Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more particularly to a clamping device for a concrete baffle used in construction. Background Art

[0002] Concrete retaining panels are basic structures or components in housing construction and various engineering structures. They are often used as roofs, floors, platforms, walls, retaining walls, foundations, floors, pavements, pools, etc. They have a wide range of applications. Concrete slabs are divided into square slabs, round slabs and special-shaped slabs according to their plane shapes. They are divided into one-way slabs and two-way slabs according to the force acting on the structure. The most common ones are one-way slabs, four-side supported two-way slabs and beamless slabs supported by columns. The thickness of the slab should meet the requirements of strength and stiffness. At present, in the process of pouring concrete columns, concrete retaining panels are generally used to make a model with the retaining panels, and then concrete is poured into the model. In order to make the model stable, the retaining panels are generally fixed by a clamping device. However, the clamping device currently set can only be used to clamp and fix the same model.

DETAILED DESCRIPTION

[0028] Example 1:

[0029] At present, during the pouring of concrete columns, the concrete baffle 1 is generally used to make a model with the baffle, and then concrete is poured into the model. In order to stabilize the model, the baffle is generally fixed by a clamping device. However, the clamping device currently provided can only perform a clamping and fixing operation on the same model. Therefore, when the baffle is made into a different model, the clamping device cannot be used to clamp and fix the model. In this way, another clamping device for this model is required to perform a clamping and fixing operation, which increases the capital investment in construction to a certain extent.

[0031] The mode conversion component 2 includes an L-shaped connecting block 201, a first telescopic component 202, a second telescopic component 203, a circular rotating block 204 and a cylindrical connecting block 219. The first telescopic component 202 is provided at one end of the L-shaped connecting block 201, a circular rotating block 204 is provided on one side of the first telescopic component 202, and the second telescopic component 203 is provided at the other end of the L-shaped connecting block 201. The cylindrical connecting block 219 is provided at the upper end of the L-shaped connecting block 201.

[0032] See also Figure 3-4 As a further solution of the present invention: the first telescopic component 202 includes a shell 205, a return spring 206, a telescopic block 211, a pull rope 209, a second rotating block 210 and a clamping component 212, a return spring 206 is provided inside the shell 205, one side of the return spring 206 is fixedly connected to a rectangular connecting block 207, one side of the rectangular connecting block 207 is provided with a first rotating block 208, a pull rope 209 is sleeved on the outer surface of the first rotating block 208, the other end of the pull rope 209 is sleeved on the outer surface of the second rotating block 210, a telescopic block 211 is provided at the lower end of the second rotating block 210, a clamping component 212 is provided at the lower end of the shell 205, and a rectangular groove 213 is provided at the lower end of the shell 205. The components of the second telescopic component 203 are the same as those of the first telescopic component 202.

[0033] See also Figure 5As a further solution of the present invention: the clamping assembly 212 includes a clamping connection block 214, a clamping block 215, a circular connection block 216, a second return spring A217 and a threaded rod 218. A plurality of clamping blocks 215 are provided on the upper end surface of the clamping connection block 214, and a circular connection block 216 is provided at the lower end of the clamping block 215. The second return spring A217 is sleeved on the outer surface of the circular connection block 216, and the lower end of the second return spring A217 is provided with a threaded rod 218.

[0034] As a further solution of the present invention: the clamping connection block 214 is matched with the rectangular groove 213, the threaded rod 218 is connected to the outer surface of the clamping connection block 214 by passing through the shell 205, the upper end of the second return spring A217 is fixedly connected to the lower end surface of the clamping block 215, and a slide groove is provided inside the clamping connection block 214, and the slide groove is matched with the clamping block 215.

