Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering, and particularly relates to an adjustable end-sealing mold for precast concrete box girders. Background Art

[0002] Prefabricated bridge components are widely used in municipal and highway engineering. During the construction of precast box girders, an end-sealing mold is required to seal the ends of the box girders to ensure the quality of concrete pouring. In the above engineering fields, as a common precast component, the end-sealing quality of box girders is directly related to the stability and safety of the entire structure. Most of the existing end-sealing molds have a fixed angle and cannot adapt to box girders with different angles, and need to be customized according to the angle of the box girders, which increases the cost and construction difficulty. At present, precast beam molds are all of standard shapes, specifically including outer molds, inner molds, and right-angle end-head molds, which are suitable for mass production of precast beams with straight-line routes. However, for precast beams produced directly using standard precast beam molds for curved routes, not only will there be conflicts between the ends of adjacent precast beams during erection, but also there may be different degrees of non-compliance and errors in the end-sealing angles of precast beams on different longitudinal sections in the case of a large longitudinal slope of the bridge. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an adjustable end-sealing mold for precast concrete box girders to solve the deficiencies in the prior art.

[0004] To achieve the above purpose, the present invention is implemented through the following technical solutions:

[0005] Provide an adjustable end-sealing mold for precast concrete box girders, which includes an end-sealing box body and an adjusting mechanism. The end-sealing box body is sealed at the end of the precast concrete box girder, and the adjusting mechanism is arranged at the bottom of the end-sealing box body for adjusting the height and angle of the end-sealing box body.

[0006] As the adjustable end-sealing mold for precast concrete box girders, the adjusting mechanism includes a first adjuster, a second adjuster, and an adjusting rod. The first adjuster includes a first adjusting seat, a first screw rod, a long rod nut, and a first fixing seat. The second adjuster includes a second adjusting seat, a second screw rod, and a second fixing seat. The first adjusting seat and the second adjusting seat are fixed on the horizontal plane below the precast concrete box girder. The lower end of the first screw rod is connected to the first adjusting seat, and the upper end is threadedly connected to the long rod nut. The long rod nut is fixed to the bottom of the end-sealing box body through the first fixing seat. The lower end of the second screw rod is connected to the second adjusting seat, and the upper end is fixed to the bottom of the end-sealing box body through the second fixing seat. Both ends of the adjusting rod are rotatably connected to the upper end of the long rod nut and the upper end of the second screw rod respectively.

[0007] As described in the adjustable end-sealing mold for precast concrete box girders, the first screw rod and the second screw rod have a height difference.

[0008] As described in the adjustable end-sealing mold for precast concrete box girders, the end-sealing box body includes a main board and side boards. The main board and the side boards are both rectangular plates. The horizontal width of the main board is greater than the horizontal width of the side boards. The side boards are vertically arranged on one side edge of the main board, and the side boards are attached to the side surface of the precast concrete box girder.

[0009] The beneficial effects of the technical solution of the present invention are as follows:

[0010] 1. Strong versatility: The design of adjustable angle enables this mold to adapt to box girders with different angles, eliminating the need to manufacture separate end-sealing molds for each box girder with a different angle, reducing the types and costs of molds.

[0011] 2. Cost saving: Due to strong versatility, the manufacturing and inventory costs of molds are reduced. At the same time, the time and labor costs for replacing molds during construction are also reduced.

[0012] 3. Improvement of construction efficiency: The use of an adjustable angle end-sealing mold can quickly adjust the mold angle to adapt to different box girders, reducing the adjustment time during construction and improving the construction efficiency.

[0013] 4. Assurance of construction quality: The mold can ensure the accuracy and quality of end-sealing, avoiding construction quality problems caused by mold mismatch.

[0014] 5. Convenient operation: The design of the adjustment mechanism makes the angle adjustment of the mold more convenient and fast, eliminating the need to use complex tools and equipment and reducing the operation difficulty.

[0015] 6. Reduction of waste: The use of an adjustable angle end-sealing mold can avoid material waste caused by angle mismatch and improve the material utilization rate.

[0016] 7. Environmental protection and energy saving: Due to strong versatility, the production and waste of molds are reduced, which is more environmentally friendly and meets the requirements of sustainable development.

[0017] In summary, the use of an adjustable angle end-sealing mold can improve construction efficiency, reduce costs, ensure construction quality, and also has the advantages of environmental protection and energy saving. It is a very practical building construction mold system. BRIEF DESCRIPTION OF THE DRAWINGS
