This setting combines together drainage and the water-blocking, and first sealing member 4 plays effective hydrophobic effect, and drainage space 31, the space 32 that blocks water carry out the drainage respectively and block water, reduce assembly type structure wall's ponding, infiltration phenomenon effectively, and water-proof effects is good. The sealing strip 6 and the first sealing element 4 are both made of elastic materials, and the specific materials are the prior art and are not described herein.

As an example of the present invention, the second wall 2 is provided with a first wall 21, a connecting plate 23, and a second wall 22, which are vertically connected, at one end close to the first wall 1, and the first wall 21 and the second wall 22 are respectively located in the water blocking space 32 and the drainage space 31. Preferably, the second wall 22 is provided with a water chute 24 and a water diversion structure 25, the water diversion structure 25 is positioned between the water chute 24 and the first sealing element 4, and the water diversion structure 25 is arranged at one end close to the water chute 24 and is inclined downwards. After the rainwater is drained to the drainage space 31, the rainwater flows downwards through the water chute 24, and is prevented from further flowing to the first sealing element 4; after a small amount of rainwater is close to the first sealing element 4, the rainwater can be quickly drained into the water guide groove 24 arranged close to the outer side of the wall body through the water diversion structure 25, the possibility of water drainage is smooth, the possibility of inward infiltration is low, and the waterproof effect is good. The assembly of the water diversion structure 25 and the second wall 22 is the prior art, such as clamping, inserting or screwing, and will not be described herein.

As an example of the present invention, the gutter 24 includes a first side wall 241, a second side wall 242, and a third side wall 243 which are connected, an included angle α 1 is formed between the first side wall 241 and the second side wall 242, and an included angle α 2 is formed between the third side wall 243 and the second side wall 242, wherein 90 ° < α 1 < 180 °, and 0 ° < α 2 < 90 °, the arrangement facilitates rainwater entering the drainage space 31 from the outside to flow into the gutter 24; the horizontal distance from the rainwater to the first sealing element 4 is changed from a straight line to a broken line shape, so that the contact between the rainwater and the first sealing element 4 is reduced; the arrangement of the water guide groove 24 formed by partially recessing the second wall 22 can increase the cross section of the water discharge space 31, facilitate the arrangement of the structure of the water discharge box 5 and the like, and ensure smooth water discharge.

As an example of the present invention, the water diversion structure 25 includes a first flow channel 251, a second flow channel 252, and a third flow channel 253 which are arranged in a hollow manner, wherein the first flow channel 251, the second flow channel 252, and the third flow channel 253 are inclined downwards at one end close to the water chute 24 and form included angles β 1, β 2, and β 3 with a horizontal plane, respectively, where 0 ° < β 1 < β 2 < β 3 < 90 °. The arrangement can further increase the difficulty of the contact between the rainwater and the first sealing element 4, and the waterproof effect is good; in addition, for the upper part position with more rainwater, adopt the little first runner 251 drainage of inclination, play the cushioning effect. The first flow channel 251, the second flow channel 252 and the third flow channel 253 may have the same or different structures. Preferably, the first flow channel 251 includes a capillary tube 26 having a cylindrical shape, and a central axis of the capillary tube 26 is disposed parallel to the second wall 22 and is located in the drain space 31. That is to say: the central axis of the capillary tube 26 is located on the side of the second wall 22 adjacent to the first wall 1. This arrangement utilizes the capillary action of the capillary tube 26 to make the rainwater close to the first sealing member 4 flow to the water guide groove 24 rapidly, and at the same time, the distance between the two sides of the first flow channel 251 and the second wall 22 is gradually increased, so as to play the same capillary action to make the capillary tube 26 play three roles, and the water guiding effect is good. Preferably, the arc by which the capillary tube 26 is embedded within the second wall 22 is θ, wherein 90 ° < θ < 180 °; preferably, the value of θ is 120-.