[0035] The steps of using the present invention are as follows: first, the concrete baffle 1 is made into a rectangular model, and then the mode conversion component 2 is placed at the two diagonal corners of the rectangular model, and the L-shaped connecting block 201 in the mode conversion component 2 is aligned with the corner of the rectangular model. At this time, the second telescopic component 203 is rotated so as to rotate around the circular rotating block 204 until one end of the second telescopic component 203 contacts the outer surface of the concrete baffle 1. At this time, the second rotating block 210 is rotated. As the second rotating block 210 rotates, the pull rope 209 is contracted, thereby generating a force on the first rotating block 208. A pulling force causes the first rotating block 208 to move forward, and the forward movement of the first rotating block 208 drives the rectangular connecting block 207 to move forward, thereby driving the return spring 206 to stretch forward and the telescopic block 211 to move forward. When the rectangular connecting block 207 contacts the clamping block 215 during the forward movement, it generates pressure on the clamping block 215, thereby causing the clamping block 215 to move downward along the sliding groove provided inside the clamping connecting block 214. When the rectangular connecting block 207 moves to the front end of the clamping block 215, the second return spring A21 7 is extended, thereby allowing the clamping block 215 to return to its original position. At this time, the clamping block 215 fixes the rectangular connecting block 207 to prevent the rectangular connecting block 207 from moving backward. When the second telescopic assembly 203 is operated, the first telescopic assembly 202 is also operated and performs the same operation as the second telescopic assembly 203. When the first telescopic assembly 202 connected to one end of the telescopic block 211 contacts the second telescopic assembly 203 provided at one end of another mode conversion assembly 2, the second rotating block 210 stops rotating, and the concrete baffle 1 is fixed at this time. Then, concrete is poured into the rectangular mold until it solidifies and forms. Then, the threaded rod 218 in the first telescopic assembly 202 and the threaded rod 218 in the second telescopic assembly 203 are rotated until the clamping connecting block 214 fits into the rectangular groove 213. At this time, the return spring 206 is contracted. Through the mode conversion assembly 2, the one-way plate and the four-side supported two-way plate can be clamped and fixed, which increases the diversity of the model of the clamping device fixing the concrete baffle 1 and reduces the investment cost of construction to a certain extent.

[0036] Example 2:

[0037] The use of concrete baffle 1 During the pouring of concrete columns, a model is generally made of a baffle, and then concrete is poured into the model. In order to stabilize the model, the baffle is generally fixed by screws, wires or clips. Although it can be used stably, the connection of the baffle is too time-consuming and labor-intensive, and it is inconvenient to remove it after the concrete is formed, which delays the work progress.

[0038] See also Figure 8-9As a further solution of the present invention: the first connecting component 3 includes a first rectangular connecting block 301, a second return spring B303 and a rack 304, the first rectangular connecting block 301 is provided with a groove 302 inside, the second return spring B303 is provided on the inner side of the first rectangular connecting block 301, the upper end of the second return spring B303 is provided with a rack 304, a sliding block 305 is provided on one side of the rack 304, and a slider 306 is provided at one end of the rack 304.

[0039] See also Figure 7 As a further solution of the present invention: the second connecting component 4 includes a third rectangular connecting block 401, a fixed block 402, a gear 403 and a rotating block 404. The fixed block 402 is provided on one side of the third rectangular connecting block 401, and the rotating block 404 is provided at one end of the fixed block 402. The fixed block 402 is movably connected to the rotating block 404 through the gear 403, and a rectangular rotating block 405 is provided at the upper end of the third rectangular connecting block 401.

[0040] See also Figure 6-8 As a further solution of the present invention: the fixed block 402 and the rotating block 404 fit into the groove 302, the first connecting component 3 is fixed on the outer surface of one end of the first telescopic component 202, and the second connecting component 4 is fixed on the outer surface of one end of the second telescopic component 203.

