Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a positioning device for reinforcing bars inserted in transition layers. Background Technology
[0002] At the transfer layer, the connection between cast-in-place and precast walls is involved. The effectiveness and quality of the connection largely depend on the accuracy of the positioning of the vertical reinforcing bars pre-installed in the cast-in-place wall. In previous projects, reinforcing bar positioning devices were used to ensure the accuracy of the reinforcing bar positioning.
[0003] Existing rebar positioning devices have fixed dimensions and openings. When encountering precast walls with different dimensions and rebar spacing, the rebar positioning devices need to be re-fabricated. More importantly, existing rebar positioning devices cannot reinforce the rebars, making them prone to displacement. The rebars must be readjusted before the precast wall is hoisted before installation. Utility Model Content

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] Please see Figures 1 to 5 The positioning device for reinforcing bars in the conversion layer of this utility model includes a positioning steel plate 100. The front and rear edges of the positioning steel plate 100 are provided with upwardly bent flanges 110. The front and rear edges of the positioning steel plate 100 are bent upward at ninety degrees to form a U-shaped structure. The top of the positioning steel plate 100 is provided with three sets of concrete injection holes 120. On both sides of the concrete injection holes 120, multiple sets of reinforcing bar holes 180 are opened on the top of the positioning steel plate 100. A sleeve 181 is welded to the top of the positioning steel plate 100 at the edge of each set of reinforcing bar holes 180.
[0031] Multiple positioning components 140 are fixed at equal intervals on the outer wall of the folded edge 110. A locking block 170 for the horizontal insert is fixed on one side of the sleeve 181. An arc groove 171 is reserved on the side of the block 170 near the arc groove 171. Arc plates 172 are rotatably connected to both ends of the block 170. A clearance groove 173 is reserved at one end of the arc plate 172.
[0032] The positioning assembly 140 includes a base 141 fixed to the outer wall of the flange 110. A cap 142 is rotatably mounted between two sets of bases 141 via a damping shaft. The bottom of the cap 142 is used to fit onto the end of a connecting reinforcing bar. The connecting reinforcing bar refers to a reinforcing bar welded to the outer wall of the flange 110 and to the bottom reinforcing bar of the floor slab, used to fix the positioning steel plate 100 during pouring. The positioning assembly 140 also includes a connecting disc 144 fixedly connected to both ends of the damping shaft. A pointer 143 is fixed at the center of the end face of the connecting disc 144.
[0033] The base 141 has a circular channel at the contact position between the damping shaft and the connecting plate 144; the outer wall of the base 141 is fixed with an identification ring 145 that is sleeved on the outside of the connecting plate 144, and the end face of the identification ring 145 has multiple sets of reference strips 146 at equal intervals along its annular circumference.
[0034] The positioning steel plate 100 is horizontally fitted with transverse steel bars 150 at the position of multiple sets of arc grooves 171, and the steel bar holes 180 are fitted with insert bars 160 that are perpendicular to the transverse steel bars 150.
[0035] A positioning steel plate 100 is placed at the connection between the cast-in-place layer and the precast wall. Inserted reinforcing bars 160 extend from the bottom of the positioning steel plate 100 through reinforcing bar holes 180 and sleeves 181 to the top. Simultaneously, transverse reinforcing bars 150 are inserted from both ends of the positioning steel plate 100, positioning the transverse reinforcing bars 150 at the arc grooves 171 of multiple sets of support blocks 170. The design of the arc grooves 171 drives the transverse reinforcing bars 150 towards the inserted reinforcing bars 160, generating a certain pushing force. Figure 1 , Figure 3 and Figure 5 As shown, the aforementioned thrust comes from the weight of the transverse reinforcing bar 150, which will compress the outer wall of the insert bar 160 to fit against the inner wall of the reinforcing bar hole 180 and the sleeve 181, so that the positioning steel plate 100 will not shift. At this time, the arc plate 172 can be rotated around the connection point of the support block 170. The arc plate 172 will fit onto the outer wall of the transverse reinforcing bar 150, and the clearance groove 173 will fit onto the outer wall of the insert bar 160, so that the transverse insert bar is stable and abuts. At this time, the welding work between the insert bar 160, the transverse reinforcing bar 150 and the arc plate 172 can be performed manually.
