Description

Technical Field

[0001] The invention relates to the technical field of basement construction, and in particular to a construction process for an overhead basement outer wall waterproof protective layer. Background Art

[0002] At present, the exterior walls of basements generally use a combination of soft and hard methods such as polystyrene boards and brick walls as a waterproof protective layer to resist the impact of the backfill process on the waterproof material, so as to avoid damage to the waterproof material by the hard objects of the backfill material. Among them, during on-site construction, the waterproof layer and waterproof protective layer of the top surface of the foundation extending from the root of the exterior wall must be constructed first, and then the waterproof layer and waterproof protective layer of the exterior wall facade must be constructed. When constructing the waterproof layer and waterproof protective layer of the top surface of the foundation extending from the root of the exterior wall, it is necessary to first remove the exterior wall scaffolding located thereon. However, after the waterproof layer and waterproof protective layer here are constructed, it is necessary to re-erect the operating frame to construct the waterproof layer of the exterior wall facade, paste the waterproof protective polystyrene boards, and lay the brick wall, or to build the brick wall in the gaps between multiple backfills. This method greatly affects the construction period, is time-consuming and labor-intensive, and the brick wall is too high, posing a safety hazard of collapse during construction. Summary of the Invention

[0003] In view of this, the present invention provides a construction process for an overhead basement exterior wall waterproof protective layer, which can significantly reduce the construction period, ensure construction quality, and reduce the safety hazard of brick wall collapse.

[0012] Preferably, before the steps of sequentially pasting the multiple JS composite panels from bottom to top on the outer side of the waterproof layer with the help of an external frame, the method further comprises:

[0018] Preferably, each of the multiple JS composite panels consists of a plurality of JS composite panels arranged side by side in a horizontal direction.

[0019] Preferably, the JS composite panel is formed by sequentially pressing an external bonding reinforcement layer, a thermal insulation material layer, and a polymer mortar reinforcement layer.

DETAILED DESCRIPTION

[0031] This process, based on the application of new waterproof protective layer materials and construction convenience, uses a new JS composite board material as the waterproof protective layer for construction. The construction process can be similar to the main building's exterior wall insulation overhead construction method, starting from the wall, directly overhead and affixing the waterproof membrane and JS composite board upwards. After completion, the external frame is removed to construct the waterproof layer and waterproof protective layer at the bottom of the external frame. This process is suitable for the construction of waterproof protective layers on the exterior walls of various buildings, especially deep basements, especially those with projecting expansion foundations and limited space for basement fertilizer tanks. It significantly reduces construction time, ensures construction quality, and reduces safety hazards.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The embodiment of the present invention provides a construction process for the waterproof protective layer of the overhead basement exterior wall. Figure 1 Shown, including:

[0034] The waterproof layer is pasted between the first overhead portion and the top of the basement outer wall 10 by means of the external frame 20; wherein the waterproof layer is laid in the first overhead portion of the basement outer wall 10, and the first overhead portion of the basement outer wall 10 is 0.5m to 1m away from the bottom of the basement outer wall 10;

[0035] The JS composite board layer 30 is pasted on the outside of the waterproof layer by means of the external frame 20 to serve as a waterproof protective layer, and is distributed between the second overhead portion and the top of the basement outer wall 10; wherein the second overhead portion is higher than the first overhead portion;

[0036] Remove the outer frame 20, clean the bottom of the basement outer wall 10, extend the waterproof layer at the brick mold and stick it to the bottom of the basement outer wall 10, and extend it into the waterproof layer at the first overhead position and stick it;

[0037] The JS composite board layer 30 is additionally pasted between the second overhead portion and the bottom of the basement outer wall 10, and a concrete waterproof protective layer is poured in the foundation overhanging area.

