Description

Technical Field

[0001] The utility model relates to the field of building structures, in particular to a hidden ground deformation joint structure. Background Art

[0002] In existing projects, structural fractures are required for structural settlement, earthquake resistance and other functions. In order to control structural costs and safety, it is crucial to reasonably set the location of structural joints. The location of structural joints is often chosen in the podium, and in actual projects, they will inevitably be set at the junction of the tower and the group of houses. As a weak point in waterproofing, expansion joints often require higher civil engineering requirements and measures.

[0003] As modern buildings have higher and higher requirements for the beauty and practicality of the fifth facade of the roof, the feeling and experience when people walk out of the tower and reach the roof garden (group house roof) cannot be ignored. The threshold of the roof garden is located at the deformation joint of the building. It is crucial to prevent rainwater from leaking into the deformation joint and improve the experience of entering and exiting the roof garden without letting users cross the high threshold. Utility Model Content

[0004] The utility model aims to overcome the above-mentioned defects, solve the hidden danger of rainwater accumulation at deformation joints, solve the drainage measures after rainwater is poured into deformation joints, and solve the problem of achieving a smooth experience of indoor and outdoor waterproof height difference. It takes the most basic "drainage" and "blocking" of drainage as the starting point, cancels the use of stereotyped civil engineering thresholds, and refines the design concept of "organized drainage" to weak drainage points such as deformation joints, providing a hidden ground deformation joint structure.

BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Figure 1 , a schematic diagram of the hidden ground deformation joint structure provided in this embodiment. DETAILED DESCRIPTION

[0034] The present invention can be implemented in a variety of ways and can have various embodiments, so each specific embodiment is illustrated and described in the drawings. However, this does not limit the present invention to a specific implementation, but should be understood to include all changes, equivalents and even substitutes that fall within the concept and technical scope of the present invention.

[0035] like Figure 1 As shown, this embodiment provides a hidden ground deformation joint structure for hiding, waterproofing and sealing the deformation joint, comprising an outer rainwater guide member 100, a deformation joint sealing member and an inner drainage mechanism 410;

[0036] The outer rainwater guide member 100 is in the shape of a sunken guide trough, located at the slope of the deformation joint close to the tower toward the outside, and the end of the guide trough is connected to the drainage pipe to divert the stagnant water that could not be discharged originally.

[0037] The deformation joint sealing member is used to seal the deformation joint in a covering manner, and comprises a cover plate bracket 210 and a cover plate;

[0038] The cover support 210 includes an integrally constructed first cover support frame and a second cover support frame which are arranged vertically. The cover support and its installation with the cover can adopt the existing sealing process and structure of the well body. Since the support is a built-in hanger shape, its edge can consider using glue 10 to achieve the effect of fixing it to the inside of the deformation joint.

[0039] In this embodiment, the cover plate includes a first cover plate 211 and a second cover plate 212;

[0040] The first cover plate 211 is installed on the first cover plate support frame located on the upper layer, flush with the building surface, just closing the deformation joint;

[0041] The second cover plate 212 is installed on the lower second cover plate support frame for double sealing effect.

[0042] A first waterproof layer 310 and a second waterproof layer 320 are vertically arranged in sequence below the cover plate;

[0043] The first waterproof layer 310 and the second waterproof layer 320 are in a pocket shape, just covering the bottom of the cover plate, and are generally fixed to the bearing body on the inner side of the deformation joint by riveting, screwing, etc.

[0044] In the deformation joint, a fireproof belt 20 (made of the same material as the fireproof board used in the building) is also provided according to the general process;

[0045] The inner drainage mechanism includes a drainage groove 400 and a drainage pipe 410;

[0046] The drainage groove 400 is arranged below the inner fire barrier strip under the deformation joint, and is in line with the shape of the fire barrier strip;

[0047] The drain pipe 410 is disposed at the bottom of the drain groove, connected to the drain groove and directly connected to the bottom surface of the floor or disposed in the air, so that the accumulated liquid in the drain groove can be discharged.

[0048] The installation process of the above structure is as follows:

[0049] S1. "Divert a small amount of rainwater". Find a slope outward from the expansion joint near the tower, and use the slope of the roof garden surface layer near the expansion joint to prevent a small amount of rainwater from flowing into the expansion joint.

[0050] S2. "Draining a large amount of rainwater". Set a shallow ditch with a depth of about 120mm near the deformation joint, and lead the shallow ditch into the drainage riser to drain away the rainwater that could not be drained and easily caused water accumulation.

[0051] S3. "Stop water from entering the room". Set up two additional waterproof layers on the plane deformation joint. This article is a common measure

[0052] S4. "Drain the water inside the indoor deformation joint". Install a galvanized drainage riser under the inner fire barrier under the indoor deformation joint.

[0053] Through the above waterproof measures, the reinforced concrete waterproof upturn in traditional technology is eliminated, achieving a smooth experience of entering and exiting indoors and outdoors, and ensuring the beauty and continuity of the facade. At the same time, it can also improve the experience and quality of the roof garden, avoiding the discomfort of the upturned threshold of the expansion joint on the spatial experience and the risk of tripping of personnel. Let the roof garden be truly used, rather than a space that people don't want to go to.

[0054] The above embodiments also have various waterproof measures, and selecting reasonable and appropriate measures can ensure the beauty without reducing the waterproof requirements. It can also be directly modified on the existing structure without incurring additional costs.

[0055] Although the above description is centered on the embodiment, it is only an example and does not limit the present invention. It is clear to those skilled in the art that various modifications and applications not illustrated above can be made within the scope of the essential characteristics of the present embodiment. For example, each component specifically shown in the embodiment can be implemented after being modified. Moreover, various differences related to such modifications and applications should be interpreted as being included in the scope of the present invention as specified in the attached claims.
