Description

Technical Field

[0001] This application relates to the field of bridge deck paving, and in particular to a new type of bridge deck paving structure and its construction method. Background Art

[0002] The bridge deck paving layer refers to the protective layer laid on the bridge deck. The functions of the bridge deck paving layer are mainly twofold: First, it reduces the phenomenon that the bridge deck is directly worn when vehicles drive on the bridge deck; Second, it ensures the flatness of the bridge deck and improves the driving stability of vehicles on the bridge deck.

[0003] In traditional bridge deck paving construction, a elevation strip needs to be constructed on the bridge deck before the paving layer construction. The pre-laid elevation strip is the track for the concrete paver to walk on the bridge deck and also the construction reference strip for the paving layer. After the elevation strip is cured, the binding operation of U-shaped steel bars needs to be carried out on the bridge deck. Most of the U-shaped steel bars are fixed by electric welding. After all the U-shaped steel bars are installed, the construction personnel can carry out the concrete paving construction at the bottom end of the installed U-shaped steel bars to form the bridge deck paving layer.

[0004] Regarding the above related technologies, the inventor believes that there are defects that it is difficult to control the spacing of all elevation points in the traditional elevation strip construction, and the construction accuracy of the U-shaped steel bars manually arranged by the construction personnel is also low, thus it is difficult to ensure the flatness of the bridge deck paving layer. Summary of the Invention

[0005] In a first aspect, in order to improve the problem that it is difficult to ensure the flatness of the bridge deck paving layer, this application provides a new type of bridge deck paving structure.

[0006] The new type of bridge deck paving structure provided by this application adopts the following technical solutions:

[0007] A new type of bridge deck paving structure includes U-shaped steel bars, mounting frames, and multiple groups of mutually adapted comb plates; each group of the comb plates includes a fixed side plate and multiple extension bars. All the extension bars are arranged on one side of the fixed side plate in the width direction. A reserved groove is arranged between two adjacent extension bars; one end of the extension bar away from the fixed side plate is located in the opposite reserved groove so that two symmetrically arranged groups of comb plates are abutted; each fixed side plate and the foundation for bearing the fixed side plate are jointly provided with connecting bolts, and an embedded groove for receiving the end of the connecting bolt is arranged on the upper surface of the fixed side plate; the mounting frame is located on the side where two symmetrically arranged comb plates are away from each other. The mounting frame includes two support plates and two positioning blocks; the positioning blocks are arranged at the length direction ends of the U-shaped steel bars. One end of the positioning block away from the U-shaped steel bar is slidably arranged on the upper surface of the support plate, and a locking assembly for defining the position of the positioning block on the support plate is jointly provided between the positioning block and the support plate.

[0008] By adopting the above technical scheme, the mutually adapted comb plates are connected as a whole by extending the bars into the reserved grooves facing each other, and then the upper surface of the comb plates is at the same horizontal plane to form an elevation belt with the same elevation control points, and serve as a construction reference belt for the bridge deck pavement layer to ensure the forming quality of the bridge deck pavement layer and the flatness of the top after forming; at the same time, the comb plates can ensure the forming quality of the bridge deck pavement layer and its adjacent parts by their own hard texture and non-deformable characteristics; the support plates are level at all places to ensure the consistent positioning height of all U-shaped bars on the support plates; the positioning blocks ensure the positioning stability of the U-shaped bars on the support plates by increasing the contact area of the U-shaped bars on the support plates, and at the same time, it is convenient for construction personnel to quickly adjust the spacing between adjacent U-shaped bars by sliding the positioning blocks, thereby further improving the forming quality and accuracy of the bridge deck pavement layer.

[0009] Preferably, adjacent extension bars are commonly provided with a connecting assembly, which includes a connecting column, an end plate and a fixing bolt; the outer side wall of each extension bar is penetrated with a clearance hole for facilitating the passage of the connecting column, the end plate is arranged at one end of two adjacent connecting columns facing each other, and the fixing bolt is used to fix and connect the two end plates that are close to each other.