[0036] like Figure 4 As shown, before welding the dowel bar 160 and the transverse reinforcing bar 150, the cylinder cap 142 can be manually rotated within the base 141 with the damping axis as the center. One end of the connecting reinforcing bar is inserted into the cylinder cap 142 and welded. The other end of the connecting reinforcing bar is welded to the bottom reinforcing bar of the floor slab. When the cylinder cap 142 is rotated, the connecting plate 144 on its end face rotates synchronously. The reference bar 146 corresponding to the pointer 143 can be observed manually to ensure that the rotation angle of multiple sets of cylinder caps 142 is the same. This ensures that the positioning steel plate 100 is in a horizontal position, thereby improving the installation quality of the positioning steel plate 100.
[0037] Please refer to this carefully. Figure 1 , Figure 3 and Figure 5 Two sets of handles 130 are welded to the top of the positioning steel plate 100, and the two sets of handles 130 are distributed at the top of the positioning steel plate 100 near both ends. The worker's hands can grip the outer wall of the handles 130, so as to cooperate to easily move the positioning steel plate 100.
[0038] Please refer to this carefully. Figure 1 There are three sets of concrete injection holes 120, which are equidistantly arranged along the length of the positioning steel plate 100. This allows the poured concrete to fall from the concrete injection holes 120 until it enters the groove at the connection between the cast-in-place layer and the precast wall.
[0039] Please refer to this carefully. Figure 1 The inner wall of the arc plate 172 wraps around the outer wall of the transverse steel bar 150, and the clearance groove 173 is fitted onto the outer side of the dowel bar 160. This stabilizes the transverse steel bar 150 and the dowel bar 160, making welding between them stable and convenient, and improving the strength of the weld.
[0040] In use, the positioning steel plate 100 is placed at the connection between the cast-in-place layer and the precast wall. The dowel bar 160 extends from the bottom of the positioning steel plate 100 through the rebar hole 180 and the sleeve 181 to the top. At the same time, the transverse rebar 150 is inserted from both ends of the positioning steel plate 100, so that the transverse rebar 150 is placed at the position of the arc groove 171 of the multiple sets of support blocks 170. Due to the design of the arc groove 171, the transverse rebar 150 will move closer to the dowel bar 160 and generate a certain pushing force, which will squeeze the outer wall of the dowel bar 160 to fit against the inner wall of the rebar hole 180 and the sleeve 181, so that the positioning steel plate 100 will not be displaced. At this time, the arc plate 172 can be rotated around the connection point of the support block 170. The arc plate 172 will be sleeved on the outer wall of the transverse steel bar 150, and the relief groove 173 will be sleeved on the outer wall of the insert bar 160, so that the transverse insert bar is stable and abuts. At this time, the welding work between the insert bar 160, the transverse steel bar 150 and the arc plate 172 can be carried out manually.
[0041] Before welding the dowel bar 160 and the transverse reinforcing bar 150, the cylinder cap 142 can be manually rotated within the base 141 with the damping axis as the center. One end of the connecting reinforcing bar is inserted into the cylinder cap 142 and welded. The other end of the connecting reinforcing bar is welded to the bottom reinforcing bar of the floor slab. When the cylinder cap 142 is rotated, the connecting plate 144 on its end face rotates synchronously. The reference bar 146 corresponding to the pointer 143 can be observed manually to ensure that the rotation angle of multiple sets of cylinder caps 142 is the same. This ensures that the positioning steel plate 100 is in a horizontal position, thereby improving the installation quality of the positioning steel plate 100.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
