In this embodiment, the cavities 3 are distributed in the outer frame indoor layer 11, the outer frame outdoor layer 12, the window frame indoor layer 211, and the window frame outdoor layer 212. The outer frame indoor layer 11 and the outer frame outdoor layer 12 are formed by splicing an outer frame cross beam and an outer frame longitudinal beam respectively, the window frame indoor layer 211 and the window frame outdoor layer 212 are formed by splicing a window frame cross beam and a window frame longitudinal beam respectively, and hollow cavities with two ends penetrating through are arranged on the inner sides of the outer frame cross beam, the outer frame longitudinal beam, the window frame cross beam and the window frame longitudinal beam, namely the cavity 3. The transversely arranged reinforcing brackets 31 are distributed along the cavities 3 of the outer frame cross beam and the window frame cross beam, and the longitudinally arranged reinforcing brackets 31 are distributed along the cavities 3 of the outer frame longitudinal beam and the window frame longitudinal beam.

The reinforcing bracket and the corner brace are made of steel materials.

Preferably, the two ends of the corner brace 5 are respectively provided with a notch 51 for the insertion of the tail end of the reinforcing bracket, and the top wall and the bottom wall of the notch 51 are symmetrically provided with screw holes 52. Strengthen support 31, angle sign indicating number 5 carries out fixed connection through screw or pin and window frame body 21 or frame 1 (the lateral wall of cavity 3), it is whole to connect into with outside frame (aluminum alloy material) the inside skeleton (steel) that will strengthen the leg joint and form, improve the holistic fire resistance of window body, and simultaneously, strengthen structure 41 with angle sign indicating number 5 and strengthen support 31 integral connection through outside bight is fire-resistant, can strengthen the fire resistance of frame system, ensure that the fire-resistant integrality of fire-resistant unit window satisfies the national standard requirement.

The second connection mode is as follows: as shown in fig. 6-7, the end of the horizontally disposed reinforcing bracket 31 is fixedly connected (by screws or pins) to the longitudinally disposed reinforcing bracket indirectly through a reinforcing connector 37, and the reinforcing connector 37 and the horizontally disposed reinforcing bracket 31 are located in the same beam (window frame beam or outer frame beam) cavity 3. The transverse reinforcing brackets 31 and the transverse beams are indirectly in threaded connection or pin connection with the longitudinal beams and the longitudinal reinforcing connecting pieces 37 through connecting steel plates 38, and the reinforcing connecting pieces 37 are in threaded connection or pin connection with the longitudinally arranged reinforcing brackets, so that the transverse structure and the longitudinal structure are fixedly connected.

The right end of the reinforcing connecting piece 37 is provided with an inserting protrusion 376, and the inserting protrusion 376 is longitudinally inserted into a clamping groove 377 in the longitudinal beam.

In addition, glue can be injected into the second screw hole 375 and enters a gap of the first screw hole 373 and a gap at the insertion position of the reinforcing connecting piece 37 and the longitudinal beam, so that various connection modes of screw connection, insertion connection and adhesion between the reinforcing connecting piece 37 and the longitudinal beam and the internal structure of the longitudinal beam are realized, and the connection strength and the stability between the transverse structure and the longitudinal structure in the reinforced unit window body are achieved.

A connecting steel plate 38 is provided outside the cross member where the reinforcing links 37 are located, and a projection of the connecting steel plate 38 extends from one side of the reinforcing links 37 to the end of the unit window.

Wherein, the fireproof reinforced structure 43 of joining type has strengthened the fire-resistant stability of corner structure junction for the high temperature resistant steel sheet of stack setting and the high temperature resistant fire prevention silver of ceramic fibre. As shown in fig. 25, the front and rear sides of the joint-type fire-resistant reinforced structure 43 are respectively screwed with the indoor layer and the outdoor layer of the unit window (or the outer frame) to reinforce the connection between the two layers of structures. The splice-type refractory reinforcing structure may be identical in shape to the middle refractory reinforcing structure, but disposed at a different location.

In the second connection mode, as shown in fig. 8-10, U-shaped plugging pieces 36 are arranged at openings at two ends of the cavity 3 where the right longitudinal support (or the transverse support) is located, a groove of each U-shaped plugging piece 36 is clamped with the tail end of the reinforcing support 31, and the clamped part of each U-shaped plugging piece 36 and the corresponding reinforcing support 31 is riveted through a pin, so that the stability of the connected part is further enhanced. The U-shaped plugging sheet 36 not only plugs the openings at the two ends of the cavity 3, so that the pouring of the fireproof heat-insulation filling material 32 is facilitated, but also provides a bridge for fixedly connecting the reinforcing bracket 31 with other structures, so that the integral connection of the internal framework structures of the unit windows is facilitated, and the fireproof stability of the whole framework is improved.

