Description
Technical Field
The invention relates to the field of building construction, in particular to a construction method for civil construction and air pipe synchronization of an air shaft lining air pipe.
Background
The ventilation air pipe is a metal or composite lining air pipe for ventilation and air conditioning engineering of industrial and civil buildings, is a municipal infrastructure for making air circulation and reducing harmful gas concentration, and can effectively ensure the quality of air when the lining air pipe is ventilated in a civil air shaft.
The construction method of the prior conventional vertical air shaft lining air pipe is divided into three types: the construction can be finished in advance, and then the air duct is installed, because the space is narrow after the construction of the vertical air shaft is finished, no working space exists during the installation of the air duct, and even if the vertical air shaft is hoisted downwards from the upper part, no space exists at the joint of different air duct sections for manual connection and reinforcement, the quality cannot be ensured, and air leakage is easy to occur; secondly, the air pipes are installed firstly and then follow-up civil construction and building construction is carried out, so that the air pipes can be effectively connected and fixed, but the constructional columns at the corners of the civil construction in the building process of the air shaft have no operation space for supporting and reinforcing the templates, and certain extrusion deformation can be caused to the air pipes by forced reinforcement. In addition, concrete leaks out during the process of building the constructional column by civil engineering and seriously pollutes the air pipe; the civil engineering builds a structure partial wall body, then treats that the tuber pipe installation accomplishes the connection after, continues to build remaining wall body by laying bricks or stones again, and nevertheless the civil engineering is discontinuous like this, and the brickwork constructional column of back construction can not form abutment joint form, and the part is built by laying bricks or stones after, and the overall stability is relatively poor for the building structure partial, and civil engineering and tuber pipe installation often are different class and group's kind in addition, and the in-process is coordinated the degree of difficulty big, and the construction is asynchronous, no matter who is under construction alone respective content all can cause great influence to another kind of work.

As optimization, the linking tuber pipe includes that two section at least concatenation tuber pipes end to end connect forms, and the concatenation tuber pipe includes the body, and the mouth of pipe outside fixedly connected with at both ends encircles the fixed curb plate of establishing along mouth of pipe edge extending direction about the body, the central line direction perpendicular to fixed curb plate place plane of body, two fixed curb plate butts on the link of two adjacent sections concatenation tuber pipes are in the same place and carry out fixed connection through connecting bolt. The mode of splicing multiple sections of air pipes is adopted, so that the influence caused by insufficient strength of the air pipe body is avoided.
As optimization, two on the link of concatenation tuber pipe the outside of fixed curb plate is provided with the rubber card strip, is provided with the draw-in groove that extends the setting along rubber card strip extending direction on the rubber card strip, and the draw-in groove is logical groove, and the rubber card strip passes through the draw-in groove chucking and in two on the link of concatenation tuber pipe on the outside side of fixed curb plate, two the outside edge butt of fixed curb plate is on the tank bottom of draw-in groove. The sealing performance is improved.
In conclusion, the beneficial effects of the invention are as follows: according to the invention, the rear plug opening is arranged on the air shaft wall body during civil construction, and the lining air pipe is installed during the reserved period of the rear plug opening, so that the civil construction and the installation cannot interfere with each other, and the installation personnel can conveniently install and fix the lining air pipe outside and inside the air shaft wall body through the rear plug opening, thereby reducing the construction difficulty.
