Description

Technical Field

[0002] The building formwork system emphasizes the rapid erection and dismantling of the structure. It is usually composed of modular units that can be quickly installed and removed. It is suitable for projects that require efficient construction. In the steel formwork system, tension bolts are a very important component. They are mainly used to fix and connect the two building formworks to ensure that the building formwork does not shift or deform during the concrete pouring process. Usually, before installing the tension bolts, the formwork needs to be accurately positioned and fixed in the appropriate position. Then, the tension bolts are passed through the holes on the formwork and fixed to the formwork. However, during actual installation, it is difficult to accurately fix the position of the formwork in one go. Minor adjustments are required when installing the tension bolts. If some of the tension bolts are tightened first, the position of the formwork will be fixed. If the formwork is slightly tilted, other tension bolts may not be installed in place, affecting the construction of the formwork system. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] An embodiment of an easily fixed building template system of the present invention is as follows Figures 1 to 9 As shown, it includes a building template and tension bolts 200.

[0029] Two building templates are arranged face-to-face: a first template 110 and a second template 120. Diagonal braces 130 are installed on the sides of the first and second templates 110, 120 facing away from each other. Both templates have through-holes. A first conical cylinder 122, with its larger end facing the first template 110, is fixed to the end of the through-hole of the second template 120 that faces the first template 110.

[0030] There are multiple tension bolts 200 for connecting two building templates, including a first screw rod 210, an intermediate screw rod 220, a connecting assembly and a second screw rod 230.

[0031] The first screw 210 passes through the through-hole of the first formwork 110 and is connected to the intermediate screw 220 located between the two building forms via a first nut 211. The other end of the intermediate screw 220 is connected to the second screw 230, which passes through the through-hole of the second formwork 120, via a connecting assembly. The connecting assembly includes a second tapered barrel 240, a connector 250, and a pull cord 260. The second tapered barrel 240 is provided with a spring 241, and the connector 250 is connected to the second screw 230 via a pull cord 260 that passes through the second tapered barrel 240. In the initial state, the second conical tube 240 is engaged with the connecting member 250 through the spring piece 241, and the second screw 230 is slidingly matched with the second conical tube 240; when the second conical tube 240 is matched with the first conical tube 122, the spring piece 241 is magnetically attracted to the first conical tube 122 and disengaged from the connecting member 250, allowing the connecting member 250 to move relative to the second conical tube 240; the second screw 230 is moved, and the connecting member 250 is driven to move by the pull rope 260 so that it abuts against the second conical tube 240, thereby limiting the relative movement of the connecting member 250 and the second conical tube 240.

[0032] When installing the easy-to-fix building formwork system of the present invention, it is necessary to first place the first formwork 110 vertically and support it with the diagonal braces 130 on its side to keep it vertical, then horizontally pass the first screw 210 through the first formwork 110 and fix it, and make the intermediate screw 220, the connecting assembly and the second screw 230 located on the side of the first formwork 110 away from its diagonal brace 130. After all first screws 210 of the tension bolts 200 are installed on the first template 110, the second template 120 is placed vertically and as parallel to the first template 110 as possible. The spacing between the second template 120 and the first template 110 is adjusted so that each through-hole in the second template 120 corresponds to a tension bolt 200. The second screws 230 of the tension bolts 200 are inserted into the through-holes of the second template 120 along the first conical tube 122. During the adjustment of the second template 120, some second conical tubes 240 of the tension bolts 200 will first engage with the first conical tube 122 of the second template 120. The spring pieces 241 in the second conical tubes 240 that first engage with the first conical tube 122 are magnetically attracted to the first conical tube 122, and then disengage from the connector 250. This will not hinder the movement of the second template 120 during subsequent adjustment until the second template 120 is parallel to the first template 110. After the second template 120 is in place, it is positioned and supported by its corresponding diagonal braces 130. Finally, pull the second screw 230 to move it away from the first template 110. The second screw 230 drives the connecting piece 250 to deflect through the pull rope 260 so that it abuts against the second conical cylinder 240, limiting the relative movement of the connecting piece 250 and the second conical cylinder 240. Then, fix the second screw 230 to the second template 120, and fix the various components of the tension bolt 200 to form a whole.

[0033] By setting up a connecting component, and when the second conical cylinder 240 of the partial connecting component is matched with the first conical cylinder 122, the second conical cylinder 240 of the partial connecting component is disengaged from the connecting piece 250, which does not affect the subsequent movement and adjustment of the second template 120. After the second template 120 is adjusted into place, the connecting piece 250 is abutted against the second conical cylinder 240 through the second screw 230 and the pull rope 260 to limit their relative movement and complete the installation of the tension bolt 200.

[0034] In this embodiment, the connecting member 250 includes a third conical cylinder 251, a second nut 252 and a clamping rod 253. The large end of the third conical cylinder 251 faces the second conical cylinder 240 and is used to abut against the second conical cylinder 240; the clamping rod 253 is located inside the third conical cylinder 251 and abuts against the other end of the intermediate screw 220, and is connected to the intermediate screw 220 through the second nut 252; the second nut 252 is located inside the third conical cylinder 251 and abuts against the third conical cylinder 240. The small ends of the three conical tubes 251 are connected; one end of the pull rope 260 is fixed and wrapped around the clamping rod 253; the clamping rod 253 has an annular slot formed on its outer surface; one end of the spring clip 241 is connected to the inner wall of the second conical tube 240, and the other end extends into the interior of the second conical tube 240 and toward the small end to engage with the slot, thereby maintaining the connection between the connector 250 and the second conical tube 240; the spring clip 241 deforms and disengages from the slot when magnetically attracted to the first conical tube 122. The spring clip 241 is made of a magnetically attracted metal material, such as iron, nickel, cobalt, or alloys thereof. The first conical tube 122 can be made of a magnet or have a magnetic material fixed to its inner surface.

