Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a concrete pouring separator. Background Technology

[0002] In construction engineering, concrete pouring is one of the key construction steps. With the increasing complexity of building structures and the diversification of functional requirements, different grades or properties of concrete may need to be poured in the same building structure. For example, shear walls and floor slabs of high-rise buildings may use concrete of different strengths to ensure the overall performance and durability of the structure. In traditional construction, temporary formwork or manual mortar stacking is usually used for separation. However, these methods have problems such as low efficiency, poor accuracy, and easy leakage of mortar. In recent years, some simple separation devices have appeared on the market, but they still cannot fully meet the construction needs, especially in the application of rapid construction and large-scale projects.

[0003] Currently, common concrete partitioning techniques mainly include the following: First, using temporary wooden or steel formwork to achieve partitioning through fixed supports, but the formwork installation is time-consuming and seams are easily left after removal; second, using flexible partition strips made of plastic or rubber, which are easy to install but lack rigidity and are prone to deformation under concrete pressure; third, using precast concrete blocks as partitions, but they are heavy, difficult to transport, and cannot flexibly adjust the partition position. Each of these methods has its advantages and disadvantages. Wooden formwork is low in cost but easily damaged, steel formwork is durable but heavy, and flexible partition strips are lightweight but have poor stability.

[0004] The main drawbacks of existing technologies are that the stability, flexibility, and construction efficiency of the separation device cannot be balanced. Wooden and steel templates are complicated to install and take a long time. Flexible separators are prone to displacement or deformation during concrete pouring, resulting in inaccurate separation. Precast concrete blocks lack flexibility and are difficult to adapt to complex and ever-changing construction needs. In addition, existing technologies also have problems such as grout leakage and difficulty in joint treatment, which affect the overall quality and aesthetics of the concrete structure. Therefore, we propose a concrete pouring separator. Summary of the Invention

[0005] The purpose of this invention is to provide a concrete pouring separator to solve the existing problems mentioned in the background art.

[0006] In a first aspect, the concrete pouring separator provided in this application adopts the following technical solution: A concrete pouring separator includes a main frame, the main frame including an upper crossbeam, a lower crossbeam and columns, the two opposite sides of the two columns are fixedly connected to the two ends of the upper and lower crossbeams, the upper crossbeam is located above the lower crossbeam and includes an adjustment assembly, the adjustment assembly including a movable plate, a connector fixedly connected to one side of the movable plate, an adjustment screw movably connected to the top of the connector via a bearing, one end of the adjustment screw movably connected through the upper crossbeam, a nut threadedly connected to a section of the adjustment screw extending out of the upper crossbeam, the nut being located above the upper crossbeam, a sliding sleeve fixedly connected to one side of the movable plate, a sliding rod slidably sleeved on the inner wall of the sliding sleeve, one end of the sliding rod fixedly connected to the top of the lower crossbeam, a fixed plate fixedly connected to the top of the lower crossbeam, and the opposite side of the fixed plate being fixedly connected to the opposite side of the two columns.

[0007] Preferably, the length of the adjusting screw is adjusted by limiting the upper crossbeam, and the movable plate and the fixed plate are staggered and fit together.

[0008] Preferably, the slide bar limits the movable plate through the sliding sleeve, and the slide bar and sliding sleeve are also used to provide support for the movable plate and resist the pressure of the movable plate's casting surface.

[0009] Preferably, the movable plate is adjusted by rotating the nut to move the adjusting screw vertically to adapt to the pouring height.

[0010] Secondly, the concrete pouring separator provided in this application adopts the following technical solution: it includes a fastening assembly, the fastening assembly includes a bracket, one end of the bracket is fixedly connected to one side of a movable plate, a bidirectional screw is movably sleeved inside the bracket through a bearing, a sheath is fixedly sleeved on the middle of the side surface of the bidirectional screw, internal thread sleeves are threaded to both ends of the bidirectional screw, a backing plate is fixedly connected to the other end of the internal thread sleeve, a movable sleeve is fixedly connected to the opposite side of the two backing plates, a movable rod is fixedly connected to the opposite side of the two brackets and the movable rod is movably sleeved in the movable sleeve, a groove is opened on the edge of the opposite side of the two backing plates, and a sealing strip is fixedly connected in the groove. The backing plate, the groove and the sealing strip together constitute a sealing assembly.

