Description

Technical Field

[0001] The utility model relates to the technical field of building engineering formwork, in particular to a screw-mounted setting-out opening box for building construction. Background Technique

[0002] During building construction, generally, axis control points are established on the plane of the building, marks are embedded, and then transmission openings are reserved at corresponding positions on each floor slab. Instruments such as laser plumbometers and theodolites are directly used at the axis control points, and their positions are vertically projected onto any floor through the reserved transmission openings for measurement. When pouring the floor slab of each floor, a setting-out opening box is embedded at the reserved transmission opening positioned by the control point. The setting-out opening box is to provide a standard setting-out opening for the concrete floor slab, running through the upper and lower floors and leading the setting-out from the bottom layer to the upper layer, which is convenient for construction workers to set out and also to ensure construction strictly in accordance with the design drawings.

[0003] Currently, for iron and wooden setting-out opening boxes, the positions of the openings of wooden products are easily damaged during form removal, and the molds are generally disposable. Iron products will rust due to environmental and operation problems, reducing the service life of the setting-out opening boxes. During form removal, the setting-out opening boxes are easily deformed and damaged, affecting the recycling of the next layer or even making them unusable, with low utilization rate, thus increasing the construction cost and causing waste of materials and labor. During the use of the box, due to the unstable installation method, it will be washed out of position by the concrete during concrete pouring, resulting in deviation or even completely incorrect positions of the formed setting-out openings. The assembly of the box requires welding, which will generate certain harmful gases during the operation process. The production operation is troublesome and requires professional personnel to operate, and it is not environmentally friendly during production. Using a deformed setting-out opening box will affect the size of the reserved line opening of the setting-out opening, resulting in the inability of the instrument to be vertically projected onto any floor for measurement, and there will also be a relatively cumbersome plugging procedure in the later stage.

[0004] The comparative document discloses a combined mold for setting-out holes in building construction, including: a steel box, which is welded by steel plates, with an open top cavity and a rectangular groove provided at the bottom; a connecting piece, which is flat-shaped, corresponding to the upper part of the rectangular groove and arranged at the top of the steel box, and a reserved round hole is provided in the middle of the connecting piece; a screw rod, which is a through-thread screw rod, and a fixing plate for rotating and fixing after passing through the rectangular groove and the floor formwork is provided at the bottom of the screw rod, and the top of the screw rod is fixed by a nut after passing through the reserved round hole. This prior art solves the problems that the setting-out hole box is prone to deformation and damage during demoulding, affecting the recycling of the next layer or being unable to be used again, with low utilization rate, thus increasing the construction cost and causing waste of materials and labor. However, since this prior art only fixes in the vertical direction and there is only one fixing point, there is still the problem of unstable installation method, being washed away by concrete during concrete pouring, resulting in deviation or even completely incorrect position of the formed setting-out hole. Secondly, the production operation is still too troublesome and not environmentally friendly. Summary of the Utility Model

[0005] The purpose of the present utility model is to overcome the problem that the installation structure of the existing setting-out hole box is unstable and prone to being washed away by concrete, and to provide a setting-out hole box for building construction with a stable installation structure and not prone to being washed away by concrete.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0007] A screw rod installation type setting-out hole box for building construction, including a shell, a screw rod installed on the shell, and a nut threadedly connected to the screw rod. The shell includes four side plates enclosing a cavity and a mounting frame arranged in the cavity and connected to the side plates. The mounting frame includes a connecting piece and a mounting sleeve located at the center inside the shell. One end of the connecting piece is fixedly connected to the mounting sleeve, and the other end of the connecting piece is fixedly connected to the side plate. The screw rod passes through the mounting sleeve and is threadedly connected to the nut, and the nut is located at one end of the screw rod close to the top of the shell; it also includes a fixing piece installed at the bottom of the shell, and the fixing piece is connected to one end of the screw rod close to the bottom of the shell.