[0035] In this embodiment, a guide cone 123 is provided at the end of the through hole of the second template 120 away from the first template 110, and the large end of the guide cone 123 faces the side away from the first template 110, providing space for pulling out the second screw 230, so that the second screw 230 can be pulled out manually.

[0036] In this embodiment, a tapered sleeve 124 and a drive nut 125 are detachably mounted within the guide cone 123 of the second template 120. The tapered sleeve 124 engages the tapered surface of the guide cone 123 and provides a perpendicular contact surface for the drive nut 125 to contact the second screw 230. During use, one end of the second screw 230 is first pulled out of the through-hole of the second template 120, and the drive nut 125 is then sleeved over the second screw 230. The drive nut 125 is rotated to cause the second screw 230 to move further away from the connector 250. When the second tapered cylinder 240 contacts the third tapered cylinder 251, the drive nut 125 secures the second screw 230 to the second template 120.

[0037] In this embodiment, the large ends of the second tapered tube 240 and the third tapered tube 251 abut against each other, and one abutting surface includes a tapered slope, which guides the third tapered tube 251 to remain coaxial with the second tapered tube 240 when approaching the second tapered tube 240.

[0038] In this embodiment, the abutting surface of the second tapered tube 240 and the third tapered tube 251 further includes an abutting plane. This abutting plane is perpendicular to the axis of the third tapered tube 251 and is located on the outer edge of the tapered slope. Together with the tapered slope, it forms a curved surface. The curved surface increases the abutting area between the second tapered tube 240 and the third tapered tube 251. The abutting plane also prevents the second tapered tube 240 and the third tapered tube 251 from excessively fitting along the tapered slope.

[0039] In this embodiment, multiple spring pieces 241 are spaced apart circumferentially around the second conical cylinder 240, and their ends away from the slots are connected by a fixing ring connected to the inner wall of the second conical cylinder 240. A pull rope 260 passes between two adjacent spring pieces 241 and is connected to the second screw 230.

[0040] In this embodiment, the first nut 211 is located between two building templates, including a tapered sleeve and an inner threaded sleeve located on the inner side of the tapered sleeve and fixedly connected to the small end of the tapered sleeve. The large end of the tapered sleeve abuts against the first template 110. The inner threaded sleeve is used to connect the intermediate screw 220 and the first screw 210, and the outer peripheral wall of the inner threaded sleeve is a polygonal cylindrical surface so that the inner threaded sleeve and the tapered sleeve can be removed by tools; the end of the first screw 210 extending outside the first template 110 is fixed to the first template 110 by a third nut 212.

[0041] In this embodiment, the outer peripheral wall of the clamping rod 253 is provided with a multi-prism surface so that the connecting member 250 can be installed or removed by using a tool.

[0042] During installation of the easily fixed building formwork system of the present invention, the first formwork 110 is first placed vertically and supported by its side braces 130 to maintain the vertical position. After connecting the first screw rod 210 and the intermediate screw rod 220 with the first nut 211, the first screw rod 210 is passed horizontally through the first formwork 110 and secured with the third nut 212. The intermediate screw rod 220, the connecting assembly, and the second screw rod 230 are positioned on the side of the first formwork 110 away from the braces 130, with the large end of the tapered sleeve of the first nut 211 abutting against the first formwork 110. After all the first screw rods 210 of the tension bolts 200 are installed with the first formwork 110, the second formwork 120 is placed vertically and as parallel to the first formwork 110 as possible. The spacing between the second formwork 120 and the first formwork 110 is adjusted so that each through-hole in the second formwork 120 corresponds to a tension bolt 200, and the second screw rods 230 of the tension bolts 200 enter the through-holes in the second formwork 120 along the first tapered barrel 122. During adjustment of the second template 120, the second conical tubes 240 of some of the tension bolts 200 will first engage with the first conical tubes 122 on the second template 120. The spring pieces 241 in the second conical tubes 240 that first engaged with the first conical tubes 122 are magnetically attracted to the first conical tubes 122 and subsequently disengaged from the connector 250. This prevents the movement of the second template 120 from being hindered during subsequent adjustment of the second template 120 until the second template 120 is parallel to the first template 110. Once the second template 120 is in place, it is positioned and supported by its corresponding diagonal braces 130. Finally, the second screw 230 is pulled to move it away from the first template 110. The second screw 230 drives the connector 250 to deflect through the pull rope 260 so that it abuts against the second tapered cylinder 240, limiting the relative movement of the connector 250 and the second tapered cylinder 240. Then, the second screw 230 and the second template 120 are fixed by the tapered sleeve 124 and the transmission nut 125. The various components of the tension bolt 200 are fixed to form a whole. Then, concrete can be poured between the two building templates. After the concrete solidifies, it forms a building wall.

[0043] During dismantling, it is necessary to first remove the diagonal braces 130 of the two building templates and the drive nuts 125 and the third nuts 212 on the two building templates. After the building templates are removed, the first screw 210 and the first nut 211 are removed in turn, and the second screw 230 together with the second tapered cylinder 240 and the connecting piece 250 are removed from the building wall. The intermediate screw 220 can be left in the building wall, and the holes at both ends of the intermediate screw 220 on the building wall can be waterproofed and sealed, or the intermediate screw 220 can be destroyed and removed by a drilling device, and the hole where the intermediate screw 220 is located can be filled.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
