Abstract
Description
Technical Field
[0001] The utility model belongs to a special tool and is a steel section inner insertion positioning device for a TRD construction method wall. Background Art
[0002] like Figure 1 As shown, the TRD construction method wall 2 is a cement soil mixing continuous wall of equal thickness. The TRD construction method pile driver is used to insert a chain saw-type cutting tool into the foundation, dig to the designed depth, and then cut the soil horizontally. At the same time, it is necessary to inject excavation fluid, then withdraw to the origin, inject solidifying fluid, mix with the original soil, and continue to dig horizontally, mix, and advance horizontally to form a high-quality cement soil underground continuous wall, and then insert the steel 1. When making it, first measure and release the axis of the cement soil mixing wall and sprinkle white lime for positioning, then carry out the equal thickness cement soil mixing wall construction, and measure the steel insertion position in the completed part, sprinkle white lime for positioning, and then insert the steel. The grab bucket of the plate inserter grabs the steel and slowly inserts it into the newly formed solid wall section at the predetermined point. However, the position of the steel is basically unlimited by the white lime positioning, and the accuracy of the steel is low, which affects the construction quality. Summary of the invention
[0003] The utility model aims to overcome the shortcoming that the position of the inserted steel sections in the existing cement soil mixing wall with equal thickness is only positioned by lime, resulting in unstable construction quality, and to provide a steel section internal insertion positioning device for TRD construction method walls that can easily position and limit, which is conducive to improving construction quality.
[0004] The technical solution adopted by the utility model is: a steel section insertion positioning device for a TRD construction method wall, the key point of which is that the steel section insertion positioning device is a rigid flat plate, the surface of which is at least larger than the outer contour of a steel section cross section, and is provided with a steel section insertion port adapted to the outer contour of the steel section cross section so that the steel section can pass through.
[0005] The utility model utilizes a flat plate made of rigid material and fixes it on the ground, positions the inserted steel section through the steel section insertion opening, and uses rigid positioning points to replace lime positioning, which can not only position but also limit, thereby improving construction quality.
[0006] Furthermore, the flat plate is rectangular, and its length direction is the arrangement direction of the steel sections in the TRD method wall. It has a corresponding plurality of steel section insertion openings according to the arrangement of the steel sections in the TRD method wall, and the center distance between two adjacent steel section insertion openings is equal to the center distance between two adjacent steel sections.
[0007] The distance between the center point of the steel insertion openings at both ends of the steel insertion positioning device and the edge of the steel insertion positioning device is 0.5 times the length of the center distance between two adjacent steel sections. This facilitates the connection and use of multiple steel insertion positioning devices. A flat plate can also have multiple steel insertion openings to position adjacent multiple inserted steel sections, and once the flat plate is positioned for the first time, multiple flat plates can be spliced without the need for further positioning of the flat plate.
[0008] The length and width of the steel section insertion opening are respectively 5-25 mm larger than the corresponding position of the steel section.
[0009] The flat plate is rectangular, and its length direction is the arrangement direction of the medium-shaped steel in the TRD construction method wall. Tenons and mortises are respectively arranged on both sides of its width direction for splicing adjacent flat plates.
[0010] Weight-reducing holes are arranged around the steel insertion opening. Weight-reducing holes of different shapes or sizes from the steel insertion opening are arranged on the flat plate. When the weight of the selected steel plate is heavy enough, it can be fixed by the weight of the steel insertion positioning device itself. The steel plate is heavy, so the size of a single steel plate is small, and only one steel insertion opening is arranged. Multiple long strip weight-reducing holes are arranged on both sides of the steel insertion opening, and the steel plate is fixed to the ground by its own weight.
[0011] The flat plate is a mesh made of welded steel bars. The mesh made of welded steel bars is light in weight and easy to carry while ensuring strength. A single steel mesh is large in size and can be provided with multiple steel insertion ports, using the mesh holes in the mesh as fixing holes.
[0012] There is a border line painted with eye-catching color paint on the outer edge of the steel insertion port on the flat surface, so that the plate inserter operator can better identify the steel insertion port.
[0013] The width of the flat plate is 2-3.5 times the thickness of the TRD construction wall. In this way, the flat plate is like a cover plate located on the surface of the TRD construction wall and can be used as a stepping platform for workers.
