DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 A new curtain wall support in the utility model includes a structural beam with a cantilevered ear formed on the outside, which is connected to the structure by a plurality of screw connection pairs. During use, a pre-tightening force can be applied by using the screw connection pairs. The pre-tightening force causes friction between the components to achieve the purpose of fixation. Under normal use conditions of the glass curtain wall, when the material needs to be replaced due to maintenance, or reinforcement is required due to load changes, the support can be quickly replaced, such as replacing screws, support plates and other components.

[0028] The curtain wall support in this embodiment specifically includes a first connection pair 1, which passes through the support surface 31 formed by the cantilever 2 and the base 3, so that the cantilever 2 and the base 3 are integrally connected; when connected, it also includes an angle code group 4 located on the outside of the cantilever 2, and the angle code group 4 is connected to the base 3 through a second connection pair 5, thereby ensuring the connection near the cantilever.

[0029] Of course, it also includes a column 7 located outside the structural beam 6 and the cantilever 2. The cantilever 2 is specifically formed by the structural beam 6 extending outward, and the column 7 is formed by splicing a plurality of column units 71.

[0030] In order to realize the connection of the column units 71, at this time, the angle code group 4 forms an assembly cavity, and then the adjacent column units are assembled in the assembly cavity. Specifically, among the plurality of column units 71, the adjacent parts of the adjacent column units 71 are located in the assembly cavity formed by the angle code group 4, and in the same assembly cavity, the third connection pair 8 passing through the column unit 71 is respectively crossed at the first height and the second height. At this time, the third connection pair 8 connects different column units to the angle code group respectively, and at this time, since the connection pairs of two heights are set on the same angle code group, the two column units are connected through the same angle code group 4 in disguised form.

[0031] Refer to the attached Figure 2 As shown, the base 3 in this embodiment includes a support surface 31 and a connection surface 32 formed by the side of the support surface 31 extending downward, and the connection surface 32 is arranged close to the angle code group 4. The two surfaces in different directions are used to complete the assembly in different directions respectively, and at this time, the support surface 31 can also support the pick ear synchronously, and complete the entire assembly in combination with the first connection pair, achieving multiple goals at one stroke. Compared with a separate assembly part, the setting of the support surface enables the pick ear to have a certain supporting force and increase the strength.

[0032] In order to further increase the strength, a plurality of stiffening ribs 33 are arranged below the support surface 31 and staggered with the first connection pair 1, and the stiffening ribs 33 are located on the back of the connection surface 32. At this time, the staggered arrangement of the stiffening ribs enables the side of the first connection pair to have a certain supporting force, and the stiffening ribs located on the back of the connection surface also provide a certain supporting force to the connection surface.

[0033] As shown in the accompanying drawings, in this embodiment, the base actually forms an L-shaped structure, and then a stiffening rib 33 is set in the semi-enclosed structure formed by the L-shape. The stiffening rib is a right-angle plate, and the right-angle sides of the right-angle plate are parallel to the connection surface and the support surface respectively. The hypotenuse of the right-angle plate is set close to the structural beam, and it realizes support in multiple directions. Since the first connection pair passes through the ear 2, it is necessary to fully consider the strength near the structural beam. Therefore, in this embodiment, at least one stiffening rib 33 is set on both sides of each first connection pair 1 to protect the first connection pair 1.

[0034] Refer to the attached Figure 1 and 4 As shown, the angle code group 4 in this embodiment includes a first angle code 41 and a second angle code 42 symmetrically arranged along both sides of the column unit 71, and the first angle code 41 and the second angle code 42 are connected by the third connection pair 8. At this time, the assembly cavity is formed between the first angle code and the second angle code, so that the column unit can be clamped and fixed to ensure the connection of multiple column units. Specifically, the number of angle code groups is less than the number of column units, that is, if two column units constitute a column, then one angle code group is required, if three column units constitute a column, then two angle code groups are required, and so on.

[0035] In order to facilitate processing and production, the first angle code 41 and the second angle code structure 42 are the same, both of which are L-shaped structures, the long side of the L-shaped structure forms the assembly cavity, and the short side of the L-shaped structure is arranged close to the base. At this time, the long side can form a larger assembly cavity due to its longer length, and the short side fits with the base for connection and assembly.

