Description

Technical Field

[0001] This utility model relates to the field of steel formwork support technology, and in particular to a steel formwork support for canal construction. Background Technology

[0002] As a vital waterway, the construction quality of the canal's main channel directly affects its navigability and service life. However, current canal main channel construction faces numerous pressing problems. Firstly, the construction environment for canal main channels is complex and varied, often traversing different geological conditions, including soft soil, sand, and rock strata, which places higher demands on construction technology and equipment. Secondly, ensuring construction precision is difficult. Canal main channel construction involves extensive earthwork excavation and concrete pouring; ensuring construction precision and avoiding over-excavation or under-excavation is a major challenge currently facing construction.

[0003] Currently, canal construction mainly relies on formwork support technology, such as wooden formwork and steel formwork. In canal construction, steel formwork (including combined steel formwork and standardized steel formwork) and slipform are the most commonly used formwork types, especially suitable for standardized construction of large and medium-sized projects. For small projects or irregular structures, wooden formwork and plastic formwork serve as supplementary methods, flexibly adapting to site requirements.

[0004] When faced with complex and ever-changing construction environments, wooden formwork is easily affected by humid conditions, leading to problems such as deformation and cracking. Although steel formwork has high strength, it is still difficult to guarantee construction accuracy and stability under certain special geological conditions. Utility Model Content

[0005] The purpose of this invention is to address the problem in the background technology that wooden and steel formwork are difficult to guarantee construction accuracy and stability in complex and ever-changing construction environments, and to propose a steel formwork support for canal construction.

[0006] The technical solution of this utility model is: a steel formwork support for dry canal construction, comprising multiple supporting steel plates, with multiple steel reinforcement frames equidistantly distributed along a straight line between two adjacent supporting steel plates, and transverse and longitudinal steel reinforcement laid on the top of the supporting steel plates, the transverse and longitudinal steel reinforcement being perpendicular to each other;

[0007] The binding mechanism includes a transverse positioning strip and a longitudinal positioning strip. The transverse positioning strip has multiple equidistant inverted positioning notches in the middle, through which the longitudinal reinforcing bar passes. The longitudinal positioning strip has multiple equidistant upright positioning notches in the middle, through which the transverse reinforcing bar passes. A positioning element is provided at the intersection of the transverse and longitudinal positioning strips.

[0008] The positioning component is equipped with an obstruction mechanism.

[0009] Optionally, the length of the upright positioning notch located in the middle of the longitudinal positioning strip is longer than the length of the upright positioning notch at other positions, and the upright positioning notch at this position can accommodate two transverse positioning strips and a steel frame.

[0010] Optionally, the positioning component includes positioning clamps, which have an L-shaped structure. Four positioning clamps are provided, forming a cross-shaped structure. The four positioning clamps clamp the transverse positioning strip, the reinforcing steel frame, and the longitudinal positioning strip.

[0011] Optionally, two adjacent positioning clamps are connected to each other by bolts, and a rotating head is fixedly installed at the end of the bolt.

[0012] Optionally, one end of the bolt connected to the rotating head is rotatably connected to the positioning clamp, and the other end of the bolt is threadedly connected to the positioning clamp.

[0013] Optionally, the obstruction mechanism includes a guide rod that slides horizontally along the diameter of the rotating head, and an elastic ring is fixedly installed at the end of the guide rod, with a rotation obstruction member provided on the outer wall of the elastic ring.

[0014] Optionally, the rotational obstruction includes two protrusions symmetrically distributed on the outer wall of the elastic ring, and an obstruction block is fixedly installed on the outer wall of the positioning clamp, the obstruction block being located on the rotational path of the protrusions.

[0016] Optionally, the reinforcing steel frame adopts a square frame structure, and the interior of the reinforcing steel frame and the four corners are all fixedly connected with supporting reinforcing steel bars by steel wires, and the multiple supporting reinforcing steel bars are parallel to each other.

[0017] Optionally, multiple transverse and longitudinal reinforcing bars are provided, and the multiple transverse and longitudinal reinforcing bars are distributed in a checkerboard pattern.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] 1. This utility model uses transverse and longitudinal positioning strips to position the transverse and longitudinal reinforcing bars, establishing the position of each transverse and longitudinal reinforcing bar. This makes the support of the transverse and longitudinal reinforcing bars on the supporting steel plate more uniform. By rotating the rotating head to turn the bolts, the distance between the positioning clamps at adjacent positions can be adjusted to accommodate transverse and longitudinal positioning strips of different diameters, thereby increasing the clamping force, preventing the transverse and longitudinal reinforcing bars from loosening, and improving construction accuracy and stability.

[0020] 2. This utility model restricts the position of the protrusion by using an obstruction block, so that the guide rod, elastic ring and protrusion cannot rotate. Since the rotating head is connected to the guide rod, the rotating head cannot drive the bolt to rotate. The position of the four positioning clamps cannot be changed, thus avoiding the vibration generated during the processing of the bracket, which would cause the bolt to vibrate and move the positioning clamps, affecting the stability of construction.

[0032] Example 1

[0033] This embodiment proposes a steel formwork support for dry canal construction, such as... Figure 1 and Figure 2 As shown, it is applied to multiple supporting steel plates 1. Multiple steel reinforcement frames 2 are set between two adjacent supporting steel plates 1 and are distributed at equal intervals along a straight line. The top of the supporting steel plate 1 is covered with transverse steel reinforcement 3 and longitudinal steel reinforcement 4. The transverse steel reinforcement 3 and longitudinal steel reinforcement 4 are perpendicular to each other. Multiple transverse steel reinforcement 3 and multiple longitudinal steel reinforcement 4 are set. The multiple transverse steel reinforcement 3 and multiple longitudinal steel reinforcement 4 are distributed in a checkerboard pattern. The distance between the first transverse steel reinforcement 3 and the edge of the supporting steel plate 1 and the edge of the wall is fifty millimeters.

