Description

TECHNICAL FIELD

[0001] The present application relates to the construction technology field, and in particular to a pool wall column embedded part installation construction method. BACKGROUND

[0002] There are many wall columns around the test pool of the internal structure of a test plant project. According to the design drawings, the wall column stress reinforcement is GFRP composite reinforcement, and there are a large number of stainless steel embedded parts on the wall column. The embedded part installation precision requirement is high, and the installation and precision control of the wall column embedded part must be done well during the construction process.

[0003] The traditional embedded part installation method is to rely on the pool wall reinforcement for welding and fixing, but the wall column of the project is GFRP composite reinforcement and cannot be welded. Even if it can be temporarily fixed, but due to the wall column and the pool wall reinforcement being an integral whole, whether it is formwork installation or concrete pouring, there is disturbance, and the positioning accuracy cannot be guaranteed. Based on the above reasons and the late arrival of GFRP composite reinforcement, the installation precision of the embedded part is directly restricted. The premise of ensuring the stability of the embedded part is to provide a stable and reliable point of force.

[0004] Therefore, there is an urgent need for a pool wall column embedded part installation construction method to solve the problem of low positioning precision of the embedded part when the GFRP composite reinforcement cannot be welded. SUMMARY

[0005] The present application provides a pool wall column embedded part installation construction method to solve the problem of low positioning precision of the embedded part when the GFRP composite reinforcement cannot be welded.

[0006] To achieve the above purpose, the present application adopts the following technical scheme:

[0007] A pool wall column embedded part installation construction method, characterized in that it comprises the following steps:

[0008] Step 1: During the construction of the pool wall and the foundation raft of the pool wall column, two vertical fixed angle steels are embedded according to the preset position;

[0009] Step 2: First, the structure of the pool wall is constructed, and according to the position of the two fixed angle steels, an eight-shaped opening for connecting with the pool wall column is reserved on the side wall of the pool wall;

[0010] Step 3: After the construction of the pool wall is completed, the reinforcement structure of the pool wall column is tied and completed, and according to the preset position of the several embedded parts, several transverse connecting steels are connected between the two fixed angle steels to form a support;

[0011] Step four: anchor steel bars are arranged on the side of the embedded part close to the pool wall, and several embedded parts are fixedly connected with corresponding transverse connecting steel bars by using the anchor steel bars on the embedded parts to complete the installation of the embedded parts;

[0012] Step five: then, subsequent structure construction of the pool wall column is performed.

[0013] To optimize the above technical solution, the specific measures taken also include:

[0014] Further, in step two, the one end of the eight-shaped opening reserved on the side wall of the pool wall is expanded.

[0015] Further, in step two, at least two mustache steel bars are preset on the side wall of the eight-shaped opening structure when the structure construction of the pool wall is performed, and at least two tie steel bars are correspondingly intersected and connected between the side edges of the two fixed angle steels and the mustache steel bars.

[0016] Further, in step three, after the support is formed by connecting several transverse connecting steel bars between the two fixed angle steels, one fixed steel bar is arranged at the corresponding upper and lower ends of the two fixed angle steels, and after the fixed steel bar is arranged, a steel wire rope for reference of the verticality of the embedded part is pulled between the two fixed steel bars on the same fixed angle steel.

[0017] Further, in step three, the steel bar of the pool wall column is made of GFRP.

[0018] Further, in step one, the guide wall section construction of the pool wall and the pool wall column is performed at the foundation raft construction stage of the pool wall and the pool wall column.

[0019] Further, in step four, the wall column axis is popped out on the vertical face concrete surface of the guide wall section of the pool wall column by using a line, and then the embedded part center line is set according to the transverse connecting steel bar, and the embedded part is positioned and set according to the wall column axis and the embedded part center line.

[0020] Further, in step four, the anchor steel bars arranged on the side of the embedded part close to the pool wall are provided with several anchor steel bars in the horizontal direction.

[0021] Further, in step four, when the several embedded parts are installed, the embedded parts at the upper and lower ends are installed first, and then the remaining embedded parts are sequentially arranged towards the center position.

[0022] Further, in step four, the embedded part is a steel plate, and double-sided adhesive tape for closely adhering to the wall column formwork is adhered around the steel plate.

