Description

Technical Field

[0001] This invention belongs to the field of pipe sandwich technology, and specifically relates to a construction method and structure of electromechanical pipe sandwich without formwork removal. Background Technology

[0002] The investigation revealed that in many cases, there are mechanical and electrical pipe layers within reinforced concrete floor slabs. This is especially true above basement ceilings, where there are often narrow and long pipe layers.

[0003] The conventional construction method for these pipe mezzanines is as follows: first, the floor slab is constructed; then, the formwork for the pipe mezzanine side walls and top slab is erected (the formwork for the pipe mezzanine side walls and top slab forms a U-shaped mezzanine cavity); next, the reinforcement for the pipe mezzanine side walls and top slab is constructed, and concrete is poured. After the mezzanine structure is completed, construction workers enter the pipe mezzanine through manholes or pre-reserved openings to remove the inner formwork and its frame. Then, mechanical and electrical workers transport the pipes and their support materials through manholes or pre-reserved openings to install the pipes within the mezzanine. This construction method requires workers to repeatedly enter and exit the mezzanine space to move construction materials, erect pipes and supports, etc., resulting in low construction efficiency. The narrow mezzanine space leads to a harsh construction environment, restricting construction methods, prolonging the construction period, and causing considerable inconvenience. Moreover, leftover materials or waste after construction are often left in the mezzanine due to the limited space and difficulty in transportation, causing inconvenience to maintenance personnel later. Therefore, we propose a formwork-free construction method and structure for mechanical and electrical pipe mezzanines to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a construction method and structure for an electromechanical pipeline interlayer that does not require formwork removal, thus solving the problems of limited space and low construction efficiency.

[0005] This invention is achieved through the following scheme: a construction method for an electromechanical piping interlayer that does not require formwork removal, comprising the following steps: S1. Provide multiple U-shaped mezzanine templates and multiple pipe supports, and fix the multiple pipe supports into the multiple mezzanine templates respectively; S2. Provide the electromechanical piping to be installed, divide the electromechanical piping into pipe sections corresponding to multiple pipe supports, and install the multiple pipe sections on the corresponding pipe supports; S3. After the floor slab is constructed, hoist multiple mezzanine formworks to the location of the pipe mezzanine on the floor slab where construction is to be carried out, fix the multiple mezzanine formworks with the openings facing downwards, arrange the multiple mezzanine formworks along the entire length of the pipe mezzanine, and seal and fix each pair of adjacent mezzanine formworks. S4. Construct steel bars and concrete on the outside of all mezzanine formwork to form a mezzanine structure, and anchor the formed mezzanine structure to the floor slab and multiple mezzanine formwork as a whole. S5. Connect any two adjacent pipe segments.

[0006] A further improvement of the construction method of the electromechanical pipe interlayer without formwork removal of the present invention is that, when constructing the floor slab, a bearing wall is constructed on both sides of the location to be constructed of the pipe interlayer on the floor slab, and the bearing wall extends along the length of the pipe interlayer. When constructing the two supporting walls, slots are reserved at the top of both supporting walls, and when multiple mezzanine formworks are hoisted to the pipe mezzanine construction position on the floor slab, the two vertical sections of the mezzanine formwork are respectively inserted into the slots on the two supporting walls.

[0007] A further improvement of the construction method of the electromechanical pipeline interlayer without formwork removal of the present invention is that a reserved reinforcement bar located on the outside of the interlayer formwork is fixedly connected to the top of the receiving wall. During the construction of the sandwich structure, the pre-reserved reinforcement bars are wrapped and anchored in the formed sandwich structure.

[0008] A further improvement of the construction method of the electromechanical pipeline interlayer without demolding of the present invention is that each of the interlayer templates is fixedly connected to the outside of the template with a reinforcement component for reinforcing the interlayer template. When performing step S1, multiple reinforcement members are provided and fixed to the outside of multiple sandwich templates respectively. During the construction of the sandwich structure, the formed sandwich structure wraps and anchors the multiple reinforcement members.

[0009] A further improvement of the construction method of the electromechanical pipeline interlayer without formwork removal of the present invention is that when the two vertical sections of the interlayer formwork are respectively inserted into the slots on the two supporting walls, the bottom of the reinforcement is placed on the top of the supporting wall.

[0010] A further improvement of the construction method of the electromechanical pipe interlayer without demolding of the present invention is that each pipe support is fixedly fitted with a U-shaped integrated box with the opening facing downward, a slide rail is fixedly connected to the inner top wall of the interlayer template and the slide rail extends along the length direction of the interlayer template, and a slider is fixedly connected to the top of the integrated box and slidably connected to the slide rail. When fixing the pipe support inside the sandwich template, first slide the slider along the slide rail so that the pipe support slides into the corresponding sandwich template, and then fix the slider to the slide rail.

