Description

Technical Field

[0001] This invention relates to the field of parapet wall technology, specifically to a prefabricated steel structure multifunctional parapet wall and its construction method. Background Technology

[0002] A parapet wall is a low wall surrounding the roof of a building. Its main functions, besides maintaining safety, include installing waterproof brickwork at the base to prevent water seepage into the waterproofing layer or rainwater overflowing from the roof. On accessible roofs, the parapet wall protects people and also serves a decorative purpose on the building facade; on inaccessible roofs, the parapet wall serves a decorative function and also secures the asphalt felt.

[0003] In traditional building projects, the parapet wall of the roof is mostly a concrete pouring structure. When the exterior facade of the building needs to be repaired, a suspended scaffold structure is usually suspended above the parapet wall.

[0004] However, currently, the concrete strength requirements for parapet wall construction are extremely high, and pre-embedded connectors are needed to suspend the suspended platform. Since the ends of these connectors extend beyond the outside of the parapet wall, the lever principle causes excessive localized stress on the parapet wall at the location of the connectors during suspension, easily leading to cracking and posing a significant safety hazard. Therefore, this invention proposes a prefabricated steel structure multifunctional parapet wall and its construction method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated steel structure multifunctional parapet wall and its construction method, so as to solve the problem mentioned in the background art that the parapet wall will crack due to excessive local stress when suspending the suspended basket, which poses a great safety hazard.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated steel structure multifunctional parapet wall, comprising:

[0007] The building wall has a concrete foundation parapet wall poured at the top, and a connecting steel frame is provided on the outside of the concrete foundation parapet wall. The surface edge of the connecting steel frame is provided with an installation groove.

[0008] A steel parapet wall, comprising a concrete foundation above the parapet wall, the steel parapet wall including fixed columns fixedly connected to a connecting steel frame, and a first diagonal brace fixedly installed in the middle of the fixed columns; and

[0009] A suspension bracket includes a suspension beam, which is fixed to the upper end of a fixed column. A connecting column is fixedly installed at one end and the middle of the suspension beam. The connecting column is fastened to the outside of the fixed column and fixedly connected to it. A suspension guide wheel is installed at the other end of the suspension beam.

[0010] Preferably, a plurality of connecting steel frames are provided, and the plurality of connecting steel frames are equidistantly distributed along the length direction of the parapet wall of the concrete foundation. The connecting steel frame is welded by three "C" - shaped steels to form a "C" - shaped structure with the opening facing downwards.

[0011] Preferably, a plurality of fixed columns are provided. Two fixed columns are taken as a group and fixedly connected to the two side edges of the connecting steel frame. The first diagonal brace is inclined and fixedly welded to the upper ends and the middle parts of the two fixed columns respectively.

[0012] Preferably, a plurality of suspension brackets are provided, and the plurality of suspension brackets respectively correspond to multiple groups of fixed columns. The other end of the suspension cross - beam is fixedly welded with a guide wheel bracket, and the suspension guide wheel is rotatably installed at the lower end of the guide wheel bracket.

[0013] Preferably, the other end of the suspension cross - beam is fixedly welded with an inclined reinforcing brace, and the lower end of the reinforcing brace is fixedly welded to the middle part of a connecting column.

[0014] Preferably, the fixed column, the suspension cross - beam and the connecting column are all "C" - shaped steels. Positioning holes are formed on the side of the suspension cross - beam and fixedly connected to the upper end of the connecting column through bolts.

[0015] Preferably, adjustment waist - shaped holes and connecting waist - shaped holes are respectively formed on the side of the connecting column and the side of the fixed column. The connecting column and the fixed column are fixedly connected through bolts and are located on the same straight line.

[0016] Preferably, a fixed cross - beam is arranged above the first diagonal brace. The two ends of the fixed cross - beam are respectively fixedly welded to the upper ends of the two fixed columns in the same group. Two connecting beams are welded on the upper surface of the fixed cross - beam, and the multiple fixed cross - beams are welded into a whole by the connecting beams. Second diagonal braces which are inclined and symmetrically distributed are arranged on both sides of the first diagonal brace. The upper and lower ends of the second diagonal brace are respectively welded to the fixed cross - beam and the connecting steel frame.

[0017] Preferably, a plurality of stud bolts which are equidistantly distributed are penetrated through the inner side of the connecting steel frame. Connecting nuts are arranged at the ends of the stud bolts to fixedly connect the lower half of the fixed column and the connecting steel frame. Fastening through - holes are formed at the side corners of the connecting steel frame and fixedly connected to the middle part of the fixed column through bolts. A plurality of erection steel bars which are distributed in a rectangular array are arranged inside the parapet wall of the concrete foundation, and the erection steel bars are tied and fixed to the stud bolts.

[0018] A construction method for the prefabricated steel - structure multifunctional parapet wall according to the above is specifically as follows:

[0019] Step 1: Constructing the concrete foundation parapet wall. Set up a concrete foundation parapet wall casting template at the top of the building wall, and set up multiple connecting steel frames at equal intervals along the length of the casting template. Then, pass double-headed studs through the two sides of the connecting steel frames and fix them with connecting nuts. Then, tie the reinforcing bars with thin steel wire to keep the reinforcing bars fixed to the connecting columns. Next, pour concrete grout into the casting template. After the concrete solidifies, the concrete foundation parapet wall is obtained.

