Description

Technical Field

[0001] The invention relates to the technical field of prefabricated colonnades, and in particular to a prefabricated plain concrete colonnade structure. Background Art

[0002] The colonnade system, as the crystallization of ancient architectural wisdom, has transcended time and space with its unique charm and still occupies an important position in architectural art. The colonnade, that is, the corridor composed of columns, not only bears the weight of the building structure, but also gives the building a smart vitality with its elegant lines and open sense of space. In modern urban design, the colonnade system has been given new life. It is not only a bridge connecting indoor and outdoor spaces, but also a witness to urban culture and history. Through clever use, the colonnade system can create a spatial atmosphere that is both classical and modern, adding a unique charm to the city. Whether in the protection and renewal of historical blocks or in the planning and construction of new areas, the colonnade system has become a bridge connecting the past and the future with its unique charm.

[0003] When constructing modern colonnade systems, most tend to use cast-in-place concrete. The construction process of cast-in-place concrete colonnades is quite complicated, requiring multiple steps such as sophisticated formwork making, steel bar binding, and concrete pouring. More importantly, after the cast-in-place concrete colonnades are cast and formed, there are often molding quality problems such as insufficient surface flatness, many bubbles, and large color differences. This not only affects the aesthetics of the colonnade, but also reduces its overall architectural quality. Therefore, after casting and forming, a series of appearance processing work is required, such as polishing, repairing, spraying, etc., which further increases the overall construction cost. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a prefabricated plain concrete colonnade structure, which solves the problem in the prior art that the cast-in-place concrete colonnade has various defects on the colonnade surface after molding, which requires subsequent further treatment and increases the construction period and construction cost.

[0005] According to an embodiment of the present invention, a prefabricated plain concrete colonnade structure includes a base, a prefabricated parapet, and a drainage member. There are multiple bases, each of which is provided with a slot on the top, and a prefabricated column is vertically inserted in the slot of each base. There are multiple prefabricated parapets, which are horizontally erected on the top of the prefabricated column. Each prefabricated parapet includes a bearing platform and a hanging plate, which is arranged on one side of the bearing platform and is integrally formed with the bearing platform. The bearing platform is connected to the top of the prefabricated column. One side of the bearing platform of the prefabricated parapet is connected with a plurality of prefabricated main beams and prefabricated small beams at staggered intervals by cast-in-place concrete. Prefabricated panels are erected on the top of the prefabricated main beams and prefabricated small beams. Drainage members are arranged on the prefabricated columns, and the drainage members are used to drain the accumulated water on the top of the prefabricated panels to the ground.

[0006] Compared with the prior art, the present invention has the following beneficial effects: by prefabricating the multiple components that make up the colonnade, the prefabricated prefabricated parapet, prefabricated column, prefabricated main beam and prefabricated small beam and other components are assembled on site, the prefabricated column is inserted into the slot of the base to provide support for the prefabricated parapet, the prefabricated main beam and the prefabricated small beam are connected to one side of the bearing platform to provide support for the prefabricated board, and the drainage parts can also drain the accumulated water on the prefabricated board to the ground on rainy days to avoid water accumulation. After the various components are assembled by cast-in-place concrete, a colonnade structure is formed, which greatly reduces the construction period. At the same time, there is no need to repair the colonnade structure later, which reduces the cost.

[0007] Furthermore, the drainage component is a downpipe, which is pre-buried in the prefabricated column. A through hole is opened on the prefabricated plate, one end of the downpipe is connected to the through hole, and the other end of the downpipe extends vertically downward into the slot and then passes through the base.

[0008] Furthermore, a slope is provided on the top of the hanging board, and the slope is inclined downward along the direction of the prefabricated board.

[0009] Furthermore, a step is provided on the side of the bearing platform away from the hanging plate.

[0010] Furthermore, the slot has a trumpet-shaped structure that is larger at the top and smaller at the bottom.

[0011] Furthermore, a grouting hole is provided through the bottom of each prefabricated column.

[0012] Furthermore, a mounting groove is provided on the top of each prefabricated main beam, and support beams are provided on both sides of each prefabricated small beam, and one end of each branch beam away from the small beam is overlapped in the mounting groove.

[0013] Furthermore, each prefabricated main beam, each prefabricated small beam and the bearing platform are pre-embedded with connecting steel plates through connecting ribs.