[0034] The reinforcing steel frame 2 adopts a square frame structure. Inside the reinforcing steel frame 2 and near the four corners, there are supporting reinforcing steel bars 7 fixedly connected by steel wires. Multiple supporting reinforcing steel bars 7 are parallel to each other.

[0035] like Figure 3 and Figure 4As shown, a binding mechanism 5 is provided at the top of the reinforcing steel frame 2. The binding mechanism 5 includes a transverse positioning bar 51 and a longitudinal positioning bar 52. The transverse positioning bar 51 has multiple inverted positioning recesses 53 that are evenly distributed in the middle. The longitudinal reinforcing steel bar 4 passes through the inverted positioning recesses 53. The longitudinal positioning bar 52 has multiple upright positioning recesses 54 that are evenly distributed in the middle. The transverse reinforcing steel bar 3 passes through the upright positioning recesses 54. The inverted positioning recesses 53 make the multiple longitudinal reinforcing steel bars 4 evenly distributed, and the upright positioning recesses 54 make the multiple transverse reinforcing steel bars 3 evenly distributed, so that the supporting steel plate 1 is more evenly supported by the transverse reinforcing steel bars 3 and the longitudinal reinforcing steel bars 4.

[0036] The upright positioning notch 54 located in the middle of the longitudinal positioning strip 52 is longer than the upright positioning notches 54 at other positions. The upright positioning notch 54 at this position accommodates two transverse positioning strips 51 and the reinforcing bar frame 2. A positioning element is provided at the intersection of the transverse positioning strips 51 and the longitudinal positioning strips 52. The positioning element fixes the position of the transverse positioning strips 51 and the longitudinal positioning strips 52 to position the transverse reinforcing bar 3 to be supported, so as to prevent the transverse reinforcing bar 3 and the longitudinal reinforcing bar 4 from deviating from their original positions when they are tied.

[0037] The positioning components include positioning clamps 55, which have an L-shaped structure. Four positioning clamps 55 are provided, forming a cross-shaped structure. These four clamps clamp the transverse positioning strip 51, the reinforcing steel frame 2, and the longitudinal positioning strip 52. The cross-shaped structure formed by the four positioning clamps 55 positions the transverse and longitudinal positioning strips 51 and 52, preventing them from tilting.

[0038] Two adjacent positioning clamps 55 are connected to each other by bolts 56, and a rotating head 57 is fixedly installed at the end of the bolt 56. One end of the bolt 56 connected to the rotating head 57 is rotatably connected to the positioning clamp 55, and the other end of the bolt 56 is threadedly connected to the positioning clamp 55. By rotating the rotating head 57 to rotate the bolt 56, the distance between the positioning clamps 55 in adjacent positions can be adjusted to accommodate transverse positioning strips 51 and longitudinal positioning strips 52 of different diameters.

[0039] In this embodiment, the transverse reinforcing bars 3 and longitudinal reinforcing bars 4 are positioned by the transverse positioning strip 51 and the longitudinal positioning strip 52, establishing the position of each transverse reinforcing bar 3 and longitudinal reinforcing bar 4, so that the support of the transverse reinforcing bars 3 and longitudinal reinforcing bars 4 on the supporting steel plate 1 is more uniform. By rotating the rotating head 57 to rotate the bolt 56, the distance between the positioning clamps 55 at adjacent positions can be adjusted to accommodate transverse positioning strips 51 and longitudinal positioning strips 52 of different diameters, improve the clamping force, prevent the transverse reinforcing bars 3 and longitudinal reinforcing bars 4 from loosening, and improve the construction accuracy and stability.

[0040] Example 2

[0041] Based on Example 1, this example proposes a steel formwork support for dry canal construction, such as... Figure 4 and Figure 5 As shown, the outer wall of the positioning clamp 55 is provided with an obstruction mechanism 6. The obstruction mechanism 6 includes a guide rod 61, which slides horizontally along the diameter direction of the rotating head 57. An elastic ring 62 is fixedly installed at the end of the guide rod 61, and a rotation obstruction member is provided on the outer wall of the elastic ring 62.

[0042] The rotational obstruction includes two protrusions 63, which are symmetrically distributed on the outer wall of the elastic ring 62. An obstruction block 64 is fixedly installed on the outer wall of the positioning clamp 55, and the obstruction block 64 is located on the rotation path of the protrusions 63.

[0043] By restricting the position of the protrusion 63 by the obstruction block 64, the guide rod 61, the elastic ring 62 and the protrusion 63 cannot rotate, and the screw head 57 is connected to the guide rod 61, so the screw head 57 cannot drive the bolt 56 to rotate.

[0044] By pinching the ends of the two guide rods 61, the elastic ring 62 is squeezed and deformed into a circle. At this time, the obstruction block 64 will not be on the rotation path of the protrusion 63, and the bolt 56 and the rotating head 57 can be rotated to change the distance between the two adjacent positioning clamps 55.

[0045] The elastic ring 62 has an elliptical structure, and its thickness is greater than that of the obstruction block 64. This prevents the obstruction block 64 from hindering the tool and hand when the elastic ring 62 is rotated.

[0046] In this embodiment, the position of the protrusion 63 is restricted by the obstruction block 64, so that the guide rod 61, elastic ring 62 and protrusion 63 cannot rotate. Since the rotating head 57 is connected to the guide rod 61, the rotating head 57 cannot drive the bolt 56 to rotate. The positions of the four positioning clamps 55 cannot be changed, thus avoiding the vibration generated during the processing of the bracket, which would cause the bolt 56 to vibrate and move the positioning clamps 55, affecting the stability of construction.

[0047] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
