Description

Water-retaining house expansion joint structure

technical field

The utility model belongs to the technical field of rain-proof structures in substations, in particular to a water-retaining type house expansion joint structure.

Background technique

In the substation, some housing buildings are relatively long, which will be composed of multiple continuously arranged housing units, and there will be expansion joints between the housing units (adapting to thermal expansion and contraction), and because there are electrical equipment inside the housing unit, Rainwater must not enter during operation, so there must be a water-retaining structure inside and outside the expansion joints of the house to prevent rainwater from flowing into the house from the expansion joints and affecting the operation of electrical equipment. The current water-retaining structure is mainly water-retaining strips. The traditional water-retaining strip manufacturing process is to first install wooden boards for fixing on both sides of the expansion joint, and then cover them with water-retaining strips to play a waterproof role. In actual use, due to long-term rain erosion, the internal fixing boards rot, causing the water retaining strips to fall off, easily leading to failure of the water retaining structure, and even damage to the electrical equipment in the house.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

In the embodiment shown in Figures 1 to 4, a water-retaining house expansion joint structure includes two roofs 1 respectively arranged on two adjacent building monomers 7, and also includes

Top cover 2, the roof is provided with an accommodating groove 1a opening on the upper surface of the roof. The top cover includes an upper lobe plate 21 and two flat pressing plates 22 on opposite sides of the upper lobe plate. Corresponding to the roof one by one, the flat plate is attached to the corresponding roof;

Expansion joints 3 are formed between two adjacent housing units, the upper convex panel is above the expansion joint, and the vertical projection of the expansion joint falls within the vertical projection range of the upper convex panel;

The top cover also includes two vertical limiting plates 23, the vertical limiting plates correspond to the flat pressing plates one by one, in the corresponding vertical limiting plates and flat pressing plates: the flat pressing plate is located between the vertical limiting plate and the upper convex angle Between, the vertical limiting plate is connected with the flat pressing plate;

There is a one-to-one correspondence between the vertical limiting plate and the accommodating groove. In the corresponding vertical limiting plate and accommodating groove: the lower end of the vertical limiting plate is in the accommodating groove, and the inner side of any groove between the vertical limiting plate and the accommodating groove Horizontal telescopic gaps 23a are formed between the walls.

The expansion joint is provided with a support frame 41 and an elastic sealing plate 42 arranged on the support frame, and the elastic sealing plate is arranged horizontally. The support frame includes a support bar 411 arranged on the side wall of one of the single houses and a support bar 412 arranged on the side wall of one of the single house. The support bars are arranged in parallel, and the top surface of the support bar contacts the elastic sealing plate. The support bar is directly fixed on the side wall of the single building, and an elastic sealing plate is arranged on it. When the top cover is damaged (such as impact damage, rust damage, etc.), the elastic sealing plate can also play a temporary protective effect, buying time for maintenance or replacement of the top cover.

The accommodating groove is a through groove, and the length direction of the expansion joint is parallel to the length direction of the roof. In one roof: the accommodating groove runs through the length direction of the roof. Water is not easy to accumulate in the channel, which can prevent the vertical limit plate from being in water for a long time. In the corresponding vertical limiting plate and accommodating groove: an elastic limiting plate 5 is arranged in the accommodating groove, the elastic limiting plate is arranged vertically, and the elastic limiting plate is located between the vertical limiting plate and the expansion joint. The elastic limit plate can elastically limit the vertical limit plate, which not only avoids unnecessary movement of the entire top cover, but also leaves room for adjustment to adapt to deformation during thermal expansion and contraction. It also includes a downpipe 6 corresponding to the roof one-to-one. The roof includes a pedestal on the top of the building and eaves 11 arranged around the pedestal. In the corresponding roof and downpipe: the downpipe is arranged under the eaves, and The water pipe communicates with the holding tank. The downpipe can assist drainage, so that the accumulated water in the holding tank can be drained away quickly. In the corresponding vertical limiting plate and the accommodating tank: a vertical telescopic gap 23b is formed between the vertical limiting plate and the bottom of the accommodating tank; in the corresponding roof and the downpipe: the downpipe communicates with the bottom of the accommodating tank. The vertical expansion gap also leaves room for structural deformation during thermal expansion and contraction. The upper convex angle plate, each flat pressure plate and each vertical limit plate are integrally formed.

In the utility model, the flat pressing plate is attached to the corresponding roof to form a support, and the upper convex angle plate cooperates with the flat pressing plate to directly protect the expansion joints from rain and waterproof, so as to prevent rainwater from entering the house. The vertical limit plate cooperates with the accommodating groove and the elastic limit plate, and can play the effect of positioning the entire top cover. Normally, the elastic sealing plate does not work. When the top cover is damaged (such as impact damage, rust damage, etc.), the elastic sealing plate can also play a temporary protective effect, gaining time for maintenance or replacement of the top cover. And after rainwater enters in the holding tank, it can be discharged from the through end of the downpipe or the holding tank to avoid water accumulation.
