the first steel bar protrude from the assembly body, and one end of the first steel bar is located in the relief recess.

[0004] The connection structure reserved for concrete components in the prior art is inconvenient to install, and requires secondary fixation with concrete after assembly, which affects the construction speed. At the same time, the size of the connection area is smaller than the size of the main body, resulting in insufficient bearing strength of the connection area, which is prone to deformation when bearing load or pressure in the later stage, threatening the safety of the main body. In addition, the area fastened by bolts is prone to loosening and falling off when vibration occurs in the later stage, thereby affecting the overall connection strength and stability of use. There are certain risks in use, and the overall use effect is not very good.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] (1) Technical problems solved

[0007] In view of the deficiencies in the prior art, the present invention provides an assembled concrete structure having the advantages of strong connection stability, large connection bearing surface, and high use strength, thereby solving the problems in the above-mentioned background technology.

[0008] (2) Technical solution

[0009] In order to achieve the above advantages of strong connection stability, large connection bearing surface and high use strength, the specific technical solutions adopted by the present invention are as follows:

[0010] The assembled concrete structure includes concrete columns and concrete beams. Several groups of docking grooves are symmetrically provided on both sides of the surface of the concrete columns. A limiting groove is provided above the docking groove on the surface of the concrete column. A fastening bolt is threadedly connected to the inner position of the limiting groove. A blocking plate is clamped at the top position of the inner position of the limiting groove. Limiting components are symmetrically and staggeredly installed at both ends of the blocking plate inside the concrete column. A movable plate is slidably connected to the inner position of the limiting component. A limiting rod is installed at the top position of the movable plate, and the limiting rod passes through both sides of the blocking plate and is plugged into the concrete column. A spring is installed at the bottom position of the movable plate.

[0011] Furthermore, a concrete beam is clamped in the internal position of the docking groove, and a docking protrusion is integrally formed on the surface of one end of the concrete beam.

[0012] Furthermore, a sealing block for filling is provided inside the docking groove.

[0013] Furthermore, thread grooves for fastening bolt connections are provided on the surface of the limiting groove, the surface of the concrete beam and the surface of the blocking block.

[0014] Furthermore, the length of the limiting rod is greater than the thickness of both ends of the blocking plate.

[0015] Furthermore, a hole for inserting a limiting rod is opened inside the concrete column.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides an assembled concrete structure with the following beneficial effects:

[0018] (1) The utility model adopts a blocking plate. After the concrete beam is inserted, the concrete beam and the concrete column can be effectively connected by the fastening bolts inside the limiting groove. After the fastening screw is inserted, the top of the limiting groove can be locked by inserting the blocking plate into the slot above the limiting groove. In this way, even if the bolt moves during subsequent vibrations, it will not fall off due to the obstruction of the blocking plate, thereby ensuring the stability and strength of the connection structure. The limiting rods used for limiting on the surface of the blocking plate are also directly inserted into the concrete column from both ends. In this way, the falling off of the fastening bolts caused by the falling off of the limiting rods due to the deformation of the spring can be avoided, thereby ensuring the overall strength of use and having the advantage of strong connection stability.

[0019] (2) The present invention adopts a docking groove and a blocking block. In actual use, the concrete beam can be limited by clamping the docking protrusion on the surface of the concrete beam with the docking groove on the surface of the concrete column. In addition, a notch is provided at the end of the docking groove to accommodate the concrete beam. Therefore, the connection area between the concrete beam and the concrete column is increased during connection, so that the subsequent force acting on the concrete beam can be better dispersed, thereby improving the connection strength of the structure. The unused docking groove on the surface of the concrete column can be filled with a blocking block, which effectively avoids the problem of a decrease in bearing capacity due to vacancies on the surface of the structure, improves the overall use strength, and has the advantages of a large connection bearing surface and high use strength.

[0027] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0028] According to an embodiment of the present invention, a prefabricated concrete structure is provided.

