Description

Technical Field

[0001] The present invention relates to a formwork with both lighting and elevation measurement functions and a construction method thereof, belonging to the field of large-volume concrete formwork. Background Art

[0002] At present, the main large-volume concrete formworks are integral large formworks and combined large formworks. After these formworks are supported, together with the steel columns placed in advance inside the large-volume concrete and a large number of threaded steel bars and stirrups tied, the sight for pouring concrete on site is dim, and the complex arrangement space seriously affects the flow of concrete, especially during night pouring. On-site pouring usually relies on visual inspection and experience to judge the distribution of concrete in the enclosed formwork cavity. However, due to the dim light, the blockage of steel plates and reinforcement bars, it is difficult to judge whether the concrete flow in the on-site formwork is uniform, and it is not clear which specific position is uneven. Workers can only pour along the pouring route based on experience and feeling, and only shift until obvious pushing of materials occurs, or the vibrating rod is dispersed. Although self-compacting concrete can be used, in the face of closely arranged reinforcement, if not dealt with in time, it will lead to stockpiling and hollowing, affecting the later quality of the concrete.

[0003] Therefore, it is necessary to develop a formwork with both lighting and elevation measurement functions and a construction method thereof. Summary of the Invention

[0034] The following further elaborates on the formwork with both lighting and elevation measurement functions and its construction method provided by the present invention in conjunction with the accompanying drawings and specific embodiments. In combination with the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non - precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0035] Embodiment 1

[0036] As Figures 1 to 5 shown, this embodiment provides a formwork 10 with both lighting and elevation measurement functions. The formwork 10 is a commonly used tool in concrete construction, including a panel 11 and a backing rib 12. In this embodiment, a vertically - arranged notch is provided on the panel 11 of the formwork 10, and several integrated measurement and night vision unit groups 20 are embedded in the notch. A signal box 30 is also provided on the formwork 10. A controller, a signal receiver, and a first power source are arranged in the signal box 30, and the first power source supplies power to the controller and the signal receiver.

[0037] The integrated measurement and night vision unit group 20 includes a rectangular box 21, several first light emitters 22, several photosensitive sensors 23, a signal transmitter, and a second power source. The signal transmitter and the second power source are arranged in the rectangular box 21, and the second power source supplies power to the first light emitters 22, the photosensitive sensors 23, and the signal transmitter.

[0038] Several spaced - apart chambers 211 are arranged along the length direction on the rectangular box 21. A first light emitter 22 and a photosensitive sensor 23 are arranged in each chamber 211. The first light emitter 22 can emit light in a direction perpendicular to the formwork. After the emitted light is diffusely reflected by the poured concrete 1, the photosensitive sensor 23 can detect the light diffusely reflected by the concrete 1.Figure 5 The optical path 25 in which the light emitted by the first light emitter 22 is received by the photosensitive sensor 23 is shown. When the photosensitive sensor 23 detects light, it will trigger the signal transmitter to emit a signal, which includes the number of the photosensitive sensor 23 or the first light emitter 22. The signal receiver in the signal box 30 is used to receive the signal emitted by the signal transmitter. The controller calculates the concrete pouring height according to the signal received by the signal receiver. For example, the formwork height can be measured in advance, and then the height of each photosensitive sensor 23 or the first light emitter 22 can be calculated. During the detection, only according to the number of the photosensitive sensor or the first light emitter in the signal, the height of the photosensitive sensor 23 or the first light emitter 22 in the signal can be obtained. According to the maximum height of the photosensitive sensor 23 or the first light emitter 22 included in the signal, it is used as the height of the poured concrete. As an example, a first light emitter 22 and a photosensitive sensor 23 are encapsulated in a stepped structure 24. The large-head part of the stepped structure 24 is made of a light-transmitting material, and the light of the first light emitter 22 is emitted towards the inner side of the formwork through the large-head part of the stepped structure 24. A number of stepped cavities 211 matching the stepped structure are provided on the rectangular box body. The stepped structure 24 is embedded in the stepped cavities 211. In order to facilitate the installation of the rectangular box body 21, a number of connecting ear plates 212 can be provided on the rectangular box body 21.