[0036] In order to avoid assembly, the short sides of the two L-shaped structures are arranged in opposite directions and connected to the end of the base 3 through the second connection pair 5. At this time, the reverse arrangement makes it possible to have no gap between the base and the column, which is convenient for fitting. At the same time, the reverse arrangement makes the short sides on the outside, so that the connection can also form a protective reinforcement on both sides of the assembly cavity.

[0037] In this embodiment, adjacent column units 71 are symmetrically arranged at the upper and lower sides of the angle code group 4, and adjacent column units 71 form a column gap in the assembly cavity formed by the angle code group 4. In this embodiment, the column gap is increased to achieve the ideal state of hinge connection under structural requirements.

[0038] In this embodiment, specifically, the replaceable all-bolt fixed support is composed of a bolt connection pair, an unequal angle steel base group (i.e., base 3) and an angle code group 4. The upper and lower columns of the curtain wall are connected to the angle code group 4 using a stainless steel bolt connection pair (i.e., the third connection pair); the angle code group 4 is connected to the unequal angle steel base using a common bolt connection pair (i.e., the second connection pair); the unequal angle steel base group is connected to the concrete ear 2 using a common bolt connection pair (i.e., the first connection symbol).

[0039] When using this utility model, its applicable scope is as follows:

[0040] The curtain wall support composed of replaceable all-bolt fixed supports can be used not only for glass curtain walls, but also for other curtain walls such as stone curtain walls and metal curtain walls. The basic working conditions for the bearing capacity design of the support are: design intensity 8 degrees (0.15g), basic wind pressure once in 50 years 0.45KNm 2 , The curtain wall wind load calculation height is 100m and the shape coefficient is considered according to the side span wind zone. The curtain wall self-weight load is calculated as follows: the profile is 6063T6 thermal insulation aluminum alloy, and the glass is 5+12+5+12+5mm three-glass two-cavity. When the above conditions are exceeded during actual use, the bolt material grade, quantity, diameter, steel plate thickness, angle code spacing and bolt spacing, etc. need to be adjusted according to the calculation conditions.

[0041] According to different environments or requirements, the lugs can be set at the bottom or middle of the beam, and the unequal angle steel base can be placed above or below the concrete lugs. When the main structure is a steel structure, the replaceable full-bolt fixed support can also be used directly.

[0042] The commonly used materials and sizes of curtain wall supports in this embodiment are introduced as follows:

[0043] Three sets of connection pairs (i.e. bolt connection pairs): 3 12mm diameter 5.6 grade (A) ordinary bolt connection pairs, 6 6mm diameter 5.6 grade (A) ordinary bolt connection pairs, 4 6mm diameter A2 grade stainless steel bolt connection pairs, matching Q235B nuts and washers.

[0044] Base 3 composed of unequal angle steel base group: Q235B grade hot-rolled L125×80×7mm unequal angle steel is used, and the length of a single piece is 180mm, which is formed by cutting. Three oblong holes are opened on the short side of the angle steel, and connected to the concrete ear through 3M12 bolts; 6 oblong holes are opened symmetrically on the long side, and the angle code is fixed through 6M6 bolts. Each base is equipped with 4 steel plate stiffening ribs, the stiffening ribs are 4mm thick, and the height of the stiffening ribs should not be less than 80mm. The base can also be made of 7mm thick steel plate cold bending.

[0045] Angle code group 4: Use Q235B grade 4mm thick hot-rolled steel plate to be cold-bent into an L shape. The length of each angle code should not be less than 200mm, the width of the short leg of the angle code should not be less than 50mm, and the width of the long leg should not be less than the cross-sectional height of the aluminum alloy column. Four oblong holes are symmetrically opened on the long leg side, and the aluminum alloy column is fixed by 4M6 bolts. In order to allow the aluminum alloy column to form an assumed hinge support here and meet the requirements of the internal force and displacement of the support, the arrangement of the bolt position should ensure that the spacing between the upper and lower aluminum alloy columns is not less than 10mm. The angle code can also be replaced by unequal angle steel of the same thickness.

