Description

Technical Field

[0001] This invention relates to the field of steel frame and concrete structure connection technology, specifically a steel frame and concrete structure connection structure. Background Technology

[0002] The steel frame and concrete structure docking structure is a steel frame that is firmly installed on a cement wall. Its core function is to connect the external decorative panels with the internal wall into a whole, avoiding the risk of the decorative layer falling off and providing a flat and firm installation base for the surface.

[0003] Patent CN208950062U discloses a prefabricated steel frame concrete floor slab composite structure. The composite structure includes a prefabricated steel frame wall and a prefabricated reinforced concrete floor slab. The prefabricated wall includes a wall body and a steel frame serving as a supporting structure for the wall body. Two prefabricated walls are spliced ​​together vertically, with the lower protrusion of the upper prefabricated wall column connecting and fixedly connected to the upper protrusion of the lower prefabricated wall column. A gap is left between the lower frame beam of the upper prefabricated wall and the upper frame beam of the lower prefabricated wall, and concrete is poured into the gap, thereby connecting the upper prefabricated wall, the lower prefabricated wall, and the prefabricated floor slab into a whole. This patent simplifies the connection structure between the reinforced concrete floor slab and the main structure, avoids a large amount of steel reinforcement work on the construction site, and improves construction efficiency.

[0004] However, the following problems exist: During the connection between the steel frame and the concrete structure, the steel frame is installed in front of the concrete wall. At this time, the steel frame is suspended in front of the concrete wall. Long-term suspension will cause the steel frame to loosen and shift, resulting in poor installation effect. In addition, there is no support in the middle of the steel frame, which will cause uneven stress and deformation inside the steel frame. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a steel frame and concrete structure connection structure, which solves the problem that long-term suspension of the steel frame can lead to loosening and displacement, resulting in poor installation performance.

Four inclined plates are fixed to the outer walls of two I-shaped shafts in pairs. Two rubber rollers are respectively rotatably mounted on one side of four inclined plates that are close to each other. The inclined plates drive the rubber rollers to move backward. Under the constraint of the concrete wall, the rubber rollers roll to both sides on the surface of the concrete wall. When the steel frame is released, the torsion spring quickly returns to its original position.

[0012] According to the above technical solution, the four torsion springs are respectively sleeved on the outer walls of the two I-shaped shafts, the four inclined plates are located inside the groove of the U-shaped plate, and the outer walls of the two rubber rollers are in contact with the front of the concrete wall.

[0013] According to the above technical solution, two T-shaped columns are slidably installed through the front of the U-shaped plate. A square plate is fixed to the front of the two T-shaped columns. The front of the square plate is in contact with the back of the steel frame. Four arc-shaped spring pieces are fixed to the back of the square plate. The ends of the four arc-shaped spring pieces away from the square plate are fixedly connected to the front of the U-shaped plate. When the steel frame is released, the elastic force of the torsion spring pushes the U-shaped plate forward. The U-shaped plate slides forward on the surface of the T-shaped columns, and the U-shaped plate squeezes the arc-shaped spring pieces.

[0014] According to the above technical solution, the cover device includes: Four springs are fixed to the back of the inner wall of the two circular cavities of the two loop blocks respectively; Four cylinders, each of which is fixed to the back of one of the four springs; Two long plates are respectively embedded in the back of four cylinders; Four connecting plates are fixed to the left and right sides of the two long plates, respectively.

Under the constraint of the concrete wall, the second spring contracts and deforms. When the steel frame is released, the long plates are pressed tightly against the surface of the concrete wall under the elastic force of the second spring.

[0016] This invention provides a steel frame and concrete structure connection structure. It has the following advantages: (1) Push the steel frame to move backward, the steel frame drives the strip shell to move backward, the strip shell drives the T-shaped plate to move backward, the T-shaped plate drives the square and round frame to move backward, the square and round frame drives the hollow column to move backward, the strip shell drives the spring to move backward, the strip frame is restricted by the concrete wall, the T-shaped plate slides forward in the groove of the strip shell, the spring on the T-shaped plate contracts and stores energy, the hollow column and the arc hook plate make contact inside, improving the docking efficiency and accuracy of the steel frame and the concrete wall surface; release the steel frame, the spring releases the contracted elastic force, the arc hook plate hooks the hollow column, under the elastic force of the spring, the strip frame is firmly pressed against the concrete wall surface, the spring is pressed against the strip shell, so that the steel frame is stably suspended in front of the concrete wall, preventing the steel frame from loosening and shifting due to long-term suspension use, resulting in poor installation effect of the steel frame.

