Embodiment 1

[0031] Such as Figure 1 to Figure 4 As shown in the figure, the casing inserting bar positioning device is reserved for the transfer layer of the prefabricated building, including a fixed frame 1 and a positioning mechanism. Eight floor thickness control parts 2 are welded and fixed on the fixed frame 1, and the top of the floor thickness control part 2 is provided with a connection Part 6, the top surface of the poured concrete is flush with the top surface of the connecting part 6. The connecting part 6 is a conical structure with a large upper part and a smaller lower part, which is convenient for dismantling and reusable to save cost when demoulding later, and the upper and lower ends are respectively provided with Threaded hole, the connecting piece 6 is screwed to the top of the floor thickness control piece 2.

[0032] The positioning mechanism is located on the top of the fixed frame 1. The positioning mechanism includes a construction platform 3 and a clamping unit 4...

Embodiment 2

[0036] Such as Figure 5 Shown, the construction method of this device comprises the following steps:

[0037] Step 1. Fix the fixed frame 1 and the main steel structure, and level it to the levelness required by the design, so as to provide a levelness reference basis for the construction platform 3;

[0038] Step 2. Thread the bottom of the adjustment part 5 to the top of the connection part 6, and pass the top of the adjustment part 5 through the construction platform 3, and adjust the construction platform 3 to a horizontal state by adjusting two nuts, so as to ensure that the pipe sleeve is reserved The angle of insertion of the ribs;

[0039] Step 3: Install the two positioning rods 9 with the positioning block 16 in the waist hole 13 of the buckle 11 of the adjustment part 5, and ensure that one is fixed and the other can move horizontally, and buckle with the buckle 11 of the adjusting gasket 8 Close on the construction platform 3, and then pass through the two connect...

Abstract

The invention discloses a positioning device and a construction method for reserved sleeve steel dowels of a transfer layer of a prefabricated building, and belongs to the technical field of buildingconstruction. The positioning device comprises a fixed frame and a positioning mechanism, wherein a floor slab thickness control part is fixedly connected on the fixed frame; the positioning mechanismis positioned at the top of the fixed frame and comprises a construction platform and a clamping unit; a regulating part is arranged on the construction platform, and the construction platform is matched and connected with the floor slab thickness control part through the regulating part; and the clamping unit is adjustably connected on the construction platform and is used for clamping the reserved sleeve steel dowels. The positioning device has a simple structure, is convenient to operate, can be used repeatedly so as to save the construction cost, can be widely applied to the positioning and fixation of the reserved sleeve steel dowels of the transfer layer, and effectively solves the problems that the sleeve steel dowels is inaccurate in positioning and difficult in fixation and deform and move during concrete pouring, so that an upper prefabricated structure cannot be mounted.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a positioning device and a construction method for casing inserting ribs reserved for a transfer layer of a prefabricated building. Background technique [0002] In order to meet the overall structural requirements of the prefabricated building, the vertical reinforcement connection of the wall panels is connected by sleeve grouting. During the construction of the standard layer, the reserved ribs of the prefabricated components of the lower layer are inserted into the sleeves of the upper layer, and the grouting connection is dense. During the construction of the transfer floor, the lower ribs need to be inserted into the cast-in-place beams and slabs, which makes positioning and fixing difficult. When pouring concrete, it is easy to cause deformation and deviation of the inserted ribs, so that the position of the sleeve of the upper prefabricated comp...
