Description

Technical Field

[0001] This utility model relates to the field of construction technology of platform structure slabs in rail transit engineering, specifically to an adjustable post-pouring device for platform structure slabs. Background Technology

[0002] In the construction of station platform structures for rail transit projects, train tracks are usually installed after the construction of the platform structure slab in the adjacent track area is completed. However, in practice, both the platform structure slab and the train tracks have construction errors. Only after the train tracks are completed and the clearance inspection of the platform structure slab in the adjacent track area is carried out can the encroaching parts (excess parts extending outward) of the platform structure slab be effectively identified. Then, personnel are organized to remove the encroaching parts. Currently, to avoid encroaching parts at the slab edges, the platform structure slab in the adjacent track area is usually constructed using two methods: staged pouring and setting a 1-2cm allowance at the slab edge. Staged pouring can effectively avoid encroachment and secondary removal, but it requires the erection of formwork supports in the track area, which is inconvenient and inefficient, and is prone to encroachment due to formwork construction deviations. Setting a 1-2cm allowance at the slab edge is difficult to control through the existing formwork, and therefore cannot guarantee the effective avoidance of encroachment and secondary removal. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an adjustable post-pouring device for rail-mounted structural slabs that is highly adaptable, avoids edge encroachment, reduces the trouble of secondary chiseling, is convenient to construct as a whole, and has high construction efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An adjustable post-casting device for a track-adjacent structural slab includes a template and a pre-cast track-adjacent structural slab. At least two rows of anchor cylinders are pre-embedded within the track-adjacent structural slab, spaced apart along its length. Each anchor cylinder is threaded with a screw rod, the outer end of which extends from the track-adjacent side of the structural slab and is provided with a support seat. The template and each support seat have corresponding hook plates, which are hooked onto each support seat. The bottom of the template has a base plate, and an upward-opening post-casting groove is formed between the template, the base plate, and the track-adjacent side of the structural slab.

[0006] As a further improvement to the above technical solution:

[0007] The corresponding hook plate and support base can be detached and fixed by fasteners.

[0008] The support is square, and the hook plate has a hook groove with an opening facing downwards. The hook groove is hooked onto the top of the support.

[0009] The locking device is a locking screw.

[0010] The rail-adjacent structural plate has a panel attached to its rail-adjacent side. The panel is fixedly connected to the anchor cylinder, and the screw passes through the panel. The base plate is detachably connected to the panel.

[0011] The bottom of the panel is provided with a base plate, and the base plate is provided with a slot. The base plate is inserted into the slot and fixed to the base plate by a locking member.

[0012] The base plate is attached to the bottom surface of the adjacent rail structure plate, and the base plate is provided with anchor bars, which are pre-embedded in the adjacent rail structure plate.

[0013] The outer side of the panel is provided with multiple seam bonding pieces.

[0014] The template is supported by stiffening ribs below the support base, and the portions of each row of screws located in the post-cast groove are connected by steel rods. The outer wall of the anchor cylinder is provided with external threads.

[0015] The post-cast trench contains edge concrete.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] The construction process of the adjustable post-pouring device for the track-adjacent structural slab of this utility model is as follows: First, the track-adjacent structural slab is poured, and before pouring, at least two rows of anchor cylinders are pre-embedded in the track-adjacent structural slab at intervals along the length direction, so that the outer end face of the anchor cylinder is aligned with the track-adjacent side of the track-adjacent structural slab; after the train track construction is completed, the track-adjacent structural slab (also known as the track-adjacent platform structural slab) is checked for clearance, and the width of the edge concrete to be increased on the track-adjacent side of the track-adjacent structural slab is measured; then, threaded rods are connected to each anchor cylinder, and the extension length of the outer end of each threaded rod from the track-adjacent side of the track-adjacent structural slab is adjusted to meet the requirement of increasing the width of the edge concrete; each hook plate on the template is hooked one by one onto the support seat at the outer end of each threaded rod, and a base plate is set at the bottom of the template, so that an upward-opening post-pouring groove is formed between the template, the base plate and the track-adjacent side of the track-adjacent structural slab; concrete is poured into the post-pouring groove to form the edge concrete. Firstly, by adjusting the extension length of each screw from the rail-side of the adjacent structural slab, the required width of the edge concrete can be increased, demonstrating strong adaptability. Secondly, the adjacent structural slab is poured first, and then the edge concrete is poured according to actual needs, avoiding encroachment on the edge and reducing the trouble of secondary chiseling. Thirdly, the overall structure is easy to construct and has high construction efficiency. Fourthly, the formwork is fixed to the adjacent structural slab by screws, making formwork erection convenient. Attached Figure Description
