Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete components, and more specifically, to a combined prefabricated concrete component. Background Art

[0002] Concrete is a general term for composite materials that are made of gel material, aggregate and water in appropriate proportions and then hardened after a certain period of time. It is the most widely used artificial civil construction material in the world. In municipal engineering, concrete is currently often used to make prefabricated components, which are then assembled to form a guardrail isolation structure.

[0003] After searching, the existing patent (publication number: CN219431155U) discloses a combined concrete precast component, which, when in use, can be combined and connected quickly by means of a limit assembly in conjunction with the plug-in hole of a connecting plate, thereby ensuring the tightness of the connection between two adjacent component bodies and preventing the combined components from being separated. At the same time, the combined setting can greatly reduce the volume of a single component and facilitate transportation. However, in the process of realizing the utility model, the inventor found that the prior art has the following problems: when the existing combined concrete precast components are connected and used, it is necessary to stack the two precast components, align the connecting plate with the plug-in hole, and then translate one precast component so that the connecting plate can be inserted into the plug-in hole to achieve connection. In this operating state, due to the heavy weight of the precast components, radially moving a precast component after alignment has the disadvantage of being difficult to operate, and it is difficult to meet the requirements of rapid installation.

[0004] Therefore, a combined precast concrete component is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a combined prefabricated concrete component to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined prefabricated concrete component, comprising a first component and a second component, wherein a telescopic connection assembly for connection is provided between the first component and the second component;

[0007] Insertion grooves are preset on the left and right sides of the first component, and a mounting shell is embedded in the interior of the second component. The interior of the mounting shell is rotatably connected with a positive and negative threaded screw, and both ends of the positive and negative threaded screw are symmetrically threaded with threaded sleeves. A telescopic plate is fixedly installed at one end of the threaded sleeve close to the side wall of the second component, and the telescopic plate is slidably connected to the inner wall of the mounting shell. A plug-in block is fixedly installed on the surface of the telescopic plate, and the plug-in block corresponds to the insertion groove, and a reinforcement component is arranged between the plug-in block and the insertion groove. An adjusting rod for driving the positive and negative threaded screw to rotate is vertically rotatably connected on the surface of the mounting shell, and a hexagonal nut is welded on the top of the adjusting rod, and the bottom end of the adjusting rod extends to the interior of the mounting shell and is fixedly installed with a worm, and a worm wheel is welded on the surface of the middle section of the positive and negative threaded screw, and the worm is meshed with the worm wheel.

[0008] Preferably, the number of the first components and the second components are both multiple, and the multiple first components and the multiple second components are arranged at intervals.

[0009] Preferably, an isolation tube is embedded inside the second component, and the isolation tube cover is arranged on the surface of the adjusting rod.

[0010] Preferably, the top, bottom, front and back of the plug-in block at one end away from the telescopic plate are all provided with inclined surfaces.

[0011] Preferably, the reinforcement assembly comprises a vertical slot opened on the surface of the first component, a reinforcement rod is slidably connected inside the vertical slot, and a circular hole for inserting the reinforcement rod is reserved on the surface of the plug-in block.

[0012] Preferably, the inner wall of the circular hole is conical, and the hole diameter at the top of the circular hole is larger than the hole diameter at the bottom.

[0013] Technical effects and advantages of the utility model:

[0014] 1. Compared with the prior art, when the combined prefabricated concrete component is used, the first component and the second component are neatly stacked. After stacking, a telescopic connection assembly is set, and the adjusting rod is rotated. The meshing of the worm and the worm wheel drives the positive and negative threaded screws to rotate, thereby driving the two threaded sleeves and the telescopic plate to move to the outside of the second component, so that the plug-in block extends out of the mounting shell and is correspondingly inserted into the insertion groove, thereby achieving the purpose of connecting the first component and the second component. During the connection, since there is no need to subsequently perform precise radial movement of the prefabricated components, the connection process has the advantages of simple operation and fast installation.

[0015] 2. Compared with the prior art, the combined precast concrete component, by providing a reinforcement assembly, can limit the plug-in block by inserting a reinforcement rod into the circular hole when connecting the first component and the second component, thereby performing secondary fixation on the first component and the second component, thereby improving the firmness and tightness of the connection between the first component and the second component. The circular hole has a conical structure with a larger top and a smaller bottom, thereby ensuring that the reinforcement rod can be quickly inserted into the circular hole. In the process of inserting the plug-in block into the insertion slot, the surface of the plug-in block is provided with an inclined surface, thereby ensuring that the plug-in block can be quickly inserted into the insertion slot, thereby further reducing the difficulty of connection and installation.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1-Figure 4 A combined prefabricated concrete component shown includes a first component 1 and a second component 2. The number of the first component 1 and the second component 2 are both multiple, and the multiple first components 1 and second components 2 are arranged at intervals.

[0023] A telescopic connection assembly for connection is provided between the first component 1 and the second component 2 .

