Description

Technical Field

[0001] This utility model relates to a loading hole module forming technology, and in particular to a reaction wall loading hole unit block manufacturing mold and loading hole unit block. Background Technology

[0002] Large reaction walls typically contain thousands of loading holes, each composed of pre-embedded steel pipes (sometimes referred to as loading holes in the industry). High precision is required for the verticality of these loading holes along their longitudinal and transverse axes, the accuracy of the hole spacing, and the flatness of the pipe ends on the outer surface of the wall. However, traditionally, these pre-embedded steel pipes are installed one by one into the reaction wall, with measurements taken and fixed sequentially. This method suffers from two problems: first, the positioning errors of the pre-embedded steel pipes accumulate, making it difficult to achieve the required accuracy for all loading holes on the reaction wall, resulting in low overall structural precision; second, the installation speed of the pre-embedded steel pipes is slow, and construction or correction is difficult. To address this, current technology proposes multiple loading holes, each composed of several pre-embedded steel pipes forming a unit block. These unit blocks are then assembled into a large reaction wall loading hole system, aiming to reduce accumulated errors and improve the overall structural precision.

[0003] Chinese patent CN 117552554 B discloses a "Construction Structure and Construction Method for Combined Installation of Loading Hole Modules for Reaction Walls". This technology "determines the installation position of the first loading hole (3) using measuring equipment, welds and fixes the X-axis support rod (11) and Y-axis support rod (12), and fixes the first loading hole (3) onto the X-axis support rod (11) and Y-axis support rod (12)". Chinese patent CN 109916617 B discloses a "Method for Manufacturing a Reaction Wall and a Loading Hole Unit Adjustment Device". This device first "fabricates a loading hole unit, which includes a loading hole welding bracket, on which multiple arrayed loading holes are welded and fixed". Chinese patent CN 115506513 A discloses a "Prefabricated Loading Hole Pipe Fittings for Reaction Wall Construction and a Reaction Wall Construction Method". In this technology, the reaction wall is equipped with a channel steel positioning frame, which is welded from several longitudinal and transverse channel steels to position the steel pipe (loading hole). The steel pipe is welded and fixed to the longitudinal channel steel on one side and to the transverse channel steel on the other side by a positioning steel plate.

[0004] As can be seen from the above description, the core of the aforementioned patented technology is still to weld the loading holes (pre-embedded steel pipes) one by one onto a pre-made bracket based on the position of the first loading hole (pre-embedded steel pipe), thus forming a loading hole unit. In this type of loading hole unit, the pre-embedded steel pipes on the bracket are still welded one by one in sequence, and the cumulative error of the loading holes still exists. Therefore, the overall accuracy of the reaction wall loading holes is still difficult to meet the standard. Utility Model Content

[0005] One objective of this invention is to overcome the problems of existing technologies where pre-embedded steel pipes in unit loading holes are still welded to the support one by one, resulting in accumulated errors, difficulty in achieving the overall installation quality of reaction wall loading holes, and slow installation speed of pre-embedded steel pipes. This invention provides a method that simultaneously positions and assembles several pre-embedded steel pipes into a mold frame to create a loading hole unit block in one go. The assembly tolerance of each pre-embedded steel pipe in the unit block is independent, unrelated, and without accumulated errors. High-quality assurance is achieved for the perpendicularity of the longitudinal and transverse axes of the arrayed loading holes, the accuracy of the hole spacing, and the flatness on the reaction wall surface. The overall reaction wall loading hole forming speed is fast, the quality is good, and the mold frame can be repeatedly disassembled and reused with a wide range of applications.

