Description

Technical Field

[0001] This utility model belongs to the field of construction technology of slab track base plate, specifically relating to slab track base plate template. Background Technology

[0002] In the field of high-speed railway construction, the construction of CRTSIII type slab track base plate is a critical link. The construction quality of expansion joints directly affects the track slab laying and the safety and stability of subsequent train operation. Currently, during the construction of base plates, expansion joints are generally made using insert plates with a length slightly shorter than the width of the base plate, which are clamped onto the base plate template using G-type clips. However, during the concrete pouring process, factors such as concrete compression and workers stepping on the plates can easily cause disturbance, resulting in the expansion joint becoming skewed and unable to guarantee straightness. This not only affects the laying accuracy of the track slab but may also pose safety hazards for subsequent track operation and affect track slab laying. Therefore, this utility model proposes a slab track base plate template. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figures 1 to 4 This is an embodiment of the present utility model, which provides the following technical solution: a slab-type ballastless track base plate template, including...

[0023] Two side steel molds 1 are provided. Each side steel mold 1 is composed of a base plate side mold top steel plate 11, a base plate side mold bottom steel plate 12, a base plate side mold panel 13, and a base plate side mold template stiffener 14 welded together. Multiple base plate side mold template stiffeners 14 are welded and fixed between the base plate side mold top steel plate 11, the base plate side mold bottom steel plate 12, and the base plate side mold panel 13. The base plate side mold top steel plate 11 and the base plate side mold bottom steel plate 12 are steel plates with a length of 2810 mm, a width of 60 mm, and a thickness of 6 mm. The base plate side mold panel 13 is a steel plate with a length of 2812 mm, a width of 250 mm, and a thickness of 5 mm. The base plate side mold template stiffener 14 is a steel plate with a width of 60 mm and a thickness of 5 mm.

[0024] And the square steel 3 connecting the two side steel molds 1;

[0025] And a base plate expansion joint insert 21 is set between the two side steel molds 1 and behind the square steel 3. The base plate expansion joint insert 21 is a steel plate with a length of 2940mm, a width of 290mm and a thickness of 5mm. A 40mm upper tube 22 is welded and fixed to the top surface of the base plate expansion joint insert 21, and the upper tube 22 is located at the top of the square steel 3 and the side steel mold 1.

[0026] In this embodiment, preferably, a bolt connection assembly is provided between the square steel 3 and the side steel mold 1, and the bolt connection assembly includes a mounting bolt 41 and a mounting nut 42.

[0027] In this embodiment, preferably, the surface of the base plate side formwork template rib 14 is provided with two bolt holes A141 for the installation bolts 41 to pass through. Both ends of the square steel 3 are provided with bolt holes B31 for the installation bolts 41 to pass through. This allows the square steel 3 to be connected between the two side steel molds 1 by the installation bolts 41 and the installation nuts 42, thus achieving a combined connection between the two side steel molds 1. In actual construction, the base plate is composed of two side steel molds 1. The square steel 3 is used to break the two side steel molds 1 at the expansion joint position. The width of the square steel 3 is smaller than the width of the template. The two side steel molds 1 and the square steel 3 are connected by the installation bolts 41 and the installation nuts 42. It is used with a 2940mm long and 5mm thick base plate expansion joint insert 21. The base plate expansion joint insert 21 and the expansion joint foam board are sandwiched between the two side steel molds 1. This ensures that the expansion joint will not be disturbed during construction, thus achieving the purpose of ensuring that the expansion joint is vertical and straight.

[0028] In this embodiment, preferably, an auxiliary installation structure is also included, which is disposed between the square steel 3 and the side steel mold 1.

[0029] In this embodiment, preferably, the auxiliary installation structure includes cylindrical inserts 32 welded and fixed to both sides of the square steel 3, and insertion holes 142 opened on the surface of the side mold template rib plate 14 of the base plate for the cylindrical inserts 32 to pass through. When the square steel 3 and the side steel mold 1 are connected, the cylindrical inserts 32 can be inserted into the insertion holes 142 to achieve preliminary auxiliary positioning when the two are connected, which facilitates the quick alignment of bolt holes B31 and bolt holes A141 and improves connection efficiency.

[0030] In this embodiment, preferably, the auxiliary installation structure further includes an auxiliary limiting structure 33. The auxiliary limiting structure 33 is disposed on the cylindrical insert 32. The auxiliary limiting structure 33 includes an inner groove 331 formed on the top surface of the cylindrical insert 32. A spring 332 and a right-angled trapezoidal telescopic block 333 are installed in the inner groove 331. The right-angled trapezoidal telescopic block 333 is movably installed in the inner groove 331 by the spring 332. The top of the right-angled trapezoidal telescopic block 333 extends through to the top of the cylindrical insert 32. The distance between the top of the right-angled trapezoidal telescopic block 333 and the square steel 3 is greater than the thickness of the side mold template rib 14 of the base plate. This ensures that when the cylindrical insert 32 passes through the insertion hole 142, the top of the right-angled trapezoidal telescopic block 333 will be first... The cylindrical insert 32 is inserted into the inner groove 331, allowing it to pass smoothly through the insertion hole 142. When the square steel 3 is in contact with the base plate side mold template rib 14, the top of the right-angled trapezoidal telescopic block 333 will pop out under the push of the spring 332 and lock onto the inner surface of the base plate side mold template rib 14. This provides an auxiliary connection between the square steel 3 and the base plate side mold template rib 14, preventing unnecessary separation between the square steel 3 and the side steel mold 1 during the subsequent bolt connection process. This facilitates installation. When the installation bolts 41 and installation nuts 42 are tightened, the base plate side mold template rib 14 and the square steel 3 will only be pressed tighter, and the right-angled trapezoidal telescopic block 333 will not affect the normal connection of the installation bolts 41 and installation nuts 42.

[0031] In this embodiment, preferably, the bottom end of the spring 332 is fixed to the bottom surface of the inner groove 331, and the top end of the spring 332 is fixedly connected to the bottom end of the right-angled trapezoidal telescopic block 333 to ensure the installation stability of the right-angled trapezoidal telescopic block 333.

[0032] Although embodiments of the present invention have been shown and described (see the detailed description above), 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 present invention, the scope of which is defined by the appended claims and their equivalents.
