Description

Technical Field

[0001] The utility model relates to the technical field of formwork support frames, in particular to a structure for erecting a formwork support frame by using profiled steel. Background Technique

[0002] For the support of thick and large formworks, existing methods mostly use industrial I-beams or channel steels with high bearing capacity as formwork support frames. The formwork support frame has multiple support units, and each support unit is composed of at least two profiled steels serving as legs and a channel steel serving as the top support at the bottom of the formwork. The profiled steel is installed and fixed on the top of the channel steel through multiple bolts and other connecting pieces for support, and the channel steel is attached to the bottom of the thick formwork for support.

[0003] The existing formwork support frame erected by using profiled steel has the following deficiencies in use: 1. The channel steel is installed and fixed to the profiled steel through multiple fixing bolts, and the fixing and disassembly are relatively cumbersome, and the disassembly and assembly efficiency is low; 2. After assembly, the top support height cannot be flexibly adjusted according to the use requirements. When a long thick formwork requires multiple support units, it is inevitable that due to the lower installation and fixation, the height cannot be guaranteed to be consistent, resulting in the phenomenon that some support baffles cannot stably fit and support the bottom of the thick formwork, and the use flexibility is not ideal. In view of this, this application proposes a structure for erecting a formwork support frame by using profiled steel. Content of the Utility Model

[0004] The purpose of the utility model is to provide a structure for erecting a formwork support frame by using profiled steel to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A structure for erecting a formwork support frame by using profiled steel, including a horizontally arranged U-shaped channel steel. A relative horizontal driving mechanism is threadedly fixed on the inner wall of the top of the U-shaped channel steel. Two inclined support mechanisms are in movable contact with the inner wall of the top of the U-shaped channel steel. The two inclined support mechanisms are used to support the U-shaped channel steel, and the relative horizontal driving mechanism is used to drive the two inclined support mechanisms to rotate away from or close to each other to appropriately adjust the support height of the U-shaped channel steel.

[0006] The relative horizontal driving mechanism includes a rectangular box threadedly fixed on the inner wall of the top of the U-shaped channel steel. Two L-shaped rods are arranged inside the U-shaped channel steel. The rectangular box is slidably sleeved on the two L-shaped rods. A misaligned relative linkage driving assembly is rotatably connected between the inner walls on both sides of the rectangular box. Both L-shaped rods are threadedly sleeved on the misaligned relative linkage driving assembly, and the misaligned relative linkage driving assembly is used to drive the two L-shaped rods to move away from or close to each other.

[0007] The diagonal bracing mechanism includes an I-beam arranged obliquely. A fixed seat is hinged to the bottom of the I-beam, and an anti-wear top support assembly is hinged to the top of the I-beam. The L-shaped rod is clamped on the corresponding anti-wear top support assembly. The two anti-wear top support assemblies are used to drive the two I-beams to rotate closer or away from each other to change the slope when the two L-shaped rods move away from or close to each other, and use the I-beam whose slope is changed by rotation to change the support height at the top, so as to achieve the effect of appropriately adjusting the top support height. In the way that the top support height is adjustable, when using multiple sets of this device to support multiple templates, the effect that the bottom of the template cannot be stably supported due to height error can be avoided.

[0008] Preferably, the offset relative coupling drive assembly includes two screw rods arranged side by side up and down. The two screw rods are respectively rotatably installed on the inner walls of the two sides of the rectangular box. The thread directions of the two screw rods are opposite. The two L-shaped rods are respectively thread sleeved on the corresponding screw rods. A rotating shaft located between the two screw rods is rotatably connected between the inner walls of the two sides of the rectangular box. Two first gears are fixedly sleeved on the rotating shaft. A second gear is meshed on the outer side of each of the two first gears. The two second gears are respectively fixedly sleeved on the corresponding screw rods. A drive motor with an output shaft fixedly connected to the left end of the lower screw rod is embedded and fixed at the bottom left of the rectangular box.

[0009] Preferably, the anti-wear top support assembly includes an L-shaped moving seat hinged to the top end of the corresponding I-beam. The two L-shaped moving seats are symmetrically arranged. Four balls are movably nested in a rectangular shape at the top of the L-shaped moving seat. The top of the balls is in movable contact with the inner wall of the top of the U-shaped channel steel.