As shown in fig. 4 and 5, the first flow channel 251 further includes a flow aid 27 spaced apart from the capillary tube 26, the flow aid 27 is hollow inside and communicates with the capillary tube 26; the inner wall surface of the flow aiding part 27 is provided with a drainage rib 28, and the drainage rib 28 is spirally arranged along the central shaft direction of the flow aiding part 27. The rainwater entering the flow aiding piece 27 is guided by the drainage ribs 28 to form spiral water flow, so that a dragging effect is formed; cooperating with the capillary effect of the capillary tubes 26 further enhances the water diverting capability.

Preferably, the drainage ribs 28 are multiple and arranged along the peripheral side of the inner wall of the flow aid 27, and the drainage ribs 28 do not overlap each other in the projection direction. The arrangement is convenient for mold stripping and production and processing; the reduction of the flow speed caused by the mutual impact of the spiral water flows is prevented, and the clockwise or anticlockwise spiral water flows are formed conveniently. Preferably, 5 drainage ribs 28 are arranged at equal intervals along the circumferential side of the inner wall of the flow aid 27. This setting can compromise the drainage effect and the material cost of formation, simple structure and the production and processing of being convenient for. The lengths of the drainage ribs 28 and the flow aid 27 are H2 and H1 respectively, wherein the lengths of 1/2H 1 are not less than H2 and not more than 3/5H 1, so that rainwater in the capillary tube 26 can smoothly enter the flow aid 27. Preferably, the thickness of the drainage rib 28 is 0.1-0.15 mm; if the thickness is too thin, spiral water flow cannot be formed, and if the thickness is too thick, the water diversion speed is insufficient, even water blockage is caused.

As an example of the invention, the flow guiding rib 28 comprises a flow guiding part 281, a flow guiding part 282 and a siphon part 283 which are sequentially connected from top to bottom, the flow guiding part 281 comprises a first side part 2811 and a second side part 2812 which are connected, the first side part 2811 and the second side part 2812 are both in a rounded arrangement, and the radiuses of the rounded parts are R1 and R2 respectively, wherein R1 is less than R2. This setting can make drainage portion 281 become the fillet for no platform, and is little to the resistance that gets into the rainwater through capillary 26, and the drag effect is strong. As an example of the present invention, R2 ═ 0.2mm, R1 ═ 0.05 mm; the right side of the flow guiding part 282 protrudes outwards, and the formed working flow guiding line enables water flow to generate an adsorption effect. Horizontal gaps among the adjacent drainage portions 281, the adjacent flow guide portions 282 and the adjacent siphon portions 283 are respectively L1, L2 and L3, and L3 < L2 < L1. The arrangement can enable the flow velocity of the siphon part 283 to be larger than that of the drainage part 281, so as to form a dragging effect on the spiral water flow in the flow aid 27 and improve the water diversion strength. Preferably, the slope of the drainage rib 28 is 0.2-0.4mm, and the slope is a horizontal distance between a leftmost end of the second side portion 2812 arranged on the right side of the drainage rib 28 and a rightmost end of the drainage rib 28, that is to say: a horizontal distance between a junction of first side 2811 and second side 2812 and a rightmost end of siphon 283. If the gradient is too large, the blocking area of the drainage rib 28 is easily too large, so that the blocking effect on rainwater entering the flow assisting piece 27 is generated, and the drainage capability is weak; if the gradient is too small, the dragging effect is poor, so that the water diversion capability is limited.

As an example of the present invention, the first flow channel 251 further includes a plastic coating 29, the capillary tube 26 and the flow aid 27 are made of copper, and the plastic coating 29 is located on the outer wall surface of the capillary tube 26 and the flow aid 27. The arrangement can solve the problem that the plastic is easy to age, and has both mechanical strength and production cost; the first runner 251 is integrally formed, so that the demolding processing is facilitated, and the assembly is convenient; the first flow channel 251 can be prepared by the following method: mixing polyethylene, color master batch and ethylene-vinyl acetate polymer, wherein the weight percentages of the polyethylene, the color master batch and the ethylene-vinyl acetate polymer are respectively 79%, 13% and 8%; s2, melting the mixed material at 143 ℃; s3, heating to 168 ℃ at the speed of 0.5 ℃/min, and uniformly wrapping the capillary 26 and the outer wall of the flow aid 27; and S4, cooling with normal temperature water for 2.5min, and solidifying.