[0008] During the operation of the above solution, the screw is first connected to the fixing member, then sleeved on the installation sleeve of the mounting bracket. Subsequently, the entire box is moved and placed at the designated position, and the fixing member is rotated to install it at the bottom of the housing. At the same time, the fixing member abuts against the building formwork, so that the fixing member fixes the entire setting-out box and makes the setting-out opening box fit with the building formwork. Finally, the nut is installed on the screw. When pouring concrete, the concrete impacts the setting-out box from all directions. The connecting member in the mounting bracket plays a supporting role for the side plate of the housing to prevent the side plate from being crushed. When the setting-out box floats, the pre-tightening force of the threaded connection between the screw and the nut restricts the housing on the fixing member, and the fixing member is fixedly connected to the building formwork, thus achieving the effect of preventing it from floating. When the impact of the concrete causes the setting-out box to rotate, shake or displace, the fixing member can restrict it on the building formwork to prevent it from rotating or displacing. When it needs to be disassembled after the construction is completed, the nut is loosened, and then the fixing member is rotated by a certain angle to separate it from the building formwork. Finally, the entire setting-out box is lifted out. The side wall can be set to have a certain reverse formwork slope, which is convenient for the separation of the concrete and the setting-out box and enables the housing to be taken out smoothly.

[0009] Preferably, the fixing member is snap-connected to the bottom of the housing, and the fixing member is in the shape of a cross-shaped rod. During installation, the fixing member is fixedly installed under the building formwork to provide additional support to ensure that the structure or component remains stable in the correct position and orientation, and to adjust the position of the box fixed on the building formwork to meet specific installation or use requirements.

[0010] Preferably, a first groove is provided on the side plate, and the fixing member is inserted into the first groove. The fixing member can rotate 360 degrees at the bottom of the box. During installation, the fixing member is rotated into the first groove at the bottom of the housing, and the nut is adjusted to lock the buckle to fix the setting-out opening box to fit and connect with the aluminum formwork, avoiding the situation of the box body floating, rotating and displacing when pouring concrete.

[0011] Preferably, a second groove is provided at the bottom of the mounting bracket, and the fixing member is provided with a protruding block that is snap-connected to the second groove.

[0012] Preferably, the length of the rod of the fixing member is greater than the distance between two opposite side plates of the housing and less than the diagonal distance between two opposite side plates at the bottom of the housing. The part protruding from the bottom side plate of the housing is fixedly connected to the building formwork to fix the entire setting-out box. The rod lengths of the two cross-shaped rods are less than the diagonal length of the rectangle at the bottom of the housing, which is convenient for the disassembly of the fixing member.

[0013] Preferably, the housing further includes a receiving area for placing the fixing member during disassembly, and the receiving area is located below the mounting bracket. At the bottom of the housing, the bottom plane of the mounting bracket inside the housing is higher than the bottom plane of the housing to form a receiving area, and the height difference between the two planes is at least the thickness of the fixing member to ensure that the receiving area can accommodate the entire fixing member.

[0014] Preferably, a handle is further provided at the top end of the housing.

[0015] Preferably, the handle is an arc-shaped or semi-circular curved panel provided at the top end of the side plate and extending outwards. The arc-shaped design can prevent the concrete splashed during operation from hanging on the handle during concrete pouring, and can also drain the concrete out of the handle to keep the handle clean. The embedded handle design is integrated with the overall box, enhancing the unity and coordination of the box, providing a simple appearance, and not causing accidental collisions and scratches due to protruding parts, and not being easily damaged due to impact or long-term use.

[0016] Preferably, both ends of the handle are fixedly connected to the inner walls of two opposite side plates respectively, and the handle is provided with a handle through hole for the screw rod to pass through; the housing further includes a handle cover plate, and raised portions for facilitating the disassembly of the handle cover plate are provided on both sides of the upper surface of the handle cover plate, and a cover plate upper mounting portion is provided on the lower surface of the handle cover plate; a cover plate lower mounting portion that is in interference fit with the cover plate upper mounting portion is provided inside the handle; an anti-slip edge is provided around the side plates at the top of the housing. The handle of this form is provided with an anti-slip edge around the housing at the top end of the side plate, and a customized LOGO can also be printed on the upper plane of the handle cover plate for reminder or identification purposes.

[0017] Preferably, a pin bar is further included, and a pin hole for mounting the pin bar is provided on the side surface at the end of the screw rod. After a nut is provided at the end of the screw rod, the pin bar is passed through the hole of the screw rod, and the end of the pin bar is unfolded to prevent the nut from disengaging from the screw rod during installation and rotation, resulting in the detachment of the fixing member.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] Through the cooperation among the screw, nut, fixing member, and fixing sleeve on the mounting bracket, the fixing member is fixed under the aluminum alloy building formwork and the housing is locked on the aluminum alloy building formwork. During the later concrete pouring process, when the setting-out box floats, the pre-tightening force of the threaded connection between the screw and the nut restricts the housing on the fixing member, and the fixing member is fixedly connected to the building formwork, finally preventing it from floating; when the setting-out box rotates or shifts under the influence of flowing concrete, the connection between the fixing member and the screw can prevent the box body from rotating and shifting; at the same time, the length of the screw can be adjusted according to the thickness of the building aluminum alloy formwork during use; the connecting plate on the mounting bracket plays a supporting role for the housing to improve the compressive structural strength.