[0041] The use steps of the present invention are as follows: first, the concrete baffle 1 is made into a one-way plate model, and the second telescopic component 203 and the first telescopic component 202 are placed at the same horizontal plane, and then one end of the second telescopic component 203 and the first telescopic component 202 are attached to the outer surface of one end of the concrete baffle 1. At this time, the second telescopic component 203 and the first telescopic component 202 are extended until the second connecting component 4 provided at one end of the mode conversion component 2 contacts the first connecting component 3 provided at one end of the other mode conversion component 2. At this time, the rotating block 404 in the second connecting component 4 is in the groove 302 provided inside the first connecting component 3, and when the rotating block 404 moves in the groove 302, it drives the slider 306 to move into the groove 302. When the rotating block 404 contacts the bottom of the groove, the rotating block 4 04 cannot generate pressure on the rack 304, thereby allowing the second return spring B303 to stretch, thereby driving the rack 304 to move upward, and the upward movement of the rack 304 will drive the gear 403 to rotate, thereby causing the rotating block 404 to rotate counterclockwise until the rotating block 404 and the fixed block 402 are at ninety degrees. At this time, the first connecting component 3 and the second connecting component 4 are clamped together, thereby clamping and fixing the concrete baffle 1. When the concrete is solidified, the sliding block 305 is moved along the slide groove provided on the surface of the first rectangular connecting block 301 until the first connecting component 3 and the second connecting component 4 are separated. In this way, the fixation of the concrete baffle 1 can be released, thereby facilitating dismantling after the concrete is formed, speeding up the project progress to a certain extent, and saving time and effort.

[0042] Example 3:

[0043] In the one-way slab model formed by the concrete baffles 1 , since the stability between the concrete baffles 1 is poor, misalignment is easily generated, which is not conducive to the use of the concrete baffles 1 .

[0044] See also Figure 10 As a further solution of the present invention: the horizontal component 5 includes a first rectangular telescopic rod 501, a second rectangular telescopic rod 503, a spirit level 502, a second circular connecting block 504 and a third circular connecting block 505, the spirit level 502 is provided on the upper end surface of the first rectangular telescopic rod 501, and the second rectangular telescopic rod 503 is provided at one end of the first rectangular telescopic rod 501, the second circular connecting block 504 is provided at one end of the second rectangular telescopic rod 503, and the third circular connecting block 505 is provided at one end of the first rectangular telescopic rod 501, a circular hole is provided in the middle part of the second circular connecting block 504, and the circular hole provided in the middle part of the second circular connecting block 504 fits with the cylindrical connecting block 219.

[0045] The steps of using the present invention are as follows: by aligning the first circular connecting block 504 with the cylindrical connecting block 219, and then pulling the second rectangular telescopic rod 503, the length of the first rectangular telescopic rod 501 and the second rectangular telescopic rod 503 are equal to the distance between the two cylindrical connecting blocks 219, and then the first circular connecting block 504 and the second circular connecting block 505 are sleeved on the outer surface of the cylindrical connecting block 219, and then the level meter 502 is used to observe whether the first rectangular telescopic rod 501 and the second rectangular telescopic rod 503 are in the same horizontal plane. If they are in the same horizontal plane, the concrete baffle 1 is in the same horizontal plane, and the concrete baffle 1 will not be misplaced. At the same time, the stability between the concrete baffles 1 is increased on a certain basis, and the quality of the construction process is also guaranteed.

