Description

Technical Field

[0001] The utility model relates to a formwork structure for a cantilevered corridor, belonging to the technical field of construction. Background Art

[0002] During the use of the cantilever corridor, the wooden formwork needs to be supported by a supporting structure. The end of the beam at the bottom of the cantilever corridor is usually an upward inclined surface. At this time, the wooden formwork at the inclined surface of the beam end also needs to be arranged in an inclined shape. For high-rise buildings, there is often no support point directly below the end of the cantilever corridor. At this time, it is difficult to support the supporting structure at the bottom of the wooden formwork corresponding to the inclined surface of the beam end. Moreover, according to the different designs of the beam, the inclination angle of the inclined surface of the beam end is different. There is no supporting structure of suitable length to support it, which increases the difficulty of formwork erection. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a formwork structure for a cantilevered corridor to solve the problems raised in the above-mentioned background technology. The utility model supports the wooden formwork on the inclined planes with different inclination angles at the end of the bottom beam of the cantilevered corridor, thereby reducing the difficulty of erecting the formwork.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a formwork structure of a cantilever corridor, comprising a base plate, wherein one side of the upper surface of the base plate is evenly provided with a plurality of fixing holes, and a column rod is rotatably installed on the side of the upper surface of the base plate away from the fixing holes, a threaded hole is provided at the middle position of the upper surface of the column rod, a stud is threadedly connected in the threaded hole, and a connecting plate for connecting the wooden formwork is installed on the upper end of the stud. A plurality of small holes for inserting iron nails are evenly provided on one side of the connecting plate, and a pin hole for inserting an extension rod is provided on the outer surface of the end of the stud close to the connecting plate, and a hollow tube is installed on the outer surface of the upper end of the column rod through a rotating part, and an adjusting rod is inserted in the hollow tube, and the outer surface of the end of the hollow tube away from the column rod is threadedly connected with a positioning screw for limiting the relative position of the adjusting rod and the hollow tube, and the end of the adjusting rod at the outer side of the hollow tube is connected to the base plate through a connecting part.

[0005] Furthermore, the rotating part includes a rod head, a rod head is connected and fixed to the outer surface of the upper end of the column, a pipe sleeve is provided on the rod head, one end of the hollow tube is connected and fixed to the pipe sleeve, a threaded blind hole is provided on the side of the rod head away from the column, a threaded head is connected to the threaded blind hole, and the end of the threaded head outside the threaded blind hole is connected and fixed to a limit plate for limiting the pipe sleeve on the rod head.

[0006] Furthermore, a disc is glued to the innermost side of the threaded blind hole, a spring is installed on one side of the disc, and a plug for sealing the open end of the threaded blind hole is installed at the end of the spring away from the disc, and the plug is slidably installed in the threaded blind hole.

[0007] Furthermore, a hexahedron for clamping a wrench is connected and fixed to the middle position of the side of the limiting disk facing away from the threaded head, and the side of the hexahedron facing away from the limiting disk is recessed to form an inner hexagonal hole for inserting an inner hexagonal wrench.

[0008] Furthermore, the connecting part includes a support plate, and a support plate is installed on the side of the upper surface of the base plate close to the fixing hole. A first through-hole is provided at the upper position of one side surface of the support plate, and a second through-hole matching the first through-hole is provided at one end of the adjusting rod located outside the hollow tube. A pin rod is inserted into the channel formed by the first through-hole and the second through-hole, and a nut is threadedly connected to one end of the pin rod.

[0009] Furthermore, a U-shaped seat is installed at the lower end of the column through a rotating shaft, and the U-shaped seat is installed on the upper surface of the base plate. A rib is installed at the lower position of one side of the U-shaped seat. The rib is arranged along the length direction of the base plate, and the rib is connected and fixed to the base plate.

[0010] Furthermore, a threaded sleeve is fixedly connected to the outer surface of one end of the hollow tube away from the column, and the positioning screw is threadedly connected in the threaded sleeve.

[0011] Beneficial effects of the utility model:

[0012] 1. Install the base plate on the building, and extend one end of the base plate to just below the end of the beam at the bottom of the cantilevered corridor. Then adjust the length of the stud in the threaded hole so that the length of the structure formed by the stud and the column meets the requirements. Then adjust the angle between the column and the base plate so that the connecting plate fits the wooden formwork opposite to the inclined surface of the beam end, and use iron nails to connect the wooden formwork and the connecting plate. At this time, the structure formed by the stud and the column is arranged vertically with the wooden formwork corresponding to the inclined surface of the beam end. Because the angle between the column and the base plate can be adjusted, the wooden formwork on the inclined surfaces of different inclination angles of the beam end at the bottom of the cantilevered corridor can be supported, reducing the difficulty of formwork erection.

[0013] 2. After the connection between the connecting plate and the wooden formwork is completed, adjust the length of the adjusting rod in the hollow tube so that one end of the adjusting rod is connected to the base plate through the pin rod, and then use the positioning screw to limit the relative position of the adjusting rod and the hollow tube. At this time, the structure formed by the adjusting rod and the hollow tube can support the column and improve the stability of the structure. When removing the nails on the connecting plate, the hollow tube and the adjusting rod can prevent the structure formed by the studs and columns from falling suddenly due to loss of support, thereby improving safety.

[0014] 3. The sleeve installed at one end of the hollow tube is placed on the rod head, and the threaded head on the limit plate is screwed into the threaded blind hole. When the hollow tube is rotated, the hollow tube drives the sleeve to rotate around the rod head, thereby realizing the rotational connection between the hollow tube and the column rod. After the threaded head is disengaged from the threaded blind hole, it is convenient to remove the sleeve from the rod head, and convenient for separate storage of hollow tubes, columns and other components.

