Because the construction needs in the building structure work progress, need install on the main structure body if the tower crane adheres to, operation platform, support adheres to interim construction facilities such as. In this case, the steel plates need to be embedded as an acting point during the concrete casting construction of the main structure. The construction method has the following defects: (1) after the embedded steel plate is machined and formed, the direction of a hook at the end part of an anchor bar cannot be adjusted, and the installation of the structural steel bar cannot be smoothly finished due to the influence of a steel bar gap after the structural steel bar is constructed during installation; (2) the embedded steel plate needs to be parallel to the outer surface of the structure, and the installation precision of the embedded steel plate is difficult to control during construction; (3) the embedded steel plates need to be removed together when the temporary structure is removed, and the embedded steel plates are located on the protective layer and firmly anchored by the anchor bars, so that the operation difficulty is high; (4) after the embedded steel plate is removed, pits are left on the outer surface of the structure, concrete, mortar and the like are needed for repairing, and because the age difference with the original structure concrete is too large and the concrete cannot be maintained, shrinkage cracks, color difference and the like are inevitable, the appearance quality is poor, and the embedded steel plate is easy to fall off. Therefore, an embedded steel plate convenient to disassemble and assemble on a concrete structure is needed to solve the problems that the traditional embedded part is difficult to assemble and disassemble, the appearance quality of the disassembled structure is difficult to effectively ensure and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provide an embedded steel plate convenient to disassemble and assemble on a concrete structure, so as to solve the problems that the traditional embedded part is difficult to assemble and disassemble, the appearance quality of the structure after disassembly is difficult to effectively ensure and the like.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
an embedded steel plate convenient to disassemble and assemble on a concrete structure comprises the concrete structure, wherein embedded bolts facing one side of an installation surface are embedded in the concrete structure, and a connecting sleeve is embedded in the installation surface of the concrete structure; the inner end of the connecting sleeve is in threaded connection with the threaded section of the embedded bolt, and the outer end of the connecting sleeve is in threaded connection with a screw rod; the screw is sleeved with a steel plate with a pre-opened hole, and the steel plate is provided with a nut fixedly matched with the screw; an additional structure is fixedly arranged on the steel plate.
Furthermore, the steel plate is provided with pre-opened holes according to the distribution of the connecting sleeves, and the opened holes are oval.
Further, the outer end of the screw rod is provided with a hexagonal head.
Furthermore, the threaded section of the embedded bolt is screwed into one half of the connecting sleeve, and the screw is screwed into the other half of the connecting sleeve.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, the embedded bolt and the connecting sleeve are combined to form the embedded part, so that the traditional embedded steel plate is replaced, the invasion to the main body structure is greatly reduced, and the embedding is convenient. The pre-opening hole on the steel plate is oval, when the embedded angle deviation of a part of embedded bolts, the steel plate can be fixed firstly, then the screw rod is screwed into the connecting sleeve thread, the nut is screwed up to fix the steel plate at last, and the problem that the steel plate cannot be installed when the angle deviation directions of the embedded bolts are inconsistent can be effectively avoided. The end part of the screw rod is provided with a hexagonal head, so that the screw rod is convenient to screw, and the steel plate is disassembled with time and labor saving. The steel plate has little influence on the appearance of the structure after being dismantled, and has no hidden quality trouble after being repaired. The steel plate and the additional structure after being disassembled can be reused, and construction cost is saved.