[0010] Preferably, a storage battery electrically connected to the drive motor is fixedly installed on the left inner wall of the rectangular box. A wireless remote control switch is fixedly connected and electrically connected to the front side of the drive motor. The wireless remote control switch is matched with an external remote controller.

[0011] Preferably, rectangular clamping holes are formed on the mutually repulsive sides of the two L-shaped rods. The rectangular clamping holes are movably sleeved on the corresponding rectangular clamping sleeves. A threaded hole is formed on the bottom inner wall of the rectangular clamping hole. A knob-type bolt is thread sleeved in the threaded hole. The rectangular clamping sleeve is movably sleeved on the knob-type bolt.

[0012] Preferably, four bolt installation through holes are formed in a rectangular shape on the top of the fixed seat. Two circular sleeves are fixedly connected to the mutually repulsive sides of the two I-beams. With the provided circular sleeves, when using multiple sets of this device for support work, for multiple circular sleeves that are opposite front and back, the integrity between multiple sets of this device can be strengthened by inserting the same steel pipe into them.

[0013] Preferably, two threaded grooves are provided on both sides of the top of the rectangular box, two first grooves are provided on the top of the U-shaped steel channel, two bolt through holes are provided on the bottom inner wall of the first groove, fixing bolts are threadedly sleeved in the threaded grooves, and the bolt through holes are movably sleeved on the corresponding fixing bolts.

Through the cooperation of the L-shaped rod, anti-wear top support assembly, rectangular clamping hole and knob-type bolt, the two diagonal bracing mechanisms can be conveniently disassembled and assembled with the U-shaped steel channel by simply locking with the knob-type bolt through clamping fit, without using multiple fixing bolts for installation, fixing and disassembly work.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1 to 4 shown, the formwork support frame erection structure using section steel proposed in this embodiment includes a horizontally arranged U-shaped channel steel 2. A relative horizontal driving mechanism is threadedly fixed on the inner wall of the top of the U-shaped channel steel 2. Two inclined support mechanisms are in movable contact with the inner wall of the top of the U-shaped channel steel 2. The two inclined support mechanisms are used to support the U-shaped channel steel 2. The relative horizontal driving mechanism is used to drive the two inclined support mechanisms to rotate away from or close to each other to appropriately adjust the support height of the U-shaped channel steel 2;

[0025] The relative horizontal driving mechanism includes a rectangular box 3 threadedly fixed on the inner wall of the top of the U-shaped channel steel 2. Wherein, two threaded grooves are opened on both sides of the top of the rectangular box 3. Two first grooves are opened on the top of the U-shaped channel steel 2. Two bolt through holes are opened on the inner wall of the bottom of the first groove. Fixed bolts are threadedly sleeved in the threaded grooves. The bolt through holes are movably sleeved on the corresponding fixed bolts, achieving the effect of threadedly fixing the rectangular box 3 to the U-shaped channel steel 2. Using the threaded fixing method, it is convenient to disassemble the rectangular box 3 when loosening the fixed bolts later. Two L-shaped rods 301 are arranged inside the U-shaped channel steel 2. The rectangular box 3 is slidably sleeved on the two L-shaped rods 301. Wherein, rectangular guide holes are opened on both inner walls of the rectangular box 3, and the inner walls of the rectangular guide holes are slidably sleeved on the outer sides of the corresponding L-shaped rods 301, achieving the effect of guiding the horizontal sliding of the L-shaped rods 301. A misaligned relative coupling driving assembly is rotatably connected between the two inner walls of the rectangular box 3. The two L-shaped rods 301 are both threadedly sleeved on the misaligned relative coupling driving assembly. The misaligned relative coupling driving assembly is used to drive the two L-shaped rods 301 to move away from or close to each other;