[0011] Preferably, the main frame is disposed in a pouring trough for pouring concrete, and the two abutment plates abut against the inner wall of the opposite side of the pouring trough.

[0012] Preferably, the bidirectional screw is used to adjust the relative position of the abutment plate and the inner wall of the casting trough by rotating the sheath, and one side of the sealing strip is used to abut against the inner wall of the casting trough, and the side of the sealing strip near the column abuts against the column through elastic deformation.

[0013] Preferably, the two opposing sides of the abutment plates abut against the inner wall of the opposite side of the casting trough to fix the main frame and resist the pressure of the casting surface.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. The divider is precisely placed in the pouring trough, ensuring the column is in the correct position. At the same time, the side of the movable plate away from the support faces the pouring direction to prepare for the subsequent pouring operation. Next, the height of the movable plate is adjusted by turning the nut, which drives the adjusting screw to move up and down. Since the adjusting screw is connected to the movable plate, its movement will cause the movable plate to rise and fall accordingly until it is adjusted to the required pouring height to meet the height requirements of different pouring scenarios.

[0016] 2. By rotating the bidirectional screw, the abutment plate is pressed tightly against the inner wall of the pouring trough, which not only enhances the sealing effect but also fixes the main frame to resist the pressure of the pouring surface, thereby improving stability. At the same time, when removing it, by reversing the bidirectional screw, the abutment plate is detached from the inner wall of the pouring trough, thereby releasing the fixed state of the main frame. This allows the separator to be easily separated from the pouring surface, thereby improving construction efficiency and operability. In addition, the pouring surfaces of the movable plate and the fixed plate are flat, which improves the aesthetics after pouring. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0023] Example 1: This embodiment of the present invention provides a concrete pouring separator, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the system includes a main frame 1, which comprises an upper crossbeam 101, a lower crossbeam 102, and columns 103. The two columns 103 are fixedly connected to the two ends of the upper and lower crossbeams 101 and 102 on opposite sides. The upper crossbeam 101 is located above the lower crossbeam 102. The adjustment assembly 2 includes a movable plate 201, with a connector 202 fixedly connected to one side. An adjusting screw 204 is movably connected to the top of the connector 202 via a bearing. The movable plate 201 is rotated via a nut 203 to adjust the adjusting screw 204. 4. Vertical movement is used to adapt to the pouring height. One end of the adjusting screw 204 passes through the upper crossbeam 101 and is movably connected. A nut 203 is threaded onto a section of the adjusting screw 204 that extends out of the upper crossbeam 101. The nut 203 is located above the upper crossbeam 101. The adjusting screw 204 and the nut 203 are made of 304 stainless steel, which is corrosion-resistant and has high strength. A sliding sleeve 205 is fixedly connected to one side of the movable plate 201. A sliding rod 206 is slidably fitted onto the inner wall of the sliding sleeve 205. One end of the sliding rod 206 is fixedly connected to the lower crossbeam 102. At the top, the sliding rod 206 limits the movable plate 201 via the sliding sleeve 205. The sliding rod 206 and the sliding sleeve 205 also provide support for the movable plate 201 and resist the pressure of the cast surface of the movable plate 201. The top of the lower crossbeam 102 is fixedly connected to the fixed plate 207, and the opposite side of the fixed plate 207 is fixedly connected to the opposite side of the two columns 103. The nut 203 limits the length of the adjusting screw 204 via the upper crossbeam 101. The movable plate 201 and the fixed plate 207 are staggered and the movable plate 201 and the fixed plate 207 are also staggered. The components 207 are fitted together. By adjusting the adjusting screw 204, nut 203 and movable plate 201 in component 2, the movable plate 201 can be rotated through the nut 203. By rotating the nut 203, the adjusting screw 204 is driven to move up and down. Since the adjusting screw 204 is connected to the movable plate 201, its movement will cause the movable plate 201 to rise and fall accordingly until it is adjusted to the required pouring height to meet the height requirements of different pouring scenarios. The height can be adjusted to adapt to the pouring of concrete of different thicknesses, thereby improving the flexibility of use.

