Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a prefabricated bracket device for steel sheet pile grooves. Background Technology

[0002] In the field of building construction, sheet piles are a common retaining structure widely used in various foundation projects, such as deep foundation pit support and riverbank protection. During the construction of sheet piles, it is often necessary to install prefabricated bracket devices in the grooves of the sheet piles to provide support and fixing points for subsequent construction operations, such as placing walers.

[0003] However, existing prefabricated bracket devices for sheet pile grooves have several shortcomings. Firstly, in actual construction environments, the front sheet pile may tilt or become uneven at its contact point with the bracket device's sealing back plate due to geological conditions, construction operations, or other factors. In such cases, traditional bracket devices struggle to automatically adapt to the tilt or unevenness of the front sheet pile, causing the waler bearing plate to fail to maintain a horizontal position. This, in turn, affects the placement and stability of the waler, increasing construction difficulty and safety risks.

[0004] On the other hand, when the walers are placed on the waler support plate, there is a lack of effective limiting and fixing mechanisms. During construction, the walers may move on the waler support plate due to various external forces, which will not only affect the construction accuracy, but may also have an adverse effect on the overall stability of the enclosure structure, and may even cause safety accidents.

[0005] Therefore, a prefabricated corbel device for steel sheet pile grooves is proposed to solve the problems of uneven stress and unstable installation in traditional walers. Utility Model Content

[0006] The purpose of this utility model is to provide an assembled bracket device for steel sheet pile grooves, in order to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a prefabricated bracket device for steel sheet pile grooves, including a bracket, a rear steel sheet pile, a waler and a front steel sheet pile, wherein the front steel sheet pile and the rear steel sheet pile are open-type structures and the opening directions are opposite, the front steel sheet pile and the rear steel sheet pile are alternately distributed and fixed to each other, and the side of the rear steel sheet pile away from the opening is fixed to the waler;

[0008] The cow leg includes a slit back plate, a hook is fixed on the top of the slit back plate, and a fastening bolt that passes through the hook is fixed on the end face of the slit back plate. The fastening bolt is threaded with a nut.

[0009] A support plate and a waler bearing plate are installed on the front side of the caulking back plate. The support plate is located above the waler bearing plate and is fixed to the caulking back plate. The waler bearing plate is a trapezoidal hollow structure with its inclined surface facing the caulking back plate and hinged to the support plate.

[0010] The top of the inner wall bearing plate is slidably connected to a hinge block 1, and the end of the support plate is hinged to a wall waler backing plate. The wall waler backing plate is hinged to the hinge block 1 via a connecting rod 2.

[0011] The waler bearing plate is equipped with a sliding rod and a push block. The sliding rod is connected to the hinge block through the connecting rod three. One end of the sliding rod is in contact with the front steel sheet pile, and the other end is connected to the sliding block through the spring one.

[0012] The waler support plate is provided with a push plate and a limiting component. The push plate is connected to the mounting groove through a spring 2, and the push plate is connected to the push block through a spring 3. The limiting component slides with the waler support plate through a limiting groove and extends to the outside of the limiting hole through a connecting rod 4.

[0013] The present invention further explains that the support plate and the slit back plate are arranged perpendicularly, the trapezoidal inclined surface of the waler bearing plate forms an angle of 45° with the longer side, and the hinge point is located at this angle.

[0014] The present invention further illustrates that a sliding hole is provided on the waler backing plate, and a slidable rotating rod is provided in the sliding hole.

[0015] The present invention further explains that the push plate has through holes on its two end faces, and the size of the through holes is adapted to the three cross-sectional dimensions of the spring.

[0016] The present invention further explains that the limiting component includes a support block, a spring, and a limiting block, wherein the limiting block slides within the slot via the spring.

[0017] This utility model further illustrates that the longer side end face of the waler bearing plate is provided with a limiting hole, and the diameter of the connecting rod four is smaller than the diameter of the limiting hole.

