Description

Technical Field

[0001] The present invention belongs to the technical field of construction, and particularly relates to a synchronous construction method for integrating building and decoration thermal insulation. Background Art

[0002] With the rapid development of technology, the construction industry is gradually moving towards energy conservation, environmental protection, and fast construction speed. As a result, prefabrication technology has emerged, that is, prefabricating floor slabs and walls in the factory and then performing modular assembly at the construction site. This construction method greatly improves construction efficiency and cleans the site environment. However, due to the relatively weak mechanical properties of the connection parts, the integrity of the building is reduced, so most still adopt the traditional construction methods of formwork support, pouring, and formwork removal.

[0003] Some also use non-removable thermal insulation formwork as the outer formwork. At the position of the wall to be constructed, a steel bar grid is tied. An inner formwork is supported on the inner side of the steel bar grid, and an outer formwork is supported on the outer side. The outer formwork and the inner formwork are tensioned to form a pouring cavity. Concrete is poured into the pouring cavity. After the concrete is cured and formed, the inner formwork is removed to form a wall, so that the outer formwork becomes a part of the wall. This construction method not only avoids the removal of the outer formwork but also realizes the synchronous construction of the thermal insulation layer and the wall, thus saving the independent construction process of the thermal insulation layer after the wall is formed. However, the inner formwork still needs to be supported and removed, and the tying of the steel bar grid requires arranging vertical steel bars and horizontal steel bars according to the drawings and then firmly tying the arranged vertical steel bars and horizontal steel bars together. This not only reduces the production speed of the steel bar grid but also requires professional steel bar workers, increasing labor costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a synchronous construction method for integrating building and decoration thermal insulation, which can realize the synchronous construction of building walls and internal and external decorations, reduce construction processes, and facilitate significantly shortening the construction period on the premise of ensuring the integrity of the building.

[0005] To solve the above technical problem, the technical solution of the present invention is: designing a synchronous construction method for integrating building and decoration thermal insulation, which is characterized by including the following steps:

[0006] (1) Manufacturing a steel bar grid: arranging two or more keels in sequence along the extension direction of the wall to be built. The keels used include a first vertical rib and a second vertical rib, and the first vertical rib and the second vertical rib are arranged side by side inside and outside in sequence. It also includes two or more horizontal ribs arranged vertically in sequence. One end of the horizontal rib is fixed to the first vertical rib, and the other end is fixed to the second vertical rib. A card slot is provided on the horizontal rib; the inner end wall of the first vertical rib is located in a first plane, and the outer end wall of the second vertical rib is located in a second plane. The first plane and the second plane are arranged in a parallel manner. Transverse steel bars are clamped in the card slots located on the same straight line in all the keels to form a steel bar grid;

[0007] (2)Formwork erection: Fix the interior panel in the first plane and the exterior panel in the second plane, and a casting cavity is formed between the interior panel and the exterior panel; the interior panel has an interior layer located on the innermost side, the exterior panel has an exterior layer located on the outermost side, and a thermal insulation layer is also provided in the exterior panel;

[0008] (3)Casting: Fill the casting cavity with slurry. After the slurry is cured and formed, it jointly constitutes a wall with the interior panel and the exterior panel.

[0009] Preferably, in step (2), the interior panel and the exterior panel are fixed by a fixture. The fixture includes a connecting beam, one end of the connecting beam is connected to the first clamping arm, and the other end is connected to the second clamping arm. The first clamping arm is clamped on the inner wall of the interior panel, and the second clamping arm is clamped on the outer wall of the exterior panel.

[0010] Preferably, the connecting beam is threadedly connected to the first clamping arm or / and the second clamping arm.

[0011] Preferably, a first connecting groove is formed on the outer wall of the interior panel, and a second connecting groove is formed on the inner wall of the exterior panel. The inner end of the first connecting groove is larger than the outer end, and the outer end of the second connecting groove is larger than the inner end.

[0012] Preferably, both the first connecting groove and the second connecting groove are dovetail grooves.

[0013] Preferably, in the keel of step (1), N card slots are formed on the same horizontal rib. The N card slots are sequentially named the nth card slot from the inside to the outside. N is a natural number, and n is a natural number less than N + 1.

[0014] Preferably, the inner end wall of the first vertical rib has a first supporting surface, and the outer end wall of the second vertical rib has a second supporting surface. The second supporting surface is parallel to the first supporting surface.

[0015] Preferably, M transverse steel bars are connected to the same horizontal rib, and each transverse steel bar is located in a different card slot. M is a natural number and M ≤ N.

[0016] Preferably, N ≤ 6.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This construction method uses keels with a specific structure, which not only defines the installation positions of the interior panel and the exterior panel and plays a role in supporting the interior panel and the exterior panel, but also uses the interior panel with an interior layer as a non-removable inner formwork and the exterior panel with an exterior layer as a non-removable outer formwork, and together with the slurry cast on-site, constructs a wall, realizing the cast-in-place construction of the wall with its own interior layer and exterior layer. While maintaining the integrity of the building, it avoids multiple processes such as decoration and insulation; it also plays the role of vertical steel bars in the steel bar grid, and at the same time uses the card slots to restrict the installation positions of the horizontal steel bars, simplifies the installation method of the horizontal steel bars, improves the production speed of the steel bar grid, reduces the skill requirements for production workers, and is conducive to reducing labor costs; jointly shortens the construction period.

