Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a lightweight wall panel wall structure system and a construction method thereof. Background Art

[0002] The modernization of the construction industry is the development trend of my country's construction industry today. The industrialized production of building components and prefabricated installation are the basic requirements of the modernization of the construction industry. Walls are an important part of house buildings, and the prefabricated installation of walls is an inevitable development of house construction methods. In recent years, various building wall panels have developed rapidly, but they are relatively backward in the construction system, which makes the wall panels have certain problems and shortcomings, mainly manifested in cracks in the wall panel seams, cracks between the wall panels and the main structure, unreliable connections with the main structure that cannot meet the seismic requirements, and poor firmness in the installation of doors and windows. Summary of the invention

[0003] The present invention provides a lightweight wall panel wall structure system and a construction method thereof, which utilizes pre-buried or post-buried connecting parts to form reliable connections between wall panels, between wall panels and main structures, and between wall panels and doors and windows and various accessories, thereby forming an integral wall with good integrity, excellent seismic performance, great rigidity and small deformation within the wall plane, thereby solving many problems and shortcomings existing in existing lightweight wall panel walls.

[0004] The technical solution of the present invention is:

[0005] A method for constructing a lightweight wall panel structure system comprises the following steps:

[0006] Pre-embed or post-embed connectors in wall panels;

[0007] A wall is formed by connecting multiple wall panels into one body through pre-buried or post-buried connectors;

[0008] The wall is assembled from wall panels, and the wall panels and the main structure are connected into one by pre-buried or post-buried connectors;

[0009] In a wall composed of wall panels, the wall panels, doors, windows, and various accessories are connected into one through pre-buried or post-buried connectors.

[0010] The connecting parts are embedded in the wall panels, and are cast into the wall panels when the wall panels are produced.

[0011] The post-embedded connector in the above-mentioned wall panel has a notch on the finished wall panel, and the connector is cast in the notch using a waterproof gypsum-based material.

[0012] The lightweight wall panel wall structure system constructed by the above method is characterized in that it is assembled from multiple wall panels with pre-embedded or post-embedded connecting parts, and adjacent wall panels are connected by the connecting parts to form a whole wall; the wall panels are connected to the main structure, doors and windows and various accessories through the pre-embedded or post-embedded connecting parts.

[0013] A notch is provided at the position where the connecting member is buried behind the wall panel, and the connecting member is cast in the notch using a waterproof gypsum-based material.

[0014] The spacing between the above-mentioned connecting parts is ≤1.5 times the width of the wall panel.

[0015] The above-mentioned connecting piece is composed of an anchor plate for connection and an anchor steel bar for ensuring the anchoring force, and the anchor plate is fixedly connected to the anchor steel bar.

[0016] Compared with the prior art, the lightweight wall panel wall structure system and construction method provided by the present invention have the following beneficial effects:

[0017] 1. In the prior art, the connection between wall panels relies on the mortise and tenon connection method. In order to ensure a reliable connection between wall panels, grouting is required in a very narrow gap. This method is difficult to control the construction quality and has low work efficiency. In addition, it is known from engineering knowledge that the tensile strength of mortar is very low. It is generally believed in engineering that it does not have effective tensile strength and cannot ensure the pulling effect between wall panels. Therefore, the problem of cracking in the board seams has never been well solved. The lightweight wall panel wall construction system provided by the present invention is a wall assembled from wall panels. The wall panels are connected to each other through corresponding connectors. The reliability of this connection is sufficient to meet the requirements of wall integrity and force, especially for deformation of the main structure and cracking caused by shrinkage and expansion due to changes in temperature and humidity. It is very effective. It can be said that it fundamentally solves the engineering problem of cracking in the wall panel seams.

[0018] 2. When the lightweight wall panels in the prior art are connected to the main structure or doors and windows, they are generally connected by means of clips. The clip connection can only limit the displacement outside the wall panel plane but cannot ensure the displacement within the wall panel plane. In addition, the clips are easy to loosen and cannot ensure a reliable connection. However, the present invention pre-embeds or post-embeds the connector on the wall panel, making the connector a stable connection point of the wall. The connector is connected to the main structure or doors, windows and other accessories by bolts or welds to form a reliable connection. This solves the problems existing in the wall panels of the prior art, such as the fixation is not reliable enough and cannot meet the earthquake resistance requirements. In particular, the exterior walls of the building have higher reliability requirements for the connection between the wall panels and the main structure. The traditional wall construction method generally cannot meet the requirements. The present construction method is sufficient to meet the requirements through the connection of the connector.

[0019] 3. The wall composed of several wall panels connected by connectors is subjected to overall force. Generally, the height and width of the wall are close. According to general mechanical knowledge, such a wall has very little deformation in the wall plane and is almost a rigid body, and will hardly produce bending moment to the lower supporting structure, which provides a reliable engineering solution for setting up walls in beamless areas of the floor.

