Description

Technical Field

[0001] This invention belongs to the field of curtain wall installation technology, specifically to a prefabricated building curtain wall support structure. Background Technology

[0002] Curtain walls, as a type of building envelope, serve both a structural and decorative function. They consist of a supporting structure and glass panels, and do not bear the load of the main structure. Because they are hung like a curtain, they are also called curtain walls. As a new type of building envelope, curtain walls weigh only 1 / 10 of traditional brick walls, and aluminum curtain walls weigh as little as 1 / 20. Therefore, they effectively reduce the load on the main building envelope and are characterized by their light weight, high rigidity, and excellent decorative effect, making them widely used in modern architectural design.

[0003] In practical engineering, the main structure and the curtain wall support structure are often connected via adapters, but the traditional construction process for adapters is quite complex. Typically, the mounting plate is connected to the main structure using anchor bolts, the adapter is installed on the plate, and then the curtain wall columns are connected to the adapter with bolts. The beams and columns are usually fixed using connectors or angle brackets, and then the joints are welded. Because the adapters and support plates are perpendicular to the wall structure, they cannot effectively transfer the external loads on the curtain wall frame to the wall structure. Furthermore, most joints between components are welded; if the welding quality is poor, the load-bearing capacity of the joints between the connectors, beams, and columns will be too low, leading to shear failure. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a prefabricated building curtain wall support structure. The connecting components are installed and fixed on the wall, and the support plates on the connecting components are attached to the wall, which can effectively transfer the load to the wall. The support plates are connected to the adapter components through the vertical plates, thereby supporting the installation components and the keel. The setting of the vertical plates and the support of the brackets for the vertical plates can increase the shear and bending resistance of the support structure, thereby improving the load-bearing capacity of the support plates.

[0005] The technical solution adopted in this invention is as follows:

[0006] A prefabricated building curtain wall support structure includes a connecting component installed on the wall.

[0010] Preferably, the base has a receiving groove on its side wall for placing the keel, and the side wall of the receiving groove is provided with a third bolt that passes through the receiving groove and the keel.

[0011] Preferably, the receiving groove is provided with a card plate perpendicular to the bottom of the receiving groove, and the keel is provided with a slot that engages with the card plate.

[0012] Preferably, a fourth bolt is vertically and movably inserted through the support plate, and the support plate is detachably connected to the support plate through the fourth bolt.

[0013] Preferably, the support plate is horizontally provided with a support embedded plate installed in the wall.

[0014] Preferably, the support plate is provided with a fifth bolt that penetrates the support plate, and a metal washer is fitted on the fifth bolt.

[0015] Preferably, the support plate is provided with a sixth bolt that penetrates the support plate perpendicular to the wall.

[0028] The following is combined with Figures 1-5 The present invention will be described in detail below.

[0029] Example

[0030] A prefabricated building curtain wall support structure includes a connecting component 2 installed on a wall 1. The connecting component 2 includes a support plate 204 that is attached to the wall 1. A vertical plate 209 and a support plate 205 that abuts against the bottom of the vertical plate 209 are vertically installed on the support plate 204. A transition component 3 is connected to the vertical plate 209. An installation component 4 is provided on the transition component 3. A keel 5 is installed on the installation component 4.

[0031] like Figure 1 and 2 As shown, the weight of the keel 5 and the curtain wall is transferred to the vertical plate 209 through the installation component 4 and the adapter component 3. The vertical plate 209 then transfers the load to the wall 1 through the support plate 204, ensuring the support strength of the support structure. At the same time, since the vertical plate 209 is set vertically, its bending resistance is enhanced. In addition, the shear resistance of the vertical plate 209 is improved by the support plate 205.

[0032] The adapter assembly 3 includes two vertically arranged clamping plates 303 that form a slot 302. One end of the two clamping plates 303 is fixedly connected to a connector 301 that is connected to the mounting assembly 4. Several first bolts 304 are provided on the clamping plates 303 that penetrate the clamping plates 303 and the upright plate 209.

[0033] like Figure 2 and 3 As shown, the slot 302 between the two clamping plates 303 cooperates with the upright plate 209, and is then fixed by the first bolt 304 passing through the clamping plate 303 and the upright plate 209, which is convenient for both installation and disassembly.

[0034] The side wall of the support plate 204 is provided with a second bolt 208 that passes laterally through the support plate 204, the clamping plate 303, and the upright plate 209. The support plate 204 has a "door" shaped structure to increase its strength. Since it is inconvenient to install the first bolt 304 at the end of the clamping plate 303 near the support plate 204, one or more sets of second bolts 208 are provided on the outside of the support plate 204 to pass laterally through the support plate 204, the clamping plate 303, and the upright plate 209. This can transfer the force on the clamping plate 303 to the support plate 204, increasing the connection strength of the adapter assembly 3.

[0035] like Figure 4 As shown, the mounting component 4 includes a base 401, on which a threaded hole 405 is provided for threaded connection with the connector 301. The threaded connection between the base 401 and the connector 301 facilitates subsequent disassembly. To ensure the base 401 is screwed into the appropriate position, a baffle 305 can be provided on the connector 301, or the threaded hole 405 can be designed as a non-through hole.

