Background

The waffle slab is a tool type template of a reinforced concrete cast-in-place lattice beam floor slab, and in some electronic chip factories, a clean room is the most important part of the electronic chip factories, tens of thousands of pipelines need to penetrate through two and three buildings due to process requirements, and clean air needs to be pressed into the clean room to keep the positive air pressure in the clean room, so a large number of holes are reserved on the floor slab between the two and three buildings, and the waffle slab is needed to be used for forming the holes between the floor slabs. The existing trapezoidal wafer plates comprise trapezoidal cylinders, square bottom plates are arranged below the trapezoidal cylinders, the trapezoidal wafer plates are directly laid on wood plates during use, and then the wafer plates are fixed through self-tapping screws.

Disclosure of Invention

The utility model aims at overcoming the shortcoming that prior art exists, provide one kind and fix a position the connection to the corner junction between per four trapezoidal wafer boards, the location is accurate, connects reliably, guarantees that each trapezoidal wafer board lays the combination positioning mechanism of orderly trapezoidal wafer board.

The utility model discloses the combined positioning mechanism's of trapezoidal waffle board technical scheme is: including trapezoidal barrel, trapezoidal barrel upper end sets up the end cover, sets up four circular barrel on the end cover, and circular barrel's last mouthful sets up the top cap, and trapezoidal barrel's bottom system has square connecting plate, the system has ascending turn-ups all around of connecting plate, and when four adjacent wafer board combination connect, set up the cross locating piece at the connecting plate corner junction of four wafer boards, the cross locating piece includes the cross body, and the body is made all around to decurrent location flange, forms the cross draw-in groove between the location flange, and the turn-ups of cross draw-in groove and four wafer board corner junctions cooperatees.

The utility model discloses a combined positioning mechanism of trapezoidal waffle boards, which is mainly characterized in that upward flanging is arranged around a connecting board at the bottom of a trapezoidal cylinder body, when in construction, a plurality of trapezoidal waffle boards are arranged in sequence, wherein, four adjacent trapezoidal waffle boards at the front, the back, the left and the right are adjacently attached together at the corners of the flanging to form a cross-shaped flanging, then a cross-shaped positioning block is arranged on the cross-shaped flanging, positioning flanges are arranged under the cross-shaped positioning block, a cross-shaped clamping groove is formed between the positioning flanges, the cross-shaped clamping groove is clamped on the adjacent cross-shaped flanging which is attached together, and the inner wall of the positioning flange is blocked on the outer wall of the adjacent cross-shaped flanging which is attached together, thereby, the positioning connection effect is achieved for the four adjacent trapezoidal waffle boards at the front, the back, the left and the right are adjacent trapezoidal waffle, therefore, all the trapezoidal waffle boards are laid neatly, the positioning is accurate, and the connection is reliable.

The utility model discloses the combined positioning mechanism of trapezoidal wafer board, location flange lower extreme inner wall system have the inclined guide face. The inclined guide surface is arranged, so that when the cross-shaped positioning block is inserted into the corner connecting part of the connecting plates of the four waffle boards, the positioning flange is guided to a certain extent, and the positioning flange is inserted more easily. And when two adjacent waffle plates are combined and connected, fixing screws are inserted into the screw holes of the two adjacent waffle plates. Two adjacent waffle boards are fixed by fixing screws, so that the fixing and positioning effects can be further achieved.

Detailed Description

The utility model relates to a combined positioning mechanism of trapezoidal wafer board, as shown in fig. 1-fig. 3, including trapezoidal barrel 1, trapezoidal barrel upper end sets up end cover 2, sets up four circular barrel 3 on the end cover, and circular barrel's the suitable for reading sets up top cap 4, and square connecting plate 5 has been made to trapezoidal barrel 1's bottom system, system all around of connecting plate 5 has ascending turn-ups 6, and when four adjacent wafer boards combined connection, set up cross locating piece 7 in 5 corner junctions of the connecting plate of four wafer boards, the cross locating piece includes cross body 8, and system all around of body has decurrent locating flange 9, forms cross draw-in groove 10 between the locating flange, and the cross draw-in groove cooperatees with the turn-ups 6 of four wafer board corner junctions. The periphery of a connecting plate 5 at the bottom of a trapezoidal barrel body 1 is provided with upward flanges 6, when in construction, a plurality of trapezoidal waffles are sequentially placed, wherein four adjacent trapezoidal waffles at the front, the rear, the left and the right are adjacently attached together at the corners of the flanges 6 to form a cross-shaped flange, then a cross-shaped positioning block 7 is arranged on the cross-shaped flange 6, positioning flanges 9 are arranged below the cross-shaped positioning block, a cross-shaped clamping groove 10 is formed between the positioning flanges, the cross-shaped clamping groove is clamped on the adjacent cross-shaped flanges attached together, the inner walls of the positioning flanges 9 are blocked on the outer walls of the adjacent cross-shaped flanges attached together, so that the positioning connection effect is achieved on the four adjacent trapezoidal waffles at the front, the rear, the left and the right are adjacent, the cross-shaped positioning blocks 7 are sequentially arranged on every four adjacent trapezoidal waffles, and all, the positioning is accurate and the connection is reliable. The inner wall of the lower end of the positioning flange 9 is provided with an inclined guide surface 11. The inclined guide surface 11 is arranged, so that when the cross-shaped positioning block 7 is inserted into the corner connecting part of the connecting plates 5 of the four waffle boards, the positioning flange 9 is guided to a certain extent, and the positioning flange is easier to insert. The turnup 6 is provided with screw holes 12, and when two adjacent waffle boards are combined and connected, fixing screws 13 are inserted into the screw holes of the two adjacent waffle boards.
