Description

Technical Field

[0001] The utility model relates to the technical field of steel mesh fixing tooling, in particular to a thin-walled hollow multi-curved plain concrete arch steel mesh fixing tooling. Background Art

[0002] Thin-walled hollow multi-curved exposed concrete arches are generally designed in a ring shape and are set around the main body of the building, mainly for decoration. The circumference of this concrete structure is relatively long, and it is usually divided into several arc-shaped segments for segmented casting. The span of a single segment can be as long as tens of meters.

[0003] In order to improve the positioning accuracy of the steel mesh in the shaped arch, a construction method of first building an inner mold and then laying the steel mesh with the inner mold as the reference layer is adopted. Compared with the traditional steel mesh construction method of first building an outer mold and then using the inner wall of the outer mold as the reference layer, most of the steel bars in the steel mesh are in a suspended state during the specific construction process. Therefore, a corresponding fixing device needs to be set between the steel mesh and the inner mold to provide stable support for the steel mesh to prevent the steel mesh from bending and deforming due to its own deflection and gravity when it is laid over a large span. At the same time, it also prevents the steel mesh of a large span from overturning, thereby ensuring the accuracy of the steel mesh positioning and the stability of the steel skeleton formed by the multi-layer steel mesh.

[0004] To this end, the present application specifically proposes a thin-walled hollow multi-curved plain concrete arch steel mesh fixing tool to solve the above technical problems. Utility Model Content

[0005] The main purpose of the utility model is to solve the above-mentioned deficiencies and provide a thin-walled hollow multi-curved plain concrete arch steel mesh fixing tool to provide stable support for the steel mesh to prevent its bending and deformation from affecting the positioning accuracy.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A fixing tool for a thin-walled hollow multi-curved plain concrete arch steel mesh comprises: a threaded steel bar, one end of which is fixedly arranged on a steel beam, and the other end of which passes through an extruded plate and extends to the outside of the extruded plate; a first positioning component, which is passed through the threaded steel bar and abuts against the extruded plate, and is used to position the steel bars in a first layer of steel mesh, and the first positioning component is threadedly connected to the threaded steel bar; a second positioning component, which is passed through the threaded steel bar and threadedly connected to the threaded steel bar, and is used to position the steel bars in a second layer of steel mesh.

[0008] Furthermore, the first positioning assembly includes a ball head threadedly connected and inserted into the threaded steel bar, a top block rotatably arranged on the outer wall of the ball head, and a hexagonal block fixedly arranged on one end of the ball head extending out of the top block.

[0009] Furthermore, the top block includes a right block for abutting against the extruded plate and a left block fixedly arranged on one side of the right block, and the right block and the left block are connected by screws.

[0010] Furthermore, a conical hole is provided on a side of the right block abutting against the extruded plate.

[0011] Furthermore, a threaded hole is provided on the left block, an adjusting screw is arranged in the threaded hole, and the adjusting screw passes through the left block and abuts against the ball head.

[0012] Furthermore, the positioning block is provided with a positioning groove for clamping the steel bar.

[0013] Furthermore, two connecting rod assemblies are symmetrically arranged between the first positioning assembly and the second positioning assembly, and two ends of the connecting rod assembly are respectively hinged to the first positioning assembly and the second positioning assembly.

[0014] Furthermore, the connecting rod assembly includes a rod sleeve with one end hinged to the first positioning assembly and an insertion rod with one end hinged to the second positioning assembly and the other end inserted into the rod sleeve, a positioning hole is provided on the insertion rod, and long sliding grooves are provided on both sides of the rod sleeve.

DETAILED DESCRIPTION

[0032] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] like Figure 1-12 As shown, the utility model provides a thin-walled cavity multi-curved plain concrete arch steel mesh fixing tool, comprising:

[0034] The threaded steel bar 1 has one end fixed on the steel beam 2 and the other end passing through the extruded plate 3 and extending to the outside of the extruded plate 3;

[0035] The first positioning component 4 is passed through the threaded steel bar 1 and abuts against the extruded plate 3, and is used to position the steel bars in the first layer of the steel mesh. The first positioning component 4 is threadedly connected to the threaded steel bar 1;

[0036] The second positioning component 5 is passed through the threaded steel bar 1 and is threadedly connected to the threaded steel bar 1, and is used for positioning the steel bars in the second layer of the steel mesh.

[0037] like Figure 5 and Figure 6 As shown, before laying the steel mesh, first fix one end of the threaded steel bar 1 on the steel beam 2, then pass the first positioning component 4 and the second positioning component 5 through the portion of the threaded steel bar 1 passing through the extruded board 3, and make the first positioning component 4 close to the extruded board 3. Since the extruded board 3 is used as the inner mold of the thin-walled cavity arch, the first positioning component 4 can also serve as a spacer between the first layer of steel mesh and the extruded board 3 to ensure that there is enough protective layer between the first layer of steel mesh and the extruded board 3 after pouring. During the process of laying the first layer of steel mesh, the steel bars in the first layer of steel mesh can be tied with the threaded steel bar 1 as a fulcrum to ensure the effective fixation of the steel mesh. At the same time, the steel bars are positioned and shaped by multiple first positioning components 4 in the same cross-section of the steel beam 2 so that the shape of the steel bars can be parallel to the extruded board 3. Similarly, the second layer of steel mesh also uses the threaded steel bar 1 as a fixed binding point, and with the help of the second positioning component 5, the steel bars are positioned and shaped during the laying process of the second layer of steel mesh. At the same time, the second positioning component 5 can also be used as a spacer between the second layer of steel mesh and the outer mold of the thin-walled cavity arch.

