Description

Technical Field

[0001] The invention relates to the technical field of civil building wall construction, in particular to a radiation-proof concrete formwork supporting structure. Background Art

[0002] Radiation-proof concrete is a concrete with a large bulk density, the ability to shield Y-rays, X-rays or neutron radiation, and is not easily penetrated by radiation.

[0003] In modern civil and industrial buildings, there are many medical radiation instrument rooms, such as X-ray rooms, CT monitoring rooms, MRI rooms, etc. Industrial flaw detection rooms often involve large-volume radiation-proof concrete walls. Since the density and thickness of radiation-proof concrete are greater than those of ordinary concrete, the formwork requirements for large and extra-thick radiation-proof concrete walls are higher, that is, the formwork and support system must have sufficient bearing capacity, rigidity and stability to reliably withstand the deadweight of the newly poured concrete, lateral pressure and construction loads during the construction process.

[0004] Concrete formwork tension bolts, wall sleeves, structural reserved holes and other parts are the weak links of the entire concrete radiation protection structure system. According to the characteristics of radiation rays propagating in a straight line, in order to eliminate the weakening effect of weak links on the entire radiation protection structure, it is required that weak links must not be directly penetrated. For tension bolts, threaded rod tension bolts are usually used and left in the concrete structure to prevent radiation leakage; for wall sleeves and structural reserved holes, specific treatment measures are taken to set them in a "maze-like" manner to prevent radiation leakage.

[0005] When using tension bolts, the distance between the two formworks is relatively large, so there is a possibility that the bolts are not long enough. The process of transporting the bolts consumes a lot of manpower and material resources. If the length is not enough, the concrete cannot be properly supported. The separate treatment of the formwork tension bolts, wall sleeves, and structural reserved holes does not reduce the number of weak points in the concrete structure and still poses a certain risk of radiation leakage. In addition, the gap between the formworks will cause concrete to flow out of the gap when pouring concrete. In summary, the present invention proposes a radiation-proof concrete formwork support structure. Summary of the Invention

[0029] The present invention provides a radiation-proof concrete formwork support structure, comprising: a wooden formwork 1, a wooden formwork 2, and a base 3. The structure is characterized in that: the wooden formwork 1 and the wooden formwork 2 are respectively arranged on the base 3, the base 3 is required to be stable, the wooden formwork 1 and the wooden formwork 2 are respectively arranged in two groups opposite to each other, the wooden formwork 1 is connected to the wooden formwork 2, and serves to resist the flow of concrete.

A caulking device 7 is provided at the connection between the wooden formwork 1 and the wooden formwork 2 to prevent concrete from flowing out of the connection between the wooden formwork 1 and the wooden formwork 2 when pouring concrete, thereby causing waste of concrete.

[0030] The connecting device 5 includes a slide 50, a sliding block 52, a screw 57 and a motor 1 58. The slide 50 is arranged at the lower end of the inner wall of the reserved sleeve 4 of the hole. A long groove 51 is opened on the slide 50. The sliding block 52 is slidably connected in the long groove 51. The top of the sliding block 52 is connected to the fixed block 1 53. The top of the fixed block 1 53 is provided with a circular groove 1 54 and a circular groove 2 55. A rotating device 56 is respectively provided in the circular groove 1 54 and the circular groove 2 55. A screw 57 passes through the sliding block 52, and one end of the screw 57 is connected to the motor 1 58.

[0031] As an embodiment of the present invention, the motor 1 58 drives the screw 57 to rotate, thereby driving the sliding block 52 to reciprocate back and forth under the rotation of the screw 57, that is, the circular groove 1 54 and the circular groove 2 55 also reciprocate back and forth on the screw 57, and during the movement, the direction of the circular groove 1 54 and the circular groove 2 55 does not change.

[0032] The rotating device 56 includes a cylindrical groove 560, a second connecting rod 564, a second gear 566 and a second motor 567. A cylindrical body 561 is sleeved on the cylindrical groove 560, and a wedge block 562 is sleeved on the cylindrical body 561. The wedge block 562 includes a first wedge block 5621 and a second wedge block 5622.