[0023] The beneficial effects of the present application are:

[0024] The application relies on the idea of pouring the pool wall structure first and pouring the pool wall column structure later, installs the embedded part of the wall column on a relatively stable, reliable and firm structure support composed of two vertical fixed angle steels and transverse connecting steels, to meet the accurate installation requirement of the embedded part. The relatively stable, reliable and firm structure support composed of two vertical fixed angle steels and transverse connecting steels not only does not affect the pouring of the pool wall column structure, but also can increase the structural strength of the pool wall column structure as a framework, at the same time, facilitates the accurate positioning of the embedded part, and guarantees the construction efficiency and construction precision of the pool wall column structure.

DETAILED DESCRIPTION

[0030] The application will be further described in detail in combination with the drawings.

[0031] As shown in the drawings, Figure 1 The pool wall column embedded part installation construction method of the embodiment of the application includes the following steps:

[0032] Step one: in the foundation raft construction stage of the pool wall 7 and the pool wall column 1, according to the fixed angle steel 3 positioning drawing, two vertical fixed angle steels 3 are pre-embedded and inserted at the preset position, and the verticality of the fixed angle steel 3 should be ensured during pre-embedding, and the fixed angle steel 3 cannot be twisted;

[0033] Step two: the structure construction of the pool wall 7 is carried out first, and according to the position of the two fixed angle steels 3, an eight-shaped opening used for connecting with the pool wall column 1 is reserved on the side wall of the pool wall 7;

[0034] Step 3: After the construction of the pool wall 7 is completed, the reinforcement structure of the pool wall column 1 is tied. According to the preset position of several embedded parts 4, several transverse connecting steel bars 5 are welded between the two fixed angle steels 3 to form a support. 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.

[0035] Step Four: As attached Figure 2 As shown, anchoring steel bars are installed on the side of the embedded part 4 near the pool wall 7. Several embedded parts 4 are then welded and fixed to the corresponding transverse connecting steel bars 5 using the anchoring steel bars on them, so as to complete the installation of the embedded part 4.

[0036] Step 5: Then, in conjunction with the V-shaped opening reserved on the side wall of pool wall 7, the subsequent structural construction of pool wall column 1 will be carried out.

[0037] This invention relies on the idea of ​​casting the pool wall 7 structure first and the pool column 1 structure later. The embedded part 4 of the column is installed on a relatively stable, reliable and firm structural support composed of two vertical fixed angle steels 3 and horizontal connecting steel bars 5, so as to meet the precise installation requirements of the embedded part 4.

[0038] In another specific embodiment based on the above, in step two, the V-shaped opening reserved on the side wall of the pool wall 7 has an flared end located on the inner side of the pool wall 7. This V-shaped opening increases the reliability of the connection between the pool wall 7 and the pool wall column 1 structure.

[0039] In another specific embodiment based on the above, in step two, during the structural construction of the pool wall 7, at least two reinforcing bars 9 are pre-installed on the side wall of the V-shaped structure, and at least two tie bars 2 are correspondingly cross-connected between the sides of the two fixed angle steels 3 and the reinforcing bars 9. In this way, the reinforcing bars 9 and tie bars 2 are used to ensure the verticality of the fixed angle steels 3 as supports. In this embodiment, the pool wall column 1 is cast later, and the already cast pool wall 7 structure provides a reliable and stable reference surface. The embedded parts 4 are fixed using the support structure constructed with the fixed angle steels 3, effectively solving the problem that the dimensional deviation control of the high-precision embedded parts 4 is affected by construction disturbances.

[0040] 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 support, a fixed steel bar 14 is set at the upper and lower ends of the two fixed angle steels 3 respectively. After the fixed steel bar 14 is set, a steel wire rope 15 is pulled between the two fixed steel bars 14 on the same fixed angle steel 3 for the embedded part 4 to refer to the verticality.

[0041] In another specific embodiment based on the above, in step three, the reinforcing material of the pool wall column 1 is GFRP bars 6.

[0042] In another specific embodiment based on the above, in step one, during the construction of the pool wall 7 and the foundation raft of the pool wall column 1, the guide wall section 13 of the pool wall 7 and the pool wall column 1 is constructed. Further, in step four, the wall column axis 11 is popped out on the fair face concrete surface of the guide wall section 13 of the pool wall column 1 with a line marker, and then the embedded part center line 12 is set according to the transverse connecting steel bars 5, and the embedded part 4 is positioned and set according to the wall column axis 11 and the embedded part center line 12.

