[0023] Embodiment 1

[0024] As Figures 1-6As shown in the figure, a beam formwork support device for building construction includes a housing 1 and a hydraulic rod 101. A number of hydraulic rods 101 are installed at the top of the housing 1. There are four hydraulic rods 101. It also includes a cross plate 102. The output ends of the four hydraulic rods 101 are fixedly connected to the same cross plate 102. An extension mechanism is provided on the cross plate 102.

An inclined groove is opened in the first sliding groove of the circular ring 203.

[0025] The extension mechanism also includes a sliding rod 204. The first sliding groove is used to provide movement for the sliding rod 204. The sliding rod 204 is symmetrically slidably connected to the inclined groove of the circular ring 203. One end of the two sliding rods 204 is fixedly connected to a second support plate 302. The inclined groove can enable the sliding rod 204 to drive the second support plate 302 to lift. The second support plate 302 is oval. The bottom end of the second support plate 302 is fixedly connected to the two fixed columns 202. Connecting rods 205 are symmetrically hinged to the bottom end of the long plate 201. One end of the connecting rod 205 is connected to a support block 206. A sliding groove 207 is fixedly connected to the bottom of one of the support blocks 206. The bottom of the sliding groove 207 is slidably connected to the top of the cross plate 102.

[0026] The extension mechanism also includes a moving block 208. The moving block 208 is slidably connected to the sliding groove 207. The moving block 208 is fixedly connected to one of the support blocks 206. First support plates 301 are fixedly connected to both support blocks 206. Triangular support plates 3 are fixedly connected to both sides of the cross plate 102. Both triangular support plates 3 can support the two first support plates 301. The first support plate 301 contacts the triangular support plate 3 when it moves.

[0027] It also includes a locking plate 4. The locking plate 4 is fixedly connected to the top of the housing 1. A square groove is opened on the locking plate 4. A locking block 401 is slidably connected to the square groove of the locking plate 4. One side of the locking block 401 is an inclined surface and the other side is a flat surface. A first elastic member is connected between the locking block 401 and the square groove of the locking plate 4. The first elastic member is a spring. A rectangular square groove is opened on one side of the locking plate 4. The rectangular square groove of the locking plate 4 is communicated with the square groove. A pressing plate 402 is slidably connected to the rectangular square groove of the locking plate 4. One end of the pressing plate 402 is fixedly connected to one side of the locking block 401.

[0028] It further includes a telescopic shell 5. The two sides of the outer shell 1 are hinged with the telescopic shell 5. One side of the two telescopic shells 5 is slidably connected with a limiting shell 501. A first handle is fixedly connected to one side of the limiting shell 501. A number of second chutes are opened in the limiting shell 501. A convex block 502 is slidably connected in the second chute of the limiting shell 501. One side of the convex block 502 is a smooth surface and the other side is a flat surface. A second elastic member is connected between the second chute of the limiting shell 501 and the convex block 502. The second elastic member is a spring.

[0029] It further includes a pull plate 504. The pull plate 504 is slidably connected inside the telescopic shell 5. Slide columns 503 are fixedly connected to both sides of the pull plate 504. One of the slide columns 503 is slidably connected with the telescopic shell 5. The other slide column 503 can contact the convex block 502 when moving. A second handle is fixedly connected to the top of the pull plate 504. An L-shaped rod 505 is fixedly connected to one side of the telescopic shell 5. The L-shaped rod 505 can contact the locking block 401 and the locking plate 4 when moving. The cooperation of the locking block 401 and the locking plate 4 can limit the L-shaped rod 505.

[0030] It further includes a connecting block 6. Connecting blocks 6 are symmetrically and fixedly connected to both sides of the outer shell 1. The connecting blocks 6 are symmetrically slidably connected with clamping plates 601. A reciprocating lead screw 602 is threadedly connected to the two clamping plates 601. A rotating handle 603 is fixedly connected to one end of the reciprocating lead screw 602. A moving wheel 604 is rotatably connected to the circumferential surface of the reciprocating lead screw 602. Four moving wheels 604 are provided.

