Description
Technical Field
The utility model relates to the technical field of prefabricated stair support embedded part bolt fixing, in particular to an assembled structure prefabricated stair support embedded part bolt fixing device.
Background
The assembled building has the characteristics of green, energy saving, low carbon and environmental protection, is easy to realize building component, building industrialization and industrialization, and is widely applied in China in recent years. In the construction of an assembled structure, the construction of the prefabricated staircase is an indispensable ring for connecting an upper layer and a lower layer. In order to prevent the pre-buried bolts of the stair support from being deviated and affecting later installation, the pre-buried bolts are required to be fixed. The traditional fixing mode is to place the embedded bolt by punching holes in the template, but due to the deviation of the embedded bolt caused by various factors, the time and the labor are consumed in the process of installing the prefabricated staircase in the later period.
Disclosure of Invention
The utility model aims to make up the defects of the prior art and provides a bolt fixing device for an embedded part of a prefabricated stair support with an assembled structure.
The utility model is realized by the following technical scheme:
the utility model provides an assembled structure prefabricated staircase support built-in fitting bolt fixing device, including setting device and pre-buried bolt, setting device is including rectangular frame, is equipped with extension board and last extension board respectively on rectangular frame's left side lower part and right side upper portion, will setting device places in prefabricated staircase's template department, and wherein lower extension board and last extension board are fixed in prefabricated staircase's template department through penetrating the nail respectively, open respectively on rectangular frame's up end and lower terminal surface and have upper and lower bolt hole that corresponds from top to bottom, are fixed with spacing sleeve pipe in rectangular frame's lower terminal surface position department of lower screw hole, advance bolt hole, spacing sleeve pipe and lower bolt hole in proper order with pre-buried bolt to insert prefabricated staircase inside.
The top end of the limit sleeve is in clearance fit with the embedded bolt.
And the limit sleeves are respectively welded on the lower end face of the rectangular frame.
The connecting position of the embedded bolt and the upper end face of the shaping device is reinforced by a reinforcing nut.
The utility model has the advantages that: the utility model can improve the positioning precision of the bolts, ensure the positioning accuracy, improve the working efficiency of hoisting stairs and reduce the engineering cost; the operator only needs to install the device at the stair formwork, and the device can be circularly applied after the device is dismantled after the concrete pouring is completed, so that the disassembly and assembly operation are convenient.