[0033] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0034] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0035] Example 1

[0036] like Figure 1 The example shown is an embodiment 1 of a screw-mounted wire-release box for construction, a screw-mounted wire-release box for construction, comprising an object 1, a screw 2 mounted on the object 1 and a nut 3 threadedly connected to the screw 2, the object 1 comprising four side panels 101 enclosing a cavity and a mounting frame 102 disposed in the cavity and connected to the side panels 101, the mounting frame 102 comprising a connecting piece 1021 and a mounting sleeve 1022 located at the inner center of the shell 1, one end of the connecting piece 1021 is fixedly connected to the mounting sleeve 1022, and the other end of the connecting piece 1021 is fixedly connected to the side panel 101, the screw 2 passes through the mounting sleeve 1022 and is connected to the nut 3, the nut 3 is located at one end of the screw 2 near the top of the shell 1; it also comprises a fixing piece 4 mounted at the bottom of the shell 1, the fixing piece 4 is connected to one end of the screw 2 near the bottom of the shell 1.

[0037] Furthermore, the fixing member 4 is clamped with the bottom of the housing 1, and the fixing member 4 is in the shape of a cross rod. During installation, the fixing member 4 is fixedly installed under the building template to provide additional support, ensure that the structure or component remains stable in the correct position and direction, and adjust the position of the box fixed in the building template to meet specific installation or use requirements.

[0038] Specifically, the fixing member 4 is connected to the screw rod 2 through a countersunk through hole. The fixing member 4 is fixedly installed on the building formwork. It can be that the rod of the cross-shaped fixing member 4 is engaged with the groove on the building formwork.

[0039] Furthermore, a handle 103 is also provided at the top end of the housing 1.

[0040] Specifically, customized LOGOs can be printed on both the inner and outer surfaces of the side plates 101 for prompting or identification purposes. The position where the connecting member 1021 of the mounting frame 102 is fixedly connected to the side plate 101 is either at the midpoints of the four side plates 101 or at the edge between two adjacent side plates 101. Both positions have the same supporting effect; the side plates 101 around the upper part of the housing 1 form a trapezoidal quadrangular frustum, and the lower part is a cube. The trapezoidal side plates 101 may provide better stability. The trapezoidal flared shape usually has better resistance to concrete pressure than a rectangular shape because it can distribute the pressure more evenly. The trapezoidal design may increase the structural strength of the box, making it more resistant to deformation or damage. After the poured concrete is formed, the box is easier to demold, and the holes formed by the concrete are beautiful without damaging the box itself of the setting-out opening. A countersunk through hole is provided at the center of the cross-shaped fixing member 4. Before the screw rod 2 is inserted into the mounting sleeve 1022 of the mounting frame 102, it is first installed on the countersunk through hole of the fixing member 4, and the countersunk depth of the countersunk through hole is slightly greater than the thickness of the nut of the screw rod 2.

[0041] Specifically, the connecting member 1021 on the mounting frame 102 plays a supporting role in the housing 1 to improve the compressive structural strength. It can be manufactured by 3D printing with a lighter plastic material instead of the steel plate welding manufacturing method. This manufacturing method does not require professional welders and does not produce harmful gases, making it more environmentally friendly and efficient.

[0042] The working process or principle of this embodiment: First, the screw rod 2 is inserted into the countersunk through hole of the fixing member 4, then sleeved on the mounting sleeve 1022 of the mounting frame 102. Subsequently, the entire box is moved to the designated position, and the fixing member 4 is rotated to install it at the bottom of the housing 1. The fixing member 4 fixes the entire setting-out box so that the setting-out opening box fits with the building formwork, and at the same time, the fixing member 4 is fixedly connected to the building formwork. Finally, the nut 3 is installed on the screw rod 2. When pouring concrete, the concrete impacts the setting-out box from all directions. The connecting member 1021 in the mounting frame 102 plays a supporting role in the side plates 101 of the housing 1 to prevent the side plates 101 from being crushed. When the setting-out box floats, the pre-tightening force of the threaded connection between the screw rod 2 and the nut 3 restricts the housing 1 to prevent it from floating. When the impact of the concrete causes the setting-out box to rotate or shift, the fixing member 4 restricts it on the building formwork to prevent it from rotating or shifting. When it needs to be disassembled after the construction is completed, the nut 3 is loosened, then the fixing member 4 is rotated by a certain angle, and finally the entire setting-out box is lifted out.

