Description

Technical Field

[0001] The utility model relates to the technical field of steel cage processing equipment, in particular to a movable tire frame used for processing anti-slip pile steel cages. Background Art

[0002] Anti-slide piles are widely used in landslide control, but since the landslide itself is in an unstable state, there are great safety hazards in the use of manual digging. The "Catalogue of Construction Techniques, Equipment and Materials for Elimination of Production Safety Dangers in Highway and Waterway Engineering" formulated by the Ministry of Transport and the Ministry of Emergency Management lists manual digging piles as a restricted construction technology, and its use is restricted in areas with mechanical drilling conditions. Therefore, the subsequent use of mechanical drilling for anti-slide piles will be more and more common in actual engineering applications in the future. After mechanical drilling, due to the high density of the main reinforcement of the anti-slide pile section, most of the three main reinforcements are combined together on the side close to the landslide, and the spacing between the combinations is small. If the conventional bridge pile adopts the segmented hoisting construction process, when the sleeve is used at the segmented position, there is no space for tightening the steel bars and it is difficult to connect the steel bars tightly, a weak surface will be formed at the main reinforcement connection position, and the quality of the steel cage cannot be guaranteed. However, if the fixed tire frame is used to process the steel cage as a whole, the stirrups will be difficult to put in, which will seriously affect the construction progress. In the process of putting the stirrups, the linearity of the steel cage will be seriously damaged, affecting the quality of the steel cage, and the hole wall will be knocked during the hoisting process. Utility Model Content

If a fixed cradle is used to process the reinforcement cage as a whole, it will be difficult to put the stirrups in, which seriously affects the construction progress. In the process of putting the stirrups in, the linearity of the reinforcement cage will be seriously damaged, affecting the quality of the reinforcement cage, and the hole wall will be bumped during the lifting process into the hole.

The reinforcing hoop 5 is the skeleton of the upper main reinforcement and the lower positioning reinforcement 6, which enhances the overall stability of the steel cage later.

This structure provides stable support in multiple directions. In particular, the array arrangement of the longitudinal bars and the transverse bars and the locking and fixing by the connecting fasteners 1 greatly enhance the stability and load-bearing capacity of the entire tire frame. A three-dimensional tire frame structure is constructed by the combination of the longitudinal bars 2, the transverse bars 3 and the vertical bars 8. This structure provides stable support in multiple directions. In particular, the array arrangement of the longitudinal and transverse bars and the locking and fixing by the connecting fasteners 1 greatly enhance the stability and load-bearing capacity of the entire tire frame. The main reinforcement 7 is installed on the top of the tire frame, which not only enhances the load-bearing capacity of the top, but also helps to determine and maintain the shape and structure of the entire tire frame. The setting of the stiffening hoop 5 enhances the lateral stability of the tire frame, and the lower positioning rib 6 ensures the stability of the bottom of the tire frame. These elements work together to enable the tire frame to maintain its shape and position when subjected to external forces. The outer side of the tire frame is installed and positioned by the stirrups, which further enhances the overall stability and positioning accuracy of the tire frame.

[0023] In this embodiment, the scissors support 4 is arranged obliquely, and both ends are fixed at the connecting fasteners 1, so as to improve the strength of the tire frame and prevent looseness.

[0024] Specifically, the connecting fastener 1 includes a steel bar 11, the middle part of the steel bar 11 is wrapped around the connection between the longitudinal bar 2, the cross bar 3 and the vertical bar 8 of the tire frame, and the two ends of the steel bar 11 are connected with a pressure plate 13 to facilitate locking and fixing the connection between the longitudinal bar 2, the cross bar 3 and the vertical bar 8.

[0025] Furthermore, through holes are provided at both ends of the pressure plate 13 , and threaded ends 12 are provided at the ends of the steel bars 11 . The ends of the threaded ends 12 pass through the through holes and are equipped with nuts 14 , so as to lock the steel bars 11 .

[0026] Furthermore, the pressing plate 13 is an arc-shaped plate structure, and the inner side wall is in contact with the outer wall of the rod body of the tire frame, so that the pressing plate 13 can press and fix the connection between the longitudinal rod 2, the cross rod 3 and the vertical rod 8 of the tire frame.

[0027] Furthermore, the reinforcing hoops 5 are arranged at equal intervals from top to bottom to ensure uniform tightening effect on the sides.