[0029] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-4 As shown, the assembled concrete structure according to the embodiment of the present invention includes a concrete column 1 and a concrete beam 4. Several groups of docking grooves 2 are symmetrically provided on both sides of the surface of the concrete column 1. A limiting groove 8 is provided above the docking groove 2 on the surface of the concrete column 1. A fastening bolt 7 is threadedly connected to the inner position of the limiting groove 8. A blocking plate 6 is clamped at the top position of the inner part of the limiting groove 8. The two ends of the blocking plate 6 are symmetrically and staggeredly installed at the inner position of the concrete column 1. A movable plate 11 is slidably connected to the inner position of the limiting component 3. A limiting rod 12 is installed at the top position of the movable plate 11, and the limiting rod 12 passes through both sides of the blocking plate 6 and is plugged into the concrete column 1. A spring 10 is installed at the bottom position of the movable plate 11.

[0030] In one embodiment, a concrete beam 4 is clamped in the internal position of the docking groove 2, and a docking protrusion 5 is integrally formed on the surface of one end of the concrete beam 4. The docking protrusion 5 is provided to facilitate the pre-fixation of the concrete beam 4, but the main part of the concrete beam 4 actually plays the role of load-bearing and fixing. This can increase the area of ​​the connection and thus better bear the load.

[0031] In one embodiment, a blocking block 9 for filling is provided inside the docking groove 2. The blocking block 9 is provided to block the gaps on the surface of the concrete column 1, ensure the fullness of the structure, and reduce the existence of gaps. Its structure is the same as the slot structure of the docking groove 2.

[0032] In one embodiment, threaded grooves for connection with fastening bolts 7 are provided on the surface of the limiting groove 8, the surface of the concrete beam 4 and the surface of the blocking block 9. The threaded grooves on the surface of the concrete beam 4 are intended to enable the fastening bolts 7 to be directly connected to the main body, while avoiding connection with the docking protrusion 5, which would reduce the connection strength.

[0033] In one embodiment, the length of the limiting rod 12 is greater than the thickness of both ends of the blocking plate 6. The size of the limiting rod 12 is set to ensure that there is sufficient margin to prevent the blocking plate 6 from falling off. During installation, the limiting rod 12 can be lifted up by a card first, and then the blocking plate 6 can be inserted into it. Then, the limiting rod 12 can be released by pulling out the card. The specific method can be adjusted according to needs.

[0034] In one embodiment, a hole is provided inside the concrete column 1 for inserting the limiting rod 12 . The hole is provided to fix the limiting rod 12 , thereby ensuring the stability of the blocking plate 6 .

[0035] Working principle: In actual use, the concrete beam 4 can be limited by clamping the surface docking protrusion 5 of the concrete beam 4 with the docking groove 2 on the surface of the concrete column 1, and the end of the docking groove 2 is provided with a notch for accommodating the concrete beam 4. Therefore, when connecting, the connection area between the concrete beam 4 and the concrete column 1 is increased, so that the subsequent force acting on the concrete beam 4 can be better dispersed, thereby improving the connection strength of the structure. After the concrete beam 4 is inserted, the concrete beam 4 and the concrete column 1 can be effectively connected through the fastening bolts 7 inside the limiting groove 8, and after the fastening screw is inserted, the top of the limiting groove 8 can be fixed by inserting the blocking plate 6 into the slot above the limiting groove 8. The locking is performed so that even if the bolt moves during subsequent vibrations, it will not fall off due to the obstruction of the blocking plate 6, thereby ensuring the stability and usability of the connection structure. The limiting rods 12 used for limiting the position on the surface of the blocking plate 6 are also directly inserted into the concrete column 1 from both ends. This can avoid the falling off of the limiting rods 12 caused by the deformation of the spring 10, which may lead to the falling off of the fastening bolts 7, thereby ensuring the overall usability. The unused docking grooves 2 on the surface of the concrete column 1 can be filled with the blocking blocks 9, which effectively avoids the problem of reduced bearing capacity due to gaps on the surface of the structure, thereby improving the overall usability. The device as a whole has the advantages of strong connection stability, large connection bearing surface and high usability.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.
