Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building construction template fixing device. Background Art

[0002] After the building formwork is assembled, it is necessary to use a fixing device to fix the building formwork to avoid the problem of the formwork breaking when pouring concrete.

[0003] The fixing device of the cylindrical wooden formwork is usually a flexible metal plate, with connecting blocks fixed at both ends of the metal plate. After the flexible metal plate is wrapped around the cylindrical wooden formwork, the connecting blocks at both ends are connected by bolts, so that the metal plate hugs the circular wooden formwork tightly, so that when pouring concrete, the concrete presses the formwork outward, and the metal plate hugs the formwork tightly, avoiding the problem of formwork cracking. However, the above cylindrical wooden formwork fixing device has the following defects when in use:

[0004] When in use, it is necessary to select a flexible metal plate of appropriate length according to the diameter of the cylindrical template. It is not universal for cylindrical templates with large diameter differences. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0006] Therefore, one purpose of the utility model is to provide a construction formwork fixing device, aiming to solve the problem that the cylindrical wooden formwork fixing device in the prior art is not universal for cylindrical formworks with greatly different diameters.

[0007] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one hand provides a construction template fixing device, comprising a plurality of short rods and a plurality of screw rods, wherein the screw rods are slidably connected in the short rods, and characterized in that both ends of the short rods are fixedly connected with connecting components, and two adjacent short rods are detachably connected together through the connecting component, and the outer surface of the screw rod is slidably sleeved with a support plate, and the outer surface of the screw rod is threadedly connected with a nut, and the support plate is located between the nut and the short rod, and one end of the screw rod is fixedly connected with a top plate.

[0008] Preferably, any of the above schemes comprises two positioning plates, a connecting column and a hook, the two positioning plates are respectively fixedly connected to the upper and lower sides of one end of the short rod, and a connecting column is fixedly connected between the two positioning plates, and the end of the short rod away from the positioning plate is fixedly connected to the hook, and the hook can be directly hung on the connecting column, which is easy to connect.

[0009] Preferably, any of the above schemes is in the shape of an arc, and the arc-shaped top plate has a larger contact area with the cylindrical template surface, so that the fixing stability is better.

[0010] Preferably, any of the above schemes is that the top plate is U-shaped, and a long rod is inserted into the U-shaped top plate. A plurality of the long rods support the cylindrical formwork, thereby increasing the longitudinal supporting force and further improving the reliability of the fixation. Due to the limitation of the long rods, when the concrete is poured inside the formwork and vibrates, the screw itself will not rotate slightly, thereby avoiding the problem of the screw loosening and causing the fixing device to fall off.

[0011] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0012] 1. Two adjacent short rods can be connected end to end through a connecting assembly. The structure is simple and flexible, and can be applied to cylindrical templates of different diameters, with universality.

[0013] 2. The connection assembly includes a connection column and a hook. When connecting two short rods end to end, it is only necessary to put the hook on the surface of the connection column to complete the end-to-end connection of the two adjacent short rods. The connection is simple and can improve assembly efficiency.

[0014] 3. By setting the top plate to an arc or U shape, the contact area between the supporting part and the template can be increased, the stable supporting force can be improved, and the problem of the top plate driving the screw to rotate due to vibration, causing the fixing device to loosen and fall off, can be avoided, further improving stability.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The utility model provides a device for fixing a building construction template.

[0024] Embodiment 1:

[0025] like Figure 1-3 As shown, it includes a plurality of short rods 1 and a plurality of screw rods 2, and the screw rods 2 are slidably connected in the short rods 1, and are characterized in that two ends of the short rods 1 are fixedly connected with connecting components 3, and two adjacent short rods 1 are detachably connected together through the connecting components 3. According to the diameter of the cylindrical template, an appropriate number of short rods 2 can be selected for end-to-end connection, and then the template is surrounded. The outer surface of the screw rod 2 is slidably sleeved with a support plate 21, and a through hole 11 is opened in the middle of the short rod 1. The screw rod 2 is slidably inserted in the through hole 11, and the outer surface of the screw rod 2 is threadedly connected with a nut 22, and the support plate 21 is located between the nut 22 and the short rod 1. One end of the screw rod 2 is fixedly connected with a top plate 23, and the nut 22 is rotated to move the screw rod 2 toward the template, so that the top plate 23 can be pressed against the surface of the template, thereby achieving the purpose of fixing the template.

[0026] Embodiment 2:

[0027] like Figure 1-2 As shown, on the basis of embodiment one, the connecting component 3 includes two positioning plates 31, a connecting column 32 and a hook 33. The two positioning plates 31 are respectively fixedly connected to the upper and lower sides of one end of the short rod 1, and a connecting column 32 is fixedly connected between the two positioning plates 31. The end of the short rod 1 away from the positioning plate 31 is fixedly connected with the hook 33. It is only necessary to put the hook 33 on the surface of the connecting column 32 to complete the end-to-end connection of the two adjacent short rods 1. The connection is simple and the assembly efficiency can be improved.

[0028] Embodiment three:

[0029] On the basis of the first or second embodiment, the top plate 23 is in an arc shape, and the arc-shaped top plate 23 can fit more fully with the surface of the cylindrical template, thereby providing a more stable supporting force.

[0030] Embodiment 4:

[0031] like Figure 1 and Figure 3 As shown, based on Example 1 or Example 2, the shape of the top plate 23 is U-shaped, and a long rod 4 is inserted into the U-shaped top plate 23. The U-shaped top plate 23 can limit the long rod 4 so that it will not tip over to the sides, and the long rod 4 can limit the U-shaped top plate 23 so that it will not rotate.

[0032] The working principle of the utility model is as follows: when in use, according to the diameter of the cylindrical template, select an appropriate number of short rods 1 to connect the end to the end through the connecting assembly 3, so that the assembled device can surround the template, and then slide the screw rod 2 into the through hole 11, and rotate the nut 22 to make the U-shaped top plate 23 close to the template. When the top plate 23 is about to abut against the template, put the long rod 4 into the U-shaped top plate 23, and then tighten the nut 22 to make multiple long rods 4 abut against the circular template.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. By setting the connecting component 3, two adjacent short rods 1 can be connected end to end. Therefore, when fixing the cylindrical template, an appropriate number of short rods 1 can be selected for end to end connection so that they can surround the template, and then the nut 22 is rotated so that multiple top plates 23 can support and fix the outer surface of the cylindrical template. The structure is simple and flexible, can be applied to cylindrical templates of different diameters, and has universality.

[0035] 2. The connection assembly 3 includes a connection column 32 and a hook 33. When connecting two short rods 1 end to end, the hook 33 only needs to be put on the surface of the connection column 32 to complete the end to end connection of the two adjacent short rods 1. The connection is simple and can improve the assembly efficiency.

[0036] 3. By setting the top plate 23 to be arc-shaped or U-shaped, the arc-shaped top plate 23 can fit more fully with the surface of the cylindrical template, thereby providing a more stable supporting force, and the U-shaped top plate 23 can be inserted with the long rod 4, so that the long rod 4 supports the circular template, which can also increase the contact area between the supporting part and the template and enhance the stable supporting force. When pouring concrete and vibrating concrete in the template, the template will vibrate, and the arc-shaped top plate 23 is not easy to rotate relative to the template surface due to vibration after being fitted with the template surface. The U-shaped top plate 23 is restricted by the long rod 4 and cannot rotate. Therefore, the problem that the top plate 23 drives the screw 2 to rotate due to vibration, causing the fixing device to loosen and fall off, can be avoided, thereby improving stability.
