Description

TECHNICAL FIELD

[0001] The present application relates to a house construction method, in particular to a low-rise frame-masonry structure house construction method. BACKGROUND

[0002] Frame-masonry structure is a building structure form combining the characteristics of frame structure and masonry structure, and is the main form of self-built houses in rural areas. In frame-masonry structure, beams and columns are made of reinforced concrete and serve as the main load-bearing part of the building, while load-bearing walls are made of masonry structure and are mainly used for space division and additional support.

[0003] On the one hand, the load-bearing walls of the existing frame-masonry structure are generally made of bricks, and the cost of bricks is relatively high at present. In addition, after the wall construction is completed, the wall surface needs to be plastered, resulting in high construction cost, low efficiency and a large amount of labor. On the other hand, the column structure of the existing frame-masonry structure is cast on site, and many construction operations need to be performed on site. The above factors result in the problems of low efficiency and high cost in the construction of the existing frame-masonry structure house.

[0004] Therefore, there is an urgent need for a construction method that can quickly construct frame-masonry structure houses and has low cost. SUMMARY

[0005] The purpose of the present application is to provide a low-rise frame-masonry structure house construction method to solve the problems of low efficiency and high cost in the construction of the existing frame-masonry structure house.

Transport the prefabricated wall structural columns to the construction site, connect the wall structural columns to the foundation structural columns in the corresponding positions through sleeve grouting to form a whole, correct the position and verticality of the wall structural columns and fix them.

[0015] i. After the connection between the wall structural column and the foundation structural column reaches the set strength, the wall forming device is set between the two wall structural columns at both ends of the wall to be constructed. The wall structural columns are used to correct the verticality of the wall forming device and the wall thickness. Dry hard concrete is poured into the wall forming device between the two foundation structural columns. The wall forming device is used to pour and compact the concrete layer by layer from bottom to top until it reaches the height of the bottom of the ring beam or the bottom of the main beam.

[0016] j. Complete the construction work for each load-bearing wall of the house according to step i.

[0017] k. After the load-bearing walls of the house reach the set strength, support the ring beams, main beams, and top formwork, tie the reinforcing bars of the ring beams, main beams, and floor slabs, and pour concrete to form the main structure of the house.

[0018] l. If the house design is two or more stories, continue the main construction of the house according to steps h~k.

[0019] Furthermore, the wall forming device includes a wall forming plate, which is disposed on both sides of the wall to be constructed. The inner side of the wall forming plate is attached to the side of the structural column, and the wall forming plates on both sides of the wall are connected and fixed to each other by a number of tie bolts.

[0020] Furthermore, the wall forming device also includes a traveling track, a forming machine frame, a lifting mechanism, a mounting frame, a vibrating plate, a vibrator, and a traveling mechanism. The traveling track is installed on the upper end of the wall forming plate, the forming machine frame is located above the wall forming plate, the lifting mechanism is located on the forming machine frame, the mounting frame is located at the lower end of the lifting mechanism and is driven to move up and down by the lifting mechanism, the vibrating plate is flexibly located below the mounting frame, a vibrator is installed on the vibrating plate, and the traveling mechanism is located on the forming machine frame for moving along the traveling track.

[0021] Furthermore, the bottom of the main reinforcement bar of the foundation structural column is bent out of the edge of the cross-section of the structural column for binding with the foundation footing reinforcement bar to form an integral reinforcement mesh for the foundation footing. A reinforcement connecting sleeve is provided at the upper end of the top reinforcement bar of the foundation structural column, and a ground beam connecting reinforcement bar is pre-set on the foundation structural column.

[0022] Furthermore, both the foundation structural column and the wall structural column are provided with toothed joints extending towards the wall, and tie bars are provided on both the foundation structural column and the wall structural column extending towards the wall.

[0023] Furthermore, in step e, the pouring height of each layer of dry-hard concrete is 200-400 mm.