[0010] By adopting the above technical solution, the connecting column passes through the clearance hole to simultaneously connect all adjacent extension strips, thereby improving the connection strength of the extension strips after staggered offset, and further improving the connection strength of adjacent comb plates, thereby further ensuring the molding stability of the elevation belt.

[0011] Preferably, a plurality of receiving grooves are arranged on the upper surface of the support plate, and a horizontal member is arranged in each receiving groove of the support plate.

[0012] By adopting the above technical solution, the horizontal member is used to ensure that the upper surface of the support plate is in a horizontal state everywhere, so that after any displacement and positioning of the U-shaped reinforcement on the upper surface of the support plate, the adjacent U-shaped reinforcements can be ensured to be at the same height, thereby improving the compaction degree of concrete at the U-shaped reinforcement and ensuring the forming quality of the bridge deck pavement layer.

[0013] Preferably, a plurality of groups of adjustment parts are provided on the lower surface of the support plate, and each group of adjustment parts includes an adjustment rod and a bottom support plate; a mounting groove which cooperates with the thread of the adjustment rod is provided on the lower surface of the support plate, and the bottom support plate is provided at one end of the adjustment rod away from the support plate.

[0014] By adopting the above technical solution, when the ground fluctuates up and down due to the ground level, the operator can adjust the distance between the bottom support plate and the support plate by screwing the adjustment rod, thereby changing the height of the support plate from the ground to ensure that all parts of the upper surface of the support plate are in a horizontal state.

[0015] Preferably, the locking assembly includes two external connection plates, two limiting bars, and a plurality of locking bolts. The two external connection plates are symmetrically arranged on the outer side wall of the positioning block. The two limiting bars are symmetrically arranged on the upper surface of the support plate. Guide grooves for the external connection plates to abut against are respectively arranged on the sides of the two limiting bars facing each other. The locking bolts are used to fixedly connect the limiting bars and the external connection plates.

[0016] By adopting the above technical solution, the external connection plate abuts into the guide groove to limit the relative position of the positioning block on the support plate. At the same time, it effectively reduces the phenomenon of left and right sway when the positioning block slides on the support plate. The locking bolts fixedly connect the limiting bars and the external connection plates, thereby effectively ensuring the position stability of the U-shaped rib fixed on the upper surface of the support plate, as well as the forming quality and top flatness of the bridge deck paving layer.

[0017] Preferably, scale lines for facilitating the positioning of the positioning block are arranged on the upper surface of the support plate along the length direction.

[0018] By adopting the above technical solution, the scale lines facilitate the construction workers to accurately and quickly adjust the distance between adjacent positioning blocks, thereby effectively ensuring the uniformity of the distance between adjacent U-shaped ribs, improving the distribution and compaction uniformity of the concrete in the U-shaped ribs, and further improving the top flatness of the bridge deck paving layer after forming.

[0019] Preferably, two groove-shaped holes are symmetrically arranged on the lower surface of the positioning block. Guide wheels are rotatably arranged on the positioning block at the groove-shaped holes. A sliding groove for the guide wheels to abut against is arranged on the upper surface of the support plate.

[0020] By adopting the above technical solution, the guide wheels slide in the sliding groove, converting the sliding friction between the positioning block and the support plate into rolling friction. This process greatly reduces the static friction coefficient when the positioning block slides on the support plate, thereby improving the convenience for the construction workers to adjust the position of the positioning block.

[0021] Preferably, a fastening assembly is jointly arranged on the U-shaped rib and the positioning block. The fastening assembly includes a butting plate and fastening bolts; the butting plate is arranged at both ends of the U-shaped rib in the length direction, and the fastening bolts are used to fixedly connect the butting plate and the positioning block.

[0022] By adopting the above technical solution, the butting plate increases the contact between the U-shaped rib and the positioning block. After the fastening bolts fixedly connect the butting plate and the positioning block, the position stability of the U-shaped rib on the positioning block is greatly improved; at the same time, when the U-shaped rib is impacted and deformed during construction, the construction workers can rotate the fastening bolts to quickly disassemble the U-shaped rib and replace it with a new one.

