Problems solved by technology

[0002] In the production process of traditional bridge prefabricated beams and slabs, the steel molds used in the vertical formwork range from more than 100 kilograms to four to five tons. Manual assembly is very laborious. Generally, gantry cranes and manual methods are used to assemble the formwork, but the efficiency It is still not high, and the speed is very slow. According to the statistics of this construction technology, a bridge beam slab production line with an annual production capacity of 5,000 cubic meters of concrete, with the assistance of gantry cranes, needs to be equipped with 8 manual assembly formworks, and only 5 can be assembled in a day. Set of templates
After assembling the formwork, it is necessary to manually measure the size, adjust the angle, and level it every time. Therefore, it is impossible to guarantee that the formwork assembled is exactly the same every time, and the quality of the produced products is also uneven.
It has the following deficiencies: 1. Low production efficiency, slow speed, labor-intensive and time-consuming; 2. Difficult to guarantee quality; 3. High labor costs; 4. Restricting the development of the industry

Embodiment 1

[0011] Embodiment 1: refer to Figure 1~3 . A special forming mold for T-shaped prefabricated beam slabs, including a base 4, on which is provided a T-shaped formwork for making T-shaped prefabricated beams and slabs, the T-shaped formwork consists of two sets of side formworks 2 and two sets of end formworks 1, two sets of side formworks 2 are placed symmetrically on the left and right sides of the upper end of the base 4, the two sets of end formworks 1 are respectively connected to the front and rear ends of the two sets of side formworks 2, and the base 4 is provided with a number of side formworks 2 convenient for both sides As well as two sets of guide rails 4a for the outward sliding of the end formwork 1, the lower ends of the side formwork 2 and the lower ends of the end formwork 1 are respectively provided with guide grooves that match and connect with the guide rails 4a, that is, the side formwork 2 and the end formwork 1 are respectively along the guide rails at th...

Embodiment 2

[0012] Embodiment 2: refer to Figure 1~3 . After using this mold, the same production line only needs to be equipped with a part-time mechanical operator, and at least 60 sets of templates can be assembled a day, which not only saves labor, but also greatly improves work efficiency; , resulting in large errors in the angle and size of the beams and slabs; the possibility of manual constraints on the mass production process is also reduced.

[0013] In this set of molds, after the initial setting of the concrete, the side formwork and end formwork are opened, and then covered with thermal insulation tarpaulin for steam curing. After 72 hours, the prefabricated beam slab can be removed from the base.

Abstract

The invention relates to a special forming mold for a T-shaped precast beam plate, comprising a base, wherein the base is provided with a T-shaped mold frame for manufacturing the T-shaped precast beam plate, the T-shaped mold frame consists of two groups of side templates and two groups of end templates, the two groups of side templates are respectively symmetrically arranged at the left side and the right side at the upper end of the base in parallel, the two groups of end templates are respectively connected with and arranged at the front end and the back end of the two groups of side templates, the base is provided with a plurality of guide rails which are convenient for the two groups of side templates and the two groups of end templates to slip outwards, the lower end of each side template and the lower end of each end template are respectively provided with a guide groove which is matched and connected with each guide rail, a plurality of electric push rods are arranged at the outer sides of the side templates and the outer sides of the end templates on the base, the screw rod end of each electric push rod at the outer side of each side template is connected with each side template, the screw rod end of each electric push rod at the outer side of each end template is connected with each end template, and the stand end of each electric push rod is fixedly connected with the base.

Description

technical field [0001] The invention relates to a prefabricated beam slab forming die, in particular to a T-shaped prefabricated beam slab special forming die. Background technique [0002] In the production process of traditional bridge prefabricated beams and slabs, the steel molds used in the vertical formwork range from more than 100 kilograms to four to five tons. Manual assembly is very laborious. Generally, gantry cranes and manual methods are used to assemble the formwork, but the efficiency It is still not high, and the speed is very slow. According to the statistics of this construction technology, a bridge girder slab production line with an annual production capacity of 5,000 cubic meters of concrete, with the assistance of gantry cranes, needs to be equipped with 8 manual assembly formworks, and only 5 can be assembled in a day. Set of templates. After assembling the formwork, it is necessary to manually measure the size, adjust the angle, and level it each tim...
