Description

Technical Field

[0001] The present application belongs to the field of building construction technology, and in particular relates to a construction method for walls at gaps. Background Art

[0002] In the process of building construction, expansion joints or seismic joints are inevitable. When aluminum alloy formwork is used for construction, this part cannot be assembled, and the lower opening of the formwork at the inner wall of the expansion joint is not tightly sealed, resulting in serious leakage during concrete pouring. At present, this position mainly uses a whole large steel plate or wooden formwork for matching, and fills the expansion joint or seismic joint with extruded board. However, this method of using a whole large steel plate or wooden formwork for matching the inner formwork of the double wall of the expansion joint or seismic joint is prone to expansion or running of the formwork due to the poor combination of the large steel plate and wooden formwork with the aluminum alloy formwork. In addition, when using this method, it is difficult to seal the gap at the lower opening of the inner formwork at the double wall of the expansion joint, which is particularly prone to leakage. Summary of the invention

[0056] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] This embodiment provides a construction method for a wall at a gap, such as Figure 1As shown, the steps include:

[0058] S1. Prepare an integrated module 40 on one side of the wall 10 to be built close to the gap 30.

[0059] One side of the wall 10 to be built is a fixed wall 70 that has been built, and the gap 30 between it and the fixed wall 70 is an unconventional gap distance, such as an expansion joint or an earthquake-resistant joint; and below the wall 10 to be built is the completed built wall 20, the wall 10 to be built is located at the corner of the built wall 20, and is directly connected to the vertical section of the built wall 20 at both ends, and is located on the horizontal section of the built wall 20.

[0060] like Figure 2-3 As shown in Figures 7 and 8, when manufacturing the integrated module 40, it is required that the overall height H of the integrated module 40 is greater than the sum of the height h1 of the wall 10 to be built and the thickness h2 of the horizontal section of the built wall 20, and the lower end surface of the integrated module 40 is fixed on the vertical section of the built wall 20, thereby ensuring that the outer side of the wall 10 to be built is enclosed in a sealed pouring cavity to prevent leakage during pouring; at the same time, the setting of the integrated module 40 can also prevent the problem of mold expansion or film running during pouring, thereby ensuring the strength and flatness of the integrated pouring.

[0061] When making the integrated module 40, first select a number of template blocks 41 and a number of back fringes 42, wherein the template block 41 is a plate made of metal, and its thickness and length are the same, preferably an aluminum alloy template, which is not only easy to obtain materials, but also not easy to deform. The back fringes 42 are steel back fringes, and their length is greater than the width of the integrated module 40, which is convenient for reinforcing the template block 41 to improve the overall strength of the integrated module 40.

[0062] All the template blocks 41 and the back frets 42 are controlled to be vertically cross-connected through the connecting pieces 45 to assemble into an integral one-piece module 40, and all the back frets 42 are arranged on the side of the one-piece module 40 away from the wall 10 to be built. All the back frets 42 are spaced and distributed in the length direction of the same side of the template block 41, so that the other side of the template block 41 is a flat plane, and the flat surface is arranged on the side close to the wall 10 to be built, so as to form a flat wall surface after pouring.

[0063] A disc nut 44 is fixedly arranged on the side of the back fret 42 away from the template block 41, and bolt holes 43 corresponding to the positions of the nuts 44 are arranged on the back fret 42 and the template block 41. The upper and lower ends of the template block 41 are provided with back frets 42 connected thereto, that is, the position of the outermost back fret 42 in the upper and lower ends of the template block 41 is first reserved and its position is ensured to be fixed, and the bolt holes 43 on the back fret 42 at the lowest position are the bolt holes 43 on the back fret 42 at the highest position corresponding to the casting of the integrated module 40 used when the wall 20 has been built. That is, a mounting hole corresponding to the bolt hole 43 is reserved in advance on the built wall 20 based on the position of the back rib 42 at the lowest position in the integrated module 40 (not shown in the figure); and the mounting hole corresponding to the bolt hole 43 at the position of the back rib 42 at the highest position in the integrated module 40 on the wall 10 to be built can be used as the lowest bolt hole 43 of the integrated module 40 in the next layer of the wall 10 to be built. Not only can the integrity of the connection between the upper and lower ends of all the template blocks 41 be guaranteed, but also the modularization and integration of the overall installation position can be guaranteed.

[0064] Furthermore, at the non-connected position between the template block 41 and the back fringes 42, the adjacent template blocks 41 are locked by a pin connection 46 formed by the cooperation of a pin and a pin sheet, which can improve the safety strength of the template blocks 41 spliced ​​together and make them integrated. The connecting piece 45 penetrates the thickness of the template block 41 and is welded to the back fringes 42, and the connecting piece 45 is located between the adjacent template blocks 41.

[0065] A lifting ring 47 fixed to the template block 41 is also provided on the top of the integrated module 40 for the purpose of facilitating installation, disassembly or transportation, and using a crane to shift and adjust the modular integrated module 40 to extend its service life. Preferably, at least two symmetrically arranged lifting rings 47 are provided on the top of the template block 41 to ensure stability during suspension.

[0066] S2, installing the integrated module 40 onto the built wall 20 below the wall 10 to be built.

