Description

Technical Field

[0001] The invention relates to a prefabricated hollow wall body free of mold removal, in particular to a prefabricated hollow wall body free of mold removal with integrated decorative structure, belonging to the technical field of external wall thermal insulation processing and production. Background Art

[0002] The traditional exterior wall insulation is the "post-anchoring and pasting method", that is: first make the exterior wall structure, then fix the insulation layer with rivets, and then cover the insulation layer with plaster, commonly known as the "thin plastering and pasting method". This method not only has poor insulation and energy-saving effects, but also has difficult quality control and is very likely to cause engineering accidents such as falling off.

[0003] Concept of decoration structure integration: The building exterior wall is divided into layers from outside to inside: external decoration layer, fireproof and thermal insulation layer, structural layer, and internal decoration layer. The external decoration layer and the fireproof and thermal insulation layer are combined with anchors and poured together with the structural layer, which is the decoration structure integration. Its advantage is that it prevents the thermal insulation layer from falling off and does not require multiple processes for decorating the exterior wall. The exterior wall panels that have decoration, fireproof and thermal insulation functions formed by pre-anchoring the external decoration layer, fireproof and thermal insulation layer are usually called integrated exterior wall panels.

[0004] Concept of non-removal formwork: Non-removal formwork is a formwork that is permanently integrated with the concrete structure.

[0005] Concept of prefabricated hollow wall: It is a form of prefabricated building wall, also called composite wall, which is divided into double-sided composite wall and single-sided composite wall. That is, the wall panels are prefabricated in the factory, and the cast-in-place cavity is reserved. The secondary pouring is completed at the construction site to form a structural force-bearing wall. Due to the cast-in-place cavity, it is convenient to connect the wall reinforcement up and down and left and right, which is more advantageous than the traditional prefabricated solid wall.

[0006] Existing structural forms and construction techniques of "decorative structure integrated prefabricated hollow wall without formwork removal" at home and abroad:

[0007] 1. Prefabricated sandwich facade:

[0008] (1) Structural form: It is a fully prefabricated wall, and the molding is completed in the factory, which meets the evaluation standards of prefabricated buildings. The wall is divided from the inside to the outside:

[0009] a) Inner leaf wall: a reinforced load-bearing structure, which is a structural load-bearing member, that is, the structural load of the prefabricated sandwich exterior wall is borne by the inner leaf wall. Due to factory prefabrication, the steel bars of the entire exterior wall must be cut off before completion, and the upper and lower floors of the house are connected to the wall load-bearing steel bars through the "sleeve grouting technology".

[0010] b) Fireproof and thermal insulation layer: laid between the inner and outer leaf walls.

[0011] c) Outer leaf wall: prefabricated concrete thin plate structure, connected to the inner leaf wall through special components, sandwiching the fireproof insulation layer in the middle.

[0012] d) Finishing layer: It is laid on the surface of the outer leaf wall panel to serve as a decorative effect.

[0013] (2) Construction technology:

[0014] a) Factory production: traditional craftsmanship.

[0015] b) On-site lifting and installation: The built-in sleeve of the upper wall needs to be accurately aligned with the reserved steel bars at the top of the lower wall.

[0016] c) Secondary grouting: After the wall is in place and calibrated, a key process must be completed: secondary grouting. Grout is a special and expensive material, and special equipment is required to fill the gaps between the sleeve and the wall with grout. That is, the connection of steel bars and the connection of wall gaps are completed by the secondary grouting process.

[0017] d) Curing and molding: traditional technology.

[0018] e)Completion.

[0019] 2. Integrated exterior wall with heat preservation structure without formwork removal:

[0020] (1) Structural form: Fully cast-in-place concrete walls, not a prefabricated building system. The outer wall formwork is replaced by an integrated insulation board, which is permanently combined with the concrete wall. The walls from the inside to the outside are:

[0021] a) Shear wall: reinforced load-bearing structure, traditional cast-in-place technology.

