Description

Technical Field

[0001] The utility model relates to the technical field of building renovation, in particular to an internal renovation structure of a building. Background Art

[0002] With the development of the city, the demand for building structure renovation is increasing. For example, the upgrading renovation of old shopping malls, etc. The renovation content of old shopping malls includes the addition of skywalks and the addition of escalators after opening holes in the floor slabs, etc.

[0003] Taking the example of adding a 6m skywalk at the atrium position of the atrium in an old shopping mall as an example, the existing construction methods for adding a skywalk mainly include two types. One is to add support columns at the cantilever position, but the support columns affect the beauty and space use requirements of the shopping mall; the other is to add a beam at a position 6.4m on the side of the cantilever to form a long-span beam with a length of 20m and connect it to the original beam; due to the large span of the beam, its beam height is also relatively large, and the large beam height affects the beauty and space use requirements of the shopping mall.

[0004] At the same time, taking the example of opening a hole in the floor slab of the shopping mall to add an escalator, since the original beam body of the original frame beam is interrupted by the hole to form a cantilever beam, and the escalator is installed on the cantilever beam. Due to the large load transmitted by the escalator, the cantilever beam needs to be strengthened. Especially on the floors where the skywalk is added, the addition of escalators and skywalks will greatly increase the load of the cantilever beam. The existing construction method is to strengthen the cantilever beam by implanting steel bars into the adjacent column body; however, the steel bars at the beam-column joints are too dense, which is inconvenient for construction, and the anchorage requirements for the steel bars of the cantilever beam are relatively high, and the construction quality cannot be guaranteed.

[0005] Therefore, it is necessary to provide an internal renovation structure of a building, which can solve the problems that the existing schemes of adding skywalks and opening holes in the floor slabs to add escalators in the building affect the beauty and use requirements of the shopping mall and are inconvenient for construction. Summary of the Invention

[0006] The purpose of the utility model is to provide an internal renovation structure of a building, which can solve the problems that the existing schemes of adding skywalks and opening holes in the floor slabs to add escalators in the building affect the beauty and use requirements of the shopping mall and are inconvenient for construction.

One end of the haunch beam is connected to the cantilever end of the cantilever beam, and the other end of the haunch beam is arranged parallel to the in-situ beam and is vertically connected to each longitudinal beam body beside the cantilever beam.

[0013] At the escalator opening position at the bottommost floor, a diagonal bracing between columns is arranged between adjacent column bodies on both sides of the haunch beam and the in-situ beam. The diagonal bracing between columns extends obliquely downward from the longitudinal beam body beside the cantilever beam to the column foundation.

[0017] 2. Since the present utility model is provided with an in-situ beam, a haunch beam and a diagonal bracing between columns, the in-situ beam can play a role in in-situ reinforcement of the cantilever beam, and the cantilever beam is further reinforced by the haunch beam, making the construction more convenient and enabling it to meet the installation and use loads of the escalator. The diagonal bracing between columns is used to transfer the load to the adjacent column foundation, improving the structural safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0027] Please refer to Attachment Figure 1 to Attachment Figure 3, An internal renovation structure of a building, including a transfer beam 1, a strengthened transfer beam 2, an in-situ beam 3, and a haunch beam 4; the transfer beam 1 is arranged at the edge of the cantilevered corridor 6 away from the floor slab, and both ends of the transfer beam 1 are connected to the original longitudinal beam body 701 of its corresponding floor (taking the floor length direction of the building structure as the longitudinal direction and the floor width direction of the building structure as the transverse direction); the strengthened transfer beam 2 is a folded beam structure with a middle bend, the strengthened transfer beam 2 is connected to the transfer beam 1 to form a triangular beam structure, and the middle bend end of the strengthened transfer beam 2 extends to the side where the corridor 6 is connected to the floor slab and the escalator opening position 7 of this floor, and is connected to the original longitudinal beam body 701 and the transverse beam body 702; the in-situ beam 3 is arranged on the cantilever beam 703 at the escalator opening position 7 and is connected to the original longitudinal beam body 701, and the haunch beam 4 is connected between the cantilever beam 703 and the original longitudinal beam body 701 and is located beside the in-situ beam 3.

[0028] During the construction of the cantilevered corridor 6, the triangular beam structure formed by the transfer beam 1 and the strengthened transfer beam 2 replaces the existing long-span beam, which can reduce the length and height of the added beam body, meet the aesthetic and space usage requirements, and the triangular structure has high strength, which can ensure the load-bearing capacity of the cantilevered corridor 6 and also ensure the structural safety at the escalator opening position 7 to a certain extent.

