Description

Technical Field

[0001] This utility model relates to the field of pre-embedded conduit technology in building construction, and in particular to a PVC conduit pre-embedded positioning device. Background Technology

[0002] In the initial stage of water and electricity pre-installation during building construction, accurate positioning is crucial. Before the reinforcement is laid, the conduits need to be positioned on the roof slab according to the drawings. The accuracy of the conduit positioning directly affects the smooth progress of subsequent construction. If the conduit position does not match the electrical drawings, it may lead to difficulties in later installation or misalignment of reserved holes, affecting structural stability.

[0003] Traditional pre-embedded hole method requires repeated adjustment of hole position on template. If the positioning is not accurate, it is necessary to repeat the drilling or repair of template, which increases the construction cost and installation time of workers. If the PVC conduit is misaligned, it can easily lead to problems such as conduit breakage and grout leakage.

[0004] To ensure that the conduit is not displaced or damaged during concrete pouring, it is necessary to securely tie the conduit to the reinforcing steel with wire at intervals. At the same time, where there are joints in the conduit, it is necessary to tie the wire to both sides of the joint. Traditional tying and fixing methods are inefficient and make it difficult to guarantee the accuracy of the conduit's position. Utility Model Content

[0005] In view of this, the present invention aims to provide a PVC conduit pre-embedded positioning device, which can improve the positioning accuracy and firmness of PVC conduits while improving construction efficiency.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A PVC conduit pre-embedded positioning device includes a fixing plate, at least two plug-in assemblies slidably connected to the fixing plate, locking assemblies disposed on both sides of the fixing plate, a number of support members spaced apart along the length direction of the fixing plate, and a number of positioning assemblies for limiting the displacement of the laid conduit.

[0008] The plug-in assembly is plugged into the joint of the reinforcing bars. The plug-in assembly is provided with a plurality of elastic cards. The inner circumference of the elastic cards forms an insertion space. When the fixing plate is pushed close to the reinforcing bars, the elastic cards deform to expand the insertion space. When the joint of the reinforcing bars is located in the insertion space, the elastic cards rebound and abut against the reinforcing bars.

[0009] The locking assembly is driven to abut against the same adjacent reinforcing bar, thereby restricting the displacement of the fixing plate;

[0010] The support member has a cavity formed inside for holding the upturned tube.

[0011] Furthermore, the plug-in assembly includes a circular plate, a sliding post connected to the circular plate, and a baffle plate disposed on the sliding post;

[0012] The fixed plate is provided with a long groove arranged along its length, the sliding column is disposed in the long groove, and the baffle is disposed above the fixed plate;

[0013] The four elastic cards are evenly distributed around one end of the circular plate, and the spacing between two adjacent elastic cards is adapted to the diameter of the reinforcing bar.

[0014] Furthermore, the elastic card has a hook that bends toward the insertion space on the side away from the circular plate;

[0015] The hook has a first inclined surface and a second inclined surface. When the hook is inserted into the reinforcing bar, the first inclined surface abuts against the side of the reinforcing bar. When the pressure is continued, the first inclined surface springs back away from the reinforcing bar, and the second inclined surface abuts against the bottom of the reinforcing bar.

[0016] Furthermore, the locking assembly includes two pressure plates disposed on both sides of the fixing plate;

[0017] The pressure plate is connected to the side of the fixed plate by a pin. The pressure plate has an arc-shaped groove with one end open, which drives the pressure plate to rotate relative to the pin. The arc-shaped groove is fastened to the reinforcing bar.

[0018] Furthermore, the two pressure plates are respectively pressed onto the same steel bar from both sides;

[0019] The pressure plate is also provided with mounting holes, and a mounting plate extending downward is provided on one side of the fixing plate. The pressure plate is fixed to the mounting plate by fastening bolts.

[0020] Furthermore, the positioning assembly includes a sleeve fitted onto the flat-lay tube, an adjusting rod screwed onto the sleeve, and a positioning element eccentrically located at the lower end of the adjusting rod.

