Description

Technical Field

[0001] The utility model relates to the technical field of building assembled structures, in particular to an adjustable assembled transfer layer reserved dowel positioning device. Background Art

[0002] Currently, in most prefabricated concrete shear wall structures, the lower foundation and bottom reinforcement layer are cast-in-place, while the upper structure is prefabricated. The transition zone between cast-in-place construction and prefabricated hoisting installation is the transition layer. This transition layer is connected to the prefabricated shear wall reinforcement sleeves using inserted rebar.

[0003] However, the existing steel bar grinding, positioning and correction processes take too long compared to the standard assembly layer. This phenomenon is caused by the serious deviation and bending of the reserved steel bars in the cast-in-place layer. Almost every bar needs to be positioned according to the requirements. Based on this, the utility model designs an adjustable pre-reserved reinforcing bar positioning device for the assembled transfer layer to solve the above problem. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please refer to Figure 1-Figure 3 , an adjustable assembled transfer layer reserved dowel positioning device, comprising:

[0026] The transverse positioning structure includes a transverse positioning steel plate 1, which is a U-shaped hollow structure and is used for inserting reinforcement positioning;

[0027] Vertical positioning structures, which are located on both sides of the horizontal positioning structure and are used to position the horizontal positioning structure;

[0028] The vertical sleeve structure is installed in the inner cavity of the transverse positioning structure and is used for positioning. The vertical sleeve mechanism includes a sleeve assembly and a gasket assembly. The sleeve assembly is located at the top of the transverse positioning structure and is used for inserting reinforcement positioning. The gasket assembly is located at the bottom of the sleeve assembly and is used to fix the sleeve assembly.

[0029] The horizontal positioning steel plate 1 includes a horizontal hollow plate 7 and a vertical fixing plate 8 installed on the top of the horizontal hollow plate 7. The horizontal hollow plate 7 and the vertical fixing plate 8 are an integrated structure bent from the same steel plate. The vertical positioning structure includes a hollow steel plate 9 installed on the top of the horizontal hollow plate 7. A bolt 10 is installed on one side of the hollow steel plate 9. The bolt 10 passes through the hollow groove of the hollow steel plate 9 and extends to the vertical fixing plate 8. A nut 11 is installed on the outer ring of the bolt 10.

[0030] In the embodiment of the present invention, when in use, the transverse positioning steel plate 1 is first connected to the vertical positioning structure by bolts 10, but the bolts 10 are not tightened, so that the transverse positioning steel plate 1 can move freely along the vertical positioning structure. When the transverse positioning steel plate 1 is coaxial with the reserved dowel design position, the bolts 10 are tightened to fix the transverse positioning steel plate 1.

[0031] Please refer to Figure 1-Figure 4 The sleeve assembly includes a lower sleeve 5 and an upper sleeve 4 installed on the top of the lower sleeve 5. The inner side of the upper sleeve 4 is provided with a thread, and the outer side of the lower sleeve 5 is provided with a thread matching the inner thread of the upper sleeve 4. The lower sleeve 5 passes through the hollow hole of the horizontal positioning steel plate 1 and the bottom of the lower sleeve 5 is fixedly connected to the gasket assembly.

[0032] The gasket assembly includes a gasket body 6 and the gasket body 6 is installed at the bottom of the lower sleeve 5. There are two groups of sleeve assemblies and gasket assemblies and they are distributed horizontally. The horizontal positioning structure, the vertical positioning structure and the vertical sleeve structure are all fixedly connected by a bolt 10 structure. The vertical sleeve structure can be adjusted in the longitudinal and transverse directions.

[0033] In the embodiment of the present utility model, the lower sleeve 5 of the vertical sleeve structure is a hollow bolt, and the size of the expanded end portion is larger than the width of the hollow groove of the horizontal positioning steel plate 1. After the lower sleeve 5 is passed through the horizontal positioning steel plate 1, the gasket body 6 is put on to increase the contact area between the vertical sleeve structure and the horizontal positioning steel plate 1. The inner side of the upper sleeve 4 is provided with a thread matching the outer side of the lower sleeve 5. After aligning the upper sleeve 4 with the lower sleeve 5, the lower sleeve 5 is screwed in and not tightened temporarily. At this time, the vertical sleeve structure can move freely in the hollow groove of the horizontal positioning steel plate 1. When the vertical sleeve structure moves to the reserved dowel design position, the upper sleeve 4 and the lower sleeve 5 are tightened.

[0034] During use, the combined structure is fixed at the transition layer between the cast-in-place and prefabricated structures. Before pouring the cast-in-place structural concrete, the vertical positioning structure is fixed to the structural reinforcement or formwork. The vertical fixing plate 8 of the transverse positioning steel plate 1 is connected to the vertical positioning structure via bolts 10. The lower sleeve 5 in the vertical sleeve structure passes through the horizontal hollow plate 7 of the transverse positioning steel plate 1, and then the gasket body 6 is placed in and aligned with the upper sleeve 4 and screwed in. The hollow groove of the vertical positioning structure ensures that the transverse positioning steel plate 1 and the vertical sleeve structure can move freely in the longitudinal direction. Not only can the reserved dowels be accurately positioned according to the designed position, but they can also be disassembled and used for turnover, greatly improving construction efficiency.

[0035] After the vertical sleeve structure is fixed at the reserved dowel design position, the dowel is passed through the vertical sleeve structure and welded to other structural steel bars. After the cast-in-place structural concrete is poured and reaches a certain strength, the upper sleeve 4 and the lower sleeve 5 of the vertical sleeve are loosened, the upper sleeve 4 and the gasket body 6 are removed, and then the bolts 10 connecting the transverse positioning steel plate 1 and the vertical positioning structure are loosened, the transverse positioning steel plate 1 is removed, and then the lower sleeve 5 is removed, and finally the vertical positioning structure is removed. After the entire device is dismantled, it is moved to the next location for standby use.

[0036] The device has a simple structure and realizes the longitudinal and transverse linear continuous adjustment of the positioning sleeve position. It can be applied to any different design reserved dowel sizes and has precise positioning, avoiding a series of extra work caused by the inaccurate positioning of reserved dowels in traditional methods. At the same time, it can be disassembled and turned around, greatly improving construction efficiency.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
