Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, and in particular to a concrete prefabricated quick connector. BACKGROUND

[0002] In the current building engineering, the concrete prefabricated pipe pile is widely used in foundation treatment engineering due to its high strength, short construction period, low cost and other advantages. However, the existing prefabricated pipe pile connection method still has obvious defects: the traditional connection mostly adopts welding connection or flange bolt connection, the welding connection needs professional welder to operate on site, is greatly affected by the construction environment (such as the welding quality is difficult to guarantee in rainy days or low temperature environment), and needs to wait for cooling after welding, which seriously restricts the construction progress; the flange bolt connection needs to tighten the bolts one by one manually, which is tedious and time-consuming.

[0003] In view of the above technical defects, a solution is proposed, which drives the plug-in and the plug-in sleeve to move in opposite directions, and when the plug-in is inserted into the plug-in sleeve, the connection and fixation of the first pipe pile and the second pipe pile are completed, replacing the existing prefabricated pipe pile connection method, which has the advantages of simple operation, time and labor saving, and is not limited by the construction site and the construction environment, greatly improving the construction progress. SUMMARY

[0004] The purpose of the present application is to provide a concrete prefabricated quick connector to solve the above-mentioned problems.

[0005] The purpose of the present application can be realized by the following technical scheme: a concrete prefabricated quick connector, comprising:

[0006] The female connector assembly comprises a first installation hole opened at one end of the first pipe pile, a first connecting sleeve installed inside the first installation hole, and a plug-in installed inside the first connecting sleeve.

[0007] The male connector assembly comprises a second installation hole opened at one end of the second pipe pile, a second connecting sleeve installed inside the second installation hole, and a plug-in sleeve installed inside the second connecting sleeve.

[0008] Preferably, the first connecting sleeve inner wall is provided with a first inner thread, the plug-in outer wall is provided with a first outer thread, and the plug-in is threadedly connected inside the first connecting sleeve by matching the first outer thread with the first inner thread.

[0009] Preferably, the second connecting sleeve inner wall is provided with a second inner thread, the plug-in sleeve outer wall is provided with a second outer thread, and the plug-in sleeve is threadedly connected inside the second connecting sleeve by matching the second outer thread with the second inner thread.

[0010] Preferably, the snap assembly comprises a taper movably arranged inside the second connecting sleeve, a snap strip fixed to the inner wall of the taper, and a snap groove arranged on the outer wall of the insert.

[0011] Preferably, the taper is fixed with a spring at one end.

[0012] Preferably, the end of the spring away from the taper is fixed to the inner wall of the second connecting sleeve.

[0013] Advantages of the present application:

[0014] 1. First, the first connecting sleeve is installed and fixed into the first mounting hole of the first pipe pile, and then the insert is threadedly connected to the inside of the first connecting sleeve under the cooperation of the first outer thread and the first inner thread. Similarly, the second connecting sleeve is installed and fixed into the second mounting hole of the second pipe pile, and then the insert sleeve is threadedly connected to the inside of the second connecting sleeve under the cooperation of the second outer thread and the second inner thread. Then, the insert and the insert sleeve are driven to move in opposite directions. When the insert is inserted into the insert sleeve, the connection and fixation of the first pipe pile and the second pipe pile are completed. Compared with the prior art, the present application replaces the connection mode of the existing prefabricated pipe pile, has the advantages of simple operation, time and labor saving, and is not limited by the construction site and the construction environment, thereby greatly improving the construction progress.

[0015] 2. When the insert is inserted into the insert sleeve, the insert will extrude the taper, and the spring will be compressed and contracted. With the deepening of the insert, the snap strip on the inner wall of the taper will be snapped into the snap groove on the outer wall of the insert, thereby completing the locking of the insert. Since the first pipe pile and the second pipe pile are connected and adhered, the first pipe pile and the second pipe pile cannot move in opposite directions. Therefore, only the tensile property of the first pipe pile and the second pipe pile needs to be considered. When the first pipe pile and the second pipe pile are subjected to tension, the insert will drive the taper to move leftward. At this time, the taper will be limited by the second connecting sleeve, so that the second connecting sleeve cannot move leftward, thereby improving the connection stability of the first pipe pile and the second pipe pile.

[0024] First, the first connecting sleeve 103 is installed and fixed into the first mounting hole 102 of the first pipe pile 101, and then the insert 104 is screwed into the inside of the first connecting sleeve 103 under the cooperation of the first outer thread and the first inner thread. Similarly, the second connecting sleeve 203 is installed and fixed into the second mounting hole 202 of the second pipe pile 201, and then the insert sleeve 204 is screwed into the inside of the second connecting sleeve 203 under the cooperation of the second outer thread and the second inner thread. Then, the insert 104 and the insert sleeve 204 are driven to move in opposite directions. When the insert 104 is inserted into the insert sleeve 204, the connection and fixation of the first pipe pile 101 and the second pipe pile 201 are completed. Compared with the prior art, the present application replaces the connection method of the existing prefabricated pipe pile, has the advantages of simple operation, time and labor saving, and is not limited by the construction site and the construction environment, greatly improving the construction progress.

[0025] Embodiment two: please refer to Figs. 1-3 As shown in the drawings, the present embodiment is a kind of prefabricated concrete fast connecting piece, further comprising clamping assembly 300, clamping assembly 300 includes the taper piece 302 movably arranged in the inside of second connecting sleeve 203, the clamping strip 303 fixed in the inner wall of taper piece 302, the clamping groove 301 opened in the outer wall of insert 104, one end of taper piece 302 is fixed with spring 304, the end of spring 304 away from taper piece 302 is fixed with the inner wall of second connecting sleeve 203;

[0026] When the insert 104 is inserted into the insert sleeve 204, the insert 104 will extrude the taper piece 302, and the spring 304 will be compressed and contracted.

Since the first pipe pile 101 and the second pipe pile 201 are connected and adhered, the first pipe pile 101 and the second pipe pile 201 cannot move in opposite directions, so only the tensile properties of the first pipe pile 101 and the second pipe pile 201 need to be considered. When the first pipe pile 101 and the second pipe pile 201 are subjected to tension, the insert 104 will move left with the taper piece 302, and the taper piece 302 will be limited by the second connecting sleeve 203 at this time, so that the second connecting sleeve 203 cannot move left, thereby improving the connection stability of the first pipe pile 101 and the second pipe pile 201.

[0027] In combination of Embodiment One and Embodiment Two, on one hand, the plug-in 104 and the plug sleeve 204 are driven to move oppositely, and after the plug-in 104 is inserted into the plug sleeve 204, the connection and fixation of the first pipe pile 101 and the second pipe pile 201 are completed, which replaces the existing connection mode of the prefabricated pipe pile, has the advantages of simple operation, time and labor saving, and is not limited by the construction site and the construction environment, and greatly improves the construction progress; on the other hand, when the first pipe pile 101 and the second pipe pile 201 are subjected to tension, the plug-in 104 drives the conical part 302 to move left, and at this time, the conical part 302 is limited by the second connecting sleeve 203, so that the second connecting sleeve 203 cannot move left, thereby improving the connection stability of the first pipe pile 101 and the second pipe pile 201.

[0028] The above is only an example and description of the structure of the present application, and those skilled in the art can make various modifications or supplements or use similar ways to replace the described specific embodiments, as long as they do not deviate from the structure of the present application or exceed the scope defined by the present claims, which shall belong to the protection scope of the present application.
