Description

Technical Field

[0001] The utility model belongs to the technical field of deformation joint construction, in particular to a temporary roof deformation joint structure suitable for the synchronous implementation of cover plates in TOD (Transit Oriented Development) development. Background Art

[0002] Vehicle base TOD development and station-city integrated TOD development refer to the use of vehicle bases, stations or property integrated roofs as property development sites for secondary development. Affected by various factors, there is a time difference in the construction processes of vehicle bases or station-city integration, and it is impossible to implement them synchronously. Therefore, it is necessary to reserve construction conditions for secondary development during the construction of vehicle bases or stations, such as the simultaneous implementation of roofs of vehicle bases or stations. Such roofs are generally temporary roofs. As development land, temporary roofs are temporarily used as bearing roofs of vehicle bases or stations before the construction of secondary development, and have certain storage functions. Such roofs generally reserve deformation joints and add concrete anti-ridges on both sides of the deformation joints. The deformation joints are used to ensure that the roof is not damaged under the action of temperature stress, and the concrete anti-ridges are used to increase the overall height of the deformation joints. During the construction of secondary development, the above-mentioned concrete anti-ridges need to be broken, and the temporary roof at this time is used as the construction site for secondary development. After the completion of the secondary development construction, the temporary roof after construction is transformed into an indoor roof. The indoor roof is used as the floor of the property development and no longer has the function of a temporary roof.

[0003] The main structure of the deformation joint corresponding to the existing temporary roof is cast in one piece with reinforced concrete and the beams or floor slabs. It is a permanent roof structure. If the deformation joint needs to be removed during the secondary development construction, the noise or vibration during the removal process will have a great impact on the lower space and the surrounding environment. In addition, this type of demolition requires more dehumidification operations, a long construction period, high costs, and the original structural slab is easily damaged due to improper operation during the removal process, which poses certain safety hazards.

[0029] This embodiment discloses a temporary roof deformation joint structure suitable for TOD development and simultaneous implementation of cover plates, which is used to solve the problems existing in the prior art.

[0031] Among them, the structural beam 1 is reserved with a deformation joint, and concrete counter-ridges 11 are fixedly cast on both sides of the deformation joint, and their height is similar to the height of the secondary development finished surface to reduce construction costs and construction time, and there is no need to remove them when the secondary development construction is carried out. The building surface layer 4 is provided with a gap corresponding to the deformation joint, which includes a horizontal surface layer portion 41 and a vertical surface layer portion 42. The horizontal surface layer portion 41 is arranged on the top side of the structural beam 1, and the vertical surface layer portion 42 is fixedly connected to the end of the horizontal surface layer portion 41 and is arranged close to the deformation joint. The block counter-ridge 2 is overlapped on the top of the concrete counter-ridge 11, and the block counter-ridges 2 on both sides of the deformation joint form a cavity 9 to increase the height of the deformation joint, and the deformation joint cover plate 3 is overlapped on the top of the two block counter-ridges 2 to protect the block counter-ridges 2. In order to improve the waterproof performance of the utility model, the bottom waterproof layer 5 is arranged between the concrete counter-ridge 11 and the building surface layer 4, and the bottom waterproof layer 5 covers the top gaps of the two block counter-ridges 2. On this basis, the waterproof additional layer 6 is arranged between the bottom waterproof layer 5 and the deformation joint cover plate 3, so that the top view projection of the waterproof additional layer 6 covers the top gaps of the two block counter-ridges 2.

[0032] Compared with the prior art, the temporary roof deformation joint structure can realize roof transformation by dismantling the block anti-step 2 during the secondary development construction. This method will not damage the structural beam slab 1 and has better safety performance and longer service life.

[0033] It should be noted that the bottom waterproof layer 5 and the additional waterproof layer 6 need to extend to both sides of the deformation joint until the top surface of the structural beam 1 is completely covered. The bottom waterproof layer 5 and the additional waterproof layer 6 can be waterproof rolls, which are light, highly integrated and easy to lay and disassemble.

An upper tongue 311 is provided at one end of each prefabricated module 31, and a lower tongue 312 is provided at the other end. The prefabricated module 31 is overlapped with the lower tongue 312 of the adjacent prefabricated module 31 through the upper tongue 311, thereby realizing the detachable connection of the deformation joint cover plate 3. Among them, a drainage slope 313 in the shape of an inverted "V" is provided on the top of each prefabricated module 31, and a guide groove 314 is provided at the end of the lower tongue 312.

[0039] Through the above technical scheme, a guide steel plate 7 and a water receiving trough 8 are arranged at the lower part of the deformation joint, which can prevent the seepage water in the deformation joint from invading the bottom of the structural beam 1 due to capillary suction, thereby reducing the possibility of affecting the indoor ceiling decoration and improving the service life of the deformation joint structure of the utility model.

[0040] It should be noted that the water receiving trough 8 can be connected to a preset rainwater collection device to discharge the accumulated water in time.

[0041] It should be noted that if the temporary roof deformation joint structure of the utility model is subjected to secondary development construction, the following can be obtained: Figure 3 Modified roof shown.

[0042] The specific construction method of the utility model embodiment is:

[0043] 1. Preset deformation joints for the structural beam slab 1, and simultaneously pour the concrete counter-slope 11 and the guide steel plate 7.

[0044] 2. Lay or overlap blocks on the concrete counter-ridge 11 (without pouring) to form a detachable block counter-ridge 2.

[0045] 3. Lay a bottom waterproof layer 5 on the structural beam 1 and the block counter-ridge 2. The bottom waterproof layer 5 covers the deformation joint and reserves a groove 10 in the deformation joint cavity 9.

[0046] 4. Place a water-swellable waterstop strip 101 in the groove 10, and lay a waterproof additional layer 6 on the water-swellable waterstop strip 101. The waterproof additional layer 6 and the bottom waterproof layer 5 should completely cover the deformation joint cavity 9 and the anti-ridge, and also extend to between the deformation joint structural beam 1 and the building surface layer 4.

[0047] 5. Lay the building surface layer 4 on the waterproof layer. Note that before laying the building surface layer 4, the integrity and firmness of the waterproof layer and the waterproof additional layer 6 should be checked.

[0048] 6. Install the deformation joint cover plate 3 on the installation area so that the deformation joint cover plate 3 covers the block anti-ridge 2. The anti-ridge and the cover plate are fixed with weather-resistant sealant 102.
