Description

Technical Field

[0001] This application relates to the technical field of building structures, and particularly relates to a beam-column joint for installing saddle plates and its construction technology. Background Art

[0002] The prestressed concrete saddle-shaped shell plate (referred to as the saddle plate) is a new type of space thin-walled structure that combines a slab and a frame, used as a roof to replace the slab beam (or roof truss). In recent years, it has been widely promoted and applied in the roof structures of many building projects in the southern regions of our country, achieving good economic and technical effects.

[0003] Both ends of the saddle plate are supported by a supporting beam, and the supporting beam is connected to the column to form a beam-column joint. The traditional beam-column joints are all cast on-site at the construction site by using formwork for the column and the supporting beam. When casting, the column is first cast, and after the column is fixed, the formwork for the supporting beam is erected above the column to cast the supporting beam. The beam-column joints constructed by the above method mainly have the following problems: 1. It is necessary to move the formwork, structural steel bars, cement, sand and gravel, etc. to the construction site, which requires a large number of workers and occupies a large area of the site. Moreover, the space for reusing the wooden formwork and supporting columns after being sawn into different sizes is getting smaller and smaller, thus increasing many additional costs; 2. The cast-in-place column must wait for several days to remove the formwork for the next construction step, and the entire process from laying the formwork to removing the formwork takes a long time, so the entire construction period will be lengthened; 3. The connection strength between the independently cast column and the supporting beam in the horizontal direction is low. When the supporting beam generates horizontal vibration, it cannot be transmitted to the column in time, and it is easy to be damaged between the column and the supporting beam, and the seismic performance is poor. Summary of the Invention

[0004] In order to solve the problems in the prior art that the construction process of the existing beam-column joint for installing saddle plates is complex, the structural strength is low, and the seismic performance is poor, this application provides a beam-column joint for installing saddle plates and its construction technology.

[0005] The beam-column joint for installing saddle plates provided by this application adopts the following technical scheme: A beam-column joint for installing saddle plates, comprising: A precast column, on both sides of which symmetrically arranged corbels are provided. In the middle of the upper end surface of the corbel, a connecting column extends upward. Column embedded parts are provided on the upper end surface of the corbel and the side surface of the connecting column; A precast supporting beam, in the middle of which a gutter is provided along the length. The side walls on both sides of the gutter extend towards the two ends of the supporting beam to form connecting parts, and beam embedded parts matching with the column embedded parts are provided on the connecting parts; One end of the joist is connected to the column. The connecting part at one end of the joist is buckled on the corbels on both sides of the connecting column. The connecting column is embedded between the two connecting parts. The column embedded part is fixedly connected to the joist embedded part.

[0006] By adopting the above technical solution, during installation, first hoist and install the column, and then hoist the joist onto the column. The two ends of the joist are assumed on adjacent columns. The embedded parts on the column and the joist are cooperatively connected, so that the column and the joist are fixedly connected. The corbels on the column support the joist in the vertical direction. When the joist receives horizontal vibration, since the connecting parts at both ends of the joist are fixedly connected to the connecting column on the column, the joist will transmit the horizontal vibration to the column, thereby improving the seismic performance of the joist and enhancing the structural strength of the connection between the joist and the column.

[0007] Optionally, the column embedded part includes a first embedded steel plate provided on the upper end surface of the corbel and a second embedded steel plate provided on the side surface of the connecting column. The joist embedded part includes a fourth embedded steel plate provided on the upper and lower end surfaces of the connecting part. The fourth embedded steel plate on the upper end surface of the connecting part is welded to the second embedded steel plate, and the fourth embedded steel plate on the bottom surface of the connecting part is welded to the first embedded steel plate.

[0008] By adopting the above technical solution, when the column and the joist are connected, the fourth embedded steel plate on the joist is welded to the first embedded steel plate and the second embedded steel plate on the column. While improving the structural strength of the connection between the joist and the column, it enables the joist and the column to be in contact in the horizontal direction, thus the force transmission path. When vibration occurs, the joist can conduct the vibration to the column, improving the seismic performance at the connection between the joist and the column.

[0009] Optionally, the second embedded steel plate and the first embedded steel plate are connected to the column through a number of first strengthening anchor rods, and the fourth embedded steel plate is connected to the connecting part through a number of second strengthening anchor rods.

[0010] By adopting the above technical solution, the first strengthening anchor rods and the second strengthening anchor rods are provided to improve the structural strength of the connection between the second embedded steel plate and the first embedded steel plate and the column, and to improve the structural strength of the connection between the fourth embedded steel plate and the connecting part.

[0011] Optionally, cement mortar is poured at the connection between the column and the joist to be cured into one body.

[0012] By adopting the above technical solution, the connection between the column and the joist is poured into one body with cement mortar. The gap at the connection between the column and the joist is sealed with cement mortar, improving the waterproof performance at the connection between the column and the joist. At the same time, the column and the joist are poured into one body, enhancing the structural strength of the connection.