[0006] The purpose of this utility model is achievable. The mold frame for fabricating the reaction wall loading hole unit block of this utility model includes four horizontally arranged transverse H-beams at equal intervals and a rectangular mold base consisting of six horizontally welded longitudinal H-beams at equal intervals on top of the transverse H-beams. The characteristic of this reaction wall loading hole unit block mold frame is that: several pre-embedded steel pipe piles are positioned and welded in a longitudinal and transverse array on the upper surface of each of the six longitudinal H-beams; three columns are welded to the upper surface of each of the four transverse H-beams; the columns at both ends of the four transverse H-beams are symmetrically positioned; the four middle columns are all located at the midpoint of the length of the transverse H-beams; ten columns surrounding the four transverse H-beams form a rectangular support column; the two middle columns form a central support column; a support plate is provided at the upper end of the rectangular support column and the central support column; positioning pins are provided on the support plate; two enclosing channel steels are horizontally welded to the outer side of each of the four sides of the rectangular support column; the inner piles, rectangular support columns, central support columns, and... The surrounding channel steel, support plates, and positioning pins constitute a quadrangular prism of the mold frame. All the support plates together support a shaped steel plate. A channel steel reinforcing frame is welded onto the shaped steel plate. The shaped steel plate and the channel steel reinforcing frame are provided with positioning pin holes at the positions aligned with the positioning pins. The shaped steel plate and the channel steel reinforcing frame are installed on the quadrangular prism of the mold frame through the positioning pin holes and positioning pins. Several pre-embedded steel pipe insertion holes and construction holes are arranged in a longitudinal and transverse array on the shaped steel plate. The shaped steel plate with positioning pin holes, pre-embedded steel pipe insertion holes, and construction holes, as well as the channel steel reinforcing frame welded to the shaped steel plate, constitute the mold frame assembly cover plate. The mold frame base, the quadrangular prism of the mold frame, and the mold frame assembly cover plate constitute the loading hole unit block mold frame.

[0007] The present invention relates to a reaction wall loading hole unit block manufacturing mold frame, wherein the number of pre-embedded steel pipe insertion holes is equal to the number of internal piles, and the array configuration of the pre-embedded steel pipe insertion holes and the array configuration of the internal piles form an upper and lower symmetrical structure.

[0008] In the formwork for manufacturing reaction wall loading hole unit blocks of the present utility model, the inner inserting pile is circular, the outer diameter of the inner inserting pile is 1 mm smaller than the inner diameter of the embedded steel pipe, and the inner diameter of the embedded steel pipe insertion hole on the shaping steel plate and the channel steel reinforcing frame is 1 mm larger than the outer diameter of the embedded steel pipe.

[0009] In the formwork for manufacturing reaction wall loading hole unit blocks of the present utility model, the channel steel reinforcing frame welded on the shaping steel plate on the supporting plate is in a shape of Chinese character "mu", and the outer edge dimension of the channel steel reinforcing frame in the shape of Chinese character "mu" is equal to the outer edge dimension of the shaping steel plate.

[0010] In the formwork for manufacturing reaction wall loading hole unit blocks of the present utility model, the supporting plate is in a circular ring shape, the supporting plate is welded on the upper end of the upright post at equal height through the inner diameter of the circular ring, and the positioning inserting column is located at the center of the circle above the supporting plate.

[0011] Another object of the present utility model is to provide a loading hole unit block manufactured by the formwork for manufacturing reaction wall loading hole unit blocks. The loading hole unit block of the present utility model is characterized in that: the upper parts of a plurality of embedded steel pipes with equal specifications and lengths are inserted into the embedded steel pipe insertion holes of the formwork, the bottoms are inserted on the inner inserting piles, all the embedded steel pipes are arranged in a transverse and longitudinal array at equal intervals, a plurality of transversely arranged embedded steel pipes are welded and fixed into one row by one transverse channel steel through construction holes, a plurality of longitudinally arranged embedded steel pipes are welded and fixed into one column by one longitudinal channel steel through construction holes, and all the embedded steel pipes in the formwork are welded and fixed together through a plurality of transverse channel steels and a plurality of longitudinal channel steels to form a loading hole unit block with a plurality of rows and columns.

[0012] In the loading hole unit block of the present utility model, the embedded steel pipes are independently arranged on the longitudinal H-beam, and the positioning positions and assembly tolerances of each other do not affect each other.

[0013] In the loading hole unit block of the present utility model, the embedded steel pipes are connected with the embedded steel pipe insertion holes and the inner inserting piles in a movable fit structure.

[0014] In the loading hole unit block of the present utility model, a plurality of loading hole unit blocks are assembled to form an integral reaction wall loading hole.