[0024] Furthermore, the cross-sectional shape of the wall structural column is consistent with the cross-sectional shape of the foundation structural column at the corresponding position, and an insertable steel bar corresponding to the depth of the steel bar connection sleeve of the foundation structural column is reserved at the lower end of the wall structural column.

[0025] Furthermore, for single-story buildings, the top of the main reinforcement bars of the wall structural columns is capped with hooks, and no concrete is poured within the height range of the top slab of the upper ring beam; for two-story or multi-story buildings, the top of the main reinforcement bars of the wall structural columns is connected with a steel sleeve, the top of the steel sleeve is flush with the top of the floor slab, and no concrete is poured within the height range of the top slab of the ring beam.

[0026] Furthermore, in step i, the pouring height of each layer of dry-hard concrete shall not exceed 3000 mm, and the next pouring shall be performed at least 12 hours after each pouring.

[0027] Furthermore, in step i, templates are set up at the door and window openings to reserve the door and window openings. When the dry-hard concrete is poured onto the surface of the door and window openings, the pre-tied lintel steel cage is placed before the next layer of dry-hard concrete is poured.

[0028] In the construction method of low-rise frame-concrete structure houses of the present invention, prefabricated structural columns are used, enabling rapid installation and positioning of the structural columns on the construction site. Then, using the structural columns, whose position and verticality have been corrected, the verticality of the wall forming device and the wall thickness are determined. Dry-hardened concrete, sufficient to meet the wall's compressive strength, is poured into the wall forming device in layers and compacted by vibration to form a load-bearing wall. The verticality and thickness of the load-bearing wall are effectively guaranteed. Utilizing the low slump of dry-hardened concrete, after the wall has been compacted to a certain height, the wall forming device can be lifted or moved for subsequent wall pouring and forming. This invention can quickly complete the construction of the load-bearing wall between two structural columns, replacing the original brick wall structure with dry-hardened concrete, eliminating the need for bricklaying. Furthermore, the load-bearing wall produced by the wall forming device has a smooth surface, eliminating the need for plastering. Therefore, this invention improves the construction efficiency of load-bearing walls and reduces their construction costs.

[0029] This invention utilizes precast structural columns combined with dry-hardened concrete load-bearing walls, which significantly improves the construction efficiency of frame-concrete structure buildings, reduces labor and costs, and ensures construction quality. This invention is applicable to the construction of low-rise frame-concrete structure buildings, especially those with six stories or less. Attached Figure Description

[0041] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] like Figures 1 to 10 As shown, the construction method for low-rise frame-concrete structure houses of the present invention specifically includes the following steps.

[0044] a. First, a concrete foundation layer is constructed on the prepared house foundation. On the concrete foundation layer, the positioning axes of each wall of the house and the edge line of the foundation footing 1 are laid out. The foundation footing 1 formwork is erected along the edge line of the foundation footing 1. b. Transport the prefabricated foundation structural columns 2 to the construction site. Each foundation structural column 2 is prefabricated in the workshop. At each internal and external corner of the building foundation, grout the foundation structural columns 2 at the corresponding positions on the cushion layer according to the positioning axis to stabilize the foundation structural columns 2, and correct the position and verticality of the foundation structural columns 2.

[0045] The thickness of each basic structural column 2 is the same as the thickness of the corresponding wall.

[0046] Among them, the basic structural columns 2 are divided into corner columns, T-shaped columns, cross columns, flat columns, etc. according to the building layout. The steel reinforcement ratio of each basic structural column 2 is based on the building height and number of floors, and the diameter and number of columns are designed according to the specifications.

[0047] The bottom of the main reinforcement bars of each foundation structural column 2 is bent at a right angle and extends outward by about 500 mm from the cross-sectional edge of the structural column. This is used to tie with the reinforcement bars of the foundation footing 1 to form an integral reinforcement mesh for the foundation footing 1. A reinforcement connecting sleeve 17 is installed at the top end of the top reinforcement bars of the foundation structural column 2. The reinforcement connecting sleeve 17 is generally located 800 mm above the zero level of the building. Ground ring beam connecting reinforcement bars 16 are pre-installed on the foundation structural column 2. The ground ring beam connecting reinforcement bars 16 are generally located 100 mm below the zero level of the building, and the diameter, number, and distribution position of the ground ring beam connecting reinforcement bars 16 correspond to the foundation ground ring beam 9.

