Description

Technical Field

[0001] The invention relates to the technical field of building engineering construction, and in particular to a method for installing and constructing a pre-embedded part of a pool wall column. Background Art

[0002] There are many pilasters around the test water pool of the internal structure of a certain test plant project. According to the design drawings, the stress-bearing steel bars of the pilasters are all GFRP composite bars, and there are a large number of stainless steel embedded parts on the pilasters. The installation accuracy of the embedded parts is required to be high. The installation and accuracy control of the pilaster embedded parts must be done well during the civil construction process.

[0003] The traditional method of installing embedded parts relies on welding and fixing the pool wall reinforcement, but the wall columns of this project are GFRP composite bars that cannot be welded. Even if they can be temporarily fixed, since the wall columns and the pool wall reinforcement are a whole, there will be disturbances in both template installation and concrete pouring, and accurate positioning cannot be guaranteed. Based on the above reasons and factors such as the late arrival of GFRP composite bars, the installation accuracy of embedded parts is directly restricted. The premise for ensuring the stability of embedded parts is to provide a stable and reliable point of force.

[0004] Therefore, there is an urgent need for an installation and construction method for embedded parts of pool wall columns to solve the problem of low positioning accuracy of embedded parts when GFRP composite reinforcement cannot be welded. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a method for installing and constructing a pre-embedded part of a pool wall column, so as to solve the problem that the positioning accuracy of the pre-embedded part is low when GFRP composite reinforcement cannot be welded.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A method for installing and constructing a pre-embedded part of a pool wall column, characterized in that it comprises the following steps: Step 1: During the construction phase of the foundation raft of the pool wall and the pool wall column, two vertical fixed angle steels are pre-buried and inserted according to the preset positions; Step 2: First, carry out the structural construction of the pool wall, and according to the positions of the two fixed angle steels, reserve a vertical splayed opening on the side wall of the pool wall for connection with the pool wall column; Step 3: After the pool wall construction is completed, the reinforcement structure of the pool wall column is tied, and according to the preset positions of several embedded parts, several transverse connecting steel bars are connected between two fixed angle steels to form a bracket; Step 4: Anchor steel bars are arranged on the side of the embedded parts close to the pool wall, and several embedded parts are fixedly connected with the corresponding transverse connecting steel bars by using the anchor steel bars thereon to complete the installation of the embedded parts; Step 5: After that, the subsequent structural construction of the pool wall columns will be carried out.

[0007] To optimize the above technical solutions, the specific measures taken also include: Furthermore, in step 2, the eight-shaped opening reserved on the side wall of the pool wall has an expanded opening at one end located on the inner side of the pool wall.

[0008] Furthermore, in step 2, when carrying out the structural construction of the pool wall, at least two beard steel bars are preset on the side wall of the eight-shaped structure, and at least two tie steel bars are cross-connected between the side edges of the two fixed angle steels and the beard steel bars.

[0009] Furthermore, in step three, after connecting several transverse connecting steel bars between two fixed angle steels to form a bracket, a fixed steel bar is respectively set at the upper and lower ends corresponding to the two fixed angle steels. After the fixed steel bars are set, a steel wire rope is pulled between the two fixed steel bars on the same fixed angle steel for reference of verticality of the embedded parts.

[0010] Furthermore, in step three, GFRP bars are used as reinforcement materials for the pool wall columns.

[0011] Furthermore, in step one, during the foundation raft construction stage of the pool wall and the pool wall columns, the guide wall section of the pool wall and the pool wall columns is constructed.

[0012] Furthermore, in step four, the axis of the pilaster is popped out with an ink line on the front facade concrete surface of the guide wall section of the pool pilaster, and then the center line of the embedded part is set according to the transverse connecting steel bars, and the embedded parts are positioned and set according to the axis of the pilaster and the center line of the embedded part.

[0013] Furthermore, in step four, several anchoring steel bars are arranged in the horizontal direction on one side of the embedded part close to the pool wall.

[0014] Furthermore, in step 4, when installing several embedded parts, the embedded parts at the upper and lower ends are installed first, and then the remaining embedded parts are arranged one by one toward the center.

[0015] Furthermore, in step four, the embedded part is a steel plate, and double-sided tape is pasted around the steel plate for tightly fitting with the pilaster formwork.