[0011] An electromechanical piping sandwich structure, formed using the construction method described above, the electromechanical piping sandwich structure comprising: Multiple U-shaped interlayer templates are fixed to the pipe interlayer on the floor slab at the location to be constructed, with their openings facing downwards. The multiple interlayer templates are arranged along the entire length of the pipe interlayer, and each pair of adjacent interlayer templates is sealed and fixed. Multiple pipe supports are fixed within multiple interlayer templates; Multiple pipe sections are installed on multiple pipe supports, and each pair of adjacent pipe sections is connected; and The mezzanine structure is formed by constructing steel bars and concrete on the outside of all the mezzanine formwork, and the resulting mezzanine structure is anchored to the floor slab and multiple mezzanine formwork as a whole.

[0012] A further improvement of the electromechanical pipe sandwich structure of the present invention is that a support wall is fixedly connected to the top of the floor slab and to both sides of the pipe sandwich construction position. The support wall extends along the length of the pipe sandwich, and the top of the two support walls is provided with slots for inserting two vertical sections of the sandwich template.

[0013] A further improvement of the electromechanical pipeline sandwich structure of the present invention is that a reserved reinforcement bar located outside the sandwich template is fixedly connected to the top of the receiving wall, and the sandwich structure wraps and anchors the reserved reinforcement bar.

[0014] A further improvement of the electromechanical pipe sandwich structure of the present invention is that each sandwich template is fixedly connected to a reinforcement member for reinforcing the sandwich template, and the reinforcement member is anchored inside the sandwich structure. Compared with the prior art, the beneficial effects of the present invention are as follows: This invention involves prefabricating interlayer templates and pipe supports, pre-installing electromechanical pipes, then installing the interlayer templates using a segmented hoisting method, and finally constructing the interlayer structure. This novel construction method avoids the problem of workers repeatedly entering and exiting the narrow interlayer space for construction, making construction not only convenient but also improving efficiency.

[0022] To address the problems of limited space and low construction efficiency, this invention provides a construction method and structure for a formwork-free electromechanical piping interlayer. The following detailed description, in conjunction with accompanying drawings, further illustrates this formwork-free electromechanical piping interlayer construction method and structure.

[0023] See Figures 1-6 As shown, a construction method for a formwork-free electromechanical piping interlayer includes the following steps: S1. Provide multiple U-shaped interlayer templates 4 and multiple pipe supports 5, and fix the multiple pipe supports 5 into the multiple interlayer templates 4 respectively; S2. Provide the electromechanical piping to be installed, divide the electromechanical piping into pipe segments 6 corresponding to multiple pipe supports 5, and install the multiple pipe segments 6 on the corresponding pipe supports 5. S3. After the floor slab 1 is completed, hoist multiple mezzanine templates 4 to the location of the pipe mezzanine to be constructed on the floor slab 1, fix the multiple mezzanine templates 4 with the opening facing downwards, arrange the multiple mezzanine templates 4 along the length of the pipe mezzanine, and seal and fix each two adjacent mezzanine templates 4. S4. Construct steel bars and concrete on the outside of all mezzanine formwork 4 to form mezzanine structure 7, and anchor the formed mezzanine structure 7 to the floor slab 1 and multiple mezzanine formwork 4 into a whole. S5. Connect any two adjacent pipe segments 6.

[0024] By prefabricating the mezzanine template 4 and pipe supports 5, and installing the electromechanical pipes in advance, the mezzanine template 4 is installed in a segmented hoisting manner, and finally the mezzanine structure 7 is constructed, the construction of the electromechanical pipe mezzanine can be completed. The new construction method avoids the problem of workers repeatedly entering and exiting the narrow mezzanine space for construction, which not only makes construction convenient but also improves construction efficiency.

[0025] Among them, see Figure 2As shown, when constructing floor slab 1, support walls 2 are constructed on both sides of the pipe interlayer to be constructed on floor slab 1, and the support walls 2 extend along the length of the pipe interlayer. When constructing the two supporting walls 2, slots 10 are reserved at the top of both supporting walls 2. When hoisting multiple interlayer templates 4 to the pipe interlayer on the floor slab 1 to be constructed, the two vertical sections of the interlayer templates 4 are respectively inserted into the slots 10 on the two supporting walls 2.

[0026] By adopting the above design, the lower end of the vertical section of the mezzanine template 4 can be inserted into the slot 10, which not only provides support for the mezzanine template 4, but also accurately determines the installation position of the mezzanine template 4, so as to facilitate hoisting and installation work.

[0027] Among them, the top of the receiving wall 2 is fixedly connected with a reserved reinforcement bar 8 located on the outside of the mezzanine formwork 4; During the construction of the mezzanine structure 7, the formed mezzanine structure 7 is used to wrap and anchor the reserved reinforcement 8.

[0028] By adopting the above design, the reserved reinforcement 8 can serve as a connector between the support wall 2 and the mezzanine structure 7, thereby strengthening the connection between the two.

