Description

Technical Field

[0001] This utility model belongs to the technical field of engineering construction auxiliary equipment, specifically relating to a prefabricated adjustable prestressed tensioning construction frame. Background Technology

[0002] Prestressing tensioning is the core process in prestressed engineering. It generally uses steel strands, jacks, anchor plates, and wedges to actively apply tension to generate internal stress in the structure before it bears a load, thereby improving the structural performance.

[0003] The existing prestressed tensioning construction frame is temporarily assembled using scaffolding, which poses significant safety hazards. Most tensioning frames are heavy, immobile, and cannot be adjusted, resulting in low construction efficiency and a large amount of labor consumption. Therefore, a new type of prestressed tensioning frame is needed to solve the above problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model discloses a prefabricated adjustable prestressed tensioning construction frame, which can flexibly move to tension components, and its height, depth, and width can all be adjusted. The structure is scientifically sound and practical, with high safety and flexibility.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An assembled adjustable prestressed tensioning construction frame includes a square frame body, which is composed of four support columns, longitudinal struts, and transverse struts. A replaceable short section is provided above the support columns, and two transverse guide rails are provided above the replaceable short sections. Each transverse guide rail is provided with two transverse sliding wheel sets. Two longitudinal guide rails are hung below the transverse sliding wheel sets. The longitudinal guide rails extend out of the frame body and are provided with a longitudinal sliding wheel set. The longitudinal struts and transverse struts are sleeve pipes.

[0006] As an improvement of this utility model, the frame is equipped with rollers at the bottom, and the rollers are equipped with brake pads.

[0007] As an improvement of this utility model, the support column, longitudinal strut, transverse strut, and replaceable short section are connected by bolts.

[0008] As an improvement of this utility model, a placement plate is provided at the bottom of the frame.

[0009] As an improvement of this utility model, a lifting lug is provided above the transverse guide rail.

[0010] As an improvement of this utility model, both the transverse guide rail and the longitudinal guide rail are I-beams.

[0011] As an improvement of this utility model, limiting plates are provided at both ends of the transverse guide rail and the longitudinal guide rail.

[0012] As an improvement of this utility model, a safety warning sign is provided on the other side of the frame.

[0013] The beneficial effects of this utility model are as follows: (1) The manual hoist is hung on the longitudinal sliding wheel group, and the prestressed jack is connected below it. The position of the longitudinal sliding wheel group can be adjusted laterally and longitudinally according to the position of the jack to ensure the accurate force direction. (2) The overall height can be adjusted by replacing the replaceable short sections above the support columns of the frame; (3) The longitudinal struts are sleeves, which can adjust the width of the frame and the stress on the longitudinal guide rails; (4) The main components are assembled and connected by bolts, making them easy to assemble and disassemble and highly flexible.

[0019] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0020] As shown in the figure, the prefabricated adjustable prestressed tensioning construction frame of this utility model includes a square frame body 1. The frame body 1 is composed of four support columns 2, longitudinal struts 3, and transverse struts 4. A replaceable short section 5 is provided above the support columns. Two transverse guide rails 6 are provided above the replaceable short section 5. Two transverse sliding wheel sets 7 are provided on each transverse sliding wheel set 7. Two longitudinal guide rails 8 are hung below the transverse sliding wheel sets 7. The longitudinal guide rails 8 extend outside the frame body 1. A longitudinal sliding wheel set 9 is provided on the longitudinal guide rail 8. The longitudinal struts 3 and transverse struts 4 are sleeve pipes.

[0021] The present invention describes a prefabricated adjustable prestressed tensioning construction frame. During operation, the frame is placed above two prestressed jacks, and the horizontal sliding wheel group 7 and the vertical sliding wheel group 9 are manually pulled to adjust the horizontal and vertical directions, ensuring vertical force and reasonable tensioning. The present invention is prefabricated and its height, depth, and width are adjustable.

[0022] Each support column is equipped with a replaceable short section 5. There are several models of these replaceable short sections 5 with different lengths. When it is necessary to adjust the height, a longer short section is used. When it is necessary to adjust the height, a shorter short section is used. The choice depends on the site conditions.

[0023] The longitudinal support rod 3 described in this utility model is a sleeved square tube with holes drilled every 10cm and equipped with locking bolts, such as... Figure 4 As shown, the frame depth can be adjusted to regulate the stress on the longitudinal guide rails.

[0024] The longitudinal support rod 4 described in this utility model is also a sleeved square tube with holes drilled every 10cm and equipped with locking bolts, which can adjust the width of the frame. When adjusting, the longitudinal support rod 4 can be lengthened or shortened, and the transverse guide rail 6 can be replaced with the corresponding length.

[0025] Additionally, rollers 10 are installed below the frame 1. These rollers 10 are equipped with brake pads, which can be pushed near the component when needed, and then the rollers can be locked to begin tensioning, making it convenient and practical. The support column 2, longitudinal strut 3, transverse strut 4, and replaceable short section 5 of this utility model are connected by bolts 15. When not in use, they can be removed and stored without taking up too much space.

[0026] This utility model has a placement plate 11 (laid on the longitudinal support rod 3) under the frame 1, on which the tools to be used can be placed. A safety warning sign 14 is provided on the other side of the frame 1, which also serves to prevent the tools from slipping.

[0027] The present invention has a lifting lug 12 on the upper part of the transverse guide rail 6, which facilitates the lifting of the transverse guide rail 6 and the installation of the replaceable short section 5.

[0028] Both the transverse guide rail 6 and the longitudinal guide rail 8 of this utility model are I-beams, which facilitates the sliding of the wheel set. Limiting plates 13 are provided at both ends of the transverse guide rail 6 and the longitudinal guide rail 8 to ensure that the wheel set will not fall and increase safety.

[0029] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