[0019] 2. Since a fixture is used to fix the interior panel and the exterior panel, it can not only achieve the rapid fixation of the interior panel and the exterior panel, but also facilitate repeated use, which is conducive to reducing the cost of construction consumables.

[0020] 3. Since the connecting beam is connected to the first clamping arm and the second clamping arm by a threaded connection method, the distance between the first clamping arm and the second clamping arm can be adjusted, which is convenient for the disassembly of the fixture after the wall is shaped.

[0021] 4. Since a first connecting groove is provided on the outer wall of the interior panel and a second connecting groove is provided on the inner wall of the exterior panel, the inner end of the first connecting groove is larger than the outer end, and the outer end of the second connecting groove is larger than the inner end. On the one hand, the interior panel and the exterior panel can increase the contact area with the slurry and increase the connection strength; on the other hand, they can form a wedge-shaped insertion structure with the slurry, further enhancing the connection strength and improving the integrity of the formed wall.

[0022] 5. Since the inner end wall of the first vertical rib has a first support surface and the outer end wall of the second vertical rib has a second support surface, and the second support surface is parallel to the first support surface, it can increase the contact area between the keel and the interior panel and the exterior panel and play a more stable supporting role.

[0023] 6. Since two adjacent interior panels are connected by a first tongue-and-groove joint and two adjacent exterior panels are connected by a second tongue-and-groove joint, the joint seam is zigzag, which increases the resistance to the leakage of the slurry, avoids the leakage of the slurry, and prevents the interior layer and the exterior layer from being soiled.

[0024] 7. Since M horizontal steel bars are connected to the same horizontal rib and each horizontal steel bar is located in a different card slot, a more dense steel bar grid can be prepared, which is conducive to enhancing the strength of the cast wall and improving the construction quality of the building.

[0025] 8. The present invention uses marble, tiles or plates coated with decorative coatings as the formwork without demolition. While adopting the traditional casting construction, the construction of functional layers such as thermal insulation and decoration is completed simultaneously, reducing the construction procedures, greatly shortening the construction period, and facilitating the popularization and application in this field.

DETAILED DESCRIPTION OF THE INVENTION

[0034] The present invention will be further described in detail below in conjunction with the drawings and the specific embodiments.

[0035] In the present invention, the side close to the indoor space is defined as the inner side, and correspondingly, the other side far from the indoor space is defined as the outer side; the end far from the ground is defined as the upper end or the top end, and correspondingly, the other end close to the ground is defined as the lower end or the bottom end.

[0036] The construction steps of the present invention are as follows:

[0037] (1) Fabricating the steel bar grid: As Figure 1 shown, two or more keels 2 are arranged in sequence along the extension direction of the wall to be built. As Figure 2As shown, the first vertical rib 21 and the second vertical rib 22 are provided in the used keel 2. The first vertical rib 21 and the second vertical rib 22 are arranged side by side inside and outside in sequence. The inner end wall of the first vertical rib 21 has a first support surface, and the outer end wall of the second vertical rib 22 has a second support surface. The second support surface is parallel to the first support surface. Seven horizontal ribs 23 are arranged in sequence from top to bottom between the first vertical rib 21 and the second vertical rib 22. One end of the horizontal rib 23 is fixed to the first vertical rib 21, and the other end is fixed to the second vertical rib 22, making the overall shape of the keel 2 trapezoidal. The inner end walls of all the first vertical ribs 21 are located in the first plane, and the outer end walls of all the second vertical ribs 22 are located in the second plane. The first plane and the second plane are arranged in a parallel state. A card slot 24 is provided on the horizontal rib 23, and a transverse steel bar 1 is clamped in the card slots 24 that are located on the same straight line in all the keels 2 to form a steel bar grid.

[0038] (2)Formwork erection: As Figure 3 shown, the interior trim panel 4 is fixed in the first plane, and the exterior trim panel 3 is fixed in the second plane. A casting cavity 5 is formed between the interior trim panel 4 and the exterior trim panel 3; the used interior trim panel 4 has an interior layer 43 located on the innermost side, and the exterior trim panel 3 has an exterior layer 34 located on the outermost side. A heat insulation layer 33 is also provided in the exterior trim panel 3.

[0039] (3)Casting: Fill the casting cavity 5 with slurry. After the slurry is cured and formed, it jointly forms a wall with the interior trim panel 4 and the exterior trim panel 3.

