Description
Technical Field
The utility model relates to the field of building construction, in particular to a connecting and mounting structure of a building roof water stop.
Background
The building expansion joint is a construction joint which is arranged at a proper position along the direction of a building or a construction joint of a structure in order to prevent the building component from generating cracks or damages due to the climate temperature change (thermal expansion and contraction). The expansion joint divides building components such as wall, floor, roof (except wood roof) above foundation into two independent parts, so that the building or structure can horizontally expand and contract along the length direction. The expansion joint prevents the house from generating cracks due to climate change. The method comprises the following steps: gaps are reserved at intervals along the length direction of the building, the building is completely disconnected from components above the ground such as a roof, a wall body, a floor and the like, and the foundation of the building is little influenced by temperature change because the foundation of the building is buried underground, and the building is not necessarily disconnected. The width of the expansion joint is generally 20 mm to 30 mm, the joint is filled with heat insulation materials, and the distance between the two expansion joints is definitely regulated in building structure specifications.
A water stop is generally installed at the top of the building expansion joint to prevent water from entering the joint. The water stop adopts the rubber structure, and long-term use rubber can age, needs to change the water stop. The replacement method of the expansion joint water stop belt comprises the following steps: 1. firstly, a constructor uses a spray gun to heat the damaged water stop belt (rubber strip) at high temperature so that the water stop belt (rubber strip) is separated from the d80 expansion joint steel beam automatically; 2. drawing out the damaged water stop belt (rubber strip), and cleaning the garbage sundries and the residual rubber strip in the d80 expansion joint steel beam; 3. uniformly coating grooves on two sides of the steel beam with lubricating grease, and horizontally placing the prepared new rubber strip at the installation position; 4. and embedding the rubber strip into the steel beam groove by using a special tool to finish sealing.
Chinese patent document CN217000218U discloses an expansion joint connection assembly, which solves the problem that the water stop arranged at the expansion joint is inconvenient to maintain after being damaged. The patent utilizes the telescopic members to replace the damaged water stop belt, thereby solving the problem that the water stop belt arranged at the expansion joint is inconvenient to maintain after being damaged. However, in the above-mentioned patent technology, the telescopic member mounting member is disposed at the top of the expansion joint and protrudes from the top surface, and the telescopic deformation portion is in a V-groove structure, so that dirt and rainwater are easily accumulated around the member and in the V-groove, and the member is damaged too early due to erosion.
When the water stop is replaced in the prior art, a new water stop is needed to be plugged into gaps of grooves on two sides of the steel beam, and as the building is exposed to sunlight in long-time wind, the water stop is aged by a section of rear edge and is adhered to the grooves of the steel beam, and the water stop is difficult to clean when being replaced; the girder steel of both sides can have corrosion for a long time, and the new waterstop rubber strip of change like this hardly imbeds in the recess, and then causes the waterstop to change difficulty, problem that the efficiency of construction is low.
The present utility model has been made in view of this application.