[0029] During the construction of the escalator, the cantilever beam 703 is strengthened in-situ by the in-situ beam 3, and the cantilever beam 703 is further strengthened by the haunch beam 4. It is easy to implement and has low construction difficulty, greatly improving the load-bearing capacity of the cantilever beam 703 so that it can meet the load requirements of the escalator.

[0030] Please refer to the appendix Figure 7 , both ends and the middle bend of the strengthened transfer beam 2 are fixed on the original column 8. The shape of the strengthened transfer beam 2 can be designed in combination with the distribution of the original column 8, and the column 8 at a suitable position can be selected according to the force condition to transfer the load of the cantilevered corridor 6.

[0031] Please refer to the appendix Figure 2 , several auxiliary beams 5 are arranged at the construction position of the cantilevered corridor 6. The auxiliary beams 5 are connected to the original longitudinal beam body 701, and the auxiliary beams 5 intersect and are connected to the strengthened transfer beam 2 and the transfer beam 1.

[0032] Through the setting of the auxiliary beam 5, the auxiliary beam 5 is connected to the longitudinal beam body 701, serves as an extension of the longitudinal beam body 701, and intersects with the strengthened transfer beam 2, further improving the structural strength of the triangular beam.

[0033] Please refer to the appendix Figure 3 , the length of the in-situ beam 3 is the same as the length of the cantilever beam 703, the beam height of the in-situ beam 3 is the same as the beam height of the cantilever beam 703, and the in-situ beam 3 is vertically connected to each longitudinal beam body 701 beside the cantilever beam 703.

[0034] Preferably, the in-situ beam 3 can be connected to the cantilever beam 703 as a whole by the post-inserted bar method of the existing technology. The post-inserted bar method is a common construction technology for in-situ reinforcement of building components, and the construction process thereof will not be elaborated herein. The in-situ beam 3 is constructed adaptively according to the length and beam height of the cantilever beam 703, and the cross-section of the cantilever beam 703 is increased in-situ, thereby improving the bearing capacity of the cantilever beam 703.

[0035] When the transverse beam body 702 is disconnected by a hole to form a cantilever beam 703, the original beam body connected to the side of the cantilever beam 703 is the longitudinal beam body 701. When the in-situ beam 3 is constructed along the cantilever beam 703, the in-situ beam 3 is vertically connected to these longitudinal beam bodies 701 by means such as the post-inserted bar method after passing through each longitudinal beam body 701 perpendicular to the transverse beam body 702.

[0036] Similarly, when the longitudinal beam body 701 is disconnected by a hole to form a cantilever beam 703, the original beam body connected to the side of the cantilever beam 703 is the transverse beam body 702. When the in-situ beam 3 is constructed along the cantilever beam 703, the in-situ beam 3 is vertically connected to these transverse beam bodies 702 by means such as the post-inserted bar method after passing through each transverse beam body 702 perpendicular to the longitudinal beam body 701.

[0037] The specific implementation manner of the present utility model will be specifically described by taking the case where the transverse beam body 702 is disconnected by a hole to form a cantilever beam 703 as an example.

[0038] Please refer to the attached Figure 3 , the haunched beam 4 has an L-shaped structure. One end of the haunched beam 4 is connected to the cantilever end of the cantilever beam 703, and the other end of the haunched beam 4 is arranged parallel to the in-situ beam 3 and is vertically connected to each longitudinal beam body 701 beside the cantilever beam 703.

[0039] The L-shaped haunched beam 4 extends from the cantilever end of the cantilever beam 703 towards the inside of the original frame beam, and can transfer transverse and longitudinal loads, which is beneficial to improving the bearing capacity of the cantilever beam 703, especially the bearing capacity of the cantilever part, so as to ensure the installation and use safety of the escalator.

[0040] Please refer to the attached Figure 4 , at the escalator opening position 7 at the bottommost layer, a diagonal bracing between columns 9 is arranged between adjacent columns 8 on both sides of the haunched beam 4 and the in-situ beam 3. The diagonal bracing between columns 9 extends obliquely downward from the longitudinal beam body 701 beside the cantilever beam 703 to the column foundation below.

[0041] The loads of the escalators on each floor are sequentially transmitted downward through the columns 8, and the loads are transmitted to the adjacent column foundations below through the diagonal bracing between columns 9, improving the structural load capacity and safety.

[0042] Please refer to the attached Figure 5, the diagonal bracing 9 between columns is located within the partition wall, and a decorative cover plate 11 is provided on the partition wall to cover the diagonal bracing 9 between columns, without affecting the aesthetics and construction functions of the building.