[0021] The positioning member has an opening groove formed on it, which drives the adjusting rod to rotate. The positioning member is inserted into the reinforcing bar, and the reinforcing bar is located in the opening groove.

[0022] Furthermore, the two adjusting rods are respectively arranged on both sides of the sleeve, and the two positioning members are both inserted into the same reinforcing bar.

[0023] Furthermore, the support member includes a support plate connected to the fixed plate and a support ring disposed on the support plate, wherein the receiving hole is formed on the support ring.

[0024] Furthermore, a rubber sleeve is fixed above the support ring, and the upward-turning tube passes through the rubber sleeve and the support ring.

[0025] Furthermore, the support ring has a rectangular notch, and the support ring is also provided with protrusions on both sides of the notch. The two protrusions are connected by screws. The width of the notch is reduced by tightening the screws with nuts. The upturned tube is located inside the support ring.

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] This embodiment relates to a PVC conduit pre-embedded positioning device, which, as a whole, ... Figures 1 to 2 As shown, the positioning device includes a fixed plate 1, at least two insertion components 2 slidably connected to the fixed plate 1, locking components 3 located on both sides of the fixed plate 1, several support members 4 spaced apart along the length of the fixed plate 1, and several positioning components 5 for limiting the displacement of the flat-lay pipe 10. The insertion components 2 are inserted at the intersection of the reinforcing bars 6. Each insertion component 2 has several elastic clips 201, the inner circumference of which forms an insertion space 202. When the fixed plate 1 is pushed closer to the reinforcing bars 6, the elastic clips 201 deform to expand the insertion space 202. When the intersection of the reinforcing bars 6 is located within the insertion space 202, the elastic clips 201 spring back and abut against the reinforcing bars 6. The locking components 3 are driven to abut against the adjacent reinforcing bar 6, limiting the displacement of the fixed plate 1. The support members 4 have accommodating holes 403 formed within them for placing the upturned pipe 9.

[0050] According to the above design, the PVC conduit pre-embedded positioning device of this embodiment fixes the fixing plate 1 in the laid lower layer of steel bars 6 by setting the plug-in component 2, and locks it on the same steel bar 6 by locking the locking component 3, thereby ensuring the stability of the fixing plate 1, thus ensuring the accurate positioning of the upturned pipe 9 set in the support member 4. At the same time, the positioning component 5 fixes the flat pipe 10 to the lower layer of steel bars 6, ensuring the positioning accuracy and firmness of the flat pipe 10 and the upturned pipe 9, thereby improving the construction effect of PVC conduit pre-embedded positioning and improving construction efficiency.

[0051] Based on the above overall introduction, this embodiment presents an exemplary structure of the PVC conduit pre-embedded positioning device, such as... Figures 1 to 2 As shown, the fixing plate 1 is formed into a flat plate structure. In order to ensure the perpendicularity of the upward-turning tube 9 to the template, a level 8 is set on the fixing plate 1, which can be adjusted horizontally when the locking assembly 3 is tightened.

[0052] As a preferred embodiment, such as Figures 1 to 3 As shown, the plug-in assembly 2 includes a circular plate 203, a sliding post 204 connected to the circular plate 203, and a baffle 205 disposed on the sliding post 204. A long groove 101 is provided on the fixed plate 1 along its length direction, the sliding post 204 is disposed within the long groove 101, and the baffle 205 is disposed above the fixed plate 1. Four elastic clips 201 are evenly distributed around one end of the circular plate 203, and the spacing between two adjacent elastic clips 201 is adapted to the diameter of the reinforcing bar 6.

[0053] Furthermore, such as Figure 1 and Figure 3As shown, the elastic card 201 has a hook 206 bent towards the insertion space 202 on the side away from the circular plate 203. The hook 206 has a first inclined surface 2061 and a second inclined surface 2062. When the hook 206 is inserted into the reinforcing bar 6, the first inclined surface 2061 abuts against the side of the reinforcing bar 6. When pressure is continued, the first inclined surface 2061 springs back away from the reinforcing bar 6, and the second inclined surface 2062 abuts against the bottom of the reinforcing bar 6. The thickness between the hook 206 and the circular plate 203 is equal to the diameter of the two reinforcing bars 6. After pouring, this pre-embedded positioning device is fixed in the concrete, ensuring the positioning accuracy of the entire PVC conduit.

