Description

Technical Field

[0001] The invention relates to the field of building construction, in particular to a three-dimensional space steel mesh manufacturing frame, a manufacturing structure and a construction method. Background Art

[0002] At present, in the production of rockery steel mesh, the steel bars are shaped by the steel bending equipment and then directly delivered to the steel mesh welding process for direct welding. However, when the steel mesh is welded and delivered to the site for installation, how to ensure the fit of the adjacent steel mesh edge bars and the accuracy of the steel mesh shape becomes a problem. The error in the shape of each steel mesh will directly affect the final shape of the entire rockery. When the adjacent steel mesh edge bars do not match, workers need to use manual straightening tools to manually correct them during installation, which is time-consuming and labor-intensive. In addition, the steel mesh installation is done at high altitudes, and workers face greater safety risks when correcting them. Summary of the invention

[0003] The purpose of the present invention is to provide a three-dimensional steel mesh manufacturing frame, manufacturing structure and construction method, to solve the problem that the accuracy of special-shaped steel bars cannot be checked after bending, to solve the problem that it is difficult to accurately position and fix the special-shaped steel bars when they are combined into three-dimensional steel meshes, to solve the problem that the accuracy of the three-dimensional steel mesh modeling is low, and thus the degree of fit between the side bars of adjacent three-dimensional steel meshes is low, and at the same time to solve the problem that manual correction is required during installation due to the mismatch of the side bars of adjacent three-dimensional steel meshes, which is time-consuming, labor-intensive and has high safety risks.

[0004] To achieve the above object, the present invention adopts the following technical solution:

[0005] The three-dimensional steel mesh manufacturing frame includes an external frame of a rectangular three-dimensional structure, the rear part of the external frame is connected to a vertically arranged rectangular partition frame, the part of the external frame located in front of the partition frame is a precise positioning area, and the part of the external frame located behind the partition frame is a detection area.

[0006] The left frame of the precise positioning area is filled with left matrix grids, the right frame is filled with right matrix grids, the top frame is filled with top matrix grids, the bottom frame is filled with bottom matrix grids, and the partition frame is filled with partition frame matrix grids.

[0007] The left side, right side, top surface, bottom surface, and partition frame matrix grids are all composed of horizontally penetrating, evenly spaced horizontal bars and vertically penetrating, evenly spaced vertical bars, and the spacing between the horizontal bars is the same as the spacing between the vertical bars.

[0008] Furthermore, a first support rod that is horizontally spaced apart is connected between a pair of vertical rods of the partition frame, and a first clamp is fixedly connected to the first support rod at intervals.

[0009] Furthermore, a second support rod which is arranged horizontally and spaced apart and corresponds to the first support rod is connected between a pair of vertical rods on the rear side of the external frame, and a second clamp which is arranged horizontally and spaced apart and corresponds to the first clamp is fixedly connected to the second support rod.

[0010] Furthermore, a detection rod is movably connected between the corresponding first clamping member and the second clamping member, and the front part of the detection rod extends into the precise positioning area.

[0011] Further, the first clamping member includes a U-shaped body, a jacking bolt with vertical threads passing through the horizontal limb of the U-shaped body, and a locking nut with threads sleeved on the jacking bolt;

[0012] The structure of the second clamp is the same as that of the first clamp.

[0013] Furthermore, two ends of the vertical limb of the U-shaped body are fixedly connected to the top surface of the first support rod.

[0014] According to the manufacturing structure of the three-dimensional steel mesh manufacturing frame, it includes a three-dimensional steel mesh manufacturing frame and a steel mesh connected in the three-dimensional steel mesh manufacturing frame by spot welding; the steel mesh includes vertical special-shaped steel bars arranged at intervals and horizontal special-shaped steel bars arranged at intervals and spot-welded to the vertical special-shaped steel bars; a vertical special-shaped steel bar located on the far left is spot-welded to the left matrix grid, and a vertical special-shaped steel bar located on the far right is spot-welded to the right matrix grid; the front end of the detection rod is supported on the middle of the vertical special-shaped steel bars and the horizontal special-shaped steel bars.

