Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an adjustable curtain wall support and its construction method. Background Technology

[0002] Glass curtain walls, as a typical building facade, are widely used in large buildings. For the ground floor glass curtain wall, its supports are embedded parts pre-installed in the basement roof slab. Steel cores are welded to these embedded parts, steel columns are fitted onto the cores, and glass support brackets are welded to the columns, forming the structural framework of the glass curtain wall. However, when the basement roof slab is large, the crisscrossing reinforcement, especially at the column heads, can cause significant construction errors during concrete pouring, resulting in substantial differences in the elevation of the embedded parts in different areas. These elevation differences affect the installation of the ground floor glass curtain wall. Currently, there are two solutions to this problem.

[0003] First, by conducting on-site measurements, the elevation of the embedded parts of the glass supports at both ends of each glass unit in the glass curtain wall is measured. The glass dimensions are calculated based on the top elevation of the first-floor glass unit and the elevation of the embedded parts, and the glass units are then cut to size according to the measured dimensions. This method can overcome the difficulty of glass installation caused by inconsistent bottom elevations of the first-floor glass curtain wall due to civil engineering errors. However, it requires on-site measurements, individual glass cutting, and numbering. During on-site installation, each glass unit is installed according to its corresponding number. This method is costly and has low efficiency during glass installation.

[0004] Secondly, the basement roof slab is ground to control the elevation error within a manageable range for the steel inserts. Then, the glass curtain wall embedded parts are re-installed using a post-installation method, and the steel inserts are welded in place. Steel columns with glass supports are then installed, thus eliminating the installation difficulties of the first-floor glass unit panels caused by errors in the basement roof slab construction. However, this method requires grinding a large area of ​​the basement roof slab, which is time-consuming and labor-intensive. Furthermore, the post-installation of embedded parts may affect the waterproofing performance of the basement roof slab.

[0005] Therefore, there is a need to provide a position-adjustable curtain wall support and its construction method, which can solve the problems of high actual measurement cost, low construction efficiency, and time-consuming and labor-intensive grinding of basement roof slabs that affects the waterproof performance of basement roof slabs in the existing technology. Summary of the Invention

[0006] The purpose of this invention is to provide a position-adjustable curtain wall support and its construction method, which can solve the problems of high actual measurement cost, low construction efficiency, and time-consuming and labor-intensive grinding of basement roof slabs that affects the waterproof performance of basement roof slabs in the prior art.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows:

[0008] An adjustable curtain wall support includes a curtain wall embedded part, a steel insert, a steel column, and an adjustable curtain wall support. The curtain wall embedded part is pre-installed on the basement roof slab and extends to the exterior of the building structure.

The steel column is sleeved on the steel insert and connected and fixed by a first connector. The adjustable curtain wall support is vertically adjustable and installed on the steel column by a second connector. The adjustable curtain wall support is connected and fixed to the steel column. The first-floor glass unit of the glass curtain wall is installed on the adjustable curtain wall support.

[0009] The curtain wall embedded parts include horizontal embedded parts, lateral embedded parts, and horizontal extension parts; the horizontal embedded parts are horizontally embedded in the basement roof slab, the lateral embedded parts are vertically embedded in the basement roof slab, and the horizontal extension parts are installed on the lateral embedded parts and located outdoors of the building structure; the steel insert is fixedly installed on the horizontal embedded parts and the horizontal extension parts.

[0010] The horizontal extension member has an L-shaped cross-section; the horizontal section of the horizontal extension member and the horizontal embedded member are located in the same horizontal plane and extend horizontally to the outdoor side; the steel insert is fixedly installed on the horizontal section of the horizontal embedded member and the horizontal extension member, so that the steel insert part is located outdoors of the building structure; the vertical section of the horizontal extension member is fitted and connected to the outer facade of the lateral embedded member.

[0011] The top surface of the horizontal embedded part is flush with the top surface of the basement roof slab, and the outer surface of the lateral embedded part is flush with the outer surface of the basement roof slab. The horizontal embedded part, the lateral embedded part, and the horizontal extension part are connected into an integrated structure.

[0012] The adjustable curtain wall support includes a back panel and a bottom panel; the back panel and the bottom panel are vertically connected to form an L-shaped integrated structure, and several vertical waist holes are formed at intervals on the back panel, so that the back panel can be vertically adjusted and installed on the steel column through the waist holes via a second connector; the bottom of the first-floor glass unit of the glass curtain wall is placed in the L-shaped space formed by the back panel and the bottom panel.