[0038] It should be noted that the first overhead position of the basement outer wall 10 is the first preset position, and is 0.5m to 1m away from the bottom of the basement outer wall 10. The waterproof layer is laid in this empty space on the basement outer wall 10, so that the waterproof layer at the brick formwork is extended into the waterproof layer at this position to achieve overlap, and if Figure 3As shown, the waterproof layer is a waterproof membrane 50, and is laid from the top of the basement outer wall 10 downward to the first overhead position, that is, the waterproof membrane 50 is laid from the top of the basement outer wall 10 downward to the first overhead position with the help of the external frame 20; in addition, the second overhead position of the basement outer wall 10 is the second preset position, and is higher than the first preset position to avoid affecting the empty laying of the waterproof layer. The height of the second overhead position of the basement outer wall 10 (such as the second overhead position is 1.2m away from the bottom of the basement outer wall 10) is not higher than the height of the construction workers, which is convenient for the docking of the waterproof layer and the supplementary pasting of the waterproof protective layer; in addition, this solution uses JS composite board layer to replace the original brick wall + polystyrene board waterproof protective layer; of course, the waterproof layer and the waterproof protective layer need to cover the left and right sides of the basement outer wall 10.

[0039] In other words, this solution first uses an external frame to construct the waterproof layer and waterproof protective layer of the exterior wall facade in an overhead manner, then dismantles the external frame, and then constructs the waterproof layer and waterproof protective layer at the bottom of the exterior wall. This avoids the need to set up the operating frame twice, greatly reduces the construction time of the waterproof protective layer, and eliminates the safety hazards of brick wall construction. That is, after adopting the overhead basement exterior wall waterproof protective layer construction process provided by this solution, since brick wall construction is no longer considered, all the shortcomings of brick walls will be avoided, costs will be reduced, and construction period will be effectively shortened. In this way, this process is suitable for the construction of waterproof protective layers on the exterior walls of basements of all types of buildings, and is particularly suitable for deeper basements, especially those with projecting expansion foundations for basement foundations, and those with limited space for basement fertilizer troughs. The construction period is greatly reduced, and the construction quality is guaranteed, reducing safety hazards.

[0040] It can be seen from the above technical solutions that the construction process of the waterproof protective layer of the external wall of an overhead basement provided by the embodiment of the present invention has the following beneficial effects:

[0041] 3. From the perspective of construction period, the waterproof layer and the JS composite board layer can be constructed together with the help of external scaffolding, avoiding the need for secondary erection of operating frames, etc. In addition, for brick wall construction, the construction period is also longer, while the time for pasting the JS composite board layer is shortened by more than 60%; the construction period is shortened significantly. The deeper the basement, the shorter the construction period. The working surface of the basement outer wall fertilizer trough is handed over to the earthwork unit for backfilling in advance. Taking all factors into consideration, the basement backfilling period is shortened by more than 70% using this process.

[0042] 4. From the perspective of ensuring construction safety, during the brick wall construction process, due to the deep basement, the brick wall is not so stable and there is a great safety hazard. This solution uses the JS composite board layer 30 as a waterproof protective layer to eliminate the problems caused by the brick wall.

[0043] In this solution, the JS composite board layer 30 is pasted on the outside of the waterproof layer by means of the external frame 20 as a waterproof protective layer, and is distributed between the second overhead position and the top of the basement outer wall 10, including:

[0044] With the help of the external frame 20, multiple JS composite panels are sequentially pasted on the outside of the waterproof layer from bottom to top to serve as a waterproof protective layer, and are distributed between the second overhead part and the top of the basement outer wall 10.

[0045] It should be noted that if Figure 4 As shown, the JS composite board layer 30 is composed of multiple JS composite boards sequentially pasted on the outside of the waterproof layer from bottom to top, wherein, as shown in FIG. Figure 3 As shown, the first JS composite board 31 is attached to the outside of the waterproof layer at the second overhead portion of the basement exterior wall 10, and the remaining JS composite boards are sequentially laid above the first JS composite board 31. This design facilitates the layered (lane-by-lane) laying of the JS composite board layers 30.

[0046] Specifically, before the plurality of JS composite panels are sequentially pasted on the outer side of the waterproof layer from bottom to top by means of the external frame 20, the method further includes:

[0047] A bracket is set up on the external frame 20 and extends toward the second overhead portion of the basement outer wall 10 to support the first JS composite panel 31 of the multiple JS composite panels. This facilitates providing support for the laying of the first JS composite panel 31 and the entire JS composite panel layer 30, preventing the first JS composite panel 31 and the entire JS composite panel layer 30 from being laid out, thereby helping to ensure the stability of the laying of the JS composite panel layer 30.

