For example, the invention patent with the application number of CN2013106966668. X provides a construction method of a cantilever bay window plate concrete integral pouring structure, in the invention, the bay window plate position is reserved in the concrete wall body construction process, the upper bay window plate, the window upper connecting beam and the upper floor slab are poured simultaneously, the lower bay window plate and the upper part of the window lower connecting beam are poured simultaneously, and the construction method can be applied to the construction of the non-floor type bay window of the cast-in-place concrete shear wall structure house.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. The technical characteristics in the embodiments of the present invention can be combined correspondingly without mutual conflict.

In the description of the present invention, it is to be understood that the terms "first", "second" and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the description of the present invention, it should be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be indirectly connected to the other element, i.e., intervening elements may be present. In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.

In the integrally prefabricated embedded bay window provided by the invention, two types of forms exist, and the difference is that the forms of the bay window plates are different. The first type is a bay window plate with an L-shaped section, and the second type is a bay window plate with a straight line shape. Two types of integrally prefabricated embedded bay windows will be described below to facilitate understanding of the implementation of the present invention.

In one embodiment, an integrally prefabricated embedded bay window of the first type is provided, and referring to fig. 1 and 2, a main structure of the integrally prefabricated embedded bay window specifically includes a bay window top plate 2, a bay window bottom plate 3 and two vertical columns 1. The column 1 is a concrete column with built-in steel components, the steel components in the column are arranged along the center of the column in a through length mode, and the section form of the concrete column needs to be determined according to the design requirements of buildings. The form of the steel component in the column is not limited, for example, the steel component can be formed by binding steel bars meeting the strength requirement, and the steel component can also be formed by matching profile steel with the steel bars. In the embodiment, the steel member in the column 1 is the i-beam 101, the reinforced concrete is wrapped outside the i-beam 101, and the concrete parameters of the steel bar 105 and the concrete 106 are designed according to the relevant specifications, so that the section steel concrete column with the square section is formed. The structure of the i-beam 101 is shown in fig. 3, wherein a top hanging connecting piece for connecting with the bottom surface of the external upper frame beam 6 is fixed at the top end of the steel member, and a bottom bracing connecting piece for connecting with the top surface of the floor slab 8 is fixed at the bottom end of the steel member.

Here, the top hanging connector is a connector for hanging the whole column 1 on the bottom surface of the upper frame beam 6 with the top surface thereof in contact with the bottom surface of the outer upper frame beam 6, and is intended to fix the column 1 between the upper frame beam 6 and the floor slab 8 in a built-in manner. The top-hung connector is not limited as long as it has sufficient strength and has a top surface capable of being in close contact with the bottom surface of the upper frame rail 6. The top-hung connecting piece adopted in the embodiment is an upper end plate 102 horizontally fixed at the top of a steel member, and the upper end plate 102 can be directly welded and fixed at the top end of an I-shaped steel 101 by adopting a steel plate. In practical engineering, high-strength bolts are generally used to fix upper end plate 102 and upper frame beam 6, so that a number of first bolt holes need to be formed in upper end plate 102 in advance, the number of first bolt holes depends on the number of required bolts, and in this embodiment, 4 bolt holes are provided in total. Since the i-beam 101 is finally wrapped by concrete, a threaded sleeve 107 needs to be coaxially fixed to each first bolt hole in order to facilitate the smooth screwing of the bolt into the upper end plate 102 during subsequent installation. Threaded sleeve 107 may be welded directly to the bottom surface of upper end plate 102, with its internal threads mating with the high-strength bolts used for installation.