[0023] Preferably, an adaptation groove is arranged on the upper surface of the positioning block, and the butting plate is located in the adaptation groove.

[0024] By adopting the above technical solution, the abutment plate is inserted into the adapter groove to limit the position of the abutment plate relative to the positioning block, thereby effectively reducing the looseness and deviation of the abutment plate on the upper surface of the positioning block, and further improving the position stability of the U-shaped rib on the positioning block.

[0025] Secondly, in order to improve the problem of low work efficiency of construction workers in laying bridge deck pavement layers, the present application provides a new construction method for a bridge deck pavement structure.

[0026] The present application provides a novel construction method for a bridge deck pavement structure, comprising the following construction steps:

[0027] S100, laying the elevation belt: insert the extension strips of the comb plate into the reserved grooves of the symmetrical comb plates, so that the symmetrical extension strips are staggered and abutted, and the symmetrical comb plates are connected as a whole; pass the connecting column through all the clearance holes in sequence, so that all adjacent extension strips are connected as a whole, and the adjacent fixed side plates are tightly abutted; finally, the fixed side plates and the foundation are fixedly connected by connecting bolts, so that all the comb plates are fixedly connected as a whole, forming an elevation belt, which is used as a construction reference belt for the bridge deck pavement layer;

[0028] S200, install U-shaped ribs: push the guide wheel into the sliding groove, push the external plate into the guide groove, and quickly adjust the position of the positioning block on the support plate by moving the guide wheel in the sliding groove; after determining the distance between two adjacent positioning blocks according to the scale line, fix the limit strip and the external plate with locking bolts to limit the position of the positioning block and the U-shaped rib on the support plate.

[0029] S300, concrete pouring: pour concrete at the location of the U-shaped reinforcement, control the pouring height of the concrete to be flush with the upper surface of the comb plate, and thus form a bridge deck pavement layer with uniform texture and flat top.

[0030] By adopting the above technical solution, construction workers can lay the bridge deck pavement layer quickly and efficiently.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. All the comb plates that are fixedly connected can jointly form an elevation belt with the same elevation control points, which can be used as a construction reference belt for the bridge deck pavement layer to ensure the forming quality of the bridge deck pavement layer and the top flatness after forming; the support plate has the characteristic of being flush with the top wall to ensure that all U-shaped bars are positioned at the same height on the support plate. The positioning block can slide quickly on the support plate to adjust the spacing between adjacent U-shaped bars and effectively ensure the position stability of the U-shaped bars on the support plate, thereby further improving the forming quality of the bridge deck pavement layer and the top flatness after forming;

[0033] 2. The guide wheel slides within the guide groove to quickly adjust the position of the positioning block on the support plate, thereby facilitating the construction workers to quickly adjust the spacing between adjacent U-shaped bars, ensuring the compaction degree of the concrete laid within the U-shaped bars, and further improving the top flatness of the formed bridge deck paving layer.

Detailed Description of the Embodiment

[0040] The following will further elaborate on the present application in conjunction with the attached Figures 1-5 for a more detailed description.

[0041] An embodiment of the present application discloses a novel bridge deck paving structure. Referring to Figure 1 and Figure 2 , a novel bridge deck paving structure includes a U-shaped bar 3, a mounting frame 2, and multiple groups of mutually adapted comb tooth plates 1. Two symmetrically arranged groups of comb tooth plates 1 abut against each other to form a leveling band with the same elevation control points everywhere, ensuring the construction accuracy and top wall flatness of the bridge deck paving layer.

[0042] Referring to Figure 3The mounting frame 2 includes two support plates 21 and two positioning blocks 22. The support plates 21 are stably positioned on the foundation by adjusting members 5 to ensure that the upper surface of the support plates 21 is level everywhere. The positioning blocks 22 are fixed to both ends of the length direction of the U-shaped ribs 3 by fastening components 6. Each positioning block 22 is slidably arranged on the upper surface of the support plate 21 to ensure that all U-shaped ribs 3 maintain the same height at any position of the support plate 21. At the same time, the U-shaped ribs 3 can adjust the distance between adjacent U-shaped ribs 3 by sliding the positioning blocks 22 on the support plates 21. The positioning blocks 22 and the support plates 21 are also provided with locking components 7 to ensure the position stability of the U-shaped ribs 3 after positioning.