[0054] In addition, such as Figures 1 to 4 As shown, the locking assembly 3 includes two pressure plates 301 disposed on both sides of the fixed plate 1. The pressure plates 301 are connected to the side of the fixed plate 1 by a pin 305. The pressure plates 301 are provided with an arc-shaped groove 302 with one end open, which drives the pressure plates 301 to rotate relative to the pin 305. The arc-shaped groove 302 is engaged with the reinforcing bar 6.

[0055] Preferably, as Figures 1 to 4 As shown, two pressure plates 301 are respectively pressed onto the same reinforcing bar 6 from both sides. The pressure plates 301 are also provided with mounting holes 303. A downwardly extending mounting plate 7 is provided on one side of the fixing plate 1. The pressure plates 301 are fixed to the mounting plate 7 by fastening bolts 304. The mounting plate 7 is a flat plate on one side of the reinforcing bar 6. The two pressure plates 301 are rotated in opposite directions until the arc-shaped groove 302 abuts against the reinforcing bar 6, and are fastened to the mounting plate 7 by fastening bolts 304. The mounting plate 7 is provided with threaded holes. The locking of the reinforcing bar 6 by the two pressure plates 301 increases the connection stability of the fixing plate 1. The horizontality can be adjusted before the pressure plates 301 are tightened. The tightening at both the locking assembly 3 and the plug-in assembly 2 increases the positioning accuracy of the upward-turning tube 9.

[0056] As a preferred embodiment, such as Figures 5 to 7 As shown, the positioning assembly 5 includes a sleeve 501 fitted onto the flat pipe 10, an adjusting rod 502 screwed onto the sleeve 501, and a positioning element 503 eccentrically located at the lower end of the adjusting rod 502. The positioning element 503 has an opening groove 504 formed thereon, which drives the adjusting rod 502 to rotate. The positioning element 503 is inserted into the reinforcing bar 6, and the reinforcing bar 6 is located within the opening groove 504.

[0057] Furthermore, such as Figures 5 to 7 As shown, two adjusting rods 502 are respectively set on both sides of the sleeve 501, and two positioning parts 503 are inserted into the same reinforcing bar 6. By rotating the two adjusting rods 502, the two positioning parts 503 are respectively inserted into the same reinforcing bar 6, thereby positioning the flat pipe 10. The positioning operation is simple and does not require steel wire binding as in the prior art, thus improving the operation efficiency.

[0058] In addition, such as Figures 1 to 2 As shown, the support member 4 includes a support plate 401 connected to the fixed plate 1, and a support ring 402 disposed on the support plate 401, with a receiving hole 403 formed on the support ring 402. In this embodiment, the support ring 402 is formed into a circular shape, and the diameter of the receiving hole 403 is adapted to the outer diameter of the upturned tube 9.

[0059] Preferably, such as Figures 1 to 2 As shown, a rubber sleeve 404 is fixed above the support ring 402, and the upturning tube 9 passes through the rubber sleeve 404 and the support ring 402. By setting the rubber sleeve 404, the displacement of the upturning tube 9 can be limited by friction.

[0060] To further ensure the tightness of the upward-facing pipe 9, such as Figure 2 As shown, the support ring 402 has a rectangular notch 4021, and the support ring 402 also has protrusions 405 located on both sides of the notch. The two protrusions 405 are connected by screws 406. The screws 406 are tightened by nuts 407, which reduces the width of the notch. The upturned tube 9 is located inside the support ring 402. A manual wrench drives the nuts 407 to rotate, which reduces the distance between the two protrusions 405, thereby increasing the friction between the sleeve 501 and the upturned tube 9 and improving the positioning stability of the upturned tube 9.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