[0018] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: The prefabricated bracket device for the steel sheet pile groove of this utility model can automatically adapt to the tilt or unevenness of the front steel sheet pile. When the front steel sheet pile tilts or is uneven at the contact point with the caulking back plate, through the coordinated action of components such as the support plate, waler back plate, hinge block one, connecting rod three, and sliding rod, the waler bearing plate can rotate around the hinge point with the caulking back plate as the center, and finally automatically adjust to a horizontal state. This feature ensures that the waler can always be placed on a stable horizontal surface, greatly improving the convenience and accuracy of construction, and reducing construction difficulties and safety hazards caused by the waler bearing plate not being horizontal.

[0019] This utility model possesses an effective waler limiting and fixing function. When the waler is placed on the waler support plate, the weight of the waler will cause push plates one and two to move downwards. When the through hole on push plate two completely coincides with spring three, spring three pushes the limiting component to move, and connecting rod four extends out from the waler support plate through the limiting hole, thereby restricting the movement of the waler on the waler support plate. This design can effectively prevent the waler from shifting due to external forces during construction, ensuring the overall stability and construction accuracy of the enclosure structure and improving the project quality.

[0032] like Figure 2 As shown, in some embodiments, the caulking back plate 130 is equipped with a support plate 104 and a waler bearing plate 105 on one side of the front sheet pile 4 in the opening direction. The support plate 104 is located above the waler bearing plate 105 and fixed to the caulking back plate 130. The waler bearing plate 105 is a trapezoidal plate and hollow inside. The trapezoidal inclined surface of the waler bearing plate 105 faces the caulking back plate 130. The longer side of the waler bearing plate 105 forms a 45° angle with the inclined surface. The waler bearing plate 105 is hinged to the front sheet pile 4 at the angle.

[0033] like Figure 4 As shown, in some embodiments, the waler support plate 105 has an installation hole 106 on its end face near the support plate 104, and a hinge block 107 is slidably connected inside the waler support plate 105. The hinge block 107 is located at the top inside the waler support plate 105 and between the installation hole 106 and the caulking back plate 130.

[0034] One end of the support plate 104 is fixed to the slit back plate 130, and the other end is hinged to a waler back plate 108. The waler back plate 108 is arranged vertically downward, with one end hinged to the support plate 104 and the other end hinged to the hinge block 107 via a connecting rod 2 109.

[0035] A sliding hole 1081 is provided on the end face of the waler backing plate 108. A rotating rod 110 is provided in the sliding hole 1081. The rotating rod 110 slides in the sliding hole 1081 and is rotatably connected between the mounting holes 106.

[0036] like Figure 2 As shown, in some embodiments, a sliding rod 111 and a push block 115 are installed inside the waler support plate 105. The sliding rod 111 and the push block 115 are in contact with the inner wall of the shorter side of the waler support plate 105. A certain distance is left between the sliding rod 111 and the push block 115. The sliding rod 111 is close to the side of the inclined edge of the waler support plate 105, and the push block 115 is close to the side of the right angle edge of the waler support plate 105.

[0037] like Figure 4 As shown, in some embodiments, the sidewall of the sliding rod 111 is hinged to the hinge block 107 via a connecting rod 114. One end of the sliding rod 111 passes through the waler bearing plate 105 and contacts the front sheet pile 1, while the other end is fixed to a sliding block 113 via a spring 112.

[0038] like Figure 5 As shown, in some embodiments, a mounting groove 116 is provided on the end face of the waler support plate 105 near the support plate 104. The mounting groove 116 is located between the push block 115 and the right-angle side of the waler support plate 105. A push plate 118 is fixedly connected in the mounting groove 116 by a spring 117. The push plate 118 includes a push plate 119. The push plate 119 penetrates the waler support plate 105 and fits against the inner wall of the shorter side. A through hole 120 is provided on the end face of the shorter side of the waler support plate 105. The through hole 120 corresponds to the position of the push plate 119 and is adapted in size.

