During actual construction, a concrete-filled cavity is usually constructed by using templates such as wood templates, aluminum templates and the like at the stage of beam reinforcement, and pipe fittings are embedded in the cavity, at this time, two ends of each pipe fitting need to be sealed and positioned at preset positions, and then concrete pouring is carried out. The inventor's chinese utility model patent ZL2019205440006 discloses a pipe cover, when in use, an embedded part (i.e. an end cover) is sleeved at two ends of a nested component (i.e. a hollow pipe fitting), the end cover plays a role of sealing two ends of the hollow pipe fitting, the embedded part is placed into a beam/wall cavity after a template is constructed, a fastener such as a screw is fixed on the template through a fixing hole on a fixing part, the nested component is positioned, then concrete can be poured, the template is dismounted after the concrete is poured, the fixing part is usually torn off and separated from the embedded part by the screw when the template is dismounted, and when a pipeline is needed, only the end cover needs to be knocked off; but at this point the form leaves screws and fasteners that need to be cleaned. If standardized construction is carried out, the used template can be repeatedly used on each floor, and the hollow pipe fittings of each floor generally need to be installed at the same positions, so that the screw installation points left on the template can be repeatedly used, and the installation points do not need to be measured and searched again. The problem that the two ends of the pipe fitting are sealed and positioned can be well solved.

However, in the actual construction process, the width of the beam/wall cavity is narrow, usually only 10-40 cm, and if the installation depth of the hollow pipe fitting is deep, a lengthened screwdriver or a flexible shaft needs to be used to go deep into the cavity for screw locking, so that the fixation is very inconvenient. And after the template is dismantled, still need clear up screw and the mounting on the template, then use the screw to fix new end cover on the template again, and all need carry out such operation on every layer, very consuming time and wasting force, the repetitive work volume is big, greatly reduced the efficiency of construction.