As shown in fig. 6, the first seal 4 includes a first rubber layer 41, a second rubber layer 43, and a metal layer 42 disposed in front of the first rubber layer 41 and the second rubber layer 43. The metal layer 42 is matched with the first rubber layer 41 and the second rubber layer 43, so that the structural stability of the first sealing element 4 can be enhanced, the assembly operation is simpler, and the efficiency is high. Preferably, a mounting groove 11 is formed in one side of the first wall 1, and the first sealing member 4 is interference-mounted in the mounting groove 11. The width of the first sealing element 4 in the free state is slightly greater than the width of the assembly groove 11, so that the effect of sufficiently fixing the first sealing element 4 in the preassembly phase is achieved. Preferably, the first rubber layer 41 and the second rubber layer 43 are integrally formed, and the metal layer 42 is assembled by elastic deformation of the first rubber layer 41 and the second rubber layer 43, so as to prevent water from leaking from the joint. Preferably, the first rubber layer 41 is provided with a water stop rib 411 extending along a first direction on a side away from the metal layer 42, and a groove for accommodating the water stop rib 411 is provided at a corresponding position of the assembly groove 11; the first rubber layer 41 is further provided with a positioning rib 412, and the positioning rib 412 is arranged adjacent to the water stop rib 411 and extends along a second direction; the corresponding position of the assembly groove 11 is provided with a positioning groove for accommodating the positioning rib 412. As an example of the present invention, the first direction and the second direction are horizontal and vertical directions, respectively. This setting is spacing from equidirectional to first sealing member 4, and the skew leads to leaking when avoiding the assembly, increases the distance that gets into the space 32 that blocks water, and waterproof performance is good. Preferably, the structure of the second rubber layer 43 is the same as that of the first rubber layer 41, and the first rubber layer 41 and the second rubber layer 43 are arranged in a central symmetry manner, so that the first sealing element 4 is not divided into two parts, and the assembly efficiency is high.

Part of the rainwater splashes to the first sealing element 4 after dropping down along the water diversion structure 25, increasing the risk of rainwater infiltrating into the water blocking space 32. For this reason, the applicant made the following improvements. As shown in fig. 2 and 7, the fabricated building wall further includes a drainage box 5, and the drainage box 5 is located at the lower part of the drainage space 31; at least one side of the drainage box 5 is provided with an abutting part 55 which is used for abutting and assembling with the first wall body 1 and/or the second wall body 2. The drainage box 5 comprises a box body 51 with a hollow interior, a water inlet 52 and a water outlet 54 are respectively arranged at the top and the lower part of the box body 51, a water retaining ring 53 is arranged at the water inlet 52, and the water retaining ring 53 extends into the box body 51. This setting makes the rainwater of drippage get into box body 51 through water inlet 52 in, utilizes manger plate circle 53 to form the buffering to the rainwater, reduces its and the collision strength of box body 51 bottom, increases the spill degree of difficulty.

As an example of the present invention, the water blocking ring 53 includes a connecting portion 531 and a water blocking portion 532, the connecting portion 531 is disposed in a ring shape, one side of the connecting portion 531 is connected to the water inlet 52, and the other side of the connecting portion 531 is connected to the water blocking portion 532. Preferably, the connection portion 531 is disposed lower than the top surface of the case 51 with a step structure formed therebetween. The water blocking portion 532 may be disposed in a column shape or a cone shape. Preferably, the water blocking portion 532 gradually shrinks from the upper end to the lower end toward the central axis of the water inlet 52, that is, the aperture of the circular hole at the lower end of the water blocking ring 53 is smaller than the aperture of the circular hole at the upper end. This arrangement makes the rainwater contact the water blocking portion 532 in a non-perpendicular manner to form a buffer, thereby alleviating the impact force between the rainwater and the bottom and increasing the difficulty of splashing the rainwater in the box body 51. Preferably, the water blocking portion 532 is provided with at least one notch 533, and the inside of the box body 51 is always communicated with the atmosphere due to the notch 533, so that water can smoothly enter the box body.