[0020] Step 2: Erect the steel parapet wall. First, remove the connecting nuts from the ends of the double-ended studs. Vertically install the fixed columns on the side of the connecting steel frame and fix them with the connecting nuts. Then, install the first diagonal brace at an angle above the connecting steel frame and weld the two ends of the first diagonal brace to the two adjacent fixed columns respectively. Weld the fixed crossbeam and connecting beam to the upper end of the fixed column, and the fixed crossbeam and connecting beam are in a "well" shape. Finally, install the second diagonal brace at an angle between the two adjacent fixed crossbeams and weld the two ends of the second diagonal brace to the fixed crossbeam and connecting steel frame respectively to ensure the structural stability of the steel parapet wall.

[0021] Step 3: Erect the suspension support. The suspension support is prefabricated before hoisting. The connecting column and the suspension beam are connected by bolts, and the reinforcing brace is welded to the front end of the suspension beam. After hoisting the suspension support, the connecting column is fastened to the outside of the fixed column, and the fixed column and the connecting column are connected by bolts to complete the fixation of the suspension support.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention comprises a lower half of a concrete foundation parapet wall and an upper half of a steel structure parapet wall. A steel frame is fixedly connected to the surface of the concrete foundation parapet wall, and the steel structure parapet wall is bolted to the connecting steel frame. A suspension bracket is bolted to the upper end of the steel structure parapet wall, and the front end of the suspension bracket extends to the outside of the parapet wall and is equipped with suspension guide wheels to provide a suspended basket for suspension and lifting. This device uses a steel structure for the upper half of the parapet wall, which has higher strength. When installing the suspension bracket, it can be quickly and stably connected by bolts, which on the one hand avoids cracking of the parapet wall and reduces safety hazards, and on the other hand facilitates the disassembly of the suspension bracket.

[0035] Example 1

[0036] A prefabricated steel structure multifunctional parapet wall includes: a building wall 1, a steel structure parapet wall 5, and a suspension bracket 8.

[0037] Specifically, a concrete foundation parapet wall 2 is poured at the top of the building wall 1. A connecting steel frame 3 is set on the outside of the concrete foundation parapet wall 2. An installation groove 4 is set at the edge of the surface of the connecting steel frame 3. The connecting steel frame 3 is pre-set in the pouring template before the concrete foundation parapet wall 2 is poured. After the concrete is poured and formed, the connecting steel frame 3 can be fixed to the concrete foundation parapet wall 2.

[0038] Secondly, the steel structure parapet wall 5 is provided above the concrete foundation parapet wall 2. The steel structure parapet wall 5 includes a fixed column 6 fixedly connected to the connecting steel frame 3. A first diagonal brace 7 is fixedly installed in the middle of the fixed column 6, such as...

[0041] On the basis of Embodiment One, in order to improve the connection stability between the lower half of the fixed column 6 and the connection steel frame 3, multiple connection steel frames 3 are provided in this application, and the multiple connection steel frames 3 are equally spaced along the length direction of the parapet wall 2 of the concrete foundation. The connection steel frame 3 is made of three "C" - shaped steels welded into a "C" - shaped with the opening facing downwards. Therefore, the lower half of the fixed column 6 can be more stably connected to the side of the connection steel frame 3, thereby ensuring that the steel structure parapet wall 5 and the parapet wall 2 of the concrete foundation will not easily become loose.

[0042] Embodiment Three

[0043] On the basis of Embodiment Two, in order to prevent the steel structure parapet wall 5 from deforming after hanging the hanging basket, multiple fixed columns 6 are provided in this application. Two fixed columns 6 are taken as a group and fixedly connected to the two side edges of the connection steel frame 3. The first diagonal brace 7 is obliquely arranged and fixedly welded to the upper end and the middle of the two fixed columns 6 respectively, for strengthening the overall strength of the steel structure parapet wall 5 and preventing the steel structure parapet wall 5 from deforming under the gravity of the hanging basket after the hanging basket is hung on the upper part of the steel structure parapet wall 5 .

[0044] Embodiment Four

[0045] On the basis of Embodiment Three, in order to avoid the overall deformation of the suspension bracket 8, multiple suspension brackets 8 are provided in this application. The multiple suspension brackets 8 respectively correspond to multiple groups of fixed columns 6 one by one. A guide wheel bracket 12 is fixedly welded to the other end of the suspension crossbeam 9, and the suspension guide wheel 11 is rotatably installed at the lower end of the guide wheel bracket 12, so as to ensure that the steel wire rope of the hanging basket can be suspended outside the suspension guide wheel 11. In addition, an inclined reinforcing brace 13 is fixedly welded to the other end of the suspension crossbeam 9, and the lower end of the reinforcing brace 13 is fixedly welded to the middle of a connection column 10, for supporting the overall strength of the suspension bracket 8 and avoiding the deformation of the suspension crossbeam 9 due to excessive local stress caused by the lever principle.

