Description

Technical Field

[0001] This invention relates to the field of pier steel formwork technology, specifically to a connection mechanism based on pier steel formwork. Background Technology

[0002] Pier steel formwork is a standardized formwork used in bridge, building and other engineering projects to pour concrete structures such as bridge piers and columns. It is mainly made of steel and has the characteristics of high strength, high rigidity, high precision and high turnover.

[0003] During the use of pier steel formwork, a connecting mechanism is needed to ensure its fixation. Traditional pier steel formwork connecting mechanisms mostly use snap-fit ​​methods to fix the pier steel formwork. However, the traditional method of fixing the pier steel formwork by snap-fit ​​may lead to loosening of the connecting mechanism. This is because the concrete is vibrated during the pouring process, which generates vibration on the surface of the pier steel formwork. This vibration may cause the connecting mechanism to loosen, thus affecting the stability of the pier steel formwork connecting mechanism. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a connection mechanism based on pier steel formwork, which solves the problem of loosening of the connection mechanism caused by the traditional method of fixing pier steel formwork with snap-fit, thus avoiding affecting the stability of the pier steel formwork connection mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a connection mechanism based on pier steel formwork, comprising two column molds, wherein both the front and rear sides of the two column molds are provided with a plurality of connection components for connection;

[0006] The connecting assembly includes a snap-fit ​​component that snaps onto the surfaces of two column molds. A fixing frame for fixing the structure is fixedly installed on one side of the snap-fit ​​component surface. A rotating frame for rotation is rotatably connected to the inner walls of the fixing frame on both sides. Two connecting hole blocks for connection are rotatably installed on the inner wall of the rotating frame via a shaft. A connecting rod cylinder for connection is fixedly installed on the top surface of the two connecting hole blocks. A tension component for pulling and fixing is provided on the inner wall of the connecting rod cylinder. A pressing component for pressing the snap-fit ​​component is provided on the inner wall of the fixing frame near the snap-fit ​​component.

[0007] Furthermore, the tension assembly includes an L-shaped tie rod slidably mounted on the upper side of the inner wall of the connecting rod cylinder, and the bottom surface of the L-shaped tie rod is slidably connected to the guide groove opened in the inner wall of the connecting rod cylinder through a fixed crossbar. A support cavity for supporting the opening is opened on the upper side of the L-shaped tie rod near the snap-fit ​​component. A conversion cavity is opened at the corner of the L-shaped tie rod. An opening assembly for opening and fixing is provided on the side of the inner wall of the support cavity away from the conversion cavity. A first spring for elastic pushing is sleeved on the wall of the L-shaped tie rod above the crossbar. A disc block for moving is provided below the crossbar. The top surfaces of the disc block are fixedly connected to the bottom surface of the crossbar on opposite sides through fixed damping springs. A first inclined block for tilting and pressing is fixedly installed on the top surface of the disc block through a fixed first connecting square rod.

[0008] Furthermore, the spreading assembly includes a limiting guide rod fixedly installed on one side of the inner wall of the supporting cavity, and a second connecting square rod for movement is slidably installed embedded in the wall of the limiting guide rod. One end of the second connecting square rod penetrates the inner wall of the supporting cavity and is fixedly installed with a second inclined block. A second spring for elastic pushing is sleeved on the wall of the limiting guide rod, and several rotating grooves for rotatable connection are opened on the periphery of the second connecting square rod. A jacking groove block for jacking is rotatably installed on the inner wall of the rotating groove through the rotatably connected connecting inclined block. A support plate for support is fixedly installed on the side of several corresponding jacking groove blocks away from the L-shaped tie rod.

[0009] Furthermore, the extrusion assembly includes two telescopic grooves formed on the surface of the fixing frame near the snap-fit ​​member, and an extrusion rod for extrusion is slidably installed on the inner wall of the telescopic groove, while a positioning tension spring is sleeved on the side of the extrusion rod away from the snap-fit ​​member through a fixed arc-head rod.

[0010] Furthermore, the two column molds are provided with snap-fit ​​interfaces on the top and bottom surfaces and the front and rear sides, and several snap-fit ​​interfaces are circular hole structures. The diameter of several L-shaped tie rods is the same as the size of the inner wall of the snap-fit ​​interface.