[0022] b) Formwork-free integrated panels: manufactured in the factory, that is, the thermal insulation and fireproof panels are combined together, and the anchors connected to the concrete structure are pre-set.

[0023] c) Outer surface: generally plastered and sprayed.

[0024] (2) Construction technology:

[0025] a) Shear wall reinforcement binding: traditional technology.

[0026] b) Internal formwork: usually steel formwork, aluminum alloy formwork or wooden formwork.

[0027] c) Installation of inner formwork back ribs: Back ribs are load-bearing members that enhance the overall rigidity of the formwork. They are generally perforated channel steels or parallel circular tubes, set horizontally, and the spacing between back ribs is determined by calculation.

[0028] d) Install integrated panels: The mold-free insulation panels are generally integrated panels, i.e. insulation layer + inner and outer lining panels, which increase the overall rigidity and strength so that they can be used as templates. Before installation, pre-drilling is required and insulation nails must be installed according to specifications.

[0029] e) Install the outer back ribs: At this time, the inner and outer back ribs are clamped with tension bolts to tighten the inner and outer molds.

[0030] f) Insert the tension bolts: The tension bolts connect the inner and outer back ribs to clamp the inner and outer formwork to ensure the stability of the wall when pouring concrete.

[0031] g) Casting concrete walls: traditional technology.

[0032] h) Curing and molding: traditional technology.

[0033] i) Pull out the tension screws and remove the inner and outer back ribs:

[0034] j) Removal of inner formwork: traditional process.

[0035] k) Hole sealing: Carry out in accordance with the requirements of specifications.

[0036] l) Insulation layer finishing: implemented in accordance with specification requirements.

[0037] m)Completion.

[0038] ii. Technical defects of existing structures and processes:

[0039] 1. Prefabricated sandwich facade:

[0040] 1) The factory production process is complicated, with low efficiency and high cost.

[0041] 2) Heavy components: difficult to transport and hoist.

[0042] 3) On-site alignment operations are difficult: the overall accuracy of the house is poor.

[0043] 4) Secondary grouting poses great safety risks, is often not fully filled, and lacks detection methods.

[0044] 5) There are horizontal seams all around each wall, which makes it very easy to leak.

[0045] 6) The outer wall panels are heavy, and they are connected to the inner wall panels that bear the load only through an insulation layer, so there is a huge risk of them falling off.

[0046] 2. Integrated exterior wall with heat preservation structure without formwork removal:

[0047] 1) Internal formwork problem: using traditional wooden formwork, steel formwork or aluminum alloy formwork, the wall reinforcement is tied on site, which fails to meet the basic requirements of prefabricated buildings.

[0048] 2) Difficult alignment operation: There are many holes for tension bolts on the inner mold, which makes it difficult to align with the outer insulation board. Because the template has low rigidity and large hole spacing, the template will deform and expand during concrete pouring, resulting in many holes.

[0049] 3) The insulation layer is easily damaged and difficult to detect: The insulation layer is directly opened without protective devices. When aligning, the screws are poked randomly, which can easily damage the soft insulation board. Because it is a "blind hole alignment", damage is not easy to detect.

[0050] 4) Wall precision control problem: The insulation layer is a soft body without infinite position device. It is easy to be compressed and deformed when the bolts are pulled together, especially from the appearance, the surface is uneven.

[0051] 5) Construction operation issues: In national standards and actual operations, the inner lining back rib method is used. That is, the weak points that are prone to mold expansion must first be placed with inner lining back ribs or pallets, and then clamped by the main back ribs. This will cause serious waste of materials. As long as the inner lining back rib is needed at one point, the whole piece must be set, otherwise the main back rib will be suspended in the air, and no mistakes are allowed.

[0052] 6) Cold bridge problem: It is mainly caused by the fact that when pouring concrete, the inner openings of the insulation layer are not protected by any measures. Especially during vibration, cement slurry will flow back to form a cold bridge, which seriously affects the insulation effect and is difficult to detect from the outside. Summary of the invention

[0053] The technical problem to be solved by the present invention is to provide a prefabricated hollow wall body with a simple structure, convenient and flexible decorative structure and integrated formwork-free design.

