[0002] To properly solve the problems of peeling and fire of the external wall external thermal insulation pasting system, homogeneous self-insulating blocks (the thickness of the masonry ≤ 350 mm, the thermal conductivity ≤ 0.12 W / (M·K)) are used for the external envelope filling walls in public buildings and residential buildings. For the beam-column parts, a cast-in-place concrete composite external thermal insulation formwork system is generally selected. The practice of the lintel at the opening is as Figure 3 shown.

[0003] When the filled wall uses homogeneous self-insulating blocks as the external envelope structure, precast concrete lintels listed in the existing standard atlas are used for the door and window openings, and it is difficult to eliminate cold bridges. If external thermal insulation materials are pasted outside the lintel, the construction process is complex and the efficiency is low. If the scheme of prefabricated lintels with thermal insulation formwork is adopted, the self-insulating formwork of the lintel needs to be fixed well before the lintel is poured, and the anchor bolts for fixing need to be tied to the lintel steel bars, and then pouring is carried out. The lintel specifications in the existing standard atlas need to be changed greatly. Before the atlas is updated, there is no lintel to choose from, which has a great impact on the design work. Therefore, there is an urgent need for a lintel thermal insulation structure system that can utilize the existing lintel form in the standard atlas, is convenient for construction, and can meet the energy-saving standards at the same time.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0027] As Figure 1 、 2 As shown, the present utility model discloses a fast on-site assembled lintel insulation system, including a precast reinforced concrete lintel 1 and a lightweight insulation board 2. The lightweight insulation board 2 is disposed on the side of the precast reinforced concrete lintel 1, and the precast reinforced concrete lintel 1 and the lightweight insulation board 2 are connected by a connecting piece to form a detachable structure.

[0028] The connecting piece includes a hanging piece 3, and the hanging piece 3 is the main connecting piece between the lightweight insulation board 2 and the precast reinforced concrete lintel 1. The hanging piece 3 is of an S-shaped structure; preferably, the hanging piece 3 is composed of five line segments to form an S-shaped right-angle structure, with one end connected to the top of the precast reinforced concrete lintel 1 and the other end connected to the bottom of the lightweight insulation board 2, firmly fixing the precast reinforced concrete lintel 1 and the lightweight insulation board 2; preferably, a plurality of clamping grooves 5 are provided at the top of the precast reinforced concrete lintel 1, one end of the hanging piece 3 is disposed at the bottom of the insulation board 2, and the other end is connected to the clamping groove 5 to fix the precast reinforced concrete lintel 1 and the lightweight insulation board 2.

[0029] The connecting member further includes a fastener 4. One end of the fastener 4 is arranged on the top of the precast reinforced concrete lintel 1, and the other end is arranged on the top of the light insulation board 2. Together with the hanging part 3, the precast reinforced concrete lintel 1 and the light insulation board 2 are fixed.

[0030] The top surface of the hanging part 3 is flush with the top surface of the fastener 4. The hanging part 3 and the fastener 4 together firmly fix the precast reinforced concrete lintel 1 and the light insulation board 2.

[0031] As Figure 3 shown, it is an existing technical solution. A rapid on-site assembled lintel insulation system includes a reinforced concrete lintel and an external insulation system listed in the existing technology (extracted from the Technical Standard for Application of Self-insulating Blocks XJJ-2019). The external insulation system includes external insulation and the fixing and combining measures between the insulation and the lintel. The fixing structural measures between the external insulation and the lintel include the connecting members used and the on-site construction process, etc. The connecting members are used to firmly fix the insulation board and the lintel together. Through the above structure, cold bridges are eliminated and the insulation performance of the enclosure structure at the lintel is improved.

[0032] Based on the existing technical solution, the further improvement of this application is as follows:

[0033] The reinforced concrete lintel is changed to a factory precast reinforced concrete lintel 1. The precast reinforced concrete lintel 1 can be quickly processed and manufactured in the factory. Its size and quality can be accurately controlled, and it has strong load-bearing capacity. Moreover, the precast reinforced concrete lintel 1 is made by using a formwork, generally using 40% less materials than traditional cast-in-place beams, saving material costs, being less restricted by construction conditions, reducing the amount of on-site wet operation construction, and having a faster construction speed than traditional cast-in-place lintels, saving manpower and time.