[0048] like Figure 4 As shown, toothed joints are pre-reserved on the sides where each basic structural column 2 connects to the wall. The height of the toothed joint can be 300 mm and the depth can be 50 mm. Tie bars 15 are also pre-reserved on the sides where each basic structural column 2 connects to the wall. Tie bars 15 with a length of 1000 mm and a diameter of 6 mm can be pre-reserved every 500 mm in height. The tie bars 15 can increase the connection strength between the basic structural column 2 and the wall.

[0049] c. Set the foundation footing 1 reinforcement inside the foundation footing 1 formwork, tie the foundation footing 1 reinforcement to the reserved reinforcement at the bottom footing of each foundation structural column 2 to form the overall reinforcement mesh of foundation footing 1, and then carry out concrete pouring construction on the foundation footing 1 formwork to obtain the strip foundation footing 1.

[0050] d. such as Figure 1 , Figure 2 As shown, after the concrete of the foundation footing 1 reaches the set strength, the wall forming device is set between the two foundation structural columns 2 at both ends of the wall to be constructed, and the verticality of the wall forming device and the wall thickness are corrected by the foundation structural columns 2.

[0051] The wall forming device includes wall forming plates 3, which are installed on both sides of the wall to be constructed. During construction, the wall forming plates 3 on both sides of the wall are connected and fixed to each other by several tie bolts 4, so that the inner surface of the wall forming plates 3 fits tightly against the side of the foundation structural column 2. Since the position and verticality of the foundation structural column 2 are corrected in step b, when the position and verticality of the foundation structural column 2 are accurate, the position and verticality of the wall forming plates 3 on both sides can also be ensured. Therefore, the position and verticality of the wall obtained after filling the space between the wall forming plates 3 with concrete can also be guaranteed.

[0052] like Figure 6 , Figure 7 , Figure 8 As shown, in one embodiment of the present invention, the wall forming device further includes a traveling track 5 and a wall forming machine 6. The wall forming machine 6 includes a forming machine frame 6-1, a lifting mechanism, a mounting frame, a vibrating plate 6-8, a vibrator 6-9, and a traveling mechanism.

[0053] The wall forming panel 3 specifically includes a main panel 7 and a secondary panel 8. The main panel 7 is generally available in two lengths: three meters and four meters. The length of the secondary panel 8 is selected according to the length of the wall. Flanged edges can be set at the ends of the main panel 7 and the secondary panel 8. Adjacent main panels 7 and secondary panels 8 are spliced ​​together and connected to each other by bolts and other connecting parts.

[0054] The traveling track 5 is installed on the upper end of the wall forming panel 3. When the wall forming panel 3 is formed by splicing the main panel 7 and the auxiliary panel 8, the traveling track 5 is also spliced ​​from sections of corresponding length. The forming machine frame 6-1 is set above the wall forming panel 3, the lifting mechanism is set on the forming machine frame 6-1, and the mounting frame is set at the lower end of the lifting mechanism, which drives the mounting frame to move up and down. The vibrating plate 6-8 is set below the mounting frame and is flexibly connected to the mounting frame. A vibrator 6-9 is set on the vibrating plate 6-8. The traveling mechanism is set on the forming machine frame 6-1 and is used to move along the traveling track 5.

[0055] The walking track 5 can be made of profiles such as channel steel and I-beams.