[0040] To facilitate the fixing operation of the interior trim panel 4 and the exterior trim panel 3, in step (2), the interior trim panel 4 and the exterior trim panel 3 are clamped by a fixture 6. As Figure 7 shown, a connecting beam 63 is provided in the fixture 6. One end of the connecting beam 63 is threadedly connected to the first clamping arm 61, and the other end is threadedly connected to the second clamping arm 62, which is convenient for adjusting the distance between the first clamping arm 61 and the second clamping arm 62. By changing the relative positions of the first clamping arm 61 or the second clamping arm 62 on the connecting beam 63, the first clamping arm 61 is clamped on the inner wall of the interior trim panel 4, and the second clamping arm 62 is clamped on the outer wall of the exterior trim panel 3, realizing the relative fixation of the interior trim panel 4 and the exterior trim panel 3 on the keel 2. After the cast slurry is cured and formed, by rotating the connecting beam 63, the distance between the first clamping arm 61 and the second clamping arm 62 is enlarged, which is convenient for removing the fixture 6 for the next use. In addition to using this fixture 6, other methods can also be used to fix the interior trim panel 4 and the exterior trim panel 3. For example, the inner wall of the interior trim panel 4 is squeezed from the inside by a support frame, so that the outer wall of the interior trim panel 4 is closely attached to the keel 2; the outer wall of the exterior trim panel 3 is squeezed from the outside by another support frame, so that the inner wall of the exterior trim panel 3 is closely attached to the keel 2. The fixation of the interior trim panel 4 and the exterior trim panel 3 can also be realized in the same way.

[0041] To increase the bonding force between the interior trim panel 4 and the exterior trim panel 3 and the slurry and enhance the integrity of the built wall, as Figure 4As shown, a first dovetail groove 41 is formed on the outer wall of the interior trim panel 4, and a second dovetail groove 31 is formed on the inner wall of the exterior trim panel 3. On the one hand, it can increase the contact area between the interior trim panel 4 and the exterior trim panel 3 and the slurry, and on the other hand, it can form a wedge-shaped insertion structure with the solidified slurry to enhance the connection strength between the two. In addition to using the dovetail groove structure, as Figure 6 shown, a connecting groove with a "convex" cross-section can also be used. In short, as long as the first connecting groove formed on the outer wall of the interior trim panel 4 has its inner end larger than the outer end, and the second connecting groove formed on the inner wall of the exterior trim panel 3 has its outer end larger than the inner end, the above-mentioned wedge-shaped insertion structure can be achieved. As Figure 5 shown, two adjacent interior trim panels 4 are connected by a first tongue-and-groove 42, and two adjacent exterior trim panels 3 are connected by a second tongue-and-groove 32, so that the tongue-and-groove joints are in a zigzag shape to increase the resistance to slurry leakage, avoid slurry leakage, and prevent the interior layer 43 and the exterior layer 34 from being soiled. Of course, as for the specific shapes of the first tongue-and-groove 42 and the second tongue-and-groove 32, they can be in an "L" shape or a "V" shape, or other shapes, as long as they are tongue-and-grooves, and no specific requirements are made for their shapes.

[0042] In this embodiment, 3 card slots 24 are correspondingly formed on each transverse rib 23. The 3 card slots 24 are sequentially named the first card slot, the second card slot, and the third card slot from the inside to the outside, and the card slots 24 are formed on the upper end wall of the transverse rib 23. After the keels 2 are arranged as required above, for all the transverse ribs 23 in the same row, their first card slots are commonly located on the first horizontal straight line, their second card slots are commonly located on the second horizontal straight line, and their third card slots are commonly located on the third horizontal straight line. The first straight line, the second straight line, and the third straight line are parallel to each other. So as to insert a transverse steel bar 1 into the first card slot on the first horizontal straight line, insert a transverse steel bar 1 into the second card slot on the second horizontal straight line, and insert a transverse steel bar 1 into the third card slot on the third horizontal straight line. The number of assembled transverse steel bars 1 in the same transverse rib 23 can be 1, that is, only installed in the second card slot; it can also be 2, that is, installed in the first card slot and the third card slot respectively; it can also be 3, that is, transverse steel bars 1 are installed in the first card slot, the second card slot, and the third card slot. The specific number determines the fineness of the steel bar grid. In addition to 3 in the above-mentioned embodiment, the number N of card slots 24 formed on the same transverse rib 23 can also be a natural number less than 7, specifically, it can be a certain natural number among 1, 2, 3, 4, 5, and 6. In addition to 2 in the above-mentioned embodiment, the number M of transverse steel bars 1 inserted in the same transverse rib 23 can also be flexibly adjusted according to the total number of floors of the building to be constructed. If the number of floors is large, it is larger, and if the number of floors is small, it is smaller. Specifically, it can be any natural number from 1 to N.

[0043] The above first, second, etc. are all auxiliary means used for clear description and are not specific limitations on the structure. The so-called exterior decoration layer can be an exterior paint layer, wall tiles or marble slabs, and the interior decoration layer can be calcium silicate board, marble slabs or wall tiles.

[0044] The above is only a preferred embodiment of the present invention and is not a limitation on the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