The two connection modes can be applied to the corner positions of the unit window and the outer frame according to requirements, for example: the left end and the right end of a frame cross beam of the unit window body shown in fig. 6 are respectively connected with frame longitudinal beams on two sides in the two modes, the corner part of the unit window body, which is spliced with an adjacent unit window body, adopts the second connection mode, and the steel corner connector for the unit window body adopts the first connection mode at the extruded corner part. For example, the upper ends of the outer frame longitudinal beams are corner-connected by a first connection method, the lower ends of the outer frame longitudinal beams are corner-connected by a second connection method, the upper ends of the reinforcing brackets in the outer frame longitudinal beams are inserted into the corner connectors and fixedly connected with the corner connectors, and the lower ends of the reinforcing brackets are inserted into and riveted with the U-shaped plugging pieces 36.

In this embodiment, the reinforcing bracket 31 is fixed in the middle of the cavity 3, and the cross section of the elongated reinforcing bracket 31 is I-shaped, L-shaped or U-shaped.

Corner fire-resistant reinforcing structure

Because the structural stability and the fire resistance of the corner joints of the unit windows are weak, the integral structure of the unit windows collapses under a high-temperature environment due to the structural melting of the corner joints, so that the integral structure is disassembled. Therefore, in order to solve the problems, the invention improves the fire resistance stability of the corner of the window by the following scheme:

as shown in fig. 5, the outer corner fire-resistant reinforcing structure 41 is fixedly attached along the outer wall of the corner of the window frame or the outer frame, and the outer corner fire-resistant reinforcing structure 41 includes an angle iron 411 and a ceramic fiber high-temperature-resistant fireproof cotton strip 412 which are overlapped. In the unit window 2, the ends of the outside corner fire-resistant reinforcing structures 41 are simultaneously screwed with the window frame body 21, the corner connector 5 and the reinforcing brackets 31. In the outer frame, the end of the outside corner fire-resistant reinforcing structure 41 is screwed with the outer frame 1, the corner connector 5 and the reinforcing bracket 31 at the same time. Through outside corner fire-resistant reinforced structure 41, not only further strengthen the joint strength of horizontal structure and longitudinal structure to further carry out the spiro union with frame room outer (or window frame indoor and window frame room outer) in the outer frame room inner layer, show the joint strength and the fire stability who improves the corner junction.

Preferably, as shown in fig. 6, the L-shaped fire-resistant reinforcing structure for the corner portion 41 has two perpendicular wings, each wing is provided with at least two sets of positioning holes arranged in parallel with the long sides of the cross beam or the longitudinal beam, and a set of positioning holes 413 near the intersection of the two wings (i.e. a set of positioning holes on the left side in fig. 6) for the screw connection of the fire-resistant reinforcing structure for the corner portion with the window frame body (or the outer frame), the corner connector 5 and the reinforcing bracket 31 on the same side; a set of positioning holes 414 (i.e. a set of positioning holes on the right side in fig. 6) far from the intersection of the two wings is used for screwing the fire-resistant reinforcing structure on the corner part of the outer side with the window frame body 21 (or the outer frame) and the reinforcing bracket 31 on the same side. Under the high temperature condition, even if the corner brace 5 is melted, the outer corner fire-resistant reinforcing structure 41 can still stably connect the transverse structure and the longitudinal structure of the window frame body or the unit window body, so that the whole window is prevented from being disassembled due to the melting of the corner brace. In the heat insulation type unit window body, each group of positioning holes consists of two positioning holes which are arranged in a row inside and outside, and the two positioning holes in the row are respectively connected with corresponding structures of the outdoor layer and the indoor layer of the window frame body; in the outer frame, two positioning holes in a row are respectively connected with corresponding structures of the outer frame indoor layer and the outer frame indoor layer, and the fire resistance stability of the connection position of the indoor layer and the outdoor layer is enhanced.

Because the fire in the outer layer of the unit window is more violent in fire, it is important to improve the fire resistance of the outer layer. Therefore, an inner corner fire-resistant reinforcing structure 44 is also fixedly arranged at the corner of the inner wall of the outer frame outdoor layer 12 facing the unit window body, so that the structural stability and the fire resistance of the outer frame outdoor layer 12 are improved. The ceramic fiber high-temperature-resistant fireproof cotton strip 412 has the characteristics of excellent heat insulation, softness and compressibility, can effectively reduce heat conduction of the connection part of the unit window, and ensures the heat insulation performance of the whole unit window.