[0031] When the beam formwork needs to be supported, the construction workers push the integral device to the appropriate position, and then the construction workers rotate the handle 603. The handle 603 drives the reciprocating lead screw 602 to rotate, and drives the two clamping plates 601 to approach each other to lock the moving wheels 604, making the device in an immovable state. Initially, the L-shaped rod 505 is in a clamped state between the locking plate 4 and the locking block 401, and the first elastic member is in a compressed state. The locking block 401 limits the L-shaped rod 505. Then, the construction workers drive the locking block 401 to descend by pressing the pressing plate 402. The locking block 401 releases the restriction on the L-shaped rod 505. The pull plate 504 is pulled out by manually pulling the second handle, and the pull plate 504 is pressed downward to make the pull plate 504 inclined. The inclination of the pull plate 504 drives the telescopic housing 5 and the L-shaped rod 505 to rotate and fit with the ground. At the same time, the sliding column 503 moves and squeezes the sliding surface of the convex block 502. At this time, the convex block 502 is forced to move into the second chute, and the convex block 502 squeezes the second elastic member to make it contract. By the pull plate 504 fitting with the ground, the pull plate 504 can increase the contact area of the bottom of the device with the ground and prevent the device from tilting. The flat surface of the convex block 502 limits the sliding column 503. The hydraulic rod 101 is started, and the output end of the hydraulic rod 101 drives the cross plate 102 to move upward. Then, the driving motor 2 is started, and the output shaft of the driving motor 2 drives the long plate 201 to rotate. Initially, the first support plate 301 and the two second support plates 302 are in an overlapping state. By the rotation of the long plate 201, the two connecting rods 205 are unfolded, and the connecting rods 205 drive the support blocks 206 to move away from each other. The two support blocks 206 respectively drive the two first support plates 301 to move away from each other. At this time, the long plate 201 drives the second support plate 302 to rotate through the fixed column 202. Initially, the sliding rod 204 is located at the first chute. When the sliding rod 204 moves into the inclined chute of the annular ring 203, the sliding rod 204 drives the second support plate 302 to descend. The second support plate 302 drives the fixed column 202 to move downward in the two through holes opened on the long plate 201. At this time, the second support plate 302 rotates 90 degrees downward and contacts the two separated first support plates 301. The output shaft of the driving motor 2 stops rotating. At this time, the two first support plates 301 and the second support plate 302 are at the same level. The two first support plates 301 are respectively in contact with the two triangular support plates 3. The triangular support plates 3 can better support the two first support plates 301. The output ends of the four hydraulic rods 101 drive the cross plate 102 to move upward. The cross plate 102 drives the two first support plates 301 and the second support plate 302 to move upward and fit with the beam formwork. The first support plate 301 and the second support plate 302 cooperate to increase the contact area with the beam formwork and support it.

[0032] When the device needs to contract, start the hydraulic rod 101. The end of the hydraulic rod 101 drives the cross plate 102 to descend. Then start the drive motor 2. The output shaft of the drive motor 2 drives the long plate 201 to rotate in the reverse direction. The reverse rotation of the long plate 201 drives the two connecting rods 205 to reset. The support block 206 drives the two first support plates 301 to approach each other through the two connecting rods 205 respectively. The two first support plates 301 are separated from the triangular support plate 3. At the same time, the rotation of the long plate 201 drives the two fixed columns 202 to rotate. The rotation of the two fixed columns 202 causes the second support plate 302 to drive the two sliding rods 204 to move in the inclined grooves. The two sliding rods 204 move upward along the edge of the inclined grooves. The sliding rods 204 drive the second support plate 302 to move upward and reset. Subsequently, the second support plate 302 is located above the two first support plates 301 to complete the reset. At this time, the two first support plates 301 and the second support plate 302 are reset. Turn off the drive motor 2. Then the construction worker pulls the first handle, and drives the convex block 502 to move synchronously through the limiting shell 501, so that the convex block 502 releases the limit on the sliding column 503. Then push and rotate the second handle to reset the pull plate 504. When the telescopic shell 5 is about to fit with the outer shell 1, the L-shaped rod 505 will squeeze the inclined surface of the locking block 401. The locking block 401 moves downward, and the first elastic member is compressed by force. The locking block 401 abuts against the L-shaped rod 505 and limits the telescopic shell 5. Subsequently, the construction worker rotates the knob 603 to release the limit on the moving wheel 604.
