Description

Technical Field

[0001] The present invention relates to the field of building construction, in particular to an ultra-thin UHPC dry-hanging wall panel and a connection method thereof. Background Art

[0002] UHPC (UHPC), also known as Ultra High Performance Concrete (UHPC), is a new type of curtain wall material. Its ultra-high strength, toughness, and durability significantly improve the shortcomings of traditional concrete structures. It is essentially a new way to combine steel and concrete.

[0003] UHPC is widely used in exterior walls and pavements of auditoriums, hotels, clubs, shopping malls, airports, and other areas. It is also suitable for dry-hanging exterior wall applications in the construction industry. It offers a wide selection of designs and colors, allowing for flexible combinations. It is also resistant to wear, acid, heat, impact, compression, and flexure. It is also highly stain-resistant, with a non-porous surface that resists oil and water stains.

[0004] Existing UHPC panels are generally assembled using prefabricated connectors and fixed to external channel steel using screws. However, this method requires operators to install the panels from the back, requiring a large operating space to facilitate installation. The installation is difficult and inefficient, and requires a high level of on-site environment and the skill level of the construction workers. Summary of the Invention

[0005] The present invention provides an ultra-thin UHPC dry-hanging wall panel and a connection method thereof. The wall panel structure and the dry-hanging structure enable the wall panel to be installed so that a firm dry-hanging effect can be achieved by simply lifting the wall panel and then directly moving it horizontally and pressing it in. The installation process is extremely simple, there is no space requirement on the back of the panel, and personnel do not need to install on the back of the panel. Therefore, the requirements for the on-site environment and construction personnel are low, and the installation efficiency can be significantly improved.

[0006] An ultra-thin UHPC dry-hanging wall panel comprises a panel body and a dry-hanging frame; a dry-hanging body is embedded in the center of the back of the panel body; the dry-hanging body has an I-shaped radial cross-section, with convex wings at both ends, one end of which is embedded and fixed in the panel body, and the other end extends from the back of the panel body; the dry-hanging frame comprises a plurality of fixed vertical steels and a plurality of horizontal steels; the vertical steels and horizontal steels are crisscrossed to form a plurality of square dry-hanging surfaces according to set dimensions; a hung body is arranged in the center of the dry-hanging surface; an adjustable telescopic rod is respectively connected between the hung body and the vertical steels and horizontal steels that enclose the square dry-hanging surfaces; one end of the adjustable telescopic rod is fixedly connected to the hung body, and the other end is fixedly connected to a sliding sleeve; the sliding sleeve is detachably slidably mounted on the vertical steels and horizontal steels; the dry-hanging body is hung on the hung body.

[0007] The adjustable telescopic rod includes a first set of rods, a second set of rods, and a threaded rod threadedly connected to the first set of rods and the second set of rods; the thread direction of the threaded rod is opposite to that of the first set of rods and the second set of rods.

[0008] For the object to be hung and the hanging method, the following two implementation plans are adopted:

[0009] When the cam is in the closed position, the cam is engaged with the control wheel, and the control wheel is in the closed position, and the control wheel is in the closed position, and the control wheel is in the closed position, and the control wheel is in the closed position.

[0010] The front end edge of the convex wing that is plugged into the large sink groove is provided with a chamfered corner, and the rear end edge is provided with a beveled corner to facilitate the smooth rotation of the one-way rotating block.

[0011] The opening edge of the large sink is beveled to form a bell mouth to facilitate the insertion of the convex wing.

[0012] The convex wing is a regular polygon, and the inner wall of the large trough is also a regular polygon corresponding to the convex wing.

[0013] Among them, a connection method of ultra-thin UHPC dry hanging wall panels includes the following steps:

[0014] ① Assemble and fix vertical and horizontal steels according to design requirements and construction drawings;

[0015] ② Install the sliding sleeves at the outer ends of the adjustable telescopic rods of the hanging object on the vertical steel and horizontal steel respectively; adjust the length of the adjustable telescopic rods respectively so that the hanging object is located in the center of the dry noodles;

[0016] ③ Lift the plate body to face the dry hanging noodles; push the plate body parallel to the dry hanging noodles, and embed the dry hanging body into the large sink. During the embedding process, the convex wing pushes the one-way rotating block to deflect to the side of the bottom of the large sink, so that the convex wing smoothly passes the one-way rotating block and embeds into the bottom of the large sink;

[0017] ④ The one-way rotating block rotates back to vertical under the action of the torsion spring. Due to the stop of the stop convex block, the one-way rotating block clamps the convex wing at the bottom of the large sink and cannot escape, thereby achieving hanging and fixing.