[0026] The diagonal bracing mechanism includes an I-beam 1 arranged obliquely. A fixed seat 101 is hinged to the bottom of the I-beam 1, and an anti-wear top support assembly is hinged to the top of the I-beam 1. The L-shaped rod 301 is clamped on the corresponding anti-wear top support assembly. Four bolt installation perforations are formed in a rectangular shape at the top of the fixed seat 101. Two circular sleeves 105 are fixedly connected to each of the mutually repulsive sides of the two I-beams 1. With the provided circular sleeves 105, when using multiple such devices for support work, for multiple circular sleeves 105 that are opposite to each other front and back, the integrity between multiple such devices can be strengthened by inserting the same steel pipe into them. The two anti-wear top support assemblies are used to drive the two I-beams 1 to rotate closer or repel each other to change the slope when the two L-shaped rods 301 move closer or repel each other, and use the I-beam 1 whose slope is changed by rotation to change the support height at the top, achieving the effect of appropriately adjusting the top support height. By adjusting the top support height, when using multiple such devices to support multiple templates, the effect of being unable to stably fit and support the bottom of the template due to height errors can be avoided.

[0027] Specifically, the misaligned relative drive assembly includes two screw rods 302 arranged side by side vertically. The two screw rods 302 are respectively rotatably installed on the inner walls of both sides of the rectangular box 3. Among them, first bearings are fixedly connected to the inner walls of both sides of the rectangular box 3, and the inner ring of the first bearing is fixedly sleeved on the outer side of the corresponding screw rod 302, achieving the effect of rotatably installing the screw rod 302. The thread directions of the two screw rods 302 are opposite. Two L-shaped rods 301 are respectively threadedly sleeved on the corresponding screw rods 302. Among them, threaded grooves are opened at the ends of the two L-shaped rods 301, and the threaded grooves are threadedly connected to the corresponding screw rods 302. By using the threaded connection relationship between the screw rod 302 and the threaded groove, and matching the opposite thread directions of the two screw rods 302, it achieves the effect of conveniently driving the two L-shaped rods 301 to move away from or close to each other when the two screw rods 302 rotate. A rotating shaft 303 located between the two screw rods 302 is rotatably connected between the inner walls of both sides of the rectangular box 3. Two first gears 305 are fixedly sleeved on the rotating shaft 303. A second gear 304 is meshed with the outer side of each of the two first gears 305. The two second gears 304 are respectively fixedly sleeved on the corresponding screw rods 302. A drive motor 306 with an output shaft fixedly connected to the left end of the lower screw rod 302 is fixedly installed and embedded at the bottom left of the rectangular box 3. A storage battery electrically connected to the drive motor 306 is fixedly installed on the left inner wall of the rectangular box 3. A wireless remote control switch is fixedly and electrically connected to the front side of the drive motor 306. The wireless remote control switch is matched with an external remote control, achieving the effect of conveniently remotely controlling the opening and closing of the drive motor 306; the arranged screw rod 302, rotating shaft 303, first gear 305, second gear 304 and drive motor 306 cooperate. By using the drive motor 306 to drive the lower screw rod 302 to rotate, the lower screw rod 302 drives the lower second gear 304 to rotate. The lower second gear 304 drives the upper screw rod 302 to rotate synchronously through the first gear 305 on the left, the rotating shaft 303 and the second gear 304 on the upper side in sequence. The rotation of the two screw rods 302 drives the two L-shaped rods 301 to move close to or away from each other.

[0028] Further, the anti-wear top support assembly includes an L-shaped moving seat 102 hinged to the top end of the corresponding I-beam 1. The two L-shaped moving seats 102 are symmetrically arranged. Four balls 103 are movably nested in a rectangular shape at the top of the L-shaped moving seat 102. The top of the balls 103 is in movable contact with the inner wall of the top of the U-shaped channel steel 2. A rectangular clamping sleeve 104 is fixedly connected to one side of the two L-shaped moving seats 102 close to each other. The L-shaped rod 301 is clamped on the corresponding rectangular clamping sleeve 104. The L-shaped moving seat 102, the balls 103 and the rectangular clamping sleeve 104 are matched. By moving the two L-shaped rods 301 closer or away from each other, the two L-shaped moving seats 102 are driven to move closer or away from each other. The L-shaped moving seat 102 drives the corresponding balls 103 to move on the inner wall of the top of the U-shaped channel steel 2. The moving friction is reduced by the balls 103. The L-shaped moving seat 102 drives the corresponding I-beam 1 to rotate to change the inclination, so that the height of its top end changes and drives the height change of the L-shaped moving seat 102, thereby realizing the change of the top support height of the U-shaped channel steel 2.