[0015] The difference between this utility model's reaction wall loading hole unit block fabrication mold frame and existing technology lies in that the mold frame for fabricating the reaction wall loading hole unit block of this utility model includes four transverse H-beams welded to six longitudinal H-beams. Several pre-embedded steel pipes are positioned and welded in a longitudinal and transverse array on the upper surface of each longitudinal H-beam. Three columns are symmetrically welded to each transverse H-beam. Each side of the rectangular columns located on the outer side of the H-beams is welded with enclosing channel steel. All columns are welded with support plates containing positioning inserts. These support plates collectively support a shaped steel plate with several pre-embedded steel pipe insertion holes, positioning holes, and construction holes, and a channel steel reinforcing frame welded to it. The positioning holes, positioning inserts, and shaped steel plate combined on the columns constitute the loading hole unit block mold frame. In the loading hole unit block formwork, several pre-embedded steel pipes of equal specifications and lengths are inserted into pre-embedded steel pipe insertion holes at the top and into inner piles at the bottom. Several pre-embedded steel pipes arranged in a horizontal row are welded together to form a row through construction holes by a horizontal channel steel, and several pre-embedded steel pipes arranged in a vertical row are welded together to form a column through construction holes by a vertical channel steel. All the pre-embedded steel pipes in the formwork are welded and fixed together by several horizontal and several vertical channel steels to form a loading hole unit block with several rows and columns. The assembly tolerance of the pre-embedded steel pipes in the unit block exists independently, with no accumulated error, resulting in high loading hole accuracy. The assembled overall reaction wall loading hole forming speed is fast and the quality is good. This utility model formwork can be repeatedly disassembled and reused, and has a wide range of applications.

The positioning ring 3 is used for fixing the lower part of the embedded steel pipe 12. Three upright posts 4 are welded on the upper surface of each of the four transverse H-beams 1. The positions of the upright posts 4 at both ends of the four transverse H-beams 1 are symmetrical, and the four middle upright posts 4 are all located at the midpoint of the length of the transverse H-beams 1.

On the outer side of each of the four surfaces of the rectangular support column, two enclosing channel steels 5 are horizontally welded. The inner inserting piles 3, the rectangular support columns, the middle support column 41, the enclosing channel steels 5, the supporting plates 6 and the positioning inserting columns 61 form a quadrangular prism body of the formwork. All the supporting plates 6 jointly support a shaping steel plate 7. A channel steel reinforcing frame 8 is welded on the shaping steel plate 7, and the channel steel reinforcing frame 8 is a reinforcing member for preventing the deformation of the shaping steel plate 7. The shaping steel plate 7 and the channel steel reinforcing frame 8 are both provided with positioning insertion holes 9 for the positioning inserting columns 61 at positions aligned with the positioning inserting columns 61. The shaping steel plate 7 and the channel steel reinforcing frame 8 are installed on the quadrangular prism body of the formwork through the positioning insertion holes 9 and the positioning inserting columns 61. A plurality of embedded steel pipe insertion holes 10 and construction holes 11 are positioned and arranged on the shaping steel plate 7 in a matrix arrangement in both longitudinal and transverse directions.

The formwork base, the quadrangular prism body of the formwork and the assembled formwork cover plate form a combined loading hole unit block formwork.

[0027] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the number of the embedded steel pipe insertion holes 10 is equal to the number of the inner inserting piles 3, and the array positions of the embedded steel pipe insertion holes 10 and the array positions of the inner inserting piles 3 form a vertically symmetrical structure.

Several pre-embedded steel pipes 12 arranged in a transverse row are welded and fixed into a row by a transverse channel steel 13 through construction holes 11; several pre-embedded steel pipes 12 arranged in a longitudinal row are welded and fixed into a column by a longitudinal channel steel 14 through construction holes 11. All the pre-embedded steel pipes 12 within the mold frame are welded and fixed together by several transverse channel steels 13 and several longitudinal channel steels 14 to form a loading hole unit block with several rows and columns. The pre-embedded steel pipes 12 are independently set on the longitudinal H-beams 2, and their positioning and assembly tolerances do not affect each other. The loading hole forming accuracy is high.

[0033] like Figure 8 As shown, according to the design requirements, several loading hole unit blocks are assembled together to form the loading hole of the overall reaction wall.

[0035] The inner pile 3, positioning hole 9, pre-embedded steel pipe hole 10, and construction hole 11 are all made using a laser cutting machine to ensure their accuracy. The inner pile 3, positioning hole 9, and pre-embedded steel pipe hole 10 can accurately and quickly position and assemble the loading hole.
