The traditional foundation pit formwork is supported by steel pipes or wooden planks, that is, the load is usually transferred by placing oblique wooden planks or boards at the fulcrum.

[0003] The above approach has the following problems: 1. The fulcrum on the foundation pit side is greatly affected by the soil quality, and the fulcrum is prone to uneven deformation, which in turn causes deformation of the formwork; 2. The force-bearing area of ​​the fulcrum on the foundation pit side of the support rod is small, and the stress is relatively concentrated. When pouring concrete, the formwork may slip; 3. There are a large number of support rods, and there is secondary disturbance to the foundation pit soil when setting the support points. Utility Model Content

[0024] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] In the embodiment of the present utility model, Figure 1 , Figure 2 As shown, the assembled triangular reinforcement support frame is used to support the template, and the template has a template lower part, a template middle part and a template upper part from bottom to top, and the support frame includes a base 1, a first support rod 2 and a second support rod 3; the base 1 is supported on the lower part of the template; the first support rod 2 is inclinedly arranged on the base 1, and is used to support the template middle part; the second support rod 3 is spaced from the first support rod 2 and is arranged on the base 1, and is used to support the template upper part;

[0026] In which, the base 1 is connected to the first support rod 2 and / or the second support rod 3 through a first adjustment structure, the first adjustment structure includes a plurality of limiting holes 101 arranged at intervals in the length direction of the base 1, and a first connecting seat 4 arranged on the first support rod 2 and / or the second support rod 3, the first connecting seat 4 can be selectively fixed to any one of the limiting holes 101 to fix the first support rod 2 and / or the second support rod 3 relative to the base 1.

[0027] Specifically, in an embodiment of the utility model, the base 1 is installed on the ground, and one end thereof is used to abut against the lower part of the template; the first support rod 2 and the second support rod 3 are both arranged at the base 1 at an angle to support the middle and upper parts of the template, forming three support points at the upper, middle and lower parts; at the same time, a triangular stable support structure can be constructed between the base 1, the first support rod 2 and the template, and between the base 1, the second support rod 3 and the template, thereby improving the stability of the support frame and the template and preventing the template from deforming and running; furthermore, the first support rod 2 and the second support rod 3 are both connected to the base 1, and the base 1 is used to increase the force-bearing area of ​​the bottom of the first support rod 2 and the bottom of the second support rod 3, which can provide a solid support surface for the template compared to a single diagonal brace, making the support frame structure more stable.

[0028] In the embodiment of the utility model, the bottom of the first support rod 2 and the second support rod 3 are both fixed with a first connecting seat 4 (hereinafter taking the first support rod 2 as an example for explanation), and the base 1 is provided with a plurality of limiting holes 101 at intervals in the length direction (such as: holes are opened every 10 cm). During installation, the limiting holes 101 at appropriate positions are selected, and the first connecting seat 4 is fixed to the limiting holes 101, so that the bottom of the first support rod 2 is fixed to the corresponding position of the base 1, and the top thereof can be directly abutted against the middle of the template; in this way, not only can the versatility of the support frame be improved and the restrictions of the environment on its installation conditions be reduced, but also there is no need to open holes at the support points, thereby avoiding secondary disturbance of the foundation pit, and the installation and disassembly are convenient and recyclable.

[0029] The utility model respectively arranges the second support rod 3, the first support rod 2 and the base 1 at the upper, middle and lower support points of the template to form a triangular stability structure, thereby improving the structural stability of the support frame, thereby preventing the template from being deformed or running out of the template after being installed at the template; at the same time, the first connecting seat 4 and the limiting hole 101 are used to cooperate to fix the first support rod 2 and the second support rod 3 at any length of the base 1, and the base 1 is used to increase the bottom force-bearing area of ​​the first support rod 2 and the second support rod 3, so that the force is clear, the installation and disassembly are convenient, and the installation restrictions imposed by the environment can also be reduced.

[0030] like Figure 2 , Figure 3 As shown, in one embodiment, the first connection seat 4 is a U-shaped structure, the closed end of which is connected to the first support rod 2 and / or the second support rod 3, and the base 1 extends into the open end of the first connection seat 4. Specifically, in order to balance the forces on the first support rod 2 and the second support rod 3, and to improve the connection strength between them and the base 1, this embodiment defines the first connection seat 4 as a U-shaped structure so that it can be sleeved outside the base 1, so that the first support rod 2 or the second support rod 3 is located at the central axis of the first connection seat 4.