[0034] The external insulation system is changed from the original insulation formwork to a light insulation board 2, such as light insulation materials like rock wool, glass wool, extruded polystyrene board or thermosetting composite polystyrene board. The external insulation system is fixed on the top of the precast reinforced concrete lintel 1 or in the card slot 5 arranged on its top through the hanging part 3, which can not only ensure the insulation performance but also reduce the technical requirements for construction workers. The external insulation is installed together with the precast reinforced concrete lintel 1, which can greatly improve the wall masonry speed.

[0035] The connecting member is changed from the anchor bolt supporting the original insulation formwork to the hanging part 3. The hanging part 3 is of an S-shaped structure, and the hanging part 3 firmly fixes the precast reinforced concrete lintel 1 and the light insulation board 2; the fastener 4 is of a U-shaped structure, and the fastener 4 locks the top of the precast reinforced concrete lintel 1 and the light insulation board 2, and the structure is stable and does not fall off.

[0036] All the connecting members are factory-processed parts, and the installation is fast.

[0037] Preferably, the connecting members are all made of metal materials. The selection of this material makes the overall hardness of the connecting members higher, and can fix the precast reinforced concrete lintel 1 and the lightweight thermal insulation board 2 more effectively. At the same time, the selection of the S-shaped right-angle structure and the C-shaped structure is more suitable for the shapes of the lightweight thermal insulation board 2 and the precast reinforced concrete lintel 1, and the connection is tighter.

[0038] In addition, for the precast reinforced concrete lintel 1, the size and reinforcement of the lintel are set according to the national standard atlas "Reinforced Concrete Lintel" G322-1~4. The width of the lintel is the thickness of the self-insulating block - the thickness of the thermal insulation board (for example, if the thickness of the self-insulating block is 350mm and the thickness of the lightweight thermal insulation board is 100mm, then the width of the lintel is 250mm). At the top of the precast reinforced concrete lintel 1, card slots 5 are reserved at intervals for one end of the hanging member 3 to be stuck therein. The positions of the card slots 5 avoid the longitudinal bars and stirrups in the lintel and meet the requirements of the thickness of the steel bar protection layer.

[0039] The thickness of the lightweight thermal insulation board 2 needs to be determined after energy-saving calculation. The length of the lightweight thermal insulation board 2 is equal to the length of the precast reinforced concrete lintel 1. The outdoor side edge of the lightweight thermal insulation board is on the same vertical plane as the outdoor side edge of the self-insulating block. The lightweight thermal insulation board 2 is placed on one end of the hanging member 3 and can be tightly stuck. At the top of the lightweight thermal insulation board 2, a fastener 4 is used to tightly clamp it together with the precast reinforced concrete lintel 1; the hanging member 3 and the fastener 4 are the connecting members between the lightweight thermal insulation board 2 and the precast reinforced concrete lintel 1. The specifications of the connecting members are prefabricated in the factory according to the height of the precast reinforced concrete lintel 1 and the thickness of the lightweight thermal insulation board 2. The thickness of the hanging member 3 can be selected within the range of 4~8mm; the fastener 4 is clamped at intervals on the top of the precast reinforced concrete lintel 1 and the lightweight thermal insulation board 2, and the hanging member 3 and the fastener 4 are arranged at intervals. The connecting members firmly fix the precast reinforced concrete lintel 1 and the lightweight thermal insulation board 2 tightly. The top surface of the fastener 4 is flush with the top surface of the hanging member 3. The net width of the fastener 4 is the same as the width of the self-insulating block filling wall, or slightly wider to meet the requirement of tightly clamping the precast reinforced concrete lintel 1 and the lightweight thermal insulation board 2; the card slots 5 reserved on the precast reinforced concrete lintel 1 are arranged at intervals for fixing the hanging member 3, and the size of the card slots 5 is adjusted in combination with the specifications of the connecting member hanging member 3.