[0020] 4. When the connector is embedded in the wallboard, the connector is cast in the notch of the wallboard using waterproof gypsum-based materials. The waterproof gypsum-based materials are used for casting. First, the quick setting property of gypsum is used to realize immediate embedding. Second, the micro-expansion of gypsum during hardening makes it difficult to crack at the joint with the original board material. Third, the strength of gypsum with appropriate proportion is generally much higher than that of lightweight wallboard materials, which is enough to meet the anchoring requirements of the connector. In addition, the waterproof gypsum can meet the water resistance requirements. In order to further ensure that there is sufficient bonding force between the post-cast gypsum-based materials and the wallboard materials, the interface strengthening binder can also be pre-coated on the connection interface.

[0021] 5. The traditional wall panel connection method is basically an empirical method. There is no clear calculation method to verify the reliability of the connection in engineering design, and it can only be applied within the scope specified by experience. The pre-embedded or post-embedded connector in the present invention has a design calculation method specified in the "Concrete Structure Design Code" (GB50010) and other national standards, which can verify the reliability of its force, and through reliable design calculation, it is not limited by the scope of application.

[0033] Combine the following Figure 1-9 , a specific embodiment of the present invention is described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0034] Embodiment 1:

[0035] The present invention provides a method for constructing a lightweight wall panel wall structure system, comprising the following steps:

[0036] Pre-embed or post-embed connectors in wall panels;

[0037] A wall is formed by connecting multiple wall panels into one body through pre-buried or post-buried connectors;

[0038] The wall is assembled from wall panels, and the wall panels and the main structure are connected into one by pre-buried or post-buried connectors;

[0039] In a wall composed of wall panels, the wall panels, doors, windows, and various accessories are connected into one through pre-buried or post-buried connectors.

[0040] Furthermore, the wall panels are pre-embedded with connectors, which are cast into the wall panels during production.

[0041] Furthermore, the connecting piece is embedded in the wall panel, a notch is opened on the finished wall panel, and the connecting piece is cast in the notch using a waterproof gypsum-based material.

[0042] The present invention provides a method for constructing a lightweight wall panel wall structure system. The wall panel 1 is suitable for various materials, including various concretes and other cement-based and gypsum-based materials. The wall panel 1 is also suitable for various cross-sectional forms, including solid panels, hollow panels, and sandwich panels.

[0043] like Figure 1 , Figure 2 , Figure 3 As shown, the wall panel 1 is generally produced according to certain relatively common standardized dimensions, and during production, the connecting members 2 are pre-buried at predetermined positions to form the wall panel 1 having the connecting members 2 .

[0044] like Figure 4 As shown, when the wall panel 1 is installed on site, individual wall panels need to be cut according to actual conditions, and the cut edges no longer have pre-buried connectors 2. At this time, the connectors 2 are embedded at specific locations where they are needed. The specific method is as follows: a notch 7 is opened at a specific location on the wall panel 1, and the connector 2 is placed in the notch 7. The connector 2 is then poured into the notch 7 using a waterproof gypsum-based material 8, and the quick-setting property of the waterproof gypsum-based material is utilized to achieve ready-to-use embedding.

[0045] like Figure 5 As shown, the connecting member 2 is composed of an anchor plate 5 and an anchoring steel bar 6 connected thereto. The function of the anchor plate 5 is to facilitate the various connections mentioned above, and the function of the anchoring steel bar 6 is to ensure that the anchoring force of the connecting member 2 on the wall panel 1 meets the force requirements.

[0046] like Figure 6 As shown, the wall of the house is composed of a plurality of wall panels 1, and the adjacent wall panels 1 are connected to each other through welds 9 using connectors 2 pre-buried or post-buried at corresponding positions. The wall panels 1 are connected to each other to form an integrally stressed wall panel wall. In this case, the spacing of the connectors 2 pre-buried or post-buried at the edges of the wall panels 1 is controlled within 1.5 times the width of the wall panels. After the wall panels 1 are connected to each other, the wall panels between the connectors 2 are basically in a rigid body stress state, and the slight deformation of the wall panels can be ignored in engineering.

[0047] like Figure 7 As shown, the wall composed of multiple wall panels 1 can be connected to each other by welds 9 using connectors 2 at corresponding positions of the wall panels 1 and connectors 10 of the main structure. After the connection, the whole wall composed of the wall panels 1 can form a reliable connection with the main structure.

[0048] like Figure 8 As shown, holes for installing doors, windows 4 and various accessories need to be reserved on the entire wall, and connectors 2 are pre-buried or post-buried on the edges of the wall panels 1 around the holes. Reliable connection can be achieved with the connectors 2 and accessories such as doors and windows, so that the doors, windows 4 and various accessories form a firm and reliable connection with the wall composed of the wall panels 1.

