The steel column 1 has an I-shaped cross section, and the lower half portion of the steel column is embedded in a reinforced concrete wall 5, as shown in fig. 5. The cross beam 2 is a C-section with lips, welded to the steel column 1, and serves as a structural support and also as a sliding track for the pulleys 16 at the end of the translation truss 12, as shown in fig. 6. The longitudinal beam 3 is of a C-shaped section and is welded on the steel column 1 as shown in figure 7. The reinforced concrete slab 4 is integrally poured on the reinforced concrete wall 5 to play a role of bearing a test house, and a drainage port 17 is formed in the upper portion of the reinforced concrete slab 4, so that test water can flow back into the water tank 11 for recycling, as shown in fig. 1-2 and 8. Steel embedded parts 18 are embedded at four corners of the reinforced concrete slab 4 to play a role in corner reinforcement, as shown in figure 8. The water glass plate 6 is installed on the steel column 1, plays a role of preventing water from flowing into the water outlet 17 completely, and is transparent to observe the internal test state.
The water supply pump group 7 comprises a water pump 19, a water inlet pipe 20, an orifice 21, a water outlet pipe 22, a water feeding pipe 23, a water discharging pipe 24, a water feeding valve 25 and a water discharging valve 26, and is shown in fig. 1. During the test, the water feeding valve 25 is opened, the water discharging valve 26 is closed, the water pump 19 is opened, water flows into the water inlet pipe 20 from the water tank 11 through the hole 21, flows in and out the water pipe 22 through the water pump 19, and then is shunted into the water supply pipes 8 connected with the spray headers 9 through the water feeding pipe 23, so that the spray headers 9 spray, and the rainfall simulation is recorded and controlled by the flow meter 27 connected with the water feeding pipe 23.

The water supply pipes 8 and the shower heads 9 are fixedly mounted on a translation truss 12, as shown in fig. 6, and pulleys 16 at the end of the translation truss 12 realize the translation of the whole shower device on the cross beam 2. Folding and unfolding of sets of translation trusses 12 (A, B, C, D in fig. 3) is achieved by opening guys 13, closing slings 14 and winching device 15. As shown in fig. 4, two sets of opening and closing cables 13, 14 mounted at both ends of the translation truss 12 are driven and turned around the opening and closing cable hubs 37, 38 via first, second and third pulleys 29, 30 and 31, respectively. The winding-differential assembly 36 rotates the drive gear 32 via the drive shaft 35. When the driving gear 32 rotates clockwise, the opening gear 33 and the closing gear 34 rotate anticlockwise, so that the opening cable 13 is wound on the opening cable hub 37, the closing cable 14 is loosened from the closing cable hub 38, and the translation truss 12 moves to the right to realize folding opening. When the driving gear 32 rotates anticlockwise, the opening gear 33 and the closing gear 34 are driven to rotate clockwise, so that the opening cable 13 is loosened from the opening cable hub 37, the closing cable 14 is wound on the closing cable hub 38, and the translation truss 12 moves leftwards to realize unfolding and closing.
Wherein the opening cable 13 is wound around the first pulley 29 on the opening cable hub 37; the closing sling 14 is wound around the closing hub 38 after passing around the third pulley 31 and the second pulley 30 in this order. The opening cable 13 is wound in the opening cable hub 37 in the opposite direction to the closing cable 14 in the closing cable hub 38. As shown in fig. 9, the opening cable 13 is only fixedly connected to the leftmost one of the translatory girders 12(a) in the form of a pier anchor of a rigging, and passes through the pre-opened hole 39 in the other translatory girder 12(B, C, D). The closing slings 14 are fixedly attached to each of the translating trusses 12(A, B, C, D) with the two end trusses A, D attached to the closing slings 14 in the pier anchor form of the rigging and the middle truss B, C attached to the closing slings 14 in the anchor cone form of the rigging.
As shown in fig. 10, when opening cable 13 is tensioned, translating truss 12(a) is pulled to the right, in turn colliding with B, C, D, which pushes them to the right, effecting an opening fold of translating truss 12(A, B, C, D). As shown in fig. 11, when closing slings 14 are taut, translating truss 12(a) is drawn to the left, and when closing slings 14 are taut between a and B, translating truss 12(B) is also drawn to the left, and so on to effect closed deployment of translating truss 12(A, B, C, D).
The upper and lower floor seams of the test house are shown in figure 13. The structure of the device comprises an upper-layer bottom frame beam 40 (which is used for bearing an upper-layer box body wallboard 41), a lower-layer top frame beam 42 (which is used for bearing a lower-layer box body wallboard 43), a water-retaining flitch 44 (which is used for blocking wind and preventing water at the gap between the upper-layer box body and the lower-layer box body), a water-absorbing sponge 45 (which is used for assisting in measuring leakage) and a humidity sensor 46. If water seeps from the seams, water is absorbed by the absorbent sponge 45, and the water seepage can be measured through the reading of the humidity sensor 46. Humidity sensors 46 are also embedded in the upper and lower layers of wall bodies to measure the water seepage condition of the wall bodies.
The house joint internal test layout is shown in fig. 11, and acid-base indicator paper 51 is stuck to the joints of the roof/wall surface contact surface 47, the box beams 48, the box columns 49 and the box joints 50 by using neutral adhesive. When a leak occurs at the seam, the alkaline baking soda solution chemically reacts with the acid-base indicator, so that the acid-base indicator changes color, and the leak location 52 can be quickly found out through the color.

The winding-differential assembly 36 drives the driving gear 32 to rotate through the transmission shaft 35. When the driving gear 32 rotates clockwise, the opening gear 33 and the closing gear 34 rotate counterclockwise, so that the opening cable 13 is wound on the opening cable hub 37, the closing cable 14 is unwound from the closing cable hub 38, and the translation truss 12 moves to the right. As shown in fig. 10, when opening cable 13 is tensioned, translating truss 12(a) is pulled to the right, in turn colliding with B, C, D, which pushes them to the right, effecting an opening fold of translating truss 12(A, B, C, D).