[0029] Further, rectangular clamping holes are formed on one side of the two L-shaped rods 301 that repel each other. The rectangular clamping holes are movably sleeved on the corresponding rectangular clamping sleeves 104. A threaded hole is formed on the bottom inner wall of the rectangular clamping hole. A knob-type bolt 307 is threadedly sleeved in the threaded hole. The rectangular clamping sleeve 104 is movably sleeved on the knob-type bolt 307, achieving the effect of threadedly locking the rectangular clamping sleeve 104. When the knob-type bolt 307 is rotated reversely and moved downward subsequently, the locking state of the rectangular clamping sleeve 104 can be released, facilitating the movement of the L-shaped moving seat 102 to drive the rectangular clamping sleeve 104 to separate from the L-shaped rod 301. This serves to facilitate the subsequent separation of the two diagonal bracing mechanisms from the U-shaped channel steel 2 for disassembly and transportation, ensuring the convenience of transportation before and after use.

[0030] The usage method of this embodiment is as follows: After being fixed at the bottom, it is necessary to adjust the top support height of the U-shaped steel channel 2 according to the height of the heavy template, or when multiple sets of this device are required due to the long length of the heavy template, and when there are gaps because the bottom installation heights of some of the U-shaped steel channels 2 are inconsistent and cannot fit with the bottom of the heavy template, the operator uses an external remote control to operate the wireless remote control switch to control the corresponding driving motor 306 to start forward. The driving motor 306 drives the lower screw 302 to rotate. The lower screw 302 drives the lower second gear 304 to rotate. The lower second gear 304 drives the upper screw 302 to rotate synchronously through the first gear 305 on the left, the rotating shaft 303, the first gear 305 on the right, and the upper second gear 304 in sequence. Since the thread helix directions of the two screws 302 are opposite, when the two screws 302 rotate, they drive the two L-shaped rods 301 to move away from each other. The two L-shaped rods 301 drive the two L-shaped moving seats 102 to move away from each other. The L-shaped moving seat 102 drives the corresponding ball 103 to move on the inner wall of the top of the U-shaped steel channel 2. The ball 103 is used to reduce the moving friction. The two L-shaped moving seats 102 drive the two I-shaped steels 1 to rotate away from each other to change the inclination angle, so that the height of their tops changes and drives the L-shaped moving seat 102 to move upward. The two L-shaped moving seats 102 drive the U-shaped steel channel 2 to move upward through eight balls 103, so that its height changes, achieving the effect of flexibly and appropriately adjusting the top support height according to the usage requirements. Moreover, by using the method of adjustable top support height, when using multiple sets of this device for top support, it can avoid the phenomenon that some of the U-shaped steel channels 2 cannot stably fit and support the bottom of the heavy template, improving the usage flexibility and stability;

[0031] During subsequent disassembly and transportation, the operator directly rotates the knob-type bolt 307 in the reverse direction to make it move downward and separate from the rectangular sleeve 104, releasing the locking of the rectangular sleeve 104. Then, the L-shaped moving seat 102 can be moved to drive the corresponding rectangular sleeve 104 to separate from the L-shaped rod 301, realizing the disassembly of the inclined support mechanism and the U-shaped steel channel 2. During assembly, the L-shaped moving seat 102 is moved to drive the rectangular sleeve 104 to be inserted into the corresponding rectangular card hole, and the knob-type bolt 307 is rotated forward to make it move upward and snap into the rectangular sleeve 104 to complete the connection and locking. By using the method of simple locking with the knob-type bolt 307 through clamping fit, it is convenient to disassemble and assemble the two inclined support mechanisms and the U-shaped steel channel 2. There is no need to use multiple fixing bolts for installation, fixing, and disassembly work. The operation is simple, improving the disassembly and assembly efficiency. The detachable method facilitates transportation work.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features.