[0048] Furthermore, the bracket includes: a crossbar assembly 21 and a support plate assembly;

[0049] The first end of the crossbar assembly 21 is mounted on the outer frame 20, and the second end faces the second overhead position of the basement outer wall 10; the support plate assembly is arranged at the second end of the crossbar assembly 21 and is used to support the first JS composite board 31 of the multiple JS composite boards. Figure 2 As shown, the crossbar assembly 21 is a small crossbar. Figure 3 As shown, the small crossbars are arranged in a row and spaced evenly along the length of the first JS composite panel 31. The support plate assembly is a flat support plate, with its bottom secured to the second end of the small crossbars and its top used to support the first JS composite panel 31. Of course, the number of flat support plates can be multiple, with multiple flat support plates distributed sequentially along the length of the first JS composite panel 31 and secured to the tops of the second ends of the small crossbars. This bracket design of this solution offers advantages such as simple structure and convenient support.

[0050] Furthermore, in order to prevent the JS composite board layer 30 from falling off in a large area, the step of sequentially pasting the multiple JS composite boards on the outer side of the waterproof layer from bottom to top includes:

[0051] Paste the first JS composite board 31 on the outside of the second overhead position of the waterproof layer on the basement outer wall 10. After testing that the bonding strength of the first JS composite board 31 meets the requirements, continue to paste the next JS composite board until the JS composite board is pasted to the outside of the waterproof layer on the top of the basement outer wall 10.

[0052] In this program, if Figure 3 As shown, each of the multiple JS composite panels is composed of multiple JS composite panels arranged horizontally side by side. In other words, the multiple JS composite panels are affixed horizontally side by side to the outside of the waterproof layer using an external frame 20 to form a single JS composite panel. This design facilitates the construction of each JS composite panel. Naturally, the gap between two adjacent JS composite panels in the first row 31 is offset from the gap between two adjacent JS composite panels in the second row 32. The same design is applied to the other adjacent JS composite panels.

[0053] Specifically, the JS composite board is a factory-prefabricated composite fireproof insulation formwork. The JS composite board is composed of an external bonding reinforcement layer, an insulation material layer, and a polymer mortar reinforcement layer, which are sequentially pressed together. Furthermore, the JS composite board has the following properties: extruded polystyrene density: 30-35kg / m³, compressive strength ≥0.15Mpa, thermal conductivity ≤0.030w / (m‧K). The composite insulation board has a surface density ≤35kg / m³, a flexural load ≥2000N, impact strength ≥10.0J, and tensile bond strength: original strength ≥0.10Mpa, water resistance ≥0.10Mpa, and freeze-thaw resistance ≥0.10Mpa. The JS composite board can withstand the impact of exterior wall backfill on the wall surface during backfilling, and also meet the insulation and energy-saving requirements during subsequent use.

[0054] Furthermore, the JS composite board is adhered to the outside of the waterproof layer with an adhesive. The JS composite board is firmly and densely adhered to the outside of the waterproof layer with the adhesive, without reducing the impact resistance of the waterproof layer (waterproof membrane). This provides better practicality, especially when backfill soil is backfilled along the exterior wall surface, and is comparable to the construction quality of the original brick wall + polystyrene board.

[0055] Furthermore, to ensure better adhesion of the JS composite board, the adhesive comprises a mortar with adhesive. In other words, the JS composite board is adhered to the outer side of the waterproof layer using the mortar with adhesive. The adhesive is mixed in a ratio of 10:1 (by weight) of polymer mortar to 801 architectural glue.

[0056] The present invention will be further described below with reference to specific embodiments:

[0057] Principle of this process:

[0058] First, carry out waterproofing construction on the large surface of the exterior wall, and then use the reverse method to construct the JS composite board waterproof protective layer on the exterior wall waterproof surface from the second preset position of the exterior wall. In this way, the waterproof layer and the JS composite board waterproof protective layer can be constructed to the top of the basement exterior wall at one time through the external scaffolding;

[0059] When the construction of the waterproof layer and waterproof protective layer of the exterior wall facade is completed, the external frame is removed, the top surface of the expanded foundation that is protruding outward is cleaned, and waterproofing is constructed here. The waterproofing of the foundation side is connected with the waterproofing of the exterior wall facade, and the JS composite board waterproof protective layer is supplemented. Finally, the concrete waterproof protective layer of the foundation top surface is poured.

