Description

Technical Field

[0001] This utility model relates to the technology of concrete pouring for trenches, specifically to a movable and adjustable trench formwork. Background Technology

[0002] Traditional trench construction methods use a timber support system, employing wooden templates and support structures, which are fabricated and installed on-site according to the construction scenario. Although this method is relatively low-cost, it is difficult to adapt to complex designs such as irregular curved surfaces and cantilever structures, and it cannot be flexibly applied in sites where pre-embedded supports are limited.

[0003] CN204899216U discloses a lightweight trench formwork support device. The formwork can be made of fair-faced concrete, steel, or PVC. This solution optimizes both the formwork material and the support device structure. However, this formwork is also custom-made for a specific construction scenario.

[0004] In the existing technology, there is no modular design scheme for trench formwork. Utility Model Content

[0005] The purpose of this utility model is to address the technical problems existing in the prior art by providing a movable adjustable trench template that is simple in structure, convenient in construction, and has improved versatility.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A movable adjustable trench template includes a support base, a main base plate, an adjustable crossbar, a lateral positioning component, a liquid level gauge, and a connecting assembly. One or two main base plates are arranged vertically to form template units, and these template units are arranged sequentially in the front-to-back direction to form a template. Adjacent main base plates are connected by the connecting assembly. The support base is located at the bottom of the trench and includes an inner positioning part and an outer positioning part, which respectively position two templates corresponding to one side wall of the trench. The adjustable crossbar is placed on four templates corresponding to the two side walls of the trench. The adjustable crossbar is equipped with an adjustable lateral positioning component for positioning the templates. A liquid level gauge for monitoring the levelness is located in the middle of the adjustable crossbar.

[0008] As a preferred option, a positioning groove is excavated at the bottom of the trench, and an inner positioning part and an outer positioning part are formed on both sides of the positioning groove.

[0009] As a preferred embodiment, the main substrate includes a flat plate portion and a grid-like rib portion disposed on one side surface of the flat plate portion.

[0010] As a preferred embodiment, the rib portion located at the edge of the flat plate portion is provided with a connection hole; the connection component is a connection bolt that mates with the connection hole, and adjacent main substrates are connected by the connection bolt.

[0011] As a preferred embodiment, the rib portion on the same side has at least two or more connecting holes.

[0012] As a preferred embodiment, the lateral positioning component includes a wedge block and a movable positioner; the adjustable crossbar is a square tube, and the adjustable crossbar has multiple vertically penetrating positioning holes, which are spaced apart along the length of the adjustable crossbar, and the wedge block is inserted into the positioning holes; the movable positioner has a horizontally penetrating square hole through which the adjustable crossbar passes.

[0013] As a preferred embodiment, the movable positioner includes a connecting portion with a square hole and a right-angled trapezoidal portion for positioning the template.

[0014] As a preferred embodiment, a movable adjustable trench template further includes an inclined support, one end of which is fixed to the ground and the other end of which is fixed to the template.

[0015] As a preferred option, the two templates on one side wall of the trench are connected by wire.

[0016] As a preferred option, the main substrate is a prefabricated plastic board.

[0017] The principle of this utility model is:

[0018] The width of the trench is controlled by positioning the side wall templates using adjustable crossbars and lateral positioning components; the thickness of the single side wall template is controlled by positioning the single side wall template using support bases; and the height and length of the trench are controlled by connecting the main base plates to form one-row-multiple-column or two-row-multiple-column templates. A liquid level gauge is used to monitor the levelness of both sides in real time to adjust the position and orientation of the templates promptly. Depending on the reinforcement requirements, outriggers and movable positioning devices are installed, and wedge blocks can also serve a reinforcing function.

[0019] This utility model has the following advantages:

[0033] The present invention will be further described in detail below with reference to specific embodiments.

