Description

Technical Field

[0001] This utility model belongs to the field of precast slab technology, specifically relating to a double-T slab mold with easily adjustable support legs. Background Technology

[0002] Double-T slabs are precast reinforced concrete slab-beam combined load-bearing components, mainly composed of a wide panel and two narrow, high ribs. They have both lateral and longitudinal load-bearing functions and are widely used in large-span buildings such as industrial plants and logistics warehouses. During the manufacturing process, steel formwork is generally used to form the corresponding shape. Patent application number 202311556369.6 discloses "A Self-Supporting Precast Prestressed Double-T Slab Steel Formwork," specifically disclosing that the double-T mold has a bottom support plate, multiple sections of double-T slab steel formwork are connected end-to-end longitudinally, the bottom of the longitudinal ribs of the double-T slab steel formwork are fixedly connected to the bottom, and each of the two longitudinal ribs is equipped with a self-supporting square steel beam. The front end of the self-supporting square steel beam is connected to the tensioning end positioning steel plate, and the rear end of the self-supporting square steel beam is connected to the fixed end positioning steel plate. This formwork can be moved at any time as needed. However, the large span and wide width of double-T slabs result in long templates, typically 15 meters per section. A set of molds requires two sections connected end to end, making the templates heavy. Ordinary overhead cranes cannot lift the templates directly; the templates must first be separated from the components before they can be lifted. Most templates for large components are fixed structures, making disassembly and assembly extremely time-consuming. To improve production efficiency, it is necessary to improve the existing molds. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the background technology and provide a double T-plate mold with convenient adjustable support legs. This mold can be easily disassembled and assembled, which greatly improves the speed of disassembly and assembly.

[0004] The objective of this utility model is achieved through the following technical solution: A double-T plate mold with easily adjustable outriggers includes a base frame, channel steel supports, tensioning tubes, tensioning connecting plates, panels, fixed stiffeners, movable stiffeners, forward and reverse screws, and tie rod bolts. The base frame is placed horizontally on the ground and has two bottom beams supporting the double-T plate ribs. The channel steel supports are vertically installed on the base frame outside the bottom beams along the contour of the double-T plate, forming a central frame and two outer frames adapted to the contour of the double-T plate. The tensioning tubes are installed on the channel steel supports on both sides of the bottom beams, and the tensioning tubes on both sides of each bottom beam are connected to the same tensioning connecting plate. The three sets of panels are respectively installed on the central frame and the two outer frames. On the frame, multiple fixed stiffeners are installed between the bottom surface of the panel and the top of the middle and outer frames to support the bottom of the panel. Multiple movable stiffeners are set on the back of the panel on both sides of the two bottom beams. Two movable stiffeners near the middle frame are connected to the opposite bottom beams by several tie rod bolts. Several tie rod bolts are installed sequentially on the base frame along the length of the bottom beams. One end of the tie rod bolt is hinged to the end of the movable stiffener, and the other end is connected to the base frame. Two movable stiffeners near the outer frame are connected to the opposite bottom beams by several forward and reverse screw rods. Several forward and reverse screw rods are connected between the corresponding movable stiffeners and the outer frame along the length of the bottom beams.

[0005] Gaps are left between the middle frame and the outer frame and the panel for installing fixed stiffeners and movable stiffeners.

[0006] The channel steel support includes vertically arranged reinforcing channel steel and inclined bracing channel steel, which are fixedly installed on the base frame.

[0007] The beneficial effects of the double T-plate mold with convenient adjustable legs provided by this utility model are as follows: by setting fixed ribs and movable ribs on the panel, and cooperating with forward and reverse screws and tie rod bolts, the ribs can be quickly separated after the double T-plate is formed, avoiding the increase of friction between the ribs and the mold due to the small demolding angle, effectively ensuring the separation speed. At the same time, the mold can be quickly closed for the next round of production. Attached Figure Description

[0014] like Figures 1-4 As shown, the double-T plate mold with easily adjustable outriggers provided in this embodiment includes a base frame 1, a channel steel bracket 2, a tensioning tube 3, a tensioning connecting plate 4, a panel 5, a fixed stiffener 6, a movable stiffener 7, a forward and reverse rotating screw 8, and a tie rod bolt 9. The double-T plate includes a plate surface, ribs, and crossbeams. The presence of two ribs is a significant feature of the double-T plate. The base frame 1 is placed horizontally on the ground. The base frame 1 has two bottom beams 11 supporting the double-T plate ribs. These two bottom beams 11 are the supporting parts for the double-T plate ribs. The channel steel support 2 is vertically installed on the base frame 1 on the outer side of the bottom beam 11 along the contour of the double T-plate, forming a central frame and two outer frames that fit the contour of the double T-plate. To improve the stability of the channel steel support 2, the channel steel support 2 includes vertically arranged reinforcing channel steel 21 and inclined bracing channel steel 22. The reinforcing channel steel 21 and the inclined bracing channel steel 22 are fixedly installed on the base frame 1. The tensioning tubes 3 are installed on the channel steel supports 2 on both sides of the bottom beam 11. The tensioning tubes 3 on both sides of each bottom beam 11 are connected to the same tensioning tube. The tension connecting plate 4 is another important feature of the double-T plate, which is existing technology and will not be described in detail here. The three sets of panels 5 are respectively installed on the middle frame and the two outer frames. Multiple fixed stiffeners 6 are installed between the bottom surface of the panel 5 and the top of the middle frame and the outer frames to support the bottom of the panel 5. Multiple movable stiffeners 7 are set on the back of the panel 5 on both sides of the two bottom beams 11. The two movable stiffeners 7 near the middle frame are connected to the opposite bottom beams 11 by several tie rod bolts 9. A number of tie rod bolts 9 are sequentially installed on the base frame 1 along the length of the bottom beam 11. One end of the tie rod bolt 9 is hinged to the end of the movable stiffener 7, and the other end is connected to the base frame 1. Two movable stiffeners 7 near the outer frame are connected to the opposite bottom beam 11 by a number of forward and reverse rotating screws 8. The number of forward and reverse rotating screws 8 are respectively connected between the corresponding movable stiffener 7 and the outer frame along the length of the bottom beam 11. A gap is left between the middle frame and the outer frame and the panel 5 for installing the fixed stiffener 6 and the movable stiffener 7.

[0015] The method of using this utility model is as follows: During splicing, by rotating the tie rod bolt 9 and the forward and reverse rotating screw 8, the bottom end of the movable stiffening plate 7 is brought closer to the bottom beam 11. At this time, the bottom beam 11 is in close contact with the end of the adjacent panel 5. Then, the tensioning tube 3 and tensioning connecting plate 4 are installed at both ends of the mold, and the prestressed steel strands are threaded through the tensioning connecting plate 4. Subsequently, the reinforcing bars are tied and the embedded parts are installed. After acceptance, concrete is poured. After the concrete has solidified, the prestressed steel strands are cut off on the tensioning connecting plate 4. At the same time, the forward and reverse rotating screw 8 and tie rod bolt 9 are rotated to separate the panel 5 from the rib beam. When hoisting the double T plate, the double T plate can be quickly separated from the mold, which improves the demolding speed. After the double T plate is hoisted away, the mold can be quickly spliced, which greatly improves the preparation work for pouring.

[0016] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present invention should be covered within the scope of protection of the present invention.