[0039] like Figure 5 and Figure 6As shown, in some embodiments, a spring 121 is provided between the push block 115 and the push plate 119. One end of the spring 121 is fixed to the push block 115, and the other end is in contact with the push plate 119. A limiting component 122 is provided on the other side of the push plate 119. The limiting component 122 slides within the waler support plate 105. A limiting channel 123 is formed within the waler support plate 105. The limiting channel 123 is located on the sliding path of the limiting component 122.

[0040] The limiting component 122 includes a support block 124, which is in contact with the shorter inner wall of the waler support plate 105. The support block 124 has a slot 125 facing the shorter side of the waler support plate 105. A limiting block 127 is fixed in the slot by a spring 126. The limiting block 127 slides in the slot 125 and is adapted to the limiting channel 123.

[0041] A limiting hole 129 is provided on the longer end face of the waler support plate 105. The limiting hole 128 is close to the right-angle side of the waler support plate 105. A connecting rod 128 is hinged above the limiting component 122. The diameter of the limiting hole 129 is larger than the diameter of the connecting rod 128, allowing the connecting rod 128 to extend out.

[0042] It should be noted that the support plate 104 is perpendicular to the slit back plate 130.

[0043] It should be noted that a through hole is provided on the end face of the push plate 2 119, and the through hole is the same size as the cross-section of the spring 3 121.

[0044] Working principle: The hook 102 is fixed to the front steel sheet pile 4 by the fastening bolt 101.

[0045] When the front sheet pile 4 is vertical and the surface is flat, the waler bearing plate 105 is exactly perpendicular to the caulking back plate 130. At this time, the rotating rod 110 is at the center of the sliding hole 1081, and the included angle between the support plate 104 and the waler back plate 108 is a right angle.

[0046] When the front sheet pile 4 is tilted or the contact point with the caulking back plate 130 is uneven, causing the caulking back plate 130 to tilt towards the waler bearing plate 105, since the support plate 104 is perpendicular to the caulking back plate 130, the included angle between the support plate 104 and the waler back plate 108 gradually becomes an acute angle. The rotating rod 110 slides to above the center of the sliding hole 1081, and the hinge block 107 slides towards the caulking back plate 130. The hinge block 107 drives the sliding rod 111 to slide towards the caulking back plate 130 through the connecting rod 114. The sliding rod 111 drives the waler bearing plate 105 to rotate around the hinge point between the waler bearing plate 105 and the caulking back plate 130. When the sliding rod 111 stops sliding, the waler bearing plate 105 is exactly in a horizontal state.

[0047] When the front sheet pile 4 is tilted or the contact area with the caulking back plate 130 is uneven, causing the caulking back plate 130 to tilt in the opposite direction to the waler bearing plate 105, since the support plate 104 is perpendicular to the caulking back plate 130, the included angle between the support plate 104 and the waler abutment plate 108 gradually becomes an obtuse angle. The rotating rod 110 slides to below the center of the sliding hole 1081, and the hinge block 107 moves towards the sliding block 113. The hinge block 107 slides in the direction of the sliding rod 111 towards the sliding block 113 via the connecting rod 114. Under the action of gravity, the waler support plate 105 rotates around the hinge point between the waler support plate 105 and the slit back plate 130. When the sliding rod 111 stops sliding, it gives a reaction force to the waler support plate 105. At this time, the waler support plate 105 stops rotating and is just in a horizontal state.

[0048] When the waler 3 is placed above the waler support plate 105, the waler 3 moves the push plate 118 downward under the action of gravity. The push plate 118 drives the push plate 2 119 downward. When the push plate 118 contacts the waler support plate 105, the through hole on the push plate 2 119 completely coincides with the spring 3 121. The spring 3 121 passes through the through hole and contacts the limiting component 122. The spring 3 121 pushes the limiting component 122 to move in the opposite direction to the spring 3 121. The connecting rod 4 128 extends out of the waler support plate 105 through the limiting hole 129, restricting the movement of the waler 3 on the waler support plate 105.