Here, the bottom-brace connector means a connector capable of being connected to the floor slab 8 directly or indirectly, thereby integrally supporting the column 1 on the top surface of the floor slab 8. The form of the bottom support connecting piece is not limited, and the bottom support connecting piece can be matched with the top hanging connecting piece to realize the limiting fixation and the vertical load bearing of the bottom of the built-in upright post 1. In this embodiment, the bottom brace connecting piece includes a lower end plate 103 and a lower connecting plate 108, the lower end plate 103 is horizontally welded and fixed to the bottom of the i-beam 101, and the lower connecting plate 108 is vertically fixed to the bottom surface of the lower end plate 103. The lower end plate 103 can be directly welded and fixed at the bottom end of the I-shaped steel 101 by adopting a steel plate. Similarly, similar to the fixing mode of the top-hung connecting piece, in practical engineering, a high-strength bolt is generally adopted to fix the bottom-support connecting piece and the floor slab 8 or the embedded fixing piece on the floor slab 8, so that the second bolt hole needs to be formed in advance on the lower connecting plate 108. The number of the second bolt holes is determined according to the number of the required bolt pieces, and 2 bolt holes are provided in the present embodiment.

In addition, in the present embodiment, in order to facilitate integral hoisting of the bay window member, it is preferable that a hoisting connector 104 is fixedly connected to the web of the i-beam 101. The hoisting connecting piece 104 can be realized by selecting different structures according to hoisting forms, in this embodiment, the hoisting connecting piece 104 is realized by using an internal thread sleeve, one end of the internal thread sleeve is welded and fixed on the web plate of the i-steel 101, and the other end of the internal thread sleeve is an open end, and the open end is located on the concrete surface of the upright post 1. In the subsequent hoisting process, the external thread fixing piece used for hoisting can be conveniently screwed into the opening of the internal thread sleeve, and then hoisting is carried out. After the hoisting is finished, the external thread fixing piece can be unscrewed again, the concrete surface of the upright post 1 is blocked and plastered, and the internal thread sleeve is hidden. Of course, in other embodiments, the hoisting connector 104 may be eliminated if the integral hoisting of the bay window does not require the setting of a hoisting point.

Two posts 1 serve as fixed carriers for the entire bay window, which need to be maintained in a parallel and spaced arrangement. The interval between two stands 1 needs to be decided according to the span of whole window that wafts, and two stands 1 are located the both sides of window body that wafts respectively, play the effect of bearing the vertical weight of window body that wafts. Similar to the traditional bay window, the bay window top plate 2 and the bay window bottom plate 3 are also arranged on the two upright posts 1 in an overhanging manner, the bay window top plate 2 is arranged above the bay window bottom plate 3, the bay window top plate 2 and the bay window bottom plate 3 are required to be arranged on the same side of the plane of the two upright posts 1, and the distance between the bay window top plate 2 and the bay window bottom plate 3 is determined according to the design parameters of the bay window.

The bay window top plate 2 and the bay window bottom plate 3 in the embodiment both adopt bay window plates with L-shaped cross sections, and the L-shaped cross section means that the cross section of the bay window plates from the fixed end to the overhanging end is L-shaped. The bay window top plate 2 is of a reinforced concrete structure consisting of a fixed end and a cantilever plate, the fixed end of the bay window top plate is turned upwards relative to the cantilever plate, and the cross section of the bay window top plate 2 is in a regular L shape. The thickness of stiff end equals with stand 1's thickness, and the reinforcing bar of stiff end passes through ligature welded fastening with the reinforcing bar in two stands 1, and the concrete body of bay window roof 2 and stand 1 is pour. Similarly, the bay window bottom plate 3 is also of a reinforced concrete structure consisting of a fixed end and a cantilever plate, and is different in that the fixed end is turned down relative to the cantilever plate to avoid occupying the space between the two bay window plates, and the bay window bottom plate 3 has an inverted L-shaped cross section. The thickness of its stiff end also equals with the thickness of stand 1, and the reinforcing bar of stiff end and the reinforcing bar in two stands 1 pass through ligature welded fastening, and the concrete body of window bottom plate 3 and stand 1 pours that wafts.

