Description

Technical Field

[0001] This utility model relates to the field of template technology, specifically to a template fixing device for building engineering. Background Technology

[0002] In construction projects, different foundations need to be poured, and formwork is used to shape the concrete and create the design shape and size of the concrete structure.

[0003] In existing technology, the casting base is usually made by installing two templates opposite each other. The two templates are fixed at both ends by long bolts or ropes. For wooden templates, if the length of a single template is long, the two templates are only connected by long bolts at both ends, and there is a lack of sufficient support in the middle. After the concrete is poured, the lateral pressure will cause the middle of the template to bulge outward, resulting in deviations in the concrete forming dimensions. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a formwork fixing device for building engineering.

[0005] The technical solution of this utility model is as follows:

[0006] A formwork fixing device for construction engineering is installed on two symmetrically placed formworks. The formworks are horizontally positioned along their length, and both ends of the two formworks are connected by protective plates. The device includes connecting rods that are perpendicular to the formworks. Both formworks have corresponding elongated installation openings on their upper parts along the vertical direction. The installation openings are adapted to the connecting rods. The connecting rods are inserted into the corresponding installation openings of the two formworks, and the ends of the connecting rods protrude from the outer side of the corresponding formworks. Stop plates are inserted into the installation openings, and the lower ends of the stop plates are in close contact with the outer wall of the connecting rods.

[0007] Both ends of the connecting rod are equipped with a dismantling device, which is connected to the outer side of the corresponding template by a tightening bolt.

[0008] Preferably, the template has multiple sets of installation openings along its length, with the installation openings of two templates being set correspondingly, and each of the corresponding installation openings of the two templates being equipped with a connecting rod.

[0009] The specific structure of the above-mentioned installation opening is as follows: the installation opening is a cross-shaped structure, including a connected longitudinal hole and a transverse groove. The length direction of the transverse groove is consistent with the length direction of the template. The connecting rod is inserted into the longitudinal hole, and the stop plate is inserted into the transverse groove.

[0010] Preferably, the upper end of the stop plate protrudes above the transverse groove.

[0011] Furthermore, the connecting rod is a round rod, and the lower end face of the stop plate is adapted to the outer surface of the connecting rod.

[0012] To reduce the gap between the connecting rod and the longitudinal hole and to reduce concrete leakage, the bottom surface of the longitudinal hole is adapted to the outer surface of the connecting member, and the bottom surface is an arc-shaped bottom surface.

[0013] One structure of the dismantling component is as follows: the dismantling component includes a first connecting plate, one end of which is connected to a connecting rod, and the side away from the first connecting rod is connected to the outer side of the template by a tightening bolt.

[0014] Another structure for the dismantling component is as follows: the dismantling component includes a second connecting plate, one end of which is threaded to the end of the connecting rod, and the two ends of the second connecting plate are connected to the outer side of the template by tightening bolts.

[0015] To facilitate cutting the protruding parts of the connecting rods from the template and to make the template easier to disassemble, a cutting bevel is provided at the end of the connecting rod near the first connecting plate. The cutting bevel is located on the outside of the template. By cutting the connecting rod through the cutting bevel, some connecting rods and disassembly parts can be disassembled and removed, making it easier to disassemble the template.

[0016] Preferably, the length of the installation opening is less than half the width of the template.

[0017] The beneficial effects of this utility model are as follows:

[0018] By inserting connecting rods into the corresponding installation openings of two templates, each connecting rod has a removal part at both ends. The removal part, together with the connecting rod, can connect the two templates. Multiple connecting rods can be provided to strengthen the weaker supporting part in the middle of the two templates, so as to avoid the deformation of the concrete after the two corresponding templates are formed due to the lack of supporting force.

[0019] The removal components are placed on the outside of the formwork to facilitate removal after concrete is poured, thereby enabling rapid dismantling of the formwork.

[0020] The dismantling component has two structures. One is a first connecting plate that is directly fixed to the connecting rod. The first connecting plate is equipped with tightening bolts. The connecting rod is installed between the two templates by tightening bolts on both sides. It is also used to strengthen the connection between the two templates. This structure has a cutting bevel at the end of the connecting rod for quick removal of parts protruding from the template without affecting the use of the forming base. The other dismantling component has a second connecting plate that is detachably connected to the end of the connecting rod. It can be dismantled without cutting, so that the dismantling component can be reused. Attached Figure Description

