Description

Technical Field

[0001] This invention relates to the field of rail transit construction technology, specifically to a wheel-rail type magnetic suction formwork. Background Technology

[0002] The traditional construction method of double-block ballastless track bed adopts a manual in-situ assembly line operation mode. During the conversion of the formwork engineering work surface, it is necessary to collect and organize the formwork, transport and install the traveling rails, and install the formwork, which makes the construction process complicated and the connection between the processes poor.

[0003] Furthermore, in actual construction, traditional formwork is connected to the bridge deck via struts and tie rods. This construction and installation method requires a large number of tie rods and bolt connections, which occupy a large space and can easily cause problems such as a chaotic work surface and complicated installation of struts and tie rods, thereby affecting the overall construction efficiency and making it difficult to quickly advance the construction surface on the construction beam.

Adjacent side formwork is assembled by plug-in connectors. Multiple sets of installation grooves are provided on the outer end face of the side formwork at intervals. A bracket is installed in the installation groove in a socket-type manner. The bracket is composed of vertically connected upright plates and support plates. The upright plates are connected to the installation grooves, and the support plates are fixedly pressed onto the construction beam surface. A rail groove is provided at the upper end of the support plate, and a steel rail is installed on the rail groove. The steel rail is fixedly installed on the support plate by fasteners.

The upright plate is placed in the mounting slot, and the upright plate is provided with insert plates on both sides that cooperate with the card slots.

[0009] Preferably, the width of the rail groove is greater than the width of the rail, a pad for supporting the rail is provided at the middle of the upper end of the rail groove, and fasteners for fixing the rail are provided on both sides of the rail groove.

[0010] Preferably, a through hole is provided through the track groove, and an installation bolt is vertically installed in the through hole. The lower end of the installation bolt is fixed to the construction beam surface through a drilled hole. The fastener includes a gauge baffle, a spring strip, a flat bottom washer, and a nut. The gauge baffle, the spring strip, and the flat bottom washer are sequentially fitted onto the installation bolt.

[0011] Preferably, the front and rear ends of the rail groove are provided with chamfered surfaces, one side of the gauge baffle abuts against the lower side wall of the rail, and the other side of the gauge baffle is provided with a baffle base that fits against the inner wall of the rail groove, with the upper end of the baffle base fitting against the inclined surface of the chamfered surface.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention effectively solves problems such as poor connection between work surface transition processes and low mechanization costs in formwork engineering by incorporating a shared rail design for formwork and steel rails; the interlocking structure design of formwork and steel rails enables rapid installation and disassembly between the formwork and steel rails; and the connection structure between formwork and steel rails eliminates the traditional formwork fixing method of using struts and tie rods to connect to the beam surface, thus solving the problem of work surface chaos caused by tie rods and struts.

[0023] Please see Figures 1 to 5 The present invention provides a technical solution:

[0024] Example 1: A wheel-rail type magnetic suction formwork, the magnetic suction formwork is composed of multiple sets of side formwork 1 connected by magnetic suction device 5, adjacent side formwork 1 are assembled by plug-in parts 6, multiple sets of installation grooves 10 are provided on the outer end face of the side formwork 1 at intervals, brackets 4 are installed in the installation grooves 10 in a socket-type manner, the brackets 4 are composed of vertically connected upright plates 41 and support plates 42, the upright plates 41 are connected to the installation grooves 10, the support plates 42 are fixedly pressed onto the construction beam surface, the upper end of the support plate 42 is provided with a rail groove 44, a steel rail 7 is installed on the rail groove 44, and the steel rail 7 is fixedly installed on the support plate 42 by fasteners 8.

[0025] The design of the steel rail 7 and bracket 4 enables the assembly and connection of the steel rail 7 and the formwork system. The overall stability of the formwork system is achieved by bolting the bracket 4 to the bridge deck. The bracket 4 and the formwork adopt a socket connection to achieve a quick connection between the formwork and the bracket 4. The bracket 4 and the steel rail adopt a fastener connection to achieve a quick assembly between the bracket 4 and the steel rail 7. Through the connection structure between the formwork and the steel rail 7, the traditional formwork fixing method of using struts and tie rods to connect to the beam surface is eliminated, solving the problem of the chaotic working surface caused by tie rods and struts.

[0026] Example 2: Based on Example 1, in order to achieve precise positioning and installation of bracket 4, a first clamping plate 2 and a second clamping plate 3 fixed on the side template 1 are respectively provided on both sides of the mounting groove 10. The first clamping plate 2 and the second clamping plate 3 are parallel to each other and are staggered vertically. The first clamping plate 2 and the second clamping plate 3 both extend to the outside of the side template 1, and the lower end of the first clamping plate 2 and the second clamping plate 3 are provided with a slot 9. The upright plate 41 is placed in the mounting groove 10, and the two sides of the upright plate 41 are provided with insert plates 43 that cooperate with the slot 9.

[0027] By setting the mounting slot 10 and the upright plate 41 to cooperate, the installation position of the bracket 4 is limited, and the bracket 4 is installed in a limited position by using the slot 9 and the insert plate 43.

[0028] Example 3: Based on Example 2, the width of the rail groove 44 is greater than the width of the rail 7. A pad 47 supporting the rail 7 is provided in the middle of the upper end of the rail groove 44. Fasteners 8 for fixing the rail 7 are provided on both sides of the rail groove 44. A through hole 87 is provided through the rail groove 44. A mounting bolt 81 is vertically installed in the through hole 87. The lower end of the mounting bolt 81 is fixed to the construction beam surface through a drilled hole. The fastener 8 includes a gauge baffle 86, a spring strip 83, a flat bottom washer 84 and a nut 82. The gauge baffle 86, the spring strip 83 and the flat bottom washer 84 are sequentially fitted onto the mounting bolt 81.

[0029] By using fasteners 8 and mounting bolts 81, the bracket 4 is fixed to the construction beam surface, while the rail 7 is also fixedly installed.

[0030] The front and rear ends of the rail groove 44 are provided with chamfered edges 46. One side of the gauge baffle 86 abuts against the lower side wall of the rail 7. The other side of the gauge baffle 86 is provided with a baffle base 85 that fits against the inner wall of the rail groove 44. The upper end of the baffle base 85 fits against the inclined surface of the chamfered edge 46. A triangular reinforcing plate 45 is provided at the vertical connection between the upright plate 41 and the support plate 42. The elastic strip 83 is pressed against the upper end of the lower horizontal plate of the rail 7. The upper end of the flat bottom washer 84 is tightened and fixed by the nut 82 on the upper end of the mounting bolt 81 through threaded rotation.

[0031] The position of the rail 7 on both sides is limited by the gauge baffle 86 to prevent deviation. The lateral support strength is increased by setting the chamfered surface 46 and the baffle base 85 to prevent squeezing deformation. The support strength of the bracket 4 is improved by the reinforcing plate 45, so that the rail 7 can be fixed and accurately installed on the bracket 4 under the limiting and pressing of the elastic bar 83.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
