DETAILED DESCRIPTION

[0030] The following non-limiting examples are provided to illustrate the present application.

[0031] Example 1

[0032] refer to Figure 1 and Figure 2 As shown, a curtain wall force transmission system includes a building body 1, a reserved window opening 2, a curtain wall embedded plate 3, a connecting rod 4, a curtain wall keel 5, a curtain wall panel 6, a window opening sub-frame 7, a window main frame 8, mortar 9, an adjustable support 10, a force transmission rod 11 and a glass 12.

[0033] The main building 1 is a wall or beam of a reinforced concrete structure, and the entire curtain wall is constructed on the main building 1. A number of reserved window openings 2 are formed on the main building 1, and the reserved window openings 2 are used for the subsequent placement of curtain wall glass. Curtain wall keels 5 are fixed on the main building 1, and a number of curtain wall keels 5 are arranged horizontally. The curtain wall keels 5 are square tubes or rectangular tubes. The loads of other curtain wall structures are gathered on the curtain wall keels 5, and then act on the main building 1 through the curtain wall keels 5.

[0034] A plurality of embedded curtain wall panels 3 are provided on the building body 1. The embedded curtain wall panels 3 are made of steel plates and are fixed to the building body 1 by expansion bolts. The embedded curtain wall panels 3 are welded to the inner ends of the connecting rods 4. The outer ends of the connecting rods 4 are welded to the curtain wall keels 5. The connecting rods 4 also adopt square tubes or rectangular tubes to realize the connection transition between the embedded curtain wall panels 3 and the curtain wall keels 5.

[0035] A plurality of curtain wall embedded panels 3 fix a curtain wall keel 5, so as to realize reliable fixation of the curtain wall keel 5 on the building main body 1. A curtain wall panel 6 is fixed on the curtain wall keel 5, and the curtain wall panel 6 is located on the outside for decorative protection. A plurality of curtain wall panels 6 are directly arranged horizontally on the keel by screws.

[0036] A window hole sub-frame 7 is fixed in the reserved window hole 2, and the window hole sub-frame 7 is preferably made of metal. The reserved window hole 2 and the window hole sub-frame 7 are both rectangular, but the size of the window hole sub-frame 7 is slightly smaller than the reserved window hole 2. Mortar 9 is filled between the reserved window hole 2 and the window hole sub-frame 7 to seal the gap between the two to achieve waterproof and windproof.

[0037] An adjustable support member 10 is provided between the bottom of the window hole sub-frame 7 and the reserved window hole 2. The window hole sub-frame 7 can be supported by the adjustable support member 10. At the same time, the adjustable support member 10 can also adjust the support height to adjust the flatness of the window hole sub-frame 7 to ensure the construction quality of the subsequent curtain wall glass.

[0038] The window hole auxiliary frame 7 transmits force to the concrete building main structure through the adjustable support member 10 and the filling mortar. Because it is difficult to ensure the flatness of the structural surface during concrete pouring, the adjustable support member 10 is placed during concrete pouring to support the weight of the auxiliary frame and the glass upwards.

[0039] The adjustable support member 10 includes a pre-embedded threaded sleeve 101 and a supporting threaded rod 102. The pre-embedded threaded sleeve 101 is pre-embedded inside the building body 1, and the pre-embedded threaded sleeve 101 is threadedly matched with the lower end of the supporting threaded rod 102, and the upper end of the supporting threaded rod 102 supports the window hole sub-frame 7, and the height adjustment can be achieved by rotating the supporting threaded rod 102.

[0040] A plurality of force transmission rods 11 are connected between the curtain wall keel 5 and the window hole sub-frame 7. The force transmission rods 11 transmit the load of the curtain wall glass to the curtain wall keel 5, avoiding the safety hazard of the curtain wall glass not being provided with a connection structure, and also avoiding the complicated process of adding an additional connection structure. The plurality of force transmission rods 11 are evenly arranged on the window hole sub-frame 7 to ensure uniform load action.

[0041] The main weight of the building curtain wall comes from the weight of the curtain wall panels and the weight of the glass. This weight is mainly transferred to the curtain wall keel and the window opening sub-frame. The curtain wall keel transfers the force to the structural wall or beam surface through the curtain wall embedded plate. The curtain wall keel and the sub-frame are welded to form a whole using force transfer rods. The keel and the sub-frame jointly transfer the force to the main structure through the embedded plate and supporting components.

[0042] The force transmission rod 11 includes a force transmission horizontal rod 111, a force transmission vertical rod 112 and a force transmission diagonal rod 113, all of which are square tubes or rectangular tubes. The inner end of the force transmission horizontal rod 111 is welded to the window opening sub-frame 7, the outer end of the force transmission horizontal rod 111 is connected to the upper end of the force transmission vertical rod 112, and the lower end of the force transmission vertical rod 112 is connected to the curtain wall keel 5, so as to realize load transmission while satisfying the right-angle structure at the window opening. A force transmission diagonal rod 113 is welded between the force transmission horizontal rod 111 and the force transmission vertical rod 112 to strengthen the structures of both.

