Different types of pipes have different precision requirements for pipe docking, and there will be installation errors during construction. It cannot be fully guaranteed that the construction meets the precision requirements for pipe docking, which increases the construction period and cost. The invention patent with announcement number CN111335558B discloses a device for fixing drainage pipes on the exterior wall of a building, including a connector for connecting two adjacent drainage pipes, and a fixing structure for fixing the drainage pipe or the connector; the connector includes an outer sleeve, and an inner sleeve is connected to the outer sleeve through a connecting ring; a plurality of drainage grooves are provided on the upper surface of the connecting ring, and drainage holes connected to the drainage grooves are provided on the inner sleeve; the fixing structure includes a fixing seat fixed on the wall, and two arc-shaped clamps are detachably installed on the fixing seat, and a locking screw assembly is also connected between the two arc-shaped clamps, so that two drainage pipes installed on the exterior wall and located in the upper and lower positions can be connected, and the stability after installation is high, but the device cannot adapt to large installation errors and has poor adjustability.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An adjustable connection device for docking water supply and drainage pipes in assembled buildings, comprising a basic connection plate fixedly mounted on a main structure and a cantilever bracket cantilevered on one side of the basic connection plate, wherein a plurality of first waist-shaped holes are arranged on the basic connection plate; a plurality of second waist-shaped holes are arranged on the side wall of the cantilever bracket, and a connecting piece can be detachably mounted on the second waist-shaped holes, and the drainage pipe is fixedly connected to the cantilever bracket via the connecting piece.

[0006] Preferably, the base connecting plate and the cantilever bracket are made of steel plates by bending them into one piece.

[0007] Preferably, the cantilever bracket is U-shaped as a whole, and a plurality of the second waist-shaped holes are symmetrically arranged on two side walls of the cantilever bracket.

[0008] Preferably, a diagonal brace bracket is detachably provided between the bottom of the cantilever bracket and the main structure.

[0009] Preferably, the connecting member is a U-bolt.

[0010] Preferably, an arc-shaped support member is detachably mounted on the cantilever bracket, and the drainage pipe is arranged between the arc-shaped support member and the connecting member.

[0011] Preferably, a reinforcing connector is detachably installed between the base connecting plate and the cantilever bracket.

[0012] In the utility model, the device can achieve horizontal and vertical installation error adjustment through the first waist-shaped hole and the second waist-shaped hole, and can also adapt to the fixed connection of pipes in different installation positions, with good installation fault tolerance, ensuring the accuracy requirements when the pipes are connected, and improving the convenience of installation. The basic connecting plate and the cantilever bracket are made of steel plates by bending into one piece, with low manufacturing cost. The reinforced connector and the diagonal support bracket improve the installation stability of the device, and the arc-shaped support increases the contact area when the drainage pipe is fixed, avoiding the disadvantage that the drainage pipe is affected by shaking during subsequent use.

[0016] The utility model is further described below in conjunction with the accompanying drawings:

[0017] like Figure 1 and Figure 2An adjustable connection device for docking water supply and drainage pipes of an assembled building is shown, comprising a base connection plate 2 fixedly mounted on a main structure 1 by fasteners and a cantilever bracket 3 cantilevered on one side of the base connection plate 2. Of course, the main structure 1 can also be a weighing wall panel. The base connection plate 2 and the cantilever bracket 3 are made of 4 mm thick galvanized steel plates by bending into one piece. In a preferred embodiment, a plurality of connection holes are provided at the bottom of the cantilever bracket 3, and a diagonal brace bracket 4 is detachably provided between the bottom of the cantilever bracket 3 and the main structure 1 by fasteners, one end of the diagonal brace bracket 4 is connected to the connection hole by bolts, and the other end of the diagonal brace bracket 4 is connected to the main structure 1 by bolts.

[0018] A plurality of first waist-shaped holes 5 are provided on the base connecting plate 2. During installation, bolts are used to pass through the first waist-shaped holes 5 to install the device on the main structure 1. The lateral installation position of the device can be adjusted through the first waist-shaped holes 5. In this embodiment, the installation position can be specifically adjusted by 3 cm.
