Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of track beam construction, particularly relates to a construction formwork for track beam. BACKGROUND

[0002] In the wharf yard area, a track beam is usually set in advance to facilitate the subsequent installation of the gantry crane track. The construction of the track beam usually precedes the large-scale construction of the wharf yard, and the construction process involves the erection of a formwork on a concrete cushion. Due to the design feature of the track beam, which is narrow at the top and wide at the bottom, it can be divided into a narrow upper part and an enlarged lower part, and a transition section between the narrow upper part and the enlarged lower part, which has a concrete surface facing upward, and a cover form is used to form the transition section. A track groove is provided at the top of the track beam, and a top pressing formwork is provided at the bottom of the track groove to form the bottom surface of the track groove.

[0003] The cover form and the top pressing formwork in the formwork system both serve to cover the concrete from above to ensure that the concrete can solidify according to the predetermined shape.

[0004] However, the current technology faces a significant problem: the presence of the cover form or the top pressing formwork hinders the vibration of the concrete below the formwork by the vibrating equipment. This not only affects the compactness and strength of the concrete, but also, in the area where the concrete is in contact with the bottom surface of the cover form or the top pressing formwork, the air bubbles generated during the vibration of the concrete tend to accumulate there and are difficult to expel. This air bubble retention phenomenon often leads to surface defects such as honeycomb pitting and poor flatness of the concrete, seriously affecting the overall quality and aesthetics of the track beam structure. SUMMARY

[0005] The utility model aims at overcoming the problems in the prior art that the cover form or the top pressing formwork in the track beam formwork hinders the vibration of the concrete below the formwork by the vibrating equipment, and the air bubbles generated during the vibration process tend to accumulate on the bottom surface of the cover form or the top pressing formwork, leading to surface defects such as honeycomb pitting and poor flatness of the concrete, and provides a construction formwork for track beam.

[0006] The utility model provides a construction formwork for track beam, which comprises:

[0007] A first side plate is located on both sides of the enlarged lower part of the track beam to be poured, and is used to form the enlarged lower part of the track beam to be poured. The bottom of the first side plate is mounted on the foundation cushion.

[0008] A second side plate is located on both sides of the narrow upper part of the track beam to be poured, and is used to form the narrow upper part of the track beam to be poured.

[0009] A cover plate is connected to the top of the first side plate and the bottom of the second side plate, and is used to form a transition section of the track beam to be cast.

[0010] A groove side plate is located on the inner side of the second side plate, and is located on both sides of a track groove of the track beam to be cast, and is used to form groove walls on both sides of the track groove.

[0011] The bottom of the track groove is not provided with a pressing top formwork.

[0012] During casting, the concrete is first cast to the window elevation position, the concrete cast in the lower enlarged part of the track beam is vibrated through the window, then the elevation of the concrete is continuously cast to the bottom of the groove side plate, i.e. the bottom of the track groove, and then the concrete cast in the upper narrow part of the track beam is vibrated by extending the vibrating device between the groove side plates, and before the concrete at this position is initially set, the concrete on both sides of the track groove is continuously cast to form the side walls of the track groove.

[0013] The utility model provides a construction formwork for track beam, the first side plate and the second side plate are all used to form the lateral formwork of the track beam to be cast. The bottom of the first side plate is installed on a foundation cushion layer, and the foundation cushion layer can be directly used as the bottom formwork of the track beam to be cast. The cover plate is used to connect the top of the first side plate and the bottom of the second side plate.

[0014] The window is formed in the cover plate, the vibrating device can vibrate the concrete cast in the lower enlarged part of the track beam through the window, and the air bubbles in the vibrated concrete can be discharged through the window, so that the air bubbles cannot accumulate at the bottom of the cover plate, thereby reducing the appearance defects such as honeycomb surface and poor flatness of the concrete surface at this position.

[0015] The groove side plate is used to shape the side walls of the track groove, and the bottom of the track groove is not provided with a pressing top formwork. Therefore, the vibrating device can extend into the track groove to vibrate the concrete cast in the upper narrow part of the track beam.

[0016] By opening the window on the cover plate and arranging the groove side plates only on both sides of the track groove, the appearance defects such as honeycomb, poor flatness and the like of the concrete surface at the bottom of the cover plate and the track groove can be reduced.

[0017] The shape and size of the window are not particularly limited, as long as the vibrating device can be inserted into the lower enlarged part of the track beam through the window to perform the concrete vibrating operation. The shape of the window can be circular, rectangular or square.

[0018] The groove side plate can be connected with the second side plate through a connecting piece. For example, the side surface of the groove side plate can be connected with the side surface of the second side plate through the connecting piece, or the bottom of the groove side plate can be connected with the side surface of the second side plate through the connecting piece, or the top of the groove side plate can be connected with the top of the second side plate through the connecting piece.

[0019] Preferably, a window sash matching the window is arranged on the cover plate, and the window sash can make the window in a closed state or an open state. The window sash is used to cover the window. When the window sash is in the open state, the concrete can be poured into the lower enlarged part of the track beam through the window, and when the concrete is poured to the position of the window, the vibrating device can be used to vibrate the concrete in the lower enlarged part of the track beam through the window, and the air bubbles in the vibrating concrete can be discharged outward through the window to avoid the air bubbles accumulating under the cover plate. After the concrete in the position is vibrated, the window sash can be closed to cover the window, and then the concrete of the track beam can be continuously poured. The window sash in the closed state can avoid the concrete overflowing from the window during the continuous pouring of the concrete, and the concrete pouring can be accelerated without waiting for the concrete under the cover plate to be close to initial setting, so that the construction efficiency is improved.

[0020] The window sash and the cover plate can be connected through a buckle or be rotatably connected through a bolt.

[0021] Preferably, the window sash is provided with a first bolt and a second bolt at opposite ends, the window sash is rotatably connected with the cover plate through the first bolt, and the second bolt is used to lock the window sash and the cover plate when the window sash makes the window in the closed state.

The fixing rod can also serve as a connection between the second side plates on the left and right sides.

[0023] Preferably, the outer side of the first side plate is provided with an ear plate, and the ear plate is connected with the base cushion layer through a pull rod. The main function of the pull rod is to fix the first side plate on the base cushion layer, so as to prevent the upward force generated by the extrusion of flowing concrete during concrete pouring from acting on the cover plate, which may cause the cover plate and the first side plate to move upward. The setting of the pull rod aims to effectively control the first side plate and ensure that it will not move upward during concrete pouring.

[0024] Preferably, the second side plate is provided with a first pair of pull screws and a second pair of pull screws, the first pair of pull screws is located above the second pair of pull screws, and the first side plate is provided with a third pair of pull screws.