[0043] A main window frame 8 is arranged inside the window hole sub-frame 7. The main window frame 8 is also rectangular. The outer contour of the main window frame 8 just matches the inner contour of the window hole sub-frame 7. The main window frame 8 is fixed to the window hole sub-frame 7 by screws. Glass 12 is arranged inside the main window frame 8. Glue is applied between the main window frame 8 and the glass 12 to seal.

[0044] This force transmission volume can strengthen the force conduction between the building curtain wall and the main structure, effectively transfer the force on the curtain wall glass, curtain wall keel and curtain wall panel to the main structure of the building, and improve the structural safety of the building curtain wall.

[0045] Example 2

[0046] A construction method of a curtain wall force transmission system is based on a building main body 1 that has been cast and completed to obtain a curtain wall force transmission system of Example 1. When the building main body 1 is cast, a pre-embedded threaded sleeve 101 with an inner thread is pre-embedded in the concrete component near the window in advance to facilitate the subsequent installation of a supporting threaded rod 102 on the sleeve.

[0047] The construction method comprises the following steps: the first step is to fix several layers of horizontally arranged curtain wall keels 5 on the building body 1, and the loads of other curtain wall structures are gathered on the curtain wall keels 5, and then act on the building body 1 through the curtain wall keels 5.

[0048] Several layers of embedded curtain wall panels 3 are installed on the main building 1. Each layer of embedded curtain wall panels 3 includes several horizontally arranged panels. The embedded curtain wall panels 3 are fixed to the main building 1 by expansion bolts. Then the inner ends of the connecting rods 4 are welded to the embedded curtain wall panels 3, and the outer ends of the connecting rods 4 are welded to the curtain wall keels 5, so that the curtain wall keels 5 are fixed to the main building 1 in a horizontal state.

[0049] The second step is to place an adjustable support member 10 at the bottom of the reserved window opening 2 of the building body 1. The adjustable support member 10 can support the window opening sub-frame 7, and the adjustable support member 10 can also adjust the support height to adjust the flatness of the window opening sub-frame 7 to ensure the construction quality of the subsequent curtain wall glass.

[0050] Since a plurality of embedded threaded sleeves 101 of the adjustable support members 10 are arranged in advance at the bottom of the reserved window openings 2 of the building main body 1 , in the second step, the support threaded rods 102 are screwed into the embedded threaded sleeves 101 .

[0051] The third step is to temporarily position and install the window hole sub-frame 7 in the reserved window hole 2. The sub-frame is fixed to the concrete structure beside the window through a fixing piece, and an adjustable support member 10 is provided below the sub-frame.

[0052] The fourth step is to operate the adjustable support member 10 to support the adjustable support member 10 between the bottom of the window hole sub-frame 7 and the reserved window hole 2. Through the threaded cooperation between the embedded threaded sleeve 101 and the support threaded rod 102, the support threaded rod 102 is rotated to tighten the window hole sub-frame 7, so that the adjustable support member 10 is completely fitted with the metal sub-frame, and can effectively support the sub-frame.

[0053] In the fifth step, a force transmission rod 11 is connected between the curtain wall keel 5 and the window opening sub-frame 7, and the force transmission rod 11 transmits the load of the curtain wall glass to the curtain wall keel 5.

[0054] The force transmission rod 11 includes a force transmission horizontal rod 111, a force transmission vertical rod 112 and a force transmission diagonal rod 113, all of which are square tubes or rectangular tubes. The outer end of the force transmission horizontal rod 111 is first welded to the upper end of the force transmission vertical rod 112 to form an L-shaped rectangular tube structure, and the force transmission diagonal rod 113 is welded between the force transmission horizontal rod 111 and the force transmission vertical rod 112 to strengthen the structure. Then, the inner end of the force transmission horizontal rod 111 is welded to the window hole sub-frame 7, and the lower end of the force transmission vertical rod 112 is welded to the curtain wall keel 5.

[0055] In the sixth step, a plurality of curtain wall panels 6 are installed on the curtain wall keels 5 , and the curtain wall panels 6 are fixed on the curtain wall keels 5 by screws.

[0056] The outer side of the window hole sub-frame 7 and the reserved window hole 2 are filled and blocked, and mortar 9 is filled between the outer side of the window hole sub-frame 7 and the reserved window hole 2, and the outer surface of the mortar 9 is flush with the outer surface of the window hole sub-frame 7.

[0057] The window body is installed inside the window hole sub-frame 7, and the window body includes a window main frame 8 and glass 12. The window main frame 8 is installed inside the window hole sub-frame 7, and the window main frame 8 is fixed on the window hole sub-frame 7 by screws. The glass 12 is placed in the window main frame 8, and the window main frame 8 and the glass 12 are sealed with glue.