[0013] Optionally, the column embedded part includes third embedded steel plates arranged on both sides of the upper end face of the bracket. At least two connecting screws are arranged at one end of the third embedded steel plate away from the connecting column. A steel pipe is penetrated through the connecting column, and a tension rod is penetrated through the steel pipe. A fifth embedded steel plate is arranged on the side of the connecting part connected to the bracket and the connecting column. The fifth embedded steel plate is L-shaped, extends outwards and is provided with at least two connecting holes. The fifth embedded steel plate is fixedly connected to the connecting screw and the tension rod through the connecting holes.

[0014] By adopting the above technical solution, when the corbel is connected to the column, the connecting holes in the fifth embedded steel plate on the corbel cooperate with the connecting screws and the tension rods on the column, and then the fifth embedded steel plate is fixedly connected to the third embedded steel plate and the steel pipe on the column through nuts, realizing the fixed connection in the vertical and horizontal directions, simplifying the installation process, facilitating subsequent disassembly and assembly, and improving the structural strength at the same time.

[0015] Optionally, a number of L-shaped third strengthening anchor rods are arranged on one side of the fifth embedded steel plate connected to the connecting part.

[0016] By adopting the above technical solution, the fifth embedded steel plate is connected to the connecting part through the L-shaped third strengthening anchor rods. The L-shaped third strengthening anchor rods can realize the limit fixation in multiple directions, thereby improving the structural strength of the connection between the fifth embedded steel plate and the connecting part.

[0017] Optionally, a waterproof coating is applied to the connection between the column and the corbel.

[0018] By adopting the above technical solution, a waterproof layer is applied to the connection between the column and the corbel, improving the waterproof effect at the connection between the column and the corbel and preventing water leakage.

[0033] The following further elaborates on the present application in conjunction with the attached Figures 1-7 drawings.

[0034] Embodiment 1: Refer to Figure 1 , Figure 2 and Figure 3, a beam-column joint for saddle plate installation, comprising a column 1 and a corbel beam 2. On both sides above the column 1, brackets 11 are symmetrically arranged. In the middle of the upper end surface of the bracket 11, a connecting column 12 extending upward is provided. On the upper end surfaces of both brackets 11, first embedded steel plates 131 are arranged. The first embedded steel plates 131 are fixedly connected to the brackets 11 through first strengthening anchor bolts 133. On both side surfaces of the connecting column 12, second embedded steel plates 132 are arranged. The second embedded steel plates 132 are also fixedly connected to the connecting column 12 through multiple first strengthening anchor bolts 133. In the middle of the corbel beam 2, a gutter 23 for drainage is provided. The side walls on both sides of the gutter 23 extend towards both ends of the corbel beam 2 to form protruding connecting parts 21. On the upper and lower end surfaces of the connecting parts 21, fourth embedded steel plates 221 are arranged. The fourth embedded steel plates 221 are fixedly connected to the connecting parts 21 of the corbel beam 2 through multiple second strengthening anchor bolts 222. When the corbel beam 2 is connected to the column 1, the two connecting parts 21 on the corbel beam 2 respectively abut against the upper end surfaces of the two brackets 11 on the column 1. The connecting column 12 enters between the two connecting parts 21. The fourth embedded steel plate 221 at the bottom of the connecting part 21 is in contact connection with the first embedded steel plate 131. The fourth embedded steel plate 221 above the connecting part 21 is in contact connection with the second embedded steel plate 132. The first embedded steel plate 131 and the second embedded steel plate 132 are respectively welded to the fourth embedded steel plates 221 on the upper and lower sides of the connecting part 21. Adjacent two corbel beams 2 are arranged on the same column. The two ends of the two corbel beams 2 abut against each other. After the connection between the corbel beam 2 and the column 1 is completed, the connection between the corbel beam 2 and the column 1 is poured with cement mortar, so that the connection between the column 1 and the corbel beam 2 is poured to form a whole, improving the structural strength of the connection and realizing waterproofing at the same time.

[0035] In this embodiment, the implementation principle of a beam-column joint for saddle plate installation and its construction process is as follows: When installing the beam-column joint, first, the prefabricated column 1 is installed by hoisting, and then the corbel beam 2 is hoisted between the two columns 1. The connecting parts 21 at both ends of the corbel beam 2 are connected to the brackets 11 on the column 1. The connecting column 12 on the column 1 enters the middle of the two connecting parts 21. Then, the connection between the first embedded steel plate 131 and the fourth embedded steel plate 221 below the connecting part 21 is welded, and the connection between the second embedded steel plate 132 and the fourth embedded steel plate 221 above the connecting part 21 is welded, so that the column 1 and the corbel beam 2 are fixedly connected. When the installation of adjacent two corbel beams 2 on the same column 1 is completed, cement mortar is poured at the connection between the corbel beam 2 and the column 1. The connection between the column 1 and the corbel beam 2 is poured into a whole by using the cement mortar. After the construction is completed, the column 1 stably supports the corbel beam 2 in the vertical direction through the brackets 11 on both sides. When the corbel beam 2 generates horizontal vibration, the corbel beam 2 transmits the vibration to the connecting column 12 through the connected fourth embedded steel plate 221 and the second embedded steel plate 132, and transmits it to the column 1 through the connecting column 12, preventing the corbel beam 2 from detaching from the column 1 under the action of vibration, and improving the structural strength and seismic performance of the connection between the corbel beam 2 and the column 1.