[0015] According to the construction method of the manufacturing structure, the steps are:

[0016] Step 1: define a three-dimensional rectangular coordinate system in the precise positioning area, specifically, define the left bottom corner point of the partition frame as the origin, define the bottom horizontal bar of the partition frame as the X-axis, define the bottom horizontal bar of the left frame as the Y-axis, and define the left vertical bar of the partition frame as the Z-axis. Each horizontal bar and each vertical bar of the matrix grid in the precise positioning area represents a coordinate point.

[0017] Step 2: According to the design coordinate points on the drawing, spot weld the leftmost vertical special-shaped steel bar to the left matrix grid (i.e., YOZ plane) in the precise positioning area.

[0018] Step three, according to the design coordinate points on the drawing, spot weld one end of the transverse special-shaped steel bar to the vertical special-shaped steel bar on the far left in the precise positioning area, and spot weld the other end of the transverse special-shaped steel bar to the matrix grid on the right.

[0019] Step 4: Check the middle position of the welded transverse special-shaped steel bars by using the detection rod: The detection rods are spaced in the middle area of ​​the three-dimensional steel mesh frame, and are fixed in the X-axis and Z-axis coordinates. According to the Z-axis coordinate of the transverse special-shaped steel bar point that is the same as the X-axis and Z-axis coordinates of the detection rod on the drawing, adjust the length of the detection rod. At this time, the position of the front end of the detection rod is the standard position of the corresponding transverse special-shaped steel bar. Then, adjust the transverse special-shaped steel bar according to the position of the standard position, and check the middle position of the transverse special-shaped steel bar.

[0020] Step 5. According to the design coordinate points on the drawing, the vertical special-shaped steel bars are spot welded to the transverse special-shaped steel bars in the precise positioning area in sequence. The vertical special-shaped steel bar on the far right is spot welded to the matrix grid on the right to form a three-dimensional steel mesh.

[0021] Step six, check the middle point of the three-dimensional steel mesh by using the detection rod: the detection rods are spaced in the middle area of ​​the three-dimensional steel mesh manufacturing frame, and are fixed in the X-axis and Z-axis coordinates. According to the Z-axis coordinate of the steel mesh point on the drawing that is the same as the X-axis and Z-axis coordinates of the detection rod, adjust the length of the detection rod. At this time, the position of the front end of the detection rod is the standard point of the corresponding steel mesh. Then adjust the steel mesh according to the position of the standard point, and check the middle point of the steel mesh so that it can accurately meet the use requirements of the drawing.

[0022] Step seven: Use spot welding to fix the positioned steel bars to complete the production of the three-dimensional steel mesh.

[0023] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0024] 1. The three-dimensional steel mesh manufacturing frame of the present invention has matrix grids in the left frame, right frame, top frame, bottom frame and partition frame of the precise positioning area to form a three-dimensional rectangular coordinate system that can be accurately positioned. The corresponding points can be quickly found in the precise positioning area according to the design points on the drawings to accurately spot weld and connect the steel mesh. The rockery with various shapes can be accurately positioned, and the positioning is accurate, which can fully demonstrate the design requirements for the shape of the rockery mesh. Therefore, before the steel mesh is welded, the accuracy and fit of the adjacent side bars of the rockery steel mesh can be guaranteed, and the steel mesh production can be separated from the on-site implementation, which is convenient to operate and easy to construct, greatly increasing the construction progress and saving human resources.

[0025] 2. The three-dimensional steel mesh manufacturing frame of the present invention is provided with a detection area. The point position in the middle of the steel mesh is checked by adjusting the length of the detection rod according to the positioning on the drawing, so as to ensure the accuracy of the spot welding connection of the cross-connection points of the horizontal and vertical special-shaped steel bars in the middle of the steel mesh, solve the problem of difficulty in checking the connection accuracy after the special-shaped steel bars are bent, and solve the problem of difficulty in accurately positioning and fixing when the special-shaped steel bars are combined into a three-dimensional steel mesh.