[0043] In another specific embodiment based on the above, in step four, the anchor steel bars set on the side of the embedded part 4 close to the pool wall 7 are several in number and arranged in the horizontal direction. In this way, the connection and positioning of the embedded part 4 are facilitated by the several anchor steel bars arranged in the horizontal direction.

[0044] As shown in the accompanying drawings, Figure 3 In another specific embodiment based on the above, in step four, when several embedded parts 4 are installed, the embedded parts 4 at the upper and lower ends are installed first, and then the remaining embedded parts 4 are sequentially set towards the center position one by one. In this way, the remaining embedded parts 4 can be sequentially set towards the center position one by one with the aid of positioning by the two end embedded parts 4 installed first.

[0045] In another specific embodiment based on the above, in step four, the embedded part 4 is a steel plate, and double-sided adhesive tape for tightly adhering to the wall column formwork is pasted around the steel plate. In this way, the steel plate as the embedded part 4 is tightly adhered to the wall column formwork by the double-sided adhesive tape, preventing the concrete from adhering to the surface of the steel plate during the wall column concrete pouring process.

[0046] One specific embodiment of the present application is as follows:

[0047] The two L63 fixed angle steels 3 are pre-buried according to the position of the positioning drawing during the reinforcement insertion in the foundation raft construction stage of the pool wall column 1, and during the construction of the pool wall 7 and the guide wall section 13 of the pool wall column 1. The pool wall 7 is constructed with a reserved eight-character opening, and the pool wall column 1 is constructed afterwards. The pool wall 7 is preferably constructed 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 bound, and the pool wall column axis 11 is popped out on the concrete surface of the guide wall section 13. After the GFRP bars 6 are bound, the two fixed angle steels 3 are welded and connected as a support using the transverse connecting steel bars 5 according to the position of the anchor steel bars on the pre-buried part 4. To ensure the verticality of the support, two φ20mm tie steel bars 2 are cross-welded with the reserved mustache steel bars 9 in the pool wall 7, and the distance between the tie steel bars 2 is not greater than 2 meters. The pre-buried part 4 is welded and fixed to the corresponding transverse connecting steel bars 5 of the support according to the anchor steel bars thereon. In each pouring section 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 fixed steel bar 14 is welded, a φ0.5mm steel wire rope 15 is pulled to control the verticality of the pre-buried part 4. The steel wire rope 15 must be taut, firmly fixed at both ends, and the distance between the steel wire rope 15 and the installation completion surface of the pre-buried part 4 is 200mm. During installation, the verticality of the pre-buried part 4 is checked by referring to the pool wall column axis 11 and relying on the steel wire rope 15, and several pre-buried parts 4 are installed from both ends to the middle. Further, during installation, the pre-buried part 4 can be temporarily fixed by inserting the anchor steel bars according to the position of the pool wall column axis 11 and the pre-buried part center line 12, to ensure that the pool wall column axis 11 coincides with the pre-buried part axis. During installation, the verticality of the pre-buried part 4 can be measured by relying on the steel wire rope 15 using a steel tape, and after final checking is completed, it can be fixed firmly.

[0048] In this scheme, the pre-buried part 4 of the pool wall column 1 is installed as much as possible according to the negative deviation control, and the deviation should not be greater than -3mm. After the pre-buried part 4 of the pool wall column 1 is installed, the verticality, elevation and plane position are checked in time, and after meeting the design requirements, it can be fixed firmly. The anchor steel bars of the pre-buried part 4 and the transverse connecting steel bars 5 are welded and fixed according to double fillet welds, and the weld height hf = 6mm. Before the pool wall column formwork is installed, double-sided adhesive tape can be pasted around each pre-buried part 4 to avoid the problem of concrete floating slurry covering the surface of the pre-buried part, causing waste of labor due to secondary polishing. During the concrete pouring process of the pool wall column 1, it must be poured in layers and the vibration is strengthened. The vibrating rod must avoid the pre-buried part 4 and the tie steel bars 2 during vibration to prevent the pre-buried part 4 from being deviated due to vibration.

[0049] After the GFRP bars 6 of the pool wall column 1 are tied, pouring is performed in sections, and a fixed steel bar 14 is welded to the upper and lower ends of the angle steel 3 in each pouring section to pull the steel wire rope 15.

[0050] In the present scheme, the installation precision of the embedded part 4 is well solved by reserving the pool wall column 1 for post-pouring and embedding the support composed of the angle steel 3 in the pool wall column 1 to fix the stainless steel embedded part 4.