[0016] The beneficial effects of the present invention are: The present invention relies on the idea of ​​first casting the pool wall structure and then casting the pool pilaster structure, and installs the embedded parts of the pilaster on a relatively stable, reliable and firm structural support composed of two vertical fixed angle steels and transverse connecting steel bars, etc., to meet the precise installation requirements of the embedded parts. Among them, the relatively stable, reliable and firm structural support composed of two vertical fixed angle steels and transverse connecting steel bars, etc., not only does not affect the casting of the pool pilaster structure, but can also serve as a skeleton to increase the structural strength of the pool pilaster structure. At the same time, it is convenient for the precise positioning of the embedded parts, ensuring the construction efficiency and construction accuracy of the pool pilaster structure.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] As attached Figure 1 As shown, a method for installing and constructing a pre-embedded part of a pool wall column according to an embodiment of the present invention comprises the following steps: Step 1: During the construction stage of the foundation raft of the pool wall 7 and the pool wall column 1, two vertical fixed angle steels 3 are pre-embedded and inserted according to the preset positions of the fixed angle steel 3 positioning drawings. The verticality of the fixed angle steel 3 should be ensured during the pre-embedding, and it cannot be twisted; Step 2: First, the structure of the pool wall 7 is constructed, and according to the positions of the two fixed angle steels 3, a vertical splayed opening for connection with the pool wall column 1 is reserved on the side wall of the pool wall 7; Step 3: After the construction of the pool wall 7 is completed, the reinforcement structure of the pool wall column 1 is tied, and according to the preset positions of the embedded parts 4, several transverse connecting steel bars 5 are welded and connected between the two fixed angle steels 3 to form a bracket, and according to the relative position and number of rows of anchor steel bars on the subsequent embedded parts 4, the transverse connecting steel bars 5 between the two fixed angle steels 3 are welded; Step 4: As attached Figure 2 As shown, anchoring steel bars are arranged on one side of the embedded part 4 close to the pool wall 7, and several embedded parts 4 are respectively connected by welding with corresponding transverse connecting steel bars 5 using the anchoring steel bars thereon to complete the installation of the embedded parts 4; Step 5: After that, the subsequent structural construction of the pool wall column 1 is carried out in coordination with the reserved eight-shaped openings on the side walls of the pool wall 7.

[0021] The present invention relies on the idea of ​​first casting the pool wall 7 structure and then casting the pool pilaster 1 structure, and installs the embedded parts 4 of the pilaster on a relatively stable, reliable and firm structural support composed of two vertical fixed angle steels 3 and transverse connecting steel bars 5 to meet the precise installation requirements of the embedded parts 4.

[0022] In another specific embodiment based on the above, in step 2, the splayed opening reserved on the side wall of the pool wall 7 has an expanded opening at one end located inside the pool wall 7. In this way, the reliability of the connection between the pool wall 7 and the pool wall column 1 structure can be increased through the splayed opening.

[0023] In another specific embodiment based on the above, in step 2, when the structure of the pool wall 7 is being constructed, at least two beard steel bars 9 are preset on the side wall of the eight-shaped structure, and at least two tie steel bars 2 are cross-connected between the sides of the two fixed angle steels 3 and the beard steel bars 9. In this way, the beard steel bars 9 and the tie steel bars 2 are used to ensure the verticality of the fixed angle steels 3 as brackets. In this embodiment, the pool wall column 1 is post-cast, and the cast pool wall 7 structure is relied on to provide a reliable and stable reference surface, and the bracket constructed with the fixed angle steels 3 and other structures is used to fix the embedded parts 4, which effectively solves the problem that the installation size deviation control of the high-precision embedded parts 4 will be affected by the construction disturbance.

[0024] As attached Figure 4 As shown, in another specific embodiment based on the above, in step three, after connecting several transverse connecting steel bars 5 between two fixed angle steels 3 to form a bracket, a fixed steel bar 14 is respectively set at the upper and lower ends corresponding to the two fixed angle steels 3. After the fixed steel bar 14 is set, a steel wire rope 15 is stretched between the two fixed steel bars 14 on the same fixed angle steel 3 for reference of verticality of the embedded part 4.

[0025] In another specific embodiment based on the above, in step three, the reinforcement material of the pool wall column 1 is GFRP reinforcement 6.

[0026] In another specific embodiment based on the above, in step 1, during the foundation raft construction stage of the pool wall 7 and the pool pilaster 1, the guide wall section 13 of the pool wall 7 and the pool pilaster 1 is constructed. Further, in step 4, the pilaster axis 11 is popped out with an ink line on the front facade concrete surface of the guide wall section 13 of the pool pilaster 1, and then the embedded part center line 12 is set according to the transverse connecting steel bar 5, and the embedded part 4 is positioned and set according to the pilaster axis 11 and the embedded part center line 12.

[0027] In another specific embodiment based on the above, in step 4, several anchoring steel bars are arranged in the horizontal direction on the side of the embedded part 4 close to the pool wall 7. In this way, the connection and positioning of the embedded part 4 are facilitated by the several anchoring steel bars arranged in the horizontal direction.