[0011] Furthermore, several of the aforementioned snap-fit ​​components are U-shaped block structures, and several corresponding fixing frames are arranged in an alternating manner.

[0012] Furthermore, several of the supporting cavities and corresponding conversion cavities are arranged at the same horizontal position, the upper ends of several of the first springs respectively contact the upper side of the inner wall of the corresponding connecting rod cylinder, and the top surfaces of several of the first connecting square rods respectively penetrate the bottom surfaces of the corresponding crossbar and the corresponding L-shaped tie rod and extend into the interior of the corresponding conversion cavity.

[0013] Furthermore, the inclined surfaces of several second inclined blocks are in sliding contact with the inclined surfaces of corresponding first inclined blocks, and both the first and second inclined blocks are disposed inside the corresponding conversion cavities. Several corresponding support plates are embedded in the surface of the L-shaped tie rod, and several jacking groove blocks extend through the inner wall of the support cavity to the surface of the L-shaped tie rod.

[0014] Furthermore, all of the aforementioned telescopic grooves are square groove structures, and all of the aforementioned extrusion rods are square rod structures. The surface of the extrusion rods is in close contact with the inner wall of the telescopic grooves. Two corresponding arc-head rods extend through the inner wall of the telescopic grooves to the inner wall of the fixing frame. The two ends of several positioning tension springs are fixedly connected to one side of the inner wall of the corresponding telescopic groove and the surface of the extrusion rods. One end of several extrusion rods extends through the surface of the corresponding snap-fit ​​pieces to their interior.

[0015] Furthermore, each of the L-shaped tie rods has a triangular block fixedly installed at its internal corner for reinforcement.

[0016] Compared with the prior art, the present invention provides a connection mechanism based on the steel formwork of the pier body, which has the following advantages:

[0017] 1. The device ensures a firm connection during the connection process and provides a tensile force to reinforce the connection. This helps to offset some of the separation tendency caused by vibration or external force, thus ensuring the stability of the device during use.

[0018] 2. The device utilizes a card interface to ensure the proper connection of the connecting components, and the use of holes and L-shaped tie rods for fixing further ensures the firmness of the column formwork connection process.

[0019] 3. The device utilizes the inclined contact between the first and second inclined blocks to ensure that after the first connecting square rod generates force, the inclined squeezing effect can deliver the thrust to the second connecting square rod, ensuring the structure's expansion effect and increasing the stability of the internal structure of the device.

[0020] 4. The device utilizes a positioning tension spring to ensure that the arc head is positioned within the fixed frame before being compressed. This ensures that the snap-fit ​​connection between the snap-fit ​​component and the column mold is not affected. Only when the snap-fit ​​component is fixed, i.e., when the rotating frame is rotated, will the stable snap-fit ​​connection of the snap-fit ​​component be guaranteed. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 9The connection mechanism based on the pier steel formwork in this embodiment includes two column molds 1. The upper and lower surfaces and the front and rear sides of the two column molds 1 are provided with snap-fit ​​interfaces 101 for snap-fitting. The snap-fit ​​interfaces 101 are all circular hole structures. The front and rear surfaces of the two column molds 1 are provided with several connection components 2 for connection.

[0034] The connecting assembly 2 includes a snap-fit ​​member 201 that snaps onto the surfaces of two column molds 1. A fixing frame 202 for fixing the structure is fixedly installed on one side of the snap-fit ​​member 201. Several snap-fit ​​members 201 are U-shaped block structures. Several corresponding fixing frames 202 are staggered vertically. A rotating frame 203 for rotation is rotatably connected to the inner walls of the fixing frames 202 on both sides. Two connecting hole blocks 205 for connection are rotatably installed on the inner wall of the rotating frame 203 through a shaft 204. A connecting rod cylinder 206 for connection is fixedly installed on the top surface of the two connecting hole blocks 205. A tension component 3 for pulling and fixing is provided on the inner wall of the fixing frame 202 near the snap-fit ​​member 201. A pressing component 4 for pressing the snap-fit ​​member 201 is provided on the inner wall of the fixing frame 202.

