Description

Technical Field

[0001] The utility model belongs to the field of construction elevator wall-attached frames, in particular to a narrow-body steel wall-attached frame connection structure of an upper inverted beam roof construction elevator. Background Art

[0002] With the rapid development of the construction industry, construction elevators, as the main vertical transportation tool for masonry and decoration projects, have an important impact on ensuring construction safety and improving work efficiency. In recent years, the design of high-rise residential roofs has been gradually optimized, and the frame beams of some high-rise residential roofs have been simplified, resulting in the inability of construction elevators to meet the needs of going up to the roof. Construction materials need to be transported to the roof layer. When the construction elevator needs to go up to the roof, the distance between the two attachments or the free end of the top standard section exceeds the requirements of the specifications and instructions, additional attachment rods need to be added. When there is no structure on the roof for attachment, a temporary fixing device for the construction elevator wall rod needs to be added.

[0003] In order to solve the above problems, the prior art, such as CN215905656U, proposes a construction elevator roof wall fixing device, which has the following problems during use:

[0004] 1. The width of the roof support is too wide. The overall width exceeds the sum of the widths of the standard section of the steel frame and the construction elevators on both sides. When workers transport construction materials from the car to the roof panel, the roof support is in the form of a gantry above the construction elevator. It is disturbed by the long horizontal beam, which will cause inconvenience in unloading construction materials.

[0005] Second, the total volume of the roof support is too large and the amount of steel used is too much, resulting in cumbersome installation steps and unnecessary waste of steel.

[0006] 3. The bottom of the roof support column causes the roof panel to be subjected to greater force. At the same time, the bottom of the column is easily contaminated when the construction materials are unloaded. In addition, the end of the roof panel is often provided with an upper reverse beam. This structure will not guarantee the safety of the construction workers.

[0007] 4. The roof support has three vertical poles, which need to be precisely positioned and aligned, and the embedded parts at the bottom of the vertical poles need to be buried before the roof concrete is poured. The roof concrete pouring process will generate impact loads, causing the vertical hook-shaped threaded steel to shift, which in turn causes errors in the installation of the steel frame positioning embedded plate, making it impossible to completely accurately determine the plane position of the column.

[0008] 5. The horizontal beam of the roof support needs to be installed eccentrically when installed on the column to reserve space for the top of the diagonal rod to be bolted to the top of the column. However, the eccentric installation will cause the column to be eccentrically stressed and the overall stability of the support will be poor. Utility Model Content

[0009] The purpose of the utility model is to provide a narrow-body steel wall-mounted frame connection structure for an elevator with an upper inverted beam roof construction, which is intended to solve the technical problem that the existing wall-mounted fixing device is too wide, resulting in inconvenient operation when unloading construction materials; and to solve the technical problem that the total volume of the device is too large and the amount of steel used is too much, and the technical problem that the embedded parts at the bottom of the vertical pole are prone to installation errors, resulting in inaccurate positioning, and the technical problem that the eccentric installation of the horizontal beam causes eccentric force on the column, resulting in poor overall stability of the bracket.

[0024] The reinforcement of the additional inverted beam includes the main reinforcement of the inverted beam and the stirrups of the inverted beam, and the bottom of the stirrups of the inverted beam is fixedly connected to the roof steel mesh.

[0025] The columns and inclined columns are all I-beams. The horizontal tension beam at the top of the column is an H-shaped steel welded by steel plates, including the front flange plate of the tension beam, the web plate of the tension beam and the rear flange plate of the tension beam. The web plate of the tension beam is vertically arranged and perpendicular to the column. The front flange plate of the tension beam and the rear flange plate of the column are tightly attached and welded together to form a connecting bracket.

[0026] The column top connection assembly includes an inclined column top connection plate and an inclined column connection bolt. The inclined column top connection plate is vertically arranged and fixedly connected to the column top of the inclined column. The inclined column top connection plate is tightly attached to the rear flange plate of the tension beam and is anchored by the inclined column connection bolts.

