A concrete module for integrated concrete modular housing and its processing method

Abstract

This invention belongs to the field of modular building technology, and particularly relates to a concrete module for integrating concrete modular boxes. The pre-embedded elements in this concrete module are embedded within the wall formwork, with their outer surfaces flush with the front surface of the wall formwork. All positioning parts of the pre-embedded elements are arranged and fixed to the inner surface of the plate along the height direction and are fixed to the mesh in the wall formwork. The processing method of the concrete module is as follows: first, the pre-embedded elements are processed and hoisted into the mold; then, the mesh is hoisted into the mold and fixed; then, the lifting ring is fixed; and finally, concrete is poured. Thus, the pre-embedded elements of this invention are used to fix the lifting ring, and the plate and positioning parts can respectively generate tensile forces with the wall and mesh in the wall formwork to increase the friction between the pre-embedded elements and the wall formwork. This not only ensures the normal hoisting of the concrete module but also prevents cracking of the wall formwork and deformation of the lifting ring, avoiding the delay in construction progress and material waste caused by rework and repairs, thus preventing unnecessary economic losses.

Description

Technical Field

[0001] This invention belongs to the field of modular building technology, and in particular relates to a concrete module for integrating concrete modular boxes and its processing method. Background Technology

[0002] Modular concrete construction is a new type of building that transforms the construction unit from two-dimensional precast concrete components of traditional prefabricated buildings into three-dimensional concrete modular boxes. This not only improves the overall prefabrication rate and integration of the building, but also highly integrates structural, interior and exterior decoration, electromechanical, water supply and drainage and HVAC elements into one unit. On-site construction can be completed by simply pouring the connection area, connecting pipelines and doing a small amount of decoration work after the modules are hoisted. It is the best carrier for building industrialization and intelligent construction.

[0003] However, although concrete modular boxes have a high degree of integration and fast construction speed, the hoisting of the concrete modules is a major challenge in the construction process. The wall formwork in the concrete modules is a thin plate made of high-strength concrete and steel mesh. The thin plate is large in volume and heavy, so it is very easy to crack during hoisting. The lifting rings are also very easy to deform, which seriously affects the construction progress and causes unnecessary economic losses. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a concrete module for integrating concrete modular boxes and its processing method, thereby solving the technical problems of wall formwork cracking and lifting ring deformation during the hoisting process of concrete modules.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] On one hand, the present invention provides a concrete module for an integrated concrete modular box, including a wall formwork and a lifting ring. The lifting ring is U-shaped, with its open end facing downwards and its closed end and open end located on the upper and lower sides of the upper edge of the wall formwork, respectively. It also includes a pre-embedded element embedded in the wall formwork, with the outer surface of the pre-embedded element flush with the front surface of the wall formwork. The pre-embedded element includes a plate and several positioning parts, all of which are arranged and fixed to the inner surface of the plate along the height direction of the plate. The open end of the lifting ring is fixed to the top outer surface of the plate. The wall formwork includes a mesh, and all positioning parts are fixed to the mesh.

[0009] Furthermore, the wall formwork also includes the wall itself, with the mesh panel located between the front and rear walls of the wall.

[0010] Furthermore, the plate has several positioning holes along its height direction, all of which are circular and evenly distributed along the height direction of the plate.

[0011] Furthermore, the distance between the top of the uppermost positioning hole and the upper edge of the plate and the distance between the bottom of the lowermost positioning hole and the lower edge of the plate are both not less than 350mm.

[0012] Furthermore, the positioning section includes a welding section and two binding sections. The two binding sections are parallel to the welding section and are located on both sides of the welding section, symmetrical about the welding section. The welding section and the binding section are located on different straight lines. The mesh includes several horizontal ribs and several vertical ribs. The vertical ribs are located in front of the horizontal ribs. The welding section of each positioning section is welded to the inner surface of the plate, so that the two binding sections and the horizontal ribs are located on the same vertical plane and the two binding sections are in contact with the lower side of a horizontal rib and fixed to the horizontal rib.

