Problems solved by technology

Such as asphalt, improved asphalt or various glues and other fillers are easily affected by temperature, and they all have disadvantages such as easy to fall off, break, not durable, not resistant to compression, and poor in practicability. Thermal expansion and contraction of fillers, stress cycle, resulting in poor bonding with concrete, performance is greatly affected by temperature, prone to aging, fracture, falling off, high failure rate, and cannot effectively prevent rainwater, sundries, and pollutants from penetrating Leakage into the ground seriously troubles the management of high-standard enterprises
Especially the anti-seepage floor in the petrochemical industry has stricter requirements on the anti-seepage process of expansion joints, and the maintenance cost of expansion joints obtained by traditional construction techniques is relatively high

Embodiment 1

[0051] The anti-seepage floor expansion joint filling structure, the adhesion and performance of the anti-seepage floor expansion joint joint structure and the floor (concrete) are less affected by temperature, and have the advantages of low failure rate and low maintenance cost ,Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, specifically set to the following structure:

[0052] It includes a channel structure 1 and a sealing rubber strip 2; the channel structure 1 is a metal structure, and the metal structure with an integrated structure is the best. The channel structure 1 has a cavity with a notch at the top. The groove structure 1 has certain elasticity so that when the expansion joint is deformed, its groove cavity can be expanded and compressed adaptively to conform to the deformation of the expansion joint.

[0053] The channel structure 1 in this embodiment is a symmetrical structure, including a bottom plate 1a and a side plate 1b. The left and righ...

Embodiment 2

[0058] This embodiment is further optimized on the basis of the above-mentioned embodiments, further to better realize the present invention, especially adopt the following configuration structure:

[0059] The channel structure 1 also includes a top plate 1c, and the top plate 1c is used to be erected on the top surface of the ground. A horizontal top board 1c is provided on the outer sides of the two side boards 1b, and the top edges of the two side boards 1b are respectively connected to the proximal edges of the top board 1c on the corresponding side. The setting of the top plate 1c further increases the connection area between the channel structure 1 and the floor 4, and the top plate 1c is directly connected to the top surface of the floor 4, which can prevent pollutants such as rainwater from directly falling into the side plate 1b and the wall of the expansion joint The combination can further improve the anti-seepage effect.

[0060] Moreover, the setting of the top ...

Embodiment 3

[0063] This embodiment proposes an expansion joint structure on the basis of the above embodiments, especially adopts the following configuration structure:

[0064] The structure of the expansion joint can adopt the channel structure 1 in Embodiment 1 or Embodiment 2.

[0065] For example, the expansion joint structure includes two floors 4 and the anti-seepage floor expansion joint filling structure in Embodiment 1. An expansion joint 5 is formed between the floors 4 made of two concretes, and the channel structure 1 The small end of the bottom plate 1a is clamped downward in the expansion joint 5, and the outer surface of the side plate 1b is coated with an adhesive layer 3, which is bonded and fixed to the wall of the expansion joint through the adhesive layer 3.

[0066] For another example, the expansion joint structure includes two floors 4 and the anti-seepage floor expansion joint filling structure in Embodiment 2. An expansion joint 5 is formed between the floors 4 m...

Abstract

The invention provides a joint filling structure for an expansion joint of an anti-seepage terrace, an expansion joint structure and an expansion joint construction process and relates to the technical field of expansion joints of terraces, and solves the problem that the bonding property and performance of the joint filling structure for the expansion joint and the terrace in the prior art are affected by temperature greatly. The joint filling structure comprises a straight slot structural member and a sealing joint strip. The straight slot structural member comprises a bottom plate and sideplates, opposite two side edges of the bottom plate are separately connected to the side plates connected to corresponding joint walls of the expansion joint, the bottom plate is an elastic metal structural member, and the two side edges of the bottom plate subjected to a pressure toward the inner side of a slot cavity can move toward the inner side, so that the slot cavity is compressed. The slotcavity formed by the bottom plate and the two side plates is filled with the sealing joint strip. The expansion joint structure of the joint filling structure is constructed by an expansion joint construction process. Compared with the prior art, the joint filling structure has the advantages of relatively low failure rate and maintenance cost.

Description

technical field [0001] The present invention relates to the technical field of floor expansion joints, in particular to an anti-seepage floor expansion joint filling structure, an expansion joint structure using the filling structure, and an expansion joint construction process with the expansion joint structure. Background technique [0002] With the continuous progress of society, the continuous strengthening of social environmental protection awareness, and the gradual improvement of industry standards, industrial enterprises and other industries have gradually increased the requirements for floor expansion joints. [0003] There are many problems in the traditional floor expansion joints, which are as follows: the joint filling process is simple, the options are few, and it does not meet the high standard requirements of the industry. Such as asphalt, improved asphalt or various glues and other fillers are easily affected by temperature, and they all have disadvantages s...
