Description

Technical Field

[0001] The utility model relates to the field of building construction, and particularly relates to a reusable positioning device for inserted steel bars of precast wall bodies. Background Technique

[0002] The positioning device for inserted steel bars of precast wall bodies plays a crucial role in building construction. The core function of this device is to accurately position and fix the inserted steel bars in the precast wall bodies. Through preset holes, card slots or other fixing mechanisms, it ensures that the inserted steel bars can be accurately placed according to the design requirements, avoiding deviation or dislocation, so as to ensure the safety and stability of the structure.

[0003] In the use process of some reusable positioning devices for inserted steel bars of precast wall bodies in the prior art, there are usually defects in the poor fixing effect on the square pipes. If the square pipes are not firmly fixed, they may move or shift during the construction process, thus affecting the positioning accuracy of the inserted steel bars. It may also require construction workers to repeatedly adjust the positions of the square pipes and the inserted steel bars, increasing the construction difficulty and time cost. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a reusable positioning device for inserted steel bars of precast wall bodies in view of the current situation of the prior art.

[0005] The utility model is realized through the following technical solutions: The utility model provides a reusable positioning device for inserted steel bars of precast wall bodies, including a bearing mechanism, which includes horizontal square pipes. The number of the horizontal square pipes is two, and two identical vertical square pipes are respectively fixedly connected to one side surface of the two horizontal square pipes;

[0006] A positioning mechanism, a positioning sleeve sleeved on one side surface of the vertical square pipe, and an ear plate is fixedly connected to one side surface of the positioning sleeve.

[0007] By adopting the above technical solutions, the horizontal square pipes can limit the movement of the inserted steel bars in the horizontal direction to ensure that they can remain in the predetermined horizontal position. The vertical square pipes can provide support and positioning for the inserted steel bars in the vertical direction to ensure that they can be vertically installed in the precast wall bodies according to the design requirements. Place the positioning sleeve on the surface of the vertical square pipe, and fix the ear plate to the wall surface through bolts, so that the ear plate, through cooperation with the positioning sleeve, initially fixes the vertical square pipe.

[0008] Furthermore, a support pipe is fixedly installed on the other side surface of the positioning sleeve, and an internally threaded sleeve is slidably connected to the inner surface of the support pipe.

[0009] By adopting the above technical solution, when the internal thread sleeve slides inside the support pipe to a position where it contacts one side surface of the positioning sleeve, it can squeeze both sides of the positioning sleeve through cooperation with the lug, so that the positioning sleeve clamps and fixes the vertical square pipe through friction.

[0010] Further, a lead screw is threadedly connected to the inner surface of the internal thread sleeve. One end of the lead screw is fixedly installed on one side surface of the positioning sleeve through a bearing, and a limiting groove is formed on the inner surface of the support pipe.

[0011] By adopting the above technical solution, the internal thread sleeve is used to support the lead screw to prevent the position of the lead screw from shifting.

[0012] Further, a limiting block is fixedly connected to the outer surface of the internal thread sleeve, and the limiting block is slidably connected inside the limiting groove.

[0013] By adopting the above technical solution, when the lead screw rotates, the internal thread sleeve is limited through the cooperation of the limiting block and the limiting groove, so that the internal thread sleeve performs a linear motion inside the support pipe through the rotation of the lead screw.

[0014] Further, a knob is fixedly connected to the other side of the internal thread sleeve, and a support sleeve is fixedly installed on one side surface of the positioning sleeve.

[0015] By adopting the above technical solution, construction workers can drive the lead screw to rotate synchronously by rotating the knob, and a plurality of slots are formed on the surface of the knob.

[0016] Further, a plug pin is slidably connected to the inner surface of the support sleeve, and a fixing block is fixedly connected to one side surface of the positioning sleeve.

[0017] By adopting the above technical solution, the support sleeve can limit the plug pin. Normally, the plug pin is inserted into the slots formed on the surface of the knob. Through the limitation of the plug pin by the support sleeve, it can be avoided that the knob rotates reversely due to external force or accidental touch, resulting in poor fixing effect of the positioning sleeve on the vertical square pipe.

[0018] Further, one end of the plug pin is fixedly connected with a connecting rod and a spring. The connecting rod is slidably connected to the inner surface of the fixing block, and the other end of the spring is fixedly connected to one side surface of the fixing block.