[0013] A stiffening plate is provided between the back plate and the bottom plate, and the back plate, bottom plate and stiffening plate are vertically connected to form an integral structure.

[0014] A method for constructing a position-adjustable curtain wall support includes the following steps:

[0015] Step 2: During the construction of the basement roof slab, the curtain wall embedded parts are pre-embedded simultaneously, so that part of the curtain wall embedded parts are pre-embedded in the basement roof slab and part of the curtain wall embedded parts extend to the outside of the building structure.

[0016] Step 3: Weld the steel insert to the curtain wall embedded parts so that the steel insert is located on the outside of the building structure;

[0017] Step 4: Place the steel column onto the steel insert and connect and fix the steel column and the steel insert using the first connector;

[0018] Step 5: Weld and install the second connector on the outdoor side of the steel column, and adjust the adjustable curtain wall bracket to the steel column through the second connector;

[0019] Step 6: Place a rubber pad on the base plate of the adjustable curtain wall bracket, and then install the first-floor glass unit of the glass curtain wall.

[0020] Step 2 includes the following sub-steps:

[0021] Step 101: Before pouring the basement roof slab, place the horizontal and lateral embedded parts of the curtain wall embedded parts into the basement roof slab template and fix their positions. The horizontal and lateral embedded parts are vertically connected into a whole. The top surface of the horizontal embedded parts is flush with the top surface of the basement roof slab, and the outer surface of the lateral embedded parts is flush with the outer surface of the basement roof slab.

[0022] Step 102: Pour the basement roof slab;

[0023] Step 103: After the concrete of the basement roof slab has hardened, remove the laitance from the surface of the horizontal and lateral embedded parts of the curtain wall.

[0024] Step 104: Weld the horizontally extended vertical section to the lateral embedded part so that the horizontal section of the horizontal extension part and the horizontal embedded part are in the same horizontal plane and extend horizontally to the outside of the building structure.

[0025] Step 4 includes the following sub-steps:

[0026] Step 401: Insert the back plate of the adjustable curtain wall bracket into the second connector through the waist hole, and vertically adjust the installation height of the base plate through the vertical waist hole;

[0027] Step 402: Connect the adjustable curtain wall support to the second connector to form an integrated structure;

[0028] Step 403: The back panel of the adjustable curtain wall support is connected and fixed to the steel columns on both sides.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. This invention eliminates elevation errors in the pouring of basement roof concrete by opening waist holes on the back plate of the adjustable curtain wall bracket, thereby making the installation position height of the adjustable curtain wall bracket adjustable.

[0031] 2. This invention connects the adjustable curtain wall support to the steel column by welding a second connecting part such as a screw rod onto the steel column and tightening it with a nut. This fixes the position of the adjustable curtain wall support, ensures the installation accuracy during welding, and eliminates the need for post-construction embedded parts, thus avoiding leakage problems in the basement roof slab.

[0032] 3. This invention achieves a rigid connection between the adjustable curtain wall support and the steel column by welding the two sides of the adjustable curtain wall support to the steel column, thus ensuring the stress safety of the adjustable curtain wall support.

Detailed Implementation

[0045] The adjustable curtain wall support and its construction method proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.

[0046] Please see the appendix Figure 1 and attached Figure 2 An adjustable curtain wall support includes a curtain wall embedded part 1, a steel insert 2, a steel column 3, and an adjustable curtain wall support 5. The curtain wall embedded part 1 is pre-embedded on the basement roof slab and extends to the exterior of the building structure. The steel insert 2 is fixedly installed on the curtain wall embedded part 1, so that the part of the steel insert 2 is located on the exterior of the building structure. The steel column 3 is sleeved on the steel insert 2 and connected and fixed by a first connector 4. The adjustable curtain wall support 5 is vertically adjustable and installed on the steel column 3 by a second connector 6. The adjustable curtain wall support 5 is connected and fixed to the steel column 3. The first-floor glass unit 7 of the glass curtain wall is installed on the adjustable curtain wall support 5.

[0047] By extending the embedded parts 1 of the curtain wall, the steel core 2 can be partially located outdoors of the building structure, thus adapting the installation position of the steel core 2 to the positional errors of the embedded parts caused by civil engineering errors. Depending on the civil engineering errors, the steel core 2 can also be entirely located outdoors of the building structure, which can be determined by the actual working conditions.

