Description

Technical Field

[0001] This utility model relates to a SYTD board with a spliced ​​sealing structure. Background Technology

[0002] SYTD (Separate Formwork Decking) floor decking is a composite bottom formwork floor decking developed by Zhongpei Construction. It is a pioneering prefabricated building material and has been gradually put into market application. Due to its high construction efficiency and high forming quality, it is now widely used in prefabricated building floor slabs, large-span steel structure workshops, public buildings (such as stadiums and airports), etc., and is especially suitable for projects that require rapid construction and high flatness requirements.

[0003] However, traditional SYTD boards use simple male and female groove fastening at the splicing points, and the seams rely on manual glue sealing, which has problems such as high grout leakage rate, poor long-term stability, and unsatisfactory sound insulation effect; therefore, a new splicing and sealing structure for SYTD boards is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the existing defects and provide a SYTD board with a spliced ​​sealing structure, so that there are no gaps between the boards and grout leakage is prevented during pouring.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a SYTD board with a splicing and sealing structure, comprising at least two board bodies, including a fastening assembly and a sealing assembly, wherein the fastening assembly is disposed at both ends of the upper end face of the board body; and the sealing assembly is disposed within the splicing seam between two adjacent board bodies.

[0006] Preferably, the board body includes a fiber cement flat plate, a thermal insulation and sound insulation layer, and a steel plate, wherein the upper end face of the fiber cement flat plate is connected to the thermal insulation and sound insulation layer, and the upper end face of the thermal insulation and sound insulation layer is connected to the steel plate.

[0007] Preferably, the fastening assembly includes an upper bent interface plate and a lower bent interface plate, with the left end of the steel plate connected to the upper bent interface plate and the right end connected to the lower bent interface plate.

[0008] Preferably, the sealing component is an elastic sealing strip, which is disposed between two adjacent plates.

[0009] Preferably, the upper and lower bend interface plates of each pair of adjacent plates are connected by a snap-fit ​​joint.

[0010] Preferably, the steel plate is provided with profiled ribs.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The SYTD board with splicing and sealing structure has a bent upper overlapping interface plate at one end of the board body and a bent lower overlapping interface plate at the other end. When two adjacent boards are connected, they are interlocked by the bent upper overlapping interface plate and the bent lower overlapping interface plate. Furthermore, by setting an elastic sealing strip between the two boards, there are no gaps between the boards, and grout leakage is prevented during pouring. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2 A SYTD board with a splicing and sealing structure, comprising at least two board bodies 1, including a fastening assembly and a sealing assembly, wherein the fastening assembly is disposed at both ends of the upper end face of the board body 1; and the sealing assembly is disposed in the splicing seam between two adjacent board bodies 1.

[0018] Specifically, panel 1 includes fiber cement flat plate 2, thermal insulation and sound insulation layer 3, and steel plate 4. The upper end face of fiber cement flat plate 2 is connected to thermal insulation and sound insulation layer 3, and the upper end face of thermal insulation and sound insulation layer 3 is connected to steel plate 4. Profiled ribs are provided on steel plate 4. It exhibits high stability and good sound insulation performance over long-term use.

[0019] Specifically, the fastening assembly includes an upper bent interface plate 5 and a lower bent interface plate 6. The left end of the steel plate 4 is connected to the upper bent interface plate 5, and the right end is connected to the lower bent interface plate 6. The upper bent interface plates 5 and the lower bent interface plates 6 of each pair of adjacent plates 1 are adapted for fastening connection.

[0020] Specifically, the bend of the upper interlocking plate 5 and the bend of the lower interlocking plate 6 has an inclination angle of 12°-18° and an interlocking depth of ≥4mm.

[0021] Specifically, the sealing component is an elastic sealing strip 7, which is disposed between two adjacent plates 1. The elastic sealing strip 7 is embedded in the splicing seam, and a high-elasticity silicone strip (Shore hardness 50±5) is pre-embedded on the side of the plate 1. When the grooves of the two plates 1 are engaged, the silicone strip is compressed by 30%-40%, forming a continuous sealing surface.