[0054] To solve the above problems, the specific technical solutions of the present invention are as follows: a prefabricated hollow wall with integrated decorative structure and free of mold removal, comprising a prefabricated composite wall panel and an integrated decorative panel, a cast-in-place cavity is arranged between the two, the other side of the integrated decorative panel is connected with an integrated panel back rib structure, a temporary support rod is arranged in the cast-in-place cavity, the integrated decorative panel is embedded in the bracket, the bracket is a frame structure, comprising a bracket bottom net, the bottom surface of the integrated decorative panel is in contact with the bracket bottom net, there are two bracket side frames, which are respectively connected integrally at the two ends of the bracket bottom net in the length direction, and a fixing ring is arranged at the bottom of the bracket side frame in the length direction.

[0055] A pull-tab sheath is vertically connected and penetrated along the length or width direction of the prefabricated composite wall panel. There are several pull-tab sheaths, which are arranged in parallel along the length direction of the prefabricated composite wall panel. The pull-tab sheath is in contact with the bottom net of the bracket. A template pull-tab is inserted into the pull-tab sheath, including a pull-tab. The pull-tab passes through the seam between the pull-tab sheath and two adjacent integrated decorative panels. A pull hole is arranged at one end of the pull-tab, and a handle is arranged at the other end of the pull-tab. A baffle is arranged on the side of the handle close to the pull-tab, and the handle and the baffle are located on the relatively outer sides of the prefabricated composite wall panel.

[0056] The described integrated board back rib structure includes a back rib main body. On both sides of the back rib main body in the length direction, end plates are integrally connected. Connection holes are provided on the end plates. The back rib main body and the end plates form a "U" - shaped structure, and the opening faces the opposite side of the integrated decorative board.

[0057] A back rib bottom plate envelope is sleeved on the bottom of the described back rib main body.

[0058] The described back rib bottom plate envelope is made of rubber and PVC flexible materials.

[0059] The height H of the bottom net of the described bracket includes the thickness of the concrete wall steel bar protection layer.

[0060] The inner spacing L between the two relatively arranged bracket side frames is the width of the integrated board, and its inner height H is not greater than the designed thickness of the integrated board.

[0061] The connection hole and the tension hole are coaxial and locked by a pin.

[0062] A T - shaped joint sealing strip is inserted into the gap between the bracket side frames of two adjacent brackets, and the vertical part of the T - shaped joint sealing strip is stuffed into the gap.

[0063] Compared with the existing technical processes, the beneficial effects of the present invention are as follows:

[0064] The present invention changes the "post - anchoring" of the building exterior wall insulation layer to "pre - anchoring", that is, the insulation layer anchor nails are cast together with the wall concrete, solving the potential safety hazard problem of the easy detachment of the insulation layer.

[0065] By adopting the pull - piece structure and the flexible back rib system, the problem of repeated processes of the decorative layer is solved.

[0066] It meets the current national evaluation standards for prefabricated buildings, that is, the semi - prefabricated process of the wall fully meets the various requirement indicators of the prefabricated buildings that the country is vigorously promoting.

[0067] At the present stage, the "grouting sleeve connection" process is adopted for precast solid shear walls, which has great potential safety hazards. The semi - precast composite wall solves the problem of the up - and - down through - connection of steel bars, making the building safer and more reliable.

[0068] Formwork is not required both internally and externally, greatly reducing the project cost, and at the same time realizing simple and fast construction.

[0069] Less equipment investment and quick results.

[0070] The on - site installation of the insulation board has no dead corners throughout the process, and the insulation effect is fully guaranteed.

[0071] The process is simple and the work efficiency is greatly improved.

[0072] The problem of the overall accuracy of the wall is solved, making the overall building more able to meet the aesthetic requirements.

