Description

Core plate expansion joint structure

Technical Field

The utility model relates to a core, especially a core expansion joint structure.

Background

The core board generally comprises a first face board, a second face board and a sandwich layer arranged between the two face boards, wherein the sandwich layer can be a corrugated core, a honeycomb core or a plurality of hollow pipes arranged at intervals and the like. The core plate has the advantages of high strength, light weight and the like. When the core board is used for beams, columns, floor slabs or roof slabs used for building construction, the core board is usually subjected to thermal expansion and cold contraction due to environmental influence, so that the core board is easy to deform or bend, the strength is reduced, the service life is shortened, and dangers are easily caused when the core board is serious. Therefore, the utility model discloses need to design one kind and can prevent that the core from being heated expend with heat and contract with cold etc. and influence the structure that produces deformation to improve factor of safety.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the above-mentioned not enough of prior art and providing a simple structure, scalable regulation, long service life, core expansion joint structure that factor of safety is high.

The technical scheme of the utility model is that: a core plate expansion joint structure comprises a first face plate, a second face plate and a sandwich layer arranged between the first face plate and the second face plate; the first panel and/or the second panel are provided with concave areas.

Further, the concave area is a groove or a pit.

Further, the concave area is arranged along the width direction of the first panel or the second panel.

Further, the recessed area extends from one end of the first panel or the second panel to the other end.

Furthermore, the concave area is filled with colloid.

Furthermore, the periphery of the core plate is provided with a frame, and the frame is provided with a notch at a position corresponding to the concave area.

Further, the size of the gap is larger than that of the concave area.

Furthermore, colloid is filled between the notch and the concave area.

Further, the concave areas on the first panel and the second panel are oppositely arranged or arranged in a staggered mode.

The utility model has the advantages that: the concave areas are arranged on the face plates of the core plate, so that the core plate can be prevented from being deformed due to expansion caused by heat, contraction caused by cold and the like, the core plate can be freely adjusted, the strength of the core plate is greatly ensured, and the service life and the safety of the core plate are improved; through set up the colloid in the concave area, on the basis that does not influence the flexible regulation of concave area, can also prevent ponding in the concave area.

Detailed Description

The invention will be described in further detail with reference to the drawings and specific examples.

As shown in fig. 1 to 4: a core plate expansion joint structure is characterized in that a core plate 1 comprises a first face plate 11, a second face plate 12 and a sandwich layer 13 arranged between the first face plate and the second face plate; the first panel 11 and/or the second panel 12 are provided with recessed areas 2.

The scheme has the following advantages: because the phenomenon such as expansion, shrink or bending can be produced to the two-layer board of core board after receiving the influence of environment, through set up concave region 2 on at least a panel, no matter the core board receives effort such as pressure, pulling force, all can adjust through the concave region, prevents to produce expend with heat and contract with cold or warp.

In this embodiment, the recessed areas 2 are preferably disposed on both the first panel 11 and the second panel 12, and the recessed areas 2 of the two panels may be disposed oppositely or may be disposed in a staggered manner. The concave area 2 is a groove or a pit structure, and the cross section of the concave area can be square, arc, V-shaped and the like.

In this embodiment, the concave area 2 is provided along the width or length direction of the first panel 11 or the second panel 12. For example, when the core is used as a floor or the like, recessed areas may be provided in the width direction of the face sheets, and one or more recessed areas 2 may be provided on one face sheet, extending from one end of the face sheet to the other end. Or when the core is used for a roof slab, a concave area can be obliquely arranged along the length direction of the panel, and the roof slab is usually obliquely arranged, and the concave area 2 can achieve the slope releasing function.

In this embodiment, can fill the colloid in concave region 2, like structural adhesive or sealed glue etc. because the colloid itself is elastic, can not influence the regulation of concave region, the setting of colloid is in order to prevent ponding in the concave region, the colloid can with panel parallel and level or be close the parallel and level.

In this embodiment, the frame 3 may be disposed at the periphery of the core board to seal the sandwich layer of the core board 1, so as to prevent water or dust from entering the sandwich layer of the core board. The frame 3 and the core plate 1 are welded into a whole. The frame 3 is provided with a notch 4 at a position corresponding to the concave area 2. Because do not set up the breach on the frame of this embodiment, the frame can be given sheltering from the concave area, is unfavorable for the drainage, also can influence the flexible regulation of concave area. Therefore, by providing the notch 4, the free expansion and contraction of the concave section 2 can be ensured, and drainage is also utilized.

In this embodiment, the size of the gap 4 is preferably larger than the size of the recess 2, for example: the shape of breach 4 is square, and the shape of concave area 2 is the arc, and concave area 2 is located in breach 4, and is filled with colloid 5 between breach 4 and the concave area 2. Because colloid 5 has elastic function, can not influence the flexible regulation of concave area, can also reach the connection effect, prevent ponding.

In this embodiment, the sandwich layer of the core board may be a corrugated core, a honeycomb core, or a plurality of hollow pipes arranged at intervals, and the structure of the sandwich layer of the core board is not specifically limited in this embodiment. Preferably, the sandwich panel of the embodiment comprises a plurality of hollow pipes which are arranged at intervals, and the upper end and the lower end of each hollow pipe are connected with the panel in a brazing mode.

In summary, in the present embodiment, the concave areas are arranged on the face plates of the core plate, so that the core plate can be prevented from being deformed due to expansion with heat and contraction with cold, and the like, thereby realizing free adjustment of the core plate, greatly ensuring the strength of the core plate, and improving the service life and safety of the core plate; through set up the colloid in the concave area, on the basis that does not influence the flexible regulation of concave area, can also prevent ponding in the concave area.
