Abstract
Description
Technical Field
[0001] This application relates to the field of building construction, specifically to an adjustable ladder cage fixing clamp device. Background Technology
[0002] During construction, ladder cages are a common safety device. Their robust and durable structure can withstand multiple pressures, ensuring the safety of construction workers operating at different heights. The installation of the ladder cage involves determining the foundation location based on the cap beam height and cage dimensions. Reinforcing bars or anchor bolts are pre-embedded in the foundation, and the bottom of the ladder cage is welded or bolted to the pre-embedded parts. After the bottom of the ladder cage is connected to the pre-embedded parts, the foundation is checked to ensure it is secure and reliable, guaranteeing the stability of the ladder cage. When the height of the ladder cage exceeds a certain value, its stability needs to be enhanced. Common methods include using pre-embedded parts for welding, expansion bolt fixing, through-wall bolt connections, or using guy ropes to improve the stability of the ladder cage.
[0003] Existing technologies propose using clamps and tie rods to connect cylindrical piers and ladder cages to improve the stability of the ladder cage. For example, Chinese Patent Publication No. CN215714642U describes a clamp device for connecting cylindrical piers and ladder cages. This device consists of two half-clamps, each containing a strip-shaped component and ear plates for fixing the strip-shaped component. An adjustment notch is provided between the middle section of the strip-shaped component and the ear plates, through which an adjusting threaded rod passes, and both ends are secured with nuts.
[0004] In existing publicly available technologies, the size of the clamp is adjusted using a screw or a positioning hoop to fit the dimensions of the round pier column. While this technology can adjust the clamp size to fit the round pier column, the contact area between the clamp and the pier column is small, and no protection is provided for the pier column's appearance. Furthermore, existing publicly available technologies rarely consider the connection between the round pier column and the ladder cage. Utility Model Content
[0005] The purpose of this utility model is to provide an adjustable ladder cage fixing clamp device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable ladder cage fixing clamp device is characterized in that it includes a clamp plate and a connector for connecting the ladder cage. The clamp plate includes a clamp body and adjustable top rods disposed within the clamp. Four adjustable top rods are centrally distributed on the inner wall of the clamp body. Each adjustable top rod includes an internal threaded sleeve, an external threaded rod, and an arc-shaped top support. The four arc-shaped top supports form a concentric circle. The connector includes two sets of adjustable tie rod assemblies symmetrically disposed on both sides of the clamp plate. Each set of adjustable tie rod assemblies includes at least four adjustable tie rods. Each adjustable tie rod includes a clamp connecting piece, a screw rod one, a threaded sleeve one, a threaded rod two, a threaded sleeve two, and a ladder cage connecting piece connected in sequence.
[0007] More preferably, the screw rod one is connected to the clamping connecting piece by double nuts, the threaded sleeve two is welded and fixed to the ladder cage connecting piece, and the screw rod one, threaded sleeve one, threaded rod two, and threaded sleeve two are sequentially threaded together.
[0008] Furthermore, the clamp body is composed of two semi-circular clamps, which are connected together and fixed by bolts. Four adjustable tie rods are connected in pairs and fixed to the two side plates of the semi-circular clamps respectively.
[0009] Furthermore, the semicircular clamp consists of two semicircular steel plates spaced apart vertically and an end plate fixed to the ends of the two semicircular steel plates. The end plates of the semicircular clamp are stacked and connected by bolts.
[0010] Furthermore, a stiffening plate is connected between the two semi-circular steel plates, and the internally threaded sleeve is connected between the two stiffening plates.
[0011] Furthermore, the stiffening plate is provided with a strip-shaped through hole, and the end of the internally threaded sleeve is provided with at least two bolt holes. The strip-shaped through hole and the bolt holes are connected by bolts.
[0012] In addition, a rubber anti-slip pad is affixed to the arc-shaped top support.
[0013] More preferably, the two sets of adjustable tie rod assemblies are connected to the same ladder cage connecting piece.
[0014] Compared with the prior art, this utility model has the following features and beneficial effects: This application increases the contact area between the clamp and the circular pier by setting multiple threaded sleeves, threaded rods, limiting clamps, and rubber pads, resulting in better stress performance. The addition of rubber pads increases the friction between the clamp and the pier and protects the aesthetic appearance of the pier. An adjustable tie rod device is set up, which can adjust the distance between the clamp and the ladder cage by the length of the screw inserted into the threaded sleeve. It has the characteristics of safety and applicability, and has good promotion and practical value. After widespread application, it will generate good economic benefits.