[0035] The tension assembly 3 includes an L-shaped pull rod 301 slidably mounted on the upper side of the inner wall of the connecting rod cylinder 206. Triangular blocks 6 are fixedly installed at the corners of several L-shaped pull rods 301 for reinforcement. The triangular blocks 6 ensure that the overall strength of the L-shaped pull rods 301 is not reduced due to the opening, thus guaranteeing the normal function of the L-shaped pull rods 301. The diameter of several L-shaped pull rods 301 is the same as the size of the inner wall of the snap-fit ​​interface 101. The bottom surface of the L-shaped pull rods 301 is slidably connected to the guide groove 303 opened in the inner wall of the connecting rod cylinder 206 through a fixed crossbar 302. A support cavity 304 is opened on the upper side of the L-shaped pull rod 301 near the snap-fit ​​component 201 to support the opening. A conversion cavity 305 is opened at the corner of the L-shaped pull rod 301. Several support cavities 304 and corresponding conversion cavities 305 are at the same level. Positioning: A support assembly 5 for opening and fixing is provided on the side of the inner wall of the support cavity 304 away from the conversion cavity 305. The wall of the L-shaped pull rod 301 is sleeved above the crossbar 302 and a first spring 306 for elastic pushing is sleeved on it. The upper ends of several first springs 306 are respectively in contact with the upper side of the inner wall of the corresponding connecting rod cylinder 206. A movable disc block 307 is provided below the crossbar 302. The top surfaces of the disc block 307 are fixedly connected to the bottom surface of the crossbar 302 on opposite sides by fixed damping springs 308. The top surface of the disc block 307 is fixedly installed with a first inclined block 310 for tilting and pressing by a fixed first connecting square rod 309. The top surfaces of several first connecting square rods 309 respectively penetrate the bottom surfaces of the corresponding crossbar 302 and the corresponding L-shaped pull rod 301 and extend into the interior of the corresponding conversion cavity 305.

[0036] The expansion assembly 5 includes a limiting guide rod 501 fixedly installed on one side of the inner wall of the expansion cavity 304. A second connecting square rod 502 for movement is slidably embedded in the wall of the limiting guide rod 501. This connecting square rod structure prevents the structure from rotating during movement, ensuring normal displacement transmission. One end of the second connecting square rod 502 penetrates the inner wall of the expansion cavity 304 and is fixedly installed with a second inclined block 503. The inclined surfaces of several second inclined blocks 503 respectively slide in contact with the inclined surfaces of corresponding first inclined blocks 310. Both the first inclined blocks 310 and the second inclined blocks 503 are located inside the corresponding conversion cavity 305. The rod 501 is sleeved with a second spring 504 for elastic pushing, and the second connecting square rod 502 is provided with a plurality of rotating grooves 505 for rotatable connection on its periphery. The inner wall of the rotating groove 505 is rotatably mounted with a jacking groove block 507 for jacking through a rotatably connected connecting inclined block 506. The side of the jacking groove block 507 away from the L-shaped tie rod 301 is fixedly mounted with a support plate 508 for support. The jacking groove blocks 507 extend through the inner wall of the support cavity 304 to the surface of the L-shaped tie rod 301. The support plates 508 are embedded in the surface of the L-shaped tie rod 301.

[0037] The extrusion assembly 4 includes two telescopic grooves 401 formed on the surface of the fixing frame 202 near the snap-fit ​​member 201. All of the telescopic grooves 401 are square grooves. The square shape of the telescopic grooves 401 prevents the extrusion rods 402 from rotating. All of the extrusion rods 402 are square rods, and the surface of the extrusion rods 402 is tightly fitted to the inner wall of the telescopic grooves 401. Extrusion rods 402 for extrusion are slidably mounted on the inner wall of the telescopic grooves 401. A positioning tension spring is sleeved on the side of the extrusion rods 402 away from the snap-fit ​​member 201 via a fixed arc-shaped rod 403. 404. The distance that the pressing rod 402 connected to the arc-head rod 403 can move within the snap-fit ​​201 is the arc-head part of the arc-head rod 403. There will not be too much displacement, which can ensure the pressing and fixing effect of the structure inside the snap-fit ​​201. The two corresponding arc-head rods 403 extend through the inner wall of the telescopic groove 401 to the inner wall of the fixing frame 202. The two ends of the several positioning tension springs 404 are respectively fixedly connected to one side of the inner wall of the corresponding telescopic groove 401 and the surface of the pressing rod 402. One end of the several pressing rods 402 extends through the surface of the corresponding snap-fit ​​201 to its interior.