[0015] 4. When the threaded head is screwed into the threaded blind hole, the threaded head squeezes the plug, and the plug squeezes the spring, causing the spring to produce elastic deformation. When the threaded head is out of the threaded blind hole, the spring rebound force causes the plug to move flush with the open end of the threaded blind hole, thereby achieving real-time sealing of the threaded blind hole and preventing debris from entering the threaded blind hole at will.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See Figure 1 and Figure 3 , a threaded hole is provided in the middle of the upper surface of the column 6, and a stud 10 is connected with a thread in the threaded hole. A connecting plate 11 for connecting to the wooden formwork is installed on the upper end of the stud 10. A plurality of small holes for inserting nails are evenly provided on one side of the connecting plate 11. A pin hole 12 is provided on the outer surface of one end of the stud 10 near the connecting plate 11, so that the extension rod is inserted into the pin hole 12, which makes it easy to rotate the stud 10 by using the extension rod, so that the base plate 1 is installed on the building body, and one end of the base plate 1 extends to just below the end of the beam at the bottom of the cantilevered corridor, and then adjust the stud 10 in the threaded hole The length of the hole is adjusted so that the length of the structure formed by the stud 10 and the column 6 meets the needs, and then the angle between the column 6 and the base plate 1 is adjusted so that the connecting plate 11 is fitted with the wooden formwork opposite to the inclined surface of the beam end, and the wooden formwork and the connecting plate 11 are connected with iron nails. At this time, the structure formed by the stud 10 and the column 6 is arranged vertically with the wooden formwork corresponding to the inclined surface of the beam end. Since the angle between the column 6 and the base plate 1 can be adjusted, the wooden formwork on the inclined surfaces of different inclination angles of the beam end at the bottom of the cantilevered corridor can be supported, thereby reducing the difficulty of formwork erection.

[0026] See Figure 1-Figure 5, the outer surface of the upper end of the column 6 is connected and fixed with a rod head 18, a pipe sleeve 9 is provided on the rod head 18, one end of the hollow tube 13 is connected and fixed to the pipe sleeve 9, and a threaded blind hole 23 is provided on the side of the rod head 18 away from the column 6. A threaded head 24 is connected to the threaded blind hole 23. The threaded head 24 is connected to the end of the threaded blind hole 23 outside the threaded blind hole 23. A limiting plate 8 for limiting the pipe sleeve 9 on the rod head 18 is connected and fixed to the middle position of the side of the limiting plate 8 away from the threaded head 24. A hexahedron 7 for clamping a wrench is fixed. The side of the hexahedron 7 away from the limiting plate 8 is recessed to form a An adjusting rod 14 is inserted into the hexagonal hole for inserting the hexagonal wrench, and the outer surface of the hollow tube 13 away from the column 6 is connected to the fixed threaded sleeve 19, which is internally threaded and connected to a positioning screw 20 for limiting the relative position of the adjusting rod 14 and the hollow tube 13. A support plate 2 is installed on the side of the upper surface of the base plate 1 close to the fixing hole 16. A first through-hole is opened at the upper position of one side surface of the support plate 2. A second through-hole matching the first through-hole is opened at the end of the adjusting rod 14 on the outside of the hollow tube 13, and a pin rod 1 is inserted in the channel formed by the first through-hole and the second through-hole. 5, the nut 3 is threadedly connected to one end of the pin rod 15 to complete the relative position restriction of one end of the adjusting rod 14 and the base plate 1. After the connection between the connecting plate 11 and the wooden template is completed, the length of the adjusting rod 14 in the hollow tube 13 is adjusted so that one end of the adjusting rod 14 is connected to the base plate 1 through the pin rod 15. Then, the positioning screw 20 is used to limit the relative position of the adjusting rod 14 and the hollow tube 13. At this time, the structure formed by the adjusting rod 14 and the hollow tube 13 realizes the support of the column 6 and improves the stability of the structure. When the nails on the connecting plate 11 are removed, the adjustment rod 14 is adjusted between the hollow tube 13 and the adjusting rod 6. Under the joint action of the rod 14, the structure formed by the stud 10 and the column 6 is prevented from suddenly falling due to loss of support, thereby improving safety. The pipe sleeve 9 installed at one end of the hollow tube 13 is sleeved on the rod head 18, and the threaded head 24 on the limit plate 8 is screwed into the threaded blind hole 23. When the hollow tube 13 is rotated, the hollow tube 13 drives the pipe sleeve 9 to rotate around the rod head 18, thereby realizing the rotational connection between the hollow tube 13 and the column 6. After the threaded head 24 is disengaged from the threaded blind hole 23, it is convenient to remove the pipe sleeve 9 from the rod head 18, and conveniently store the hollow tube 13, the column 6 and other components separately.

The end of the spring 22 away from the disc 21 is installed with a plug 17 for sealing the open end of the threaded blind hole 23. The plug 17 is slidably installed in the threaded blind hole 23, and the disc 21 is restricted in the threaded blind hole 23 by glue, so that one end of the spring 22 is restricted in the threaded blind hole 23. When the threaded head 24 is screwed into the threaded blind hole 23, the threaded head 24 squeezes the plug 17, and the plug 17 squeezes the spring 22, causing the spring 22 to produce elastic deformation. When the threaded head 24 is disengaged from the threaded blind hole 23, under the action of the rebound force of the spring 22, the plug 17 moves to be flush with the open end of the threaded blind hole 23, thereby realizing real-time blocking of the threaded blind hole 23 and preventing debris from entering the threaded blind hole 23 at will.
