Description

Technical Field

[0001] This application relates to the technical field of airport drainage ditch construction, and in particular to a dowel bar bracket for airport drainage ditches. Background Technology

[0002] The airport drainage ditch was constructed using segmented cast-in-place construction. During the construction process, dowel bars were used to connect the transverse joints of adjacent segments. The purpose of this was to transfer lateral loads, coordinate structural deformation, and ensure the overall stress balance and long-term stability of the drainage ditch.

[0003] The common method for installing dowel bars on site is as follows: first, the installation position of the dowel bar is located according to the design spacing and elevation of the transverse joints of the drainage ditch segment. Then, holes are drilled in the corresponding positions of the formwork, and one end of the dowel bar is fixed to the formwork. This installation method will cause the dowel bar to shift and tilt during the concrete vibration process, resulting in the failure to guarantee the force transmission performance of the dowel bar.

[0004] Therefore, this application proposes a dowel bar bracket for airport drainage ditches, which can fix the position and extension length of the dowel bar, effectively prevent the dowel bar from shifting and tilting during concrete pouring, ensure that the axis of the dowel bar is consistent with the installation position, and improve the overall force transmission performance and construction accuracy of the structure. Utility Model Content

[0005] This application provides a dowel bar bracket for an airport drainage ditch, which adopts the following technical solution: An airport drainage ditch force transmission rod bracket includes vertical poles and horizontal poles. The vertical poles are arranged vertically. There are at least two vertical poles. The horizontal poles are arranged horizontally. There is at least one horizontal pole. The two ends of the horizontal poles are respectively connected to the two vertical poles. The upright is equipped with a plurality of first mounting seats for mounting force transmission rods. The plurality of first mounting seats are evenly spaced along the length of the upright, and the axis of the upright is perpendicular to the axis of the force transmission rod. The crossbar is equipped with a plurality of second mounting seats for mounting force transmission rods. The plurality of second mounting seats are evenly spaced along the length of the crossbar, and the axis of the crossbar is perpendicular to the axis of the force transmission rod.

[0006] By adopting the above technical solution, a frame structure is formed by at least two vertical poles and at least one horizontal bar. The force transmission rod is fixed by first mounting seats evenly arranged along the length of the poles and second mounting seats evenly arranged along the length of the horizontal bar. The axes of the poles and the horizontal bars are perpendicular to the axis of the force transmission rod, that is, the mounting surface formed by the poles and the horizontal bars is perpendicular to the force transmission rod. The force transmission rod is positioned by the first and second mounting seats, which restricts the displacement and tilt of the force transmission rod, so as to ensure that the axis of the force transmission rod is consistent with the installation position, thereby improving the overall force transmission performance and construction accuracy of the structure.

[0007] Preferably, the two ends of the crossbar are slidably mounted on the two uprights respectively.

[0008] By adopting the above technical solution, the two ends of the crossbar are connected to the upright in a sliding fit manner, so that the crossbar can move along the length of the upright, thereby adjusting the height position of the crossbar and adapting to the installation requirements of the force transmission bar at different elevations.

[0009] Preferably, a connecting seat is fitted onto the upright, and the connecting seat slides relative to the upright; the connecting seat has bolt holes, and bolts are screwed through the bolt holes to abut against the upright, thus fixing the connecting seat onto the upright; both ends of the crossbar are detachably mounted on the connecting seats of the two uprights respectively.

[0010] By adopting the above technical solution, a sliding connecting seat is fitted on the upright, and the position of the connecting seat is fixed by the bolt passing through the bolt hole of the connecting seat and pressing against the upright. The two ends of the crossbar can be detachably installed on the connecting seat, which not only makes the height of the crossbar adjustable, but also ensures the connection stability by locking with bolts. At the same time, the detachable structure is convenient for disassembly, assembly and reuse.

[0011] Preferably, the crossbar is a hollow rod with both ends through it, and the connecting seat is provided with a connecting protrusion, which is inserted into one end of the crossbar and engaged with the crossbar.

[0012] By adopting the above technical solution, the crossbar is designed as a hollow bar with both ends connected. The connecting seat is provided with a connecting protrusion. The structure of inserting the protrusion into the end of the crossbar and snapping it in place strengthens the connection between the crossbar and the connecting seat, while simplifying the assembly and disassembly of the crossbar.