[0046] Concrete cantilever lug: The cantilever lug of reinforced concrete is 150mm long and the thickness of the cantilever lug should not be less than 150mm. The cantilever lug is equipped with φ10@150mm stress-bearing steel bars. The cantilevered end of the stress-bearing steel bars is bent downward and folded into the beam, and 2φ8 structural steel bars are set along the height direction at the cantilevered end. The strength of the cantilever lug concrete should not be lower than C30 and should be constructed together with the main structure.

[0047] The utility model has the following characteristics:

[0048] (1) The designed replaceable support completely abandons the rear anchoring construction and on-site welding operations. The construction is quick and easy, which can reduce the curtain wall construction period. At the same time, the structure is safe and effective, which can effectively avoid common quality problems.

[0049] (2) The designed replaceable support adopts a full bolt installation method, so the various components of the support are replaceable, which is suitable for subsequent maintenance and renovation of the curtain wall. The support can be installed not only on concrete structures, but also on steel beams and floor decking ears.

[0050] See attached Figure 5 As shown, when the curtain wall support in the utility model is used, the construction process is as follows:

[0051] (1) Overall construction process

[0052] The installation process of the support mainly involves preliminary cleaning, laying out and drilling, and component installation and adjustment. The specific process flow chart is shown below.

[0053] (2) Specific construction methods

[0054] 1) Cleaning and positioning

[0055] Process and weld the unequal angle steel base and angle bracket according to the large-scale drawing. The processed plates, holes, cuts, welding grooves, etc. must be deburred and milled to meet the acceptance standards. The steel plate surface at the bolt contact point should be sandblasted according to the design requirements to increase the friction coefficient. The processed steel plates and bolt connection pairs are sprayed with anti-corrosion and anti-rust paint and are ready for use after acceptance by all parties.

[0056] According to the glass curtain wall design drawing, the horizontal and vertical axes of the support points are set out and marked on the concrete ears. The concrete surface where the support needs to be installed is polished and the floating slurry is removed. According to the axis, the short limb surface size of the angle steel base is popped out on the ears with ink lines, and then the three M12 bolt points are marked. Then the points are inspected and accepted. After the acceptance is qualified, a through hole with a diameter of 14mm is drilled from top to bottom. The center spacing between the holes is about 70mm, and the hole margin should not be less than 50mm from the ear edge. After the drilling is completed, the dust on the ear surface can be cleaned. After the hole is completed, the hole quality inspection should be carried out.

[0057] 2) Installation of base and additional weight

[0058] Align the screw holes of the unequal angle steel base with the holes on the concrete ear, let the M12 screw pass through the hole and then tighten the nut, adjust the position of the angle steel base so that the center line of the steel plate support is located at the center line of the glass curtain wall column, and then adjust the horizontality and verticality to meet the construction acceptance standards. After acceptance, the angle steel base is initially fixed. The short limb surface of the angle steel is required to be tightly attached to the concrete surface. When the flatness error of the concrete ear surface is large and the angle steel base cannot be tightly attached to it, a 2.0mm thick polytetrafluoroethylene plate with the same length and width as the angle steel base can be used as a flexible bonding pad. When the short limb surface partly exceeds the edge of the ear due to errors, the excess distance should not be greater than 20mm, otherwise local reinforcement measures should be taken. Use 6M6 bolts to connect the deputy angle code and the steel plate support to initially fix it, adjust the position of the angle code to meet the requirements, and the initial fixation of the angle code on the angle steel base is completed.

[0059] 3) Column installation and subsequent processes

[0060] When installing the aluminum alloy columns of the curtain wall, use 4M6 stainless steel bolts to connect the columns and angle brackets, and use 2mm thick isolation gaskets to isolate, adjust and fix the stainless steel and aluminum alloy materials. When the columns and beams need to be adjusted due to construction errors, they can be adjusted through the oblong holes. Finally, the axis, elevation, verticality and flatness of the columns and beams are inspected and accepted as a whole. Only after passing the acceptance can the next construction process be carried out.

[0061] With the utility model, the entire construction period is shortened, and since the chemical bolt installation process is omitted, about 15% of the construction period can be saved.

[0062] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