[0028] As attached Figure 3 As shown, in another specific embodiment based on the above, in step 4, when installing several embedded parts 4, the embedded parts 4 at the upper and lower ends are installed first, and then the remaining embedded parts 4 are arranged one by one toward the center. In this way, the embedded parts 4 at the two ends installed first can assist in positioning, so that the remaining embedded parts 4 can be arranged one by one toward the center.

[0029] In another specific embodiment based on the above, in step 4, the embedded part 4 is a steel plate, and double-sided tape for tightly fitting with the pilaster template is pasted around the steel plate. In this way, the steel plate as the embedded part 4 is tightly fitted with the pilaster template by the double-sided tape, preventing the concrete from sticking to the steel plate surface during the pilaster concrete pouring process.

[0030] A specific implementation of the present invention is as follows: When the pool wall column 1 is inserted with reinforcement during the foundation raft construction stage, two L63 fixed angle steels 3 should be pre-buried according to the location of the positioning drawing during the construction of the pool wall 7 and the guide wall section 13 of the pool wall column 1. The length of the fixed angle steel 3 is 6 meters. When the pool wall 7 structure is constructed, the eight-shaped mouth is reserved, and the pool wall column 1 is constructed later. When pouring the pool wall 7, it is advisable to construct in sections, and the maximum pouring height should not exceed 5 meters. After the first section of the pool wall 7 structure is poured, the GFRP bars 6 of the pool wall column 1 can be tied, and the wall column axis 11 is popped up on the concrete surface of the guide wall section 13. After the GFRP bars 6 are tied, the two fixed angle steels 3 are welded and connected into a bracket using transverse connecting steel bars 5 according to the position of the anchor steel bars on the embedded parts 4. In order to ensure the verticality of the bracket, two φ20mm tie steel bars 2 are used to cross and weld with the beard steel bars 9 reserved in the pool wall 7. The spacing between the tie steel bars 2 is not more than 2 meters. The embedded part 4 is welded and fixed according to the anchoring steel bar on it and the corresponding transverse connecting steel bar 5 of the bracket. In each casting section height of the pool wall column 1, a 300mm long φ20mm fixed steel bar 14 is welded to the upper and lower ends of the fixed angle steel 3, and after the welding of the fixed steel bar 14 is completed, a φ0.5mm steel wire rope 15 is pulled to control the verticality of the embedded part 4. The steel wire rope 15 must be tightened, and both ends are firmly fixed. The distance between the steel wire rope 15 and the installation completion surface of the embedded part 4 is 200mm. During installation, refer to the wall column axis 11 and rely on the wire rope 15 to check the verticality of the embedded parts 4, and install several embedded parts 4 from both ends to the middle; further, during installation, the embedded parts 4 can be temporarily fixed by pre-insertion according to the position of the wall column axis 11 and the embedded part center line 12, ensuring that the wall column axis 11 coincides with the embedded part axis. During the installation process, a steel tape measure can be used to rely on the wire rope 15 to measure the verticality of the embedded parts 4, and they can be firmly fixed only after the final verification is completed.

[0031] In this solution, when installing the full-height embedded parts 4 of the pool wall column 1, it is controlled as much as possible according to the negative deviation, and the deviation should not be greater than -3mm. After the embedded parts 4 of the pool wall column 1 are installed, the verticality, elevation and plane position must be checked in time. They can be firmly fixed only after meeting the design requirements. The anchor steel bars of the embedded parts 4 and the transverse connecting steel bars 5 are welded and fixed according to double-sided fillet welds, and the weld height hf=6mm. Before installing the wall column formwork, double-sided tape can be pasted around each embedded part 4 to avoid the problem of concrete slurry covering the surface of the embedded parts, causing secondary grinding and wasting labor. During the pouring of the concrete of the pool wall column 1, it must be poured in layers and vibrated. During the vibration, the vibrating rod must avoid the embedded parts 4 and the tie steel bars 2 to prevent the embedded parts 4 from being displaced due to the influence of vibration.

[0032] After the GFRP bars 6 of the above-mentioned pool wall column 1 are tied, they can be poured in sections. In each pouring section height, a fixed steel bar 14 is welded to the upper and lower ends of the fixed angle steel 3 respectively for pulling the steel wire rope 15.

[0033] In this solution, the problem of installation accuracy of the embedded parts 4 can be well solved by reserving the pool wall column 1 before pouring and embedding a bracket consisting of a fixed angle steel 3 in the pool wall column 1 to fix the stainless steel embedded parts 4.