[0031] Furthermore, in one embodiment, the base 1 is provided with a slide groove 102 in the length direction, a plurality of limiting holes 101 are formed in the slide groove 102, the open end of the first connecting seat 4 is provided with a pulley 5 matching the slide groove 102, and the pulley 5 is fixed to any one of the limiting holes 101 via a pin shaft 6. Specifically, in order to facilitate the adjustment of the position state of the first support rod 2 and the second support rod 3 at the base 1, the present embodiment sets a slide groove 102 in the length direction of the base 1, and sets a pulley 5 at the first connecting seat 4. The pulley 5 can move in the above-mentioned slide groove 102 under the action of external force to drive the corresponding first support rod 2 or second support rod 3 to move, so as to facilitate adjusting it to a suitable position; on the other hand, in order to facilitate the first support rod 2 and the second support rod 3 to be fixed at any position of the base 1, the pulley 5 is fixed at the corresponding limiting hole 101 by using a pin 6 to position the first support rod 2 and the second support rod 3 by limiting its movement; at the same time, only the pin 6 needs to be removed to move the corresponding support rod to the corresponding limiting hole 101 to complete the support at the corresponding position, which is convenient and labor-saving, and there is no need to adjust the support point position back and forth. The setting of the pin 6 is convenient for loading and unloading, so that the support frame can be recycled. Of course, the base 1 can be made of I-beam, and its slide groove 102 is formed on both sides of the I-beam.

[0032] like Figure 1 , Figure 2 As shown, in one embodiment, a limiting rod 9 is provided at one end of the base 1 away from the lower part of the template, and the limiting rod 9 is perpendicularly arranged with the base 1. Specifically, in order to prevent the base 1 from sliding backward, the embodiment vertically arranges a limiting rod 9 at its end, and the limiting rod 9 is inserted into the ground to limit the movement of the base 1, thereby further improving the stability of the support frame.

[0033] like Figure 1-Figure 3 As shown, in one embodiment, a second adjustment structure is provided between the first support rod 2 and the middle of the template and / or between the second support rod 3 and the upper part of the template, and the second adjustment structure is a threaded rod 7 that is screwed into the first support rod 2 and / or the second support rod 3. Specifically, in order to enable the first support rod 2 and the second support rod 3 to abut against the middle of the template and the upper part of the template respectively, in this embodiment, a threaded rod 7 is screwed on the ends of both, and the threaded rod 7 is coaxially arranged with the corresponding support rod, and the extension amount of the threaded rod 7 is adjusted by rotating the threaded rod 7, so as to compensate for the distance between the corresponding support rod and the template, and to avoid the template from deforming or running out of the mold.

[0034] Furthermore, in one embodiment, the threaded rod 7 is provided with a second connection seat 8, and the second connection seat 8 is formed with an opening arranged in the direction of the template, which is used to be clamped in the middle of the template and / or the upper part of the template. Specifically, in order to improve the connection tightness between the threaded rod 7 and the template, this embodiment is provided with a second connection seat 8 at the end of the threaded rod 7, and the second connection seat 8 is formed with an opening arranged in the direction of the template; in this way, the second connection seat 8 is gradually moved in the direction of the template by rotating the threaded rod 7, so that the opening is clamped at the corresponding height of the template; of course, in order to make the opening fit the template, the second connection seat 8 can be movably connected to the threaded rod 7, so that the opening can always be clamped in the template; on the other hand, the threaded connection method can replace the welding between the rod bodies, reduce the difficulty of on-site construction operations, facilitate installation and disassembly, and the materials can be circulated and recycled, thereby reducing material costs.

[0035] like Figure 2 As shown, in one embodiment, the length of the first support rod 2 and the length of the second support rod 3 are defined as L1 and L2 respectively, satisfying L1<L2, so that the first support rod 2 and the second support rod 3 are supported at corresponding heights of the template, and can also be quickly identified during installation to avoid installation errors.

[0036] Preferably, the surface of the base 1 is defined as a reference plane, and the projections of the first support rod 2 and the second support rod 3 at one end facing away from the base 1 on the reference plane coincide with each other, so as to support the first support rod 2 and the second support rod 3 on the same vertical plane of the template, thereby improving the stability of the template at this location.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