[0014] The utility model has a simple structure, is easy to make, has a limit function, uses the steel insertion port in the rigid steel insertion positioning device to replace the white lime positioning, and the position of the inserted steel is more accurate, thereby improving the construction quality. Through the connection of multiple plates, it can be positioned continuously, and there is no need to measure the insertion position of each steel. The frame line painted with eye-catching color paint allows the plate inserter operator to better identify the steel insertion port, which is conducive to speeding up the construction progress. The rigid steel insertion marking device has the functions of a worker's stepping platform and a correction steel insertion point, which is convenient for the operator to work.

[0023] The present invention is described in detail below in conjunction with the drawings so that those skilled in the art can better understand the present invention.
[0024] like Figure 1 As shown, it is a TRD construction method wall 2, and the bottom inserted steel 1 used therein is as follows Figure 2 H-beam shown.
[0025] Embodiment 1, as Figure 3 As shown, a steel section insertion positioning device for a TRD construction method wall, the flat plate 3 is made of a steel plate. Since the steel plate is heavy, for the convenience of transportation, its length is equal to the center distance between two adjacent steel sections, and its width is 2-3.5 times the thickness of the TRD construction method wall. In this way, the flat plate is like a cover plate located on the surface of the TRD construction method wall, and can be used as a stepping platform for workers. For the convenience of transportation, a plurality of long strip-shaped weight-reducing holes 6 are provided on the workers' stepping platform. The weight-reducing holes reduce the weight of the steel plate and increase the friction of the workers' feet to prevent falls. A steel section insertion opening 5 adapted to the outer contour of the cross section of the steel section is opened in the middle, and the steel section insertion opening is similar in shape to the outer contour of the inserted steel section. Making the steel section insertion opening in a shape similar to the outer contour of the steel section does not affect the positioning and limiting of the steel section, and can also facilitate production. In view of the fact that the steel section used in the current TRD construction method wall is H-shaped steel, this example sets the steel section insertion opening to be rectangular, which is convenient for cutting or punching.
[0026] The length and width of the steel insertion opening are 5-25mm larger than the two-way flange B and web H (including the thickness of the two-way flanges at both ends) of the steel, respectively. In this example, the two sides are 20mm larger. A tenon 31 is provided on one side and a mortise 32 is provided on the other side along the longitudinal direction of the TRD construction method wall, and they are spliced in a concave and convex manner. Figure 4 As shown, the flat plate is rectangular, and the length direction is the arrangement direction of the steel in the TRD construction method wall. Tenons and mortises are respectively arranged on both sides of the width direction for the splicing of adjacent flat plates. According to the arrangement of the steel in the TRD construction method wall, several steel plates are spliced so that they have corresponding multiple steel insertion ports, and the center distance between two adjacent steel insertion ports is equal to the center distance between two adjacent steel. As long as the first steel plate is positioned for the first time, the subsequent steel plates can be spliced using their concave and convex methods. The steel plate is heavy and does not require fixings. It can be fixed by its own weight, especially after multiple steel plates are spliced by tenons and mortises, it is more secure. There is a frame line 7 painted with eye-catching color paint on the outer edge of the steel insertion port on the surface of the flat plate. It enables the plate inserter operator to better identify the steel insertion port.
[0027] The steel plate may also be replaced by a material that is strong, rigid but lighter, such as aluminum or engineering plastics.
[0028] Embodiment 2, as Figure 5-7 As shown, the flat plate is a mesh welded by steel bars, and the grid formed by interval welding becomes a natural weight-reducing hole 6. On the basis of ensuring strength, it is light in weight and easy to carry. The mesh holes in the mesh are used as fixing holes, and no weight-reducing holes are required. A single flat plate is provided with multiple steel section insertion openings 7, 5 of which are shown in the figure. The entire area is 4.5 meters × 2.4 meters. The center distance between two adjacent steel section insertion openings is equal to the center distance between two adjacent steel sections. The spacing between the steel section insertion openings on both sides and the side is 0.5 of the center distance between two adjacent steel sections, which is convenient for splicing. The corner points around the mesh are fixed with U-shaped clips 8, and the rest of the undescribed parts are the same as those in Example 1.