[0032] Example 1

[0033] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a formwork fixing device for construction engineering is installed on two symmetrically placed formworks 1. The formworks 1 are horizontally positioned along their length. Both ends of the two formworks 1 are connected by protective plates, and long bolts are inserted between the two formworks 1 to clamp the protective plates. The two formworks 1 can also be spliced ​​together according to the actual situation of the base. This utility model is a fixing connection design for two longer formworks 1 in the base formwork 1 section. The formwork 1 fixing device of this utility model includes connecting rods 2 vertically connected to the formworks 1. The upper part of the two formworks 1 has corresponding elongated installation openings along the vertical direction. The installation openings are adapted to the connecting rods 2. The connecting rods 2 are inserted into the corresponding installation openings of the two formworks 1, and the ends of the connecting rods 2 protrude from the outer side of the corresponding formwork 1. Stop plates 3 are inserted into the installation openings, and the lower end of the stop plates 3 is in close contact with the outer wall of the connecting rods 2.

[0034] Both ends of the connecting rod 2 are equipped with dismantling parts, which are connected to the outer side of the corresponding template 1 by tightening bolts 4.

[0035] Preferably, the template 1 has multiple sets of installation openings along its length, with the multiple sets of installation openings evenly distributed along the length of the template 1. The installation openings of two templates 1 are correspondingly arranged, and each of the corresponding installation openings of two templates 1 is provided with a connecting rod 2. In this embodiment, the length of the installation opening is less than half the width of the template 1, to avoid reducing the strength of the template 1 due to the installation opening being too long.

[0036] In the above structure, by inserting the connecting rod 2 into the corresponding installation openings of the two templates 1, each connecting rod 2 has a removal component at both ends. The removal component, together with the connecting rod 2, can connect the two templates 1. Multiple connecting rods 2 can be provided to reinforce the weaker supporting area between the two templates 1, preventing deformation of the concrete after molding due to insufficient support between the two corresponding templates 1.

[0037] See Figure 5 As shown, the specific structure of the above-mentioned installation opening is as follows: the installation opening is a cross-shaped structure, including a connected longitudinal hole 101 and a transverse groove 102. The length direction of the transverse groove 102 is consistent with the length direction of the template 1. The connecting rod 2 is inserted into the longitudinal hole 101. The stop plate 3 is inserted into the transverse groove 102. The stop plate 3 is adapted to the transverse groove 102, and the length of the stop plate 3 is slightly greater than the length of the transverse groove 102, so that the upper end of the stop plate 3 protrudes above the transverse groove 102. This makes it convenient to press the stop plate 3 downward with a tool when it is vertically inserted into the transverse groove 102, thus avoiding the phenomenon that the stop plate 3 is too short and it is not easy to move the stop plate 3 downward.

[0038] See Figure 8 As shown, in order to reduce the gap at the connection between the connecting rod 2 and the longitudinal hole 101 and reduce the outflow of concrete, the connecting rod 2 in this embodiment is a round rod, the lower end face of the stop plate 3 is adapted to the outer surface of the connecting rod 2, and the lower end face of the stop plate 3 is an arc-shaped pressing surface 301; and the bottom surface of the longitudinal hole 101 is adapted to the outer surface of the connecting member, and the bottom surface is an arc-shaped bottom surface 1011.

[0039] See Figure 2As shown, one structure of the dismantling component includes a first connecting plate 5. One end of the first connecting plate 5 is connected to the connecting rod 2, and the side away from the first connecting rod 2 is connected to the outer side of the template 1 via a tightening bolt 4. To facilitate cutting the portion of the connecting rod 2 protruding from the template 1 and to facilitate the dismantling of the template 1, a cutting bevel 201 is provided at the end of the connecting rod 2 near the first connecting plate 5. Two vertically distributed cutting bevels 201 are provided at both ends of a single connecting rod 2. The cutting bevels 201 are V-shaped or W-shaped structures and are located on the outside of the template 1. By cutting the cutting bevels 201 of the connecting rod 2, part of the connecting rod 2 and the dismantling component can be disassembled and removed, facilitating the dismantling of the template 1.

[0040] Example 2

[0041] See Figure 6 and Figure 7 As shown, the difference between Embodiment 2 and Embodiment 1 lies in the dismantling components. In this embodiment, the dismantling component includes a second connecting plate 6. The end of the connecting rod 2 is provided with external threads, and the second connecting plate 6 has threaded holes adapted to the external threads. One end of the second connecting plate 6 is threadedly connected to the end of the connecting rod 2, and both ends of the second connecting plate 6 are connected to the outer side of the template 1 via tightening bolts 4. This allows the tightening bolts 4 and the second connecting plate 6 to be removed separately after concrete pouring and before template 1 removal, and the second connecting plate 6 can be reused.