[0036] Example 2: Referring to Figure 4 , the difference between this embodiment and Embodiment 1 is that in this embodiment, the height of the connecting portion 21 is higher than the upper surface of the connecting column 12, the fourth embedded steel plate 221 above the connecting portion 21 extends above the connecting column 12, the second embedded steel plate 132 is arranged on the upper surface of the connecting column 12, the fourth embedded steel plate 221 extends above the second embedded steel plate 132 and is in contact connection with the upper surface of the second embedded steel plate 132, the connection between the fourth embedded steel plate 221 and the second embedded steel plate 132 is welded, and the distance between the two fourth embedded steel plates 221 on both sides of the connecting column 12 is 4 - 5 cm.

[0037] Example 3: Referring to Figure 5 and Figure 6 , a beam-column joint for installing a saddle plate, comprising a column 1 and a corbel 2. On both sides above the column 1, brackets 11 are symmetrically arranged. In the middle of the upper end surface of the bracket 11, a connecting column 12 extending upward is arranged. On the upper end surfaces of both brackets 11, L-shaped third embedded steel plates 137 are arranged. A connecting screw 136 is arranged at one end of the third embedded steel plate 137 far from the connecting column 12. A steel pipe 134 is embedded in the connecting column 12, and a tension bolt 135 is arranged inside the steel pipe 134; on the outer side of the connecting portion 21 of the corbel 2, a fifth embedded steel plate 223 is arranged. The fifth embedded steel plate 223 is L-shaped and is connected to the two side surfaces of the connecting portion 21. The fifth embedded steel plate 223 is fixedly connected to the connecting portion 21 through a third reinforcing anchor bolt 224. The third reinforcing anchor bolt 224 is L-shaped and its two ends are respectively connected to both sides of the fifth embedded steel plate 223. The L-shaped third reinforcing anchor bolt 224 limits the fifth embedded steel plate 223 in multiple directions to improve the structural strength. Both ends of the fifth embedded steel plate 223 extend outward and are provided with two connecting holes 225. During installation, the bottom of the fifth embedded steel plate 223 on the connecting portion 21 is in contact connection with the third embedded steel plate 137. The connecting hole 225 at one end below the fifth embedded steel plate 223 is correspondingly sleeved on the connecting screw 136. The connecting hole 225 at one end above the fifth embedded steel plate 223 corresponds to the steel pipe 134 in the middle of the connecting column 12. After the corbel 2 and the column 1 are installed in place, a tension bolt 135 is inserted into the steel pipe. The tension bolt 135 penetrates through the connecting hole 225 at one end above the fifth embedded steel plate 223, and then the fifth embedded steel plate 223 is fixedly connected to the tension bolt 135 and the third embedded steel plate 137 through nuts, thereby fixedly connecting the column 1 and the corbel 2. After the connection is completed, a waterproof coating is provided at the joint between the column 1 and the corbel 2 to improve the waterproof performance of the joint. The above structure realizes the rapid installation of the corbel 2 and the column 1, improves the construction efficiency, and can also be disassembled for later maintenance.

[0038] Referring to Figure 7, a construction process for beam-column joints used in the installation of saddle plates, the steps of which include: 101. Prefabricate columns and corbels Use prefabricated templates to pour columns and corbels, set embedded parts on the upper end surface of the corbels of the columns and on the connecting columns, and set embedded parts on the outer side of the connecting parts of the corbels; 102.

Pour the connection between the columns and corbels into one body Use high-expansion cement mortar to grout and pour the connection between the columns and corbels to form one body. After fixing the connection between the columns and corbels, set baffles inside the gutter of the corbel, then pour cement mortar into the connection between the corbel and the column until it is flush with the upper surface of the gutter. After the cement mortar solidifies, remove the baffles, and use the cement mortar to pour the connection between the corbel and the column to form one body.

[0039] In summary, in this application, prefabricated columns and corbels are used. During installation, the columns and corbels are assembled by lifting and fixedly connected, which simplifies the installation process of beam-column joints, reduces the labor intensity of operators, improves the construction efficiency, shortens the construction period and reduces the cost; in this application, matching embedded parts are set at the connection between the columns and corbels, and connecting columns are set on the columns. The connecting columns connect the corbels through the embedded parts, and the columns and corbels are fixedly connected through the embedded parts, which improves the structural strength of the connection. By setting the connecting columns, when the corbel is subjected to horizontal vibration, the vibration can be transmitted to the column through the connecting columns, thereby preventing the corbel from separating from the column under the action of vibration, and improving the structural strength and seismic performance of the connection between the column and the corbel. Therefore, this application effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