[0067] like Figure 4 As shown, the hoist ring 47 is suspended by a crane to control the integrated module 40 to move to the gap 30 as a whole, and to make the flat surface of the integrated module 40 close to one side of the wall 10 to be built. Then, the top of the integrated module 40 is controlled to be set at the same height as the top of the wall 10 to be built, that is, to ensure that the top surface of the integrated module 40 is set flush with the top of the wall 10 to be built.

[0068] Under the condition that the upper end face of the integrated module 40 is suspended and positioned, the connection point of its lower end face is fixed and it is fixed to a set of walls 20. That is, from the inner side of the vertical section of the built wall 20, the screw rod 48 first penetrates the through hole prefabricated on the vertical section of the built wall 20, and then passes through the lowest row of bolt holes 43 in the integrated module 40, and then is fixedly matched with the nut 44 prefabricated on the back square 42. A nut is also used to match the screw rod 48 on one side close to the built wall 20. By adjusting the matching structure of the screw rod 48, the nut 44 fixedly welded on the back square 42, and the nut 44 movable on the wood square 52, the lower end of the integrated module 40 is completely connected to the vertical section of the built wall 20 to locate the position of the lower end face of the integrated module 40.

[0069] S3, tying steel bars at the location of the wall 10 to be built to form a steel grid body 60.

[0070] In such Figure 5 As shown, steel bars are tied at the location of the wall 10 to be built to form a steel grid body 60.

[0071] S4, assembling the split module 50 on the side of the wall 10 to be built away from the gap 30, and fixing the split module 50, the steel grid body 60 and the integrated module 40 together.

[0072] like Figure 6 As shown, a split module 40 is assembled on the side of the wall 10 to be built away from the gap 30, specifically:

[0073] First, a plurality of wooden templates 51 and a plurality of wooden squares 52 are selected. The wooden structure is selected, which is not only convenient for installation and assembly, but also convenient for obtaining materials, and is also easy to disassemble and adjust.

[0074] Then control all wooden templates 51 to be arranged vertically side by side in sequence along the width direction of the wall 10 to be built, and the height of all wooden templates 51 is the same as that of the wall 10 to be built, and make the top of the wooden template 51 flush with the top of the integrated template 40 and the wall 10 to be built, and the lower end of the wooden template 51 abuts against the upper end surface of the horizontal section of the built wall 20, so that the wooden template 51 forms an integral flat wall surface, which together with the integrated template 40 and the built wall 20 form an empty cavity, and the cavity side of the structure is a strong and non-deformable module to prevent leakage, the steel integrated module 40 and the wooden split module 50 form a high-strength and non-deformable structure, thereby avoiding the problem of bulging mold and film running. The steel mesh frame body 60 is framed in the cavity, and only concrete needs to be poured into the cavity.

[0075] On the side of the wood formwork 51 away from the wall 10 to be built, wood squares 52 are sequentially arranged along the lateral width direction of the split module 50. The positions of the wood squares 52 are arranged based on the positions of all the back squares 42 located above the built wall 10 in the integrated module 40, and the wood squares 52 are fixedly connected to the wood formwork 51 by screws, and the wood formworks 51 are connected to each other by pin connections 46 formed by pins and pin sheets between adjacent wood formworks 51, so as to form an integrated split module 50.

[0076] Then, the split module 50, the steel mesh frame body 60 and the integrated module 40 are molded and fixed, specifically:

[0077] First, based on the positions of the bolt holes 43 in the integrated module 40 located above the built wall 10 , holes are drilled on the wooden template 51 and the wooden square 52 , and the positions of the drilled holes and the bolt holes 43 on the integrated module 40 are made to correspond one to one.

[0078] On one side of the wooden square 52, the screw 48 penetrates the drilled holes on the wooden square 52 and the wooden template 51, the steel mesh body 60, and the bolt holes 43 on the template block 41 and the back square 42 in sequence, and then cooperates with the fixed nut 44 on the back square 42, and then a movable nut 44 is set on the side of the screw 48 close to the wooden square 52. By adjusting the degree of cooperation between the screw 48 and the nut 44, the wooden template 51 and the template block 41 are molded together, that is, the integrated module 40 and the split module 50 are molded together.

[0079] In order to improve the strength of the split module 50 , a bracket 53 for supporting the wooden template 51 is provided on the side of the wooden template 51 away from the wall 10 to be built.

[0080] S5. Pour concrete into the steel grid body 60 to obtain the wall body 10 to be built that is built integrally with the built wall body 20.

[0081] like Figure 7 As shown, after the mold is closed, concrete is poured directly into the cavity where the steel mesh is located between the integrated module 40 and the split module 50, and the concrete and the steel mesh frame body 60 are built as one, forming a wall 10 to be built that is cast and formed as one with the built wall 20.

[0082] A construction method for walls at gaps designed in the present application is adopted, in which a modular integrated module is combined on the template on the side close to the gap with a detachable module on the side away from the gap to obtain a cavity whose height and thickness dimensions completely match the wall structure to be built, and then concrete is poured into the cavity; this method can prevent problems such as leakage, mold expansion, and mold running when pouring walls at gaps, and is not only simple to operate and safe and reliable, but also can be repeatedly used.

[0083] The above detailed description of the embodiments of the present application is only a preferred embodiment of the present application and cannot be considered to limit the scope of implementation of the present application.