[0060] When there is an opening through the exterior wall, waterproof membrane can be directly laid, and then covered and protected with a whole piece of JS composite board, and the opening construction can be carried out during the subsequent excavation.

[0061] The construction process of this scheme:

[0062] Waterproofing of exterior wall facade → Construction of the first layer of JS composite board on exterior wall facade → Large-area pasting of JS composite board on exterior wall facade → Removal of external frame → Waterproofing of exterior wall facade bottom → Construction of JS composite board + base plate fine stone concrete protective layer on exterior wall facade bottom → Layered backfilling and compaction. The specific construction process is as follows:

[0063] (1) Waterproof construction of exterior wall facades;

[0064] First, manually clean the base layer, spray isolation oil, and apply the additional layer. After acceptance, use the external frame to paste the waterproof membrane 50 from the top of the basement exterior wall downwards to the first overhead position of the basement exterior wall. The waterproof membrane 50 is laid in the first overhead position to facilitate the extension of the foundation top waterproof membrane into the interior of the facade waterproof membrane. The left and right sides are staggered by more than 0.5m.

[0065] (2) Construction of the first JS composite panel on the exterior wall;

[0066] JS composite board materials are generally in the size of 1.2*0.6m according to the site conditions. This is convenient for workers to transport vertically with canvas slings, and the size is not too small and labor-intensive to lay.

[0067] JS composite board is installed and pasted in an overhead manner starting from a height of 1.2m from the top surface of the foundation according to the height of the bottom of the facade waterproof membrane (the specific height is mainly controlled by referring to the height of JS composite board 600mm);

[0068] At the second overhead position, with the help of the external scaffolding system, a row of small horizontal bars are set up at a height of 1.2m on the external scaffolding, extending to the outer wall, leaving a gap of 1 to 2cm from the wall to prevent the small horizontal bars from directly damaging the waterproof membrane. Then, a layer of wooden squares (i.e., flat support plates) is placed horizontally on the small horizontal bars to support the first JS composite board.

[0069] Mix the adhesive in the ratio of polymer mortar: building 801 glue = 10:1 (weight ratio), scrape the adhesive slurry onto the JS composite board with a thickness of about 5mm, and then spread it on the wall facade;

[0070] (3) Large-area pasting of JS composite panels on the exterior wall;

[0071] After passing the pull-out and impact tests to ensure that the adhesive strength of the first layer of JS composite board meets the requirements, the next layer of JS composite board can be applied. Depending on weather conditions, temperature, and other conditions, generally no more than two layers (1.2m high) should be applied at a time. Once the strength meets the requirements, the next layer of JS composite board can be applied. When encountering rounded or cornered areas, the JS composite board can be cut with a handheld electric saw. The cut must be made directly through, and it cannot be cut in half and then bent in the other half.

[0072] For the case where there is a reserved opening for installation on the exterior wall, the panel should be arranged in advance to ensure that there is a complete JS composite board at the opening; first waterproof the opening according to the normal waterproofing process, and then cover the opening with a layer of waterproof membrane, overlapping it with the surrounding membrane by more than 25cm to directly seal the opening, and finally use a whole piece of JS composite board to directly stick and cover it;

[0073] During large-scale construction, if sudden rain occurs, in order to avoid the impact and disturbance of rainwater and sewage on the top plate on the JS composite board, mortar can be used on the top surface of the JS composite board to reduce the penetration and impact of rainwater and sewage on the adhesive layer;

[0074] (4) The junction between the top of the JS composite panel on the exterior wall and the waterproof protective layer of the roof;

[0075] If the facade waterproof layer and waterproof protective layer are constructed first, the top surface of the JS composite board can be sloped inward with mortar to reduce the penetration and impact of rainwater and sewage on the adhesive layer; including when paving large surfaces, the top surface of the JS board can also be temporarily sloped (sloped toward the outside) during the construction process during rainy seasons to avoid the penetration and scouring of rainwater and sewage;

[0076] If the roof waterproof layer and waterproof protective layer are constructed first, when the roof waterproof protective layer is constructed to the edge of the exterior wall, a certain width (about 10 cm) should be reserved without pouring concrete. After the large surface of the JS composite board is pasted to the basement roof, the elevation of the JS composite board is 2 to 3 cm lower than the elevation of the roof structure. Finally, fine stone concrete should be used to fill the gap here.

