[0003] In foundation pits where the surrounding environment has strict requirements on deformation, a support method combining cast-in-place piles with internal supports is often used. The internal support beams are generally reinforced concrete structures, which can be connected to the cast-in-place piles by pre-reserved steel bars or embedded steel bars.

If the engineering pile is higher than the inner support beam and is located directly below the inner support beam, the side of the inner support beam is easily affected, thereby affecting the support effect and strength of the inner support beam, resulting in poor support strength of the inner support beam.

[0022] Reference Figure 1 and 2 As shown, it is a preferred embodiment provided by the utility model.
[0023] The armpit-type inner support beam 1 comprises an inner support beam 1, an engineering beam 2, a first side armpit 3 and a second side armpit 4. The inner support beam 1 is horizontally extended, the engineering beam 2 is longitudinally extended, and the engineering beam 2 runs through the inner support beam 1 and is connected and fixedly arranged; the inner support beam 1 has a first beam side surface and a second beam side surface, the first side armpit 3 is arranged correspondingly to the first beam side surface, and the second side armpit 4 is arranged correspondingly to the second beam side surface; the first side armpit 3 comprises a plurality of first armpit steel bars, each of which is arranged correspondingly at intervals, and the second side armpit 4 comprises a plurality of second armpit steel bars, each of which is arranged correspondingly at intervals, and the first armpit steel bars and the second armpit steel bars are anchored into the inner support beam 1 respectively.
[0024] The above-mentioned armpit-type inner support beam 1, under the action of the first side armpit 3 and the second side armpit 4, reinforces the two sides of the inner support beam 1, makes the internal force distribution of the inner support beam 1 more reasonable, and at the same time improves the stress condition of the inner support beam 1, thereby improving the support reliability of the inner support beam 1 and improving the support strength of the foundation pit.
[0025] The first axillary reinforcement has a first anchoring section 31, and the second axillary reinforcement has a second anchoring section 41. The first anchoring section 31 and the second anchoring section 41 are respectively anchored inside the inner support beam 1, and the first anchoring section 31 and the second anchoring section 41 are cross-staggered and arranged.
[0026] In this way, under the action of the first anchoring section 31 and the second anchoring section 41, the fixing effect of the first axillary reinforcement and the second axillary reinforcement to the inner support beam 1 is enhanced, so that the first axillary reinforcement and the second axillary reinforcement provide a reinforcing force.
[0027] The first anchoring section 31 and the second anchoring section 41 are arranged vertically and fixedly, and the first anchoring section 31 and the second anchoring section 41 are arranged at 90 degrees; in this way, with the cooperation of the first anchoring section 31 and the second anchoring section 41, the internal force distribution of the inner support beam 1 is made more reasonable, thereby improving the support strength of the inner support beam 1.
[0028] The inner support beam 1 has a plurality of waist reinforcements, and along the width direction of the inner support beam 1, the waist reinforcements are arranged at intervals and in correspondence; under the action of the waist reinforcements, the inner support beam 1 has a supporting force to ensure the support of the foundation pit.
[0029] The first anchoring section 31 and the second anchoring section 41 are respectively arranged in a staggered connection with each waist reinforcement; in this way, the first anchoring section 31 and the second anchoring section 41 are respectively fixed to each waist reinforcement, thereby improving the reinforcement effect of the first anchoring section 31 and the second anchoring section 41, and further improving the support strength of the inner support beam 1.
[0030] Each first anchoring section 31 and each second anchoring section 41 are respectively arranged in a staggered connection with each waist reinforcement, thereby improving the support strength of the inner support beam 1.
[0031] The first arm reinforcement includes a first transverse arm section 33, two first oblique arm sections 32 and two first anchoring sections 31. The two ends of the first transverse arm section 33 are respectively butt-jointed with the two first oblique arm sections 32. The two first oblique arm sections 32 are butt-jointed with the two first anchoring sections 31 in a one-to-one manner. The first oblique arm sections 32 are arranged to extend obliquely, and the first oblique arm sections 32 are arranged outside the inner support beam 1.

[0033] The first transverse axil section 33, the two first oblique axil sections 32 and the two first anchoring sections 31 are integrally formed and arranged, which facilitates the assembly of the first axil reinforcement and ensures the reinforcement effect of the first axil reinforcement.
[0034] The first oblique arm section 32 forms an external angle with the inner support beam 1, and the external angle is arranged at an obtuse angle. In this way, the supporting structure formed by the first oblique arm section 32 and the inner support beam 1 is more stable and reliable.
[0035] Alternatively, the outer angle is arranged at 135 degrees; in this way, the supporting structure formed by the first oblique armpit section 32 and the inner support beam 1 is more stable and reliable.

[0037] Along the width direction of the inner support beam 1, the inner support beam 1 has a beam width, and the length of the first transverse armpit section 33 is arranged consistently with the length of the beam width; the stress on the outer sides of the inner support beam 1 is more uniform, making the overall stress on the inner support beam 1 more uniform, thereby improving the support stability and reliability of the inner support beam 1.
[0038] The first transverse arm sections 33 are arranged in sequence, and the number of rows of the first transverse arm sections 33 is greater than 5 rows; thus, it is ensured that the first transverse arm sections 33 have a sufficient reinforcement range.

[0041] The second transverse axil section, the two second oblique axil sections and the two second anchoring sections 41 are arranged in a two-body molding, which facilitates the assembly of the second axil reinforcement and ensures the reinforcement effect of the second axil reinforcement.
[0042] The second oblique armpit section forms an external angle with the inner support beam 1, and the external angle is arranged at an obtuse angle. In this way, the supporting structure formed by the second oblique armpit section and the inner support beam 1 is more stable and reliable.
[0043] Alternatively, the outer angle is arranged at 135 degrees; in this way, the supporting structure formed by the second oblique axil section and the inner support beam 1 is more stable and reliable.
[0044] A waist reinforcement spacing is formed between adjacent waist reinforcements, a transverse arm spacing is formed between adjacent second transverse arm sections, and the waist reinforcement spacing and the transverse arm spacing are arranged consistently; in this way, the internal force distribution of the inner support beam 1 is consistent with the internal force distribution of the support structure formed by the second transverse arm section, so that the internal force distribution of the overall support structure is consistent, thereby improving the stability of the support structure and ensuring support for the foundation pit.
[0045] Along the width direction of the inner support beam 1, the inner support beam 1 has a beam width, and the length of the second transverse armpit section is arranged consistently with the length of the beam width; the stress on the outer sides of the inner support beam 1 is more uniform, making the overall stress on the inner support beam 1 more uniform, thereby improving the support stability and reliability of the inner support beam 1.
[0046] The second transverse arm sections are arranged in sequence, and the number of rows of the second transverse arm sections is greater than 5 rows; in this way, it is ensured that the second transverse arm sections have a sufficient reinforcement range.

The internal support beam 1, the first side armpit 3 and the second side armpit 4 are respectively in the formwork cavity. The formwork cavity is used for concrete pouring. The concrete is poured synchronously to wrap the internal support beam 1, the first side armpit 3 and the second side armpit 4.
[0048] In this way, the support structure formed after pouring reinforces both sides of the inner support beam 1, makes the internal force distribution of the inner support beam 1 more reasonable, improves the support reliability of the inner support beam 1, and improves the support strength of the foundation pit.