[0027] A tension beam stiffening plate is arranged in a C-shaped groove formed by the tension beam front flange plate, the tension beam web plate and the tension beam rear flange plate.

[0028] The horizontal rooting beam of the wall rod is an I-beam, including the upper flange plate of the rooting beam, the web plate of the rooting beam and the lower flange plate of the rooting beam.

[0029] The column top is fixedly connected with a horizontal column top connection cover plate, and the column top connection cover plate is tightly attached to the lower flange plate of the rooting beam and is anchored by the rooting beam connection bolts.

[0030] The bottoms of the vertical columns and inclined columns are fixedly connected with horizontal column bottom plates, and the column bottom plates are provided with column bottom plate holes for the column bottom embedded connection components to pass through.

[0031] The column bottom embedded connection assembly includes two U-shaped positioning screws, two pressure foot steel bars and positioning nuts.

[0035] The protective cover plate structure is a man-accessible formwork panel.

[0036] Compared with the prior art, the utility model has the following characteristics and beneficial effects:

[0037] The utility model abandons the existing roof support width, designs a narrow roof support, limits the width of the roof support within the standard section range, releases the roof support in front of the car, and is easy to operate when unloading construction materials without being interfered by the roof support.

[0038] The narrow roof support of the utility model reduces the amount of steel used and saves steel materials.

[0039] In order to ensure the overall stability of the narrow roof support and the connection between the support and the roof panel, the utility model designs an additional upper inverted beam corresponding to the upper inverted beam at the end of the roof panel. The additional upper inverted beam is constructed integrally with the roof panel, and the two ends of the additional upper inverted beam are connected to the structural force frame, so that the load of the roof panel is dispersedly transmitted to the structural force frame by the additional upper inverted beam, and the force effect is better. At the same time, for the construction safety of the workers at the position of the upper inverted beam at the end of the roof panel, the height of the additional upper inverted beam is designed to be the same height as the upper inverted beam at the end of the roof panel, and then the upper panel is laid to form an upper platform, which is convenient for workers to walk between the construction elevator and the roof and serves as a dust cover protection. Warning tapes are set on the column bottom bolts of the vertical column and the inclined column to facilitate the pouring personnel to avoid contaminating the upper threads when pouring the roof panel concrete.

[0040] The vertical column and the inclined column of the utility model are connected to the roof panel by adopting the pre-embedded connection assembly at the bottom of the column. The existing vertical positioning screw is designed into a U shape in the pre-embedded connection assembly at the bottom of the column, and pre-embedded pressure foot steel bars are added, so that the U-shaped positioning screw can be stabilized when the roof panel concrete is poured, avoiding the installation error of the pre-embedded connection assembly at the bottom of the column, and ensuring the accurate planar position of the column.

[0041] The utility model further arranges a column top horizontal tension beam on the top of the column. The column top horizontal tension beam, on the one hand, pulls the column tops of the columns into one body, and on the other hand, serves as a corbel connecting the inclined column and the column. When the wall-attached rod rooted horizontal beam of the roof support is installed on the column, it can be installed directly opposite to the column without reserving a bolt installation space, thereby ensuring that the column is subjected to force as the center.

[0042] The utility model also provides horizontal tension beams in columns between the upright columns, between the inclined columns, and between the upright columns and the inclined columns, so as to further ensure the overall stability and rigidity of the bracket.

[0043] The utility model embeds the embedded screws before pouring the structural concrete. After the concrete pouring is completed and reaches the designed strength, the main frame is connected with the positioning screws. The steel frame is spliced ​​by bolt connection. The construction process is simple and no welding operation is required. When the steel frame is dismantled at the later stage, the bolts and the customized steel frame can be completely dismantled, basically realizing zero-loss recycling and reuse. In addition, there is no damage to the steel frame structure when the bolts and steel frame components are removed, which greatly reduces the material cost investment.