[0043] Reference Figure 1 and Figure 2 The comb tooth plates 1 are made of solid steel plates. In the embodiment of the present invention, the number of the comb tooth plates 1 can be four groups. Each group of comb tooth plates 1 includes a fixed side plate 11 and a plurality of extension strips 12. All the extension strips 12 are integrally formed on one side of the fixed side plate 11 in the width direction. The upper surfaces of all the extension strips 12 are coplanar with the upper surface of the fixed side plate 11. Two adjacent extension strips 12 are gap-matched and jointly form a reserved groove 121. When two mutually symmetrical groups of comb tooth plates 1 are assembled, the extension strips 12 of one group of comb tooth plates 1 can be inserted into the reserved groove 121 of the other group of comb tooth plates 1, thereby limiting the relative positions of the two groups of comb tooth plates 1.

[0044] Reference Figure 1 and Figure 2 All adjacent extension bars 12 are provided with a connection assembly 4, which includes a connection column 41, an end plate 42 and a fixing bolt 43. A clearance hole 122 is provided through the outer wall of each extension bar 12 along the thickness direction, and the outer diameter of the connection column 41 is matched with the inner diameter of the clearance hole 122. Then, all adjacent clearance holes 122 are penetrated through the connection column 41 to further improve the connection strength of the two mutually symmetrical comb plates 1.

[0045] Reference Figure 2 The end plate 42 is vertically welded to the ends of the two adjacent connecting columns 41 that are close to each other. After the side walls of the two adjacent fixed side plates 11 facing each other are abutted, the two end plates 42 that are close to each other are abutted. The rod body of the fixing bolt 43 can pass through one of the end plates 42 and be threadedly tightened in the preset thread groove on the outer side wall of the other end plate 42, so that the two end plates 42 that are close to each other are fixedly connected, thereby further improving the connection strength of the adjacent comb plates 1.

[0046] Reference Figure 2, the fixed side plate 11 and the foundation on which the fixed side plate 11 is installed are jointly provided with connecting bolts 111. In this embodiment, the rod body of the connecting bolt 111 can penetrate through the fixed side plate 11 and be screwed tightly into the threaded groove reserved on the top wall of the foundation, so that the fixed side plate 11 is fixed on the foundation. All adjacent comb plates 1 are fixed as a whole, thereby forming a elevation band with the same elevation control points everywhere, ensuring the accuracy of the bridge deck pavement construction and the top flatness of the bridge deck pavement after forming.

[0047] Refer to Figure 2 , the top wall of the fixed side plate 11 is provided with embedded grooves 112 equal in number to the connecting bolts 111. The inner diameter of the embedded groove 112 is larger than the outer diameter of the end of the connecting bolt 111 to accommodate the end of the connecting bolt 111 and ensure the top flatness of the fixed side plate 11. At the same time, the influence of external factors on the connecting bolt 111 is reduced, and the connection strength between the fixed side plate 11 and the foundation is improved.

[0048] Refer to Figure 1 and Figure 3 , the mounting brackets 2 are respectively arranged on the sides of two groups of symmetrically arranged comb plates 1 away from each other to accurately install the U-shaped bars 3. The support plate 21 extends along the length direction of the fixed side plate 11. In this embodiment, the support plate 21 is directly seated on the foundation. After the support plate 21 is positioned, the construction worker can weld and fix the support plate 21 to the embedded steel bars on the foundation.

[0049] Refer to Figure 4 , two receiving grooves 211 are arranged on the upper surface of the support plate 21 along the length direction, and a horizontal member 212 is adhered in each receiving groove 211 of the support plate 21. In this embodiment, the horizontal member 212 is a cylindrical level with a spirit level. When the top wall of the support plate 21 is horizontal everywhere, the spirit level of the horizontal member 212 is exactly located in the middle position of the cylinder, so that when the U-shaped bars 3 are installed at various positions on the upper surface of the support plate 21, they are all at the same horizontal height.