In the integrally prefabricated embedded bay window, a clamping space between a bay window top plate 2 and a bay window bottom plate 3 is used as a bay window space, three sides of the space are outwards cantilevered relative to the plane of two upright posts 1, and the other side is the plane of the two upright posts 1. In the traditional bay window, three overhanging sides need to be subjected to field operation, which can greatly increase the time required for installing the bay window and the difficulty of the field operation. Therefore, in the embodiment, three sides of the overhanging window space are directly surrounded by the outer vertical surface of the bay window in a factory, and the rest side is open, so that a prefabricated outward protruding bay window body is formed, redundant processing of the outer vertical surface is not needed in the subsequent hoisting process, and the process and time required by the installation of the bay window are greatly simplified. For the floating window body, the fixed end of the top plate 2 of the floating window, namely the other end far away from the overhanging end, is connected with the two upright posts 1 into a whole, the fixed end of the bottom plate 3 of the floating window is also connected with the two upright posts 1 into a whole, so that the whole floating window body and the upright posts 1 on the two sides form a stress system, and the weight of the whole floating window body is borne by the upright posts 1 on the two sides.

In the integrally prefabricated embedded bay window, the specific form of the outer vertical surface of the bay window can be determined according to design drawings, and the whole or part of the bay window can be a glass window 5. Specifically, the three side facades may be the same or different, and the facades of each book may be all walls, or partial wall glass windows, or whole glass windows. In view of the lighting and aesthetic requirements of the fenestration, in a preferred embodiment, all three-sided facade is designed as a glazing. When the outer vertical surface is provided with the glass window, the window frame of the bay window which is completed by assembling the frame can be installed on the outer vertical surface as required in a factory, the window sashes can be installed on the window frame before being hoisted, and the bay window can also be installed after the whole bay window is hoisted to a target position for installation. Under the condition that the hoisting safety requirements can be met, the window sashes are preferably installed in a factory together, and only need to be hoisted on site directly, so that the construction procedures are reduced.

Meanwhile, in order to further reduce the working procedures and time required by site construction, the height of the upper edge and the lower edge of the whole bay window is controlled, so that the top plate 2 of the bay window can be jointed with the upper frame beam 6 after the bay window is integrally hoisted and installed, and the wall body at the lower part of the bottom plate 3 of the bay window can be jointed with the floor slab 8, thereby avoiding the situation that the site pouring is required. Therefore, the upper edge of the fixed end of the bay window top plate 2 of the present invention needs to be kept flush with the mounting surfaces of the two side hanging connectors, which are both the upper end plate 102 in this embodiment, so the mounting surface is the top surface of the upper end plate 102. Under the method, the upper edge of the fixed end of the bay window top plate 2 can be directly attached to the lower bottom surface of the upper frame beam 6 after the bay window is installed, and extra wall body pouring is not needed. In addition, the wall body at the lower part of the bay window bottom plate 3 also needs to be controlled for the bottom elevation, but the form of the bay window determines that the conventional bay window bottom plate 3 needs to keep a certain distance from the surface of the floor 8, so the fixed end of the bay window bottom plate 3 is designed to be suspended relative to the bottom ends of the two upright posts 1, and the space between the two upright posts 1 below the fixed end of the bay window bottom plate 3 is filled with the wall body. Because the weight of the concrete poured bay window bottom plate 3 is larger, the space between the two upright posts 1 and below the fixed end of the bay window bottom plate 3 is filled with the wall plate 4, and the lower edge of the wall plate 4 is kept flush with the bottom ends of the bottom support connecting pieces at the two sides, so that the lower edge of the wall plate 4 below the bay window bottom plate 3 can be directly attached to the surface of the floor slab 8 after the bay window is installed, and no additional wall body pouring is needed.

It should be noted that the level in the present invention does not necessarily require the level of the two to be completely consistent, and the level state may also allow certain errors in consideration of the inevitable errors in construction.

In another embodiment, the embedding of the edge seams between the window frame and the bay window top plate 2, the bay window bottom plate 3 and the upright posts 1 can be realized by using adhesive tapes so as to improve the impermeability and air tightness of the part of the joint

In another embodiment, wall panel 4 is preferably a lightweight wall panel to minimize weight while maintaining overall strength.