[0048] The steel insert 2 and the steel column 3 are the main load-bearing frame structures of the traditional glass curtain wall. Preferably, the first connector 4 can be bolts, which are used to connect and fix the steel insert 2 and the steel column 3. The installation process will not be described in detail here.

[0049] The adjustable curtain wall bracket 5 can be vertically adjusted and installed on the steel column 3, thereby meeting the installation height requirements of the first-floor glass unit 7 of the glass curtain wall and solving the problem of inconsistent bottom elevation of the first-floor glass unit 7 of the glass curtain wall due to civil engineering errors.

[0050] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 5 and attached Figure 6The curtain wall embedded part 1 includes a horizontal embedded part 101, a lateral embedded part 102, and a horizontal extension part 103; the horizontal embedded part 101 is horizontally embedded in the basement roof slab, the lateral embedded part 102 is vertically embedded in the basement roof slab, the horizontal extension part 103 is installed on the lateral embedded part 102 and located outdoors of the building structure, and the steel core 2 is fixedly installed on the horizontal embedded part 101 and the horizontal extension part 103.

[0051] The horizontal extension 103 located outside the building structure enables the horizontal extension of the curtain wall embedded part 1, thereby allowing for the horizontal adjustment of the installation position of the steel insert 2 to accommodate the positional error of the embedded part.

[0052] The horizontal embedded part 101 and the lateral embedded part 102 are components embedded inside the basement roof slab, which facilitates the installation of the horizontal extension part 103 and ensures the load-bearing capacity of the horizontal extension part 103.

[0053] Please see the appendix Figure 6 The horizontal extension member 103 has an L-shaped cross-section; the horizontal section of the horizontal extension member 103 is located in the same horizontal plane as the horizontal embedded member 101 and extends horizontally to the outdoor side; the steel insert 2 is fixedly installed on the horizontal section of the horizontal embedded member 101 and the horizontal extension member 103, so that part of the steel insert 2 is located outdoors of the building structure; the vertical section of the horizontal extension member 103 is fitted and connected to the outer facade of the lateral embedded member 102.

[0054] By extending the horizontal section of the horizontal extension member 103 to the exterior of the building structure, the horizontal area of ​​the curtain wall embedded part 1 can be increased, thereby ensuring that the welding position of the steel core 2 is closer to the exterior side than the basement roof structure, thus solving the problem of embedded part position error caused by civil engineering errors.

[0055] Please see the appendix Figure 6 The top surface of the horizontal embedded part 101 is flush with the top surface of the basement roof slab, and the outer surface of the lateral embedded part 102 is flush with the outer surface of the basement roof slab. The horizontal embedded part 101, the lateral embedded part 102 and the horizontal extension part 103 are connected into an integrated structure.

[0056] The horizontal embedded part 101, the lateral embedded part 102 and the horizontal extension part 103 can be made of steel plate and welded into a whole, thereby improving the rigidity of the curtain wall embedded part 1.

[0057] Please see the appendix Figure 3 and attached Figure 4The adjustable curtain wall support 5 includes a back plate 501 and a bottom plate 504; the back plate 501 and the bottom plate 504 are vertically connected to form an L-shaped integral structure, and a number of vertical waist holes 502 are formed on the back plate 501 at intervals, so that the back plate 501 can be vertically adjusted and installed on the steel column 3 through the waist holes 502 via the second connector 6; the bottom of the first-layer glass unit 7 of the glass curtain wall is placed in the L-shaped space formed by the back plate 501 and the bottom plate 504.

[0058] The length of the waist hole 502 can be adaptively adjusted according to the bottom elevation adjustment range of the first-floor glass unit 7 of the glass curtain wall, and the width of the waist hole 502 can be matched with the diameter of the second connector 6 to ensure that the adjustable curtain wall support 5 can only be adjusted vertically through the waist hole 502.

[0059] The back panel 501 and the bottom panel 504 are vertically connected to form an L-shaped space that can accommodate the bottom of the first-layer glass unit 7 of the glass curtain wall, ensuring the stable placement of the bottom of the first-layer glass unit 7 of the glass curtain wall.

[0060] Please see the appendix Figure 3 and attached Figure 4 A stiffening plate 503 is provided between the back plate 501 and the bottom plate 504, and the back plate 501, the bottom plate 504 and the stiffening plate 503 are vertically connected to form an integral structure.

[0061] The back plate 501, stiffening plate 503 and bottom plate 504 can be made of steel plates and welded into an integrated structure to ensure that the adjustable curtain wall support 5 can stably support the first-floor glass unit 7 of the glass curtain wall.