[0050] Refer to Figure 4 and Figure 5 , the adjusting member 5 includes an adjusting rod 51 and a bottom support plate 52. In this embodiment, the adjusting rod 51 is a screw rod. The bottom support plate 52 is welded to one end of the adjusting rod 51 away from the support plate 21 in the horizontal direction. An installation groove 213 is provided on the lower surface of the support plate 21, and the installation groove 213 is a threaded groove. One end of the adjusting rod 51 close to the support plate 21 can be screwed into the installation groove 213. When there are uneven foundation pits on the foundation, the operator can screw the adjusting rod 51 to change the distance between the bottom support plate 52 and the support plate 21, thereby ensuring that the top of the support plate 21 is horizontal everywhere, so as to position the block 22 to install the U-shaped bars 3 at any position on the upper surface of the horizontal plate.

[0051] Refer toFigure 4 The positioning block 22 is a solid steel block. Two groove-shaped holes 221 are symmetrically arranged on the lower surface of the positioning block 22. A guide wheel 222 is rotatably arranged at the groove-shaped hole 221 of the positioning block 22 through a pin. The guide wheel 222 is a roller, and the guide wheel 222 extends below the positioning block 22. A sliding groove 214 for the guide wheel 222 to abut against is arranged on the upper surface of the support plate 21 along the length direction. The guide wheel 222 slides in the sliding groove 214 to quickly adjust the position of the positioning block 22 on the support plate 21, and further quickly position the U-shaped rib 3.

[0052] Refer to Figure 4 The fastening assembly 6 includes a contact plate 61 and a fastening bolt 62. The contact plate 61 is welded horizontally at both ends of the U-shaped rib 3 in the length direction. An adaptation groove 223 with an inner diameter size adapted to the outer peripheral size of the contact plate 61 is arranged on the upper surface of the positioning block 22. After the contact plate 61 abuts into the inner cavity of the adaptation groove 223, the fastening bolt 62 fixedly connects the contact plate 61 and the positioning block 22 to fixedly connect the end of the U-shaped rib 3 in the length direction with the positioning block 22. When the positioning block 22 is fixed and positioned on the upper surface of the support plate 21, the U-shaped rib 3 is also stably positioned above the foundation.

[0053] Refer to Figure 4 Engraved scale lines 215 are arranged on the upper surface of the support plate 21 along the length direction. In this embodiment, the scale lines 215 are decimeter-level scale lines 215. The positioning block 22 can be based on the scale lines 215 to quickly determine and accurately adjust the distance between two adjacent positioning blocks 22, so as to ensure the uniformity of the distribution of the U-shaped ribs 3 on the support plate 21 and the flatness of the top surface after the formation of the bridge deck paving layer.

[0054] Refer to Figure 4 The locking assembly 7 includes two external connection plates 72, two limiting strips 71 and a plurality of locking bolts 73. The two limiting strips 71 are symmetrically welded on the upper surface of the support plate 21. The limiting strips 71 extend along the length direction of the support plate 21, and the two limiting strips 71 are respectively located on both sides of the positioning block 22 in the width direction. The two external connection plates 72 are respectively welded on the outer side walls of the positioning block 22 horizontally. The two external connection plates 72 are respectively located on both sides of the positioning block 22 in the width direction, and the lower surface of the external connection plate 72 is coplanar with the lower surface of the positioning block 22. A guide groove 711 is arranged on the side of the limiting strip 71 facing the external connection plate 72. The inner diameter size of the guide groove 711 is adapted to the outer peripheral size of the external connection plate 72. Then, the external connection plate 72 abuts into the guide groove 711 and slides to ensure the sliding stability of the positioning block 22 on the support plate 21.

[0055] Refer to Figure 4When the positioning block 22 is positioned on the upper surface of the support plate 21, the rod body of the locking bolt 73 can pass through the limit strip 71 and be screwed into the preset thread groove on the upper surface of the external plate 72, so that the external plate 72 is fixed in the guide groove 711, thereby making the positioning block 22 stably positioned on the upper surface of the support plate 21, and the U-shaped rib 3 stably fixed on the upper surface of the support plate 21, so as to ensure the construction accuracy of the bridge deck pavement layer and the flatness of the top after forming.

