Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an integrated installation structure and construction method for high-suspension decorative beams that can be converted from cast-in-place to prefabricated. Background Technology

[0002] To enhance the aesthetic appeal of high-rise residential buildings, suspended decorative concrete beams are often installed. The common practice is to use cantilevered I-beams with lower supports, upper tensioning, and formwork. This method is not only technically complex and costly, but also involves working at heights, posing significant safety hazards. While steel beams are simpler to install than suspended decorative concrete beams, the subsequent enclosure costs are high, and safety risks may arise over time.

[0003] The installation and dismantling of high-altitude cantilever formwork is challenging. An operating platform needs to be erected at the lower support of the I-beams, and collisions with the external scaffolding are inevitable during installation, requiring adjustments to the scaffolding's crossbars. Furthermore, high-altitude work poses significant safety hazards and makes it difficult to guarantee installation quality. After the high-altitude cantilever formwork is erected, it cannot be dismantled until the decoration work in the area is completed, resulting in a long period of time occupied by the scaffolding and making it uneconomical. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides an integrated installation structure and construction method for high-suspension decorative beams that can be converted from cast-in-place to prefabricated. This integrated decorative beam, provided the on-site tower crane lifting capacity meets the requirements, is constructed using a method of overall prefabrication, integrated decoration, and one-time hoisting. This fully utilizes the efficiency of existing on-site equipment, improves construction quality and progress, avoids the need for erecting high-altitude work platforms, reduces high-altitude operations, ensures construction safety, and saves time and costs.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0006] An integrated installation structure for high-suspension decorative beams, transitioning from cast-in-place to precast construction, includes a pair of cast-in-place beams. Precast beam support walls are cast at the ends of each pair of cast-in-place beams. Precast beams are installed between the precast beam support walls. Partially integrated steel plates are embedded at both ends of each precast beam. The exposed portions of the integrated steel plates are embedded within the core area of ​​the precast beam support walls. Support components for preventing the precast beams from overturning are installed on the precast beam support walls. Round-headed hanging nails are also embedded at the top of both ends of the precast beams.

[0007] Preferably, the integrated steel plate includes a connecting steel plate, a steel pad, and multiple studs. The steel pad is welded to the bottom of the exposed portion of the connecting steel plate, and the multiple studs are evenly distributed and welded to both sides of the embedded portion of the connecting steel plate.

[0013] This invention also provides a construction method for converting cast-in-place to precast integrated installation structure of high-suspension decorative beams, including the following specific steps:

[0014] S1. Precast beam fabrication: After the drawings are refined, the steel cage of the beam is tied. An integrated steel plate is fabricated on site, and part of it is embedded in both ends of the steel cage. Then, two round-headed hanging nails are embedded in the top of both ends of the steel cage. After the formwork is set up around the steel cage, concrete is poured and cured. The decorative surface is then constructed on the precast beam.

[0015] S2. Precast beam hoisting:

[0016] When the bottom elevation of the cast-in-place beam is greater than or equal to the bottom elevation of the precast beam, the following fixing and support methods shall be adopted:

[0017] A. Positioning and layout: In the precast beam support wall column, according to the design requirements of the structural drawings and the position of the precast beam, mark out the position of the pre-embedded bolts;

[0018] B. Embedded threaded rods: Verify the location and install multiple threaded rods into the steel mesh tied to the precast beam support wall column, and fix them firmly;

[0019] C. First concrete pouring for precast beam support wall columns: Erect wall column formwork and pour concrete to the bottom elevation of the precast beam, which is the first pouring surface. The area above the first pouring surface is the second pouring area.

[0020] D. Roughening, cleaning, and leveling: After the concrete strength of the wall column reaches 50%, remove the wall column formwork and roughen, clean, and level the first pouring surface according to the elevation.

[0021] E. Fabrication and installation of steel bracket clamps: Steel bracket clamps are fabricated on-site by welding, and the fabricated steel bracket clamps are connected to the pre-embedded bolts and fastened with double nuts;

[0022] F. Precast beam hoisting: After the concrete strength of the wall column reaches 100%, the precast beam is hoisted by tower crane and round-headed lifting nails. The integrated steel plates exposed at both ends of the precast beam are placed on the corresponding first pouring surface and located in the second pouring area. The two flange steel plates of the steel bracket clamp hold the ends of the precast beam.

[0023] G. Second concrete pouring for precast beam support wall columns: After hoisting is completed, pour the remaining concrete on the first pouring surface, i.e., in the second pouring area, and cure it.

[0024] When the bottom elevation of the cast-in-place beam is lower than that of the precast beam, the following fixing and support methods shall be adopted:

[0025] A. Positioning and layout: In the precast beam support wall column, position and layout the support members according to the design requirements of the structural drawings;

[0026] B. Embedded support members in walls and columns: The steel pipes of the support members are embedded in the reinforcing mesh of the precast beam support wall and column, and fixed firmly.

[0027] C. First concrete pouring for precast beam support wall columns: Erect wall column formwork and pour concrete to the bottom elevation of the cast-in-place beam, which is the first pouring surface. The supporting steel plate of the support members is higher than the first pouring surface and is consistent with the bottom elevation of the precast beam.

[0028] D. Precast beam hoisting: After the concrete strength of the wall column reaches 100%, the precast beam is hoisted using a tower crane and round-headed lifting nails. The steel pads at the bottom of the integrated steel plates exposed at both ends of the precast beam are placed on the corresponding support steel plates and fully welded.

[0029] E. Second concrete pouring for precast beam support walls and columns: After hoisting is completed, pour the remaining concrete on the surface of the first pouring and cure it.

[0030] Preferably, the integrated steel plate has a total length of 1300mm, is centrally embedded in the reinforcing cage, 800mm is embedded in the precast beam, and 500mm is exposed and embedded in the core area of ​​the wall column.

[0031] Preferably, the multiple studs on both sides of the integrated steel plate are welded to the stirrups in the reinforcing cage.

[0032] The beneficial effects of this invention are as follows:

[0033] 1. Provided that the lifting capacity of the tower crane on site meets the requirements, the high-suspension decorative beams are constructed using the method of overall prefabrication, integrated decoration, and one-time hoisting. This can make full use of the efficiency of the existing equipment on site, improve the construction quality and progress, avoid the construction of high-altitude work platforms, reduce high-altitude work, ensure construction safety, and save construction time and costs.

[0034] 2. By setting an integrated steel plate, it can provide support when the precast beam is hoisted to the wall column support, and can also strengthen the connection between the precast beam and the core area of ​​the wall column support.

[0035] 3. By setting steel bracket clamps, it is applicable to cast-in-place beams with a bottom elevation greater than or equal to that of precast beams. It can play an auxiliary support role when the precast beam is hoisted to the wall column support, and can also play an anti-overturning role after the precast beam is hoisted.

[0036] 4. By setting up support rods, the support steel plates of the support rods are fully welded to the steel pads of the integrated steel plates, which not only serve as construction supports, but also as an anti-overturning function for the precast beams. Attached Figure Description

[0056] When the bottom elevation of the cast-in-place beam 1 is lower than that of the precast beam 2, the support assembly adopts the form of support rod 8. The support rod 8 is embedded in the precast beam support wall column 3. The support rod 8 includes a steel pipe 81 and a support steel plate 82. The steel pad 62 is welded on the support steel plate 82. It not only serves as a construction support but also as an anti-overturning function for the precast beam.

[0057] Furthermore, the dimensions of the supporting steel plate 82 are the same as those of the steel pad 62, and the supporting steel plate 82 and the steel pad 62 are fully welded together.