[0017] (2) Under the constraint of the concrete wall, the rubber roller rolls on both sides of the concrete wall surface. The I-shaped shaft rotates in the round hole of the U-shaped plate. The torsion spring on the I-shaped shaft rotates and deforms, releasing the steel frame. The torsion spring quickly returns to its original position. The rubber roller presses against the concrete wall surface through the elastic force of the torsion spring, improving the internal support of the steel frame and preventing uneven deformation of the steel frame due to lack of internal support. The elastic force of the torsion spring pushes the U-shaped plate forward. The U-shaped plate slides forward on the surface of the T-shaped column.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Please see Figures 1-10 One embodiment of the present invention is: a steel frame and concrete structure connection structure, comprising: Concrete wall 1 and steel frame 5. The front of concrete wall 1 is provided with two protruding strips 2. A strip plate 3 is fixed to the front of each of the two protruding strips 2. Two arc hook plates 4 are fixed to the front of each of the two strip plates 3. Two strip shells 10 are fixed to the left and right sides of the steel frame 5, and a sliding groove is opened on the back of each of the two strip shells 10. Four square and round frames 11 are fixed in pairs on the side of the two strip shells 10 that are close to each other. Four hollow columns 12 are fixed to the inner walls of four square and round frames 11 respectively, and the outer walls of the four hollow columns 12 slide in contact with the inner walls of the four arc hook plates 4. Several springs 13 are fixed to the back of the inner walls of the two shells 10 respectively; Two T-shaped plates 14 are slidably installed on the inner wall of the groove of the two strip shells 10 respectively, and the back of each spring-13 is fixedly connected to the front of the two T-shaped plates 14. Two frames 15 are fixed to the outer walls of two T-shaped plates 14 respectively, and the back of the two frames 15 are in contact with the front of the concrete wall 1.

[0023] Several L-shaped plates 6 are fixedly installed on the inner wall of the steel frame 5. A hanging piece 7 is fixedly installed on the front of each L-shaped plate 6. A herringbone block 8 is fixed on the top and bottom surfaces of the steel frame 5. A foam layer 9 is fixed on the inner wall of each of the two herringbone blocks 8. The steel frame 5 has several notches on its front side. Two L-shaped plates 6 are fixed to the top of the inside of the steel frame 5. Each L-shaped plate 6 is fixed inside each notch of the steel frame 5. A T-shaped groove is provided on the lower front side of each L-shaped plate 6. The outer wall of each hanger 7 is fixedly connected to the inner wall of the T-shaped groove of each L-shaped plate 6. A disc is provided at one end of each of the four hollow columns 12 that are close to each other. The discs of the four hollow columns 12 are used to limit the position of the steel frame 5 on the front of the concrete wall 1. Two circular cavities are provided on the back of the two U-shaped blocks 8. The steel frame 5 is located in front of the convex strip block 2. Each hanger 7 is located in front of the steel frame 5. The four hollow columns 12 are located behind the steel frame 5. A pressure-dividing device 16 is provided on one side of each of the two T-shaped plates 14 that are close to each other. The pressure-dividing device 16 is used to push the steel frame 5 back. The operator uses expansion bolts to install the strip 3 in front of the convex strip 2, installs the L-shaped plate 6 inside the steel frame 5, and then installs the hanger 7 inside the T-shaped groove of each L-shaped plate 6. The steel frame 5 is lifted by the crane cable. The steel frame 5 drives the L-shaped plate 6 to move upward, the L-shaped plate 6 drives the hanger 7 to move upward, the steel frame 5 drives the loop block 8 to move upward, the loop block 8 drives the foam layer 9 to move upward, the steel frame 5 drives the strip shell 10 to move upward, the strip shell 10 drives the T-shaped plate 14 to move upward, the T-shaped plate 14 drives the square and round frame 11 to move upward, the square and round frame 11 drives the hollow column 12 to move upward, and the hollow column 12 moves to the top of the arc hook plate 4. The operator pushes the steel frame 5 backward, which in turn moves the U-shaped block 8 backward, which in turn moves the foam layer 9 backward, the steel frame 5 moves the strip shell 10 backward, the strip shell 10 moves the T-shaped plate 14 backward, the T-shaped plate 14 moves the square and round frame 11 backward, the square and round frame 11 moves the hollow column 12 backward, and at the same time, the strip shell 10 moves the spring 13 backward. The frame 15 on the T-shaped plate 14 is restricted by the concrete wall 1, and the T-shaped plate 14 slides forward in the groove of the strip shell 10. The spring 13 on the T-shaped plate 14 contracts to store energy. The crane's cable lowers the steel frame 5, which in turn moves the strip shell 10 downwards. The strip shell 10 then moves the T-shaped plate 14 downwards, which in turn moves the square-round frame 11 downwards. The square-round frame 11 then moves the hollow column 12 downwards. The hollow column 12 contacts the inside of the arc hook plate 4, improving the efficiency and accuracy of the connection between the steel frame 5 and the surface of the concrete wall 1. The operator releases the steel frame 5, and the spring 13 releases its contraction force. At this time, the strip shell 10 slides forward on the surface of the T-shaped plate 14, which in turn moves the steel frame 5 forward. The arc hook plate 4 hooks the hollow column 12, and the steel frame 5 is suspended in front of the concrete wall 1. Under the elastic force of the spring 13, the strip frame 15 is firmly pressed against the surface of the concrete wall 1, and the spring 13 is pressed against the strip shell 10, so that the steel frame 5 is stably suspended in front of the concrete wall 1. This avoids the problem that the steel frame will loosen and shift due to prolonged suspension during the connection process with the concrete structure, resulting in poor installation effect.

