[0023] The preferred embodiments of the utility model are described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the utility model, and are not intended to limit the protection scope of the utility model.

[0024] Example 1

[0025] As shown in Figures 1-3 , the prefabricated wallboard box type connecting piece with installation allowance of the embodiment includes wall body 1, anchor 2 is pre-set in wall body 1, pre-buried groove 3 is arranged between two adjacent wall bodies 1, the working end of anchor 2 is located on the side wall of pre-buried groove 3, connecting base body 4 is arranged in pre-buried groove 3, fastener 5 for cooperating with anchor 2 is arranged on connecting base body 4, pre-buried groove 3 is arranged on the side wall of wall body 1, two pre-buried grooves 3 form a storage groove for placing connecting base body 4 after two wall bodies are spliced, a gap is reserved between storage groove and connecting base body 4, which facilitates the installation of connecting base body 4 and fastener 5, connecting base body 4 is placed in storage groove, then fastener 5 is connected with anchor 2 after passing through connecting base body 4, the connection is completed, grouting sealing is carried out, the connection work of two wall bodies 1 is completed, the connection of two wall bodies 1 can be quickly completed through the box type connecting piece, the connection strength is strengthened, and the splicing efficiency is also improved.

[0026] Connecting base body 4 includes base plate 6 located at the bottom of pre-buried groove 3, side plate 7 for installing fastener 5 is arranged around base plate 6, base plate 6 is rectangular, the number of side plates 7 is four and is respectively located on four edges of base plate 6, base plate 6 and side plate 7 form a long rectangular box connecting box with an upper opening, four side plates 7 are formed by sectional cutting of square steel during actual manufacturing (that is, four side plates are integrally formed), so that the structural strength of the whole connecting box is better, a gap is left between side plate 7 and the side wall of pre-buried groove 3, which facilitates the placement of connecting base body 4.

[0027] The fastener 5 adopts a fastening bolt 8, the side plate 7 is provided with a through hole 9 for mounting the fastening bolt 8, the diameter of the through hole 9 is greater than the diameter of the fastening bolt 8, and in the manufacturing process, the diameter of the through hole 9 is 2 times the diameter of the fastening bolt 8. When the anchor 2 and the through hole 9 are skewed (i.e., they are not coaxially distributed), the installation allowance is formed by the diameter difference between the two, which facilitates the installation of the fastening bolt 8 and avoids the error between the two, which leads to the failure of the two walls 1 to be connected and fixed.

[0028] Both sides of the side plate 7 are provided with a spacer plate 10 sleeved on the fastening bolt 8. The spacer plate 10 can protect the side plate 7 from being deformed due to excessive extrusion during fastening. At the same time, the spacer plate 10 can transmit the tension between the fastening bolt 8 and the anchor to the connecting box after connection. The spacer plate 10 is in the shape of a long strip, and its length is greater than the diameter of the through hole 9. A waist hole is formed in the middle of the spacer plate 10 for passing through the fastening bolt 8.

[0029] One end of the anchor 2 is provided with a threaded sleeve 11 for cooperation with the fastening bolt 8, and the other end is provided with a tensile rib 12. The threaded sleeve 11 is used for connection of the fastening bolt 8, and the tensile rib 12 serves to increase the contact area between the end of the anchor 2 and the wall 1, thereby enhancing the connection strength between the anchor 2 and the wall 1.

[0030] The tensile rib 12 is in the shape of a V and the center line coincides with the center line of the fastening bolt 8. The V-shaped rib is selected for one-piece forming, which can improve the strength of the tensile rib body. During installation, a hole is formed at the end of the anchor 2, and then the tensile rib 12 is passed through the anchor and welded and positioned.

[0031] In use, as shown in Figure 4 , the two walls 1 are placed in parallel, the connecting base 4 is placed between the two walls 1, and is preferably placed at the center of the two pre-buried grooves 3. After placement, the optimal state is that the through hole 9 on the side plate 7 is coaxially distributed with the threaded sleeve 11 on the anchor 2. If coaxial distribution cannot be guaranteed, the connecting base 4 can be moved so that the threaded sleeve 11 is located inside the through hole 9, which facilitates the installation of the fastening bolt 8. After fastening is completed, the gap is filled with concrete to seal the joint.

[0032] Example 2

[0033] The same as in example 1 will not be described again, and the difference is that, as shown in Figure 5 , the two walls 1 are placed vertically. At this time, the connecting base 4 is placed in the storage cavity formed by the two pre-buried grooves 3. At this time, the fastening bolt 8 is installed on the two adjacent side plates 7, which can complete the rapid connection of the corner position in the building process.

[0034] Example 3

[0035] The similarities with Example 1 will not be repeated here; the differences are as follows: Figure 6 As shown, this is an installation method using box-type connectors for three wall panels 1, namely the outer main wall, side wall, and top wall panel. Anchors 2 are pre-installed in each of the three wall panels. A storage slot for placing the connector box is opened on the side wall. The connector base 4 is made of square steel cut into a hollow connector box. A through hole 9 is opened on the side wall of the connector box. The diameter of the through hole 9 is larger than the diameter of the fastening bolt 8. The connector box is placed in the storage slot so that the through hole 9 coincides with the threaded sleeve 11. Then, the pad 10 is placed inside the connector box. Finally, the fastening bolts 8 are installed on the three side walls of the connector box. The pad 10 is long and has a waist hole in the middle. The width of the waist hole is smaller than the diameter of the nut on the fastening bolt 8. After the fastening bolt 8 is installed, the nut at the top presses the pad 10 down to a position where it fits against the side wall of the connector box. This transfers the tension of the fastening bolt 8 connected to the threaded sleeve 11 to the connector box. After all three fastening bolts 8 are installed, the splicing of the three wall panels 1 is completed.
