Description

Technical Field

[0001] The present invention relates to the technical field of embedded channels, and specifically relates to a detachable embedded channel and a disassembly method thereof. Background Art

[0002] In recent years, with the development of society, the utility tunnel, as a concrete structure tunnel space integrating various engineering pipelines such as electric power, communication, gas, heating, water supply and drainage, has developed rapidly. Since the utility tunnel bears some "lifelines" of the city, strict requirements are imposed on the embedded channels in the utility tunnel during the construction of urban subway roads. The embedded channels in the utility tunnel are buried in concrete and are fixing parts for fixing and hanging the supports of various pipelines, and their applications in urban subway roads are also becoming more and more extensive.

[0003] Embedded channels can be used as supports on cast-in-place and precast concrete components, and the stiffening ribs on the side of the channel have a locking function. The embedded channels currently used in fields such as high-speed railways, subways, and utility tunnels are all welded or riveted to the anchor rods and then embedded in concrete, resulting in the inconvenience of replacing the embedded channels. When the embedded channels are damaged during use, they cannot be repaired; and this kind of embedded channel is generally a rigid connection, that is, directly embedded in concrete, and cannot be disassembled and relocated, which is not convenient for re-construction. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a detachable embedded channel and a disassembly method thereof to solve the problems that when the embedded channel is damaged during use, it cannot be repaired; and this kind of embedded channel is generally a rigid connection, that is, directly embedded in concrete, and cannot be disassembled and relocated, which is not convenient for re-construction.

[0012] Through the above technical solution, by using the elastic force generated by the driving spring, the fastening property of the clamping block clamped into the limiting groove is improved, and at the same time, the connection strength between the sleeve and the channel body is improved.

[0013] The present invention provides a preferred technical solution. First locking holes for inserting the locking rod are penetrated through the channel bodies on both sides of the opening groove. A second locking hole for the locking rod to be inserted through the first locking hole and then clamped is penetrated through the T-shaped connector.

[0014] Through the above technical solution, by the setting of the first locking hole, the second locking hole and the locking rod in cooperation, the connection strength between the T-shaped connector and the channel body is improved.

[0015] The present invention provides a preferred technical solution. Limiting grooves for inserting the clamping blocks are provided on both inner side walls of the fastening groove. The limiting grooves communicate with the fastening groove.

[0016] Through the above technical solution, by the setting of the limiting groove and the clamping block, the connection strength between the sleeve and the channel body is improved.

[0017] The present invention also provides a disassembly method for a detachable embedded channel, including the following steps:

[0018] S1. First, embed the sleeve in the concrete wall;

[0019] S2. Then, pinch the connecting plate so that the clamping block retracts into the clamping groove. Insert the docking rod on the channel body into the docking groove of the sleeve, and at the same time, the fastening column is clamped into the fastening groove accordingly;

[0022] S5. Sleeve the mounting plate onto the connecting threaded column, so that the locking rod on the mounting plate is inserted into the connected first locking hole and the second locking hole for fixing.

[0023] S6. Finally, screw the connecting nut onto the connecting threaded column to fix it, and the installation is completed.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention realizes the detachable installation and fixation of the channel body on the concrete wall. When the channel body is damaged or needs to be disassembled for re-construction, it is only necessary to pinch the connecting plate to make the clamping block disconnect from the limit groove, so as to realize the disassembly between the channel body and the sleeve. The installation and disassembly are convenient and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