[0013] Preferably, the first mounting seat is sleeved on the upright and slides relative to the upright; the first mounting seat has bolt holes, and bolts pass through the bolt holes and abut against the upright to fix the first mounting seat on the upright; the second mounting seat is sleeved on the crossbar and slides relative to the crossbar, and the second mounting seat also has bolt holes, and bolts pass through the bolt holes and abut against the crossbar to fix the second mounting seat on the crossbar.

[0014] By adopting the above technical solution, the first mounting seat and the second mounting seat are respectively sleeved on the upright and the horizontal bar and can slide relative to each other. By screwing the bolts through the bolt holes and pressing them against the upright, the positions of the first mounting seat and the second mounting seat on the upright and the horizontal bar can be flexibly adjusted and fixed, thereby adapting to different installation spacing and height requirements of the force transmission rod.

[0015] Preferably, both the first mounting base and the second mounting base are fixed with mounting sleeves for fixing the force transmission rod. The mounting sleeve is a cylinder with both ends through it, and the axis of the mounting sleeve is perpendicular to the axis of the upright or crossbar. The mounting sleeve has bolt holes, and the force transmission rod is pressed and fixed after the bolt is screwed through the bolt holes.

[0016] By adopting the above technical solution, a cylindrical mounting sleeve with its axis perpendicular to the upright is fixed on the first mounting base. After the force transmission rod is inserted into the mounting sleeve, the bolts in the bolt holes on the mounting sleeve are tightened, and the mechanical force of the bolts against the force transmission rod is used to firmly fix the force transmission rod and prevent it from shifting or tilting.

[0017] Preferably, the connecting seat is fixed with a mounting sleeve on the side away from the crossbar.

[0018] By adopting the above technical solution, an installation sleeve is also fixed on the side of the connecting seat away from the crossbar, thereby strengthening the support strength of the force transmission rod at the corner of the bracket.

[0019] Preferably, it also includes a base, and the upright is vertically fixed on the base.

[0020] By adopting the above technical solution, the contact area between the bracket and the ground is increased by using the base, and the upright is vertically fixed on the base. By utilizing the stable support characteristics of the base, the overall placement stability of the bracket is improved, and the bracket is prevented from tipping over.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. A frame structure is formed by at least two vertical uprights and at least one horizontal crossbar. First mounting seats evenly distributed along the length of each upright and second mounting seats evenly distributed along the length of each crossbar are used to fix the force transmission rods. The axes of both the uprights and crossbars are perpendicular to the axis of the force transmission rods, meaning the mounting surface formed by the uprights and crossbars is perpendicular to the force transmission rods. The first and second mounting seats are used to position the force transmission rods, limiting their displacement and tilt to ensure that the axis of the force transmission rods is consistent with the installation position, thereby improving the overall force transmission performance and construction accuracy of the structure. 2. A sliding connecting seat is fitted onto the upright, and the position of the connecting seat is fixed by bolts passing through the bolt holes of the connecting seat and pressing against the upright; both ends of the crossbar are detachably installed on the connecting seat, which not only allows the height of the crossbar to be adjusted, but also ensures the connection stability by locking with bolts; at the same time, the detachable structure facilitates disassembly and reuse. 3. The crossbar is designed as a hollow bar with both ends open. The connecting seat is equipped with a connecting protrusion. The structure of inserting the protrusion into the end of the crossbar and snapping it in place strengthens the connection between the crossbar and the connecting seat, while simplifying the assembly and disassembly of the crossbar.

The axis of the crossbars 2 is perpendicular to the axis of the force transmission rods 10.

[0027] In this embodiment, the base 3 is a rectangular plate, which increases the contact area between the bracket and the ground. The upright 1 is vertically fixed on the base 3. The stable support characteristics of the base 3 improve the overall placement stability of the bracket and prevent the bracket from tipping over. Both the upright 1 and the crossbar 2 are cuboid rods with through ends. The upright 1 is generally 2m or 4m long, and the crossbar 2 can be cut according to the dimensions of the trench with different cross sections. In other embodiments, multiple upright 1s and multiple crossbars 2 can be provided as needed.
