Further, the JS composite plate is adhered to the outer side of the waterproof layer through an adhesive. The JS composite board is firmly and compactly adhered to the outer side of the waterproof layer through the adhesive, the anti-impact performance of the waterproof layer (waterproof coiled material) is not reduced, and especially when backfill soil is backfilled along the outer wall surface, the effect of practicability is better, and the effect of construction quality of the JS composite board is equivalent to that of an original brick wall and a benzene board.
Still further, in order to make the JS composite plate have better pasting effect; accordingly, the adhesive comprises: and (5) adding mortar with glue. That is, the JS composite board is stuck on the outer side of the waterproof layer through the mortar added with glue. The adhesive is mixed and proportioned according to the proportion of polymer mortar to building 801 glue=10:1 (weight ratio).
The present solution is further described below in connection with specific embodiments:
the technology principle is as follows:
firstly performing large-surface waterproof construction on an outer wall, and then performing overhead construction on a JS composite board waterproof protection layer of the waterproof surface of the outer wall from a second preset position of the outer wall by a reverse construction method, so that the waterproof layer and the JS composite board waterproof protection layer can be constructed on the top of the outer wall of a basement at one time through an outer scaffold;
after the construction of the waterproof layer and the waterproof layer of the outer wall elevation is completed, the outer frame is removed, the exposed enlarged foundation top surface is cleaned, the waterproof layer is constructed, the foundation side surface is connected with the waterproof layer of the outer wall elevation, the waterproof layer of the JS composite board is constructed in a supplementing mode, and finally the concrete waterproof layer of the foundation top surface is poured.
When an outer wall is penetrated, the waterproof coiled material can be directly paved, then the whole JS composite plate is used for covering protection, and hole opening construction is carried out in the later period of re-excavation.
The construction process flow of the scheme comprises the following steps:
the construction method comprises the following specific construction process flows of outer wall elevation waterproof construction, outer wall elevation first JS composite board construction, outer wall elevation JS composite board large-area pasting, outer frame removal, outer wall elevation bottom waterproof construction, outer wall elevation bottom JS composite board and bottom plate fine stone concrete protection layer construction, layered backfilling and tamping:
(1) Waterproof construction of the vertical face of the outer wall;
manually cleaning a base layer, spraying isolation oil, pasting an additional layer, pasting a waterproof coiled material 50 downwards from the top of the basement outer wall by means of an outer frame until a first overhead position of the basement outer wall after acceptance, wherein the waterproof coiled material 50 is laid in the first overhead position, so that the waterproof coiled material on the top surface of a foundation can be conveniently stretched into the waterproof coiled material on the facade, and the left and right staggered joints are more than 0.5 m;
(2) Constructing a first JS composite board on the vertical face of the outer wall;
the JS composite board material generally adopts a size of 1.2 x 0.6m according to the field condition, so that a worker can conveniently adopt canvas slings to transport vertically, and the blocks are not too small, and the paving and pasting are labor-consuming;
the JS composite board is constructed and pasted from the height of 1.2m from the top surface of the foundation in an overhead mode according to the height of the virtual paving at the bottom of the elevation waterproof coiled material (the concrete height is mainly controlled by referring to the height 600mm of the JS composite board);
a row of small cross bars are erected at the height of 1.2m of the outer scaffold to extend to the outer wall surface by means of the outer scaffold system at the second overhead position, a gap of 1-2 cm is reserved between the small cross bars and the outer wall surface, the small cross bars are prevented from directly damaging waterproof coiled materials, and a layer of battens (namely flat supporting plates) are transversely arranged on the small cross bars and used for supporting the first JS composite plates;
the adhesive is stirred and mixed according to the proportion of polymer mortar to building 801 glue=10:1 (weight ratio), the adhesive is scraped on the JS composite board, the thickness is about 5mm, and the adhesive is paved on a wall elevation;
(3) The JS composite board of the outer wall elevation is stuck in a large area;
after the strength of the adhesive of the first JS composite plate meets the requirement, the next JS composite plate can be continuously adhered through drawing and impact checking. According to weather, air temperature and other conditions, the adhesive is generally adhered for no more than 2 times (1.2 m high), and after the strength is met, the adhesive of the next JS composite plate is carried out. When meeting a circle, a corner and the like, the JS composite board can be cut by adopting a handheld electric saw, the cutting is required to be directly and thoroughly cut, half of the cutting is not required to be cut, and the other half of the cutting is bent;
aiming at the situation that a reserved hole is arranged on the outer wall, arranging plates in advance to ensure that the hole is a complete JS composite plate; firstly, performing waterproof construction on a hole according to a normal waterproof process, then covering a layer of waterproof coiled material on the hole, directly sealing the hole by overlapping the waterproof coiled material with surrounding coiled materials by more than 25cm, and finally directly adhering and covering by adopting a whole JS composite board;
