Description

Technical Field

[0001] The utility model belongs to the technical field of clear water concrete pouring, in particular to a beam and slab formwork structure used for clear water concrete pouring. Background Art

[0002] Fair-faced concrete and exposed concrete formwork are a modernist architectural technique, also known as decorative concrete for its decorative effect. The basic concept is to create a natural look by removing any coating, tile, or stone after the concrete is poured. However, due to concerns about rainwater seepage and deterioration, a waterproof protective film may be applied.

[0003] The supporting panels of existing plain concrete formwork mostly use ordinary wooden boards as the supporting surface. The surface formed by the contact between the wooden boards and the cement is too rough and needs to be repainted by the staff. Secondly, the supporting panel uses multiple secondary back ribs for single-sided support work, and the existing secondary back ribs and supporting panels are generally connected by multiple bolts. A single secondary back rib will be fastened with more than sixteen bolts. This fixing method will greatly increase the work process of the staff during disassembly. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] like Figure 1-5 As shown, the embodiment of the present invention provides a beam-slab formwork structure for casting clear water concrete, which specifically includes a wall support plate body 1, a supporting secondary back rib 2 and an installation component 4 for auxiliary installation of the supporting secondary back rib 2. A wall body 5 cast with cement sand and gravel is provided in the middle of the two wall support plates 1. The wall body 5 can be painted with cement again. The supporting secondary back rib 2 is provided on the side of the wall support plate body 1 away from the wall 5. The installation component 4 is provided on the left and right sides of the supporting secondary back rib 2. A plurality of fastening components 6 are installed through the outer wall of the wall 5. , the outer wall of the supporting secondary back ribs 2 is evenly spaced with supporting main back ribs 3, and the supporting main back ribs 3 are tightly fitted with the supporting secondary back ribs 2 through the fastening components 6. The purpose is that this utility uses clear water board as the wall support plate body 1, which effectively guarantees the strength of the panel and the flatness of the cement contact surface. Secondly, the connection method of the supporting secondary back ribs 2 on the rear side of the wall support plate body 1 is relatively simple, and the use of the mounting component 4 as the connecting part of the overall structure greatly simplifies the process required for its disassembly, thereby effectively saving work time;

[0026] like Figure 1 As shown, the mounting component 4 includes a limit block 401, a connecting plate 402 and a fixing bolt 403. The limit block 401 is symmetrically arranged with the central axis of the secondary back rib 2. The outer wall of the limit block 401 is fixedly connected to the connecting plate 402. The connecting plate 402 is fixedly connected to the wall support plate body 1 through two fixing bolts 403 on the outer wall.

[0027] The specific implementation is as follows:

[0028] The limiting block 401 and the connecting plate 402 are connected by welding, and the connecting plate 402 and the limiting block 401 are fixed to the surface of the wall support plate 1 in advance by two fixing bolts 403. When needed, the supporting secondary back rib 2 can be inserted into the middle of the limiting block 401, and then the bottom limiting block 401 can be fastened to the supporting secondary back rib 2 with screws to complete the installation of the supporting secondary back rib 2. The same can be done when disassembling.

[0029] As an implementation method, the cross section of the supporting secondary back rib 2 is a "convex" structural design, and the supporting secondary back rib 2 and the limiting block 401 complete the locking type limiting work, which is convenient for subsequent disassembly.

[0030] As an embodiment, the wall support plate 1 is a 17 mm thick clear water board. The contact surface of the thick clear water board is relatively smooth, which increases the surface quality of the outer surface of the wall 5.

[0031] like Figure 3 As shown, the fastening component 6 includes a screw 601, a support member 602, a rubber gasket 603 and a fastener 604. The outer walls of both ends of the screw 601 are sleeved with support members 602. The fastener 604 is installed on one side of the support member 602, and the rubber gasket 603 is provided on the other side of the support member 602. The fastener 604 is threadedly connected to the screw 601, and the screw 601 passes through the wall 5.

[0032] The specific implementation is as follows:

[0033] After the supporting secondary back rib 2 of the wall support plate 1 is installed, the supporting main back rib 3 can be installed on the outer wall of the screw 601, and then the rubber gasket 603 and the support member 602 can be installed in sequence. Finally, use a tool to rotate the fasteners 604 at both ends to complete the fastening work, so that the wall support plate 1 fits against the outer wall of the wall 5, thereby making the cement on the contact surface smooth.

[0034] As an embodiment, the fastener 604 is an external hexagonal nut. After the hexagonal nuts at both ends are tightened with a tool, the panel surface can be fitted.

[0035] As an embodiment, a first slot 7 is provided at a position corresponding to the supporting main back rib 3 and the screw 601 , wherein the supporting main back rib 3 can be placed on the screw 601 through the first slot 7 , facilitating subsequent fastening work.

[0036] As an embodiment, a second slotted hole 8 is provided at a position corresponding to the wall support plate 1 and the screw rod 601 . The second slotted hole 8 is a slotted hole reserved by the wall support plate 1 , which facilitates the entry of the screw rod 601 .

[0037] As an embodiment, the bottom mounting component 4 is fixed to the supporting secondary back rib 2 by screws. After the supporting secondary back rib 2 is inserted into the mounting component 4, the bottom end needs to be tightened. When disassembling, only the single screw on the bottom side needs to be removed.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