[0056] Four lifting mechanisms can be provided, distributed at the four corners of the molding machine frame 6-1. Specifically, each lifting mechanism can be a screw 6-2 and nut 6-3 mechanism. The nut 6-3 is mounted on the molding machine frame 6-1, and the screw 6-2 is vertical and passes through the nut 6-3. A drive motor 6-5 and a transmission box 6-4 are mounted on the molding machine frame 6-1. The outer ring of the nut 6-3 has a worm gear structure. The drive motor 6-5 rotates through the transmission box 6-4, causing the screw 6-2 to move up and down along the axial direction. This allows the mounting frame, vibrator 6-9, and vibrating plate 6-8 to move up and down together between the wall molding plates 3 on both sides to perform compaction operations on dry-hard concrete of different heights.

[0057] The vibrating plate 6-8 is flexibly connected to the mounting frame via a spring 6-7. The vibrator 6-9 can be a vibrating motor, which drives the vibrating plate 6-8 to vibrate. The vibration and its own weight are used to compact the dry and hard concrete. The flexible connection can minimize the transmission of vibration to the mounting frame.

[0058] The traveling mechanism includes support legs 6-10 installed on the lower part of the molding machine frame 6-1, with at least two support legs 6-10 on each side. Traveling wheels 6-11 are provided on the inner side of the support legs 6-10, and the traveling wheels 6-11 are placed on the traveling track 5, allowing the molding machine frame 6-1 to move along the traveling track 5. To ensure stability during travel, inwardly bent hooks 6-12 can also be provided at the lower end of the support legs 6-10. The edge of the traveling track 5 extends beyond the outer surface of the wall molding plate 3, and the hooks 6-12 are located below the traveling track 5, preventing the molding machine frame 6-1 from derailing from the track.

[0059] The upper end of the support leg 6-10 is connected to the molding machine frame 6-1 by bolts and oblong holes, so that the support leg 6-10 and the molding machine frame 6-1 are adjustable. The distance between the support legs 6-10 on both sides can be adjusted. At the same time, different width mounting brackets and vibration plates 6-8 can be replaced to adapt to walls of different thicknesses.

[0060] The wall forming device can quickly perform compaction of dry-hard concrete by vibration. It is applicable to walls of different lengths and widths, can be reused for construction, saves a lot of manpower, and has low overall cost.

[0061] For locations where the wall forming device cannot perform compaction due to structural interference, compaction is performed manually using a small vibrator 6-9.

[0062] e. Pour dry-hardened concrete into the wall forming device between the two foundation structural columns 2. Use the wall forming device to pour and compact the concrete layer by layer from bottom to top until it reaches the lower surface of the ground beam 9. The resulting load-bearing wall is as follows: Figure 3 As shown. The reinforcing bars of the ground beam 9 are tied to the pre-reserved reinforcing bars at the top of the foundation structural column 2 to form an integral ground beam 9 reinforcing mesh. Using a wall forming device, dry-hard concrete is poured in and compacted by vibration to form the ground beam 9.

[0063] Dry-hard concrete, defined as concrete with a slump of less than 10 mm, can be rapidly molded and has a short setting time. After the compaction operation is completed, the wall forming panels 3 on both sides of the wall can be removed immediately, improving the turnover efficiency of the wall forming device. After compaction, dry-hard concrete exhibits excellent load-bearing capacity and can be used as a material for load-bearing walls 14.

[0064] A concrete placing boom can be used to pour dry-hard concrete. Within the height range of the wall forming panel 3, pouring can be done in multiple layers. After the wall within the height range of the wall forming panel 3 is poured and formed, the tie bolts 4 on the wall forming panel 3 are removed, and the wall forming panels 3 on both sides are taken off. The entire panel is then lifted to the next height and re-fixed. The pouring and compaction of dry-hard concrete continues until the construction of that wall is completed. After completing one wall, the wall forming device can be disassembled and moved to the next wall for construction.

[0065] Since tie bolts 4 are installed between the two wall forming plates 3, when encountering tie bolts 4, the mounting plate 6-6 needs to be lifted to bypass tie bolts 4 before continuing the pressure vibration operation.

[0066] The pouring height of each layer of dry-hard concrete is 200-400 mm.