[0073] Solved the problems of easy cracking and mold expansion during wall pouring;

[0074] Integrate insulation and structure, save energy and protect the environment, and do not fall off;

[0075] The overall project cost is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0086] like Figures 1 to 10 As shown, a prefabricated hollow wall with integrated decorative structure and no need to remove the formwork comprises a prefabricated composite wall panel 1 and an integrated decorative panel 4, a cast-in-place cavity 2 is arranged between the two, the other side of the integrated decorative panel 4 is connected to an integrated board back rib structure, temporary support rods 1-2 are arranged in the cast-in-place cavity 2, and concrete is poured into the cast-in-place cavity 2 at the construction site.

[0087] The integrated decorative board 4 is embedded in the bracket 3. The bracket 3 is a frame structure, including a bracket bottom net 3-1, which is a continuous, hollowed-out, ribbed grid board. Its height H2 is the thickness of the concrete wall steel bar protection layer, generally 15 mm. During use, the bottom surface of the integrated decorative board 4 contacts the bracket bottom net 3-1. There are two bracket side frames 3-2, which are continuous hollowed-out grid boards, and are respectively integrally connected to both ends of the bracket bottom net 3-1 in the length direction to restrict the horizontal position. The inner spacing L1 between the two relatively arranged bracket side frames 3-2 is the width of the integrated board, and its inner height H1 is not greater than the designed thickness of the integrated board. At the bottom of the bracket side frame 3-2 in the length direction, there is a fixing ring 3-3, which is convenient for inserting the pin 9.

[0088] Along the length or width direction of the precast composite wall panel 1, there are several pull-tab sheaths 7 vertically penetrating and connecting. The pull-tab sheaths 7 are arranged in parallel along the length direction of the precast composite wall panel 1. The pull-tab sheaths 7 contact the bracket bottom net 3-1. Inside the pull-tab sheaths 7, there is a formwork pull-tab 6, which is in the shape of a saber with a handle. It includes a pull-tab 6-1, made of high-strength materials such as stainless steel plates and galvanized steel plates. Its function is to tie the precast composite wall panel 1 and the integrated decorative board 4. During work, the pull-tab 6-1 passes through the pull-tab sheath 7 and the joint between two adjacent integrated decorative boards 4. One end of the pull-tab 6-1 is provided with an opposite-pull hole 6-4 for connecting with the back rib structure of the integrated board. The other end of the pull-tab 6-1 is provided with a handle 6-3. On the side of the handle 6-3 close to the pull-tab 6-1, there is a baffle 6-2. The handle 6-3 and the baffle 6-2 are located on the opposite outer sides of the precast composite wall panel 1.

[0089] The back rib structure of the integrated board is a component that restricts the formwork during the pouring of the concrete wall. Its basic function is to prevent the formwork from bulging during pouring. During use, it needs to be connected to the opposite formwork by bolts or other means. The back rib structure of the integrated board includes a back rib main body 5-1, made of lightweight and high-strength materials such as aluminum alloy and high-strength plastic. On both sides of the back rib main body 5-1 in the length direction, there are end plates 5-2 integrally connected. The end plates 5-2 are provided with connection holes 5-4. The back rib main body 5-1 and the end plates 5-2 form a "U" shape structure, with the opening facing the opposite side of the integrated decorative board 4. A back rib bottom plate envelope 5-3 is sleeved on the bottom of the back rib main body 5-1. The back rib bottom plate envelope 5-3 is made of rubber and PVC flexible materials. During the installation process, the connection hole 5-4 and the opposite-pull hole 6-4 are coaxial and locked by the pin 9.

[0090] A T-shaped caulking strip 8 is inserted into the gap between the bracket side frames 3-2 of two adjacent brackets 3. The T-shaped caulking strip 8 is prepared from soft materials such as pvc and rubber. The vertical part of the T-shaped caulking strip 8 is inserted into the gap to prevent the slurry from flowing out during concrete pouring.