[0043] Advantages of this embodiment: The fixing member 4 is fixed under the aluminum alloy building formwork. Through the cooperation among the screw 2, the nut 3, the fixing member 4, and the fixing sleeve of the mounting frame 102, the fixing of the line-setting box is achieved. During the later concrete pouring process, the four positions where the cross-shaped fixing member 4 engages with the housing 1 can prevent the box body from rotating and shifting. The length of the screw 2 can be adjusted according to the thickness of the building aluminum alloy formwork during use. The setting of the handle 103 facilitates the movement and disassembly of the box. When disassembling, only need to grip the handle 103 and apply force to take out the entire line-setting box.

It is characterized in that it further includes a fixing member 4 installed at the bottom of the housing 1, and the fixing member 4 is connected to one end of the screw 2 close to the bottom of the housing 1.

[0046] Specifically, the connecting member 1021 of the mounting frame 102 is a rectangular plate-shaped member, and the position where one end of the rectangular plate-shaped connecting member 1021 is fixedly connected to the housing 1 is the edge between two adjacent side plates 101.

[0047] Further, the fixing member 4 is snap-fitted to the bottom of the housing 1, and the fixing member 4 is in the shape of a cross-shaped rod.

[0048] Specifically, the shape of the housing 1 is a flared shape, that is, the upper part of the housing 1 is an inclined side plate 101, and the lower part of the housing 1 is a vertical side plate 101.

The fixing member 4 can rotate 360 degrees at the bottom of the box. During installation, the fixing member 4 rotates into the first groove 1011 at the bottom of the housing 1, and the adjusting nut 3 locks the buckle to fix the wire-releasing opening box to fit and connect with the aluminum formwork, avoiding the floating, rotation and displacement of the box body during concrete pouring, ensuring that the housing 1 is stable in the correct position and direction, and adjusting the position of the housing 1 fixed on the building formwork to meet specific installation or use requirements.

[0050] Further, the rod length of the fixing member 4 is greater than the distance between two opposite side plates 101 of the housing 1 and less than the diagonal distance between two opposite side plates 101 at the bottom of the housing 1.

[0051] Further, the housing 1 further includes a receiving area 1012 for placing the fixing member 4 during disassembly. The receiving area 1012 is located below the mounting frame 102. At the bottom of the housing 1, the bottom plane of the mounting frame 102 inside the housing 1 is higher than the bottom plane of the housing 1 to form the receiving area 1012. The height difference between the two planes is at least the thickness of the fixing member 4 to ensure that the receiving area 1012 can accommodate the entire fixing member 4.

[0052] Further, a handle 103 is also provided at the top end of the housing 1.

[0053] Further, the handle 103 is an arc-shaped or semi-circular curved panel provided at the top end of the side plate 101 and extending outward. The circular arc design can prevent the concrete splashed during operation from hanging on the handle 103 during concrete pouring, and can also drain the concrete out of the handle 103 to keep the handle 103 clean. The embedded handle 103 design is integrated with the whole box, enhancing the unity and coordination of the box, providing a simple appearance, not causing accidental collisions and scratches due to protruding parts, and not being easily damaged due to impacts or long-term use. In this embodiment, the handle 103 forms a ring-shaped whole around the side plate 101.

[0054] Further, a pin bar 5 is further included. A pin hole 201 for installing the pin bar 5 is provided on the end side surface of the screw rod 2. After setting the nut 3 at the end of the screw rod 2, the pin bar 5 is passed through the hole of the screw rod 2, and the end of the pin bar 5 is unfolded to prevent the nut 3 from disengaging from the screw rod 2 during installation rotation, resulting in the fixing member 4 disengaging.

[0055] The advantages of this embodiment over embodiment 1 are as follows: a fixing part 4 collection area 1012 is provided to facilitate the collection of the fixing part 4; an arc-shaped or semicircular handle 103 is provided on the top of the shell 1, which makes it easier to pick up, carry and move during construction, and is not limited to extraction on one side; a pin strip 5 is provided on the end side surface of the screw rod 2 to stop the nut 3 from detaching from the screw rod 2 during installation and rotation, causing the fixing part 4 to detach.