[0018] Option 2: A plurality of U-shaped claw plates are evenly distributed around the center of the hung body on one side facing the plate body; the middle of the back side of the U-shaped claw plate is rotatably connected to the hung body, and a torsion spring is provided at the rotation point to keep the U-shaped claw plate opening inclined toward the center of the hung body; a through opening is provided on the side of the convex wing outside the plate body facing the plate body; an elastic covering is provided on the through opening; a channel is provided in the dry hanging body; the channel is connected to the through opening and leads to the outside world from the center of the plate body; when the other end of the dry hanging body approaches the hung body, it is inserted into the opening of each U-shaped claw plate and pushes each U-shaped claw plate to rotate so that the opening is vertical; concrete or gel is poured from the outside through the channel; the concrete or gel flows through the channel to the through opening and outwardly stretches the elastic covering layer, so that both sides of the convex wing are tightly against the inner side of the U-shaped claw plate, thereby achieving hanging and fixation.

[0019] Wherein, the channel is embedded with an internal threaded barrel at the front outlet of the plate body; a plug body with external threads is detachably screwed with the internal threaded barrel to close the channel.

[0020] The outer side surface of the convex wing is a regular hexagon, and the number of the U-shaped claw plates corresponds to the number of sides of the convex wing.

[0021] Among them, a connection method of ultra-thin UHPC dry hanging wall panels includes the following steps:

[0022] ① Assemble and fix vertical and horizontal steels according to design requirements and construction drawings;

[0023] ② Install the sliding sleeves at the outer ends of the adjustable telescopic rods of the hanging object on the vertical steel and horizontal steel respectively; adjust the length of the adjustable telescopic rods respectively so that the hanging object is located in the center of the dry noodles;

[0024] ③ Lift the plate body to face the dry hanging noodles; push the plate body parallel to the dry hanging noodles, insert the protruding wings of the dry hanging body into the openings of each U-shaped claw plate and push each U-shaped claw plate to rotate so that the opening is facing vertically;

[0025] ④ Pour concrete or gel from the outside through the channel; the concrete or gel flows through the channel to the opening and expands the elastic covering layer outward, so that both sides of the convex wings are tightly against the inner side of the U-shaped claw plate. After solidification, the U-shaped claw plates are simultaneously filled and covered by the expanded convex wings and cannot be rotated or detached, thereby achieving hanging and fixation.

[0026] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0027] 1. The ultra-thin UHPC dry-hanging wall panel of the present invention and its connection method enable the installation process to achieve a firm dry-hanging effect by simply lifting the wall panel and then directly pressing it in horizontally. The installation process is extremely simple, there is no space requirement on the back of the panel, and personnel do not need to install on the back of the panel. Therefore, the requirements for the on-site environment and construction personnel are low, which can significantly improve the installation efficiency.

[0028] 2. The dry hanging frame of the present invention adopts vertical steel and horizontal steel combined with adjustable telescopic rods to fix the hung object. By utilizing the adjustable length of the adjustable telescopic rods and the sliding characteristics of the sliding sleeves on the vertical steel and horizontal steel, the position of the hung object can be adjusted according to the on-site conditions, thereby ensuring installation accuracy. The installation and adjustment methods are extremely simple and convenient.

[0029] 3. Embodiment 1 of the present invention utilizes the method of being embedded and matched with the outer end of the large sink trough and cleverly designs a one-way rotating structure. By utilizing the one-way rotating block, the stop protrusion and the torsion spring, the design can be realized simply and at low cost. By utilizing the structural characteristics of the one-way rotating structure and the convex wing, the one-way rotating block is pushed to deflect toward the side of the groove bottom during the process of inserting the outer end of the dry hanging body into the large sink trough, so that the other end of the dry hanging body can be smoothly inserted into the bottom of the large sink trough; and after the convex wing at the other end of the dry hanging body passes over the one-way rotating block, the one-way rotating block rotates to a vertical position under the action of the torsion spring. Due to the stop protrusion, the one-way rotating block clamps the convex wing to the bottom of the large sink trough, thereby realizing hanging and fixing; this method realizes the effect that the plate body can be hung and engaged by pushing forward and the engaging structure is firm. The design and operation action is simple and easy, and the structural design is firm and stable.

[0030] 4. Embodiment 2 of the present invention utilizes the structural characteristics of the U-shaped claw plate and is designed to be inclined in a static state, so as to facilitate the outer end of the dry hanging body to be first inserted into the opening of each U-shaped claw plate during the feeding process, and as the feeding continues, each U-shaped claw plate is pushed to rotate so that the opening is facing vertically; thereby, the U-shaped claw plate produces a preliminary clamping of the dry hanging body, and then concrete or gel is poured from the outside through the channel; the concrete or gel flows through the channel to the opening and stretches the elastic covering layer outward, so that the front and rear surfaces of the convex wings are tightly against the inner side surfaces of the U-shaped claw plate. After solidification, the U-shaped claw plates are simultaneously filled and covered by the expanded convex wings and cannot be rotated or detached, thereby achieving hanging and fixing; this method also achieves the effect that the plate body can be hung and engaged by forward advancement and the engaging structure is firm, the design and operation action is also simple and easy, and the structural design is also firm and stable.