[0029] Among them, see Figure 3 , Figure 5 as well as Figure 6 As shown, each sandwich template 4 is fixedly connected to a reinforcement member 9 for reinforcing the sandwich template 4. When performing step S1, multiple reinforcing members 9 are provided and fixed to the outside of multiple interlayer templates 4 respectively. When constructing the interlayer structure 7, the formed interlayer structure 7 encloses and anchors the multiple reinforcing members 9.

[0030] Further, see Figure 6As shown, each reinforcing member 9 includes two sets of side sections 901, multiple top sections 902, and two sets of connecting sections 903. The two sets of side sections 901 are fixedly connected to the two sides of the corresponding interlayer template 4. Each set of side sections 901 includes multiple side sections 901, which are arranged along the length of the interlayer template 4. The multiple side sections 901 in the two sets of side sections 901 correspond one-to-one. The multiple top sections 902 are fixed to the top of the interlayer template 4, and are arranged along the length of the interlayer template 4. The number of segments 902 is consistent with the number of side segments 901 in each group of side segments 901 and is set accordingly. Both ends of each top segment 902 are respectively connected and fixed to two corresponding side segments 901. Two groups of connecting segments 903 are respectively fixedly connected to both sides of the interlayer template 4. Each group of connecting segments 903 includes multiple connecting segments 903, and the multiple connecting segments 903 are arranged along the height direction of the interlayer template 4. Each connecting segment 903 located on the same side of the interlayer template 4 is connected and fixed to all side segments 901 on the same side. By adopting the above design, the overall strength of the sandwich template 4 can be greatly improved by using the reinforcement 9. It can play a better supporting role when constructing the sandwich structure 7, and can also serve as a skeleton to improve the overall strength of the sandwich structure 7.

[0031] Among them, see Figure 2 , Figure 5 as well as Figure 6 As shown, when the two vertical sections of the interlayer template 4 are inserted into the slots 10 on the two supporting walls 2 respectively, the bottom of the reinforcement 9 rests on the top of the supporting wall 2.

[0032] Furthermore, the depth of the slot 10 is a, and the distance between the bottom connecting segment 903 and the bottom of the sandwich structure is also a. Therefore, when the two vertical segments of the sandwich template 4 are inserted into the slots 10 on the two supporting walls 2 respectively, the bottom connecting segment 903 in the reinforcement 9 will rest on the top of the supporting wall 2. By adopting the above design, the connection section 903 contacts the top of the receiving wall 2, which can serve as a secondary support for the mezzanine formwork 4, facilitating the subsequent construction of the mezzanine structure 7.

[0033] Among them, see Figure 3-5 As shown, each pipe support 5 is fixedly fitted with a U-shaped integrated box 13 with the opening facing downward. A slide rail 11 is fixedly connected to the inner top wall of the interlayer template 4, and the slide rail 11 extends along the length direction of the interlayer template 4. A slider 12 is fixedly connected to the top of the integrated box 13 and is slidably connected to the slide rail 11. When fixing the pipe support 5 into the interlayer template 4, first slide the slider 12 along the slide rail 11 so that the pipe support 5 slides into the corresponding interlayer template 4, and then fix the slider 12 to the slide rail 11.

[0034] By adopting the above design, the installation of the integrated box 13 and the interlayer template 4 can be made more convenient by using the cooperation of the slide rail 11 and the slider 12. Furthermore, by fixing the two together, the pipe support 5 can be suspended above the pipe interlayer cavity 3, and the height of the lower space left is h, which facilitates subsequent maintenance by workers. The width of the formed pipe interlayer cavity 3 is d.

[0035] An electromechanical piping sandwich structure, formed using the construction method described above, comprises: Multiple U-shaped interlayer templates 4 are fixed to the pipe interlayer on the floor slab 1 with their openings facing downwards, so that multiple interlayer templates 4 are arranged along the entire length of the pipe interlayer, and each pair of adjacent interlayer templates 4 are sealed and fixed. Multiple pipe supports 5 are fixed inside multiple interlayer templates 4 respectively; Multiple pipe segments 6 are installed on multiple pipe supports 5, and every two adjacent pipe segments 6 are connected; and The mezzanine structure 7 is formed by constructing steel bars and concrete on the outside of all the mezzanine formwork 4, and the formed mezzanine structure 7 is anchored to the floor slab 1 and multiple mezzanine formwork 4 as a whole.

[0036] Among them, the top of the floor slab 1 and both sides of the pipe interlayer to be constructed are fixedly connected to the support wall 2. The support wall 2 extends along the length of the pipe interlayer. The top of the two support walls 2 is provided with slots 10 for the two vertical sections of the interlayer template 4 to be inserted respectively.

[0037] Among them, the top of the receiving wall 2 is fixedly connected with a reserved reinforcement bar 8 located outside the mezzanine template 4, and the mezzanine structure 7 wraps and anchors the reserved reinforcement bar 8.

[0038] Each sandwich template 4 is fixedly connected to a reinforcement member 9 for reinforcing the sandwich template 4, and the reinforcement member 9 is anchored inside the sandwich structure 7.