[0049] like Fig. 9 As shown, the connecting piece used to connect the wall panel 1 and the main structure 3 is not limited to Figure 5 The connecting member 2 shown in the figure may also be in the form of a post-embedded anchor bolt 12, where a circular hole 11 is opened at a specific position of the wall panel, and the anchor bolt 12 is placed in the circular hole 11, and the bolt is post-embedded in the wall panel 1 after pouring the waterproof gypsum-based material 8. The part of the anchor bolt 12 embedded in the wall panel 1 plays an anchoring role, and the exposed part plays a connecting role. Such a post-embedded anchor bolt 12 can achieve a reliable connection with the main structure.

[0050] In the prior art, the connection between wall panels relies on the mortise and tenon connection method, which requires grouting in a very narrow gap. It is difficult to ensure the stability of the connection by grouting. Since the tensile strength of the mortar is almost zero, the integrity of the connection between the two panels cannot be guaranteed under special stress conditions, and the problem of cracking in the panel seams has never been well solved. The lightweight wall panel wall construction system provided by the present invention is a wall assembled from wall panels, and the wall panels are connected to each other through corresponding connectors. The reliability of this connection is sufficient to meet the requirements of wall integrity and stress, especially for deformation of the main structure and cracking caused by shrinkage and expansion due to changes in temperature and humidity. It is very effective, which can be said to fundamentally solve the engineering problem of cracking in wall panel seams.

[0051] Several lightweight wall panels are connected to each other by pre-buried or post-buried connectors to form an integrally stressed wall panel wall. Each wall is generally similar in height and width. From general mechanics knowledge, the wall can be regarded as a non-deformable rigid body within the plane of the wall, and basically no bending moment will be generated on the lower supporting structure, providing a reliable engineering solution for setting up walls in beamless areas of the floor.

[0052] The prior art lightweight wall panels lack a stable connection point when connected to the main structure or doors and windows. In the present invention, when the wall panels are connected to the main structure or doors and windows, the connection piece is a stable fixing point, which can form a reliable connection between the wall panel wall and the main structure and between the wall panel wall and accessories such as doors and windows, and well solve the problems existing in the prior art wall panels such as poor fixing firmness and failure to meet earthquake resistance requirements.

[0053] Embodiment 2:

[0054] The present embodiment provides a lightweight wall panel wall structure system, which is assembled from multiple wall panels 1 with pre-embedded or post-embedded connecting parts 2, and adjacent wall panels 1 are connected by the connecting parts 2 to form a whole wall; the wall panels 1 are connected to the main structure 3, doors and windows 4 and various accessories through the pre-embedded or post-embedded connecting parts 2.

[0055] Furthermore, a notch is provided at the position where the connecting member 2 is buried at the rear of the wallboard 1 , and the connecting member 2 is cast in the notch 7 using a waterproof gypsum-based material 8 .

[0056] In the present invention, the wall panel 1 is generally produced according to a certain relatively common standardized size. During production, the connecting piece 2 is pre-embedded at a predetermined position to form the wall panel 1 with the connecting piece 2. The wall panel 1 and the pre-embedded connecting piece 2 are cast into one piece. Figure 4As shown, when the wall panel 1 is installed on site, individual wall panels need to be cut according to actual conditions, and the cut edges no longer have pre-buried connectors 2. At this time, the connectors 2 are buried at specific locations where they are needed. The specific method is: a notch 7 is opened at a specific location on the wall panel 1, and the connector 2 is placed in the notch 7. The connector 2 is then poured into the notch 7 using a waterproof gypsum-based material 8, and the quick-setting property of the waterproof gypsum-based material 8 is used to achieve immediate embedding and use.

[0057] Furthermore, the multiple wall panels 1 are assembled through the connecting parts 2 to form an assembled integral wall. In this case, the spacing of the connecting parts 2 pre-embedded or post-embedded in the edge of the wall panel 1 is controlled within 1.5 times the width of the wall panel. After the wall panels 1 are connected to each other, the wall panels between the connecting parts 2 are basically in a rigid body stress state. Under the influence of factors such as deformation of the main structure, temperature and humidity, and shrinkage of materials, the deformation of the wall panels is very small and can be ignored in engineering. There is no cracking problem without deformation. It can be said that this lightweight wall panel wall structure system fundamentally solves the engineering problem of cracking in the wall panel seams.

[0058] Furthermore, the above-mentioned integral walls of the various parts of the house are assembled from multiple blocks, and each wall is generally of similar height and width. From general mechanics knowledge, the wall can be regarded as an undeformed rigid body within the plane of the wall, and basically no bending moment will be generated on the lower supporting structure, which provides a lightweight wall panel wall structure system for setting up walls in beamless areas of the floor.