[0024] Insertion grooves 3 are preset on the left and right sides of the first component 1, and a mounting shell 4 is pre-buried inside the second component 2. A forward and reverse threaded screw 5 is rotatably connected inside the mounting shell 4. Both ends of the forward and reverse threaded screw 5 are symmetrically threadedly connected with a threaded sleeve 6. A telescopic plate 7 is fixedly installed on one end of the threaded sleeve 6 close to the side wall of the second component 2. The telescopic plate 7 is slidably connected to the inner wall of the mounting shell 4, and a plug-in block 8 is fixedly installed on the surface of the telescopic plate 7, and the plug-in block 8 corresponds to the insertion groove 3.

[0025] The surface of the mounting shell 4 is vertically rotatably connected with an adjusting rod 9 for driving the forward and reverse threaded screw 5 to rotate.

[0026] An isolation tube 10 is embedded in the interior of the second component 2 , and the isolation tube 10 is covered on the surface of the adjustment rod 9 .

[0027] A hexagonal nut is welded to the top of the adjusting rod 9, and the bottom end of the adjusting rod 9 extends to the inside of the mounting shell 4 and is fixedly mounted with a worm 11. A worm wheel 12 is welded to the surface of the middle section of the forward and reverse thread screw 5, and the worm 11 is meshed with the worm wheel 12.

[0028] When the combined precast concrete component is in use, the first component 1 and the second component 2 are neatly stacked. After stacking, the adjusting rod 9 is rotated through the telescopic connection assembly, and the forward and reverse threaded screws 5 are driven to rotate based on the engagement of the worm 11 and the worm wheel 12, thereby driving the two threaded sleeves 6 and the telescopic plate 7 to move toward the outside of the second component 2, so that the plug-in block 8 extends out of the mounting shell 4 and is correspondingly inserted into the insertion groove 3, thereby achieving the purpose of connecting the first component 1 and the second component 2. When connecting, since there is no need to keep the plug-in block 8 facing the insertion groove 3 to perform precise radial movement of the second component 2, the connection process has the advantages of simple operation and fast installation.

[0029] Inclined surfaces 13 are formed on the top, bottom, front and back of the plug-in block 8 at one end away from the telescopic plate 7 .

[0030] Furthermore, during the process of inserting the plug-in block 8 into the insertion slot 3, the inclined surface 13 is provided on the surface of the plug-in block 8, which can ensure that the plug-in block 8 is quickly inserted into the insertion slot 3, further reducing the difficulty of connection and installation.

[0031] A reinforcement component is provided between the plug-in block 8 and the insertion slot 3 .

[0032] The reinforcement assembly includes a vertical slot opened on the surface of the first component 1, a reinforcement rod 14 is slidably connected inside the vertical slot, and a round hole 15 for the reinforcement rod 14 to be inserted is reserved on the surface of the plug-in block 8.

[0033] By means of the reinforcement assembly, when the first component 1 and the second component 2 are connected, the reinforcement rod 14 is inserted into the circular hole 15 to limit the plug-in block 8, so that the first component 1 and the second component 2 can be fixed for a second time, thereby improving the firmness and tightness of the connection between the first component 1 and the second component 2.

[0034] The inner wall of the circular hole 15 is conical, and the diameter of the top of the circular hole 15 is larger than that of the bottom.

[0035] Furthermore, since the circular hole 15 is a conical structure that is larger at the top and smaller at the bottom, it can ensure that the reinforcement rod 14 is quickly inserted into the circular hole 15 .

[0036] The working process of the utility model is as follows:

[0037] Firstly, when the combined precast concrete component is in use, the first component 1 and the second component 2 are neatly stacked. After stacking, the adjusting rod 9 is rotated through the telescopic connection assembly, and the forward and reverse threaded screws 5 are driven to rotate based on the engagement of the worm 11 and the worm wheel 12, thereby driving the two threaded sleeves 6 and the telescopic plate 7 to move toward the outside of the second component 2, so that the plug-in block 8 extends out of the mounting shell 4 and is correspondingly inserted into the insertion groove 3, thereby achieving the purpose of connecting the first component 1 and the second component 2. During the connection, since there is no need for subsequent precise radial movement of the precast components, the connection process has the advantages of simple operation and fast installation.

[0038] Furthermore, during the process of inserting the plug-in block 8 into the insertion slot 3, the inclined surface 13 is provided on the surface of the plug-in block 8, which can ensure that the plug-in block 8 is quickly inserted into the insertion slot 3, further reducing the difficulty of connection and installation.

[0039] On the other hand, by means of the reinforcement assembly, when the first component 1 and the second component 2 are connected, the reinforcing rod 14 is inserted into the circular hole 15 to limit the plug-in block 8, so that the first component 1 and the second component 2 can be fixed for a second time, thereby improving the firmness and tightness of the connection between the first component 1 and the second component 2. The circular hole 15 has a conical structure with a larger upper part and a smaller lower part, so that the reinforcing rod 14 can be quickly inserted into the circular hole 15.

[0040] This is how the modular precast concrete element works.
