Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a formwork support device for elevator shafts. Background Technology

[0002] In the construction of elevator machine room floor slab formwork, the foundation of the formwork is usually constructed by pre-embedding U-shaped anchor bars in the floor slab or reserving openings in the inner wall of the elevator shaft, and passing through a continuous support beam according to the width of the shaft. The support beam is then fixed to the reserved opening or U-shaped anchor bar by tightening it with wooden wedges.

[0003] Traditional methods of pre-reserving openings require sealing the openings later, which increases the construction process and poses a risk of leakage.

[0004] The traditional method of pre-reserving U-shaped anchor bars results in a long support beam resting on the floor slab, which is limited by the small space in some construction sites and significantly increases the length of the support beam, thus raising material costs. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a formwork support device for elevator shafts, which uses the cooperation of the extension section and the stop to lock and limit the support beam, without the need to reserve anchor bars or reserved openings.

[0006] To achieve the above objectives, the present invention adopts a formwork support device for elevator shafts, comprising multiple support beams spaced apart, each support beam having a length greater than the depth of the elevator shaft. The first end of each support beam abuts against the inner wall of the elevator shaft on the side relatively away from the elevator opening, and the second end of each support beam passes through the elevator opening and rests on the floor slab. Each support beam is equipped with an adjustable stop member for stopping at the lower edge of the elevator opening to limit the support beam.

[0007] A further improvement of this utility model for a formwork support device for elevator shafts is that the formwork support device further includes a support plate for erecting the formwork, and the support plate is connected to multiple support beams.

[0008] A further improvement of this utility model for the formwork support device for elevator shafts is that the first end of the support beam extends upward and forms an extension section for abutting against the inner wall of the elevator shaft on the side relatively far from the elevator opening.

[0009] A further improvement of this utility model for the formwork support device for elevator shafts is that an anti-slip pad is connected to the side of the extension section that is relatively far away from the support beam.

[0010] A further improvement of this utility model for the formwork support device for elevator shafts is that a first stiffening plate is connected at the inside corner of the extension section and the support beam.

[0011] A further improvement of this utility model for a formwork support device in an elevator shaft is that the abutment includes:

[0012] A sliding sleeve is slidably fitted onto the support beam. The sliding sleeve includes a first through hole and a second through hole that are interconnected. The first through hole is adapted to the cross-section of the support beam, and the second through hole is located at the top of the first through hole.

[0013] A baffle, connected to the bottom of the sliding sleeve, is used to block the lower edge of the elevator opening;

[0014] The wooden block is inserted into the second through hole and is press-fitted with the second through hole. The wooden block contacts and abuts against the support beam at the connection between the first through hole and the second through hole. The sliding sleeve is locked by the static friction between the wooden block and the support beam.

[0015] A further improvement of this utility model for the formwork support device for elevator shafts is that the second end of the support beam is connected to an anti-detachment protrusion to prevent the sliding sleeve from detaching from the support beam.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] The support beam is locked in place by the cooperation of the extension section and the retaining member, eliminating the need for pre-reserved anchor bars or openings, thus improving construction efficiency. Attached Figure Description

[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0024] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the formwork support device for elevator shafts according to this utility model.

[0025] Please see Figures 1-3 A formwork support device for an elevator shaft includes multiple support beams 1 spaced apart. The length of each support beam 1 is greater than the depth of the elevator shaft. The first end of each support beam 1 abuts against the inner wall of the elevator shaft on the side relatively away from the elevator opening. The second end of each support beam 1 passes through the elevator opening and rests on the floor slab. Each support beam 1 is equipped with an adjustable stop member to stop at the lower edge of the elevator opening to limit the position of the support beam 1.

[0026] By setting up the abutment and placing it against the lower edge of the elevator shaft, the first end of the support beam 1 is always pressed against the inner wall of the elevator shaft. When the support beam 1 tends to rotate downwards, the upper edge of the first end of the support beam 1 is engaged with the inner wall of the elevator shaft, ensuring the connection stability of the support beam 1.

[0027] Preferably, the formwork support device further includes a support plate for erecting the formwork, the support plate being connected to the plurality of support beams 1.

[0028] This support plate is provided so that the formwork can be supported on it.

[0029] Preferably, the first end of the support beam 1 extends upward and forms an extension 2 for abutting against the inner wall of the elevator shaft on the side relatively away from the elevator opening.

[0030] By setting this extension section, when the support beam 1 has a tendency to rotate downwards, the extension section is engaged with the inner wall of the elevator shaft, further enhancing the connection stability of the support beam 1.

[0031] Preferably, the side of the extension 2 that is relatively far from the support beam 1 is connected to an anti-slip pad.

[0032] By installing the anti-slip pad, the static friction between the extension section 2 and the inner wall of the elevator shaft is enhanced, further strengthening the stability of the support beam 1.

[0033] Specifically, the anti-slip mat is an elastic element.

[0034] By making the protective pad an elastic element, it acts as a buffer, preventing stress concentration from damaging the inner wall of the elevator shaft.

[0035] Preferably, the extension section 2 is connected to the inside corner of the support beam 1 by a first stiffening plate 3.

[0036] By setting the first stiffening plate 3, the strength of the extension section 2 is improved, ensuring the stability of the support beam 1.

[0037] Preferably, the stop includes:

[0038] The sliding sleeve 4 is slidably sleeved on the support beam 1. The sliding sleeve 4 includes a first through hole 9 and a second through hole 10 that are interconnected. The first through hole 9 is adapted to the cross section of the support beam 1, and the second through hole 10 is located at the top of the first through hole 9.

[0039] Baffle 5, connected to the bottom of the sliding sleeve 4, is used to block the lower edge of the elevator opening;

[0040] The wooden block 7 is inserted into the second through hole 10 and is interference-fitted with the second through hole 10. The wooden block 7 contacts and abuts against the support beam 1 at the connection between the first through hole 9 and the second through hole 10. The sliding sleeve 4 is locked by the static friction between the wooden block 7 and the support beam 1.

[0041] By interfering with the second through hole 10, the wooden block 7 and the support beam 1 completely block the space inside the sliding sleeve 4, thereby preventing the sliding sleeve 4 from sliding and locking the position of the sliding sleeve 4.

[0042] like Figure 3 As shown: the first through hole 9 is a rectangular through hole, and the second through hole 10 is a semi-circular through hole. The length of the straight side at the bottom of the semi-circular through hole is equal to the length of the straight side at the top of the rectangular through hole.

[0043] By restricting the shape of the first through hole 9 and the second through hole 10, the support beam 1 can only slide within the first through hole 9 and not enter the second through hole 10, thus ensuring the sliding stability of the sliding sleeve 4 and not affecting the insertion and positioning effect of the timber 7.

[0044] Specifically, a second stiffening plate 6 is connected between the baffle 5 and the sliding sleeve 4.

[0045] By setting the second stiffening plate 6, the strength of the baffle 5 is improved, ensuring the stability of the support beam 1.

[0046] Preferably, the second end of the support beam 1 is connected to an anti-detachment protrusion 8 to prevent the sliding sleeve 4 from detaching from the support beam 1.

[0047] By setting the anti-slip protrusion 8, the sliding sleeve 4 is prevented from slipping off the second end of the support beam 1, thus improving practicality.
