Technical Field

The invention relates to the field of fire fighting construction, in particular to a pre-buried structure of a fire fighting water system branch pipe.

Background

At present, because domestic fire fighting is not assembled, unified design, standard construction and management are not realized, the pipeline arrangement is different, the construction problem is more, the collision is more, and the installation belongs to the low efficiency of high altitude construction, potential safety hazard. With regard to technical process analysis, adopt the pre-buried pipeline of assembled, it is efficient, the unified standard of installation quality reduces pre-buried mistake worker and waves worker, but has two factors that restrict fire pipeline pre-buried at present: 1. the design is not standardized, and the distances among all spraying points are different, so that prefabrication is difficult. 2. If the pre-buried water pipe is broken and leaked, the maintenance is difficult. The first problem can be solved by the published patent (application No. 202010023786.4), and the technology is used for standardizing the distance between the spraying nodes and determining the positions of the spraying nodes, so that the fire hose embedding possibility is realized.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the problem of the pre-buried pipe fitting of assembled can't be realized to present fire pipeline construction provides a new pre-buried structure.

The technical scheme of the invention is as follows:

the utility model provides a pre-buried structure of fire water system branch pipe assembled, includes the prefabricated plate, pre-buried sleeve pipe and terminal box in the prefabricated plate, and the terminal box is located the prefabricated plate both ends, sleeve pipe and terminal box intercommunication, and fire water system branch pipe is installed in the sleeve pipe, with two fire water system branch pipes of tee junction and installation shower head in the terminal box.

When a spray head cannot be installed at a preset position at a position where a ceiling is decorated, the spray head can be connected with a tee joint through a hose to bypass the position of the ceiling, or the spray head is connected with a junction box tee joint to perform downward spraying, and a heat collecting plate is additionally arranged.

The branch pipe of the fire water system is a PVC-C pipe.

The prefabricated plate and the fire water system branch pipe are both standard lengths.

Two terminal boxes are spliced into a wiring space after the two prefabricated plates are spliced, and the space size meets the requirement that the fire water system branch pipe can be inserted into the sleeve pipe under the condition of no plastic deformation.

The junction box is a six-sided box lacking an upper surface and one side.

The junction box can also be a six-sided box body with the upper surface, the lower surface and one side surface missing, and the sleeve is pre-embedded on the central axis of the prefabricated slab in the length direction.

An assembly type pre-embedding method for branch pipes of a fire water system is characterized by comprising the following steps:

optimizing a design drawing, and adjusting the position of each spraying node on a pipeline to enable the distance between two adjacent nodes to be a standard distance;

b prefabricating a prefabricated panel according to claim 5;

c, assembling the precast slabs;

d, inserting the branch pipe of the fire fighting water system and installing a tee.

The prefabricated slab adopts cast-in-place, steel bars are embedded in the prefabricated slab, and a sleeve and a junction box are arranged according to intervals and adopt an integrated seamless structure

The invention has the beneficial effects that:

adopt double-deck pre-buried mode, pre-buried sleeve pipe then inserts fire water system branch pipe earlier, even damage appears in the pipeline like this, also can take out the pipeline and change the new water pipe, solved the difficult problem of pre-buried water pipe maintenance.

The assembly type pre-buried pipeline is adopted, the efficiency is high, the installation quality is unified and standard, pre-buried malfunction wave work and collision are reduced, the post-assembly type standardized construction is efficient and rapid, the construction period is short, and the development prospect is wide.

At present, the invention advocates a building assembly type in China, and the invention meets the requirement of pre-embedding fire-fighting water pipelines when the concrete wall top ground factory is prefabricated, thereby improving the assembly utilization rate. For the position that has the fitment furred ceiling, can be totally according to 3 meters unified spacing branch pipes pre-buried, can neglect the accuracy, spout down and adopt the hose adjustment in 1.8 meters to compensate distance error. The pre-embedding process can be applied to prefabrication of an assembly type building factory and can also be applied to a process of pre-embedding and pouring concrete on site.
