Description

Technical Field

[0001] The invention belongs to the technical field of industrial and civil construction, and in particular is a floor thickness controller of a pre-embedded hanger rod. Background Art

[0002] The existing floor thickness controller can control the floor thickness, but cannot control the flatness of the floor surface. During the concrete pouring process, the floor formwork will sink, and the controller top surface elevation will produce errors, so that the flatness of the floor concrete surface cannot meet the specification requirements.

[0003] The existing ceiling installation method is to install expansion bolts and hangers after drilling, and then install keels and gypsum boards. When the gypsum ceiling is exposed to moisture, the weight increases, which always causes the hanger expansion bolts to be overwhelmed and fall and injure people. Ordinary hanger expansion bolts adopt the post-drilling construction process. The hanger is M8 and the expansion bolt drilling diameter is M12. The main force mode is to pull the expansion bolt head when tightening it, and squeeze the expansion bolt casing and the hole wall to generate friction.

[0004] Since the expansion bolt sleeve is made of metal, it will rust over time and lose friction. The longer the time, the greater the loss of tensile strength. The expansion bolt installation process is a ceiling installation, which is not easy to operate manually. The drilling depth and the expansion bolt installation depth may not be in place, resulting in insufficient pull-out resistance of the expansion bolt. The pre-buried wire pipe is often hit during drilling. Most of the wire pipes are energized during later decoration, which may cause electric shock accidents. Or the wire pipe is damaged during drilling, causing blockage of the wire pipe, making it impossible to lay the cable, and burrs on the edge of the damaged wire pipe. During the cable laying process, the cable skin is damaged, causing a short circuit. Therefore, a floor thickness controller for pre-buried hangers is proposed. Summary of the invention

[0008] Preferably, the boom expansion bolt comprises a positioning plate, a boom expansion bolt sleeve, a pull head and a positioning sleeve; The positioning plate is fixedly installed on the other side of the floor thickness controller column, the hanger expansion bolt sleeve is movably installed inside the positioning plate, the pull head is movably installed on the top of the hanger expansion bolt sleeve, and the positioning sleeve is fixedly installed inside the base of the floor thickness controller and is located at the bottom of the hanger expansion bolt sleeve.

[0009] Preferably, the height-adjustable threaded plastic cover is internally movably equipped with an extrusion assembly located below the feed pipe, and the extrusion assembly includes a fixed sleeve, an extrusion piston and an air storage tank; The fixed sleeve is movably installed in the inner cavity of the height-adjustable threaded plastic cover and is located below the feed pipe. The extrusion piston is movably installed inside the fixed sleeve. The air storage groove is opened inside the fixed sleeve and is located outside the extrusion piston.

[0010] Preferably, a locking assembly between the air storage groove and the fixed sleeve is provided inside the fixed sleeve, and the locking assembly includes a locking block, a first pneumatic groove and a first pneumatic piston rod; The locking block is movably installed inside the outer side of the extrusion piston, the first pneumatic groove is opened inside the extrusion piston and is located outside the locking block, the first pneumatic piston rod is movably installed in the inner cavity of the first pneumatic groove, and the inner end is fixedly connected to the outer side of the locking block.

[0011] Preferably, an unlocking assembly located directly below the locking block is disposed inside the fixed sleeve, and the unlocking assembly includes a second pneumatic groove, a second pneumatic piston rod and a venting groove; The second pneumatic groove is opened inside the fixed sleeve and is located directly below the first pneumatic groove. The second pneumatic piston rod is movably installed inside the second pneumatic groove. The second pneumatic groove is connected to the first pneumatic groove through the ventilation groove.

[0012] Preferably, a ventilation valve flap is provided inside the fixed sleeve and is located directly above the air storage groove.

[0013] Preferably, a second exhaust groove is provided on the top of the height-adjustable threaded plastic cover.

[0014] Preferably, a second exhaust groove is provided on the outer side of the height-adjusting threaded column, and an exhaust assembly located on the inner side of the second exhaust groove is provided on the top of the height-adjusting threaded column.