[0077] (5) Dismantle the external frame;

[0078] After ensuring that the bonding strength of the JS composite board meets the requirements, remove the external frame and the bracket under the first JS composite board; during the removal process, be careful not to damage the waterproof layer and avoid distorting the JS composite board;

[0079] (6) Waterproof construction at the bottom of the exterior wall;

[0080] Clean the base of the overhanging foundation top plate, turn the waterproof membrane on the side of the foundation outward to the top of the foundation, overlap the waterproof membrane in sequence, and lay the waterproof from the top of the foundation upward to the exterior wall facade. Then, stick the waterproof on the facade to the turned-up waterproof, ensuring that the waterproof overlap sequence is normal and that the waterproof membrane overlap meets the requirements;

[0081] (7) Construction of JS composite board + bottom plate fine stone concrete protective layer at the bottom of the exterior wall;

[0082] After the waterproof membrane construction is completed, first pour the flat fine stone concrete protective layer, and find a certain small slope from the wall to the foundation to ensure that there is no water accumulation on the wall; after the concrete reaches the required strength, timely fill the bottom JS composite board;

[0083] (8) Backfill soil;

[0084] After the JS composite board reaches the strength requirement, it should be compacted and backfilled in layers in a timely manner according to the specifications.

[0085] Quality control measures for this process:

[0086] ① During the construction of the waterproof layer, construction workers must wear soft-soled shoes to avoid damage to the waterproof layer by various sharp and hard objects;

[0087] ② During the construction process, quality inspectors should conduct quality inspections at any time and in an orderly manner. If any damaged or punctured areas are found, personnel should be organized to carry out correct and reliable repairs in a timely manner to avoid hidden dangers;

[0088] ③ It is strictly forbidden to carry out the construction of the next JS composite board without conducting a bonding strength test to avoid large-scale shedding and potential safety hazards such as injuries caused by it; it is also forbidden to directly dismantle the external scaffolding to avoid the time-consuming and labor-intensive re-erecting of the operating frame after large-scale shedding;

[0089] ④ It is not allowed to directly open holes or chisel away damage on the JS composite board that has been accepted, so as to avoid deflection of other panels and damage to waterproofing;

[0090] ⑤ For areas with many changes in arcs and corners, the JS composite board should be cut directly during processing.

[0091] In other words, this process uses an "overhead" construction method for JS composite panels. Using the existing external scaffolding system, without extending the foundation's top surface for waterproofing, waterproof membranes are vertically installed directly on the exterior wall (paved from top to bottom) and JS composite panels are installed overhead (multiple layers of JS composite panels are laid from bottom to top). The external scaffolding is then removed, the top surface of the expanded foundation is cleaned, and the waterproof membrane is installed there, docked with the waterproof membrane on the exterior wall. JS composite panels are then installed downward from the overhead area, ensuring the integrity of the waterproof and protective layers. Finally, the fertilizer trough is backfilled. This avoids the need for a secondary erection of the operating scaffolding, significantly reducing the construction time for the waterproof protective layer and eliminating safety hazards associated with brick wall construction.

[0092] This process, based on the application of new waterproof protective materials and construction convenience, utilizes new JS composite panels. Construction can be carried out using the same method as the main building's exterior wall insulation overhead construction, starting from the wall itself and directly attaching the JS composite panels overhead. After completion, the external scaffolding is removed to reconstruct the waterproof and waterproof protective layer at the bottom. This process is particularly suitable for deep basements, especially those with projecting foundations or limited space for basement fertilizer tanks. It significantly reduces construction time, ensures construction quality, and reduces safety hazards.

[0093] This technology can significantly shorten the construction period of the exterior wall waterproof protective layer, reduce potential safety hazards during the construction process, and ensure that the impact resistance of new materials meets the requirements, thereby meeting the needs of protecting the basement exterior wall waterproof layer. It is simple to construct, has good results, and has high promotion value.

[0094] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