[0039] The formwork provided in this embodiment with both lighting and elevation measurement functions can directly emit light into the formwork as a construction light source through multiple first light emitters 22, which can solve the problem of dim light inside the formwork during night-time concrete pouring, and is beneficial to construction such as concrete placing and vibration. In addition, when the light emitted by the first light emitter 22 is covered by the poured concrete 1, the light will undergo diffuse reflection. At this time, the photosensitive sensor 23 can receive the diffusely reflected light, so that the controller can know which first light emitters 22 are covered by the concrete, and thus automatically identify the pouring height of the concrete. Therefore, the formwork provided in this embodiment with both lighting and elevation measurement functions can realize the functions of internal formwork lighting and automatic identification of the concrete pouring height.

[0040] Further, on one side of the rectangular box body 21 facing away from the light-emitting direction of the first light-emitting body 22, a scale groove 26 is arranged along the length direction. The starting end of the scale groove 26 communicates with the internal cavity of the rectangular box body 21. That is to say, each scale groove 26 is a scale line, and one end of the scale line communicates with the corresponding chamber 211. A second light-emitting body 27 is also arranged in each chamber 211. When the photosensitive sensor 23 detects the light diffusely reflected by the concrete, it triggers the second light-emitting body 27 to emit light towards the scale groove 26, and the light emits from the scale groove 26. The photosensitive sensor 23 can convert the optical signal into an electrical signal, and then can control the second light-emitting body 27 to emit light and go out through the circuit. The light emitted by the second light-emitting body 27 can pass through the scale groove 26, enabling the construction personnel to directly identify the height of the concrete pouring.

[0041] Further, a display screen is arranged on the signal box 30 for displaying the height of the concrete pouring. The worker can identify the height of the concrete pouring inside the formwork through the display.

[0042] Further, a warning lamp is arranged on the signal box 30. A control value of the concrete pouring height is preset in the controller. When the calculated concrete pouring height reaches the preset control value, the controller controls the warning lamp to emit light to prompt the construction personnel to adjust the position of the feeding port. This embodiment can facilitate the construction personnel to control the height of the concrete pouring.

[0043] Further, a slot hole 213 is arranged on the rectangular box body 21 at the starting end of the scale groove 26. The slot hole 213 communicates with the chamber 211 of the rectangular box body 21. A retaining strip 214 is arranged on the rectangular box body 21, and the retaining strip 214 covers the slot hole 213. The starting end of the scale groove 26 communicates with the inside of the slot hole 213.

[0044] Embodiment 2

[0045] This embodiment provides a construction method of the formwork with both lighting and elevation measurement functions. The following further describes the construction method in combination with Figures 1 to 5 and Embodiment 1. The construction method includes the following steps:

[0046] Step 1: Hoist and place the template 10 in place, install and fix it, measure the elevation of the template 10, input the template elevation into the controller, and the controller calculates the elevation of each photosensitive sensor 23; when measuring the elevation of the template 10, the top elevation or bottom elevation of the template can be measured, or the elevation of the measuring point set on the back of the template can also be measured, as long as the elevation of the photosensitive sensor 23 can be calculated. Of course, the elevation of the first light-emitting body can also be measured. Since the height of each chamber is small, the first light-emitting body 22 and the photosensitive sensor 23 can be regarded as having the same elevation, or the first light-emitting body and the photosensitive sensor 23 can be directly set at the same height;

[0047] Step 2: Make the first light-emitting body 22 emit light and illuminate the inside of the template 10;

[0048] Step 3: Pour the concrete 1 into the template 10. The light emitted by the first light-emitting body 22 within the poured height range is diffusely reflected by the concrete 1 and then received by the photosensitive sensor 23. The photosensitive sensor 23 triggers the signal transmitter to emit a signal, and the signal contains the number of the photosensitive sensor 23;

[0049] Step 4: The controller receives the signal emitted by the signal transmitter through the signal receiver and measures the pouring height of the concrete 1 according to the number of the photosensitive sensor 23.

[0050] Further, a concrete pouring height control value is preset in the controller, and a warning lamp is arranged on the signal box 30; the construction method further includes:

[0051] Step 5: When the concrete pouring height calculated by the controller reaches the preset control value, the controller controls the warning lamp to emit light, and the construction personnel move the placing boom to the next placing point.

[0052] Further, a second light-emitting body 27 is further arranged in the chamber 211. In Step 3, when the photosensitive sensor 23 detects the light diffusely reflected by the concrete, it triggers the second light-emitting body 27 to emit light towards the scale groove 26, and the light emits from the scale groove 26.

[0053] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