[0046] Embodiment Five

[0047] Based on Embodiment 4, in order to facilitate the disassembly of the suspension bracket 8, the fixed column 6, the suspension beam 9, and the connecting column 10 of this application are all "U" shaped steel, thereby ensuring that the fixed column 6 and the connecting column 10, as well as the suspension beam 9 and the connecting column 10, can be more stably connected together. The side of the suspension beam 9 is provided with a positioning hole 14 and is fixedly connected to the upper end of the connecting column 10 with bolts. The suspension beam 9 and the connecting column 10 can also be directly welded. The side of the connecting column 10 and the side of the fixed column 6 are respectively provided with an adjustment waist hole 15 and a connection waist hole 16. The connecting column 10 and the fixed column 6 are fixedly connected by bolts and are located on the same straight line. Therefore, the entire suspension bracket 8 can be fixed to the steel structure parapet wall 5 with only bolts, which makes it easier to disassemble the suspension bracket 8.

[0048] Example 6

[0049] Based on Embodiment 5, in order to further strengthen the overall strength of the steel structure parapet wall 5, this application also includes a fixed crossbeam 17 provided above the first diagonal brace 7. The two ends of the fixed crossbeam 17 are respectively fixedly welded to the upper ends of two fixed columns 6 in the same group to strengthen the overall strength of the steel structure parapet wall 5. Two connecting beams 18 are welded to the upper surface of the fixed crossbeam 17. The connecting beams 18 weld multiple fixed crossbeams 17 into one piece, thereby connecting multiple connecting waist holes 16 into one piece. The two sides of the first diagonal brace 7 are provided with inclined and symmetrically distributed second diagonal braces 19. The upper and lower ends of the second diagonal braces 19 are respectively welded to the fixed crossbeam 17 and the connecting steel frame 3 to prevent the steel structure parapet wall 5 from tilting and deforming along the length direction of the concrete foundation parapet wall 2.

[0050] Example 7

[0051] Based on Embodiment Six, in order to strengthen the strength of the concrete foundation parapet wall 2 after casting, this application further includes multiple double-headed studs 20 evenly spaced and penetrating the inner side of the connecting steel frame 3. Each double-headed stud 20 has a connecting nut 21 at its end, which secures the lower half of the fixed column 6 to the connecting steel frame 3. A fastening through hole 22 is provided at the side corner of the connecting steel frame 3, and bolts are used to securely connect it to the middle of the fixed column 6. Multiple reinforcing bars 23 arranged in a rectangular array are provided inside the concrete foundation parapet wall 2. These reinforcing bars 23 are tied and fixed to the double-headed studs 20. Figure 3 As shown, the double-headed studs 20 and the reinforcing bars 23 are used to strengthen the overall strength of the concrete foundation parapet wall 2, ensuring that the concrete foundation parapet wall 2 has higher strength after being poured and formed. After the steel structure parapet wall 5 is installed on the upper end of the concrete foundation parapet wall 2, it is mainly supported by the connecting steel frame 3 and the double-headed studs 20 on its inner side, thereby avoiding the possibility of concrete cracking.

[0052] A construction method for a prefabricated steel structure multifunctional parapet wall, as described above, specifically includes the following steps:

[0053] Step 1: Pour concrete foundation parapet wall 2.

Then, pass double-headed studs 20 through the two sides of the connecting steel frames 3 and fix them with connecting nuts 21. Then, tie the reinforcing bars 23 with thin steel wire to keep the reinforcing bars 23 fixed to the connecting columns 10. Next, pour concrete grout into the pouring template. After the concrete solidifies, the concrete foundation parapet wall 2 is obtained.

[0054] Step 2: Erect the steel parapet wall 5. First, remove the connecting nut 21 from the end of the double-headed stud 20. Vertically install the fixed column 6 on the side of the connecting steel frame 3 and fix it with the connecting nut 21. Then, set the first diagonal brace 7 at an angle above the connecting steel frame 3 and weld the two ends of the first diagonal brace 7 to the two adjacent fixed columns 6 respectively. Weld the fixed beam 17 and the connecting beam 18 to the upper end of the fixed column 6. The fixed beam 17 and the connecting beam 18 are in a "well" shape. Finally, set the second diagonal brace 19 at an angle between the two adjacent fixed beams 17 and weld the two ends of the second diagonal brace 19 to the fixed beam 17 and the connecting steel frame 3 respectively to ensure the structural stability of the steel parapet wall 5.

[0055] Step 3: Erect the suspension bracket 8. The suspension bracket 8 is prefabricated before hoisting. The connecting column 10 and the suspension beam 9 are connected by bolts, and the reinforcing brace 13 is welded to the front end of the suspension beam 9. After hoisting the suspension bracket 8, the connecting column 10 is fastened to the outside of the fixed column 6, and the fixed column 6 and the connecting column 10 are connected by bolts to complete the fixation of the suspension bracket 8.