[0059] Furthermore, the above-mentioned connecting member 2 is composed of an anchor plate 5 and an anchor steel bar 6 connected thereto. The function of the anchor plate 5 is to facilitate the realization of the above-mentioned various connections, and the function of the anchor steel bar 6 is to ensure that the anchoring force of the connecting member 2 on the wall panel 1 meets the force requirements. The method of pre-embedded or post-embedded connecting members has design calculation methods specified in national standards such as the "Code for Design of Concrete Structures" (GB50010), which can verify the reliability of its force.

[0060] In the present invention, the anchor plate 5 is stamped from a thin steel plate. When the wall panel 1 is produced, the anchor steel bar 6 is embedded in the wall panel 1 material when the connecting piece 2 is embedded. That is, the anchor steel bar 6 is prefabricated inside the wall 1 to increase the anchoring force of the wall 1. The anchor plate 5 is fixedly connected to the anchor steel bar 6. At the same time, the anchor plate 5 is fitted with the side of the wall panel 1. The anchor plate 5 is used to connect with adjacent wall panels 1, the main structure 3, and various accessories of doors and windows.

[0061] Working principle of the present invention:

[0062] When adjacent wall panels 1 are connected, the specific connection process is as follows:

[0063] If there are pre-buried connectors 2 on opposite sides of adjacent wall panels 1, the connection between adjacent wall panels 1 is completed by welding the anchor plate 5 on one side of one wall panel 1 to the anchor plate 5 on the other side of the wall panel 1. If there are no pre-buried connectors 2 on all or part of the opposite sides of adjacent wall panels 1, the connectors 2 are post-buried at the positions where the connectors 2 are missing. When post-buried connectors 2 are buried, anchor steel bars 6 are cast into the gaps 7 using waterproof gypsum-based materials 8, and the anchor plates 5 fit the side edges of the wall panels 1. After post-buried, the anchor plates 5 on one side of one wall panel 1 are welded to the anchor plates 5 on the other side of the wall panel 1 to complete the connection between adjacent wall panels 1. Finally, multiple wall panels 1 are connected to form a whole wall.

[0064] When the wall panel 1 is connected to the door and window 4, as well as various accessories, the specific connection process is as follows:

[0065] Holes for installing doors, windows 4 and various accessories need to be reserved on the entire wall. Connectors 2 are pre-buried or post-buried on the edges of the wall panels 1 around the holes. Reliable connection can be achieved between the connectors 2 and accessories such as doors and windows, so that the doors, windows 4 and various accessories form a firm and reliable connection with the wall composed of the wall panels 1.

[0066] When the wall panel 1 is connected to the main structure 3, the specific connection process is as follows:

[0067] Determine whether to cut the wall panel 1 according to the actual situation. Figure 7 As shown, when one side of the uncut wall panel 1 is connected to the main structure 3, due to the pre-embedded connector 2, the anchor steel bar 6 of the connector 2 is pre-embedded inside the wall panel 1, and the anchor plate 5 of the connector 2 is welded to the main structure connector 10 as a whole. When one side of the cut wall panel 1 is connected to the main structure 3, due to the absence of the pre-embedded connector 2, the connector 2 needs to be post-embedded at a specific position. The post-embedded connector 2 means that a notch 7 is opened at a specific position on the wall panel 1, the connector 2 is placed in the notch 7, and the anchor steel bar 6 is cast in the notch 7 using a waterproof gypsum-based material 8, and the anchor plate 5 fits the side of the wall panel 1 to weld the anchor plate 5 to the main structure 3 as a whole.

[0068] like Fig. 9 As shown, the connecting piece used to connect the wall panel 1 and the main structure 3 is not limited to Figure 5 The connecting member 2 shown in the figure may also be in the form of a post-embedded anchor bolt 12, where a circular hole 11 is opened at a specific position of the wall panel, and the anchor bolt 12 is placed in the circular hole 11, and the bolt is post-embedded in the wall panel 1 after pouring the waterproof gypsum-based material 8. The part of the anchor bolt 12 embedded in the wall panel 1 plays an anchoring role, and the exposed part plays a connecting role. Such a post-embedded anchor bolt 12 can achieve a reliable connection with the main structure.

[0069] To sum up, compared with the prior art, a lightweight wall panel wall structure system and a construction method thereof of the present invention, by pre-embedding or post-embedding connecting parts in the wall panels, utilizes the connecting parts to form reliable connections between wall panels, between wall panels and main structures, between wall panels and doors and windows, and between various accessories, thereby forming an integral wall with good integrity, excellent seismic performance, great stiffness and small deformation within the wall plane, thereby solving many problems and shortcomings existing in existing lightweight wall panel walls.

[0070] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