[0056] The implementation principle of a new bridge deck pavement structure in the embodiment of the present application is as follows: the extension strip 12 of the comb tooth plate 1 is inserted into the reserved groove 121 of the relative comb tooth plate 1, so that the two symmetrical comb tooth plates 1 are connected as a whole. After the connecting column 41 passes through all adjacent clearance holes 122, all adjacent extension strips 12 are connected as a whole, thereby improving the connection strength of adjacent comb tooth plates 1. After the connecting bolts 111 are fixedly connected to the fixed side plate 11 and the foundation, all comb tooth plates 1 are fixed as a whole. At this time, the top wall of the comb tooth plate 1 is in the same horizontal plane at all places, thereby forming an elevation belt with the same elevation control points everywhere, so as to ensure the accuracy of the control construction of the bridge deck pavement layer and the flatness of the top of the bridge deck pavement layer after forming.

[0057] The upper surface of the support plate 21 is level everywhere to ensure that all U-shaped ribs 3 are installed at the same height on the support plate 21. The external plate 72 slides quickly in the guide groove 711 and is positioned on the upper surface of the support plate 21 based on the scale line 215 to ensure that the positioning spacing of adjacent U-shaped ribs 3 on the support plate 21 is equal, thereby effectively ensuring the pouring compaction and stability of the concrete on the U-shaped ribs 3, and further improving the construction accuracy of the bridge deck pavement layer and the top flatness after forming.

[0058] The present application also discloses a novel construction method of a bridge deck pavement structure. The novel construction method of a bridge deck pavement structure includes the following construction steps:

[0059] S100, laying elevation tape: first, the extension strips 12 of the comb plate 1 are pushed into the reserved grooves 121 of the comb plates 1 at symmetrical positions, so that the mutually symmetrical extension strips 12 are staggered and abutted, thereby connecting the two mutually symmetrical comb plates 1 into a whole.

[0060] Next, the connecting column 41 is passed through all the clearance holes 122 in sequence, so that all adjacent extension bars 12 are connected as a whole, and the adjacent fixed side plates 11 are tightly abutted against each other to improve the connection strength of the adjacent comb plates 1. Finally, the fixed side plates 11 and the foundation are fixedly connected by connecting bolts 111, so that all comb plates 1 are fixedly connected as a whole.

[0061] At this time, the top walls of all parts of the comb tooth plate 1 are on the same horizontal plane, thereby forming an elevation band with the same elevation control points everywhere. As a construction reference band for the bridge deck paving layer, the elevation band can effectively ensure the accuracy of the bridge deck paving layer during construction and the flatness of the top surface of the bridge deck paving layer after it is formed;

[0062] S200. Install the U-shaped bars 3: Insert the guide wheels 222 into the sliding grooves 214, and insert the external connecting plate 72 into the guide grooves 711. As the guide wheels 222 slide along the length direction of the sliding grooves 214, the position of the positioning blocks 22 on the support plate 21 can be quickly adjusted. Construction workers can determine the distance between two adjacent positioning blocks 22 according to the scale lines 215 to ensure the uniform distribution of adjacent U-shaped bars 3, thereby ensuring the ramming of the concrete and the forming stability of the bridge deck paving layer.

[0063] After determining the position of the positioning blocks 22 on the support plate 21, construction workers can pass the rod body of the locking bolt 73 through the limiting strip 71 and thread it tightly into the threaded groove preset on the outer side wall of the external connecting plate 72, so that the external connecting plate 72 is fixedly connected to the limiting strip 71, and the positioning blocks 22 are stably fixed on the upper surface of the support plate 21, thereby positioning the U-shaped bars 3 on the support plate 21.

[0064] S300. Concrete pouring: Pour the concrete at the position where the U-shaped bars 3 are located, so that the pouring height of the concrete is on the same horizontal plane as the upper surface of the comb tooth plate 1, thereby forming a bridge deck paving layer with uniform texture and a flat top surface.

[0065] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