[0062] Preferably, the stiffening plate 503 is located in the middle of the adjustable curtain wall support 5, and two waist holes 502 are provided and symmetrically arranged on both sides of the stiffening plate 503.

[0063] A method for constructing a position-adjustable curtain wall support includes the following steps:

[0064] Please see the appendix Figure 5 and attached Figure 6 Step 1: During the construction of the basement roof slab, the curtain wall embedded part 1 is pre-embedded simultaneously, so that part of the curtain wall embedded part 1 is pre-embedded in the basement roof slab and part of the curtain wall embedded part 1 extends to the outside of the building structure.

[0065] Step 1 includes the following sub-steps:

[0066] Step 101: Before pouring the basement roof slab, place the horizontal embedded part 101 and the lateral embedded part 102 of the curtain wall embedded part 1 into the basement roof slab template and fix their positions. The horizontal embedded part 101 and the lateral embedded part 102 are vertically connected into a whole. The top surface of the horizontal embedded part 101 is flush with the top surface of the basement roof slab, and the outer surface of the lateral embedded part 102 is flush with the outer surface of the basement roof slab.

[0067] Step 102: Pour the basement roof slab.

[0068] The processes of reinforcing steel tying, formwork erection, and concrete pouring for the basement roof slab are standard construction methods in this field and will not be described in detail here. The horizontal embedded parts 101 and the lateral embedded parts 102 can be tied or welded to the reinforcing steel structure of the basement roof slab after positioning.

[0069] Step 103: After the concrete of the basement roof slab has hardened, remove the laitance from the surface of the horizontal embedded part 101 and the lateral embedded part 102 of the curtain wall embedded part 1.

[0070] Step 104: Weld the vertical section of the horizontal extension 103 to the lateral embedded part 102 so that the horizontal section of the horizontal extension 103 and the horizontal embedded part 101 are in the same horizontal plane and extend horizontally to the outside of the building structure.

[0071] Please see the appendix Figure 7 Step 2: Weld the steel core 2 to the horizontal section of the horizontal embedded part 101 and the horizontal extension part 103 of the curtain wall embedded part 1, so that the steel core 2 is located on the outside of the building structure.

[0072] Please see the appendix Figure 8 and attached Figure 9 Step 3: Place the steel column 3 onto the steel core 2, and connect and fix the steel column 3 and the steel core 2 through the first connector 4.

[0073] The steel column 3 and the steel insert 2 can be installed using conventional installation methods, which will not be elaborated here.

[0074] Please see the appendix Figure 8 To be continued Figure 10 Step 4: Weld and install the second connector 6 on the outdoor side of the steel column 3, and adjust the curtain wall support 5 to the steel column 3 in an adjustable manner through the second connector 6.

[0075] Step 4 includes the following sub-steps:

[0076] Step 401: Insert the back plate 501 of the adjustable curtain wall support 5 into the second connector 6 through the waist hole 502, and vertically adjust the installation height of the base plate 504 through the vertical waist hole 502.

[0077] Preferably, the second connector 6 can be a screw. The height of the base plate 504 can be adjusted according to the actual measured pouring elevation of the basement roof slab to meet the installation height requirements of the first-floor glass unit 7 of the glass curtain wall and ensure the installation space for the first-floor glass unit 7 of the glass curtain wall.

[0078] Step 402: Tighten the screw, i.e. the nut of the second connector 6, to connect the adjustable curtain wall support 5 and the second connector 6 into an integrated structure.

[0079] Step 403: Weld the adjustable curtain wall support 5 to the steel column 3 on both sides of the back plate 501 of the adjustable curtain wall support 5 to ensure the installation firmness and use safety of the adjustable curtain wall support 5.

[0080] Please see the appendix Figure 11 Step 5: Place a rubber pad on the base plate 504 of the adjustable curtain wall support 5, and then install the first glass unit 7 of the glass curtain wall.

[0081] The glass unit 7 on the first floor of the glass curtain wall can be installed using traditional installation techniques, and the installation process will not be described in detail here.

[0082] This invention effectively eliminates the problem of insufficient installation space for the first-floor glass units of the glass curtain wall caused by the pouring error of the basement roof concrete elevation by setting adjustable curtain wall brackets. This solves the problem of increased construction costs and reduced construction efficiency caused by actual measurement or grinding of the basement roof to eliminate errors, and ensures the installation quality of the first-floor glass units of the glass curtain wall.
