Preferably, the splint subassembly includes a splint and a plurality of circular steel pipes, the steel pipe is evenly arranged the same one side of splint, splint with steel pipe fixed connection.

Preferably, the clamping plate is of a structure like a Chinese character ri, and the four corners of the clamping plate are respectively provided with a polygonal connecting end.

Preferably, the connecting end is of an octagonal structure, a through hole is formed in the center of the connecting end, an edge is arranged at the center far away from the clamping plate, and the connecting bolt penetrates through the through hole.

Preferably, the inner diameter of the steel pipe is larger than or equal to the outer diameter of the PVC pipe, and two ends of the PVC pipe penetrate through the steel pipe and are abutted against the clamping plate.

Preferably, both ends of the connecting bolt are provided with threads, and the length of the threads is greater than or equal to 100mm and less than or equal to 175 mm.

Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:

the fixing device of the embedded bolt sleeve of the tower crane attachment support, the embedded connecting bolt and the PVC pipe improve the installation efficiency and the installation precision of the attachment device; the installation is carried out without a wall-through punching mode, so that the dust pollution is reduced; simple structure, reduced cost and improved efficiency.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example 1

In the attached drawings 1 to 4, the fixing device for the embedded bolt sleeve of the tower crane attached support comprises two clamping plate assemblies, a plurality of PVC pipes 2 and a plurality of connecting bolts 4.

2 both ends of PVC pipe are through splint subassembly crimping, and connecting bolt 4 wears to establish in PVC pipe 2, and splint subassembly compresses tightly through nut 5 with connecting bolt 4.

The splint subassembly includes a splint 1 and a plurality of circular shape steel pipe 3, and steel pipe 3 evenly arranges in splint 1 same one side, and splint 1 and 3 fixed connection of steel pipe, preferred welding mode are connected. The splint 1 is in a structure like a Chinese character 'ri', polygonal connecting ends 11 are respectively arranged at four corners of the splint 1, the splint 1 is respectively provided with a connecting end 11 at the connecting position between two middle parts of the structure like the Chinese character 'ri', and the number of the connecting ends 11 is 6. The connecting end 11 is an octagonal structure, a through hole 112 is formed in the center of the connecting end 11, an edge 111 is formed in the center of the connecting end 11 far away from the clamping plate 1, and the connecting bolt 4 penetrates through the through hole 112.

The inner diameter of the steel pipe 3 is larger than or equal to the outer diameter of the PVC pipe 2. The both ends department of PVC pipe 2 wears to establish in steel pipe 3, PVC pipe 2 and splint 1 butt. The connecting bolt 4 presses the PVC pipe 2 between the pressing plates 1 by means of nuts 5 screwed at both ends thereof.

The connecting bolt 4 is provided at both ends with threads 41. The length of the thread 41 is more than or equal to 100mm and less than or equal to 175mm, so that the connection with an external connecting piece is convenient.

Example 2

In the attached drawings 5 to 8, only the clamping plate 1 of the herringbone structure is positioned at the position of the two middle connecting positions of the herringbone structure and is not provided with the connecting ends 11, the number of the connecting ends 11 is 4, and the rest structures are the same as those of the embodiment 1.

Selecting a PVC pipe 2 with a proper inner diameter according to the size of the connecting bolt 4 of the attachment support, fixing the PVC pipe 2 in a wall body at the position where the attachment support needs to be installed after the building wall body or the upright post is bound with steel bars and before concrete is poured, opening a hole matched with the outer diameter of the PVC pipe 2 on a template at the corresponding position of the pre-embedded PVC pipe 2, and fixing the PVC pipe 2 in the middle of the template through two specially-made clamping plates 1 by using the connecting bolt 4, namely completing the installation of the whole fixing device. And in the later stage, the PVC pipe 2 is poured in the wall body, after the concrete strength reaches the required demoulding, the clamping plate 1 is disassembled, and the embedding work of the attached support bolt sleeve is completed.

The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