[0046] Working principle: First, the concrete baffle 1 is made into a rectangular model, and then the mode conversion component 2 is placed at the two diagonal corners of the rectangular model, and the L-shaped connecting block 201 in the mode conversion component 2 is fitted with the corners of the rectangular model. At this time, the second telescopic component 203 is rotated so as to rotate around the circular rotating block 204 until one end of the second telescopic component 203 contacts the outer surface of the concrete baffle 1. At this time, the second rotating block 210 is rotated. As the second rotating block 210 rotates, the pull rope 209 will be contracted, thereby generating a pulling force on the first rotating block 208, thereby allowing the first rotating block 208 to move forward, and the forward movement of the first rotating block 208 will drive the rectangular connecting block 207 to move forward, thereby driving the return spring 206 to extend forward. As the telescopic block 211 moves forward, when the rectangular connecting block 207 contacts the clamping block 215 during the process of moving forward, pressure is generated on the clamping block 215, thereby allowing the clamping block 215 to move downward along the sliding groove provided inside the clamping connecting block 214. When the rectangular connecting block 207 moves to the front end of the clamping block 215, the second return spring A217 stretches, thereby allowing the clamping block 215 to return to its original position. At this time, the clamping block 215 fixes the rectangular connecting block 207 to prevent the rectangular connecting block 207 from retreating. While the second telescopic assembly 203 is operating, the first telescopic assembly 202 is also operated, and performs the same operation as the second telescopic assembly 203, and the first telescopic assembly 202 connected to one end of the telescopic block 211 is 2 When the second telescopic assembly 203 provided at one end of the other mode conversion assembly 2 comes into contact with the second telescopic assembly 203, the second rotating block 210 stops rotating, and the concrete baffle 1 is fixed at this time. Then, concrete is poured into the rectangular model until it solidifies and forms. Then, the threaded rod 218 in the first telescopic assembly 202 and the threaded rod 218 in the second telescopic assembly 203 are rotated until the clamping connection block 214 fits into the rectangular groove 213. At this time, the return spring 206 is contracted. The mode conversion assembly 2 can be used to clamp and fix the one-way plate and the four-side supported two-way plate, which increases the diversity of the model composed of the clamping device fixing the concrete baffle 1 and reduces the investment cost of the construction on a certain basis. Then, the concrete baffle 1 is fixed. A one-way slab model is made, and the second telescopic component 203 and the first telescopic component 202 are placed at the same horizontal plane, and then one end of the second telescopic component 203 and the first telescopic component 202 are attached to the outer surface of one end of the concrete retaining plate 1. At this time, the second telescopic component 203 and the first telescopic component 202 are extended until the second connecting component 4 provided at one end of the mode conversion component 2 contacts the first connecting component 3 provided at one end of the other mode conversion component 2. At this time, the rotating block 404 in the second connecting component 4 is in the groove 302 provided inside the first connecting component 3, and when the rotating block 404 moves in the groove 302, it drives the slider 306 to move into the groove 302. When the rotating block 404 contacts the bottom of the groove,The rotating block 404 is unable to exert pressure on the rack 304, causing the second return spring B303 to stretch, thereby driving the rack 304 upward. The upward movement of the rack 304 drives the gear 403 to rotate, causing the rotating block 404 to rotate counterclockwise until the rotating block 404 and the fixed block 402 are at a 90-degree angle. At this point, the first connecting assembly 3 and the second connecting assembly 4 are clamped together, thereby clamping and fixing the concrete retaining plate 1.

[0047] When the first connecting component 3 and the second connecting component 4 are clamped together, the first circular connecting block 504 is aligned with the cylindrical connecting block 219, and then the second rectangular telescopic rod 503 is pulled to make the length of the first rectangular telescopic rod 501 and the second rectangular telescopic rod 503 equal to the distance between the two cylindrical connecting blocks 219, and then the first circular connecting block 504 and the second circular connecting block 505 are sleeved on the outer surface of the cylindrical connecting block 219, and the level 502 is used to observe whether the first rectangular telescopic rod 501 and the second rectangular telescopic rod 503 are in the same horizontal plane. If they are in the same horizontal plane, The concrete baffles 1 are on the same horizontal plane, so there will be no misalignment of the concrete baffles 1. At the same time, the stability between the concrete baffles 1 is increased to a certain extent, and the quality of the construction process is guaranteed. After the concrete is solidified and formed, the sliding block 305 is moved along the slide groove set on the surface of the first rectangular connecting block 301 until the first connecting component 3 is separated from the second connecting component 4. This can release the fixation of the concrete baffle 1, making it easier to dismantle after the concrete is formed, and to a certain extent speed up the project progress, and also save time and effort.