[0015] Preferably, the exhaust assembly includes a trigger column, a second elastic member, a blocking ring block and a blocking plate; The trigger column is movably installed in the middle of the top of the height-adjusting threaded column. The trigger column is elastically connected to the inner wall of the top of the height-adjusting threaded column through a second elastic member. The blocking ring block is arranged on the outside of the trigger column and located inside the second exhaust groove. The blocking plate is arranged inside the second exhaust groove and located above the outer end of the blocking ring block.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The above technical solution is to set a height-adjustable threaded plastic cover, a hanger expansion bolt and a one-way valve. Through the design of the hanger expansion bolt, it can be directly embedded and installed for protection after the concrete is poured. Afterwards, a tool can be used to drive the height-adjustable threaded plastic cover to move up and down as a whole through the groove to adjust the floor elevation so as to keep the floor flat. During the pouring process, the concrete will push the one-way valve in opposite directions through the feed pipe to enter the gap between the height-adjustable threaded plastic cover and the extrusion assembly until the concrete is full, thereby avoiding the internal gap of the height-adjustable threaded plastic cover affecting the overall strength of the floor.

[0017] The present invention provides a locking block and a second pneumatic piston rod. When the fixed sleeve and the extrusion piston are pushed downward as a whole, the second pneumatic piston rod will contact the top of the height-adjusting threaded column and push the gas inside the second pneumatic groove upward to the inner cavity of the first pneumatic groove through the ventilation groove, so as to push the two first pneumatic piston rods and the locking block to move in opposite directions, release the fixing effect on the extrusion piston as a whole, and make the compressed gas in the inner cavity of the fixed sleeve and the height-adjusting threaded column smoothly push the extrusion piston as a whole to move upward through the air storage groove, so as to extrude the top concrete and make it compacted. The bubbles will be discharged through the second exhaust groove, so that the strength of the concrete filled in the height-adjusting threaded plastic cover can be smoothly increased.

[0018] The present invention provides a trigger column and a blocking ring block. When the concrete on the top of the extrusion piston is full, the extrusion piston will smoothly squeeze downward to push the trigger column and the blocking ring block downward as a whole, so that the blocking ring block and the blocking plate are separated and the blocking effect on the second exhaust groove is released. At this time, the compressed gas in the air storage groove will be smoothly discharged through the second exhaust groove. When the air pressure in the air storage groove disappears, the bottom of the ventilation valve disc will be released, and concrete will enter the air storage groove and the second exhaust groove through the ventilation valve disc to be filled, so that the interior of the height-adjusting threaded plastic cover is completely filled with concrete, which effectively avoids the influence of bubbles on the strength.

DETAILED DESCRIPTION

[0021] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 8As shown, the present invention provides a floor thickness controller with embedded hangers, including a floor thickness controller base 1; a floor thickness controller column 2, which is arranged in the middle of the top of the floor thickness controller base 1, and a floor thickness controller bottom steel bar support plate 3 is arranged on one side of the floor thickness controller column 2; an elevation adjustment component 5, which is arranged at the top of the floor thickness controller column 2; a hanger expansion bolt 6, which is arranged at the top of the floor thickness controller base 1 and is located on the other side of the floor thickness controller column 2; a concrete one-way inlet valve 7, which includes a feed pipe 701, which is fixedly installed on the outer side of the top of the inner cavity of the elevation adjustment component 5, and a one-way valve 702 is movably installed inside the feed pipe 701, and the one-way valve 702 is elastically connected to the inner wall of the feed pipe 701 through a first elastic member 703.

[0023] Since the elastic force of the first elastic member 703 only pushes the two one-way valves 702 to move in opposite directions, the external concrete can only enter the inner cavity of the height-adjustable threaded plastic cover 502 by pushing the one-way valves 702 in opposite directions and cannot be discharged, so that the concrete is smoothly filled inside.

[0024] like Figure 1 and Figure 3 As shown, a floor thickness controller fixing hole 4 is provided on the outer side of the bottom of the floor thickness controller base 1, and the elevation adjustment component 5 includes an adjustment threaded column 501, an adjustment threaded plastic cover 502 and a groove 503; The height-adjusting threaded column 501 is fixedly installed on the top of the floor thickness controller column 2 , the height-adjusting threaded plastic cover 502 is threadedly sleeved on the surface of the height-adjusting threaded column 501 , and the groove 503 is opened on the top of the height-adjusting threaded plastic cover 502 .

[0025] With the above solution, by providing the groove 503 , an operator can use a cross screwdriver to drive the height-adjusting threaded plastic cover 502 to rotate up and down on the surface of the height-adjusting threaded column 501 through the groove 503 , so as to adjust the floor elevation smoothly.

