Description

Technical Field

[0001] The utility model relates to the field of spray branch pipes, in particular to a node for assembling and installing spray branch pipes. Background Art

[0002] In the construction of mechanical and electrical installation, the spray branch pipes are usually installed section by section on site after cutting according to the design drawings. However, such a method has some problems: (1) The design drawings meet the specification requirements but do not optimize the dimensions in modulus. After the pipes are segmented, there are many length specifications, resulting in large material losses. (2) Workers install the spray branch pipes section by section at high altitude by lifting the lifting vehicle, which requires frequent movement of the lifting vehicle, with low work efficiency; the high-altitude operation time is long and the safety is low. The installation operation must be carried out after the work surface is handed over on site and cannot be carried out in advance in an interspersed manner, affecting the construction progress.

[0003] Therefore, it is necessary to design a node for assembling and installing spray branch pipes. Content of the Utility Model

[0005] A node for assembling and installing spray branch pipes includes a spray main pipe and a plurality of spray branch pipe modules. The spray main pipe is threadedly connected to the plurality of spray branch pipe modules through a plurality of main pipe tees and a plurality of connecting short pipes. The threading directions of the two ends of the connecting short pipe are opposite, and the threading direction of the spray branch pipe module is opposite to that of the corresponding main pipe tee. When the connecting short pipe is connected to the spray main pipe and the spray branch pipe module, it is connected through a temporary fixing bracket.

[0006] Further, a sleeve is provided at the connection between the connecting short pipe and the spray branch pipe module.

[0007] Further, a leveling instrument is provided on the temporary fixing bracket.

[0008] Further, the temporary fixing bracket includes a first clamp and a second clamp. The first clamp clamps the spray main pipe, and one end of the second clamp is connected to the first clamp and the other end clamps the spray branch pipe module.

[0009] Further, a chute is provided at one end of the first clamp away from the spray main pipe, and the second clamp is movably connected in the chute.

[0010] Further, a slider is provided at one end of the second clamp close to the first clamp, and the slider is sleeved in the chute.

[0011] Further, a plurality of spray heads are provided on the spray branch pipe module.

[0012] Furthermore, the spray nozzles on several of the spray branch pipe modules are arranged in rows and columns.

[0013] Compared with the prior art, a node for assembling and installing a spray branch pipe provided by the present utility model has the following beneficial effects:

[0014] In the node for assembling and installing a spray branch pipe of the present utility model, the overall branch pipe is assembled on the ground instead of in the air, shortening the aerial operation time, greatly improving the operation efficiency and construction quality. The threading directions at both ends of the connecting short pipe connecting the main pipe tee and the branch pipe are opposite; the threading direction of the corresponding branch pipe is opposite to the original threading direction. This method can enable the short pipe to be screwed into the main pipe tee and the branch pipe simultaneously at both ends when the short pipe rotates in one direction.