[0043] The partition wall can be an original partition wall of the building or a newly constructed partition wall, which is used to hide the diagonal bracing 9 between columns and decorate the partition wall through the decorative cover plate 11. To clearly show the positional relationship between the diagonal bracing 9 and the decorative cover plate 11, attached Figure 5 The decorative cover plate 11 is semi-transparent. During actual construction, various forms of decorative cover plates 11 can be selected according to the decoration requirements to meet the decoration requirements.

[0044] Please refer to attached Figure 1 to attached Figure 7 , the construction method and working principle of the present utility model are as follows:

[0045] When adding the cantilevered connecting corridor 6 in the air, through the triangular beam structure composed of the transfer beam 1 and the strengthened transfer beam 2, not only can the load requirements of the cantilevered connecting corridor 6 be met, but also the lengths and beam heights of the transfer beam 1 and the strengthened transfer beam 2 can be shortened, so as to meet the aesthetic and space usage requirements of the building.

[0046] Both ends and the middle bending points of the strengthened transfer beam 2 are fixed on the original column 8. The two ends of the transfer beam 1 extend into the original frame beam. According to the length direction of the cantilevered connecting corridor 6, if the layout direction of the transfer beam 1 is transverse, the two ends of the transfer beam 1 are connected to the original longitudinal beam body 701, and if the layout direction of the transfer beam 1 is longitudinal, the two ends of the transfer beam 1 are connected to the original transverse beam body 702. The lengths of the transfer beam 1 and the strengthened transfer beam 2, the structural dimensions of the triangle, and the column 8 connected to the strengthened transfer beam 2 can be accurately calculated and determined through building software according to the dimensions and load requirements of the cantilevered connecting corridor 6. The specific construction method of the transfer beam 1 and the strengthened transfer beam 2 adopts existing techniques, and the construction process is not elaborated here.

[0047] At the escalator opening position 7 on the floor where the cantilevered connecting corridor 6 is located, the middle bending position of the strengthened transfer beam 2 extends to the escalator opening position 7, so as to improve the structural safety of the escalator opening position 7 through the strengthened transfer beam 2.

[0048] A transverse beam body 702 that is disconnected at the escalator opening position 7 forms a cantilever beam 703 for installing the escalator. An in-situ beam 3 is installed longitudinally on the cantilever beam 703 to increase the beam section of the cantilever beam 703 in-situ. When the in-situ beam 3 passes through the longitudinal beam body 701, it is disconnected and connected and fixed to each longitudinal beam body 701, so that the in-situ beam 3 is connected to the original frame beam as a whole.

[0049] Install the haunch beam 4 beside the in-situ beam 3. One end of the haunch beam 4 is connected to the cantilever end of the cantilever beam 703, and the other end of the haunch beam 4 is disconnected when passing through the longitudinal beam body 701 and is connected and fixed to each longitudinal beam body 701, so that the haunch beam 4 and the original frame beam are connected into a whole.

[0050] The cantilever beam 703 is reinforced in the same way at the escalator opening positions 7 of each floor slab, and will not be elaborated here one by one. Since the load of the escalator is large, and the in-situ beam 3 and the haunch beam 4 are connected to the longitudinal beam body 701 beside the cantilever beam 703, the load of the longitudinal beam body 701 beside the cantilever beam 703 is correspondingly large. At the escalator opening position 7 at the bottom floor, a temporary support 10 is set at the bottom of the longitudinal beam body 701, and an inclined strut 9 between columns is set between the two adjacent columns 8 on both sides of the longitudinal beam body 701. The upper end of the inclined strut 9 between columns is anchored at the beam-column joint of the longitudinal beam body 701 and one of the columns 8, and the lower end of the inclined strut 9 between columns is anchored at the column foundation of the other column 8, so as to transfer the load to the column foundation.

[0051] The inclined strut 9 between columns can be formed by casting reinforced concrete. Part of the longitudinal beam body 701 and the column foundation at the anchoring position are chiseled to facilitate the connection of steel bars to ensure the connection reliability after anchoring and casting. When setting the temporary support 10, it should be staggered from the construction position of the inclined strut 9 between columns to ensure the normal construction of the inclined strut 9 between columns. After the inclined strut 9 between columns reaches the design strength, the temporary support 10 can be removed. When installing the inclined strut 9 between columns, the partition wall position can be selected for installation to hide the inclined strut 9 between columns, and a decorative cover plate 11 is installed on the partition wall to ensure the reliable shielding of the inclined strut 9 between columns and the indoor decoration effect, and does not affect the use function of the building.

[0052] The above is only the preferred embodiment of the present invention, and is not used to limit the protection scope of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