[0013] On the other hand, the present invention also provides a method for processing concrete modules for integrated concrete module boxes, comprising the following steps:

[0014] S1: Process the plate body so that its height does not exceed the height of the concrete module mold;

[0015] S2: Arrange all positioning parts along the height direction of the plate and fix them to the inner surface of the plate to form embedded elements;

[0016] S3: Hoist the embedded component into the mold, so that the front surface of the plate is in contact with the inner surface of the front side of the mold, and temporarily fix the position of the embedded component.

[0017] S4: Hoist the mesh into the mold and temporarily fix its position;

[0018] S5: Fix the pre-embedded components to the mesh using the positioning part;

[0019] S6: Fix the open end of the lifting ring to the top outer surface of the plate;

[0020] S7: Pour concrete into the mold to form a wall mold, and ensure that the height of the vibrated concrete is not less than the height of the slab.

[0021] S8: After the concrete has reached the demolding strength, the mold is removed to form a concrete module.

[0022] Furthermore, in step S1, a number of positioning holes are made on the plate along the height direction, so that the line connecting the centers of all the positioning holes coincides with the center line of the plate.

[0023] Furthermore, before step S2, step S20 is included: processing the positioning part so that the distance between the straight line where the welding section is located and the straight line where the two binding sections are located is consistent with the distance between the plane where the mesh is located and the inner surface of the plate.

[0024] Furthermore, in step S2, all the positioning parts fixed on the plate are aligned at both ends.

[0025] Furthermore, in step S7, when pouring concrete, ensure that the positioning hole is filled with concrete.

[0026] (III) Beneficial Effects

[0027] The beneficial effects of this invention are:

[0028] This invention provides a concrete module for integrated concrete modular box and its processing method. Pre-embedded elements are added to the wall formwork for fixing lifting rings. The plate and positioning parts of the pre-embedded elements can generate tensile forces with the wall and mesh in the wall formwork, increasing the friction between the pre-embedded elements and the wall formwork. Compared to existing technologies, this invention provides a pre-embedded form that can be arranged in the wall formwork for fixing lifting rings. This not only ensures the normal hoisting of the concrete module but also prevents wall formwork cracking and lifting ring deformation, avoiding rework and repairs that would prolong construction time and waste materials, thus preventing unnecessary economic losses.

[0036] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0037] like Figure 1-3 As shown, this invention provides a concrete module for integrating concrete modular boxes, including a wall formwork 1, a lifting ring 2, and embedded elements 3. The wall formwork 1 is the enclosure structure of the concrete modular box, the lifting ring 2 is the lifting part for hoisting the concrete module, and the embedded elements 3 are fixing parts for fixing the lifting ring 2. The wall formwork 1 is thin plate-shaped, the embedded elements 3 are embedded in the wall formwork 1, the lifting ring 2 is U-shaped, the open end of the lifting ring 2 faces downward, and the closed end and the open end of the lifting ring 2 are located on the upper and lower sides of the upper edge of the wall formwork 1, respectively.

[0038] Specifically, such as Figure 2 As shown, the embedded element 3 includes a plate 31 and several positioning parts 32. All positioning parts 32 are arranged and fixed to the inner surface of the plate 31 along the height direction of the plate 31. This ensures that the outer surface of the plate 31 is flush with the front surface of the wall formwork 1 and that the plate 31 is not higher than the height of the wall formwork 1. Figure 3 As shown, the open end of the lifting ring 2 is fixed to the outer surface of the top end of the plate 31. In this embodiment, the lifting ring 2 is welded to the plate 31, and the weld seam is distributed on the inner and outer sides of the open end of the lifting ring 2. This ensures uniform stress distribution while preventing weld defects from affecting lifting safety.

[0039] like Figure 1 As shown, the wall formwork 1 includes a mesh panel 11 and a wall 12, with the mesh panel 11 located between the front and rear walls of the wall 12. All positioning parts 32 are fixed to the mesh panel 11.

