Description

Technical Field

[0001] This invention relates to the field of curtain wall construction technology, and in particular to a curtain wall connector structure and its construction method. Background Technology

[0002] With the promotion of green buildings and ultra-low energy buildings, projects using curtain wall structures for exterior walls are increasing. In ultra-low energy buildings, curtain wall construction typically takes place after the main structure concrete is poured, usually during the main structure reinforcement binding stage. First, the curtain wall embedded parts are installed according to the drawings. Then, integrated silicon graphene insulation boards are laid on the outside of the main structure, followed by the pouring of the main structure. The curtain wall embedded parts need to be pre-embedded before pouring. Later, to install the curtain wall transition parts and keel, the insulation board at the embedded part location needs to be removed. However, existing technology has the following problems: because the embedded parts are obscured by the insulation board, and there are errors in the installation of the embedded parts, it is difficult to accurately locate the area for removing the insulation board later, easily leading to over-removal or under-removal of the insulation board, making it difficult to improve construction efficiency; over-removal of the insulation board can also result in the inability to effectively guarantee the quality of subsequent insulation construction, easily forming thermal bridges between the curtain wall keel and the main structure, affecting the overall insulation performance of the building. Summary of the Invention

[0003] The purpose of this invention is to provide a curtain wall connector structure and its construction method, which can accurately locate the embedded part from the outside of the insulation board, accurately define the range of the notch to be removed from the insulation board, and improve the efficiency of curtain wall construction.

[0004] To solve the above-mentioned technical problems, the embodiments of the present invention provide a technical solution as follows: a curtain wall connector structure, comprising: an embedded part having a base plate having a positioning hole; a detachable positioning rod having one end inserted into the positioning hole; a first fastener for fixing one end of the positioning rod inserted into the fixing hole to the inner side of the embedded part base plate; and a second fastener for fixing the other end of the positioning rod to the outer side of the insulation board; wherein, the center of the end face of the positioning rod serves as a positioning reference for determining the boundary line of the notch to be removed from the insulation board.

[0005] Furthermore, the positioning rod is threadedly connected to the first fastener and the second fastener.

[0006] Furthermore, the first fastener is a cover plate nut, with one end of the nut in a closed state.

[0007] Furthermore, the positioning rod is arranged perpendicular to the base plate, and there is one or more positioning rods.

[0008] To solve the above-mentioned technical problems, the present invention also provides a construction method for a curtain wall connector structure, comprising the following steps: installing an embedded part with a positioning rod; performing cast-in-place construction of the main structure; using the positioning rod as a positioning reference, positioning and removing the insulation board corresponding to the embedded part; retrieving the positioning rod; installing the curtain wall adapter; and performing post-insulation construction on the notch removed from the insulation board.

[0009] Furthermore, the installation of the embedded part with the positioning rod includes: installing the embedded part during the main structure reinforcement binding stage, and installing a detachable positioning rod on the base plate of the embedded part. One end of the positioning rod is inserted into the positioning hole of the base plate and fixed to the inside of the base plate facing the main structure by a first fastener, and the other end of the positioning rod extends towards the side away from the main structure; a through hole is opened at the corresponding position of the insulation board and the positioning rod, so that the positioning rod passes through the insulation board, the insulation board is laid on the outside of the main structure, and the other end of the positioning rod is fixed to the outside of the insulation board by a second fastener.

[0010] Furthermore, the positioning and chiseling includes: using the center of the end face of the positioning rod as a reference, offsetting outward by a set distance to draw a line to determine the chiseling boundary; cutting and chiseling away the insulation board within the boundary range along the drawn line to form a chiseling notch and expose the embedded part base plate.

[0011] Furthermore, the projection of the chiseled notch along the vertical direction of the embedded part base plate coincides with the base plate.

[0012] Furthermore, the recovery of the positioning rod includes removing and recovering the positioning rod and the second fastener.

[0013] Furthermore, the post-insulation construction includes: filling the gaps in the insulation board with insulation material; pasting fiber mesh around the gaps and applying adhesive mortar; and sealing the joints between the curtain wall transition piece and the insulation material with caulking material.