[0019] By adopting the above technical solution, pulling the connecting rod can drive the plug pin to move outside the slot, thereby releasing the limitation on the knob. Through the cooperation of the plug pin and the fixing block, a pressure can be applied to the spring.

[0020] Further, the positioning mechanism further includes a positioning block, and the positioning block is fixedly connected to the other end of the connecting rod.

[0021] By adopting the above technical solution, when the connecting rod is loosened, the spring can reset the bolt through its own reaction force. Through the cooperation of the positioning block and the fixed block, the bolt can be prevented from popping out of the support sleeve.

[0022] The utility model has the following beneficial effects compared with the prior art:

[0023] Through the mutual cooperation of the components in the positioning mechanism of the utility model, the reverse rotation of the knob caused by external force or accidental touch can be avoided, so that the positioning sleeve releases the clamping and fixing of the vertical square pipe, thereby achieving the effect of reducing the construction difficulty and time cost.

Both the horizontal square pipe 101 and the vertical square pipe 102 are made of galvanized material, and the ear piece 202 can install the positioning sleeve 201 on the wall surface through cooperation with bolts.

[0033] As shown in Figure 2 and Figure 4 As shown, a support pipe 203 is fixedly installed on the other side surface of the positioning sleeve 201. An internally threaded sleeve 204 is slidably connected to the inner surface of the support pipe 203. The positioning sleeve 201 is used to support the support pipe 203, and the support pipe 203 is used to support the internally threaded sleeve 204.

[0034] As shown in Figure 4 As shown, a lead screw 205 is threadedly connected to the inner surface of the internally threaded sleeve 204. One end of the lead screw 205 is fixedly installed on one side surface of the positioning sleeve 201 through a bearing. A limiting groove 206 is opened on the inner surface of the support pipe 203. A limiting block 207 is fixedly connected to the outer surface of the internally threaded sleeve 204, and the limiting block 207 is slidably connected in the limiting groove 206. The internally threaded sleeve 204 is used to limit the lead screw 205, and the limiting groove 206 is used to limit the internally threaded sleeve 204 through the limiting block 207.

[0035] As shown in Figures 2 - 4 As shown, a knob 208 is fixedly connected to the other side of the internally threaded sleeve 204. A support sleeve 209 is fixedly installed on one side surface of the positioning sleeve 201. Rotating the knob 208 can drive the lead screw 205 to rotate synchronously. Through the limiting groove 206 for limiting the internally threaded sleeve 204 through the limiting block 207, the internally threaded sleeve 204 can perform linear motion through the rotation of the lead screw 205.

[0036] As shown in Figure 3As shown, a latch 210 is slidably connected to the inner surface of the support sleeve 209, and a fixing block 211 is fixedly connected to one side surface of the positioning sleeve 201; one end of the latch 210 is fixedly connected to a connecting rod 212 and a spring 213, the connecting rod 212 is slidably connected to the inner surface of the fixing block 211, and the other end of the spring 213 is fixedly connected to one side surface of the fixing block 211; the positioning mechanism 200 further includes a positioning block 214, and the positioning block 214 is fixedly connected to the other end of the connecting rod 212; the support sleeve 209 is used to limit the latch 210, the fixing block 211 is used to support the connecting rod 212, the spring 213 is used to reset the latch 210, and through the cooperation of the positioning block 214 and the fixing block 211, it is possible to prevent the latch 210 from popping out of the support sleeve 209.

[0037] The specific implementation process of this embodiment is as follows: Pull the connecting rod 212 to drive the latch 210 to move outside the slot, so as to release the limit on the knob 208. Rotate the knob 208 to drive the lead screw 205 to rotate synchronously. Limit the inner threaded sleeve 204 through the limit block 207, so that the inner threaded sleeve 204 can perform a linear motion through the rotation of the lead screw 205.

Release the connecting rod 212, and the spring 213 will reset the latch 210 through the reaction force, so that the latch 210 is inserted into the slot. Through the cooperation of the positioning block 214 and the fixing block 211, it is possible to prevent the latch 210 from popping out of the support sleeve 209. Through the limit of the latch 210 by the support sleeve 209, the latch 210 limits the knob 208, so as to avoid the knob 208 from rotating in the reverse direction due to external force or accidental touch, resulting in the positioning sleeve 201 releasing the clamping and fixing effect on the vertical square tube 102.