[0038] The working principle of the above embodiments is as follows:

[0039] When the device is in use, the two column molds 1 will combine to form a bridge column structure. The connecting component 2 is used to ensure the stability of the two column molds 1 during use. During use, the connecting component 2 is inserted into the card interface 101 using an L-shaped tie rod 301. Then, the card connector 201 needs to be connected to the surface of the two column molds 1 using a tool. The upper and lower surfaces of the column molds 1 are provided with card interfaces 101, which can ensure that the height of the column molds 1 can be increased. After the height is increased, the connecting component 2 can also be used to connect the height position, which can ensure the applicability of the connecting component 2 of this device.

[0040] After the snap-fit ​​component 201 is snapped into place on the surface of the mold 1, it can be moved closer to the mold 1 by pressing the rotating frame 203. The rotating frame 203 of this device has a handle structure to ensure convenience during installation. During the rotation of the rotating frame 203 around the fixed frame 202, the connecting hole block 205 can pull the connecting rod cylinder 206 under the rotation of the rotating frame 203. At this time, the space of the L-shaped pull rod 301 on the upper side inside the connecting rod cylinder 206 will be relatively smaller. Because the L-shaped pull rod 301 is fixed in the snap-fit ​​interface 101, the length of the L-shaped pull rod 301 is fixed during this process. However, when the rotating frame 203 is not pressed, the L-shaped pull rod 301... The overall length of 01 and the connecting rod cylinder 206 will be relatively short under the elastic force of the first spring 306. When the rotating frame 203 is pulled and rotated, the connecting rod cylinder 206 will rotate around the fixed frame 202. Due to the rotation, the connecting rod cylinder 206 will become relatively vertical. Therefore, the length of the connecting rod cylinder 206 in the relatively tilted state needs to be increased to accommodate the vertical state of the connecting rod cylinder 206. When the rotating frame 203 rotates and puts the connecting rod cylinder 206 vertical, the L-shaped tie rod 301 will move out of the connecting rod cylinder 206. This will compress the first spring 306, thereby ensuring that a tension is generated at the position of the L-shaped tie rod 301, which can offset some of the force caused by vibration or external force. The separation trend ensures the stability of the device. During the rotation of the rotating frame 203, the L-shaped tie rod 301 will move relative to it. When it is not rotating and is far from the rotating frame 203, the L-shaped tie rod 301 will be spread open under the force of the first spring 306. This means that the crossbar 302 will not be tightly attached to the guide groove 303. Under the tension of the damping spring 308, the distance between the disc block 307 and the crossbar 302 is relatively small. At this time, the damping spring 308 will not be subjected to too much tension, and the force of the second spring 504 will also be relatively small. The structure is in a balanced state. When the rotating frame 203 rotates, the L-shaped tie rod 301 is stretched. The crossbar 302 will fit tightly against the guide groove 303. At this time, the distance between the crossbar 302 and the disc block 307 will be relatively larger. This will stretch the damping spring 308 and generate tension. Due to the two damping springs 308, when subjected to tension, they can generate a compressive force on the first connecting square bar 309. Then, under the compression transmission of the first inclined block 310 and the second inclined block 503, the second connecting square bar 502 will push the connecting inclined block 506 to compress the pushing groove block 507. In this way, the support plate 508 will tend to open under the pushing action of the pushing groove block 507, thus ensuring the L-shaped tie rod 301 is firmly fixed, which can better ensure the stability of the column mold 1.

[0041] Furthermore, during the rotation of the rotating frame 203, the arc-shaped rod 403 is squeezed, causing a certain displacement of the arc-shaped rod 403. This displacement of the arc-shaped rod 403 drives the extrusion rod 402 to move as well. The displacement of the extrusion rod 402 is just enough to better squeeze and fix the column mold 1 inside the snap-fit ​​201, thereby better ensuring the connection effect of the snap-fit ​​201 to the column mold 1. The gap between the snap-fit ​​201 and the column mold 1 may cause wobbling, but this is avoided by the extrusion of the extrusion rod 402, ensuring the normal use of the device. When it is necessary to remove the snap-fit ​​201, simply rotate the rotating frame 203 in the opposite direction. This will cause the above structure to run in the opposite direction, thereby ensuring the removal effect of the L-shaped tie rod 301. The device highlights the innovative structure and will not elaborate too much on existing mature technologies.

[0042] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