[0026] like Figure 2 As shown, the boom expansion bolt 6 includes a positioning plate 601, a boom expansion bolt sleeve 602, a pull head 603 and a positioning sleeve 604; The positioning plate 601 is fixedly installed on the other side of the floor thickness controller column 2, the hanger expansion bolt sleeve 602 is movably installed inside the positioning plate 601, the pull head 603 is movably installed on the top of the hanger expansion bolt sleeve 602, and the positioning sleeve 604 is fixedly installed inside the floor thickness controller base 1 and is located at the bottom of the hanger expansion bolt sleeve 602.

[0027] The above solution is adopted: by providing the pull-out head 603 and designing the pull-out head 603 , the top of the hanger expansion bolt sleeve 602 can be sealed to prevent concrete from entering and withstand the pressure of the concrete.

[0028] The operator can first position and insert the hanger expansion bolt sleeve 602 between the inner side of the positioning plate 601 and the top of the positioning sleeve 604, and then clamp the pull head 603 on the top of the hanger expansion bolt sleeve 602, and then use a tool to drive the overall upper and lower elevation adjustment of the threaded plastic cover 502 through the groove 503 until it reaches a suitable height. Then, the concrete can be poured on the floor mold, and the entire hanger expansion bolt 6 will be directly buried for protection.

[0029] like Figure 3 and Figure 7 As shown, the height-adjustable threaded plastic cover 502 is internally movably installed with an extrusion assembly 8 located below the feed pipe 701, and the extrusion assembly 8 includes a fixed sleeve 801, an extrusion piston 802 and an air storage tank 803; The fixed sleeve 801 is movably installed in the inner cavity of the height-adjustable threaded plastic cover 502 and is located below the feed pipe 701 . The extrusion piston 802 is movably installed inside the fixed sleeve 801 . The air storage groove 803 is opened inside the fixed sleeve 801 and is located outside the extrusion piston 802 .

[0030] By adopting the above solution: by providing an air storage groove 803, when the fixed sleeve 801 and the extrusion piston 802 are downward as a whole, the gas in the cavity between the fixed sleeve 801 and the height-adjusting threaded column 501 can be compressed and accumulated in the air storage groove 803 for storage.

[0031] like Figure 5 As shown, the fixed sleeve 801 is provided with an air storage groove 803 and a locking assembly 9 between the fixed sleeve 801, and the locking assembly 9 includes a locking block 901, a first pneumatic groove 902 and a first pneumatic piston rod 903; The locking block 901 is movably installed inside the outer side of the extrusion piston 802. The first pneumatic groove 902 is opened inside the extrusion piston 802 and is located outside the locking block 901. The first pneumatic piston rod 903 is movably installed in the inner cavity of the first pneumatic groove 902, and the inner end is fixedly connected to the outer side of the locking block 901.

[0032] By adopting the above solution, when the two locking blocks 901 are completely stuck inside the outer side of the extrusion piston 802 , the extrusion piston 802 can be smoothly fixed and locked inside the fixed sleeve 801 .

[0033] like Figure 5As shown, the interior of the fixed sleeve 801 is provided with an unlocking assembly 11 located just below the locking block 901, and the unlocking assembly 11 includes a second pneumatic groove 1101, a second pneumatic piston rod 1102 and a venting groove 1103; The second pneumatic groove 1101 is opened inside the fixed sleeve 801 and is located directly below the first pneumatic groove 902 . The second pneumatic piston rod 1102 is movably installed inside the second pneumatic groove 1101 . The second pneumatic groove 1101 is connected to the first pneumatic groove 902 through the ventilation groove 1103 .

[0034] The above solution is adopted: by providing a second pneumatic piston rod 1102, when the second pneumatic piston rod 1102 is squeezed by the top of the raised threaded plastic cover 502 and retracted upward into the inner cavity of the second pneumatic groove 1101, the internal gas of the second pneumatic groove 1101 will be introduced into the interior of the first pneumatic groove 902 through the ventilation groove 1103.

[0035] like Figure 4 and Figure 7 As shown, a ventilation valve flap 10 is disposed inside the fixed sleeve 801 and is located directly above the air storage groove 803 .

[0036] The above scheme is adopted: through the design of the ventilation valve flap 10, the gas at the top of the fixed sleeve 801 and inside the air storage groove 803 can be blocked. When the air pressure at the bottom of the ventilation valve flap 10 disappears, the concrete on the top of the ventilation valve flap 10 will impact the ventilation valve flap 10 to open and flow into the air storage groove 803 for replenishment.