[0028] Furthermore, the lower positioning ribs 6 are arranged at equal intervals in the horizontal direction to ensure uniform tightening of the bottom.

[0029] Furthermore, the longitudinal rod 2 is welded end to end to form different lengths, which can be freely adjusted according to the length of different types of anti-slip piles, and at the same time serve as a support system for the steel cage before the installation of the stirrups and the lower positioning main reinforcement, and can be recycled after being dismantled later. The cross bar 3 is welded end to end to form different lengths, which can be freely adjusted according to the width of different types of anti-slip piles, and at the same time serve as a support system for the steel cage before the installation of the stirrups and the lower positioning main reinforcement, and can be recycled after being dismantled later. The scissors struts 4 strengthen the overall stability of the tire frame, ensure that the movable tire frame is not damaged during the processing of the steel cage, and can be recycled after being dismantled later. The reinforcing hoop 5 is the skeleton of the upper main reinforcement and the lower positioning reinforcement 6, which enhances the overall stability of the steel cage later. The lower positioning reinforcement is for positioning and temporary support during the installation of the stirrups, and can be recycled after being dismantled later.

[0030] The movable tire frame for processing anti-sliding pile reinforcement cage of the utility model is used in the following steps:

[0031] 1. Locking mouth and retaining wall construction: The locking mouth and retaining wall are made of reinforced concrete. To ensure the net cross-sectional size of the anti-slip pile, the inner edge size of the locking mouth and retaining wall should be 10cm larger than the size shown in the above figure on each side.

[0032] 2. Drilling: The drilling is done by rotary drilling machine in five steps. The local insufficient areas are trimmed after drilling. To ensure that the drill bit does not deviate during the drilling process, the soil under the drill bit should be in a symmetrical state. The drilling method is to drill the four corners first and then the middle.

[0033] 3. Hole cleaning: After drilling to the designed elevation, check the pile hole size, hole depth and verticality in time, and clean the sediment in the hole in time to ensure that the sediment thickness is within the range specified in the specifications.

[0034] 4. Fabrication and installation of steel cage: The steel cage is processed by the mobile tire frame as a whole, and after the processing is completed, the overall hoisting and hole-entering construction technology is adopted. The longitudinal spacing between the horizontal bars of the mobile tire frame is 3m. To ensure stability, scissor braces are added between the longitudinal directions, and the fasteners can be freely disassembled. The main process of the mobile tire frame as a whole to process the steel cage: First, assemble the connecting fasteners 1, longitudinal bars 2, horizontal bars 3, vertical bars 8 and scissor braces 4 according to the size of the anti-sliding piles. Secondly, use the stiffening hoop 5 to install the top main reinforcement and the lower longitudinal positioning steel bar 6 to position the overall frame. Thirdly, install the stirrups and the main reinforcement at the four corners of the lower part of the stirrups, and remove the mobile tire frame. Finally, install the remaining main reinforcements at the lower part, and the steel cage is processed. The sequence is strictly controlled during the process. All the lower main reinforcements cannot be installed before the stirrups are installed, otherwise it will make the installation of the stirrups extremely difficult and the efficiency is extremely low.

[0035] Considering that the integral steel cage is difficult to transport, the steel cage should be processed into semi-finished products at the steel processing site and transported to the construction site for overall installation. The overall hoisting is carried out by two cranes, one main crane and one auxiliary crane.

[0036] The movable tire frame can adapt to different sizes of anti-slip piles at any time by adjusting the fasteners and the length of the longitudinal and transverse rods, and has a high reuse rate. Even if the components do not meet the use standards due to wear during use, they can be recycled to the manufacturer for reprocessing and reuse, without generating any waste, which has great environmental benefits.

[0037] Using a movable tire frame to tie a steel cage, 6 workers are expected to need 1.5 days to tie a steel cage. There are two other ways to tie a steel cage without using a movable tire frame: ① Construction workers need to enter the pile hole to tie, and the hole wall of the rotary hole has no protective wall, which is inefficient and unsafe; ② Using a fixed tire frame, because the diameter of the stirrup is 16mm, it is difficult to insert, and 6 workers are expected to need 6 days to tie a steel cage, which is extremely inefficient and will destroy the linearity of the steel cage, affecting the hoisting and use performance of the steel cage. Therefore, using a movable tire frame to process the steel cage has great economic benefits.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