[0014] The curtain wall connector structure and construction method provided by this invention, compared with the prior art, through the detachable connection between the embedded part and the positioning rod, allows for precise positioning of the embedded part by the position of the positioning rod, accurately defining the range of the insulation board removal notch, and positioning and removing the insulation board corresponding to the embedded part. This avoids the removal range being too large or too small due to installation errors of the embedded part, thus improving the construction efficiency of the curtain wall connector and the curtain wall. In particular, the threaded connection between the positioning rod and the first and second fasteners increases the convenience of installation and disassembly of the positioning rod, making it recyclable and reusable. By performing post-insulation construction on the removed insulation board notch, the thermal insulation performance of the building is increased, and the thermal bridging effect is reduced.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the various embodiments of this invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this invention to facilitate a better understanding of this application.

[0019] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0020] like Figure 1-4As shown, one embodiment of the present invention relates to a curtain wall connector structure for the installation and fixing of a curtain wall, comprising: a curtain wall embedded part 30, the embedded part 30 having a base plate 31 and a connecting steel bar 32 connected to the end face of the base plate 31, the connecting steel bar 32 being used to connect with the steel bars of the main structure 10, the base plate 31 having a through positioning hole 311 for connecting a detachable positioning rod 40; one end of the detachable positioning rod 40 is inserted into the positioning hole 311, and the end of the positioning rod 40 inserted into the positioning hole 311 is fixed to the inner side of the base plate 31 of the embedded part 30 by a first fastener 41; the side of the base plate 31 facing the main structure 10 is the inner side. The other end of the positioning rod 40 extends toward the insulation board 20 and passes through the insulation board 20. The end exposed on the outside of the insulation board 20 is fastened by the second fastener 42, connecting and fixing the positioning rod 40 to the insulation board 20. The installation of the curtain wall adapter 50 and the embedded part 30 requires the insulation board 20 corresponding to the embedded part 30 to be chiseled. The positioning rod 40 is fixed relative to the bottom plate 31 of the embedded part 30, and one end of the positioning rod 40 is exposed outside the insulation board 20. With the center of the visible end face of the positioning rod 40 as the positioning reference, the boundary of the chiseling notch 21 of the insulation board 20 can be accurately positioned, improving the positioning accuracy of the range of the chiseling notch 21, improving the construction efficiency of the chiseling notch 21, and also helping to improve the quality of the insulation construction after the chiseling notch 21. Preferably, the positioning rod 40 is a metal rod with a diameter of 8mm. Both ends of the positioning rod 40 are provided with external threads. The first fastener 41 and the second fastener 42 are provided with internal threads that match the external threads. The positioning rod 40 is threadedly connected to the first fastener 41 and the second fastener 42, facilitating the disassembly and fixing of the positioning rod 40 to the base plate 31 of the embedded part 30. In one example, the first fastener 41 is a cover nut with one end closed, and the second fastener 42 is an external hexagonal nut. Through the detachable connection between the embedded part 30 and the positioning rod 40, the position of the embedded part 30 can be accurately located by visually identifying the position of the positioning rod 40, precisely defining the area of ​​the notch 21 to be removed on the insulation board 20, and improving the construction efficiency of the curtain wall connectors and the curtain wall itself. In particular, the threaded connection between the positioning rod 40 and the first fastener 41 and the second fastener 42 increases the convenience of installing and disassembling the positioning rod 40, making the positioning rod 40 recyclable and reusable.

[0021] One embodiment relates to a curtain wall connector structure, including an embedded part 30 and a positioning rod 40 detachably connected to a base plate 31 of the embedded part 30. The positioning rod 40 is perpendicular to the base plate 31, and there are one or more positioning rods 40, symmetrically arranged in the plane of the base plate 31. In one example, there are four positioning rods 40, and the base plate 31 has four positioning holes 311, the same number as the number of positioning rods 40. The base plate 31 of the embedded part 30 is rectangular, and the four positioning holes 311 are located at the four corners of the rectangular base plate 31 and are symmetrically distributed. The distance between the center of each positioning hole 311 and the edge of the adjacent base plate 31 is 15-30 mm. One end of the positioning rod 40 is inserted into the positioning hole 311 and fixed to the inner side of the base plate 31 by a first fastener 41. In use, the positioning rod 40 is detachably installed in the positioning hole 311 of the base plate 31. After the insulation board 20 has a clearance hole corresponding to the position of the positioning rod 40, the positioning rod 40 passes through the clearance hole, and the insulation board 20 is laid on the outside of the main building structure 10. The end of the positioning rod 40 away from the base plate 31 is exposed on the outside of the insulation board 20. Thus, the center of the visible end face of the positioning rod 40 exposed on the insulation board 20 is used as the positioning reference to determine the boundary of the notch 21 of the insulation board 20. In one example, the quadrilateral formed by the center line of the four positioning holes 311 is used as the reference, and the boundary of the notch 21 of the insulation board 20 is 15-30mm outward from the edge of the quadrilateral. Preferably, the projection of the notch 21 along the vertical direction of the base plate 31 coincides with the base plate 31.