in the large-area construction process, if sudden rain appears in the temporary period, in order to avoid the impact and disturbance of the rain and sewage on the top plate on the JS composite plate, the slope can be found on the top surface of the JS composite plate by using mortar, so that the penetration and impact of the rain and sewage on the adhesive layer are reduced;
(4) The top of the JS composite board on the outer wall elevation is connected with the waterproof protection layer of the top plate;
if the elevation waterproof layer and the waterproof protective layer are preferentially constructed, the slope can be found from the mortar to the inner side edge on the top surface of the JS composite board, so that the infiltration and the impact of rain sewage to the adhesive layer are reduced; when the surface is paved and pasted on a large surface, the top surface of the JS plate can be made to be a reverse slope (the slope is towards the outer side) in the construction process temporarily in a rainy period, so that the infiltration and the scouring of rain and sewage are avoided;
if the waterproof layer and the waterproof layer of the roof surface are preferentially constructed, when the waterproof layer of the roof is constructed to the side of the outer wall, reserving a certain width (about 10 cm) without pouring concrete, after the JS composite board is adhered to the roof of the basement on a large surface, the elevation of the JS composite board is 2-3 cm lower than that of the roof structure, and finally, adopting fine stone concrete to repair the gap;
(5) Removing the outer frame;
after ensuring that the bonding strength of the JS composite plate meets the requirement, removing the outer frame, and removing the bracket under the first JS composite plate; during the dismantling process, the waterproof layer is not damaged, and the JS composite board is prevented from being scratched;
(6) Waterproof construction is performed on the bottom of the vertical face of the outer wall;
cleaning a base layer of an overhanging foundation top plate, everting waterproof coiled materials on the side surface of the foundation to the top surface of the foundation, sequentially overlapping the waterproof coiled materials, paving the waterproof layer upwards from the top surface of the foundation to an outer wall elevation, and then pasting the waterproof layer of the elevation on the upturned waterproof layer, so that the normal overlapping sequence of the waterproof coiled materials is ensured, and the overlapping of the waterproof coiled materials is ensured to meet the requirements;
(7) Constructing a JS composite board and a fine stone concrete protective layer of a bottom plate at the bottom of the outer wall elevation;
after the construction of the waterproof coiled material is completed, firstly pouring a plane fine stone concrete protective layer, and finding a certain small gradient from the wall edge to the foundation edge to ensure that no water is accumulated on the wall edge; after the concrete reaches the strength, the JS composite board at the bottom is patched in time;
(8) Backfilling soil;
and after the JS composite board reaches the strength requirement, tamping and backfilling according to the specification in layers.
The quality control measure of the process is as follows:
(1) in the construction process of the waterproof layer, constructors need to wear soft sole shoes, so that various sharp-pointed hard objects are prevented from damaging the waterproof layer;
(2) quality inspectors should perform quality inspection at any time and orderly in the construction process, if the places with damages and pricks are found, the operators need to be organized in time to repair correctly and reliably, so that hidden danger is avoided;
(3) under the condition that the bonding strength test is not carried out, the construction of the next JS composite plate is strictly forbidden, so that the potential safety hazards of large-area falling off, injury and the like caused by the falling off are avoided; the outer scaffold cannot be directly dismantled, so that the situation that the operation frame is required to be repaired after large-area falling is avoided, and time and labor are consumed is avoided;
(4) if the JS composite board is accepted, holes are directly drilled and the damage is removed, so that the damage to the flexibility and the water resistance of other boards is avoided;
(5) for places with more arc and corner changes, the JS composite plate is directly matched and cut in processing.
That is, the technology adopts an overhead construction JS composite board, directly uses the original outer frame system, under the condition that the top surface of an extended foundation is not constructed to be waterproof, directly constructs waterproof coiled materials vertically on an outer wall (which is paved from top to bottom) and the overhead construction JS composite board (which is paved from bottom to top), then removes the outer frame, cleans the extended foundation top surface, constructs the waterproof coiled materials at the position, and butts the waterproof coiled materials of the upper outer wall, then continues constructing the JS composite board downwards from the overhead position, ensures the construction integrity of the waterproof layer and the waterproof protection layer, and finally carries out the backfilling of the fertilizer groove. Therefore, the secondary erection of the operation frame can be avoided, the construction time of the waterproof protective layer is greatly reduced, and the potential safety hazard of building brick walls is eliminated.
The technology starts from the application of new waterproof protection layer materials and the construction convenience, adopts novel JS composite board materials for construction, can be constructed from the wall in the same way as the construction of the outer wall heat-insulation overhead method of a main building, directly and overhead pastes JS composite boards, and removes the waterproof protection layer at the bottom of an outer frame of the outer frame construction after the construction is completed.