[0015] This application features multiple arc-shaped top supports, increasing the contact area between the clamp and the pier column and improving mechanical performance. Rubber pads are added to protect the appearance of the pier column, and an adjustable tie rod device is added to allow the adjustable ladder cage fixing clamp device to adjust the distance between the clamp and the ladder cage, thus improving the applicability of the adjustable ladder cage fixing clamp device.
[0016] This application adjusts the size of the clamp by screwing the inner screw rod into the threaded sleeve. The two half-clamps are connected together by bolts and nuts, which connects the clamp to the pier. The clamp and the ladder cage are connected by an adjustable tie rod device and a ladder cage connecting device. The distance between the clamp and the ladder cage can be adjusted by the length of the screw rod inserted into the threaded sleeve, thereby improving the stability of the ladder cage.

[0021] Example 1 An adjustable ladder cage fixing clamp device includes a clamp plate 1 and a connector 2 for connecting the ladder cage. The clamp plate 1 includes a clamp body 11 and adjustable top rods 12 disposed within the clamp. Four adjustable top rods 12 are centrally distributed on the inner wall of the clamp body 11. Each adjustable top rod 12 includes an internally threaded sleeve, an externally threaded rod, and an arc-shaped top support, with the four arc-shaped top supports forming a concentric circle. The connector 2 includes two sets of adjustable tie rod assemblies symmetrically disposed on both sides of the clamp plate 1, each set being adjustable. The tie rod assembly includes at least four adjustable tie rods. Each adjustable tie rod comprises a clamp connecting plate 21, a screw rod 22, a threaded sleeve 23, a threaded rod 24, a threaded sleeve 25, and a cage connecting plate 26, connected sequentially. The screw rod 22 is connected to the clamp connecting plate 21 via double nuts 27. The threaded sleeve 25 is welded to the cage connecting plate 26. The screw rod 22, threaded sleeve 23, threaded rod 24, and threaded sleeve 25 are sequentially threaded together. The clamp body 11 consists of two semi-circular clamps, which are bolted together. The four adjustable tie rods are fixed in pairs to the two side plates of the semi-circular clamps.
[0022] In use, first adjust the four adjustable top rods 12 to match the diameter of the pier column, then fix the clamp plate 1, and then connect the ladder cage. Specifically, first screw the threaded rod inside the clamp into the threaded tube to the specified depth to match the clamp size with the pier column size. Then, connect and fix the upper and lower clamps with bolts. Connect one end of the adjustable tie rod device to the clamp, and connect the threaded sleeve in the adjustable tie rod device. Connect the other end of the threaded rod to the threaded sleeve in the ladder cage connection device. The threaded tube in the ladder cage connection device can be customized as one piece with the steel plate. Fix the ladder cage connection device in the ladder cage with bolts.
[0023] This embodiment consists of an upper clamp, a lower clamp, an adjustable tie rod, and a ladder cage connecting device. The upper and lower clamps are connected at both ends with high-strength bolts. Each clamp has two diameter adjustable devices, symmetrically distributed. Each diameter adjustable device includes a threaded sleeve, a threaded rod, a limiting clamp, and a rubber pad. The threaded sleeve connects to the inside of the clamp, and the threaded rod is inserted into the threaded sleeve. The threaded rod connects to the limiting clamp, and a rubber pad is installed on the limiting clamp. This device allows adjustment of the clamp size to match the pier column size by the length of the threaded rod inserted into the threaded sleeve. The adjustable tie rod device includes a threaded sleeve and a screw. This device allows adjustment of the distance between the clamp and the ladder cage by the length of the screw inserted into the threaded sleeve. The ladder cage connecting device includes a steel plate, a threaded sleeve, and bolts. The steel plate is fixed to a suitable position in the ladder cage by the bolts. A threaded sleeve is connected to the outside of the steel plate, and the threaded sleeve is connected to the screw of the tie rod device.
[0024] Example 2 The semicircular clamp consists of two semicircular steel plates 13 spaced apart vertically and end plates fixed to the ends of the two semicircular steel plates 13. The end plates of the semicircular clamp are stacked and connected by bolts. A stiffening plate 3 is connected between the two semicircular steel plates 13. An internal threaded sleeve is connected between the two stiffening plates 3. The stiffening plate 3 has a strip-shaped through hole 31. The end of the internal threaded sleeve has at least two bolt holes. The strip-shaped through hole 31 is connected to the bolt holes by bolts. A rubber anti-slip pad is attached to the arc-shaped top support. Two sets of adjustable tie rod assemblies are connected to the same ladder cage connecting piece 26.
[0025] In Example 2, the clamp can be fixed first, and then the adjustable top rod can be adjusted. At the same time, the relative position of the adjustable top rod and the strip-shaped through hole can be adjusted for more precise adjustment so that the arc-shaped top support abuts against the outer wall of the pier column.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