[0038] It is worth further explaining that Figure 3 and Figure 5In the figure, only a single steel mesh fixing tool is drawn, which is only used to show its installation position and usage status. In actual construction, multiple fixing tools should be set on the steel beam 2 as needed to fix and position the steel mesh in multiple places. Figure 7 As shown in the figure, a set of steel mesh fixing fixtures are installed and used for a single section of a thin-walled cavity shape arch. In actual construction, in order to ensure the overall stability, anti-overturning and positioning accuracy of the steel mesh, multiple sets of steel mesh fixing fixtures should be evenly spaced on the thin-walled cavity shape arch to evenly cover the entire shape arch.

[0039] In one embodiment, the first positioning assembly 4 includes a ball head 41 threadedly connected and penetrated on the threaded steel bar 1, a top block 42 rotatably arranged on the outer wall of the ball head 41, and a hexagonal block 43 fixedly arranged on the end of the ball head 41 extending out of the top block 42. With such a design, the top block 42 can rotate around the ball head 41, and the hexagonal block 43 can be rotated with a wrench to drive the ball head 41 to move along the threaded steel bar 1 in a direction close to the extruded plate 3, and drive the top block 42 to abut against the extruded plate 3. The top block 42 rotates around the ball head 41 in the process of gradually tightening the extruded plate 3 until it completely fits the outer surface of the extruded plate 3. At this time, continuing to tighten the hexagonal block 43 can make the ball head 41 abut against the top block 42, thereby locking the inclination angle of the top block 42.

[0040] It should be noted that the outer surface of the extruded board 3 is a curved surface, but since the span of the thin-walled cavity arch is relatively large, the surface of the extruded board 3 corresponding to a single top block 42 can be approximately regarded as a plane, so the top block 42 can press against the outer surface of the extruded board 3.

[0041] In one embodiment, the top block 42 includes a right block 421 for abutting against the extruded plate 3 and a left block 422 fixedly arranged on one side of the right block 421, and the right block 421 and the left block 422 are connected by screws. With this design, when installing the ball head 41, the ball head 41 can be first inserted into the left block 422, and then the right block 421 and the left block 422 are locked by screws to ensure the normal installation of the ball head 41.

[0042] In one embodiment, a tapered hole 6 is provided on one side of the right block 421 that abuts against the extruded plate 3. This design prevents the top block 42 from interfering with the threaded steel bar 1 easily during the rotation process around the ball head 41, thereby increasing the rotation angle of the top block 42.

[0043] In one embodiment, a threaded hole is provided on the left block 422, and an adjusting screw 7 is arranged in the threaded hole, and the adjusting screw 7 passes through the left block 422 and abuts against the ball head 41. With this design, the tilt angle of the top block 42 relative to the ball head 41 can be locked by screwing the adjusting screw 7 into the threaded hole and abutting against the ball head 41.

[0044] In one embodiment, a positioning block 8 is fixedly provided on the left block 422, and a positioning groove 9 for clamping a steel bar is provided on the positioning block 8. With such a design, when the first positioning assembly 4 is pressed against the extruded board 3, the positioning block 8 is in a state of being parallel to the extruded board 3, and by clamping the steel bar in the steel mesh in the positioning groove 9, the steel bar can also be parallel to the extruded board 3, thereby realizing the positioning of the steel bar.

[0045] It should be noted that when the first positioning assembly 4 is pressed against the extruded plate 3 , the positioning block 8 is not necessarily in a state parallel to the extruded plate 3 , but the positioning block 8 can be adjusted to be parallel to the extruded plate 3 by rotating the top block 42 .

[0046] In one embodiment, two connecting rod assemblies 10 are symmetrically arranged between the first positioning assembly 4 and the second positioning assembly 5, and the two ends of the connecting rod assembly 10 are respectively hinged to the first positioning assembly 4 and the second positioning assembly 5. With such a design, when the first positioning assembly 4 is pressed against the extruded board 3, the top block 42 in the first positioning assembly 4 rotates, and the top block 42 can drive the second positioning assembly 5 to rotate synchronously through the connecting rod assembly 10, ensuring that the first positioning assembly 4 and the second positioning assembly 5 are always parallel, thereby ensuring that the positioning blocks 8 in the first positioning assembly 4 and the second positioning assembly 5 are always parallel, and finally ensuring that the first layer of steel mesh clamped in the first positioning assembly 4 and the second layer of steel mesh clamped in the second positioning assembly 5 are parallel, and further positioning the steel mesh.

[0047] In one embodiment, the connecting rod assembly 10 includes a rod sleeve 101 hinged to the first positioning assembly 4 at one end and an insertion rod 102 hinged to the second positioning assembly 5 at one end and inserted in the rod sleeve 101 at the other end. The insertion rod 102 is provided with a positioning hole 11, and long strip-shaped slide grooves 12 are provided on both sides of the rod sleeve 101. With such a design, the overall length of the connecting rod assembly 10 can be changed by changing the length of the insertion rod 102 inserted into the rod sleeve 101, thereby changing the spacing between the first positioning assembly 4 and the second positioning assembly 5, and finally changing the spacing between the first layer of steel mesh stuck in the first positioning assembly 4 and the second layer of steel mesh stuck in the second positioning assembly 5, ensuring that the spacing meets the design requirements. The bolt is passed through the positioning hole 11 and the slide groove 12 at the same time and locked, that is, the length of the insertion rod 102 into the rod sleeve 101 is locked.

[0048] In one embodiment, the second positioning assembly 5 has the same structure as the first positioning assembly 4. It should be noted that since the second positioning assembly 5 also serves as a spacer for the second layer of steel mesh, after the steel mesh is laid, the portion of the threaded steel bar 1 that exceeds the second positioning assembly 5 needs to be cut off to ensure that the second positioning assembly 5 can abut against the outer mold of the thin-walled cavity arch.

[0049] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0050] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