[0067] f. According to steps c~e, construct the load-bearing walls 14 of each house foundation until the construction of the entire house foundation is completed.

[0068] g. After the building foundation reaches the set strength, backfilling is carried out, and after the backfill soil is compacted, the indoor ground subbase is constructed.

[0069] h. Each wall structural column 10 is prefabricated in the workshop. The prefabricated wall structural columns 10 are transported to the construction site. The wall structural columns 10 are connected to the foundation structural columns 2 in the corresponding positions by grouting through sleeves to form a whole. The position and verticality of the wall structural columns 10 are corrected and fixed.

[0070] The thickness of each building structural column is the same as the thickness of the corresponding wall, and the cross-sectional shape of each building structural column is consistent with the cross-sectional shape of the corresponding foundation structural column 2.

[0071] Among them, building structural columns are divided into corner columns, T-shaped columns, cross columns, flat columns, etc., according to the building layout. The steel reinforcement ratio of each building structural column is based on the building height and number of floors, and the diameter and number of columns are designed according to the specifications.

[0072] like Figure 5 As shown, toothed joints are pre-installed on the sides where each structural column connects to the wall. The height of the toothed joint can be 300 mm and the depth can be 50 mm. Tie bars 15 are also pre-installed on the sides where each structural column connects to the wall. Tie bars 15 with a length of 1000 mm and a diameter of 6 mm can be pre-installed every 500 mm in height. The tie bars 15 increase the connection strength between the structural column and the wall.

[0073] An insertable steel bar 18 is reserved at the lower end of the wall structural column 10, corresponding to the depth of the steel bar connecting sleeve 17 on the foundation structural column 2. When installing the upper wall structural column 10, the insertable steel bar 18 is inserted into the steel bar connecting sleeve 17 of the lower structural column.

[0074] For single-story buildings, the top of the main reinforcement bars of the wall structural column 10 is capped with hooks 6-12, and no concrete is poured within the height range of the top slab of the upper ring beam 11, so that the roof slab can be constructed directly afterward. For two-story or multi-story buildings, the top of the main reinforcement bars of the wall structural column 10 is connected with a steel sleeve, the top of the steel sleeve is flush with the top of the floor slab, and no concrete is poured within the height range of the top slab of the ring beam 11, so as to facilitate the construction of the upper floors.

[0075] i. After the connection between the wall structural column 10 and the foundation structural column 2 reaches the set strength, the wall forming device is set between the two wall structural columns 10 at both ends of the wall to be constructed. The wall structural columns 10 are used to correct the verticality of the wall forming device and the wall thickness. Dry hard concrete is poured into the wall forming device between the two foundation structural columns 2. The wall forming device is used to pour and compact the concrete layer by layer from bottom to top until it reaches the height of the bottom of the ring beam 11 or the bottom of the main beam.

[0076] The structure and usage of the wall forming device are the same as in steps e and d above, but the pouring height of each layer of dry-hard concrete should not exceed 3000 mm, and the next pour should be made at least 12 hours after each pour. Generally, one to three pours are sufficient to reach the level of the ring beam 11 or the bottom surface of the main beam. The resulting building structure is as follows: Figure 9 As shown.

[0077] like Figure 10 As shown, during the pouring process, a template is set at the door and window opening 12 to reserve the door and window opening 12. When the dry-hard concrete is poured to the surface of the door and window opening 12, the pre-tied lintel steel cage 13 is placed before the next layer of dry-hard concrete is poured.

[0078] j. Complete the construction work of each load-bearing wall 14 according to step i.

[0079] k. After the load-bearing walls 14 of the house reach the set strength, support the ring beam 11, the main beam, and the top formwork, tie the reinforcing bars of the ring beam 11, the main beam, and the floor slab, and pour concrete to form the main structure of the house.

[0080] l. If the house design is two or more stories, continue the main construction of the house according to steps h~k until the construction of the entire house is completed.

[0081] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