[0034] Example 1

[0035] A movable adjustable trench template includes a support base, a main base plate, an adjustable crossbar, a lateral positioning component, a liquid level gauge, and a connecting assembly. One or two main base plates are arranged vertically to form template units, and these template units are arranged sequentially in the front-to-back direction to form a template. Adjacent main base plates are connected by the connecting assembly. The support base is located at the bottom of the trench and includes an inner positioning part and an outer positioning part, which respectively position two templates corresponding to one side wall of the trench. The adjustable crossbar is placed on four templates corresponding to the two side walls of the trench. The adjustable crossbar is equipped with an adjustable lateral positioning component for positioning the templates. A liquid level gauge for monitoring the levelness is located in the middle of the adjustable crossbar.

[0036] In this embodiment, the main substrate is provided with two template units in the vertical direction. Each unit is 50cm high, and the two units together are 100cm high, which can be used to cast a trench 100cm deep.

[0037] A positioning trench is excavated at the bottom of the trench, forming an inner positioning section and an outer positioning section on both sides of the trench.

[0038] The main substrate includes a flat plate portion and a grid-like rib portion disposed on one side surface of the flat plate portion. In this embodiment, the flat plate portion mainly serves as a casting plane, while the rib portion is mainly used to improve strength and as a connecting structure.

[0039] The ribs located at the edge of the flat plate section have connection holes; the connecting components are connecting bolts that mate with the connection holes, and adjacent main substrates are connected by connecting bolts. This embodiment uses bolt connections, which are simple in structure and easy to operate.

[0040] The rib portion along the same edge has at least two or more connecting holes. In this embodiment, for example... Figure 3 and Figure 4 As shown, adjacent main substrates are connected by three connecting bolts along the length of the trench. In the vertical direction, adjacent main substrates are connected by four connecting bolts.

[0041] The lateral positioning component includes a wedge block and a movable positioner. The adjustable crossbar is a square tube with multiple through-holes arranged at intervals along its length. The wedge block is inserted into these holes. The movable positioner has a transverse through-hole for the adjustable crossbar to pass through. In this embodiment, a wedge block is placed on the inner side of each of the two templates corresponding to a single-sided trench, and a movable positioner is placed between the wedge block and the template. Because the adjustable crossbar has multiple positioning holes, the wedge block can be inserted into the appropriate positioning hole according to the position of the template. The inner template is positioned by the wedge block and the movable positioner.

[0042] The movable positioner includes a connecting part with a square hole and a right-angled trapezoidal part for positioning the template. In this embodiment, the movable positioner can slide along an adjustable crossbar. Since the right-angled trapezoidal part has a relatively long length in the vertical direction, it can play a better role in fixing the template and preventing it from tipping over.

[0043] A movable adjustable trench formwork also includes an inclined support, one end of which is fixed to the ground and the other end to the formwork. In this embodiment, a support is provided on the outer side of the two formwork panels corresponding to a single trench to prevent the formwork from tipping over. The upper end of the support is clamped to the rib plate. The fixing effect of the wedge block, the movable locator, and the support is progressively enhanced and can be selected according to requirements.

[0044] The two templates on one side wall of the trench are connected by wire. In this embodiment, wire is installed at the weakest point to prevent the template from tipping over. Wire binding holes are provided in the rib section for wire binding.

[0045] The main substrate is a prefabricated plastic board.

[0046] In addition, some curved substrates will be customized according to the terrain conditions of the trench to meet the needs of changing the direction of the trench. The difference between the curved substrate and the main substrate is that the curved plate is used instead of the flat plate to adapt to the needs of changing the direction of the trench.

[0047] By adopting this mobile adjustable trench formwork, modular design can be considered during the trench design phase, and the mobile adjustable trench formwork can be directly introduced for installation, effectively improving construction efficiency. Standardized operations can be carried out subsequently, and the utilization rate of the mobile adjustable trench formwork can also be increased.

[0048] Example 2

[0049] In this embodiment, a template unit with a height of 50cm is provided on the main substrate in the vertical direction, which can be used to cast a trench 50cm deep. A wedge-shaped block is provided on the inner and outer sides of the two templates corresponding to the trench on one side, and a movable locator is also provided between the inner wedge-shaped block and the template.

[0050] In addition to the methods mentioned in the above embodiments, the main substrate can be configured with other sizes. These variations are all within the protection scope of this utility model.

[0051] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