[0037] like Figure 6 As shown, a second exhaust groove 13 is provided on the top of the height-adjustable threaded plastic cover 502 .

[0038] By adopting the above solution, by providing the second exhaust groove 13, when the extrusion piston 802 squeezes the concrete upward, the concrete will be compacted and the internal bubbles will be discharged smoothly through it.

[0039] like Figure 6 and Figure 8 As shown, a second exhaust groove 13 is provided on the outer side of the height-adjusting threaded column 501 , and an exhaust component 14 located on the inner side of the second exhaust groove 13 is provided on the top of the height-adjusting threaded column 501 .

[0040] By adopting the above solution: by providing the second exhaust groove 13, when the exhaust component 14 releases the blockage of the second exhaust groove 13, the compressed gas inside the air storage tank 803 can be discharged through the second exhaust groove 13, and concrete can also enter the interior for filling.

[0041] like Figure 6 and Figure 8As shown, the exhaust assembly 14 includes a trigger column 1401, a second elastic member 1402, a blocking ring block 1403 and a blocking plate 1404; The trigger column 1401 is movably installed in the middle of the top of the height-adjusting threaded column 501. The trigger column 1401 is elastically connected to the inner wall of the top of the height-adjusting threaded column 501 through the second elastic member 1402. The blocking ring block 1403 is arranged on the outside of the trigger column 1401 and is located inside the second exhaust groove 13. The sealing plate 1404 is arranged inside the second exhaust groove 13 and is located above the outer end of the blocking ring block 1403.

[0042] The above solution is adopted: by providing a blocking ring block 1403, when the top of the trigger column 1401 is squeezed and pushed downward, the blocking ring block 1403 can be synchronously moved downward to form a gap between the blocking plate 1404, so that the gas can be discharged smoothly, and at the same time concrete can enter the interior.

[0043] First, the operator can position and insert the hanger expansion bolt sleeve 602 between the inner side of the positioning plate 601 and the top of the positioning sleeve 604, and then clamp the pull head 603 on the top of the hanger expansion bolt sleeve 602. Then, the operator can use the tool to adjust the overall upper and lower elevation of the threaded plastic cover 502 through the groove 503 until it reaches the appropriate height. Then, the concrete can be poured on the floor mold, and the entire hanger expansion bolt 6 will be directly buried for protection.

[0044] After that, the poured concrete will push the one-way valve 702 through the feed pipe 701 to enter the inner cavity of the height-adjusting threaded plastic cover 502 in opposite directions, thereby pushing the fixed sleeve 801 and the extrusion piston 802 to move downward as a whole, until the top of the height-adjusting threaded column 501 pushes the second pneumatic piston rod 1102 to retract upward into the inner cavity of the second pneumatic groove 1101, so that the gas inside the second pneumatic groove 1101 is pushed through the ventilation groove 1103 and introduced into the inner cavity of the first pneumatic groove 902. The air pressure in the inner cavity becomes larger, which can smoothly push the first pneumatic piston rod 903 and the locking block 901 to move in opposite directions until they are completely The fixing effect on the entire extrusion piston 802 is released. Since the inner cavity gap of the second pneumatic piston rod 1102 is much larger than the first pneumatic groove 902, when the second pneumatic piston rod 1102 is not fully inserted into the second pneumatic groove 1101, the extrusion piston 802 will be released, and the gas between the extrusion piston 802 and the height adjustment threaded column 501 will push the extrusion piston 802 upward through the air storage groove 803 to avoid contact with the top of the trigger column 1401. Subsequently, the top concrete can be squeezed upward by the extrusion piston 802, and the bubbles are discharged through the second exhaust groove 13, making the concrete more compact.

[0045] When the concrete on the top of the extrusion piston 802 is slowly filled, the extrusion piston 802 will be pushed downward to reset, so as to push the trigger column 1401 and the blocking ring block 1403 downward synchronously, so that a gap is generated between the blocking ring block 1403 and the sealing plate 1404, and the compressed gas in the air storage groove 803 will be smoothly discharged through the second exhaust groove 13, and the concrete will simultaneously push the ventilation valve flap 10 to open and fill the air storage groove 803 and the second exhaust groove 13. At this time, the compressed gas in the air storage groove 803 will be smoothly discharged through the second exhaust groove 13, and the concrete will enter the air storage groove 803 and the second exhaust groove 13 through the ventilation valve flap 10 to be filled.