[0036] The base 401 has a receiving groove 404 on its side wall for placing the keel 5. A third bolt 403 is provided on the side wall of the receiving groove 404, which passes through the receiving groove 404 and the keel 5. The end of the keel 5 is inserted into the receiving groove 404 and fixed by the third bolt 403, which facilitates the installation and removal of the keel 5.

[0037] A retaining plate 402 perpendicular to the bottom of the receiving groove 404 is provided in the receiving groove 404, and a slot 6 is provided on the keel 5 to engage with the retaining plate 402. The retaining plate 402 and the slot 6 cooperate to improve the engagement stability of the keel 5, thereby ensuring the stability of the keel 5 in use.

[0038] When installing keel 5 and mounting component 4, deviations must be strictly controlled. The elevation error of keel 5 during installation must be less than or equal to 3mm, the front-to-back deviation of the axis must be less than or equal to 2mm, and the left-to-right deviation of the axis must be less than or equal to 3mm. Simultaneously, the elevation deviation between two adjacent keels 5 must be no greater than 3mm, the maximum elevation deviation of keels 5 in the same layer must be no greater than 5mm, and the distance deviation between two adjacent keels 5 must be no greater than 2mm. Furthermore, flat washers must be added at bolt connections to ensure a secure and reliable connection. Relevant load-bearing tests must be conducted before use.

[0039] A fourth bolt 206 is vertically and movably inserted through the support plate 204. The tray 205 is detachably connected to the support plate 204 via the fourth bolt 206, making it convenient to replace the tray 205 if it is damaged.

[0040] A support plate 201 is horizontally mounted on the support plate 204 and installed inside the wall 1. The support plate 201 is used to install the connecting assembly 2 on the wall 1. The support plate 201 is made of 160mm*160mm aluminum alloy square plate. The support plate 201 and the support plate 204 are fixed by welding, and the contact points are fully welded.

[0041] A fifth bolt 203 is provided on the support plate 201, penetrating the support plate 201. The fifth bolt 203 fixes the support plate 201 inside the wall 1, thereby fixing the entire connecting assembly 2 to the wall 1. A metal washer 202 is fitted on the fifth bolt 203. The metal washer 202 can effectively prevent the fifth bolt 203 from loosening. There are two metal washers 202, each with a certain curvature, and the two metal washers 202 are positioned opposite each other. The tightness of the fifth bolt 203 is judged by the degree of flattening between the two metal washers 202. Before installing the connecting assembly 2, a certain space needs to be processed in the wall 1 to facilitate the placement of the support plate 201 and the installation of the fifth bolt 203.

[0042] Before installing the support plate 201 and support plate 204, the concrete surface of the structure must be inspected. If unevenness is found, it can be remedied by chiseling or using micro-expansion cement. The contact area between the connecting component 2 and the concrete surface of the wall 1 should be no less than 70%. After the installation of the connecting component 2 is completed, its deviation must be checked. The deviation in all directions must not exceed ±45mm. Any deviations exceeding this limit must be welded using steel plates of the same thickness as the support components. When the weld height is greater than or equal to 7mm, the weld must be a perimeter weld, and the other end must be connected using an M12*160 building anchor bolt.

[0043] A sixth bolt 207 is installed on the support plate 204, perpendicular to the wall 1 and penetrating through the support plate 204. The sixth bolt 207 fixes the support plate 204 to the wall 1, further increasing the connection stability of the connecting component 2. The sixth bolt 207 is a chemical anchor, and the chemical anchor is M12*160mm. The distance from the center of the anchor to the edge of the concrete structure should be no less than 85mm, and the distance between two anchors should be greater than 120mm. Before processing the holes suitable for the chemical anchors, measurement and layout work is required to ensure the accuracy of the hole position. The required drilling position for the anchor or bolt can be marked with an ink line, and drilling work is carried out according to the marked cross lines. To ensure the drilling depth, the drilling depth dimension should be marked on the drill bit in advance, and tape should be wrapped around the impact drill bit before drilling. Before installing the chemical anchor, the dust in the hole should be cleaned, and the chemical agent should be placed at the edge of the hole before installing the anchor. After the screw is driven in, it should be quickly stirred until a small amount of mixture is exposed at the hole opening. After the anchor bolt installation is completed, the next step of construction cannot be carried out immediately. It is necessary to wait for the chemical reagents to react and solidify to reach sufficient strength before the next step of construction can begin.

[0044] The supporting structure of this application pre-positions and installs the supporting components onto the concrete wall structure during factory production. During on-site construction, only the various installation structures need to be installed sequentially to form connection nodes before the curtain wall keel is connected and installed. This not only greatly improves the construction speed but also ensures convenient disassembly when repairing or replacing local components later, thereby extending the service life of the supporting structure. Furthermore, the supporting structure of this application adopts a fully assembled design, making the construction process green, environmentally friendly, and cost-effective: most welding procedures are completed in the factory, and minimal welding operations are required during construction assembly, reducing noise pollution. On-site assembly mainly involves bolt insertion, simplifying the operation.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