[0024] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, the circular opening of the loop block 8 is provided with a cover device 17, which is used to enclose the upper and lower parts of the steel frame 5.

[0025] The pressure divider device 16 includes: A U-shaped plate 161 is fixed to the middle of two T-shaped plates 14 that are close to each other on one side. The U-shaped plate 161 has a slot on its front side and round holes on its top and bottom surfaces. Two I-shaped shafts 162 are rotatably mounted on the inner wall of the circular hole of the spiral plate 161. Four torsion springs 163 are fixed in pairs to the top and bottom of the spiral plate 161. The ends of the four torsion springs 163 away from the spiral plate 161 are fixedly connected to the outer walls of the two I-shaped shafts 162. Four inclined plates 164 are fixed to the outer wall of two I-shaped shafts 162 in pairs. Two rubber rollers 165 are respectively rotatably installed on one side of the four inclined plates 164 that are close to each other; As the shell 10 moves the T-shaped plate 14 backward, the T-shaped plate 14 moves the U-shaped plate 161 backward, the U-shaped plate 161 moves the I-shaped shaft 162 backward, the I-shaped shaft 162 moves the torsion spring 163 backward, the I-shaped shaft 162 moves the inclined plate 164 backward, and the inclined plate 164 moves the rubber roller 165 backward. Under the constraint of the concrete wall 1, the rubber roller 165 rolls to both sides on the surface of the concrete wall 1. Simultaneously, the inclined plate 164 drives the I-shaped shaft 162 to rotate. The I-shaped shaft 162 rotates within the circular hole of the U-shaped plate 161. The torsion spring 163 on 162 rotates and deforms. When the operator releases the steel frame 5, the torsion spring 163 quickly returns to its original position, and the rubber roller 165 rolls towards the center on the surface of the concrete wall 1. Under the elastic force of the torsion spring 163, the hollow column 12 quickly slides into the arc hook plate 4, completing the connection between the arc hook plate 4 and the hollow column 12. At the same time, the rubber roller 165 presses against the surface of the concrete wall 1 through the elastic force of the torsion spring 163, improving the internal intermediate support of the steel frame 5. This avoids the problem of uneven deformation caused by the lack of internal support in the steel frame during the docking process with the concrete structure.

[0026] Four torsion springs 163 are respectively fitted on the outer walls of two I-shaped shafts 162, four inclined plates 164 are located inside the groove of the U-shaped plate 161, and the outer walls of two rubber rollers 165 are in contact with the front of the concrete wall 1; two T-shaped columns 166 are slidably installed through the front of the U-shaped plate 161, and square plates 167 are fixed on the front of the two T-shaped columns 166. The front of the square plates 167 is in contact with the middle of the back of the steel frame 5, and four arc-shaped spring pieces 168 are fixed on the back of the square plates 167. The ends of the four arc-shaped spring pieces 168 away from the square plates 167 are fixedly connected to the front of the U-shaped plate 161. As the U-shaped plate 161 moves backward along with the I-shaped shaft 162, the U-shaped plate 161 moves the T-shaped column 166 backward, the T-shaped column 166 moves the square plate 167 backward, and the square plate 167 moves the arc-shaped spring piece 168 backward. When the operator releases the steel frame 5, the elastic force of the torsion spring 163 pushes the U-shaped plate 161 forward. The U-shaped plate 161 slides forward on the surface of the T-shaped column 166, and the U-shaped plate 161 squeezes the arc-shaped spring piece 168. The arc-shaped spring piece 168 deforms and bends, so that the U-shaped plate 161 presses tightly against the back of the steel frame 5, thereby avoiding the problem of poor suspension effect of the steel frame 5 caused by the loosening of the middle of the back of the steel frame 5 during the connection between the steel frame and the concrete structure.

[0027] Cover device 17 includes: Four springs 2171 are fixed to the back of the inner wall of the two circular cavities of the two loop blocks 8 respectively; Four cylinders 172 are fixed to the back of four springs 171 respectively; Two long plates 173 are respectively embedded in the back of four cylinders 172; Four connecting plates 174 are fixed to the left and right sides of the two long plates 173 respectively; the outer walls of the four cylinders 172 slide in contact with the inner walls of the cavities of the two loop blocks 8; the two long plates 173 are located behind the two loop blocks 8 respectively; and the four connecting plates 174 are located above and below the two T-shaped plates 14 respectively. As the U-shaped block 8 moves the foam layer 9 backward, the U-shaped block 8 moves the second spring 171 backward, the second spring 171 moves the cylinder 172 backward, the cylinder 172 moves the long plate 173 backward, the long plate 173 moves the connecting plate 174 backward, and the connecting plate 174 moves backward synchronously with the T-shaped plate 14. Under the constraint of the concrete wall 1, the second spring 171 contracts and deforms. When the operator releases the steel frame 5, under the elastic force of the second spring 171, the long plate 173 presses tightly against the surface of the concrete wall 1, so that the upper and lower parts of the steel frame 5 are sealed by the long plate 173, thereby avoiding a large gap between the steel frame 5 and the concrete wall 1 during the connection process between the steel frame and the concrete structure, which would cause a large amount of external rainwater to enter the interior of the steel frame 5.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