[0040] Specifically, such as Figure 2As shown, the positioning part 32 includes a welding section 321 and two binding sections 322. The two binding sections 322 are parallel to the welding section 321 and are located symmetrically on both sides of the welding section 321. The welding section 321 and the binding sections 322 are on different straight lines. The mesh 11 includes several horizontal ribs 111 and several vertical ribs 112, with the vertical ribs 112 located in front of the horizontal ribs 111. The welding section 321 of each positioning part 32 is welded to the inner surface of the plate 31, so that the two binding sections 322 and the horizontal ribs 111 are located on the same vertical plane, and the two binding sections 322 contact the lower side of one horizontal rib 111 and are bound to it. When the concrete module is hoisted, an interaction force is generated between the binding section 322 and the horizontal rib 111, increasing the friction of the embedded element 3 in the wall formwork 1. Meanwhile, in order to ensure that the positioning part 32 is subjected to uniform force on both sides during the hoisting process, the two binding sections 322 are symmetrical about the plate 31, and the two ends of all the positioning parts 32 fixed on the plate 31 are aligned.

[0041] like Figure 1 As shown, to increase the friction between the embedded element 3 and the wall formwork 1, the plate 31 has several positioning holes 33 along its height. When concrete is poured into the mold, the concrete fills all the positioning holes 33 and forms concrete sheets within them. When the concrete module is hoisted, the upward force exerted by the concrete sheets on the positioning holes 33 and the downward force exerted by the positioning holes 33 on the concrete sheets will enhance the friction between the embedded element 3 and the wall formwork 1.

[0042] Preferably, the positioning holes 33 are set to be circular so that the concrete can more easily fill the positioning holes 33, and the equal spacing along the height direction of the plate 31 will make the wall formwork 1 be subjected to uniform force.

[0043] It should be noted that the distance between the top of the uppermost positioning hole 33 and the upper edge of the plate 31 and the distance between the bottom of the lowermost positioning hole 33 and the lower edge of the plate 31 are both not less than 350mm, so as to prevent the force transmission effect from being affected due to the small contact area between the upper and lower ends of the plate 31 and the wall formwork 1 during the hoisting process.

[0044] The present invention also provides a method for processing concrete modules for integrated concrete modular boxes, the steps of which are as follows:

[0045] S1: Process the plate 31 so that its height does not exceed the height of the concrete module mold, and open a number of positioning holes 33 along the height direction on the plate 31. All positioning holes 33 are evenly distributed on the plate 31 and the line connecting the centers of all positioning holes 33 coincides with the center line of the plate 31.

[0046] S20: Process the positioning part 32 so that the distance between the straight line where the welding section 321 is located and the straight line where the two binding sections 322 are located is consistent with the distance between the plane where the mesh 11 is located and the inner surface of the plate 31, so as to ensure that the outer surface of the plate 31 is flush with the front surface of the wall formwork 1 when the concrete is poured later.

[0047] S2: Arrange all positioning parts 32 along the height direction of the plate 31 and fix them to the inner surface of the plate 31 to form embedded elements 3. At this time, the positioning parts 32 are perpendicular to each other along the length direction of the plate 31 and the two ends of all positioning parts 32 fixed on the plate 31 are aligned.

[0048] S3: Hoist the embedded component 3 into the mold so that the front surface of the plate 31 is in contact with the inner surface of the front side of the mold. Temporarily fix the position of the embedded component 3 to ensure that the outer surface of the plate 31 is flush with the front surface of the wall mold 1 when the concrete is poured later.

[0049] S4: Hoist the mesh 11 into the mold and temporarily fix the position of the mesh 11.

[0050] S5: Fix the pre-embedded element 3 to the mesh 11 through the positioning part 32, and tie it to the corresponding horizontal reinforcement 111 according to the position of the binding section 322.

[0051] S6: Fix the open end of the lifting ring 2 to the top outer surface of the plate 31.

[0052] S7: Pour concrete into the mold to form wall mold 1, and ensure that the height of the concrete after vibration is not less than the height of the slab 31. When pouring concrete, ensure that the positioning hole 33 is filled with concrete to increase the friction between the embedded component 3 and the wall mold 1 during hoisting.

[0053] S8: After the concrete has reached the demolding strength, the mold is removed to form a concrete module, which is then hoisted to the concrete module box area for assembly.