[0091] On-site installation:

[0092] (1) The prefabricated composite wall panel 1 is hoisted into place, the temporary fixed support rods 1-2 are installed, the verticality of the wall is adjusted, and the steel bar system is checked, especially the flatness of the steel bar mesh near the non-removal formwork;

[0093] (2) Formwork-penetrating pull tab 6: Since the prefabricated composite wall panel 1 is integrally cast together with the component 7 during production, the formwork-penetrating pull tab 6 vertically penetrates the prefabricated composite wall panel 1 and the tie rod sheath 7 until it penetrates the decorative integrated panel 4. The pull tab 6-1 is provided with one end of a pull hole 6-4 extending outward. The position of the pull hole 6-4 corresponds to the position of the connection hole 5-4 and is locked by a pin 9;

[0094] (3) From bottom to top, install the first bracket 3: the bracket side frame 3-2 is close to the pull tab 6-1, the bracket bottom net 3-1 is tied, and the traditional process is to use iron wire or other binding tapes to tie it to the steel mesh at multiple points, that is, the bracket bottom net 3-1 is close to the steel mesh and firmly bound;

[0095] (4) Install other brackets in the same way. At this time, each bracket side frame 3-2 is close to the pull tab 6-1, and the bracket bottom mesh 3-1 is firmly tied to the steel mesh. If there is a corner, cut a section of the bracket bottom mesh 3-1 and splice it again to ensure that at least one bracket side frame 3-2 is temporarily fixed to the integrated plate.

[0096] (5) From bottom to top, install the integrated decorative board 4: the width L2 of the integrated board is consistent with the width L1 of the bracket. After the integrated board is embedded in the bracket 3, the pin is immediately inserted into the fixing ring 3-3 to temporarily fix the integrated decorative board 4;

[0097] (6) Similarly, install other integrated decorative panels 4; in short, the bracket 3 corresponds to the integrated decorative panel 4, that is, the integrated decorative panel 4 must be temporarily fixed by the bracket 3;

[0098] (7) Install T-shaped caulking strips 8: The caulking strips are soft sponges that can be easily cut and disconnected at the pull tab. They can be clamped directly during bracket installation or can be stuffed into the gap after the bracket is installed. In short, the caulking strips must be installed before installing the integrated panel to prevent leakage during concrete pouring.

[0099] (8) Install the back rib 5: The back rib is a key component to prevent the mold from expanding during concrete pouring. Its cross-sectional size is determined by the width and thickness of the integrated board and the longitudinal spacing of the pull tab arrangement; the end plate hole position is determined according to the wall thickness or the pull tab hole position; the back rib length = the width of the bracket; at this time, the back rib body 5-1, the pull tab 6-1, and the integrated decorative board 4 are locked to form a precise and stable exterior wall formwork;

[0100] (9) Install the pin 9: Align the back edges in sequence and wedge them in, which is a traditional process;

[0101] (10) At this point, the inner and outer wall formworks form a stable whole, and the concrete pouring cavity is formed;

[0102] (11) Note: In this example, only one side of the back rib system is set. If the thickness of the precast concrete composite wall is insufficient after calculation, we will adopt two solutions to ensure the stability of the inner wall formwork: one is to increase the baffle 6-2, and the other is to add an integrated back rib structure. The anchor point of the integrated back rib structure is the handle 6-3.

[0103] (12) Cavity casting concrete: traditional process; the anchor nails of the integrated panel have been cast together with the concrete;

[0104] (13) Curing and forming;

[0105] (14) Remove the outer back rib;

[0106] (15) Pull out the template pull tab 6;

[0107] (16) Shorten the temporary fixing ring 3-3;

[0108] (17) According to the traditional process requirements, the integrated board is filled and glued;

[0109] (18) Tear off the protective film on the integrated panel surface;

[0110] (19)Completion.

[0111] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the principle of the present invention, and they should also be considered to belong to the protection scope of the present invention.