A gear 1 565 is sleeved on the cylindrical body 561, and the gear 1 565 is meshed with the gear 2 566. The gear 2 566 is fixedly connected to the second motor 567, and the second motor 567 is fixedly connected to the fixed block 1 53.

[0033] As an embodiment of the present invention, motor two 567 drives gear two 566 to rotate. Since gear one 565 is meshed and connected with gear two 566, gear one 565 rotates in the opposite direction to gear two 566. While gear one 565 moves, it drives cylinder 561 and wedge block 562 to rotate in the same direction as gear one 565, and drives connecting rod one 563, connecting rod two 564 and connecting rod three 568 to rotate in the same direction as gear one 565.

[0034] The connecting device 7 includes a fixed panel 1 70, a fixed panel 2 71, a connecting panel 1 73, a fixed block 2 74 and a fixed block 3 75. The fixed panel 1 70 is fixedly connected to the fixed panel 2 71. A connecting panel 1 73 is provided between the fixed panel 1 70 and the fixed panel 2 71. The fixed block 2 74 is fixedly connected to the fixed block 3 75. The other end of the connecting panel 1 73 is connected to the connection between the fixed block 2 74 and the fixed block 3 75. Connecting panels 2 76 are respectively provided on both sides of the connecting panel 1 73. Hydraulic telescopic rods 72 are respectively provided on the same side of the upper and lower ends of the fixed panel 1 70. One end of the hydraulic telescopic rod 72 is connected to the fixed panel 1 70, and the other end of the hydraulic telescopic rod 72 is connected to one side of the connecting panel 2 76. The hydraulic telescopic rod 72 is symmetrical with the connecting panel 1 73 as the center of symmetry.

[0035] As an embodiment of the present invention, there can be several connecting panels 76, and a lock (not shown in the figure) is provided between each connecting panel 76. When the gap between fixed panel 1 70 and fixed panel 2 71 is too large or too small, the connection condition of the lock can be manually adjusted, and then the connecting panel 2 76 can be driven to move by the hydraulic telescopic rod 72, so that the thickness of connecting panel 1 73 and connecting panel 2 76 matches the gap between fixed panel 1 70 and fixed panel 2 71.

[0036] Specific working principle: The hydraulic telescopic rod 72 contracts, driving the connecting panel 2 76 to move toward the fixed panel 1 70 and the fixed panel 2 71 respectively.

[0037] As an embodiment of the present invention, a water stop 8, a wedge-shaped fastener 9 and a nut 10 are respectively provided on the tension bolt 6. The function of the water stop 8 is to prevent water from entering; the function of the wedge-shaped fastener 9 is to fix the position of the tension bolt 6, and at the same time cooperate with the function of the nut 10 to fix the tension bolt 6 to prevent it from loosening and affecting the overall function of the device.

[0038] As an embodiment of the present invention, the inner walls of the circular groove 1 54 and the circular groove 2 55 are respectively provided with threads, and the two thread directions are opposite. If the length of the tension bolt 6 is not enough, two types of tension bolts 6 are required to work in combination, and the two types of tension bolts 6 need to be connected in combination, then the tension bolts 6 are respectively threadedly connected to the circular groove 1 54 and the circular groove 2 55. If the threads of the circular groove 1 54 and the circular groove 2 55 are in the same direction, but the relative rotation directions of the tension bolts are different, then the relative tension bolts 6 cannot perform their fixed connection function.

[0039] As an embodiment of the present invention, the cylinder 561, the wedge block 562, the connecting rod 1 563, the connecting rod 2 564 and the connecting rod 3 568 are distributed in an array with the cylindrical groove 560 as the center of the circle. Then, the connecting rod 1 563, the connecting rod 2 564 and the connecting rod 3 568 are rotated into the inside of the cylindrical groove 560, thereby resisting the tension bolt 6 from continuing to move forward. At the same time, because of the blocking effect in front, it is beneficial to tighten the tension bolt 6, which is beneficial to the threaded connection of the tension bolt 6 with the circular groove 1 54 or the circular groove 2 55.

