It is usually pre -buried in concrete foundation or component, after the concrete solidification, bolt is firmly fixed in structure, is used for subsequent equipment installation or component connection.

[0003] The existing pre -buried bolt fixed structure still has certain deficiency in the actual use process: some large components (for example high pole lamp) foundation construction, need pre -buried bolt, and the interval and position of positioning bolt are crucial, however, when pre -buried bolt through the manual placement of worker in the prior art, error is inevitable, thereby the position of the final embedding bolt is offset, based on the technical deficiency of the prior art, the utility model designs a pre -buried bolt fixed structure. UTILITY MODEL CONTENT

[0004] In view of the deficiency of the prior art, the utility model provides a pre -buried bolt fixed structure, has the advantages of positioning the distance between bolts in advance, avoiding error in subsequent embedding position.

[0005] The utility model provides following technical scheme: a pre -buried bolt fixed structure, including metal positioning board, the inside of metal positioning board is seted up with the positioning hole, a group of pre -buried holes are seted up around the positioning hole, the inside of a group of pre -buried holes is placed with bolt, the outer surface of bolt is equipped with fixed nut with screw thread, the inside of metal positioning board is provided with slide rod, the top both sides of slide rod are fixedly installed with alignment structure, two alignment structures include first support plate, two second support plates, the inside of one second support plate is equipped with threaded rod with screw thread, one end of threaded rod is rotatably connected with first support plate, the other end of threaded rod is fixedly installed with steering handle, the inside of another second support plate is fixedly installed with first spring, and one end of another first spring is fixedly connected with first support plate.

[0006] As a preferred technical scheme of the utility model, the bottom of two second support plates is fixedly installed with clamping plate, and the outer surface of two clamping plates is provided with fixed structure, and two fixed structures include two fixed shafts and two side plates.

[0007] As a preferred technical scheme of the utility model, the outer surface of two fixed shafts is rotatably installed with push rod, and the fixed installation of two push rods is provided with connecting rod between two push rods.

[0008] As a preferred embodiment of this utility model, a second spring is fixedly installed on one side of each of the two side plates, and one end of each second spring is fixedly connected to a lever.

[0009] As a preferred embodiment of this utility model, handles are fixedly installed on both sides of the outer surface of the metal positioning plate.

[0010] As a preferred embodiment of this utility model, the metal positioning plate has a sliding groove inside.

[0011] In a preferred embodiment of this invention, the sliding groove is slidably connected to the sliding rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This pre-embedded bolt fixing structure, through positioning holes, pre-embedded holes, and alignment structures, allows for the pre-embedding process by sequentially inserting a group of bolts into the pre-embedded holes and fixing them with fixing nuts. At this time, the spacing between each bolt is fixed. When the device is placed on top of the steel frame, rotating the handle causes the threaded rod to rotate and push the first support plate forward. This allows the first support plate to move the metal positioning plate on the outer surface of the sliding rod. The process stops when the positioning hole is aligned with the center point of the steel frame. At this point, the position of the bolts will not change during the pouring process. After the pouring is completed, the fixing nuts are unscrewed and the device is removed. This achieves the purpose of pre-positioning the position and spacing of the bolts and placing them with the center point of the steel frame as a reference, avoiding errors in the subsequent embedding position.

[0014] 2. This type of pre-embedded bolt fixing structure, through the sliding rod and fixing structure, when the device is placed on top of the steel frame, by pushing the connecting rod downward, the second spring is stretched, which drives the lever to unfold, and the two clamping plates can be fixed on both sides of the steel frame, thereby improving the stability of the device during the subsequent pouring process.