[0014] Furthermore, waterproof material is filled between the prefabricated plate and the bearing platform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, an embodiment of the present invention proposes a prefabricated plain concrete colonnade structure, including a base, a prefabricated parapet, and a drainage member. There are multiple bases, each of which is provided with a slot on the top, and a prefabricated column is vertically inserted in the slot of each base. There are multiple prefabricated parapets, which are horizontally erected on the top of the prefabricated column. Each prefabricated parapet includes a bearing platform and a hanging plate, which is arranged on one side of the bearing platform and is integrally formed with the bearing platform. The bearing platform is connected to the top of the prefabricated column, and one side of the bearing platform of the prefabricated parapet is connected with a plurality of prefabricated main beams and prefabricated small beams at staggered intervals by cast-in-place concrete. Prefabricated panels are erected on the top of the prefabricated main beams and prefabricated small beams. The drainage member is arranged on the prefabricated column, and the drainage member is used to drain the accumulated water on the top of the prefabricated panel to the ground. During construction, the prefabricated components are transported to the construction site. The base can be prefabricated or cast-in-place. After positioning, the prefabricated column is hoisted by a crane, and the prefabricated column is suspended from horizontal to vertical with the bottom end of the prefabricated column as the axis. The crane moves the prefabricated column to the top of the slot of the base and then puts the prefabricated column into the slot. Then, self-compacting concrete is poured into the slot. After the self-compacting concrete reaches the designed strength, the prefabricated parapet is hoisted to the top of the prefabricated column and fixed. The specific fixing method can be cast-in-place concrete, bolts, etc. Then, the prefabricated main beam and prefabricated small beam are connected on one side of the bearing platform. In this embodiment, the precast main beam and the precast small beam are connected by cast-in-place concrete. When the cast-in-place concrete does not reach the designed strength, the precast main beam and the precast small beam are auxiliary supported. Finally, the precast panel is installed on the top of the precast main beam and the precast small beam. The drainage parts guide the accumulated water on the top of the precast panel to the ground to avoid the accumulation of water on the top of the precast panel. By prefabricating various components and assembling them at the construction site, the efficiency of the construction corridor system is improved to ensure the quality of the corridor system, and the subsequent extra time for grinding and repairing the corridor is avoided, thereby reducing the construction cost.

[0023] Furthermore, the drainage component is a downpipe, which is pre-buried in the prefabricated column. A through hole is provided on the prefabricated plate, one end of the downpipe is connected to the through hole, and the other end of the downpipe extends vertically downward into the slot and then passes through the base. In this embodiment, downpipes are pre-buried in some prefabricated columns. When making the prefabricated column, the downpipe is pre-buried in the prefabricated column, and a connecting groove for the downpipe to pass through is pre-opened at the connection between the bearing platform and the prefabricated column, so that the end of the downpipe extending out of the prefabricated column will not interfere with the bearing platform. At the same time, when installing the prefabricated main beam and the prefabricated small beam, one end of the prefabricated main beam or the prefabricated small beam can be inserted into the connecting groove and then cast in situ concrete in the connecting groove, so that the connection between the prefabricated main beam, the prefabricated small beam and the bearing platform is more stable. It should be noted that a reserved hole is provided on the base for the downpipe to pass through.

[0024] Furthermore, a slope is provided on the top of the hanging board, and the slope is inclined downward along the direction of the prefabricated board. The slope on the top of the hanging board plays a role in aesthetic appearance and allows rainwater to flow into the inside of one side of the prefabricated board.

[0025] Furthermore, a step is provided on the side of the bearing platform away from the hanging plate. When the prefabricated main beam or prefabricated small beam is connected to the bearing platform, one end of the prefabricated main beam or prefabricated small beam is placed on the step to play a supporting role, so as to facilitate the subsequent connection of the prefabricated main beam or prefabricated small beam to the bearing platform.

[0026] Furthermore, the slot is in a trumpet-shaped structure with a larger upper part and a smaller lower part. After the prefabricated column is inserted into the slot, since the slot is in a larger upper part and a smaller lower part structure, the remaining part of the space is used for concrete pouring, so that the prefabricated column and the base can be connected more firmly.

[0027] Furthermore, a grouting hole is provided through the bottom of each prefabricated column. In this embodiment, when pouring concrete into the slot, the poured concrete can flow into the grouting hole. Specifically, when pouring concrete, the concrete is poured from one side of the slot, and the concrete flows into the other side through the grouting hole until the concrete overflows from the other side. Then, reasonable maintenance can be performed, thereby further improving the connection strength between the base and the prefabricated column.

[0028] Furthermore, each prefabricated main beam is provided with a mounting groove on the top, and each prefabricated small beam is provided with supporting beams on both sides, and one end of each supporting beam away from the small beam is overlapped in the mounting groove. After the prefabricated main beam is connected to the bearing platform, the supporting beams on both sides of the prefabricated small beam are overlapped in the mounting grooves of the main beams on both sides thereof, and the connection between the supporting beam and the prefabricated main beam can be made by cast-in-place concrete or by bolts.

[0029] Furthermore, each prefabricated main beam, each prefabricated small beam and the bearing platform are pre-embedded with a connecting steel plate through connecting ribs. The bearing platform is pre-embedded with a connecting steel plate at the designed position. When the prefabricated main beam or prefabricated small beam is connected to the bearing platform, the connecting steel plate on the prefabricated main beam or prefabricated small beam is welded to the connecting steel plate on the bearing platform, and then the prefabricated main beam or prefabricated small beam is auxiliary supported, and then cast-in-place concrete is poured at the connection between the prefabricated main beam and the bearing platform to connect the two. By welding the connecting steel plate of the bearing platform to the connecting steel plate of the prefabricated main beam or prefabricated small beam, the prefabricated main beam or prefabricated small beam is prevented from deflecting during the solidification process of the cast-in-place concrete.

[0030] Furthermore, waterproof material is filled between the prefabricated board and the bearing platform. The waterproof material may be waterproof concrete, waterproof mortar, waterproof roll material, etc., to prevent the accumulated water on the top of the prefabricated board from leaking to the bottom and affecting the user experience.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