[0022] like Figure 5-8 As shown, one embodiment of the present invention relates to a construction method for a curtain wall connector structure, comprising the following steps: installing an embedded part 30 with a positioning rod 40; installing the embedded part 30 during the reinforcement binding stage of the main structure 10, and installing a detachable positioning rod 40 on the base plate 31 of the embedded part 30, one end of the positioning rod 40 being inserted into the positioning hole 311 of the base plate 31 and fixed to the inner side of the base plate 31 facing the main structure 10 by a first fastener 41, the other end of the positioning rod 40 extending towards the side away from the main structure 10; opening a through clearance hole at the corresponding position of the insulation board 20 and the positioning rod 40, allowing the positioning rod 40 to pass through the clearance hole, laying the insulation board 20 on the outer side of the main structure 10, and fixing the other end of the positioning rod 40 to the outer side of the insulation board 20 by a second fastener 42. Preferably, the positioning rod 40 is a metal rod with a diameter of 8mm.

[0023] The main structure 10 is cast-in-place; after the reinforcement is tied, the embedded parts 30 and positioning rods 40 are installed, and the insulation board 20 on the outside of the main structure 10 is reinforced, concrete is poured to form an integrated wall.

[0024] Using the positioning rod 40 as a positioning reference, the insulation board 20 corresponding to the position of the embedded part 30 is positioned and removed. Using the center of the end face of the second fastener 42 as a reference, a line is drawn outwards by a set distance to determine the removal boundary. The insulation board 20 within the boundary range is cut and removed along the drawn line, forming a removal notch 21 to expose the base plate 31 of the embedded part 30. The outward offset distance is related to the position of the positioning hole 311 on the base plate 31 to ensure that the range defined by the removal boundary is not less than the area of ​​the base plate 31, and that the base plate 31 of the embedded part 30 is completely exposed to the removal notch 21. Preferably, the projection of the removal notch 21 along the vertical direction of the base plate 31 of the embedded part 30 coincides with the base plate 31.

[0025] Retrieve the positioning rod 40; after chiseling out the notch 21, unscrew the positioning rod 40 and retrieve the positioning rod 40 and the second fastener 42 for reuse; the first fastener 41 located inside the base plate 31 remains in the concrete of the main structure 10 and is not retrieved.

[0026] After the curtain wall adapter 50 is installed and the positioning rod 40 is retrieved, the curtain wall adapter 50 is installed and welded to the base plate 31 exposed in the chiseled notch 21. During construction, a fire-receiving hopper is set up to reduce safety hazards caused by welding sparks and slag.

[0027] Post-insulation construction is carried out after removing the notch 21 in the insulation board 20. The post-insulation construction includes: filling the notch 21 in the insulation board 20 with insulation material 211, wherein the insulation material 211 is a building insulation material, such as rock wool, and the notch 21 is filled with rock wool to make it dense; pasting alkali-resistant fiber mesh 212 around the notch 21 and applying adhesive mortar to seal the gap between the insulation material 211 and the insulation board 20; after filling the notch 21 with insulation material 211, the end of the curtain wall transition piece 50 away from the embedded part 30 passes through the insulation material 211 and is exposed outside the insulation material 211; the joint between the curtain wall transition piece 50 and the insulation material 211 is sealed with caulking material 213, which helps to enhance the building insulation effect and reduce the thermal bridge effect.

[0028] The curtain wall connector structure and its construction method provided by this invention, through the detachable connection between the embedded part and the positioning rod, allow for precise positioning of the embedded part and accurate definition of the area to be chiseled out of the insulation board. This enables the positioning and chiseling of the insulation board corresponding to the embedded part, avoiding excessively large or small chiseling areas due to installation errors of the embedded part, thus improving the construction efficiency of the curtain wall connector and the curtain wall itself. In particular, the threaded connection between the positioning rod and the first and second fasteners increases the convenience of installing and disassembling the positioning rod, making it recyclable and reusable. Furthermore, by performing post-insulation construction on the chiseled-out insulation board, the building's insulation performance is increased, and the thermal bridging effect is reduced.

[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be defined by the claims.