The first sealing member 4 is susceptible to aging cracking after long-term use, and the risk of water seepage is sharply increased. For this reason, the applicant has studied the filler of the water blocking space 32. The water-blocking space 32 is filled with a mixture of expanded microspheres and sealant, wherein the filling ratio of the expanded microspheres is 20% to 50%, and the filling ratio of the sealant is 50% to 80% (not shown in the figure); preferably, the expanded microspheres: the proportion of the sealant is 40: 60. The rainwater is absorbed by the expanded microspheres after entering the water blocking space 32, and the expanded microspheres are in a semi-flowing state after absorbing a small amount of water and are mutually extruded to fill the cracks of the first sealing element 4, so that the plugging effect is achieved. The sealant is made of the prior art and is not described herein in detail.

The expanded microspheres comprise 2-acryloyl ethane sulfonic acid, gelatin, polyethylene glycol and bis-succinimidyl glutarate in a ratio of 61: 7: 2:1, wherein the crosslinking density of the expanded microsphere is more than or equal to 0.27 and less than or equal to 0.38 of Cd. The arrangement can keep the fluidity of the expanded microspheres for a longer time; meanwhile, the phenomenon that the water absorption capacity is strong and the outer wall of the outer wall is expanded to influence the attractiveness is avoided. As an example of the present invention, the expanded microspheres are prepared by the following method: weighing 2-acryloyl ethane sulfonic acid and gelatin according to the weight, adding into hot water at 60 ℃, stirring and dissolving for 8 hours; s2, heating to 80 ℃, and then adding polyethylene glycol and bis-succinimide glutarate for polymerization; s3, filtering, drying with hot air at 150 deg.C for 16min, and pulverizing with needle mill to particle size D90 less than 150 μm.

An assembly type building comprises the assembly type building wall body. The fabricated building has the same beneficial effects as the fabricated building wall body, and the description is omitted here.

Example 2

The invention also provides an assembly process of the assembly type building, which comprises the following steps:

s1, pouring a ground beam on the ground, wherein the ground beam is provided with an embedded part, and two ends of the top of the ground beam are provided with tongues and grooves;

preferably, the embedded part is composed of a flat plate and reinforcing steel bars uniformly distributed at the bottom of the flat plate, the reinforcing steel bars are embedded in the ground beam, and the flat plate is exposed at the rabbet at the top of the ground beam. As an example of the invention, the steel bars on the embedded parts are hook-shaped steel bars with hook-shaped bottom ends.

S2, assembling the first sealing element 4 into the assembling groove 11, connecting and fixing the first wall 1 and the second wall 2 with the ground beam through fixing pieces, and forming a vertical seam 3 between the first wall 1 and the second wall 2; the width of the vertical joint is 10-15mm, the height of the groove and tongue is 50-80 mm, and the width of the groove and tongue is 30-50 mm.

S3, plugging a drainage box 5 into the bottom of the vertical joint 3, and collecting rainwater flowing down from the water guide groove 24 and the water guide structure 25 through the drainage box 5;

s4, cleaning burrs and concrete chips in the water blocking space 32 by using a steel wire brush, and filling a mixture of expanded microspheres and sealant;

s5, installing the sealing strips 6 on the inner side and the outer side of the vertical joint 3, and sequentially coating the sealing glue coating and the waterproof coating. Preferably, the installation environment is at a temperature of 19-25 ℃ and a relative humidity of 50-59%. If the environmental temperature is too low, the adhesive property of the sealant is poor; if the temperature is too high, the sag resistance of the sealant is deteriorated, the curing time is accelerated, and the use time and the finishing time are shortened; when the relative humidity is too high, it is obvious that the expanded microspheres are easy to expand to cause poor assembly, and when the relative humidity is too low, the curing speed is affected.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