[0040] As an embodiment of the present invention, several rows of reserved hole sleeves 4 are provided on the wooden template 1 and several rows of reserved hole sleeves 4 are provided on the wooden template 2 2. The two are connected to each other but not through. The reserved hole sleeves 4 on the wooden template 1 and the wooden template 2 2 are connected by aluminum wire or other materials, which fix the entire device.

[0041] Specific working principle:

[0042] The wooden formwork 1 and the wooden formwork 2 are combined on the base 3 to form a rectangular shape. If there is a gap at the connection between the wooden formwork 1 and the wooden formwork 2, the caulking device 7 is placed between the connection between the two, that is, the position of the connecting panel 2 76 is adjusted to meet the thickness of the connecting panel 1 72 and the connecting panel 2 76 to meet the gap between the wooden formwork 1 and the wooden formwork 2, that is, there can be several connecting panels 2 76, and each connecting panel 2 76 is provided with a lock (not shown in the figure). When the gap between the fixed panel 1 70 and the fixed panel 2 71 is too large or too small, the connection condition of the lock can be manually adjusted, and then the connecting panel 2 76 can be driven to move by the hydraulic telescopic rod 72, so that the thickness of the connecting panel 1 73 and the connecting panel 2 76 matches the gap between the fixed panel 1 70 and the fixed panel 2 71.

[0043] Afterwards, several rows of hole reserved sleeves 4 are provided on the wooden formwork 1 and the wooden formwork 2 2 at equal distances and inclinations, and then the hole reserved sleeves 4 are connected by aluminum wire or other materials. Then, the tension bolts 6 are passed through the hole reserved sleeves 4, and finally, the wedge fasteners 9 and nuts 10 are used to work together to fix the tension bolts 6 to prevent them from loosening and affecting the overall function of the device.

[0044] When the remaining tension bolts 6 are not long enough, two tension bolts 6 can be used to connect the two tension bolts 6 to fix the entire device. The specific operation is as follows:

[0045] First, a tension bolt 6 is inserted into the reserved sleeve 4 in the hole, and then the motor 1 58 drives the shaft to rotate the screw 57, thereby driving the sliding block 52 to move forward (in the direction of the tension bolt 6 extending) under the rotation of the screw 57, that is, the circular groove 1 54 and the circular groove 2 55 also move forward on the screw 57, and during the movement, the direction of the circular groove 1 54 and the circular groove 2 55 does not change, and then the tension bolt 6 enters the circular groove 1 54.

[0046] When the tension bolt 6 enters the circular groove 1 54 , the positions of the connecting device 5 and the tension bolt 6 are determined. At this time, another tension bolt 6 is inserted through the other end of the reserved sleeve 4 through the hole, and the second tension bolt 6 is inserted into the circular groove 2 55 .

[0047] At this time, motor 2 567 drives gear 2 566 to rotate. Since gear 1 565 is meshed with gear 2 566, gear 1 565 rotates in the opposite direction to gear 2 566, and while gear 1 565 moves, it drives cylinder 561 and wedge block 562 to rotate in the same direction as gear 1 565, which drives connecting rod 1 563, connecting rod 2 564 and connecting rod 3 568 to rotate in the same direction as gear 1 565, so that the positions of connecting rod 1 563, connecting rod 2 564 and connecting rod 3 568 are in the cylindrical groove 560, which prevents the tension bolt 6 from continuing to move forward. At the same time, because it has a blocking effect in front, it is beneficial to tighten the tension bolt 6, which is beneficial to the threaded connection of the tension bolt 6 with circular groove 1 54 or circular groove 2 55. The two tension bolts 6 are manually rotated in different directions so that they are threadedly connected with circular groove 1 54 or circular groove 2 55.

[0048] When the two tension bolts 6 are rotated in different directions to be threadedly connected with the circular groove 1 54 or the circular groove 2 55, the positions of the two tension bolts 6 and the connecting device 5 are determined. At this time, the wedge fasteners 9 and nuts 10 on the two tension bolts 6 are manually rotated respectively to fix the tension bolts 6 to prevent them from loosening and affecting the overall function of the device.

[0049] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