[0024] The implementation principle of this application embodiment is as follows: The divider is accurately placed in the pouring trough 5, and it is necessary to ensure that the column 103 is in the correct position. At the same time, the side of the movable plate 201 away from the bracket 301 faces the pouring direction to prepare for the subsequent pouring operation. Then, the height of the movable plate 201 is adjusted by rotating the nut 203, which drives the adjusting screw 204 to move up and down. Since the adjusting screw 204 is connected to the movable plate 201, its movement will cause the movable plate 201 to rise and fall accordingly until it is adjusted to the required pouring height to meet the height requirements of different pouring scenarios.

[0025] Example 2: This embodiment of the present invention provides a concrete pouring separator, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fastening assembly 3 includes a bracket 301. One end of the bracket 301 is fixedly connected to one side of the movable plate 201. A bidirectional screw 304 is movably sleeved inside the bracket 301 via a bearing. A sheath 303 is fixedly sleeved on the middle of the side surface of the bidirectional screw 304. Both ends of the bidirectional screw 304 are threadedly connected to internal threaded sleeves 305. The other end of the internal threaded sleeves 305 is fixedly connected to abutment plates 401. The opposite sides of the two abutment plates 401 abut against the inner wall of the opposite side of the casting trough 5 to fix the main frame 1 and resist the pressure of the casting surface. A movable sleeve 306 is fixedly connected to the opposite side of the two abutment plates 401. Movable rods 302 are fixedly connected to the opposite sides of the two brackets 301, and the movable rods 302 are movably sleeved in the movable sleeves 306. A recess is formed on the edge of the opposite side of the two abutment plates 401. A sealing strip 403 is fixedly connected inside the groove 402. The abutment plate 401, the groove 402, and the sealing strip 403 together constitute the sealing component 4. The main frame 1 is set inside the pouring trough 5 for pouring concrete. The opposite sides of the two abutment plates 401 abut against the inner wall of the opposite side of the pouring trough 5. The bidirectional screw 304 is rotated by rotating the sleeve 303. The two ends of the bidirectional screw 304 are threadedly connected to the internal thread sleeve 305. The other end of the internal thread sleeve 305 is fixedly connected to the abutment plate 401. The opposite sides of the two abutment plates 401 abut against the inner wall of the opposite side of the pouring trough 5 to fix the main frame 1 and resist the pressure of the pouring surface. The main frame 1 is made of 6061 aluminum alloy profile, which has the characteristics of being lightweight and high-strength. The sealing strip 403 is made of oil-resistant and aging-resistant nitrile rubber to ensure that it does not deform during long-term use.

[0026] The implementation principle of this application embodiment is as follows: During installation, the bidirectional screw 304 is rotated by rotating the protective sleeve 303. The two ends of the bidirectional screw 304 are threadedly connected to the internal thread sleeve 305. The other end of the internal thread sleeve 305 is fixedly connected to the abutment plate 401. The opposite sides of the two abutment plates 401 abut against the inner wall of the opposite side of the pouring tank 5 to fix the main frame 1 and resist the pressure of the pouring surface, thereby causing the two abutment plates 401 to move in opposite directions until the abutment plates 401 abut against the inner wall of the pouring tank 5 to complete the fixation. At the same time as the abutment plates 401 abut against the inside of the pouring tank 5, the sealing strip 403 seals the two sides of the column 103 to prevent leakage during pouring. When removing, the bidirectional screw 304 is reversed to make the abutment plates 401 detach from the inner wall of the pouring tank 5, thereby releasing the fixed state of the main frame 1, so that the separator can be easily separated from the pouring surface, thereby improving construction efficiency, improving operability, and making the pouring surface flat, thus improving the aesthetics after pouring.
